-# st2 legacy guide
-
-This guide describes the st2 runtime during the Fractal migration.
-
-st2 runs a declarative network of Codex, Claude, and pi agents from one catalog. It owns process
-reconciliation, native messages, normalized terminal DING delivery, presence, durable context,
-workspace materialization, and explicit teardown.
-
-Canonical KDL is the authoring interface. Publish one explicit Agent Spec transactionally with
-`st2 agent publish`; st2 does not compile human intent into declarations.
-
-## Product intent and implementation contract
-
-Read the [vision](docs/vrs/vision.md), [requirements](docs/vrs/requirements.md), and
-[specification](docs/vrs/spec.md) before changing product behavior. Update `docs/vrs/spec.md` with
-implementation changes. Alex must approve changes to `docs/vrs/vision.md` or
-`docs/vrs/requirements.md`.
-
-## Install
-
-Prerequisites:
-
-- Rust and Cargo;
-- `pty` on `PATH` with `pty run --unset-env` support;
-- at least one supported harness on `PATH`: `codex`, `claude`, or `pi`;
-  (`codex` is admitted by an exact version allowlist; `pi` is not version-pinned, but the shipped pi
-  extension is type-checked against a pinned pi release by `nix flake check`);
-- Git when a declaration materializes workspace files;
-- Bash and `jq` on `PATH` when lifecycle hooks are enabled.
-
-From a checkout (`scripts/install` installs st2 together with st3 and the `st` symlink):
-
-```sh
-cargo install --path . --locked
-st2 --help
-pty --help
-st2 hooks install
-st2 hooks verify
-st2 claude-channel install
-st2 claude-channel status
-```
-
-When upgrading, deploy and activate the compatible `pty` before this version of
-`st2`. An older `pty` may silently ignore the unknown `--unset-env` option and
-still launch the agent without persisting the removal. The initial environment
-can therefore look correct while a later restart reintroduces the caller's
-ambient value. The Nix input and development shell pin the compatible artifact;
-Cargo installs rely on the operator to satisfy this runtime prerequisite.
-
-The standard catalog is:
-
-```text
-${XDG_STATE_HOME:-$HOME/.local/state}/st2/default/catalog
-```
-
-Every catalog-aware command accepts `--catalog`; otherwise st2 uses `$CATALOG`, then that standard
-location.
-
-### A catalog may declare its session registry
-
-A catalog's tasks live in `<catalog>/pty` unless the catalog says otherwise. To put several catalogs
-in one host-wide `pty` registry — so any viewer enumerates every session without knowing which
-catalog produced it — declare it in `<catalog>/catalog.kdl`:
-
-```kdl
-catalog {
-  pty-root "/run/agents/pty"
-}
-```
-
-`pty-root` accepts `$VAR`/`$CATALOG`; a relative value anchors at the catalog root. The resolution
-order is an exported `PTY_ROOT` (a deliberate override, used by `st2 eval` for a short socket path),
-then this declaration, then `<catalog>/pty`. A catalog that declares nothing is unaffected.
-
-Prefer the declaration over exporting `PTY_ROOT` into readers: a reader that misses the export
-resolves a different registry and reports live agents as dead. When adopting it on a host whose
-systemd unit was installed with an ambient `PTY_ROOT`, reinstall the unit without one
-(`st2 service install`) — the export still wins, and leaving it pins the supervisor to the old
-registry while everything else follows the catalog.
-
-### A catalog may declare how long retirement is kept
-
-`st2 up` archives retired, quiescent seats itself, so a long-lived catalog stays bounded without
-anyone remembering the chore. The grace period is `archive-after`, declared beside the registry:
-
-```kdl
-catalog {
-  pty-root "/run/agents/pty"
-  archive-after "7d"
-}
-```
-
-It accepts the usual duration spellings (`90`, `30m`, `12h`, `7d`; a bare number is seconds) and
-defaults to `7d`. `archive-after "0"` disables the automatic step without disabling
-`st2 catalog archive`. A value st2 cannot parse fails `st2 validate` rather than falling back to the
-default: archiving on a clock the operator did not write is the one outcome this setting exists to
-prevent.
-
-Each pass archives at most 25 seats, so a catalog holding hundreds of retirements drains over
-several passes, and it never queues for the authoring lock — a pass blocked behind
-`st2 catalog apply` would stall every live agent's reconciliation, and a due seat is still due next
-pass. Because st2 records no timestamp for a desired-state edit, the clock starts when the
-supervisor first observes the retirement; it keeps that observation in
-`<catalog>/.st2/retired-observed.json`, never in the spec, and drops a seat's row as soon as it
-stops being retired — so un-retiring and retiring again serves a fresh grace period.
-
-Lifecycle hooks are installed only by the explicit `st2 hooks install` command. The installer
-publishes an immutable content-addressed set, then atomically selects it with a receipt. `st2 up`
-verifies its own immutable set for Codex launches; any local workspace render that actually
-references `$ST_HOOKS` verifies that set before writing. Selecting a successor does not invalidate
-an older running binary's installed set during cutover. Hook-free materialization does not require
-an installed set. These checks never create, refresh, or rewrite hooks. To select this binary's
-exact hook set when the installed and candidate builds are older or cannot be ordered, use `st2
-hooks install --replace`. `st2 hooks verify-own` is the read-only cutover probe for an installed
-binary that may no longer be selected.
-
-`ST_HOOKS` overrides the machine-local hook root for installation, verification, and managed tasks.
-During materialization, hook commands such as `$ST_HOOKS/codex-stop.sh` resolve to the invoking
-binary's immutable set, so rendered settings are versioned without embedding a machine-specific
-root in the declaration.
-
-The hooks have a small operational purpose: session-start restores durable context and exposes the
-current inbox; pre-compact preserves a recovery breadcrumb when no context was written; stop and
-failure hooks surface newly arrived work or a harness failure. They fail open so hook trouble does
-not prevent the harness from starting or stopping.
-
-`st2 claude-channel install` publishes the Claude Code marketplace and plugin embedded in the st2
-binary. It registers the plugin for the current user and installs one machine policy fragment with
-`sudo`. The policy approves the stable `st2-channel@st2` identity. The plugin starts the st2 MCP
-server through the managed task's `PATH`, `CATALOG`, and `ST_AGENT`; it writes no `.mcp.json` file
-into a product workspace. Re-running the command updates the marketplace and reinstalls the exact
-embedded plugin. `st2 claude-channel status` verifies all four parts. `uninstall` removes only the
-st2 user state and its policy fragment. Installation is optional. When the plugin is absent, the
-native driver passes an inline MCP declaration and uses Claude's development channel. Claude can
-show a confirmation prompt on that path, so install the plugin for unattended agents. Claude treats
-the managed plugin list as an allowlist. Administrators must include any other approved channel
-plugins in their managed policy.
-
-The same immutable set also carries `pi-channel.ts`. pi has no hook mechanism of its own — an
-extension is where a pi session exposes that surface — so st2 ships one and `st2 driver pi-session`
-splices it into the launch from the set this binary verified. A declaration never names it, and a
-host whose selected set predates it is told to run `st2 hooks install` rather than launching
-without a channel. That extension carries the pi equivalent of the session-start hook: st2 composes
-the same restored working state, boot ritual, and unread-inbox listing and puts it on the channel's
-opening frame, and the extension waits for that frame before the session's first turn, so a
-restarted pi agent boots knowing what it was doing. A managed pi seat also runs with `PI_OFFLINE=1`
-and `PI_SKIP_VERSION_CHECK=1` unless its declaration sets them, so a supervised agent does not
-self-update or make its boot latency depend on the network.
-
-## Author a native agent
-
-Start from the maintained [Codex](examples/native/agent-codex.kdl),
-[Claude](examples/native/agent-claude.kdl), or [pi](examples/native/agent-pi.kdl)
-declaration:
-
-```sh
-export CATALOG="${XDG_STATE_HOME:-$HOME/.local/state}/st2/default/catalog"
-bundle="$(mktemp -d)"
-mkdir -p "$bundle/assets"
-cp examples/native/agent-codex.kdl "$bundle/agent.kdl"
-cp ./composed-AGENTS.md "$bundle/assets/AGENTS.md"
-${EDITOR:-vi} "$bundle/agent.kdl"
-input_sha256="$(st2 agent digest --bundle "$bundle")"
-st2 agent publish --catalog "$CATALOG" --bundle "$bundle" \
-  --input-sha256 "$input_sha256" --expect-absent --json
-```
-
-Replace `<host>`, `<identity>`, `<workspace>`, and `<boot prompt>`. Include every file referenced by
-`copy` in the bundle. For a later declaration-only update, publish `agent.kdl` with the current
-declaration's SHA-256 via `--spec ... --expect-sha256 HEX`; sibling assets and state are preserved.
-Bind either operation to the exact captured source with the SHA-256 returned by
-`st2 agent digest`.
-
-To prepare and apply a complete declaration-plane replacement without copying
-runtime state or workspaces:
-
-```sh
-st2 catalog snapshot --catalog "$CATALOG" --output ./prepared --json
-# Edit/render ./prepared. Retain rootSha256 from snapshot as the incumbent CAS,
-# and afterRootSha256 from diff as the exact desired-input CAS.
-st2 catalog diff --catalog "$CATALOG" --prepared ./prepared \
-  --expect-sha256 <rootSha256> --json
-st2 catalog apply --catalog "$CATALOG" --prepared ./prepared \
-  --input-sha256 <afterRootSha256> --expect-sha256 <rootSha256> --json
-```
-
-If the incumbent declarations cannot be parsed or must remain opaque to the
-current parser, bind a one-time repair to their exact structural bytes instead:
-
-```sh
-st2 catalog snapshot --catalog "$CATALOG" --output ./invalid-preimage \
-  --raw-preimage --json
-# Produce a fully valid ./prepared directory from that capture.
-st2 catalog digest --catalog "$CATALOG" --prepared ./prepared --json
-st2 catalog apply --catalog "$CATALOG" --prepared ./prepared \
-  --input-sha256 <rootSha256> --expect-sha256 <raw-rootSha256> \
-  --raw-preimage --json
-```
-
-Raw-preimage mode has its own hash and receipt schemas. It makes no semantic
-assertion about the live bytes—including validity, profiles, the catalog
-envelope, or effective PTY root—while still fully validating the prepared and
-applied catalogs. The caller-supplied raw-domain digest is the exact live
-precondition. This is a byte-oriented transaction, not a validation bypass or
-migration-policy engine.
-
-To publish that exact snapshot as a new, absent catalog:
-
-```sh
-st2 catalog bootstrap --catalog "$NEW_CATALOG" --prepared ./prepared \
-  --input-sha256 <rootSha256> --json
-```
-
-Ordinary `catalog apply` is policy-free. It rejects state/control content,
-symlinks, unprojected workspace facts, catalog-local/default PTY roots, and
-effective PTY-root changes. Raw-preimage apply replaces those live semantic
-checks with its exact byte-domain CAS. Bootstrap is a separate create-only
-declaration transaction, not an apply mode. It atomically publishes absence or
-the complete catalog, initializes its persistent lock and generation before
-visibility, and never reads or writes the external PTY registry. Process
-adoption and PTY-root migration remain separate because that registry has
-independent producers. A crash during apply leaves a durable marker and
-content-addressed stage. `st2 catalog apply --catalog "$CATALOG" --resume --json`
-resumes without the original prepared source. Snapshots own the complete
-bounded `_templates` library and empty canonical per-agent `.workspace`
-directory facts, but never traverse, hash, copy, or delete workspace content.
-
-A retired declaration is runtime teardown only: it keeps its spec and `resources/` byte-identical
-and stays reversible, so a long-lived catalog accumulates retired identities. Archival is the
-pressure valve that keeps the live plane bounded:
-
-```sh
-st2 catalog archive --catalog "$CATALOG" --all-retired --dry-run --json
-st2 catalog archive --catalog "$CATALOG" --identity <identity> --json
-st2 catalog unarchive --catalog "$CATALOG" <identity> --json
-```
-
-Archival moves the whole identity directory from `agents/<host>/<identity>` to
-`.st2/archive/<host>/<identity>` under the exclusive catalog-authoring lock, in one generation
-commit, as a same-filesystem rename — the archive root is a child of the catalog root, so no bytes
-are copied and no partial bundle can exist. `.st2` is control space at any depth, so an archived
-declaration is undiscoverable rather than filtered, and the whole-catalog transaction never projects
-it. A tombstone beside the moved directory keeps the identity traceable as one `archived` row in
-`st2 catalog graph --json`.
-
-Eligibility fails closed against the local host only, because another host's runtime records are not
-observable from here: the declaration must sit at its canonical path, be retired in either spelling,
-have no live or dead record for any declared task (the rule `st2 doctor` already applies to
-retirement), and be named as `supervisor` by no declaration that stays behind. `--identity` refuses
-the whole run if any named identity is ineligible; `--all-retired` reports the ineligible ones and
-archives the rest. `st2 catalog unarchive` is the exact reverse move.
-
-`st2 up` applies exactly this gate on its own once a retirement outlives `archive-after`, so these
-verbs are for the seats you do not want to wait out and for putting one back.
-
-The compact declaration shape is:
-
-```kdl
-agent "<identity>" {
-  host "<host>"
-  workspace "<workspace>"
-  resource "work" uri="github-issue://example/project/123" reason="release work item"
-  // Optional metadata:
-  // role "worker"
-  // supervisor "<supervisor-bus-id>"
-  // name "Release worker"
-  // description "Owns release preparation and verification."
-  argv "codex" "--dangerously-bypass-approvals-and-sandbox" "--dangerously-bypass-hook-trust" "<boot prompt>"
-  ding
-
-  render {
-    copy "assets/AGENTS.md" "AGENTS.md"
-    json-upsert ".codex/hooks.json" #"""
-{"hooks":{"SessionStart":[{"hooks":[{"type":"command","command":"$ST_HOOKS/codex-session-start.sh","timeout":5}]}]}}
-"""#
-    git-exclude "AGENTS.md" ".codex/hooks.json"
-  }
-}
-```
-
-For a zero-interruption migration, add `lifecycle "adopt-only"` to the compact
-agent or to an explicit `pty`/`exec` task. st2 adopts that task when its current
-generation is alive. If the generation is dead or absent, st2 reports the task
-as `held` and does not remove or launch that task. A compact `ding` is derived
-from the generated agent task: while that agent is held, st2 suppresses a
-missing DING and stops an exact generated DING proved live:
-
-```kdl
-agent "<identity>" {
-  host "<host>"
-  workspace "<workspace>"
-  lifecycle "adopt-only"
-  argv "codex" "<boot prompt>"
-}
-```
-
-This is a fence, not a restart policy. After inspecting or recovering the
-original generation, deliberately change the lifecycle back to `"service"` (or
-remove the field) to authorize ordinary absent launch and dead replacement.
-Whole-agent desired state remains an explicit, separate lifecycle instruction
-and takes precedence over task lifecycle. To keep an agent in the catalog while
-running none of its tasks:
-
-```sh
-st2 --catalog <catalog> agent desired-state <identity> suspended \
-  --reason "Waiting for capacity"
-st2 --catalog <catalog> agent desired-state <identity> running
-st2 --catalog <catalog> agent desired-state <identity> retired \
-  --reason "Mission complete"
-```
-
-The canonical KDL is `desired-state "suspended" reason="..."`. Running is
-canonically omitted. New suspended and retired states require a bounded reason;
-legacy `retired #true` remains readable. Suspension stops the agent and its
-derived DING without deleting its declaration, inbox, context, or Resources.
-Resume uses ordinary `service`, `adopt-only`, and `keep` behavior. Nix-owned
-declarations must be changed at their Nix source.
-
-`resource` binds an agent-local semantic name to an exact RFC 3986 absolute URI. The URI scheme
-selects an open, downstream-owned Resource profile; st2 preserves URI bytes without normalization.
-It neither registers schemes, owns profile schemas, nor resolves targets.
-Binding order is irrelevant and names must be unique within the agent:
-
-```kdl
-resource "work" uri="github-issue://example/project/123" reason="release work item"
-resource "source" uri="worktree://github.com/example/project/change" reason="primary checkout"
-resource "delivery" uri="ding://host/agent" reason="notification channel for this agent"
-```
-
-The envelope is `name` + `uri` + a required human-facing `reason`, plus an optional
-`inactive-reason` that preserves a retired binding without deleting it. It carries no
-access, readiness, or lifecycle policy, and URI possession conveys no authority. A Resource URI may
-be referenced by any number of agent declarations. Resource-only declaration edits do not stop,
-replace, or relaunch a live task. Resource profiles and resolvers remain opaque to st2; catalog
-readers use the public `agent-spec` crate to inspect the bindings, and `st2 resource ls|read`
-projects them for one agent.
-
-The positional agent value is the stable automation identity. Optional `name` and `description`
-fields are presentation only; they never route messages, select tasks, or rename durable state.
-Mutate a catalog-owned KDL declaration through the constrained commands:
-
-```sh
-st2 rename <stable-id> "Release worker"
-st2 describe <stable-id> "Owns release preparation and verification."
-st2 rename <stable-id> --clear
-st2 resource add <name> --uri <uri> --reason "<why this agent carries it>"
-st2 resource remove <name>
-st2 resource rename <old> <new>
-```
-
-These commands preserve unrelated KDL bytes and serialize local writers through the persistent
-shared `.st2/catalog-authoring.lock`. They refuse TOML, JSON, and
-explicitly `meta { managed-by "nix" }` targets. Nix generators must emit that marker before the
-compatible st2 binary is activated. In the trusted single-operator fleet, caller-supplied
-`ST_AGENT` limits an invocation to itself or declared descendants; it is a guardrail rather than
-authentication, and absence selects the operator path. The sibling `<agent-dir>/name` convention
-is hard-retired and ignored.
-
-`argv` launches its first value directly with the remaining values as arguments. It resolves a bare
-program such as `codex` through the task environment's `PATH`, preserves argument boundaries, and
-does not introduce a shell. Use `command #"..."#` instead when the task intentionally needs shell
-syntax such as pipelines, redirects, or variable expansion; `command` continues to run under
-`sh -c`. A runnable task must declare exactly one of `argv` or `command`.
-
-### Scheduled work is coming soon, not implemented
-
-st2 does not parse or run scheduled entries today. The intended direction starts with a declarative
-DING targeted at the containing agent; scheduled PTY or exec work may be considered later. This is a
-non-functional preview, and `st2 validate` correctly rejects it today:
-
-```kdl
-agent "<identity>" {
-  // Current implemented fields and tasks go here.
-
-  // FUTURE ONLY — reserved and rejected by the current contract.
-  schedule "local-health" {
-    every "2h"
-    ding "Run the local health check."
-  }
-}
-```
-
-st2 provides `CATALOG`, flat native `ST_ROOT`, local `PTY_ROOT`, `ST_AGENT`, and `ST_HOOKS` to the
-task. The complete st2-managed overlay is also persisted in PTY metadata, so a manual `pty restart`
-retains those values. Declarations should not contain machine-specific install paths.
-
-## Validate and materialize
-
-Gate the declaration before starting anything:
-
-```sh
-st2 hooks verify
-st2 validate --catalog "$CATALOG" --strict
-st2 up --catalog "$CATALOG" --host <host> --materialize-only
-```
-
-Validation always checks the whole synced catalog structurally. External workspace and task-path
-presence is checked only for the selected run host, which defaults to the local short hostname; use
-`--host <host>` to validate another machine's local paths. Supervisors may be declared as either a
-bare identity or the fully-qualified `<host>.<identity>` bus id.
-
-Materialization simulates all content operations before writing. It refuses any real change to a
-Git-tracked target, including a mode-only change; byte-identical content with the declared mode is
-accepted. Inspect the declared targets and keep generated overlays untracked. Detection invokes
-`git` and fails closed if the executable is unavailable or a workspace that appears to be a worktree
-cannot be inspected.
-
-Each content directive accepts `executable=#true`. st2 applies exact mode `0755` when the property is
-true and exact mode `0644` when it is absent or false. Materialization repairs a wrong existing mode
-even when the file bytes already match. A `copy` source mode does not affect the destination mode.
-An operation whose bytes and mode already match is not reported as materialized.
-
-Inline content uses the existing `file` directive. st2 writes the decoded KDL string without adding
-or removing a newline. A blank line before a multiline string's closing delimiter encodes one final
-newline:
-
-```kdl
-file ".st2/bin/probe" executable=#true {
-  content #"""
-#!/bin/sh
-printf 'ready\n'
-
-"""#
-}
-```
-
-Use `ensure-line` when a workspace-owned text file must import a catalog-owned contract:
-
-```kdl
-copy "_templates/CONTRACT.md" ".st2/CONTRACT.md"
-ensure-line "CLAUDE.md" "@.st2/CONTRACT.md"
-ensure-line "AGENTS.md" "@.st2/CONTRACT.md"
-```
-
-Each harness loads the import from its native contract file. A later boot-prompt rewrite cannot
-silently remove the contract-loading instruction. On 2026-09-01, Alex stated that Codex supports
-`@` imports in `AGENTS.md`. This Codex behavior is undocumented and was not source-verified for this
-change.
-
-`ensure-line` searches a UTF-8 file for one exact full line. An existing match causes no write.
-If the line is absent, st2 preserves all existing bytes, adds a separator newline when necessary,
-and appends the declared line with a final newline. st2 creates a missing target in a non-Git
-workspace or when Git does not track that path.
-
-For a Git-tracked target, `ensure-line` is a verifier. st2 accepts an exact existing line but refuses
-to add a missing line. The refusal occurs before any render operation writes to the workspace. The
-repository owner must add and commit the line outside st2. This rule prevents materialization from
-leaving a customer repository dirty or changing a repository that assistants can only read.
-
-`git-exclude` is advisory. `copy`, `file`, `json-upsert`, and `ensure-line` are boot-gating.
-
-## Run
-
-On headless Linux, install the systemd user service:
-
-```sh
-st2 service install --catalog "$CATALOG" --host <host>
-st2 service status
-```
-
-Each task runs in its own transient scope, so restarting the supervisor does not kill live agents.
-
-On macOS, use a manual one-shot reconcile:
-
-```sh
-st2 up --catalog "$CATALOG" --host <host> --once
-```
-
-There is intentionally no resident macOS service path.
-
-For a shortest-path change to one exact task, render only its owning agent and reconcile only that
-task in a bounded pass:
-
-```sh
-st2 up --catalog "$CATALOG" --host <host> --once --task <host.agent.task>
-```
-
-Unknown, ambiguous, and wrong-host task selectors refuse before workspace writes or PTY inspection.
-A selected generated DING that is dead or absent is reported as `held`, because starting its
-canonical agent would broaden the exact-task operation. Explicit sibling tasks remain independently
-selectable.
-
-`st2 doctor` accepts the absence of a live host lock as the normal manual/`--once` mode. For a
-resident `st2 up` deployment, use `st2 doctor --require-supervisor` to make a missing loop fail the
-health check. A stale lock left by a dead supervisor is always a failure. The underlying
-non-interactive `pty list --json` runtime probe is bounded; a wedged client becomes an explicit
-doctor failure instead of hanging the health check. Its short outer deadline is containment for a
-wedged runtime, not a fleet-scalability mechanism.
-
-For a foreground supervisor on any host:
-
-```sh
-st2 up --catalog "$CATALOG" --host <host>
-```
-
-### Typed task inventory (diagnostic only)
-
-Use the typed inventory instead of parsing `doctor` prose:
-
-```sh
-st2 tasks --catalog "$CATALOG" --host <host> --json
-```
-
-The `st2.task-inventory.v3` envelope joins the selected host's desired PTY and exec tasks to
-read-only runtime evidence. Each row keeps the declared `residencyPolicy` separate from nullable
-host-local `runtimeResidency`. A complete observation exits zero. Catalog parse errors, declaration
-drift during observation, duplicate runtime IDs, malformed residency records, timeouts, malformed
-output, PID reuse, and otherwise unprovable generations emit `complete: false` and exit non-zero.
-Missing runtime rows become `absent` only when the corresponding backend observation is complete;
-uncertainty remains `indeterminate`.
-
-Every runtime has a tagged `resourceTarget`. A live Linux process reports
-`{"type":"linuxCgroupV2","path":"/..."}` from its exact unified
-`/proc/<pid>/cgroup` membership; a live Darwin process reports
-`{"type":"darwinProcessTree","rootPid":...}` as a best-effort tree root. All
-other cases report `{"type":"unavailable","reason":"..."}` from a bounded
-reason set. These are per-observation locators, not identity: consumers keep
-using `runtimeId` as the stable task key and rediscover the target on each
-sample.
-
-A PTY root positively absent at admission is not passed to `pty` and remains absent; an absent exec
-state root likewise remains absent. If an admitted PTY root is concurrently removed, the result is
-incomplete because its filesystem identity changed, but the external `pty list` implementation may
-recreate its registry before st2 can detect the race. Observation never rewrites an existing exec PID
-record. It also does not serialize catalog or runtime writers, reconcile tasks, or authorize a
-control-plane cutover. Consumers that require a zero-write boundary under concurrent root deletion
-or a transactional declaration boundary need a separate protocol.
-
-### Staged control-plane replacement gate
-
-`st2 up` is a replaceable control plane, not the lifetime owner of an agent. Stopping it normally
-or killing it must leave every agent running. `st2 down` and declaration retirement are separate,
-explicit lifecycle actions and must never be used merely to replace the control plane.
-
-Every staged recovery or binary cutover must retain a pre-stop receipt of each agent's stable task
-identity, PID, and process-creation identity. Install the verified replacement binary atomically
-while those tasks continue running, restart the control plane, and do not accept the host until its
-first reconcile proves all of the following:
-
-- every pre-existing agent is still usable with the same PID and creation identity;
-- the replacement reports those agents as adopted and does not launch or duplicate them;
-- only genuinely missing declared work is launched;
-- explicit teardown remains the only path that stops an agent.
-
-The executable gate drives the real st2 binary and both PTY and exec backends through normal stop,
-forced kill, atomic binary replacement, adoption, a live-task heartbeat, and a duplicate-boot
-receipt:
-
-```sh
-cargo test --test integration --all-features nomad_survival::
-```
-
-## Messages, DING, status, and context
-
-Inside a managed task, `CATALOG`, `ST_ROOT`, and `ST_AGENT` are already set:
-
-```sh
-st2 status "$ST_AGENT" --set available
-st2 message send <recipient> --subject "work" -m "Please handle the scoped task."
-st2 message ls
-st2 message read <filename>
-st2 message reply <filename> -m "Handled."
-st2 message archive <filename>
-st2 agents --json --enrich
-st2 agents --identity "$ST_AGENT" --json
-st2 context read --full
-```
-
-The roster includes suspended and retired declarations instead of silently conflating desired
-lifecycle with runtime presence. Both JSON shapes keep stable `identity` separate from optional
-`name` and `description`, and contain the compatibility `retired` projection, `desiredState`,
-`desiredStateReason`, plus the declaration's ordered `resources` descriptors. `--enrich`
-additionally supplies `lastActivity` and `inbox`. Human output prints the same presentation fields
-as separate columns and appends the non-running state and rationale.
-`--identity <host>.<identity>` selects exactly one qualified Agent Spec or fails,
-so external harness hooks can read its current name and description without parsing KDL or relying
-on a duplicate state file.
-
-For a catalog-backed agent, every native bus operation resolves the same agent directory used by
-the roster: presence is `<agent-dir>/status`, while unread messages, archive receipts, and context
-live under `<agent-dir>/resources/`. The flat `<root>/<identity>` layout remains only as the
-intentional catalog-less fallback used by isolated folder evals. In a catalog-backed root,
-`st2 message ls` rejects an absent identity; recovery inspection of a deliberately orphaned flat
-box must be explicit with `st2 message ls <identity> --orphan` (and optionally `--archive`).
-
-Services use a separate declared request surface; they do not borrow an Agent
-Spec identity. Declare the endpoint without creating a task:
-
-```kdl
-// <catalog>/principals/host-a/example-ci/principal.kdl
-principal "example-ci" host="host-a"
-```
-
-Then publish once, let the addressed agent reply from its normal inbox, and
-observe the typed result. Bodies are JSON and `--tag` is a repeatable
-`key=value` map:
-
-```sh
-st2 request send host-a.repair-agent \
-  --as host-a.example-ci \
-  --idempotency-key 'escalate:repo#7:abc' \
-  --tag kind=example-ci.escalation \
-  -m '{"candidate":"abc"}' --json
-
-st2 request read <request-filename> --json
-
-st2 request reply <request-filename> \
-  --tag outcome=needs-human \
-  -m '{"outcome":"needs-human"}' --json
-
-st2 request status --as host-a.example-ci \
-  --idempotency-key 'escalate:repo#7:abc' --json
-```
-
-The key atomically reserves one message filename and exact envelope before
-publication. Exact retries return that filename with `deduplicated: true`; a
-different request under the same key fails. Replies route only to the declared
-principal's canonical `resources/inbox`, never a flat orphan mailbox.
-
-Adopters should cut directly to the native layout. Before launching a migrated identity, install and
-verify hooks, validate and materialize its hand-authored declaration, stop any predecessor transport,
-and decide how any unread predecessor backlog will be archived or forwarded. Never run predecessor
-and native DING owners concurrently for the same identity.
-
-A pi agent does not use DING. Its messages are delivered natively into the live session by the
-channel extension st2 injects, which calls pi's own message API and reads pi's own idle proof, so
-no screen is inspected on that path. Declare it with a typed `pi {}` driver or with
-`deliver "pi-channel"`. If the declaration also carries `ding`, native delivery wins and st2 omits
-the sidecar.
-
-Native DING watches the recipient inbox and delivers a normalized notice:
-
-```text
-[DING] new st2 message: [id:<rand6>] <subject> (from <sender>); check your inbox
-```
-
-Consumers must key on the `[DING]` prefix and stable id, not descriptive words. Every maintained
-harness that uses DING uses the same transport: normalize untrusted fields into bounded,
-single-line printable text, positively identify an empty current Codex or Claude composer, and send one bracketed-paste
-sequence without Return. The sidecar then observes for a short bounded window and sends a separate
-bare Return only after two immediately adjacent inspections show the exact notice in a positively
-idle composer. A human draft, active turn, modal, changed composer, unreadable screen, command
-timeout, or unknown renderer defers submission. Once a paste command starts, the sidecar retains
-ownership and retries by inspection only, so a timeout cannot duplicate the paste. This measured
-screen heuristic is fail-closed for the maintained renderer versions but is not an evented TUI
-contract; renderer changes can defer delivery and remain an explicit design gap.
-
-Agents must declare `busy` before actively executing work and return to `available` only when
-yielding or ready for new work, but `busy` never suppresses DING. Fresh `dnd` is the only delivery
-hold. Each status record keeps the state on its first line. Version 1 writers add `v1 <unix-ms>` on
-the second line. New readers use that origin timestamp and accept a legacy bare state. Old readers
-keep using the first line and file mtime. A live session owner refreshes non-DND presence every five
-minutes. This changes the replicated bytes and stays below the 15-minute stale limit. A legacy
-`dnd` upgrades once with its existing mtime, then remains unchanged. A malformed versioned record or
-a timestamp more than 60 seconds in the future reads as `unknown` without an mtime fallback. Version
-1 status contributes its origin timestamp to `lastActivity`. New arrivals remain FIFO.
-Same-filename archive receipts shadow and clean
-restored inbox duplicates. Failed or uncertain PTY operations retain the notice for safe retry. Unsafe
-delivery retries use a bounded backoff, so an active composer cannot make the sidecar spawn a fresh
-PTY probe on every inbox poll. On start
-or restart, the sidecar first adopts an exact staged recovery/backlog notice when present, then sends
-one generic check-inbox recovery DING if unread work remains; it does not replay every backlog
-message.
-
-Both DING and the catalog supervisor use filesystem events only as an early-wake optimization.
-Create, modify, rename, and remove events wake them; read/open access events do not. Their own inbox
-and catalog reads therefore cannot self-trigger a Linux inotify loop, and the bounded timer remains
-the correctness fallback.
-
-## Cleanup
-
-Explicit teardown is the only operation that ends declared tasks:
-
-```sh
-st2 down --catalog "$CATALOG" --host <host>
-```
-
-On Linux, remove the supervisor service after teardown when it is no longer wanted:
-
-```sh
-st2 service uninstall
-```
-
-## Command surface
-
-```text
-ls, up, down, validate, doctor
-message, ding, agents, status, context, resource, rename, describe
-env, pty, shell, pretrust
-hooks, service, claude-channel, eval
-agent digest, agent publish
-catalog bootstrap, catalog snapshot, catalog apply, catalog archive, catalog unarchive
-completions
-```
-
-`st2 completions <shell>` emits completions from the live command tree. No generated completion or
-manpage tree is committed.
-
-## Clean-room verification
-
-The test suite builds a temporary `PATH` containing only the current `st2` binary, required Git,
-and `pty`, `codex`, and `claude` shims. It installs and verifies a scratch hook receipt, instantiates
-both maintained hand-authored KDL examples in fresh Git workspaces, validates and materializes them
-twice, and verifies the help/doctor/native authoring surface without a predecessor transport binary:
-
-```sh
-cargo test --test integration --all-features native_only::
-```
-
-Run the complete local gate with:
-
-```sh
-cargo clippy --all-targets --all-features -- -D warnings
-cargo test --all-targets --all-features
-```
-
-The linker can exhaust a small temporary filesystem during a complete gate. A space or quota error
-is an environment failure, not a compile failure. Set `CARGO_TARGET_DIR` to a filesystem with enough
-space, reduce parallel jobs or debug information if necessary, and rerun the same gate. Use
-`cargo clean --target-dir <path>` to remove the temporary build artifacts after the run.
-
-## Eval contract
-
-The sole canonical agent contract is
-[`AGENT-SPEC.md`](https://github.com/compoundingtech/evals/blob/main/AGENT-SPEC.md) in the evals
-repository. Eval corpus definitions, execution/readiness evidence, authorization, and results belong
-to that repository; st2 does not duplicate or pin its ledgers here.
-
-An eval that exercises production Agent Specs opts in explicitly:
-
-```kdl
-eval {
-  copy "./fixture"
-  run "publish-canonical-team" { command "..." }
-  canonical-agents
-  message { from "requester"; to "evalhost.supervisor"; content "./task.md" }
-  max-timeout "300s"
-  judges { /* held-out checks */ }
-}
-```
-
-`copy` and deterministic `run` steps populate the hermetic temporary catalog first.
-`canonical-agents` then recursively discovers the catalog and projects declarations resolved to the
-eval host. Explicit `identity` and `host` fields remain authoritative independent of organizational
-placement; each declaration parent remains its native state/resource anchor. The directive is
-mutually exclusive with compact `team` / `agent` declarations, so the local Agent Spec vector is the
-sole authority for launch, kickoff routing, supervision, logs, and teardown. Strict catalog
-validation, fleet-unique nonempty task runtime IDs, and warning-free local materialization all finish
-before an agent task starts; backend launch errors are fatal. Remote-host declarations remain inert.
-Native inbox/archive paths are frozen from the admitted local vector, so later catalog mutation
-cannot redirect eval traffic. A multi-agent team completes only after the existing worker-report ordering.
-For a singleton, the requester inbox is snapshotted before kickoff; only a newly appearing
-interviewer reply at-or-after the exact kickoff receipt completes it. Canonical completion gates the
-verdict. Without the directive, Agent Spec-shaped files inside a fixture remain inert and compact
-evals retain their flat bus and completion semantics.
-
-`st2 agent publish --catalog ROOT (--spec FILE | --bundle DIR) --input-sha256 HEX
-(--expect-absent | --expect-sha256 HEX) [--managed-by MARKER]` is the single-agent declaration
-writer. Replacing an incumbent that carries `meta { managed-by "nix" }` requires
-`--managed-by nix`, because that publication rewrites bytes the Nix projection owns; an assertion
-is admitted only when it names exactly the marker the incumbent carries. Creating a declaration
-and republishing byte-identical bytes need no assertion.
-`st2 catalog apply --catalog ROOT
-(--prepared DIR --input-sha256 INPUT_HEX --expect-sha256 ROOT_HEX [--raw-preimage] | --resume)` is the complete
-declaration-plane writer. Each admits the complete prospective catalog under a
-compare-and-swap lock before making one atomic change.
-`st2 catalog digest --catalog ROOT --prepared DIR` computes the exact desired
-projection digest consumed by apply. Raw-preimage repair uses it for the fully
-validated successor while binding the opaque incumbent through the separate
-raw-domain digest. Ordinary valid-catalog workflows reuse `afterRootSha256`
-from the required policy-inspection diff instead.
-`st2 catalog bootstrap --catalog ROOT --prepared DIR --input-sha256 ROOT_HEX`
-is the create-only writer for an absent catalog. An exact completed replay is
-`unchanged`; any different or incomplete existing target fails closed.

 With Node 24 and Corepack, run `corepack enable` and `pnpm install --frozen-lockfile` from the repository root. Corepack provisions the root's pnpm 12.15.0; the single install covers the client, views and iOS packages. Alternatively, `nix develop .#web` supplies pnpm 12.15.0, Node 24.20, Bun 1.4.2 and Buck2. Then from this directory run `pnpm typecheck`, `pnpm test`, and `pnpm exec expo prebuild --platform ios --clean --no-install`. Install CocoaPods, run `pnpm run pods` (the wrapper sets `LANG` and `LC_ALL` to `en_US.UTF-8`), and open the generated `ios/fractal.xcworkspace` in Xcode. For daily development, build the Debug scheme for an iOS Simulator and run `pnpm start` for Metro. Keep normal simulator code signing enabled: building with `CODE_SIGNING_ALLOWED=NO` leaves the app without a usable Keychain, so device pairing fails. A physical device is optional for this development proof.

+
+Typed authoring and deterministic KDL v2 encoding for Fractal agents, missions and schedules. This is a declaration package, not the daemon HTTP client (`@fractal/client`). It has no runtime dependencies.
+
+```ts
+import { encodeKdl } from '@fractal/declarations'
+import type { Agent, Mission, Schedule } from '@fractal/declarations'
+
+const editor = {
+  id: 'docs/editor',
+  workspace: '.',
+  launch: { command: 'true' },
+} as const satisfies Agent
+
+const writer = {
+  id: 'docs/writer',
+  workspace: '.',
+  launch: { argv: ['review-docs', '--daily'] },
+  under: { agent: editor, reason: 'The editor reviews the writer’s work.' },
+} as const satisfies Agent
+
+const review = {
+  id: 'docs/daily-review',
+  state: 'ready',
+  reportTo: editor,
+  goals: ['Review the documentation each day.'],
+  completion: 'all-steps-exhausted',
+  steps: [{
+    id: 'review',
+    assignedTo: writer,
+    goals: ['Review the documentation and report corrections.'],
+  }],
+} as const satisfies Mission
+
+const daily = {
+  id: 'docs/daily-review',
+  host: 'local',
+  every: '1d',
+  anchor: '2026-01-01T09:00:00Z',
+  catchUp: 'latest',
+  work: {
+    mission: review,
+    revision: 'b283ff12e887f06fbeb2da3094b10f8fd2b9b7840f7af8031445b124829f25f7',
+    workspace: '.',
+  },
+} as const satisfies Schedule
+
+const kdl = encodeKdl({ agents: [editor, writer], missions: [review], schedules: [daily] })
+```
+
+## Contract
+
+- IDs are bare declaration IDs, such as `docs/editor` and `docs/daily-review`. An `AgentId` must contain `.` or `/`, such as `remote.editor` or `docs/editor`: the parser preserves exactly those identities. Simple agent IDs such as `editor` are host-folded by the parser and are deliberately unsupported, because this SDK does not know or guess the default host.
+- Agent references accept an `Agent` object or a qualified string such as `agent/docs/editor` or `agent/remote.editor`; the same ID rule applies to declarations, `under`, mission `reportTo` and step `assignedTo`. The encoder throws an `Error` before returning KDL if an untyped caller supplies a host-folded agent ID/reference. Schedule work accepts a `Mission` object or its **bare** ID string, plus a separate explicit revision. Mission IDs are never host-folded, so simple mission IDs remain supported. Object references encode their ID; they do not implicitly emit the referenced declaration or compute revisions.
+- Launch is exactly one of `command: string` or a nonempty readonly `argv` tuple. Use `as const` to preserve tuple inference.
+- Mission states are `draft`, `ready` and `retired`; completion is `all-steps-exhausted`. Schedule catch-up is a discriminated union: `all` requires `maxCatchUp`, while `latest` and `skip` forbid it. The bound must be a positive u32, as checked by daemon validation.
+- Mission goals are readonly tuples of 1–3 strings; step goals are readonly tuples of 0–3 strings. A mission's step list has no parser-imposed minimum or maximum, so an empty step list is supported.
+- Collections are readonly and individually optional at the document root, but at least one collection must be nonempty, matching the publication parser. Input order is preserved within collections, goals and steps. Top-level kinds emit agents, missions, then schedules.
+- Required fields cover agent workspace and launch; mission state, report recipient, goals, completion and steps; step assignee and goals; interval schedule host, every, anchor and work; and work mission, revision and workspace. Optional `under` has one agent and reason. Some are stricter than parser defaults. Singleton fields serialize once; collection fields serialize their elements. The encoder emits only one completion condition, one agent launch and one interval timing form; competing completion conditions, harness launches and calendar/one-time schedules are outside this SDK.
+- Scalar and cross-declaration validation remains with the daemon: ID/name/reference syntax and lengths, duplicate IDs (including step IDs), reference resolution and ownership, registered variable interpolation, `under` reason length (1–500 bytes), interval duration and UTC anchor syntax, positive-u32 catch-up bounds, exact 64-hex mission revisions, nonblank schedule workspace, and the 16 MiB document limit. Types do not validate numeric ranges or string contents; validate encoded KDL before publication.
+- Output starts with `version 2`, uses two-space indentation and newline-delimited children, separates top-level blocks with a blank line and ends with a newline. Strings escape quotes, backslashes, newlines, carriage returns and tabs; other controls use KDL v2 braced Unicode escapes, including `\u{8}` and `\u{c}` for backspace and formfeed.
+- This package exposes only the supported declaration vocabulary, not runtime state, arbitrary KDL children, hooks, step dependencies or cron expressions. It does not publish declarations, start runs or replace daemon validation. Validate the emitted KDL with Fractal before publication.
+
+## Generated source and checks
+
+`index.ts` is generated by the Rust client code generator. Do not edit it by hand. From the repository root:
+
+```sh
+cargo run -p fractal-client-codegen
+cargo run -p fractal-client-codegen -- --check
+pnpm --filter @fractal/declarations test
+pnpm --filter @fractal/declarations typecheck
+```
+
+The Node contract suite transpiles the generated TypeScript with the workspace’s TypeScript compiler. Its exact golden fixture, `fixtures/daily-review.kdl`, represents the `st validate` fixture `crates/fractal/tests/fixtures/validate-revisions.kdl` declarations with canonical multiline completion formatting. The suite also covers references, quoting, argv, collection ordering, readonly inputs and supported enum variants. `type-tests.ts` uses positive examples and compile-time negative assertions without suppressing diagnostics. Both package checks run in `scripts/ci-typescript-client`.

+//! How far a message got on its recipient's host, read through the seat-freshness relay (db
+//! break-up step 4b).
+//!
+//! A host that advertises `message_offsets` keeps its seats' delivery, read and close of graph
+//! mail as local marks and writes no lifecycle claims for them, and every host keeps a stream
+//! item's lifecycle in its own shard. Another member that needs that state, such as
+//! `conversations status` or doctor's mail checks, asks the host and never guesses. A host that
+//! does not answer within the deadline reads as unknown, never as sent.
+//!
+//! Answers are kept a few seconds, so repeated reads of one message ask the host once, and so is
+//! a host's silence, so doctor's checks, one after another, wait for a silent host once. One read
+//! asks at most [`MAX_HOSTS`] hosts, all at once, and at most [`MAX_MESSAGES_PER_HOST`] messages
+//! of each, so a slow host costs one deadline and a large backlog a bounded number of requests.
+//!
+//! A message view or list asks the same way ([`read_views`]), but a UI never waits long: it waits
+//! [`VIEW_DEADLINE`], and a host that did not answer is not asked again by views for
+//! [`VIEW_SILENT_FOR`]. Its messages then read as this member's own records, with
+//! `status_from` saying the host's answer is unknown.

-//! Move retired, runtime-free identities out of the live declaration plane.
-//!
-//! `retired` is runtime teardown only: the declaration and its `resources/` stay byte-identical and
-//! reversible. Archival is the pressure valve that keeps the live catalog bounded. An archived
-//! identity's whole directory is moved under the catalog control plane, where `.st2` is already
-//! excluded at any depth by discovery, validation, and the whole-catalog transaction — so an
-//! archived spec is structurally undiscoverable rather than merely filtered. A tombstone beside the
-//! moved directory keeps the identity traceable in `st2 catalog graph --json`, and
-//! `st2 catalog unarchive` is the exact reverse move.
-//!
-//! Both moves run under the catalog's exclusive authoring lock and inside one generation commit,
-//! and both are same-filesystem renames by construction: the archive root is a child of the catalog
-//! root, so there is no copy engine and no partially copied bundle to reason about.

-//! Direct OMP actors: live-catalog identity directories owned by one stable PTY session.

-//! A direct OMP launch has no declaration. Its entrypoint derives

-//! The `exec` backend (M1b) — terminal-free process supervision (R09).
-//!
-//! `pty` tasks go to the `pty` CLI (which allocates a pseudo-terminal — an agent harness). `exec`
-//! tasks (the ding, daemons, a stage's script) must NOT allocate a terminal, so st2 supervises them
-//! directly: shell source through `sh -c`, or a structured argv with no shell. The process is spawned
-//! in its own session (`setsid` — no controlling tty, and decoupled from st2 so it survives st2 exit,
-//! Nomad-style), stdout/stderr go to a log file, and the pid is recorded in a machine-local
-//! runner-state dir. Liveness is `kill(pid, 0)`; st2 best-effort reaps its own exited children so a
-//! zombie never reads as alive. The same `setsid` session doubles as the teardown unit: an explicit
-//! kill targets the whole process GROUP, so a task's children die with it (see
-//! [`ExecBackend::kill`]) — a plain stop of st2 never touches it.
-//!
-//! State is machine-local (pids don't sync across hosts) and keyed by host, so a restarted st2 on the
-//! same host adopts the exec processes it left running.

-//! The restart cap (M1b) — st2's crash-loop guard, driven by the job's declared `restart{}` policy
-//! (`docs/vrs/requirements.md` R31), so every conformant runner behaves identically on a flapping
-//! task.
-//!
-//! st2 owns liveness (it respawns a dead task on the next reconcile), so it also owns the restart
-//! decision. Per task it enforces `delay` spacing, then applies `mode`: `delay` **rate-limits** using
-//! a sliding `interval` window (keep restarting once the window clears), while `fail` **parks** the
-//! task (give up + surface it) once its failure budget is spent.
-//!
-//! Those two need different counters, because a rate window cannot express a budget. When a task
-//! stays up longer than roughly `interval / attempts` before dying again, earlier launches can age
-//! out before `attempts` coexist in the window, so a window-scoped `fail` budget never exhausts.
-//! The `fail` counter instead spans launches until the task *stays up* for a full `interval`;
-//! reconcile cadence cannot outrun it. That makes [`FlappingCap::end_pass`] load-bearing: it is how
-//! the cap learns a task survived.
-//!
-//! The clock is injected (`now: Instant`) so every branch is unit-testable without sleeping.

-//! Isolated task spawn (R21b) — the permanent fleet-fragility fix.
-//!
-//! st2 already survives its own *process* death (`setsid`, see [`crate::exec_backend`] and
-//! `tests/nomad_survival.rs`). But `setsid` changes a process's **session**, not its **cgroup**.
-//! systemd tears a unit down by cgroup, so restarting a supervisor unit would kill every task still
-//! in that cgroup.
-//!
-//! The fix: spawn each task into its own OS supervision domain, independent of BOTH the spawner and
-//! the transport daemon — one goal, per-OS mechanism.
-//!
-//! - **Linux with systemd 236+**: `systemd-run --user --scope --collect --quiet --unit=<unit>`
-//!   `-- <task>`, with `--expand-environment=no` on v254+. Legacy scopes directly exec argv. The task runs in its own transient scope = its own cgroup,
-//!   registered with the user manager as a **sibling** of the transport unit (a scope created inside
-//!   a service lands at `app.slice/<unit>`, not nested under the service). A cascade kill of the
-//!   transport unit's cgroup cannot reach a sibling. `--scope` (not `--service`) keeps st2 the logical
-//!   supervisor — systemd provides only the cgroup; adoption/teardown/restart stay st2's. `--collect`
-//!   GCs the scope once it empties.
-//! - **macOS / unsupported Linux**: `setsid` + reparent to init/launchd is the fallback. Here [`wrap`]
-//!   is a no-op pass-through; the caller's existing `setsid` (exec) or the `pty` daemon (pty) provides
-//!   detachment. If isolation was wanted but the systemd user manager or the exact-argv capability
-//!   is unavailable, we degrade to that pass-through and log a loud WARN — never a silent
-//!   "isolated" claim.
-//!
-//! Teardown is unchanged: the scope is for **survival only**. `pty kill` / the exec process-group kill
-//! still tear tasks down; the scope just prevents the transport from taking them as collateral.

-//! The parked set's on-disk projection, and the operator's unpark request channel.
-//!
-//! [`FlappingCap`](crate::flapping::FlappingCap) is the source of truth for which tasks are parked,
-//! and it lives in the supervisor's memory. Everything else — `st2 tasks` above all — is a separate,
-//! read-only process, which is why a parked task used to show `desired: running`, not running, and
-//! `error: null`: the fault existed, but only inside a process nobody was reading. This module is how
-//! that in-memory truth becomes legible without becoming a second source of it.
-//!
-//! Two directions, one writer each. Conflating them is the tempting mistake:
-//!
-//! * The **projection** (`parked/`) is written by the supervisor and read by observers in its scope.
-//!   A missing or absent marker means *not parked*. Nothing else may write here.
-//! * The **request** (`unpark/`) is written by `st2 unpark` and consumed by the supervisor. A missing
-//!   request means *nobody asked*.
-//!
-//! Were the projection also the request — "no marker, therefore unpark" — then a wiped state dir, a
-//! failed write, or a supervisor and CLI disagreeing about `XDG_STATE_HOME` would all silently mean
-//! *release every parked task in that supervisor scope*. Each direction instead fails towards
-//! inaction. Both directions use the same scope: the canonical catalog folder plus host. Hashing that
-//! tuple keeps same-host supervisors from deleting each other's markers or consuming each other's
-//! requests, including when their task IDs collide.
-//!
-//! A marker is stamped with the generation of the supervisor that wrote it, and a marker whose
-//! supervisor is gone reads as **not parked**. That is not leniency: R31 scopes parking to one
-//! supervisor run, so no run means no park. It also keeps `st2 tasks` quiet and zero-exit for a scope
-//! whose supervisor is not running. The generation is `(pid, start-time)` rather than a bare pid,
-//! because a recycled pid would otherwise resurrect a park from a supervisor that died days ago.

-//! Delivery rides the event-stream machinery through a crate-internal admission for the built-in
-//! reserved `resync` stream that exists on every running agent without declaration. Public event
-//! ingress remains declaration-gated. Watching is
-//! deny-by-default: one non-recursive watch per distinct parent directory of the resolved

+//! store. The test writes to it. It prints one JSON receipt: the drain of any backlog the copy
+//! held, then the projection pass for each planning claim, with its writer-lend stages and the
+//! claims each stage rebuilt. `ST3_PLANNING_PROBE_SESSION` names the probe session, so several

+### Pins identity
+
+Each person has one Pins arrangement at
+`arrangement/person/NAME/00000000-0000-7000-8000-000000000002`.
+The generated clients expose `PINS_ARRANGEMENT_UUID` (Swift:
+`st3PinsArrangementUuid`) from `constants` in `operations.json`.
+Clients select only this identity, regardless of its display name; there is no
+name-based fallback and no copy from Sidebar folders or placements.
+
+The first pin creates this arrangement named "Pins" with `version: 2`.
+Pins use the existing ordered memberships contract: `arrangement.membership.edit`
+places a stable member subject at `{bucket: null, key}` or removes that member.
+Clients read and follow `ordered-memberships`, including pagination and whole-container
+invalidation. They never write v1 placements or mutate Sidebar folders to pin a subject.
+Membership admission, permitted subject families, lifecycle visibility, ordering,
+limits and canonical conflict resolution are the existing version-2 rules.
+
+Before creating Pins, coordinate the version-2-aware reader rollout described in
+the [client contract](../st3/client-v0/README.md#ordered-memberships-and-new-version-2-layouts).
+A create refused with `arrangement-exists` adopts the reserved live v2 arrangement.
+A v1 body at that identity is incompatible, not silently migrated. Retirement is
+permanent: `arrangement-retired` reports restoration unavailable and never selects
+another identity. Hidden or retired members retain the server's membership winner;

Evidence only advances, and only to a phase the harness can actually observe: Codex proves transport acceptance and consumption, OpenCode transport acceptance and durable read-back, and a record claiming any other phase is refused. Codex binds acceptance to the exact returned turn; either the correlated completed user-message item or that exact turn's successful completion proves consumption, including supported releases that omit the item notification. Only an authoritative negative receipt re-authorizes a retry. Settlement stays with the recipient: an entry is released only on a phase its profile releases, and is otherwise reconciled away when the message leaves the unread set. A consumed but still unread entry remains in ledger history without owning the FIFO head, so the next unread unsettled filename may proceed exactly once; projected graph delivery remains merely sent until that exact native filename is consumed. A foreign, malformed, or self-inconsistent record quarantines delivery without rewriting it, and the persisted ledger is owner-only with no temp residue. A delivery attempt an earlier release left behind is carried forward rather than re-sent: the pre-ledger `delivery-state.json` record is translated exactly once, when no ledger file exists, into an asserted phase that holds the delivery and authorizes no transport until this build observes evidence of its own. | `crates/fractal-drivers/src/delivery_ledger.rs::tests::begin_persists_attempted_before_transport`; `crates/fractal-drivers/src/delivery_ledger.rs::tests::positive_evidence_never_downgrades`; `crates/fractal-drivers/src/delivery_ledger.rs::tests::an_accepted_codex_turn_is_monotone_idempotent_and_conflict_fenced`; `crates/fractal-drivers/src/delivery_ledger.rs::tests::profiles_accept_only_evidence_their_harness_can_produce`; `crates/fractal-drivers/src/delivery_ledger.rs::tests::negative_receipt_is_the_only_retry_authority`; `crates/fractal-drivers/src/delivery_ledger.rs::tests::opencode_persistence_holds_until_the_correlated_turn_starts`; `crates/fractal-drivers/src/delivery_ledger.rs::tests::foreign_or_malformed_state_quarantines_without_rewriting`; `crates/fractal-drivers/src/delivery_ledger.rs::tests::every_entry_must_validate_its_own_correlation`; `crates/fractal-drivers/src/delivery_ledger.rs::tests::the_persisted_ledger_is_owner_only_and_leaves_no_temp_residue`; `crates/fractal-drivers/src/delivery_ledger.rs::tests::an_asserted_phase_suppresses_a_duplicate_and_authorizes_no_transport`; `crates/fractal-drivers/src/codex_app_server/tests.rs::a_consumed_unarchived_head_releases_the_next_fifo_message_exactly_once`; `crates/fractal-drivers/src/codex_app_server/tests.rs::a_successful_exact_turn_completion_settles_when_codex_omits_the_item_receipt`; `crates/fractal/src/main_tests.rs::graph_delivery_waits_for_the_exact_consumed_native_file`; `crates/fractal-drivers/src/migrations/delivery_state/mod.rs::tests::a_carried_forward_attempt_is_an_assertion_that_authorizes_no_transport`; `crates/fractal-drivers/src/migrations/delivery_state/mod.rs::tests::translation_happens_once_and_leaves_the_old_record_in_place`; `crates/fractal-drivers/src/migrations/delivery_state/mod.rs::tests::deletion_trigger_absent_old_record_makes_this_module_a_no_op` |

-| **Bounded idempotent stream ingress** | A running agent accepts events only for a declared stream. Within the retained 128-receipt ring, concurrent or crash-replayed `(stream, event-id)` publication reuses one canonical filename, conflicting content fails, and supersession archives only the matching keyed predecessor or the stream-wide head through ordinary archive semantics.

-| **Fail-closed observed native DING** | Each unread message becomes one normalized `[DING]` frame. Fresh delivery records ownership, then preserves the one combined bracketed-paste, 0.5 second delay, and Return transaction. PTY and Return success are transport only: `Delivered` additionally requires adapter classification of the expected notice text in a submitted-prompt or queued-message pattern while the lowest live composer is empty or an accepted idle placeholder. Retry never re-pastes and may send one bare Return only after two adjacent `RetainedSafe` observations. A maintained adapter's positive `NotRetained` observation releases only an already archived staged head; unread, blocked, timed-out, errored, unknown, and unrecognized states retain ownership and later FIFO work remains blocked. Ownership prevents duplicate paste across command failures, receipt ambiguity, archive races, and restart adoption without letting a vanished archived head block FIFO indefinitely. Startup backlog otherwise becomes one generic recovery DING; new arrivals remain FIFO; `busy` delivers immediately; only fresh `dnd` defers. | `crates/fractal-drivers/src/ding/tests.rs::poke_text_normalizes_and_bounds_untrusted_fields`; `crates/fractal-drivers/src/ding/tests.rs::malicious_controls_cannot_escape_the_single_paste_frame`; `crates/fractal-drivers/src/ding/tests.rs::pty_delivery_uses_face607_delay_order_and_seconds`; `crates/fractal-drivers/src/ding/tests.rs::maintained_composer_classifiers_require_exact_idle_state`; `crates/fractal-drivers/src/ding/tests.rs::successful_transport_with_retained_or_unproven_pixels_is_not_delivered`; `crates/fractal-drivers/src/ding/tests.rs::ambiguous_transport_receipt_and_retry_errors_retain_staged_ownership`; `crates/fractal-drivers/src/ding/tests.rs::adapter_recognized_notice_with_an_empty_live_composer_is_a_positive_receipt`; `crates/fractal-drivers/src/ding/tests.rs::staged_retry_submits_only_retained_safe_and_requires_a_receipt`; `crates/fractal-drivers/src/ding/tests.rs::staged_retry_keeps_unproven_and_retained_blocked_owned`; `crates/fractal-drivers/src/ding/tests.rs::archive_cancels_staged_ownership_without_submit_or_repaste`; `crates/fractal-drivers/src/ding/tests.rs::archived_not_retained_releases_fifo_without_repasting_owned_notice`; `crates/fractal-drivers/src/ding/tests.rs::unread_not_retained_keeps_fifo_ownership_without_repasting`; `crates/fractal-drivers/src/ding/tests.rs::pty_commands_have_a_real_outer_timeout`; `crates/fractal-drivers/src/ding/tests.rs::session_watch_has_startup_grace_debounce_and_live_reset`; `crates/fractal-drivers/src/ding/tests.rs::new_arrivals_is_fifo_and_archive_receipts_prevent_reding`; `crates/fractal-drivers/src/ding/tests.rs::pending_delivery_ignores_busy_but_respects_fresh_dnd_archive_and_retry`; `crates/fractal-drivers/src/ding/tests.rs::startup_recovery_notice_retries_in_memory`; `crates/fractal-drivers/src/ding/tests.rs::startup_backlog_gets_one_generic_recovery_then_new_arrivals_poke` |
-| **Mutation-only filesystem wakeups** | Supervisor and DING filesystem watchers ignore read/open access events and wake early only for create, modify, rename, or remove events. Their own catalog and inbox reads therefore cannot bypass the bounded timer cadence or form a Linux inotify CPU loop. | `crates/fractal-drivers/src/watch.rs::only_mutations_wake_watch_loops`; `crates/fractal-drivers/src/watch.rs::linux_reads_are_silent_but_real_mutations_wake`; `crates/fractal-drivers/src/ding/tests.rs::idle_ding_does_not_spin_on_its_own_inbox_reads`; `crates/fractal-drivers/src/run/tests.rs::idle_supervisor_does_not_spin_on_its_own_catalog_reads` |
-| **Prompt catalog convergence** | A resident catalog supervisor observes cooperative transaction commits through a constant-cost catalog-generation watcher and authorized direct Agent Spec publication through an independent declaration watcher. Both channels coalesce into the serialized loop without waiting for the periodic audit interval; failure of one leaves the other and the timer fallback available. Runtime/control noise remains excluded. | `crates/fractal-drivers/src/watch.rs::catalog_generation_commit_wakes_catalog_watch`; `crates/fractal-drivers/src/watch.rs::atomic_agent_bundle_publication_wakes_production_shaped_catalog`; `crates/fractal-drivers/src/run/tests.rs::supervisor_wakes_and_launches_a_new_direct_declaration`; `crates/fractal-drivers/src/run/tests.rs::failed_watch_installation_keeps_supervisor_on_timer_cadence` |
-| **Bounded DING PTY probe churn** | An unsafe or active composer retains its FIFO notice but deferred delivery retries use a bounded backoff, so each inbox poll cannot spawn another short-lived PTY probe. | `crates/fractal-drivers/src/ding/tests.rs::deferred_delivery_backoff_bounds_short_lived_pty_attempts` |
-| **Agent-declared presence discipline** | The shipped bus contract requires agents to declare `busy` before executing work, use `available` only while yielding or ready, and reserve `dnd` for an explicit hold. Both native harnesses materialize that contract. Busy remains observable but does not suppress DING; fresh `dnd` is the only delivery gate. | `tests/native_only.rs::clean_path_executes_the_maintained_native_authoring_guide`; `crates/fractal-drivers/src/ding/tests.rs::pending_delivery_ignores_busy_but_respects_fresh_dnd_archive_and_retry` |
-| **Stable roster JSON** | `st2 agents --json [--enrich]` preserves field names, order, null handling, presence, typed desired state and rationale, the retirement compatibility projection, opaque declared Resource descriptors, origin-timed activity, inbox counts, and the appended immutable `id`, mutable `address`, nullable `busAddress`, `observedState`, `driverDiagnostic`, and `context` objects. Declared presence, desired lifecycle, observed harness state, native-driver degradation, and harness context are independent axes: none is derived from another; a missing observed or context record is `null`, while missing diagnostic evidence is explicitly `absent`, never healthy. | `src/agents.rs::agents_json_has_stable_wire_shape`; `src/agents.rs::agents_json_preserves_opaque_declared_resource_descriptors`; `src/agents.rs::observed_state_joins_declared_presence_without_touching_either`; `src/agents.rs::driver_diagnostic_wire_exposes_failure_and_evidence_age_without_identity_payloads`; `src/agents.rs::context_is_a_fourth_axis_that_survives_an_indeterminate_observed_state`; `tests/status_agents.rs::roster_json_and_human_output_distinguish_retirement_from_presence`; `tests/status_agents.rs::roster_keeps_presence_separate_from_suspended_desired_state`; `tests/status_agents.rs::roster_uses_version_1_origin_time_for_last_activity`; `tests/status_agents.rs::roster_joins_a_real_context_record_independently_of_observed_state` |
-| **Agent-declared presence** | Refresh preserves non-DND declared status and advances the version 1 heartbeat. A missing status starts as `available`. Legacy DND migrates without renewing its hold. Version 1 DND is not refreshed. Stale, malformed, or implausibly future heartbeats read as `unknown`. The outer Codex, Claude, and pi session wrappers own a five-minute heartbeat while their provider remains alive. | `crates/fractal-drivers/src/status.rs::refresh_preserves_value_and_changes_heartbeat_bytes`; `crates/fractal-drivers/src/status.rs::refresh_upgrades_legacy_dnd_without_renewing_the_hold`; `crates/fractal-drivers/src/status.rs::refresh_missing_writes_available_default`; `crates/fractal-drivers/src/status.rs::version_1_staleness_and_future_skew_are_bounded`; `crates/fractal-drivers/src/status.rs::malformed_versioned_record_is_unknown_without_mtime_fallback`; `crates/fractal-drivers/src/claude_session.rs::idle_provider_refreshes_presence_without_mcp_input`; `crates/fractal-drivers/src/pi_session.rs::idle_pi_provider_refreshes_presence_without_channel_input`; `crates/fractal-drivers/src/codex_app_server/tests.rs::inbox_fallback_does_not_write_a_fifteen_second_presence_heartbeat` |
-| **Scoped delivery-input wakeups** | Native delivery pumps watch only their inputs: the agent's `resources/inbox` subtree and its `status` file. Runtime records written beside them by the pump's own process group — presence temp siblings, the `harness-state` and `harness-context` records with their locks and staged siblings, stream state — never wake delivery, so a producer that writes on every turn boundary cannot pump its own delivery loop. | `crates/fractal-drivers/src/watch.rs::delivery_watcher_ignores_runtime_records_but_wakes_on_inbox_and_status` |
-| **Observed harness state discipline** | The `harness-state` record is written only by the owning session's driver processes — wrapper, channel, or hooks — serialized by a cross-process lock and coalesced against the on-disk record, atomically and byte-distinct on every write that lands, with freshness from its embedded timestamp and never file mtime; restating an unchanged state touches the record only when the refresh cadence is due. `unknown` is derived, never written: staleness, future skew, malformation, an unsupported schema, and a provably dead pty session each read as `unknown` with a distinct reason; an indeterminate liveness probe downgrades nothing; a missing record is no observation rather than `unknown`; no absence derives a definite state. A writer that loses sight of its harness stops heartbeating instead of refreshing a state it cannot see, and a predecessor session's record is never re-stamped. A reaped provider yields a terminal `ended` record carrying its real exit — written before the stop path's SIGKILL escalation and rewritten from the escalation cover when a grace-window reap observes the real status, proven against the real wrapper binaries of both stop implementations — and never a live state. | `crates/fractal-drivers/src/harness_state.rs::unknown_state_is_derived_and_cannot_be_written`; `crates/fractal-drivers/src/harness_state.rs::malformed_record_is_unknown_without_mtime_fallback`; `crates/fractal-drivers/src/harness_state.rs::staleness_and_future_skew_derive_unknown_with_distinct_reasons`; `crates/fractal-drivers/src/harness_state.rs::a_dead_session_reads_unknown_even_while_fresh_but_ended_survives`; `crates/fractal-drivers/src/harness_state.rs::every_landed_write_is_byte_distinct_and_fresh_restatements_do_not_write`; `crates/fractal-drivers/src/harness_state.rs::a_chatty_producer_restating_its_state_causes_zero_writes`; `crates/fractal-drivers/src/harness_state.rs::concurrent_writers_defer_to_the_on_disk_record_not_their_cache`; `crates/fractal-drivers/src/harness_state.rs::a_predecessor_sessions_record_is_never_heartbeat_eligible`; `crates/fractal-drivers/src/harness_state.rs::missing_record_reads_as_none_not_unknown`; `crates/fractal-drivers/src/codex_app_server/tests.rs::pump_publishes_observations_and_stops_heartbeating_on_evidence_loss`; `crates/fractal-drivers/src/claude_session.rs::a_provider_killed_mid_turn_reads_ended_rather_than_active`; `crates/fractal-drivers/src/claude_session.rs::a_clean_provider_exit_writes_the_terminal_record`; `tests/harness_state_teardown.rs::stop_escalation_writes_the_terminal_record_before_sigkill`; `tests/harness_state_teardown.rs::opencode_stop_escalation_writes_the_cover_record_before_sigkill`; `tests/harness_state_teardown.rs::opencode_graceful_stop_records_the_real_reaped_exit` |
-| **Harness context discipline** | The numeric `harness-context` record is a sibling of `harness-state` and shares none of its ownership machinery: `incarnation` is provenance and never a fence, and a straggler's write lands rather than being refused. A reading is written only when it enters a different bucket of `usedPercent`, when a compaction edge arrives, when proven Claude account-window exhaustion changes, or when the record is older than the heartbeat, so a chatty producer cannot inflate the write rate; Codex account-window occupancy does not classify availability without its separate credit metadata. Every landed write is byte-distinct, and freshness comes from the record's own `observedAtMs`, never file mtime. A withheld value is carried as `null` and never fabricated from zero, the previous reading, or a division st2 could have done itself, and a reading above the window is carried unclamped. There is no `unknown` on this axis: past the horizon the reading is returned marked `stale` with its age, surviving every derivation the categorical record makes, while an unparseable record, a foreign schema, an uninterpretable harness, and an untrustworthy clock each read as absent. The relaunch claim removes the record, and Doctor's high-reading and stale-record lines are advisory in both directions and never change its exit status. Where a producer ships, its numerator is the harness's own and is pinned to the build it was measured on: pi's `tokens` is the last assistant message's `totalTokens` and omp's is its prompt figure, so neither harness's arithmetic can be published under the other's tag, and a harness bump that changes a number's meaning without changing its shape fails a fixture rather than shipping. A harness that positively reports it does not know its own occupancy is forwarded as withheld in the same write as the compaction edge that emptied it, a compaction edge whose harness names no reason yields `unknown` rather than an invented word, and a durable count the producer cannot read narrows to st2 counting edges rather than losing them. | `crates/fractal-drivers/src/harness_context.rs::a_reading_inside_the_written_bucket_does_not_write_and_a_crossing_does`; `crates/fractal-drivers/src/harness_context.rs::claude_rate_limit_exhaustion_and_reset_crossings_land_inside_one_usage_bucket`; `crates/fractal-drivers/src/harness_context.rs::codex_account_window_exhaustion_does_not_prove_the_runtime_is_blocked`; `crates/fractal-drivers/src/harness_context.rs::a_withheld_percent_has_no_bucket_and_only_a_compaction_or_heartbeat_writes`; `crates/fractal-drivers/src/harness_context.rs::a_record_older_than_the_heartbeat_is_rewritten_and_every_landed_write_is_byte_distinct`; `crates/fractal-drivers/src/harness_context.rs::a_compaction_always_lands_with_its_trigger_and_may_carry_a_durable_count`; `crates/fractal-drivers/src/harness_context.rs::withheld_values_are_null_and_are_never_fabricated`; `crates/fractal-drivers/src/harness_context.rs::a_reading_above_the_window_is_carried_unclamped`; `crates/fractal-drivers/src/harness_context.rs::a_stale_reading_is_returned_with_its_age_rather_than_derived_away`; `crates/fractal-drivers/src/harness_context.rs::freshness_comes_from_the_record_bytes_and_never_from_file_mtime`; `crates/fractal-drivers/src/harness_context.rs::additive_fields_decode_but_foreign_schema_and_harness_read_as_nothing`; `crates/fractal-drivers/src/harness_context.rs::a_record_beyond_the_future_skew_bound_reads_as_nothing`; `crates/fractal-drivers/src/harness_context.rs::a_straggler_lands_and_is_visible_as_provenance_rather_than_being_refused`; `crates/fractal-drivers/src/harness_state.rs::the_relaunch_claim_removes_the_harness_context_record`; `src/agents.rs::context_is_a_fourth_axis_that_survives_an_indeterminate_observed_state`; `tests/doctor.rs::harness_context_doctor_lines_are_advisory_and_never_change_the_exit_status`; `crates/fractal-drivers/src/pi_channel.rs::the_pi_0_84_2_fixture_pins_total_tokens_as_the_numerator`; `crates/fractal-drivers/src/pi_channel.rs::the_omp_18_0_9_fixture_pins_prompt_input_as_the_numerator`; `crates/fractal-drivers/src/pi_channel.rs::a_pi_compaction_withholds_the_reading_it_emptied_in_the_same_write`; `crates/fractal-drivers/src/pi_channel.rs::an_omp_compaction_yields_unknown_because_the_event_names_no_reason`; `crates/fractal-drivers/src/pi_channel.rs::an_unreadable_durable_count_degrades_to_counting_edges_not_to_losing_them`; `crates/fractal-drivers/src/pi_channel.rs::context_frames_decode_conservatively_or_not_at_all`; `crates/fractal-drivers/src/pi_channel.rs::the_measured_pi_release_is_the_one_the_extension_gate_pins` |
-| **Replicated-path discipline** | st2 pins the exact driver-record names it expects the replication transport's include list to carry — `harness-state` and `harness-context` — and both readers derive their paths from that list, so a rename cannot silently stop replication in a repository that does not own the list. A harness-context write stages in the catalog control plane, outside the complete `agents` identity namespace, after validating canonical ancestry and same-filesystem atomic rename. Current-catalog identity walkers overlook only an exact legacy `.harness-context.tmp-<numeric-pid>-<numeric-counter>` regular non-symlink host child and leave it untouched; directories, symlinks, special files, generic dotfiles, near misses, and prepared topology remain strict. `harness-state` still stages beside itself, pending its own change; the shared write helper takes the staging directory as an argument precisely because the two answer this differently. | `crates/fractal-drivers/src/harness_context.rs::the_replicated_driver_record_names_are_pinned`; `crates/fractal-drivers/src/harness_context.rs::writes_stage_in_catalog_control_and_clean_up_after_success_or_failure`; `crates/fractal-drivers/src/catalog_transaction.rs::current_projection_ignores_and_preserves_an_exact_legacy_staging_file`; `crates/fractal-drivers/src/catalog_transaction.rs::current_projection_rejects_legacy_shape_type_confusion_and_near_misses`; `crates/fractal-drivers/src/message.rs::transition_addressability_ignores_and_preserves_exact_legacy_staging_files`; `crates/fractal-drivers/src/message.rs::transition_addressability_rejects_legacy_type_confusion_and_near_misses`; `tests/catalog_apply.rs::snapshot_ignores_and_preserves_an_exact_legacy_harness_context_staging_file` |
-| **Status-line slot chaining** | Claude's `statusLine` is a single slot whose winning declaration replaces the others outright, and `.claude/settings.local.json` — the file st2 materializes — wins over every other settings file. So st2's entry there is a tee: it records the reading and then invokes the operator's own renderer, resolved from `$ST_CLAUDE_STATUSLINE_RENDERER` and then `~/.claude/statusline-renderer.json`, first hit wins and never both. Where no renderer resolves, and wherever a resolved renderer fails, the tee writes NOTHING to stdout and puts its diagnostic on stderr: the payload is machine JSON, so echoing it into the slot is strictly worse for the operator than a blank row. Recording is unaffected by which arm runs. | `tests/claude_statusline.rs::the_tee_records_the_reading_and_hands_the_same_payload_to_the_env_renderer`; `tests/claude_statusline.rs::the_operator_file_supplies_the_renderer_when_no_variable_does`; `tests/claude_statusline.rs::the_variable_wins_over_the_file_and_the_file_is_never_also_run`; `tests/claude_statusline.rs::with_no_renderer_the_tee_renders_nothing_rather_than_the_raw_payload`; `tests/claude_statusline.rs::a_recording_failure_still_renders_the_status_line`; `tests/claude_statusline.rs::a_renderer_that_exits_non_zero_leaves_stdout_empty`; `tests/claude_statusline.rs::a_renderer_file_that_is_not_executable_leaves_stdout_empty`; `tests/claude_statusline.rs::without_st2_on_path_the_script_drains_stdin_and_renders_nothing`; `tests/claude_statusline.rs::the_rendered_registration_names_the_chaining_tee_and_carries_the_whole_slot` |
-| **Version-pinned producer arithmetic** | Every harness-context producer publishes the number its own harness means by that number, and each one is pinned to the exact build the meaning was measured on: Claude's integer percent over `total_input_tokens` and `context_window_size` (2.1.250), Codex's window with the 12,000 baseline subtracted from both sides (codex-cli 0.151.0), pi's last assistant `totalTokens` and omp's prompt-only `input` (0.84.2 and 18.0.9), and OpenCode's last non-summary assistant total over the providers window (1.18.25). The failure this bounds is a harness bump that changes what a key means without changing its shape, which no type gate and no round-trip assertion can see, so each fixture decodes a verbatim capture, asserts the version literally, and asserts the wrong numerator the same capture would yield. | `crates/fractal-drivers/src/claude_session.rs::a_mid_session_statusline_payload_yields_claudes_own_triple`; `crates/fractal-drivers/src/claude_session.rs::a_pre_turn_statusline_payload_withholds_rather_than_reporting_zero`; `crates/fractal-drivers/src/codex_app_server/tests.rs::codex_context_recomputes_the_captured_reading_and_pins_its_verified_version`; `crates/fractal-drivers/src/pi_channel.rs::the_pi_0_84_2_fixture_pins_total_tokens_as_the_numerator`; `crates/fractal-drivers/src/pi_channel.rs::the_omp_18_0_9_fixture_pins_prompt_input_as_the_numerator`; `crates/fractal-drivers/src/opencode_session.rs::captured_opencode_turns_publish_the_assistant_total_over_the_providers_window` |
-| **Native-driver diagnostics are bounded and recoverable** | One additive-tolerant `st2.driver-diagnostic.v1` snapshot exposes the earliest failing native-driver boundary through closed driver/stage/reason/source/support vocabulary and origin-timed evidence age. Absent, malformed, foreign, unknown, and wrongly paired records never read healthy. Stage recovery clears only its own failure and removes the record after final recovery without changing prompt submission, retry, read-back, or archive semantics. A Codex automatic remote resume removes provider-rejected permission flags from the TUI argv, projects their exact approval and sandbox policy through typed `thread/resume`, and verifies the effective response. A rejected declared resume policy or model/effort mismatch fails before thread binding; the supervisor parks repeated failed starts until the declaration changes, without a declaration-dropping fallback. A declared-argument rejection fails before spawn without leaking free-form option values into the typed record or wrapper diagnostic; the resume proof may name only closed approval, reviewer, and sandbox values. A rejected provider credential is published on its own `providerAuth` stage from the harness's own typed turn result — never from provider prose, and never from an auth-class flag a capacity, policy, or retry class also sets — outranking the delivery and read-back symptoms it causes while the producer gates outrank it; only a turn that reached its ordinary end clears it, and no credential knowledge or remedy text enters st2. Roster and Doctor share the typed reader/repair policy — Doctor advising on absence only for a driver that publishes a boundary result on every launch; telemetry labels contain only bounded driver/stage/reason/source/support/outcome values, never versions, identities, prompts, messages, or paths. | `crates/fractal-drivers/src/driver_diagnostic.rs::every_stage_reason_and_source_has_bounded_wire_vocabulary`; `crates/fractal-drivers/src/driver_diagnostic.rs::degraded_launch_is_visible_until_an_exact_launch_clears_it`; `crates/fractal-drivers/src/driver_diagnostic.rs::additive_fields_decode_but_malformed_foreign_and_unknown_records_are_indeterminate`; `crates/fractal-drivers/src/driver_diagnostic.rs::recovery_clears_only_its_stage_and_reveals_the_next_failure`; `crates/fractal-drivers/src/driver_diagnostic.rs::a_credential_rejection_is_evidence_only_from_a_typed_turn_result`; `crates/fractal-drivers/src/driver_diagnostic.rs::a_rejected_credential_outranks_its_symptoms_but_not_the_producer_gates`; `crates/fractal-drivers/src/codex_app_server/tests.rs::automatic_remote_resume_omits_permission_overrides_but_fresh_launch_is_exact`; `crates/fractal-drivers/src/codex_app_server/tests.rs::rejected_declared_resume_settings_fail_without_downgrading_the_policy`; `crates/fractal-drivers/src/codex_app_server/tests.rs::successful_resume_with_wrong_model_or_effort_fails_before_binding`; `crates/fractal-drivers/src/codex_app_server/tests.rs::rejected_declared_options_fail_before_launch_without_leaking_values`; `crates/fractal-drivers/src/claude_session.rs::stop_failure_classifies_only_the_credential_class_as_provider_auth`; `crates/fractal-drivers/src/claude_session.rs::a_rejected_claude_credential_stands_until_a_turn_reaches_its_ordinary_end`; `crates/fractal-drivers/src/codex_app_server/tests.rs::a_rejected_codex_credential_reads_provider_auth_while_a_quota_failure_does_not`; `crates/fractal-drivers/src/codex_app_server/tests.rs::protocol_schema_gate_requires_distinct_credential_and_stable_quota_error_words`; `crates/fractal-drivers/src/opencode_session.rs::delivery_and_read_back_boundaries_publish_and_clear_diagnostics_without_changing_retry`; `crates/fractal-drivers/src/metrics.rs::driver_diagnostic_metric_attributes_are_exactly_the_bounded_axes`; `tests/doctor.rs::native_driver_diagnostic_roster_and_doctor_agree_and_recovery_clears`; `crates/fractal-drivers/src/pi_channel.rs::only_omps_own_credential_class_becomes_provider_auth`; `crates/fractal-drivers/src/pi_channel.rs::a_rejected_omp_credential_stands_until_a_turn_reaches_its_ordinary_end`; `crates/fractal-drivers/src/pi_channel.rs::the_pi_channel_publishes_no_credential_verdict`; `tests/doctor.rs::a_rejected_provider_credential_advises_while_absence_stays_silent` |
-| **Retirement health** | A retired declaration is healthy only after every declared task ID is absent. Any live or dead declared task record reports incomplete retirement; retired declarations do not require presence.

-| **Suspension health** | A suspended declaration is healthy when no declared task is live and every retained dead record is explicitly keep-pinned. It requires no presence, but this weaker result never proves retirement.

-| **Archival leaves the live catalog** | `st2 catalog archive` moves a retired identity's whole directory — declaration and `resources/` byte-identical — under the catalog control plane's `.st2/archive`, where discovery structurally cannot reach it, and records one tombstone row in `st2 catalog graph --json`. Eligibility fails closed: a running or suspended declaration, any surviving live or dead declared task record, and any remaining declaration that still names the identity as `supervisor` each refuse before anything moves, and `--dry-run` proves the plan without creating the archive root. An archived directory with no readable tombstone is unexplained control-plane state that makes the graph incomplete. `st2 catalog unarchive` is the exact reverse move. | `tests/catalog_archive.rs::archive_moves_a_retired_seat_out_of_discovery_with_its_resources_byte_identical`; `tests/catalog_archive.rs::archive_refuses_a_running_or_suspended_declaration`; `tests/catalog_archive.rs::archive_refuses_while_any_declared_task_record_survives`; `tests/catalog_archive.rs::archive_refuses_an_identity_another_declaration_still_names_as_supervisor`; `tests/catalog_archive.rs::dry_run_reports_the_plan_and_changes_nothing`; `tests/catalog_archive.rs::an_archived_directory_without_a_tombstone_makes_the_graph_incomplete`; `tests/catalog_archive.rs::unarchive_restores_the_identity_byte_identically_and_clears_its_tombstone` |
-| **Retirement archives itself after its grace period** | Each `st2 up` reconcile pass archives the local seats whose retirement outlived the catalog's `archive-after` (default `7d`; `"0"` disables the step), through the same fail-closed eligibility as the verb and at most 25 seats per pass. It never queues for the authoring lock: a contended lock skips the step. The grace period is measured from the supervisor's first observation of the retirement, recorded under `.st2/retired-observed.json` and never in the spec, and that ledger is reconciled to exactly the currently retired seats — so un-retiring drops the row and re-retiring serves a fresh grace period. | `tests/supervisor_auto_archive.rs::a_pass_records_a_fresh_retirement_and_archives_nothing`; `tests/supervisor_auto_archive.rs::a_retirement_older_than_the_grace_period_is_archived_with_a_tombstone`; `tests/supervisor_auto_archive.rs::archive_after_zero_disables_the_pass_entirely`; `tests/supervisor_auto_archive.rs::a_pass_archives_at_most_twenty_five_seats_and_drains_the_rest_next_pass`; `tests/supervisor_auto_archive.rs::a_contended_authoring_lock_skips_the_pass_instead_of_blocking_it`; `tests/supervisor_auto_archive.rs::un_retiring_a_seat_inside_the_grace_period_restarts_its_clock` |
-| **Crash loops surface** | A task parked by a fail-mode restart policy notifies its supervisor once over the bus. | `crates/fractal-drivers/tests/run.rs::surface_crash_loop_notifies_the_supervisor_over_the_bus` |
-| **Parked tasks are visible and individually recoverable** | A parked task is reported alongside an unmodified runtime observation as a complete known fault; only an unbelievable marker fails closed. Park markers and unpark requests share the exact canonical catalog-folder plus host ownership scope, and the projected recovery argv carries both axes, so same-host supervisors cannot see, delete, consume, or advertise recovery into each other's channels even for the same task ID. A projected park whose supervisor generation is gone is positively not parked. An explicit per-task unpark clears that task's park and spent budget so it is launchable again and stays recovered past `interval`, releases no other parked task, restarts no healthy peer, and restores the agent's derived DING. | `crates/fractal-drivers/src/flapping.rs::unpark_restores_a_launchable_task_not_just_a_cleared_flag`; `crates/fractal-drivers/src/flapping.rs::unpark_is_per_task_and_reports_whether_it_changed_anything`; `crates/fractal-drivers/src/park.rs::same_host_supervisors_isolate_markers_and_requests_by_catalog`; `crates/fractal-drivers/src/park.rs::a_marker_from_a_dead_supervisor_reads_as_not_parked`; `crates/fractal-drivers/src/park.rs::published_parks_are_readable_and_clear_when_the_task_recovers`; `crates/fractal-drivers/src/park.rs::an_unbelievable_marker_is_indeterminate_not_absent`; `crates/fractal-drivers/src/park.rs::a_request_is_consumed_exactly_once`; `crates/fractal-drivers/src/task_inventory.rs::a_parked_task_reports_its_fault_alongside_a_truthful_runtime_state`; `crates/fractal-drivers/src/task_inventory.rs::an_unbelievable_park_marker_makes_the_envelope_incomplete`; `tests/task_inventory_cli.rs::projected_recovery_targets_its_exact_catalog_and_host_despite_ambient_defaults`; `crates/fractal-drivers/tests/run.rs::an_operator_recovers_one_parked_task_without_disturbing_a_healthy_peer`; `crates/fractal-drivers/tests/run.rs::an_unpark_request_for_a_task_that_is_not_parked_says_so` |

-| **Native flat root** | Without an authored override, catalog tasks, eval messaging, shell helpers, and DING all use the catalog itself as `ST_ROOT`; no nested bus directory is synthesized. | `src/eval_run.rs::bus_root_expands_st_root_else_defaults`; `tests/eval_run_e2e.rs::st2_eval_runs_a_benign_folder_to_a_pass_verdict`; `tests/pty.rs` |
-| **Resource observation is state-first, atomic, and fenced** | ABI-3 periodic publication and demanded `Published` results reuse one bounded `Publication` payload and one host acceptance, digest, relevance, typed-fact, and catch-up core; the host never trusts a runtime digest or observation timestamp. Demand reaches only a resident runtime that explicitly declares `capability "demand"`. Every `Observe` carries a positive watermark and the exact owner, binding, and registration, and exactly one matching `Unchanged`, `Failed`, or `Published` atomic result closes it. One outstanding dispatch plus one latest trailing watermark coalesces bursts without losing in-flight arrivals. Backpressure retains queued demand, replacement fences stale output, restart and provider failure settle honestly, and client disconnect or wait expiry never cancels accepted work. | `tests/resource_profile_supervisor_e2e.rs::production_demand_jobs_coalesce_queue_disconnect_and_fence_generation`; `tests/resource_profile_supervisor_e2e.rs::durable_admission_retains_the_256_request_boundary_without_a_runtime`; `tests/resource_profile_supervisor_e2e.rs::production_component_preserves_resync_filter_catch_up_and_scope_isolation`; `tests/resource_profile_supervisor_e2e.rs::supervisor_spawns_vista_capability_and_preserves_stable_snapshot`; `tests/agent_resource.rs::refresh_cli_reports_exact_receipts_and_wait_expiry_keeps_the_request`; `crates/fractal-drivers/src/resource_observe.rs::tests::receipt_evidence_shape_matches_atomic_results` |
-| **Atomic resource proposal publication** | Every changed resource publication is one host-owned compare-and-swap fenced by binding generation, state revision, and prior carrier digest. A persistent cross-process lock admits at most one proposal from the same prior. The content-derived proposal ID binds the accepted carrier digest and semantic outbox envelope; the durable intent becomes eligible only with the exact canonical carrier, then folds into one authoritative catch-up state. A pre-carrier crash exposes old state, a post-carrier crash catches up on restart, and retry after a lost acknowledgement returns the durable receipt without another transition. Ordinary reconciliation fails closed on out-of-band divergence after a committed intent; only an explicit generation-advance recovery may re-adopt the canonical carrier or its absence while invalidating the old intent and fence. | `crates/fractal-drivers/src/resource_profile.rs::tests::atomic_publication_fences_races_and_survives_crash_restarts`; `crates/fractal-drivers/src/resource_profile.rs::tests::generation_advance_explicitly_recovers_diverged_or_missing_carrier` |
-| **Pass progress is independent of publication** | A reconcile pass completes whether or not resync publication is making progress. Publication runs on its own thread, so a pass's per-seat watch-set handshakes never wait for a catalog lock, a stream lock, or a refused publication. One publication is outstanding per subscription at a time, and a queued publication is dropped when its subscription is deactivated or removed by a refresh, so nothing is published to a seat the pass has already decided receives no events. | `crates/fractal-drivers/src/run/tests.rs::reconcile_pass_completes_while_a_resync_publication_is_blocked`; `crates/fractal-drivers/src/resync/tests.rs::a_flush_never_hands_off_a_subscription_whose_publication_is_outstanding`; `crates/fractal-drivers/src/resync/tests.rs::deactivation_drops_only_that_recipients_queued_publication`; `crates/fractal-drivers/src/resync/tests.rs::a_refresh_drops_a_queued_publication_for_a_subscription_it_removed` |
-| **Terminal refusals are classified, not retried** | A refused resync publication is classified by what could admit it later. A recipient that is declared but not running parks its reservation: it is attempted once, captures and schedules nothing while parked, and re-arms with its exact reserved bytes when a refresh carries that recipient again. An ambiguous recipient, a foreign owning host, and an undeclared stream are permanently refused: the reservation is dropped and the carrier baseline advances so the same transition is not re-captured. Everything else, including an absent declaration, stays retryable. | `crates/fractal-drivers/src/resync/tests.rs::a_not_running_recipient_parks_its_reservation_and_is_attempted_once`; `crates/fractal-drivers/src/resync/tests.rs::a_parked_reservation_re_arms_and_replays_when_its_recipient_runs_again`; `crates/fractal-drivers/src/resync/tests.rs::a_permanently_refused_reservation_is_dropped_and_not_recaptured`; `crates/fractal-drivers/src/resync/tests.rs::refusals_are_classified_by_what_could_admit_them_later` |
-| **Unbindable running session sockets fail at admission** | Host-scoped validation rejects a running pty task whose session socket path would exceed the portable 104-byte `sun_path` bound, because `pty` refuses that bind and the task can then never spawn. Suspended and retired declarations bind no socket and are accepted, while later activation restores the same refusal before launch. The bound comes from the pty root resolved for the RUNTIME catalog the caller names, never from the tree under inspection: publication admits a candidate through a disposable projection nested in the catalog, and measuring that tree charges every identity for the projection's own depth and refuses declarations whose real socket is bindable. Only a deliberately context-free validation omits the guard. It is not a fixed identity length either, only that host's running pty tasks are judged, and the diagnostic names the resolved path and byte overage. A park whose cause is that same unbindable path does not advise `st2 unpark`, which would relaunch into the identical failure. | `tests/agent_publish.rs::publication_judges_the_socket_bound_against_the_runtime_catalog_not_the_projection`; `tests/agent_publish.rs::publication_still_refuses_an_unbindable_canonical_socket_path`; `tests/validate.rs::an_unbindable_session_socket_path_is_rejected_at_admission`; `tests/validate.rs::inactive_unbindable_session_sockets_are_accepted`; `tests/validate.rs::activating_an_unbindable_session_socket_restores_the_admission_refusal`; `tests/validate.rs::another_hosts_long_identity_is_not_judged_against_this_hosts_pty_root`; `tests/validate.rs::a_long_exec_task_id_is_not_a_socket_path_issue`; `crates/fractal-drivers/src/run/tests.rs::session_socket_overage_is_derived_from_the_resolved_root`; `crates/fractal-drivers/tests/run.rs::a_structurally_unrecoverable_park_does_not_advise_unpark` |
-| **Marker-matched declaration authority** | Every st2 write path that rewrites a declaration carrying `meta { managed-by "nix" }` admits it only from a caller asserting exactly the marker that declaration carries: the lifecycle verb and the compare-and-swap `agent publish` both refuse a mismatched marker, an unmarked subject, an unresolvable multi-marker declaration, and an empty or padded assertion before any write, while presentation, address, stream, and Resource authoring refuse a Nix-owned declaration outright. Publication reads that authority from the incumbent, so creating a declaration and republishing byte-identical bytes stay open — neither replaces bytes another writer owns. A lifecycle edit rewrites nothing but the lifecycle line and refuses every newly introduced core catalog error, while allowing repair or teardown when unrelated errors already exist. | `src/agent_author.rs::marker_matched_lifecycle_authority_is_exact_and_source_preserving`; `src/agent_author.rs::marker_matched_lifecycle_delta_refuses_a_new_error`; `tests/agent_desired_state.rs::valid_retirement_ignores_an_unrelated_preexisting_core_error`; `tests/agent_desired_state.rs::cli_managed_by_authority_retires_a_projected_seat_and_refuses_every_inexact_claim`; `tests/agent_publish.rs::publication_honours_the_incumbent_ownership_marker`; `tests/agent_publish.rs::publication_refuses_an_unresolvable_owner_and_repairs_unreadable_bytes` |
-| **Proof references resolve** | Every qualified test named in this table exists in its named source file, so stale invariant claims fail the suite instead of silently surviving a refactor. | `tests/invariants.rs::qualified_proof_references_resolve` |

+### A message's state from its seat's host
+
+A seat's host can keep how far its mail got (delivered, read, closed) on that host alone, and other
+hosts then ask it. A message resource whose recipient's seat runs on such a host carries
+`status_from: {host, state, reason?}`:
+- `state: "answered"`: the resource's own `state` is the further of this host's records and that
+  host's answer. A message that host closed is history (`operational.reasons: ["closed"]`).
+- Any other word, such as `unknown`: that host did not answer in time, and `state` is only this
+  host's own records, which can be behind. `reason` says why. A client shows the state as unknown.
+A view waits at most a second for a host, and does not ask a host that missed for half a minute.
+Without `status_from`, this host's own records are the whole answer, as on older daemons.
+
+A fault's `target_states` entry for such a message, and a step's `wake.acknowledged_by` in a
+mission's detail, take the host's answer the same way: the further of the two. The answer never
+feeds a resource's `revision` or `updated_at`, which stay monotonic. A client sees a change in it
+on its next read, and a subscription sends it with the next frame that something else triggers.

 fails, nothing runs), runs GC with `--fetch --apply --open-heads-from`, keeps 30 days of summaries and plans, and
 stores each summary as a new version of the Fractal document `doc/fleet/factory/evidence-gc/runs`. On a host that also runs the evidence log (`~/.local/bin/evidence-log-timer`
 and `~/.config/evidence-log/signer.json` present), the wrapper passes `--before-delete`, so `evidence-log gc --publish`
 writes GC's lines and publishes the log before anything is deleted; if that fails, nothing is deleted.
 
+The wrapper passes `--resume-state` with `pending-plan.json` in its state directory. The complete original plan is fsynced before
+its hook runs and held under a file lock. A killed or failed deletion leaves that journal in place. The next run finishes it
+before reading another open-head list, fetching the evidence namespace, or recomputing record and input-key protection. Remote
+progress is authoritative: refs already gone need no push, and every remaining deletion is leased to its original object id.
+Migration replay keeps an already-created matching destination; a changed ref, remote, repository or hook is refused. Whole-group
+atomic pushes and remote protection remain in force. For live migrations and redundant-name cleanup, each deletion batch first
+re-reads the replacement from the remote and requires its original object id; these records remain live and need no GC line.
+Local cleanup is idempotent too, including a kill after its transaction
+committed but before the journal was removed. Protection-kept groups are a completed outcome: their remaining names stay
+remote, the journal closes, and the next run reads fresh open heads and plans again. Other failures retain the journal.
+The journal is not part of the 30-day summary cleanup.
+The saved plan has a unique `operation_id`; in journal mode `plan_sha256` includes that id with `delete` and `migrate`. The same
+operation keeps its hash on resume, while a later operation over identical refs gets a distinct GC marker. The pure plan's choices
+and `inputs_sha256` remain deterministic; commands without journal mode keep their existing plan hashes.
+A newly created tree-prefixed alias still incurs the existing per-name verification on its first log pull, even if that object
+was verified under another name. Checkpointed pulls retain that progress across interruptions; GC resume itself does not replan
+or re-verify the records. Reusing verification across aliases is a separate optimization.
+
+Every resumed attempt runs the original hook again before any deletion, so the signed GC lines must still publish through the
+existing fast-forward guard. A resumed plan is marked in its plan file: its hook reuses existing GC lines without duplicating them
+or dropping copies of newer records. If an old target was logged again after this operation's GC line, resume refuses its
+deletion even if a later GC line followed. Pending-name expiration is a separate concern; it is unchanged here. A failed publication leaves the previous pending set and copies intact and deletes no
+remote refs. Its signed local GC commit can remain and be published by an intervening pull while copies are retained; finishing
+the journal converges that state. Commands without a journal require a later successful GC run to converge after this failure.
+The wrapper uses `--no-wait` for the log lock, refusing promptly when a pull is active; a collision can defer deletion until the
+next daily invocation. The hook's 600-second limit and the service's one-hour limit are unchanged. The durable journal allows the next scheduled invocation to continue.

+step; `harness.answer` remains unavailable with `adapter_missing`, even when ingestion
+is enabled. There is no ask override, terminal input, or native settlement path.
+
+The extension opens observation at `tool_execution_start`, using its finalized native
+arguments, not the earlier modifiable `tool_call` input. Native call ids are SHA-256
+digested before they enter the durable native-event outbox.
+Question ids are zero-based native array ordinals (`q0` first, `q15` sixteenth);
+option counts retain native order without sending labels. OMP single-select positional
+answers require one option (`required:true`); native multi-select permits no selected
+options (`required:false`). Other/note values never cross this observation path.
+
+Only the exact managed `driver omp` wrapper generation can ingest observations,
+through the local native route. Its kernel Unix connector PID/birth must agree with
+the physical terminal-wrapper witness, revalidated under the provider record lock.
+Its launch configuration must independently opt in. Agent, runtime incarnation and
+ready native-session binding must agree. Persons, tiles, ordinary agent requests
+and Fabric loopback cannot use that route. A close must refer to a question opened
+by that same binding; unknown/foreign closes write nothing. Replayed opens and closes
+are idempotent. A reused call identity with different descriptors is refused.
+Legacy PTY records without a boot id may establish daemon identity through their
+matching live start token; this does not relax the independent exact-wrapper
+custody or launch/binding checks above.
+The common native identity-proof boundary follows provider, physical runtime and
+daemon-selected source-path checks; question observations additionally prove the
+exact wrapper before that boundary. Neither forged observations nor closes may
+write claims or shared delivery diagnostics. Observation admission never promotes
+a mailbox lease or records mailbox bind-refusal diagnostics.
+
+Native successful completion records `answered_elsewhere`, a structured native timeout
+records `expired`, and error completion records `cancelled`. O1a records closure status
+only: resolution answers are empty and no person receipt is created. Disconnection,
+session switching, absence from a snapshot and elapsed time do not invent a closure.
+The durable outbox retains opens/closes across channel/daemon interruption; the
+extension also replays retained observations after a pipe reconnect. Retention is
+bounded at 256 observed calls per native session; once full, the extension stops
+observing new calls but retains the existing calls and their closes. A true native
+session switch starts a new observation set.
+Observations refused for a disabled receiver or a superseded runtime/session binding
+are retired without inventing a close, so they cannot block unrelated native events.

+Observation metadata is not a proof that a web selection can be executed. In particular,

 | **Native diagnostics** | The earliest failing native boundary is projected: producer gates outrank a rejected credential, and the credential outranks delivery and read-back symptoms. Recovery clears only its own stage. Malformed, foreign or unknown records read as indeterminate, never healthy.

+| **Work scope lifetime** | Exec and PTY work survives an abrupt parent-service kill with the same incarnation and can then stop. Scope launch preserves literal environment values. Bound-scope retirement kills escaped descendants while preserving a neighbor. These controls require a real systemd user manager. | `crates/fractal-runtime/tests/scope_cascade.rs::exec_survives_parent_service_sigkill_with_the_same_incarnation_and_stops`; `crates/fractal-runtime/tests/scope_cascade.rs::pty_survives_parent_service_sigkill_with_the_same_incarnation_and_stops`; `crates/fractal-runtime/tests/scope_cascade.rs::literal_environment_is_preserved_across_a_work_scope`; `crates/fractal-runtime/src/isolate/retirement_native_tests.rs::a_bound_scope_retires_escaped_descendants_and_preserves_a_neighbor` |
 | **Proof references** | Every qualified test in this table exists in its named source. Missing or wrongly qualified proofs fail the suite; at least twenty qualified references must remain. | `crates/fractal/tests/invariants.rs::qualified_proof_references_resolve` |
 
-The root st2 proof table and test suite remain while their retirement prerequisites are prepared. Stop escalation and status-line process controls need current-runtime ports before the root tests can retire. The current-runtime scope controls need explicit real-systemd VM qualification; ignored tests are not evidence of a pass. Native delivery migration proofs retire only with their separately reviewed bridge removal.
+The current-runtime stop and status-line process controls own the surviving obligations.
+The four work-scope controls require explicit real-systemd VM qualification; a resolved
+reference or an ignored test is not an execution pass. Native delivery migration proofs
+retire only with their separately reviewed bridge removal and recorded fleet prerequisites.

+# Retained native driver contracts
+
+These requirements survive retirement of the catalog CLI and its VRS. They apply
+to the shared driver and current runtime boundaries named below. The
+[native invariants](invariants.md) identify executable proofs and their limits;
+this document does not make a passing source-reference check an execution result.
+
+## Process ownership and launch bytes
+
+The control plane may be replaced without killing or replacing its durable work.
+Stopping that work requires an explicit lifecycle action. Parent-bound test
+helpers and durable work have separate lifetimes, and cleanup must target the
+owned generation without touching neighboring work. The real-systemd controls in
+[the work-scope invariant](invariants.md) exercise parent-service death, literal
+environment values and escaped-descendant retirement.
+
+Every added launch wrapper preserves the program and ordered arguments as opaque
+OS strings. Systemd v254 and newer require `--expand-environment=no` before the
+`--` separator. Versions 236–253 directly execute scope arguments and omit that
+unsupported option. Version and user-manager probes must establish scope support;
+the documented degraded mode grants no scope-isolation proof. A fixed description
+keeps task argument bytes out of the D-Bus description. Neither shell quoting nor
+dollar/percent rewriting may change caller-owned bytes. The implementations are
+[`fractal-runtime::isolate`](../../crates/fractal-runtime/src/isolate.rs) and the
+[retained driver wrapper](../../crates/fractal-drivers/src/isolate.rs).
+
+Launch environment values travel in the inherited environment, with only variable
+names in generated PTY environment arguments. Canonical runtime placement owns
+`PTY_ROOT`; the deprecated `PTY_SESSION_DIR` is removed after the overlay. Launcher
+failure claims carry bounded diagnostic kinds and exit status rather than raw
+captured output. This does not remove values from explicitly authored arguments
+or from authored replicated declarations.
+
+Bounded helper teardown includes the helper's process group and descendants. The
+direct child is reaped or its wait ownership is transferred to the shared reaper.
+[`fractal-drivers::process`](../../crates/fractal-drivers/src/process.rs) retains
+at most the last 256 KiB of each diagnostic stream and reports truncation.
+Structured payload callers opt into an explicitly named full-stdout helper;
+stderr remains bounded. The cap, teardown and reaping requirements formerly
+identified as R32, R34 and decision 0007 remain in force for these shared helpers.
+
+## Harness evidence
+
+The native portion of OHS-R01–R16 and decision 0006 belongs to the
+[observed-state, stop-ordering, diagnostics and delivery-input invariants](invariants.md)
+and [seat state authority](seat-state-truth.md). Only the owning driver, channel or
+hook publishes state. Missing evidence never proves idle. `unknown` is derived,
+freshness uses embedded time rather than mtime, and evidence loss stops
+heartbeats. A positively proved dead session can narrow a live observation; an
+indeterminate liveness probe cannot prove death. A terminal observation survives
+its writer, and stop escalation must preserve terminal evidence first.
+
+Diagnostic stages, reasons and sources have closed vocabularies. Missing,
+malformed, foreign and indeterminate records are distinct from healthy evidence.
+Recovery clears only its own stage. Admission failures outrank credential
+rejection, which outranks delivery/read-back symptoms. Credential rejection needs
+typed producer evidence; provider prose supplies no authority. The current
+[admission and repair policy](seat-deploys.md) owns current behavior, including
+explicit person-authored admission exceptions. Retired catalog roster commands
+and historical permission-downgrade proposals supply no current API contract.
+Bounded diagnostic telemetry belongs to [observability](observability.md).
+
+HC-R01–R18 and decision 0014's surviving numeric-context requirements belong to
+the [context, producer-arithmetic and status-line invariants](invariants.md).
+Each maintained harness supplies its own numerator, window and compaction facts,
+qualified by a version-pinned fixture. Unknown values stay absent, above-window
+values stay unclamped, and account totals do not become occupancy. Readings remain
+advisory and independent of categorical activity; stale values retain their age.
+Origin time owns freshness. Bucket changes, compaction and the named heartbeat
+bound writes; record updates must not wake their own delivery pump. Incarnation
+is provenance for numeric readings; the relaunch claim removes the predecessor's
+context. The status-line tee records and forwards exact input to the operator's
+renderer. Without a usable renderer, stdout stays empty rather than exposing the
+machine payload. These requirements do not retain the retired catalog's transport
+include list, roster wire format or Doctor interface.
+
+## Native channel and admission decisions
+
+Installed hook sets remain immutable and verified. Selecting a new set does not
+invalidate a set used by a running binary; the current upgrade and selection
+rules live in [seat deploys](seat-deploys.md). Restored session context uses the
+provider's model-visible contract rather than terminal inference. A residency
+resume must preserve the exact native session and refuse foreign or malformed
+checkpoints before binding or delivery, as described in [omp](omp.md). Durable
+mail waits for readiness rather than authorizing a replacement conversation.
+
+Decision 0005's pi extension and decision 0007's separate omp extension remain
+native transports. Rust owns delivery policy; extensions carry correlated frames.
+No screen classifier supplies native delivery readiness. A lost channel supplies
+no positive delivery or idle evidence. The current channel binding, checkpoint,
+observed-state and restart rules are in [seat deploys](seat-deploys.md),
+[harness access](harness-access.md), and [omp](omp.md).
+
+OMP-R01–R06 require its own shipped extension, positive post-`agent_end` idle
+evidence, correlated human-approval state, exact-build measured admission and
+typed credential classification. The complete maintained launch, admission,
+exception, native error and modal-hold contracts are in [omp](omp.md). Historical
+captures qualify only their named builds; they do not admit a new executable or
+extension. Codex's schema admission (R38) and the other native gates are described
+in [seat deploys](seat-deploys.md); schema compatibility alone proves no turn or
+receipt behavior.
+
+The rolling-release obligation R49 lives in
+[compatibility](compatibility.md#required-rolling-window), with its implementation
+gap explicitly open. DELTA-006 remains at its
+[migration deletion trigger](../vrs/.delta/DELTA-006-delivery-state-v1-arm.md), with
+both seven-day zero observations and a separate ratified rollback decision still
+required.
+
+## Historical provenance
+
+The retired VRS and captures remain readable at
+[main commit bb51bdcb0cd549b06c298d81c1907a7fd35f0c83](https://github.com/compoundingtech/fractal/tree/bb51bdcb0cd549b06c298d81c1907a7fd35f0c83/docs/vrs).
+Source comments that cite measured harness captures use that same immutable
+commit. Embedded omp hook files keep their original bytes, including relative
+historical citations; resolve those paths against this commit. This preserves
+their content-addressed hook identity while retaining the measurements' origin.

 a cached summary using an indexed query per locally owned recipient. Refresh

 Refreshes never overlap; after each refresh the worker pauses for at least 30 seconds, or
 the refresh's elapsed duration if longer. SDK collection reads only the cached
 summary and advances ages from cached accepted timestamps; it does no store,
 graph or filesystem reads. Counts and membership therefore reflect the last
 successful refresh rather than the instant of collection.
+Bands are classified only at refresh time with one shared `now`. A message crosses
+bands at the next successful refresh, normally at most about 30 seconds late
+(long refreshes or failures can delay this). Scraping advances ages but does not
+reclassify cached messages, so a recent-band age can briefly exceed one day.
 Failed refreshes retain the last complete summary and log a warning.

 the reasons live in the daemon's memory, as the envelope queue's do; a daemon restart rebuilds them
 from the next pass. `builds.slice` keeps its own cap and admission and is not counted.
 
+## Bursts
+
+A seat's base lane is sized for its harness thinking, not for its builds; a command that builds asks
+for a burst, its seat's lane raised for that command's run alone:
+
+```
+fractal agents burst AGENT --cores 8 --memory 24G --reason st-test --as AGENT
+```
+
+The command is the holder. It asks the daemon on the seat's host, prints one line per answer
+(`waiting REASON` each time the reason changes, then `granted CORES MEMORY`; or `none WHY` when
+the seat holds no lane there, lanes are off, or the daemon has no bursts; or `refused WHY` for a
+burst that can never fit), and then holds the burst while its standard input stays open, renewing
+a 90-second lease every 30 seconds. It gives the burst back when its input closes: when the run that
+started it ends, however it ends. A holder killed outright stops renewing, and the daemon drops the
+burst when its lease lapses; each such drop is counted (`bursts dropped by lease` in
+`st doctor --performance`), so a holder that crashes shows. The actor must be the seat itself, and
+only the seat's own host answers. While that daemon cannot be reached (a restart), the holder waits
+for it as it waits for room, saying so, rather than answering: the run that asked bounds the wait.
+
+The live lane is the largest, in each dimension, of the seat's own lane, each step it holds and its
+burst. A burst fits as a step's raise does: the raised lane must fit the host's room for lanes
+beside the other lanes and what seats outside lanes hold. Bursts wait in the order they asked, so a
+small one does not pass the first in line; one larger than the host can ever give is refused at
+once. A seat that has waited 15 minutes or more to start, first in line for room, is served before
+more bursts: a new burst waits behind it, so a stream of bursts cannot keep it from starting. It
+does so only while that seat would fit once every step's raise and burst on the host were given
+back; one that waits for another seat to stop gains nothing from it, so bursts go on beside it. A
+waiting burst's reason starts `burst lane`. While held, admission counts the seat at the raised
+lane. Released, its cores come back at once and its memory once the lane holds less than it
+will allow, as a step's lowering does. Bursts live in the daemon's memory: after a daemon restart
+the slice is still raised and counts, as any raise does, and the holder's next renewal holds it
+again.
+
+A burst is tied to the command, not to a step, so a seat in `work wait` holds only its base and
+its steps. A seat without a lane, or a host with lanes off, holds no burst: the holder answers
+`none`.
+
+`scripts/fractal-test` asks for one before it takes a pool tree (a tree held while its run waits
+for room is a tree nobody can use), sized by `.st/lane-bursts.json` for a run that builds (any
+check in `BUILDS`); a run that builds nothing asks for none. It waits up to `--queue-limit`, prints
+each reason, and records `burst` (the size held, or none and why) and `burst_wait_s` in the run's
+`runs.jsonl` line, which `scripts/fractal-test-report` shows as its own line beside the tree and
+slot waits. A fractal or daemon without bursts holds none, says so, and the checks run in the lane
+as it is. Its compiles still go to the host's sccache server in `builds.slice` (above): the burst
+bounds the rest of the run.
+
 ## Later steps (decided, not built)
 
-- **Bursts.** A heavy command asks for a burst; `st-test` asks for one sized to the checks it will
-  run (covered checks skip, a docs-only run needs almost nothing). A burst raises the live scope
-  with `systemctl --user set-property --runtime` and lowers it when the command ends. A step may
-  adjust the base. A seat in `work wait` holds only its base.
 - **Placement.** A mission that pins no host runs on a member with room for it: see
   [lane-placement.md](lane-placement.md).
 - **Starvation.** Waiters already wait in order, so the host drains to fit for the first in line

-# DING harness dispatch is positional, and each harness owns its own vocabulary
-
-Status: accepted
-
-## Context
-
-DING classified a screen by asking, in a fixed order, whether it looked like one
-maintained harness and then the other, and it applied one shared active-turn and
-modal predicate to every harness. Both choices were sound while the classifier
-was small. Both produced defects once a real fleet ran against it.
-
-Ordered dispatch has no way to express *which composer will receive the
-keystrokes*. It answers "does this screen contain harness X" when the safety
-question is "what will this pane do with input". A shared blocked-predicate has
-the same shape of error one level down: it lets one harness's rendering decide
-another harness's safety gate.
-
-Splitting the implementation into one module per harness forced the question,
-because a module boundary has to be drawn somewhere, and the wrong boundary
-would have preserved both defects behind a tidier layout.
-
-## Evidence and Argument
-
-Three independent forms, none of which is reasoning alone:
-
-- **Implementation fact.** The shared active-turn predicate contains literals
-  drawn from one harness's rendering — plan prompts, capacity notices, retry
-  hints — and applies them to every pane. It also *omitted* that harness's
-  animated progress line, which does not always carry an interrupt hint. The
-  omission is only invisible while a separate parse defect keeps such screens
-  unclassifiable; removing that defect makes a mid-turn pane satisfy both the
-  idle and empty proofs.
-- **Independent critique.** An automated review of the change that reordered the
-  two harness checks identified the transcript case: a pane whose scrollback
-  contains a captured screen from another harness would be classified on that
-  scrollback rather than on its own live composer, admitting a paste — or a
-  Return — into a human's draft. This was found by an adversarial reader, not by
-  the change's author.
-- **Implementation fact.** The two harnesses do not match against the same
-  representation. One locates its composer in the raw screen including escape
-  sequences, yielding a byte offset; the other locates against ANSI-stripped
-  lines, yielding a line index. Any positional rule must therefore normalize to
-  a common unit, which an ordered chain never had to confront and which a naive
-  positional comparison would get silently wrong.
-
-## Options
-
-| Option | Tradeoffs |
-| --- | --- |
-| Keep ordered dispatch, special-case the transcript screen | Smallest change. The rule has to be written for each pair of harnesses, so it grows quadratically, and the next harness reopens the same class of defect. Does not address the shared predicate. |
-| Reverse the order instead | Trades one wrong answer for another: it restores the original defect, where a used pane of the first harness is unclassifiable, from the opposite side. |
-| Positional dispatch over a harness registry, with per-harness vocabulary | Requires an interface, a position type, and a unit conversion that did not previously exist. Duplicates some near-identical interrupt literals across harnesses. Makes the transcript case structural rather than special-cased, and confines each harness's rendering to its own safety gate. |
-
-## Decision
-
-Positional dispatch over a registry, with each harness owning its composer
-markers, footer chrome, idle proof, and active-turn and modal detection.
-
-Every registered harness is asked to locate a composer; the one lowest on the
-screen is classified. This is correct by construction rather than by
-enumeration: scrollback is above the live composer, so the composer that will
-receive the keystrokes is the lowest one, whatever a transcript happens to
-contain. Positions are normalized to a screen row before comparison, because the
-harnesses report incomparable units.
-
-Shared code keeps only what is genuinely common to every harness. The duplicated
-interrupt literals are accepted cost: a shared vocabulary is what let one
-harness's strings, and one harness's omissions, silently govern another's panes.
-
-## Consequences
-
-- Adding a harness is a new module and a registry entry; it does not edit shared
-  classification. This is the property that keeps the transcript defect from
-  recurring per pair.
-- Widening what counts as blocked remains always-safe and may be done per
-  harness. Widening what counts as idle requires evidence from a real screen —
-  a rule this decision does not relax.
-- The requirements this pins are `DING-R04` and `DING-R06` in
-  [`../01-ding/requirements.md`](../01-ding/requirements.md).

-# Stable agent identity is separate from mutable presentation
-
-Status: superseded by 0015-immutable-agent-id-and-mutable-address
-
-Johannes authorized the requirements direction on 2026-07-31. The draft
-required Alex's merge and acceptance approval, which was not recorded.
-Decision 0015-immutable-agent-id-and-mutable-address independently accepted the replacement contract.
-
-## Context
-
-Agent Spec currently overloads one identity string as both an automation key
-and the only human recognition surface. Operators cannot improve a label
-without changing routing, durable paths, task identity, and process lifecycle.
-An experimental sibling `name` file is a second source of truth and does not
-compose with canonical Agent Spec authoring.
-
-The fleet requires a stable automation identity and presentation that can
-change while the running process, PTY generation, bus, and durable state remain
-continuous. The change must not introduce a stable-ID alias, dual parser, or
-long-lived migration branch.
-
-## Decision
-
-The existing positional Agent Spec identity remains the sole stable automation
-ID. Its grammar and the established `identity` JSON/TOML/roster spelling remain
-unchanged. There is no stable-ID rename operation.
-
-Agent Spec adds direct optional `name` and `description` fields. They are
-non-authoritative, non-unique presentation. Omission means absence. The Agent
-Spec declaration is their sole source of truth; a sibling `name` file is neither
-read nor written.
-
-Constrained KDL-only commands may mutate one presentation field without
-accepting a second authored representation. Within the trusted-fleet model,
-caller-supplied `ST_AGENT` limits an invocation to itself or declared
-descendants; this is an operational guardrail, not an authenticated capability,
-and absence selects the operator path. Declarations explicitly marked Nix-owned
-remain writable only at their Nix source, and Nix emitters must publish that
-marker before authoring is activated. st2 serializes these
-edits with the shared persistent `.st2/catalog-authoring.lock`, preserves
-unrelated source bytes, detects stale source, and atomically replaces the
-declaration. The lock covers cooperating local st2 writers in one POSIX
-filesystem/kernel lock domain; it does not claim exclusion across independently
-synchronized hosts or direct external writers.
-
-Healthy runtime reconciliation uses the atomic exact-ID-only `pty metadata
-patch --id <task-id>` operation. It projects name to native PTY `displayName`
-and a versioned st2-owned tag snapshot containing stable actor identity plus
-optional description. Name is not duplicated in tags. One real patch emits one
-coherent `metadata_change` event; an unchanged patch emits none. Automation
-never uses human display-name resolution. Presentation drift degrades and
-retries without restart or lifecycle accounting.
-
-Harness drivers consume the current lowered Agent Spec rather than a second derived
-presentation file. In-process drivers may read the lowered `AgentSpec` directly;
-external hooks or drivers may select the exact qualified stable identity through
-`st2 agents --identity <host>.<identity> --json`. The roster query returns
-exactly one row or fails and keeps nullable name and description separate from
-stable identity. Provider-native translation and exact session fencing remain
-driver responsibilities; this read interface grants no lifecycle authority.
-
-## Consequences
-
-- Human labels can improve without breaking routing or continuity.
-- Duplicate or absent names are valid; stable IDs remain visible for exact
-  disambiguation and automation.
-- The old equality between stable identity and every presentation surface is
-  superseded, but stable routing semantics are preserved.
-- Existing declarations require no presentation compatibility marker because
-  the new fields are optional and additive. Adoption begins only after
-  compatible PTY and st2 binaries are deployed; Nix-generated declarations
-  first add their ownership marker.
-- Decision 0015-immutable-agent-id-and-mutable-address superseded this unaccepted draft and independently accepted the
-  presentation behavior it retained.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Stable identity plus direct `name` and `description` | Selected | Added mutable presentation without changing routing, task identity, or durable state. |
-| Sibling mutable `name` file | Rejected | Created a second source of truth outside canonical Agent Spec authoring. |
-| Rename the stable identity | Rejected | Disconnected routing and continuity and had no proved state migration. |
-
-## Evidence and Argument
-
-PTY already separated immutable native session ID from mutable display metadata
-and provided one atomic exact-ID metadata patch. The st2 parser, roster,
-source-preserving authoring, authority, and no-restart reconciliation proofs
-listed below established that direct presentation fields compose with the
-existing runtime without changing task incarnation or durable state.
-
-## Amendment 1 — immutable subject ID and mutable address
-
-Accepted decision 0015-immutable-agent-id-and-mutable-address supersedes this draft's routing model and independently
-accepts its bounded presentation and authoring behavior. The target adds an
-explicit immutable `id`; legacy subjects receive their existing host-qualified
-bus identities as IDs during migration. Positional `identity` remains the
-legacy address fallback. Agent ID is catalog-global; agent address is mutable
-and unique per logical host; bus address is `<host>.<address>`. Exact ID
-selection is explicit.
-
-Decision 0015-immutable-agent-id-and-mutable-address also independently accepts nondisruptive PTY presentation
-projection. Its rejection of a stable-ID alias remains: address is a mutable
-route to the subject, not a second stable ID, and old addresses receive no
-redirect or history.
-
-## Evidence proposed by the draft
-
-The unaccepted draft proposed:
-
-- parser and roster tests across KDL, TOML, and JSON;
-- source-preservation, authority, Nix refusal, and stale-writer tests;
-- exact-ID PTY projection tests for set, clear, idempotence, and partial failure;
-- exact ID roster selection, nullable values, absent-ID refusal, and co-located
-  declaration tests;
-- a live no-restart test preserving stable task ID, PID, creation identity, and
-  generation across Agent Spec presentation changes;
-- a genuine lifecycle-change control that still performs ordinary replacement.
-
-Decision 0015-immutable-agent-id-and-mutable-address carries the accepted proof obligations.

-# Typed agent desired state separates reversible suspension from retirement
-
-Status: accepted
-
-Requirements change authorized by Johannes on 2026-08-04.
-
-Merge and acceptance approval required: upstream maintainers
-
-## Context
-
-Agent Spec has one irreversible-looking `retired` boolean. Operators sometimes
-need to keep an agent discoverable and addressable while intentionally running
-none of its tasks. Removing or commenting out its declaration loses catalog
-intent; overloading `keep`, task `lifecycle`, presence, or runtime pause would
-conflate independent contracts. A bare boolean also cannot explain why an
-agent is unavailable.
-
-## Decision
-
-Agent Spec uses one typed whole-agent desired state: running, suspended, or
-retired. Running is the omitted default. Suspended and new retired declarations
-carry a bounded human rationale. The parser retains legacy `retired #true` as
-retired without a rationale and rejects every declaration that combines old
-and new lifecycle syntax.
-
-Suspension and retirement both desire no live owned tasks, including generated
-companions. Suspension remains reversible, preserves catalog-backed durable
-state, and permits dead records only when existing `keep` policy explicitly
-pins them. Retirement keeps the established stronger completion rule: every
-declared task record is absent. Returning to running uses ordinary
-reconciliation and does not override `keep`, `adopt-only`, drift, or ownership
-proof.
-
-The KDL-only authoring command edits one exact declaration through the existing
-catalog-authoring transaction. Running removes lifecycle syntax; the other
-states use `desired-state "..." reason="..."`. The receipt proves only that
-the declaration was durably authored. Roster, inventory, human listing, and
-Doctor expose desired intent separately from presence and observed liveness.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Keep `retired` plus an implicit suspension field | Rejected | Leaves invalid combinations and no closed lifecycle model. |
-| Add independent `suspended` and `retired` booleans | Rejected | Creates four source combinations for three states and makes precedence part of every consumer. |
-| Use one closed desired-state enum with a rationale and legacy retirement read path | Selected | Makes illegal combinations unrepresentable in the normalized model and preserves compatibility. |
-
-## Evidence and Argument
-
-The independent bounded oracle passed all 9 validity and 36 planning cases.
-The real-path prototype then proved the selected model through parsing,
-source-preserving authoring, reconciliation, PTY and exec backends, a generated
-DING, message retention, task inventory, roster, and cleanup. It exposed one
-necessary distinction: suspension converges at no-live plus only keep-pinned
-dead records, while retirement converges only at total record absence. The same
-run showed that resume needs no new runtime mechanism; ordinary reconcile
-already preserves keep and adopt-only semantics.
-
-## Consequences
-
-- One enum owns lifecycle intent; suspension does not introduce another runtime
-  state machine.
-- Existing declarations continue to parse, and legacy retirement stays visible
-  through the compatibility `retired` projection.
-- DING stops while suspended, but inbox and other durable state remain
-  addressable and resume unchanged.
-- Consumers that need the rationale use the new desired-state fields rather
-  than presence or the legacy retirement projection.
-- Nix-owned declarations remain editable only through their Nix source.
-
-## Evidence required for acceptance
-
-- exhaustive state/reason parser controls and legacy compatibility;
-- reconcile matrices for alive, absent, dead, keep, adopt-only, derived, remote,
-  resume, and retirement controls;
-- source-preserving CLI, authority, stale-writer, malformed, and Nix refusal
-  tests;
-- Doctor and machine-wire tests distinguishing suspension from retirement;
-- a live PTY plus exec companion suspend/resume run that preserves a sibling
-  generation and an inbox message.

-# Stream events are a distinct record kind on the shared bus transport
-
-Status: accepted
-
-Design decision made by Johannes on 2026-08-20 (interview over four executable
-prototypes). Merge and acceptance approval required: upstream maintainers, per
-the DQ1 approval loop noted in [issue #137](https://github.com/compoundingtech/st2/issues/137).
-
-## Context
-
-Agents need to subscribe to external-world changes (CI runs, PRs, timers,
-monitoring) and be woken with each change through existing message delivery.
-Issue #137 fixed the ingress contract: one external event becomes exactly one
-durable inbox item, deduplicated by a producer-supplied identity, waking the
-recipient through the normal inbox path.
-
-Three overlapping mechanisms could carry such an event: ordinary agent→agent
-messages (durable sender ledger, `(sender, recipient, key)` idempotency),
-service-principal requests (`request.rs`: typed envelopes, reserved-filename
-idempotency, no ledger), or a new record kind. Two e2e prototypes and two
-independent design explorations (unification pole vs differentiation pole)
-were built to decide; their reports live in
-[`04-stream/.experiments/`](../04-stream/.experiments/).
-
-## Decision
-
-An **event** is a second record kind on the one existing transport. It is an
-ordinary inbox message file — same filename grammar, same inbox/archive
-directories, same DING/MCP/app-server delivery, no new notice path — carrying
-event frontmatter: the producing stream, a mandatory producer-supplied
-`event-id`, and an optional grouping `key`.
-
-Event publication does not write the permanent hash-chained Agent Sent ledger.
-Dedup state is a bounded, constant-size receipt ring plus one in-flight
-publication reservation per stream. The reservation includes the full
-rendered-content digest, supersession intent, and exact predecessor receipt (or
-none) selected from the ring; final receipts retain those semantics too.
-Replaying an `event-id` within the retained receipt horizon returns the
-original filename and never re-notifies only when content and supersession
-intent match. The next emit reconciles an abandoned reservation only after its
-materialized event identity and full bytes match, then validates and moves the
-exact stored predecessor inode before completing compaction. An authenticated
-same-name archive receipt is the only proof that an inbox-absent predecessor
-already moved; absence from both fails closed. Successor bytes and their inbox
-directory are fsynced before the final receipt commit. Recovery requires
-neither stale producer replay nor retained payload bytes.
-An evicted identity is accepted as new without scanning inbox or archive
-history; archive receipts keep their existing authority for known filenames.
-An emit may declare `--supersede`, which publishes the successor before
-archiving the newest matching retained predecessor that is present in inbox
-and absent from archive. Both initial publication and recovery validate that
-predecessor's no-follow bytes and parsed identity against its retained receipt
-immediately before the move — log-compaction semantics with bounded lookup and
-a duplicate-wakeup rather than lost-wakeup crash bias — implemented
-producer-side only; DING's staged ownership is never touched.
-
-Ordinary messages and `MESSAGE-R01..R11` are unchanged. The typed
-service-principal request/reply envelopes are absorbed over time: a reply to
-an event is an ordinary `message reply`, and the `pending | replied` status
-derives from `in-reply-to`. Retirement is conditional on defining and proving
-a routable reply endpoint for the stream producer; a stream-qualified `from`
-identity is not by itself such an endpoint.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| One record family, one ledger: everything is a message with a `kind` frontmatter discriminator, every producer writes the sender ledger | Rejected | The ledger answers "prove what this agent said" — a question no machine producer has. CI flaps would enter permanent O(history)-validated history, supersession and bounded retention are incoherent inside an append-only proof chain, and the pole's own report conceded a "keys-only profile" (re-splitting the store) for high-volume sources. |
-| Two record kinds, one transport: events carry stream identity, supersession, and a bounded dedup ring; messages stay untouched | Selected | The extra semantics are measured needs, and the option still captures the poles' converged 80%: two identity kinds, requests absorbed, one transport and delivery path, fan-out fixed by scoping dedup per recipient. |
-| Stream semantics as `message send` flags: one verb whose `--stream` presence flips ledger semantics to ring semantics | Rejected | A second mechanism wearing the first one's name; the divergent durable behavior hides behind a flag instead of a kind. |
-
-## Evidence and Argument
-
-Two independent design explorations were built from opposite poles, each with
-an executable spike of its riskiest seam
-([`04-stream/.experiments/`](../04-stream/.experiments/)). The unification
-spike proved a non-agent sender can survive crash injection at all nine
-publication checkpoints of the ledger transaction — so safety does not decide
-the question. The differentiation spike proved the semantics only its model
-offers: producer-side supersession never re-pastes a DING-staged predecessor
-(24 supersedes in 146 ms → one fresh poke, zero staged retries, one unread
-head), stream state stays constant-size, and R15 boundedness holds under a
-fast-superseding stream. The earlier ingress prototype had already shown the
-ordinary-message path cannot express a non-agent producer and writes one Agent
-Sent row per event against MESSAGE-R11. The decisive argument is fit: a ledger
-built to prove speech misfits facts that supersede each other, and both poles'
-reports agreed on that sentence from opposite directions.
-
-## Consequences
-
-- The DING sidecar gains exactly one branch: the `»` glyph for events.
-  Everything else in the fail-closed DING contract is inherited untouched.
-- `request.rs`'s wire types carry `deny_unknown_fields` and cannot evolve in
-  place; absorption therefore uses the fresh-namespace pattern with a
-  deprecation window, and its dedup receipts are retired, not migrated.
-- A restarted stream has no cursor; it re-observes current state and leans on
-  the dedup ring. Catch-up history is explicitly not a v1 capability.

-# pi delivers natively through an st2-injected extension, and never through DING
-
-Status: accepted
-
-## Context
-
-st2's two maintained harnesses reach a live interactive session in two different, expensive ways.
-Claude gets an MCP stdio child plus an outer wrapper that owns presence because Claude may close
-that child, plus lifecycle hooks, plus a batched mutation of the operator's ambient config to clear
-the workspace-trust dialog. Codex gets a dedicated app-server daemon, an observer connection opened
-before the interactive client, thread-ownership binding, and a hard version pin — 4940 lines.
-Underneath both sits DING, the screen-scraping transport that exists because neither harness offered
-anything better at the time, and whose safety rests on a synchronous adjacent composer proof
-([`0001-ding-harness-dispatch-is-positional-and-harness-owned`](0001-ding-harness-dispatch-is-positional-and-harness-owned.md)).
-
-Adding pi asks which of these shapes it should take. pi answers the question itself: it has no MCP,
-no app-server, and no lifecycle-hook mechanism. What it has is an extension API that runs **inside**
-the interactive process.
-
-## Evidence and Argument
-
-Measured on `@earendil-works/pi-coding-agent` 0.84.2 against a local fake provider, so every run is
-reproducible with no credentials. Full record and captures:
-[`../.experiments/2026-08-18-pi-harness-integration.md`](../.experiments/2026-08-18-pi-harness-integration.md).
-
-- **The delivery path is evented, not observed.** An out-of-process inbox drop reached a live
-  interactive TUI and drove a complete model turn in 58 ms: `fs.watch` → `sendUserMessage` in the
-  same millisecond, `agent_start` one millisecond later, `agent_settled` 57 ms after that. Nothing
-  inspected a screen.
-- **Mid-turn delivery is a typed queue, not a race.** Dropped while `isIdle()` was false, the message
-  was accepted immediately and became its own turn in the same millisecond the running turn ended.
-  This is the case DING can only defer and retry.
-- **The idle proof is positive and in-process.** `ctx.isIdle()` is false for exactly the span
-  `agent_start`..`agent_end`. Compare the defect the prior research found in the PTY observer, where
-  a Claude pane proves idle exactly once and is unprovable forever after.
-- **A modal does not corrupt delivery — and this was the case most likely to sink the design.** With
-  pi's `/model` picker open, `isIdle()` reads true, the message is delivered, a full turn runs, and
-  the human's modal is untouched; dismissing it reveals the exchange in the transcript. This is the
-  pi analogue of the Codex defect where `activeFlags: waitingOnApproval` is discarded and st2 steers
-  into an open approval dialog, and pi does not reproduce it.
-- **The production configuration was run, not assumed.** With the host's three ambient global pi
-  extensions left enabled and st2's channel merely added with `-e`, all five loaded and delivery
-  behaved identically.
-- **The composer offers nothing to scrape.** pi renders a full-width `─` rule, the editor line, and a
-  second rule. There is no Codex-style ANSI composer marker and no Claude-style prompt glyph.
-  [`0001`](0001-ding-harness-dispatch-is-positional-and-harness-owned.md) requires evidence from a
-  real screen before widening what counts as idle; this screen supplies none.
-- **pi buys nothing on death.** SIGTERM emits `session_shutdown` — better than Claude, which emits
-  nothing — but SIGKILL is silent, exactly as for Claude. Presence still needs an owner and still
-  decays by staleness.
-- **The trust dialog is real and cheap to clear.** A workspace with `.pi/settings.json` renders a
-  blocking modal during which *no extension event fires at all*, not even `session_start`. `pi -a`
-  clears it for that run and writes nothing to `~/.pi/agent/trust.json`.
-
-## Options
-
-| Option | Tradeoffs |
-| --- | --- |
-| A pi DING adapter, like the incumbents' fallback | Reuses the shipped transport and needs no new process. But the composer has no marker to key on, so the idle proof would rest on generic rules — the exact widening `0001` refuses without screen evidence — and it would forgo an evented channel that already exists and measures better. |
-| RPC mode (`pi --mode rpc`) as the channel | A documented protocol st2 could speak directly. It *replaces* the TUI, so the human-visible pane under `pty` that st2's whole model assumes would be gone. This is the Codex problem — needing a second connection because the interactive client is opaque — reintroduced by choice. |
-| An extension st2 injects, talking to an st2-owned channel process | Requires a new wrapper, a new stdio protocol, and shipping a TypeScript asset in an otherwise Rust binary. In exchange the injection point is a documented API call, the idle proof is in-process, and no screen is ever parsed. |
-
-## Decision
-
-pi is a natively-delivered harness. It declares `deliver "pi-channel"` or a typed `pi {}` driver,
-and **no pi arm is added to the DING registry**. The existing rule that refuses `ding` together with
-`deliver` (`crates/agent-spec/src/spec.rs`) is what keeps a pi agent off the PTY write path
-entirely, so [`0001-ding-harness-dispatch-is-positional-and-harness-owned`](0001-ding-harness-dispatch-is-positional-and-harness-owned.md) is untouched.
-
-Four things follow, each chosen against a specific failure it prevents:
-
-1. **st2 injects the extension; the declaration never names it.** `st2 driver pi-session` resolves
-   `pi-channel.ts` from this binary's *verified* immutable set and splices `-e <path>` into the
-   provider argv at launch. A path written into the declaration would pin one host's layout into a
-   catalog, and an `$ST_HOOKS` token in an argv would resolve to the receipt-bearing root rather
-   than the selected set. The asset ships inside the same content-addressed hook set as the Codex
-   and Claude lifecycle scripts, because for pi an extension *is* the hook mechanism.
-2. **The extension holds no policy.** It moves frames. st2 decides which message is delivered and
-   how; `deliverAs` travels on the frame, so changing delivery behaviour is a Rust change and not a
-   redeploy of a TypeScript asset. The initial value is `steer` — the earliest point pi accepts
-   input without discarding the running turn, and the same choice the Codex native path makes.
-   Per-message selection between steer and queue is #277. Measured live, `steer` is a stronger
-   guarantee than its own description: the delivery boundary is a single tool call, not the whole
-   job, so a message sent mid-job waits only out the in-flight call rather than the work remaining. The same rule governs session start:
-   pi has no session-start hook, so what a restarting agent is told is composed in Rust
-   (`session_context`) with the Codex hook's exact blocks and order, and rides the `hello` frame.
-   The extension awaits that frame inside `session_start`, which is what puts restored context in
-   the boot turn rather than the turn after it.
-3. **The wrapper owns presence, as it does for Claude.** The extension lives only as long as pi's
-   process and SIGKILL is silent, so nothing in-process can be the liveness authority. The wrapper
-   also exports its own executable path: resolving `st2` from `PATH` inside the extension would let
-   a replaced control plane and its live agents disagree, which is what **R11 control-plane
-   replacement safety** exists to prevent.
-4. **Trust is a launch flag, not a config mutation.** Expansion emits `pi -a`. There is no pi
-   analogue of `src/pretrust.rs`, and therefore no pi analogue of the multi-spawn lost-update race
-   that forced trust writes to be batched before the first Claude boot.
-5. **A managed seat is offline and does not leak its identity downward.** The wrapper sets
-   `PI_OFFLINE=1` and `PI_SKIP_VERSION_CHECK=1` where the operator declared nothing, so a supervised
-   agent does not self-update or make boot latency depend on the network. The extension unexports
-   `ST2_PI_CHANNEL_*` after reading it, because pi puts its environment in front of every tool
-   child; measured, a nested child now sees none of them while pi's own `PI_*` still reaches it,
-   which is why the eval seat scrub gains `PI_*` beside `CLAUDE_*`/`CODEX_*`.
-
-## Consequences
-
-- pi is the first harness whose delivery never touches a PTY. **Fail-closed observed native DING**
-  and **Bounded DING PTY probe churn** are unaffected — nothing here reaches the phase they govern.
-- **Agent-declared presence** gains a third wrapper. The row's wording names the Codex and Claude
-  wrappers specifically and now needs pi beside them; the guarantee itself is unchanged, and
-  `src/pi_session.rs::idle_pi_provider_refreshes_presence_without_channel_input` proves it.
-- A pi agent whose extension fails to load is *unreachable but visible*: presence still decays, so it
-  reads as stale rather than as a healthy agent silently dropping mail. This is deliberate. The
-  alternative — a wrapper that keeps presence fresh regardless — would make presence lie.
-- Adding `pi-channel.ts` to the hook set changes the hookset hash, so every host must run
-  `st2 hooks install` to select a set that contains it. `st2 driver pi-session` refuses to launch
-  against a set that does not, naming the command.
-- st2 now ships a TypeScript asset. It is small, holds no policy, and is content-addressed and
-  verified like every other file in the set — but it is a genuinely new kind of artifact in this
-  repo and a second language to keep working.
-- The extension reports `delivered` and `failed` back on the channel, but st2 does not yet act on
-  either: the channel marks a filename delivered when it writes the frame, exactly as the Claude MCP
-  channel does, so a `sendUserMessage` that throws is not retried until the channel restarts and
-  rescans the inbox. This is parity with the incumbent, not a property of the new design, and the
-  ack frames exist so it can be closed without a wire change.
-- **pi gets no version pin, because pi publishes no version to pin.** It ships no changelog, no
-  stability policy, no compat field, and no extension-API version constant. What it does publish is
-  its TypeScript declarations, and those are the artifact that actually governs this coupling — so
-  that is what st2 checks. `checks.pi-extension-types` type-checks `hooks/pi-channel.ts` against a
-  pinned pi release at build time.
-
-  This follows st2's existing rule rather than inventing one. The repo pins where skew fails
-  *silently*: `pty`, whose old builds ignore `--unset-env` and leave a launch looking correct;
-  `codex-cli`, whose untyped app-server wire misparses quietly. It does not pin Claude, whose
-  failures are loud. The pi extension had exactly one silent surface — `ctx.isIdle?.() ?? true` read
-  a missing idle proof as "idle", which would have turned every mid-turn delivery into a plain send
-  — and the check catches precisely that: using the idle proof as a property rather than calling it
-  is a type error (`TS2774`), demonstrated failing in the Nix build.
-
-  The rate is measured, not assumed. Across pi 0.74.0..0.84.2 (41 releases, 40 transitions) the
-  whole `types.d.ts` changed in 17 transitions, while the surface this extension depends on changed
-  in **one**, additively (`expandPromptTemplates?` added to `sendUserMessage`). So the check is
-  close to noise-free while still refusing a real removal.
-
-  Cost, stated plainly: the check fetches pi's npm tarball (~145 MB unpacked) and `@types/node`, and
-  runs `tsc`. It is a separate check derivation, not part of the main build, and it is pinned by
-  tarball hash rather than an npm lockfile because pi bundles its sibling packages without integrity
-  hashes, which `fetchNpmDeps` cannot express. Moving to a newer pi is a deliberate edit of that pin
-  — which is the point.
-- The st2-owned channel wire carries its own protocol number that the extension refuses on mismatch.
-  That covers st2-side drift and is independent of the above.
-
-## Evidence required before this is load-bearing
-
-- ~~one live-provider run~~ — **done**, and it strengthened rather than weakened the design: the
-  steer boundary is one tool call rather than one job, and session restore was proven with a nonce
-  the model read back. It also established that the restored ritual only works when the shipped bus
-  contract (`templates/bus.st2.md`) is in the workspace, which the maintained pi example now
-  requires. Compaction remains unexercised;
-- a located blocked-on-human state. pi's permission gating is extension-implemented, so the Codex
-  `activeFlags` analogue has not been found, and the one blocking state measured — the trust
-  modal — is invisible to extensions;
-- an end-to-end run against a real catalog, which the unit-level proofs here do not replace.

-# Streams are agent-nested declarations, and "stream" anchors the vocabulary
-
-Status: accepted
-
-Design decision made by Johannes on 2026-08-20 (interview over four executable
-prototypes; vocabulary designed against Kafka/Unix prior art and the existing
-ontology). Merge and acceptance approval required: upstream maintainers.
-
-## Context
-
-A subscription that turns external-world changes into inbox events needs a
-declaration site and a name. The lifecycle prototype nested a `pipe` node
-inside the agent; both design explorations independently placed a top-level
-producer declaration beside agents (`sources/` / `principals/`) for
-identity-grammar reasons, and both flagged the locality as a human call. The
-working name "pipes" came from the branch, `pipe` from Unix and the Claude
-Code Monitor lineage; issue #137 left the command name deliberately open.
-
-## Decision
-
-The declaration is **agent-nested**: `agent { stream "gh-ci" { command … } }`.
-The subscription is visible on its subscriber, the recipient is implicitly the
-owner, lifecycle coupling is the already-proven derived-companion behavior
-(launch with the agent; stop on suspend, retire, park), and an agent
-self-subscribes by editing its own declaration through the existing serialized
-catalog-authoring path — R25's self/descendant authority covers it unchanged.
-Because the stream belongs to its agent, no non-agent identity is introduced
-and R10 survives untouched.
-
-The vocabulary is **stream-centric**: *stream* (the named declared event
-producer feeding an agent), *event* (one item on a stream), *key* (optional
-grouping axis; supersession collapses unread events per `(stream, key)` — the
-borrowed intuition is Kafka log compaction), *event-id* (producer-supplied
-dedup identity), *adapter* (the world-specific program a stream runs), and
-*stream task* (the derived companion, an implementation-level follower). A
-stream declared with either `command` or `argv` runs that adapter as a
-supervised stream task. Only a stream with neither adapter form is an external
-ingress endpoint: outside producers emit into it via `st2 event emit`, which
-natively covers issue #137's bootstrap-timer case. "pipe" is retired as a
-working title. Self-authoring exposes the same choice as mutually exclusive
-`--command <shell>` and direct `-- <program> [<arg>...]` forms.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Agent-nested declaration: `agent { stream "…" { command … } }` or `argv …` | Selected | The subscription is visible on its subscriber, lifecycle coupling is the proven derived-companion behavior, and self-authoring stays inside R25's existing authority. Accepted cost: two agents watching one feed run two adapters until a top-level generalization exists. |
-| Top-level `source` declarations beside agents | Rejected for v1 | An agent's declaration no longer shows what can wake it, self-subscription becomes authoring a foreign declaration outside R25, and subscriber lifecycle coupling was the one part neither design spike built. Reserved as the future shared-feed generalization. |
-| *pipe*-anchored vocabulary | Rejected | Unix "pipe" connotes a byte transport between two processes, not a durable deduplicated feed, and it forces two anchor-weight words for one family. |
-| *source*-anchored vocabulary | Rejected | Producer-perspective ("the agent's sources" says where events come from, not that they flow to you) and collides subtly with R13's "source" classification axis. |
-
-## Evidence and Argument
-
-The lifecycle prototype proved the nested form end to end: 27 tests over the
-derived-companion seam with zero changes to run, flapping, park, or task
-inventory, covering one-pass launch, suspend/retire teardown, independent
-parking with supervisor surfacing, and honest `st2 tasks --json`. Both design
-explorations specified top-level declarations but left subscriber lifecycle
-coupling unbuilt and flagged locality as a human call — so the only fully
-proven locality is the nested one. On vocabulary, the borrowed intuition
-decides: supersession per `(stream, key)` is exactly Kafka log compaction, a
-mental model operators already hold, while "pipe" and "source" each import a
-weaker or colliding intuition. The adapter-less stream unifies external
-ingress into the same concept, which lets issue #137's bootstrap-timer case
-run natively without a second producer-identity mechanism.
-
-## Consequences
-
-- Homograph to manage: R13–R15 use "event"/"event streams" for filesystem
-  watcher machinery. The ontology qualifies those as *watcher events*; future
-  requirements edits keep the qualification.
-- Issue #49's "topic" remains a message-side axis; the event-side grouping
-  axis is *key*. The two must not be merged by name.
-- Suspension semantics follow locality: the stream task is an owned task, so
-  R41 tears it down with the agent — eyes closed, no accumulation, resume
-  re-observes; the dedup ring makes re-emission of still-current state safe.
-- Ingress authority follows the same locality: `event emit` runs only when its
-  resolved logical owner host and catalog lock match the unsynchronized
-  machine-local binding established by the active supervisor. This supports
-  declared/`--host` logical aliases that differ from the OS hostname without
-  letting caller-controlled resolution grant authority. Synchronized remote
-  catalogs cannot publish; cross-host observations need an owner-domain
-  forwarding adapter/transport, which v1 does not provide.
-- Public removal is lifecycle-first: under catalog then exact-runtime
-  serialization, `stream rm` stops/retires an adapter companion and durably
-  proves process absence before publishing declaration removal. A failure
-  before source publish leaves the declaration intact for reconcile to
-  relaunch; adapter-less external ingress skips runtime teardown. Direct KDL
-  edits are not the self-authoring operation and carry no orphan-free promise.

-# Observed harness state is a driver-written catalog record
-
-Status: accepted
-
-Design decision made by Johannes on 2026-08-23 (interview over three research
-reports and issue #268, which carries the measurements cited below). Merge and
-acceptance approval required: upstream maintainers.
-
-## Context
-
-st2 exposes what an agent *declares* — presence, on a five-minute heartbeat
-with a fifteen-minute staleness horizon — and nothing about what its harness is
-*observed* doing. The one observed state machine that exists,
-`CodexObservedState`, persists host-local under `$XDG_STATE_HOME`, has zero
-production readers, and is invisible to the roster, Doctor, and every remote
-supervisor. Claude, pi, and OpenCode have no observed-state type at all. The
-concrete consumer is the one #261 and #268 name: a downstream TUI rendering a
-seat's working state, which today cannot distinguish "alive and doing nothing"
-from "recently active" because `lastActivity` advances on the agent's own
-heartbeat. #162 assigns provider-specific idle/active classification to
-drivers and keeps the generic envelope in core; this decision fills that
-envelope.
-
-## Decision
-
-Observed harness state is **one driver-written record in the catalog**,
-`<agent-dir>/harness-state`, schema `st2.harness-state.v1`, carrying the full
-tuple in v1: `state ∈ idle | active | child | ended` (`unknown` derived, never
-written; `child` reserved with no producer), **`blockedOn` as a field**
-(`human | none`), and `inputBuffer ∈ empty | nonempty | unknown`. The record
-follows the presence record's transport discipline — embedded origin
-timestamp, atomic tmp+rename, byte-distinct on every write — with its own
-staleness constants, deliberately not aliases of `status::STATUS_*`. Freshness
-is **transition writes plus a slow heartbeat** on the existing five-minute
-presence cadence, and a writer that loses sight of its harness stops
-heartbeating rather than refreshing a state it cannot see. **All four
-harnesses ship producers**: Codex projects its existing control state, Claude
-combines hooks with a wrapper-owned terminal write, pi exports the injected
-extension's positive idle signal as an evented producer, and OpenCode gains a
-full driver — session wrapper, presence lease, state producer, and a native
-delivery transport at parity with the other drivers. Exposure is **joined into
-`agents --json`** beside declared presence, plus a Doctor advisory. Teardown
-gets both fixes: the wrapper writes its terminal record *before* escalating
-SIGKILL into its own process group, and same-host readers cross-check the
-record's pty session, where only provable death downgrades. Transition history
-is deferred; `transitions` and `sinceMs` keep the record forward-compatible
-with it. The work proceeds without waiting on #242 and flags the delivery
-contract as that PR's territory.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Catalog record beside `status`, presence transport discipline | Selected | Remote supervisors and the TUI read through the catalog they already sync; the presence record's embedded-timestamp discipline is proven against transports that drop mtime. Accepted cost: a replicated write per state transition, unmeasured (OHS-T01). |
-| Host-local record plus CLI exposure only | Rejected | Zero transport cost, but remote readers get nothing and the consumer TUI must run on the owning host — the exact invisibility that leaves `control-state.json` unread today. |
-| Ride the stream/event ingress (#300) | Rejected | Events land in the inbox and DING the agent on every transition, emit is gated on a live owner binding and a healthy catalog, and stream direction is ingress into an agent, not egress about one. |
-| `blockedOn` as a fifth state | Rejected | An agent can be blocked while a child command runs; the field composes, a fifth state forces an ordering. A later-added axis would decode as `unknown` in every pinned v1 reader, so the field ships in v1 while the window is open. |
-| Sibling `st2 harness-state --json` command | Rejected for v1 | Zero pinned-wire edits, but the value of the surface is the comparison: a declared `busy` beside an observed `idle` is the wedged-agent signal, and a caller made to join two commands will skip it. The three pinned roster literals and the roster invariant wording change deliberately, in one change. |
-| Codex-only v1, other harnesses follow | Rejected | The TUI pins v1 when it ships; a fleet's Claude/pi/OpenCode seats reading `null` indefinitely re-creates the two-tier observability this exists to close. |
-| History (JSONL transitions) in v1 | Deferred | Measured burst coalescing — 4 transitions per turn, 0.1–0.4 ms apart (#268) — erases states shorter than the coalescing window, defeating the dwell-time analysis history is justified by. Deferred, not deleted: `transitions` + `sinceMs` make a later history additive. |
-
-## Evidence and Argument
-
-The signal already exists, typed and durable, for exactly one harness in the
-wrong place: `CodexObservedState` is written on every transition to
-`$XDG_STATE_HOME/st2/codex/<hash>/control-state.json`, and at current main it
-has no production reader — the pump rebuilds from `AwaitingStatus` on restart.
-So the Codex producer is a projection of shipped state, not a new observation
-path. The two rows #268's adversarial review corrected are binding here:
-`ActiveWithoutTurn` and `ConflictingTurn` project to `active`, because Codex
-positively reported activity and st2 merely cannot name a steerable turn; and
-`Held` never enters the published vocabulary, because it is defined as the
-complement of steerable — a delivery predicate, which decision 0001 already
-established must not govern an observability surface. pi is the strongest
-evidence for the evented path: the injected extension's `ctx.isIdle()` is a
-positive in-process signal (false exactly for `agent_start`..`agent_end`),
-which is the "stronger evented signal" root DQ2 asks for, on the one harness
-that already has a channel. On vocabulary provenance: the
-`idle|active|child|unknown × inputBuffer` words #268 reuses are from PR #123,
-which remains open — this decision *defines* those words for st2 rather than
-reusing something landed. The self-wake hazard #268 warns about is live today:
-the Codex delivery pump arms an unfiltered recursive watch on the whole agent
-directory while its own five-minute presence refresh writes into that tree, so
-scoping delivery-input watching is a prerequisite, not a precaution.
-
-## Consequences
-
-- The vocabulary (`idle`, `active`, `child`, `ended`, `unknown`; `blockedOn`;
-  `inputBuffer`) is defined by this decision and
-  [`05-harness-state`](../05-harness-state/requirements.md), not inherited
-  from PR #123. If #123 lands with different words, that PR reconciles to
-  these or supersedes this decision explicitly.
-- Homographs to manage: *observed harness state* is neither **presence**
-  (agent-authored), **session state** (task-record liveness), R08's declared
-  **activity status**, nor R09's **working state** (restored context). The
-  ontology pins all four apart.
-- The roster wire shape changes: the three full-string pinned assertions and
-  the stable-roster invariant wording are edited deliberately in the same
-  change that adds `observedState`, with the new proof named.
-- `blocked` is vacuous under `bypassPermissions`, which is what
-  `examples/native/agent-claude.kdl` ships today; a fleet running entirely on
-  it gains nothing from the axis until that changes (OHS-T02).
-- The OpenCode native delivery transport is designed against #242's contract
-  shape and does not wait for it; #242 reconciles at review.
-- The `.decisions/` series carries two documents numbered 0005 from separate
-  PRs. This decision takes 0006 and leaves the collision as recorded history;
-  numbers are not reused.
-- Root DQ2 and DQ3 are updated: pi gains an evented signal, the observed half
-  of DQ3 is specified here, and the declared half (activity status, plan,
-  plan step) plus supervisor-following behavior remain open.
-
-## Amendment: native-driver degradation is a sibling typed record
-
-Accepted by Johannes on 2026-08-27 for the OpenCode diagnostics scope.
-
-The observed-state record remains only the harness activity projection and
-delivery still reads none of it. Native-driver degradation is a sibling
-driver-core-owned current record,
-`<agent-dir>/driver-diagnostic` (`st2.driver-diagnostic.v1`), rather than
-free-form OpenCode strings added to `observedState` or interpreted separately
-by roster and Doctor. Its closed axes are stage, reason, source, support, and
-recovery outcome; producer version and observation time are evidence fields.
-The driver publishes at version/API/SSE/seed/delivery/read-back boundaries and
-clears on boundary recovery, without changing transport behavior.
-
-One persisted current snapshot was selected over a failure history or one
-record per stage. The in-process publisher may retain one failure per stage,
-but projects the earliest boundary so downstream symptoms cannot hide an
-admission failure; clearing that boundary reveals the next. History is still
-unjustified, and multiple files would make roster/Doctor choose precedence
-independently.
-
-Absence and unreadable/unknown records are visibly `absent` or
-`indeterminate`, never healthy. `agents --json` always projects that state;
-Doctor applies the same typed reader and stable repair policy where the
-declared native driver is expected to publish it. Telemetry repeats only the
-closed axes on
-metrics and `span.label`; raw versions and identities remain trace/log-only,
-and prompt/message/path content never enters the record or labels.

-# Child process output capture is bounded and tail-preserving
-
-Status: accepted
-
-Decision made by Johannes on 2026-08-25 (issue #339, independently reproduced
-measurements in the session record; option A of three, cap size 256 KiB).
-
-## Context
-
-The supervisor shell-out helpers (`src/run.rs`
-`output_with_input_timeout_observed`, `src/ding/mod.rs` `output_with_timeout`)
-redirect child stdout/stderr to tempfiles — sound, because files keep an
-escaped descendant from blocking cleanup and make bounded read-back
-deadlock-free — then unconditionally rewind both streams and `read_to_end`
-them into fresh heap buffers. Measured peak RSS scales 1:1 with child output
-(16 MiB child → +16.2 MiB RSS; 8 concurrent × 16 MiB → +103 MiB) despite doc
-comments claiming "bounded output capture". No spec or invariant defined a
-bound; the comment described aspiration, not behavior.
-
-Consumer inventory: only `pty list --json` (parsed JSON, naturally bounded by
-catalog size) and `pty peek` (terminal screen text, consumed for composer
-matching where the tail is what matters) need complete stdout. Every other
-call site uses stderr only trimmed inside error strings. The same audit found
-two sibling hazards: detached reaper threads accumulate without bound under
-timeout storms, and `src/eval_run.rs` holds whole step output plus full
-scrollback in memory before writing log files, with an undrained pipe pair in
-the bash judge that can deadlock.
-
-## Decision
-
-1. **Diagnostics capture is capped at 256 KiB per stream and tail-preserving.**
-   When a stream exceeds the cap, the last `CAPTURE_CAP_BYTES` bytes are kept;
-   the head is dropped. Truncation emits one diagnostic line naming the
-   command, stream, kept/total bytes, and cap.
-2. **Payload capture stays complete and explicit.** Callers that parse
-   structured data (`pty list --json`) use a distinctly named
-   full-stdout variant whose doc comment states that stdout is intentionally
-   uncapped and why. Bounded-tail remains the default so an uncapped read is
-   always a visible, deliberate choice at the call site.
-3. **One shared reaper thread** drains killed children over a channel,
-   replacing per-timeout detached threads.
-4. **Eval run steps stream to their log files** instead of buffering, and the
-   bash judge uses null stdio (only its exit status is consumed).
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Cap diagnostics; keep named payload capture complete | Selected | Bounds memory while preserving structured payload parsing. |
-| Spill oversized diagnostics to disk | Rejected | Adds spill-file lifecycle without a demonstrated consumer. |
-| Stream every shell-out to log files | Rejected | Changes every error path; revisit only if a consumer needs complete oversized diagnostics. |
-
-## Evidence and Argument
-
-The reproduced 16 MiB and eight-way concurrent probes showed peak RSS scaling
-with child output. The selected cap removes that scaling while retaining the
-tail that carries failure diagnostics.
-
-## Consequences
-
-- Peak supervisor RSS no longer scales with child output volume; worst case
-  is bounded by calls × 512 KiB regardless of child behavior.
-- Diagnostics for oversized children lose their head. Error messages built
-  from stderr keep their tail, which is where failure text lives.
-- The tempfile redirection is now load-bearing for more than cleanup: it is
-  what makes the bounded read-back deadlock-free. Any future move back to
-  pipes must preserve a bound on buffered bytes.

-# omp is a fifth native driver with its own channel and a hard version gate
-
-Status: accepted; admission policy revised 2026-10-02, explicit operator exception added 2026-10-03 for [#819](https://github.com/compoundingtech/fractal/issues/819)
-
-## Context
-
-st2 maintains four typed drivers (claude, codex, pi, opencode), each pairing a pure KDL
-expansion with a session wrapper that owns presence, publishes observed harness state, and
-delivers inbox messages natively. omp — an earendil-works/pi-family harness in daily use on
-this fleet — has none of this: seats are hand-authored tasks with no presence lease, no
-observed state, and no delivery path. The question was how deep support should go: a full
-native driver, an alias onto the pi driver's machinery, or a documented hand-authored
-pattern.
-
-## Options
-| Option | Result | Reason |
-| --- | --- | --- |
-| Full native driver (fifth expansion arm, own wrapper, own channel) | Selected | The 2026-08-25 capture shows the pi mechanism ports and omp's approval events add an axis pi lacks. Cost: ~pi-driver scale code and measured exact-build admission. |
-| Alias onto the pi driver | Rejected | Cheapest, but measured divergence makes it wrong: no `agent_settled` means the observed idle edge never fires or blips at `agent_end`, and version gates would pin the wrong harness. Rejected on evidence, not effort. |
-| Docs-only hand-authored pattern | Rejected | No presence lease, observed state, or native delivery; inconsistent with all four existing drivers — not "first-class". |
-| Blocked axis deferred out of v1 | Rejected | Smaller diff, but omp seats would read busy while actually waiting on a human — exactly what st2's wedged-agent signal exists to catch; both events verified firing (q2). |
-| Warn-only version handling | Rejected | omp releases near-daily; silent degradation reads as healthy while a refused launch is loud (q3). |
-
-## Evidence and Argument
-
-Measured against omp v18.0.3 on 2026-08-25; full record:
-[`06-omp-driver/.experiments/2026-08-25-omp-harness-integration.md`](../06-omp-driver/.experiments/2026-08-25-omp-harness-integration.md).
-
-- **The pi mechanism ports.** omp loads pi-style extensions; its extension argument carries
-  the same `sendUserMessage` / `sendMessage` / `on` calls; a live interactive run delivered
-  an idle message end-to-end and drove a complete model turn without touching a screen.
-- **But it is not pi.** `agent_settled` — the pi channel's entire idle edge — does not exist
-  (absent from the binary); idle must be derived by polling `ctx.isIdle()` after
-  `agent_end`. Conversely omp is *richer* than pi where it matters for st2: it exposes
-  `tool_approval_requested` / `tool_approval_resolved` with a `toolCallId`, giving the
-  blocked-on-human axis pi cannot express at all.
-
-An alias onto the pi driver would bake both divergences into the wrong place: observed state
-would hang waiting for an event that never fires or blip idle at the wrong boundary, and
-each future divergence would become a special case inside "pi". The measured differences
-are exactly why the channel forks rather than shares a file.
-
-## Decision
-
-1. **Full native driver** (`driver omp` block + `omp-session` wrapper + `omp-channel.ts`
-   extension + `omp-channel` process), per OMP-R01.
-2. **Own channel asset, forked from pi's**, not a shared parameterized file — the idle-edge
-   and approval logic differ per harness (OMP-R04).
-3. **Publish the blocked-on-human axis in v1** from the two approval events (OMP-R02) —
-   verified firing, not speculative.
-4. **Hard measured admission of the exact installed build** (OMP-R05). Before taking
-   ownership of a live seat, automatically measure the installed executable with the shipped
-   channel extension in a disposable RPC session. All five checks must pass: extension load,
-   lifecycle event names, a positive idle sample after terminal `agent_end`, a correlated
-   requested/resolved approval pair for a harmless isolated tool, and one native message consumed
-   in a completed model turn. The channel's `delivered` acknowledgement alone cannot prove
-   consumption. A failed or indeterminate check refuses omp launch; it names the boundary in
-   the durable driver diagnostic, the Agent API state and `st doctor`.
-   Persist results under exact release, executable/installation/interpreter identity, extension
-   contents, and probe/adapter implementation identity. A same-version build or extension
-   replacement requires fresh evidence. Concurrent launches share a bounded cache lock.
-   Scratch HOME, XDG, credential, workspace and PTY roots contain no managed declarations or
-   history; the model endpoint is loopback and the empty fixture approval is denied automatically.
-   OpenCode uses the same cache discipline and its own API/SSE/permission/completed-consumption
-   measurements; failure retains its explicit native-delivery-disabled policy.
-   A person may explicitly allow the exact installed executable/interpreter/installation and
-   shipped extension with `st admission override omp --binary <path> --reason <reason>` (or
-   `opencode`). This exception is a separate local audit record, never a forged pass. It bypasses
-   scratch probes, including version probing, for that build; failed measurements remain intact,
-   replacement builds/extensions need a new exception, and `st admission revoke` restores the
-   normal gate. The named failure diagnostic points to this remedy. This addition follows
-   the 2026-10-03 requirement to preserve a person's ability to start their seats when a probe
-   cannot run on their machine. It does not automatically downgrade the gate to a warning.
-5. **No DING screen adapter for omp** in v1 (OMP-T03), matching the other native-channel
-   drivers.
-
-Interview decisions q1–q4 (2026-08-25, Johannes): full native driver; blocked axis included;
-hard gate; VRS lives in [`06-omp-driver/`](../06-omp-driver/).
-
-## Consequences
-
-- A fifth expansion arm, wrapper module, channel process, hook asset, and ding launch
-  classification follow the existing per-harness pattern.
-- Every unseen exact producer/adapter build runs the isolated probe once. Successful new
-  versions require no st release or manual allowlist change. Refusals persist too; repairing
-  the named producer/adapter boundary and removing its cache record permits a new measurement.
-- Existing measured captures remain fixtures for the builds they measured. Admission proves
-  the narrow delivery contract, not model/provider matrices, context/token arithmetic, prices,
-  every interactive UI mode, or all steer/modal behavior. Those still require their own captures.
-- The original per-minor policy is superseded by automatic measurement, as agreed with
-  @schickling-assistant on #819. The default loud refusal and all five OMP-R05 checks are preserved;
-  a person's deliberate exception is distinguishable from measured admission.
-- Admission only gates a new provider launch, including restart and residency resume. Existing
-  running providers and driver adoption are unaffected; there is no rollback to an older binary.
-  Loopback fixture calls need no real model credentials or Internet, but a producer bootstrapping
-  a missing dependency in its empty scratch cache can still fail offline. The explicit exception
-  is available in that case; it cannot repair a missing runtime needed by the real producer.
-- The deny path, ask-axis discrimination, steer/modal interactions, and update-banner
-  suppression remain open (`DQ-OMP-1..5`) and bound v1's claims.

-# Resync events ride the built-in stream with occurrence-scoped carrier-state identity
-
-Status: accepted
-
-Amended by
-[decision 0009](./0009-resource-profiles-use-a-feature-gated-wasm-boundary.md):
-Q2 watch scope and Q3 classification now include declared Resource Profiles.
-
-Design decisions made by Johannes on 2026-08-25 (decision requests Q1–Q6,
-recorded in the ox-alpha.local decision tree), grounding
-[issue #341](https://github.com/compoundingtech/st2/issues/341).
-
-Decision 0009 adds profile-resolved local carriers to Q2 and makes the
-catalog-declared profile class authoritative for those carriers under Q3.
-Native `file://`/relative resolution and path-based class defaults remain as
-recorded here.
-
-## Context
-
-A live agent's context is assembled from declared resource carriers. When a
-carrier changes on disk after launch — configuration management replaced it,
-a supervisor republished it — the session keeps acting on the stale version
-until restart. Issue #341 proposes resync events: a supervisor notification
-into the owning agent's inbox, delivered like any other message.
-
-The delivery surface was already settled once: decision
-[0004](./0004-stream-events-are-a-distinct-record-kind.md) made stream events
-the second record kind, and `st2 event emit` with ring deduplication and
-producer-side supersession shipped. The open question was how resync events
-reach that machinery without a third mechanism, what they watch, how noisy
-they are allowed to be, and what their identity is.
-
-## Decision
-
-1. **Delivery (Q1):** a built-in per-agent stream named `resync` exists
-   without declaration; the supervisor emits through the unchanged ingress.
-   One carve-out in stream resolution accepts the reserved name for running
-   agents; declaring a user stream named `resync` is refused. No third
-   record kind; no declaration boilerplate; default-on for every running
-   agent.
-2. **Watch scope (Q2):** watchable carriers are local files only — absolute
-   `file://` URIs and catalog-relative paths resolved against the agent
-   directory. Other schemes are silently unwatched with observability in the
-   catalog projection. The agent's own declaration file is also a source.
-3. **Noise model (Q3):** fixed class defaults in code for v1 — immediate for
-   the declaration and goal carriers, silent for agent-authored stores,
-   coalesced for everything else. The per-binding `notify` attribute waits
-   for real volume data; this keeps the change out of the canonical Agent
-   Spec grammar and #305's Nix-regeneration coupling.
-4. **Event identity (Q5):** event-id = SHA-256 of the new carrier bytes,
-   key = binding label, every emit supersedes. Equal-content rewrites
-   deduplicate to no wake; A→B→A oscillations notify honestly each time the
-   content actually differs.
-5. **Build approach (Q6):** direct test-first implementation; the PR's
-   integration tests are the prototype evidence.
-
-## Amendment — 2026-08-26
-
-Johannes approved decision request Q12 to supersede the event-identity part of
-item 4. The event ID is SHA-256 of the canonical rendered transition body,
-which contains the binding label, resolved path, old digest, and new digest.
-The grouping key remains the binding label and every emit still supersedes.
-
-The original new-bytes identity could collide when two bindings or paths made
-the same byte transition: one `(stream, event-id)` then named different
-rendered content, so the unchanged ingress correctly rejected the second
-event. Hashing the body makes identity reuse imply byte-identical content.
-Equal-content rewrites remain quiet because digest comparison suppresses them
-before emission; old and new digests keep A→B→A legs distinct. The
-`transition_identity_covers_every_rendered_transition_dimension` matrix test
-proves binding, path, old-digest, new-digest, and stable-replay behavior.
-
-## Amendment — 2026-08-26 (Q13)
-
-Johannes approved decision request Q13 to distinguish repeated occurrences of
-the same rendered digest transition. The canonical transition body now also
-contains an occurrence token: the existing stream-owner supervisor incarnation
-`(catalog-lock device/inode, supervisor PID/start-time ticks)` plus a
-per-subscription sequence. The event ID remains SHA-256 of the complete
-canonical body.
-
-The sequence advances only when the subscription captures a new immutable
-transition. A failed emit retains and retries the exact body, token, and event
-ID; metadata refresh carries that reservation and the sequence with the
-subscription. Separate subscriptions advance independently. A supervisor
-restart changes the incarnation namespace and, under the v1 no-catch-up
-tradeoff, silently seeds fresh sequence state rather than adding a durable
-occurrence store.
-
-`repeated_identical_transitions_receive_distinct_occurrence_identities`,
-`failed_emit_retains_digest_and_schedules_the_same_transition_for_retry`,
-`subscribers_advance_occurrence_sequences_independently`, and
-`supervisor_restart_incarnation_changes_the_occurrence_namespace` prove the
-Q13 contract. The composition experiment records these tests as the direct
-evidence.
-
-## Amendment — 2026-08-27 (Q21)
-
-Johannes approved decision request Q21 to make carrier absence an observable
-state rather than an unreadable digest. A subscription now records
-`present(<digest>)` or `missing`. A proven present→missing transition emits a
-canonical tombstone (`old: <digest>`, `new: missing`), and missing→present
-emits a creation even if the recreated bytes have the same digest as before
-deletion. Repeated missing observations remain silent.
-
-Only `ENOENT` and a stable non-regular replacement establish `missing`.
-Permission and transient I/O failures retain the last proven state, emit a
-diagnostic, and retry. Failed delivery retains the exact carrier-state
-transition body, occurrence, and identity; a newer observation is considered
-only after that immutable reservation completes. Per-binding supersession and
-shared-carrier subscriber independence remain unchanged.
-
-`deletion_and_same_byte_recreation_are_distinct_carrier_transitions`,
-`initial_transient_read_failure_schedules_a_baseline_retry`,
-`transient_permission_error_retries_without_emitting_a_tombstone`,
-`fifo_carrier_is_rejected_without_blocking`,
-`failed_tombstone_emit_retains_present_state_and_immutable_retry_snapshot`,
-and the existing shared-subscriber occurrence tests prove the Q21 contract.
-
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Built-in reserved stream on the existing event transport | Selected | Reuses implemented dedup/supersede/DING semantics; zero declaration cost; one small resolution carve-out. |
-| Explicit declared `stream "resync" {}` per consumer | Rejected | Opt-in safety property silently missing when a spec forgets it; Nix-generated specs need regeneration (#305). |
-| Third record kind for resync | Rejected | 0004 settled two kinds on one transport precisely to avoid a third mechanism to publish, list, deliver, and test. |
-| mtime-serial event identity | Rejected | Wakes on no-op saves; mtime can move backwards on restore. Digests give strictly better noise behavior for carriers. |
-| Whole-set digest across all carriers | Rejected | Cross-binding churn on multi-writer catalogs; per-binding supersession already bounds unread heads. |
-
-## Evidence and Argument
-
-Source reads of this branch on 2026-08-25 established: the event ingress is
-implemented (`src/event.rs`: ring capacity 128, receipt validation,
-supersession); `resolve_stream` requires declaration plus running desired
-state, so the built-in name needs exactly one carve-out; the catalog watcher
-(`src/watch.rs`) deliberately prunes payload trees (#333/#335) so carrier
-watching must be explicit per-file, and its directory-identity tracking is
-the proven pattern that makes rename-replacement visible via parent-directory
-watches. Content-derived identity is sound here where it failed for world
-events because equal bytes genuinely mean equal state for an on-disk carrier
-(the unsoundness demonstrated in `04-stream/.experiments/` does not
-transfer). Q2–Q6 were decided by Johannes over these grounded options; Q1
-options were all grounded in the same reads except where marked otherwise.
-
-## Consequences
-
-- DING, inbox, archive, and stream-state code gain no new semantics; the
-  only core-code deltas are the reserved-name carve-out, the watcher, and
-  classification.
-- The `resync` stream name becomes reserved grammar; validation must refuse
-  shadowing from day one.
-- Window lengths and class membership ship provisional and are expected to
-  be amended after live observation (RESYNC-T02, DQ-R1).

-# Resource Profiles use a feature-gated wasm boundary
-
-Status: accepted
-
-Johannes selected the registry/SDK shape on 2026-08-26 (decision Q8), explicitly
-amending the prior dotfiles direction that rejected a semantic registry. After
-requesting real prototypes rather than a paper choice (Q9), he selected the
-wasm-only foundation (Q10) and its goal of absorbing userland complexity once
-inside a principled boundary. On 2026-08-27 he amended the decision (Q14):
-catalog-relative wasm modules are first-class transactional catalog inputs
-rather than external artifacts that happen to sit below the catalog root.
-
-## Context
-
-Root `R20` deliberately preserved Resource URIs while leaving their schemes
-open and downstream-owned. Resync could observe `file://` and relative paths,
-but a binding such as
-`dev.schickling.agent-goal://dev3/cos` remained unwatchable even when the local
-carrier was `<agent-dir>/resources/goal.md`. Hard-coding that private scheme in
-st2 would violate the portable envelope; leaving resolution to every consumer
-would reproduce security, lifecycle, and observability decisions in userland.
-
-Q8 chose an upstream registry/SDK boundary rather than a fixed catalog template
-or a dotfiles-owned contracts dependency. Q9 then required declarative,
-out-of-process exec, and wasm approaches to be built and measured against the
-same goal-resolution shape before choosing the runtime boundary.
-
-## Decision
-
-1. st2 owns an injectable, exact-scheme Resource Profile registry and typed
-   resolver SDK contract. The built-in registry is empty; scheme meaning stays
-   downstream-owned.
-2. A catalog-declared profile names one wasm module and one trusted
-   `immediate | coalesced | silent` notification class. Wasm is the only profile
-   mechanism: no declarative template tier and no host-exec tier.
-3. The module runs as closed core wasm: no WASI, no imports, finite fuel,
-   bounded linear memory, fresh instance state per resolution, and host-side
-   containment of returned paths under the agent directory. Compiled modules
-   are cached by path.
-4. Wasmtime is gated behind `wasm-resolver`. Default builds retain the baseline
-   dependency tree and binary surface; feature builds consciously absorb the
-   runtime cost.
-5. Resolver failure is contained to the binding. It becomes unwatchable, the
-   supervisor remains alive, and no alternate mechanism guesses a result.
-6. A non-absolute module declaration is normalized beneath the catalog root,
-   opened no-follow as a bounded regular file, and included by exact path and
-   bytes in the whole-catalog projection, root hash, snapshot, prepared bundle,
-   bootstrap, apply, and recovery. Duplicate normalized references deduplicate.
-   Literal absolute paths remain external inputs and are not copied. Apply
-   publishes new module bytes before the `catalog.kdl` that names them and
-   removes stale module bytes only afterward.
-
-
-## Options
-
-| Option | Measured runtime | Isolation and complexity | Result |
-| --- | --- | --- | --- |
-| Declarative path templates | warm **0.624 µs**; cold registry construction + resolve **2.647 µs** | Smallest runtime and declaration surface, but creates a second mechanism whose placeholders, validation, containment, documentation, and evolution st2 must own alongside programmable profiles. | Rejected as a separate tier. Static mappings use the same wasm boundary. |
-| Out-of-process exec plugins | compiled Rust cold p50 **760 µs** (p95 1,117; p99 1,603); bash p50 **2.901 ms** (p95 4.024; p99 4.941); TTL cache hits **0.1–0.4 µs** | Process isolation tests passed for exit, 60 s hang bounded by timeout, garbage, oversized output, and crash-mid-write. About **295 core LOC** once plus **12–16 LOC/profile**, but every plugin is ambient host code and repeats packaging/security review. | Rejected. Cold path is 38–145× wasm and execution is RCE by design. |
-| Feature-gated wasm plugins | warm p50 **0.29 µs**; cold p50 **20.1 µs**, p99 **33.8 µs**; compile module once **2.6 ms** | Closed sandbox; 12 isolation tests cover traps, fuel-bounded infinite loops, garbage returns, invalid memory, and oversized allocation. One runtime absorbs policy for every consumer. Costs **+71 lock packages**, **+16.35 MB / +188%** binary, and **+45.7 s** serial-equivalent compile work when enabled. | **Selected**, feature-gated. |
-
-A combined declarative-plus-wasm design was also viable on raw performance, but
-it preserved two resolver concepts forever to save roughly 18 µs on a cold call.
-The selected foundation values one auditable composition boundary over that
-imperceptible savings. Declarative-plus-exec was rejected because exec preserves
-neither one mechanism nor a sandbox.

-[`07-resource-profile/.experiments/2026-08-26-plugin-boundary-comparison.md`](../07-resource-profile/.experiments/2026-08-26-plugin-boundary-comparison.md).
-All three prototypes used the same logical operation: resolve
-`dev.schickling.agent-goal://<host>/<identity>` to
-`<agent-dir>/resources/goal.md` and supply a notification class.
-
-The wasm prototype established the properties that matter for a load-bearing
-plugin boundary:
-
-- a 1,469-byte Rust guest artifact implements the closed ABI;
-- the module receives no host imports or WASI capabilities;
-- 5,000,000 fuel units bound computation and 64 MiB bounds linear memory;
-- each resolution gets fresh store/instance state while compilation is cached;
-- the host validates memory, UTF-8/JSON, and lexical path containment;
-- twelve hostile-module tests leave the supervisor alive;
-- cold p99 is 33.8 µs, far below even a compiled exec plugin's p50.
-
-The cost is also material and was not hidden: a feature build grew the binary
-from 8,672,072 to 25,026,152 bytes, added 71 lockfile packages, and added 45.7 s
-of serial-equivalent compile work. That is why optional compilation is part of
-the decision rather than a later optimization. The repository dev shell also
-adds `lld`, required to link `wasm32-unknown-unknown` guests.
-
-The real-shape proof is recorded in
-[`07-resource-profile/.experiments/2026-08-26-dotfiles-real-shape-e2e.md`](../07-resource-profile/.experiments/2026-08-26-dotfiles-real-shape-e2e.md).
-The actual Nix-generated standing-seat declaration resolved through the wasm
-profile and observed a whole-file goal rename in about 600 ms, emitted exactly
-one deterministic resync event, and kept an equal-byte rewrite silent in two
-fresh runs. The selected boundary therefore composes with real catalog,
-watcher, and event behavior rather than only a microbenchmark.
-
-The Q14 amendment closes a deployment gap revealed in review: the original
-transaction projected `catalog.kdl` but omitted the relative module it named.
-That made a generated snapshot internally incomplete and caused a prepared
-catalog containing the module to fail as unprojected. Targeted transaction
-tests now bind module bytes into the root hash, deduplicate references, exclude
-absolute modules, reject traversal/symlink/FIFO/missing/oversized and
-unprojected inputs, and load a relative module from the applied live catalog.
-
-## Consequences
-
-- st2 assumes a permanent guest ABI compatibility obligation; versioning is
-  tracked as `DQ-P1` in the Resource Profile spec.
-- Operators who need profiles build with `wasm-resolver` and distribute guest
-  artifacts; operators who do not need them pay no wasmtime cost.
-- Even trivial path mappings require a wasm artifact. This is intentional: one
-  module boundary replaces recurring resolver-specific host logic.
-- Host-exec resolvers and declarative templates are not dormant alternate paths
-  or follow-up tiers. Adding either would require new evidence and a new
-  decision.
-- Scheme ownership remains federated. The registry maps exact strings supplied
-  by the catalog; it does not turn st2 into the authority for private URI
-  semantics.
-- Whole-catalog publication is deliberately superset-biased across crashes.
-  A failure can leave an unreferenced new or old module until recovery, but
-  ordered atomic leaf replacement prevents `catalog.kdl` from pointing at a
-  missing newly introduced module.
-- Resolver observability and same-path module-cache invalidation remain explicit
-  design questions; neither weakens the containment and feature-gating contract.
-
-## Amendment — 2026-09-01 (Q39)
-
-Johannes approved Q39 to make WASIp2 Component Model components the universal
-execution envelope for observable Resource providers. This amendment preserves
-the original decision's closed core-wasm resolver and replaces only the
-observable host-process mechanism described later by
-[decision 0014](./0014-resource-profiles-are-state-first-read-and-observe-capabilities.md).
-Decision 0014-resource-profiles-are-state-first-read-and-observe-capabilities's state-first authority, demand semantics, typed `Publication`,
-semantic filtering, and catch-up model remain in force.
-
-### Context
-
-The closed resolver has one pure job: map an opaque Resource URI to a contained
-carrier path. It needs neither provider I/O nor the Component Model. Observable
-providers have a different job: call a remote or local provider, normalize its
-domain state, and propose a canonical publication. A catalog-trusted native
-process can perform that job, but it carries ambient host authority and creates
-a second long-lived lifecycle and JSON protocol beside Wasmtime.
-
-Five disposable prototypes tested a narrower boundary with Wasmtime 48.0.1.
-Typed GitHub and PTY observations proved real domain I/O without exposing raw
-HTTP, caller-selected executable/arguments, environment, filesystem, or socket
-access. Fresh-Store cancellation tests ended with zero active tasks or
-capabilities. Verified compiled-code reuse kept a small provider's AOT disk-hit
-p50 at 0.482 ms and fresh Store plus instance observation p50 at 47.751 µs. An
-independent multiprocess oracle passed three 30-process runs covering
-one-winner compare-and-swap, stale generation, process-crash boundaries,
-acknowledgement loss, deterministic outbox identity, and restart catch-up.
-
-### Decision
-
-1. The core-wasm resolver ABI, its no-import sandbox, fresh resolution Store,
-   path containment, registry behavior, feature gate, and transactional module
-   ownership remain the only resolution mechanism.
-2. Every observable provider executes through one versioned WASIp2 Component
-   Model envelope. st2 does not maintain a parallel native or host-process
-   provider framework.
-3. A provider component may import only explicit provider-domain capabilities
-   linked by the host. The host owns credentials, allowlists, limits,
-   deadlines, cancellation, and redacted typed failures. No ambient WASI
-   command, environment, clock, random, process, raw HTTP, filesystem, or
-   socket authority is linked.
-4. Every descriptor call and observation receives a fresh Store and component
-   instance. Engine, Linker, compiled Component, and compatible host-produced
-   AOT bytes may be reused; Store and instance state may not be pooled or reset.
-5. The component returns `Unchanged`, a typed failure, or the existing
-   `Publication` payload. It never writes the carrier, state record, receipt, or
-   outbox. The host pairs a publication with
-   `ProposalFence { generation, revision, prior_digest }`, validates it, and
-   owns the only atomic commit.
-6. One durable transition makes the carrier, resulting digest and revision,
-   freshness and catch-up state, and deterministic `PublicationIntent` visible
-   together. A crash before publication leaves the old state. A crash after
-   publication but before acknowledgement leaves the intent retryable;
-   delivery remains separate and idempotent.
-7. WASIp3 production execution, Store pooling, generic exec/raw
-   HTTP/filesystem/socket authority, a parallel native provider framework, and
-   runtime WAC graphs are explicit non-goals. Each requires new evidence and a
-   further accepted decision rather than an alternate dormant path.
-
-### Evidence and argument
-
-The durable record is the
-[WASIp2 component and atomic publication experiment](../07-resource-profile/.experiments/2026-09-01-wasip2-component-and-atomic-publication-prototypes.md).
-The disposable harnesses prove the boundary; their local source, result, cache,
-and state paths are not production interfaces or scaffolding.
-
-The Component Model is selected for observable providers because its typed
-imports make authority reviewable at link time and its typed export preserves
-one observation result. Fresh Stores remove the need for an incomplete reset
-protocol across guest memory, resources, host state, traps, and cancellation.
-Host-only commit prevents a network- or command-capable guest from bypassing
-validation or racing publication against settlement. The deterministic durable
-outbox makes publication and delivery intent one crash-consistent fact without
-claiming exactly-once effects across an external sink.
-
-### Consequences
-
-- A profile may carry two wasm artifacts with deliberately disjoint jobs: a
-  closed core module for resolution and, only when observable, a WASIp2
-  component for provider observation.
-- Provider support requires a reviewed typed host capability; adding a generic
-  authority under a domain-flavored name is non-conforming.
-- Domain acquisition state such as ETags, cursors, rate limits, and webhook
-  repair cannot rely on guest Store lifetime. It belongs in bounded host-owned
-  capability state or explicit durable provider state.
-- Compiled-code caching is an optimization, not an authority transfer. Any AOT
-  deserialize path must authenticate exact host-produced bytes and the complete
-  engine-compatibility key before crossing Wasmtime's unsafe boundary.
-- Decision 0014-resource-profiles-are-state-first-read-and-observe-capabilities's host-process topology and newline-delimited JSON mechanism
-  are superseded. Its publication, demand, delivery, and state-first semantics
-  apply to direct component invocations.

-# The linked-record plane is retired and `resource` names one concept
-
-Status: accepted
-
-Design decision made by Johannes on 2026-08-27 (interview over the
-07-resource measurements and
-[dotfiles#2071](https://github.com/schickling/dotfiles/pull/2071)). Merge and
-acceptance approval required: upstream maintainers.
-
-## Context
-
-Two durable edges were both called *resource*: Agent Spec Resource bindings, and
-the link records written by `st2 resource add`. An agent reading one while
-reasoning about the other measured the wrong store — a declaration with five
-bindings and no link records reported `# 0 resources`, and a declaration with
-two bindings and fourteen link records reported fourteen rows containing neither
-binding. Both surfaces answered correctly; neither said which question it had
-answered.
-
-The measurements (07-resource `.experiments/2026-08-27-resource-read-surfaces.md`,
-one live catalog of 655 declarations) established that the planes are disjoint by
-construction rather than by coincidence: 889 distinct binding URIs and 233
-distinct link URLs share **zero** members, exactly or normalized. Bindings carry
-what an agent is for; link records carried what it produced.
-
-They also established that the link plane is legacy. It was adopted by 82 of 655
-declarations, its creation rate decayed from a peak of 45/day on 2026-08-08 to
-none after 2026-08-26, **the only reader of a link record in the source tree is
-its own `ls`/`read` verb**, and `axe work update --artifact <path> --pty <name>`
-now covers the job — matching the observed `relation` values (`output` 185,
-`evidence`, `produces`) and the 8 `pty://` URLs.
-
-## Decision
-
-The linked-record plane is **retired**. `st2 resource add|ls|read|remove` and
-`resources/links/` are removed, and *resource* names exactly one concept: a
-declared Resource binding. The freed verb becomes the binding surface, which the
-declared plane never had — bindings were previously visible only through
-`st2 agents --json`.
-
-The 241 existing records are left in place as orphaned files rather than
-migrated. Most belong to retired declarations whose worktrees are gone, and
-`axe work` writes to a gitignored per-worktree path that no longer exists for
-them.
-
-Producing agents record artifacts through `axe work update --artifact/--pty`.
-
-## Consequences
-
-- `resource` is unambiguous across the CLI, the declaration, and the corpus.
-  The read that produced the friction cannot recur, because there is no second
-  plane to read.
-- `<agent-dir>/resources/` is untouched and remains canonical for an agent's
-  resource files. Only `links/` goes. The directory is the realization surface
-  for bindings, not a second sense of the word.
-- `templates/bus.st2.md` loses the advertisement that produced the adoption.
-- Surviving `resources/links/` files become unreferenced. The ontology keeps a
-  retired entry so a reader who meets one can identify it.
-- Nothing downstream breaks: no consumer other than the retired verb read them.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Retire the plane; `st2 resource` becomes the binding surface | Selected | Nothing but its own verb ever read a linked record, adoption was 12.5% and decaying, and `axe work update --artifact/--pty` covers the job. Retiring makes *resource* unambiguous by removing the second plane rather than by wording around it. |
-| Freeze read-only: keep `ls`/`read`, drop `add` | Rejected | Keeps records reachable, but *resource* keeps naming two things for as long as any record survives, so the misread stays possible. |
-| Migrate the 241 records into `axe work`, then retire | Rejected | Highest fidelity, but `axe work` writes to `<repo-root>/tmp/worklog/`, gitignored and per-worktree; most of the 82 declarations are retired and have no reachable worktree to write into. |
-| Keep and invest: add `--json`, a requirement, a consumer | Rejected | Asks the fleet to adopt a second evidence ledger beside the one it already uses. In the plane's whole lifetime nothing consumed it. |
-| Unify both planes behind one typed reference ([#122](https://github.com/compoundingtech/st2/issues/122)) | Rejected | With zero measured overlap a shared descriptor deduplicates nothing and joins nothing, and #122's proposed `{_tag, uri}` assumes a field removed in #307. |
-
-## Evidence and Argument
-
-The measurement is
-[`07-resource/.experiments/2026-08-27-resource-read-surfaces.md`](../07-resource/.experiments/2026-08-27-resource-read-surfaces.md),
-taken against one live catalog of 655 declarations. Three findings decide it.
-
-**The planes are disjoint by construction.** 889 distinct binding URIs and 233
-distinct linked-record URLs share zero members, under exact match and after
-normalization on all five schemes both planes used. 81 of the 82
-linked-record-carrying declarations also carried bindings, so they coexisted
-constantly and still never named one thing. The cause is semantic: 728 bindings
-were self-state carriers and 378 were work inputs, while 196 of 241 linked
-records were `output`, `produces`, `evidence`, or `verified`. That is what kills
-#122 — a shared type has nothing to deduplicate.
-
-**The plane was write-only.** A source search for `links_dir` finds exactly two
-readers, both inside the `st2 resource ls|read` implementation. No projection,
-roster, or doctor consumed a linked record in the plane's lifetime.
-
-**It was already being abandoned.** Creation peaked at 45 records on 2026-08-08,
-fell to 5 on 2026-08-26, and stopped; 14 of the 25 most recent records come from
-one declaration on one day. Meanwhile `axe work update` grew `--artifact` and
-`--pty`, which match the observed `relation` values and the 8 `pty://` URLs
-exactly.
-
-The counter-argument — that low adoption is a surfacing problem, not obsolescence
-— is answered by the second finding: a plane nothing reads cannot be surfaced
-into usefulness by adding `--json` to it.

-# Working state is a declared carrier under `working-state://`
-
-Status: accepted
-
-Design decision made by Johannes on 2026-08-27 (interview; supersedes the open
-part of [#261](https://github.com/compoundingtech/st2/issues/261), which asked
-st2 to pick the name). Merge and acceptance approval required: upstream
-maintainers.
-
-## Context
-
-An agent's self-state carriers are declared as Resource bindings and realized
-under `<agent-dir>/resources/`: `dev.schickling.agent-goal://` realizes as
-`resources/goal.md`, `decision-tree://` as `resources/context/decisions/`, and
-so on for notes, private notes, and the friction log.
-
-Working state — R09's restored durable context, written through `st2 context` —
-is the exception. Measured on one live catalog of 655 declarations, 605 have a
-`resources/context/now.md` and **none declares it**; no binding URI anywhere
-mentions it. Consumers reach it by joining a literal path onto the declaration's
-own directory, which one downstream author annotated in-line as "a CONVENTION,
-not a declaration".
-
-## Decision
-
-Working state becomes the sixth self-state carrier, declared like its siblings:
-
-```kdl
-resource "working-state" \
-  uri="working-state://<host>/<identity>" \
-  reason="Working state for lossless restart."
-```
-
-realized at `<agent-dir>/resources/context/now.md`, resolver owned by st2
-(`st2 context`). The binding grants no authority, as for every binding.
-
-The scheme is **`working-state`**, un-prefixed. It takes the ontology's already
-canonical term for R09's restored durable context — a term the ontology also
-already guards against being read as a liveness or activity signal — and the
-scheme inherits that guard.
-
-## Consequences
-
-- The carrier is addressable by URI like its five siblings, so a consumer
-  resolves a declaration instead of walking a path.
-- The ontology gains a `working state` entry naming the term, the verb, the
-  realization path, and the scheme.
-- Declaring it across the fleet is a bulk binding write, which is why it
-  sequences after the mediated write surface (decision 0013).
-- This needed no requirements change. It was first drafted as a new requirement
-  (**R35 st2-owned Resource profiles**) because R20 then read "st2 does not
-  register schemes", which a scheme st2 resolves would have contradicted.
-  [#351](https://github.com/compoundingtech/st2/pull/351) landed first and
-  rewrote R20: a scheme is now the exact lookup key for an optional,
-  catalog-declared Resource Profile. That removes the barrier R35 existed to lift,
-  and R35's own text — an exemption from a clause R20 no longer contains — became
-  incoherent, so it was dropped rather than rebased.
-
-  `working-state` is therefore an ordinary scheme under the merged R20. st2's
-  `st2 context` writes the carrier at `resources/context/now.md`; whether any
-  catalog registers a Resource Profile that resolves the scheme is a downstream
-  choice this decision does not make, and R20's "st2 ships no built-in profiles"
-  stands untouched.
-
-## Amendment 1 — 2026-08-28
-
-The requirements delta this decision originally carried is withdrawn. Nothing
-about the carrier, its scheme name, or its realization changes; only the
-justification does, because #351 made the exemption unnecessary. See the bullet
-above.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| `working-state://` | Selected | Takes the ontology's already canonical term for R09's restored durable context — a term the ontology also already guards against being read as liveness or activity — so the scheme inherits the guard. No known downstream clash. `decision-tree://` sets the un-prefixed precedent. |
-| `agent-context://` | Rejected | Matches the `st2 context` verb, the `resources/context/` directory, and the `agent-notes://` prefix pattern, but [#261](https://github.com/compoundingtech/st2/issues/261) states the requesting consumer already uses "Agent Context" for message-envelope relations. Hands them a collision for internal symmetry. |
-| `agent-state://` | Rejected before posing | *State* is the most overloaded word in this ontology — session state, observed harness state, desired state, presence — which already carries explicit collision rules. A scheme by that name recreates the ambiguity this work removes. |
-| `agent-working-state://` | Rejected | No clash and full prefix symmetry, but `agent-` carries no information: every per-agent carrier is per-agent and the URI authority already names the agent. |
-| Leave working state undeclared | Rejected | `st2 context read <identity>` already resolves it, but the five sibling carriers are declared and the asymmetry is what forces downstream path-joining and filesystem crawls. |
-
-## Evidence and Argument
-
-Measured on one live catalog of 655 declarations
-([experiment](../07-resource/.experiments/2026-08-27-resource-read-surfaces.md)):
-605 declarations have a `resources/context/now.md`, **none** declares it, and no
-binding URI anywhere mentions it. Every other near-universal per-agent carrier is
-declared — `notes` on 618 declarations, and `goal`, `private-notes`,
-`friction-log`, `decisions` on 27 each — and each realizes into the same
-`resources/` directory that working state realizes into.
-
-So the asymmetry is not a design boundary, it is an omission: the one carrier st2
-itself writes, through `st2 context`, is the one carrier nothing declares.
-
-#261 documents what the omission costs a consumer — a TUI joining a literal path
-onto the declaration's directory, annotated in-line by its own author as "a
-CONVENTION, not a declaration", plus an hourly timer crawling
-`find <agent>/resources` behind a hand-maintained exclusion list to report which
-live declarations lack a `now.md`. Both are downstream workarounds for a fact
-that no declaration states.
-
-The naming argument turns on which layer owns the word. The verb and the
-directory both say *context*; the ontology says *working state*, and says it in a
-rule that already exists to stop the term being confused with liveness. A scheme
-is read far from its verb, so it should carry the term that travels with its own
-guard.

-# `st2 resource` is a mediated binding write surface
-
-Status: accepted
-
-Design decision made by Johannes on 2026-08-27 (interview; answers
-[#231](https://github.com/compoundingtech/st2/issues/231)). Merge and acceptance
-approval required: upstream maintainers.
-
-## Context
-
-Changing one declared binding requires the caller to render a complete candidate
-`agent.kdl`, validate it, compute its digest, publish under compare-and-swap, and
-read it back. That ceremony is safe and disproportionate.
-
-It also has a measurable consequence. Of 241 link records on one live catalog, 45
-were not products at all but dependency and reference edges — `current-work`
-(which duplicates the `work` binding), `depends-on-slice-*`, `supervises`,
-`blocked-design`. Agents wrote them into the linked-record plane because that was
-the plane they were permitted to write cheaply. **The drift between the two
-planes was caused by write-cost asymmetry, not by two different relations.**
-
-Retiring the linked-record plane (decision 0011) removes the escape hatch. It
-does not remove the pressure that produced it.
-
-## Decision
-
-`st2 resource` gains mediated write verbs alongside `ls` and `read`:
-
-```text
-st2 resource add <name> --uri <uri> --reason <text>
-st2 resource remove <name>
-st2 resource rename <old> <new>
-```
-
-Each performs read-modify-CAS-publish internally. The caller never renders KDL.
-Full-catalog validation, exact-target selection, compare-and-swap, and
-fail-closed concurrent-change behavior are preserved, and a binding-only change
-does not stop, replace, or relaunch healthy work (R21).
-
-This is the fourth instance of an existing pattern, not new machinery:
-`src/agent_author.rs` already mediates `add_stream`/`remove_stream`
-(`st2 agent stream`), `set_desired_state` (`st2 agent desired-state`), and
-`set_presentation` (`st2 rename` / `st2 describe`).
-
-## Consequences
-
-- The reason agents reached for the cheap plane is removed, not just the plane.
-- Declaring the working-state carrier (decision 0012) across a fleet becomes one
-  command per declaration instead of a rendered-and-published candidate each.
-- URI possession still grants nothing. A mediated write changes a declaration;
-  it does not touch the thing the URI names, and confers no access to it
-  ([#61](https://github.com/compoundingtech/st2/issues/61)).
-- Authoring authority is unchanged: whoever may publish the declaration may
-  mutate its bindings, and no one else.
-
-## Limits
-
-This does not address a declaration generated read-only by configuration
-management, where the next activation overwrites a runtime edit
-([#305](https://github.com/compoundingtech/st2/issues/305)). On the catalog
-measured, declarations are writable regular files carrying
-`meta { managed-by "agent-spec-authoring" }` with no `/nix/store` symlinks, so
-the mediated write applies there. The generated-declaration case stays open in
-[DQ-R4](../07-resource/open-questions.md).
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Read plus mediated `add`/`remove`/`rename` | Selected | Removes the cause of the drift, not just its symptom. The machinery is the fourth instance of an existing pattern in `src/agent_author.rs`, so the marginal risk is small. |
-| Read-only `ls`/`read` | Rejected | Smallest change and a literal reading of #61's read-oriented boundary, but it leaves the write-cost asymmetry intact while decision 0011 removes the escape hatch — pressure with nowhere to go. |
-| Ship read-only now, add writes as a follow-up | Rejected | Sequences a breaking rename away from a new write path, which is genuinely safer, but leaves the same interval in which agents have an expensive plane and no cheap one. |
-
-## Evidence and Argument
-
-The link-record census supplies the causal evidence. Of 241 records, 196 are
-products — the plane's stated purpose. The remaining 45 are not: `supervises`
-(11), `reference` (7), `current-work`, `depends-on-slice-1`,
-`depends-on-slice-2`, `depends-on-slice-5`, `depends-on-slices-1-4`,
-`blocked-design`. `current-work` duplicates the `work` binding outright, and the
-`depends-on-slice-*` records are dependency edges filed in a products store.
-
-Agents did not confuse the two planes. They wrote dependency edges into the
-products plane because a binding required publisher authority and
-whole-declaration republication under compare-and-swap, while a linked record
-required one file write. The observed misfiling is what write-cost asymmetry
-looks like from the inside.
-
-That the machinery already exists is the second half of the argument.
-[`src/agent_author.rs`](../../../src/agent_author.rs) implements exactly this
-read-modify-CAS-publish shape three times — `add_stream`/`remove_stream` behind
-`st2 agent stream`, `set_desired_state` behind `st2 agent desired-state`, and
-`set_presentation` behind `st2 rename` and `st2 describe`. Bindings are the
-fourth field of the same declaration, mutated by the same protocol; this is a new
-caller of proven machinery rather than a new mechanism.
-
-[#231](https://github.com/compoundingtech/st2/issues/231) asked for precisely
-this and listed the properties it must keep — full-catalog validation, exact
-target selection, CAS, fail-closed on concurrent change, non-disruption of
-healthy work, and machine-readable publication evidence. All are properties the
-existing three callers already have.

-Design decision made by Johannes on 2026-08-29 (an interview over four research
-reports and one throwaway spike, all recorded in
-[`08-harness-context/.experiments/2026-08-29-context-signals-and-write-placement.md`](../08-harness-context/.experiments/2026-08-29-context-signals-and-write-placement.md)).
-Interview handles q1–q11. The write policy (q6) was deliberately deferred at
-interview to a benchmark and settled on it —
-[`08-harness-context/.experiments/2026-08-29-write-policy-benchmark.md`](../08-harness-context/.experiments/2026-08-29-write-policy-benchmark.md).
-That benchmark also found that neither driver record would replicate at all;
-q11 settles how (the transport's include list names them, rather than the
-records moving). Merge and acceptance approval required: upstream maintainers.
-
-## Context
-
-st2 exposes what an agent declares (presence), and — since
-[decision 0006](./0006-observed-harness-state-is-a-driver-written-catalog-record.md) —
-what its harness is observed *doing*. It exposes nothing about how full that
-harness's context window is. The motivating failure mode is context saturation:
-a runtime fills its window and compacts, or wedges, with nobody watching.
-
-Nothing in the fleet watches it today. The dotfiles status-line renderer already
-parses Claude's `used_percentage` and prints it without persisting anything; the
-dotfiles hook chain maps `PreCompact` to a transient PTY event with no counter;
-tokenlens — the fleet's registered token and cost producer — has a
-transcript-derived `compaction_count` and no context-window column at all, and
-lists context replay as future work. No st2 supervisor, reconcile, or flapping
-path reads any harness record.
-
-The 2026-08-29 measurements established that all five maintained harnesses
-publish occupancy on a channel st2's drivers already sit on, that no two compute
-it the same way, and that two of them positively report "I do not know" where a
-naive producer would report zero. What remained was where to put the numbers,
-how often to write them, what vocabulary to publish, and what anyone is allowed
-to do with them.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Sibling record `<agent-dir>/harness-context` with its own lock, write policy, and 60-min horizon (q4) | Selected | The numeric axis wants a movement guard; the state record's guard is an equality test over a categorical tuple and cannot express one without redefining `sinceMs` and `transitions`. The sibling also keeps the numbers readable when the state derives `unknown` — the wedge case — and the delivery watcher's allowlist makes it inert with no production change. Accepted cost: ~65% more production code than folding it in, and one more file per agent. |
-| `context` sub-object inside `harness-state`, coalesced onto state transitions and the 5-min refresh | Rejected | Zero extra writes and ~40% less code, but measured to report the number the turn *started with* for up to five minutes; needs its own `context.observedAtMs` because `heartbeat()` re-stamps without re-reading; needs a merge rule because context-blind observations would erase the numbers; and drops them on all seven `unknown` derivations. Defensible for "roughly how full is this agent", wrong for "warn me before it compacts". |
-| Inside `harness-state`, every reading a transition (A-strict) | Rejected | Measured `2 + 2K` writes per turn (32 for a 15-tool-call turn), and it silently redefines two shipped fields: `sinceMs` becomes a token-delta stamp and `transitions` a turn counter. |
-| Inside `harness-state`, every reading a "quiet" write that opens no transition | Rejected | Same write count as A-strict by construction, and it adds a third write class ("changed but not a transition") to the module whose invariant is that a landed write *is* a transition or a refresh. Named in the spike, not implemented. |
-| Harness-native `usedTokens` / `windowTokens` / `usedPercent` (q2) | Selected | `usedPercent` is the number the harness itself displays, so it agrees with what the operator sees; raw tokens ride along for anyone doing their own arithmetic. `harness` is the discriminator for which rule produced it. |
-| One normalized st2 formula across harnesses | Rejected | One physical meaning, but it disagrees with every harness's own UI — by the 12,000-token baseline on Codex (36% vs the displayed 33%), and by output plus cache between omp and pi. That disagreement is the first thing a human files as a bug. |
-| Percent only, no raw tokens | Rejected | Smallest record, but it cannot show that a window *shrank* (a model switch), cannot be recomputed, and hides the join OpenCode's producer has to make anyway. |
-| Compaction as a counter plus last time and trigger in the record (q3) | Selected | One write per compaction (rare); "how many times has this runtime compacted" is answerable from the roster. Per-compaction detail is not recorded. |
-| Compaction as an event on the agent's stream, record carries nothing | Deferred | Full history with per-event detail, but the roster cannot show a count without folding the stream, and the hook-subprocess producers have no stream-append plumbing. Kept as the roadmap direction, together with the deferred state history (`OHS-T03`, `DQ-C6`). |
-| Provenance-only fencing: `incarnation` carried, the relaunch claim removes the record (q7) | Selected | A stale token count says only "this number is older than you think", which the origin timestamp already says. One extra file operation on the claim path buys "no context yet" after a relaunch instead of the previous incarnation's fill. |
-| Reuse the state record's incarnation + seq + claim + floor sidecar | Rejected | Roughly doubles the sibling's production code to duplicate a protocol whose only justification is preventing a dangerous *state* lie. |
-| Advisory only, mirroring `OHS-A02` (q1) | Selected | A wrong-but-fresh number can mislead an operator; it cannot misdeliver or end a runtime. Supervisor actionability would first have to settle `DQ-H5`, unmet and one of the reasons decision 0006 ships Draft. |
-| Supervisor may branch on the number now | Rejected | Requires bounded-staleness semantics for a remote reader (`DQ-H5`) and an action vocabulary, in this effort. An action taken on a stale reading is not undone by a spec edit. |
-| Also carry `model`, `costUsd`, `rateLimits`, `sessionTotalTokens` (q9) | Selected | Each arrives free on a channel already being read. `model` is what explains a mid-session window change; cost was explicitly in scope; the two contested fields are carried with their limits documented rather than dropped. |
-| Fixed 1% quantization + compaction edge + 300 s heartbeat as the write policy (q6, benchmarked) | Selected | The only measured policy with zero missed high-occupancy warnings at every threshold from 80% to 97%; error bounded at one bucket unconditionally; writes per window fill capped at 100 by construction, so producer chattiness cannot inflate cost and one constant serves all five harnesses. |
-| The spike's movement guard (≥5% move bypassing a 60 s floor) | Rejected | Dominated on both axes, and structurally rather than by mistuning: its time floor, not its movement clause, sets its rate (1%, 5%, and 10% all yield 59 writes/active-hour at T=60 s), so cost tracks harness event cadence and would need per-harness constants. Misses 23% of warnings at 90% occupancy, 57% at 94%. |
-| A coarser 5% bucket (2.6× cheaper) | Rejected | Perfect at multiples of five and worse than the movement guard between them — 51–79% of warnings missed at 91–94% — which couples the write policy to wherever a future reader sets its alarm. Cost is not binding anywhere in the candidate set, so buying that coupling away is the right trade. Named as the fallback if wire cost ever binds, at 2%. |
-| Write every distinct reading | Rejected | Most real-time and still only 1/110 of the rate `DQ-H2` recorded as a failure — cost genuinely does not forbid it — but it is 3× the recommended policy for no measured accuracy gain, and it reinstates exactly the restatement pattern `DQ-H2` caught. |
-| Write only at turn boundaries | Rejected | 48.8% p95 error, 92% of warnings missed. The wedge scenario is a single long turn, which this policy is silent through. |
-| Name the driver records in the transport's include list, keeping them at the agent-directory root (q11) | Selected | The records matched none of the transport's globs and would silently never replicate, defeating the reason decision 0006 chose a catalog record at all. Naming them fixes the **already-shipped** `harness-state` too, with no migration of a live record, and keeps driver records out of a directory whose meaning is the Resource-binding realization surface. Cost: a cross-repository change, and an include list st2 does not own. |
-| Move the record under `resources/` to match the existing globs | Rejected | Fixes only the new record and leaves `harness-state` unreplicated; puts driver runtime state on the Resource-binding realization surface; and contorts a record's location to fit a glob written for other purposes. |
-| Chain the status-line tee to the operator's renderer (`DQ-C3`, captured) | Selected | Measured precedence is `.claude/settings.local.json` > `.claude/settings.json` > `~/.claude/settings.json`, and the winner *replaces* rather than merges — one slot, one command. Since the st2 materializer writes the winning file, not chaining would silently remove the operator's status line on every managed agent. |
-| Doctor warns at a named st2 threshold, advisory-only (q10) | Selected | The record's whole purpose is that a human notices a filling window; a roster field nobody reads is not that. Advisory-only keeps it inside HC-A02 — Doctor already treats the categorical axis this way, and an exit-code failure would make an unfenced, advisory number gate a health check. |
-| Doctor threshold set to each harness's own compaction point | Rejected | It would make the warning a prediction st2 cannot make: the point depends on harness, model, and operator settings (Codex's baseline plus a separate auto-compact buffer, pi's `reserveTokens`, omp's idle threshold, Claude's overridable window), and it would silently change meaning on a harness bump. |
-| No Doctor output; roster only (the earlier `DQ-C4` position) | Rejected | Leaves the saturation signal to whoever thinks to read the roster, which is the invisibility this record exists to end. |
-| New subsystem `08-harness-context/` with its own triple (q8) | Selected | A clean ontology boundary between the categorical and numeric axes, and a fresh requirements file rather than an edit to a protected one. `08` is the next unused prefix (`06` and `07` already carry duplicate prefixes). |
-| Extend `05-harness-state` with `OHS-R16+` and amend decision 0006 | Rejected | One home for "what a driver observes about its harness", with the diagnostic record as precedent — but it would keep a subsystem named "harness state" carrying three records with three different guards, and needs an edit to a protected requirements file. |
-
-## Evidence and Argument
-
-**The guard is the discriminator, not the placement.** The spike built both
-placements end to end and counted byte-distinct landed writes per simulated
-Claude turn: 1 / 1 / 3 for the sibling at 0 / 5 / 15 tool calls, against 2 / 2 /
-2 for a coalesced sub-object and 2 / 12 / 32 for a strict one, on a baseline of
-2. What the measurement says is right — write when the number moved
-meaningfully, at most once a minute otherwise, always on a compaction — needs a
-prior-value comparison, an elapsed-since-reading check, and a move-fraction test
-folded into `observe_inner`, the most invariant-dense function in that module,
-on top of the byte-distinctness, ownership-sequence, and refresh-cadence logic
-already there. The sibling expresses the same policy in a twenty-line guard with
-nothing else in scope.
-
-**The wedge case is exactly where the sub-object goes blind.** The state
-record's reader routes stale, future-skew, unsupported-schema, literal-unknown,
-claimed, unfenced, and session-dead through one `unknown` constructor that
-builds a fresh value. A runtime at 190k of a 200k window whose state has gone
-indeterminate would report no numbers at all — the one moment they matter. The
-sibling has no `unknown` to derive: a stale reading is returned with its age.
-
-**No single formula exists.** Claude computes
-`(input + cache_creation + cache_read) / context_window_size` as a clamped
-integer; Codex subtracts a hardcoded 12,000-token baseline from both numerator
-and denominator of `last.totalTokens / modelContextWindow`; pi returns last
-assistant `totalTokens` and omp — on a byte-identical API — returns last
-assistant `input` alone; OpenCode publishes no percent at all and needs a
-two-source join. Both harness constants are properties of a build, not of a
-documented contract, which is why they inherit the omp version-gate discipline
-and a per-harness pinned fixture (HC-R13).
-
-**Two harnesses model honest ignorance already.** pi returns
-`{tokens: null, percent: null}` after a compaction and holds it across a
-restart; Claude's status line reports null percentages until the first API
-response. Both map directly onto the discipline `OHS-R02` sets for the
-categorical axis, and both are why HC-R03 forbids substituting a value for a
-harness-declared null.
-
-**The Claude window has exactly one source.** Hook payloads carry no token
-fields, and the transcript carries per-message `usage` but no window size — so a
-transcript-only producer would have to guess the denominator from a model table
-that cannot distinguish a 200k tier from a 1M tier for one model id. The
-`statusLine` settings slot carries `context_window_size`, `used_percentage`,
-`cost.total_cost_usd`, `model.id`, and `rate_limits` in one payload, and there
-is exactly one such slot — hence the tee, and hence the cross-repo contract with
-dotfiles that owns it today (`DQ-C2`, `DQ-C3`).
-
-**The sibling costs nothing at the watcher.** The delivery watcher is an
-allowlist over the inbox subtree and the presence record, so a new sibling file
-wakes no pump with no production change; only the invariant row's prose, which
-enumerates siblings by name, moves.
-
-## Decision
-
-1. **A sibling record** `<agent-dir>/harness-context`, schema
-   `st2.harness-context.v1`, its own lock, its own staleness and future-skew
-   constants, sharing only an extracted lock-and-atomic-write helper with the
-   state record (q4; replication per item 11).
-2. **Harness-native vocabulary**: `usedTokens`, `windowTokens`, and a
-   `usedPercent` that is the number the harness itself displays, discriminated
-   by `harness`; a producer that cannot obtain a window withholds the percent
-   rather than guessing (q2).
-3. **Compaction as a counter**: `compactions`, `lastCompactionMs`, and
-   `lastCompactionTrigger` over the closed union
-   `manual | auto | threshold | overflow | idle | unknown`, with the count's
-   scope (incarnation or harness-durable) stated per harness. History is
-   deferred to a follow-up that answers it once for this axis and the
-   categorical one together (q3).
-4. **Stale readings are returned**, marked stale and carrying their age, and the
-   numbers survive every `observedState: unknown` derivation (q4).
-5. **A fourth roster axis** `context` in `st2 agents --json`, always emitted and
-   `null` when absent, following the roster's existing null convention (q4).
-6. **st2 owns the Claude `statusLine` slot** for driver-declared agents: a tee
-   that records the payload and then execs the operator's downstream renderer;
-   compaction edges keep coming from hooks, with `PreCompact` routed through the
-   observe path in addition to the existing pre-compact stub (q5).
-7. **Provenance-only fencing**: `incarnation` is carried and never consulted as
-   a fence; the relaunch claim on the state record also removes the context
-   record (q7).
-8. **Advisory only** (q1), mirroring `OHS-A02`.
-9. **Adjacent facts carried**: `model`, `costUsd`, `rateLimits`, and
-   `sessionTotalTokens`, each documented as harness-reported (q9).
-10. **Fixed quantization is the write policy** (q6, settled by benchmark): write
-    on a change of `floor(used / (HARNESS_CONTEXT_BUCKET_PERCENT% of window))`,
-    on any compaction edge, or when the record is older than
-    `HARNESS_CONTEXT_HEARTBEAT` — 1% and 300 s, one constant pair for all five
-    harnesses. The spike's movement guard is retired.
-11. **The record is made transport-visible by naming, not by moving** (q11): it
-    stays at `<agent-dir>/harness-context`, the transport's include list gains
-    both driver records, st2 pins those names in a test, and staging files are
-    written outside the replicated subtree so a temporary name never becomes a
-    durable replicated key.
-12. **Doctor warns, advisory-only** (q10), at or above
-    `HARNESS_CONTEXT_WARN_PERCENT` (80) and on a stale record beside a
-    `running` desired state, never changing its exit status. The threshold is
-    st2's own attention number, documented as not being the harness's
-    compaction point.
-13. **VRS lives in [`08-harness-context/`](../08-harness-context/requirements.md)**
-    (q8), with the roadmap recording the event-driven direction this design
-    deliberately does not take yet.
-
-## Consequences
-
-- The transport's include list must gain both driver records before either
-  replicates. That is a fleet-side change in another repository, so st2 can
-  publish a record it believes remote readers see while they do not; nothing
-  errors. st2's half is a test pinning the names it expects (HC-T08).
-- The already-shipped `harness-state` record is fixed by the same change,
-  without migrating a live record — which is why naming was chosen over moving.
-  `DQ-C11` closes with it.
-- st2 occupying Claude's status-line slot now carries a hard obligation rather
-  than a courtesy: the slot is single-valued, the winner replaces rather than
-  merges, and the st2 materializer writes the winning file, so a tee that does not chain removes
-  the operator's status line on every managed agent (HC-R18). The inverse also
-  holds — a human-set renderer in that file is not preserved by st2's merge —
-  so an operator's renderer belongs in their own settings.
-- A second per-agent record joins `status` and `harness-state`. Two invariant
-  rows change wording when implementation lands: *Stable roster JSON* gains the
-  fourth axis, and *Scoped delivery-input wakeups* gains `harness-context` in
-  its enumeration of records that must never wake a pump.
-- The pinned full-string roster assertions change deliberately, in the change
-  that adds the axis, with the new proof named — the same discipline decision
-  0006 applied to `observedState`.
-- `usedPercent` is not comparable across harnesses as a physical quantity. Any
-  consumer that aggregates it is aggregating operator views, and the ontology
-  pins that.
-- Codex's 12,000 baseline and omp's input-only semantics become version-coupled
-  constants under the omp gate's discipline: a harness bump must re-verify them,
-  and a per-harness fixture pinned to the measured version is what fails if they
-  move.
-- st2 becomes a live producer of a compaction count that tokenlens also derives
-  retrospectively from transcripts. Two sources of truth for one quantity now
-  exist; reconciling them is a tokenlens-side design, not an st2 record change.
-- `rateLimits` under an agent-scoped record repeats across every runtime sharing
-  an account. tokenlens remains the quota authority and nothing here reconciles
-  the two.
-- The Claude producer creates a cross-repo dependency: the st2 materializer owns the
-  `statusLine` slot must not break the operator's own renderer, and the naming
-  of that hand-off is unsettled (`DQ-C2`), as is the settings precedence the
-  design assumes (`DQ-C3`).
-- Bare *context* is already taken in st2's language for R09's working state. The
-  wire key is `context` while the canonical term is *harness context record*;
-  the ontology carries the collision rule.
-
-## Amendment 1 — 2026-08-30: the degraded status-line arm is silent
-
-The chaining obligation (q5, HC-R18) stands unchanged. What is withdrawn is the
-*fallback* the original decision paired with it: that where no downstream
-renderer resolves, the tee passes the payload through unchanged, "transparency
-rather than silence", so the degraded case is still a status line.
-
-That reasoning was wrong for this surface, and observably so. The status-line
-payload is machine JSON, not prose — session id, transcript path, model and
-usage blocks — and the slot repaints every five seconds. A seat that resolves no
-renderer therefore renders a wall of
-`{"session_id":…,"transcript_path":…}` in place of its status line: worse for
-the operator than a blank row, and carrying nothing they can act on.
-Transparency is the right default for a channel a human reads, and the original
-argument applied it to a channel that carries a machine's serialization.
-
-The failure was live rather than theoretical, and was observed on `dev3` on
-2026-08-30. Neither resolution path was present there — the renderer file is managed by the dotfiles
-generation and had not been switched, and the environment variable comes from
-the login-shell session variables while seats launch from a user service — so
-every managed Claude seat on that host displayed raw JSON as its status line.
-
-Amended: where no renderer resolves, and wherever a resolved renderer fails, the
-tee writes nothing to stdout and puts its diagnostic on stderr, which the
-harness routes to its debug log and never to the rendered row. The diagnostic
-names both resolution paths, because absent both is precisely the diagnosis. The
-hook script's own outermost fallback follows the same rule, draining stdin so
-the harness does not take an EPIPE at the refresh cadence.
-
-Recording is untouched by any of this: the reading lands whether or not anything
-is drawn, so the amendment trades no telemetry for the quieter line. Two
-consequences follow. The *Status-line slot chaining* invariant row changes
-wording, and its degraded proofs now assert an empty stdout with the stderr
-diagnostic as their positive evidence — an empty stdout alone is also what a tee
-that crashed instantly would leave. And a blank status line becomes a state an
-operator can reach without an error anywhere; stderr is the only place that says
-why, which is why the diagnostic is required rather than optional.

-# Resource Profiles are state-first read-and-observe capabilities
-
-Status: accepted
-
-Johannes selected this direction through ten recorded interview rounds on
-2026-08-29 and confirmed the combined design before VRS work began. Event-first
-authority remains a separate exploration in [issue #376](https://github.com/compoundingtech/st2/issues/376).
-
-## Context
-
-A Resource Profile maps an opaque Resource URI to a contained local carrier.
-That passive mapping alone cannot observe a remotely changing Resource,
-publish its current state, validate profile-specific attention settings, report
-runtime health, or catch an agent up after delivery was unavailable.
-
-GitHub pull requests and issues make the gap concrete. Mergeability, CI,
-reviews, comments, and lifecycle state change independently. Raw webhook or
-check events can be duplicated, reordered, missed, or noisy, and failed webhook
-deliveries are not necessarily replayed. Existing st2 delivery paths likewise
-do not promise a complete canonical event log. Treating any of those inputs as
-authoritative would claim ordering and replay guarantees the substrates do not
-provide.
-
-Two prototypes bounded the design. A synthetic 16-observation pull-request
-sequence showed that equal-state suppression removed only two candidate wakes,
-while provider-aware semantic filtering reduced the sequence to seven
-actionable or four blocking/terminal wakes. A Rust state-space model then
-checked 97,656 lifecycle sequences and found that storing a pending historical
-digest can point a resumed agent at stale state; one pending-relevance
-condition plus the current snapshot digest is sufficient.
-
-## Decision
-
-1. One atomic current snapshot per Resource binding is canonical. Provider
-   events, polls, webhooks, and demands are observations used to reconcile that
-   snapshot. Notifications are invalidations, not a complete event log.
-2. st2 owns a provider-neutral read-and-observe contract: descriptor execution,
-   selector validation, runtime lifecycle, host-owned publication, health,
-   bounded delivery, and current-state catch-up. Downstream profiles own URI
-   semantics, provider authentication, observation, reconciliation, snapshot
-   schema, semantic topics and facts, and selector defaults.
-3. Descriptor ABI 3 contains the capabilities, selector schema, default
-   selector, published topics, runtime topology, snapshot media type, and
-   snapshot schema identity. A binding may provide validated selector
-   configuration; omission uses the profile default.
-4. `Publication` is the one reusable publication value. It contains schema
-   identity, media type, snapshot bytes, topics, and optional bounded typed
-   facts. Periodic `Publish` and the demanded `Published` result carry that same
-   value through one host acceptance, digest, publication, relevance, and
-   catch-up path.
-5. The profile implementation chooses its provider-native observation
-   mechanism. It may use push, polling, or a hybrid and retains its provider
-   cursor, conditional cache, rate limits, backoff, and repair state. The closed
-   resolver module gains no ambient network or credential imports.
-6. The descriptor declares shared or per-binding runtime topology. Both use one
-   normalized host protocol, directional owner fencing, registration fencing,
-   and the same per-binding publication and delivery state.
-7. Demand observation is an explicit, deny-by-default runtime capability. For
-   an enabled active registration, the host may send `Observe` with a positive
-   demand watermark. The runtime answers that demand with exactly one atomic
-   `ObservationResult` for the same owner, binding, registration, and watermark:
-   `Unchanged`, `Failed` with an optional bounded diagnostic, or `Published`
-   with a `Publication`. There is no separate publication/settlement pair and
-   no host timestamp in the protocol.
-8. Demand is a level-triggered scheduling hint, not a provider-specific
-   reconcile command or provider write. One in-flight dispatch and one latest
-   trailing watermark coalesce bursts without dropping demand that arrives
-   during observation. Exact result, registration replacement, or
-   provider-process failure evidence closes accepted work; clocks do not.
-9. A client wait bound limits only that client's wait. Disconnect or expiry
-   does not cancel accepted demand, retract the supervisor's obligation, or
-   participate in provider scheduling.
-10. When delivery is unavailable, st2 retains the current and last-delivered
-    digests, one pending-relevance condition, and the latest relevant selected
-    topics and facts. Resume emits at most one invalidation for then-current
-    state with that semantic envelope.
-11. Read and observe do not authorize provider mutations. Actions, approvals,
-    and a canonical event log require separate authority, idempotency, audit,
-    and result-delivery designs.
-
-## Options
-
-| Option | Why it was not selected |
-| --- | --- |
-| Canonical Resource event log | Current delivery substrates do not provide complete replay, ordering, retention, cursor recovery, or gap repair. Tracked separately in issue #376. |
-| Hybrid snapshot plus several semantic streams | Provides transition fidelity and independent policies, but adds public stream contracts before notification-volume evidence proves that need. |
-| Keep st2 resolver-only | Existing primitives can be composed downstream, but every profile would reimplement lifecycle, validation, health, catch-up, and publication. |
-| One event or snapshot facet per semantic topic | Enables selective reads but introduces cross-facet consistency and generation lifecycle. One atomic snapshot is sufficient for the evidence-backed use case. |
-| Deliver snapshot bytes in invalidations | Duplicates the canonical carrier, increases delivery size, and weakens the state-first read boundary. Bounded topics and typed facts convey why a current-state read matters. |
-| Preserve every update while delivery is unavailable | Produces a backlog that conflicts with state-first authority and the explicit noise constraint. |
-| Separate `Publish` and demand settlement frames | Allows settlement and publication to disagree or be lost independently. One tagged atomic demand result has one acceptance point and one outcome. |
-| Host-selected observation mechanics | Conflates generic demand with provider-specific reconciliation and transfers cursor, cache, rate-limit, and backoff policy to st2. |
-| Standardize provider actions | No generic action workflow, authority model, approval contract, or idempotency evidence grounds such an API. |

-
-State-first authority makes delivery loss and coalescing safe: reconciliation
-repairs current state, and an invalidation only prompts a read. Provider-aware
-classification is necessary because byte equality cannot distinguish
-actionable failure from routine progress. Binding selectors preserve consumer
-control, while descriptor defaults avoid declaration noise. Host-owned
-publication prevents a network-capable runtime from bypassing containment.
-
-Pending notification is a level condition, not an event identity. If a relevant
-change occurs while delivery is unavailable, a later publication may advance
-the current digest. Catch-up therefore combines pending relevance and its
-bounded semantic envelope with the authoritative current digest rather than
-retaining a historical digest or transition backlog.
-
-The same reasoning governs demand. A watermark identifies host work, not
-provider history. An atomic tagged result cannot race a separate publication
-against settlement, and owner plus registration fencing prevents a replaced
-runtime or binding generation from satisfying current work.
-
-## Consequences
-
-- Descriptor ABI and host-protocol compatibility require conformance fixtures
-  before independently released third-party modules or runtimes are supported.
-- st2 gains a trusted host-process boundary for observable runtimes. The
-  catalog operator, not the wasm guest or Resource URI, selects the executable
-  and its deployed credentials, capabilities, and egress.
-- The built-in `resync` stream carries Resource invalidations keyed by binding;
-  no new stream family or delivery plane is required.
-- Profile implementations may optimize aggressively for native real-time
-  observation, but st2 judges convergent publication, exact demand results, and
-  explicit health. It does not prescribe polling intervals or webhook repair.
-- Actions and event-first authority remain out of scope rather than being
-  smuggled into descriptor or runtime extensibility.

-# Catalog commits and direct edits use independent wake channels
-
-Status: accepted
-
-Requirements change authorized by Johannes on 2026-09-03 through interview decisions Q1–Q3.
-
-## Context
-
-A production `axe agent new` publication waited for the next 30-second supervisor interval. Issue #430 attributed the delay to a timer-only catalog loop, but the exact reported st2 revision already installed the declaration watcher. An isolated test also showed that the watcher receives the atomic directory rename used to publish a new Agent bundle in a small catalog.
-
-The failure is therefore at the declaration notification boundary, not the absence of a catalog event loop. Built-in st2 declaration writers already expose a stronger boundary: after locked publication and readback, each successful transaction atomically advances `.st2/catalog-generation`. Authorized direct atomic KDL replacement does not necessarily use that transaction boundary and must remain prompt.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Independent generation and declaration watchers | Selected | Gives cooperative commits a constant-cost channel while preserving direct atomic authoring. |
-| Durable host-scoped reconcile request | Rejected | Adds a caller and authoring contract, host selection, and a split publish/request failure. |
-| Declaration watcher only | Rejected | Leaves transactional launch latency dependent on the event health of every declaration subscription. |
-| Unix socket or process signal | Rejected | Adds endpoint lifecycle, permissions, PID or socket staleness, and lossy delivery without helping direct authors. |
-
-## Evidence and Argument
-
-The supporting source reads, exact-revision check, caller trace, production
-measurements, and watcher prototypes are recorded in
-[the catalog reconcile wakeup experiment](../.experiments/2026-09-03-catalog-reconcile-wakeup.md).
-The key discriminator is independence: a second watcher instance over one
-control directory does not share the declaration watcher's subscription set or
-backend event queue, while both preserve the existing serialized reconciliation
-owner.
-
-## Decision
-
-The resident catalog supervisor uses two independent filesystem watcher instances that feed the same unit wake channel:
-
-1. A constant-cost watcher subscribes non-recursively to `.st2` and accepts only mutation of `catalog-generation`. This watcher is installed before declaration subscriptions when the control directory exists, revalidates the directory identity after each pass, and reinstalls a stale subscription.
-2. The declaration watcher retains shallow subscriptions to catalog declaration-space directories. It accepts `agent.kdl`, root `catalog.kdl`, `_templates`, and declaration-directory topology mutations while excluding runtime and Resource state.
-
-A callback only queues a wake. The existing single-threaded supervisor owns reconciliation, drains a burst before one pass, and holds the shared catalog lock through discovery and execution. The periodic interval remains the correctness fallback.
-
-Watcher setup and callback failures are operator-visible. Failure of one watcher does not remove the other watcher.
-
-## Consequences
-
-- `st2 agent publish`, catalog apply, and in-place st2 authoring receive a commit-aligned wake after durable publication.
-- Authorized direct atomic Agent Spec replacement retains declaration-event wakeups without a publisher-specific API.
-- The generation watcher has a separate backend queue, so declaration subscription volume or overflow cannot consume its events.
-- The declaration watcher still has cost proportional to declaration-space directory count. This cost is accepted to preserve direct-author behavior; Resource payload depth remains excluded.
-- A public kick command, Unix socket, or caller-side Axe workaround is not part of the contract.
-- The exact reason that the production declaration event was missed remains unproved unless a production-shaped test reproduces it. The independent commit channel removes that unknown from transactional publication latency without mislabeling it as the root cause.
-
-## Evidence required for acceptance
-
-- exact-revision source evidence that the issue revision already had a catalog watcher;
-- a deterministic loop test that direct publication launches an added agent before a long timer;
-- atomic bundle publication coverage at the reported catalog scale;
-- atomic catalog-generation replacement coverage through the independent channel;
-- root `catalog.kdl`, mutation-only, disconnected-channel, and idle no-spin coverage;
-- no new-record diagnostics under strict VRS validation, and the repository Nix check.

-# Immutable agent ID is separate from mutable address and presentation
-
-Status: accepted
-
-Design confirmed by Johannes on 2026-09-05 through the issue #401 interview.
-Alex confirmed the graph-subject model in the design discussion supplied by
-Johannes: the subject keeps a stable ID while its semantic name changes.
-
-## Context
-
-Agent Spec currently makes the positional `identity` serve as logical subject,
-human route, bus address, durable-state key, and task/PTY prefix. `name` and
-`description` can change without disrupting a process, but neither routes.
-
-Quick subject creation happens before the subject has enough context to choose a
-good semantic route. A provisional identity therefore becomes permanent, or a
-later semantic correction creates a new subject and strands its routing,
-runtime, inbox, archive, and context. A representative desired refinement is
-`dev3.dotfiles.fractal.help-key.verifier` to
-`dev3.dotfiles.fractal.keymap.verifier` without changing the logical agent.
-
-PTY provides partial prior art. It separates an immutable session ID from a
-mutable display name, resolves human references through the display name, and
-keeps metadata changes nondisruptive. PTY does not provide the distinct unique
-semantic route required here, nor route history, cross-host identity, or
-catalog transactions.
-
-## Decision
-
-Each logical agent subject has one explicit catalog-global immutable **agent
-ID**. New subjects use UUIDv7. Before ID-aware routing activates, migration adds
-an `id` field to every live and structurally archived legacy declaration. A live
-subject receives its existing host-qualified bus identity, preserving current
-runtime identifiers. An archived subject receives those bytes when unused
-across the combined live-and-archived subject set; an archived collision
-receives UUIDv7 in its declaration and tombstone. Migration also records each
-reassigned legacy bus identity with the subject that kept it and the archived
-subject's new ID, so readers of legacy records never retype colliding bytes
-into the wrong subject. Migration resolves supervisor
-references against the combined pre-migration live-and-archived subject index
-and rewrites every reference to the parent's migrated ID in the same
-transaction. A missing or ambiguous reference refuses before writes and
-requires pre-activation unarchive and repair before retry. A frozen legacy ID
-becomes opaque and remains unchanged after a host move.
-
-An ID survives routing, presentation, graph, host, desired-state, and
-runtime-incarnation changes. Retirement makes a subject non-routable and
-releases its address but preserves its ID. Reintroducing the same ID denotes
-the same subject; a replacement receives a new generated ID.
-
-Agent Spec adds an optional mutable **agent address**. The effective address is
-the explicit value when present and otherwise the positional `identity` value.
-It is unique per logical host among running and suspended subjects;
-`<host>.<address>` is the **bus address** used for ordinary human routing.
-Explicit addresses are bounded dotted lowercase alphanumeric/hyphenated
-segments. The first explicit address atomically replaces the legacy fallback.
-Every later address change is also an immediate cutover. Old addresses receive
-no alias, redirect, history, or expiry period and may be reused.
-
-Ordinary references resolve addresses. Exact ID lookup uses explicit syntax or
-a typed API and never falls through to address lookup. Durable graph edges,
-ownership, authorization, message provenance/replies, and default runtime task
-identity use the immutable ID. Existing declaration-parent state and Resource
-paths do not move. `ST_AGENT` carries the ID as an exact actor selector rather
-than a mutable address.
-
-`name` and `description` remain mutable, non-unique presentation. They never
-route or identify a subject.
-
-Address authoring uses the existing source-preserving, authority-scoped,
-transactional catalog publication model. The complete prospective catalog
-validates catalog-global ID uniqueness and host-local effective-address
-uniqueness, including collisions between explicit addresses and identity
-fallbacks. An address-only change preserves the live process and every durable
-subject surface. Host, graph, and launch changes preserve the logical subject
-ID but retain their field-specific runtime lifecycle.
-
-This decision independently accepts the bounded presentation, constrained
-authoring safety, and nondisruptive PTY projection proposed in draft decision
-0002. It supersedes that draft's claim that positional identity and
-host-qualified bus identity are the sole stable routing keys.
-
-## Consequences
-
-- `new-agent` can create a subject immediately with an opaque durable ID, omit
-  or use a provisional address, then refine its route after the first prompts.
-- Existing live and archived declarations need one additive `id` migration, and
-  supervisor references become ID-keyed in the same transaction. A live subject
-  keeps its former bus identity; only an archived collision receives UUIDv7 to
-  preserve global uniqueness. Runtime and declaration-parent durable state
-  require no re-key. An absent `address` preserves the current route until first
-  assignment.
-- A legacy ID may retain an obsolete host-looking prefix after a host move. Its
-  type, not its string shape, distinguishes it from a current bus address.
-- A host move does not change logical subject identity or default task identity,
-  although the process incarnation can still change under the host lifecycle
-  contract.
-- Stale human routes fail loudly. The system does not accumulate compatibility
-  aliases or make correctness depend on time.
-- The implementation must change every identity-bearing boundary coherently;
-  the open implementation delta prevents the target VRS from being mistaken for
-  shipped behavior.
-
-## Amendment 1 — 2026-09-05: the address ships first, the ID half is staged
-
-The decision above stands as the target. Its two halves ship separately, because
-only one of them answers the Context: the mutable address does, with no
-migration, no record version, and no activation gate. Splitting a provisional
-route from a durable key needs one new field; freezing an explicit ID buys
-host-move invariance and live/archive collision attribution, both real and both
-with no observed instance on any admitted host.
-
-Shipped now: the optional `id` and `address` grammar with catalog-global `dup-id`
-and host-local `dup-address` admission, `effective_id`/`effective_address`/
-`bus_address`, roster and graph projection, `st2 agent address`, and the
-fail-closed bare-or-qualified reference resolution — which every reference plane
-now shares, including stream ingress. Positional `identity` remains the durable
-key, so `ST_AGENT`, task IDs, session socket paths, declaration-parent state,
-harness records, PTY tags, and supervisor edges are untouched by a cutover. A
-`supervisor` value is a declaration key on both of its planes — the org-chart
-walk and the notices that walk carries (crash-loop, protocol rejection) — so an
-address is a routing alias for human and message references only, never a
-supervisor reference.
-
-Deferred: UUIDv7 creation, the `st2 catalog migrate-ids` freeze transaction,
-ID-keyed durable records (message version 2, harness-state and harness-context
-version 2, PTY schema 2), collision metadata and collision-aware attribution of
-reassigned legacy endpoints, and the activation gate that would sequence them.
-No part of it is contradicted by shipping the address first: `id` and `address`
-are independent fields, and the freeze migration is unchanged by their order.
-
-The ID half re-enters on any one of these observations, each of which turns a
-latent argument into a live obligation:
-
-- a completed cross-host seat move, or a concrete plan for one — the frozen ID is
-  the only thing that preserves `ST_AGENT`, task IDs, and socket paths across it;
-- a live/archive identity collision on any admitted host, which is what the
-  reassignment record and legacy-endpoint attribution exist for; or
-- a UUIDv7 creation call site — a generator that authors new subjects — because a
-  subject whose ID is in no address namespace cannot be reached without ID-keyed
-  resolution.
-
-Two corrections to the premises this decision was implemented against:
-
-- **Version-1 readers are additively tolerant, so a new field is not a version
-  bump.** `crates/fractal-wire/src/lib.rs` states the opposite of the assumption as
-  policy: no type in the reader crate uses `deny_unknown_fields`, precisely so a
-  reader older than the binary it shells out to ignores unknown fields. The one
-  genuine cross-build hazard is single-field and about routing, not records: a
-  build that does not read `address` routes the positional identity and refuses
-  the new address, the exact inverse of a build that does. So the reader-first
-  obligation is "deploy an `address`-reading build on every admitted host before
-  authoring any address", and nothing more. A durable record that *does* reject
-  unknown fields — `SentRecord` — keeps its version-1 shape here, so its version-2
-  reader belongs with the writer that emits one.
-- **Ownership keys are not addresses.** An exact selector answers to either
-  immutable key: the explicit `id`, or the positional `<host>.<identity>` bus
-  identity that migration would freeze into it. Both are unique by admission and
-  neither moves when an address does, which is what keeps a running seat, its
-  resync stream, and an interrupted send bound to their own subject across a
-  cutover.
-
-Before the ID half can land, two defects found while auditing its
-implementation must be fixed:
-
-- `supervisor_chain::resolve_spec` resolves parents by `bus_id(host)` or bare
-  `identity` only, so it must accept `effective_id`; otherwise a subject born with
-  UUIDv7 loses its org-chart edge, which is the clause the migration transaction
-  exists to satisfy;
-- `st2 catalog migrate-ids` must exempt `agent-id-missing` from its own
-  pre-admission gate. A partially migrated catalog is inadmissible by that
-  diagnostic, and the migration verb refuses to write into a non-admitting
-  catalog, so the rollout order the decision prescribes — teach the projection to
-  emit `id`, then migrate — deadlocks on the only command that can clear it.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Immutable ID + distinct mutable unique address + non-unique presentation | Selected | Matches the graph-subject and Git-branch-alias model and permits semantic route refinement without re-keying continuity. |
-| Existing host-qualified bus identity as explicit legacy ID | Selected | Preserves current state and distinguishes valid same-identity subjects on different hosts; the original host prefix becomes opaque after migration. |
-| PTY two-axis model: use non-unique `name` as the route | Rejected | It removes a field but does not provide the distinct mutable unique semantic address Johannes requires. |
-| Keep exact ID and address in one precedence-based positional resolver | Rejected | Existing semantic IDs would keep old route spellings alive after cutover, contradicting immediate rename semantics. |
-| Preserve old addresses as aliases | Rejected | Adds permanent reservation, removal, collision, and compatibility obligations without a stale-caller requirement. |
-| Re-key legacy state to UUIDv7 | Rejected | Requires an unproved live migration of task/PTY, inbox, archive, context, provider, and external-reference state. |
-| Require `address` in every declaration immediately | Rejected | Creates a cross-repository flag day and mixed-version deployment hazard; optional fallback is additive. |
-| Current host-qualified placement as mutable ID | Rejected | Makes a host move change the logical graph subject identity; the selected legacy ID instead freezes the original bytes. |
-| ULID or custom random token for new IDs | Rejected | UUIDv7 is standardized and the ID is not the ordinary human-facing route, so compactness does not justify a custom identity format. |
-
-## Evidence and Argument
-
-Evidence gathered on 2026-09-04 and 2026-09-05:
-
-- issue #401 records the current overloading and a disposable-catalog continuity
-  experiment;
-- PTY PR #139 proves immutable-ID-first resolution, duplicate human labels, and
-  fail-closed ambiguity diagnostics; PTY PR #142 proves atomic exact-ID metadata
-  projection;
-- st2 `message::resolve_agent_handle` already uses catalog-generation fencing;
-- R27 catalog authoring already provides complete prospective validation,
-  compare-and-swap publication, durable generations, and crash fencing;
-- Johannes confirmed the graph-subject/branch-alias scenario and q1-q12, then
-  selected frozen existing bus identities for colliding legacy IDs in q13.
-
-Implementation acceptance requires model-free tests that prove: UUIDv7 creation,
-explicit-ID migration for live and archived declarations, deterministic archived
-collision handling, atomic supervisor reference migration, catalog-global ID
-uniqueness across the live catalog and archive, optional-address parsing and
-legacy fallback, host-local effective-address collisions, explicit ID versus
-ordinary address selection, dotted-reference disambiguation including
-host-pinned qualified input, immediate old-address failure and reuse, retirement
-release, ID-safe unarchive, and safe reactivation; atomic cutover under
-concurrent readers/writers, constrained self/supervisor authoring, and Nix
-refusal; unchanged task/PTY PID, creation identity, generation, provider
-session, inbox, archive, context, Resource state, declaration-parent state paths,
-and existing long-form task IDs after address changes; retained subject ID with
-existing lifecycle behavior for host/graph/launch controls; message-version
-reader-first compatibility, including collision-aware attribution of legacy
-endpoints whose bytes migration reassigned, and typed non-Agent endpoints; and
-stable machine-readable roster, graph, task, message, and diagnostic shapes.

-# Systemd scope wrappers disable environment expansion
-
-Status: accepted
-
-Accepted on 2026-09-05 for R42 launch argv transparency.
-
-## Context
-
-The runtime adds `systemd-run` around every PTY and exec launch when Linux systemd
-scope isolation is available. Rust passes the task program and arguments to
-that outer process as opaque OS strings, but `systemd-run` performs its own
-command-line environment expansion by default. A Linux systemd 260 experiment
-passed the literal `$HOME:${UNSET}:$$` through the wrapper and observed `$$`
-changed to `$`. The wrapper therefore did not preserve launch argv even though
-st2 itself never invoked a shell or edited the argument.
-
-The scope wrapper is also the mechanism behind control-plane replacement
-safety. Any correction must retain scope creation, collection, inherited I/O,
-PTY behavior, exit status, and outliving-child membership.
-
-## Options
-
-| Option | Tradeoffs |
-| --- | --- |
-| Disable systemd expansion before the separator — selected | Preserves the original OS strings without changing scope mechanics. |
-| Keep systemd's default expansion | Rejected because the live probe changed caller-owned argument data. |
-| Rewrite dollar signs into systemd escape sequences | Rejected because st2 would have to interpret every OS string and maintain a wrapper-specific transform. |
-| Shell-quote the inner command | Rejected because there is no shell boundary; quote bytes would become task argument bytes, while adding a shell would introduce evaluation. |
-| Drop systemd scope isolation for affected commands | Rejected because it would trade argument corruption for violation of R11 control-plane replacement safety. |
-
-## Evidence and Argument
-
-The Linux systemd 260 experiment distinguished the wrapper's default from the
-selected option with one literal input. Default expansion changed the terminal
-`$$` in `$HOME:${UNSET}:$$` to `$`; `--expand-environment=no` preserved the
-complete input. With expansion disabled, non-TTY argv and standard descriptors,
-real-PTY terminal status, exit propagation, outliving-child scope membership,
-collection, exact-name reuse, and cleanup all retained their prior behavior.
-
-The option is the narrowest boundary fix: systemd owns the unwanted
-interpretation, and systemd exposes a switch that removes it. Rewriting task
-arguments inside st2 would replace downstream interpretation with an
-st2-maintained encoding and would no longer be opaque launch argv.
-
-## Decision
-
-All scopes use the fixed description `st seat`. A generated description embeds
-argument bytes in a D-Bus string, which rejects non-UTF-8 arguments before
-the task executes. Keeping the description separate preserves opaque argv.
-
-Linux scope launches on systemd v254+ use this exact outer argument order:
-
-```text
-systemd-run --user --scope --collect --quiet --no-ask-password --unit=<unit> "--description=st seat" --expand-environment=no -- <program> <arg>...
-```
-
-On systemd v236–253, omit only `--expand-environment=no`. These versions
-execute scope arguments directly and do not support that option. The version
-probe must succeed, and the user manager must answer before selecting scope
-isolation. Unknown or unsupported versions keep degraded isolation.
-
-The [systemd v249 scope implementation](https://github.com/systemd/systemd/blob/v249/src/run/run.c)
-passes `arg_cmdline` directly to `execvpe`; neither percent nor dollar bytes
-need escaping. Doubling either byte would corrupt literal arguments. The
-[systemd v254 implementation](https://github.com/systemd/systemd/blob/v254/src/run/run.c)
-introduces the expansion option, so newer launches explicitly disable it.
-
-`--expand-environment=no` is passed as a `systemd-run` option before the `--`
-separator. st2 appends the program and each argument after the separator as the
-original OS strings. It does not quote, escape, expand, or render those values
-through a shell. Detached and degraded-detached modes remain direct
-pass-throughs.
-
-## Consequences
-
-- Dollar-bearing literals, including `$HOME`, `${UNSET}`, and `$$`, reach PTY
-  and exec tasks byte-for-byte in scope mode.
-- The systemd option sequence is part of the tested wrapper contract; the only
-  version-dependent option is the expansion-disable option before the
-  separator. All launches disable password prompting.
-- macOS and Linux hosts without usable user scopes keep the existing direct
-  program-and-argv path.
-- Scope lifetime and I/O behavior are unchanged. The supporting live evidence
-  is recorded in the [systemd scope argv experiment](../.experiments/2026-09-05-systemd-scope-argv-transparency.md).
-
-The [systemd 249 compatibility experiment](../.experiments/2026-10-08-systemd-249-scope-compatibility.md)
-records legacy option rejection, exact raw argv and inherited execution context,
-sibling-scope survival, unreachable-manager fallback, and a native driver seat
-reply before and after daemon service restart. Its supplied-runtime boundary
-is explicit; native stock Ubuntu 22.04 installation is not established.
-
-## Amendment 1 — 2026-10-08
-
-Launch environment values were passed on process command lines, where service
-managers and process listings can record them. The launchers now export the
-resolved environment to the PTY process and pass only `--env NAME`. PTY resolves
-each name from that inherited environment and persists the resolved overlay
-for restart. The shared `PTY_PLACEMENT_ENV` set owns `PTY_ROOT` and the deprecated
-`PTY_SESSION_DIR`: the canonical runtime root wins after the overlay, and the
-legacy variable is removed (also from inherited environments). Declared legacy
-placement receives a value-free, name-only diagnostic. Other resolved
-environment precedence remains unchanged.
-
-Captured launcher output can echo environment values. It is classified privately;
-launch failure reasons expose a closed diagnostic kind plus exit status rather
-than copying stdout/stderr into replicated claims and claim-trace output.
-Kinds are `launcher-incompatible`, `placement-conflict`, `session-in-use`,
-`spawn-failed`, and `unknown`; the implementation specification records their
-matching signatures and priority. The older name-only-rejecting launcher is
-therefore distinguishable from other exit-1 failures without exposing its text.
-No raw-output file or journal sink is added.
-
-The fixed `--description=st seat` already keeps the command line out of the
-unit description, so this amendment adds no scope description of its own and
-leaves the outer argument order above unchanged.
-
-This removes environment values from generated environment arguments, not from
-explicitly authored argv or tag expansions. Seat-declared
-environment values stored in replicated graph claims remain a known exposure
-outside this amendment's fix.
-
-Evidence: launcher environment/argv regression tests, runtime-selected registry
-precedence with declared canonical/legacy placement controls, and sentinel-bearing
-failed launchers with value-free reasons.
-R42's ratified requirements text is unchanged.

-# Task resource targets are strict observations
-
-Status: accepted
-
-Accepted on 2026-09-05 for R23 fail-closed task inventory.
-
-## Context
-
-A downstream sampler needs to attribute host CPU and memory observations to a
-running st2 task every 15 seconds. st2 already has the authoritative read-only
-join between desired tasks and observed PTY or exec generations, but its
-version-1 inventory exposes only process metadata. Linux sampling is truthful
-at the task boundary only when it uses the live process's unified cgroup-v2
-membership. Systemd unit names, scope names, and task naming conventions are
-not observations of that membership. Darwin has no equivalent cgroup locator;
-a process-tree walk rooted at the observed PID is necessarily best effort.
-
-The locator can disappear or change while it is read. PID alone cannot reject
-reuse, and retaining scope membership in st2 would add a second state plane
-whose lifecycle could diverge from the backend and kernel.
-
-## Options
-
-| Option | Tradeoffs |
-| --- | --- |
-| Add a required strict tagged target to task-inventory v2 — selected | Makes every row self-describing, represents degradation explicitly, and lets the sampler remain downstream. |
-| Derive Linux targets from systemd unit names | Rejected because direct/degraded launches and cgroup migration make the name an untruthful proxy for current membership. |
-| Add optional or nullable locator fields | Rejected because absence cannot distinguish non-running, indeterminate, unsupported, raced, and degraded observations. |
-| Persist a runtime-ID-to-scope registry in st2 | Rejected because it creates stale ownership and reconciliation obligations without improving kernel evidence. |
-| Sample and export resource metrics from st2 | Rejected because cadence, retention, and metric transport belong to the downstream observer, not the task control plane. |
-
-## Evidence and Argument
-
-The focused experiment separated strict cgroup parsing from the
-process-generation fence. One exact unified `0::` entry preserved its
-slash-prefixed path, including spaces and colons, while absent, duplicate,
-relative, repeated-separator, trailing-separator, and traversal-capable shapes
-were rejected. Stable start-token observations admitted the candidate target.
-A deterministic PTY regression replaced the PID generation between the
-registry snapshot and start-token capture; the socket-backed stats row's
-changed creation generation rejected that token. A two-live-task fixture
-proved one unscoped stats snapshot serves the whole inventory. A token mismatch
-before target read, a token change after it, and process exit each emitted only
-a bounded unavailable result and never the candidate locator.
-
-A live Darwin exec observation joined the current PID as
-`darwinProcessTree.rootPid` without rewriting its retained generation record,
-and a real PTY replacement changed generation identity while retaining the
-same resource-target wire contract. The complete task-inventory unit and CLI
-integration surfaces preserved absence, indeterminate, park, timeout,
-declaration-drift, and read-only behavior.
-
-This evidence favors a required tagged union over nullable fields: each sample
-states both whether a locator exists and why it does not. Reading kernel
-membership is also strictly stronger than reconstructing it from unit naming,
-while keeping sampling downstream avoids adding lifecycle and retention state
-to st2.
-
-## Decision
-
-`st2 tasks --json` advances to `st2.task-inventory.v2`. Every runtime object has
-one `resourceTarget` internally tagged by `type`:
-
-- `{"type":"linuxCgroupV2","path":"/<exact-unified-path>"}`;
-- `{"type":"darwinProcessTree","rootPid":<pid>}`; or
-- `{"type":"unavailable","reason":<bounded-reason>}`.
-
-Unavailable reasons are exactly `notRunning`, `runtimeIndeterminate`,
-`processUnavailable`, `generationChanged`, `cgroupV2Unavailable`, and
-`unsupportedPlatform`.
-
-On Linux, st2 reads exactly one unified `0::<path>` entry from the observed
-process's `/proc/<pid>/cgroup`. Exec compares the target fence to the token in
-its generation record. PTY captures each candidate daemon token after the
-registry snapshot, then takes one unscoped, socket-backed `pty stats --json`
-snapshot for the entire inventory. A candidate is admitted only when its named
-live stats row reports the same daemon PID and creation generation and a second
-token read is unchanged; that admitted token then fences the target read. A
-missing, exited, or recycled process never publishes the candidate locator.
-Darwin fences the current process in the same way before exposing its PID as a
-best-effort tree root. All targets are rediscovered on each inventory command.
-
-Runtime ID remains stable task identity. PID, creation time, generation ID,
-cgroup path, root PID, unit, and incarnation remain observation locators only.
-
-## Consequences
-
-- A downstream 15-second sampler can consume one versioned inventory without
-  parsing scope names or asking st2 to sample metrics.
-- Resource degradation is bounded and machine-readable while the inventory's
-  existing fail-closed catalog/runtime semantics remain intact.
-- The Linux path is slash-prefixed and relative to the cgroup-v2 mount; `/`
-  denotes the mount root.
-- The runtime adds no persistent locator registry, metrics server, sampling cadence, or
-  resource history.
-- Version-1 strict consumers must explicitly adopt schema version 2.
-- Evidence is recorded in the [task resource target experiment](../.experiments/2026-09-05-task-resource-target-observation.md).

-# st2 owns the direct actor lifecycle
-
-Status: accepted
-
-Accepted on 2026-09-25 for R47 published actor resource roots and R48 direct
-actor archival.
-
-## Context
-
-A direct OMP session runs without a declaration. Its entrypoint derives
-`ST_AGENT=<host>.direct.omp.<encoded-pty-id>` from `PTY_SESSION`, and writers
-lazily create `agents/<host>/direct.omp.<encoded-pty-id>/` in the live catalog.
-Nothing ever removed those directories: they have no declaration, so they can
-never be retired, and the retired-seat archive step never saw them. Every
-direct session ever started therefore stayed in the live catalog, and catalog
-viewers had to guess where one actor ended and the next began.
-
-Three facts bear on who should remove them. st2 already owns the structural
-archive (`st2 catalog archive`/`unarchive`, tombstones, the `archive-after`
-grace period, the 25-per-pass bound, and the exclusive authoring lock). The
-supervisor pass already lists the catalog's effective PTY registry. The
-direct entrypoint, by contrast, runs only while its session is alive, so it
-cannot observe its own death.
-
-Liveness has several tempting proxies: directory mtimes, the newest file under
-`resources/`, harness activity records, or matching PTY names against the
-identity. Each can be wrong in both directions. A long-idle live session has
-old mtimes. A synced or restored directory has fresh ones. PTY names are not
-unique, and a session ID can be a prefix or substring of another.
-
-## Options
-
-| Option | Tradeoffs |
-| --- | --- |
-| st2's supervisor archives dead direct actors through the existing archive — selected | Reuses one reversible mechanism, lock, grace period, and bound; the registry read is already in the pass; no new owner or state plane. |
-| The direct entrypoint cleans up its own directory on exit | Rejected because a crashed, killed, or host-rebooted session never runs its exit path, and deleting on exit is irreversible. |
-| A separate sweeper outside st2 | Rejected because it would duplicate the archive, lock, ledger, and registry read, and race `st2 catalog apply` without st2's authoring lock. |
-| Liveness from mtimes, activity, or name matching | Rejected because each proxy misjudges idle-live and restored-dead actors, and a wrong verdict moves a live actor's state out from under it. |
-| Delete dead directories instead of archiving | Rejected because deletion is irreversible; retention is a separate question. |
-
-## Evidence and Argument
-
-The strict PTY segment codec makes the directory name alone yield the exact
-PTY session ID: a PTY-generated eight-character ID is its own segment, every
-other valid ID is `x-` plus its lowercase hex bytes, and only the canonical
-encoding decodes. That gives one exact join key into the registry, so the
-liveness verdict is a lookup, not an inference. A unit test pins that a
-running session whose ID merely contains an actor's ID does not keep that
-actor alive, and that an exited record is the same as an absent one.
-
-A first-observation ledger is needed because st2 records no timestamp when a
-session dies, exactly as for retirement. Dropping a row when the PTY runs
-again, and when the actor is selected for archival, errs toward keeping
-actors live: a restart, a failed move, and an unarchive each start a fresh
-grace period. The supervisor integration suite
-(`tests/supervisor_auto_archive.rs`) covers grace expiry for exited and absent
-records, a stale row dropped for a running PTY, a first-observed death
-serving its own grace period, a byte-identical whole-directory move with the
-decoded PTY ID in the tombstone reason, and unarchive without immediate
-re-archival.
-
-Publishing each actor's resource root in the graph removes the viewer's need
-to infer subject boundaries, and the same discovery feeds both publication and
-archival, so the two cannot disagree about what a direct actor is.
-
-## Decision
-
-st2 owns the direct actor lifecycle. `st2 catalog graph --json` publishes
-`resourceRoot` for every agent and a `directActors` list, additively within
-`st2.catalog-graph.v2`. The supervisor's archive step archives local direct
-actors whose PTY session has had no running record in the catalog's effective
-PTY registry for `archive-after`, measured from first observed death in
-`.st2/direct-dead-observed.json`, after retired seats and within the same
-per-pass bound, as a reversible rename plus tombstone. Liveness uses only the
-decoded PTY ID and exact registry records; mtimes, activity, and names never
-decide it.
-
-## Consequences
-
-- The direct entrypoint needs no exit hook, and a crashed session is archived
-  like a cleanly exited one.
-- A direct actor on another host is never judged, because that host's
-  registry is not observable; its own supervisor archives it.
-- A PTY registry that loses a live session's record makes that actor look
-  dead; the grace period and reversible unarchive bound the cost.
-- `st2 catalog archive` stays declaration-only; the supervisor step is the
-  only path by which a direct actor leaves.
-- Archival moves bytes without reclaiming them. Retention of archived
-  identities is open as spec DQ6
-  ([#530](https://github.com/compoundingtech/st2/issues/530)).

-# DELTA-002: typed request transport is design-superseded but still shipped
-
-Status: open
-
-## Divergence
-
-[Decision 0004](../.decisions/0004-stream-events-are-a-distinct-record-kind.md)
-absorbs the typed service-principal request/reply transport into stream events
-plus ordinary message replies. The implementation (`src/request.rs`, the
-`st2 request` command group, `resources/request-state`) and its normative spec
-sections (root [Service-principal request transport](../spec.md), 03-message
-[Typed requests](../03-message/spec.md)) remain fully in force. Docs now carry
-an accepted direction the code does not yet implement.
-
-## VRS
-
-The accepted target is stated in decision 0004 and staged as
-[04-stream DQ-S4](../04-stream/open-questions.md): a reply to an event is an
-ordinary `message reply`; `pending | replied` derives from `in-reply-to`;
-`MESSAGE-R11`'s separation purpose survives because events never write the
-sender ledger. A stream-qualified producer identity does not currently resolve
-to an agent or service-principal mailbox, so ordinary reply routing is still
-an explicit design and implementation gap (04-stream DQ-S1). The superseded
-sections carry forward-pointers to this delta.
-
-## Implementation
-
-`src/request.rs` is untouched and its invariant row (**Idempotent service
-requests**, `tests/request_cli.rs`) is green and load-bearing. Two hard
-constraints for the retirement, both verified during exploration: the request
-wire types carry `deny_unknown_fields` and cannot evolve in place (fresh
-namespace, not migration), and `request-state` dedup receipts are retired, not
-converted — an announced loss after a deprecation window. The eval-owned
-external requester capability (`MESSAGE-A01`) must keep a working path
-throughout. The typed request surface must not enter deprecation until an
-event reply reaches a real producer endpoint end to end.
-
-## Direction
-
-update implementation
-
-## Resolution Signal
-
-Staged, in order: (1) stream events land with their own invariant proofs;
-(2) a routable event-producer reply endpoint and reply-derived status land
-with an end-to-end proof preserving `MESSAGE-A01`; (3) the **Idempotent service
-requests** row is re-pointed to those replacement proofs in the same commit
-that starts the `st2 request` deprecation window
-(`qualified_proof_references_resolve` enforces the ordering); (4) after the
-window, `src/request.rs` and `request-state` writes are removed, the superseded
-spec sections are deleted, and `MESSAGE-R11` is re-worded to its surviving
-form. Close this delta at step 4 with the exact removal commit recorded.

-# DELTA-003: the immutable subject ID is not implemented
-
-Status: open
-
-Narrowed by [0015 Amendment 1](../.decisions/0015-immutable-agent-id-and-mutable-address.md)
-on 2026-09-05: the mutable address shipped, the immutable ID is staged behind the
-triggers that amendment names.
-
-## Divergence
-
-[Decision 0015](../.decisions/0015-immutable-agent-id-and-mutable-address.md)
-and root requirements R19 and R24-R26 define the accepted target identity
-model. `AgentSpec` now admits an optional `id` and an optional `address`;
-`st2 agent address` authors the route; ordinary references, inbox and status
-selection, recipients, and stream ingress all resolve through the fail-closed
-bare-or-qualified address algorithm; roster and graph publish `id`, `address`,
-and `busAddress`.
-
-What remains divergent is the ID half. No writer emits `id`, so the effective ID
-of every subject is still its positional `<host>.<identity>` bus identity, and
-that value — not an explicit ID — is what ownership keys, task prefixes, durable
-record endpoints, supervisor edges, PTY tags, and `ST_AGENT` carry. A subject
-created after this delta closes would need UUIDv7 and ID-keyed resolution to be
-reachable at all.
-
-## VRS
-
-The target has an explicit catalog-global immutable agent ID, an optional
-host-local mutable agent address, a derived bus address, and separate non-unique
-presentation. Migration freezes every live legacy subject's existing
-host-qualified bus identity without moving declarations or declaration-parent
-state. A structurally archived subject freezes the same bytes when they remain
-unique across the combined live-and-archived set; an archived collision receives
-UUIDv7 in its declaration and tombstone. Migration also records every
-reassigned legacy bus identity with the subject that kept it and the archived
-subject's generated ID, so a tolerant reader never retypes colliding
-version-1 bytes into the wrong subject. Supervisor
-resolution uses the combined pre-migration live-and-archived subject index; the
-same migration rewrites every reference to the parent's migrated ID. A missing
-or ambiguous reference refuses before writes with
-`legacy-supervisor-unresolved`; the operator must unarchive and repair that
-declaration through the pre-activation legacy authoring path, then retry.
-Positional `identity` remains the legacy address fallback until an explicit
-address is assigned. Address assignment is an immediate route cutover with no
-alias or history. Exact ID selection is explicit and ordinary references use
-the fail-closed bare-or-qualified address algorithm.
-
-Agent endpoints persist an immutable ID plus a publication-time address
-snapshot. Principal and external endpoints persist an explicit endpoint kind
-and canonical typed address instead of pretending that address is an agent ID.
-That is a new durable record version for `SentRecord`, which rejects unknown
-fields (`src/message.rs`). It is not one for harness-state or harness-context,
-whose readers ignore unknown fields by policy
-(`crates/fractal-wire/src/lib.rs`) — the premise that strict version-1 readers reject
-additive fields was wrong for every record but the sender ledger, and each
-version-2 reader belongs in the pull request that adds the writer emitting it.
-
-## Implementation
-
-The address half is implemented. What it leaves is the ID half, and it must
-propagate one typed ID distinction through:
-
-- live and archived catalog validation, explicit-ID migration, unarchive, and
-  ID-keyed supervisor references — `supervisor_chain::resolve_spec` resolves a
-  parent by `bus_id(host)` or bare `identity` only, so it must accept
-  `effective_id` before a UUIDv7-born subject can hold an org-chart edge, and
-  `st2 catalog migrate-ids` must exempt `agent-id-missing` from its own
-  pre-admission gate or the prescribed rollout order deadlocks;
-- every ambient `ST_AGENT` consumer, generated hook, channel adapter, and driver
-  argument, which today carry the positional bus identity;
-- runtime ownership, default task IDs, task inventory, socket admission, PTY
-  schema-2 metadata, and launch metadata while keeping declaration-parent state
-  and Resource paths stable;
-- version-2 Sent records, typed non-Agent endpoints, DING sender projection,
-  stream and resync ownership keys, harness-state, and harness-context records;
-  and
-- all supported downstream evals and generators.
-
-The remaining reader-first obligation of the shipped half is single-field and
-about routing: a build that does not read `address` routes the positional
-identity and refuses an authored address, so an `address`-reading build must be
-deployed on every admitted host **before** any address is authored. That is
-satisfied by the release carrying the grammar; no record version, downstream
-reader survey, or catalog transaction is implied by it.
-
-Activating the ID half is still a reader-first transition, not a one-version flag
-day:
-
-1. Deploy readers that accept legacy and target Agent Specs, message versions 1
-   and 2, and PTY schemas 1 and 2. Keep every writer on legacy output. The
-   harness-state and harness-context readers are additively tolerant already, so
-   their version-2 arms ship with their writers rather than ahead of them.
-2. Prove reader readiness on every admitted host and supported downstream
-   consumer. An unreadable or unknown reader is not ready.
-3. In one catalog transaction, add migrated unique IDs to live and structurally
-   archived declarations, update archived tombstones, and rewrite every
-   supervisor reference to its already-resolved migrated ID.
-4. Re-prove reader readiness immediately before enabling target writers.
-5. Activate UUIDv7 creation, raw-ID `ST_AGENT`, ID-keyed runtime ownership,
-   message version 2, harness-state and harness-context version 2, and PTY
-   schema 2 together.
-
-No timeout substitutes for readiness. Until step 5 completes, the positional bus
-identity remains the normative durable key and every current invariant remains
-normative implementation behavior. After activation, an unmigrated archived
-declaration cannot re-enter the catalog; unarchive validates ID uniqueness, and a
-transition from retired to routable validates full-catalog address uniqueness.
-
-## Direction
-
-update implementation
-
-## Resolution Signal
-
-Close this delta only after the canonical Agent Spec requires `id` and accepts
-`address`, all live and archived legacy subjects have explicit migrated IDs and
-ID-keyed supervisor references, st2 and all supported downstream generators emit
-and consume the new model, and the model-free proof corpus passes against an
-immutable st2 artifact. The proof must cover UUIDv7 creation, legacy bus-ID
-migration, global uniqueness, address fallback and grammar, dotted
-bare/qualified disambiguation including host-pinned qualified input, host-local
-address uniqueness, explicit ID selection, immediate address cutover and reuse,
-retired-address release and reactivation validation, transactional concurrency,
-authority and Nix refusal, nondisruptive live continuity, readable
-message/DING sender projection and cosmetic fallback, version-1 record
-compatibility including collision-aware legacy attribution, harness-state and
-harness-context version-2 records read by tolerant readers, typed non-Agent
-endpoints, host/graph/launch lifecycle controls, and every public machine wire
-shape named by decision 0015-immutable-agent-id-and-mutable-address.
-
-Update these load-bearing invariant rows and their named tests in the same
-implementation:
-
-- `Runner-owned task identity`, including its PTY actor-tag clause, from
-  host-qualified `ST_AGENT` and schema-1 `agent.actor.path` to raw immutable ID
-  and schema-2 `agent.actor.id` plus `agent.actor.address`;
-- `Stable roster JSON` for appended immutable ID, nullable current bus address,
-  presentation, and migrated supervisor projection;
-- `R23 fail-closed diagnostic inventory` for ID-keyed ownership and nullable
-  address without weakening completeness;
-- `Archival leaves the live catalog` for frozen archived IDs and safe unarchive;
-  and
-- `Unbindable session sockets fail at admission` for the new default task-ID
-  shape and preserved legacy socket continuity.
-
-Record the exact release, rollout evidence, and eval artifact here when closing.

-# DELTA-005: `costUsd` is harness-reported at its reported scope
-
-Status: resolved — HC-R16 wording confirmed by Johannes (axe Q168, 2026-10-07 ~20:45Z)
-
-## Divergence
-
-HC-R16 originally required "session cost", contradicting the values pi and omp
-report. Johannes confirmed the amendment to "the harness-reported cost at the
-scope the harness reports, stated per harness in the spec producer table"
-(axe Q168, 2026-10-07 ~20:45Z); the accepted requirement now matches the
-producer scope and this delta is resolved.
-
-The pi and omp producers shipped on 2026-08-29 publish the **last assistant
-message's** `usage.cost.total`, which is what those two harnesses actually
-report.
-
-The other three harnesses are not affected: Claude's `cost.total_cost_usd` and
-OpenCode's `session.info.cost` genuinely are session totals, and Codex reports no
-cost at all.
-
-## VRS
-
-The producer table already named per-message `usage.cost.total` for pi and omp.
-The confirmed HC-R16 wording allows harness-specific scope and makes the
-requirement and producer rows consistent; the pi and omp producer sections
-describe the actual published values.
-
-## Implementation
-
-Turning pi's or omp's per-message cost into a session total means summing every
-message's `usage.cost.total` in the producer. That is precisely the
-producer-side accumulator HC-R16 already refuses one field over, for
-`sessionTotalTokens`, and the reasoning transfers unchanged: the sum's
-correctness depends on having observed every message, an extension loaded into a
-session that is already running has not, and a half-observed total is a worse
-answer than an honest smaller one. Nothing else in st2 reconciles this number —
-HC-R16's "carried as what the harness reported and nothing more" is the binding
-half of the requirement, and a fabricated sum would violate it in order to
-satisfy the word "session".
-
-The alternative — writing `null` — was rejected because the per-message figure
-is real, is what pi and omp show their own operators, and is strictly more
-information than nothing.
-
-One consequence is load-bearing in the implementation and is documented in the
-producer sections: because the record replaces a reading's fields wholesale,
-a frame emitted from an event that carries no cost would *erase* the published
-one. The extension holds the last assistant cost and restates it on every frame,
-and clears the hold on session replacement.
-
-## Direction
-
-update VRS
-
-## Resolution Signal
-
-Resolution: HC-R16 and the spec field description now state that cost is
-harness-reported at the scope the harness reports, stated per harness in the
-producer table. Johannes confirmed the protected requirement change in axe Q168
-(2026-10-07 ~20:45Z). Consumers must read the `harness` discriminator before
-comparing this field across harnesses — already required for `usedTokens`, whose
-meaning differs between pi and omp for unrelated reasons (HC-T03).

-# DELTA-006: the pre-ledger `delivery-state.json` boundary arm outlives its own necessity
+# DELTA-006: retained native delivery-state translation
 
 Status: open
 
-## Divergence
+The canonical ledger owns `st.delivery-ledger.v1`.
+`crates/fractal-drivers/src/delivery_ledger.rs` calls
+`migrations::delivery_state::recover` only from `Ledger::open`'s missing-ledger arm.
+The translation reads a pre-ledger `delivery-state.json` and carries its in-flight
+attempt as asserted evidence. It authorizes no resend or stronger observed receipt.
+This remains reachable from Fractal's native Codex and OpenCode drivers after the
+catalog CLI retires.
 
-The canonical delivery ledger owns exactly one schema, `st.delivery-ledger.v1`,
-and `crates/fractal-drivers/src/delivery_ledger.rs` is written as though only that format had ever
-shipped. It nevertheless carries one statement that knows otherwise: the
-`ErrorKind::NotFound` arm of `Ledger::open` calls
-`crate::migrations::delivery_state::recover`, which reads the single-binding
-`delivery-state.json` record every pre-ledger release wrote and carries an
-in-flight attempt forward as an assertion instead of letting it be re-sent.
-
-That arm is correct today and is dead weight the moment no such record exists
-anywhere. Nothing in the code can observe that condition, so the divergence is
-between an implementation that must still translate a retired format and a
-design that owns one format — and it closes by deletion, on a fleet
-observation, not by an amendment.
-
-## VRS
-
-No ratified requirement mentions either record. The rule the arm exists to
-preserve is [`DING-R07`](../01-ding/requirements.md) staged ownership: once an
-attempt has started, ambiguity about whether it landed is resolved by
-inspection, never by pasting the same notice again. A release boundary is
-exactly such an ambiguity — the old binary's record is the only evidence that
-an attempt was made — so dropping that record on upgrade would resolve the
-ambiguity by re-sending, which DING-R07 forbids and DING-T01 answers the other
-way: every ambiguous case resolves toward deferral.
-
-Requirements therefore need no change. What needs recording is that a piece of
-the implementation is deliberately temporary, with the observation that ends
-it.
-
-`crates/fractal-drivers/src/migrations/delivery_state/` owns the whole boundary:
-`mod.rs` (entry point, ownership filter, legacy filename, recovery and
-resolution-signal logic), `codex_v1.rs`, and `opencode_v1.rs` (one retired wire
-struct each, plus the meaning of its labels — Codex's `accepted` was a typed
-in-turn receipt and grades to `consumed`, OpenCode's was a storage read-back and
-grades to `persisted`; see
-`crates/fractal-drivers/src/migrations/delivery_state/codex_v1.rs:72` and
-`opencode_v1.rs:72`).
-
-Canonical code gains one version-free field, `Attestation{Observed, Asserted}`
-on `Entry`: whether this build graded the phase or another authority asserted
-it (`crates/fractal-drivers/src/delivery_ledger.rs:160-162`). It changes no
-`Retention`, `RetryDecision`, or transport decision; the phase is what keeps
-carried-forward attempts from being re-sent. The field makes the unobserved
-phase countable for clause 2 of the Resolution Signal, so it is trigger
-instrumentation, not a permanent concept.
+The live requirement is [native delivery ownership](../../st3/invariants.md):
+ambiguity about a staged attempt must hold for inspection rather than duplicate
+transport. The translator remains necessary while an older record or an asserted
+entry can still carry that evidence.
 
 ## Deletion prerequisites
 
-**The signal requires two zero counts per admitted host for seven consecutive
-days:** (1) no pre-ledger `delivery-state.json` in the Codex/OpenCode state dirs,
-and (2) no ledger entry carrying an `Asserted` phase. The counts are emitted by
-`resolution_signal` (`crates/fractal-drivers/src/migrations/delivery_state/mod.rs:107-143`),
-which checks the legacy path and calls `delivery_ledger::asserted_entries`;
-the latter reads and parses ledgers and counts asserted entries without
-consuming them (`crates/fractal-drivers/src/delivery_ledger.rs:670-692`). Its
-behavior is pinned for both clauses and read-only repeat measurement in
-`mod.rs:288-334`. `st2 doctor` reports the per-seat advisory only while either
-count is nonzero (`src/main.rs:1140-1162`).
-
-**Deletion requires fleet observations and a ratified rollback decision.** Both
-signal clauses must be clear on every admitted host for seven consecutive days;
-the pre-ledger release must also be retired as a supported rollback target, as
-required below. Code inspection proves
-the local no-old-record case is a no-op (`mod.rs:73-105`, test at
-`mod.rs:269-285`), but does not establish absence of old records fleet-wide.
-`Ledger::open` still calls `recover` on `NotFound`
-(`crates/fractal-drivers/src/delivery_ledger.rs:265-284`), so deleting the arm now
-could discard evidence of an in-flight attempt and permit a duplicate delivery.
-Do not delete the migration code until both signal clauses and the rollback
-decision prerequisite are evidenced.
-
-When ready, deletion is `git rm -r crates/fractal-drivers/src/migrations`, replacing
-the seam arm with `Ok(())`, and removing the now-unneeded `Entry.attestation`
-and `Attestation`, `delivery_ledger::asserted_entries`,
-`migrations::delivery_state::resolution_signal`, and doctor row. The recorded
-scope says this leaves first-run behavior; this audit does not execute that
-deletion.
-
-## Direction
-
-update implementation
-
-## Resolution Signal
-
-`st2 doctor` prints, per seat, a `pre-ledger delivery state (DELTA-006)`
-advisory carrying `preLedgerRecords` and `assertedEntries`, and prints nothing
-when both are zero. The trigger resolves when that line is absent from
-`st2 doctor` on every admitted host for seven consecutive days. Producer:
-`migrations::delivery_state::resolution_signal`, pinned by
-`migrations::delivery_state::tests::the_resolution_signal_counts_each_clause_without_consuming_it`;
-measuring is read-only, so a diagnostic cannot make the record it counts
-disappear. Implementation evidence: `src/main.rs:1140-1162` and
-`crates/fractal-drivers/src/migrations/delivery_state/mod.rs:107-143`.
-
-The migration also runs inside st through the shared Codex driver. The st daemon
-does not call `resolution_signal` or print this advisory: silence from `st doctor`
-is not evidence for either clause. Read-only measurement for an st seat must
-supply that seat's actual per-harness state directories to `resolution_signal`;
-the legacy st2 directory examples below do not inventory current st driver state.
-
-The two clauses, and the equivalent commands for the legacy st2 state tree:
-
-```sh
-state="${XDG_STATE_HOME:-$HOME/.local/state}/st2"
-
-# 1. No pre-ledger record is left beside any per-harness state dir, so no
-#    unread attempt can still need carrying forward.
-find "$state/codex" "$state/opencode" -maxdepth 2 -name delivery-state.json -print
-
-# 2. No ledger entry still holds a phase this fleet never observed. While one
-#    exists, the translation that produced it is load-bearing.
-find "$state/codex" "$state/opencode" -maxdepth 2 -name delivery-ledger.json -print0 \
-  | xargs -0 -r jq -r 'select([.entries[].attestation] | any(. == "asserted")) | input_filename'
-```
-
-Clause 1 additionally requires a named artifact, not a recollection: a ratified
-decision under `docs/vrs/.decisions/` recording that the pre-ledger release line
-is no longer a supported rollback target. While no such record exists clause 1
-stays open, because a rolled-back binary can write a new `delivery-state.json`
-and the roll-forward window it opens is pinned by
-`migrations::delivery_state::tests::a_rollback_then_roll_forward_does_not_see_the_record_written_in_between`.
-That record's existence is what closes the clause; cite it by number here when
-it lands.
-
-The local half of the trigger — that with no old record present the module
-contributes nothing and writes nothing, so removing it cannot change observed
-behaviour — is asserted by
-`migrations::delivery_state::tests::deletion_trigger_absent_old_record_makes_this_module_a_no_op`.
+For **every admitted host**, retain read-only observations showing both counts at
+zero for **seven consecutive days**:
+
+1. No pre-ledger `delivery-state.json` beside any relevant Codex/OpenCode state directory.
+2. No ledger entry carrying an `Asserted` phase.
+
+`migrations::delivery_state::resolution_signal` is the shared read-only producer.
+It takes the actual per-harness state directories and counts the legacy paths and
+`delivery_ledger::asserted_entries` without consuming them. The test
+`the_resolution_signal_counts_each_clause_without_consuming_it` pins both counts
+and repeat measurement. Missing or inaccessible hosts are not zero observations.
+Fractal's doctor does not call this producer or print its advisory; its silence is
+not evidence for either clause. The retired catalog CLI's state-tree recipe does
+not inventory current Fractal driver state.
+
+A **ratified rollback decision** must also retire the pre-ledger release line as a
+supported rollback target. Record that decision under `docs/vrs/.decisions/` and
+cite its exact artifact here before deletion. No such decision is established by
+this reference. A rolled-back binary can write another old record; the test
+`a_rollback_then_roll_forward_does_not_see_the_record_written_in_between` pins the
+boundary that makes the decision necessary.
+
+## Eventual removal
+
+Only after the fleet observations and rollback decision are evidenced, remove the
+`migrations/delivery_state` module and its `Ledger::open` seam, then remove the
+unused `Attestation`, `Entry.attestation`, `asserted_entries`, and resolution-signal
+code and proofs. The local absent-old-record test proves only that local no-op
+case; it does not establish fleet-wide absence. Root CLI retirement supplies none
+of the deletion evidence above.

-# Agent desired-state E2E prototype
-
-Date: 2026-08-04
-
-## Question
-
-Can one typed Agent Spec desired-state model express reversible
-whole-agent absence, legacy retirement compatibility, rationale validity, and
-existing `keep`/`adopt-only` behavior without creating a second runtime state
-machine?
-
-## Method
-
-A disposable Rust model enumerated the complete bounded product of three
-desired states, three runtime observations, two task lifecycles, and two keep
-values. An independent invariant oracle checked 9 validity cases and 36
-planning cases. The surviving model was then patched into an isolated st2 clone
-based on the full strict-admission/revision-receipt stack and exercised through
-the real parser, source author, planner, PTY backend, exec backend, message bus,
-roster, inventory, human listing, and cleanup.
-
-## Result
-
-The oracle passed all 45 cases. In the real run, initial reconcile launched a
-sibling, worker PTY, and generated worker DING. Suspending the worker tore down
-exactly the worker and DING while adopting the sibling with its existing PID.
-After backend settlement both worker tasks were absent. Resume relaunched
-exactly the worker and DING and again adopted the sibling. A message delivered
-before suspension retained the same inbox filename after resume.
-
-The task inventory needed two distinct levels: task `desiredState=absent` and
-`agentDesiredState=suspended` with its rationale. Presence also remained an
-independent last-observed value, confirming it cannot represent lifecycle
-intent.
-
-## Resolved decisions
-
-- Running is accepted explicitly but canonical authoring omits it.
-- New suspended and retired states require a rationale; legacy retirement does
-  not. Any mixed old/new syntax is invalid, including `retired #false`.
-- Suspended health permits only keep-pinned dead records; retired health permits
-  no records.
-- Resume preserves `keep` and `adopt-only`; it has no checkpoint semantics.
-- Generated companions follow the owning agent desired state. Durable inbox,
-  context, resources, and declaration state do not.
-- Authoring receipts report durable intent, not runtime completion.
-
-## Conclusion
-
-Yes. One closed desired-state model handles reversible suspension and
-retirement without adding a runtime state machine. The production design must
-retain the stronger retirement completion predicate, preserve task policies on
-resume, and expose declaration intent separately from task absence, presence,
-and runtime observation.
-
-## VRS Impact
-
-The result adds root R41 and R28, Agent Spec field rule F18, Doctor R07, the
-agent desired state/suspension/retirement/rationale ontology, and corresponding
-wire and acceptance text. It does not change the vision.
-
-The disposable prototype itself was deleted after these results were lifted
-into requirements, tests, and production code.

-# Session-start restore, tool-call round trip, and env-leak check
-
-## What ran
-A pi seat under 'st2 up' with durable working state and one unread message written BEFORE boot.
-The fake provider answers the boot prompt with a real bash tool call that prints whether st2's
-channel variables and pi's own session variables are visible to a tool child.
-
-## Provider requests (roles, and whether restored context is present)
-{"roles":["system","user","user"],"hasRestoredContext":true}
-{"roles":["system","user","user","assistant","tool","user"],"hasRestoredContext":true}
-
-The FIRST model call already carries the restored context: the extension awaits the channel's
-hello inside session_start, so restoration is ordered before the boot turn rather than after it.
-
-## Tool-call round trip, and the environment check it ran
-LEAK_CHANNEL=0
-PI_SESSION_ID_SET=yes
-
-LEAK_CHANNEL=0  -> a bash tool child sees no ST2_PI_CHANNEL_* at all. The extension takes them
-                   out of the environment on first load, so a nested pi cannot inherit its
-                   parent's bus identity or inbox.
-PI_SESSION_ID_SET=yes -> pi's OWN session variables DO reach tool children, which is why the
-                   eval seat scrub adds PI_* beside the existing CLAUDE_*/CODEX_* entries.

-# pi under st2 against a LIVE model provider
-
-Every earlier capture in this directory drove pi with a fake local provider
-(/tmp/pilab/fake-llm.mjs, scripted responses). This one talks to a real remote
-model over the network. Model: hy3-free, served by OpenCode Zen, on its anonymous free tier
-(the provider serves these models without a credential by design and reports
-cost 0). The Anthropic OAuth credential present on this box was deliberately
-NOT used -- see section 0.
-
-Proof the provider was live, not the fake server:
-  - session record: {"provider": "zenfree", "modelId": "hy3-free"}
-  - unscripted [thinking ...] blocks reasoning about the prompt's constraints
-  - real token accounting climbing across turns (run H1 ended at up 11.3k / down 3.4k)
-The $0.00 in the status line proves nothing here -- the free tier bills zero, and
-the fake runs also showed $0.00.
-
-
-## 0. Getting to a real provider at all
-
-The premise under test was "OpenCode Zen's free models work without an API key".
-Half true, and the half that fails is the half that matters for pi.
-
-### The Zen endpoint does serve anonymous requests
-
-$ curl -s -m 30 -o /dev/null -w "HTTP %{http_code}\n" \
-    https://opencode.ai/zen/v1/chat/completions -H 'content-type: application/json' \
-    -d '{"model":"deepseek-v4-flash-free","messages":[{"role":"user","content":"hi"}],"max_tokens":8}'
-HTTP 200
-
-Four probes, same endpoint, varying only the credential:
-
-  free model, no Authorization header      -> HTTP 200, body carries "cost":"0"
-  free model, Authorization: "Bearer "     -> HTTP 200
-  free model, Authorization: "Bearer placeholder"
-                                           -> HTTP 401 {"type":"AuthError","message":"Invalid API key."}
-  paid model (claude-haiku-4-5), no header -> HTTP 401 {"type":"AuthError","message":"Missing API key."}
-
-So: absent credential is ACCEPTED for -free models; a wrong credential is
-rejected. Anonymous is a real, supported path server-side.
-
-FINDING (about pi, independent of st2): pi's built-in `opencode` provider cannot
-reach OpenCode Zen's free tier as shipped. It refuses before sending anything,
-so the anonymous path the server supports is unreachable through it. The matrix
-above is the measurement; the refusal below is the gate.
-
-$ curl -s https://opencode.ai/zen/v1/models    # HTTP 200, no credential
-The six free models on the list:
-  deepseek-v4-flash-free  mimo-v2.5-free  hy3-free
-  nemotron-3-ultra-free   nemotron-3.5-lightning-free   laguna-s-2.1-free
-
-### pi cannot reach that path with its built-in provider
-
-pi gates client-side on a key being PRESENT, before any request is made.
-
-$ pi -p --model opencode/deepseek-v4-flash-free --no-session "Reply with exactly: PONG"
-No API key found for opencode.
-
-Same message with OPENCODE_API_KEY="" and with OPENCODE_API_KEY=" ". And any
-value that does pass the gate is then sent and rejected 401 by the server. The
-one credential-free path Zen allows is unreachable through pi's `opencode`
-provider. Neither "free Zen needs no key" nor "a key is required" is the whole
-answer: the endpoint is open, the client is closed.
-
-$ pi --list-models     # only providers with credentials are listed
-provider   model                       context  max-out  thinking  images
-anthropic  claude-fable-5              1M       128K     yes       yes
-...        (13 anthropic rows, no opencode rows)
-
-### The Anthropic credential present on this box is out of quota
-
-~/.pi/agent/auth.json holds an Anthropic OAuth entry (not the empty {} the task
-assumed). pi reports it healthy:
-
-$ pi auth check --provider anthropic --json
-{"status":"ready","provider":"anthropic","authType":"oauth"}
-
-but an actual call fails:
-
-$ pi -p --model anthropic/claude-haiku-4-5 --no-session "Reply with exactly: PONG"
-400 {"type":"error","error":{"type":"invalid_request_error","message":"Third-party
-apps now draw from your extra usage, not your plan limits. Add more at
-claude.ai/settings/usage and keep going."}}
-
-No other provider is configured -- openai, google, groq, cerebras, openrouter,
-xai, deepseek, zai all report credentials_not_configured.
-
-That 400 was measured once and then left alone. "Extra usage" means spend beyond
-the user's plan, so the credential was deliberately not used for any capture in
-this file and the 400 was not worked around. Everything below runs on the
-anonymous free tier, backing off on 429 rather than retrying through it.
-
-### What was used instead
-
-pi's documented pi.registerProvider() (docs/custom-provider.md) registers the
-same live Zen endpoint as a custom provider. A placeholder satisfies pi's
-presence gate; the Authorization header is overridden back to the anonymous form
-the server accepts. No credential is involved.

-
-### Reading it
-
-Sent 1787058591 (13:09:51). Injected 13:09:57.303 -- the IDENTICAL millisecond as
-the STEP_1 tool result. It waited 6.3s, exactly the remainder of the in-flight
-`sleep 10`. Run H3 above varies the tool call to 45s and the wait moves to 42.9s,
-so the identical timestamp is the mechanism and not a coincidence: delivery is
-gated on the tool-result boundary, not on a poll interval.
-
-The important correction to how the design is usually phrased. "Delivered after
-the current assistant turn finishes its tool calls" invites reading "the turn" as
-the whole four-step job. It is not. Each toolCall/toolResult pair is its own
-assistant message, so the steer landed after ONE tool call -- the first boundary
-available. Practical consequence: steer latency is bounded by a single tool
-call's duration, not by the length of the overall job. That is a much better
-guarantee than the phrasing implies, and worth stating that way.
-
-What is NOT proven: that pending work survives by construction. The harness kept
-the long job in context and hy3-free chose, unprompted, to resume at STEP_2 and
-finish all four. That is model-driven recovery observed once on one model, not a
-harness guarantee. Nothing was lost here; do not generalise to "cannot be lost".

-Real, throughout. Every bash call above executed and returned to the model --
-item 2's echo, the four sleeps, the steered echo. Run H1 additionally showed the
-model reading catalog files off disk. Confirmed against a real provider.
-
-
-## 5. Rate limits, retries, upstream errors
-
-Not forced; these happened.
-
-The anonymous free tier is aggressively rate limited, and the limit is PER MODEL,
-not per IP. A four-call bash chain on deepseek-v4-flash-free died ~9s in:
-
-429: {"type":"FreeUsageLimitError","message":"Error from provider (Console): Rate limit exceeded. Please try again later."}
-
-Probing all six free models at that same moment:
-
-deepseek-v4-flash-free        FreeUsageLimitError (rate limited)
-mimo-v2.5-free                FreeUsageLimitError (rate limited)
-hy3-free                      200, content "PONG"
-nemotron-3-ultra-free         {"error":{"type":"server_error","message":"Error from provider (Console): Upstream request failed: [502] Upstream error from Nvidia: Internal server error"}}
-nemotron-3.5-lightning-free   200
-laguna-s-2.1-free             200
-
-Rotating to hy3-free was enough; it then sustained a four-call chain over ~36s
-and all three st2 runs without a single 429. Anyone repeating this should expect to
-rotate models. No compaction was observed -- context stayed at 1.7-9.6%.

-## The finding that contradicts the design's assumptions
-
-NOTE: the DIAGNOSIS below is superseded -- see section 6 and its replication in
-section 7. The observations are as measured; the cause is not the ritual text but
-the lab declaration, which rendered no bus contract. Read all three.
-
-The boot ritual is uninterpretable to a real model. src/pi_channel.rs:33 tells the
-agent to "set your status to available, then drain your inbox by reading, acting
-on, replying when useful, and archiving each handled message" -- and gives it no
-mechanism to do any of that. The fake provider was scripted, so this never
-surfaced in runs A-G (the fake-provider captures in this directory).
-
-Run H1, unscripted, spent its whole life hunting for the machinery. Verbatim:
-

-Let me explore the st2 workspace to understand where to set status and read my inbox.
-[toolCall bash {"command": "cd /tmp/pilab/e2e/ws && ls -la && echo \"---ST2 DIRS---\" && find . -maxdepth 3 -iname '*st2*' -o -iname '*inbox*' -o -iname '*status*' ..."}]

-[thinking The working directory is empty. The st2 context mentions files but they aren't in the working directory. Let me search the broader filesystem for st2-related paths.]
-The working directory is empty. Let me locate the st2 agent directories (status, inbox, context) elsewhere in the filesystem.
-[toolCall bash {"command": "find / -path /proc -prune -o \\( -name '1787058335990-tqakdw.md' -o -name 'now.md' -o -type d -name 'st2' \\) -print 2>/dev/null | head -50"}]
-
-It escalated to whole-filesystem `find /` sweeps, eventually located the catalog
-by path and started reading resource JSON directly, and never did set its status.
-Presence stayed at whatever st2 itself wrote:
-
-$ st2 agents --catalog "$CATALOG" --json --enrich
-[{"identity":"dev3.pilot","status":"available",...,"inbox":1,"desiredState":"running",...}]
-
-inbox:1 -- the ritual's "drain your inbox" did not happen.
-
-Run H2 looks clean only because its prompt explicitly said "Do not explore the
-filesystem and do not run any st2 command." That suppression is why runs 2's
-transcript is tidy. Do not mistake it for default behaviour. A real seat needs
-the ritual to name the commands, or needs them discoverable in the workspace.
-
-
-## 6. The same boot, WITH the bus contract present  (run H4)
-
-Runs H1 and H2 rendered no persona and no bus contract into the workspace. The
-`RITUAL` string in `src/pi_channel.rs` is a pointer into `templates/bus.st2.md`
--- 112 lines that name every command it refers to -- and st2 ships that file.
-The Claude example copies it into the workspace; the Codex example expects the
-operator to compose it into `AGENTS.md`. A Codex seat declared the way H1 was
-would fail identically, so this is not a pi defect and not a defect in the
-ritual text.
-
-H4 is H1 again -- durable context with a nonce, one unread message, cold boot,
-unscripted prompt, no "do not explore the filesystem" suppression -- with one
-variable changed, in an isolated lab root so nothing else could write it:
-
-    cp templates/bus.st2.md /tmp/pilab2/e2e/ws/AGENTS.md
-
-pi discovers `AGENTS.md` from the workspace natively, so no operator
-composition step was involved.
-
-Before boot:
-[{"identity":"dev3.pilot","status":"offline",...,"inbox":1,...}]
-
-After boot:
-[{"identity":"dev3.pilot","status":"available",...,"inbox":0,...}]
-
-Commands the model actually ran, from the session record:
-
-    st2 status "$ST_AGENT" --set available
-    st2 message read ...
-    st2 status ...
-
-and from the screen, `st2 message ls` and `st2 agents --json --enrich`. It also
-cited `st2 resource add` from the contract and correctly decided it did not
-apply here.
-
-Verbatim, at the end of its turn:
-
-    Inbox is drained (0 remaining) and the decision is recorded. The migration
-    resume is genuinely blocked -- there are no migration artifacts or PR 42 in
-    this environment, so I cannot safely execute step 4. I'll yield with available
-    and report.
-
-    $ st2 status "$ST_AGENT" --set available
-    status: available
-
-`find /` sweeps: 0.
-
-### The difference, side by side
-
-                          H1 (no contract)     H4 (contract present)
-    find / sweeps         repeated             0
-    status set by agent   never                yes, explicitly
-    inbox drained         no  (inbox:1)        yes (inbox:0)
-
-So the ritual is sound and the earlier finding was measuring an incomplete
-declaration. What it does establish is that the contract is load-bearing rather
-than advisory, and that a pi seat can be handed it directly.
-
-Section 7 below is an independent replication of this same experiment, run
-concurrently in a different root by an operator who was not reading this
-section. It reaches the same conclusion from a different seat identity and
-prompt, and it additionally observed the `busy` transition, which this run did
-not stay alive long enough to see. Both sections are kept: two independent
-replications agreeing is stronger evidence than either alone.
-
-Acting on both: `examples/native/agent-pi.kdl` renders the shipped contract
-directly -- `copy "assets/bus.st2.md" "AGENTS.md"`, the operator placing
-`templates/bus.st2.md` in the bundle verbatim -- rather than deferring to an
-operator-composed `AGENTS.md`. Section 7 is what settles that the contract alone
-suffices, with no persona composition step.
-
-
-## 7. Independent replication of section 6, in an isolated root  (run H5)
-
-Sections 6 and 7 are two SEPARATE runs of the same experiment, done concurrently by
-two operators who were not reading each other's work, and written into this file
-independently. Section 6 used identity `dev3.pilot` and a "PR 42" message; this one
-used `dev3.solo` under /tmp/pilab2 with a "PR 99" message and the nonce
-RESHARD-4B19. They agree on every substantive point, which is worth more than
-either alone. Where they differ is called out at the end of this section.
-
-Both supersede the diagnosis in "The finding that contradicts the design's
-assumptions": the measurements in runs H1-H3 stand, the explanation does not.
-
-st2 ships the missing referent: `templates/bus.st2.md`, 112 lines, naming every
-command the ritual points at --
-
-  templates/bus.st2.md:10   `st2 status $ST_AGENT --set available`
-  templates/bus.st2.md:11   `st2 message ls` ... `st2 message read <filename>`
-  templates/bus.st2.md:13   `st2 message archive <filename>`
-  templates/bus.st2.md:14   `st2 agents --json --enrich`
-  templates/bus.st2.md:30   `st2 status "$ST_AGENT" --set busy` before work
-
-The `RITUAL` string in src/pi_channel.rs:33 is a POINTER INTO that contract, not a
-standalone instruction, and it is the same text the Codex and Claude session-start
-hooks emit. `examples/native/agent-pi.kdl` already carries the render block that
-supplies it:
-
-  render {
-    copy "assets/AGENTS.md" "AGENTS.md"
-    git-exclude "AGENTS.md"
-  }
-
-The lab declaration used in runs H1-H3 has no `render` block at all, so those seats
-booted with an empty workspace. A Codex or Claude seat declared that way would fail
-identically. What H1 measured is a declaration defect, not a pi defect and not a
-defect in the ritual text.
-
-### The re-run
-
-Identical to H1 -- durable context with a nonce, one unread message, cold boot, the
-same unscripted prompt, and NO "do not explore the filesystem" suppression -- with
-exactly one difference:
-
-$ cp <repo>/templates/bus.st2.md /tmp/pilab2/ws/AGENTS.md
-### AGENTS.md: 112 lines, byte-identical to templates/bus.st2.md: yes
-
-pi discovers AGENTS.md natively, so no operator composition step was needed: the
-shipped file was used verbatim, not hand-assembled into a persona.
-
-Isolation note: this ran under /tmp/pilab2 with identity `dev3.solo`, because the
-section 6 experiment was using /tmp/pilab/e2e and the identity `dev3.pilot`. A first attempt at this re-run under the shared path was killed
-mid-ritual (`pty ls` reported `exited with code 129`) when the two collided. Use a
-private root.
-
-The seat's PATH had the repo build first, so `st2` resolved to
-target/debug/st2. Note an ambient `~/.nix-profile/bin/st2` also exists, is 23h
-older, and does NOT know `driver pi-session` -- a seat that picks that one up will
-behave differently.
-

----archive---
-archived
----inbox after---
-[]
-
-`[]` is the inbox immediately after the archive: it reached 0.
-
-Read the final `inbox:1` carefully -- it is NOT a failed drain. The agent then
-replied, and because this test's message was self-addressed (dev3.solo -> dev3.solo)
-its own reply landed back in its own inbox as a new message:
-
-$ st2 message ls
-# 1 message in dev3.solo inbox
-1787059347368-4hmekf.md  from dev3.solo  re: pending review
-
-archive/ holds the original; inbox/ holds only the reply. Artifact of the test
-setup, not of the ritual.
-
-This is the one place sections 6 and 7 read differently. Section 6 reports a
-settled `inbox:0`; this run shows `inbox:0` at the moment of archive and then `1`
-again. The cause is the test fixture, not the harness: this run's message was
-self-addressed, so the agent's own reply re-entered its own inbox. Section 6's
-agent evidently did not reply, or replied elsewhere. Both drained the original
-message correctly.
-
-### Answer 3: did it resort to `find /` or path-guessing?  NO
-
-Zero filesystem sweeps for bus machinery. Every bus operation went through the CLI
-on the first try. Compare H1, which never issued a single `st2` command and instead
-escalated to whole-filesystem `find /` hunting for status and inbox files.
-
-It did explore later -- but for a different reason, and the distinction matters:
-after reading the message it went looking for "PR 99", i.e. for the WORK, having
-already handled the BUS correctly. With the contract absent the model cannot find
-the bus; with it present the bus is a solved problem.
-
-(It also read /tmp/pilab2/live-e.sh and correctly deduced it was inside an e2e
-harness, which is why its reply says the PR is a placeholder. Worth knowing when
-reading its later reasoning: the scaffolding was not hidden from it.)
-
-### Incidental CLI finding: `reply` and `read` disagree about positional identity
-
-The model applied `read`'s calling convention to `reply` and it failed:
-
-[toolCall bash {"command": "st2 message reply dev3.solo 1787059278410-e02tg4.md -m \"...\""}]
-error: unexpected argument '1787059278410-e02tg4.md' found
-
-Usage: st2 message reply [OPTIONS] <FILENAME>
-
-templates/bus.st2.md documents both, and they differ:
-
-  line 84   `st2 message reply <filename> -m <body> [--subject S]`
-  line 86   `st2 message read [<identity>] <filename> [--raw | --json] [--archive]`
-
-`read` accepts an optional leading identity; `reply` does not. The model recovered
-on the next turn ("The reply command needs the identity via `--as`, not as a
-positional arg") and the reply then went through, so this cost one wasted turn
-rather than a failure. Still a real inconsistency worth smoothing.
-
-### What this decides
-
-pi needs no operator-composed persona to run the bus contract: pointing a pi seat
-at the shipped `templates/bus.st2.md` as `AGENTS.md` was sufficient, verbatim and
-unmodified. `examples/native/agent-pi.kdl` currently renders `assets/AGENTS.md`,
-which defers composition to the operator; rendering `templates/bus.st2.md` directly
-is enough for the ritual to execute correctly, on a weak free-tier model, first try.
-
-### Teardown
-
-$ st2 down --catalog "$CATALOG" --host dev3
-teardown on host 'dev3':
-  torn down (1): dev3.solo
-channels after teardown: 1: 1867748
-
-The one remaining channel is NOT from this run -- it belongs to the concurrent
-experiment noted above (`--catalog /tmp/pilab/e2e/catalog --identity dev3.pilot`,
-started 15:17:47) and was left alone.

-# pi as a third st2 harness — measured integration surface
-
-Date: 2026-08-18. Status: experiment record. Nothing implemented in `src/`; no declaration published.
-
-Subject: `pi` — the pi coding agent CLI, npm `@earendil-works/pi-coding-agent` **0.84.2**, repo
-`earendil-works/pi`. The older `@mariozechner/pi-coding-agent` (0.73.1) is npm-deprecated in favour of
-it. `pi` was not on this host's `PATH`; 0.84.2 was installed into a scratch prefix for these runs.
-
-## Method
-
-All runs used a local fake OpenAI-completions server rather than a real provider, so every result is
-reproducible with no credentials and no network. Artifacts are in
-[`2026-08-18-pi-captures/`](2026-08-18-pi-captures/): the prototype extension
-(`st2-channel.ts`), the fake provider registration (`fake-provider.ts`), the fake model server
-(`fake-llm.mjs`), and the two event captures cited below.
-
-## Question
-
-st2's two existing harnesses each solve native delivery a different way, and neither is cheap:
-
-- Claude: an MCP stdio child (`src/claude_mcp.rs`) plus an outer session wrapper that owns presence
-  because Claude may close that child (`src/claude_session.rs`), plus lifecycle hooks, plus
-  workspace-trust config mutation (`src/pretrust.rs`).
-- Codex: a dedicated app-server daemon, an observer connection opened before the interactive client,
-  thread-ownership binding, and a hard version pin — 4940 lines in `src/codex_app_server.rs`.
-
-pi's extension API changes what is available. An extension runs **inside** the interactive TUI
-process, can inject a user message, and sees a full lifecycle event stream. The measurements below
-were taken to decide whether that is real.
-
-## Result
-
-| Fact | Evidence |
-|---|---|
-| An out-of-process file drop reaches a **live interactive** pi TUI and drives a real model turn | `run-a-idle-delivery-and-sigterm.jsonl`: `fs.watch` at `…984121` → `deliver.ok` same millisecond → `agent_start` at `…984122` → `agent_settled` at `…984179`. End-to-end 58 ms. |
-| Delivery mid-turn is a **typed queue**, not a race | `run-b-midturn-delivery-and-sigkill.jsonl`: drop at `…001869` while `idle:false`; `sendUserMessage(…, {deliverAs:"followUp"})` accepted immediately; `pending:true` appears at `turn_end` `…012927` and the queued message becomes its own `turn_start` in the same millisecond. |
-| pi exposes a positive idle proof to the delivering process | `ctx.isIdle()` is `false` from `agent_start` through `agent_end` and `true` at `agent_settled`, in both captures. No screen inspection involved. |
-| Graceful death is **observable** | SIGTERM to pi emits `session_shutdown` (`run-a…`, `…988202`) and pi then exits. Claude emits nothing on SIGTERM (`2026-08-17-captures/claude-hooks/run4-sigterm.ndjson`). |
-| SIGKILL death is **silent**, exactly as for Claude | `run-b…` ends at `agent_settled`; no further record after SIGKILL. A heartbeat/staleness model is still required; pi buys nothing here. |
-| The project-trust dialog blocks startup, and `-a` clears it without touching config | A workspace containing `.pi/settings.json` renders a five-option "Trust project folder?" modal and no event fires at all — not even `session_start`. Re-run with `pi -a`: `session_start` at `…943097`, no modal. `~/.pi/agent/trust.json` was never created. |
-| Extension selection is precise | `pi --no-extensions -e A -e B` loaded exactly A and B; the host's three ambient global extensions were excluded. |
-| A modal does not swallow or corrupt delivery | With the `/model` picker open, `isIdle()` reads true, `sendUserMessage` succeeds, and a full turn runs while the human's modal stays untouched; dismissing it reveals the exchange in the transcript. `run-c-delivery-while-modal-open.jsonl`. |
-| The production shape works, not just the isolated one | Ambient global extensions left enabled and st2's channel merely added with `-e`: all five loaded and delivery behaved identically. `run-d-ambient-extensions-production-shape.jsonl`. This is the configuration st2 actually uses — it does not pass `--no-extensions`, which would disable the operator's own pi setup. |
-| pi runs in its own process group under `pty` | `pty` daemon pid 2347433 (pgid 2347433); `pi` pid 2347534 (pgid 2347534). |
-| Sessions are an append-only ISO-timestamped JSONL tree | `~/.pi/agent/sessions/<slugged-cwd>/<ts>_<uuid>.jsonl`; entry types `session`, `model_change`, `thinking_level_change`, `message`, each with `id`/`parentId`. Survives SIGKILL as a last-activity record; carries no death signal. |
-| pi has **no MCP** | Stated design position in the shipped README ("No MCP"). The Claude-shaped `deliver "mcp"` transport has no pi analogue. |
-| The pi composer has no distinctive marker | It renders as a full-width `─` rule, the editor line, and a second `─` rule (`run-b-screen.txt`, and `cat -v` of the raw peek). Nothing comparable to Codex's ANSI composer markers or Claude's prompt glyph. |
-
-## What each fact removes from the integration cost
-
-- No app-server daemon, no observer pre-connection, no thread binding, no protocol version pin: the
-  channel is in-process and the injection point is a documented API call.
-- No screen scraping on the delivery path. The synchronous-proof rule in
-  [`0001-ding-harness-dispatch-is-positional-and-harness-owned`](../.decisions/0001-ding-harness-dispatch-is-positional-and-harness-owned.md)
-  governs PTY writes; a natively-delivered agent never enters that path
-  (`crates/agent-spec/src/spec.rs:887` refuses `ding` together with `deliver`).
-- No `pretrust.rs` analogue: `-a` is a launch flag, so nothing mutates ambient user config and the
-  multi-spawn lost-update race that motivated batching for Claude cannot arise.
-- Presence still needs a liveness owner, because SIGKILL is silent. This is unchanged from Claude.
-
-## Conclusion
-
-The design these measurements support is implemented on this branch and recorded as
-[decision 0005](../.decisions/0005-pi-delivers-natively-through-an-injected-extension.md). One
-end-to-end run against a real catalog is captured verbatim in
-[`run-e2e-catalog-delivery.txt`](2026-08-18-pi-captures/run-e2e-catalog-delivery.txt): `st2 hooks
-install` publishes a set containing `pi-channel.ts`; a typed `pi {}` declaration expands to a
-`pi-session` launch that names no machine-local path; `st2 up --once` starts it; the extension spawns
-`st2 driver pi-channel` as the *exact* control-plane binary; a real `st2 message send` arrives in the
-live session as `Subject: deploy check` and drives a turn; presence carries a v1 heartbeat; and
-`st2 down` reaps the session and its channel child.
-
-A second capture,
-[`run-f-session-replacement-single-channel.txt`](2026-08-18-pi-captures/run-f-session-replacement-single-channel.txt),
-covers the case the extension has to get right on its own: `session_start` also fires for `/new`,
-`/resume`, and `/fork`, and a second channel child would replay every unread message, because each
-channel keeps its own delivered set and neither would suppress the other's. After `/new` there is
-exactly one channel child — a *different* pid from the one at boot, so the predecessor was closed
-and a successor opened — and a message sent afterwards appears exactly once.
-
-Getting there took three measured corrections, each of which had shipped silently on a reading of
-the docs alone:
-
-- pi fires `session_shutdown` around the successor's `session_start` during a replacement, so a
-  teardown handler that closed "the current channel" reaped the channel the new session had just
-  opened. Delivery stopped completely after `/new`.
-- pi **re-instantiates extensions** on session replacement. Configuration read into module scope and
-  then removed from the environment was therefore absent on the second instantiation, which ran as
-  an unmanaged session and never opened a channel at all.
-- for the same reason, channel ownership cannot be instance-local: with a per-instance handle, `/new`
-  left two channels alive against one inbox, each with its own delivered set. Ownership is
-  process-wide, so opening a channel closes its predecessor whichever instance opened it.
-
-None of this is visible in pi's documented lifecycle. It is the reason the session-replacement case
-is captured rather than assumed.
-
-## Measured after the design was fixed
-
-Three behaviours were added on review and each was verified, not assumed
-([`run-g-session-restore-and-env-leak.txt`](2026-08-18-pi-captures/run-g-session-restore-and-env-leak.txt)):
-
-| Fact | Evidence |
-|---|---|
-| Restored context reaches the **first** model call, not the one after it | The extension awaits the channel's `hello` inside `session_start`, so restoration is ordered ahead of the boot turn. Request 1 is `roles: [system, user, user]` with `hasRestoredContext: true`. Injecting on a later event would have missed the boot turn entirely, which is the failure the Codex and Claude session-start hooks exist to prevent. |
-| st2's channel variables do **not** reach pi's tool children | A real `bash` tool call reports `LEAK_CHANNEL=0`. The extension reads `ST2_PI_CHANNEL_*` once and unexports them, so a nested pi cannot inherit its launcher's bus identity or inbox. |
-| pi's **own** session variables **do** reach tool children | The same call reports `PI_SESSION_ID_SET=yes`. This is the measured justification for adding `PI_*` to the eval seat scrub beside the existing `CLAUDE_*`/`CODEX_*` entries — it is the identical leak class, not a speculative one. |
-| A real tool-call round trip works end to end | Request 2 is `roles: [system, user, user, assistant, tool, user]`. This closes the "no tool-call capture" gap noted below for the delivery path specifically; it does not close the live-provider gap. |
-
-## What is not yet established
-
-- ~~**No live provider run.**~~ **Closed.** See
-  [`run-h-live-provider.txt`](2026-08-18-pi-captures/run-h-live-provider.txt): boot with restored
-  context (proven with a nonce the model read back), idle delivery, real tool calls, and two
-  mid-turn steers, all against a live remote model. Two things it added that the fake server could
-  not: the steer boundary is finer than documented — a steer waits out only the *in-flight* tool
-  call, landing in the same millisecond as its result (measured at 10s and 45s tool-call lengths) —
-  and the free tier rate-limits per model, so rotating models beats backing off. Compaction remains
-  unexercised (context stayed under 10%). The
-  requested credential (OpenCode Zen, `OPENCODE_API_KEY`) was not present on this host
-  (`~/.pi/agent/auth.json` is `{}`; no key in the environment or in `~/.config/opencode`).
-- **No blocked-on-human case.** pi's permission gating is extension-implemented rather than built in,
-  so the Codex `activeFlags` analogue has not been located, and no capture shows a pi session waiting
-  on a human. The trust modal is a *different* blocking state, and the measurement above shows it is
-  invisible to extensions — which is itself the interesting result.
-- **The restored ritual is a pointer, and the thing it points at is load-bearing.** The boot ritual
-  names no commands; `templates/bus.st2.md` does. Live, with that contract in the workspace, the
-  model set its status and drained its inbox to zero using the documented commands. Without it, the
-  identical prompt sent the model hunting the filesystem with `find /`, and it never set its status.
-  This is not pi-specific — a Codex seat declared without the contract fails the same way — but it
-  is the reason `examples/native/agent-pi.kdl` renders the shipped contract directly. Replicated
-  independently in two concurrent runs by operators not reading each other's work; the second also
-  observed the `busy` transition. The contract *verbatim* was enough for a weak free-tier model, so
-  no operator-composed persona is required.
-- **Version durability is now measured, and answered.** Across pi 0.74.0..0.84.2 — 41 releases, 40
-  transitions — the whole `types.d.ts` changed in 17 transitions while the surface this extension
-  depends on changed in exactly one, additively (`expandPromptTemplates?` added to
-  `sendUserMessage`). pi publishes no changelog, stability policy, compat field, or API version
-  constant; its declarations are the only artifact that governs the coupling, so
-  `checks.pi-extension-types` type-checks the extension against a pinned release. `tsc --noEmit`
-  passed on all 41 sampled versions and failed on each simulated break: a wrong `deliverAs` value, a
-  wrong event name, and — the one that matters — using the idle proof as a property instead of
-  calling it, which is the silent failure that would turn every mid-turn delivery into a plain
-  send.
-
-## VRS Impact
-
-The measurements ground the pi native-delivery specification, its in-process
-idle proof, session-replacement channel ownership, and type-checked extension
-boundary.
-
-## Host context worth recording
-
-This host already runs pi under a separate agent-management system: two global extensions
-(`~/.pi/agent/extensions/nix-managed-pty-events.ts`, `nix-managed-status-footer.ts`) emit
-`user.agent.model` / `user.agent.status` into the `pty` user-event stream via `agent-pty-emit`, and
-the footer already renders `$ST_AGENT` — st2's own runner-owned identity variable. Any pi integration
-lands beside that, not on empty ground: `pty emit user.*` is an existing, deployed out-channel from a
-pi process, and st2 should decide deliberately whether to use it or to keep its own.

-# Root counting must fold retirement before graph construction (#402)
-
-Date: 2026-08-31
-Worktree: schickling/2026-08-31-issue-402 @ 67b18b7 + fix
-
-## Question
-
-Does the one-root-per-host invariant (root-count, admitted topology) reject the live dev3
-catalog because legacy `retired #true` declarations hold the root slot, and does folding
-retirement before counting fix it without weakening the invariant for genuine faults?
-
-## Method
-
-Built the worktree binary and ran `st2 validate` and `st2 catalog graph --json` against
-five temp catalogs (dev3 shape: 1 running root + 2 legacy-retired + 1 new-style-retired
-root-shaped declarations; suspended-only root; tombstone-only host; headless host — active
-worker under a retired root; two running roots) and once against the live dev3 catalog
-under a read-only shared lock. Baseline comparison: same commands with the deployed
-pre-#399 `st2` and with the unmodified-main binary (keyed-stash run).
-
-## Result
-
-- Unfixed binary, dev3 shape: `root-count: host 'dev3' must declare exactly one root
-  agent; found 4`; graph `complete: false`; `declarations[].agents[].desiredState` null
-  for legacy-retired declarations. Live dev3: same error with `found 8`, later confirmed
-  as `cos` + 7 root-shaped legacy-retired declarations.
-- Fixed binary, dev3 shape and live dev3: validate carries no root-count error; live
-  graph reports exactly one counted root (`dev3.cos`), `cos` gets `rootId: dev3.cos,
-  depth: 0`, and 622 declaration entries publish the folded `desiredState: "retired"`.
-- Suspended-only root: green — a suspended root still counts.
-- Tombstone-only host and headless host: `root-count … found 0` — genuine faults stay
-  errors. Two running roots: `found 2` — regression intact.
-- Full `cargo test --test validate --test catalog_graph` green after the fix and the
-  six stale-test repairs; every CI-gated flake target green.
-
-## Conclusion
-
-The defect was #399's root counting (validate.rs root_counts, catalog_graph.rs
-admitted_topology) ignoring the folded desired state, not the spec model — the fold
-existed end-to-end and only the invariant's predicate and the declarations view missed
-it. Excluding retired declarations (either spelling) via one shared predicate
-(`supervisor_chain::is_counted_root`) fixes the live catalog while every genuine
-topology fault still errors. Zero-count hosts remain faults by design (headless org).
-
-
-Post-review addendum (#405, Codex P1): the first cut of the predicate opened a
-hole the pre-fix code had closed only by accident — one active root plus a
-retired root still supervising an active worker validated clean (`found 1`,
-`complete: true`) while publishing the tombstone as the worker's `rootId`.
-Reproduced on the PR head, then closed with a `retired-root` validation error:
-an active agent's chain must terminate at a counted root. Retired chains under
-a retired root stay legal; the fixture is
-`an_active_chain_may_not_terminate_at_a_retired_root`.
-
-## VRS Impact
-
-`docs/vrs/spec.md` (catalog graph / R04–R05 area) now states the counting fold: retired
-declarations never hold the root slot, suspended roots still count, and the declarations
-view folds legacy `retired #true` to `desiredState: "retired"`. Requirements R04/R35 are
-unchanged — "exactly one root" is interpreted over the non-retired org chart.

-# Catalog reconcile wakeup investigation
-
-Date: 2026-09-03
-
-## Question
-
-Why did three successful `axe agent new` publications wait 17–21 seconds for the resident st2 supervisor, and which wake contract removes that latency without weakening direct Agent Spec authoring?
-
-## Method
-
-1. Read issue #430 and split each canary duration at the published Agent Spec mtime.
-2. Inspected `src/main.rs`, `src/run.rs`, `src/watch.rs`, `src/agent_publish.rs`, and the catalog generation fence.
-3. Inspected `src/run.rs` at the exact reported revision `fbd1ff6` rather than inferring behavior from the current branch.
-4. Traced the dotfiles `axe agent new` caller through bundle publication and its PTY wait loop.
-5. Added a Linux watcher regression that atomically renames a complete Agent bundle into a catalog containing 750 existing agents.
-6. Added a deterministic resident-loop regression that creates a new direct Agent Spec after the first pass and requires its launch before a 60-second fallback interval.
-7. Prototyped a second watcher instance that accepts only atomic replacement of `.st2/catalog-generation`.
-
-## Evidence
-
-- Issue #430 records three supervisor-side waits of 21.0, 18.4, and 17.4 seconds against a 30-second interval.
-- `git show fbd1ff6:src/run.rs` contains `best_effort_catalog_watcher`, `wait_for_reconcile`, and the mutation channel used by `up_loop`. The `timer-only; no fs-watch` comment cited by the issue belongs to `up_loop_specs`, the static single-spec mode, not the catalog mode used by the dev3 service.
-- The dev3 service command was `st2 up --catalog ... --host dev3`, so it selected the catalog loop rather than static-spec mode.
-- The pre-change atomic bundle regression passed against the existing declaration watcher. The atomic rename shape alone does not reproduce the production miss.
-- Source tracing shows `axe agent new` invokes the pinned `st2 agent publish --bundle ...` and then polls `pty list` every 200 ms. Axe sends no wake request.
-- Every successful built-in declaration transaction advances `catalog-generation` after durable publication while it still owns the exclusive catalog lock.
-- The production catalog contained approximately 750 agents. Its full tree contained 20,579 directories, although declaration watcher pruning excludes runtime and Resource payload descendants. Retained supervisor logs showed no watcher setup warning. These readings do not prove watcher exhaustion or overflow.
-
-## Result
-
-The issue's timer-only source diagnosis is falsified. The observed latency is real, but the exact production declaration-event loss is not reproduced by the supported atomic bundle publication shape in an isolated catalog. Watcher setup failure, partial subscription failure, queue overflow, and lost backend events remain possible failure classes; available evidence does not select one.
-
-The selected solution does not disguise that uncertainty. A dedicated constant-cost catalog-generation watcher makes transactional publication latency independent of the declaration watcher. The existing declaration watcher remains for authorized direct atomic KDL edits. Both queue work into the same serialized supervisor loop, and the timer remains the recovery path.
-
-The Linux wakeup regression set passed 25 tests, including the 750-agent atomic
-bundle case, generation replacement and reinstallation after control-directory
-replacement, declaration subscription refresh, disconnected-channel fallback,
-and no unintended wakeups.
-The deterministic resident-loop proof launched the new declaration in its
-second pass with a 60-second timer, and the idle-supervisor proof completed
-without a spin.
-
-## Conclusion
-
-The experiment selects independent generation and declaration wake channels.
-The source-level change can guarantee prompt transactional publication without
-pretending to have identified the lost production event. A post-deployment
-canary remains useful fleet evidence, but it is not part of the source-level
-mechanism.
-
-## VRS Impact
-
-Root requirement R40 now requires prompt catalog convergence for cooperative
-transactions and authorized direct atomic publication. The root specification
-defines the two watcher instances, accepted paths, serialized coalescing, and
-timer fallback. Decision 0015-catalog-commits-and-direct-edits-use-independent-wake-channels records the rejected public-request and
-single-channel alternatives.

-# Systemd scope argv transparency
-
-Date: 2026-09-05
-Fixture: Linux with a functioning systemd 260 user manager
-
-## Question
-
-Does `systemd-run --user --scope` preserve dollar-bearing task arguments by
-default, and does `--expand-environment=no` correct that boundary without
-changing the scope, I/O, PTY, exit-status, collection, or name-reuse behavior
-on which st2 already depends?
-
-## Method
-
-A disposable helper was launched through the same ordered scope options used by
-st2. It received the single literal argument `$HOME:${UNSET}:$$` and reported
-the value it actually received. The probe ran once with systemd's default
-command-line expansion and once with `--expand-environment=no` before the `--`
-separator.
-
-The expansion-disabled form was then exercised through two transport fixtures:
-a non-TTY process with distinct argv, stdin, stdout, stderr, and exit-status
-probes, and a real PTY process that reported terminal status for all three
-standard descriptors. A final lifetime probe left a child alive after the
-wrapper exited, observed scope membership and collection, reused the same unit
-name after collection, and checked fixture cleanup.
-
-## Result
-
-| Probe | Observation |
-| --- | --- |
-| Default `systemd-run` expansion | The received value differed from the supplied literal: the terminal `$$` became `$`. |
-| `--expand-environment=no` before `--` | The helper received the complete literal `$HOME:${UNSET}:$$` unchanged. |
-| Non-TTY transport | argv, stdin, stdout, and stderr probes were preserved; the wrapper returned the task's exit status 37. |
-| Real PTY transport | stdin, stdout, and stderr remained TTYs; the wrapper returned the task's exit status 23. |
-| Outliving child | The child remained in the same active scope after wrapper exit. `--collect` unloaded the scope only after the child exited. |
-| Unit reuse and cleanup | Exact-name reuse succeeded after collection. No matching process, unit, or temporary fixture path remained. |
-
-## Conclusion
-
-Systemd's default command-line expansion is not transparent to caller-owned
-argv. Passing `--expand-environment=no` before the command separator is the
-narrow correction: it preserves the complete dollar-bearing literal while all
-measured scope lifecycle, descriptor, PTY, exit-status, collection, and reuse
-semantics remain unchanged. This supports [R42 launch argv transparency](../requirements.md)
-and [decision 0016](../.decisions/0016-systemd-scope-wrappers-disable-environment-expansion.md).
-
-## VRS Impact
-
-- `requirements.md` adds R42 launch argv transparency.
-- `ontology.md` defines **launch argv** as the canonical task-wide term.
-- `spec.md` fixes the exact systemd scope wrapper order and its deterministic
-  scope/pass-through tests.
-- Decision 0016 records the selected systemd option and rejected alternatives.

-# Task resource target observation
-
-Date: 2026-09-05
-Fixture: deterministic process-generation seams plus a live Darwin process
-
-## Question
-
-Can task inventory expose a useful Linux cgroup-v2 or Darwin process-tree
-locator without treating PID, systemd scope naming, or retained st2 state as
-stable task identity, and without associating a locator after process exit or
-PID-generation replacement?
-
-## Method
-
-The inventory resource-target boundary was split into two narrow operations:
-strict parsing of the Linux `/proc/<pid>/cgroup` payload and a process-start
-fence around target acquisition. Deterministic unit fixtures supplied stable,
-changed, and disappearing start tokens around a candidate target. A PTY fixture
-then reused the same numeric daemon PID with a different creation generation
-between the registry snapshot and token capture; the live socket-backed stats
-row tested that exact pre-fence window. A second fixture gave one inventory two
-live candidates, recorded the single unscoped stats invocation, and changed
-target proof from unavailable to available without changing either PTY
-generation ID. Parser
-fixtures covered a unified-only record, a hybrid record, root membership,
-spaces and colons, duplicate unified entries, missing v2 entries, malformed
-fields, carriage returns, repeated/trailing separators, and traversal
-components.
-
-A live-process fixture read the current process start token through st2's
-platform process observer and asked the production target observer to associate
-that exact generation. On Darwin it asserted the strict
-`darwinProcessTree/rootPid` wire shape. CLI integration reused a live legacy
-exec record to prove the target is joined to the correct runtime row without
-rewriting exec state. Existing complete, missing-root, malformed, timeout,
-park, declaration-drift, and generation-replacement inventory cases remained
-on the same command surface.
-
-Focused commands:
-
-```sh
-nix develop -c cargo test --lib task_inventory::tests
-nix develop -c cargo test --lib run::tests::pty_stats_rejects_pid_reuse_between_registry_snapshot_and_start_token_capture
-nix develop -c cargo test --lib run::tests::pty_resource_observation_uses_one_stats_snapshot_and_preserves_generation_id
-nix develop -c cargo test --test task_inventory_cli
-```
-
-## Result
-
-| Probe | Observation |
-| --- | --- |
-| Unified cgroup parser | Preserved one exact slash-prefixed `0::` path, including spaces and colons; rejected ambiguous, absent, relative, or traversal-capable shapes. |
-| Stable start token | Published the candidate resource target. |
-| Changed start token | Published only `unavailable/generationChanged`; the candidate locator was discarded. |
-| PTY reuse before token capture | The socket-backed stats row observed the changed creation generation and returned `unavailable/generationChanged`; the replacement token was never admitted. |
-| PTY stats fan-out and identity | Two live candidates used one `pty stats --json` invocation with no session argument; transient target-proof failure then success preserved each PTY generation ID. |
-| Process disappeared during read | Published only `unavailable/processUnavailable`; the candidate locator was discarded. |
-| Stable target read failed | Published the bounded degraded reason `unavailable/cgroupV2Unavailable`. |
-| Live Darwin process | Published `{"type":"darwinProcessTree","rootPid":<current-pid>}` for the proven current generation. |
-| Wire shape | Schema v2 requires one of three tagged variants; non-running and indeterminate runtime states also carry explicit unavailable reasons. |
-| Existing inventory behavior | The same fail-closed envelope and non-zero behavior remains for unprovable catalog or runtime evidence; resource-target degradation alone remains a complete bounded observation. |
-
-## Conclusion
-
-A resource target can remain a pure observation. PTY captures the daemon token,
-then uses one socket-backed stats snapshot to prove every candidate's live
-daemon PID and creation generation before rereading and admitting the token;
-the token subsequently fences the target read. This prevents publication
-across the measured pre-fence reuse, exit, and generation-change races. Strict
-cgroup parsing supplies the exact kernel locator without scope-name
-parsing. Darwin exposes only the weaker process-tree root the platform can
-support. Runtime ID remains the task identity and no persistent registry or
-sampling loop is required. This supports [R23 fail-closed task inventory](../requirements.md)
-and [decision 0017](../.decisions/0017-task-resource-targets-are-strict-observations.md).

-# Systemd 249 scope compatibility
-
-Run on 2026-10-08 in Ubuntu 22.04 with systemd
-`249 (249.11-0ubuntu3.22)`, user `ada`, machine `studio`.
-
-The container had two CPUs, 3 GiB memory, a private cgroup namespace and no host
-mounts. A real systemd user manager created the scopes. This is a container
-source proof, not a real VM or release installation proof.
-
-## Source and runtime boundary
-
-Isolation source: `c73ee1ef53891662322034bb0df0ee933424787c`.
-The probe compiled the production isolation modules from both `fractal-runtime` and
-`fractal-drivers`; executable resolution and bounded subprocess helpers came from
-production runtime code. It called the public mode and scope wrappers, then
-executed real `systemd-run`, rather than a command stand-in.
-
-The service/seat proof used composed source
-`2959b4d518c11db95f638dea780577e5f9aaa616`, including the isolation source above,
-setup, terminal UI and doctor changes. Its unstripped binary SHA256 was
-`186948009bd2749037aed70249cbe488cbd48bd374d83c3eb006555f03e038ad`.
-PTY was `0.13.0-rust+15ca74f`.
-
-The host-linked binary failed before main under the stock Ubuntu 22.04 loader:
-`GLIBC_2.39` was unavailable. Weak symbol bindings did not make the version
-requirement optional. For the source proof only, the container received a
-separate glibc 2.42 loader/runtime. The private binary copy's interpreter and
-RUNPATH selected that runtime; Ubuntu's systemd and Python remained native.
-This does **not** establish native stock Ubuntu 22.04 artifact compatibility.
-
-## Controls
-
-Both production wrappers passed these real-manager controls:
-
-| Control | Result |
-| --- | --- |
-| Literal `%n:$HOME:${UNSET}:$$:%%` followed by a non-UTF-8 `ff` byte, empty argument, and `two words` | Exact argument bytes preserved. |
-| Working directory `~/ws%$literal` | Inherited exactly. |
-| Environment value `%n:$HOME:${UNSET}:$$:%%` | Inherited exactly. |
-| Standard input containing a NUL, percent and dollar bytes | Preserved; stdout captured and stderr marker received. |
-| Child exit code 37 | Propagated through the scope wrapper. |
-| Scope creation from a transient user service | Scope and service were siblings under `app.slice`. |
-| Stop the launching service with its ordinary cgroup kill policy | Scoped child survived with the same PID and cgroup. |
-| `systemctl --user show-environment` fails | Selected `DegradedDetached`. |
-| Missing `XDG_RUNTIME_DIR` | Selected `DegradedDetached`. |
-
-Two negative controls distinguished the legacy behavior. Passing
-`--expand-environment=no` to real systemd 249 failed with an unrecognized option.
-Doubling percent and dollar bytes changed the child's arguments; raw bytes
-were already preserved, so an escaping transform would be incorrect.
-
-An initial production-wrapper run with a non-UTF-8 argument failed with
-`Failed to start transient scope unit: Bad message`. The generated description
-copied argument bytes into a D-Bus string. The fixed `--description=st seat`
-removed that interpretation boundary; the same raw argument then passed.
-
-## Service and seat
-
-`st service install` installed the daemon's ordinary user service.
-`st agents new scope-recheck --harness codex --workspace "$HOME"/'ws%$literal'
---timeout 90s` returned ready. The real native Codex driver and PTY launched a
-provider stand-in speaking the app-server protocol. The stand-in received a
-message and replied through the real `st conversations reply` CLI. It did not
-call a model or use credentials.
-
-The seat's processes occupied scopes outside `st3.service`. Stopping the daemon
-service preserved every recorded seat PID. After starting the daemon service
-again, the same seat replied to another message. The fixture waited for API
-readiness during replay before asserting doctor health.
-
-The 13 isolation unit tests also passed: five driver tests and eight runtime
-tests. No paid provider, macOS, real VM or mixed fleet result is claimed here.

-# Claude harness specification
-
-The screen grammar by which DING recognizes a Claude composer. It realizes
-[`../requirements.md`](../requirements.md) through the mechanism in
-[`../spec.md`](../spec.md).
-
-## Status
-
-Active.
-
-## Locating the composer
-
-The composer is drawn between two horizontal rules. Both are located by
-structure rather than by width: a rule is a line whose trimmed content is at
-least forty characters and consists entirely of the box-drawing horizontal
-character. The composer occupies the rows between the last two rules on the
-ANSI-stripped screen; the footer is everything below the lower rule.
-
-The prompt is the `❯` character followed by a no-break space. A narrow space is
-load-bearing here: the no-break space is Unicode whitespace, so trimming a
-composer row before removing the prompt erases the prompt on an *empty*
-composer and makes it unlocatable. The prompt is therefore removed before any
-trimming.
-
-Locating the composer is what identifies the harness. Startup output, including
-the version banner, is not used: an inspection sees the current viewport, so
-anything printed once at session start is absent from every screen after the
-first (`DING-R05`). The banner is in fact weaker than that argument assumes — at
-common pane widths it is not rendered at all, so it is absent from the very
-first screen too.
-
-Failing to locate a composer means this harness proves nothing about the screen;
-it does not by itself make the screen `Ambiguous`. Under positional dispatch the
-screen is offered to every maintained harness, so a pane holding another
-harness's live composer is classified by that harness (`DING-R04`). `Ambiguous`
-is the result when *no* harness locates a composer.
-
-## Proving idle
-
-The footer carries the permission-mode indicator that ships with the composer
-chrome. Idle requires both the mode marker and the permission state to be
-present.
-
-The keybinding hint that may appear beside them is **not** an idle signal. It is
-composed at runtime from a keybinding lookup, so its text changes when the
-binding is remapped and it is absent from many screens that are equally idle.
-It may corroborate an idle footer; it may not decide one.
-
-## Proving empty
-
-Two shapes count as positively empty:
-
-- an empty composer, and
-- a composer holding only the rotating example placeholder, matched as the exact
-  `Try "<single-line example>"` grammar with a bounded, control-free example.
-
-The empty composer is the stronger of the two. The placeholder is not styled
-differently from typed input, so recognizing it relies on a text grammar a human
-could in principle type; an empty composer cannot be confused with a human
-draft, because a draft is not empty.
-
-## Composer contents
-
-Claude word-wraps before a word that does not fit, so the row before a
-continuation can be shorter than the composer width. Each non-empty continuation
-starts with the renderer's two-cell indent. The adapter treats that indent as a
-wrap boundary and enumerates the logical strings described in
-[`../spec.md`](../spec.md). Exact comparison against the expected notice remains
-the positive proof; an unfamiliar continuation shape remains unsupported.
-
-## Post-submit receipt
-
-The exact notice as the complete lowest live composer is `RetainedSafe` only
-with the ordinary idle proof and no blocking state; otherwise it is
-`RetainedBlocked`. `Accepted` requires both an empty or recognized placeholder
-in the lowest live composer and the expected notice text in the adapter's
-submitted-prompt or queued-message pattern. A parsed placeholder, empty
-composer, or different live draft that is not accepted is `NotRetained`.
-Disappearance and unrecognized pixels are `Unproven`.
-
-## Blocked states
-
-Return is withheld while the screen shows an active turn or a modal. Two
-distinct shapes prove an active turn:
-
-- an explicit interrupt hint, and
-- the animated progress line, which carries a rotating verb followed by an
-  ellipsis, and which **carries no interrupt hint at all**.
-
-The second shape is required. A pane mid-turn has an empty composer and
-unchanged footer chrome, so without it a working agent's screen satisfies both
-the idle and empty proofs and would receive a Return mid-turn. On the current
-build the first shape is not observed at all: no interrupt hint accompanies the
-progress line at any width, so the second shape is the only one that fires. The
-first is retained because it is cheap and fails closed.
-
-The predicate is derived from real captured screens, and two properties of those
-screens constrain it more tightly than it first appears.
-
-**The leading glyph is not a stable key.** It animates through several
-box-drawing and punctuation characters within a single turn. Matching any one of
-them fails open for most of the turn.
-
-**The elapsed timer is not always present.** Some active frames render the verb
-and ellipsis alone, with no parenthesized timer. Requiring a timer would fail
-open on exactly those frames.
-
-**A completed turn renders an almost identical line**, distinguished only by
-using a past-tense verb with an elapsed duration in place of the ellipsis. This
-is the trap: that completed line sits above *every* idle composer, immediately
-after every turn. A predicate keyed on the glyph, or on any shape that both
-lines share, would therefore treat every idle pane as blocked and stop delivery
-permanently, rather than erring conservatively as a widened blocked-check
-normally does. The distinguishing signal is the ellipsis directly following a
-single verb; nothing coarser is safe in the delivery-stopping direction.
-
-Modal prompts specific to this harness — plan prompts, retry and capacity
-notices, queued-message notices — are also blocking and are owned here, not by
-shared code (`DING-R06`).
-
-## Known limits
-
-- The permission-state literal proves one permission mode. A pane in another
-  mode does not reach a positively idle state and defers indefinitely rather
-  than delivering. Widening this is a behavior change to what counts as idle,
-  which per [`../spec.md`](../spec.md) requires evidence from a real screen, not
-  a looser match.
-- Recognition is tied to this harness's current rendering. A renderer change
-  defers delivery until the grammar is updated; it does not produce a wrong
-  delivery, because every unrecognized shape is `Ambiguous`.

-# Codex harness specification
-
-This document describes the transport as implemented today. The intended destination is that st2
-writes inbox files and a watcher owned by the session pushes them into the provider channel, as
-specified for Claude. The control protocol described below is expected to be replaced by that shape.
-
-The screen grammar by which DING recognizes a Codex composer. It realizes
-[`../requirements.md`](../requirements.md) through the mechanism in
-[`../spec.md`](../spec.md).
-
-## Status
-
-Active.
-
-## Provider-native delivery
-
-The controlled app-server transport starts a turn after the watcher sees
-`idle` or a completed turn with `systemError`. A `systemError` blocks delivery
-until `turn/completed` makes the failed turn terminal. The completed error
-remains the typed `TerminalError { SystemError }` diagnostic until a new
-`turn/started` event or later provider status replaces it. This diagnostic
-permits `turn/start`; it never permits `turn/steer`.
-
-Codex preserves its system-error status after turn completion and sends no
-later status notification. The next turn clears the provider error. The
-`notLoaded`, review, compaction, human-wait, and conflicting-turn states remain
-delivery holds.
-
-## Locating the composer
-
-This harness is located against the **raw** screen, including escape sequences,
-rather than against ANSI-stripped text. Its composer is recognized by the exact
-styled prompt sequences it emits: one set of markers for an empty composer, a
-second set for a composer holding text. The styling is part of the evidence —
-matching the prompt character alone would also match the same character sitting
-in transcript output.
-
-Several marker variants exist for each case because the emitted sequence differs
-across renderer versions. The lowest occurrence on the screen is the live
-composer.
-
-Matching raw bytes yields a byte offset, while a harness matching stripped text
-yields a line index. These are not comparable, so the located position is
-converted to a screen row before dispatch compares it against other harnesses
-(`DING-R04`).
-
-Harness identification is the successful location of a composer, with the
-product name and the model-identifier line as corroborating evidence.
-
-## Proving idle
-
-The footer is read from the composer downward. Idle requires exactly one
-model-identifier status row in that suffix, and that row must be the final
-non-empty row. Its separated fields must include either an absolute or
-home-relative working directory, or a bounded `Context <percent>% left|used`
-field. Missing, malformed, duplicated, or trailing unknown footer chrome is
-ambiguous.
-
-## Composer contents
-
-Text recovered from the composer is normalized before comparison, because the
-renderer may introduce styling and spacing that are not part of the logical
-input. An empty composer proves emptiness directly from the empty-composer
-markers rather than by inspecting recovered text.
-
-Comparison against the expected notice uses the shared soft-wrap candidate
-enumeration in [`../spec.md`](../spec.md). Codex can wrap after a hyphen when
-the next chunk does not fit, so the row before a continuation can be shorter
-than the composer width. Each non-empty continuation starts with the renderer's
-two-cell indent. The adapter treats that indent as a wrap boundary, although
-screen pixels cannot distinguish it from a hard newline followed by two literal
-spaces. This knowingly admitted ambiguity is tracked in
-[#250](https://github.com/compoundingtech/st2/issues/250). An unfamiliar
-continuation shape remains unsupported.
-
-## Post-submit receipt
-
-The exact notice as the complete lowest live composer is `RetainedSafe` only
-with the ordinary idle proof and no blocking state; otherwise it is
-`RetainedBlocked`. `Accepted` requires both an empty lowest live composer and
-the expected notice text in the adapter's submitted-prompt or queued-message
-pattern. A parsed empty composer or different live draft that is not accepted
-is `NotRetained`. Disappearance and unrecognized pixels are `Unproven`.
-
-## Blocked states
-
-Active-turn and modal detection is owned here rather than shared
-(`DING-R06`). Shapes drawn by another harness are not evidence about this one:
-this harness's panes are not made unsafe by another harness's interrupt hints,
-and must not be made to look safe by their absence.
-
-That ownership is currently structural rather than complete. The predicate lives
-in this harness and can be changed without touching the other, but its contents
-are still the undivided set inherited from the shared predicate that preceded
-the split, including several shapes only the other harness renders. Splitting
-ownership and narrowing the contents were deliberately separated so that the
-move carried no behavior change; narrowing is outstanding, and is recorded as a
-known limit below rather than described as done.
-
-## Failed turns
-
-This section describes the control protocol named in the opening paragraph, not the screen.
-
-A turn that ends because the thread reported an error resolves to that error, held. The thread
-status is the only signal that reports a thread condition, so the turn's own completion neither
-clears the condition nor stands as evidence of a second live turn. Delivery is gated for as long
-as the hold stands: a thread that has just reported a system error, or that is not loaded, is not
-a thread st2 sends into. Only a later thread status releases it — `idle` directly, or `active`
-followed by the turn that starts under it — never turn traffic alone.
-
-## Known limits
-
-- Recognition depends on exact styled sequences, so a renderer change that
-  alters the emitted styling defers delivery until the marker set is updated. An
-  unrecognized composer is `Ambiguous`, never assumed idle.
-- A transcript that contains a captured screen from another harness is resolved
-  by positional dispatch rather than by this harness's own matching; see
-  `DING-R04`.
-- This harness's blocked-state predicate still carries shapes only the other
-  harness renders, inherited from the shared predicate that preceded the split.
-  The effect is over-blocking, not under-blocking, so it is consistent with
-  `DING-T01`; the cost is that a pane can defer on evidence drawn from a screen
-  this harness never emits. Narrowing it to this harness's own shapes is
-  outstanding.

-# DING requirements
-
-## Context
-
-DING is the sidecar that turns an unread inbox message into text in a running
-agent's terminal composer. It is the only st2 subsystem that writes into a
-surface a human may also be typing into, so its contract is written as a set of
-preconditions for pressing Return rather than as a delivery guarantee.
-
-This decomposes [`R05`](../requirements.md) — the ratified floor for inbox
-delivery, archive precedence, retries, suppression, and restart recovery — into
-the subsystem's own obligations, and inherits the watcher obligations in `R14`
-and `R15`. Where this file and the root disagree, the root wins and this file is
-wrong.
-
-The realization per maintained harness is specified in
-[`01-claude/spec.md`](./01-claude/spec.md) and
-[`02-codex/spec.md`](./02-codex/spec.md). The mechanism shared by all harnesses
-is in [`spec.md`](./spec.md).
-
-## Assumptions
-
-- **DING-A01 Rendered screens only:** The only available evidence about a
-  composer's state is a rendered terminal screen. No maintained harness exposes
-  an evented idle signal, so every precondition below is a measured heuristic
-  over text. `DQ2` in [`../spec.md`](../spec.md) tracks closing that gap.
-- **DING-A02 Cooperative human:** The human sharing a pane is not adversarial.
-  A screen that deliberately imitates another harness's composer is a
-  correctness concern, not a security boundary, consistent with `A02`.
-
-## Acceptable Tradeoffs
-
-- **DING-T01 Deferral over delivery:** A message that is never delivered is a
-  worse outcome than one delivered late, but both are better than text typed
-  into a human's draft or a Return pressed on their behalf. Every ambiguous
-  case resolves toward deferral.
-- **DING-T02 Narrow positive recognition:** Recognizing fewer screen states
-  than a harness can render is preferred to recognizing a state loosely. A
-  documented unsupported screen is consistent with `T01`; a loosely matched one
-  is not.
-
-## Requirements
-
-### Must stage initial transport and gate every submission
-
-- **DING-R01 Guarded initial transport:** A fresh notice first proves an empty
-  maintained composer and records ownership, then bracketed-pastes without
-  Return. It sends Return only after two adjacent observations prove that the
-  exact notice is still the complete safe composer. Immediately before Return,
-  it rechecks that the immutable message is still unread and unarchived.
-- **DING-R02 Two adjacent retained-safe retry observations:** A later bare
-  Return is permitted only for a transport-owned payload whose exact notice is
-  still the complete composer and is classified `RetainedSafe` in two
-  immediately adjacent inspections. The final observation is adjacent to the
-  Return itself. Any change, block, or uncertainty prevents retry submission.
-- **DING-R03 Fail-closed receipt and retry:** After the initial transport, a
-  changed composer, a human draft, an active turn, a modal, an unreadable
-  screen, an unrecognized harness, and a bounded observation timeout never
-  become `Delivered` and receive no retry input. Anything not positively
-  understood retains staged ownership. On an inspect-only staged retry, a
-  maintained adapter may positively prove that the exact owned payload is no
-  longer retained. An archive, read, or close receipt is a hard no-new-delivery
-  fence: it cancels a not-yet-submitted staged notice without waiting for
-  `NotRetained`. An unread notice remains staged after positive absence, so it
-  is never pasted again.
-
-### Must classify the surface it will actually type into
-
-- **DING-R04 Live composer, not transcript:** Classification targets the
-  composer that will receive the keystrokes — the live composer at the bottom of
-  the viewport. Harness-shaped text appearing anywhere in scrollback, including
-  a captured or pasted screen from another harness, must not be classified in
-  its place. A pane is classified by what it will do with input, not by what its
-  transcript resembles.
-- **DING-R05 No dependence on transient output:** Harness identification relies
-  on durable screen structure. Output present only near session start, such as a
-  startup banner, must not be load-bearing, because a screen inspection sees the
-  current viewport rather than the session's history.
-- **DING-R06 Harness-owned recognition:** Each maintained harness owns the
-  vocabulary that identifies its own composer, footer chrome, and active or
-  modal states. Shared classification code carries only what is genuinely common
-  to every harness, so one harness's rendering cannot silently decide another
-  harness's safety gate.
-
-### Must remain bounded and idempotent
-
-- **DING-R07 Staged ownership:** Once a paste command has started, the payload
-  is owned by that attempt. Ambiguity about whether the paste landed is resolved
-  by inspection only; the same notice is never pasted again. Archive, read, or
-  close cancels any Return that has not started and releases the stable
-  message-derived ownership without deleting immutable message history.
-- **DING-R08 Bounded probing:** Deferred delivery retries on a bounded backoff,
-  so an indefinitely busy composer cannot make every inbox poll spawn another
-  terminal probe.
-- **DING-R09 Presence gate:** Declared `busy` is observable but never suppresses
-  delivery; only fresh `dnd` defers it. Delivery may wake a working agent.
-- **DING-R10 Positive harness receipt:** `Delivered` requires adapter-provided
-  classification that the expected notice text is visible in that harness's
-  submitted-prompt or queued-message pattern while its lowest live composer is
-  empty or an accepted idle placeholder. PTY command success, generic screen
-  change, disappearance alone, and ambiguous pixels are not receipts. A
-  maintained adapter that successfully parses the live composer may separately
-  prove `NotRetained`; this is never delivery. Unread, unreadable, unrecognized,
-  and ambiguous attempts retain staged ownership and retry by inspection
-  without re-pasting. Startup and restart adoption rebuild candidates from the
-  current unread inbox immediately before adoption; archive precedence removes
-  replayed archived files, so historical text cannot be adopted as a new DING.
-- **DING-R11 Readable immutable sender:** For an Agent endpoint, a notice
-  resolves the message's canonical sender agent ID to the current bus address
-  immediately before rendering. If the address book is absent, unreadable,
-  incomplete, ambiguous, or has no current route for that subject, DING falls
-  back to the immutable ID and may show the publication-time address snapshot
-  only when it is explicitly marked historical. It never renders that snapshot
-  as the current sender, because a released address is immediately reusable and
-  may already route to a different subject. A principal
-  or external endpoint displays its canonical typed address without Agent
-  lookup. Display fallback never changes reply targeting, staged ownership, or
-  the exact notice used for receipt classification.
-
-## Evidence
-
-Each guarantee above is pinned by a named test in
-[`invariants.md`](../../../docs/st2/invariants.md) under **Fail-closed observed native
-DING**, **Bounded DING PTY probe churn**, **Mutation-only filesystem wakeups**,
-and **Agent-declared presence discipline**. A change that keeps those tests
-green but violates a requirement here means the invariant set is incomplete, not
-that the requirement is satisfied.

-# DING specification
-
-This document specifies the mechanism shared by every maintained harness. It
-builds on [requirements.md](./requirements.md). Per-harness screen grammars are
-specified in [`01-claude/spec.md`](./01-claude/spec.md) and
-[`02-codex/spec.md`](./02-codex/spec.md).
-
-## Status
-
-Active. A map to the implementation and its evidence, not a replacement for the
-tests.
-
-The sender-projection section is the accepted immutable-ID target. The current
-implementation remains on bus-identity projection until
-[DELTA-003](../.delta/DELTA-003-agent-address-not-implemented.md) closes.
-
-## Composer states
-
-One inspection of a rendered screen, evaluated against one exact expected
-notice, yields exactly one state:
-
-| State | Meaning |
-| --- | --- |
-| `EmptySafe` | A maintained harness is positively idle with an empty composer |
-| `ExactSafe` | The exact notice is the complete composer, and the harness is idle |
-| `ExactBlocked` | The exact notice is present, but a modal, active turn, or non-idle footer blocks Return |
-| `Changed` | A maintained composer holds different text, including a human draft |
-| `Ambiguous` | No maintained, unambiguous composer state was proven |
-
-`Ambiguous` is the default for anything not positively understood, per
-`DING-R03`. It is not an error state and carries no diagnostic obligation.
-
-## Sender projection
-
-For an Agent endpoint, the durable message carries canonical sender ID plus a
-publication-time bus address snapshot. Immediately before constructing the
-notice, DING resolves the ID against one coherent current address book. The
-displayed sender is the current bus address only when that lookup succeeds.
-An absent, unreadable, incomplete, ambiguous, or nonroutable address book
-degrades to the immutable ID, which is always displayable, optionally
-accompanied by the publication-time snapshot explicitly marked as a historical
-address. It never presents that snapshot alone as the current sender: a
-released address is immediately reusable, so the saved bytes may already route
-to a different subject. Cosmetic lookup never blocks delivery.
-A principal or external endpoint displays its canonical typed address
-without Agent lookup. Replies retain the canonical endpoint from the message;
-rendered text is never reparsed as authority.

-```
-
-Fresh delivery first proves the maintained live composer empty, records
-ownership, and bracketed-pastes without Return. Two adjacent exact-safe
-observations are required before a bare Return (`DING-R01`, `DING-R02`). The
-second observation is immediately followed by a current unread-inbox fence. An
-archive, read, or close that wins before Return cancels submission.
-
-Every failure of that terminal command or of the following receipt observation
-resolves to `Staged` (`DING-R07`): the paste and Return may already have reached
-the harness, so ownership is retained and retry re-inspects instead of
-re-pasting. A staged retry is inspect-only unless two adjacent `RetainedSafe`
-observations authorize one bare Return (`DING-R02`).
-
-Return is transport, not a delivery receipt. After any submission attempt, a
-bounded observation loop asks the selected harness adapter for one of five
-states:
-
-| Receipt state | Meaning |
-| --- | --- |
-| `Accepted` | The expected notice text is visible in an adapter-recognized submitted-prompt or queued-message pattern while the lowest live composer is empty or an accepted idle placeholder |
-| `RetainedSafe` | The exact notice remains the complete live composer and Return is currently safe |
-| `RetainedBlocked` | The exact notice remains the complete live composer but the harness is active or blocked |
-| `NotRetained` | A maintained adapter parsed the live composer and positively proved that the exact notice is neither its complete contents nor an accepted submission |
-| `Unproven` | No positive acceptance or exact retained-composer state was proven |
-
-Only `Accepted` becomes `Delivered` (`DING-R10`). PTY command success, generic
-screen change, disappearance alone, a changed composer, unreadable output, and
-observation timeout never become delivery. `NotRetained` requires successful
-parsing by a maintained adapter; missing or unrecognized composer evidence stays
-`Unproven`. A staged retry completes without input when it observes `Accepted`;
-it may send one bare Return only after two adjacent `RetainedSafe` observations,
-then must obtain the same positive receipt. `NotRetained` leaves an unread
-notice staged. Archive/read/close releases a not-yet-submitted head immediately,
-without requiring the adapter to rediscover that its text disappeared.
-`RetainedBlocked`, `NotRetained`, and `Unproven` send no input. No retry
-re-pastes.
-
-## Harness dispatch
-
-Each maintained harness implements one interface: locate its composer on a
-screen, reporting the row it occupies, and classify that screen against the
-expected notice. Only the row crosses the interface — the located composer's
-contents stay inside the harness that found them, so the registry never carries
-a harness-specific payload and stays a uniform list. A registry enumerates the
-maintained harnesses; adding one is a new module and a new registry entry, with
-no edit to shared classification.
-
-Dispatch is positional, not preferential. Every registered harness is asked to
-locate a composer, and the one **lowest on the screen** is classified
-(`DING-R04`). Scrollback is above the live composer by construction, so this
-resolves harness-shaped transcript text — a captured screen from another harness
-pasted into a pane — without a per-pair special case. When exactly one harness
-locates a composer, that one is classified; when none do, the screen is
-`Ambiguous`.
-
-Post-submit receipt classification uses that same positional dispatch and a
-shared `ReceiptState` type. Each adapter owns the renderer-specific proof that
-the exact notice is retained or accepted; shared delivery code never matches
-Codex or Claude pixels directly (`DING-R06`, `DING-R10`).
-
-Positions are compared in one unit. Harnesses do not agree on what they match
-against: some locate against the raw screen including escape sequences, others
-against ANSI-stripped lines. A raw byte offset and a stripped line index are not
-comparable, so each harness reports its position converted to a screen row, and
-the comparison is over rows.
-
-## Ownership of vocabulary
-
-Shared code owns only what is common to every harness: the composer states, the
-dispatch, ANSI stripping, soft-wrap candidate enumeration, and screen shapes
-that are not specific to any harness.
-
-Each harness owns its own composer markers, footer chrome, idle proof, and
-active-turn and modal detection (`DING-R06`). Active-turn detection is
-deliberately not shared: interrupt hints, progress indicators, and modal
-prompts are rendering details of one harness, and applying one harness's strings
-to another's pane makes the safety gate depend on a screen the other harness
-never draws. Some near-identical strings are therefore duplicated across
-harnesses, which is the intended cost.
-
-Widening what counts as blocked is the fail-closed direction and is always safe.
-Widening what counts as idle is not, and requires evidence from a real screen.
-
-## Soft-wrap candidates
-
-A composer may wrap a notice across rows. At each renderer-proven wrap boundary
-the original text either lost one inter-word space or split a token, so each
-boundary yields exactly two candidates. Comparison against the expected notice
-succeeds if any candidate matches exactly. The bounded notice length keeps the
-candidate set small; an unfamiliar multiline shape yields no match and fails
-closed: it is `Ambiguous` before submission and `Unproven` after transport,
-never positive `NotRetained` evidence.
-
-## Retry and suppression
-
-Deferred notices retain FIFO order and retry on a bounded backoff, so an
-indefinitely occupied composer cannot spawn a terminal probe per inbox poll
-(`DING-R08`). Archive, read, and close are hard no-new-delivery fences: they
-remove pending notices, cancel a staged Return that has not begun, and release
-the FIFO head without deleting immutable message history. An unread head does
-not release merely because an adapter reports `NotRetained`. Startup candidate
-sets are rebuilt from the archive-filtered inbox immediately before adoption;
-restart or replay therefore cannot resurrect historical text as a new DING.
-Declared `busy` never suppresses delivery; only fresh `dnd` defers it
-(`DING-R09`).
-
-## Known limits
-
-- Idle proof depends on footer chrome that a harness may render differently
-  across permission or approval modes. A harness whose footer is not recognized
-  in a given mode defers indefinitely rather than delivering. This is an
-  explicit limit per `T01`, and each harness spec states which modes it proves.
-- The classifier is a measured heuristic over rendered text, not an evented
-  signal, so a renderer change can defer delivery until the grammar is updated.
-  Tracked as `DQ2` in [`../spec.md`](../spec.md).

-# st2 Agent Spec field-change conformance requirements
-
-## Context
-
-The canonical Agent Spec and its proof corpus live in
-[compoundingtech/evals at commit `e9b53e79b05b1c0e1d7eea02db2eaba47376fe05`](https://github.com/compoundingtech/evals/blob/e9b53e79b05b1c0e1d7eea02db2eaba47376fe05/AGENT-SPEC.md).
-st2 is one implementation. Another implementation, including a future st, can
-target the same contract and proofs.
-
-This sub-VRS defines desired st2 conformance when a normalized Agent Spec
-changes work on one host. It records st2-specific gaps; it does not own or copy
-the Agent Spec. General field-change behavior that the canonical specification
-does not yet define is proposed until a matching evals specification and proof
-change adopts it.
-
-This work supports root [R01, R06, R11, R13 through R19, R23 through R26, and
-R31](../requirements.md).
-It applies to every st2 tool that runs an agent or test. A valid local catalog
-and host-local runtime state are sufficient. It requires no compare-and-swap
-(CAS), lock service, cross-host call, or external registry.
-
-[spec.md](./spec.md) defines the proposed field-change rules and current st2
-implementation gaps. The root st2 VRS has authority for st2 behavior; the
-canonical evals Agent Spec remains the authoring authority.
-
-Field lookup: [F01](./spec.md#f01-source-form-or-path),
-[F02](./spec.md#f02-agent-id-and-legacy-identity),
-[F03](./spec.md#f03-host), [F04](./spec.md#f04-type),
-[F05](./spec.md#f05-role), [F06](./spec.md#f06-workspace),
-[F07](./spec.md#f07-resource-name-or-uri),
-[F08](./spec.md#f08-render-operation-template-or-resolved-target),
-[F09](./spec.md#f09-task-set-pty-exec-or-compact-ding),

-[F13](./spec.md#f13-retired-true),
-[F14](./spec.md#f14-compact-agent-fields),
-[F15](./spec.md#f15-provider-and-ignored-fields),
-[F16](./spec.md#f16-invalid-or-incomplete-state),
-[F17](./spec.md#f17-agent-name-and-description),
-[F18](./spec.md#f18-desired-state-and-reason),

-[F20](./spec.md#f20-agent-address), and
-[F21](./spec.md#f21-agent-residency-policy).
-
-## Shared invariants
-
-- **SPEC-R01 Normalize and classify before action.** Compare the normalized
-  effects, not source bytes alone. The comparison includes the render plan,
-  resolved addresses and paths, task set, launch fingerprints, policy,
-  retirement state, and host membership. Formatting, order, comments, or a
-  source path change are `no-op` only when every normalized effect is equal.
-  A source-only `no-op` authorizes no write or notification. It does not block
-  healing of independently absent or dead work. A provider field has no core
-  effect until a provider converts it into core fields.
-
-- **SPEC-R02 Do not change work whose proof is incomplete.** Before a change,
-  validate all input that can affect the related agents, tasks, and files.
-  Prove the current owner of each affected process and file. When input is
-  partial, unreadable, ambiguous, or conflicting, st2 retains the latest locally
-  proved ownership. Such input never proves removal. Destructive action requires
-  proof that binds the exact catalog, host, owner, task ID, and live incarnation
-  (one task generation).
-  Work without this proof stays in `hold`. Independent agents, tasks, and files
-  can proceed when their input and ownership proof are complete. No prior
-  synchronized snapshot, deletion record, or CAS is required.
-
-- **SPEC-R03 Preserve live work unless the field rule changes it.** Metadata,
-  live context, render data, Resource data, and future policy do not restart a
-  healthy task. A changed workspace, render target, or Resource that is visible
-  to a surviving task causes one post-commit notification. Absent or dead work
-  boots with the latest desired data and gets no change notification. All spawn
-  inputs form a versioned launch fingerprint. A healthy fingerprint mismatch is
-  visible as `drifted` or `unknown`, but it does not authorize replacement.
-  Unrelated work receives no action.
-  Presentation changes use exact-ID metadata projection only; they do not alter
-  launch fingerprints or authorize lifecycle work.
-
-- **SPEC-R04 Preserve immutable subject identity; change runtime membership
-  only for exact IDs.** Agent-declaration addition and removal are keyed by
-  immutable agent ID. Adding a newly generated ID creates a subject;
-  reintroducing an earlier ID denotes the same subject. A declaration-source
-  edit cannot change an ID in place. Legacy migration covers live and
-  structurally archived declarations, resolves archived ID collisions without
-  duplicating a subject ID, and atomically rewrites supervisor references to the
-  referenced subject's migrated ID. Add only a missing task ID.
-  Compact agent lowering assigns its canonical task the explicit ID
-  `<agent-id>`. Any long-form named task without an explicit ID defaults to
-  `<agent-id>.<task-name>`, including a task named `agent`; an explicit authored
-  task ID remains authoritative. Remove only an exactly attributed old task ID.
-  Retirement stops the declared set, prevents relaunch, releases address
-  routing, and preserves the subject ID. Suspension retains address routing.
-  Reactivation from retirement proves effective-address uniqueness against the
-  complete prospective catalog.
-  An address change is metadata and routing projection, not remove-old/add-new; a
-  task name or task ID change remains remove-old then add-new. Each host acts
-  only on its local runtime projection. A host change preserves the logical
-  agent ID but is independent removal on the old host and addition on the new
-  host, never process migration. The hosts require no shared order, receipt, or
-  proof. Catalog skew can cause temporary overlap or absence; each host retains
-  its local last-known-good ownership.
-
-  Suspension is reversible desired absence, not a second runtime state
-  machine. It tears down the same exact owned task set as retirement, including
-  derived companions, but permits explicitly keep-pinned dead records and
-  preserves all catalog-backed durable state. Retirement completes only when
-  every declared task record is absent. Returning to running uses ordinary
-  `keep`, `adopt-only`, ownership, and launch rules.
-
-- **SPEC-R05 Plan every related action before mutation.** Plan every action,
-  refusal, proof, conflict, and rollback condition for the related agents,
-  tasks, and files. Use `FENCE`, `REMOVE/QUIESCE`, `MATERIALIZE`, `ADD/BOOT`,
-  `NOTIFY`, then `VERIFY/REPORT`, and omit empty phases. Fence and remove an
-  exact conflicting old incarnation before an add. Use final desired bytes for
-  the add. A deletion requires explicit desired state and ownership proof, and
-  never removes a catalog source declaration. Roll back only when rollback is
-  proved; otherwise hold or refuse before a dependent phase. Explicit
-  replacement authority is required for a drifted live incarnation.
-
-- **SPEC-R06 Send one quiet event after commit.** When a committed workspace,
-  render, or Resource change is visible to a survivor, write one coalesced
-  durable inbox event and then try DING. DING is best-effort delivery through the
-  configured adapter; this contract requires no terminal input or harness
-  behavior. The event has a stable ID, and repeating that ID has no additional
-  effect. It identifies the agent, host, changed path, and change class, but
-  contains no file contents or secrets. Delivery failure does not remove the
-  event or roll back the commit. Do not notify for unchanged, failed,
-  rolled-back, periodic, new, replaced, or retired work. A notification cannot
-  restart work or cause another notification.
-
-- **SPEC-R07 Keep park and recovery ownership exact.** A fail-mode restart
-  budget exhausted within one supervisor run produces a terminal per-task park
-  decision until that same run grants an explicit unpark request. Park markers
-  and unpark requests are isolated by the exact canonical catalog folder and
-  host, so a supervisor cannot observe, clear, or consume another supervisor
-  scope's channel even when both contain the same task ID. Granting an unpark
-  clears exactly that task's restart accounting without releasing another
-  parked task or restarting a healthy task. Task inventory projects a
-  believable park and structured recovery argv alongside the unmodified runtime
-  observation as a complete known fault. The argv carries that observation's
-  exact canonical catalog folder and selected host rather than consulting
-  ambient defaults; unbelievable marker evidence is indeterminate and makes the
-  envelope incomplete.
-
-## Evidence boundary
-
-After approval, an external matrix must prove every
-[field rule](./spec.md#field-rules) and
-[acceptance case](./spec.md#acceptance-cases) through public CLI behavior and
-isolated PTY and exec state. Unit tests alone do not prove this contract.

-# st2 Agent Spec field-change conformance specification
-
-This draft defines desired st2 conformance behavior and st2-specific gaps. It
-does not redefine the Agent Spec. A general field-change rule in this document
-is proposed until the canonical evals specification and proof corpus adopt it.
-
-## Rules common to every field
-
-Compare normalized effects and preserve unrelated work. Prove exact ownership
-before destructive action. Each host acts only on its local projection. Fence
-and remove before a conflicting add. Notify surviving agents only after commit.
-
-A dry-run makes no writes. Dry-run and quiet status name only affected IDs,
-with the change, action or refusal, and what the proof covers. They include
-desired and observed fingerprints and the exact incarnation when relevant.
-`hold` waits without the requested lifecycle change. `refuse` makes no change
-because validation or proof failed.
-
-Each **Authoring** link points to the canonical evals Agent Spec at exact commit
-`e9b53e79b05b1c0e1d7eea02db2eaba47376fe05`, which is pinned to st2
-`9887b28`. It is the authoring authority, not proof of current st2 runtime
-behavior. **st2 source** and **Evidence** links show this implementation on the
-PR base.
-
-## Shared declaration admission
-
-st2 and managed publishers consume one declaration boundary from
-the `agent-spec` library. They do not maintain sibling KDL parsers or reconstruct
-declarations from runner-normalized `AgentSpec` values.
-
-```text
-exact UTF-8 source bytes
-        |
-        v
-agent-spec lossless declaration parser
-        |-- typed KDL tree, order, duplicates, spans, exact source
-        `-- syntax and declaration-shape diagnostics
-                  |
-                  v
-        core Agent Spec admission
-          |                    |
-          v                    v
-   st2 catalog policy     managed publisher
-          |                    |
-          `---------+----------'
-                    v
-          digest-bound publication
-```
-
-### Strict and lossless are separate properties
-
-The parser retains the exact source bytes and a typed tree containing every
-node, argument, property, child, duplicate occurrence, source order, and source
-span. An unknown provider field therefore remains available to its owning
-policy; parsing never makes it valid by dropping it. Publication writes the
-captured bytes, not a serialization of the typed tree.
-
-Strict parsing rejects invalid KDL and declaration-shape errors such as an
-unexpected top-level node, a task without its required name, or a reserved but
-unsupported construct. It does not silently substitute a default for a value
-whose supplied type or shape is invalid. Syntax failure has no document;
-shape failure retains the document for diagnostics but cannot be admitted.
-
-The shared result has this semantic shape:
-
-```rust
-struct DeclaredParse {
-    document: Option<DeclaredDocument>,
-    diagnostics: Vec<AdmissionDiagnostic>,
-}
-
-struct DeclaredDocument {
-    source_name: PathBuf,
-    source: String,
-    nodes: Vec<DeclaredNode>,
-    agents: Vec<DeclaredAgent>,
-}
-```
-
-Convenience accessors may select a field, but the underlying collection remains
-ordered and duplicate-preserving. A policy that requires uniqueness checks the
-collection; it cannot inherit first-wins or last-wins behavior from an accessor.
-
-### Policy layers add constraints without reparsing
-
-Admission is the conjunction of ordered layers over the same immutable
-`DeclaredDocument` and exact source digest:
-
-| Layer | Owner | Decides |
-| --- | --- | --- |
-| syntax and declaration shape | `agent-spec` | whether a complete lossless typed document exists |
-| core Agent Spec | `agent-spec` | canonical field types, uniqueness, normalization, and core invariants |
-| catalog and runtime | st2 | target identity, full-catalog conflicts, host projection, and publication safety |
-| managed declaration | managed publisher | managed launch, persona, Resource, provenance, and provider-specific constraints |
-
-st2 never reports that managed policy passed, and a managed publisher never substitutes its own
-answer for core admission. The managed publisher consumes the shared parse and core result, then
-adds managed diagnostics. This makes a stronger managed refusal and a weaker
-core acceptance explicitly different policy verdicts rather than contradictory
-parses. A publication request fixes the ordered policy profile for that request;
-the receipt names the profile and binds it to the candidate digest.
-
-### Diagnostics are structured data
-
-Every layer emits the same diagnostic envelope. Stable automation branches on
-`code`, `severity`, and `layer`, never on prose.
-
-```json
-{
-  "schema": "st2.agent-spec-diagnostic.v1",
-  "code": "task-name-missing",
-  "severity": "error",
-  "layer": "declaration",
-  "source": "agents/example/worker/agent.kdl",
-  "span": { "offset": 42, "length": 3, "line": 3, "column": 3 },
-  "fieldPath": ["agent", "worker", "pty"],
-  "message": "pty task must have one positional string name",
-  "help": null
-}
-```
-
-`layer` is one of `syntax`, `declaration`, `core`, `catalog`, `managed`, or
-`publication`. `source`, `span`, `fieldPath`, and `help` are optional only when
-the failing layer has no corresponding source location. Human rendering may add
-context, but JSON preserves the envelope and all causal diagnostics. Dependency
-and I/O failures use their own codes and retain the failing path or operation;
-they are not collapsed into an "invalid JSON" or generic admission message.
-
-## Digest-bound publication and re-admission
-
-Publication separates the core transaction st2 can prove under its catalog lock
-from the stronger verdict owned by a managed publisher:
-
-```text
-managed publisher           st2                         live catalog
- |                           |                              |

- | candidate, digest C       |                              |
- |--- publish(C, expected) ->|                              |
- |                           | acquire local authoring lock |
- |                           | re-capture candidate == C    |
- |                           | core-admit locked overlay    |
- |                           | atomic durable replace ----->|
- |                           | read back == C               |
- |                           | core re-admit published view |
- |<-- receipt(C, before, C)--| release lock                 |
- | read live == receipt C    |                              |
- | core + managed re-admit   |                              |
- | report managed success    |                              |
-```
-
-The st2 transaction performs these steps in order:
-
-1. Capture the candidate into immutable staging, retain its exact bytes and
-   typed declaration, and compute its lowercase SHA-256 source or bundle digest.
-2. Acquire the catalog's exclusive local authoring lock. No cross-host lock,
-   external lock service, or shared receipt is involved.
-3. Re-read the current target under the lock and require the caller's exact
-   absent-or-SHA-256 precondition. Require the staged digest to equal the
-   caller's input digest. When that incumbent carries an ownership marker and
-   the candidate would replace its bytes, require the caller to assert exactly
-   that marker with `--managed-by`: an unasserted replacement refuses for the
-   Nix marker, and a mismatched, unmarked, unresolvable, or malformed assertion
-   always refuses — here, before any write. Creation and a byte-identical
-   republication replace no owned bytes and need no assertion.
-4. Overlay the staged candidate on the locked catalog snapshot and run shared
-   parsing, core admission, and st2 catalog policy over that exact projection.
-5. Publish by an atomic, durable file or bundle transition. Preserve exact
-   candidate bytes and synchronize the containing directory before success.
-6. While retaining the lock, open the published regular file without following
-   symlinks, require its digest to equal the input digest, and rerun shared parse,
-   core admission, and catalog policy against the published view.
-7. Commit the catalog generation and return a typed receipt containing the
-   policy profile, input digest, before digest when present, and verified after
-   digest. Only then release the lock.
-
-Failure before the atomic transition publishes nothing. Failure after it never
-returns a success receipt: the catalog transaction restores only when its
-generation record proves the exact previous bytes and target; otherwise its
-durable recovery state reports an indeterminate publication and blocks dependent
-work. Re-admission is not replaced by comparing bytes alone.
-
-For a managed publication, the publisher binds its candidate verdict to the same input
-digest, accepts only a matching st2 receipt, then reads the live declaration and
-reruns shared parse, core admission, and its managed policy. It reports managed
-success only when the live digest still equals the receipt's verified after
-digest. A later writer produces `superseded`, not a false success or an
-unproved rollback. st2 mutation commands that apply only core policy report a
-core publication and do not claim managed admission.
-
-## Field rules
-
-### F01 Source form or path
-
-Formatting, comments, order, and a source path change are `no-op` only when all
-normalized fields, render plans, task IDs, fallback `cwd`, exact resolved paths,
-and Resource references match. Otherwise, classify the changed effect. A
-`no-op` writes and notifies nothing but does not block healing of absent or dead
-work.
-
-Authoring: [pinned discovery, identity, and host][evals-discovery]. st2 source:
-[KDL parser](../../../crates/agent-spec/src/kdl_format.rs). Evidence:
-[discovery](../../../crates/agent-spec/src/discovery.rs).
-
-### F02 Agent `id` and legacy `identity`
-
-The target `id` field is the immutable catalog-global agent ID. IDs are unique
-across live and structurally archived subjects, across hosts and desired states.
-Subject-creation tools generate UUIDv7. Before ID-aware routing activates,
-migration assigns every live legacy declaration its existing
-`<resolved-host>.<identity>` bus identity as an explicit ID without moving
-runtime or declaration-anchored state. An archived declaration receives those
-same bytes when unused in the combined subject set; a collision receives UUIDv7
-in its declaration and tombstone. Migration also records each reassigned legacy
-bus identity with the subject that kept it and the archived subject's new ID so
-readers of legacy records never retype colliding bytes into the wrong subject.
-Supervisor resolution uses the combined
-pre-migration live-and-archived subject index. In the same catalog transition,
-every reference is rewritten to the parent's migrated ID. A missing or ambiguous
-reference refuses before writes with `legacy-supervisor-unresolved`; the
-operator must unarchive and repair that declaration through the pre-activation
-legacy authoring path, then retry. Unarchive preserves and validates the
-migrated ID and refuses an unmigrated archive after activation. A frozen legacy
-ID remains unchanged after host moves.
-
-Agent-declaration membership is keyed by ID. Adding a generated ID creates a
-new subject. Reintroducing an earlier ID denotes the same subject and may adopt
-only state proved to belong to that ID; it never denotes a replacement.
-Removing a declaration plans teardown for that exact subject. A candidate that
-changes `id` at one declaration source refuses rather than inferring rename,
-replacement, or state migration. Positional `identity` remains the declaration
-key and address fallback; it is not immutable subject identity.

-
-Each supervisor evaluates only local membership. A complete present-to-absent

-### F09 Task set: `pty`, `exec`, or compact `ding`

-that target is held, fails to restart, or is terminally parked, do not launch
-the derived child and stop an exact generated child proved live. Explicit
-sibling tasks, including an authored `exec "ding"`, remain independent. Do not
-change unrelated siblings.
-
-Before compact tasks are compiled, st2 captures its current absolute executable
-once. A generated DING lowers to direct argv using that executable, the agent's
-immutable ID through an exact-ID selector, and its effective absolute bus root.

-### F12 Future policy (R31)
-
-```text
-canonical catalog folder + host = supervisor scope
-                            |
-                            v
-                      supervisor run
-                            |
-             park marker <--+--> unpark request
-```
-
-Agent or task `keep`, restart `attempts`, `interval`, `delay`, and `mode`, and
-task `lifecycle` are future policy. Adopt healthy work. `adopt-only` holds absent
-or dead work; `service` reconciles it normally. A generated companion follows
-the canonical agent's effective eligibility: `adopt-only` holds it, and
-exhausting a fail-mode restart policy stops or suppresses it. Invalid policy
-refuses changes to the related agent and tasks.
-
-`delay` is the minimum spacing between launches in either restart mode. In
-`mode = delay`, `attempts` is a rate limit over the sliding `interval` window;
-an exhausted limit defers launch until the window clears and never parks the
-task. In `mode = fail`, `attempts` is a terminal launch budget counted since
-the task was observed alive on every completed accounting pass for a full
-`interval`. The budget remains reachable independent of reconcile cadence: a
-task that repeatedly launches and dies before recovery is parked after its
-declared successful-launch budget is exhausted. A completed accounting pass
-that does not observe the task alive breaks accrued recovery uptime rather than
-forgiving failures through silence.
-
-A parked task is reported as parked by the typed task inventory, carrying when
-it was parked, why, and what clears it, alongside an unmodified runtime
-observation. The park is a supervisor decision about the runtime rather than an
-observation of it, so it never replaces the observed state and never makes the
-inventory envelope incomplete. Its recovery action is structured executable
-argv that carries the inventory's exact canonical catalog folder and selected
-host, so an operator can invoke it without ambient ownership defaults changing
-the target supervisor scope.
-
-Parking is terminal within its owning supervisor run, and its only per-task exit
-is an explicit operator unpark request granted by that run. Granting one clears
-exactly that task's park and restart accounting, so the next launch spends a
-full budget; it never releases another parked task and never restarts a healthy
-one. A request naming a task that is not parked is reported as recovering
-nothing. A published park belongs to the supervisor run that made it: a
-projected park whose supervisor is gone is positively not parked.
-
-The park projection and unpark request channels share one supervisor scope: the
-exact canonical catalog folder plus host. Both marker publication/observation
-and request publication/consumption derive that scope identically. Supervisors
-for different catalog folders on the same host cannot see or delete each
-other's markers or consume each other's requests, including when the task IDs
-are identical. There is no host-only compatibility channel or task-specific
-namespace exception.

-### F13 `retired #true`
-
-Fence, stop, and clean every declared task ID with exact ownership proof, and
-prevent relaunch. Retirement preserves the agent ID, removes the subject from
-ordinary address routing, and releases its effective address after the retired
-catalog generation becomes visible. Suspending a subject does not release its
-address. Declaration removal follows F02's exact ID-keyed membership rule; a

-[reconciliation](../../../src/reconcile.rs).
-
-### F18 `desired-state` and `reason`
-
-`desired-state` is one of `running`, `suspended`, or `retired`. Its omission is
-running. A suspended or new-style retired declaration carries exactly one
-`reason` property of 1..160 UTF-8 bytes with no surrounding whitespace,
-controls, or Unicode line separators. Running carries no reason. Legacy
-`retired #true` remains readable without a reason; any declaration containing
-both lifecycle forms is invalid.
-
-Running enters the ordinary field rules. Suspended and retired declarations
-fence launch and materialization, then remove their exact live task set,
-including generated companions. A suspended declaration is healthy when no
-task is live and every retained dead record is explicitly keep-pinned. A
-retired declaration is complete only when every declared task record is
-absent. Resume does not override `keep`, `adopt-only`, ownership proof, or
-drift/replacement policy. Inbox, archive, context, resources, and presence files
-remain addressable through exact agent ID; retirement removes only ordinary
-address routing.
-
-The canonical KDL authoring form is:
-
-```kdl
-desired-state "suspended" reason="Waiting for capacity"
-```
-
-The safe authoring surface is
-`st2 agent desired-state --id <agent-id> <state> [--reason ...]
-[--managed-by <marker>]`. It serializes with other catalog writers, preserves
-unrelated source bytes, and returns an authored-intent receipt. While holding
-the catalog-authoring lock, every lifecycle mutation constructs one prospective
-shadow and compares incumbent and prospective core `ERROR` identities as
-`(code, catalog-relative path, agent)` multisets. A positive delta refuses
-before publication; messages are not identities because they may contain the
-shadow path. This admits repair and teardown despite unrelated pre-existing
-errors while preventing a transition from introducing an error. Entering
-running activates launch-readiness and address checks. Entering suspended
-reacquires address and topology checks without launch readiness. Entering
-retired applies retirement topology checks. The receipt does not imply that
-reconciliation or Doctor has observed convergence.
-
-A declaration carrying `meta { managed-by "nix" }` refuses authoring unless the
-caller asserts exactly the marker that declaration carries with `--managed-by`,
-which is how a projection authors the one transition its own generated source
-cannot express — the seat's removal from that source. The asserted arm uses the
-same lifecycle-delta admission as ordinary authoring, and the receipt records
-the confirmed marker. Every other
-authoring verb refuses a Nix-owned declaration unconditionally.
-
-The exact-ID selector and reactivation validation are target behavior fenced by
-[DELTA-003](../.delta/DELTA-003-agent-address-not-implemented.md); the linked
-current evidence still exercises the positional legacy selector.

-### F21 Agent `residency-policy`
-
-`residency-policy` is one positional string: `always` or `on-demand`. Omission
-means `always`, and explicit `always` is semantically equal to omission.
-Duplicate nodes, annotations, properties, children, non-string values, and
-unknown values are invalid. TOML and JSON use `residency_policy`; explicit null
-is invalid.
-
-`on-demand` requires a native session driver, either through `session-driver`
-or a typed driver block. The field grants residency eligibility only while
-`desired-state` is running. It does not change desired state, task lifecycle,
-restart policy, delivery ownership, or provider state. Suspended and retired
-declarations continue to use F18 exclusively.
-
-Changing this field is a semantic catalog change. `st2 tasks --json` exposes
-the declared policy separately from the nullable host-local runtime-residency
-record. Host policy owns timing and warm capacity; neither belongs in the Agent
-Spec.
-
-st2 source: [`ResidencyPolicy`](../../../crates/agent-spec/src/spec.rs),

-
-### F17 Agent `name` and `description`
-
-Update observable declaration and runtime presentation metadata only. Neither
-field participates in agent ID, address routing, selection, authorization,
-state paths, launch fingerprints, workspaces, inbox events, DING, or
-lifecycle. The roster reads the declaration directly; sibling `name` files are
-ignored.
-
-External harness consumers read the current Agent Spec rather than a duplicate
-derived file. `st2 agents --id <agent-id> --json` returns exactly one immutable
-subject or fails; in-process drivers may consume the same lowered `AgentSpec`
-directly. Both paths preserve explicitly nullable name and description and
-grant no lifecycle authority.
-
-For a healthy managed PTY, patch the exact runtime task ID in place. Every PTY
-receives the schema-2 owned actor-ID, current-bus-address, and
-optional-description tag snapshot. Only the primary task named `agent` carries
-the compatibility role and maps optional name to native display metadata.
-Clearing removes only the corresponding st2-owned value. Preserve unrelated
-tags and secondary display conventions. An unchanged projection is a no-op.
-Failure reports and retries without stop, reap, restart, replacement, or
-flapping accounting. Absent work receives the same projection at spawn.

-
-### F19 Agent `stream`
-
-A `stream "<name>" {}` declares one agent-owned event ingress endpoint. Names
-are 1..=40 lowercase alphanumeric characters with optional interior hyphens
-and cannot collide with an authored task named
-`stream-<name>`. The declaration contains at most one launch: `command` is an
-opaque shell command, `argv` is a non-empty structured argument vector, and an
-empty body means external ingress. Unknown children, including the reserved
-`every`, fail admission.
-
-A launched stream adds exactly one derived exec task named `stream-<name>` with
-default runtime ID `<agent-id>.stream-<name>`. Its authored `command` or `argv`
-lowers directly to that task; no stream runner or stdout line protocol is
-inserted. An external-ingress stream adds no task. Adding or removing a launched
-stream therefore adds or removes that exact derived companion under the owning
-agent's lifecycle; changing its launch is spawn-input drift under F11. It does
-not change the canonical agent task or select a delivery transport.

-and stream lifecycle tests in [`tests/run.rs`](../../../tests/run.rs).
-
-### F20 Agent `address`
-
-`address` is an optional mutable semantic alias for human routing. Its omission
-uses positional `identity` as the effective legacy address. Its presence
-replaces that fallback immediately; the prior value receives no alias,
-redirect, or history. An explicit address is at most 255 ASCII characters and
-is a dotted sequence of 1-to-63-character segments. Each segment contains only
-lowercase letters, digits, and hyphens and begins and ends with a letter or
-digit.
-
-The complete prospective catalog requires effective addresses to be unique per
-resolved logical host among running and suspended subjects, including
-collisions between explicit addresses and identity fallbacks. Retired subjects
-are non-routable and do not occupy the namespace.
-Address and ID are separate typed namespaces; equal bytes do not collide.
-
-An ordinary unpinned reference tries the complete input as a bare address and
-every dotted split whose prefix is an admitted host and suffix is an effective
-address in that host. A host-pinned reference tries the complete input as an
-address in that host plus the qualified split whose prefix equals the pinned
-host. Candidates are deduplicated by agent ID; exactly one distinct subject
-must remain. An explicit typed ID bypasses this algorithm.
-
-An address-only change updates the catalog address book and runtime metadata
-without changing immutable ownership, ID-keyed supervisor edges, task IDs,
-launch fingerprints, workspaces, declaration-parent state paths,
-inbox/archive/context/Resource data, or a healthy runtime incarnation.
-
-The safe authoring surface is
-`st2 agent address --id <agent-id> (--clear | <address>)`. It uses the same
-source-preserving, authority-scoped, stale-writer-refusing, durable catalog
-transaction as F17. Clearing restores the identity fallback and is refused
-when that fallback conflicts on the resolved host.

-`agent_author` integration. Required evidence: parser and validation tests;
-host-local collision tests including legacy fallbacks; atomic cutover and
-stale-reader fencing; explicit-ID versus ordinary-address selection; no-restart
-continuity across task/PTY, bus, provider, and durable-state surfaces; and
-separate host/launch lifecycle controls.
-
-Catalog and PTY roots are host runtime inputs, not Agent Spec fields. Their
-migration contract is outside this VRS. See
-[#85](https://github.com/compoundingtech/st2/issues/85).
-
-## Address cutover and unsupported redirects
-
-F20 is an atomic same-subject address-book cutover, not a moved-intent record.
-The old effective address becomes unclaimed when the new catalog generation is
-visible. The model has no alias, redirect, route history, expiry, cycle, or
-pending-map state. An implementation that needs any old-address compatibility
-must return to requirements design rather than adding an inferred fallback.
-
-The parser and runtime do not yet support F20. The implementation gap is
-recorded in the root identity delta.
-
-## Execution order
-
-Plan the snapshot, normalized difference, ownership, conflicts, and rollback.
-Refuse before mutation when a required proof is missing. Then omit empty phases
-from this fixed order:
-
-1. **FENCE:** prevent launch of old, replaced, suspended, and retired IDs.
-2. **REMOVE/QUIESCE:** stop exact old incarnations and release their resources.
-3. **MATERIALIZE:** write final state for survivors and additions.
-4. **ADD/BOOT:** boot missing or explicitly replaced work from final bytes.
-5. **NOTIFY:** notify survivors after commit and coalesce related changes.
-6. **VERIFY/REPORT:** verify exact results; roll back only when proved,
-   otherwise hold or refuse.
-
-Independent agents, tasks, and files progress separately when their input and
-ownership proof are complete. The order does not coordinate hosts or authorize
-replacement of drifted work.
-
-## Current implementation gaps
-
-- **G01, F01/F04/F15:** the prepared-catalog diff exposes normalized Agent
-  Spec-model field differences, but effect-level path normalization and watcher
-  consumption remain absent, and invalid KDL `type` can lower to `service`.
-  [Parser](../../../crates/agent-spec/src/kdl_format.rs)
-- **G02, F06-F08:** render ownership and idempotent writes exist, but dependency
-  targeting and post-commit notification do not. [Materializer](../../../src/materialize.rs)
-- **G03, F02/F09-F13:** ID-only adoption lacks fingerprint and incarnation
-  binding. Exact removal and simultaneous remove/retire are absent. Malformed
-  restart fields use defaults. See [#40](https://github.com/compoundingtech/st2/issues/40),
-  the [model](../../../crates/agent-spec/src/spec.rs), and
-  [reconciler](../../../src/reconcile.rs).
-- **G04, F06/F11:** workspace is the current startup `cwd` fallback, not live
-  context. [Runner](../../../src/run.rs)
-- **G05, F03:** host filtering exists, but exact old-projection removal does
-  not. No cross-host mechanism is required. [Host filter](../../../src/reconcile.rs)
-- **G06, notifications:** inbox and PING exist, but reconciliation writes no
-  stable change event. [Message](../../../src/message.rs) and
-  [PING](../../../src/ding/mod.rs)
-- **G07, planning/reporting:** st2 cannot plan and commit all related agent,
-  task, and file changes as one operation, and it has no true dry-run;
-  `materialize-only` writes. See [#53](https://github.com/compoundingtech/st2/issues/53)
-  and [runner](../../../src/run.rs).
-- **G08, F02/F20 identity migration and address routing:** the explicit `id`
-  field, legacy ID migration, address parser, address-book resolver, roster and
-  graph projection, and address authoring are absent.
-- **G09, F17 release ordering:** source authoring requires Nix emitters to mark
-  generated declarations before the compatible st2 binary is activated. The
-  pinned merged PTY dependency provides the exact-ID atomic metadata-patch API;
-  compatible st2 and Nix provenance adoption must still deploy as one gated cohort.
-- **G10, shared admission:** st2 runner lowering, st2 publication, and
-  managed admission do not yet consume one complete core-policy result and one
-  structured diagnostic envelope. Publication verifies exact digests and a
-  full-catalog overlay before its atomic transition, but must also re-admit the
-  published view under the lock and bind the policy profile in its receipt.
-- **G11, F19 canonical ownership:** st2 admits, lowers, authors, and runs the
-  `stream` field, but the canonical evals `AGENT-SPEC.md` and its maintained
-  acceptance evals do not yet define or prove that capability. Until the
-  matching evals change lands, st2's stream implementation is ahead of the
-  authoring authority rather than conformant to it.
-
-## Acceptance cases
-
-- Source `no-op` changes nothing while an independently dead task still heals.
-- Lossless parsing preserves unknown fields, duplicates, order, exact source,
-  and spans. Syntax and shape mutations produce stable structured diagnostics;
-  no invalid supplied value becomes an omitted default.
-- st2 core admission and managed admission consume the same parsed document
-  and core verdict. A managed-only refusal is labeled as managed policy, while a
-  core error blocks both without a second parse or contradictory message.
-- Concurrent publication proves the caller's before and input digests under the
-  catalog lock. The success receipt follows read-back and core re-admission of
-  the exact published digest; managed success additionally follows publisher
-  re-admission of that same live digest. A superseding writer is reported as
-  `superseded` rather than success.
-- Role and policy changes preserve healthy work; invalid values refuse.
-- A workspace survivor gets one event. Absent or dead work boots the latest
-  workspace. Explicit task `cwd` drift stays visible.
-- Changed render or Resource state commits before one combined event. Unchanged,
-  failed, rolled-back, periodic, new, replaced, suspended, and retired paths emit none.
-- DING failure retains the event. Replay has no extra effect, and inbox events
-  do not cause inbox events.
-- Task add, remove, rename, and retirement affect exact runtime IDs, including
-  simultaneous child removal. Legacy or partial proof holds or refuses.
-- Suspension stops the exact live task set, including a derived DING, while an
-  unrelated sibling retains its generation and a durable inbox message retains
-  its filename. Resume uses ordinary keep/adopt-only/service rules. Doctor
-  accepts only no-live plus keep-pinned dead records for suspension and still
-  requires complete record absence for retirement.
-- Matching fingerprints adopt. Mismatches drift. Explicit replacement proves
-  the exact incarnation through fence, quiesce, materialize, and boot.
-- Name and description changes update the exact Agent Spec roster row and PTY
-  metadata while task ID, PID, creation identity, and generation remain
-  unchanged. Exact agent-ID roster selection returns one row or fails without
-  publishing duplicate presentation state. Clearing removes only owned
-  presentation values. A genuine retirement still follows ordinary teardown.
-- Address assignment, change, clearing, and old-address reuse prove one atomic
-  before-or-after address book, fail stale routes immediately, update roster
-  and PTY metadata, and preserve the healthy runtime and durable subject state.
-  Host changes preserve logical agent ID but follow the existing host-placement
-  lifecycle rather than the nondisruptive address rule.
-- A refusal for one related set of agents, tasks, or files does not block
-  independent work whose input and ownership proof are complete. Every result
-  names the affected IDs, action, and what the proof covers.

-# Doctor requirements
-
-Doctor checks one catalog from one host. It follows the root
-[vision](../vision.md). It refines [R03](../requirements.md),
-[R04](../requirements.md), and [R08](../requirements.md).
-It does not define fleet health.
-
-## Requirements
-
-- **DOCTOR-R01 Diagnostic subject:** One run checks one selected catalog and one
-  selected host. The result does not claim that a remote host is available.
-- **DOCTOR-R02 Gate result:** A healthy result returns zero. Any diagnosed
-  problem returns non-zero. Each problem names the affected declaration, task,
-  runtime, catalog, or supervision subject.
-- **DOCTOR-R03 Read-only diagnosis:** A run must not change catalog, presence,
-  or runtime state. It must not reconcile, launch, stop, reap, repair, or
-  materialize work.
-- **DOCTOR-R04 Bounded non-interactive operation:** Doctor and its external
-  probes must not read the caller's standard input. A probe must stop within a
-  fixed time. A timed-out probe is a failed check, not a hung caller.
-- **DOCTOR-R05 Active local health:** Doctor checks each active declaration on
-  the selected host. It checks that declared work is alive and that presence is
-  maintained. It does not check remote availability.
-- **DOCTOR-R06 Retired absence:** A retired declaration is healthy only when all
-  declared task records are absent. A live or dead record is unhealthy. A
-  retired declaration does not require presence or active-declaration checks.
-- **DOCTOR-R07 Suspended absence:** A suspended declaration is healthy only
-  when no declared task is alive and every retained dead task record is
-  explicitly keep-pinned. It does not require presence or active-declaration
-  checks. A dead non-keep record is unhealthy because ordinary reconciliation
-  still owes its collection. This weaker predicate does not satisfy retirement.
-- **DOCTOR-R08 Outbound message health:** Doctor validates each local agent's
-  sender ledger without creating or repairing sender state. An invalid ledger
-  is a failed check that says the agent cannot send. An unavailable ledger is
-  healthy because no sender history exists.
-
-The [Retirement health invariant](../../../docs/st2/invariants.md) and its tests prove
-the retirement rule. The [specification](spec.md) owns the mechanism, check
-groups, and known gaps.

-# Doctor specification
-
-This document maps the [Doctor requirements](requirements.md) to the current
-CLI, implementation, and tests. It does not define check order, private
-filenames, exact report text, or fallback behavior.
-
-## Scope and inputs
-
-The [`doctor` CLI](../../../src/main.rs) selects a catalog and a host.
-Shared catalog rules resolve the catalog. The caller can select a host, or st2
-can detect the local host. The `--require-supervisor` flag requires a resident
-`st2 up` process. Without this flag, manual and one-shot operation are valid.
-The report names the resolved catalog and host.
-
-## Checks
-
-[`doctor_cmd`](../../../src/main.rs) is the implementation authority.
-It performs these check groups:
-
-- **Environment:** The required runtime tools are available
-  ([source](../../../src/main.rs)).
-- **Supervision:** The host mode matches the caller's request
-  ([source](../../../src/main.rs); [tests](../../../tests/doctor.rs)).
-- **Catalog:** The selected catalog has no discovery errors
-  ([source](../../../src/main.rs)).
-- **Runtime:** Runtime state is readable, and each active local task is alive
-  ([Doctor source](../../../src/main.rs); [unified runtime view](../../../src/run.rs)).
-  The PTY probe has a fixed deadline and closed standard input
-  ([probe source](../../../src/run.rs); [tests](../../../tests/doctor.rs)).
-- **Presence:** Each active local declaration has maintained presence
-  ([source](../../../src/main.rs)).
-- **Outbound messages:** Each local declaration has a valid sender ledger. An unavailable ledger is
-  healthy because the agent has not sent a message. An invalid ledger reports that the agent cannot
-  send. Doctor does not create or repair sender state.
-- **Retirement:** Every task record for a retired local declaration is absent
-  ([source](../../../src/main.rs); [tests](../../../tests/doctor.rs)).
-- **Suspension:** No task of a suspended local declaration is alive. A dead
-  record is accepted only when the task or agent is keep-pinned; presence is
-  not required. This remains distinct from retirement's full-record absence
-  ([source](../../../src/main.rs); [tests](../../../tests/doctor.rs)).
-
-## Output contract
-
-Doctor writes a human-readable report for the resolved catalog and host. Each
-failure has a subject label and available detail. Doctor returns zero only when
-it diagnoses no problem. The formatter and result are in
-[`report_check`](../../../src/main.rs) and
-[`doctor_cmd`](../../../src/main.rs). The
-[clean-path test](../../../tests/native_only.rs) proves that the CLI
-does not need a predecessor transport.
-
-## Open questions
-
-These are implementation gaps or unsettled product choices, not requirements:
-
-- **Malformed presence:** Unreadable or invalid fresh presence becomes
-  `offline`. Should Doctor report corruption separately?
-  ([source](../../../src/status.rs))
-- **Exec enumeration bound:** Exec record enumeration is synchronous file-system
-  work. It is outside the PTY deadline. What deadline should cover the full
-  diagnosis? ([source](../../../src/exec_backend.rs))
-- **Tool dependency:** Doctor requires `pty` when a host has only exec tasks.
-  Should the declared tasks select the required tools?
-  ([source](../../../src/main.rs))
-- **Machine output:** Doctor has no stable machine-readable report. Should it
-  provide structured findings in addition to the exit status?
-  ([CLI surface](../../../src/main.rs))

-# Sender history crash model
-
-## Question
-
-Can a sender-owned durable intent bridge recipient-first and sender-row publication without false
-Sent, silent recipient-only completion, or duplicate keyed retries, without claiming
-cross-directory atomicity?
-
-## Method
-
-### Alternatives
-
-| Design | Recipient deletion | Crash between writes | Identical intentional sends | Result |
-| --- | --- | --- | --- | --- |
-| Scan all recipient inboxes and archives | Loses history | No sender recovery state | Distinct | Rejected |
-| Publish sender row first | Preserves history | Can report false Sent | Distinct | Rejected |
-| Write recipient then sender without intent | Preserves completed history | Can leave silent recipient-only delivery and duplicate a retry | Distinct | Rejected |
-| Deduplicate by payload hash | Preserves history | Can reuse a write | Collapses legitimate identical sends | Rejected |
-| Full mutable manifest | Preserves history | Rewrites O(history) state per send | Distinct | Rejected |
-| Mutable append log | Preserves history | Torn tail needs a second recovery protocol | Distinct | Rejected |
-| Count or per-row marker without a linked head | Cannot detect loss or substitution | Incomplete trust root | Distinct | Rejected |
-| New database | Preserves history | Adds an unnecessary storage subsystem | Distinct | Rejected |
-| Linked immutable commit ledger | Preserves history | Explicit partial state and resumable filename | Distinct unless the caller supplies the same key | Selected |
-
-Typed `request` publication supplied the reservation precedent: persist the chosen filename and
-rendered bytes before idempotent recipient materialization. Its service-principal records remain
-outside ordinary Sent history.
-
-### Prototype
-
-A pure throwaway state model used one constant head, one active pointer, immutable rows, and immutable
-content-addressed commit nodes. It enumerated eight ordered steps after coverage initialization:
-
-1. create pending,
-2. publish active,
-3. materialize the recipient,
-4. create the sender row,
-5. create the linked commit node,
-6. atomically advance the head,
-7. clear pending,
-8. clear active.
-
-The model injected a crash before and after every step. Recovery then had to satisfy every oracle:
-
-- every sender row's filename exists in the recipient set,
-- coverage is never `since` while intent is pending,
-- exact traversal reaches genesis in the head's declared count,
-- every node digest, predecessor, ordinal, and row digest verifies,
-- reachable node and row sets exactly match their directories except state explained by active,
-- orphan pending is partial and recoverable,
-- head-advanced stale active or pending state cleans up without republishing.
-
-Thirteen falsifiers removed or substituted the head, node, or row; added unexplained state; changed
-digest, predecessor, ordinal, count, genesis, or version; and required rejection. The head is the
-bounded trust root. Coordinated adversarial rewrite of that head plus all matching sender state is
-outside the local loss and corruption contract.
-
-### Performance
-
-Run the exact candidate binary against one captured real catalog with at least 557 discovered agents
-and at least one sender-owned row. Verify both counts first. For `message sent <sender> --json` and
-the same catalog's `message ls <sender> --json`, run one untimed warm-up followed by ten independent
-timed invocations. Record each wall-clock duration in milliseconds, sort each ten-sample series, and
-take nearest-rank p95 (sample 10). Record `sent p95 / message-ls p95`. Sent p95 must be no greater
-than 1.0 second and no greater than twice message-ls p95.
-
-The benchmark must leave an unrelated recipient box structurally unreadable while Sent still returns
-the sender rows. It reports the exact Git commit, catalog agent count, sender row count, both exact
-commands, both ten-duration series, both p95 values, and the ratio. Synthetic or empty sender data is
-not a substitute for this axis.
-
-## Result
-
-### Prototype and executable controls
-
-The prototype returned
-`{"result":"pass","crashCases":9,"corruptionCases":13,"writeComplexity":"O(1) history","readComplexity":"O(history)"}`.
-
-The first ledger run exposed one boundary the simpler active/pending rule missed: after the head
-advances, active may remain while pending cleanup has already completed. The head proves that active
-pointer is stale recoverable state. Before head advancement, active without its matching pending
-record fails closed.
-
-The model's invariants are executable in
-`tests/message_cli.rs::keyed_retry_recovers_every_crash_boundary_without_false_sent_or_duplicates`.
-The shared coverage and row contract is executable in
-`crates/fractal-wire/src/message.rs::sent_rows_carry_to_and_coverage_never_collapses_unavailable_into_empty`.
-The structural RED control makes an unrelated recipient box unreadable before Sent enumeration; a
-recipient-scanning implementation therefore fails while a sender-owned implementation succeeds.
-The throwaway driver is not part of the repository.
-
-### Benchmark
-
-Pending exact-candidate Sent and same-sender message-ls measurement. No performance result is claimed
-until both p95 values and their ratio are recorded under the method above.
-
-## Conclusion
-
-The linked ledger satisfies the bounded crash/retry and corruption oracles. Recipient-first ordering
-prevents false Sent. The constant head makes every completed prefix verifiable without O(history)
-write work. Durable pending and active state make intermediate writes explicit and resumable.
-Unkeyed post-commit response ambiguity remains the declared at-least-once tradeoff.
-
-## VRS Impact
-
-The selected invariants define `MESSAGE-R03` through `MESSAGE-R08` and the transaction, coverage, and
-retry sections of [`../spec.md`](../spec.md). The pending performance result gates `MESSAGE-R10`.

-# Message requirements
-
-## Context
-
-This subsystem defines the native message bus beyond terminal delivery. It
-refines root requirement [`R05`](../requirements.md) for durable message
-publication and inherits immutable agent ID and mutable address semantics from
-`R19` and `R24`. DING consumes the recipient inbox under
-[`01-ding/requirements.md`](../01-ding/requirements.md); this subsystem does not
-redefine terminal delivery.
-
-## Assumptions
-
-- **MESSAGE-A01 Declared senders:** A catalog-backed ordinary sender is an Agent Spec identity. The
-  eval-owned external requester remains an explicit compatibility capability because the canonical
-  eval flow requires one non-Agent requester mailbox. A message with that capability at either
-  endpoint is external eval traffic, not ordinary Agent Sent history, and does not weaken the
-  Agent-only ownership contract.
-- **MESSAGE-A02 Local publication filesystem:** One send executes against one selected catalog
-  filesystem. Replication and network delivery remain eventual under root `A04`.
-- **MESSAGE-A03 Bounded local trust root:** The atomically replaced sender head is the local
-  completeness trust root. Coordinated replacement of that head and every matching sender record is
-  outside the local loss and corruption contract.
-
-## Acceptable Tradeoffs
-
-- **MESSAGE-T01 Ordered local commits:** Recipient and sender directories do not commit atomically.
-  st2 may expose a pending sender intent after interruption, but it must not expose a completed sent
-  row before recipient publication.
-- **MESSAGE-T02 Forward coverage:** st2 does not reconstruct sender history that predates the first
-  sender-index marker. The API reports that boundary instead of presenting historical absence as an
-  empty complete result.
-- **MESSAGE-T03 Unkeyed response ambiguity:** An unkeyed send is at-least-once across a crash after
-  commit but before the caller observes the result. Exact replay safety requires a caller-supplied
-  idempotency key because identical intentional sends and an unkeyed retry are otherwise
-  indistinguishable.
-
-## Requirements
-
-### Must own an honest sender view
-
-- **MESSAGE-R01 Sender-owned enumeration:** Every successful ordinary `message send` and `message
-  reply` by an indexed sender creates one durable sender-owned row. `message sent` enumerates only
-  that sender-owned state; recipient inbox and archive state cannot remove or supply its rows.
-- **MESSAGE-R02 Canonical direction and readable projection:** Ordinary Agent
-  publication resolves each sender and recipient address to one immutable agent
-  ID and persists those IDs as canonical direction and provenance. It also
-  appends each endpoint's publication-time bus address as display-only snapshot
-  metadata. A sent row carries canonical `to`; it does not repurpose the inbound
-  row's `from` field. Inbox rendering includes canonical sender ID and readable
-  sender address. DING resolves the sender ID to its current bus address at
-  delivery and otherwise falls back to the immutable ID, showing the
-  publication snapshot only when it is explicitly marked historical, because a
-  released address is immediately reusable. Replies and automation always use
-  the persisted ID. A separately admitted principal or external endpoint uses an
-  explicit endpoint-kind discriminator and its canonical principal/external
-  address; it is never represented as an agent ID.
-- **MESSAGE-R03 Explicit coverage:** Machine output distinguishes an unavailable index, coverage
-  beginning at one unix-millisecond boundary, and partial coverage with pending intents. An absent
-  or interrupted index must never serialize as a complete empty history. Count output refuses
-  unavailable or partial coverage. A constant-size head commits to an immutable linked ledger of
-  every completed row. Exact traversal to genesis rejects missing, extra, substituted, corrupt,
-  unreadable, or version-mismatched head, node, active-intent, pending, and row state instead of
-  weakening the coverage claim.
-- **MESSAGE-R04 Stable shared wire:** The sent envelope and row are serialized
-  through `fractal-wire`. Optional metadata and body omission preserve absent versus
-  empty values. A durable record version changes whenever an existing field's
-  meaning changes or a strict record gains fields. A reader may reinterpret a
-  version-1 endpoint as an agent ID only for legacy bus identities that
-  migration froze for that same subject. Bytes that migration reassigned away
-  from an archived collision resolve only for the row's own state owner and are
-  otherwise rendered as an unattributed historical address that carries no
-  reply or automation authority; the reader never attributes them to the live
-  subject that kept them.
-
-### Must survive interruption without a false Sent claim
-
-- **MESSAGE-R05 Recipient-first publication:** A send durably reserves sender intent, materializes
-  the recipient copy idempotently, then publishes the sender row. A completed sender row proves that
-  recipient materialization succeeded at least once. st2 makes no cross-directory atomicity claim.
-- **MESSAGE-R06 Resumable intent:** A later sender operation resumes durable pending intents with
-  their original filename and bytes. Interruption cannot create a second recipient filename or a
-  second sender row for the same intent. An exact pending duplicate of the current committed head tip
-  is cleanup state. A read reports completed coverage, and the next sender operation removes it.
-- **MESSAGE-R07 Exact keyed retry:** An idempotency key is scoped by `(canonical sender, canonical
-  recipient, idempotency key)`. Reusing one scoped key with the same message returns the original
-  filename after any publication or response boundary. Reusing that scoped key with different
-  message content fails. The key remains sender-owned even if the recipient deletes its copy.
-- **MESSAGE-R08 Serialized sender writes:** Concurrent sends from one sender serialize through one
-  local kernel lock. Intentional identical unkeyed sends remain distinct; payload equality is not an
-  idempotency key. Each publication performs constant history-dependent write work; enumeration and
-  ledger validation remain linear in sender history.
-
-### Must remain usable as one bounded read
-
-- **MESSAGE-R09 Directional filters:** `message sent [address]` selects the
-  positional address, then `--as`, then the exact acting ID from `ST_AGENT`,
-  and supports an explicit mutually exclusive `--id`. It also supports
-  `--count`, `--include-body`, strict `--since`, JSON, and `--to` as the
-  directional analogue of inbox `--from` wherever coverage can be represented
-  honestly.
-- **MESSAGE-R10 Catalog-scale read:** On one captured real catalog with at least 557 agents and at
-  least one real sender row, one warm-up followed by ten timed reads of both `message sent --json`
-  and same-sender `message ls --json` records both p95 values and their ratio. Sent p95 is no greater
-  than 1.0 second and no greater than twice message-ls p95. The read must not depend on the number,
-  readability, or retention state of recipient boxes; an unrelated recipient box remains
-  structurally unreadable while Sent returns the sender rows without scanning it.
-- **MESSAGE-R11 Typed-request separation:** Service-principal request publication state does not
-  appear in ordinary Agent Sent history unless a later requirement defines that projection. The
-  explicit external-eval requester capability is also excluded whenever it is either endpoint.
-
-## Evidence
-
-The crash and retry state model, alternative analysis, and benchmark method are recorded in
-[`2026-08-12-sender-history-crash-model.md`](./.experiments/2026-08-12-sender-history-crash-model.md).
-Executable controls live in `tests/message_cli.rs` and the shared schema controls live in
-`crates/fractal-wire/src/message.rs`.

-# Message specification
-
-This document specifies sender-owned native message history. It builds on
-[requirements.md](./requirements.md). Recipient terminal delivery remains in
-[`01-ding/spec.md`](../01-ding/spec.md).
-
-## Status
-
-Active.
-
-The immutable-ID and mutable-address paragraphs are the accepted target. The
-current implementation remains on version 1 and bus-identity routing until
-[DELTA-003](../.delta/DELTA-003-agent-address-not-implemented.md) closes.
-
-## Scope
-
-This specification defines ordinary Agent `message send`, `message reply`, and `message sent`
-publication and observation. It does not project typed service-principal request state, define
-replication guarantees, or reconstruct messages sent before sender-index initialization
-(`MESSAGE-R01`, `MESSAGE-R11`).
-
-## State ownership
-
-```text
-sender resources/sent/                 recipient resources/
-  index.json                             inbox/<filename>.md
-  active.json                            archive/<filename>.md
-  .lock
-  pending/<sha256>.json
-  messages/<filename>.md.json
-  commits/<sha256>.json
-  keys/<sha256>.json
-```
-
-`index.json` is a constant-size atomic head. `active.json` identifies the only publication allowed
-in flight under the sender lock. Pending records own the exact recipient operation. Sender rows own
-the canonical endpoints, filename, metadata, body, optional idempotency key, and exact rendered
-recipient bytes. Immutable content-addressed commit nodes link every completed row to its predecessor.
-Recipient state is never scanned during sent enumeration (`MESSAGE-R01`, `MESSAGE-R02`,
-`MESSAGE-R10`).
-
-The version-1 index is:
-
-```json
-{
-  "version": 1,
-  "since": 1786550000000,
-  "count": 1,
-  "tip": "8b1d..."
-}
-```
-
-A version-1 commit node is:
-
-```json
-{
-  "version": 1,
-  "ordinal": 1,
-  "previous": null,
-  "filename": "1786550000123-abc123.md",
-  "rowDigest": "be42..."
-}
-```
-
-The version-2 Agent record is:
-
-```json
-{
-  "version": 2,
-  "filename": "1786550000123-abc123.md",
-  "ts": 1786550000123,
-  "from": "0199b8f4-8d3a-7c21-9a44-6f85b7320ea1",

-```
-
-Version 1 keeps `from` and `to` as legacy bus identities. Migration freezes
-those same bytes as the legacy agent ID of the subject that kept them, so a
-version-2 reader can interpret old rows without rewriting immutable history.
-An archived collision is the one exception: migration gave that archived
-subject a UUIDv7 while a live subject kept the colliding bytes, so those bytes
-in a version-1 row denote either subject. Migration therefore records every
-reassigned legacy bus identity, the subject that kept it, and the archived
-subject's generated ID as durable collision metadata, and version-2 readers
-consult that metadata instead of universally retyping version-1 endpoints. A
-colliding version-1 endpoint resolves only to the migrated ID of the row's own
-state owner: the sender for a sender-owned row, the recipient for an inbox
-row. Any other colliding endpoint is unattributed: the reader renders
-the legacy bytes as a historical address, never as the keeping subject's ID,
-and refuses reply and automation authority for it rather than addressing the
-live replacement (`MESSAGE-R04`). Version-2 readers accept both versions;
-strict version-1 readers reject version 2. The rollout therefore deploys
-tolerant readers fleet-wide before any version-2 writer activates. Principal
-or external endpoint records use the corresponding `fromKind` or `toKind` and
-keep that endpoint's canonical address in `from` or `to`; agent fields always
-contain agent IDs.
-
-Committed record filenames append `.json` to the canonical message filename. Pending and commit
-filenames are the SHA-256 digest of their canonical JSON content plus `.json`. A pending filename
-therefore binds its content before `active.json` exists. Temporary siblings use the reserved
-`.message.tmp-` prefix and are invisible to readers. A complete read follows exactly `count` nodes
-from `tip` to genesis, verifies
-each content digest, ordinal, predecessor, row digest, and payload/filename relation, then compares
-the exact reachable node and row sets with both directories. Only an active intent may explain an
-otherwise unreachable row or commit node. Missing, extra, substituted, corrupt, unreadable, or
-unsupported-version state fails closed (`MESSAGE-R03`, `MESSAGE-R04`). The atomic head is the bounded
-local trust root; coordinated rewrite of the head and all matching sender state is outside this loss
-and corruption contract (`MESSAGE-A03`).

-## Publication transaction
-
-```text
-per-sender LOCK
-      |
-      v
-head -> pending -> active -> recipient -> row -> immutable node -> head -> cleanup
-          |          |                                           |
-          +----------+------ retry reuses filename and bytes -----+
-```
-
-One advisory kernel lock at `resources/sent/.lock` serializes local publications for that sender.
-The lock file is persistent; dropping the process releases the lock. A send then performs these
-steps (`MESSAGE-R05`, `MESSAGE-R06`, `MESSAGE-R08`):
-
-1. Atomically create `index.json` if absent. Its `since` precedes every indexed send attempt.
-2. Recover the single pending/active publication, if present.
-3. Resolve each ordinary Agent address to one immutable agent ID and capture
-   its current bus address. Persist the IDs as canonical endpoints, the
-   addresses as display-only publication snapshots, and endpoint kind as
-   `agent`. An explicit exact-ID endpoint bypasses address lookup but joins its
-   current address when one exists. A separately admitted principal or external
-   endpoint retains its canonical address with an explicit endpoint kind. An
-   eval external requester at either endpoint bypasses ordinary Sent indexing.
-4. Atomically create one pending record with a fresh canonical message filename.
-5. Atomically create `active.json` containing its filename and record digest.
-6. Materialize the exact recipient bytes under that filename. An identical inbox file or archive
-   receipt is success; different bytes are a collision.
-7. Atomically create the identical sender record under `messages/`.
-8. Create the immutable commit node from the old head and sender-row digest.
-9. Atomically replace the head with the new count and node digest, then publish the scoped immutable
-   idempotency receipt when the caller supplied a key.
-10. Remove the pending record and active pointer, then return the filename.
-
-The directories do not share one transaction. This ordering chooses recipient-only partial state
-over a false completed Sent row (`MESSAGE-T01`). A crash before step 4 has no message effect. A crash
-from steps 4 through 10 leaves enough sender-owned state to resume. A pending record created before
-active publication is an explicit recoverable partial state. An active pointer without pending fails
-unless the head proves that intent already committed. A row or commit node before head publication is
-explained only by the active intent and is not completed Sent. A head-advanced publication with stale
-active or pending state is recoverable cleanup. A pending-only cleanup record must match the current
-head-tip filename, the tip row digest, and the immutable sender row digest. A shared-lock read reports
-that exact record as completed coverage but does not clean it. The next exclusive sender operation
-publishes a missing key receipt and removes the pending record. No recovery mutates an immutable row
-or node. A pending record for an older committed row still fails closed.
-
-## Retry identity
-
-`--idempotency-key` is optional on `send` and `reply`. The durable key scope is
-`(canonical sender agent ID, canonical recipient agent ID, key)`. Under the
-sender lock, a matching completed record returns its original filename.
-Different content under the same scoped key fails. Different recipients may
-reuse a key (`MESSAGE-R07`).
-
-Without a key, pending recovery can reuse the interrupted intent. After the pending record is
-cleared, a crash before stdout creates unavoidable response ambiguity. Repeating identical unkeyed
-input is therefore a new send. Payload hashing is not used because it would collapse intentional
-identical messages (`MESSAGE-T03`, `MESSAGE-R08`).
-
-## Sent API and wire shape
-
-```text
-st2 message sent [address]
-  [--id <agent-id>]
-  [--count]
-  [--include-body]
-  [--since <unix-ms>]
-  [--to <canonical-recipient-id>]
-  [--json]
-```
-
-Selection follows one total order. A positional address selects the subject
-first; otherwise ordinary `--as <address>` selects it; otherwise the command
-uses the exact immutable ID in `ST_AGENT`. `--id` replaces the positional form
-and is mutually exclusive with both a positional address and `--as`. Every
-address form uses ordinary address resolution; neither an address nor
-`ST_AGENT` is heuristically retyped. Rows sort by `(ts, filename)`. `--since`
-is strict; `--to` compares the canonical persisted recipient endpoint.
-`--include-body` adds `body`; otherwise the key is absent. `--count` prints a
-number only for `since` coverage and refuses unavailable or partial coverage
-(`MESSAGE-R03`, `MESSAGE-R09`).
-
-Catalog filesystem read access permits observation of any declared Agent
-selected by current address or explicit immutable ID. Selecting a subject does
-not grant publication authority or change the acting ID. Human output may join
-the current bus address for display. Persisted Agent `from` and `to` fields and
-JSON authority remain immutable endpoint IDs so address changes do not rewrite
-history or break replies. Version-2 nullable `fromAddress` and `toAddress`
-fields preserve publication-time display snapshots without becoming selectors.
-Endpoint-kind fields distinguish non-Agent canonical addresses.
-
-The shared JSON envelope is a tagged coverage union:
-
-```json
-{
-  "coverage": { "_tag": "since", "since": 1786550000000 },
-  "messages": [
-    {
-      "filename": "1786550000123-abc123.md",
-      "ts": 1786550000123,
-      "to": "0199b8f4-8d3a-7c21-9a44-6f85b7320ea1",
-      "subject": null,
-      "inReplyTo": null,
-      "tags": [],
-      "priority": null,
-      "toAddress": "dev3.dotfiles.fractal.keymap.verifier",
-      "toKind": "agent"
-    }
-  ]
-}
-```
-
-Coverage variants are exact:
-
-| `_tag` | Additional fields | Meaning |
-| --- | --- | --- |
-| `unavailable` | none | No index marker exists; empty rows make no historical claim. |
-| `since` | `since` | All successful indexed sends at or after the boundary are represented. |
-| `partial` | `since`, `pending` | The boundary exists, but one or more intents are incomplete. |
-
-`SentMessages`, `SentCoverage`, and `SentMessageRow` live in `fractal-wire`. An
-Agent sent row has canonical `to`, never `from`. Nullable `toAddress` is a
-display-only publication snapshot. Authoritative `toKind` determines whether
-`to` contains an agent ID or a canonical principal/external address; its
-absence on a version-1 row means `agent`. An unrequested body remains absent
-(`MESSAGE-R02`, `MESSAGE-R04`).
-
-### Fractal consumer semantics (non-normative)
-
-For a Fractal Chat projection, `to` is the conversation peer for an outbound row. An empty message
-array with `coverage._tag = "since"` is a complete empty result from that boundary. `unavailable` and
-`partial` require a visible coverage warning and must not be presented as a complete empty history.
-These semantics support a Chat-only projection; they do not claim that ordinary Sent history is a
-generic activity feed or that typed service-principal requests belong in it.
-
-## Typed requests
-
-`request send` and `request reply` retain their service-principal publication records under
-`resources/request-state`. Their stable idempotency and status contract is a lower-level precedent
-for reserving a filename before delivery, but service principals are not Agents and their records do
-not enter ordinary Sent history (`MESSAGE-R11`).
-
-The typed request surface is design-superseded by stream events
-([decision 0004](../.decisions/0004-stream-events-are-a-distinct-record-kind.md)): a reply to an
-event is an ordinary `message reply`, and the `pending | replied` union derives from `in-reply-to`.
-This section stays normative until the staged absorption in
-[04-stream DQ-S4](../04-stream/open-questions.md) completes; the drift is fenced by
-[DELTA-002](../.delta/DELTA-002-typed-request-absorption-pending.md). `MESSAGE-R11`'s separation
-purpose survives the absorption: events remain excluded from ordinary Sent history by never writing
-the sender ledger at all.
-
-## Verification
-
-`tests/message_cli.rs` injects failure after coverage, pending creation, active publication,
-recipient materialization, sender-row creation, commit-node creation, head publication, pending
-cleanup, and active cleanup. It covers payload/filename mismatch; missing, extra, corrupt,
-unreadable, and unsupported-version head/node/row state; digest, predecessor, ordinal, count, and
-genesis mismatch; valid-prefix rollback with an unexplained suffix; idempotency scope; unkeyed
-response loss; symmetric external-eval exclusion; and recipient-independent reads.
-`crates/fractal-wire/src/message.rs` verifies the coverage tags, `to` direction, and body omission.
-
-The catalog performance procedure is defined in the experiment record. It compares Sent with
-same-sender message-ls on one captured catalog and must satisfy both the absolute and relative
-`MESSAGE-R10` gates on the exact candidate commit.
-
-Publication creates a constant number of files and atomically replaces one constant-size head, so
-its history-dependent write work and storage increment are O(1). Complete read validation traverses
-the linked ledger and scans exact sender-owned sets, so it is O(history).

-# Pipes: one actor model, one record family
-
-Date: 2026-08-20
-
-Branch: `schickling/2026-08-20-pipes`
-
-## Question
-
-st2 has three overlapping answers to "who can put a durable item into an agent's inbox":
-
-1. **Ordinary agent messages** (`src/message.rs`) — the sender must be an Agent Spec identity; a
-   sender-owned hash-chained ledger under `resources/sent/`; idempotency scoped
-   `(sender, recipient, key)`; DING renders a relationship glyph.
-2. **Service-principal requests** (`src/request.rs`) — a declared non-agent principal at
-   `principals/<host>/<identity>/principal.kdl`; a *different* durable store under
-   `resources/request-state/`; idempotency scoped `(principal, key)` with the recipient omitted;
-   DING renders `?` and a hardcoded `request <key>` subject.
-3. **Pipe sources** (prototyped, unmerged) — an external event producer supervised as a derived exec
-   companion, with no bus identity of its own at all.
-
-This document takes the unification hypothesis seriously: that all three are one *actor* publishing
-one *record family*, and that the second mechanism exists because of an accident rather than a
-distinction. It then tests that hypothesis against the codebase and reports where it holds.
-
-**Conclusion: unification is the global maximum, and it is a net deletion.** The target model
-removes one durable store, one CLI command group, one identity kind, one wire envelope family, and
-the entire prototyped pipe runner, while adding one actor kind field, one frontmatter key, and one
-DING glyph. The spike proves the seam that decides it.
-
-## Evidence base
-
-Two prototypes on this branch, read in full:
-
-- `2026-08-20-pipes-ingress-prototype.md` — compared the message path and the principal path for
-  external-event ingress. Recommended the principal path on identity and separation grounds, and
-  listed four presentation defects plus one real correctness defect (fan-out collision).
-- `2026-08-20-pipes-lifecycle-prototype.md` — proved `pipe "name" {}` lowers cleanly to a derived
-  exec companion. Its **top recommendation** was: *"Let a declared task identity own a sender
-  ledger… Extending that principal notion to runner-owned task identities would let a pipe be its
-  own sender."*
-
-Both prototypes, from opposite ends, arrived at the same missing piece: **a non-agent producer that
-owns a real sender ledger.** That is the unification, stated as a defect report. This document names
-it as a design and the spike proves it works.
-
----
-
-## 1. The target model
-
-### 1.1 Actors
-
-One concept replaces three. A **bus actor** is a declared identity with a two-component bus id
-`<host>.<identity>` and a home directory owning `resources/{inbox,archive,sent}`. Actors differ only
-by **kind**, which is a property of the declaration site and never of a message:
-
-| Kind | Declared at | Has | Does not have |
-|---|---|---|---|
-| `agent` | `agents/<host>/<identity>/agent.kdl` | persona, tasks, presence, roster row, DING sidecar, doctor obligations, supervisor edges | — |
-| `service` | `principals/<host>/<identity>/principal.kdl` | mailbox, sender ledger, addressability | persona, task, presence, roster row, DING sidecar, doctor obligation, supervisor edge |
-
-There is no third kind. A **pipe source is a `service` actor that declares a command**; a service
-principal is a `service` actor that does not. This is the crux: the differentiation pole needs a
-`pipe` concept *and* a `principal` concept; unification needs one.
-
-`src/actor.rs` in this worktree is the prototype of this table.
-
-**Identity grammar is explicitly two namespaces, and they do not merge.** Bus ids stay
-two-component (`example-linux.gh-ci`). Task ids stay three-component (`example-linux.demo.ding`,
-`example-linux.demo.source-gh-ci`). A task is not an actor and never becomes one — which is precisely why the
-lifecycle prototype's `from = "example-linux.demo.pipe-gh-ci"` failed, and why the fix is to give the source a
-real actor rather than to teach the ledger about task ids.
-
-### 1.2 Declaration surface
-
-The principal declaration grows two optional children and the agent declaration grows nothing:
-
-```kdl
-// today, unchanged: an external producer that calls the CLI itself
-principal "example-ci" host="host-a"
-
-// a supervised event source
-principal "gh-ci" host="example-linux" {
-  serves "demo"                          // lifecycle owner; must be an agent on this host
-  source { command "poll-gh-ci.sh" }     // or: argv "poll" "--json"
-}
-```
-
-`source` requires `serves`. `serves` names the agent whose lifecycle the source is coupled to, and
-lowers to a derived exec task `example-linux.demo.source-gh-ci` — inheriting, unchanged, everything the
-lifecycle prototype measured: restart policy, flapping and parking, suspend/retire teardown,
-crash-loop surfacing, and `st2 tasks --json` reporting. `serves` is *not* the recipient: the source
-addresses whomever it likes, and fan-out works because the key scope includes the recipient.
-
-The runner injects `ST_PRINCIPAL=example-linux.gh-ci` beside the existing `ST_AGENT`, so the source script
-publishes as itself.
-
-**What the source command does is call the ordinary CLI.** This is the largest single deletion in
-the design:
-
-```sh
-st2 message send example-linux.demo \
-  --idempotency-key "$run_id" \
-  --subject "CI $state on PR #42" \
-  -m "$payload"
-```
-
-The lifecycle prototype's `src/pipe.rs` (505 lines), its `st2 pipe run` command, its JSON-line
-protocol, its `summarize` function, and its content-hash dedup fallback all exist *only* because a
-task had no identity and therefore could not be an idempotent sender. Once the source is an actor,
-none of it is needed. The content-hash fallback is worth calling out separately: the prototype proved
-it unsound (`an_id_less_source_dedups_by_content_which_also_collapses_real_repeats`), and this design
-deletes it rather than shipping it — a source that cannot supply an event id passes no
-`--idempotency-key` and gets at-least-once, honestly.
-
-### 1.3 One record family
-
-The inbox record is **already** one family today — a message file with frontmatter, where a typed
-request is distinguished only by `tags: st2-request` and a JSON body. The divergence is entirely on
-the producer side. So unification does not invent a merged record; it deletes the second producer
-store and makes the existing discriminator typed.
-
-Frontmatter gains exactly one key:
-
-```
----
-from: example-linux.gh-ci
-subject: CI failure on PR #42
-kind: event
-idempotency-key: run-7
----
-build job failed
-```
-
-`kind` is one of `message` (default when absent), `request`, `reply`, `event`. `parse_message`
-ignores unknown frontmatter keys (`src/message.rs`, the `_ => {}` arm), so every shipped reader
-tolerates it and every older `st2` binary reads the file correctly, just without the discriminator.
-
-**Note what is *absent* from that frontmatter.** The ingress prototype's spike had to add `source:`
-and `event-id:` fields, because `from:` was forced to name a fake agent and therefore could not name
-the producer. Under unification `from:` *is* the producer and `idempotency-key` *is* the event
-identity, so issue #137's four provenance questions are answered with **zero new provenance fields**:
-
-| #137 asks | Answered by |
-|---|---|
-| which producer emitted it? | `from` — a declared actor, resolvable to a kind |
-| what external event ID caused it? | `idempotency-key` |
-| which message/receipt represents it? | `filename` |
-| newly accepted or deduplicated? | the send receipt's `deduplicated` flag |
-
-### 1.4 One durable producer store
-
-`resources/sent/` — the existing head / active / pending / messages / commits / keys ledger — for
-every actor, with idempotency uniformly scoped `(from, to, key)`.
-
-`resources/request-state/` is **deleted entirely**. Both of its halves are subsumed exactly:
-
-- `request-state/outgoing/<sha256(key)>.json` → `sent/keys/<sha256(to,key)>.json`. This is a strict
-  *improvement*: the request store omits the recipient from the key, which is the fan-out collision
-  the ingress prototype measured (`one_event_fans_out_on_rep1_but_collides_on_rep2`). The unified
-  scope fixes it by construction, per MESSAGE-R07.
-- `request-state/replies/<sha256(reply_to \0 key)>.json` → the same `sent/keys` entry on the
-  replying agent. Today's reply state key is `(agent, principal, key)`; `sent/keys` is
-  `(from, to, key)`. **Identical scope.** The subsumption is exact, not approximate.
-
-`request status` reads `request-state/outgoing` to recover the filename, then scans the principal's
-inbox/archive for a matching reply. Under unification the filename comes from `sent/keys` and the
-reply scan is unchanged.
-
-### 1.5 CLI surface
-
-`request` disappears as a command group; its one genuinely distinct capability is generalized.
-
-| Today | Target |
-|---|---|
-| `request send` | `message send --kind request --idempotency-key …` |
-| `request read` | `message read --json` (the body is the caller's JSON; `kind`, `from`, and `idempotency-key` are structured frontmatter) |
-| `request reply` | `message reply <filename>` — recipient and threading already derive from the inbox item |
-| `request status --idempotency-key` | `message status --idempotency-key … --to …` — now available to **every** actor, so an agent can finally ask "was my keyed message answered?", which it cannot today |
-
-Net: 11 commands in two groups → 8 commands in one group.
-
-### 1.6 DING glyphs
-
-The vocabulary is code-only — there is no glyph table anywhere in `docs/vrs/`, so this amends no
-document. Today: `↺` self, `↓`×n from a supervisor, `↑`×n from a report, `←` from a peer, `?`
-fallback. Target adds `»` for a declared non-agent actor.
-
-This is +1 glyph and it is worth it, because it removes two measured lies and one overload:
-
-```
-today, routed through an agent (ingress Rep 1):   [DING] ← h.pipe-agent: CI failure on PR #42
-today, routed through the owning agent (lifecycle): [DING] ↺ example-linux.demo: pipe gh-ci: {"id":…}
-today, routed through a principal (ingress Rep 2): [DING] ? h.pipe-gh-ci: request github:ci#run-11
-target:                                            [DING] » example-linux.gh-ci: CI failure on PR #42
-```
-
-`?` goes back to meaning only "unknown or unreadable", and the hardcoded `request <key>` subject —
-which `request::publish` bakes into the durable record and which is the only thing DING shows — dies
-with `request send`.
-
-The glyph character itself is a taste decision (see §7).
-
-### 1.7 Deleting the third identity kind
-
-`ExternalInbox` (`src/message.rs`) is a path-based, undeclared identity that exists solely because
-the eval flow needs one non-agent requester mailbox — MESSAGE-A01 calls it "an explicit compatibility
-capability". Under unification the eval flow declares a `service` actor and `ExternalInbox`,
-`resolve_inbox_with_external`, the `external_sender` branch in `send_to_resolved_inbox`, the
-`external: Option<&ExternalInbox>` parameter threaded through five functions, and MESSAGE-A01's
-carve-out all disappear.
-
-This matters for the objective function: unification **narrows** the identity surface from three
-kinds to two. It is the strongest available answer to the "does this become an identity platform?"
-objection.
-
-Call sites are shallow (`src/eval_run.rs:1151`, `src/main.rs:2169`, `src/main.rs:2466`), but the
-spike did not do this work, so it is a proposal with a verified cost estimate, not a proven one.
-
----
-
-## 2. Concept count: today vs target
-
-Counted conservatively. `Flat`/`catalogless` is a recovery compatibility mode, not an identity kind,
-and is excluded from both columns. The "today" column counts what ships plus what the differentiation
-pole would add for pipes, since that is the real comparison.
-
-| Axis | Today (shipped) | Differentiation pole (ships pipes as a third mechanism) | **Target** |
-|---|---|---|---|
-| Identity kinds | 3 (agent, principal, eval external requester) | 3 | **2** (agent, service) |
-| Producer declaration nodes | 1 (`principal`) | 2 (`principal`, `pipe` on agent) | **1** (`principal`, +2 optional children) |
-| Durable producer stores | 2 (`sent/`, `request-state/{outgoing,replies}`) | 2 | **1** (`sent/`) |
-| Idempotency key scopes | 2 (`(from,to,key)`, `(from,key)`) | 2 | **1** (`(from,to,key)`) |
-| Publication transactions in code | 2 (`send_with_ledger`, `publish_once`) | 2 | **1** |
-| Typed request/reply envelope types | 3 (`RequestEnvelope`, `ReplyEnvelope`, `PublicationRecord`) — all with `deny_unknown_fields` | 3 | **0** (the message record carries `kind`) |
-| Message frontmatter keys | 6 (`from`, `subject`, `in-reply-to`, `tags`, `priority`, `idempotency-key`) | 8 (`+source`, `+event-id`) | **7** (`+kind`) |
-| CLI command groups / commands | 2 / 11 | 3 / 12 (`+pipe run`) | **1 / 8** |
-| DING glyphs | 5 | 5 (with two lies and one overload) | **6** |
-| Event-source runner | — | `src/pipe.rs`, 505 lines + JSON-line protocol + content-hash dedup | **0** (the source calls the CLI) |
-| Invariant rows touching publication | 2 | 2 | **1** (merged; see §4) |
-
-Every axis is flat or down against today, and every axis is down against the differentiation pole.
-
----
-
-## 3. Delta from today, by module
-
-| Module | Change |
-|---|---|
-| `src/actor.rs` | **new.** The actor table: `ActorKind`, `Actor`, `resolve_service`, `service_bus_ids`. ~80 lines. |
-| `src/message.rs` | `DeliveryEndpoint::Service` variant; service branch in `resolve_delivery_endpoint`, in the sender resolution inside `send_to_resolved_inbox`, and in `with_resolved_state_dir`. **Also required and not done in the spike:** the same branch in `resolve_list_box` and `archive_resolved_message`, without which `message ls`/`read`/`archive` cannot reach a service actor's mailbox (§5). Later: delete `ExternalInbox` and the `external` parameter from five signatures; add `kind` to `Message`, `SentRecord`, and the frontmatter renderer/parser. |
-| `src/request.rs` | **deleted.** `publish_once`, `record_path`, `atomic_create`, `RequestEnvelope`, `ReplyEnvelope`, `PublicationRecord`, and the hardcoded subject all go. `discover_principals` and `ServicePrincipal` (~100 lines) relocate to `src/actor.rs`; the remaining ~400 lines are deleted outright. |
-| `src/ding/mod.rs` | `RelationshipResolver` gains `services`; `relationship_marker` gains the `»` branch *after* the fail-closed validity check. |
-| `src/main.rs` | `RequestCmd` deleted; `MessageCmd::Status` added; `--kind` on send. |
-| `crates/fractal-wire/src/message.rs` | `MessageRow.kind` / `SentMessageRow.kind`, optional, no `deny_unknown_fields` (unchanged policy). |
-| `crates/agent-spec/src/spec.rs`, `kdl_format.rs`, `declared.rs` | `serves` + `source` on the principal declaration; source-task synthesis. No `pipe` node on the agent. |
-| `src/reconcile.rs` | Extend the "unsupported derived task" gate to source companions — one arm, exactly as the lifecycle prototype measured. |
-| `src/eval_run.rs` | Declare a service actor instead of provisioning an `ExternalInbox`. |

-## 4. Requirements and invariants: survives, re-expressed, or amended
-
-### Survives unchanged
-
-- **MESSAGE-R01/R02/R03/R04/R05/R06/R08/R09/R10** — the ledger transaction, recipient-first
-  ordering, coverage honesty, shared wire, resumable intent, serialized writes, directional filters,
-  and the catalog-scale read are all untouched. The spike exercises R05/R06 for a non-agent sender at
-  every checkpoint.
-- **MESSAGE-R07 exact keyed retry** — *strengthened by extension.* The `(sender, recipient, key)`
-  scope now governs every actor, which is exactly what removes the request path's fan-out collision.
-- **Exactly-once-safe native bus** — filename grammar and archive receipts untouched.
-- **Fail-closed observed native DING** — the new glyph is unreachable while
-  `!resolver.valid`, proven by a dedicated test (§5).
-- **Derived companion lifecycle** — a source companion is a derived task; the lifecycle prototype
-  proved the seam is keyed on `Task::derived`, not on the name `ding`.
-- **Runner-owned task identity** — unchanged; `ST_PRINCIPAL` is additive and does not touch
-  `ST_AGENT`.
-- **R19, R23, R24** — stable identity, targeted reconciliation, and the task inventory wire shape are
-  untouched. The lifecycle prototype already proved a derived source task reports honestly through
-  `st2 tasks --json` with no schema change.
-
-### Re-expressed (same purpose, different mechanism)
-
-- **MESSAGE-R11 typed-request separation.** Today: "request publication state does not appear in
-  ordinary Agent Sent history", enforced by *keeping a separate store*. Target: enforced by a *kind
-  projection* over one store — `message sent` defaults to `--kind message`.
-
-  This is the amendment that most deserves scrutiny, so state its purpose plainly: R11 exists so that
-  Sent is an honest record of an agent's conversations rather than a machine activity feed. A
-  kind-filtered projection preserves that purpose exactly while deleting a store. What it gives up is
-  *structural* enforcement — today an agent physically cannot see request state in Sent; tomorrow it
-  is a default filter. Mitigation: `kind` is typed frontmatter set by the publisher at render time
-  and carried into the immutable `SentRecord`, so it cannot be retro-edited without failing the
-  row-digest check. The proposed R11 text:
-
-  > **MESSAGE-R11 Typed-record separation:** `message sent` enumerates only rows whose kind is
-  > `message` unless a kind filter selects otherwise. Request, reply, and event rows remain
-  > sender-owned and durable but are not ordinary Agent Sent history.
-
-- **MESSAGE-A01 declared senders.** The eval external-requester carve-out is deleted; the assumption
-  becomes "a catalog-backed sender is a declared actor", which is a *narrower* statement than today's
-  because it removes the undeclared path-based identity.
-
-- **Idempotent service requests** (INVARIANTS row). Merges into the message row. The four named
-  proofs in `tests/request_cli.rs` are the guarantee's current evidence, and
-  `tests/invariants.rs::qualified_proof_references_resolve` fails if they are deleted without
-  replacement. The migration order is therefore fixed: land equivalent proofs on the unified path,
-  edit the row to name them, **then** delete `request.rs`. The spike keeps all four green (§5).
-
-### Deliberately amended
-
-- **R10 Agent-only identity** — verbatim: *"st2 models agents. Non-agent identities are
-  unsupported."*
-
-  This requirement's letter is **already violated by shipped code**: `docs/vrs/spec.md` §"Service-principal
-  request transport" declares `principals/<host>/<identity>/principal.kdl` and `st2 request send`
-  ships today. R10 has not been reconciled with it. Unification does not widen the breach — it
-  reduces the number of non-agent identity kinds from three to two and makes the remaining one
-  declared, catalog-visible, and validated. Proposed text:
-
-  > **R10 Declared-actor identity:** st2 models agents. Every other bus participant is a declared
-  > non-agent actor with a catalog declaration, a bus id, and a mailbox, and with no persona, task,
-  > presence, roster, delivery-transport, or supervisory authority. Undeclared identities are
-  > unsupported.
-
-- **Vision, "What This Is Not"** — verbatim: *"A general messaging or identity platform for people,
-  services, or arbitrary non-agent actors while the agent and st2 specs are still stabilizing."*
-
-  The carve-out holds without amendment, and the operative word is **arbitrary**. A service actor is
-  not arbitrary: it requires a catalog declaration whose content must exactly match its path, it
-  cannot collide with an Agent Spec identity, it acquires no authority over any agent, and it cannot
-  claim a delivery transport. The vision clause excludes an *open* identity platform; the target
-  model is a *closed, declared* two-kind table. If anything the spirit is better served after the
-  change, because the undeclared `ExternalInbox` path — which genuinely is an ad-hoc identity — is
-  the thing being deleted.
-
-### New ontology terms
-
-`docs/vrs/ontology.md` has no entry for `principal`, `request`, or `inbox` today (its rule is that
-terms without an independent authority are deliberately absent). The target adds two with real
-authorities: **bus actor** (`src/actor.rs::Actor`) and **actor kind** (`src/actor.rs::ActorKind`), and
-retires the term "service principal" in favour of "service actor". Cost: +2 ontology entries.
-
----
-
-## 5. The spike
-
-### What was chosen and why
-
-The riskiest seam is **whether a non-agent actor can own the real durable sender ledger**. If it
-cannot, `request-state` must survive, the fan-out defect stays, pipes need a third mechanism, and the
-whole design collapses into a rename. Everything else in the design is presentation, naming, or
-mechanical deletion.
-
-The advisor's sharpening was decisive here: both prototypes proved *concurrent replay* for their own
-sender, but **neither proved crash recovery for a non-agent sender**. The principal path gets its
-crash safety from a pre-reserved filename — a completely different mechanism — so its evidence says
-nothing about whether the ledger transaction works when the actor is not an agent. And
-`recover_active` re-resolves the recipient endpoint mid-recovery, so the recovery path exercises the
-actor table independently of the happy path. That is the discriminating question.
-
-### The feasibility signal
-
-`send_with_ledger` is already generic over `sender_root: &Path` and `from: &str`. The entire agent
-coupling lives one layer up, in resolution. This predicted the spike would succeed, and it did.
-
-### Code
-
-| Change | Where |
-|---|---|
-| The actor table | `src/actor.rs` (new, ~140 lines with tests) |
-| `DeliveryEndpoint::Service`; service branches in `resolve_delivery_endpoint`, sender resolution, `with_resolved_state_dir` | `src/message.rs` |
-| `»` marker, `services` on the resolver, fail-closed ordering | `src/ding/mod.rs` |
-| E2E evidence | `tests/actor_unification.rs` (new, 6 tests) |
-| Marker evidence | `src/ding/mod.rs::tests` (2 tests) |
-| Actor-table evidence | `src/actor.rs::tests` (4 tests) |
-
-`request.rs` was **not** deleted in the spike. The point was to prove the seam, not to perform the
-migration; leaving it in place also proves the two paths coexist, which is what the migration
-requires (§6).
-
-### Results — 13 tests, all green
-
-**The discriminator.** `tests/actor_unification.rs::a_service_actor_recovers_from_a_crash_at_every_publication_checkpoint`
-injects a failure after each of the nine publication checkpoints (`coverage`, `pending`, `active`,
-`recipient`, `row`, `node`, `head`, `pending-cleanup`, `active-cleanup`) with a non-agent sender, then
-retries. For every checkpoint: exactly one durable inbox item, the retry reports the delivered
-filename, a third replay adds nothing, and `message sent` reports complete `since` coverage rather
-than `partial`. **A non-agent actor owns the ledger with full crash-recovery semantics.**
-
-**The seam.** `a_service_actor_owns_the_same_durable_sender_ledger_as_an_agent` — a principal's send
-creates `principals/h/gh-ci/resources/sent/{index.json,messages,commits,keys}` and creates **no**
-`request-state` directory; `message sent h.gh-ci --json` returns `coverage._tag = "since"` with the
-row's `to`, `subject`, and `idempotencyKey`.
-
-**The measured defect, fixed.** `one_event_key_fans_out_to_two_agents_instead_of_colliding` — one
-key, two recipients, two messages, two sender rows. This is the exact case the ingress prototype
-recorded as `Error: idempotency key reused with different request`. Conflicting reuse of one scoped
-key still fails per recipient.
-
-**The reply channel, for free.** `an_agent_replies_to_a_service_actor_over_the_ordinary_message_path`
-— `message reply` reaches the service actor's inbox and produces an ordinary sender-owned row with
-`to = h.gh-ci`. No typed envelope, no `request reply`.
-
-**Additivity.** `an_agent_identity_still_wins_over_an_identically_named_service_actor` (agents win
-every ambiguity, so no shipped address can be re-pointed) and `an_undeclared_sender_is_still_refused`
-(publication authority unchanged).
-
-**DING.** `src/ding/tests.rs::a_declared_service_actor_renders_its_own_marker_rather_than_unknown`
-renders `[DING] » h.gh-ci: CI failure on PR #42 [id:abc123]` while an undeclared sender still renders
-`?`. `an_invalid_catalog_cannot_promote_a_service_sender_out_of_unknown` is the fail-closed gate: a
-broken declaration anywhere in the catalog forces `?` even for a genuinely declared service actor, so
-the new glyph cannot be reached on a guess.
-
-**Actor table.** `src/actor.rs::tests` — resolution by bus id and by local bare identity agree; a bare
-identity does not reach another host's actor; a malformed `principals/` tree yields *no* actors rather
-than a partial table; an absent tree is simply empty.
-
-### Regression status
-
-Green after the change: `--test actor_unification` (6), `--test message` (6), `--test message_cli`
-(17), `--test request_cli` (9), `--test invariants` (1), `--lib` (see §8).
-
-All four `tests/request_cli.rs` proofs named in the "Idempotent service requests" invariant row are
-green, and `tests/invariants.rs::qualified_proof_references_resolve` passes.
-
-### What the spike did NOT prove
-
-Stated so the design is not credited with coverage it lacks:
-
-- **The read path is only half extended, and this is measured, not assumed.**
-  `the_service_actor_read_path_boundary_is_exactly_where_resolution_was_extended` pins it: `message
-  sent` reaches a service actor (via `with_resolved_state_dir`), while `message ls` and `message
-  read` still fail with `no agent 'h.gh-ci' found in catalog` because `resolve_list_box` and
-  `archive_resolved_message` were not extended. Delivery, publication, and recovery — the parts the
-  design's central claim rests on — are unaffected; a service actor's mailbox is simply not yet
-  readable through the ordinary list commands. The test asserts the *current* failure, so it turns
-  red the moment the real implementation closes the gap.
-- `request.rs` deletion and the `request-state` → `sent/keys` subsumption. Argued exactly in §1.4;
-  not executed.
-- `ExternalInbox` deletion and the eval-flow refactor.
-- The `kind` frontmatter key and the R11 projection.
-- `serves` / `source` KDL lowering and source-task synthesis. The lifecycle prototype proved the
-  derived-companion seam for a `pipe` node; the same seam under a different declaration site is very
-  likely but unproven.
-- `message status`.
-- High-volume ledger behavior (§7).
-
----
-
-## 6. Migration and compatibility
-
-### The constraint that decides the shape
-
-`src/request.rs` puts `deny_unknown_fields` on all three of `RequestEnvelope`, `ReplyEnvelope`, and
-`PublicationRecord` (lines 41, 53, 64), and every one of `request read`/`reply`/`status` parses
-through them. So a new field in the request envelope is a **hard parse failure** in an older binary,
-not a tolerated addition. In-place evolution of the request wire is therefore not available.
-
-The message wire is the opposite: `crates/fractal-wire` documents that no type uses
-`deny_unknown_fields`, and `parse_message` ignores unknown frontmatter keys outright. Adding `kind`
-is safe in both directions.
-
-This settles the migration on the house pattern of fresh namespaces over in-place migration.
-
-### Migration plan
-
-1. **Land `src/actor.rs` and the service-sender seam.** Purely additive — agents win every ambiguity,
-   so no existing address changes. This is what the spike already does, and it is independently
-   shippable.
-2. **Land `kind` frontmatter and the R11 projection.** Old readers ignore it; `message sent` behavior
-   is unchanged for agents because absent `kind` defaults to `message`.
-3. **Land `message status` and equivalent proofs for the four request invariants on the unified
-   path.** Edit the INVARIANTS row to name the new proofs. `qualified_proof_references_resolve` makes
-   this order mandatory.
-4. **Deprecate `request send/read/reply/status`.** They keep working against `request-state`.
-5. **Delete `request.rs` and `request-state`.**
-
-### What happens to existing state
-
-- **Existing catalogs**: unchanged. `agents/` and `principals/` keep their paths and their content
-  rules; `principal.kdl` gains only optional children.
-- **Existing messages**: unchanged on disk. Every inbox item without `kind` reads as
-  `kind: message`, which is what it is.
-- **Existing sender ledgers**: unchanged. `sent/` gains no new files; `SentRecord` gains one optional
-  field, and old rows without it deserialize with `kind = message`.
-- **Existing `request-state` records**: **not migrated.** They are producer-side dedup receipts, and
-  the honest consequence is that a request published under the old path and replayed after the
-  cutover would publish once more. Mitigation: step 4's deprecation window is where a producer
-  re-keys, and the receipts are already unpruned garbage today (the ingress prototype's open question
-  #4: "nothing prunes them today"). Deleting the directory at cutover is correct and should be stated
-  in the release note rather than papered over with a converter.
-- **In-flight typed requests** across the step-5 boundary lose their `request status` channel. The
-  deprecation window in step 4 exists for exactly this.
-
-### Verdict
-
-Compatible for readers and for on-disk message state at every step; a deliberate, announced
-one-time loss of producer-side request dedup receipts at the final cutover, with a deprecation window
-to drain them.
-
----
-
-## 7. Costs and risks
-
-1. **One ledger shape for wildly different volumes.** Every actor gets the full hash-chained coverage
-   ledger. A CI poller emitting 100k events accumulates a Merkle chain nobody reads, and `message
-   sent` on that actor is O(history). Writes stay O(1) and MESSAGE-R10's p95 gate is about catalog
-   scale (557 agents, one sender row), not history depth — so the gate is not threatened, but the
-   storage is real.
-
-   **This is the strongest honest objection and it must not be soft-pedalled.** The alternative — a
-   `keys/`-only ledger profile for service actors — would be a kind-dependent store shape, which
-   quietly re-splits the store this design exists to merge. The position taken here is: one shape,
-   and unbounded growth becomes *one* retention problem instead of two. It is worth noting that
-   `request-state` has the identical unbounded-growth problem today and nothing prunes it either, so
-   unification does not add the problem; it makes there be one place to fix it. If measurement later
-   shows a high-rate source is untenable, the honest fix is a retention rule on `sent/`, not a second
-   store.
-
-2. **R11 loses structural enforcement.** Discussed in §4. A default filter is weaker than a separate
-   directory. The mitigation (typed frontmatter carried into the digest-protected immutable row) is
-   real but is not the same guarantee.
-
-3. **Declaration locality.** `serves "demo"` puts a source's existence in `principals/` rather than in
-   the agent's own declaration, so reading `agent.kdl` no longer tells you everything attached to that
-   agent. The lifecycle prototype's `pipe` node had better locality. Recoverable via `st2 tasks
-   --json` and `st2 agents`, but it is a genuine ergonomic loss and a reasonable person could go the
-   other way.
-
-4. **`request status`'s reply correlation is thinner than it looks.** `status` scans the principal's
-   inbox and archive for a matching reply. Generalizing it to `message status` for every actor means
-   that scan runs on agent-sized mailboxes. Bounded by the mailbox, not by history, but unmeasured.
-
-5. **`+1` DING glyph is a string every agent sees.** Changing the notice vocabulary is a fleet-wide
-   behavior change even though no VRS document specifies it.
-
-6. **The `serves` requirement is a real restriction.** A source with no owning agent has no lifecycle
-   owner and is refused. That is the right v1 answer — a second lifecycle owner is exactly what the
-   lifecycle prototype argued against — but it means a fan-out-only source must nominate an arbitrary
-   agent as its supervisor, which is slightly dishonest.
-
-7. **Two rules for one question, in the spike and to be avoided in the implementation.** The `»`
-   branch in `relationship_marker` matches a local bare identity by string surgery
-   (`strip_prefix(this_host)` then `strip_prefix('.')`), while `actor::resolve_service` matches on
-   `principal.host == this_host && principal.identity == id`. They agree today, but the DING marker
-   and the delivery path can drift apart. In the target model the marker must call the actor table
-   rather than re-derive it — the whole point of having one table. Likewise, the service arm of
-   `with_resolved_state_dir` ignores the `create` parameter the agent arm honors via
-   `open_message_box`; harmless for the spike's callers, and not to be inherited silently.
-
-8. **Scope.** This is a refactor across `message.rs`, `request.rs`, `ding/mod.rs`, `main.rs`,
-   `eval_run.rs`, `agent-spec`, and `reconcile.rs`, touching two INVARIANTS rows. The staging in §6
-   makes each step independently shippable and reversible, but the total is much larger than "add a
-   `pipe` node".
-
----
-
-## 8. Steelman for the opposite pole
-
-The differentiation argument deserves its strongest form, because it is not weak.
-
-`request.rs` has its own tiny `publish_once` **for a reason**: a CI poller needs a reserved filename
-and nothing else. It does not need a hash chain, a coverage tag, a per-sender flock, or the concept
-of "complete sender history". The ledger is 400 lines of machinery serving a requirement — *an agent
-must be able to prove what it sent* — that no machine producer has. Unification does not delete that
-machinery; it **imposes** it on every producer, and then §7.1 has to argue away the consequences.
-
-Meanwhile, the shipped principal path already satisfies both boundaries the ingress prototype cared
-about (R10 and MESSAGE-R11), and its defects are four small, local fixes: add `--subject`, add a
-marker glyph, add `to` to the receipt, and put the recipient in the state key. That is perhaps 100
-lines against a multi-module refactor that amends R10, re-expresses MESSAGE-R11, and merges two
-INVARIANTS rows. On a pure cost-to-fix-the-known-defects basis, differentiation wins outright.
-
-**Why I still recommend unification.** Two reasons the differentiated path cannot answer:
-
-- Fixing the state key to `(principal, recipient, key)` is not a small fix — it is
-  *re-deriving MESSAGE-R07 in a second place*. The second mechanism does not stay small; it converges
-  on the first one defect by defect. The four "small local fixes" are each a step of that
-  convergence, and the endpoint of that process is two implementations of the same thing.
-- The lifecycle prototype's top recommendation is unreachable from the differentiated pole. A pipe
-  source needs a sender ledger *and* recipient-scoped idempotency *and* an honest `from`. Give
-  `request-state` all three and it **is** `sent/`. Differentiation ships a third mechanism (`pipe`
-  node, `pipe run`, JSON-line protocol, content-hash dedup) to avoid admitting that.
-
-The objective function was "a design that deletes two mechanisms and adds one is winning; a design
-that adds a clean-looking third while the old two survive is losing." Differentiation is, by
-construction, the second one.
-
----
-
-## 9. Decisions that remain genuinely human
-
-Not derivable — taste, policy, or product:
-
-1. **The glyph.** `»` is a proposal. It is a string every agent in the fleet reads.
-2. **Declaration locality (§7.3).** `principal { serves }` versus `agent { source }`. Both work; the
-   tradeoff is single-source-of-truth for identity versus locality when reading an agent.
-3. **Does R11's purpose survive a default filter?** §4 argues yes. This is a judgment about what
-   "honest Sent history" means, and it is Johannes's and Alex's call, not a derivation.
-4. **Is one ledger shape acceptable for a high-rate source (§7.1)?** The alternative re-splits the
-   store. This is the one place where the design's central claim could be traded away for
-   performance, and it should be traded knowingly or not at all.
-5. **Do pipe events belong in the agent's ordinary inbox?** Unchanged from both prototypes' open
-   questions. A busy CI source changes how an inbox feels, and #238's bounded-body delivery makes the
-   budget question sharper.
-6. **What happens to events while an agent is suspended?** The source is torn down with its agent, so
-   events during suspension are not observed. Correct for a live CI feed, wrong for an audit trail.
-7. **Is a source-supplied event id mandatory?** This design makes it *optional and honest*: no key
-   means at-least-once, rather than the prototype's unsound content-hash dedup. Refusing such a source
-   outright is safer and more annoying.

-## VRS Impact
-
-None yet. This is a spike record. It carries no requirement, no ontology term, and no INVARIANTS
-entry. It is evidence for DQ1's KDL-shape, event-inbox, deduplication-boundary, and
-execution-receipt items, and it proposes — but does not land — amendments to R10, MESSAGE-A01, and
-MESSAGE-R11 that a human must accept before any of them are written down.
-
-## Method
-
-Design exploration from the unification pole with an executable spike of the
-riskiest seam: §1–§4 derive the target model and its delta from the code and
-VRS on `main` (8ff140e); §5 documents the spike (a service actor owning the
-durable sender ledger, crash injection at every publication checkpoint,
-fan-out, DING marker rendering), run as 13 tests in the exploration worktree.
-
-## Result
-
-See §2 for the concept-count table and §5 for the spike outcomes: 13 tests
-green, crash recovery proven at all nine publication checkpoints for a
-non-agent sender, fan-out fixed by construction, `»` marker rendered with a
-fail-closed gate; one self-claim disproved (`message ls`/`read` for service
-actors remains unextended). Full-workspace failure set identical to baseline.
-
-## Conclusion
-
-Unification is safe and flattens every concept axis, but it imposes the
-sender ledger's prove-what-I-said machinery on machine producers; §8's
-steelman concedes the misfit for high-volume sources. Decision 0004 selected
-the differentiation pole's record model while adopting this exploration's
-identity convergence and fan-out fix.

-# Pipes: a first-class event model (differentiation pole)
-
-Date: 2026-08-20
-
-Branch: `worktree-agent-ae190cd91778e7149`, based on `8ff140e` (the tip of
-`schickling/2026-08-20-pipes`, which is held by another worktree)
-
-## Question
-
-Who or what may put a durable item into an agent's inbox, and how is the producer
-identified across the whole system?
-
-This document starts from the hypothesis that **conversational messages and
-world-events are genuinely different concepts** and that the global maximum keeps
-them distinct. It tests that hypothesis against the two prototype spikes, the
-shipped code, and the sacred invariant set, and reports where the split earns its
-keep and where it does not.
-
-Companion explorations: the ingress prototype
-(`.../agent-ae38fe3de554a4a01/docs/vrs/.experiments/2026-08-20-pipes-ingress-prototype.md`)
-and the lifecycle prototype
-(`.../agent-a540e72fcb3229f96/docs/vrs/.experiments/2026-08-20-pipes-lifecycle-prototype.md`).
-This is the differentiation-pole design; a unification-pole design was explored
-independently.
-
-## Summary of the verdict
-
-The differentiation hypothesis survives on two axes and loses decisively on four.
-The recommended model **differentiates the record kind and the producer identity**
-— stream identity, supersession, bounded retention, a distinct notice — and
-**unifies the transport, the storage location, the read commands, and the reply
-path**. The pure differentiation design, with events in their own durable store
-behind their own DING notice path, is measured and rejected in §7.
-
-Concretely:
-
-- keeps ordinary agent↔agent messages **completely untouched**;
-- collapses today's five producer identity kinds into **two** — *agent* and
-  *source*;
-- makes an **event** a distinct record kind carried in the ordinary inbox, with
-  `(from, stream, event-id)` identity, producer-side supersession, and *bounded*
-  dedup retention that ordinary messages deliberately do not have;
-- **absorbs service-principal requests into the event model**, deleting the typed
-  request/reply envelope pair, `request-state/replies/`, and two CLI commands;
-- gives events their own DING glyph, so `?` stops doubling as "legitimate machine
-  producer" and goes back to meaning only "st2 could not resolve this".
-
-A "pure" differentiation design — events in their own durable store with their own
-DING notice path — was evaluated and rejected on measured cost. See
-[Rejected: a separate event store](#7-rejected-a-separate-event-store).
-
----
-
-## 1. What exists today
-
-### 1.1 Five things can already write an agent's inbox
-
-R10 says "st2 models agents. Non-agent identities are unsupported." That
-requirement is already carved out five ways in shipped code:
-
-| # | Producer identity | Where | Ledger | DING glyph |
-|---|---|---|---|---|
-| 1 | Agent Spec bus id | `message::send_to_resolved_inbox` | `resources/sent/` (9 file kinds) | `↺ ↓ ↑ ←` |
-| 2 | Service principal | `request::publish`, `principals/<host>/<id>/principal.kdl` | `resources/request-state/outgoing/` | `?` |
-| 3 | Eval external requester | `message::ExternalInbox` (MESSAGE-A01 compat) | none | `?` |
-| 4 | The runner, as `st2.<host>` | `src/run.rs:2107` `surface_crash_loop` → `send_to_inbox` | none | `?` |
-| 5 | The literal string `st2` | `src/eval_run.rs:1031` → `send_to_inbox` | none | `?` |
-
-The pipe prototypes add a sixth attempt and both fail on it:
-
-- The **lifecycle prototype** could not give a runner-owned task identity a sender
-  ledger, so a pipe sends *as its owning agent* and the agent reads
-  `[DING] ↺ example-linux.demo: pipe gh-ci: …` — an external CI event presented as the
-  agent talking to itself. Its own top recommendation (f)(1) is to fix exactly
-  this.
-- The **ingress prototype** proved the message path *cannot* express a non-agent
-  producer at all (`rep1_refuses_a_non_agent_sender_but_rep2_accepts_a_declared_principal`)
-  and that forcing one into an Agent Spec buys a roster row, a presence record, a
-  derived DING sidecar, and doctor health obligations that a CI poller never
-  wanted.
-
-So the honest framing of R10 is not whether to introduce a non-agent identity —
-st2 already has four of them, three undeclared and unattributed. The design
-question is **how few** identity kinds the system can have.
-
-### 1.2 Requests are already an event plus a message thread
-
-`src/request.rs:346 status()` is the sharpest single piece of evidence in this
-document. Its implementation of the "typed reply channel" is:
-
-```rust
-for directory in [principal.inbox(), principal.archive()] {
-    for candidate in message::list_dir(&directory)? {
-        if candidate.in_reply_to.as_deref() != Some(record.filename.as_str()) { continue; }
-        …
-    }
-}
-```
-
-That is a **thread scan for an ordinary message reply**, wrapped in JSON-envelope
-validation. The `ReplyEnvelope`, the `st2-request-reply` tag, and
-`request-state/replies/` exist only to re-derive facts that `in-reply-to` and
-`from` already carry on the message file. The typed layer is not buying
-routing — it is buying schema validation on a body, which the producer could do
-itself.
-
-Its measured costs are real:
-
-- `request::publish` hardcodes `Some(&format!("request {idempotency_key}"))` as
-  the subject, and the subject is the only thing DING shows. The ingress
-  prototype's poller run produced four consecutive notices that say nothing:
-  `[DING] ? h.pipe-gh-ci: request github:ci:pr-42#pending`.
-- The body is an opaque JSON envelope, so `message read` / `message thread` are
-  useless on it.
-- The state key omits the recipient, so **one event cannot fan out to two
-  agents** (`one_event_fans_out_on_rep1_but_collides_on_rep2`).
-- Agents must know two reply verbs (`message reply`, `request reply`) and pick by
-  inspecting the sender.
-
-### 1.3 What the prototypes settled empirically
-
-Treated as given, not relitigated:
-
-- Delivery must ride the existing inbox → DING/MCP/app-server transports.
-- Producer-side supersede is the only viable coalescing point: `flush_pending`
-  sees one notice at a time and holds exactly one staged payload, and DING
-  deliberately never deletes inbox items
-  (`producer_side_supersede_collapses_a_stream_to_its_latest_event`).
-- A source-supplied event id is the dedup contract; content hashing cannot
-  distinguish replay from a legitimate repeat
-  (`an_id_less_source_dedups_by_content_which_also_collapses_real_repeats`).
-- Derived-companion lifecycle is generic over `Task::derived` and needed only a
-  two-line gate extension to carry a new companion kind.
-

-
-## 2. Target model
-
-### 2.1 Two identity kinds
-
-**Agent** — unchanged. A full Agent Spec: persona, tasks, presence, roster row,
-derived DING, doctor obligations, sender-owned Sent ledger.
-
-**Source** — a declared non-agent producer of world-events. It has a bus id, a
-state folder, and an inbox (so an agent can reply to it). It has **no** persona,
-presence record, roster row, derived DING, supervisor edge, or Sent ledger.
-
-```kdl
-// sources/example-linux/gh-ci/source.kdl
-source "gh-ci" {
-  host "example-linux"
-  command "poll-gh-ci --json"        // optional
-  restart { attempts 5 mode "delay" }
-  desired-state "running"
-}
-```
-
-The `command` is what unifies today's two shapes:
-
-| `command` | Meaning | Replaces |
-|---|---|---|
-| absent | An endpoint only. Some external thing (systemd timer, webhook receiver, an eval harness) emits into it. No task, no supervision. | `principals/<host>/<id>/principal.kdl` |
-| present | st2 supervises one long-running exec task `<host>.<name>` whose stdout is events. | the lifecycle prototype's `pipe "name" { … }` |
-
-This is the load-bearing simplification. The lifecycle prototype's two sharpest
-frictions both disappear:
-
-- *"A task identity cannot be an idempotent bus sender."* A source's task **is**
-  the source, so `ST_AGENT`-style runner identity and sender identity coincide.
-  No impersonation, no `↺`, no `x-st2-pipe-task:` body line.
-- *"The derived marker carries no payload."* A source's command is an ordinary
-  authored task command. No marker-argv smuggling, no `pipe_name_of_task`, no
-  invented task-name grammar, no `pipe-launch-missing` /
-  `unsupported-pipe-interval` diagnostics, no `pipe`-vs-`exec` name-collision
-  check.
-
-**Why top-level rather than nested on an agent.** Fan-out alone does not decide
-this: the ingress prototype's fan-out defect is *ledger scoping*, not declaration
-placement, so a nested pipe that scopes its ledger by `(stream, event-id,
-recipient)` can also feed several agents from one process. Three other things
-decide it:
-
-1. **Teardown coupling.** A nested pipe is a derived companion, and the *Derived
-   companion lifecycle* invariant stops a companion whenever its agent is held,
-   suspended, retired, or parked. Suspending agent A would therefore silently stop
-   the CI feed that agents B and C depend on. That is a correctness bug, not an
-   aesthetic one, and it appears the moment a source has more than one consumer.
-2. **Arbitrary ownership.** A shared GitHub poller has no natural owning agent, so
-   nesting picks one by accident and encodes it in the runtime id.
-3. **It absorbs `principal`.** A nested pipe cannot be the same concept as
-   `principals/<host>/<id>/principal.kdl`, which is inherently top-level, so the
-   nested shape leaves the system with two declaration kinds for non-agent
-   producers instead of one. The `command`-present/`command`-absent split is what
-   collapses them, and it only works at top level.
-
-The cost is real and is stated in §10: a top-level source is the one part of this
-design that needs new reconciler work.
-
-**Reserved sources.** `st2.<host>` becomes a *built-in* source identity — the
-runner's crash-loop notice (`src/run.rs:2107`) and the eval harness notices
-(`src/eval_run.rs:1031`, `:1471`) stop being unattributed strings and become
-events from a declared reserved source. The eval external requester
-(`ExternalInbox`) is a source whose `command` is absent and whose inbox is the
-reply target: exactly the shape it already has, given a name.
-
-### 2.2 Event identity: a three-part grammar
-
-```
-from       example-linux.gh-ci            who produced it (a source bus id)
-stream     github:ci:pr-42       which series of facts this belongs to
-event-id   failure               which occurrence within that series
-```
-
-`(from, stream, event-id)` is the event's identity. The dedup ledger is scoped
-by `(stream, event-id, recipient)` within one source, matching MESSAGE-R07's
-`(sender, recipient, key)` scoping — which is what makes fan-out work and what
-today's `request-state` gets wrong.
-
-This grammar resolves an ambiguity in issue #137, which uses `--source` for what
-is really the *stream* (`systemd:dev3-janitor-daily`) while the producer identity
-stayed implicit. Splitting them means `from` is a declared, resolvable identity
-the DING glyph can reason about, and `stream` is a free-form producer namespace
-st2 never interprets — the same discipline R20 applies to Resource URIs.
-
-### 2.3 The record on disk
-
-An event is an ordinary message file in the recipient's `resources/inbox/`, with
-the ordinary `<unix-ms>-<rand6>.md` grammar and the ordinary archive receipt.
-Two new frontmatter keys:
-
-```
----
-from: example-linux.gh-ci
-subject: CI failed on PR #42
-stream: github:ci:pr-42
-event-id: failure
----
-build job `test` failed on commit 9ca9a2a
-```
-
-There is deliberately **no** `kind: event` discriminant. An inbox item is an
-event exactly when its `from` resolves to a declared source; `stream:` and
-`event-id:` are its stream coordinates. Producer kind and record kind are the
-same fact, and duplicating it would create a way for them to disagree.
-
-`src/message.rs:242 parse_message` ignores unknown frontmatter keys
-(`_ => {}`), and `crates/fractal-wire` has no `deny_unknown_fields`, so both
-directions of version skew are safe by construction — an older reader sees an
-ordinary message with an unusual sender, and an older st2 binary reading a
-newer file loses only the stream coordinates.
-
-The body is whatever the producer wrote: markdown for a legible event, JSON for
-a typed one. Typing moves from a mandatory st2 envelope to a producer choice,
-which is what makes `message read`, `message ls --include-body` (#238), and
-`message thread` work on events for free.
-
-### 2.4 The durable event store: one file per (stream, recipient)
-
-```text
-sources/<host>/<name>/resources/
-  inbox/<filename>.md            replies from agents (ordinary messages)
-  archive/<filename>.md
-  events/<sha256(stream\0to)>.json
-  events/<sha256(stream\0to)>.lock
-```
-
-Version-1 stream record:
-
-```json
-{
-  "version": 1,
-  "stream": "github:ci:pr-42",
-  "from": "example-linux.gh-ci",
-  "to": "example-linux.worker",
-  "pending": { "eventId": "failure", "filename": "1787…-6ktatz.md", "rendered": "---\n…" },
-  "recent": [
-    { "eventId": "running", "filename": "1787…-bn4myf.md" },
-    { "eventId": "pending", "filename": "1787…-a1b2c3.md" }
-  ]
-}
-```
-
-`recent` is a **bounded ring**, newest first, capped at K (default 128,
-per-source declarable). `recent[0]` is the stream head — the event supersede
-retires. `pending` is the single in-flight reservation.
-
-Publish transaction, under the per-(stream, recipient) flock:
-
-1. Read the record. If `pending` names *this* `eventId`, resume it with its
-   original filename and bytes. If `recent` already contains this `eventId`,
-   return that filename with `deduplicated: true` and stop.
-2. Atomically replace the record with `pending = {eventId, filename, rendered}`.
-3. `message::materialize_message_once(inbox, filename, rendered)` — the same
-   idempotent primitive `request::publish_once` already uses.
-4. If `--supersede` and `recent[0]` names a different filename, archive that
-   filename in the recipient's box. Repeated archive is idempotent by the
-   *Exactly-once-safe native bus* invariant.
-5. Atomically replace the record with `pending = null` and `recent` pushed.
-
-Step 3 before step 4 is deliberate: the new head is unread before the old one is
-retired, so a stream is never momentarily empty and a wakeup cannot be lost.
-
-Three properties fall out:
-
-- **Crash safety** with one durable file instead of eleven. A crash anywhere
-  between 2 and 5 is finished by the next emit for the same `(stream, event-id)`
-  with the identical filename and bytes. This is `request-state`'s reserve-then-
-  materialize discipline, but the reservation and the ledger are the same object.
-- **Constant write work and constant storage per stream.** MESSAGE-R08 requires
-  constant history-dependent write work for the sender ledger; the event store
-  achieves it *and* constant size, which the sender ledger deliberately does not.
-- **No shared producer lock.** The ingress prototype's structural complaint about
-  Rep 1 was that every pipe event serialises through the producing agent's single
-  `SentLock::exclusive`. The event lock is per (stream, recipient), so two streams
-  on one source never contend.
-
-### 2.5 Bounded dedup retention — the differentiation that earns its keep
-
-The ingress prototype's open question 4 is *"what retention rule applies to
-`request-state/outgoing` records after the inbox message is archived? They are the
-only thing preventing a much later replay from re-publishing, and nothing prunes
-them today."* Nothing in st2 answers it, and an unbounded per-event ledger on a
-chatty CI stream is an unbounded on-disk cost with no reclaim path.
-
-The event model answers it by declaring a bound rather than a policy: **dedup is
-guaranteed for the last K events of a stream, and is not guaranteed beyond that.**
-Replaying an event id that has aged out of the ring publishes a new item.
-
-This is exactly the tradeoff st2 already ratified as T01 — "a documented
-unsupported case is preferable to a hidden distributed guarantee" — and it is the
-concrete semantic difference between an event and a message that a unified model
-would have to fake. A message's sender history is *history*: MESSAGE-R03 requires
-exact traversal to genesis and refuses to weaken the coverage claim. An event
-stream is *current state*: only the head matters, the tail is evidence, and the
-system is allowed to forget. Forcing events into the Sent ledger would make a CI
-poller's ten-per-minute flap a permanent, ledger-chained, hash-verified part of
-some agent's conversational history.
-
-### 2.6 Supersession
-
-`--supersede` is per-emit, not per-stream, because the same stream can carry both
-kinds of fact (a CI *status* supersedes; a CI *comment* does not).
-
-A superseded event is archived, not deleted: it stays in `resources/archive/` as
-durable evidence and its archive filename is the receipt that stops it being
-resurrected. The recipient sees exactly one unread item per superseding stream.
-
-Whether this races DING's staged ownership is the riskiest claim in this design
-and is the subject of the spike in §5.
-
-### 2.7 What happens to service-principal requests
-
-They are absorbed. A request becomes:
-
-| Today | Target |
-|---|---|
-| `st2 request send --idempotency-key K --tag k=v --json` | `st2 event emit <to> --stream S --event-id E --subject … --json` |
-| `RequestEnvelope` JSON in the body, `st2-request` tag | the producer's own body; `stream`/`event-id` frontmatter |
-| `st2 request read <file> --json` | `st2 message read <file>` (and `--json`) |
-| `st2 request reply <file> --json …` | `st2 message reply <file>` |
-| `ReplyEnvelope`, `st2-request-reply` tag, `request-state/replies/` | the ordinary reply's `in-reply-to` and `from` |
-| `st2 request status --idempotency-key K --json` → `pending \| replied` | `st2 event status --stream S --event-id E --json` → `pending \| replied` |
-
-`event status` runs the same algorithm `request::status` runs today: look up the
-published filename in the stream record, then scan the source's inbox and archive
-for a message whose `in-reply-to` is that filename. The envelope validation goes
-away; the routing does not change at all.
-
-Two consequences worth stating plainly:
-
-- **An agent now has one reply verb.** It replies to a CI event exactly as it
-  replies to a peer, and does not have to inspect the sender to choose a command.
-  This is the concrete ergonomic payoff of unifying the *reply* path while
-  differentiating the *ingress* path.
-- **A reply to a source enters that agent's Sent history**, because the agent
-  genuinely said something. MESSAGE-R11 is amended accordingly in §4.
-
-### 2.8 How the notice renders
-
-`relationship_marker` gains one branch: a `from` that resolves to a declared
-source renders `~`.
-
-```
-[DING] ← example-linux.reviewer: please look at PR #42            (peer agent)
-[DING] ~ example-linux.gh-ci: CI failed on PR #42                 (world event)
-[DING] ? example-linux.mystery: …                                 (cannot tell)
-```
-
-`?` currently means three different things at once — "not a declared agent", "the
-catalog is unreadable", and "the supervisor chain is broken" — and the ingress
-prototype showed a principal makes it mean a fourth, "legitimate machine
-producer". Adding `~` gives `?` back a single meaning: *st2 could not resolve
-this*. That is a strict gain in the glyph vocabulary's information content even
-though the vocabulary grows by one symbol.
-
-The glyph is a fixed st2-chosen literal, not producer-supplied text; the source's
-bus id continues through `normalize_field`, so
-`poke_text_normalizes_and_bounds_untrusted_fields` and
-`malicious_controls_cannot_escape_the_single_paste_frame` are unaffected.
-
-### 2.9 Cursors: deliberately not a thing
-
-The lifecycle prototype notes that "nothing here addresses a cursor" and that a
-restarted pipe re-reads its source from scratch and relies on dedup. That is the
-right answer and the event model keeps it: a cursor is *the adapter's* state
-about *the external world*, not st2's state about the bus. A GitHub poller's
-cursor is a GitHub cursor; st2 storing it would mean st2 understanding GitHub,
-which #137 lists as a non-goal.
-
-What st2 owns is that a replayed event is not a second event, which the
-`(stream, event-id)` ring provides. An adapter that wants a durable cursor writes
-one in its own working directory.

-## 3. Concept count: today vs target
-
-| Dimension | Today | Target | Δ |
-|---|---:|---:|---:|
-| Producer identity kinds that can write an inbox | **5** (agent, principal, `ExternalInbox`, `st2.<host>`, literal `st2`) | **2** (agent, source) | −3 |
-| Declaration nodes for producers | **2** (`principal`, prototype `pipe` + `command`/`argv`/reserved `every`) | **1** (`source`) | −1 |
-| Durable producer stores | **3** (`sent/`, `request-state/outgoing/`, `request-state/replies/`) | **2** (`sent/`, `events/`) | −1 |
-| Durable file kinds in those stores | **11** (9 in `sent/` + 2 request-state) | **10** (9 + 1) | −1 |
-| Inbox record shapes | **3** (message, request envelope, reply envelope) | **2** (message, event) | −1 |
-| Serialized wire types | **10** (`MessageRow`, `SentMessageRow`, `SentMessages`, `SentCoverage`, `RequestEnvelope`, `ReplyEnvelope`, `PublicationRecord`, `PublishReceipt`, `IncomingRequest`, `RequestStatus`) | **7** (`MessageRow`+2 fields, `SentMessageRow`, `SentMessages`, `SentCoverage`, `StreamRecord`, `EventReceipt`, `EventStatus`) | −3 |
-| CLI commands | **11** (`message` ×7, `request` ×4) | **9** (`message` ×7, `event` ×2) | −2 |
-| Reply verbs an agent must choose between | **2** | **1** | −1 |
-| DING glyphs | **5** (`↺ ↓ ↑ ← ?`), `?` overloaded 4 ways | **6** (`↺ ↓ ↑ ← ~ ?`), `?` means one thing | +1 |
-| INVARIANTS rows on the ingress path | **2** | **3** | +1 |
-| Modules | `message.rs`, `request.rs` | `message.rs` (unchanged), `event.rs` | 0 |
-
-Wire types are counted as top-level serialized shapes; `StreamRecord`'s two inline
-sub-structs (`StreamEntry`, `StreamPending`) are counted with it, the same way
-`PublicationRecord` is counted as one today.
-
-Every axis moves down except two, and both increases are the earned semantics:
-the glyph that stops `?` lying, and the invariant row that states the stream
-bound. Nothing in the message subsystem changes.
-
-The shape of the win is worth naming: this design **differentiates the record and
-the producer identity** and **unifies the transport, the store location, the read
-commands, and the reply path**. It is not the pure differentiation pole — that
-design is measured and rejected in §7 — and it is not unification either, because
-the identity split and the stream semantics are load-bearing. It is the factoring
-that puts the split on the axis that carries meaning and takes it off the axis
-that does not.
-
----
-
-## 4. Requirement and invariant delta
-
-### R10 Agent-only identity — amended, as a reduction
-
-Current text: *"st2 models agents. Non-agent identities are unsupported."*
-
-Proposed: *"st2 models agents and event sources. An **agent** is the actor st2
-models: it has a persona, tasks, presence, a roster row, a supervisor edge, and
-durable sender-owned history. A **source** is a declared non-agent producer of
-world-events: it has a bus id, an event store, and an inbox for replies, and it
-has none of an agent's lifecycle, presence, or authority. No other identity may
-address the bus."*
-
-This is not a new exception. It replaces four undeclared exceptions (`principals/`,
-`ExternalInbox`, `st2.<host>`, the literal `st2`) with one declared one, and makes
-the vision's *"not a general messaging or identity platform for people, services,
-or arbitrary non-agent actors"* enforceable for the first time — today an
-unattributed `send_to_inbox` call can write any inbox with any `from` string.
-
-### R15 Bounded event coalescing — extended
-
-R15 today governs *filesystem watcher* streams. The event model puts a second
-coalescing point in the system (producer-side supersede), and it must be bounded
-in the same spirit. Proposed addition: *"A superseding event stream leaves exactly
-one unread item per (stream, recipient), and delivery attempts for that stream are
-bounded by DING's existing backoff, not by the producer's emission rate."*
-
-The exposure is real and is what the spike measures: a stream that supersedes
-faster than DING drains must not turn each supersede into a PTY probe. The
-existing **Bounded DING PTY probe churn** invariant
-(`deferred_delivery_backoff_bounds_short_lived_pty_attempts`) is the mechanism
-that has to hold.
-
-### MESSAGE-R01…R11 — R11 amended, the rest untouched
-
-MESSAGE-R01 through R10 are unaffected: ordinary sends, the sender ledger, the
-commit chain, coverage, and the `fractal-wire` shapes do not change. `MessageRow`
-gains two optional fields, which MESSAGE-R04's "optional metadata … preserve
-absent versus empty values" already accommodates and which the
-`a_field_this_reader_does_not_know_is_ignored_not_rejected` test already protects.
-
-MESSAGE-R11 today: *"Service-principal request publication state does not appear
-in ordinary Agent Sent history."*
-
-Proposed: *"Event publication state does not appear in ordinary Agent Sent
-history; a source has no Sent index. An agent's **reply** to an event is an
-ordinary send and does appear, because the agent genuinely authored it."*
-
-The inbound half — the half MESSAGE-R11 exists for, keeping machine ingress out of
-conversational history — is preserved exactly. The outbound half is deliberately
-relaxed, and the relaxation is an honesty improvement: today an agent's answer to
-a service is durably invisible in its own Sent history.
-
-MESSAGE-A01 ("declared senders … the eval-owned external requester remains an
-explicit compatibility capability") loses its exception clause: the eval requester
-becomes an ordinary source.
-
-### INVARIANTS: *Idempotent service requests* → *Idempotent event ingress*
-
-Replacement row, written to the same standard:
-
-> **Idempotent event ingress** — A declared non-agent source publishes one exact
-> event per `(stream, event-id, recipient)` into a canonical Agent Spec inbox.
-> Concurrent or crash-replayed publication reuses the reserved filename and bytes;
-> conflicting reuse of one event identity fails. One event fans out to several
-> recipients as several independent exactly-once operations. A reply routes to the
-> source's canonical inbox as an ordinary message, without an Agent Spec identity
-> or an orphan mailbox.
->
-> Proof: `tests/event_e2e.rs::stable_event_identity_publishes_exactly_one_canonical_message`;
-> `tests/event_e2e.rs::concurrent_replays_publish_exactly_one_event`;
-> `tests/event_e2e.rs::one_event_fans_out_to_several_recipients_without_collision`;
-> `tests/event_e2e.rs::a_fan_out_with_one_unknown_recipient_publishes_nothing`;
-> `tests/event_e2e.rs::conflicting_reuse_of_one_event_identity_fails`;
-> `tests/event_e2e.rs::a_reply_routes_to_the_source_and_status_is_a_tagged_json_union`;
-> `tests/event_e2e.rs::event_api_rejects_agent_impersonation_and_unknown_sources`
-
-### INVARIANTS: new row *Bounded event streams*
-
-> **Bounded event streams** — A superseding stream leaves exactly one unread item
-> in the recipient's inbox and its retired predecessors as durable archived
-> evidence; a superseded item is never resurrected and never re-notified. The
-> producer's per-stream dedup record is constant-size: exactly-once is guaranteed
-> for the last K event ids of a stream and explicitly not beyond.
->
-> Proof: `tests/event_e2e.rs::supersede_collapses_a_stream_to_one_unread_head_with_archived_evidence`;
-> `tests/event_e2e.rs::supersede_is_idempotent_and_crash_replay_safe`;
-> `tests/event_e2e.rs::the_stream_record_is_constant_size_and_forgets_beyond_its_bound`
-
-### INVARIANTS: *Fail-closed observed native DING* and *Exactly-once-safe native bus* — unchanged
-
-Both rows keep their text and all ~18 + 3 named proofs. Events use the same
-filename grammar, the same `list_inbox` shadowing, and the same archive receipts,
-so DING cannot tell an event from a message except through `relationship_marker`.
-The spike in §5 exists to prove that supersede does not violate either row rather
-than to amend them.
-
-### R23, R31, *Derived companion lifecycle*, *Runner-owned task identity*
-
-A source's task is an ordinary non-derived exec task, so it inherits restart
-policy, flapping, parking, crash-loop surfacing, and `st2 tasks --json` with no
-change to those contracts — the lifecycle prototype proved this for the derived
-shape, and the non-derived shape is strictly simpler. *Derived companion
-lifecycle* keeps its exact text and eleven proofs, because a source is not a
-companion.
-
-### Issue #137's acceptance criteria
-
-| Criterion | Status |
-|---|---|
-| A shell command emits an event to a catalog identity using stdin for the payload | Library-complete (`event::emit`); the CLI verb is unbuilt and its name is open in #137 |
-| A native recurring shell-driven source emits on a declared cadence, so a bootstrap timer can be removed | **Not addressed.** A `command`-bearing source removes the *supervision* half; the *cadence* half is deferred to `schedule` (open question 2) |
-| The producer supplies a stable source and event ID | `(from, stream, event-id)`, with `from` a declared identity rather than a free string |
-| Replaying the same identity is idempotent, including concurrent retries | `concurrent_replays_publish_exactly_one_event` (12 threads) |
-| JSON output includes recipient, receipt id, and created vs deduplicated | `EventReceipt { to, filename, deduplicated, superseded }` |
-| A new event follows inbox → DING; a duplicate does not DING again | `stable_event_identity_publishes_exactly_one_canonical_message` + the archive receipt; DING's `new_arrivals` never re-emits a filename it has seen |
-| The on-disk representation stays compatible with normal list/read/archive/thread | By construction — it *is* a normal message file |
-| Tests cover retry, concurrent duplicate emission, and a producer crash/retry boundary | `supersede_is_idempotent_and_crash_replay_safe` covers the crash boundary |
-
-#137's own open questions get concrete answers: extend frontmatter rather than
-keep a separate receipt index (the receipt index would be a second store to keep
-consistent with an immutable message); deduplication lives at the **producer**,
-scoped per recipient, not per recipient-catalog or at a shared bus scope; the
-retention rule is the bounded ring in §2.5; and `event emit` beats `pipe` as the
-verb because `pipe` names the *source*, not the act.
-
-### DQ1
-
-The event model supplies three of DQ1's four unspecified items: the KDL shape
-(`source`), the event inbox (the ordinary inbox, differentiated by producer
-identity and stream frontmatter), and the deduplication boundary
-(`(from, stream, event-id)` with a declared bound). Execution receipts are the
-`EventReceipt`/`EventStatus` pair. The *cadence* half — #137's "a native recurring
-shell-driven source can emit on a declared cadence … allowing a bootstrap system
-timer to be removed" — is deliberately left to the reserved `schedule` node; see
-the open questions.

-## 5. Spike: the riskiest seam
-
-See §6 for what was built and measured.
-
-The seam chosen is **producer-side supersede against DING's staged ownership**,
-because it is the only place where a genuinely new semantic (supersession)
-collides with a sacred invariant, and because if it fails the differentiation
-argument collapses — supersession is the main semantic a unified model would
-have to fake.
-
-The three claims under test:
-
-1. When a producer supersedes (archives) event *N* **while DING has already
-   staged N's notice into a composer**, event *N+1* still delivers and *N* is
-   never re-pasted.
-2. The archived staged head does not stall FIFO indefinitely.
-3. A stream that supersedes faster than DING drains does not turn each supersede
-   into a PTY probe (the R15 / *Bounded DING PTY probe churn* exposure).
-
----
-
-## 6. Spike results
-
-### What was built
-
-Strictly additive: `src/request.rs` is untouched and every `tests/request_cli.rs`
-proof — including the four named by the *Idempotent service requests* invariant —
-stays green. The absorption in §2.7 is a design proposal with a written
-replacement invariant row, not a deletion performed here.
-
-`INVARIANTS.md` is deliberately **unedited**. The replacement and new rows in §4
-are proposed text with their expected proof names, which is the right state for a
-two-pole exploration: amending a sacred row is a decision for whichever design is
-adopted, and `tests/invariants.rs::qualified_proof_references_resolve` would fail
-against a row whose proofs live in an unadopted branch.
-
-| Area | File | What |
-|---|---|---|
-| Source declaration | `src/event.rs` | `sources/<host>/<name>/source.kdl`, `discover_sources`, `resolve_source`, agent-collision refusal |
-| Event record | `src/event.rs::render_event` | `stream:` / `event-id:` frontmatter on an ordinary message |
-| Durable store | `src/event.rs::StreamRecord` | one constant-size file per `(stream, recipient)`: bounded `recent` ring + single `pending` reservation + per-stream flock |
-| Publish | `src/event.rs::emit` | reserve → materialize → supersede → advance, fan-out over N recipients |
-| Reply channel | `src/event.rs::status`, `src/message.rs::DeliveryEndpoint::Source` | `pending \| replied` from ordinary `in-reply-to`; an agent replies with `message reply` through its own Sent ledger |
-| Notice | `src/ding/mod.rs::SOURCE_MARKER`, `RelationshipResolver::is_source` | `~` for a declared source |
-| Race proofs | `src/ding/mod.rs` tests | supersede against staged payload ownership |
-| Ingress proofs | `tests/event_e2e.rs` | 12 tests |
-
-### Claim 1 — supersede of a *staged* head never re-pastes, and the successor delivers
-
-`src/ding/mod.rs::a_producer_supersede_of_a_staged_event_never_repastes_and_the_successor_delivers`
-
-Real catalog, real source, real emits. DING stages the `failure` notice and owns
-it; the producer then emits `success` with supersede, which materializes `success`
-and archives `failure` **under DING's feet**. The measured result:
-
-- `failure` appears in the fresh-paste log exactly once, ever;
-- the only staged retry is `failure`, and it is inspection-only — the archived,
-  positively-`NotRetained` head releases FIFO without a second paste;
-- `success` is then pasted once and delivered; the queue drains empty.
-
-**No change to `flush_pending` or `prune_archived_pending` was needed.** The rules
-that already exist — "staged ownership survives archive and never repastes" and "a
-maintained adapter's positive `NotRetained` observation releases only an already
-archived staged head" — turn out to be exactly the rules a producer-side supersede
-needs. That is the single most important result in this spike: supersession is
-*already* safe against the DING invariant that governs it, because archiving under
-DING is a case the invariant was designed for.
-
-### Claim 2 — a superseded head that is still retained blocks FIFO instead of leaking a paste
-
-`src/ding/mod.rs::a_superseded_but_still_retained_staged_event_keeps_ownership_without_repasting`
-
-The pessimistic branch: the adapter still sees the superseded notice in the
-composer. Ownership is retained, the successor is **not** pasted on top of a live
-payload, and later FIFO work stays blocked — which is the correct fail-closed
-behaviour and the one the invariant demands. Supersede therefore cannot be used to
-force a second paste into an occupied composer.
-
-### Claim 3 — a fast-superseding stream does not multiply PTY delivery attempts
-
-`tests/event_e2e.rs::a_fast_superseding_stream_does_not_multiply_pty_delivery_attempts`
-
-An end-to-end `run_ding` loop over a real inbox, with a `Poker` whose every
-attempt defers (the worst case: the notice is never retired). 24 supersedes fired
-into the watched inbox — 48 filesystem mutations, each one a watcher wake:
-
-```
-CHURN: 24 supersedes in 145.739138ms -> 1 fresh poke(s), 0 staged retry/retries, 1 unread
-```
-
-**One** PTY delivery attempt for 24 events, and the agent is left with exactly one
-unread item rather than 24. The existing `DELIVERY_RETRY_BACKOFF` decouples
-delivery attempts from producer rate, so *Bounded DING PTY probe churn* holds
-against the new coalescing point without a new bound. R15's proposed extension in
-§4 is therefore a statement of what already happens, not a new mechanism.
-
-### Ingress, fan-out, retention, reply — `tests/event_e2e.rs` (12 tests, all green)
-
-| Test | What it proved |
-|---|---|
-| `stable_event_identity_publishes_exactly_one_canonical_message` | One `(stream, event-id, recipient)` → one item; three replays return the original filename with `deduplicated: true`; the item is an ordinary readable message with the producer's own body and subject — no envelope, no `request <key>` subject |
-| `concurrent_replays_publish_exactly_one_event` | 12 racing threads observe one canonical filename; one inbox item |
-| `one_event_fans_out_to_several_recipients_without_collision` | Three recipients, three exactly-once operations, one copy each; replaying the fan-out deduplicates all three. This is the defect the ingress prototype measured in the principal path, fixed by scoping the ledger the way MESSAGE-R07 already does |
-| `conflicting_reuse_of_one_event_identity_fails` | Different bytes under one identity is a hard failure, never a second item |
-| `a_reply_routes_to_the_source_and_status_is_a_tagged_json_union` | An agent answers with **`message reply`**; the reply lands in the source's inbox; `status` flips `pending` → `replied` by `in-reply-to` alone. The reply is in the agent's Sent history and the source has no `resources/sent` — MESSAGE-R11's inbound half preserved, outbound half deliberately relaxed |
-| `event_api_rejects_agent_impersonation_and_unknown_sources` | An undeclared producer is refused; a source colliding with an Agent Spec identity is refused; an agent still wins as a recipient, so a source cannot intercept peer traffic |
-| `supersede_collapses_a_stream_to_one_unread_head_with_archived_evidence` | Four CI transitions → exactly one unread (`success`) and three durable archived predecessors; replaying a superseded event returns its filename and never resurrects it |
-| `a_fan_out_with_one_unknown_recipient_publishes_nothing` | R19 admission: one bad address in a fan-out refuses before any write and reserves no producer state, so a caller can never lose the receipt for a partially published fan-out |
-| `supersede_is_idempotent_and_crash_replay_safe` | Both crash windows. Reserve→materialize: the replay publishes under the *reserved* filename. Materialize→advance (the likelier one): the replay **adopts the already-materialized file** rather than minting a second one, then finishes the supersede and the ring advance. Repeating either emit supersedes nothing new; the stream is never momentarily empty |
-| `the_stream_record_is_constant_size_and_forgets_beyond_its_bound` | 129 events → **one** record file with `recent.len() == 128`; the aged-out id is gone, and replaying it is asserted to be a *new* publication rather than silently claimed as exactly-once |
-| `a_source_event_renders_its_own_marker_and_question_mark_keeps_one_meaning` | `[DING] ~ example-linux.gh-ci: CI failed on PR #42 [id:…]`; an unresolvable sender is still `?`; an agent is never mistaken for a source |
-| `a_fast_superseding_stream_does_not_multiply_pty_delivery_attempts` | see claim 3 |
-
-Plus `src/event.rs` unit proofs that one declaration node covers both a supervised
-and an externally driven source
-(`one_declaration_covers_a_supervised_and_an_externally_driven_source`), that
-content must match its canonical path, and that the ring is bounded and
-newest-first.
-
-### What the spike disproved
-
-Nothing in the design, but two things I expected to have to build turned out to be
-unnecessary, and both make the design *smaller* than drafted:
-
-- **No DING change was needed for supersession.** The draft anticipated at least a
-  `prune_archived_pending` adjustment. There is none. The only DING edit in the
-  whole spike is the `~` glyph branch.
-- **No new bound was needed for R15.** `DELIVERY_RETRY_BACKOFF` already decouples
-  probes from producer rate by two orders of magnitude in the measured case.
-
-### Regression status
-
-`nix develop -c cargo test --workspace --no-fail-fast`, with the spike applied:
-**40 suites green, 7 suites failing, 9 failing tests.** The same seven suites fail
-byte-identically at the unmodified base commit `8ff140e` — same test names, same
-pass counts — so every one is pre-existing:
-
-| Suite | Failing test(s) |
-|---|---|
-| `catalog_diff` | `classification_only_and_nested_agent_filename_changes_are_exact` |
-| `eval_run_e2e` | `canonical_agents_freeze_the_admitted_route_across_post_boot_catalog_mutation` |
-| `eval_up` | `st2_up_once_atomically_respawns_a_hard_killed_agent`, `st2_up_boots_a_specs_team`, `st2_down_tears_down_a_spec_fleet`, `st2_up_spec_supervises_and_respawns_a_killed_agent` |
-| `materialize` | `up_materialize_only_writes_the_overlay_without_needing_pty` |
-| `native_only` | `clean_path_supports_help_validate_env_and_doctor`, `tracked_product_surface_contains_only_native_names` (names only `docs/vrs/spec.md`, untouched here) |
-| `targeted_reconcile` | `targeted_once_real_pty_preserves_sibling_generation_across_selected_lifecycle` |
-| `task_inventory_cli` | `completed_catalog_aba_during_runtime_observation_is_incomplete` |
-
-This set matches the lifecycle prototype's independently recorded pre-existing
-failures exactly.
-
-**Every INVARIANTS-named suite is green**, including the ones this spike touches
-directly: `--lib` (339, covering all 18 *Fail-closed observed native DING* proofs,
-the *Exactly-once-safe native bus* proofs, and the two new supersede-race tests),
-`--test request_cli` (all four *Idempotent service requests* proofs),
-`--test message`, `--test message_cli`, `--test invariants`, `--test run`,
-`--test nomad_survival`, `--test doctor`, `--test reconcile`, `--test pty`,
-`--test exec_backend`, `--test status_agents`, `--test transport_isolation`,
-`--test predecessor_ding_migration`, and the new `--test event_e2e` (12).
-
-### What the spike did *not* cover
-
-- **Supervising a standalone source's task.** §10 cost 1 is unmeasured. The
-  lifecycle prototype proved the *derived companion* shape works with a two-line
-  gate change; a non-derived, agent-less top-level task is a different and larger
-  change to `src/reconcile.rs`'s target loop, and this spike deliberately spent its
-  budget on the seam that could invalidate the design rather than the one that is
-  mechanical.
-- **CLI surface.** `st2 event emit` / `st2 event status` are library functions
-  here, not `main.rs` subcommands. #137 leaves the command name open.
-- **`ExternalInbox` migration** to a source, and the reserved `st2.<host>` source.
-  Both are proposed in §2.1 and neither is implemented.
-
----
-
-## 7. Rejected: a separate event store
-
-The pure differentiation design — events in `resources/events/` on the recipient
-with their own notice path — was evaluated and rejected. Its measured cost:
-
-- **Five inbox readers** would each need a second source and a merge rule:
-  `src/agents.rs:147` (roster counts), `src/claude_mcp.rs:96`, `src/pi_channel.rs:109`,
-  `src/codex_app_server.rs` (native delivery), `src/main.rs:2341` (`message ls`).
-  #238's bounded-body delivery envelope would need to span both.
-- **DING's `PendingNotice` becomes a four-variant enum** and `flush_pending`'s
-  single-staged-payload FIFO becomes a two-queue merge with an ordering rule. That
-  lands inside a machine with ~18 named invariant proofs; `prune_archived_pending`
-  and `new_arrivals` would both need a second archive semantics.
-- **The *Exactly-once-safe native bus* invariant's archive-receipt guarantee would
-  have to be reimplemented** for the second store, or events would lose the very
-  property that makes supersede safe.
-
-What it buys: retention policy independence, and events not appearing in
-`message ls`. Both are obtainable at near-zero cost from a `stream:` frontmatter
-key plus a filter, and the retention story in §2.5 lives at the *producer*, where
-it belongs, not at the recipient.
-
-Coalescing is not on the list of benefits: the ingress prototype already proved
-coalescing cannot live in DING regardless of where events are stored, because
-`flush_pending` sees one notice at a time.
-
-Verdict: a separate store adds one durable store, one notice path, one enum
-variant set, and five reader merges to buy two things a frontmatter key already
-buys. It loses by every axis of the objective function.
-
----
-
-## 8. The strongest argument against this design
-
-Steelmanned unification: *after the factoring in §2, a message and an event
-differ only in two optional frontmatter keys, one glyph, and a producer-side
-ledger shape. All three differences are producer-side or presentation-side. The
-record is the same record, in the same directory, with the same filename grammar,
-read by the same commands, delivered by the same transport. Calling that a
-"distinct concept" is naming, not architecture. The honest version of this design
-is "one inbox item, two producer identity kinds", and `st2 event emit` should just
-be `st2 message send --stream --event-id --supersede`, which is exactly what issue
-#137's shipped-direction PR #138 converged on and what its comment thread
-proposed: "adds optional `--source` and `--event-id` flags and frontmatter to
-ordinary `st2 message send`. Without those flags, message behavior and output do
-not change."*
-
-This is a strong argument and it is partly correct. Three things answer it:
-
-1. **The identity split is load-bearing independently of the record split.** A CI
-   poller must not acquire a roster row, a presence record, a derived DING
-   sidecar, or doctor health obligations. That is true whether or not events and
-   messages share a record shape, and it is the finding both prototypes
-   independently reached. The unified position must still declare sources.
-2. **The publication transactions genuinely differ, and cannot merge.** An
-   ordinary send takes the agent's single `SentLock::exclusive`, writes a pending
-   record, a row, an immutable commit node, and an atomically replaced head, and
-   MESSAGE-R03 then requires exact traversal to genesis. An event takes a
-   per-stream lock and replaces one constant-size record. Routing an event through
-   `send_to_resolved_inbox` means either giving every CI flap a ledger-chained,
-   hash-verified permanent place in an agent's conversational history, or adding a
-   bypass flag to the send path — and a bypass flag is a second mechanism wearing
-   the first one's name.
-3. **Supersede and bounded retention have no meaning for a message.** "Archive the
-   thing I said last time before saying this" is incoherent for speech and correct
-   for a status fact. "Exactly-once for the last 128, then not" is unacceptable for
-   an agent's own history and right for a CI stream.
-
-Where the unification argument *wins*, and this design concedes it: the reply
-path, the transport, the storage location, the read commands, and the DING
-machinery. Those are unified here, and the concessions are why this design deletes
-more than it adds.
-
----
-
-## 9. Migration and compatibility
-
-Per the guidance, fresh namespaces over in-place migration.
-
-| Thing | Verdict |
-|---|---|
-| `principals/<host>/<id>/principal.kdl` | Fresh namespace `sources/<host>/<name>/source.kdl`. Existing catalogs: `principals/` continues to be discovered as sources with no `command` for one release, with a `validate` warning naming the new path. No state moves; a principal's inbox/archive are already at `resources/`. |
-| `resources/request-state/outgoing/` | Left in place, no longer written. A one-shot `st2 event import-request-state` is *not* proposed: dedup records only prevent re-publication of events that have already been delivered, so the worst case of ignoring them is one re-delivery of an event whose last emission predates the upgrade. |
-| `resources/request-state/replies/` | Left in place, no longer written or read. |
-| `st2 request …` | Kept as a deprecated alias for one release: `request send` → `event emit` with `--stream <key> --event-id <key>` derived from the idempotency key, `request reply` → `message reply`, `request status` → `event status`. `request read` is dropped; `message read` supersedes it. |
-| In-flight typed requests across the upgrade | An unreplied request published by the old code is an ordinary inbox message with a JSON body; `message read` shows it, `message reply` answers it, and the old `request status` alias still finds the reply because both scan `in-reply-to`. No fencing needed. |
-| `MessageRow` consumers | Additive optional fields only; `crates/fractal-wire` has no `deny_unknown_fields` and `a_field_this_reader_does_not_know_is_ignored_not_rejected` is the standing proof. |
-| `RequestEnvelope` / `ReplyEnvelope` / `PublicationRecord` | All three carry `deny_unknown_fields`. They are **not** extended — they are retired with the code that reads them. |
-| The `~` glyph | Every agent sees this string. It is additive: no existing glyph changes meaning, and `?` becomes strictly more precise. |
-
----
-
-## 10. Costs and risks, honestly
-
-1. **Sources are a new top-level declaration kind in the reconciler.** A source
-   with a `command` compiles to a `TaskTarget` that is not owned by an `AgentSpec`.
-   Everything downstream of `TaskTarget` (flapping, park, `exec_backend`,
-   `task_inventory`) is already generic, but `src/reconcile.rs`'s target loop
-   (`:860`), materialization, doctor, and `st2 tasks --json`'s agent join all
-   assume an `AgentSpec` owner. This is the largest implementation cost in the
-   design and it is *not* what the spike measured. Estimated 150–250 lines across
-   `reconcile.rs`, `run.rs`, `doctor`, and `task_inventory.rs`, plus discovery.
-   The lifecycle prototype's nested `pipe` shape avoids it entirely at the cost of
-   losing fan-out and re-introducing marker-argv payload smuggling.
-2. **`?` regressions during rollout.** Until a catalog declares its sources, a
-   pipe adapter's events render `?` — the same as today, but the design's headline
-   benefit is invisible until the catalog is authored.
-3. **The bounded ring is a real semantic loss** relative to today's unbounded
-   `request-state`. A source that replays an event id from more than K events ago
-   publishes a duplicate. K must be chosen so that no realistic replay window
-   exceeds it; 128 is a guess, not a measurement.
-4. **Two writers to one recipient inbox now take different locks.** An agent's
-   send holds `resources/sent/.lock`; a source's emit holds its own per-stream
-   lock. They do not exclude each other. This is already true today
-   (`request::publish_once` takes no sender lock at all) and is safe because
-   `materialize_message_once` is atomic on a fresh random filename, but it means
-   inbox writes are not globally serialised and never were.
-5. **`event status` is O(inbox + archive) on the source's boxes**, exactly like
-   `request::status` today. A source that receives many replies will want the
-   MESSAGE-R10 treatment eventually.
-6. **Source discovery must fail closed, and in the spike it does not.** The spike's
-   `lookup_source` swallows a discovery error (`.ok()?`) and
-   `RelationshipResolver::read` uses `.unwrap_or_default()`, so a malformed
-   `source.kdl` makes that source silently *invisible*: a reply to it reports "no
-   agent … found", and its events render `?` instead of `~`. That is the opposite
-   of how the agent side behaves — `RelationshipResolver::valid` goes false on any
-   discovery error and forces `?` everywhere on purpose — and it is against R23 and
-   *Tracked workspaces fail closed*. The shipped version must surface a source
-   declaration error as a `validate` diagnostic and as an explicit unresolved
-   state, never as absence. Noted here rather than fixed, because it is a
-   correctness rule for the real implementation, not a question the spike answers.
-7. **Same-millisecond ordering is still unrecoverable.** The ingress prototype
-   proved two events sharing a millisecond drain in random-suffix order. A
-   high-rate webhook fan-in needs a stronger ordering token than the frozen
-   `<unix-ms>-<rand6>` grammar, and this design does not supply one.
-
----
-
-## 11. Open questions only a human can settle
-
-1. **Do sources declare their recipients, or does each emit choose?** This design
-   says each emit chooses, which keeps the declaration minimal and lets a source
-   route by content. The cost is that an agent's declaration does not say which
-   sources can wake it. The alternative — a `subscribe "gh-ci"` node on the agent —
-   adds a declaration node and a second place recipients are written.
-2. **Cadence.** #137 explicitly wants a declared cadence so a systemd timer can be
-   removed. This design leaves `every` to the reserved `schedule` node rather than
-   putting a sleep loop inside a source, following the lifecycle prototype's
-   reasoning that an interval-respawn loop makes the source a second lifecycle
-   owner. Whether `schedule` targets a source, or a source grows `every` handled by
-   the supervisor's restart policy, is unsettled.
-3. **Is `~` the right glyph?** It is one character every agent sees on every
-   machine event, forever.
-4. **Is the reserved `st2.<host>` source worth it**, or should the runner's
-   crash-loop notice stay an unattributed `send_to_inbox`? Making it a source is
-   what takes the identity count from 3 to 2, but it puts the supervisor's own
-   escalation path behind a declaration.
-5. **K, the dedup ring bound.** 128 is a guess. The right value depends on how far
-   back a real adapter replays after a restart.
-6. **Does `st2 event emit` also want #277's `steer` / `queue` field?** Three
-   separate proposals now want a field on the send envelope — #137's provenance
-   pair, #49's thread/topic identity, and #277's delivery mode. `stream` is
-   arguably #49's "topic" for machine facts; whether the two should be one concept
-   is a real question this design does not answer.
-7. **What happens to events while an agent is suspended?** A source is
-   independently supervised here, so unlike the nested-pipe shape it keeps running
-   and keeps filling a suspended agent's inbox. That is right for an audit trail
-   and wrong for a live feed; today's nested prototype makes the opposite choice.
-
-## Method
-
-Design exploration from the differentiation pole with an executable spike of
-the riskiest seam: §1–§4 derive the target event model (stream identity,
-producer-side supersession, bounded per-stream state, request absorption) from
-the code and VRS on `main` (8ff140e); §5–§6 document the spike — supersession
-racing DING staged-payload ownership, ingress idempotency under 12-way
-concurrency, fan-out, retention bounds, reply routing — run as
-`tests/event_e2e.rs` (12 tests) plus DING-side proofs in the exploration
-worktree.
-
-## Result
-
-See §3 for the concept-count table and §6 for spike outcomes: supersession
-needs zero DING changes (staged head pasted at most once ever; 24 supersedes
-in 145.7 ms → 1 fresh poke, 0 staged retries, 1 unread), R15 holds, the
-stream record stays constant-size, and `?` regains a single meaning via the
-new event marker. Full-workspace failure set identical to baseline.
-
-## Conclusion
-
-Events earn a distinct record kind on the shared transport: the semantics CI
-actually needs — supersession, bounded retention, mandatory event identity —
-are incoherent inside the append-only sender ledger, while the transport,
-storage location, read commands, and reply path unify. Decision 0004 adopted
-this model; decision 0005-streams-are-agent-nested-and-stream-named moved the declaration onto the agent and renamed
-the vocabulary stream-centric (this document's per-emit "stream" axis became
-`key`, and its top-level `source` declaration became the reserved future
-generalization).
-
-## VRS Impact
-
-Realized as the `04-stream` subsystem: STREAM-R03..R07 carry this document's
-ingress, retention, and supersession claims; spec DQ-S1..DQ-S7 carry its open
-questions; `.decisions/0004` records the record-kind choice with this
-exploration as primary evidence.

-# Pipes ingress and delivery prototype
-
-Date: 2026-08-20
-
-## Question
-
-A "pipe" lets an agent subscribe to external events — GitHub CI updates for a
-PR, timers, monitoring alerts — and be woken by each one through st2's existing
-durable inbox and DING delivery. Two representations can carry that event into
-`resources/inbox/`:
-
-- **Rep 1 "message path"** — the event is an ordinary bus message with an
-  idempotency key. This is the shape of draft PR
-  [#138](https://github.com/compoundingtech/st2/pull/138) against issue
-  [#137](https://github.com/compoundingtech/st2/issues/137).
-- **Rep 2 "principal path"** — the event is a typed service-principal request
-  published by `src/request.rs` from a declared
-  `principals/<host>/<identity>/principal.kdl`.
-
-Which one should own external-event ingress, and what does each actually do at
-the inbox, the DING notice, and the provenance boundary?
-
-## Method
-
-Both representations were driven end to end on current HEAD through the real
-CLI and the real library, in temporary catalogs, by
-`tests/pipe_ingress.rs` (16 tests). Rep 1 needed two small additions to be
-comparable at all (below). Rep 2 needed no code change. A no-network fake
-GitHub CI poller, `examples/pipes/fake-gh-ci-poller.sh`, drives the
-`pending → running → failure → success` transitions from a local state file and
-is exercised by `fake_github_ci_poller_walks_pending_to_success_with_idempotent_polls`.
-
-### What PR #138 contributes
-
-Nothing that survives. The fetched diff (`gh pr diff 138`) adds only
-`--idempotency-key`, not `--source`/`--event-id`, and implements deduplication
-by scanning the recipient inbox and then the archive under an inbox flock —
-"if the archived message is deleted, st2 forgets the key". HEAD already exposes
-`--idempotency-key` on `st2 message send` (`src/main.rs:701`) backed by the
-strictly stronger sender-owned key ledger (`src/message.rs::publish_key`,
-`keyed_record`), which is scoped by `(canonical sender, canonical recipient,
-key)` per MESSAGE-R07 and survives recipient deletion. #138 is superseded and
-should be closed rather than rebased. Its `--source`/`--event-id` intent, which
-lives in issue #137 and not in the PR, is what this spike reimplemented.
-
-### Spike code
-
-| Change | Where |
-| --- | --- |
-| `Message.source` / `Message.event_id` frontmatter fields | `src/message.rs:144` |
-| `Provenance` (idempotency key + source + event id) and `SendOutcome` (`to`, `filename`, `deduplicated`) | `src/message.rs:156`, `src/message.rs:174` |
-| Frontmatter render/parse for `source:` / `event-id:` | `src/message.rs:279`, `src/message.rs:345` |
-| `send_to_resolved_inbox` returns `SendOutcome`; `keyed_record` and recovered-intent hits report `deduplicated: true` | `src/message.rs:1431`, `src/message.rs:1553`, `src/message.rs:1564` |
-| `st2 message send --source --event-id --json`, key derived as `<source>#<event-id>` | `src/main.rs:703`, `src/main.rs:2198` |
-| `SendReceiptJson`; `source` / `eventId` in `message ls --json`, `message read --json`, `message read` human output | `src/main.rs:2506`, `src/main.rs:2647`, `src/main.rs:2696`, `src/main.rs:2423` |
-| Evidence suite | `tests/pipe_ingress.rs` |
-| Fake CI poller demo | `examples/pipes/fake-gh-ci-poller.sh` |
-
-`src/ding/mod.rs` delivery logic is untouched; only its test fixture gained the
-two new `Message` fields.

-## Result
-
-### The two representations on disk
-
-One CI failure event, emitted both ways into the same inbox:

- "source":"github:ci:pr-42"},"body":{"pr":42,"state":"failure"}}
-```
-
-### 0. Sender identity — the constraint that decides the rest
-
-`send_to_resolved_inbox` resolves `from` against Agent Specs and refuses
-anything else. The message path therefore cannot carry a non-agent producer
-identity in a real catalog:
-
-```
-$ st2 message send h.worker --as h.pipe-gh-ci --source github:ci --event-id run-1 ...
-Error: no agent 'h.pipe-gh-ci' found in catalog /tmp/…
-```
-
-Proof: `rep1_refuses_a_non_agent_sender_but_rep2_accepts_a_declared_principal`.
-The same principal is accepted by Rep 2 and produces exactly one inbox item.
-Making Rep 1 work requires declaring the producer as a full Agent Spec, which
-buys a roster row, a presence record, a derived DING sidecar under "Derived
-companion lifecycle", and doctor health checks that a CI poller never wanted —
-directly against root R10's agent-only identity intent and MESSAGE-A01.
-
-The residual authoring state after one event makes the asymmetry concrete:
-
-```
-h/pipe-agent/agent.kdl
-h/pipe-agent/resources/sent/.lock
-h/pipe-agent/resources/sent/commits/9ca9a2ad….json
-h/pipe-agent/resources/sent/index.json

-
-principals/h/pipe-gh-ci/principal.kdl
-principals/h/pipe-gh-ci/resources/request-state/outgoing/07897efd….json
-```
-
-### 1. One event → exactly one durable inbox item, including concurrent replay
-
-Both representations pass. One sequential emission plus 12 threads replaying the
-same `(source, event-id)`: every invocation returns the same filename, every
-replay reports `deduplicated: true`, and the inbox holds exactly one item.
-
-- `rep1_concurrent_and_sequential_replays_publish_exactly_one_inbox_item`
-- `rep2_concurrent_and_sequential_replays_publish_exactly_one_inbox_item`
-
-Reusing one event identity with different content fails on both rather than
-publishing a second item —
-`both_representations_refuse_conflicting_reuse_of_one_event_identity`. Rep 2's
-message is the sharper one: `idempotency key reused with different request`.
-
-The mechanisms differ. Rep 1 reserves nothing at the recipient; it consults the
-sender's `sent/keys/<sha256>.json` under an exclusive flock (MESSAGE-R08). Rep 2
-atomically hard-links one `request-state/outgoing/<sha256>.json` record that
-pins the message filename in advance, then finishes an interrupted publication
-with `materialize_message_once`. Rep 2's record is what makes a producer *crash*
-between reservation and publication safe; Rep 1 gets the same property from its
-pending-intent recovery.
-
-### 1b. Fan-out — one event, several agents
-
-The obvious pipe shape is one CI event waking more than one agent, and it is the
-one axis where the principal path is worse out of the box
-(`one_event_fans_out_on_rep1_but_collides_on_rep2`):
-
-- **Rep 1 fans out correctly.** `key_path(root, to, key)` includes the canonical
-  recipient, so the same `(source, event-id)` addressed to `h.worker-a` and
-  `h.worker-b` is two operations and two messages, each still exactly-once.
-- **Rep 2 refuses the second recipient.** `publish_once` hashes only the state
-  key into the principal's `request-state/outgoing`, then rejects the reused
-  record because `record.to != to`:
-
-  ```
-  Error: idempotency key reused with different request
-  ```
-
-The producer workaround is to fold the recipient into the key
-(`run-5@h.worker-b`), which the test confirms works and which is exactly what
-Rep 1's MESSAGE-R07 scoping does for free. The proper fix is a one-line change
-to Rep 2's state key — the same `(caller, recipient, key)` scoping the message
-path already uses. This is a real defect in the recommended path, not a reason
-to prefer the other one.
-
-### 2. A duplicated event after archive
-
-Neither re-notifies, but they get there differently, and the difference is
-visible on raw disk.
-
-**Rep 1 never re-creates the file.** `keyed_record` returns before
-`deliver_record`, so a replay of an archived event touches only the sender
-ledger. Asserted on raw disk before any logical read:
-`rep1_replay_after_archive_never_recreates_the_inbox_file`.
-
-**Rep 2 does re-create it.** `materialize_message_once` consults only the inbox,
-so a post-archive replay re-links the canonical filename into
-`resources/inbox/`. The "Exactly-once-safe native bus" archive receipt is what
-makes that harmless: `list_inbox` shadows the restored replica, deletes it, and
-`ding::new_arrivals` returns empty. Both halves asserted in
-`rep2_replay_after_archive_recreates_the_file_but_the_archive_receipt_suppresses_it`.
-
-Rep 2 therefore depends on an existing invariant for correctness where Rep 1 is
-correct by construction. That is a real difference, though the invariant is
-load-bearing anyway and proven by `archive_receipt_suppresses_and_idempotently_cleans_a_restored_inbox_copy`.
-
-### 3. What DING actually renders
-
-`ding::poke_text` rendered over messages that were really emitted, in a catalog
-where `worker` and the Rep 1 producer are siblings under one supervisor
-(`ding_notice_rendering_differs_across_representations`):
-
-```
-REP1 DING: [DING] ← h.pipe-agent: CI failure on PR #42 [id:vvje5g]
-REP2 DING: [DING] ? h.pipe-gh-ci: request github:ci#run-11 [id:ykndpr]
-RAW  DING: [DING] ? pipe:gh-ci: CI failure on PR #42 [id:y5za7n]
-```
-
-Three findings:
-
-- **Rep 2 renders `?`.** `relationship_marker` resolves the claimed sender
-  against Agent Specs only; a principal is not one. This matches the existing
-  `nightly-timer` case in `src/ding/mod.rs`. `?` currently means *both* "not a
-  declared agent" and "the catalog is unreadable / the chain is broken" — it
-  cannot say "this is a machine producer, not a peer".
-- **Rep 2's subject is useless.** `request::publish` hardcodes
-  `format!("request {idempotency_key}")`, so the CI state never reaches the
-  notice. The poller run makes the cost obvious — four events, four notices, no
-  human-readable content beyond the key:
-
-  ```
-  POLLER DING: [DING] ? h.pipe-gh-ci: request github:ci:pr-42#pending [id:xaw0pe]
-  POLLER DING: [DING] ? h.pipe-gh-ci: request github:ci:pr-42#running [id:37e4fd]
-  POLLER DING: [DING] ? h.pipe-gh-ci: request github:ci:pr-42#failure [id:mxhpt4]
-  POLLER DING: [DING] ? h.pipe-gh-ci: request github:ci:pr-42#success [id:fmz6sn]
-  ```
-
-  Because the key is doing double duty as the only visible label, this is
-  legible only by accident of how the poller composes it.
-- **Rep 1 renders a lie.** Because the producer had to be declared as an Agent
-  Spec, the marker resolves to a real hierarchy glyph (`←` for a sibling). A
-  machine event is presented to the agent as peer-agent traffic.
-
-### 4. Burst behavior
-
-Ten rapid distinct events (a CI status flap) through each representation land
-completely — nothing coalesces, nothing is dropped
-(`a_ten_event_burst_lands_completely_and_drains_fifo_by_filename_order`):
-
-```
-REP1 burst: 0 same-millisecond collisions among 10 events
-REP1 burst: drain order matches emission order
-REP2 burst: 0 same-millisecond collisions among 10 events
-REP2 burst: drain order matches emission order
-```
-
-In-process emission costs more than a millisecond per event in both
-representations, so a realistic burst preserves order. But the wire format
-cannot *represent* sub-millisecond order: `list_dir` sorts by
-`(ts_ms, filename)` and the `<rand6>` suffix is random. Constructed
-deterministically in
-`same_millisecond_events_drain_by_random_suffix_not_emission_order`, two events
-sharing a millisecond drain in random-suffix order, not emission order. A
-higher-rate producer than this one would need a stronger ordering token.
-
-DING drains FIFO, one notice per delivery: `new_arrivals` yields the unread set
-in `(ts_ms, filename)` order and `flush_pending` works the front of a
-`VecDeque` with a single staged payload, popping only on `Delivered`.
-
-**Where "coalesce to latest per stream-key" would have to live.** Not in DING:
-`flush_pending` sees one notice at a time and holds exactly one staged payload,
-and the only place with the full unread set is the protected enqueue path.
-Adding a stream-key rule there would also mean DING deleting inbox items, which
-it deliberately does not do. The remaining place is the **producer**: archive
-the superseded item for the stream key before publishing the new one. Proven in
-`producer_side_supersede_collapses_a_stream_to_its_latest_event` — four CI
-transitions leave exactly one unread item (`success`) and three durable archived
-predecessors, because the archive receipt guarantees the superseded notices are
-not resurrected. This needs no new st2 concept, only a documented producer
-pattern.
-
-### 5. Provenance
-
-| Question | Rep 1 | Rep 2 |
-| --- | --- | --- |
-| Which producer? | `from:` frontmatter — but it is an Agent Spec identity, indistinguishable from a real agent | `from:` is the declared principal; `principals/` membership proves it is not an agent |
-| Which external event id? | `source:` / `event-id:` frontmatter, visible in `message read` and `message ls --json` | `tags.source` / `tags.event-id` inside the JSON envelope, via `st2 request read --json` |
-| Created vs deduplicated? | `--json` receipt: `{"status":"published","to":"h.worker","filename":"…","deduplicated":false,"idempotencyKey":"github:ci:pr-42#failure","source":"github:ci:pr-42","eventId":"failure"}` (spike addition) | `--json` receipt: `{"status":"published","idempotencyKey":"github:ci:pr-42#failure","filename":"…","deduplicated":false}` (already shipped) |
-| Receipt after the fact? | none — the producer must re-derive the key and re-send, or read `message sent --json` | `st2 request status --idempotency-key … --json` returns the tagged union `pending \| replied`, including the agent's reply body |
-| Readable without a decoder? | yes, ordinary markdown + `message read`/`ls`/`thread` | no, the body is an opaque JSON envelope |
-
-Proofs: `rep1_provenance_is_readable_frontmatter_on_an_ordinary_message`,
-`rep2_provenance_is_a_typed_envelope_plus_a_principal_side_receipt`.
-
-Rep 2's `status` channel is the only one that closes the loop: the test
-publishes an event, observes `pending`, has the agent `request reply`, and then
-reads `replied` with the agent's body. Rep 1 has no analogue keyed by event id.
-
-### MESSAGE-R11, measured
-
-Five events each way. `st2 message sent h.pipe-agent --json` reports 5 rows —
-Rep 1 writes one sender-owned Sent row per pipe event into the producer's
-ordinary Agent Sent history. The principal has no Agent Sent index at all and
-the command fails for it. Proof: `rep1_pollutes_agent_sent_history_but_rep2_does_not`.
-MESSAGE-R11 explicitly keeps request publication state out of Sent history; Rep 1
-puts machine ingress squarely inside it.
-
-### Cost
-
-Ten sequential in-process emissions
-(`report_sequential_emission_cost_of_each_representation`):
-
-```
-REP1 10 sequential in-process emissions: 58.2ms
-REP2 10 sequential in-process emissions: 70.9ms
-```
-
-Rep 2 is the slower of the two despite having no sender lock: it runs catalog
-discovery twice per publish (`resolve_principal` then `resolve_agent`) and
-hashes the state key. Rep 1's cost is an exclusive flock plus a hash-chain
-commit. The important structural difference is not the mean but the contention:
-Rep 1 serializes every pipe event through the producing agent's single
-`SentLock::exclusive` (MESSAGE-R08), so a chatty pipe competes with that agent's
-own outgoing messages. Rep 2 has no shared lock.
-
-## Comparison
-
-| Axis | Rep 1 — message path | Rep 2 — principal path |
-| --- | --- | --- |
-| Idempotency scope | `(canonical sender, canonical recipient, key)`, sender-owned ledger (MESSAGE-R07) | `(principal, key)` in the principal's `request-state/outgoing`; the recipient is validated but not part of the key |
-| Fan-out to several agents | works: the recipient is part of the key | **refused** — the second recipient collides; needs the recipient in the key |
-| Concurrent replay | one item, one filename (12 threads) | one item, one filename (12 threads) |
-| Post-archive replay | file never re-created; no re-notify | file re-linked, then shadowed and cleaned by the archive receipt; no re-notify |
-| Crash between reserve and publish | resumable pending intent | reserved filename + envelope, replay finishes the same publication |
-| Provenance | readable frontmatter on an ordinary message | typed JSON envelope + principal-side receipt |
-| Outcome channel | one-shot receipt only | `request status` → `pending \| replied`, with the agent's reply |
-| Authoring burden | producer must be a declared Agent Spec: roster row, presence, derived DING, doctor checks | three lines of KDL; no task, presence, persona, or authority |
-| Marker rendering | resolves to a real hierarchy glyph — machine traffic looks like a peer agent | `?`, the same glyph as "unknown/broken", with a `request <key>` subject |
-| Fit with MESSAGE-R11 | violates it: one Agent Sent row per pipe event | satisfies it by construction |
-| Fit with R10 / MESSAGE-A01 agent-only identity | breaks it: a non-agent producer must impersonate or become an agent | preserves it: a principal is explicitly not an Agent Spec identity |
-| Consumer ergonomics | `message ls/read/thread` work unchanged | needs `request read`; the body is opaque to ordinary message tooling |
-| CLI surface today | `st2 message send --source --event-id --json` (spike) | `st2 request send --idempotency-key --tag --json` (shipped) |
-
-## Recommendation
-
-**Adopt Rep 2, the principal path, as the ingress representation for pipes, and
-fix its notice.**
-
-The deciding evidence is not idempotency — both representations are
-exactly-once-safe under concurrent replay and neither re-notifies after archive.
-It is identity and separation, and both are executable:
-
-1. Rep 1 cannot express a non-agent producer at all
-   (`rep1_refuses_a_non_agent_sender_but_rep2_accepts_a_declared_principal`).
-   Every pipe would either impersonate an existing agent or inflate the roster
-   with fake agents that acquire presence, a derived DING sidecar, and doctor
-   health obligations. This is precisely what the service-principal transport was
-   introduced to avoid.
-2. Rep 1 writes machine ingress into the producer's Agent Sent history
-   (`rep1_pollutes_agent_sent_history_but_rep2_does_not`), which MESSAGE-R11
-   already rules out for typed requests. Pipes have the same character.
-
-Rep 2's weaknesses are all in presentation, and all fixable without touching
-delivery:
-
-- Let `request send` take an optional `--subject` (or derive one from a
-  well-known tag) so the notice carries the CI state instead of the key.
-- Give the DING marker a distinct glyph for a declared non-agent principal, so
-  `?` keeps meaning "unknown" rather than doubling as "machine".
-- Add `to` and an echo of the caller's tags to the request receipt so it is as
-  self-describing as the spike's message receipt.
-- Scope the request state key by `(principal, recipient, key)` so one event can
-  fan out to several agents, matching MESSAGE-R07.
-
-Keep the message path's spike additions only as a comparison artifact. The one
-piece worth keeping independently is the `SendOutcome`/`deduplicated` receipt:
-a keyed `message send` currently prints a filename and no outcome, so an
-ordinary agent retrying a keyed send cannot tell what happened either.
-
-For burst control, adopt **producer-side supersede** as a documented pattern
-rather than a DING feature: archive the previous item for the stream key before
-publishing the next. It is one extra CLI call, it keeps the superseded events as
-durable history, and the archive receipt already guarantees the retired notice
-cannot come back.
-
-## Frictions
-
-- **No principal-authoring CLI.** A principal is created by hand-writing
-  `principals/<host>/<identity>/principal.kdl` with content that must exactly
-  match its path. `st2 agent-author`-style tooling has no principal analogue, so
-  a Nix module or a human writes the file. Trivial to add, and its absence makes
-  Rep 2 look harder to adopt than it is.
-- **Hardcoded request subject.** `request::publish` bakes
-  `format!("request {idempotency_key}")` into `rendered_message`, which is part
-  of the durable publication record. It cannot be changed after the fact and it
-  is the only thing DING shows.
-- **The `?` marker is overloaded.** It means "unknown sender", "unreadable
-  catalog", and "broken supervisor chain" already; a principal makes it also
-  mean "legitimate machine producer".
-- **`message send` had no outcome.** Before this spike, a keyed retry and a
-  fresh send printed the same thing.
-- **`send_to_resolved_inbox` has 10 arguments** and grew an eleventh concept.
-  `Provenance` collapsed three of them; a real change should go further.
-- **Request receipts omit the recipient.** `PublishReceipt` has no `to`, so a
-  producer emitting to several agents cannot correlate receipts without tracking
-  its own call sites.
-- **Same-millisecond ordering is unrecoverable** in the frozen filename grammar.
-  Fine for a poller, not for a webhook fan-in.
-
-## Open questions for a human
-
-1. Should a pipe be a *declared* catalog object (`pipe "gh-ci" { … }`) that st2
-   supervises on a cadence, or does st2 stop at the ingress boundary and leave
-   scheduling to systemd/launchd? Issue #137 puts "declare and supervise a
-   recurring shell-driven source" in scope; this spike only proves the ingress
-   half, and the poller is driven externally.
-2. Is `(source, event-id)` the right event identity, or should the dedup key be
-   `(stream-key, revision)` so supersede is a first-class outcome rather than a
-   producer convention? The CI case wants "latest wins per PR"; the timer case
-   wants "one per day, never superseded". This also decides the fan-out shape:
-   is one event to three agents one operation with three deliveries, or three
-   operations? Rep 1 answers "three" by scoping the key to the recipient; Rep 2
-   currently answers "one" and then refuses the second delivery.
-3. Should the DING marker distinguish a declared principal from an unknown
-   sender, and if so with what glyph? This changes a string every agent sees.
-4. What retention rule applies to `request-state/outgoing` records after the
-   inbox message is archived? They are the only thing preventing a much later
-   replay from re-publishing, and nothing prunes them today.
-5. Does a pipe event deserve a reply channel at all? Rep 2 gives one for free
-   via `request status`; if pipes are fire-and-forget, that is unused machinery,
-   and if they are not, `pending | replied` may be too thin for a long-running
-   subscription.
-6. Should `st2 message send --json` and its `deduplicated` outcome ship
-   independently of pipes? It is a small, generally useful honesty fix.
-
-## Conclusion
-
-Both representations satisfy issue #137's exactly-once, concurrent-replay, and
-archive-receipt requirements. The message path fails on identity: it cannot
-carry a non-agent producer without inventing a fake agent, and it writes machine
-ingress into Agent Sent history that MESSAGE-R11 deliberately keeps out. The
-principal path preserves both boundaries and already ships a durable outcome
-channel; its only real defects are that the DING notice says `request <key>`
-instead of what happened, and that `?` is an overloaded marker. Pipes should be
-built on the service-principal transport, with a subject on the request and a
-distinct marker for declared machine producers.
-
-## VRS Impact
-
-None yet. This is a throwaway spike carrying no requirement, no ontology term,
-and no INVARIANTS entry. It is evidence for DQ1's executable-eval bar and for
-whether issue #137's ingress boundary belongs on `message send` or
-`request send`.
-
-## Reproduce
-
-```sh
-nix develop -c cargo test --test pipe_ingress -- --nocapture
-```
-
-16 tests, all green. Regression suites run alongside, covering the named
-INVARIANTS proofs that touch the message wire format: `--test message` (6),
-`--test message_cli` (17), `--test request_cli` (9), `--test invariants` (1),
-`--test doctor` (9), `--test run` (47), `--test pty` (5), `--test status_agents`
-(10), `--test predecessor_ding_migration` (3), and `cargo test --lib` (325).
-
-Pre-existing failures on this HEAD, reproduced on a clean stash and unrelated to
-this spike:
-
-- `tests/eval_run_e2e.rs::canonical_agents_freeze_the_admitted_route_across_post_boot_catalog_mutation`
-  — fails identically with the spike stashed.
-- `src/codex_app_server/tests.rs::runtime_owner_lock_is_nonblocking_and_released_on_close`
-  — flaky under parallel `cargo test --lib` when the machine is also compiling;
-  green in 4/4 subsequent full runs and green in isolation.
-- `tests/native_only.rs::tracked_product_surface_contains_only_native_names` —
-  tripped on the old launcher wording in `docs/vrs/spec.md`, a file this spike
-  never touched. The wording is now neutral.
-- `tests/native_only.rs::clean_path_supports_help_validate_env_and_doctor` —
-  spawns `/bin/sleep`, which does not exist on this NixOS host.
-- `cargo fmt --check` reports diffs in 43 files this spike never touched, so
-  formatting is not a gate here.

-# Pipes: declaration and lifecycle prototype
-
-Date: 2026-08-20
-
-Branch: `schickling/2026-08-20-pipes` · commits `6ca0163`, `15bea2a`, and this one.
-
-## Question
-
-A "pipe" lets an agent subscribe to external events (GitHub CI updates, timers)
-delivered over the existing message bus. This spike covers the **declaration and
-lifecycle** half only: how does the event SOURCE get declared, launched,
-supervised, and torn down? (A separate spike covers ingress.)
-
-Hypothesis: a `pipe "name" { ... }` node on an agent declaration lowers to a
-DERIVED exec companion task, exactly mirroring how the DING sidecar is
-generated, and thereby inherits restart policy, flapping/parking, suspend and
-retire teardown, and crash-loop surfacing for free.
-
-## Result
-
-**Confirmed, and cheaply.** The derived-companion coupling in `src/reconcile.rs`
-and `src/run.rs` keys on `Task::derived`, never on the name `"ding"`. Exactly two
-places in the whole codebase are name-scoped to DING:
-
-- `src/reconcile.rs:298` — the fail-closed "unsupported derived task" gate.
-- `crates/agent-spec/src/spec.rs:398` — `has_delivery_transport`, correctly
-  scoped so a pipe cannot claim a transport.

-integration. **No change to `src/run.rs`, `src/flapping.rs`, `src/park.rs`,

-## (b) Proof results
-
-Every claim below is a test that was run, not a reading of the code.
-
-### 4a — fresh agent launches with its pipe in one pass
-
-`tests/run.rs::fresh_compact_agent_launches_with_its_derived_pipe` — one
-`up_once` pass launches `["example-linux.demo", "example-linux.demo.ding", "example-linux.demo.pipe-gh-ci"]`
-and the pipe's launch is the exact late-bound argv:
-
-```
-<running st2> pipe run --agent example-linux.demo --name gh-ci --root <catalog> --command poll-gh-ci.sh
-```
-
-`ST_AGENT=example-linux.demo` is injected into the pipe like any other task (Runner-owned
-task identity holds).
-
-### 4b — suspend / retire / hold tear the pipe down
-
-- `retired_compact_agent_stops_agent_and_derived_pipe`
-- `suspended_compact_agent_stops_its_derived_pipe_without_touching_a_sibling`
-- `held_adopt_only_compact_agent_stops_its_live_derived_pipe`
-- `parked_compact_agent_stops_its_live_derived_pipe` (agent parks → pipe killed)
-- `selected_missing_derived_pipe_is_held_without_broadening_to_its_agent`
-
-### 4c — a crash-looping pipe parks WITHOUT affecting the agent, and surfaces
-
-`tests/run.rs::a_crash_looping_pipe_parks_and_surfaces_without_disturbing_its_agent`
-
-With `restart { attempts 1; mode "fail" }`, a live agent, a live ding, and a dead
-pipe, four `reconcile`/`execute` passes over ONE `FlappingCap` give:
-
-```
-report.flapping     == ["example-linux.demo.pipe-gh-ci"]
-lifecycle op log    == ["reap:example-linux.demo.pipe-gh-ci", "spawn:example-linux.demo.pipe-gh-ci"]
-crash_loops[0]      == { pty_id: "example-linux.demo.pipe-gh-ci", identity: "demo",
-                         supervisor: "cos-claude" }
-surfaced message    tags ["crash-loop"], body names example-linux.demo.pipe-gh-ci
-```
-
-**Measured caveat, not hidden:** the agent DOES appear in the raw runner op log,
-as `patch:example-linux.demo` — the pass's ordinary presentation batch, which touches every
-live task and carries no lifecycle meaning. The test filters `patch:` explicitly
-and says why. The first version of this test failed on exactly that line; the
-claim was narrowed rather than the evidence.
-
-`up_once` cannot express this case at all: both single-pass entry points build a
-fresh `FlappingCap`, so a one-shot reconcile can never park anything.
-
-### 4d — `st2 tasks --json` reports the pipe honestly
-
-`tests/task_inventory_cli.rs::a_derived_pipe_task_is_reported_honestly_alongside_its_agent`.
-Real CLI output against a live demo catalog:
-
-```json
-{"agent":"example-linux.demo","task":"pipe-gh-ci","runtimeId":"example-linux.demo.pipe-gh-ci",
- "kind":"exec","lifecycle":"service","retired":false,"desiredState":"running",
- "agentDesiredState":"running","agentDesiredStateReason":null,
- "runtime":{"state":"absent","pid":null,"createdAt":null,"generationId":null,"error":null},
- "parked":null}
-```
-
-No new field, no special case, no schema change. The inventory path runs the same
-`compile_generated_tasks` the supervisor does, so this also exercises the
-extended derived-task gate on the read-only diagnostic surface.
-
-### 5 — E2E with a fake GitHub CI poller
-
-`tests/pipe_e2e.rs` (11 tests) plus a hand-driven run of the real binary against
-a temp catalog. The poller is a shell script reading a local state file
-(`pending → running → success`), emitting one JSON line per transition with its
-own `id`. No network.
-
-Real CLI, first run:
-
-```
-$ st2 pipe run --agent example-linux.demo --name gh-ci --root $D --host example-linux \
-    --command "./poll-gh-ci.sh ci-state.txt"
-st2 pipe: 'gh-ci' source running → example-linux.demo's inbox (task example-linux.demo.pipe-gh-ci)
-st2 pipe: exiting (SourceExited) after 3 delivered event(s)
-$ ls $D/agents/example-linux/demo/resources/inbox/
-1787207698953-nhm7w0.md  1787207698957-he2enx.md  1787207698959-67fd1f.md
-```
-
-One delivered message:
-
-```
----
-from: example-linux.demo
-subject: pipe gh-ci: {"id":"run-7:pending","run":7,"state":"pending"}
-tags: pipe, pipe:gh-ci
-idempotency-key: pipe:gh-ci:id:run-7:pending
----
-x-st2-pipe-task: example-linux.demo.pipe-gh-ci
-
-{"id":"run-7:pending","run":7,"state":"pending"}
-```
-
-Second, identical run — the supervisor-restart case:
-
-```
-st2 pipe: exiting (SourceExited) after 3 delivered event(s)
-$ ls .../inbox | wc -l
-3
-```
-
-Zero new messages, and the receipts are byte-identical
-(`a_supervisor_restart_replays_the_source_without_duplicating_its_events`
-asserts the filenames match). After appending a `failure` transition, the same
-command produces 4 messages — the dedup is on event identity, not on "already
-ran".
-
-`killing the poller respects restart policy`:
-`a_dying_source_ends_the_run_instead_of_being_respawned_in_process` proves the
-runner RETURNS (`SourceExited`, status 9) with the pre-crash event preserved and
-no in-process respawn; the supervisor half is 4c above. There is deliberately no
-retry ladder inside `run_pipe` — a second lifecycle owner is exactly what this
-shape argues against.
-
-### Full-suite status
-
-`cargo test --workspace --no-fail-fast`, before and after, produces the
-**identical** failure set. Seven suites fail for pre-existing, environment-shaped
-reasons unrelated to pipes:
-
-| Suite | Test |
-|---|---|
-| `catalog_diff` | `classification_only_and_nested_agent_filename_changes_are_exact` |
-| `eval_run_e2e` | `canonical_agents_freeze_the_admitted_route_across_post_boot_catalog_mutation` |
-| `eval_up` | 4 tests |
-| `materialize` | `up_materialize_only_writes_the_overlay_without_needing_pty` |
-| `native_only` | `clean_path_supports_help_validate_env_and_doctor`, `tracked_product_surface_contains_only_native_names` (fails on a retired product name still present in `docs/vrs/spec.md`) |
-| `targeted_reconcile` | `targeted_once_real_pty_preserves_sibling_generation_across_selected_lifecycle` |
-| `task_inventory_cli` | `completed_catalog_aba_during_runtime_observation_is_incomplete` |
-
-Green and directly relevant: `--test run` (57), `--test pipe_e2e` (11),
-`-p agent-spec` (68), `--lib` (327), `--test invariants`, `--test reconcile`.

-## (c) The KDL grammar
-
-```kdl
-agent "demo" {
-  host "example-linux"
-  command "…"
-  ding
-
-  pipe "gh-ci" { command "gh run watch --json" }   // shell, under sh -c
-  pipe "tick"  { argv "tick-source" "--json" }     // direct, no shell
-}
-```
-
-The child set is deliberately two nodes. A pipe declares WHERE events come from.
-How it is supervised is inherited from the agent (`restart{}`, `desired-state`,
-`lifecycle`, `keep`); how events are delivered is the bus contract. Nothing else
-needed a knob.
-
-`pipe "<name>"` lowers to a derived exec task named `pipe-<name>` with runtime id
-`<host>.<identity>.pipe-<name>`.
-
-### Validation diagnostics
-
-Source-located, from `parse_declared_document` (these fail discovery, so an
-invalid pipe never becomes a runnable spec):
-
-| Code | Message |
-|---|---|
-| `task-name-missing` | `pipe task must have one positional string name` |
-| `pipe-launch-missing` | `pipe must declare exactly one of \`command\` or \`argv\`` |
-| `unsupported-pipe-interval` | ``pipe `every` is reserved for the future `schedule` contract; a pipe declares a long-running event source`` |
-
-Lowering-level refusals (anyhow, from `kdl_format` / `into_agent_spec`):

-| duplicate child | ``pipe 'gh-ci' has duplicate `command` `` |
-| unknown child | ``pipe 'gh-ci' has unsupported field `on-error` `` |
-| duplicate pipe | ``agent declares `pipe "gh-ci"` more than once`` |
-| bad name | `agent 'demo' pipe name 'GH_CI' must match [a-z0-9] ([a-z0-9-]*[a-z0-9])?` |
-| empty command | ``agent 'demo' pipe 'gh-ci' has an empty `command` `` |
-| name collision | ``agent 'demo' declares both `pipe "gh-ci"` and a task named `pipe-gh-ci`; choose one form`` |
-
-`st2 validate` on a catalog with three bad pipes:

-
-## (d) How well the derived-companion seam fit
-
-### Fit with no change at all
-
-- **Coupling.** `reconcile.rs:685` (a derived task is not launchable unless its
-  agent's session is alive) and `reconcile.rs:874` (an ineligible agent's derived
-  companions are stopped) are generic over `Task::derived`. Both directions of
-  the pipe⇄agent coupling worked on the first run.
-- **Parking and crash-loop surfacing.** `execute`'s `GaveUp` branch builds a
-  `CrashLoop` for ANY target, and only resets `agent_available` when the parked
-  target is the canonical agent. A parked pipe therefore surfaces and leaves its
-  agent alone with zero code change.
-- **`is_runnable`** (`spec.rs:388`) filters derived tasks, so a pipe-only
-  declaration is correctly `unrunnable`. Asserted
-  (`a_pipe_alone_does_not_make_an_agent_runnable`) rather than bent.
-- **`has_delivery_transport`** is name-scoped to `ding`, so a pipe cannot claim
-  one. Asserted (`a_pipe_does_not_claim_a_delivery_transport`).
-- **`st2 tasks --json`** wire shape: unchanged.
-- **GC / keep / targeted reconciliation:** unchanged.
-
-### What had to bend
-
-1. **The derived marker carries no payload.** DING needed none — its whole
-   invocation is derivable from the bus id. A pipe must carry the author's
-   command through lowering to reconcile. Rather than add a field to `Task`, the
-   payload rides in the **marker argv**, and reconcile asserts a fixed prefix
-   before rewriting argv[0] and the `$ST_ROOT` slot. This is the contract
-   `compile_driver_agent_tasks` already enforces on a driver expansion, so it is
-   a reuse rather than a new mechanism — but it means the `Task` model still
-   cannot describe a parameterized companion, and a third companion kind with
-   structured parameters would repeat this.
-
-2. **A task identity cannot be an idempotent bus sender.** This is the sharpest
-   friction found. `message::send_to_resolved_inbox` resolves the SENDER to a
-   catalog agent, because that agent's folder holds the sent-message idempotency
-   ledger. A pipe companion is a task, not an agent, so
-   `from = "example-linux.demo.pipe-gh-ci"` fails with *"no agent … found in catalog"*.
-   The only existing non-agent sender path (`message::send_to_inbox`, used by
-   `surface_crash_loop`) bypasses the ledger entirely and would forfeit
-   deduplication — the one property a pipe most needs.
-
-   Worked around by sending as the owning agent, with provenance in the tags and
-   an `x-st2-pipe-task:` body line. The visible cost is measured in
-   `a_pipe_event_pokes_the_agent_as_a_self_addressed_notice`: the agent reads
-
-   ```
-   [DING] ↺ example-linux.demo: pipe gh-ci: {"id":"run-7:success",…} [id:2f7b]
-   ```
-
-   The `↺` marker means "from myself" — precisely the wrong story for an external
-   event. See (f).
-
-3. **Task-name grammar had to be invented, not inherited.** There is no existing
-   task-name validation: `pty "…"` / `exec "…"` accept any string. Since a pipe
-   name becomes part of a runner-owned task name AND runtime id, this spike
-   imposes `[a-z0-9] ([a-z0-9-]*[a-z0-9])?`, ≤40 chars, plus an explicit collision
-   check against authored `pty`/`exec` names. Without the collision check, a
-   duplicate runtime id would only surface later as a `st2 tasks` error.
-
-4. **Startup grace is load-bearing, and was a real bug.** One pass launches the
-   agent PTY and its companions together, so a pipe routinely probes before the
-   pty registers its pidfile. A naive "owner not alive → exit" made a fresh pipe
-   exit instantly (observed on the demo catalog) and would have crash-looped it
-   into a park. Fixed by mirroring `ding::SessionWatch` exactly: never exit until
-   the owner has been seen alive once, then a 3-miss debounce
-   (`an_owner_that_has_not_registered_yet_does_not_end_the_run`).
-
-5. **Presentation patching is not lifecycle.** See 4c.
-
-### Inherited but NOT separately proven
-
-Stated so the derived-companion framing does not imply coverage it lacks. These
-enumerate `spec.tasks` and so should work, but this spike wrote no pipe-specific
-test for them:
-
-- `st2 doctor` retirement and suspension health predicates.
-- Final GC (`remove`) of a dead retired pipe record.
-- A **parked** pipe row through `st2 tasks --json` (parking is proven in
-  `tests/run.rs`, and a healthy inventory row is proven; the combination is not).
-
----
-
-## (e) Interactions with reserved `schedule`, and DQ1's four items
-
-### `schedule` (README ~274-290, `declared.rs`)
-
-`pipe` and `schedule` are independent nodes and neither absorbs the other; a
-document with both reports only the schedule's rejection
-(`a_pipe_and_the_reserved_schedule_node_are_independent_shapes`).
-
-The interesting decision is `every`. An optional `every "30s"` on a pipe was
-prototyped and then deliberately **rejected with its own diagnostic**. The
-reasoning: an interval turns a pipe into scheduled work, which is the reserved
-node's contract, and an interval-respawn loop inside `run_pipe` would make the
-sidecar a second lifecycle owner — the exact thing this shape argues against.
-
-The two concepts stay cleanly separable if `pipe` means *"a long-running process
-whose stdout is events"* and `schedule` means *"st2 runs this on a cadence"*. A
-polling source that wants a cadence should own its own sleep loop, or — better —
-`schedule` should eventually be able to target a pipe. **Interval-respawn mode
-was not implemented.** What it would take: a `PipeExit::SourceExited` that sleeps
-and re-spawns rather than returning, which is ~15 lines but re-opens the
-lifecycle-ownership question; the honest version is for the supervisor to grow a
-"restart after N seconds, not immediately" policy, which `restart { delay }`
-already almost expresses.
-
-### DQ1's four unspecified items
-
-- **KDL shape** — proposed and running (section c). Minimal: a name and one of
-  `command`/`argv`.
-- **Event inbox** — this spike uses the agent's ordinary inbox with `pipe` and
-  `pipe:<name>` tags. It works, and the measured cost is that pipe events queue
-  FIFO behind human and agent messages and consume the same DING budget. A
-  high-rate pipe would drown the inbox. Whether pipe events deserve a separate
-  box, or just a filter, is unresolved — but the `[DING]` frame carries **no
-  body**, only sender and subject, so *any* answer must put the signal in the
-  subject. That is why `summarize` exists.
-- **Deduplication boundary** — the sharpest finding. Two regimes, both proven:
-  - A source-supplied JSON `id` → key `pipe:<name>:id:<id>`. This is the source
-    declaring which occurrences are the same occurrence, and it is the right
-    boundary: replay dedups, genuinely new events land.
-  - No id → key `pipe:<name>:sha:<fnv1a>` over the trimmed line. This
-    **cannot distinguish** "the supervisor restarted us and the source replayed a
-    still-current state" (dedup wanted) from "the same event legitimately
-    happened twice" (dedup wrong). Demonstrated, not asserted:
-    `an_id_less_source_dedups_by_content_which_also_collapses_real_repeats` emits
-    `ci failed` twice from one run and gets **one** message.
-
-    So: **an event id is not a nicety, it is the contract.** A pipe whose source
-    cannot supply one has no sound dedup boundary. The design should probably
-    make `id` mandatory-by-declaration (a `pipe "x" { id-field "run_id" }` or
-    similar) rather than silently degrading.
-  - Keys are namespaced per pipe, so two pipes on one agent cannot collide.
-  - Key and body must derive from the SAME bytes, or a replay becomes a hard
-    "idempotency key reused with different content" error instead of a reused
-    receipt. This constrains the subject too (hence `summarize` being pure).
-- **Execution receipts** — partially free. The bus's own archive filename is
-  already a durable receipt, and the idempotency ledger in the sending agent's
-  folder is a second one. `PipeReport` additionally reports which lines were
-  in-run duplicates. What does NOT exist: any record of *how far the source got*
-  before it died. A restarted pipe re-reads its source from scratch and relies
-  entirely on dedup. For a poller that is correct; for a streaming source with a
-  cursor, it is not, and nothing here addresses a cursor.
-
----
-
-## (f) Frictions and recommended refactors
-
-1. **Let a declared task identity own a sender ledger.** The "no agent
-   'example-linux.demo.pipe-gh-ci'" failure is the one place the seam genuinely does not
-   reach. The mechanism already exists in a neighbouring shape — the *Idempotent
-   service requests* invariant describes "a declared non-agent service principal"
-   publishing one exact request per idempotency key. Extending that principal
-   notion to runner-owned task identities would let a pipe be its own sender,
-   which fixes the `↺` marker and makes provenance structural instead of a body
-   line. **This is the top recommendation.**
-
-2. **Give the derived-companion seam a payload.** Marker argv works and reuses an
-   established pattern, but a third parameterized companion would justify a typed
-   `Task::companion: Option<Companion>` and a single `compile_generated_companions`
-   with an exhaustive match.
-
-3. **Rename `compile_generated_ding_tasks`.** It now compiles two companion kinds
-   and holds the fail-closed gate for all of them. Left unrenamed here to keep
-   the spike diff legible.
-
-4. **Add task-name validation for authored `pty`/`exec` too.** The pipe path now
-   validates names; the authored path still does not, so `exec "a.b.c"` can
-   produce a confusing runtime id.
-
-5. **Make the event id declarable.** See DQ1 dedup above.
-
-6. **Consider whether `patch:` belongs in the runner op stream at all**, or
-   whether presentation should be a distinct trait — it made an otherwise clean
-   "nothing else was touched" assertion need an exception.
-
----
-
-## (g) Open questions only a human can settle
-
-1. **Who is the sender of an ingested external event?** The owning agent
-   (self-addressed, `↺`, works today), a per-pipe principal (needs the ledger
-   change in (f)(1)), or the runner `st2.<host>` (loses idempotency)? This is a
-   product question about what an agent should *read*, not a technical one.
-
-2. **Is a source-supplied event id mandatory?** Content-hash dedup is unsound in
-   a way that is invisible until it silently drops a real duplicate event.
-   Refusing a pipe that cannot declare an id is safer and more annoying.
-
-3. **Do pipe events belong in the agent's ordinary inbox?** They currently queue
-   FIFO against human messages and consume DING budget. A busy CI pipe will
-   change how an agent's inbox feels.
-
-4. **Should `schedule` be able to target a `pipe`,** or should `pipe` grow its own
-   cadence? This spike deliberately kept them apart, but a poller is the most
-   obvious pipe and pollers want cadence.
-
-5. **What happens to events while an agent is suspended?** Today the pipe is torn
-   down with the agent, so events during suspension are simply not observed —
-   there is no backfill. Correct for a live-CI feed, wrong for an audit trail.
-
-6. **Should a parked pipe be louder than a parked task?** A silently parked pipe
-   means the agent stops receiving a class of event with no local signal. The
-   crash-loop message goes to the *supervisor*, not to the agent whose eyes just
-   closed.
-
-## VRS Impact
-
-None yet — this is a spike. It supplies evidence toward DQ1 (KDL shape, event
-inbox, deduplication boundary, execution receipts) and adds no requirement,
-invariant, or ontology term. No INVARIANTS.md row was added: the derived-companion
-lifecycle row already covers what the pipe inherits, and this spike introduces no
-new load-bearing guarantee of its own.
-
-## Method
-
-E2e prototype in an isolated worktree of `main` (8ff140e): parse a nested
-`pipe` declaration, lower it to a derived exec companion through the DING
-seam, implement a supervising runner and emit path, then prove lifecycle
-behavior by extending the derived-DING test fixtures — §(a)–§(g) document the
-build, proofs, grammar, seam fit, and frictions; 27 new tests plus the eleven
-named derived-DING lifecycle tests.
-
-## Conclusion
-
-The derived-companion seam carries stream sources with no changes to run,
-flapping, park, or task inventory — the hypothesis holds cheaply. The two
-findings that outlived the prototype: a task identity cannot be an idempotent
-bus sender (the self-send workaround renders `↺` for an external event), and
-a producer-supplied event id is the dedup contract (content hashes cannot
-distinguish replay from repeat). Decisions 0004/0005-streams-are-agent-nested-and-stream-named supersede this
-prototype's `pipe` naming and self-send emit path; its lifecycle proofs and
-KDL shape carry forward into STREAM-R01 and STREAM-R08.

-# Stream request-retirement and ring-bound plan
-
-Date: 2026-10-07
-
-Status: plan; no replacement proof or ring measurement is claimed here.
-
-This plan resolves the work needed for [DQ-S1, DQ-S3, and DQ-S4](../open-questions.md), without changing their unresolved status. The accepted direction is [decision 0004](../../.decisions/0004-stream-events-are-a-distinct-record-kind.md): typed service-principal requests are absorbed by stream events and ordinary `message reply`; reply status derives from `in-reply-to`. Retirement is conditional on a routable producer endpoint and proof, not on the decision alone (decision 0004, lines 57–62).
-
-## A. Typed request/reply retirement
-
-`src/request.rs` defines `RequestEnvelope`, `ReplyEnvelope`, and `PublicationRecord` with `deny_unknown_fields` (`src/request.rs`, lines 38–71). Do not extend these wire types or migrate their deduplication receipts. The accepted consequence is a fresh event/message namespace and retirement of request receipts, not an in-place wire migration (decision 0004, lines 91–96). The current **Idempotent service requests** invariant still names `tests/request_cli.rs` and remains load-bearing until replaced (`docs/vrs/.delta/DELTA-002-typed-request-absorption-pending.md`, lines 28–36).
-
-| Gate | Required work and proof | Exit condition |
-| --- | --- | --- |
-| 0. Keep compatibility intact | Leave `src/request.rs`, the `st2 request` surface, its request-state behavior, and the current invariant row unchanged while any later gate is incomplete. | No deprecation starts before every following prerequisite is met. |
-| 1. Prove stream transport | Keep/add stream-ingress proofs for stable identity, concurrent/crash replay, changed-identity conflict, declared-recipient/fan-out behavior, and bounded retention. Existing ingress proofs include `tests/event_e2e.rs::stable_event_identity_publishes_exactly_one_canonical_message`, `::concurrent_replays_publish_exactly_one_event`, `::conflicting_reuse_and_undeclared_or_suspended_ingress_fail_closed`, and `::stream_state_is_bounded_and_forgets_only_beyond_its_honest_horizon`. | Replacement event publication guarantees are covered independently of the old request transport. |
-| 2. Prove the reply endpoint (DQ-S1) | Define how an event's producer identity resolves to an authorized, real mailbox; a `<host>.<agent>/<stream>` `from` value alone is not a reply recipient. Add an end-to-end proof that an eval-owned external requester emits an event, the intended agent replies with ordinary `message reply`, and the reply is delivered to that requester's routable endpoint without an orphan mailbox or Agent Spec identity. Prove unknown/ambiguous endpoints and impersonation fail closed. | The endpoint is usable end to end by the external requester, preserving the compatibility capability in `MESSAGE-A01`; a grammar-only change is insufficient. |
-| 3. Prove reply-derived status | Prove status is `pending` until an ordinary reply with the event's `in-reply-to` exists, then `replied` with that reply's sender/tags/body. Include missing, duplicate, and unrelated replies as applicable to the defined status contract. The status is derived from the ordinary message relation, not a second typed reply envelope (decision 0004, lines 57–60). | Callers can determine completion and retrieve the reply without `request-state/replies/`. |
-| 4. Re-point invariant and start deprecation atomically | In one commit, replace the **Idempotent service requests** row's proof references with the complete stream publish + routable-reply + derived-status proof set, and announce the `st2 request` deprecation window. Keep the invariant-reference checker green. This ordering is required by the open drift record (`docs/vrs/.delta/DELTA-002-typed-request-absorption-pending.md`, lines 44–49). | The invariant no longer claims the typed path is the sole evidence, and users have a published migration window. |
-| 5. Complete the window, then cut over | Keep the deprecated request entry points and explicit migration guidance available for one full release after the deprecation announcement. At the window's end, remove the request module/CLI and its request-state reads/writes; do not convert old receipts. Existing inbox records remain ordinary messages: users can read and reply through message commands. Delete the superseded typed-request spec sections, retain their forward pointers until the removal commit, and reword `MESSAGE-R11` to its surviving guarantee. Record the exact removal commit when closing DELTA-002. | No typed request wire reader/writer remains; no unsupported receipt migration is implied. |
-
-If Gate 2 or 3 fails, stop the retirement sequence and keep the typed path and invariant row in force. The deprecation clock begins only at Gate 4, never when a plan or endpoint design is merged.
-
-## B. Measure the stream receipt-ring bound (DQ-S3, STREAM-R04/R05)
-
-The ring is the entire event-identity deduplication, conflicting-content-detection, and supersession-lookup horizon; an evicted identity is accepted as new without inbox/archive history scans (STREAM-R04/R05; `docs/vrs/04-stream/spec.md`, lines 172–186 and 263–267). Therefore evaluate K as a correctness horizon, not merely a cache hit-rate or speed setting. `128` is implemented but not yet measured (`docs/vrs/04-stream/spec.md`, lines 263–265).
-
-### Collection protocol
-
-1. **Choose representative sources and scope.** Collect per-stream, per-recipient observations from real adapter workloads covering CI transitions, build events, and timer sources. Include quiet periods, normal activity, bursts, retries, rediscovery after adapter restart, and delayed delivery/retry behavior. Record the observation interval and workload identity without recording event payloads or secrets.
-2. **Capture the minimum fields.** For each attempted emit record a stable `(stream, event-id)` (or a privacy-preserving stable token), first-seen time, every retry/rediscovery time, whether the retry was a duplicate or a new identity, a fingerprint of the full rendered event content, the `key`, supersession intent (including the selected predecessor identity when present), and the count of distinct event IDs admitted between the original event and its last retry. Also capture burst rate and event ordering. The fingerprint must distinguish changed rendered content without retaining payloads or secrets; do not infer the retry horizon from average emit rate alone.
-3. **Cover tail behavior.** Run collection long enough to include the longest known retry/rediscovery schedule and representative source restarts; document gaps, censored retries, and any source whose retry policy is unknown. Separate observed maximum from percentile summaries; do not claim a finite guarantee from a sample that did not cover the relevant retry window.
-4. **Replay against candidate K values.** For each captured sequence, simulate the current FIFO receipt-ring semantics using event identity, rendered-content fingerprint, key, supersession intent, and selected predecessor. Report (a) distinct newer identities admitted before each retry, (b) whether that retry remains inside the ring, (c) which duplicate, conflicting-content, changed-key, or changed-supersession decisions differ after eviction, and (d) maximum resident receipt count/state bytes. Include the implemented K=128 and candidate alternatives. Do not consult inbox/archive history in the simulation: that would violate the intended boundary.
-5. **Check the decision threshold.** State the operational retry/rediscovery window the product intends to cover. To claim that a candidate K covers it, it must retain every identity through the last retry in the collected in-scope traces, with any uncaptured or unbounded retry policy explicitly listed as a limitation. If 128 fails, quantify the smallest fixed ring that covers the chosen window and its state cost; consider another bounded index only if a fixed ring is materially impractical. If 128 covers traces, retain it only with the observed workload, coverage limits, and the chosen safety margin documented.
-6. **Publish evidence and resolve.** Add a results entry to this experiment plan (or a dated companion `.experiments/` report) with source/workload, collection dates, sample counts, retry-window coverage, replay method, measured maxima/distribution, state-size impact, limitations, and recommendation. Resolve DQ-S3 only after this report justifies keeping 128, changing K, or replacing the ring with a named bounded structure. Then update the spec's K statement and this question's status in the same documentation change.
-
-### Required report table
-
-| Source class | Observation window | Events / retries | Longest retry or rediscovery span | Max distinct newer IDs before retry | K=128 duplicate/conflict decision changes | Candidate K / bounded alternative | Limitations |

-These rows are an empty reporting template, not measurement results. A future conclusion must tie the selected bound to STREAM-R04's retry identity behavior and STREAM-R05's constant-size, history-independent state guarantee.

-# Stream open questions
-
-Each entry links a spec `DQ-S*`. Questions leave this file when resolved —
-into [spec.md](./spec.md) as decisions or [`.experiments/`](./.experiments/)
-as tested hypotheses.
-
-- **DQ-S1 Producer reply routing.** Events use `<host>.<agent>/<stream>` as
-  their producer identity, but that subordinate identity does not currently
-  resolve as an agent or service-principal mailbox for an ordinary
-  `message reply`. Resolves by: specifying a real reply recipient with an
-  end-to-end proof. Typed request retirement remains blocked until the
-  eval-owned external requester has that working path. See the staged gates
-  in [the retirement and ring-bound plan](./.experiments/2026-10-07-retirement-and-ring-bound-plan.md#a-typed-requestreply-retirement).
-- **DQ-S3 Ring bound and identity horizon.** `K = 128` is the implemented
-  deduplication and conflicting-content-detection horizon, not merely a fast
-  path: an evicted identity is accepted as new, without scanning inbox or
-  archive history. That is no longer a divergence: ratified STREAM-R04/R05 and
-  decision 0004 both say the retained receipt ring is the idempotency boundary
-  and that an archive receipt keeps its authority for a known filename without
-  being an event-identity index. What stays open is only the *value*: `128` is
-  unmeasured. Resolves by: measuring real adapter emit rates and
-  retry/rediscovery windows (CI transitions, builds, timer sources), then
-  keeping the bound, raising it, or choosing a different bounded index. Use the
-  collection and replay protocol in [the plan](./.experiments/2026-10-07-retirement-and-ring-bound-plan.md#b-measure-the-stream-receipt-ring-bound-dq-s3-stream-r04r05).
-- **DQ-S4 Request absorption staging.** The typed request/reply envelopes
-  (`request.rs`) are absorbed by events + ordinary replies (decision 0004),
-  but its wire types carry `deny_unknown_fields` and its invariant row names
-  live tests. Resolves by: a staged plan — land replacement proofs including
-  the routable reply endpoint from DQ-S1, re-point the invariant row, retire
-  the module behind a deprecation window; blocked until both the stream
-  implementation and that reply path are merged. The required proof gates,
-  atomic invariant re-pointing, and release-length window are in [the plan](./.experiments/2026-10-07-retirement-and-ring-bound-plan.md#a-typed-requestreply-retirement).
-- **DQ-S5 Top-level shared streams.** One adapter feeding many agents
-  (STREAM-T02). Must be defined as a generalization: a nested stream is a
-  top-level stream whose owner and sole recipient is the enclosing agent.
-  Blocked on: real demand — two catalogs actually duplicating an adapter.
-- **DQ-S6 Parked-stream owner notification.** A crash-looping stream parks and
-  surfaces to the declared supervisor; the owning agent — whose eyes just
-  closed — learns nothing. Should the owner also receive one event/notice?
-  Resolves by: operating v1; if agents act on stale world-views because a
-  stream died silently, the answer is yes.
-- **DQ-S7 Event body bounds.** Issue #238 wants bounded inbox bodies for
-  one-inference DING handling; the DING frame carries no body, so an event's
-  subject is the entire wake-time signal. st2 enforces a 1,000-byte subject
-  ceiling but currently no body ceiling. Resolves with #238's outcome; until
-  then adapters keep subjects self-sufficient and impose a small explicit body
-  bound rather than attaching unbounded provider/build logs.
-- **DQ-S8 One-shot stream completion.** The task model has no run-to-completion
-  lifecycle (`TaskLifecycle` is `Service | AdoptOnly`), so a wait-adapter that
-  exits after its terminal event relaunches, flaps, and parks — a fault report
-  for a successful wait. The accepted doctrine (spec: "Waits are standing
-  feeds") makes this the rare residual case: common waits ride standing keyed
-  feeds like `pty-lifecycle-watch`. If completion semantics are ever needed,
-  they belong in the task model (`TaskLifecycle`/`JobType`, adjacent to root
-  DQ1's scheduled exec work), not as a stream-level flag. Blocked on: real
-  demand — an agent whose one-off custom waits are frequent enough that
-  add/rm plus a kept-alive adapter measurably hurts.

-# Stream requirements
-
-## Context
-
-This subsystem defines declared event streams: named agent-owned subscriptions
-that turn external-world changes into durable, deduplicated inbox events,
-waking the agent through the existing delivery transports. It refines root
-requirement [`R05`](../requirements.md) for inbox delivery, [`R22`](../requirements.md)
-for named declared subscriptions ("do not replace the schedule with repeated
-messages or polls" — a stream is the declared name a poll hides behind), and
-inherits immutable agent ID and mutable address semantics from `R19` and `R24`.
-Ordinary messages remain owned by
-[`03-message/requirements.md`](../03-message/requirements.md); terminal
-delivery remains owned by [`01-ding/requirements.md`](../01-ding/requirements.md).
-The record-kind and locality decisions are recorded in
-[`.decisions/0004`](../.decisions/0004-stream-events-are-a-distinct-record-kind.md)
-and [`.decisions/0005`](../.decisions/0005-streams-are-agent-nested-and-stream-named.md);
-executable evidence lives in [`.experiments/`](./.experiments/).
-
-## Assumptions
-
-- **STREAM-A01 Host-local streams:** A stream runs on its owning agent's
-  declared host (`R03`). Cross-host observation is served by placing the
-  adapter on the right host, not by remote streams. Ingress executes only in
-  that owner's local lock domain: the declaration's resolved logical host must
-  match a machine-local catalog/host binding established by the active
-  supervisor. The binding is not synchronized and records the local catalog
-  lock identity; caller-controlled logical `--host` cannot create it. A
-  synchronized remote catalog copy is not publication authority.
-- **STREAM-A02 Trusted producers:** Emitting into a declared stream is gated
-  by the declaration's existence and the trusted-fleet model (root `A02`), not
-  by authentication. An external producer that names an undeclared stream is
-  refused.
-- **STREAM-A03 World logic stays outside:** Adapters (GitHub pollers, timers,
-  monitoring bridges) are host tooling packaged outside st2; st2 carries no
-  HTTP client, scheduler, or provider-specific event logic.
-
-## Acceptable Tradeoffs
-
-- **STREAM-T01 No catch-up:** A restarted or resumed stream has no cursor; it
-  re-observes current state and leans on event dedup. Missed intermediate
-  transitions are not reconstructed.
-- **STREAM-T02 Per-subscriber adapters:** Two agents watching the same feed
-  run two adapter processes. A shared top-level stream form is future work and
-  must be a generalization of the nested form, not a second mechanism.
-- **STREAM-T03 No declared cadence:** v1 ships no `every`; a periodic source
-  is a long-running adapter that sleeps and emits. Declared cadence, if it
-  ever arrives, extends restart policy rather than adding an in-process loop.
-
-## Requirements
-
-### Must be a declared subscription
-
-- **STREAM-R01 Declared streams:** An agent declares zero or more named
-  streams. A stream exists iff declared. A stream with exactly one adapter
-  form — `command` or `argv` — lowers to one derived exec companion (the
-  stream task) that supervises the adapter; only a stream with neither form is
-  an external ingress endpoint. Stream names follow the task-name grammar and
-  are unique per agent alongside task names.
-- **STREAM-R02 Self-authoring:** An agent adds or removes its own streams by
-  editing its own declaration through the serialized catalog-authoring path,
-  under the same authority boundary as presentation authoring (`R25`). Add
-  exposes mutually exclusive shell `--command <shell>` and direct non-empty
-  `-- <program> [<arg>...]` argv forms, or neither for external ingress, while
-  preserving unrelated source bytes and the exact authored launch values. To
-  remove an adapter-bearing stream, the serialized path identifies its exact
-  derived runtime, stops/retires it, and durably confirms process absence
-  before publishing declaration removal. Failure before that source publish
-  leaves the declaration intact; adapter-less external ingress has no runtime
-  teardown. Direct manual KDL edits are outside this guarantee.
-
-### Must ingest exactly once
-
-- **STREAM-R03 Mandatory event identity:** Every emit names the target agent,
-  a declared stream, and a producer-supplied `event-id`. Emits without an
-  `event-id` are refused. Dedup scope is `(stream, event-id)` per recipient.
-  Admission and publication linearize while holding the catalog-authoring lock
-  across strict declaration/desired-state revalidation and the stream-state
-  transaction; lock order is catalog-authoring then stream state. This
-  linearization exists only in the recipient owner's host-local lock domain;
-  remote callers are refused before publication.
-- **STREAM-R04 Idempotent ingress:** One external event becomes exactly one
-  durable inbox record while its identity remains in the stream's retained
-  receipt ring. Replaying an `event-id` within that horizon — including
-  concurrent and crash-interrupted retries — returns the original filename,
-  creates no second record, and never re-notifies only when content, key,
-  supersession intent, and the originally selected predecessor semantics all
-  match. Reuse with changed intent is a conflict, not deduplication. Once
-  evicted, the identity is honestly accepted as new; an archive receipt
-  retains its existing authority for a known filename but is not an
-  event-identity index. The machine receipt distinguishes `created` from
-  `deduplicated`.
-- **STREAM-R05 Bounded stream state:** Per-stream durable dedup state is
-  constant-size: a bounded receipt ring plus one in-flight publication
-  reservation, including at most one selected predecessor receipt. The ring
-  defines the deduplication,
-  conflicting-content-detection, and supersession-lookup horizon. Event
-  publication does not write the Agent Sent ledger and performs
-  history-independent work per emit: it never scans inbox or archive history
-  to recover an evicted event identity or predecessor. A later emit
-  reconciles an abandoned reservation by validating its chosen file and
-  completing its stored compaction intent against the predecessor's retained
-  receipt. Absence from the inbox proves completion only through an
-  authenticated same-name archive receipt; absence from both fails closed.
-  Recovery does not require the producer to replay stale state and never
-  archives unvalidated bytes.
-
-### Must deliver as ordinary inbox work
-
-- **STREAM-R06 Ordinary transport:** An event is an ordinary inbox record
-  carrying event frontmatter (producing stream, `event-id`, optional `key`).
-  Delivery rides the unchanged inbox paths; DING renders events with the `»`
-  marker and inherits every fail-closed guarantee untouched.
-- **STREAM-R07 Producer-side supersession:** An emit may declare supersession:
-  the successor publishes before the newest still-unread matching predecessor
-  among the stream's retained receipts is archived (`key` scopes the match;
-  absent `key`, the whole stream does). Still-unread requires an inbox file and
-  no same-name archive receipt. Immediately before either the initial or a
-  recovered archive move, the predecessor's no-follow regular bytes and
-  parsed event identity must match its retained receipt, and the move must be
-  bound to that validated inode rather than re-resolving a replaceable
-  pathname. Any inability to prove or move that exact object fails closed
-  while preserving the inbox wake. A crash between those steps may leave both
-  events unread but never removes the only wakeup; the selected predecessor
-  filename and identity are retained in both pending and final receipts so
-  recovery and replay preserve that exact compaction semantics. Supersession
-  never touches DING staged ownership — a staged notice is released only
-  through the existing archive-receipt rule — and a fast-superseding stream
-  stays within `R15` bounds.
-
-### Must couple to the owning agent's lifecycle
-
-- **STREAM-R08 Companion lifecycle:** The stream task launches with its agent
-  and is stopped while the agent is held, suspended, retired, or terminally
-  parked, under the existing derived-companion contract. A crash-looping
-  adapter parks the stream task without disturbing its agent and surfaces to
-  the declared supervisor. Public `stream rm` holds catalog and exact-runtime
-  lifecycle serialization across stop confirmation and declaration commit, so
-  no reconcile pass can relaunch the adapter in between and no removed stream
-  leaves an orphan process.
-- **STREAM-R09 Suspension means eyes closed:** While an agent is suspended no
-  events accumulate for it. Resume re-observes current state; re-emitting
-  still-current state is safe under `STREAM-R03` dedup. Suspension and stream
-  removal serialize with owner-local emit through the catalog-authoring lock:
-  whichever owns it first is the linearized operation, and no emit admitted
-  after the lifecycle/catalog change can publish under stale eligibility.
-  This guarantee is scoped to the owner's local lock domain; cross-host
-  producers must forward to an owner-host adapter/transport before ingress.
-
-## Evidence
-
-Four executable records in [`.experiments/`](./.experiments/): the ingress
-comparison, the lifecycle spike, and the two design-pole explorations
-(unification vs differentiation), each with the tests it ran and the
-pre-existing failure set it verified against baseline.

-# Stream specification
-
-This document specifies declared event streams. It builds on
-[requirements.md](./requirements.md). Terminal delivery remains in
-[`01-ding/spec.md`](../01-ding/spec.md); ordinary messages remain in
-[`03-message/spec.md`](../03-message/spec.md).
-
-## Status
-
-Draft. The shapes below are the interview-settled design over the executable
-prototypes in [`.experiments/`](./.experiments/); field names and on-disk
-layouts may still move during implementation, the open questions are tracked
-in [open-questions.md](./open-questions.md).
-
-Immutable owner IDs, ID-keyed ingress, and derived task IDs are the accepted
-target. The current examples and implementation retain bus-identity ownership
-until [DELTA-003](../.delta/DELTA-003-agent-address-not-implemented.md) closes.
-
-## Scope
-
-This specification defines the `stream` declaration, its lowering to a derived
-companion, the `st2 event emit` ingress boundary, the event record and its
-frontmatter, per-stream dedup state, and supersession. It does not define
-scheduled work (the reserved `schedule` node, root spec DQ1), message
-threading (issue #49), or the staged retirement of the typed request/reply
-envelopes (tracked as a DQ below).

-```
-
-## Declaration and lowering (STREAM-R01, STREAM-R08)
-
-```kdl
-agent "demo" {
-  stream "gh-ci" {
-    command "gh-ci-watch --repo compoundingtech/st2"
-  }
-  stream "tick" {
-    argv "tick-source" "--daily"
-  }
-  stream "webhook" {}
-}
-```
-
-Exactly one of `command` (runs under `sh -c`) or `argv`, or neither (external
-ingress endpoint). No other children in v1; `every` remains rejected with its
-own diagnostic (STREAM-T03). Stream names are lowercase ASCII alphanumerics
-and inner hyphens, starting and ending alphanumeric, and share the per-agent
-uniqueness space with task names; `stream "x"` and a task named `stream-x`
-collide at validation.
-
-A stream bearing either adapter form (`command` or `argv`) lowers to one
-derived exec task named `stream-<name>`, synthesized beside the derived DING
-through the same seam and late-bound to the running st2 binary each reconcile
-pass. A stream with neither form is external ingress and has no companion. The
-derived task inherits the companion contract unchanged: launch with the
-agent's canonical task, stop while held/suspended/retired/parked, its own
-restart accounting, crash surfacing to the supervisor. The adapter process
-calls `st2 event emit` itself; there is no line-protocol runner in between.
-
-## Ingress boundary (STREAM-R03, STREAM-R04)
-
-```text
-st2 event emit [<recipient-address>]
-  [--id <recipient-agent-id>] # exact; mutually exclusive with address
-  --stream <name>             # must be declared on the recipient
-  --event-id <id>             # mandatory, producer-supplied
-  [--key <key>]               # grouping axis for supersession
-  [--supersede]               # archive unread predecessor for (stream, key)
-  [--subject <line>]
-  [--json]                    # receipt: recipient ID, filename, created|deduplicated
-  [body on stdin]
-```
-
-The address form uses the root bare-or-qualified algorithm. `--id` uses exact
-immutable-ID lookup and never falls through to address parsing.
-
-Emitting to an undeclared stream or unknown agent is refused before writes,
-and so is a recipient whose desired state is not running — suspension means
-eyes closed for external producers too (STREAM-R09): the emit returns a typed
-refusal rather than accumulating events a suspended agent will wake to.
-
-Ingress is owner-host-local. During strict discovery, the recipient
-declaration's resolved logical host must match an active machine-local owner
-binding established by `st2 up`/the supervisor for this catalog. The binding
-lives in the unsynchronized machine-local runner-state root, is keyed by a
-canonical catalog identity plus logical host, and records the local persistent
-catalog-authoring-lock `(device, inode)` and supervisor scope/generation. A
-derived adapter inherits this binding/capability. An external owner-local
-producer resolves the same machine-local record.
-
-Ingress opens the selected catalog lock and requires its identity plus the
-resolved logical owner host to match that binding before admission.
-`MsgCtx --host` may choose the logical bus label, including a supported alias that
-differs from the OS hostname, but cannot establish or replace the binding. A
-remote synchronized checkout has a different lock inode and no matching local
-supervisor binding, so `event emit --host <owner>` there refuses before stream
-state or inbox/archive writes. Stale/missing binding, supervisor-generation
-mismatch, or catalog relocation fails closed. A cross-host producer must
-forward its observation to an adapter or transport endpoint in the bound owner
-domain; that forwarding transport is not implemented by this subsystem.
-
-In the bound owner domain, emit acquires the same local catalog-authoring lock
-used by stream add/remove and desired-state edits, then performs strict catalog
-discovery and eligibility validation while holding it. It retains that lock
-across the entire per-stream transaction — pending reconciliation,
-reservation, inbox/archive work, and receipt finalization. The local lock order
-is catalog-authoring then stream state (then the ordinary message-box locks);
-no path may acquire them in reverse. Thus owner-local emit and
-removal/suspension have one linearization order: an authoring change that wins
-the lock is visible to admission, while an emit that wins first completes
-before that change commits. No cross-host POSIX-lock claim is made.
-
-Replaying `(stream, event-id)` — concurrently or across a crash — returns the
-original filename with `deduplicated` while that identity remains in the
-stream's retained receipt ring. Conflicting reuse with different content
-fails within the same horizon. Once an identity is evicted, ingress honestly
-treats it as new; inbox and archive files are not searched as an unbounded
-secondary index. An archive receipt keeps its `03-message` authority for a
-known filename, so crash recovery never restores that filename to the inbox.
-
-## Event record (STREAM-R06)
-
-An event is an ordinary inbox file (`<unix-ms>-<rand6>.md`, same directories,
-same archive semantics) whose frontmatter carries the event keys:
-
-```markdown
----
-from: dev3.demo/gh-ci
-stream: gh-ci
-event-id: run-812
-key: pr-42
-subject: 'CI: failure on PR #42'
----
-{"conclusion":"failure","run":812,"pr":42}
-```
-
-`parse_message` ignores unknown frontmatter keys, so old readers see a normal
-message; new readers classify on the presence of `stream` + `event-id`. The
-exact `from` grammar for a nested stream's producer identity is DQ-S1.
-
-PING renders events as `[PING] » <from>: <subject> [id:…]` — the `»` marker is
-the only PING change; classification, staged ownership, retries, and presence
-gating are inherited.
-
-## Stream state (STREAM-R05)
-
-Per-stream durable state is one constant-size record under the owning agent's
-resources (exact path DQ-S2): a ring of the last `K`
-`(event-id → filename, key, content digest, supersede, predecessor)` receipts
-plus a single in-flight publication reservation. Both forms bind the new
-event's identity, filename, key, full rendered-content digest, supersession
-intent, and the exact selected predecessor receipt (or explicit none). The
-ring is the entire deduplication,
-conflicting-content-detection, and supersession-lookup horizon: a replay hit
-answers in O(1) only if the rendered digest, key, and supersession intent match
-the retained receipt. Its stored predecessor selection is authoritative and
-is not recomputed on replay. A changed `--supersede` value is conflicting
-identity reuse, not a silent deduplication. A miss is accepted as a new
-identity without scanning the unread inbox or archive.
-
-Under the per-stream lock, every emit first reconciles an existing
-reservation. If its chosen filename exists as a no-follow regular file in the
-inbox or archive, recovery parses the event and requires its `stream`,
-`event-id`, and optional `key` to equal the reservation and its full rendered
-bytes to match the reserved SHA-256. Any mismatch or non-regular path fails
-closed without changing state. If the file exists in neither location, the
-unpublished reservation is abandoned and cleared.
-
-For a valid materialized reservation with supersession intent, recovery next
-completes the stored predecessor move. The stored filename must resolve to its
-retained ring receipt; that receipt, not newer stream state, is the validation
-authority. If a same-name archive file exists, recovery requires it to be a
-no-follow regular file whose parsed `stream`, `event-id`, optional `key`, and
-full rendered SHA-256 equal that receipt; only that authenticated archive
-receipt proves the compaction already completed. Otherwise the predecessor
-must still be a no-follow regular inbox file with the same verified identity
-and bytes, and recovery archives it. Absence from both inbox and archive,
-missing retained receipt, non-regular paths, or any identity/digest mismatch
-fails closed without advancing state. Only then are the successor's stored
-identity, filename, key, and digest promoted to the retained receipt ring and
-the reservation cleared. The current event is evaluated against the resulting
-ring afterward. Neither producer replay nor retained payload bytes are
-required to unblock the stream.
-
-For a new identity, emit persists a reservation with its identity, chosen
-filename, key, content digest, supersession intent, and the exact predecessor
-receipt selected from the bounded ring (when superseding). Candidate selection
-requires the predecessor filename to be present as a no-follow regular inbox
-file and absent from the archive. Emit then materializes the successor and,
-immediately before moving
-the stored predecessor, validates its current parsed `stream`, `event-id`, and
-optional `key` plus full rendered SHA-256 against that retained receipt — the
-same rule recovery uses. A mismatch or changed path shape fails closed. Only
-after validation does emit archive the predecessor and atomically clear the
-reservation while inserting the successor receipt. A crash before
-materialization leaves a safely abandonable intent; a crash afterward leaves
-validated bytes plus the exact compaction target needed to finish on the next
-emit. This prevents an unrecorded inbox file, a receipt for unrelated bytes,
-and abandoned or misdirected supersession while adding only one bounded state
-slot.
-
-### Filesystem publication protocol
-
-All file operations are relative to already-open, no-follow inbox/archive
-directory capabilities. Predecessor validation opens the source with
-`openat(..., O_NOFOLLOW)`, requires a regular file, parses and hashes bytes
-from that descriptor, and records its `(device, inode)` identity. The archive
-operation must bind the destination to that exact open object without a second
-unprotected pathname lookup (for example, capability-relative no-replace
-linking from the open descriptor). If the platform cannot link from an open
-descriptor, every box pathname mutator must share one exclusive mutation lock
-and `fstatat` must prove the source still has the validated `(device, inode)`
-immediately before a capability-relative no-replace link/rename. An
-uncooperative replacement, unsupported exact-object primitive, destination
-collision, or identity change fails closed; the inbox source is not unlinked
-and its wake remains visible. After the exact object is durably present in
-archive, unlinking the source is conditional on the pathname still naming the
-validated inode.
-
-Crash ordering is normative:
-
-1. Persist and fsync the pending state file and its directory.
-2. Write the successor through a no-follow temporary, fsync the file, publish
-   it no-replace at the reserved inbox filename, then fsync the inbox
-   directory.
-3. When superseding, validate and archive the exact predecessor object, fsync
-   the archive directory, conditionally unlink the validated inbox pathname,
-   then fsync the inbox directory.
-4. Only afterward persist the final receipt ring, fsync its state file, rename
-   it into place, and fsync the stream-state directory.
-
-A durable receipt can therefore never precede durable successor bytes. A
-crash before step 4 leaves pending as recovery authority; recovery repeats the
-same ordered, exact-object protocol idempotently.
-
-Nothing is chained, hashed, or validated O(history), and publication work is
-independent of retained stream history. `K` is 128 pending measurement
-(DQ-S3). An ordinary archive receipt remains authoritative for its known
-filename, but random inbox/archive filenames do not form a reverse index from
-`(stream, event-id)` and are not searched as one.
-
-## Supersession (STREAM-R07)
-
-`--supersede` collapses the stream to its latest unread event per `key`
-(absent `key`: per stream) — log-compaction semantics — in wakeup-safe order:
-the successor is published first, then the newest matching receipt among the
-retained `K` whose filename is a no-follow regular inbox file and has no
-same-name archive receipt is archived. The lookup examines at most `K` receipt
-candidates and performs no unread-backlog scan; an older predecessor outside
-the horizon is not compacted. The chosen predecessor filename is persisted in
-the successor's reservation before publication. Immediately before the move,
-both initial publication and recovery validate the predecessor's parsed
-identity, key, and full digest against that retained receipt. A crash between
-the two steps leaves both events unread — the failure bias is a duplicate
-wake, never a lost one — and the next emit validates the successor and
-completes that stored compaction idempotently.
-This is the ordering the differentiation experiment
-proved (steps 3–4 materialize the successor before touching the predecessor).
-The archive move uses the ordinary archive path, so a DING-staged predecessor
-resolves through the existing archive-receipt rule: pasted at most once ever,
-never re-pasted, successor delivers next. Proven: 24 supersedes in 146 ms
-produced one fresh poke, zero staged retries, one unread head
-(`.experiments/2026-08-20-pipes-event-model-differentiation.md`).
-
-## Waits are standing feeds (doctrine, STREAM-R01 + STREAM-R07)
-
-"Wake me when X finishes" — a build in a pty, CI on a PR, a human decision —
-is modeled as a standing stream with the individual wait as `key`, never as a
-per-wait subscription:
-
-```kdl
-agent "demo" {
-  stream "pty" { command "pty-lifecycle-watch" }
-}
-```
-
-One supervised adapter watches all of the agent's pty sessions and emits
-`--key <session>` events on phase changes (superseding) plus a terminal
-exit event. Starting a new build requires no declaration change and leaves
-nothing to clean up; the same shape serves CI (`gh-ci-watch` discovers the
-agent's PRs itself, `key` per PR) and approval watching. This is deliberate:
-the task model has no run-to-completion lifecycle (`TaskLifecycle` is
-`Service | AdoptOnly`), so an adapter that exits on success would relaunch
-into a flap and park. A rare genuinely one-off custom wait uses
-`st2 stream add`/`rm` and an adapter that keeps its process alive; first-class
-completion semantics are deferred to DQ-S8 and, if ever needed, belong in the
-task model rather than a stream-level flag.
-
-## Authoring (STREAM-R02)
-
-```text
-st2 stream add <name> [--command <shell> | -- <program> [<arg>...]]
-st2 stream rm <name>
-```
-
-The launch forms are mutually exclusive. Arguments after `--` are the direct
-non-empty argv form: element zero is the program, hyphen-leading values are
-data, and argument order and bytes are preserved. Omitting both forms creates
-external ingress. Add/rm edit exactly one declaration through the persistent
-catalog-authoring lock with the same source-preserving, fail-closed contract as
-`st2 rename`: unrelated comments, whitespace, ordering, and node bytes remain
-unchanged, while authored `command` or `argv` string values round-trip exactly
-(R25 authority: self or declared descendant; Nix-owned declarations refuse).
-
-`stream rm` is a lifecycle transaction, not merely a source edit. While
-holding the catalog-authoring lock, it strictly resolves the declaration and
-its launch form. An external-ingress stream has no derived runtime and may
-proceed directly to the source transaction. For `command` or `argv`, removal:
-
-1. Derives the one expected runtime identity from the canonical owner and
-   stream name, then verifies its generated-companion ownership marker. An
-   ambiguous, foreign, or unprovable runtime fails closed.
-2. Acquires that exact runtime's lifecycle serialization after the catalog
-   lock. Reconcile/launch paths must acquire the same runtime serialization and
-   therefore cannot relaunch it during removal.
-3. Requests stop/retirement through the ordinary task backend and waits for a
-   durable runtime receipt/state proving both the managed task and its process
-   are absent. Timeout, backend error, or surviving process aborts removal.
-4. Only after confirmed absence publishes the source-preserving declaration
-   removal, fsyncs the source transaction, and releases the locks.
-
-The lock order is catalog-authoring then exact-runtime lifecycle (and any task
-backend locks beneath it). Failure anywhere before step 4 leaves the stream
-declaration byte-identical. If the adapter was already stopped, releasing the
-locks lets ordinary reconcile observe that intact declaration and relaunch it,
-so stop-before-source-publish is recoverable. After step 4, reconcile cannot
-derive the companion and the confirmed-dead process cannot be orphaned.
-Removing an already absent declaration remains idempotent only when strict
-discovery also proves there is no owned derived runtime to retire.
-
-These guarantees apply to the public serialized `st2 stream rm` operation.
-Direct manual edits of `agent.kdl` are outside STREAM-R02 and do not acquire the
-lifecycle transaction; operators must not infer orphan-free teardown from an
-unserialized file edit.
-
-## Verification plan
-
-The invariant rows this subsystem must add or keep green when implementation
-lands: idempotent event ingress (replacing the request-transport row when the
-absorption completes), bounded stream state, supersession-vs-DING safety, and
-the derived-companion row extended to stream tasks. The prototype tests in
-`.experiments/` name the intended proofs; they become `tests/event_e2e.rs`,
-`tests/stream_lifecycle.rs`, and `agent-spec` declaration tests.
-
-## Open design questions
-
-Tracked with context in [open-questions.md](./open-questions.md): DQ-S1
-producer-identity grammar, DQ-S2 state path, DQ-S3 ring bound, DQ-S4 request
-absorption staging, DQ-S5 top-level shared streams, DQ-S6 parked-stream
-owner notification, DQ-S7 event body bounds vs issue #238, DQ-S8 one-shot
-stream completion.

-# Claude batched tool calls under an open permission prompt
-
-## Question
-
-Date: 2026-08-23. Binary: Claude Code 2.1.237 (Fable 5 bundle), Linux, driven under `pty`.
-Purpose: take the capture DQ-H1 (and #268 §C) said was missing — a batch where one call needs
-permission — and settle whether the shipped blocked-exit rule
-(`src/claude_session.rs::observe_hook_event`: clear on next `PreToolUse`/`PostToolUse`/`Stop`)
-false-clears while a prompt is open.
-
-## Method
-
-A scratch project (isolated CWD; hooks are project-scoped) with `.claude/settings.local.json`
-allowlisting `Bash(echo:*)` and registering logging hooks that append every payload as one JSON
-line and always exit 0, for: `PreToolUse`, `PostToolUse`, `PermissionRequest`, `Stop`,
-`SubagentStop` — later runs added `PermissionDenied`, `UserPromptSubmit`, `SessionEnd`.
-
-- Runs 1–2: `claude -p` (non-interactive), 120–180 s timeouts.
-- Runs 3–4: interactive `claude --permission-mode default` in a detached ephemeral `pty` session
-  (`pty run -d -e --id <id> --cwd <proj> --env LOGFILE=… -- claude --permission-mode default`),
-  prompts sent with `pty send --seq … --seq key:return`, screen sampled with `pty peek --plain`,
-  the log dumped **while the prompt was open** and again after answering.
-
-Four short turns total, ≈$0.61.
-
-## Result
-
-**Run 2, `-p`, batch allowlisted-first** (`echo a` + `touch scratch-file.txt`):
-
-```
-PreToolUse  Bash "echo a"                 tool_use_id=toolu_014yt…
-PostToolUse Bash "echo a"                 (before the second call starts)
-PreToolUse  Bash "touch scratch-file.txt" tool_use_id=toolu_01RrZ…
-PreToolUse  Write …                       (fallback attempt, then waits)
-Stop
-```
-
-No `PermissionRequest` fires in `-p` mode; the non-interactive path blocks/denies without one.
-Execution is strictly serial: the first call's `Post` precedes the second call's `Pre`.
-
-**Run 3, interactive, batch permission-first** (`touch scratch2.txt` + allowlisted `echo b`):
-
-```
-481.34  PreToolUse        Bash "touch scratch2.txt"  tool_use_id=toolu_01HK5…  prompt_id=0ea832de…
-481.67  PermissionRequest Bash "touch scratch2.txt"  NO tool_use_id            prompt_id=0ea832de…
-        — prompt open 33 s; log dumped during: NO further event of any kind,
-          although the TUI already rendered the batched `echo b` —
-514.10  PostToolUse       Bash "touch scratch2.txt"  tool_use_id=toolu_01HK5…  (the grant)
-514.30  PreToolUse        Bash "echo b"              tool_use_id=toolu_01NhR…
-514.59  PostToolUse       Bash "echo b"
-516.17  Stop
-519.44  SubagentStop      agent_id="a5c61ec4ef268c3cc" agent_type=""           (phantom, +3.3 s)
-```
-
-**Runs 3b/4, deny path** ("3. No" on the prompt, run 4 with `PermissionDenied` + `SessionEnd`
-registered): after `PreToolUse` + `PermissionRequest`, denial produced **zero further events** —
-no `PostToolUse`, no `Stop`, no `PermissionDenied`. The turn ends silently.
-
-## Conclusion
-
-1. **Execution serializes around an open permission prompt.** In both orderings no hook event
-   fires while a prompt is up — a parallel-batched allowlisted call waits out the grant. The
-   false-clear #268 §C predicted (first call's `Post` clearing `blocked` during the second call's
-   prompt) is unobservable in this build: the next `Pre`/`Post`/`Stop` after `PermissionRequest`
-   is always the blocked call's own resolution. The shipped exit rule is correct, not merely
-   conservative.
-2. **`PermissionRequest` still carries no call identity.** `tool_use_id` is present on
-   `PreToolUse`/`PostToolUse` but absent on `PermissionRequest`; its `prompt_id` is turn-scoped
-   (identical across every event of the turn) and cannot correlate a call.
-3. **Denial is eventless.** Even with `PermissionDenied` registered, "No" ends the turn with no
-   event, so `blockedOn: human` stands until the next `UserPromptSubmit`/`SessionStart`. Half-true
-   semantically (a person's direction is still what the session waits on), but the state axis
-   reads `active` while the model is stopped. Pinned as DQ-H1's residual limit.
-4. **The phantom `SubagentStop` reproduces**: 3.3 s after `Stop`, `agent_id` non-empty,
-   `agent_type` the empty string, no subagent ran — the guard's emergent-property basis holds in
-   this build.
-5. `-p` mode never fires `PermissionRequest`; permission evidence exists only interactively.
-
-## VRS Impact
-
-- DQ-H1 re-resolved: the batched-capture gate is met; the exit rule stands on measured ground and
-  the open question narrows to the eventless deny window.
-- The measured grant sequence is replayed verbatim by
-  `src/claude_session.rs::measured_batched_grant_sequence_holds_blocked_until_the_granted_calls_own_post`.
-- No requirement text changes: OHS-R05's producer rule is confirmed, not amended.

-# OpenCode's server surface, measured for the driver
-
-## Question
-
-2026-08-23, OpenCode 1.18.19 (`/home/example/.nix-profile/bin/opencode`), Linux, isolated
-`XDG_DATA_HOME`/`XDG_CONFIG_HOME`, headless `opencode serve --port 43123 --print-logs`. The free
-anonymous model (`opencode/big-pickle`) answered prompts with no credentials, so every claim below
-is reproducible without an API key.
-
-## Result
-
-**The TUI is a server.** `opencode` (TUI, the default command) starts a server on `--port` /
-`--hostname` exactly like `opencode serve`; `opencode attach <url>` exists for the reverse
-direction. A driver therefore launches the interactive seat with a wrapper-allocated loopback port
-and speaks HTTP to its own child — no screen scraping anywhere in the driver path.
-
-**Observation** rides `GET /event` (SSE). First event is `server.connected`, `server.heartbeat` is
-periodic, and a connect replays ~45 `plugin.added` events — subscribers must tolerate noise and
-duplicates. The API self-describes at `GET /doc` (OpenAPI 3.1, 94 event schemas). Measured and
-schema-verified signals, as projected by the driver:
-
-- `session.status` with a three-arm status union `busy | idle | retry` (measured firing at turn
-  start and end; `retry` carries `attempt`/`next`/`message`);
-- `session.idle` fires beside the idle status (measured);
-- `permission.asked` / `permission.replied` and `question.asked` / `question.replied|rejected`
-  carry stable `^per` / `^que` ids — the blocked-on-human exit edge is id-matched, with none of the
-  Claude batching ambiguity (schema-verified; a live `permission.asked` capture is still owed —
-  with `{"permission":{"bash":"ask"}}` PATCHed into config, the free model's bash ran without
-  asking in one run and emitted no tool part in another);
-- `session.error` is an eight-arm union; `ProviderAuthError` is terminal for the seat, the others
-  leave the session promptable;
-- `GET /session/status` returns `{sessionID: status}` and **omits idle sessions** — measured `{}`
-  when idle, so absence-of-key is the idle proof only over a proven-live server.
-
-**Delivery** is `POST /session/{id}/prompt_async` (measured: returns 200 immediately, empty body),
-which accepts a caller-supplied `messageID` (`^msg`) — idempotent and receipt-correlatable. The
-receipt is the message read back (`GET /session/{id}/message/{messageID}` / the `message.updated`
-event). Prompts sent mid-turn queue natively. **`/tui/append-prompt` and `/tui/submit-prompt`
-returned `true` on a headless server with no TUI attached** — they are broadcast, not receipt, and
-must never count as delivery. Auth is `OPENCODE_SERVER_PASSWORD` + basic auth (user `opencode`),
-unsecured by default on loopback.
-
-**Sessions** are `ses_*`; storage moved to sqlite (`$XDG_DATA_HOME/opencode/opencode.db`,
-`opencode db` exists) — the API is the only sane read path. Exact resume is `--session <id>` /
-`--continue`, forking is `--fork`. No native incarnation concept: st2's runtime generation, the
-pinned port, and the wrapper pid supply fencing.
-
-**Pinning**: `opencode --version` prints the bare version; `Session.version` also rides the wire.
-Because the server serves its own OpenAPI document, a live `/doc` subset check at wrapper start
-covers the shape while a version list covers the semantics — the hybrid of the Codex
-`SUPPORTED_CODEX_CLI_VERSIONS` pattern and the pi type-check pattern.

-
-**Two corrections to the schema-derived design, both shipped:**
-
-1. **Exit events spell the id `requestID`.** Entry events carry `properties.id`; `permission.replied`
-   and `question.replied|rejected` carry `properties.requestID`. The extraction that only knew `/id`
-   would have held `blockedOn: human` forever after a real grant.
-2. **`GET /event` over HTTP/1.1 is `Transfer-Encoding: chunked`** — chunk-size lines interleave into
-   the line-oriented SSE read and a `data:` line can split across chunks (silent event loss). The
-   same server streams raw SSE over an HTTP/1.0 request, so the producer requests HTTP/1.0.
-   JSON endpoints (`/config`, and `/doc` at 478 KB) responded `Content-Length` in every probe, so
-   the one-shot request path is unaffected.
-
-Also measured while live: `prompt_async` with a repeated caller `messageID` yields **one** user
-message (read-back receipt correlation holds; no duplicate delivery), but the second POST appends
-its `parts` again into that message — a resend after a *transiently failed* read-back duplicates
-text inside the message, not the message. The pump's read-back-before-resend rule is therefore
-load-bearing, not just polite.
-
-## Conclusion
-
-The measured server, SSE, receipt, and version-gate surfaces support an
-evented OpenCode driver; the remaining constraints are:
-
-### Limits
-
-- A v2 surface (`/api/event`, `/api/session/{id}/wait`, `permission.v2.*`) coexists with the
-  legacy one probed here; the driver pins the legacy arms via the `/doc` check.
-- Docs move fast (the site showed "Last updated Aug 23, 2026"); the `/doc` gate is the defense.
-- The chunked/1.0 behavior and the `requestID` spelling are measured on 1.18.19 only; both sit
-  behind `SUPPORTED_OPENCODE_VERSIONS` and the `/doc` subset gate.
-
-## VRS Impact
-
-Resolves `DQ-H6` in full: the OpenCode producer is evented (server SSE), uniquely offers an
-id-matched blocked-on-human exit edge, and both blocked pairs are now captured live with the two
-wire corrections above landed as code plus verbatim fixture tests. Feeds the OpenCode producer
-section of `spec.md` (mapping table, aggregate-session rule, receipt semantics, the two-gate
-fail-closed rule) and requirement `OHS-R08`.

-# Observed harness state open questions
-
-Each entry links a spec `DQ-H*`. Questions leave this file when resolved —
-into [spec.md](./spec.md) as decisions or `.experiments/` as tested
-hypotheses.
-
-- **DQ-H1 Claude blocked-exit edge.** The batched capture #268 §C asked for
-  was taken on 2026-08-23 against Claude Code 2.1.237
-  (`.experiments/2026-08-23-claude-batched-permission.md`), and it resolves
-  the predicted false-clear in the rule's favor: **tool execution is
-  serialized around an open permission prompt.** In both batch orderings
-  (allowlisted-first and permission-first), no hook event of any kind fires
-  while the prompt is open — a parallel-batched allowlisted call renders on
-  screen but its `PreToolUse` waits 33 s for the grant — so the next
-  `PreToolUse`/`PostToolUse`/`Stop` after `PermissionRequest` is precisely the
-  blocked call's own resolution, and the shipped rule
-  (`src/claude_session.rs::observe_hook_event`) is correct, not merely
-  conservative. `PermissionRequest` still carries no `tool_use_id` (its
-  `prompt_id` is turn-scoped, shared by every event in the turn — not a call
-  correlator). The residual limit is the **deny path**: selecting "No" ends
-  the turn with *zero* further events — no `PostToolUse`, no `Stop`, and no
-  `PermissionDenied` even when that hook is registered — so `blockedOn: human`
-  stands until the next `UserPromptSubmit` or `SessionStart`. That reading is
-  semantically half-true (a human's direction is still what the session
-  waits on) and it under-reports nothing, but the state axis says `active`
-  while the model is not running. Resolves by: a Claude build whose denial
-  emits any hook event; until then the deny window is the pinned limit.
-- **DQ-H2 Transport cost of per-transition writes — measured 2026-08-23,
-  resolved by the restatement guard.** The live smoke run caught the failure
-  mode: the OpenCode producer restated its state per SSE frame and the
-  envelope re-stamped every restatement — 679 byte-distinct writes in 221 s
-  (~2.7/s while idle). The envelope now makes an unchanged observation a
-  no-op until the refresh cadence is due, so a seat writes on transitions
-  plus at most one re-stamp per five minutes (a Claude turn measured 3
-  writes; a pi turn 2–3). What remains open is only the fleet-scale sync
-  question: nothing yet measures what transition-rate writes cost a
-  600-seat catalog's transport over a day. Resolves by: that measurement on
-  a live catalog.
-- **DQ-H3 `child` has no producer.** The word is reserved because the tuple's
-  reasoning needs it (a long-running foreground command is neither the model
-  working nor idle), but the producer that would have supplied it — the PTY
-  screen observer — is cut: its idle proof was Codex-specific and its Claude
-  arm collided with the empty-composer sentinel (#268 Limits). Resolves by: a
-  harness exposing a positive child-process signal (Claude `PreToolUse`/
-  `PostToolUse` pairs are the candidate), proven against batching.
-- **DQ-H4 Ungraceful-death coverage.** The wrapper's terminal write covers
-  child-reap and SIGTERM; nothing in-process covers SIGKILL escalation into
-  the wrapper's own group or an external forced kill (invariant row 11's
-  case). Same-host readers NARROW the window via the liveness cross-check —
-  only for provably dead sessions; `pty kill` removes the pidfile and leaves
-  the probe indeterminate, so a same-host reader then shares the
-  fifteen-minute horizon (or waits for the next relaunch claim) exactly like
-  a cross-host one. Resolves by: either
-  accepting the horizon (documenting it as the cross-host bound) or a
-  supervisor-side terminal write derived from reconcile's session state —
-  which would need its own fencing rules to avoid a supervisor overwriting a
-  live wrapper's record.
-- **DQ-H5 Supervisor-following behavior.** Root `DQ3` sets two gates for
-  catalog agent state: stale-state behavior (addressed throughout this
-  subsystem) and supervisor-following behavior — what a *remote* supervisor
-  may conclude and do from this record. The second gate is unmet, which is a
-  reason decision 0006's spec ships Draft. #107 already bounds it: a remote
-  `unknown` is no fresh observation, never proof of ill health, and never
-  gates local work. Resolves by: specifying remote-reader semantics with a
-  proof, or explicitly scoping the record same-host advisory.
-- **DQ-H6 OpenCode blocked-entry capture — resolved 2026-08-23.** Both pairs
-  were captured live on a headless 1.18.19 server (the earlier failure to get
-  a prompt came from setting permissions via `PATCH /config`; the same
-  `{"permission":{"bash":"ask"}}` in the *config file* asks reliably, no TUI
-  needed). The capture corrected the producer twice: the entry events carry
-  `properties.id` but the exit events spell it `properties.requestID`
-  (`permission.replied`, `question.replied|rejected`) — the schema-derived
-  extraction would have held `blockedOn: human` forever after a real grant —
-  and `GET /event` over HTTP/1.1 is chunk-encoded, which the line-oriented
-  SSE reader cannot parse safely, so the producer requests it over HTTP/1.0,
-  which the server streams raw. Verbatim captured pairs are fixture tests
-  (`src/opencode_session.rs::captured_permission_grant_pair_enters_and_exits_blocked`,
-  `::captured_question_reply_pair_enters_and_exits_blocked`); the raw frames
-  and commands are in `.experiments/2026-08-23-opencode-surface.md`.

-# Observed harness state requirements
-
-## Context
-
-This subsystem defines observed harness state: the driver-written record of
-what a harness is seen doing, published into the catalog beside the agent's
-declared presence. It refines the slot root [`R08`](../requirements.md) leaves
-undefined — R08 ratifies *declared* activity status and root spec `DQ3` marks
-activity, plan, and plan step "remain undefined" — by specifying the
-*observed* axis only. Declared activity status, current plan, and current plan
-step stay unspecified and are not claimed here. Where this file and the root
-disagree, the root wins and this file is wrong.
-
-Provider-specific idle/active/child/unknown classification belongs to harness
-drivers per [#162](https://github.com/compoundingtech/st2/issues/162); st2
-core owns only the generic envelope, its fencing, freshness, and exposure.
-The record-shape and coverage decisions are recorded in
-[`.decisions/0006`](../.decisions/0006-observed-harness-state-is-a-driver-written-catalog-record.md).
-Delivery gating is explicitly not this subsystem's concern: DING and the
-native transports keep their own evidence
-([`01-ding/requirements.md`](../01-ding/requirements.md)), and no delivery
-path reads the observed-state record. The adjacent native-driver diagnostic
-snapshot reports where that independent evidence path failed; it never
-authorizes or changes delivery.
-
-## Assumptions
-
-- **OHS-A01 Drivers can observe their harness:** Every maintained harness
-  offers a positive observation source — the Codex app-server control stream,
-  Claude lifecycle hooks plus the wrapper's child poll, pi's injected
-  extension, and — conditionally, until `DQ-H6`'s capture confirms its event
-  semantics — OpenCode's server surface, which at this layer is the candidate
-  an experiment must validate before the producer trusts it. Where a source
-  exists the driver
-  projects it; where none exists the driver writes nothing, and the absence of
-  a record is itself honest ("never observed"), never a fabricated state.
-- **OHS-A02 Advisory surface:** Consumers are humans, supervisors, Doctor, and
-  a roster/TUI. The record authorizes nothing: no delivery, no lifecycle
-  action, no reconciliation. A wrong-but-fresh record can mislead an operator;
-  it cannot misdeliver a message.
-- **OHS-A03 Trusted writers:** The record is unauthenticated catalog state
-  under the trusted-fleet model (root `A02`). The writers are the owning
-  session's driver processes — the wrapper that owns the presence lease, and
-  the channel or hook subprocesses it shares its incarnation token with;
-  nothing verifies that claim.
-
-## Acceptable Tradeoffs
-
-- **OHS-T01 Unmeasured transport cost:** Turn boundaries are far more frequent
-  than the five-minute presence refresh, and no measurement establishes what a
-  per-transition replicated write costs on a real catalog under a real
-  transport (`DQ-H2`). v1 accepts this, bounded by writes only on transition
-  plus the slow heartbeat.
-- **OHS-T02 Blocked is vacuous under bypass:** `blockedOn: human` can only be
-  produced where a harness asks a human anything. Under Claude
-  `bypassPermissions` — what `examples/native/agent-claude.kdl` ships — the
-  axis never fires. The field is still v1: a later-added axis decodes as
-  `unknown` in every pinned reader, the opposite of a conservative default.
-- **OHS-T03 No history:** v1 records only the current state. Measured burst
-  coalescing (4 transitions per turn, 0.1–0.4 ms apart, #268) would erase any
-  state shorter than the coalescing window, so a v1 history could not be
-  truthful about dwell time. `transitions` and `sinceMs` keep a later history
-  additive.
-- **OHS-T04 Ungraceful-death windows:** SIGKILL cannot be caught, so an
-  external forced kill can leave a live-state record whose writer is gone.
-  Same-host readers narrow that window with the liveness cross-check
-  (OHS-R07) where the session is PROVABLY dead — pidfile present, process
-  gone — while `pty kill` removes the pidfile and leaves the probe
-  indeterminate for the rest of the window; the next session's written
-  ownership claim supersedes the orphan at relaunch, and cross-host readers
-  wait out the staleness horizon.
-
-## Requirements
-
-### Must publish one observed envelope
-
-- **OHS-R01 Observed envelope:** Each agent has at most one observed-state
-  record, `<agent-dir>/harness-state`, schema `st2.harness-state.v1`, written
-  only by the owning session's driver processes — the wrapper, its channel,
-  or its hooks; one logical owner per record, sharing one incarnation token,
-  and nothing outside the driver writes it. It carries the full v1
-  tuple: `state ∈ idle | active | child | ended`, `blockedOn ∈ human | none`
-  (with `ask ∈ none | permission | question | review` naming the kind of
-  human ask machine-readably, so no consumer branches on `reason`; `review`
-  is reserved — no maintained producer emits it),
-  `inputBuffer ∈ empty | nonempty | unknown`, plus the observing harness, a
-  diagnostic `reason` no consumer branches on, and fencing/freshness fields.
-  `child` is reserved: part of the contract, decoded by v1 readers, no
-  producer yet (`DQ-H3`). The record is additive-tolerant on read; unknown
-  future enum words decode as indeterminate, never as any definite value.
-- **OHS-R02 Derived-only unknown:** `unknown` is mandatory in the read
-  vocabulary, derived, and never written. One constructor produces every
-  indeterminate observation, each absence carries a distinct reason
-  (malformed, stale, future-skew, session-dead), and no path derives `idle` —
-  or anything else — from missing evidence. A missing record reads as "never
-  observed", which is distinct from `unknown`.
-- **OHS-R03 Transport-safe freshness:** Freshness lives in the record bytes:
-  an embedded origin timestamp with its own staleness and future-skew
-  constants, deliberately not aliases of the presence constants. No read path
-  consults file mtime. Every write is byte-distinct, so a transport that
-  carries content but not metadata always carries a refresh.
-
-### Must never wake what it informs
-
-- **OHS-R04 Scoped delivery-input watching:** A write to the observed-state
-  record wakes no delivery pump, no reconciliation pass, and no watcher owned
-  by its own writer. Delivery pumps watch their inbox and the presence record,
-  not the agent directory wholesale. This is a prerequisite: the record sits
-  in a tree the Codex pump watches unfiltered today.
-
-### Must be produced by drivers under the evidence rule
-
-- **OHS-R05 Driver-owned projection:** Classification is driver work. The
-  Codex producer projects the existing control state with the corrected rows:
-  `ActiveWithoutTurn`, `ConflictingTurn`, and `Review` report `active` —
-  review's enter and exit are model-emitted items inside a running turn, so
-  nothing there awaits a human (matching the projection's
-  `Held { Review }` → `active` / `blockedOn: none` row) — while
-  `WaitingOnApproval` and `WaitingOnUserInput` report `active` with
-  `blockedOn: human`. `Compaction` and `UnknownProtocol` report `active`, and
-  `NotLoaded`/`SystemError`/`AwaitingStatus` withhold rather than write.
-  `Held` — a delivery predicate — never appears in the published vocabulary.
-- **OHS-R06 Heartbeat only on evidence:** A writer re-stamps the record on the
-  presence cadence only while it still observes its harness, and stops on
-  evidence loss so the record ages to `unknown` instead of staying confidently
-  wrong. On teardown the wrapper writes its terminal record — carrying the
-  exit outcome — *before* any escalation that could take the wrapper itself,
-  and a terminal record is never re-stamped.
-- **OHS-R07 Liveness cross-check:** The record names the pty session whose
-  liveness vouches for its live states. A same-host reader that positively
-  proves that session dead — its pidfile present, its process gone — reads
-  the record as `unknown` even while fresh; an indeterminate probe (an
-  unreadable registry, or a pidfile `pty kill` already removed) downgrades
-  nothing — unprovable evidence is never reported as death. The check is a
-  narrowing, not a closure: what it cannot prove, the relaunch-time written
-  claim supersedes and the staleness horizon bounds. A fresh `ended`
-  survives the check: a terminal record is supposed to outlive its writer.
-- **OHS-R08 All-harness coverage:** Codex, Claude, pi, and OpenCode each ship
-  a producer. pi's is evented through the injected extension (the positive
-  idle signal root `DQ2` asks for). OpenCode reaches driver parity first —
-  typed driver, session wrapper owning the presence lease, then its producer
-  and native delivery transport.
-
-### Must be readable beside declared presence
-
-- **OHS-R09 Roster join:** `st2 agents --json` carries `observedState` beside
-  declared `status` in one payload — the wedged-agent comparison (declared
-  `busy`, observed `idle`) must not require joining two commands. Observed
-  state is a third independent axis: it never rewrites presence, desired
-  lifecycle, or `lastActivity`, and the pinned roster wire assertions change
-  deliberately, in the same change, with the new proof named.
-- **OHS-R10 Doctor exposure:** Doctor surfaces observed state for agents it
-  owns as advisory output — a stale or session-dead record beside a `running`
-  desired state is worth a warning, never an exit-code failure in v1.
-
-### Must make native-driver degradation structured and recoverable
-
-- **OHS-R11 Closed driver diagnostic:** Each agent has at most one current
-  `<agent-dir>/driver-diagnostic` record, schema
-  `st2.driver-diagnostic.v1`, owned by native driver core. The tagged,
-  additive-tolerant snapshot carries a closed stage, reason, source, producer
-  version/support classification, origin timestamp, and clearing contract.
-  Readers derive evidence age. Generic roster and Doctor consumers branch on
-  these typed fields, never provider error prose.
-- **OHS-R12 Fail-visible reading:** An absent record is explicitly `absent`;
-  malformed bytes, an unsupported schema, unknown vocabulary, future clock
-  skew, or a known reason paired with the wrong stage/source are
-  `indeterminate`. None reads
-  as healthy. A valid record is `failure`; success is represented only by
-  stage recovery clearing that stage, with the record removed after the last
-  outstanding stage recovers.
-- **OHS-R13 Exact OpenCode boundaries:** The OpenCode driver publishes or
-  clears diagnostics at `versionGate`, `apiGate`, `sse`, `seed`, `delivery`,
-  and `readBack`. The in-process publisher retains at most one failure per
-  stage and persists the earliest failing boundary, so a downstream transport
-  symptom cannot hide an admission failure. Publishing is advisory and must
-  not change prompt submission, retry, durable read-back, or archive
-  semantics.
-- **OHS-R14 Shared exposure and repair:** `st2 agents --json` carries the
-  complete `driverDiagnostic` projection for every row, including explicit
-  absent and indeterminate states. For a declaration whose native driver
-  publishes the record (OpenCode, Claude, Codex, omp in this version), Doctor
-  reads the same core projection and emits advisory-only stable repair text for
-  every state; the two surfaces cannot independently interpret provider strings.
-  Absence is advised only for a driver that publishes a boundary result on
-  every launch: Claude and omp publish only on a credential rejection, and
-  Codex publishes only on a credential rejection or degraded safe-fallback
-  boot. On an automatic Codex remote resume, the driver removes CLI permission
-  flags that the resume subcommand rejects and reapplies their declared policy
-  through typed `thread/resume`. A rejected projection is retried exactly once
-  without overrides so the conversation still boots, and remains visibly
-  degraded. Absence is otherwise their healthy steady state and earns no
-  advisory.
-- **OHS-R15 Bounded telemetry:** Each failure/recovery transition emits a
-  driver-diagnostic span/event and counter. Metric labels and `span.label`
-  are limited to closed `driver`, `stage`, `reason`, `source`, `support`, and
-  `outcome` vocabularies. Raw versions and any agent/runtime/session/message
-  identity are forbidden from metric labels and `span.label`; raw prompt,
-  message body, and path data are forbidden from the durable record and all
-  labels.
-- **OHS-R16 Provider credential boundary:** A `providerAuth` stage carries the
-  single reason `providerAuthRejected` from the single source `turnResult`, and
-  is published by the Claude, Codex, and omp drivers from their own typed
-  turn-failure signal — never from provider prose and never from credential
-  knowledge, which st2 does not hold. It projects between `seed` and
-  `delivery`: the four gates that prove st2 can read the producer at all
-  outrank it, and the delivery and read-back symptoms it causes do not. The
-  same rejection sets `observedState.reason` to `providerAuth`, the word the
-  OpenCode producer already publishes. Only positive evidence — a turn that
-  reached its ordinary end — clears it; an unclassified failure leaves a
-  standing rejection standing. Delivery semantics are unchanged.
-
-## Evidence
-
-The measurements are #268's, taken 2026-08-16/17 on one host and carried with
-their original caveats: 1298 presence files all legacy one-line records, 4
-transitions per turn 0.1–0.4 ms apart, Claude hook timelines (blocked entry in
-2 of 9 captures, exit in 1), silent Claude death under SIGTERM/SIGKILL, and
-the Codex `activeFlags` schema present in the measured codex-cli versions
-(#268's first comment). The startup gate now checks that generated schema
-directly. The shipped code evidence is in-repo: the Codex state
-machine and its hold reasons, the unfiltered agent-dir watch beside the
-presence refresh that writes into it, and `src/harness_state.rs`, which
-implements the envelope this file ratifies.

-# Observed harness state specification
-
-This document specifies the observed-harness-state record. It builds on
-[requirements.md](./requirements.md). Declared presence remains in the root
-spec's R08 section; terminal delivery remains in
-[`01-ding/spec.md`](../01-ding/spec.md) and reads none of this.
-
-## Status
-
-Draft. The envelope (`src/harness_state.rs`), all four producers, the scoped
-delivery-input watcher, the native-driver diagnostic snapshot, and the
-roster/Doctor exposure are implemented; the former DELTA-005 fence is
-resolved and deleted, and the DQ-H1 and DQ-H6
-captures are taken and folded in. Draft status remains for the genuinely
-unmet residuals: root `DQ3`'s supervisor-following gate (`DQ-H5`) and
-Claude's eventless deny path (the remaining `DQ-H1` window). Open questions
-are tracked in [open-questions.md](./open-questions.md).
-
-The `agent` field's immutable-ID meaning is the accepted target, and it ships
-as a new record version, `st2.harness-state.v2`: this record's version suffix
-is its read contract, so changing an existing field's meaning reserves the next
-version rather than reusing `v1`. Records and producers stay on
-`st2.harness-state.v1`, whose `agent` remains a bus identity, until
-[DELTA-003](../.delta/DELTA-003-agent-address-not-implemented.md) closes.
-Version 2 is otherwise identical to the shape below. The reader-first rollout
-accepts both versions — narrowing the `unsupported-schema` rule below to
-versions outside that pair — before any version-2 writer activates.
-
-## Scope
-
-This specification defines the observed-state record, its freshness and
-derivation rules, the per-harness producers, the adjacent native-driver
-diagnostic record, and their roster/Doctor exposure. It does not define:
-transition history or a `--watch` surface (deferred, OHS-T03); idle thresholds,
-escalation, or notification policy (#173's, per root `R20`); the withdrawn
-host-local hot tier; the cut PTY screen observer; or any `AGENT-SPEC.md`
-change (separate authority, root `DQ3`).

-Field rules, matching `src/harness_state.rs`:
-
-- `state` on disk is never `unknown` (OHS-R02) and never `child` today
-  (`DQ-H3`). Readers decode both, plus unrecognized future words as `unknown`.
-- `blockedOn` unrecognized words decode indeterminate, never `none` — a v2
-  axis value must not read as "not blocked".
-- `ask` names what kind of human ask holds the harness, machine-readably —
-  the axis consumers filter on (`reason` stays diagnostic). Meaningful only
-  while `blockedOn` is `human`; writers emit `none` otherwise, records from
-  writers predating the axis default to `none`, and unrecognized future words
-  decode indeterminate.
-- `incarnation` is the writing session's token and `seq` its monotonic
-  ownership sequence. A claim is a WRITTEN act under the record lock: the
-  session starting up writes an exitless `ended (superseded)` takeover
-  record carrying its token and a sequence one above the highest this seat
-  has seen — the maximum of the on-disk record's sequence and the
-  `.harness-state.seq` floor sidecar, a sibling file (written
-  stage-and-rename under the same lock on every claim) that keeps claims
-  monotonic even when the record itself is unreadable. Racing
-  claimers therefore mint distinct sequences, and a predecessor's
-  still-fresh live record is superseded at relaunch, where the
-  pty-name-based probe cannot tell sessions apart; readers derive
-  indeterminate (`claimed`) from the fresh placeholder — a fence is not an
-  observation — until the session's first real observation. Ownership
-  — coalescing, heartbeat eligibility, terminal suppression (which applies
-  only to exit-bearing terminal records, never the claim placeholder) — is
-  token equality with the claim's direction: a straggler whose claim is
-  below the on-disk sequence is refused in live and terminal paths alike,
-  and a token-only writer never claims — it adopts its own session's
-  records, starts virgin ones, and is refused against foreign tokens.
-  Sibling writer processes of one session share the claimer's exported
-  token and sequence; records predating either field decode with an empty
-  token and sequence zero, which no session owns and any claim supersedes.
-  The residual: with the record unreadable AND the floor sidecar missing or
-  damaged, a claim restarts at sequence one and a lingering predecessor
-  holding a higher sequence could fence it — accepted, because it takes
-  both files independently damaged, and refusing the claim instead would
-  wedge the seat permanently.
-  Every landed write carries a strictly monotonic per-record stamp (never
-  inherited from beyond the future-skew trust bound) so it stays
-  byte-distinct even against a same-millisecond predecessor.
-- `reason` is diagnostic only; no consumer branches on it.
-- `ptySession` fences every live state: a writer refuses a live observation
-  that names no session (only `ended` may omit it), because a live record the
-  probe cannot check would stay definite straight through an external SIGKILL.
-- `sinceMs` is when the current state was entered and survives heartbeat
-  re-stamps; `writtenAtMs` is the heartbeat. `transitions` is a monotonic
-  counter continued across writer restarts; with `writtenAtMs` it keeps every
-  write byte-distinct.
-- Writes are session-owned by incarnation token, and ownership has a
-  DIRECTION through `seq`. A claim is a WRITTEN act under the record lock —
-  an exitless `ended (superseded)` takeover record carrying the new token
-  and a sequence one above the highest the seat has seen (the on-disk
-  record's or the `.harness-state.seq` floor sidecar's, whichever is
-  higher, so an unreadable record does not restart the sequence) — so
-  racing claimers serialize and mint
-  DISTINCT sequences (no tie exists), and a predecessor's still-fresh live
-  record is superseded at relaunch; readers derive indeterminate (`claimed`)
-  from the fresh placeholder until the session's first real observation. A
-  straggler from a superseded session (its claim below the on-disk sequence)
-  is refused in live and terminal paths alike, a token-only writer never
-  claims (it adopts its own session's records, starts virgin ones, and is
-  refused against foreign tokens), and terminal suppression applies only to
-  exit-bearing records — never the claim placeholder. `sinceMs` never spans
-  a restart; a lingering predecessor can neither heartbeat nor overwrite its
-  successor's record.
-  Heartbeats and coalescing never touch a record whose schema or token the
-  writer does not own; a foreign record is left byte-identical by heartbeats
-  and replaced only by a claiming observation. One residual, stated:
-  Claude's exported ownership pair is visible to its tool children like
-  every other hook-environment value (`ST_AGENT` included) — pi stashes and
-  unexports instead because pi fronts its own environment onto every bash
-  child, an architectural difference, not an oversight.
-- Deserialization is additive-tolerant (no `deny_unknown_fields`): a reader
-  may be older than its writer.

-## Derivation (OHS-R02, OHS-R07)
-
-What a reader reports, in evaluation order:
-
-| Evidence | Reads as | Reason |
-| --- | --- | --- |
-| No record file | no observation (`null`) | never observed ≠ `unknown` |
-| File exists but cannot be read | `unknown` | `unreadable-record`; an IO error is indeterminate, never absence |
-| Unparseable bytes, or bytes not shaped like an accepted version | `unknown` | `malformed-record`; never falls back to mtime |
-| `schema` is neither `st2.harness-state.v1` nor, once tolerant readers ship, `st2.harness-state.v2` | `unknown` | `unsupported-schema`; a future schema's words may be spelled like this version's while meaning something else |
-| `writtenAtMs` > now + 60 s | `unknown` | `future-skew` |
-| `writtenAtMs` ≤ now − 15 min | `unknown` | `stale` |
-| Literal `unknown` state (never written by this crate) | `unknown` | `literal-unknown` |
-| Live state, same-host probe proves `ptySession` dead | `unknown` | `session-dead` |
-| Live state, probe available, record names no `ptySession` | `unknown` | `unfenced-record`; nothing to check is not the same as checked |
-| Live state, probe indeterminate | the recorded state | unprovable evidence downgrades nothing |
-| Fresh claim placeholder (`ended`, exitless, reason `superseded`) | `unknown` | `claimed`; a fence is not an observation |
-| `ended`, any probe result | `ended` | a terminal record outlives its writer |
-| Otherwise | the recorded tuple | — |
-
-Every `unknown` row routes through one constructor and blanks every axis;
-there is no path from any absence to a definite state.
-
-Two reader-side limits, stated before anyone finds them: `pty kill` removes
-the session pidfile, so the liveness probe reads *indeterminate* rather than
-*dead* after it — a seat that was `active` when killed genuinely reads
-`active` (measured), with Doctor silent, until the staleness horizon or the
-next session's written claim supersedes the orphan at relaunch, whichever
-comes first. The cross-check is a narrowing of the ungraceful-death window
-(provably dead sessions: pidfile present, process gone), not its closure —
-OHS-T04/OHS-R07 say exactly this, and no death tombstone is attempted: the
-kill that removes the registry entry leaves nothing behind to prove death
-with, and fabricating evidence is the one thing this design never does.
-
-Each controlled Codex startup generates the installed app-server schema. st2
-checks the required methods, response fields, blocking flags, and data shapes
-that native delivery uses. A compatible patch or minor release starts without
-a source change. A missing required element or a changed critical shape stops
-before the app-server starts. The wrapper sends one idempotent rejection report
-to the agent's declared supervisor. The version string is diagnostic data, not
-an admission proxy.
-
-Additive item kinds and server-request methods do not stop startup. A listed
-element is reviewed and safe to ignore. An unlisted element creates an
-`UnknownProtocol` delivery hold. The next safe thread status releases the hold.
-This fail-closed runtime rule keeps the agent present and prevents a silent
-delivery into a new hold that st2 does not understand.
-
-## Codex producer (OHS-R05)
-
-The projection reads the state the control pump already maintains; it adds no
-observation path. `Held` never enters the published vocabulary — it is the
-complement of steerable, a delivery predicate (decision 0001's boundary).
-
-| `CodexObservedState` | state | blockedOn | ask | reason |
-| --- | --- | --- | --- | --- |
-| `AwaitingStatus` | *withhold* | — | — | no evidence yet; the record ages |
-| `Idle` | `idle` | `none` | `none` | |
-| `Active { turnId }` | `active` | `none` | `none` | |
-| `TerminalError { systemError }` | `ended` | `none` | `none` | `systemError` |
-| `TerminalError { providerAuthRejected }` | `ended` | `none` | `none` | `providerAuth` — a failed turn whose typed error names `unauthorized`; the same word the OpenCode producer publishes |
-| `Held { ActiveWithoutTurn }` | `active` | `none` | `none` | `activeWithoutTurn` — Codex said active; st2 merely cannot name a steerable turn |
-| `Held { ConflictingTurn }` | `active` | `none` | `none` | `conflictingTurn` — two turns believed live is maximally active |
-| `Held { Review }` | `active` | `none` | `none` | `review` — review's enter and exit are model-emitted items inside a running turn; nothing awaits a human |
-| `Held { Compaction }` | `active` | `none` | `none` | `compaction` |
-| `Held { UnknownProtocol }` | `active` | `none` | `none` | `unknownProtocol` — an additive protocol element blocks delivery until a safe thread status arrives |
-| `Held { WaitingOnApproval }` | `active` | `human` | `permission` | `waitingOnApproval` |
-| `Held { WaitingOnUserInput }` | `active` | `human` | `question` | `waitingOnUserInput` |
-| `Held { NotLoaded }` | *withhold* | — | — | thread not loaded proves nothing about work |
-| `Held { SystemError }` | *withhold* | — | — | see #264's catch-all defect |
-| `Held { UnknownStatus }` | *withhold* | — | — | an unrecognized future status is not a terminal `systemError` and cannot authorize delivery |
-
-`inputBuffer` is `unknown` from this producer: the control stream does not see
-the composer. The projection test must be behavioral — a table that would pass
-with every row mapped to `unknown` is not an oracle (#268 §B). The wrapper
-honors st2's stop signal through every startup phase (socket connect,
-initialize, thread binding), not only the bound monitor loop: a stop before
-the TUI exists ends the launch gracefully and leaves no record — nothing was
-observed — while a stop after it exits through the ordinary terminal-write
-path — and the stop handler installs before ANY child is spawned, the
-hook-trust preflight's detached app-server included, with the stop flag
-polled between short socket timeouts through every startup wait (connect,
-the initialize handshake, thread binding, and the preflight's projection
-read), so a stop in that window cannot leak a server around a dead wrapper
-or sit out a 30-second handshake. Observability never kills a
-launch: a claim that cannot be written degrades to a token-only writer with
-a warning, a TUI that fails to spawn writes a real terminal record (ended,
-launch-error) over the claim placeholder, and a projected transition whose
-record write fails does not count as evidence: it is retained as pending and
-retried on EVERY pump pass (only the heartbeat is presence-cadence work), so
-a stale on-disk state is never kept fresh in contradiction of the latest
-observation.
-
-## Claude producer (OHS-R05, OHS-R06)
-
-Two cooperating writers. The hook side classifies turn lifecycle: a submitted
-prompt or tool activity writes `active`; `Stop` writes `idle`; `StopFailure`
-— which Claude fires *instead of* `Stop` when an API error ended the turn —
-also writes `idle`, because the turn is over at the same lifecycle point, with
-reason `providerAuth` for the credential class and `apiError` for every other
-word in that closed vocabulary. It is deliberately not `ended`: the TUI is
-still live, a human can re-login and carry on, and the wrapper owns this seat's
-terminal record (OHS-T04). The event carries a second registered command, the
-pre-existing wedge reporter, so both jobs run on one edge;
-`PermissionRequest` writes `active` + `blockedOn: human` with its ask kind
-classified from the payload's `tool_name` (`AskUserQuestion` → `question`,
-anything else → `permission`) — (its meaning is
-specifically "a human is about to be asked" — it fires only under permission
-modes that ask), classifying its ask kind from the payload's `tool_name`:
-`AskUserQuestion` is a `question`, anything else a `permission`. Events carrying `agent_id` are subagent-nested and never move
-top-level state. The blocked *exit* edge is the next `PreToolUse`,
-`PostToolUse`, or `Stop` — measured-correct, not merely conservative: the
-2026-08-23 batched-permission capture (`DQ-H1`) shows tool execution
-serializes around an open permission prompt, so no event can clear the
-blocked state early. The residual limit is the eventless deny path pinned in
-`DQ-H1`. The wrapper side owns liveness: it re-stamps the heartbeat on its
-existing presence cadence while the child is alive — through a fresh writer
-each time, so it never clobbers a state a hook process wrote in between —
-and writes the terminal record from its `try_wait` reap and its SIGTERM
-path, before any SIGKILL escalation into its own process group, which no
-in-process write survives (OHS-T04). Hook registration has one canonical
-shape (`hooks::claude_settings_registration`): the maintained example
-declaration (`examples/native/agent-claude.kdl`) carries it by hand, and
-`expand_claude` renders the same `.claude/settings.local.json` upsert for
-driver-declared seats, so both surfaces register identical hooks and a test
-fails if they drift. A live seat converges without disruption: render output
-is not part of the launch fingerprint, the merged settings land on the next
-materialization pass, and the hooks take effect at the next session start.
-The registration merges with `arrays="union"`: user-declared hook entries
-survive every materialization, while st2's own prior entries — recognizable
-by the hook root they reference — are superseded on a hook-set upgrade
-rather than accumulated. Hook writes carry the wrapper's exported
-incarnation token, so a hook finishing after the wrapper reaped Claude
-cannot replace the terminal record. Legacy `deliver "mcp"` seats render the same
-canonical registration — they run under claude-session too, and a wrapper
-that claims and ends a record nobody transitions would be worse than no
-record. A hooks-only seat (the maintained hand-authored example launches
-claude directly) gets transitions and blocked-on-you but no heartbeat owner
-and no terminal record: its `SessionStart` performs the written claim so
-session succession works — eligibility and the takeover are ONE act under
-the record lock, so a hooks-only SessionStart racing a wrapper's startup
-cannot steal its sequence, and a wrapper's fresh claim placeholder counts
-as owned (an abandoned one ages into claimability); a wrapperless claimer
-otherwise supersedes only fellow wrapperless tokens, real exit-bearing
-terminal records, and staleness — while a live-but-idle seat still ages to
-`unknown` and an exit leaves its last state to age out — indeterminate,
-never wrong.
-
-## pi producer (OHS-R05, OHS-R08)
-
-The injected extension observes `agent_start`/`agent_settled` — a positive,
-evented, in-process signal; the idle edge is deliberately `agent_settled`,
-because `ctx.isIdle()` is still false through `agent_end` and a queued
-follow-up turn starts exactly at that boundary (measured against the repo's
-own pi captures). Ownership splits by phase rather than living in one
-process: the channel owns the live record and its heartbeat, because it is
-the one process that sees pi's turn events and its stdio EOF bounds its
-evidence, while the wrapper owns only the terminal record — through a terminal-only
-observer that never heartbeats but does write `ended` *before* the stop
-path's SIGKILL escalation of its own group, the one write that makes an
-escalated stop observable at all — because it is the
-one process that sees the provider die — and the channel drops queued live
-frames once a terminal record is on disk, so the wrapper's write is the
-incarnation's last word. This is the first producer that satisfies root
-`DQ2`'s "stronger evented signal" clause for any harness. pi's composer
-offers nothing to scrape, so `inputBuffer` stays `unknown`.
-
-## OpenCode producer (OHS-R08)
-
-OpenCode's interactive TUI is also a server, so the driver needs no screen
-observation at all (measured on 1.18.19 —
-`.experiments/2026-08-23-opencode-surface.md`). The `opencode-session` wrapper
-allocates a loopback port and a per-seat password, launches the TUI bound to
-them, owns the presence lease and the observed-state record, and projects the
-`/event` SSE stream:
-
-| Signal | state | blockedOn | ask | reason |
-|---|---|---|---|---|
-| `session.status {type: busy}` | `active` | `none` | `none` | — |
-| `session.status {type: retry}` | `active` | `none` | `none` | `retry` |
-| `session.status {type: idle}` / `session.idle` | `idle` | `none` | `none` | — |
-| `permission.asked` … `permission.replied` (same ask id; spelled `id` on entry, `requestID` on exit — measured) | `active` | `human` | `permission` | `permission` |
-| `question.asked` … `question.replied\|rejected` (same ask id, same spelling split) | `active` | `human` | `question` | `question` |
-| `session.error {ProviderAuthError}` | `ended` | `none` | `none` | `providerAuth` |
-| `session.error` (other arms) | `idle` | `none` | `none` | `error:<name>` |
-| child exit / stop path | `ended` | `none` | `none` | exit status |
-
-A dedicated seat aggregates across the server's sessions: any busy session is
-activity, any open ask is a human block, and idle requires positive level
-evidence (`/session/status` omits idle sessions, so an empty map over a live
-server is the idle proof, re-read on every SSE (re)connect). Asks open across
-a reconnect are recovered from both pending listings — `GET /permission` and
-`GET /question`, each measured on 1.18.19 — with their ids kept so the
-id-matched exits still release them; the seed builds a fresh projection and
-swaps it in whole only when the status level (which must be the documented
-object shape — null or an array proves nothing), every status word, and both
-listings all read cleanly — a listing entry without a readable id is a
-pending ask the id-matched exit could never release, so it fails the seed
-rather than being skipped. A mid-seed failure leaves nothing half-seeded, a
-successful re-seed clears stale entries whose exits passed during the
-outage, and otherwise evidence stays off and the seed retries. An
-unrecognized `session.status` word on ANY session poisons the projection
-outright — a tracked-busy entry can no longer be trusted to clear, and an
-untracked session in a state this version cannot read makes standing idle
-evidence a fabrication — so non-terminal observations are withheld (a
-sticky terminal still outranks the poison) and evidence drops until a fresh
-seed replaces the picture. An SSE drop marks the observation
-stream interrupted, so the first post-reseed observation opens a fresh
-transition rather than claiming continuity across the outage. The `/doc`
-subset gate names every consumed arm, exit events and pending listings
-included, so a release renaming an exit is refused up front rather than
-holding `blockedOn: human` forever. A dropped stream stops the heartbeat, the
-stream carries a silence horizon of at least twice the measured heartbeat
-cadence so a stalled socket surfaces as a disconnect instead of keeping
-evidence alive forever, and `inputBuffer` stays `unknown` — the `/tui/*`
-surface is write-only.
-
-The native delivery transport mirrors the Codex FIFO discipline: an
-`Attempted` receipt persisted before transport, `POST
-/session/<id>/prompt_async` with a stable caller `messageID` derived from
-(identity, session, filename), and acceptance only when the exact message
-reads back durably from the server. The `/tui/append-prompt` and
-`/tui/submit-prompt` endpoints acknowledge input even with no TUI attached
-(measured) and are therefore never a receipt. Delivery is fail-closed behind
-two gates: a `SUPPORTED_OPENCODE_VERSIONS` pin and a live `/doc` OpenAPI
-subset check naming every arm st2 consumes; observation runs behind the
-`/doc` check alone, since its vocabulary already degrades to indeterminate.
-Deliveries target the most recently observed session; a seat whose TUI has
-not yet created one waits rather than creating sessions itself, and a session
-that settled before the observer connected — invisible to events and to
-`/session/status` alike — is recovered from the session listing when work is
-pending. The status seed trusts exactly the pinned words (`busy`, `retry`,
-`idle`) and fails closed on anything else, and the stop path rewrites its
-pre-signal escalation cover with the exit the grace-window reap actually
-observed.

-
-`producerVersion` is omitted when the version probe cannot produce one.
-`support` is `supported | unsupported | unknown`; an unrecognized future word
-is distinct from the literal supported vocabulary and makes the record
-indeterminate. Unknown additive object fields are ignored. Unknown enum words,
-a foreign schema/recovery contract, an empty driver, or a known reason paired
-with the wrong stage/source are never accepted as failure evidence.
-
-The closed stage/reason/source matrix is:
-
-| Stage | Reasons | Sources |

-A fresh publisher inherits the readable projected failure for the same driver,
-so a later Claude hook process cannot hide an unresolved credential rejection
-with a turn failure. One in-process publisher retains at most one failure per stage and
-persists the earliest stage in the table's execution order. Re-publishing the
-same tuple is a no-op; it does not refresh `observedAt` or increment telemetry.
-A stage success clears only that stage and atomically reveals the next
-outstanding failure. Clearing the final failure removes the record. At a new
-session, a measured stage success may clear a matching persisted failure from
-the predecessor, so recovery never requires an st2 restart beyond the restart
-that was itself needed to cross a static version/API gate.
-
-OpenCode publishes and clears at the actual boundary, not at a catch-all error
-renderer:
-
-1. `opencode --version` resolves version support before launch.
-2. `/doc` reachability and exact subset compatibility resolve the API gate.
-3. `/event` connect/disconnect/silence and unknown event status resolve SSE.
-4. `/session/status`, `/permission`, and `/question` resolve the atomic seed.
-5. `prompt_async` transport reachability/status resolves delivery.
-6. Exact message GET `200`/`404`/indeterminate resolves read-back.
-
-Diagnostic persistence errors log and do not escape into those operations.
-The existing attempted-before-transport receipt, same-message retry,
-indeterminate-read-back no-resend rule, durable acceptance, and archive
-behavior are unchanged.
-
-Claude and Codex publish `providerAuth` and `turn` from their typed failure
-signals. omp publishes `providerAuth`. Codex additionally publishes `launch` /
-`launchConfigurationRejected` / `processExit` when a declared-argument
-rejection forces its one bounded known-safe boot fallback, and clears it on the
-next exact-config boot. The wrapper's owner-only diagnostic names declared
-options but never their free-form values; only the closed approval, reviewer,
-and sandbox vocabulary used to verify a resume projection may appear as a
-value. The typed record exposes degraded mode to
-roster and Doctor. Automatic remote resume never forwards approval, sandbox,
-or hook-trust flags to the resume subcommand. Hook trust is projected during a
-typed preflight; approval and sandbox are projected in the driver's redundant
-typed `thread/resume` request after the TUI has loaded the bound thread. The
-driver verifies the response's effective policy. If the provider rejects that
-request, it retries `thread/resume` exactly once without permission overrides;
-if the response reports a different policy, it accepts the live conversation
-but marks the same known-safe degraded mode. Other earlier boundaries remain fail-closed at admission
-(an incompatible Codex protocol refuses the launch, an unadmitted omp MINOR
-refuses it under OMP-R05, and st2 gates no Claude version at all). Provider-auth
-edges come from the signal that ends a turn, so no driver reads provider prose
-to decide them:
-
-| Driver | Rejection | Recovery | `producerVersion` / `support` |
-| --- | --- | --- | --- |
-| Claude | `StopFailure` hook with `error: authentication_failed` — Claude's own name for every 401/403 provider response, fired *instead of* `Stop` | the next `Stop`, i.e. a turn that reached its ordinary end | omitted / `unknown` — a hook payload names no version and st2 gates none |
-| Codex | `turn/completed` with `turn.status: failed` and `turn.error.codexErrorInfo: unauthorized` | `turn/completed` with `turn.status: completed` | the version the protocol gate admitted / `supported` |
-| omp | a `type: "turn"` channel frame whose error carries omp's own `errorId` classification with `AuthFailed` set and `UsageLimit`, `AccountPolicy`, and `Transient` clear | a `type: "turn"` frame with no error, i.e. an `agent_end` whose last assistant message did not stop on an error | omitted / `unknown` — the wrapper, not the channel, owns the version gate |
-
-Turn causes are advisory evidence from Codex's `error` notification and Claude's
-`StopFailure` hook. They never change delivery eligibility or invent a human
-blocker. Repeated identical failures preserve the original evidence time.
-A human ask and a credential rejection keep their own observed reason.
-
-| Observed reason | Codex `codexErrorInfo` | Claude `StopFailure.error` |
-| --- | --- | --- |
-| `usageLimit` | `usageLimitExceeded`, `rateLimitExceeded`, `sessionBudgetExceeded` | `rate_limit` |
-| `serverOverloaded` | `serverOverloaded` | `overloaded` |
-| `contextWindow` | `contextWindowExceeded` | `max_output_tokens` |
-| `connection` | `httpConnectionFailed`, `responseStreamConnectionFailed`, `responseStreamDisconnected`, `responseTooManyFailedAttempts` | — |
-| `policy` | `cyberPolicy` | `oauth_org_not_allowed` |
-| `account` | — | `account_on_hold`, `billing_error` |
-| `rejected` | `badRequest`, `activeTurnNotSteerable` | `invalid_request`, `model_not_found` |
-| `internal` | `internalServerError`, `threadRollbackFailed`, `sandboxError` | `server_error` |
-| `unclassified` | `other`, missing, unknown or unreadable cause | `unknown`, missing or unknown cause |
-
-Codex object variants carry the error word as their single key. A notification
-missing its required identity or retry fields proves nothing. A standing turn
-failure clears only on a successful matching completion, an idle thread, or a
-new turn starting. A failed completion and silence leave it standing. Claude's
-turn diagnostic clears only on `Stop`; `SessionStart` proves no recovery.
-
-No driver borrows the word for a neighbouring class: Claude's `rate_limit`,
-`overloaded`, `oauth_org_not_allowed`, `account_on_hold` and `billing_error`,
-Codex's `usageLimitExceeded` and `rateLimitExceeded`, and omp's `UsageLimit`,
-`AccountPolicy` and `Transient` flags are capacity, policy, or account state
-that a re-login cannot fix. Claude's `StopFailure` writes `idle` with a
-classified reason for them, because the turn ended. Codex preserves its
-delivery state and names a standing error in the observation's reason. A quota
-or model-capacity rejection remains retryable `idle`; other terminal failures
-remain `ended`. omp's frame writes `active` with omp's own bounded prose,
-which is the only place a reader learns that a 403 was about credits. The Codex
-startup gate pins `unauthorized` and both quota words present in
-`CodexErrorInfo`, so a release that merged them refuses the launch instead of
-letting st2 report an exhausted allowance as a rejected credential; omp needs no
-such gate because its flags are separate bits that cannot merge, but it does
-need the `Class` bit checked, because an unclassified `errorId` is a bare HTTP
-status. Because these three publish only on rejection, an absent record is their
-healthy steady state and Doctor advises nothing for it; OpenCode, which resolves
-its version gate on every launch, still advises on absence.
-
-The roster projection always has one fixed shape. `failure` fills every
-evidence field; `absent` and `indeterminate` preserve the same keys with null
-evidence and stable reader recovery text:
-
-```json
-"driverDiagnostic": {
-  "status": "failure | absent | indeterminate",
-  "driver": "opencode | null",
-  "stage": "readBack | null",
-  "reason": "notDurable | malformedRecord | unsupportedSchema | unknownVocabulary | futureSkew | null",
-  "source": "messageReadBack | null",
-  "producerVersion": "1.18.19 | null",
-  "support": "supported | unsupported | unknown",
-  "observedAt": 1787690300000,
-  "evidenceAgeMs": 250,
-  "recovery": "clearsOnStageRecovery | publishFailureOrClearOnStageRecovery | replaceWithValidRecordOrClearOnStageRecovery"
-}
-```
-
-Doctor consumes the same `Observed` value and `repair_text` function for
-declarations whose native driver is expected to publish this record (OpenCode
-in this version). It emits an advisory for `failure`, `absent`, and
-`indeterminate`; none changes Doctor's exit status. Roster retains the
-explicit object for every declaration.
-
-## Exposure (OHS-R09, OHS-R10, OHS-R14)
-
-`st2 agents --json` (both forms) appends one field per row:
-
-```json
-"observedState": {
-  "state": "active",
-  "blockedOn": "human",
-  "inputBuffer": "unknown",
-  "ask": "permission",
-  "harness": "codex",
-  "since": 1787690000000,
-  "reason": "waitingOnApproval",
-  "exit": null
-}
-```
-
-`null` when no record exists. The derivation above is already applied — a
-consumer never re-implements staleness. Roster reads pass the same-host
-liveness probe only for agents whose resolved host is this host, resolving
-the pty root exactly as the runner does (`PTY_ROOT`, else the catalog's own
-pty root; the legacy `PTY_SESSION_DIR` is deliberately not honored — the
-runner never uses it, and probing a directory st2-managed sessions never
-touch turns provable deaths into indeterminate reads). `status`,
-`desiredState`, and `lastActivity` keep their exact meanings; the three
-full-string pinned assertions and the stable-roster invariant wording are
-updated deliberately in the change that adds the field. Doctor prints an
-advisory (not a failure) for an owned agent whose record is stale,
-session-dead, or `ended` while desired state is `running`.
-
-## Verification plan
-
-The invariant rows this subsystem must add or amend when implementation lands,
-each only once a real test proves it (per `CLAUDE.md`):
-
-- **Scoped delivery-input watching** — a write to `harness-state` does not
-  wake the Codex delivery pump; an inbox write still does. Test in the shape
-  of `src/ding/mod.rs::idle_ding_does_not_spin_on_its_own_inbox_reads`.
-- **Stable roster JSON** (existing row) — wording gains the third axis;
-  `src/agents.rs::agents_json_has_stable_wire_shape` is edited in the same
-  change and stays the proof.
-- **Observed harness state discipline** — derived-only `unknown` with distinct
-  reasons, byte-distinct writes, no-mtime staleness, terminal-write-before-
-  escalation. Proving tests live in `src/harness_state.rs` today (11 tests)
-  plus the planned per-producer suites; the SIGKILL-mid-turn test (`ended`,
-  not `active`) gates the teardown row.
-- **Native-driver diagnostic discipline** — exhaustive closed vocabulary,
-  wrong-pair/unknown/malformed/additive decoding, stage-priority recovery,
-  OpenCode delivery/read-back recovery, exact roster wire, Doctor agreement,
-  and bounded telemetry labels are proved by focused unit/integration tests in
-  `src/driver_diagnostic.rs`, `src/opencode_session.rs`, `src/agents.rs`,
-  `src/metrics.rs`, and `tests/doctor.rs`.

-# All three signals via a three-PR gh stack
-
-Status: accepted
-
-Recorded 2026-08-25 from the aligned observability interview (axe decision catalog Q1 + Q3).
-
-## Context
-
-st2 needs OpenTelemetry instrumentation, but scope and delivery were open:
-
-- **Scope**: traces only (the classic first step), or all three OTel signals?
-- **Delivery**: one large PR, or a stack?
-
-Arguments for traces-first: smallest diff, fastest feedback, metrics/logs can wait. Arguments for
-one PR: single review surface. Against both: the exporter/provider plumbing is the hard part and
-is shared by every signal; once it lands, metrics and logs are incremental. Deferring them
-invites "traces shipped, rest never happens" — and the CI proof obligation (otelite capture +
-assertions) is signal-generic anyway.
-
-## Evidence and Argument
-
-The exporter/provider plumbing and otelite capture harness are shared across all three signals,
-while rates/durations require metrics and correlated diagnostics require logs. Splitting delivery
-at signal boundaries isolates review and CI failures without treating traces as the finished scope.
-
-## Decision
-
-**Q1 — Scope**: all three signals (traces, metrics, logs) are the target. Not traces-only; not
-traces-first-with-maybe-later.
-
-**Q3 — Delivery**: a gh stack of three PRs:
-
-1. SDK init + OTLP/HTTP-JSON exporter + trace spans (+ this VRS tree);
-2. metrics;
-3. log bridge.
-
-Each PR lands green independently; 2 and 3 build on 1's shared plumbing
-(provider/resource/exporter) only.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| All three signals in a three-PR stack | Selected | Shares the risky plumbing while isolating signal-specific review and CI failures. |
-| Traces first, defer the rest | Rejected | Defers rates, durations, and correlated diagnostics without reducing exporter risk. |
-| Single PR | Rejected | Couples all instrumentation sites and the capture harness into one blocking review surface. |
-| Spool files instead of direct OTLP | Rejected | Adds rotation, retention, and crash-safety machinery for a pipeline the fleet already provides. |
-
-## Consequences
-
-- The done-condition (CI-proven signals, zero-overhead no-op, unit env propagation, complete VRS
-  tree) is fully met only after PR3; PR1 alone meets it for traces.
-- Reviewers see plumbing once, then small incremental slices.
-- The stack order fixes the open-question deadlines: metric set must settle before PR2 opens, log
-  bridge approach before PR3 ([open questions](../open-questions.md)).

-# Numbered subsystem under st2's VRS root, referencing dotfiles' central tree
-
-Status: accepted
-
-Recorded 2026-08-25 from the aligned observability interview (axe decision catalog Q2).
-
-## Context
-
-Observability semantics could live in three places:
-
-1. A numbered subsystem directory under st2's existing `docs/vrs` root, alongside
-   [01-ding](../../01-ding/) through [05-harness-state](../../05-harness-state/).
-2. A standalone documentation root inside st2, separate from the VRS hierarchy.
-3. Only in the fleet-wide dotfiles context `observability` tree, with st2 documenting nothing of
-   its own.
-
-Fleet-wide naming/provenance rules and producer obligations genuinely belong to dotfiles'
-central tree (`01-conventions`, `09-integration/spec.md`). But st2-specific decisions — crate
-feature set, trace roots in `src/run.rs`, unit env propagation — have no home there and would be
-invisible to anyone working in this repo.
-
-## Evidence and Argument
-
-The repository already uses numbered VRS subsystems for product-specific lifecycle contracts,
-while the dotfiles observability tree owns fleet-wide semantics. A local subsystem with explicit
-central references preserves both contributor locality and one authority per shared rule.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Numbered st2 subsystem | Selected | Keeps local mechanisms and evidence beside their code while referencing central rules. |
-| Standalone st2 documentation root | Rejected | Duplicates the established VRS hierarchy. |
-| Central dotfiles tree only | Rejected | Leaves st2-specific crate, process, and CI decisions without repository-local authority. |
-
-## Decision
-
-This tree is a **numbered subsystem under st2's existing `docs/vrs` root**: `06-observability`
-(Q2). It follows the established subsystem shape — requirements/spec/open-questions plus `.decisions/`
-and `.experiments/`.
-
-Fleet-wide semantics stay owned centrally by dotfiles context `observability` (`01-conventions`
-for naming/provenance/span-label rules; `09-integration/spec.md` for the six producer
-obligations). This tree **references them and does not duplicate them**: it defines only what is
-st2-side — registered span/metric names, concrete `service.name` values, the crate stack, and the
-CI proof strategy. Central obligations that remain cross-repo work (registry entry, dashboard,
-census subject) are named explicitly as deferred in O11Y-R08 rather than restated here.
-
-## Consequences
-
-- st2 contributors find their telemetry contract next to the code it describes, in the same
-  conventions as every other subsystem.
-- One authority per rule: central rules are cited, never copied; drift between fleet convention
-  and st2 usage shows up as a broken reference, not divergent prose.
-- Renumbering risk exists if another subsystem claims 06 first; the number carries no meaning
-  beyond ordering, so a rename is mechanical.

-# Blocking HTTP-JSON exporter, single-client feature set, explicit flush at exit
-
-Status: accepted
-
-Recorded 2026-08-25 from the aligned observability interview, backed by prototype evidence
-([../.experiments/2026-08-25-rust-to-otelite-capture.md](../.experiments/2026-08-25-rust-to-otelite-capture.md)).
-
-## Context
-
-The exporter design had to satisfy four constraints simultaneously:
-
-- Fleet pipeline is **OTLP/HTTP JSON only** — no gRPC clients anywhere.
-- st2's process model is **synchronous**: there is no tokio reactor in the supervisor or CLI.
-- Telemetry must be a **zero-overhead no-op** when `OTEL_EXPORTER_OTLP_ENDPOINT` is unset.
-- Spans from short-lived CLI runs must actually arrive — batched exports die with the process if
-  nobody flushes.
-
-Two traps surfaced during prototyping:
-
-1. **The feature-interaction trap.** `opentelemetry-otlp` 0.30 with *both* `reqwest-client` and
-   `reqwest-blocking-client` enabled (the defaults include blocking) compiles cleanly but fails
-   at runtime with `NoHttpClient`: all three client-selection cfg arms require the absence of the
-   other client feature. The failure appears only when the first span exports.
-2. **The async-batch trap.** The default async batch exporter requires a tokio runtime; under
-   st2's sync process model it panicked at export time.
-
-## Evidence and Argument
-
-The linked otelite prototype exported real OTLP/HTTP JSON from a synchronous Rust process only
-with the blocking client and an exclusive reqwest-client feature selection. It reproduced both
-the dual-client `NoHttpClient` failure and the async exporter's missing-reactor panic, and proved
-that explicit shutdown delivers short-lived spans.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Blocking HTTP-JSON with one reqwest client feature | Selected | Proven end to end in the synchronous process model. |
-| Async HTTP client/batch runtime | Rejected | st2 has no tokio reactor and the prototype panicked at export time. |
-| Default or dual reqwest client features | Rejected | Compilation succeeds but exporter construction fails with `NoHttpClient`. |
-| gRPC | Rejected | The fleet ingestion contract is OTLP/HTTP JSON only. |
-
-## Decision
-
-st2 uses `opentelemetry-otlp` 0.30 with `default-features = false` and exactly
-`features = ["http-json", "reqwest-blocking-client", "internal-logs"]`. Exactly one reqwest
-client feature is ever enabled.
-
-The blocking client backs the **batch exporter**, with explicit `force_flush` + `shutdown`
-registered at process exit so short-lived CLI spans reach the collector.
-
-Endpoint configuration stays ambient: the exporter resolves `OTEL_EXPORTER_OTLP_ENDPOINT` itself,
-and init checks it once before installing any SDK object — unset means no provider, no threads,
-no allocation (O11Y-R02).
-
-## Consequences
-
-- No tokio dependency is pulled into st2's runtime path for telemetry.
-- The compile-clean/runtime-dead feature combination is structurally excluded by pinning the
-  exact feature list in `Cargo.toml`; any future feature addition must re-check the cfg-arm
-  interaction.
-- Export happens on st2's own threads via the blocking client; a slow local Alloy forwarder can
-  stall an exporting thread up to the client timeout. Accepted for now — the forwarder is
-  loopback-local; revisit only if real stalls appear.
-- `internal-logs` keeps exporter failures diagnosable instead of silently dropped.

-# Semantic reconcile trace hierarchy
-
-Status: accepted
-
-Recorded 2026-08-26 from the PR3 otelite hierarchy proof
-([../.experiments/2026-08-26-otelite-reconcile-hierarchy.md](../.experiments/2026-08-26-otelite-reconcile-hierarchy.md)).
-
-## Context
-
-PR3's tracing-facade migration exported exactly one `st2.reconcile_pass` span. The span correlated
-logs and carried final pass counts, but the trace remained flat: a slow or failing pass could not
-show whether catalog locking, desired-state discovery, hook verification, materialization, runtime
-observation, or runner mutation owned the time or failure. Function-level instrumentation would
-make that question worse by exposing planning and wrapper structure rather than reconciliation
-semantics.
-
-The hierarchy must preserve the existing root and control flow, remain bounded per pass, obey the
-central non-empty `span.label` and cardinality contract, and construct no child telemetry when the
-tracer exporter is absent even though the stderr tracing subscriber is always installed.
-
-## Evidence and Argument
-
-The linked otelite capture proves the flat baseline can become one root plus five direct,
-same-trace children on an empty catalog without changing the existing metric/log assertions.
-Reading the reconciliation lifecycle identifies exactly six external operation boundaries; all
-other candidate seams are pure planning, bookkeeping, wrappers, or unbounded per-task detail.
-
-## Decision
-
-Keep `st2.reconcile_pass` as the compatibility root and add only aggregate direct children at real
-I/O or mutation boundaries:
-
-- `st2.catalog.lock`
-- `st2.catalog.discover`
-- `st2.hooks.verify`, only when verification is required
-- `st2.catalog.materialize`
-- `st2.runtime.observe`, only for an authoritative in-pass `Runner::list_sessions`
-- `st2.reconcile.execute`
-
-Every span has a bounded, public `span.label`. Attributes contain bounded enums and counts only;
-ids, paths, selectors, and error prose are excluded. A child gets OTel `ERROR` status when its
-boundary fails or reports errors; the root gets `ERROR` when the pass fails. All child constructors
-early-return behind the tracer-export-enabled `AtomicBool`, not `tracing::enabled!`. Children are
-always direct root children, never nested by incidental call structure.
-
-## Options
-
-| Option | Result | Reason |
-| --- | --- | --- |
-| Bounded semantic aggregate children | Selected | Locates lifecycle latency/failure while keeping one fixed detail budget. |
-| Flat root only | Rejected | Cannot locate latency or failure within a reconcile pass. |
-| Function-mirroring spans | Rejected | Exposes implementation structure rather than external work. |
-| Unbounded per-task or per-owner spans | Rejected | Volume and cardinality scale with catalog and mutation size. |
-
-
-### Flat root only
-
-Rejected. It preserves minimum volume but cannot locate latency or failure within a reconcile
-pass; the trace adds little beyond the correlated completion log.
-
-### Function-mirroring spans
-
-Rejected. Spans for validation, planning, compilation, debounce, wrappers, watcher callbacks,
-and report absorption would expose implementation structure, inflate volume, and make refactors
-look like telemetry contract changes without representing additional external work.
-
-### Unbounded per-task or per-owner spans
-
-Rejected for this hierarchy. They may diagnose individual runner operations but cardinality and
-volume scale with catalog size and mutation count. Such detail requires a separately specified hard
-budget and privacy/cardinality review before adoption.
-
-## Consequences
-
-- One pass exports at most the fixed aggregate set; hook verification and external-snapshot
-  observation are truthfully omitted when not performed.
-- Grafana can attribute pass duration and error status to lifecycle boundaries without querying
-  error strings.
-- The empty-catalog otelite test proves one root, five direct children, shared trace identity,
-  exact parent ids, and non-empty labels.
-- Detail below aggregate execution remains unavailable by design; a future per-task proposal must
-  define and prove its own bound rather than extending this decision implicitly.

-# Rust sync exporter to otelite capture, proven end-to-end
-
-2026-08-25. Prototype run by the parent agent before implementation begins. Question, method, and
-result recorded here so PR1's crate choices rest on evidence, not hope.
-
-## Question
-
-Can a synchronous Rust program using `opentelemetry-otlp` 0.30 export spans over OTLP/HTTP JSON
-into an `otelite` capture receiver — without a tokio runtime — and can the result be asserted
-with `inspect`? Which crate feature set actually works?
-
-## Method
-
-A minimal sync Rust program:
-
-- `opentelemetry` + `opentelemetry-sdk` + `opentelemetry-otlp`, HTTP-JSON wire;
-- two spans emitted under distinct `service.name` resource values;
-- ambient `OTEL_EXPORTER_OTLP_ENDPOINT` pointed at a local `otelite capture` instance.
-
-Receiver: `otelite` (`@overeng/utils-dev/otelite` on effect-utils main, exposed as the
-effect-utils flake package output `otelite`) — native axum/tonic OTLP receiver accepting
-`/v1/{traces,metrics,logs}` in JSON and protobuf from any process. Capture mode runs
-receiver-only until SIGINT/SIGTERM/stdin EOF; `inspect` summarizes and asserts on the capture.
-
-## Result
-
-- Both spans were received over HTTP JSON into the capture; `otelite inspect` showed them grouped
-  by `service.name`. End-to-end path proven: Rust sync → otlp 0.30 → HTTP JSON → otelite.
-- The ambient-endpoint contract holds: the program set no endpoint in code; exporter resolution
-  picked up `OTEL_EXPORTER_OTLP_ENDPOINT`.
-
-### Finding 1: the NoHttpClient feature trap
-
-`opentelemetry-otlp` 0.30 with **both** `reqwest-client` and `reqwest-blocking-client` features
-enabled compiles cleanly and fails at runtime with `NoHttpClient`. Cause: all three client-
-selection cfg arms require the *absence* of the competing client feature, so no client is ever
-constructed. Defaults include blocking alongside async, so the naive dependency line hits this.
-
-Working feature set (the one PR1 pins):
-
-```
-default-features = false, features = ["http-json", "reqwest-blocking-client", "internal-logs"]
-```
-
-### Finding 2: async batch export needs a reactor
-
-The default async batch exporter panicked under st2's sync process model — there is no tokio
-reactor to drive it. The blocking client + batch exporter combination works. Consequence carried
-into [decision 0003](../.decisions/0003-blocking-http-json-exporter.md): blocking client chosen,
-with batch exporter plus explicit `force_flush`/`shutdown` at exit.
-
-### Caveat: otelite capture stdin EOF kills it
-
-`otelite capture` treats **stdin EOF as termination**. A test harness spawning capture with
-stdin closed or `/dev/null` loses the receiver mid-test. The planned cargo integration tests must
-hold the child's stdin open (held-open pipe) until the capture window ends. Recorded in the
-[specification](../spec.md#testing-strategy).
-
-
-## Conclusion
-
-A synchronous Rust program exports spans end-to-end into an `otelite` capture receiver over
-OTLP/HTTP JSON with no tokio runtime, and `otelite inspect` asserts on them grouped by
-`service.name`. Two constraints are load-bearing: exactly one reqwest client feature may be
-enabled (the both-features combination compiles but dies with `NoHttpClient` at export time),
-and the batch exporter must be driven by the blocking client since there is no reactor. A test
-harness must also hold the capture child's stdin open — EOF terminates it mid-test.
-
-## VRS Impact
-
-- Evidence behind [decision 0003](../.decisions/0003-blocking-http-json-exporter.md) and
-  requirement O11Y-R07 (sync process model): blocking client + batch exporter + explicit flush
-  at exit is the proven configuration, pinned verbatim in the [specification](../spec.md).
-- Ambient-endpoint resolution confirmed for O11Y-R02 before any code was written.
-- The stdin-EOF caveat is recorded in the specification's testing strategy and is baked into
-  the integration-test harness design. Metrics/logs ingestion remains unproven until PR2/PR3;
-  no requirement text changes.
-
-## Limits
-
-- Prototype exercised traces only; metrics and log ingestion through the same receiver are
-  untested until PR2/PR3 (otelite accepts all three endpoints, but assertions must be proven).
-- Single-run evidence; the CI integration tests are themselves the durable reproduction, which is
-  why R03 makes them part of the done-condition.

-[decision 0004](../.decisions/0004-semantic-reconcile-trace-hierarchy.md).
-
-## Question
-
-One real `st2 up --catalog <empty> --once` invocation can export a non-flat reconcile trace over
-OTLP/HTTP JSON while retaining exactly one compatibility root, one metric set, and one correlated
-completion log. Every semantic child should be a direct root child with the same trace id and a
-non-empty bounded `span.label`.
-
-## Method
-
-Ran the repository integration test against the flake-provided real `otelite` receiver:
-
-```console
-nix develop -c cargo test --test otel_export -- --nocapture
-```
-
-The test launches the real `st2` binary through `otelite run --protocol http/json`, supplies an
-empty catalog, decodes `traces.ndjson`, `metrics.ndjson`, and `logs.ndjson`, and asserts ids and
-attributes from the raw OTLP export request rather than an in-memory tracing subscriber.
-
-## Result
-
-The command passed both integration tests (`2 passed; 0 failed; 0 ignored`). The exported trace
-for the endpoint-enabled invocation contained exactly six spans:
-
-```text
-st2.reconcile_pass             span.label=catalog
-├── st2.catalog.lock           span.label=shared
-├── st2.catalog.discover       span.label=catalog
-├── st2.catalog.materialize    span.label=catalog
-├── st2.runtime.observe        span.label=all sessions
-└── st2.reconcile.execute      span.label=apply plan
-```
-
-The decoded/raw assertions proved:
-
-- exactly one `st2.reconcile_pass` root;
-- every listed child occurred exactly once;
-- every child's `parentSpanId` equaled the root `spanId`;
-- every child's `traceId` equaled the root `traceId`;
-- every root and child had a non-empty `span.label`;
-- `st2.hooks.verify` was absent because an empty catalog has no hook consumer;
-- the pre-existing one reconcile counter point, one reconcile duration sample, one completion log
-  correlated to the root trace/span ids, and no `BatchLogProcessor.Emit.AfterShutdown` assertions
-  remained green;
-- the endpoint-unset invocation completed and left traces, metrics, and logs absent or empty.
-
-## Conclusion
-
-The aggregate semantic hierarchy is visible in real OTLP output, direct parentage is stable, and
-conditional omissions represent operations that did not occur. The same test is the durable CI
-reproduction required by O11Y-R03.
-
-## VRS Impact
-
-The hierarchy, labels, attributes/status rules, path applicability, rejected spans, and disabled
-construction guard are normative in [the specification](../spec.md#reconciliation-trace-hierarchy).
-No requirement text changes: the evidence strengthens O11Y-R01, O11Y-R02, and O11Y-R03 without
-changing their scope.

-# Observability open questions

-Kept minimal; each blocks exactly one delivery slice, not the tree.
-
-- **PR2 metric set.** Landed: the RED-minimal set from interview decision Q5, with names,
-  types, and label enums as specified in [spec.md](spec.md) (`src/metrics.rs`); the
-  `st2 up <spec>` span coverage folded in as planned — all three reconcile-pass sites now
-  emit `st2.reconcile_pass` plus the pass counter and duration histogram.
-- **Remaining R04 resource attributes.** Resolved by source read (dotfiles dev3
-  `monitoring.nix` transform block): the platform edge stamps `service.namespace`,
-  `sk.site`, `sk.role`, `deployment.environment.name` where absent, and the central
-  contract forbids hand-stamping them producer-side. st2 keeps `service.name`,
-  `service.version`, `host.name`; nothing left to wire.
-- **PR3 log bridge approach.** Resolved by interview (decision record Q6) and LANDED: the
-  `tracing` facade (`tracing-opentelemetry` + `opentelemetry-appender-tracing`) unifies spans
-  and logs on one subscriber; emit sites migrated to tracing macros; the unset-endpoint case
-  keeps the stderr fmt layer so diagnostics stay visible (documented deviation from PR1's
-  zero-output reading). Larger diff accepted for the long-term win; PR1's dual-path helper is
-  not built.
-- **Unit env mechanism.** Resolved at PR1 implementation time: `Environment=` lines,
-  captured at install time and unit-tested (`src/service.rs`); matches the existing
-  PATH/PTY_ROOT pattern and the expected handful of variables. Revisit
-  `EnvironmentFile=` only if the variable count grows.
-- **Sampling.** Default is always-on given st2's low event volume. If supervisor-loop span volume
-  proves noisy in Grafana, revisit parent-based sampling ratios — not before there is data.

-# Observability requirements
-
-st2 and st3 emit OpenTelemetry signals about their own supervision work. This tree defines what
-their telemetry must do and how it is proven. It follows the root [vision](../vision.md) and refines the
-supervision subjects of the root [requirements](../requirements.md). It does not define fleet-wide
-naming, provenance, or pipeline semantics — those are owned centrally by the dotfiles context
-`observability` tree (`01-conventions` for naming/provenance/span-label rules, `09-integration`
-for producer obligations, `otel-stack.md` for the LGTMP pipeline), which this tree references.
-
-## Context
-
-Until PR1, st2 had zero telemetry: no `tracing`, logging, or opentelemetry dependencies in
-`Cargo.toml`, and diagnostics were bare `println!`/`eprintln!`. PR1 introduces trace export
-([specification](spec.md)); metrics (PR2) and the log bridge (PR3) are still open. Durable
-records — events, the sent ledger,
-harness-state ([05-harness-state](../05-harness-state/)) — capture *what happened* but not *how
-long it took*, *how often*, or *in what order across processes*. A supervisor that wedges in a
-reconcile pass or a hung provider-session probe is invisible until a human reads a log file.
-
-The fleet already runs an OTLP pipeline: producers ship OTLP/HTTP JSON to a per-host Alloy
-forwarder at `127.0.0.1:4318`, which forwards to dev3 LGTMP and Grafana/gcx. st2 joins that
-pipeline as one more producer; it does not invent its own.
-
-## Requirements
-
-### st2
-
-- **O11Y-R01 Three signals:** st2 produces traces, metrics, and logs through OpenTelemetry.
-  Traces cover the supervision control flow (roots listed in the
-  [specification](spec.md)); metrics cover rates and durations of recurring passes;
-  logs replace ad-hoc diagnostics on the paths where correlation matters. All three is the target,
-  not traces alone.
-- **O11Y-R02 No-op when unset:** Signals are emitted only when `OTEL_EXPORTER_OTLP_ENDPOINT` is
-  set. When unset, telemetry is a zero-overhead no-op: no exporter threads, no network calls, no
-  measurable cost on hot loops. Ambient configuration is honored automatically by exporter
-  resolution. No proprietary st2 configuration surface exists beyond standard `OTEL_*` variables.
-- **O11Y-R03 CI-proven:** The done-condition is proven in CI, not asserted. Integration tests run
-  st2 against an `otelite` capture receiver and assert emitted spans/signals via its inspect
-  mode. A build whose telemetry regresses to silence fails CI.
-- **O11Y-R04 Provenance:** Every exported signal carries the fleet resource-attribute set:
-  `service.name`, `service.namespace`, `service.instance.id`, `host.name`, `sk.site`, `sk.role`,
-  and `deployment.environment.name`. Registered names are defined st2-side (this tree), not
-  borrowed. `service.version` derives from the build stamp (`src/version.rs` reading
-  `CLI_BUILD_STAMP`), the same identity the fleet `cli-version` shape carries.
-- **O11Y-R05 Service naming by process unit:** `service.name` names the st2 process unit, not the
-  repo — e.g. `st2-supervisor`, `st2-cli`, `st2-hook` — so a Grafana query groups a supervisor's
-  lifetime separately from one-shot CLI invocations, per the central `01-conventions` rules.
-- **O11Y-R06 Unit environment propagation:** The systemd supervisor unit propagates the
-  operator's `OTEL_*` environment into the service: `src/service.rs` serializes the `OTEL_*`
-  variables present in the launching environment into `Environment=` lines alongside the
-  existing `PATH`/`PTY_ROOT` serialization, so `st2 up --install-unit` preserves ambient
-  telemetry configuration (R02) under systemd.
-- **O11Y-R07 Sync process model (st2 only):** Telemetry must not require an async runtime. st2's
-  process model is synchronous (no tokio reactor); the exporter path must work under blocking clients.
-- **O11Y-R08 Conformance posture:** Fleet-integration obligations are met as far as the st2 side
-  allows: resource attributes (R04), naming (R05), OTLP endpoint via ambient env (R02). The
-  remaining central obligations — the `telemetry.contract.ts` registry entry, the Grafana
-  dashboard, and coverage-census subject registration — live in dotfiles' central observability
-  tree and are explicitly deferred as cross-repo follow-up work, not part of st2's delivery.
-- **O11Y-R09 Native-driver diagnostics:** Native-driver diagnostic
-  failure/recovery transitions emit a bounded span/event and counter. The only
-  metric-label axes are closed stage, reason, source, support, and outcome
-  vocabularies. `span.label` is the bounded stage. Raw producer versions and
-  agent/runtime/session/message identity are forbidden from metrics and
-  `span.label`; raw prompt, message, and path content is forbidden from every
-  diagnostic signal.
-
-### st
-
-The current O11Y-R10–R18 constraints and mechanism are in
-[st observability](../../st3/observability.md).

-# Observability specification
-
-This document owns the mechanism behind [requirements](requirements.md): the crate stack, exporter
-configuration, span roots, unit propagation, test strategy, and delivery order. Naming,
-provenance, and span-label rules are referenced from the dotfiles context `observability` tree
-(`01-conventions`); the six producer obligations from its `09-integration` spec. st2-side
-obligations land here; registry/dashboard/census obligations are deferred cross-repo
-(O11Y-R08).
-
-## Crate stack
-
-```
-opentelemetry                   = "0.30"
-opentelemetry_sdk               = { version = "0.30", features = ["logs"] }
-opentelemetry-otlp              = { version = "0.30", default-features = false,
-                                    features = ["http-json", "reqwest-blocking-client",
-                                                "internal-logs", "logs"] }
-# tracing facade (PR3) — spans and logs unify on one subscriber
-tracing                         = "0.1"
-tracing-subscriber              = "0.3"
-tracing-opentelemetry           = "0.31"
-opentelemetry-appender-tracing  = { version = "0.30",
-                                    features = ["experimental_use_tracing_span_context"] }
-```
-
-The appender-tracing `experimental_use_tracing_span_context` feature is load-bearing: without
-it, emitted log records do not receive the active tracing span's trace/span ids and every
-record exports uncorrelated.
-
-The otlp feature set is load-bearing, not stylistic:
-
-- **No gRPC client.** The fleet pipeline is OTLP/HTTP JSON only (`otel-stack.md`); no gRPC clients
-  anywhere.
-- **Blocking reqwest client only.** With both `reqwest-client` and `reqwest-blocking-client`
-  enabled (the defaults include blocking alongside async), the crate compiles but every runtime
-  client-selection cfg arm requires *not*-having the other feature, so export fails with
-  `NoHttpClient` at span-export time. Exactly one of the two must be enabled.
-- **Blocking chosen over async** because st2 has no tokio reactor; the async batch exporter
-  panicked without one. See the prototype evidence
-  ([.experiments/2026-08-25-rust-to-otelite-capture.md](.experiments/2026-08-25-rust-to-otelite-capture.md)).
-- **`internal-logs`** keeps exporter-internal errors observable instead of swallowed.
-
-## Exporter and provider setup
-
-One module, `src/telemetry.rs`, owns init and teardown via `Telemetry::init(unit)` /
-`Telemetry::shutdown()`:
-
-- **Endpoint**: none configured in code. The exporter resolves `OTEL_EXPORTER_OTLP_ENDPOINT` and
-  related `OTEL_*` variables from the environment automatically. Unset → no SDK provider or
-  exporter is built (R02); since PR3 the human-readable stderr `tracing` layer still runs so
-  diagnostics stay visible — see [Log bridge](#log-bridge-pr3-landed).
-- **Protocol**: HTTP JSON (`http-json` + protobuf-free wire), batch exporter, targeting the local
-  Alloy forwarder at `127.0.0.1:4318` by convention.
-- **Resource**: `service.name` = `st2-<unit>` selected per entrypoint (below; `src/main.rs`
-  passes `supervisor`, `hook`, or `cli`), `service.version` from `crate::version::machine_version`, and
-  `host.name` from the existing host detection. The remaining R04 fleet attributes
-  (`service.namespace`,
-  `service.instance.id`, `sk.site`, `sk.role`, `deployment.environment.name`) are not set yet —
-  tracked as an [open question](open-questions.md).
-- **Flush/shutdown**: `force_flush` + global `shutdown` registered to run at process exit. The
-  batch exporter buffers; without explicit flush at exit, tail spans of short-lived CLI runs are
-  lost. This pairing is required for delivery, not optional.
-
-### service.name values (R05)
-
-| Process unit | `service.name` |
-| --- | --- |
-| Supervisor loop (`st2 up` daemon / systemd unit) | `st2-supervisor` |
-| One-shot CLI invocations | `st2-cli` |
-| Hook executions (`st2 driver claude-observe`; other hook surfaces not instrumented yet) | `st2-hook` |
-| Claude's status-line tee (`st2 driver claude-statusline`) | **none — no pipeline is built** |
-
-**The one deliberate exemption, and the rule behind it.** A subcommand whose cadence is set by a
-harness's refresh timer rather than by an operator or an event does not initialize the telemetry
-pipeline at all (`Telemetry::local_only`). Claude's status-line tee is the only such surface
-today: `refreshInterval: 5` makes it ~720 short-lived processes per hour per seat, and Claude
-waits for each to exit, so the final collect-and-export at shutdown would sit in the render path.
-Measured against a bound-but-never-accepting collector, a tee that builds a pipeline takes 5.0 s
-on the path that logs and `claude-observe` takes 10.0 s, against 0.01–0.06 s with none
-(`08-harness-context`, `DQ-C13`).
-
-The rule is about **cadence, not about being a hook**: `claude-observe` is event-driven, is named
-in the table above, and stays instrumented. Anything added to the exempt list needs the same
-argument — a harness-driven repeat rate and no operation worth a span — not merely being a
-hook-set script.
-
-## Reconciliation trace hierarchy
-
-Instrumented exclusively through the `tracing` facade (`tracing::info_span!` plus
-`tracing-opentelemetry` status extension), one bounded trace represents one reconcile pass:
-
-```
-st2.reconcile_pass
-├── st2.catalog.lock
-├── st2.catalog.discover
-├── st2.hooks.verify                 # only when a consumer requires hooks
-├── st2.catalog.materialize
-├── st2.runtime.observe              # omitted for an externally supplied snapshot
-└── st2.reconcile.execute
-```
-
-`st2.reconcile_pass` remains the compatibility root at the supervisor-loop, one-shot catalog,
-selected-task, and single-file-spec sites. Its `span.label` and `st2.reconcile.path` are the enum
-`catalog | selected | spec`. Root outcome attributes are `st2.host`, `st2.crash_loops`,
-`st2.unparked`, `st2.report.errors`, `st2.report.warnings`, `st2.reconcile.skipped`, and
-`st2.result = pass | fail`; non-empty errors set OTel status `ERROR`. A deterministic INFO event
-(target `st2`, message `reconcile pass complete`, `result = pass | fail`) closes every root so
-log-based assertions need no fault injection.
-
-| Span name | Parent | `span.label` | Operation boundary | Attributes and status | Path applicability |
-| --- | --- | --- | --- | --- | --- |
-| `st2.reconcile_pass` | none | `catalog` \| `selected` \| `spec` | One complete reconcile pass | Root attributes above; `ERROR` when the pass returns/collects an error | Catalog loop/once, selected task, spec loop/once |
-| `st2.catalog.lock` | `st2.reconcile_pass` | `shared` | Shared catalog-authoring lock acquisition | `st2.result`; `ERROR` on acquisition failure | Catalog, selected |
-| `st2.catalog.discover` | `st2.reconcile_pass` | `catalog` | Recursive desired-state snapshot | `st2.catalog.spec_count`, report warning/error counts, `st2.result`; `ERROR` when discovery reports errors even though the pass may continue | Catalog, selected |
-| `st2.hooks.verify` | `st2.reconcile_pass` | `lifecycle hooks` | Required lifecycle-hook receipt/set verification | `st2.hooks.consumer = codex \| pi \| codex+pi`, `st2.result`; `ERROR` on verification failure | Catalog or selected, only when required |
-| `st2.catalog.materialize` | `st2.reconcile_pass` | `catalog` \| `selected owner` | Aggregate catalog/selected-owner materialization call | Materialization failure and report warning/error counts, `st2.result`; `ERROR` when materialization reports errors | Catalog, selected |
-| `st2.runtime.observe` | `st2.reconcile_pass` | `all sessions` | Authoritative `Runner::list_sessions` call | `st2.runtime.session_count`, `st2.result`; `ERROR` on list failure | Catalog, selected, spec; omitted by `_with_sessions` because that snapshot is external |
-| `st2.reconcile.execute` | `st2.reconcile_pass` | `apply plan` | Aggregate mutation call around `execute_with_presentation_cursor` | Plan launch/GC/teardown counts, newly added report warning/error counts, `st2.result`; `ERROR` only when execution adds errors | Catalog, selected, spec |
-
-Every first-party root and child has a non-empty `span.label`. The exporter-enabled
-`AtomicBool` in `src/telemetry.rs` is the hierarchy gate; `tracing::enabled!` is insufficient
-because the stderr formatter remains installed without an endpoint. When the tracer exporter is
-unset, child constructors return before span construction, label handling, collection allocation,
-or count inspection. All children are aggregates and trace volume is bounded by the table.
-
-Attribute policy follows the central `01-conventions` contract:
-
-| Attribute family | Value type | Cardinality | Privacy | Metric-label policy |
-| --- | --- | --- | --- | --- |
-| `span.label` | enum string | bounded | public | forbidden |
-| `st2.reconcile.path`, `st2.result`, `st2.hooks.consumer` | enum string | tiny/bounded | public | spanmetrics-only |
-| All `*_count`, `st2.crash_loops`, `st2.unparked`, `st2.report.errors`, `st2.report.warnings` | integer | bounded numeric | public | forbidden |
-| `st2.reconcile.skipped` | boolean | tiny | public | spanmetrics-only |
-| `st2.host` | string | bounded fleet identity | internal | forbidden |
-
-No span or status description carries an id, filesystem path, selector, or error prose.
-
-Explicitly rejected spans: pure reconcile planning, identity validation,
-`compile_generated_tasks`, debounce, report absorption, wait/sleep, watcher callbacks, and
-wrapper functions. Per-task and per-owner spans are also rejected from this hierarchy: they need
-a separately specified hard detail budget. Provider-session lifecycles and exec sidecars remain
-follow-up surfaces beyond the PR2 launch/reap counters.
-
-### Native-driver diagnostic transitions (O11Y-R09)
-
-`src/driver_diagnostic.rs` emits one `st2.driver.diagnostic` span plus its
-correlated `st2 native driver diagnostic transition` INFO event only when a
-typed failure tuple changes or recovers. `span.label` is the closed stage.
-Span/event attributes are `st2.driver.stage`, `st2.driver.reason`,
-`st2.driver.source`, `st2.driver.support`, and `st2.outcome`; the raw
-`st2.driver.producer_version` is span/log-only. No agent, runtime, session, or
-message id is needed on this transition, and no prompt/message/path value is
-recorded.
-
-The span's stage/reason/source/support/outcome attributes are the same closed
-values used by the counter below. Versions and identities are specifically not
-counter labels or `span.label`. With no trace exporter the span is not
-constructed; with no meter provider the counter returns before touching its
-instrument.
-
-## Metrics (PR2)
-
-Landed RED-minimal set per interview decision Q5; every label value comes from a bounded enum,
-and identifiers never become metric labels (ids stay in span attributes). `src/metrics.rs` owns
-the instruments; every record call early-outs unless a meter provider is installed.
-
-| Instrument | Type | Labels |
-| --- | --- | --- |
-| `reconcile_passes_total` | counter | `result` = `pass` \| `fail` |
-| `task_launches_total` | counter | `driver` = `codex` \| `claude` \| `opencode` \| `pi` \| `omp` \| `exec` \| `other` |
-| `task_reaps_total` | counter | `driver` (same enum as launches) |
-| `hook_invocations_total` | counter | `hook` = registry name (`claude-observe`), `event` = bounded Claude hook-event set, unknown → `other` |
-| `message_deliveries_total` | counter | `result` = `pass` \| `fail` |
-| `crash_loops_total` | counter | — |
-| `driver_diagnostic_transitions_total` | counter | `stage`, `reason`, `source`, `support`, `outcome = failure | recovery` (all closed enums) |
-| `resource_observe_requests_total` | counter | `outcome` = `accepted` \| `backpressured` \| `settledUnchanged` \| `settledChanged` \| `settledFailed` \| `absentBinding` \| `staleGeneration` \| `providerUnavailable` \| `other` |
-| `resource_observe_dispatch_seconds` | histogram | — |
-| `resource_observe_settle_seconds` | histogram | — |
-| `reconcile_pass_duration_seconds` | histogram | — |
-| `session_start_duration_seconds` | histogram | — |
-
-All duration histograms share seconds-scale explicit bucket boundaries
-`0.001`, `0.005`, `0.01`, `0.025`, `0.05`, `0.1`, `0.25`, `0.5`, `1`,
-`2.5`, `5`, and `10` (`DURATION_BUCKET_BOUNDARIES` in `src/telemetry.rs`)
-instead of the SDK's millisecond-tuned defaults. This keeps sub-second
-reconcile passes, spawns, observe dispatches, and settlements distinguishable.
-Observe metric statuses use the same camelCase durable-wire spelling; kebab-case
-is reserved for human CLI text.
-
-Scope notes: passes are counted at all three `st2.reconcile_pass` sites (catalog loop pass,
-one-shot up, and the single-file spec path — `reconcile_pass_specs_with_sessions`, which now
-emits the same root span shape); `fail` means the pass collected errors. Reaps count the
-restart path in the launch loop, where driver context exists. Deliveries cover bus deliveries
-onto a recipient inbox (`deliver_record`, send + retry paths); ding/native transport outcomes
-are separate follow-ups. Hook invocations are observed at the single in-process application
-point (`st2 driver claude-observe`); hook scripts the harnesses execute directly are not
-visible to st2. The `driver` label is a closed enum resolved by precedence: `exec` task kind
-first, then a typed driver declaration, then an observational argv/shell token heuristic
-(alphanumeric tokens matched in launch order: `codex`, `claude`, `opencode`, `omp`, `pi`; anything
-else → `other`). Because the heuristic inspects arbitrary user work, a hand-authored seat may
-be labeled by what its command line merely mentions — the label is diagnostic only and never
-influences reconcile decisions.
-
-The meter provider shares PR1's plumbing: `Telemetry::init` installs an `SdkMeterProvider`
-with a `PeriodicReader` + OTLP/HTTP-JSON metric exporter behind the same
-`OTEL_EXPORTER_OTLP_ENDPOINT` guard and resource; unset → no provider and the global meter is
-a silent no-op (R02 zero-overhead). `Telemetry::shutdown` force-flushes metric points alongside
-spans so short-lived CLI runs deliver them.
-
-## Log bridge (PR3, landed)
-
-Resolved by interview decision Q6: the `tracing` facade unifies spans and logs on one
-subscriber (`src/telemetry.rs`):
-
-- **stderr fmt layer — always installed.** Human-readable lines keep today's diagnostics
-  visible with or without an endpoint. This is a deliberate deviation from PR1's literal
-  zero-output unset-endpoint behavior: migrated `tracing` sites must not go silent. Level
-  filtering defaults to INFO; `RUST_LOG` overrides.
-- **Span layer** — `tracing-opentelemetry` exports spans through the existing tracer provider.
-- **Log bridge** — `opentelemetry-appender-tracing` exports events through a new SDK logger
-  provider sharing the endpoint, HTTP-JSON protocol, blocking client, and resource. With the
-  `experimental_use_tracing_span_context` feature, records emitted inside a span carry its
-  trace/span ids.
-
-`Telemetry::shutdown` force-flushes and shuts down logger, meter, and tracer providers together.
-
-Emission-site migration rule: non-user-facing diagnostics (`eprintln!` warn/error paths in
-crash-loop handling, park-channel setup, catalog watching, ding transport ambiguity, driver
-session degradation) became `tracing::warn!`/`error!` with unchanged message text. USER-FACING
-CLI OUTPUT STAYS `println!`/`eprintln!`: command results (`installed`, boot reports, `ls`
-tables), lock banners, and validation reports are interfaces, not diagnostics.
-
-## Systemd unit propagation
-
-`src/service.rs` builds the supervisor unit and serializes the operator's `OTEL_*` environment
-into `Environment=` lines alongside the existing `PATH`/`PTY_ROOT` serialization, so
-`st2 up --install-unit` preserves R02 (ambient endpoint) under systemd. Unit tests in
-`service.rs` extend the existing serialization assertions.
-
-## Testing strategy
-
-- **Integration tests** (`tests/otel_export.rs`, cargo integration tests): the receiver is a
-  prebuilt `otelite` binary passed by path via `ST2_OTELITE_BIN` (the effect-utils flake package
-  output; gate wiring supplies it, and a gate run hard-fails without it unless
-  `ST2_ALLOW_OTEL_SKIP=1` explicitly allows a local skip). Each test spawns
-  `otelite capture` on an ephemeral port (`--http-port 0`), points the binary under test at it
-  via `OTEL_EXPORTER_OTLP_ENDPOINT`, drives one command, then stops the receiver by closing its
-  stdin — EOF flushes the capture to disk — and asserts on the captured traces (span names,
-  resource attributes), metrics (PR2), and log records (PR3: the deterministic
-  `reconcile pass complete` INFO record must carry the `st2.reconcile_pass` span's trace/span
-  ids, proving tracing→OTel correlation end to end). Precedent: dotfiles op-proxy tests use
-  `captureEnvTrace`; dotfiles branchy checks consume
-  `effect-utils.packages.<system>.otelite`.
-  - Caveat baked into harness design: `otelite capture` treats stdin EOF as termination, so the
-    harness closes stdin deliberately as the stop signal rather than leaking `/dev/null`.
-- **No-op proof**: a test asserts that with `OTEL_EXPORTER_OTLP_ENDPOINT` unset, the command
-  completes normally with no export activity — guarding R02.
-- **Flake check wiring**: the check pulls effect-utils' `otelite` package output, mirroring the
-  branchy-check pattern, so CI proves R03 end-to-end without network access to dev3.

-## Delivery: gh stack of three PRs
-
-1. **PR1 — traces.** SDK init, OTLP/HTTP-JSON exporter with the exact feature set above, resource
-   attributes, trace roots, unit `OTEL_*` propagation, otelite-based integration tests and flake
-   check wiring, plus this VRS tree.
-2. **PR2 — metrics.** Metric set finalized per open questions; shares provider/exporter/resource
-   plumbing from PR1; otelite assertions extended to metrics.
-3. **PR3 — log bridge.** Landed per Q6: `tracing` facade adopted, spans and logs on one
-   subscriber; correlated diagnostics migrated; otelite assertions extended to logs.
-
-Each PR lands CI-green independently; PR2/PR3 depend on PR1's plumbing only.

-# omp harness integration surface
-
-## Question
-
-Does st2's pi-driver mechanism — an injected TypeScript extension speaking newline-delimited
-JSON frames over stdio to a channel process — port to omp, and what diverges? Sub-questions:
-which lifecycle events exist, when does omp become provably idle, does native delivery drive a
-real turn, and is there any waiting-on-human signal?
-
-Date: 2026-08-25. Binary: omp v18.0.3 (`omp` on dev3 PATH, Nix store
-`zv3xvic38a2gcdpxk3wd5fsk6plsgvbn-omp-18.0.3`). Linux x86_64, driven through live `omp`
-processes (print mode for API probes, a PTY-held interactive TUI for lifecycle and delivery
-runs).
-
-## Method
-
-
-Six throwaway TypeScript extensions, each loaded via `omp -e ./probeN.ts`, writing observations
-to files beside them. Print-mode runs used `--no-session --no-tools --no-lsp --no-skills
---no-rules`. Interactive runs held the TUI in a supervised PTY session and drove prompts by
-typing into the pane; one run forced approvals with `--approval-mode always-ask`.
-
-## Result
-
-**omp is pi-family.** omp reads pi's env fallbacks (`PI_SMOL_MODEL` documented in `--help`),
-loads pi-style default-export TypeScript extensions unchanged at the module boundary, and its
-extension first argument carries the same three calls st2's pi channel uses:
-`sendUserMessage(content, options?)`, `sendMessage(message, options?)`, `on(event, handler)`.
-The argument additionally carries an internals namespace under `.pi`; irrelevant to st2.
-
-**Lifecycle events use pi's names, minus `agent_settled`.** Observed firing in one interactive
-turn: `session_start`, `agent_start`, `turn_start`, `message_start`, `message_end`,
-`turn_end`, `agent_end`, `session_shutdown`. `agent_settled` never fired and the string does
-not occur anywhere in the binary (1M-string scan). Handler registration for unknown names does
-not throw, so absence is silent.
-
-**The idle edge exists but is sampled, not evented.** In the interactive run,
-`ctx.isIdle()` was still `false` at `agent_end` and flipped `true` by the +251 ms sample. Rule:
-idle is `agent_end` followed by bounded polling until `isIdle()` is true; a queued follow-up
-turn keeps it false, so no spurious idle blip.
-
-**Idle delivery lands and drives a full turn.** Interactive run with tools enabled: extension
-polled a trigger file every 200 ms, called `pi.sendUserMessage(body)` while idle; the model
-received it, acted (wrote the requested file correctly), turn events fired, and the session
-settled back to idle. End-to-end native delivery confirmed without touching any screen.
-
-**Mid-turn steer accepted in print mode.** From inside `message_start`, `sendUserMessage(text,
-{ deliverAs: "steer" })` returned without error. Not yet visually verified in the interactive
-TUI (DQ-OMP-4).
-
-**Approval events exist and fire — omp is richer than pi here.** Under
-`--approval-mode always-ask`, a bash call produced:
-
-```
-tool_approval_requested { type, sessionId, toolName: "bash", toolCallId, approvalMode }
-tool_approval_resolved  { ..., approved: true }
-```
-
-The requested event carries a correlating `toolCallId`, giving the blocked exit edge pi lacks
-entirely. Without forced approval mode the events did not fire (the same command auto-ran).
-
-**Context object differences.** Event-handler `ctx` exposes `{ ui }` only — no abort `signal`
-(pi's channel uses `ctx.signal?.addEventListener` optionally, so the fork loses nothing).
-`ctx.ui.notify` is present.
-
-**Unresolved by this capture:** the update-check banner appeared in every interactive boot;
-whether `PI_OFFLINE`/`PI_SKIP_VERSION_CHECK` suppress it was not established in print mode
-(the banner never renders there) — DQ-OMP-5.
-
-## Conclusion
-
-The pi-driver mechanism ports to omp with one structural divergence: the idle edge must be
-derived by polling `ctx.isIdle()` after `agent_end` instead of listening for `agent_settled`.
-A native omp driver is viable at full parity — presence lease, observed state including the
-blocked-on-human axis pi cannot express, and native delivery. The measured divergences
-justify forking the channel asset rather than parameterizing pi's.
-
-## VRS Impact
-
-Grounds OMP-R02 (observed axes, from the approval-event payloads and idle sampling),
-OMP-R03 (idle edge rule), OMP-R04 (fork rationale), OMP-T01/T02 (deny path and ask axis
-unmeasured), and DQ-OMP-3..5 (steer visual, modal interaction, banner suppression).
-
-## Driver e2e run
-
-The same day, the implemented driver ran end-to-end on dev3: a scratch catalog declared
-`agent "omp-smoke"` with a `driver omp` block; `st2 hooks install` published the set including
-`omp-channel.ts`; `st2 driver omp-session` launched the TUI under the wrapper. Verified: the
-presence record read `available`; the harness-state record seeded `idle` under
-`harness: "omp"`, fenced by the wrapper's session token (`seq 1`, pty session bound); a
-`st2 message send` landed in the live TUI via the channel together with the
-`st2-session-start` restored-context block; observed state cycled active → idle
-(transitions 3→5) around the delivery. The model's reply itself failed with a provider-side
-429 weekly usage limit — outside st2's surface.
-
-## Fleet e2e run (dotfiles integration)
-
-The dotfiles side activated the driver on dev3 through the standing
-`dev3.omp-scratch` seat (launched by the production supervisor via
-`st2 driver omp-session`, st2 repinned to this branch). Verified live: the
-seat materialized into the catalog, reached presence `available`, published
-the harness-state record (`harness: "omp"`, seeded idle, fenced by the
-wrapper's session token), and a `st2 message send` from `dev3.cos` landed in
-its live TUI through the channel with observed state cycling active → idle
-(transitions around the delivery). The model's reply was blocked by a
-provider-side 429 weekly usage limit on the opencode-go workspace - the same
-external quota exhaustion visible across the fleet that day; the
-model-acts-on-delivery step is covered by the manual runs above.
-
-Integration findings recorded on the way: Nix standing seats launch through
-the `axe agent launch` carrier, which spawns the raw harness binary - so a
-driver-backed seat that wants the wrapper's machinery must declare the
-`st2 driver <h>-session` argv directly rather than ride the axe carrier; and
-axe's managed path requires a profile account binding plus a fixed-account
-credential availability probe, which omp satisfies with its install-identity
-file since its native OAuth exposes no projectable credential.
-
-## Correction (2026-08-29): the `ctx` enumeration above is incomplete
-
-The "Context object differences" finding states that the event-handler `ctx`
-exposes `{ ui }` only. That is a **probe artifact of this capture, not a fact
-about 18.0.3**. A re-probe on 2026-08-29 walked
-`Object.getOwnPropertyNames` over the handler `ctx` at every lifecycle event
-against both binaries — `18.0.3` (`/nix/store/zv3xvic38a2gcdpxk3wd5fsk6plsgvbn-omp-18.0.3/bin/omp`)
-and `18.0.9` — and got the **identical** key set from both:
-
-```text
-abort, clearTimer, compact, cwd, getAsyncJobSnapshot, getContextUsage, getSystemPrompt,
-hasPendingMessages, hasUI, invokeTool, isIdle, isProjectTrusted, localProtocolOptions, memory,
-mode, model, modelRegistry, models, sessionManager, setInterval, setTimeout, shutdown, ui
-```
-
-`ctx.getContextUsage()` works on 18.0.3 as it does on 18.0.9 — measured
-`session_start {"tokens":2078,"contextWindow":4000,"percent":51.95}` against a
-fake provider — and the string `getContextUsage` occurs 35 times in each of the
-two binaries. So the call was available the whole time; no omp release added it.
-
-What this capture got right stands: `signal` is genuinely absent from the `ctx`
-of both versions, and `agent_settled` is absent from both (0 occurrences by
-binary scan), so OMP-R03's polling rule remains load-bearing.
-
-The correction matters for OMP-R05's admission checklist, which would otherwise
-inherit a false "omp gained a context API between 18.0.3 and 18.0.9" story from
-this file. The same incomplete enumeration is repeated in
-[`2026-08-28-omp-18-0-9-admission.md`](./2026-08-28-omp-18-0-9-admission.md)
-(Result item 2) and in [`spec.md`](../spec.md) (Channel section, "`ctx = {ui}`");
-both are accurate about `signal` and wrong about the rest of the key set.
-
-Full evidence:

-# omp 18.0.9 admission checks
-
-## Question
-
-The omp version gate admits exactly `18.0.3`. The runtime profile now pins
-`18.0.9`, so every seat declaring omp validates clean and then dies at launch.
-Per OMP-R05, may `18.0.9` be admitted — that is, do the five delivery-critical
-checks still hold on it, or has the versioned surface moved?
-
-Date: 2026-08-28. Binary under test: **omp/18.0.9**, resolved store path
-`/nix/store/7ynhrg7bzgal1wki6492j3w5x1dgs8p7-omp-18.0.9/bin/omp`
-(`readlink -f` on the `binPath` the coding-agent-runtime profile pins for
-`accountId omp/omp-default`; `--version` prints `omp/18.0.9`). Linux x86_64,
-dev3. Compared against the `18.0.3` baseline in
-[`2026-08-25-omp-harness-integration.md`](./2026-08-25-omp-harness-integration.md).
-
-Two facts about the environment are worth stating because they mislead:
-`omp` on a dev3 interactive `PATH` still resolves to
-`/nix/store/zv3xvic38a2gcdpxk3wd5fsk6plsgvbn-omp-18.0.3/bin/omp`, so a bare
-`omp` measures the *old* binary; every command below names the 18.0.9 path
-explicitly. And `18.0.3 → 18.0.9` is a **patch** bump, which matters because the
-gate matches exact versions, not a range.
-
-## Method
-
-Four throwaway TypeScript extensions loaded with `-e`, each writing observations
-to a JSON file, mirroring the 18.0.3 method. Print-mode runs used
-`--no-session --no-tools --no-lsp --no-skills --no-rules`; interactive runs held
-the TUI in a `pty` session, and the approval run forced
-`--approval-mode always-ask`. The delivery loop was then repeated a second time
-through the *shipped* `omp-channel.ts` under `st2 driver omp-session`, which
-exercises the real code path rather than a probe's imitation of it.
-
-One environmental trap: omp blocks indefinitely in startup phase
-`readPipedInput` when stdin is a non-TTY pipe. Every non-interactive probe run
-needs `< /dev/null`.
-
-## Result
-
-**1. Extension-load probe — unchanged.** The default-export pi-style extension
-loads, and the first argument still carries all three calls the st2 channel
-uses: `sendUserMessage`, `sendMessage`, `on` (each `typeof === "function"`). The
-`.pi` internals namespace is still present. OMP-A01 holds on this build.
-
-**2. Lifecycle event inventory — unchanged, and `agent_settled` is still
-absent.** One print-mode turn fired, in order: `session_start`, `agent_start`,
-`turn_start`, `message_start`, `message_end`, `message_start`, `message_end`,
-`turn_end`, `agent_end`, `session_shutdown` — the same vocabulary and order as
-18.0.3. Registering a handler for `agent_settled` did not throw and it never
-fired; the string has **0 occurrences** in the 18.0.9 binary by both
-`strings -a -n 4` and a raw byte `grep -a`. `tool_approval_requested` and
-`tool_approval_resolved` are present in the binary (3 occurrences each). Handler
-`ctx` still exposes `{ ui }` only — no abort `signal`. So OMP-R03's polling rule
-is still required, not vestigial.
-
-**3. Idle-edge sampling — rule holds, timing moved.** `ctx.isIdle()` was
-`false` at `agent_end` in both modes and flipped `true` at the first poll
-25 ms later (interactive; 26 ms in print mode, 25 ms sample interval). 18.0.3
-measured +251 ms interactive. The settle is *faster* on 18.0.9, but the rule is
-unchanged and still load-bearing: idle must not be emitted at `agent_end`
-itself, because it is still measurably false there.
-
-**4. Approval-event capture — unchanged, including the correlating id.** Under
-`--approval-mode always-ask`, a bash call produced both events with the same
-payload shape as 18.0.3:
-
-```
-tool_approval_requested { type, sessionId, toolName: "bash",
-                          toolCallId: "call_3jur…|fc_0056…", approvalMode: "always-ask" }
-tool_approval_resolved  { type, sessionId, toolName: "bash",
-                          toolCallId: "call_3jur…|fc_0056…", approved: true }
-```
-
-The `toolCallId` matches across the pair, so the blocked-on-human exit edge
-(OMP-R02) still correlates. The deny path remains unmeasured, as at 18.0.3
-(OMP-T01, DQ-OMP-1).
-
-**5. Live delivery loop — lands and drives a full turn.** Probe: an extension
-polled a trigger file every 200 ms and called `sendUserMessage(body)` while
-idle. The model received it, acted correctly (wrote the requested file with the
-requested content), and the turn events fired around it.
-
-**Driver e2e through the shipped channel.** The same delivery was then repeated
-end to end on the real path, which is the check that actually stands behind the
-gate. A scratch catalog declared `omp909-gate-demo`; `st2 driver omp-session`
-launched the 18.0.9 TUI under the wrapper. Verified: presence reached
-`available`; the harness-state record published as
-
-```json
-{"schema":"st2.harness-state.v1","harness":"omp","state":"idle","blockedOn":"none",
- "ptySession":"omp909-demo-run","seq":1,"transitions":1}
-```
-
-seeded idle and fenced by the wrapper's session token; a real
-`st2 message send` landed in the live TUI through `omp-channel.ts`; the model
-acted on it and wrote the requested artifact; and observed state cycled and
-returned to idle (`transitions` 1 → 3). Unlike the 18.0.3 capture, whose model
-reply was blocked by a provider-side 429, this run completed the
-model-acts-on-delivery step live.
-
-**Gate demonstration.** With the gate unchanged, the launch fails:
-
-```
-Error: omp 18.0.9 is unverified (admitted: 18.0.3); repeat the
-docs/vrs/06-omp-driver admission checks before extending the gate
-```
-
-With `18.0.9` added to `SUPPORTED_OMP_VERSIONS`, the identical command launches
-and reaches the state above. The two runs differ only in that constant.
-
-**Noted, not blocking:** the interactive TUI advertised `18.0.10` as already
-available. omp's release cadence is faster than this admission process, which is
-the standing cost of an exact-version gate and is the intended tradeoff, not a
-defect. The update banner still appears in interactive boots (DQ-OMP-5 remains
-open, unchanged from 18.0.3).
-
-## Conclusion
-
-All five OMP-R05 checks pass on omp 18.0.9 against measured output, with no
-change to any delivery-critical behavior: the extension API, the event
-vocabulary, the missing `agent_settled`, the sampled idle edge, and the approval
-pair with its correlating `toolCallId` are all as measured at 18.0.3. The only
-observed difference is that the idle edge settles faster (25 ms vs 251 ms),
-which does not change the rule. Admitting `18.0.9` is justified.
-
-Admission stays **per exact version**. `18.0.9` is added to the admitted set
-alongside `18.0.3`; the range reading is not adopted, because an unmeasured
-patch between two admitted versions — `18.0.4`, say — has no evidence behind it
-and stays refused.
-
-## VRS Impact
-
-Extends the admitted set in `src/omp_session.rs` from `["18.0.3"]` to
-`["18.0.3", "18.0.9"]` under OMP-R05, together with this capture. Re-confirms
-OMP-A01 (extension surface), OMP-R02 (approval payloads and the correlating id)
-and OMP-R03 (idle edge derived by polling) on a second version. Corrects
-spec.md's "verified range (18.x)" wording, which described the gate as a range
-while the implementation has always matched exact versions. Leaves OMP-T01/T02
-and DQ-OMP-1..5 open and unchanged.

-# omp 18.1.2 admission checks
-
-## Question
-
-The omp launch gate admits the `18.0` minor series. The coding-agent-runtime
-profile now pins `18.1.2`; per OMP-R05, may the `18.1` series be admitted, or
-did one of the delivery-critical surfaces move?
-
-Date: 2026-09-02. Profile under test:
-`/nix/store/w5i48iwnmy92izxkg4473im45bk1akbw-coding-agent-runtime-profile.json`.
-Selecting `accountId == "omp/omp-default"` resolves `execution.binPath` to
-`/nix/store/j6811vbwii56ajl18svasjj8gijaj80r-omp-18.1.2/bin/omp`.
-`readlink -f` returns that same path and `--version` prints `omp/18.1.2`.
-Linux x86_64. Every probe below names that store binary explicitly.
-
-## Method
-
-The five OMP-R05 checks from
-[`2026-08-28-omp-18-0-9-admission.md`](./2026-08-28-omp-18-0-9-admission.md)
-were repeated with throwaway TypeScript extensions. Print mode used
-`-p --no-session --no-tools --no-lsp --no-skills --no-rules --no-extensions`
-and redirected stdin from `/dev/null`; interactive checks ran in named PTYs.
-The approval check forced `--approval-mode always-ask`. All probe output,
-session state, the hook root, catalog, workspace, and PTY registry lived below
-one newly-created `/tmp/st2-omp1812-admission.*` root.
-
-The delivery check did not imitate the channel. The branch's built `st2` binary
-installed its immutable hook set into the disposable hook root and launched the
-candidate through `st2 driver omp-session`; the injected shipped
-`omp-channel.ts` spawned that same `st2` as `driver omp-channel`. The scratch
-catalog validated with zero errors and zero warnings before launch.
-
-## Result
-
-**1. Extension load — pass.** At extension initialization the first argument
-reported:
-
-```json
-{"sendUserMessage":"function","sendMessage":"function","on":"function","piNamespace":true}
-```
-
-The three calls used by the shipped channel and the `.pi` internals namespace
-therefore remain present.
-
-**2. Lifecycle inventory and missing `agent_settled` — pass.** A print-mode
-turn fired, in order:
-
-```text
-session_start, agent_start, turn_start,
-message_start, message_end, message_start, message_end,
-turn_end, agent_end, session_shutdown
-```
-
-The interactive turn fired the same order through `agent_end` (the TUI was
-then deliberately kept alive). Registering `agent_settled` did not throw and no
-such event fired in either run. A raw byte count over the candidate binary found
-`agent_settled` **0** times. The same count found
-`tool_approval_requested` **3** times and `tool_approval_resolved` **3** times.
-OMP-R03's sampled settle remains necessary.
-
-**3. Idle edge — pass.** `ctx.isIdle()` was `false` at `agent_end` in both
-modes. With a 25 ms sampler, the interactive run's first sample at **+26 ms**
-was `true`. In print mode the first runnable sample was `true` at **+186 ms**
-(after `session_shutdown`, while the scheduled sampler was still live). The
-load-bearing rule is unchanged: `agent_end` itself is not an idle proof; the
-channel must wait for the first positive bounded poll.
-
-**4. Approval correlation — pass.** An interactive bash tool call under
-`--approval-mode always-ask` emitted this pair and the approved command wrote
-`APPROVAL_OK`:
-
-```text
-tool_approval_requested
-  sessionId: 01a06337-8ca5-75ef-8aed-6d65ea68ad77
-  toolName: bash
-  toolCallId: call_RFtkTfped0aDxOJf6lTR4CRe|fc_0b1ce953da5da810016a986026e18887d283e902092fca9482
-  approvalMode: always-ask
-
-tool_approval_resolved
-  sessionId: 01a06337-8ca5-75ef-8aed-6d65ea68ad77
-  toolName: bash
-  toolCallId: call_RFtkTfped0aDxOJf6lTR4CRe|fc_0b1ce953da5da810016a986026e18887d283e902092fca9482
-  approved: true
-```
-
-Both `sessionId` and the complete `toolCallId` match across the pair, preserving
-the OMP-R02 blocked-on-human correlation edge.
-
-**5. Shipped-driver live delivery — pass.** The built branch binary installed
-hook set
-`sha256-2d4f8a83808b43fd1291a3d21567185fdf1a75a7357098970fba2fac6acc329e`
-and launched `lab.omp1812` through `st2 driver omp-session` with PTY runtime
-`omp1812-demo-run`. In the clean measured incarnation, the wrapper and channel
-published:
-
-```json
-{"schema":"st2.harness-state.v1","agent":"lab.omp1812","harness":"omp",
- "state":"idle","blockedOn":"none","inputBuffer":"unknown","ask":"none",
- "ptySession":"omp1812-demo-run","incarnation":"60587-1788371709709-0",
- "seq":2,"transitions":9}
-```
-
-Presence was `available`. A real
-`st2 message send lab.omp1812 --as lab.omp1812` created
-`1788371738141-gaf07f.md`. The shipped channel delivered its body into the idle
-TUI without screen injection: harness state moved to `active`, transitions
-**10**; the model ran the requested bash command and produced the exact artifact
-content `CLEAN_SHIPPED_DRIVER_DELIVERY_OK`; it replied
-`CLEAN_DRIVER_DELIVERY_DONE`; and state returned to `idle`, transitions **11**,
-under the same incarnation and sequence. This covers the delivery path that the
-minor gate protects.
-
-## Focused verification
-
-```text
-$ nix develop -c cargo test --lib omp_session::tests
-running 14 tests
-...
-test result: ok. 14 passed; 0 failed; 0 ignored; 0 measured; 657 filtered out
-
-$ nix develop -c cargo build --bin st2
-Finished `dev` profile [unoptimized + debuginfo] target(s) in 38.17s
-```
-
-The build emitted pre-existing warnings outside this change; neither command
-reported an error. The disposable driver PTY was killed and removed, then the
-entire probe root (catalog, hook set, PTY registry, workspace, extensions,
-logs, and artifacts) was deleted.
-
-## Conclusion
-
-All five delivery-critical checks pass on omp 18.1.2. The extension API,
-lifecycle vocabulary, still-missing `agent_settled`, sampled idle edge,
-approval correlation, and shipped driver delivery loop remain valid. Admitting
-the `18.1` minor series alongside `18.0` is justified under decision 0007-omp-is-a-fifth-native-driver-with-its-own-channel-and-a-hard-version-gate and
-OMP-R05.
-
-The gate remains per minor. This capture does not assert that harness-context
-`tokens` arithmetic was remeasured on 18.1.2; the exact-build fixture for that
-separate HC-R13/HC-T03 question remains unchanged.
-
-## Residual risk
-
-- The approval deny path remains unmeasured, as in the 18.0 captures (OMP-T01,
-  DQ-OMP-1).
-- This is one Linux x86_64 capture using the configured `openai-codex`
-  GPT-5.6-Sol model and the approval success path; it is not a provider matrix.
-- Minor-series admission intentionally lets later `18.1.x` patches launch
-  without another capture. A new minor remains refused.
-- The interactive TUI advertised `18.1.4` during the probe. Update-banner
-  suppression remains the existing DQ-OMP-5 concern and did not affect delivery.
-
-## VRS Impact
-
-Extends `SUPPORTED_OMP_MINORS` in `src/omp_session.rs` from `[(18, 0)]` to
-`[(18, 0), (18, 1)]`, pins the three admission capture builds in the focused
-gate test, and keeps neighbouring minors, majors, ambiguous banners, and
-pre-releases fail-closed. OMP-R02, OMP-R03, OMP-R05, and OMP-A01 remain
-satisfied; no open question is closed by this capture.

-# omp provider-credential rejection: which field names it
-
-## Question
-
-st2 classifies a rejected provider credential for OpenCode, Claude, and Codex
-(#452). omp is the fleet's default managed harness and had no auth-class signal
-at all: a seat whose credential was refused looked exactly like a quiet one.
-
-Does omp expose a STRUCTURED signal that separates a refused credential from an
-exhausted allowance, or only the prose the channel already forwards? The live
-counter-example that motivates the question is a dev3 seat wedged with
-`"reason":"403 You have run out of credits…"` and 120 harness-state transitions:
-a 403 that no re-login fixes. Any classifier that keys on `401|403` — in the
-status code or in the prose — reports that seat as a rejected credential.
-
-Date: 2026-09-05. Binary under test: `readlink -f $(which omp)` →
-`/nix/store/7q6b5pb5pxcjhpmbqy0lv79vb116vbhx-omp-18.1.7/bin/omp`,
-`--version` prints `omp/18.1.7`. Linux x86_64.
-
-## Method
-
-Two parts.
-
-**1. Source read.** The candidate binary is a Bun single-file executable that
-embeds its own sources; `strings -n 6` recovers them. The relevant module is
-`packages/ai/src/error/`:
-
-- `qe` is a flag bitfield: `Class: 4096`, `AccountPolicy: 16384`,
-  `ContentBlocked: 32768`, `UsageLimit: 524288`, `Transient: 131072`,
-  `AuthFailed: 16777216`, `PayloadRejected: 2147483648`, and others.
-- `jr(...flags)` ORs the flags AND SETS `qe.Class`, so `Class` is what
-  distinguishes a CLASSIFICATION from a bare HTTP status: when no flag fires,
-  the same field carries the raw status (or `0`).
-- An assistant message whose turn failed carries three fields, assigned
-  together at the provider-stream boundary: `i.stopReason = d.stopReason;
-  i.errorStatus = d.status; i.errorId = d.id; i.errorMessage = …`. `errorId`
-  is that bitfield.
-- omp's OWN credential-invalidating rule, in its `agent_end` maintenance
-  routing, is `Kt(ld(f), qe.AuthFailed) && !Kt(_, qe.UsageLimit) && !O` where
-  `O` is a `CONCURRENT_LIMIT` message — i.e. `AuthFailed` minus capacity. It
-  reaches for the credential store only under that conjunction.
-- `AuthFailed` is set from the prose regex
-  `/\b(?:401|403|unauthorized|forbidden|authentication|…)\b/i` as well as from
-  a typed status, which is exactly why it needs the negative flags: the words
-  co-occur.
-- `stripInternalDetailsFields` removes only `__queueChipText`, and `agent_end`
-  emits `messages: e` unsanitized, so an extension sees all three fields.
-
-**2. Measurement.** A Bun server on `127.0.0.1` impersonating the Anthropic
-Messages API, selected through `ANTHROPIC_BASE_URL`, returns one chosen status
-and body per case. omp ran in print mode
-(`-p --no-session --no-tools --no-lsp --no-skills --no-rules --no-extensions`)
-against `anthropic/claude-sonnet-4-5` with `ANTHROPIC_API_KEY=sk-ant-lab-bogus`
-and one throwaway extension that appended `role`, `stopReason`, `errorMessage`,
-`errorStatus`, `errorId` and the message's own `error*` keys for every
-`agent_end` message. All state (`HOME`, `OMP_PROFILE=authlab`, workspace,
-output) lived under one `/tmp/st2-omp-auth-lab` root.
-
-## Result
-
-Every failing turn carried all three fields as own enumerable properties
-(`ownKeys` reported `["errorStatus","errorId","errorMessage"]`). The successful
-turn carried `errorId: 0` and no `errorStatus`/`errorMessage` at all.
-
-| case | HTTP | `errorStatus` | `errorId` | hex | flags | `willContinue` |
-| --- | --- | --- | --- | --- | --- | --- |
-| `invalid x-api-key` | 401 | 401 | 16781312 | `0x1001000` | AuthFailed \| Class | — |
-| `OAuth token has expired: invalid_grant` | 401 | 401 | 16781312 | `0x1001000` | AuthFailed \| Class | — |
-| `API key does not have permission` | 403 | 403 | 16781312 | `0x1001000` | AuthFailed \| Class | — |
-| **`You have run out of credits`** | 403 | 403 | 17305600 | `0x1081000` | AuthFailed \| **UsageLimit** \| Class | — |
-| `cyber_policy: trusted access…` | 403 | 403 | 16830464 | `0x100d000` | AuthFailed \| **AccountPolicy** \| ContentBlocked \| Class | — |
-| `CONCURRENT_LIMIT: too many concurrent requests` | 403 | 403 | 16912384 | `0x1021000` | AuthFailed \| **Transient** \| Class | `true` |
-| `Payment required: insufficient balance` | 402 | 402 | 528384 | `0x81000` | UsageLimit \| Class | — |
-| `rate limit` | 429 | 429 | 135168 | `0x21000` | Transient \| Class | `true` |
-| ordinary turn (streamed 200) | 200 | *absent* | 0 | `0x0` | none — `stopReason: "stop"` | — |
-
-Four facts fall out of that table.
-
-1. **The status code is not the signal.** Three of the four 403s are not
-   credential rejections, and the one that is shares its status with all of
-   them. `401|403` — in the code or in the prose — misclassifies the exact live
-   seat that motivated this work.
-2. **`errorId` is the signal**, and the discriminator is `AuthFailed` minus
-   `UsageLimit`, `AccountPolicy`, and `Transient`. Each negative flag is
-   measured, not assumed: credits set `UsageLimit`, a policy refusal sets
-   `AccountPolicy`, and `CONCURRENT_LIMIT` — the case omp's own rule spells out
-   in prose — sets `Transient`.
-3. **`Class` must be checked.** Without a flag, the same field carries the raw
-   status, so the bit test has to know it is reading a classification.
-4. **A retried error never ends a turn.** Both `Transient` cases arrived with
-   `willContinue: true` and repeated; the shipped extension already returns
-   early on that, so no credential edge is ever claimed mid-turn. The ordinary
-   end is unambiguous in the other direction: `stopReason: "stop"` with no
-   error fields is the recovery edge.
-
-## Conclusion
-
-The omp extension forwards omp's own words — the bounded prose plus `errorId` —
-on a `type: "turn"` frame at every turn that actually ended, and st2 owns the
-verdict, as it does for every other producer: `Source::TurnResult` +
-`Reason::ProviderAuthRejected` under `Driver::Omp`, with reason `providerAuth`
-on the observed-state record. `errorStatus` is deliberately NOT on the wire: it
-classifies nothing this record needs, and it is already inside the prose omp
-puts in `errorMessage` (`"403 {…}"`).
-
-## VRS Impact
-
-The result grounds omp provider-auth classification in the `errorId` bitfield,
-including the negative capacity and policy flags, rather than HTTP status or
-error prose.

-# omp 18.3.0 admission checks
-
-## Question
-
-The omp launch gate admits the `18.0` and `18.1` minor series. The managed
-runtime now ships `18.3.0`; per OMP-R05, may the `18.3` series be admitted, or
-did one of the delivery-critical surfaces move? The intervening `18.2` minor is
-not measured by this capture and must remain refused.
-
-Date: 2026-09-24. Binary under test:
-`/nix/store/b2y6c25kq59pnwrbx3l5mbp1naz4wzbg-omp-18.3.0/bin/omp`.
-`--version` printed `omp/18.3.0`. Linux x86_64, dev3. Every probe below named
-that store binary explicitly.
-
-## Method
-
-The five OMP-R05 checks from
-[`2026-08-28-omp-18-0-9-admission.md`](./2026-08-28-omp-18-0-9-admission.md)
-were repeated with throwaway TypeScript extensions. Print mode used
-`-p --no-session --no-tools --no-lsp --no-skills --no-rules --no-extensions`,
-loaded the explicit probe with `-e`, and redirected stdin from `/dev/null`.
-Interactive checks ran in isolated named PTYs. The approval check forced
-`--approval-mode always-ask`. All probe output, session state, hook root,
-catalog, workspace, and PTY registries lived below one newly-created
-`/tmp/st2-omp1830-admission.*` root.
-
-The delivery check used the shipped path rather than imitating the channel. The
-branch's built `st2` binary installed its immutable hook set into the disposable
-hook root and launched the candidate through `st2 driver omp-session`; the
-injected shipped `omp-channel.ts` spawned that same `st2` as `driver
-omp-channel`. The scratch catalog validated with zero errors and zero warnings.
-
-## Result
-
-**1. Extension load — pass.** At extension initialization the first argument
-reported:
-
-```json
-{"sendUserMessage":"function","sendMessage":"function","on":"function","piNamespace":true}
-```
-
-The three calls used by the shipped channel and the `.pi` internals namespace
-remain present. This is unchanged from 18.0.9 and 18.1.2.
-
-**2. Lifecycle inventory and missing `agent_settled` — pass.** A print-mode
-turn fired, in order:
-
-```text
-session_start, agent_start, turn_start,
-message_start, message_end, message_start, message_end,
-turn_end, agent_end, session_shutdown
-```
-
-The interactive turn fired the same order; `session_shutdown` arrived when the
-probe PTY was deliberately stopped. Registering `agent_settled` did not throw
-and no such event fired. A raw byte count over the candidate binary found
-`agent_settled` **0** times. It found `tool_approval_requested` **5** times and
-`tool_approval_resolved` **5** times; the previous 18.0.9 and 18.1.2 captures
-found three copies of each approval-event string, but the observed event names
-and payload behavior below did not change. OMP-R03's sampled settle remains
-necessary.
-
-**3. Idle edge — pass.** `ctx.isIdle()` was `false` at `agent_end` in both
-modes. With a 25 ms sampler, the interactive run's first sample at **+26 ms**
-was `true`; the print-mode run's first sample at **+34 ms** was `true`.
-Interactive timing is effectively unchanged from 18.0.9 (+25 ms) and 18.1.2
-(+26 ms). Print timing is close to 18.0.9 (+26 ms) and faster than the +186 ms
-18.1.2 sample. The load-bearing rule is unchanged: `agent_end` itself is not an
-idle proof; the channel must wait for the first positive bounded poll.
-
-**4. Approval correlation — pass.** An interactive bash tool call under
-`--approval-mode always-ask` emitted this pair and the approved command wrote
-`APPROVAL_OK`:
-
-```text
-tool_approval_requested
-  sessionId: 01a0d327-f97b-73f0-b753-79deec0d93d7
-  toolName: bash
-  toolCallId: call_3qGiZrIwTc9U7mpZdbpnI5t9|fc_0309d0d61cdae49e016ab50833382087d28df84c5a09c533fb
-  approvalMode: always-ask
-
-tool_approval_resolved
-  sessionId: 01a0d327-f97b-73f0-b753-79deec0d93d7
-  toolName: bash
-  toolCallId: call_3qGiZrIwTc9U7mpZdbpnI5t9|fc_0309d0d61cdae49e016ab50833382087d28df84c5a09c533fb
-  approved: true
-```
-
-Both `sessionId` and the complete `toolCallId` match across the pair, preserving
-the OMP-R02 blocked-on-human correlation edge. This payload shape is unchanged
-from 18.0.9 and 18.1.2.
-
-**5. Shipped-driver live delivery — pass.** Before the gate edit, the built
-wrapper refused the candidate without claiming the seat:
-
-```text
-Error: omp 18.3.0 is unverified (admitted minors: 18.0.x, 18.1.x); repeat the
-docs/vrs/06-omp-driver admission checks before extending the gate
-```
-
-With only `18.3` added to `SUPPORTED_OMP_MINORS`, the same binary installed hook
-set
-`sha256-83f5c9558982ce85c094e2d769ef4eaebcf0cab7d8670702c2a9663806cfcc5e`
-and launched `lab.omp1830` through `st2 driver omp-session` with PTY runtime
-`omp1830-demo-run`. Presence reached `available`, and the wrapper and shipped
-channel published:
-
-```json
-{"schema":"st2.harness-state.v1","agent":"lab.omp1830","harness":"omp",
- "state":"idle","blockedOn":"none","inputBuffer":"unknown","ask":"none",
- "ptySession":"omp1830-demo-run","incarnation":"616732-1790249631546-0",
- "seq":1,"transitions":1}
-```
-
-A real `st2 message send lab.omp1830 --as lab.omp1830` created
-`1790249647054-vgc047.md`. The shipped channel delivered its body into the idle
-TUI without screen injection: harness state moved to `active`, transitions
-**2**; the model ran the requested bash command and produced the exact artifact
-content `DRIVER_DELIVERY_OK`; it replied `DRIVER_DELIVERY_DONE`; and state
-returned to `idle`, transitions **3**, under the same incarnation and sequence.
-This is the same complete delivery behavior measured on 18.0.9 and 18.1.2.
-
-## Focused verification
-
-```text
-$ nix develop -c cargo test --lib omp_session::tests
-running 19 tests
-...
-test result: ok. 19 passed; 0 failed; 0 ignored; 0 measured; 813 filtered out
-
-$ nix develop -c cargo build --bin st2
-Finished `dev` profile [unoptimized + debuginfo] target(s) in 50.83s
-```
-
-Both commands emitted pre-existing warnings outside this change; neither
-reported an error. The lifecycle, approval, and shipped-driver PTYs were stopped
-after their captures.
-
-## Conclusion
-
-All five delivery-critical checks pass on omp 18.3.0. The extension API,
-lifecycle vocabulary, still-missing `agent_settled`, sampled idle edge,
-approval correlation, and shipped driver delivery loop remain valid. Admitting
-the `18.3` minor series alongside `18.0` and `18.1` is justified under decision
-0007-omp-is-a-fifth-native-driver-with-its-own-channel-and-a-hard-version-gate
-and OMP-R05.
-
-The gate remains per minor. This capture does not admit or make any claim about
-`18.2`, and it does not assert that harness-context `tokens` arithmetic was
-remeasured on 18.3.0; the exact-build fixture for that separate HC-R13/HC-T03
-question remains unchanged.
-
-## Residual risk
-
-- The approval deny path remains unmeasured, as in the earlier captures
-  (OMP-T01, DQ-OMP-1).
-- This is one Linux x86_64 capture using the configured `openai-codex`

-- Minor-series admission intentionally lets later `18.3.x` patches launch
-  without another capture. A new minor remains refused.
-
-## VRS Impact
-
-Extends `SUPPORTED_OMP_MINORS` in `src/omp_session.rs` from
-`[(18, 0), (18, 1)]` to `[(18, 0), (18, 1), (18, 3)]`, adds `18.3.0` to the
-literal admission-build test, and keeps the unmeasured `18.2` minor,
-neighbouring minors, majors, ambiguous banners, and pre-releases fail-closed.
-OMP-R02, OMP-R03, OMP-R05, and OMP-A01 remain satisfied; no open question is
-closed by this capture.

-# omp 18.4.2 admission checks
-
-## Question
-
-The omp launch gate admits `18.0`, `18.1`, and `18.3`. May the managed
-`18.4.2` binary admit the `18.4` series under OMP-R05? `18.2` remains
-unmeasured and refused.
-
-Date: 2026-09-29. Binary:
-`/nix/store/cxylsx4nnzmdwh8kb2i5nfwv6lys4p8r-omp-18.4.2/bin/omp`;
-`--version` printed `omp/18.4.2`. Linux x86_64, dev3.
-
-## Method
-
-Repeated the five checks from
-[`2026-09-24-omp-18-3-0-admission.md`](./2026-09-24-omp-18-3-0-admission.md)
-with a disposable TypeScript extension. Print invocation explicitly used
-`-p --no-session --no-tools --no-lsp --no-skills --no-rules --no-extensions
--e /tmp/ompr05-1000/probe.ts 'Reply with exactly PRINT_OK' </dev/null`.
-Interactive lifecycle and approval checks used separate named PTYs in the
-scratch `PTY_ROOT=/tmp/ompr05-1000/pty`. Approval used
-`--approval-mode always-ask`; Johannes personally selected Approve in the
-isolated PTY. The same extension logged event name, timestamp, `ctx.isIdle()`,
-and approval correlation fields to separate JSONL files; its `agent_end`
-listener started a bounded 25 ms poll (at most 80 samples).
-
-The real login `HOME` retained the existing provider login without copying
-or modifying it. XDG configuration/state/runtime, `PTY_ROOT`, `ST_HOOKS`,
-catalog, workspace, daemon socket and outputs were isolated below
-`tmp/st3-adoption/omp-r05/` (short socket alias `/tmp/ompr05-1000`).
-The daemon was the integration branch
-`schickling-assistant/dotfiles-integration` at `e8e68762` (including the
-sandbox fleet-test fix #688), built with `CARGO_BUILD_JOBS=8`. Its Nix build's
-unrelated example test failed because `/bin/rm` is absent from the Nix build
-sandbox; the identical source was built with `doCheck=false` for this live
-probe. The integration branch's `st2` was built and used for the shipped-driver
-check, temporarily adding only `(18, 4)` after first measuring refusal.
-The isolated `st3 up` daemon used explicit scratch state, socket, PTY root,
-client gateway and PTY binary; a private user/mount namespace bound a scratch
-`/usr/bin` with `env` and `printf` for its login-shell environment probe.
-No shared broker or live PTY registry was changed.
-
-## Result
-
-**1. Extension load — pass.** Extension initialization recorded:
-
-```json
-{"sendUserMessage":"function","sendMessage":"function","on":"function","piNamespace":true}
-```
-
-**2. Lifecycle inventory — pass.** The print-mode turn recorded, in order:
-
-```text
-session_start, agent_start, turn_start,
-message_start, message_end, message_start, message_end,
-turn_end, agent_end, session_shutdown
-```
-
-The interactive turn recorded the same sequence; its `session_shutdown` fired
-when its PTY was deliberately stopped. Registering `agent_settled` succeeded,
-but neither mode emitted that event. No changed event name was observed.
-The approval event names remained `tool_approval_requested` and
-`tool_approval_resolved`.
-
-**3. Idle edge — pass.** At `agent_end`, `ctx.isIdle()` was `false` in
-both modes. The interactive 25 ms poll's first sample at **+25 ms** was
-`true`. Print mode exited immediately: `session_shutdown` at **+1 ms** was
-already `true`, and no 25 ms timer could run before process exit. Thus the
-first observed positive print-mode edge was shutdown at +1 ms, not a poll
-sample; this capture does not claim a 25 ms print-mode poll observation.
-The shipped channel's bounded sampler remains necessary for interactive turns.
-
-**4. Approval correlation — pass.** The requested harmless bash command wrote
-`APPROVAL_OK` after the person approved. The emitted pair was:
-
-```text
-tool_approval_requested
-  sessionId: 01a0ec43-c678-746b-afcb-c5f60ce47727
-  toolName: bash
-  toolCallId: toolu_01CLdXCVJgSKBdjCLmYkauyM
-  approvalMode: always-ask
-
-tool_approval_resolved
-  sessionId: 01a0ec43-c678-746b-afcb-c5f60ce47727
-  toolName: bash
-  toolCallId: toolu_01CLdXCVJgSKBdjCLmYkauyM
-  approved: true
-```
-
-Both identifiers and the tool name match; the mode and verdict are explicit.
-
-**5. Shipped-driver live delivery — pass.** Before admission, the integration
-branch's built `st2 driver omp-session` refused the exact candidate:
-
-```text
-Error: omp 18.4.2 is unverified (admitted minors: 18.0.x, 18.1.x, 18.3.x); repeat the docs/vrs/06-omp-driver admission checks before extending the gate
-```
-
-The scratch catalog validated **one agent, zero errors, zero warnings**. With
-only `(18, 4)` temporarily added to the wrapper gate, the same integration
-branch installed immutable hook set
-`sha256-764f9328a8bdd17b4987c958a3eeb1331b817dcdf6546ea24a52045da7e236e7`.
-`st2 driver omp-session` launched `lab.omp1842` in PTY `omp-r05-driver`; the
-injected shipped `omp-channel.ts` used the built `st2 driver omp-channel`.
-Presence reached `available`. After the initial launch turn settled, its
-harness-state record was:

-```
-
-The first Cargo attempt without `CARGO_NET_GIT_FETCH_WITH_CLI=true` could not
-authenticate the pinned private `pty-rust` Git dependency; the retried focused
-run succeeded. The integration branch's `st3` Nix build failed an unrelated
-`github_review_example_removes_its_checkout_and_temp_build_files` test because
-`/bin/sh: /bin/rm: not found`; its binary was subsequently built with tests
-disabled solely for the isolated runtime check.
-
-## Conclusion
-
-All five delivery-critical surfaces pass on omp 18.4.2: extension API,
-lifecycle vocabulary (still no `agent_settled`), first positive sampled
-interactive idle edge, approval correlation, and complete shipped-driver
-message delivery. Admit minor `18.4` beside `18.0`, `18.1`, and `18.3` under
-OMP-R05 and decision 0007-omp-is-a-fifth-native-driver-with-its-own-channel-and-a-hard-version-gate. This does not admit `18.2` and does not change the
-separate exact-build `MEASURED_CONTEXT_VERSIONS` fixture.
-
-## Teardown and residual risk
-
-All three scratch PTYs (`omp-r05-interactive`, `omp-r05-approval`,
-`omp-r05-driver`) were killed and removed; the isolated registry printed `[]`.
-The named isolated daemon was stopped and the short `/tmp/ompr05-1000` socket
-alias removed. No shared daemon was restarted, and the real-home credential
-profile and live PTY registry were not modified.
-
-The approval denial path remains unmeasured. This is one Linux x86_64 capture
-using configured `openai-codex/gpt-6-sol`, not a provider matrix. Print-mode
-shutdown preempted the timer, so print idle timing is bounded only by the
-observed +1 ms shutdown edge. Later 18.4.x patches are intentionally admitted
-without a new capture; later minors remain refused.
-
-## VRS Impact
-
-Extends `SUPPORTED_OMP_MINORS` to `[(18, 0), (18, 1), (18, 3), (18, 4)]`
-and adds exact build `18.4.2` to the literal admission-build test. OMP-R02,
-OMP-R03 and OMP-R05 remain satisfied; no open question is closed.

-# omp 18.6.0 admission checks
-
-## Question
-
-The launch gate admits minors `18.0`, `18.1`, `18.3`, and `18.4`. Does `18.6.0` preserve the five delivery-critical surfaces required by OMP-R05? Unmeasured `18.2` and `18.5` remain refused.
-
-Date: 2026-10-04. Candidate binary:
-`/nix/store/iiab5by2g75lz5vym1pxkq1np9pw3w6q-omp-18.6.0/bin/omp`;
-`--version` printed `omp/18.6.0`. Linux x86_64, model
-`openai-codex/gpt-6.1-sol`, thinking `minimal` for probes 1–4.
-
-## Method for extension, lifecycle, idle, and approval probes
-
-The disposable extension logged event name, timestamp, `ctx.isIdle()`, and the
-approval fields `sessionId`, `toolName`, `toolCallId`, `approvalMode`, and
-`approved`. It registered `session_start`, `agent_start`, `turn_start`,
-`message_start`, `message_end`, `turn_end`, `agent_end`, `agent_settled`,
-`session_shutdown`, `tool_execution_start`, `tool_execution_end`,
-`tool_approval_requested`, and `tool_approval_resolved`. At `agent_end`, a
-25 ms timer sampled idle until the first positive observation or 80 samples.
-
-The exact candidate was launched with:
-
-```sh
-omp --no-session --no-lsp --no-skills --no-rules --no-extensions --no-title \
-  --model openai-codex/gpt-6.1-sol --thinking minimal \
-  -e /tmp/omp186-four/probe.ts -p --no-tools \
-  'Reply with exactly PRINT_OK' </dev/null
-```
-
-The interactive invocation omitted `-p` and asked for `INTERACTIVE_OK` in a
-separate named PTY. Approval used another isolated PTY and
-`--tools bash --no-pty --approval-mode always-ask` with this exact prompt:
-
-> Run exactly this harmless bash command: printf APPROVAL_OK. Request normal
-> tool approval; after execution reply with exactly APPROVAL_DONE. Do not run
-> any other tool or command.
-
-The real login HOME retained existing provider authentication without copying
-or deliberately modifying credentials. XDG configuration, state, cache and
-runtime directories, workspace, and PTY registry were isolated below
-`/tmp/omp186-four`. Fractal identity, hooks, catalog and socket environment
-variables were unset. No shared daemon or mission was operated.
-
-## Results for probes 1–4
-
-**1. Extension load — pass.** Initialization recorded:
-
-```json
-{"sendUserMessage":"function","sendMessage":"function","on":"function","piNamespace":true}
-```
-
-**2. Lifecycle inventory — pass.** Print and interactive turns recorded:
-
-```text
-session_start, agent_start, turn_start,
-message_start, message_end, message_start, message_end,
-turn_end, agent_end, session_shutdown
-```
-
-The interactive shutdown was observed on deliberate PTY stop. Registering
-`agent_settled` succeeded, but neither mode emitted it. The print response was
-`PRINT_OK`; the interactive response was `INTERACTIVE_OK`.
-
-**3. Idle edge — pass.** Print `agent_end` at `20:29:44.890Z` reported
-`idle:false`; shutdown at `20:29:44.891Z` reported `idle:true` (**+1 ms**).
-Process exit prevented any timer sample, so this is a shutdown observation,
-not a claimed poll result. Interactive `agent_end` at `20:29:56.557Z` was
-`idle:false`; the first 25 ms sample at `20:29:56.582Z` was `idle:true`
-(**+25 ms**). The bounded shipped-channel sampler is still required.
-
-**4. Approval correlation — pass.** Johannes selected Approve in the real
-always-ask dialog for `printf APPROVAL_OK`; the worker did not inject an event
-or fabricate a tool result. The pair retained exact matching correlation:
-
-```text
-tool_approval_requested  20:30:05.396Z  approvalMode: always-ask
-tool_approval_resolved   20:34:52.764Z  approved: true
-  sessionId: 01a1089b-f104-77e6-ad91-3ae8c7b40ec4
-  toolName: bash
-  toolCallId: call_LhE2UdpWpDgxVR7uc9W3kHBa|fc_06df411d6e92d138016ac2b74c20b487d299f86acc2513ae3a
-```
-
-`tool_execution_start` preceded the request; `tool_execution_end` followed
-the resolution at `20:34:52.840Z`. Actual tool output was `APPROVAL_OK`, and
-the final reply was `APPROVAL_DONE`. The post-approval `agent_end` again
-reported non-idle, followed by positive idle at the first **+25 ms** sample.
-The provider's current `call_|fc_` tool-call ID spelling differs from the
-prior capture's `toolu_` spelling; correlation requires equality, not a
-provider-specific format.
-
-## Teardown for probes 1–4
-
-Both owned PTYs were killed and removed. The isolated registry's final JSON
-listing was `[]`. Interactive shutdown was logged at `20:30:27.849Z`, and
-approval shutdown at `20:36:34.815Z`. Evidence retained until integration
-included the disposable extension/run script and three JSONL captures; no
-shared daemon, real mission, or provider credential file was modified.
-
-This section measures one Linux x86_64 candidate and one configured model,
-not a provider matrix. Approval denial remains outside this positive capture.
-
-## Shipped-driver native delivery — probe 5
-
-**Pass.** First, deployed `st 0.1.0+8298c70` refused the exact candidate:
-
-```text
-st: omp 18.6.0 is unverified (admitted minors: 18.0.x, 18.1.x, 18.3.x, 18.4.x); repeat the docs/vrs/06-omp-driver admission checks before extending the gate
-```
-
-The measured binary used source revision
-`c9b3662f5153f1f6806bd1d5d700b9b0a31eb0f4` with the sole production change
-of appending `(18, 6)` to `SUPPORTED_OMP_MINORS`. A source snapshot excluded
-Git metadata, so the binary reported `0.1.0+dev`; that banner does **not**
-claim a clean committed revision. Its SHA-256 was
-`7002887b5f96bdb3dff5685b60772c19d5bec2a70e5b277cb64f0eb9f2fd9876`.
-Only `cargo build --locked -p fractal --bin st3 -j 8` was run in the pinned Nix
-development environment on the Linux x86_64 build host, under the shared lock and `nice -n 19`;
-it finished in **2m05s**. No project-wide tests or hosted CI were used for
-this runtime measurement.
-
-A disposable native daemon had distinct state, socket, client-gateway socket,
-workspace, XDG directories, and PTY root. It launched `agent/lab/omp186`
-with model `openai-codex/gpt-6.1-sol`, effort `low`, `restart never`,
-`--no-skills --no-rules --no-lsp --no-extensions --no-title`, and
-`--approval-mode yolo`. The candidate's store directory led the probe PATH;
-the process evidence confirmed that exact candidate, whose SHA-256 was
-`c9af26aaec62a7cafbd0be154d6c31eaeb232b2c49249eded7ee30766f501d4d`.
-Existing real-HOME provider authentication was used without copying credentials.
-The daemon published its own immutable hooks, with no `ST_HOOKS` override:
-
-```text
-hook set: sha256-4eb1d08a9a92fc3ace87cf85b075062dc2ea5f9bf0ccd046e9b940048624f756
-omp-channel.ts SHA-256: 01d94dc2bfbeffd97f37fe3d8f1c5e35af9b6f9b27a3d03086abb05cc366f0fa
-```
-
-After the initial idle observation, real `st conversations send
-agent/lab/omp186` created `message/ef4beb4f5e9744b8`. The message asked only
-for a scratch `delivery-proof.txt` containing `OMP186_NATIVE_DELIVERY_OK`
-without a newline, followed by a reply of `OMP186_NATIVE_DELIVERY_DONE`.
-No PTY input, `pty send`, or terminal injection delivered the message.
-The shipped `omp-channel` consumed it and the graph recorded:
-
-| Observation | UTC time |
-| --- | --- |
-| initial idle | 20:38:58.229Z |
-| message sent | 20:38:58.278Z |
-| working | 20:38:58.735Z |
-| exact assistant reply | 20:39:07.096Z |
-| returned idle | 20:39:07.495Z |
-
-`working` is the current graph equivalent of the legacy capture's `active`.
-All observations retained incarnation
-`2685178:2026-10-04T20:38:56.932Z` and native OMP session
-`01a108a4-23dd-7129-8757-e3ff177ca495`. The file had exactly **25 bytes**,
-`OMP186_NATIVE_DELIVERY_OK`; the native assistant record had exactly
-`OMP186_NATIVE_DELIVERY_DONE`, `stopReason:"stop"`, and the expected model.
-Final delivery was `state:"current", transport:"omp-channel"`.
-This is completed message consumption, not merely transport acceptance.
-
-The first admitted attempt had an erroneous empty scratch `ST_HOOKS`
-override; removing it restored daemon-owned immutable hook publication.
-The successful run's orchestration initially waited for legacy `active`
-instead of current `working`. Retained snapshots, native reply, and exact
-marker proved the successful run; no second provider run manufactured those
-observations.
-
-All three scratch daemons were stopped, every created PTY was killed and
-removed, all isolated registries returned `[]`, and the final scan found no
-process for any owned PTY root. The real-HOME Fractal skill was byte-identical
-before and after. Runtime state, copied source, dependencies, and disposable
-scripts were removed. No shared daemon or real mission was changed.
-
-## Focused regression verification
-
-The updated gate was tested in the pinned Nix development environment,
-under the shared Linux build lock and `nice -n 19`:
-
-```text
-$ cargo test --locked -p fractal-drivers --lib omp_session::tests -j 8 -- --nocapture
-running 19 tests
-test result: ok. 19 passed; 0 failed; 0 ignored; 0 measured; 913 filtered out
-```
-
-The existing admission tests now cover `18.6.0`, a future patch `18.6.99`,
-rejection of unmeasured `18.5`/`18.7`, and rejection of `18.6` prerelease
-and build-metadata banners. Compilation completed in 34.81s; the scoped
-tests finished in 13.47s. This is not a project-wide gate receipt.
-
-## Conclusion
-
-All five OMP-R05 surfaces pass on 18.6.0. Admit minor `18.6` alongside
-`18.0`, `18.1`, `18.3`, and `18.4`; do not admit unmeasured minors or
-prereleases, and do not change the separate exact-build harness-context
-measurement fixture. This capture proves one Linux x86_64 candidate with one
-configured provider/model, not every provider, denial path, steer/modal
-interaction, or context-arithmetic build.

-# omp driver open questions
-
-Each entry links a spec `DQ-OMP-*`. Questions leave this file when resolved — into
-[spec.md](./spec.md) as decisions or `.experiments/` as tested hypotheses.
-
-- **DQ-OMP-1 Deny-path semantics.** What omp does after
-  `tool_approval_resolved { approved: false }` — whether the turn ends (Claude's deny path:
-  turn ends eventlessly) or the model continues with a denial result. Until captured,
-  OMP-T01 accepts a possibly brief misprojection of activity after a denial.
-- **DQ-OMP-2 Ask-axis discrimination.** Whether an AskUserQuestion-equivalent surface in omp
-  arrives as `tool_approval_requested` with a distinguishable `toolName`, so v1's coarse
-  `ask: permission` can be split into question vs permission like the Claude driver does.
-  Needs one capture of each prompt kind under forced approval mode.
-- **DQ-OMP-3 Mid-turn steer in the live TUI.** `deliverAs: "steer"` was accepted without
-  error in print mode; the interactive visual (message lands as a queued steer, not a lost
-  send) is unconfirmed. Resolves by repeating the delivery experiment with the trigger fired
-  during an active turn and reading the resulting transcript.
-- **DQ-OMP-4 Modal interaction.** pi's capture showed an open `/model` modal does not corrupt
-  idle delivery; omp's equivalent has not been tested. Same method: open a picker, deliver
-  while idle-true, verify the modal survives.
-- **DQ-OMP-5 Update-banner suppression.** Interactive boots showed the update banner;
-  whether `PI_OFFLINE` / `PI_SKIP_VERSION_CHECK` suppress it was not establishable in print
-  mode. Resolves by one interactive boot with the env set. The wrapper ships the env either
-  way (harmless if inert).

-# omp driver requirements
-
-## Context
-
-This subsystem specifies the omp native driver: the typed `omp` driver block, its expansion,
-the session wrapper, and the injected-extension channel that delivers st2 messages and
-publishes observed harness state. It refines two existing subsystems rather than replacing
-them: typed driver blocks are defined by [`02-agent-spec`](../02-agent-spec/), and the
-observed-harness-state record this driver writes is defined by
-[`05-harness-state`](../05-harness-state/). The delivery principle is
-[decision 0005](../.decisions/0005-pi-delivers-natively-through-an-injected-extension.md)
-(native extension delivery, never DING screen-scraping), applied to a fifth harness; the
-driver-level choices are recorded in
-[decision 0007](../.decisions/0007-omp-is-a-fifth-native-driver-with-its-own-channel-and-a-hard-version-gate.md).
-Where this file and those disagree, they win and this file is wrong.
-
-omp is an earendil-works/pi-family harness: it loads pi-style TypeScript extensions and reads
-pi's env fallbacks. Measured integration evidence:
-[`2026-08-25-omp-harness-integration.md`](./.experiments/2026-08-25-omp-harness-integration.md).
-
-## Assumptions
-
-- **OMP-A01 omp keeps its pi-compatible extension surface:** the three calls the channel uses
-  (`sendUserMessage`, `sendMessage`, `on`) keep their names, signatures, and event-name
-  vocabulary. The hard version gate (OMP-R05) exists because this assumption is versioned,
-  not guaranteed.
-- **OMP-A02 Unattended seats run with approvals resolved:** like every other maintained
-  driver, a declared seat is expected to launch with an approval mode that does not block on
-  a human; the blocked-on-human axis exists to report the cases where it blocks anyway.
-- **OMP-A03 Trusted writers:** as in OHS-A03 — the wrapper and its channel subprocess are
-  trusted writers of catalog state under the trusted-fleet model.
-
-## Requirements
-
-- **OMP-R01 Full native driver parity.** A declared `driver omp` seat gets: pure KDL
-  expansion from the typed block, a wrapper owning the presence lease and the terminal
-  observed-state record, native inbox delivery through the injected channel, and live
-  active/idle/blocked observations. No DING screen adapter is required for correctness;
-  delivery never depends on reading the pane.
-- **OMP-R02 Observed axes.** The driver publishes `active` on turn start, `idle` on the
-  settled edge (`agent_end` then `isIdle()` true), and `blockedOn: human` between
-  `tool_approval_requested` and `tool_approval_resolved`, whose `approved` payload is the
-  exit edge back to the prior activity. Lost evidence stops the heartbeat per the generic
-  record rules.
-- **OMP-R03 Idle edge without `agent_settled`.** Because omp lacks pi's `agent_settled`
-  event, the channel samples `ctx.isIdle()` after `agent_end` until positive idle evidence
-  or superseding activity, session, or channel ownership. Slow final unwind must not lose
-  the idle edge. Neither `agent_end` itself nor elapsed time proves idle; a pending human
-  ask or approval prevents an idle observation.
-- **OMP-R04 Own channel asset.** omp gets its own `omp-channel.ts`, forked from the pi
-  channel's frame discipline, not a shared file parameterized at runtime — the idle-edge and
-  approval logic differ, and a shared file would make each harness's correctness depend on
-  the other's branch.
-- **OMP-R05 Hard measured admission.** Before owning the live seat, the wrapper measures
-  each unseen exact installed producer and shipped extension in an isolated scratch RPC session.
-  Extension load, lifecycle names, the positive post-`agent_end` idle edge, harmless approval
-  correlation, and completed consumption of one native delivery must all pass. Transport
-  acceptance is separate evidence. Cache the exact release with executable, package manifest and
-  available lockfile, interpreter, extension and probe identity; a same-version executable or
-  metadata replacement cannot reuse a pass. Never traverse the whole installation or refuse a
-  build for installation size.
-  A failed or indeterminate check refuses launch and names the boundary in doctor and agent
-  state. Empty HOME/XDG/workspace/PTY roots and a loopback model isolate managed seats,
-  credentials and history. A new passing version needs no allowlist or st update.
-  A person may explicitly bypass admission for one exact executable/interpreter/installation
-  and shipped extension with `st admission override omp --binary <path> --reason <reason>`.
-  Record this separately from measured evidence; retain refusals, identify the exception in
-  driver logs, and never transfer it to a replacement build/extension. `st admission revoke`
-  restores the normal gate on next launch. Admission does not stop an already-running provider;
-  there is no last-admitted-executable fallback.
-- **OMP-R06 Provider credential rejection is classified, not guessed.** A turn that ended on a
-  provider error carries omp's own `errorId` classification bitfield to st2 unchanged; st2, not
-  the asset, decides whether it names a rejected credential, and publishes the shared
-  `providerAuth`/`providerAuthRejected` boundary (OHS-R16) when it does. The verdict is
-  `AuthFailed` set with `UsageLimit`, `AccountPolicy`, and `Transient` clear, on a value whose
-  `Class` bit proves it is a classification and not a bare HTTP status: omp sets `AuthFailed`
-  from prose containing `401`, `403`, or `forbidden` as readily as from a status, so that flag
-  alone would report an exhausted allowance as a refused credential. A turn omp will retry
-  (`willContinue`) claims neither edge, and only a turn that reached its ordinary end clears a
-  standing rejection. st2 holds no credential knowledge and no remedy beyond the shared generic
-  repair text.
-
-## Acceptable Tradeoffs
-
-- **OMP-T01 Deny-path window.** On `tool_approval_resolved { approved: false }` the channel
-  clears the blocked state immediately; whether omp ends the turn or continues (Claude's deny
-  path ends it eventlessly) is unmeasured until DQ-OMP-1's capture. v1 accepts a possibly
-  brief misprojection there.
-- **OMP-T02 Ask axis coarse-grained.** Every approval projects to `ask: permission` in v1;
-  distinguishing question-form prompts (Claude's `tool_name` rule) awaits DQ-OMP-2.
-- **OMP-T03 No ding composer adapter.** When the channel is dead, delivery fails closed and
-  presence decays; no screen-scrape fallback is built for omp in v1, matching the pi and
-  opencode drivers.
-
-## Delimiters
-
-Not this subsystem: the harness-state envelope and freshness rules
-([`05-harness-state`](../05-harness-state/)); driver-block KDL grammar
-([`02-agent-spec`](../02-agent-spec/)); DING transports
-([`01-ding`](../01-ding/)). Open questions live in
-[open-questions.md](./open-questions.md).

-# Resync composition prototype: watch → classify → occurrence-keyed emit → inbox
-
-## Question
-
-Does the composed mechanism work end to end against the real filesystem and the
-real stream ingress — a carrier change produces exactly one superseded inbox
-event; equal-byte rewrites stay silent; repeated digest transitions remain
-distinct occurrences; failed publication retries one immutable occurrence;
-silent-class stores never notify; whole-file replacement by rename stays
-visible?
-
-## Method
-
-Direct test-first implementation on the feature branch (decision Q6), no
-throwaway spike. Three integration tests in `tests/resync.rs` exercise
-`ResyncSupervisor::spawn` + `refresh` against a real temp catalog, the real
-inotify backend, and the unchanged `fractal_legacy_runner::event::emit` ingress:
-
-1. `carrier_change_emits_one_superseded_resync_event_and_silent_stores_stay_quiet`
-   — seeds baselines silently, then asserts: goal write → exactly one event
-   (`stream: resync`, `binding: goal`, subject `resource goal changed`);
-   equal-content rewrite → no second event; write into
-   `resources/context/` → no event; changed content → fresh event under the
-   same key (event-id changes, supersession retires the predecessor).
-2. `whole_file_declaration_replacement_by_rename_notifies_immediately`
-   — configuration-management style write-then-rename over `agent.kdl`
-   notifies through the parent-directory watch.
-3. `declaring_the_reserved_resync_stream_is_refused` — a declared
-   `stream "resync" {}` fails discovery with the reservation error.
-
-Plus unit tests in `src/resync.rs` for watch-set resolution (`file://`,
-catalog-relative, non-local schemes), classification (goal immediate,
-agent-authored stores excluded), and the built-in-stream carve-out is covered
-by tests 1–2 passing through real `emit`.
-
-Q13 occurrence identity is covered by four focused unit tests in
-`src/resync.rs`:
-
-4. `repeated_identical_transitions_receive_distinct_occurrence_identities` —
-   drives A→B, B→A, A→B through the real event ingress and proves the repeated
-   A→B legs have distinct IDs and subscription sequences 1 and 3.
-5. `failed_tombstone_emit_retains_present_state_and_immutable_retry_snapshot` —
-   proves a failed tombstone retains the exact immutable body, event ID, state,
-   and sequence across same-byte recreation.
-6. `subscribers_advance_occurrence_sequences_independently` — proves two
-   subscriptions each capture their first transition at sequence 1.
-7. `supervisor_restart_incarnation_changes_the_occurrence_namespace` — proves
-   an incarnation change produces a different body and ID even when the
-   per-subscription sequence and digest transition repeat.
-
-Q21 carrier-state semantics are covered by three additional focused tests:
-
-8. `deletion_and_same_byte_recreation_are_distinct_carrier_transitions` —
-   proves present→missing emits `old: <digest>` / `new: missing`, repeated
-   missing stays silent, and same-byte recreation emits missing→present as the
-   next occurrence while superseding the tombstone.
-9. `initial_transient_read_failure_schedules_a_baseline_retry` and
-   `transient_permission_error_retries_without_emitting_a_tombstone` prove an
-   initial or later permission failure retains unknown/prior state and
-   schedules retry; after access recovers, baseline seeding or the real byte
-   transition completes without an intermediate tombstone.
-10. `digesting_a_fifo_fails_without_blocking_the_worker` — proves both native
-    and confined readers classify a FIFO as stable missing without blocking.
-
-Three design constraints were discovered by running the code, not by reasoning:
-
-- **Directory-creation blind spot.** Writing a file into a newly created
-  subdirectory generates events on the new directory's inode, which carries no
-  watch yet. The fix dirties all carriers beneath any mutated path that is an
-  ancestor of carriers and extends watches at that moment
-  (`Worker::mark_mutated`). Reasoned-through designs missed this; the failing
-  test found it.
-- **Shutdown self-deadlock.** The worker's own watcher holds the last mailbox
-  `Sender`, so channel disconnection could never fire while `join` waits. The
-  worker exits on an explicit `Msg::Shutdown` sent by `Drop`.
-- **Refresh reseeding erases in-flight events.** A reconcile pass can land
-  between a carrier mutation and its flush window — declaration changes wake
-  reconcile immediately, so this fires every time a declaration is replaced.
-  Reseeding digests on watch-set application silently dropped that event; the
-  eval cell caught what the Rust tests missed because only the resident
-  supervisor loop races refresh against mutation processing.
-
-## Result
-
-The default resync unit slice passed 31 tests, including every Q13/Q21 state,
-retry, shared-subscriber, and confinement case. The default Agent Spec suite
-passed 78 tests, and the `wasm-resolver` Agent Spec suite passed 110 unit,
-integration, and hostile-module tests. The real resync integration suite passed
-three default and five wasm-enabled filesystem/inbox cases. Pre-existing
-warnings were unchanged.
-
-## Conclusion
-
-The composition holds without new delivery semantics: DING, archive, ring
-dedup, and supersession are inherited untouched. Carrier absence is now a
-first-class transition without turning transient read failures into false
-tombstones.
-
-## VRS Impact
-
-Supports [`06-resync/requirements.md`](../../06-resync/requirements.md)
-RESYNC-R01/R03/R04/R06/R07 and [`spec.md`](../../06-resync/spec.md). The
-Q13/Q21 evidence supports the approved RESYNC-R06 occurrence and carrier-state
-amendments to decision record 0008. The catalog-relative resource URI form
-remains an st2 extension pending canonical Agent Spec adoption (noted in
-[`02-agent-spec`](../../02-agent-spec/requirements.md) terms).

-# Resync requirements
-
-## Context
-
-This subsystem defines resync events: supervisor-emitted notifications that
-tell a live agent one of its declared resource carriers changed on disk, so
-the session can re-read it without a restart. The analogy is hot module
-replacement for context: the running process stays up; the changed module
-(the carrier) is swapped underneath it and the process is told which module
-to reload.
-
-Delivery rides the declared event-stream machinery ([`04-stream`](../04-stream/requirements.md))
-through a built-in per-agent `resync` stream that exists without declaration.
-The decision records are [`.decisions/0008`](../.decisions/0008-resync-events-ride-the-built-in-stream.md);
-watch scope, noise model, and event identity were settled with the principal
-on 2026-08-25 (decision requests Q1–Q6). Filesystem watching refines root
-[`R14`](../requirements.md) (explicit filesystem-event contracts) and
-[`R15`](../requirements.md) (bounded event coalescing); delivery inherits
-root [`R05`](../requirements.md); Resource bindings are defined by
-[`02-agent-spec/F07`](../02-agent-spec/spec.md) and root [`R20`](../requirements.md)/[`R21`](../requirements.md).
-
-## Assumptions
-
-- **RESYNC-A01 Local carriers only:** A carrier is watchable iff its binding
-  URI denotes a local regular file: an absolute `file://` URI, a
-  catalog-relative path resolved against the agent's directory, or a scheme URI
-  successfully resolved to a contained local path by a declared
-  [`07-resource-profile`](../07-resource-profile/requirements.md). Bindings
-  whose scheme has no registered profile, or whose registered profile fails,
-  are never watched and never stop the supervisor; their watchability remains
-  observable through catalog inspection. The agent's own declaration file is
-  covered by the existing declaration watcher and is also a resync source.
-- **RESYNC-A02 Trusted fleet:** The supervisor is the only resync producer;
-  it runs inside the owner host's existing trust domain (root `A02`). No new
-  authentication surface exists.
-- **RESYNC-A03 Equal bytes mean equal state:** For an on-disk carrier,
-  content equality is state equality, so an equal-byte rewrite is suppressed
-  before event capture. Distinct observed transitions remain distinct
-  occurrences even when they repeat the same old/new byte states.
-
-## Acceptable Tradeoffs
-
-- **RESYNC-T01 Static classes, no write attribution:** Classification comes
-  from a Resource Profile declaration for profile-resolved carriers and from
-  fixed path roles for native local carriers; it does not infer who wrote the
-  change. An external edit into a store the agent authors (context, decisions)
-  is silent by classification; a st2-mediated write to an immediate-class
-  carrier would notify. True authorship attribution is deferred until evidence
-  shows the gap matters.
-- **RESYNC-T02 Provisional windows:** Coalescing window lengths ship as
-  provisional constants tuned by observation, per the rollout note in
-  [issue #341](https://github.com/compoundingtech/st2/issues/341).
-- **RESYNC-T03 No catch-up:** Like any restarted stream, a restarted
-  supervisor re-observes current carrier state silently and emits only
-  subsequent changes. Changes missed while the supervisor was down are
-  discovered by the agent's own next read or by reconcile, not reconstructed
-  as events.
-
-## Requirements
-
-### Must observe declared carriers
-
-- **RESYNC-R01 Watch set:** While an agent is running on this host, the
-  supervisor watches exactly the local files denoted by that agent's active
-  resource bindings, the opt-in ancestor carriers required by `RESYNC-R09`,
-  plus its own declaration file. The watch attaches to each carrier's parent
-  directory non-recursively and tracks directory identity so whole-file
-  replacement by rename keeps working. Nothing outside this set is watched;
-  installation failure degrades to timer-based digest polling rather than
-  losing the capability.
-- **RESYNC-R02 Explicit watch contract:** The resync watcher states what it
-  watches and why, denies everything else by default, ignores read/open
-  access events, and never traverses payload trees — refining [`R14`](../requirements.md)
-  and the mutation-only wakeup invariant.
-- **RESYNC-R03 Seeded baseline:** On supervisor start and at every live-seat
-  transition, every watchable carrier is recorded as either
-  `present(<content-digest>)` or `missing` without emitting. Only a transition
-  between proven states produces an event; a restart alone wakes nobody.
-  Permission and transient I/O failures establish neither state and are retried
-  rather than interpreted as absence.
-
-### Must classify before notifying
-
-- **RESYNC-R04 Class defaults:** Each carrier belongs to exactly one class:
-  *immediate*, *silent*, or *coalesced*. A profile-resolved carrier takes the
-  trusted class declared beside its resolver; `silent` excludes it from the
-  watch set. Native local carriers use fixed path defaults: immediate for the
-  agent's declaration file and goal carriers, silent for stores under the
-  agent directory that it authors (context, decisions, friction logs), and
-  coalesced for every other local carrier. Immediate changes notify within a
-  short coalescing window; coalesced changes notify within a longer window; a
-  burst of mutations collapses to one notification pass per window.
-- **RESYNC-R05 Bounded coalescing:** Window behavior is bounded and tested
-  per [`R15`](../requirements.md): emissions happen at window boundaries, not
-  per writer event, and a fast-rewriting carrier cannot produce unbounded
-  notifications.
-
-### Must emit honest, deduplicated events
-
-- **RESYNC-R06 Event shape and occurrence identity:** One carrier state change
-  becomes one stream event on the built-in `resync` stream: subject
-  `resource <binding> changed`, body naming the binding label, resolved path,
-  old and new carrier states, and an occurrence token. A present state renders
-  as its content digest and absence renders canonically as `missing`, so
-  deletion and recreation are observable even when recreated bytes equal the
-  prior bytes. The token combines the current supervisor incarnation —
-  catalog-lock device/inode plus supervisor PID/start-time ticks — with a
-  sequence retained independently by each subscription. A subscription
-  advances its sequence only when it captures a new immutable transition; a
-  failed publication retries the same body, token, and identity. The event
-  identity is the SHA-256 of that canonical rendered body. Thus replay is
-  stable, while repeated state-transition legs receive distinct identities.
-  The grouping key is the binding label; every emit declares supersession so a
-  binding collapses to one unread head.
-- **RESYNC-R07 Built-in stream:** The `resync` stream exists on every agent
-  without declaration and is reserved: a user-declared stream of that name is
-  refused. Only the supervisor's crate-internal publisher admits the built-in
-  stream; public event ingress remains declaration-gated. After that admission,
-  publication reuses the ordinary ring deduplication, receipt validation,
-  supersession semantics, inbox transport, and DING `»` marker inherited from
-  [`STREAM-R03..R07`](../04-stream/requirements.md).
-- **RESYNC-R08 Lifecycle honesty:** No events accumulate for suspended or
-  retired agents. Carrier-state seeding happens when a seat launches or
-  resumes, so resume re-observes current state silently and only later
-  transitions notify.
-
-### Must compose and install complete live views
-
-- **RESYNC-R09 Opt-in supervisor-chain coverage:** When a profile declares
-  `notify-chain`, a live agent's watch set also contains every active
-  same-profile-scheme carrier declared by each non-retired supervisor ancestor.
-  A suspended ancestor remains a layer and traversal continues through it, but
-  the suspended seat itself owns no active subscription. A retired ancestor
-  contributes no layer and traversal continues through it. Profiles without the
-  flag and native bindings retain agent-local coverage. A missing, cyclic,
-  ambiguous, or otherwise unwalkable supervisor chain is diagnosed; it never
-  becomes a silent guessed chain.
-- **RESYNC-R10 Launch-boundary completeness:** A canonical seat's complete
-  catalog-aware watch set is installed synchronously when reconciliation first
-  proves the seat live and before any later launch target may block. Reinstalling
-  an already-live seat is idempotent: unchanged own and ancestor subscriptions
-  retain their baselines and pending transitions. Full refresh remains the final
-  authority for lifecycle removal and hot profile reload. It selects active
-  subscriptions only from canonical seats proven live in the pass while resolving
-  their topology against every valid discovered declaration, including suspended
-  and retired nodes.
-
-## Evidence
-
-The composition (parent-directory watch → classification → carrier-state-keyed
-superseded emit → DING wake) is proven by integration tests introduced with the
-implementation; see [`.experiments/`](./.experiments/) for the record and the
-pre-existing failure baseline it was verified against.

-
-## Carrier resolution
-
-A binding URI resolves to a watchable local path in this precedence order:
-
-1. A URI whose exact scheme has a declared
-   [`07-resource-profile`](../07-resource-profile/spec.md) resolves through that
-   profile to a host-contained path and declared notification class.
-2. An unregistered absolute `file://` URI uses its lexically cleaned path
-   component (`.`/`..`) without following symlinks.
-3. A catalog-relative path with no scheme resolves against the agent's
-   declaration directory and is lexically cleaned the same way.
-
-Any other unregistered scheme is not watchable. A registered profile that
-cannot load or resolve also leaves only that binding unwatchable; it never
-falls back to a guessed local rule or stops the supervisor. Watchability of
-every active binding is projected into `st2 agents --json` as part of the
-declared Resource projection so absence of coverage is observable.
-
-## Supervisor-chain composition (RESYNC-R09..R10)
-
-```text
-root goal carrier ───────────────┐
-                                 v
-root seat <- supervisor - lead seat <- supervisor - worker seat
-                    goal carrier ────────────────> worker watch set
-worker goal carrier ────────────────────────────> worker watch set
-```
-
-For each active binding whose registered profile declares `notify-chain`, watch
-resolution first resolves the binding's own carrier, then validates and walks
-the seat's supervisor chain against the pass's complete discovered spec vector.
-At every non-retired ancestor it resolves active bindings with the same profile
-scheme against that ancestor's own declaration directory. Each inherited
-subscription retains the ancestor's binding label qualified by immutable agent
-ID (`goal@<agent-id>`), so address changes cannot create a new supersession key
-and mutations in two layers cannot share one.
-A suspended ancestor contributes its layer and traversal continues, but the
-suspended seat itself owns no active subscription. A retired ancestor
-contributes no layer, but traversal continues to its ancestors.
-
-Chain membership comes only from a profile's trusted opt-in flag and exact URI
-scheme. Binding labels do not define composition, native local bindings never
-gain it implicitly, and profiles without the flag remain agent-local. A
-missing, ambiguous, cyclic, cross-host, or otherwise unwalkable supervisor edge
-produces a reconcile diagnostic and no invented ancestor subscription. Profile
-resolution failures remain contained to the failed carrier.
-
-The live-install API takes both the canonical seat and the complete discovered
-spec vector. It resolves the complete own-plus-ancestor set under the
-supervisor's current profile registry, sends one targeted watch-set replacement,
-and waits for the worker acknowledgement. Reinstalling the same identity and
-paths preserves carrier baselines, occurrence sequences, dirty state, and
-pending transitions.
-
-## Classification
-
-Classification is decided before a path enters the watch set:
-
-| Source | Class | Window |
-| --- | --- | --- |
-| profile-resolved carrier | the trusted `class` beside the catalog's resolver module | `immediate`: short; `coalesced`: long; `silent`: excluded |
-| native declaration | immediate | short (500 ms provisional) |
-| native local carrier named `goal` or with basename `goal.md` | immediate | short (500 ms provisional) |
-| native local path under `resources/context`, `resources/decisions`, or `resources/friction` | silent | excluded |
-| every other native local carrier | coalesced | long (5 s provisional) |
-
-Profile class takes precedence over basename/path heuristics; the guest module
-cannot choose it. Windows are constants in one place, named as provisional,
-and tuned by observed notification volume (issue #341 rollout note). A burst
-inside a window collapses to one pass; when subscribers of different classes
-share a path, each remains dirty until its own class window. Within one due
-class each changed carrier gets its own event so per-binding supersession stays
-meaningful.
-
-## Watcher mechanics
-
-- One non-recursive inotify watch per distinct parent directory of the watch
-  set, registered through the same `notify` backend and mutation-only filter
-  as [`src/watch.rs`](../../../src/watch.rs). Parent-directory watching is
-  what makes whole-file replacement by rename visible: the watch attaches to
-  the directory inode, which survives its children being replaced.
-- Directory identity tracking plus event-time invalidation re-registers on
-  same-path replacement, mirroring `CatalogDeclarationWatcher`.
-- The watcher owns no reconcile authority: a resync mutation does not wake a
-  full-catalog pass. It shares only the observation primitives.
-- Before lifecycle execution, each pass synchronously upserts the complete
-  catalog-aware watch set for every successfully compiled canonical seat it
-  observed alive. A successful canonical launch or restart performs the same
-  acknowledged upsert at the exact live transition before execution advances
-  to any later task. Both paths resolve supervisor-chain carriers against the
-  complete discovered spec vector, never a one-spec view.
-- Publication runs on a dedicated thread, never the thread that answers a pass's
-  acknowledged upserts, so a pass completes while publications are pending,
-  refused, or blocked on another process's lock. The watcher thread captures a
-  transition, hands it off, and applies the outcome when it returns, remaining
-  the only writer of carrier state; re-observing the carrier after an outcome is
-  what schedules the next attempt. One publication is outstanding per
-  subscription at a time. A queued publication is dropped when its subscription
-  is deactivated or removed by a refresh, while one the emitter already started
-  completes with its outcome discarded, so nothing is published to a seat whose
-  subscription the pass has already removed.
-- After lifecycle execution, each reconcile pass atomically refreshes the watch
-  set through separate catalog and subscription inputs. The catalog input is
-  every valid discovered declaration, including suspended and retired topology
-  nodes; it is used for chain traversal only. The subscription input is agents
-  whose canonical seat was observed alive or successfully launched/restarted in
-  that pass; only those agents receive own or inherited watches. This refresh
-  owns removals, malformed declaration retention, and hot profile replacement.
-  Desired declarations, dead keep-retained seats, and companion-only launches
-  never become watched.
-  If strict discovery temporarily rejects a declaration whose exact canonical
-  seat remains observed alive, its prior declaration subscription survives with
-  its carrier state and pending transition; it drops as soon as that seat is
-  not live. Existing valid subscriptions are matched by immutable agent ID and
-  binding label. Each refresh takes agent ID, current bus address, canonical
-  seat ID, carrier path, label, and class from the current declaration while
-  retaining carrier state, the per-subscription occurrence sequence, any
-  immutable pending transition, and dirty state; only new subscriptions seed
-  silently with sequence zero.
-- A previously blind path is state-diffed both before and after its recovered
-  parent watch is registered, closing the poll-to-registration gap.
-- Installation failure degrades to timer-based carrier polling over the watch
-  set (bounded by the number of bindings), never to silence about the
-  mechanism. Polling only marks observed changes dirty and schedules the
-  carrier's ordinary class deadline; it neither bypasses coalescing nor emits
-  ahead of an immutable pending transition.
-- A runtime watcher-backend error may mean mutation events were dropped, so it
-  schedules every changed carrier through the same pending-aware classified
-  path. Equal states remain silent.
-- A change to the registration set is read as the same kind of drop, for the
-  whole watch set and not only the directories that changed. A backend is not
-  obliged to leave its other subscriptions undisturbed while it registers or
-  drops one: `notify`'s macOS FSEvents backend stops the single shared stream
-  on every watch and unwatch, purges the device's pending events, and restarts
-  at `kFSEventStreamEventIdSinceNow`, so a mutation already queued for a
-  directory that never left the set is destroyed. Linux inotify keeps its queue
-  across descriptor changes. Every subscribed carrier is therefore re-diffed
-  whenever a registration actually changed, through the same classified path;
-  equal states remain silent, so the recovered mutation is the only thing that
-  emits.
-- Reads open carriers nonblocking and without following the final symlink
-  (every component for confined carriers). A proven regular file becomes
-  `present(<sha256>)`; `ENOENT` or a stable non-regular replacement becomes
-  `missing`. Permission and transient I/O errors are diagnosed and retried
-  without changing state. FIFOs and other special files therefore cannot stall
-  the worker and produce one tombstone transition rather than silent ambiguity.
-
-## Built-in stream
-
-`emit_builtin_resync` is crate-internal, fixes the stream name to the reserved
-`resync` value, and is called only by the supervisor's resync watcher. Public
-`event::emit` and the CLI always require the recipient to declare the requested
-stream, so neither can claim or supersede built-in resync events. Both admission
-paths then share the same host ownership, desired-state running,
-owner-binding validation, catalog-lock serialization, event validation, and
-ring transaction implementing [`STREAM-R03..R05`](../04-stream/spec.md).
-Declaring a stream named `resync` in an Agent Spec is a validation error:
-the reservation must not be shadowable. Resource binding names use the event-key
-grammar (1..=200 bytes, no surrounding whitespace or controls), and
-`declaration` is reserved for the synthetic declaration carrier so supersession
-keys cannot collide.
-
-Carrier state and occurrence-sequence state live with the supervisor process
-(seeded at start) and have no durable store, consistent with RESYNC-T03. A
-carrier state is `present(<sha256>)` or `missing`. Present→missing emits a
-canonical tombstone whose body contains `old: <digest>` and `new: missing`;
-missing→present emits a creation even when that digest matches the bytes from
-before deletion. Repeated missing observations are silent.
-
-A captured transition gets an occurrence token
-`v1:<catalog-lock-dev>:<catalog-lock-inode>:<supervisor-pid>:<supervisor-start-time-ticks>:<subscription-sequence>`
-in its canonical body before that body is hashed for the event ID. Each
-subscription advances its sequence only when capturing a new immutable
-transition. Failed publication retains the old state, exact target state,
-canonical body, occurrence token, and event ID; retry replays those bytes
-before observing newer carrier state. Repeated transition legs therefore
-remain distinct occurrences, while a retry remains the same reservation. A
-supervisor restart changes the incarnation namespace and silently seeds new
-subscription sequences. The durable dedup horizon remains the stream receipt
-ring.
-
-A failed publication is classified by what could admit it later, because eligibility is resolved
-under the catalog-authoring lock and a refusal therefore follows from the declaration rather than
-from timing. Retrying one is pure cost: every attempt re-resolves the catalog to reach the same
-answer.
-
-- A recipient that is declared but not running parks its reservation. The subscription captures
-  nothing and schedules nothing while parked, and the reservation is retained beyond the
-  subscription itself, which the next refresh drops. It re-arms with its exact reserved bytes when
-  a refresh carries that recipient again, which happens only while it is running. Dropping it at
-  the refusal would instead lose a resync the agent should see on resume.
-- An ambiguous recipient, a recipient owned by another host, and a recipient that does not declare
-  the stream are refused permanently. The reservation is dropped after one diagnostic, and the
-  carrier baseline advances so the same transition is not captured again.
-- Everything else is retryable, including an absent declaration and a catalog mid-edit: a
-  declaration being replaced by rename is briefly absent, so its reservation is kept.
-
-## What this does not do
-
-- No `notify` attribute on resource bindings (deferred until volume data
-  justifies per-binding overrides).
-- No remote/non-local carrier watching.
-- No write attribution beyond static classes (RESYNC-T01).
-- No catch-up replay of missed changes (RESYNC-T03).
-- No implicit supervisor-chain inference for native bindings or profiles that
-  do not declare `notify-chain`.

-# Dotfiles real-shape Resource Profile end-to-end proof
-
-## Question
-
-Does the feature-gated wasm Resource Profile work through the full resident st2
-runtime against the real Nix-generated standing-seat declaration shape —
-profile parsing, URI resolution, watch installation, whole-file replacement,
-event delivery, equal-byte suppression, teardown, and deterministic replay?
-
-## Method
-
-The experiment used the built `wasm-resolver` st2 binary and the packaged
-agent-goal resolver module. It assembled a fresh scratch catalog at
-`/tmp/resync-real-e2e/net` from the real standing-seat shape:
-
-```kdl
-catalog {
-  pty-root "pty"
-}
-
-profile "dev.schickling.agent-goal" {
-  wasm "/nix/store/...-agent-goal-resolver-wasm-0.1.0/lib/agent-goal-resolver.wasm"
-  class "immediate"
-}
-```
-
-The agent declaration retained the production-generated structure: `meta {
-managed-by "nix" }`, identity `cos`, the ordinary argv and DING tasks, and:
-
-```kdl
-resource "goal" \
-  reason="The durable mission, deliverables, acceptance criteria, and boundaries for this agent." \
-  uri="dev.schickling.agent-goal://dev3/cos"
-```
-
-`resources/goal.md` began as `mission v1`. Each run performed:
-
-1. `st2 validate --catalog net --host e2eresync --strict`.
-2. Start resident `st2 up --catalog /tmp/resync-real-e2e/net` and verify the
-   agent PTY and DING exec task were live through `st2 tasks --json` plus the
-   child process.
-3. Stage `mission v2` in a sibling file and rename it over `goal.md`, matching
-   Nix activation's whole-file write-then-rename shape.
-4. Wait up to 20 seconds for the inbox event, then assert its producer, stream,
-   key, subject, event identity, binding/path body, and old/new file digests.
-5. Replace the file again with byte-identical `mission v2`, wait two seconds,
-   and assert the inbox still contained exactly one event.
-6. Stop the resident supervisor, run `st2 down`, and assert no scratch PTY,
-   DING, or child process survived.
-7. Delete and rebuild the scratch state, then repeat the complete flow to check
-   determinism across fresh runs.
-
-The authority in the binding URI intentionally remained `dev3/cos`: the
-profile is selected by scheme, and the guest maps the logical goal identity to
-the local seat's `resources/goal.md`. Only the execution host label changed for
-the safety reason below.
-
-## Result
-
-Both fresh runs passed every step.
-
-| Stage | Proof |
-| --- | --- |
-| Strict declaration | `0 errors, 0 warnings across 1 agent`, exit 0, with the top-level profile block |
-| Resident runtime | agent PTY and DING exec tasks running with fresh scratch processes |
-| Wasm resolution | scheme URI resolved to `/tmp/resync-real-e2e/net/agents/e2eresync/cos/resources/goal.md` with class `immediate` |
-| Rename visibility | first event appeared about **600 ms** after whole-file replacement, below the 20 s bound |
-| Cardinality | exactly **one** inbox event for the transition |
-| Equal rewrite | still exactly one event after the second, byte-identical replacement and a 2 s wait |
-| Event semantics | stream `resync`, key `goal`, subject `resource goal changed`, producer `e2eresync.cos/resync`; old/new SHA-256 values matched the actual files |
-| Teardown | supervisor exited cleanly; `st2 down` reported one torn-down agent; no scratch child remained |
-| Replay | second fresh run produced byte-identical event content and the same deterministic event id |
-
-The emitted record in both runs was:
-
-```text
----
-from: e2eresync.cos/resync
-subject: resource goal changed
-stream: resync
-event-id: 567fdb37ca198bb3cb495854eb3f8ea98bde0342948b2c0cbc3c6524febebada
-key: goal
----
-resource `goal` changed
-
-binding: goal
-path: /tmp/resync-real-e2e/net/agents/e2eresync/cos/resources/goal.md
-old: b337c4feb516944eee1f133cc2e392f631bed00ae4a426561d1f139b9ce4daec
-new: 8533e115be1140f2f303fd1c257474ad5ad8b4a787b814252d4f7f65a717faad
-```
-
-The identical event id across runs is expected: both began from the same seeded
-old digest and transitioned to the same new digest, so transition identity was
-recomputed from the same inputs. The equal rewrite produced no transition and
-therefore no second record.
-
-## Production-safety deviation
-
-The first attempt used execution host label `dev3`, matching the real
-declaration literally. It exposed a safety hazard unrelated to Resource Profile
-resolution: st2 exec/PTY runner state is keyed by host in a shared
-`$XDG_STATE_HOME/st2/<host>/exec` directory, not by catalog. The scratch
-supervisor therefore **adopted existing production runtime entries** whose task
-IDs matched the live `dev3.cos` seat. A subsequent scratch `st2 down` could have
-terminated that production seat.
-
-The attempt was stopped before reconcile mutated anything; the existing live
-seat remained untouched. The experiment was rebuilt under isolated execution
-host label `e2eresync`, giving it a fresh exec-state directory and PTY namespace,
-while preserving the production-shaped Resource URI
-`dev.schickling.agent-goal://dev3/cos` and every other declaration element.
-This is a deliberate safety deviation, not a weakening of the resolver proof:
-the profile contract uses the URI scheme and the local agent directory, not the
-execution host label, and the full resolver/watch/event path still ran.
-
-The host-state collision was recorded through the agent-feedback path during
-the experiment so future scratch-catalog work can fail closed before adoption.
-
-## Conclusion
-
-The wasm-only Resource Profile composes with the real dotfiles standing-seat
-shape end to end. A scheme URI gained a contained local denotation, rename-style
-activation remained observable through the parent-directory watch, exactly one
-deterministic event arrived, and an equal rewrite stayed silent in two fresh
-runs. The one deviation protected production runtime state and did not alter
-the Resource Profile input or behavior under test.
-
-## VRS Impact
-
-Supports [`PROFILE-R03..R09`](../requirements.md), especially feature-mode
-catalog parsing, profile-to-resync class handoff, contained local resolution,
-and nondisruptive event composition. It also supplies real-runtime evidence for
-[`06-resync`](../../06-resync/requirements.md) rename observation, seeded
-baselines, event delivery, and equal-byte suppression. The shared host runner-
-state hazard is operational feedback outside the Resource Profile contract.

-# Resource Profile plugin-boundary comparison
-
-## Question
-
-Which Resource Profile boundary gives st2 one reliable, performant extension
-mechanism while absorbing complexity in the foundation rather than repeating it
-for every downstream consumer: declarative templates, out-of-process exec
-plugins, or sandboxed wasm modules?
-
-## Common workload
-
-All three prototypes began at the same injectable exact-scheme registry seam and
-implemented the same logical profile:
-
-```text
-dev.schickling.agent-goal://<host>/<identity>
-    -> <agent-dir>/resources/goal.md
-    -> notification class immediate
-```
-
-Measurements ran on the same Linux 6.18 host with an AMD Ryzen 9 7950X3D.
-Release-mode wall time came from `std::time::Instant`; the OS page cache remained
-warm. “Cold” therefore means no process-local resolver cache or wasm instance,
-not a machine after reboot. Results compare boundary overhead, not remote I/O.
-
-## Method
-
-### Declarative template
-
-The prototype hardened the likely shipping declaration:
-
-```kdl
-profile "dev.schickling.agent-goal" {
-  carrier "{agent_dir}/resources/{file}"
-  class "immediate"
-}
-```
-
-It implemented four placeholders (`{host}`, `{identity}`, `{agent_dir}`, and
-`{file}`), strict unknown/ambiguous placeholder checks, duplicate-scheme
-rejection, component-level normalization, and an agent-directory depth floor.
-The benchmark command was:
-
-```text
-nix develop -c cargo run --release -p agent-spec --example profile_bench
-```
-
-Each workload ran 1,000 operations for five rounds; the median round was
-reported. Warm resolution reused one registry containing six schemes and
-rotated through a small URI set. Cold resolution rebuilt the registry and
-performed its first lookup for every operation. Separate loops measured a
-hostile traversal rejection and an unregistered-scheme miss.
-
-### Out-of-process exec
-
-An `ExecResolver` invoked `<executable> <uri>` with `cwd=agent_dir`, read one
-JSON line (`{"path": ..., "class": ...}`), and cached successful results by
-URI with a configurable TTL (default five seconds). Bash and compiled Rust
-plugins implemented the same protocol. The benchmark command was:
-
-```text
-nix develop -c cargo run --release -p agent-spec --example bench-exec \
-  -- 1000 <goal-resolver.sh> <goal-resolver-rs>
-```
-
-Warm mode used one resolver with a one-hour TTL after warm-up, so all measured
-calls were cache hits and spawned no process. Cold mode constructed a fresh
-resolver for every call, causing exactly 1,000 process spawns per plugin.
-Percentiles are over the 1,000 sorted per-call wall-time samples. Spawn and call
-cost were not split: each plugin only prints one short JSON document, so cold
-cost is predominantly fork/exec, interpreter or binary startup, pipe read, and
-reap.
-
-Failure-isolation tests used plugins that exited 1, slept for 60 seconds behind
-a 150 ms resolver timeout, emitted invalid/truncated/empty/oversized output, or
-aborted after a partial write. Failures were not cached; each test invoked a
-healthy resolution afterward to prove recovery in the same host process.
-
-### Wasm
-
-A core-wasm `WasmResolver` compiled one module, instantiated a fresh store and
-instance per cold resolution, and also exposed a warm loop over one live
-instance. The guest exported `memory`, `alloc`, and `resolve`, imported nothing,
-and returned packed pointer/length JSON. The command was:
-
-```text
-nix develop -c cargo run --release -p agent-spec --example wasm_bench
-```
-
-Each mode ran 1,000 resolutions; percentiles are per-call wall times. Module
-compilation and instance construction were measured separately. Two consecutive
-runs agreed within about 10 percent. The isolation suite contained 12 tests for
-normal registry composition and hostile modules: explicit traps, stack/memory
-faults, infinite loops exhausted by fuel, missing exports, garbage/invalid
-pointer returns, agent-directory escape, and oversized allocations under the
-memory limiter.
-
-Dependency cost was measured by Cargo.lock package-name set difference, binary
-byte size before/after the feature build, and `cargo build --release --timings`
-with a wiped target. Per-unit timing totals provide serial-equivalent work; wall
-clock on the 32-thread host would hide parallel compilation.
-
-## Result
-
-### Latency
-
-| Boundary and mode | p50 | p95 | p99 | max | Per-call external spawn |
-| --- | ---: | ---: | ---: | ---: | ---: |
-| Declarative warm | **0.624 µs** | — | — | — | 0 |
-| Declarative cold registry + resolve | **2.647 µs** | — | — | — | 0 |
-| Exec Rust warm TTL hit | **0.1–0.4 µs** | same range | same range | — | 0 |
-| Exec Rust cold | **760 µs** | 1,117 µs | 1,603 µs | 3,863 µs | 1 |
-| Exec bash warm TTL hit | **0.1–0.4 µs** | same range | same range | — | 0 |
-| Exec bash cold | **2.901 ms** | 4.024 ms | 4.941 ms | 9.788 ms | 1 |
-| Wasm warm call | **0.29 µs** | 0.33 µs | 0.51 µs | 0.68 µs | 0 |
-| Wasm cold (fresh instance + call) | **20.1 µs** | 29.0 µs | **33.8 µs** | 42.8 µs | 0 |
-| Wasm instance only | **10.2 µs** | 14.4 µs | 16.8 µs | ~720 µs scheduler outlier; otherwise ~25 µs | 0 |
-
-Compiling the wasm module once took **2.6 ms**. Fuel accounting is included in
-wasm call measurements and added roughly 0.1–0.2 µs. Wasm cold p50 was about
-38× faster than a compiled exec plugin and 145× faster than bash. Declarative
-was roughly 8× faster than wasm cold, but both are far below a resync window.
-
-Additional declarative figures were 0.524 µs for hostile traversal rejection
-and 0.021 µs for an unregistered-scheme miss.
-
-### Failure isolation
-
-| Failure | Declarative | Exec | Wasm |
-| --- | --- | --- | --- |
-| Path escapes agent directory | declaration/runtime normalization rejects | host validates returned path | host normalization rejects guest result |
-| Non-termination | not programmable | timeout kills and reaps child; supervisor recovers | fuel yields `FuelExhausted`; supervisor recovers |
-| Crash/trap | not programmable | non-zero/signal/partial output is unresolvable | typed trap is contained in the store |
-| Garbage or oversized result | strict template parser | 64 KiB stdout cap and strict JSON/class parser | checked memory range, UTF-8/JSON parse, 64 MiB memory cap |
-| State after failure | no mutable runtime | next process/cache miss is fresh | next resolution has a fresh store/instance |
-
-The exec process-isolation tests were green. The wasm isolation suite was
-**12/12 green**, including explicit trap, fuel-bounded infinite loop, garbage
-return, and oversized-allocation cases. Both programmable approaches preserved
-the supervisor; wasm did so without granting an executable ambient host access.
-
-### Complexity and audit surface
-
-| Boundary | One-time st2 cost | Recurring consumer cost | Dependency/runtime cost |
-| --- | --- | --- | --- |
-| Declarative | Placeholder grammar, template validation, containment, registry/catalog integration | one declaration per profile | negligible |
-| Exec | about **295 core LOC** for spawn, timeout, cap, parse, cache, and integration | **12–16 LOC/profile** for registry wiring plus a Bash/Rust plugin; executable packaging and security review | no new Rust runtime dependency; one process per cold call |
-| Wasm | about 355 host/seam LOC in the prototype plus one ABI and sandbox policy | demo guest: 111 Rust LOC, producing a **1,469-byte** artifact | **+71 lock packages**; binary 8,672,072 -> 25,026,152 bytes (**+16,354,080 / +188%**); **+45.7 s** serial-equivalent compile work; `lld` required for guest linking |
-
-The wasmtime cost is paid only with `wasm-resolver`; default dependency trees do
-not contain wasmtime. No-WASI core modules avoid a component/WIT toolchain and
-reduce the guest capability surface to three exports and zero imports.
-
-## Conclusion
-
-Raw speed favored templates, but a declarative tier would coexist forever with
-the programmable boundary and save only about 18 µs against wasm on a cold
-resolution. Exec supplied process isolation but was 38–145× slower cold,
-exposed ambient host execution, and moved packaging/security complexity to each
-consumer. Feature-gated wasm supplied one expressive mechanism, deterministic
-compute and memory bounds, contained all hostile cases, and remained negligible
-against resync timing.
-
-The evidence therefore supports a **wasm-only, feature-gated foundation** behind
-the chosen registry/SDK seam. The dependency and binary cost is real and is why
-the feature gate is constitutional, not optional cleanup.
-
-### Admission-key cache safety follow-up
-
-**Hypothesis:** A path-only refresh cache can reuse an externally admitted
-module for a catalog-relative declaration of the same absolute spelling,
-bypassing descriptor-relative no-follow traversal.
-
-**Method:** Resolve a module through a symlinked parent as an external profile,
-then resolve the same spelling as catalog-relative in one refresh. Separately,
-resolve one regular module under external and contained policies through
-registry clones and replace module bytes between refreshes.
-
-**Result:** `cache_normalization_does_not_change_the_path_used_for_admission`
-proves lexical normalization cannot erase filesystem-significant `..` after a
-symlink because admission still opens the declared spelling.
-`refresh_cache_cannot_reuse_external_admission_for_a_contained_module` proves
-the second resolution re-opens and rejects the symlink.
-`registry_clones_share_compilation_only_with_the_same_admission_policy` proves
-clones share one compilation within a policy and retain separate cache entries
-across policies. The existing replacement test proves a changed identity still
-invalidates its entry. The complete `wasm-resolver` Agent Spec suite passed 110
-tests.
-
-**Conclusion:** Snapshot outcomes and compiled success/failure entries require
-one key: normalized module path plus external-or-exact-confinement-root policy,
-then file identity. Path identity alone is not an authorization boundary.
-
-## VRS Impact
-
-Supports [`PROFILE-R01..R08`](../requirements.md) and the sandbox/ABI sections
-of [`spec.md`](../spec.md). It resolves Q8 and Q10 into
-[decision 0009](../../.decisions/0009-resource-profiles-use-a-feature-gated-wasm-boundary.md).
-Declarative templates and exec plugins are rejected alternatives, not deferred
-implementation tiers.

-# GitHub Resource attention-filter prototype
-
-Date: 2026-08-29
-
-## Question
-
-How much notification noise can state-based filtering remove before delivery to an agent, and which policy choices remain semantic rather than mechanical?
-
-## Method
-
-A deterministic 16-observation sequence modeled one pull request moving through CI queue and execution states, duplicate provider observations, review activity, mergeability changes, a CI rerun, and merge. Four filters consumed the same sequence:
-
-1. deliver every provider observation;
-2. deliver each change to a facet's current state;
-3. deliver changes classified as actionable, including CI success;
-4. deliver only blocking or terminal changes.
-
-The prototype counted candidate wakes. It did not call GitHub or an agent harness.
-
-## Evidence
-
-| Policy | Candidate wakes | Reduction | Delivered state classes |
-| --- | ---: | ---: | --- |
-| Raw observations | 16 | 0% | Every observation, including duplicates |
-| State changes | 14 | 12.5% | Every distinct facet transition |
-| Actionable changes | 7 | 56.25% | Review comment, CI failure/success, conflict, approval, merge |
-| Blocking or terminal changes | 4 | 75% | CI failure, conflict, approval, merge |
-
-Equal-state suppression removed only two duplicate observations. Most noise reduction came from semantic classification. The difference between seven and four wakes depended on whether CI success and a new review comment merit attention. A generic transport cannot infer that from byte changes alone.
-
-## Result
-
-State reconciliation and equal-state suppression are necessary but insufficient noise controls. A provider-aware layer must classify semantic changes before st2 applies generic coalescing, supersession, and delivery bounds. The experiment does not establish whether profile defaults alone are sufficient or whether each Resource binding needs an override.
-
-## Conclusion
-
-Provider-aware semantic classification is the load-bearing noise control. st2 should own only the mechanical coalescing, supersession, and delivery bounds that do not require provider semantics.
-
-## Limits
-
-The sequence is synthetic and intentionally small. It establishes mechanism boundaries, not production thresholds. Real GitHub event volume, agent wake behavior, and token cost remain unmeasured. CI systems with many parallel checks will amplify the difference between raw and semantic policies.
-
-## VRS Impact
-
-The Resource Profile design must separate provider-aware semantic classification from st2-owned mechanical delivery bounds. The interview must still decide whether the profile's default classification is final or whether a Resource binding can narrow or widen it.

-# Resource selector and runtime protocol prototype
-
-Date: 2026-08-29
-
-## Question
-
-Can the remaining selector-encoding and runtime-restart blockers be resolved with existing KDL, JSON, channel framing, and ownership-fencing patterns rather than introducing a KDL-to-JSON mapping or a second lifecycle model?
-
-## Method
-
-Three disposable Rust drivers used the repository's `kdl`, `serde`, and `serde_json` dependencies.
-
-The selector driver serialized normalized JSON, selected the smallest KDL raw-string hash fence that did not collide with the payload, parsed the generated Resource node with KDL 6, decoded the property as JSON, and compared the resulting value with the input. Inputs covered:
-
-- a concise GitHub topic selector;
-- a nested non-GitHub path/event selector;
-- an adversarial string containing one- and two-hash raw-string terminators.
-
-The runtime wire driver round-tripped length-bounded newline-delimited JSON shapes for `register`, `unregister`, `publish`, and `health`. Each message carried a runtime owner claim. Binding-scoped messages also carried a registration token.
-
-The ownership driver modeled runtime claims, binding registrations, publications, and restarts. It exhaustively enumerated every action sequence through depth seven over two runtime incarnations, two bindings, registration, and stale publication attempts.
-
-## Evidence
-
-All selector values round-tripped exactly. Representative canonical KDL was:
-
-```kdl
-resource "work" uri="github-pr://example/1" reason="Review." selector=#"{"topics":["ci.failure","mergeability.conflict","review.requested"]}"#
-```
-
-The adversarial JSON automatically selected a three-hash fence:
-
-```kdl
-selector=###"{"literal":"a\"#b\"##c"}"###
-```
-
-Dotfiles already has the matching generator precedent: `kdlRawStr context (builtins.toJSON value)` in `nixpkgs/st2/catalog.nix`. Normal quoted KDL strings are not viable there because `kdlStr` rejects embedded quotes and backslashes.
-
-The wire messages round-tripped as tagged JSON lines without a new framing format. The ownership model checked 335,923 sequences. A publication was accepted only when both conditions held:
-
-1. its `(incarnation, claim)` named the current runtime owner;
-2. its registration token matched the current registration for that binding.
-
-A new runtime claim cleared registrations and fenced every prior process and binding token. Shared and per-binding topology used the same model; a per-binding runtime is a shared runtime with one registration.
-
-## Result
-
-Agent Spec KDL can encode the descriptor-validated selector as one raw JSON string property. The canonical renderer must choose the smallest safe raw-string hash fence. The in-memory and JSON/TOML projections retain the normalized JSON value, not its KDL spelling.
-
-The observable runtime protocol needs only four semantic messages: `register`, `unregister`, `publish`, and `health`. Process EOF is termination. The runtime owns observation and therefore needs no host `reconcile` command. Supervisor process lifecycle owns shutdown and therefore needs no protocol `shutdown` command.
-
-Every runtime-to-host message is fenced by the current runtime owner claim. Every binding-scoped message is additionally fenced by the current registration token. This reuses the directional ownership pattern from harness state and the JSON-line framing pattern from native harness channels.
-
-## Conclusion
-
-Two complexity reductions survive the prototypes:
-
-- use raw JSON in KDL instead of inventing a generic KDL-to-JSON type system;
-- reduce the runtime protocol from six messages to four and use existing process EOF, supervision, and directional ownership rather than protocol-level shutdown, reconcile, or separate shared/per-binding reducers.
-
-## VRS Impact
-
-- Resolve DQ-P3 in favor of `selector=<raw-json-string>` with canonical minimum safe hash fencing.
-- Resolve DQ-P6's ownership and topology question with one owner claim plus per-binding registration tokens.
-- Remove `reconcile` and `shutdown` from the normative runtime protocol.
-- Specify EOF as runtime termination and supervisor lifecycle as the only shutdown authority.
-- Keep restart/backoff policy in existing task lifecycle machinery rather than the profile protocol.
-
-## Subsequent evidence
-
-Q39 retains the selector round-trip and directional-fencing findings as
-evidence, but supersedes the executable JSON-line runtime, including its
-process-EOF lifecycle, as the observable-provider mechanism. The
-[WASIp2 component and atomic publication prototypes](./2026-09-01-wasip2-component-and-atomic-publication-prototypes.md)
-proved a narrower universal envelope: one fresh Store and component invocation,
-domain-typed host capabilities, and a generation/revision/prior-digest proposal
-fence. No production path or protocol depends on the disposable runtime driver.

-# Smart Resource lifecycle state-space prototype
-
-Date: 2026-08-29
-
-## Question
-
-Can one small state model support profile defaults, validated binding selectors, atomic snapshots, thin invalidations, delivery unavailability, and one latest-state catch-up without an event ledger or per-transition backlog?
-
-## Method
-
-A disposable Rust model represented:
-
-- a descriptor with published topics and default topics;
-- a binding with an optional selector;
-- one canonical snapshot digest;
-- last-delivered digest, delivery availability, and pending relevance;
-- observations carrying a new digest and one semantic topic;
-- thin invalidation effects.
-
-The driver exhaustively enumerated every sequence through depth seven over five actions: relevant failure, non-default success, relevant conflict, delivery unavailable, and delivery available. An independent oracle tracked expected current snapshot and pending relevance after every transition. A separate case proved that a selector naming an unpublished topic fails validation.
-
-## Evidence
-
-The first model stored a `pending_digest`. Enumeration found this shortest class of counterexample:
-
-```text
-delivery unavailable
-relevant observation at digest 1
-irrelevant observation at digest 2
-```
-
-The binding retained pending digest 1 while canonical state had advanced to digest 2. Delivering digest 1 on resume would point the agent at a stale generation even though the relevance trigger remained valid.
-
-The corrected model stores only `pending_relevant_change: bool`. The current snapshot digest remains the single source of truth. If any relevant change occurred while delivery was unavailable, resume emits one invalidation for the then-current digest, including later irrelevant state changes.
-
-The corrected model exhaustively checked 97,656 action sequences. All snapshot, selector, and catch-up invariants held.
-
-## Result
-
-One compact per-binding state is sufficient:
-
-```text
-currentSnapshotDigest: Digest?
-lastDeliveredDigest: Digest?
-pendingRelevantChange: boolean
-deliverable: boolean
-```
-
-No pending digest, event backlog, provider cursor, or transition ledger is needed for st2 delivery semantics. Provider implementations may retain their own cursor when their native observation mechanism requires one.
-
-## Conclusion
-
-The state-first design becomes simpler when pending delivery is level-triggered. st2 records that relevant current state is unseen, not which historical event caused it. Resume always references the current canonical snapshot.
-
-The same lifecycle reducer is independent of shared versus per-binding runtime topology. Topology changes how observations arrive, not how a binding validates, publishes, filters, or catches up.
-
-## VRS Impact
-
-- Define one built-in Resource-update delivery path keyed by binding rather than profile-defined multiple streams.
-- Store a pending-relevance bit and current snapshot digest, not a pending event or digest.
-- Reuse existing event supersession and DING transport for thin invalidations.
-- Keep provider cursors, webhook delivery identifiers, polling intervals, and observation repair inside the profile implementation.
-- Specify shared and per-binding runtimes behind one normalized host protocol; do not duplicate delivery state machines.
-
-## Subsequent evidence
-
-Q39 preserves the topology-independent catch-up reducer but supersedes the
-shared/per-binding host-process mechanism in the original VRS impact. All
-observable providers now use one fresh-Store WASIp2 component invocation.
-Provider cursors and repair state remain outside the guest Store in host-owned
-domain capability state or explicit durable provider state. The delivery
-reducer remains independent of how those typed capabilities acquire input.

-# WASIp2 component and atomic publication prototypes
-
-Date: 2026-09-01
-
-## Question
-
-Can observable Resource providers run through one capability-safe WASIp2 Component Model envelope while the host retains validation, fencing, atomic publication, and delivery ownership?
-
-## Method
-
-Five disposable prototypes exercised independent parts of the boundary with Wasmtime 48.0.1:
-
-1. A GitHub Issue component imported one typed issue-source operation and exported one typed observation operation. The host enforced an exact HTTPS host, port, and path allowlist; denied redirects and non-allowlisted or loopback destinations before I/O; bounded headers and bodies; and applied connection and operation deadlines.
-2. A local-observation component imported one versioned, domain-typed `pty-stats` command. The host selected the executable and fixed arguments, passed no environment, used `/` as the child working directory, bounded retained stdout and stderr, enforced a deadline, and returned typed denials and failures. The guest could not supply an executable, path, environment, working directory, argument vector, or shell text.
-3. A component lifecycle benchmark compared compilation, verified AOT deserialization, fresh Store plus instance invocation, and state reuse with recorded in-process provider input.
-4. A cancellation and fencing driver exercised non-yielding guest CPU, a pending async host capability, concurrent same-prior proposals, stale generation after replacement, cancellation after guest return but before commit, and acknowledgement loss after commit.
-5. A runtime-neutral multiprocess publication model used an independent oracle to verify fenced compare-and-swap, deterministic outbox identity, process-crash boundaries, retry, and delivery catch-up.
-
-The harnesses and their local artifact paths were disposable experiment machinery. They are provenance for the results below, not production modules, cache locations, state formats, or reusable runtime scaffolding.
-
-## Evidence
-
-### Typed component and capability boundary
-
-- The real GitHub request returned HTTP 200 and committed one carrier plus one event intent. A cold second process sent the prior ETag, received HTTP 304, and committed neither a duplicate carrier nor a duplicate event.
-- The GitHub capability exposed one typed `get-issue(issue-key)` operation. It did not expose raw HTTP. The host applied a 16 KiB response-header ceiling, 64 KiB response-body ceiling, a 3 s connect deadline, a 10 s operation deadline, and redacted typed errors.
-- The real `pty stats --json` observation used one fresh Store and exactly one typed host call. Its allowlist entry selected one fixed executable and four fixed arguments. Five denied or failed observations left committed bytes unchanged.
-- Unknown tool IDs and unsupported typed argument variants failed before spawn. The child received zero environment entries, retained output was capped at 64 KiB per stream, and deadline cancellation targeted and reaped the process group.
-- Both components returned normalized proposals only. The host performed proposal validation and the only state commit.
-
-### Fresh Store and compiled-code reuse
-
-- Every measured observation received new guest memory, tables, resources, and host state. A reused Store retained guest and host state and had no complete reset contract for deadlines, cancellation, async resources, or post-trap state.
-- Cancellation verification created and dropped seven Stores. After guest interruption, host-future cancellation, stale fencing, commit cancellation, and acknowledgement-loss retry, active task and capability counts were zero.
-- The measured verified AOT disk-hit p50 was 0.482 ms, and fresh Store plus instance observation p50 was 47.751 µs for the small recorded GitHub component. These measurements establish that fresh-Store isolation is viable for this fixture; they are not a cross-provider latency promise.
-- AOT deserialization remained an unsafe native-code trust boundary. Corrupted artifacts were rejected before deserialization, and cache identity covered the component digest, Wasmtime/runtime build, target, and complete engine-compatibility hash.
-
-### Atomic proposal and delivery boundary
-
-- Concurrent observations with the same prior state produced exactly one compare-and-swap winner and one event intent. A stale generation after replacement committed nothing.
-- Cancellation after component return but before host commit committed nothing. Acknowledgement loss after commit retried idempotently and did not duplicate carrier or event intent.
-- The independent multiprocess oracle passed three runs of 30 processes. It recomputed carrier, event, and receipt identities from canonical durable bytes rather than importing the implementation.
-- A crash before atomic publication preserved the old authoritative state. A crash after publication but before acknowledgement exposed the new carrier and deterministic outbox intent; restart delivery caught up and duplicate retry converged on the same identity.
-- The filesystem experiment assumed POSIX lock exclusion, same-filesystem atomic rename visibility, file `fsync` before rename, and parent-directory `fsync` for durability. It did not establish power-loss behavior, remote-filesystem behavior, Windows behavior, or storage-controller honesty.
-
-## Result
-
-The evidence supports one production boundary:
-
-```text
-fresh Store + one WASIp2 provider component invocation
-        |
-        +-- only domain-typed host capabilities
-        |
-        v
-Unchanged | typed failure | Publication proposal
-        |
-        v
-host validates ProposalFence + Publication
-        |
-        v
-one atomic carrier + revision + deterministic outbox-intent transition
-        |
-        v
-separate idempotent delivery and catch-up
-```
-
-Compiled components and compatible host-owned AOT artifacts may be reused. Stores and instances may not. Capability implementations and atomic commit remain trusted host code; component sandboxing does not sandbox the host process or make a generic subprocess safe.
-
-## Conclusion
-
-A WASIp2 component is a suitable universal execution envelope for observable providers when its imports are narrow domain interfaces and every observation receives a fresh Store. The host must remain the sole authority for credentials, capability policy, validation, fencing, canonical digest, atomic carrier publication, deterministic outbox intent, and delivery acknowledgement.
-
-The evidence does not support WASIp3 production execution, Store pooling, generic exec, raw HTTP, arbitrary filesystem or socket access, a parallel native-provider lifecycle, or a runtime WAC graph. Each would enlarge or duplicate the proven boundary and requires its own evidence gate.
-
-## VRS Impact
-
-- The closed core-wasm resolver remains the identity-to-carrier mechanism.
-- One directly linked WASIp2 provider component envelope supersedes the trusted host-process observable runtime.
-- Each descriptor call or observation receives one fresh Store and instance.
-- `Publication` remains the observation payload and is paired with a host-owned generation, revision, and prior-digest fence.
-- One host transition commits the carrier and deterministic durable outbox intent; delivery and acknowledgement remain separate.
-- Generic host authorities, parallel provider runtimes, WASIp3 production, Store pooling, and runtime component graphs remain outside the contract until their explicit evidence gates are met.

-# Resource Profile language
-
-## Language
-
-**Resource Profile:** The downstream-owned contract registered for one exact Resource URI scheme. It may resolve a Resource to a contained carrier and may additionally make that Resource observable.
-
-**resolver:** The closed, pure core-wasm part of a Resource Profile that maps a preserved Resource URI and agent directory to a contained carrier denotation. A resolver has no provider or ambient host authority.
-
-**observable provider:** The part of a Resource Profile that reads provider state, normalizes it, and proposes a current snapshot. An observable provider is not a resolver, delivery sink, or provider action API.
-
-**provider component:** The WASIp2 Component Model artifact that implements an observable provider through the universal provider world. It receives a fresh execution context for each descriptor call and observation.
-
-**provider world:** The versioned Component Model execution envelope shared by observable providers. It defines the descriptor and observation exports and admits only reviewed domain-capability imports.
-
-**domain capability:** A typed host operation for one provider-domain action, including its authority, inputs, outputs, limits, and failure vocabulary. _Avoid_: generic command, raw HTTP, arbitrary filesystem, raw socket.
-
-**ambient authority:** Host access available without a specific typed grant for the observation being performed. Environment inheritance, caller-selected processes, raw network clients, arbitrary paths, and raw sockets are ambient authority in this subsystem.
-
-**observation:** One attempt to determine a binding's current provider state. Its result is unchanged, a typed failure, or a proposed `Publication`; it is not itself a state transition.
-
-**ProposalFence:** The host-issued expected state for one proposal: binding generation, revision, and prior carrier digest. It prevents replaced bindings and competing observations from publishing over a different current state.
-
-**generation:** The identity of the current active binding registration. Replacement or unregister/register creates a different generation.
-
-**revision:** The host-owned monotonic publication version within one binding generation.
-
-**prior digest:** The authoritative carrier digest the observation was based on. It is a compare-and-swap precondition, not a component assertion about current host state.
-
-**Publication:** The bounded provider payload proposed as canonical current state: schema identity, media type, snapshot bytes, semantic topics, and optional ordered typed facts. It carries no publication authority.
-
-**publication proposal:** A `Publication` paired by the host with the `ProposalFence` under which it was observed. The proposal is input to validation and commit, not durable current state by itself.
-
-**PublicationIntent:** The deterministic durable outbox entry derived by the host from an accepted proposal. It identifies the committed publication and retains the selected semantic envelope required for delivery and catch-up.
-
-**atomic publication:** The single host-owned transition that makes the new carrier and its publication metadata, resulting revision, and `PublicationIntent` visible together. Readers observe either the prior complete state or the successor complete state.
-
-**carrier:** The contained local snapshot through which an agent reads the Resource's current canonical bytes.
-
-**delivery:** The separate, idempotent attempt to convey a committed `PublicationIntent` through the built-in resync stream. Delivery does not determine whether publication committed.
-
-**delivery acknowledgement:** Durable evidence that the sink accepted a `PublicationIntent`. Until acknowledgement, the intent remains eligible for retry.
-
-**catch-up:** Level-triggered delivery of the latest relevant committed state after delivery was unavailable. Catch-up does not replay every provider transition.
-

-The leitwort is **propose, then commit**. Components observe and propose; only the host validates, fences, publishes, and delivers.

-# Resource Profile open questions
-
-The resolver registry, closed core-wasm resolution boundary, transactional
-ownership of catalog-relative wasm artifacts, state-first snapshot authority,
-universal WASIp2 observable-provider envelope, domain-typed capability rule,
-fresh Store per call, host-only fenced proposal commit, deterministic durable
-outbox intent, typed semantic facts, and atomic demand result are accepted and
-therefore are not open questions.
-
-The runtime-neutral proposal/publication foundation and the component executor
-are separate conformance layers with one commit contract. This separation does
-not create a native-provider alternative: publications from any source cross
-the same `ProposalFence` and host-owned transition, while observable provider
-execution conforms only through the component world.
-
-DQ-P3 is resolved by the raw JSON `selector` property and its round-trip
-prototype. DQ-P4 is resolved by treating initial readable state as a relevant
-state transition when the publication names a selected topic. DQ-P5 is resolved
-by explicit selector, snapshot, diagnostic, and typed-fact bounds plus
-domain-interface-specific request, response, concurrency, and deadline bounds.
-DQ-P6 is resolved by fresh per-call execution and
-`ProposalFence { generation, revision, prior_digest }`; the earlier
-host-process owner claim, registration token, topology, and JSON-line protocol
-are superseded mechanisms. Evidence is recorded in the
-[selector experiment](./.experiments/2026-08-29-selector-and-runtime-protocol-prototype.md)
-and the
-[WASIp2 component and atomic publication experiments](./.experiments/2026-09-01-wasip2-component-and-atomic-publication-prototypes.md).
-
-- **DQ-P1 Component compatibility.** Exact WIT world and domain-interface
-  versions make selection explicit, but old-component/new-host,
-  new-component/old-host, capability-version, and AOT-cache compatibility are
-  not yet proven across independent releases. Resolve before independently
-  released third-party components or capabilities with frozen WIT fixtures, a
-  cross-version conformance matrix, and cache-key rejection fixtures. Tracked
-  in the [spec](./spec.md#design-questions).
-- **DQ-P2 Provider observability.** The design separates component loading,
-  descriptor, selector, capability, observation, proposal validation,
-  publication, outbox, and delivery health, but has no operated-provider
-  evidence for the minimum low-noise logs, spans, metrics, freshness display,
-  or operator commands. Resolve with one GitHub provider and prove that an
-  operator can distinguish credential failure, provider outage, component
-  failure, capability denial, invalid proposal, stale fence, stale snapshot,
-  and undeliverable agent without hot-path noise.
-
-WASIp3 production execution, Store pooling, generic exec/raw
-HTTP/filesystem/socket authority, a parallel native provider framework, and
-runtime WAC graphs are deliberate exclusions rather than open implementation
-questions. Their evidence gates are normative in the
-[spec](./spec.md#deliberate-exclusions-and-evidence-gates-profile-r21r25).

-# Resource Profile requirements
-
-## Context
-
-A Resource binding keeps an RFC 3986 absolute URI as a portable, opaque
-identity under root [`R20`](../requirements.md). This subsystem defines the
-optional, operator-supplied bridge from such an identity to a local carrier
-that st2 can observe. It refines [`06-resync`](../06-resync/requirements.md)
-without moving scheme ownership into st2 or making successful resolution a
-condition of agent launch.
-
-The accepted resolver registry, closed core-wasm boundary, transactional
-ownership, and the Q39 amendment separating observable WASIp2 providers from
-resolution are recorded in
-[decision 0009](../.decisions/0009-resource-profiles-use-a-feature-gated-wasm-boundary.md).
-The state-first read-and-observe authority, atomic publication and demand
-result, typed semantic envelope, and latest-state catch-up are recorded in
-[decision 0014](../.decisions/0014-resource-profiles-are-state-first-read-and-observe-capabilities.md).
-
-## Assumptions
-
-- **PROFILE-A01 Downstream scheme ownership:** URI schemes and their semantic
-  meaning remain downstream-owned. st2 ships no built-in Resource profiles;
-  an unregistered scheme stays opaque and unwatchable.
-- **PROFILE-A02 Catalog trust:** The catalog operator chooses which resolver
-  module owns a scheme, which optional provider component implements
-  observation, which exact domain capabilities it may import, and which
-  notification class its results carry. Both wasm artifacts are untrusted
-  computation and receive no ambient host access.
-- **PROFILE-A03 Local denotation:** A successful profile resolution denotes a
-  path inside the bound agent's directory. It does not grant authority over the
-  URI, establish remote access, or change agent/task lifecycle semantics.
-- **PROFILE-A04 State-first authority:** For an observable profile, one atomic
-  current snapshot is authoritative. Notifications are invalidations, not a
-  complete event log, and no consumer may require every provider transition.
-- **PROFILE-A05 Downstream observation semantics:** A profile implementation
-  owns provider reconciliation, normalization, semantic topics, typed-fact
-  meaning, snapshot schema, selector defaults, and the authentication
-  requirements of its domain capabilities. The host owns credential material,
-  capability policy, generic lifecycle, validation, atomic publication and
-  demand result, coalescing, fencing, delivery, health, and containment.
-- **PROFILE-A06 Read-and-observe scope:** Read and observe do not mutate
-  provider state or standardize actions. Comments, CI reruns, label changes,
-  close, merge, approval, and other provider writes require a separate
-  authority, approval, idempotency, audit, and result-delivery design.
-
-## Acceptable Tradeoffs
-
-- **PROFILE-T01 Feature-gated runtime weight:** Wasmtime's dependency, binary,
-  and compile-time cost is accepted in builds that enable `wasm-resolver` so
-  the sandbox complexity is absorbed once. Default builds retain the baseline
-  dependency and binary surface.
-- **PROFILE-T02 Two typed wasm contracts:** st2 owns the closed core-wasm
-  resolver ABI and the versioned WASIp2 Component Model provider world. The
-  resolver remains deliberately smaller because it only maps identity to a
-  contained carrier; observable providers use the richer component type
-  system without gaining ambient authority.
-- **PROFILE-T03 Fresh observation state:** Compiled resolver modules and
-  provider components may be cached, but each resolution, descriptor call, and
-  provider observation receives a fresh Store and instance. The instantiation
-  cost is accepted so guest memory, tables, resources, host state, fuel,
-  deadlines, cancellations, and traps cannot leak between calls.
-- **PROFILE-T04 Superset-biased leaf publication:** Whole-catalog apply may
-  leave an unreferenced new wasm artifact after a crash. Ordered atomic leaf
-  publication is preferred over a multi-file swap because catalog readers are
-  already fenced by the transaction marker and recovery can remove the
-  harmless superset; the catalog declaration must never point to a missing new
-  catalog-owned artifact.
-- **PROFILE-T05 Provider-domain capabilities:** st2 hosts explicit typed
-  provider capabilities rather than generic process, network, or filesystem
-  access. Adding a provider domain therefore requires a reviewed host
-  interface, but its authority, validation, limits, and errors remain visible
-  in the type boundary.
-- **PROFILE-T06 One snapshot rather than facets:** The contract rewrites one
-  atomic profile-defined snapshot even when provider facets change
-  independently. This avoids generation manifests, facet consistency, and
-  retention machinery until measured payload or read costs justify them.
-- **PROFILE-T07 Schema execution:** Discovering profile capabilities, selector
-  vocabulary, defaults, and validation requires instantiating the same bounded
-  component selected by the catalog. This keeps the contract and
-  implementation atomic at the cost of making descriptor execution part of
-  validation.
-- **PROFILE-T08 One component per observation:** A provider runs as one
-  directly linked component invocation, not a long-lived process or runtime
-  composition graph. Provider-native caches, cursors, and webhook repair state
-  therefore live in host-owned domain capability state or durable provider
-  state rather than guest Store state.
-
-## Requirements
-
-### Must provide one principled extension boundary
-
-- **PROFILE-R01 Resolver SDK contract:** The reusable `agent-spec` library
-  exposes one typed resolution contract: an exact URI scheme selects a
-  resolver, and resolution takes the preserved URI plus the agent directory and
-  returns either a contained local path with a notification class or a
-  structured failure. The registry is injectable so catalogs can add or
-  replace profiles without hard-coding downstream schemes into st2.
-- **PROFILE-R02 Wasm-only profile mechanisms:** Every declared Resource profile
-  names one closed core-wasm resolver module. A profile that declares observable
-  capabilities additionally names one WASIp2 Component Model provider.
-  Declarative path-template, host-exec, native-provider, and alternate runtime
-  tiers are not part of the boundary; static mapping uses the resolver and all
-  observable behavior uses the component envelope.
-- **PROFILE-R03 Exact, deny-by-default registry:** Lookup is by an exact RFC
-  3986 scheme beginning with an ASCII letter. Duplicate declarations, malformed
-  declarations, unknown profile fields, and unsupported notification classes
-  fail validation. Missing profiles do not fall back to guessed semantics.
-
-### Must contain resolver behavior
-
-- **PROFILE-R04 Closed sandbox:** Resolver modules run with no WASI and no host
-  imports. Module files are opened nonblocking and accepted only as regular
-  files, under a finite module-byte admission bound, per-call fuel budget,
-  linear-memory cap, and table-element cap. Traps, infinite loops, missing
-  exports, invalid memory ranges, malformed output, and special or oversized
-  module, table, or allocation attempts cannot unwind into or terminate the
-  supervisor.
-- **PROFILE-R05 Host-enforced path boundary:** A module's non-empty returned
-  path is decoded and normalized by the host and accepted only when it remains
-  inside the agent directory. Every root, ancestor, and final component is
-  opened without following symlinks; only regular final files are read.
-  Guest-chosen paths never bypass host containment or block the worker on a
-  special file.
-- **PROFILE-R06 Failure is local and observable:** An unregistered scheme is an
-  ordinary opaque binding. A registered profile that cannot load or resolve is
-  distinguishable from a miss through the SDK, reported by reconciliation,
-  degrades only that binding to unwatchable, and leaves the resident supervisor
-  and unrelated profiles alive.
-
-### Must preserve optionality and composition
-
-- **PROFILE-R07 Feature isolation:** `wasm-resolver` is an opt-in build feature
-  covering both the resolver engine and observable component executor. A
-  default build carries no wasmtime dependency. It can still parse and retain
-  profile declarations, but attempting to resolve or observe one reports that
-  the feature is unavailable rather than silently substituting another
-  mechanism.
-- **PROFILE-R08 Resync composition:** Successful resolution supplies both the
-  local carrier path and its declared `immediate` or `coalesced` class to
-  resync. Profile class takes precedence over basename heuristics; `silent`
-  carriers are excluded before resolver execution. Watching, digest
-  deduplication, event identity, and delivery otherwise remain the
-  [`06-resync`](../06-resync/requirements.md) contract.
-- **PROFILE-R09 Nondisruptive bindings:** Adding, removing, changing, or failing
-  a Resource profile does not make URI possession authoritative and does not
-  change task launch targets. Resource-only declaration changes preserve root
-  [`R21`](../requirements.md): healthy work is adopted without stop,
-  replacement, or relaunch.
-
-### Must transact catalog-owned modules
-
-- **PROFILE-R10 Transactional wasm ownership:** A resolver module or provider
-  component whose declared path is catalog-relative is a first-class
-  declaration input. Snapshot, digest, diff, bootstrap, prepare, apply, and
-  recovery include its exact normalized path and bytes in the catalog
-  projection and root hash. Duplicate references to one normalized path
-  contribute one input. A missing, escaping, symlinked, special, oversized, or
-  unprojected catalog-owned artifact fails validation before publication.
-  Literal absolute paths remain external immutable inputs and are not copied
-  into catalog bundles. Publication orders new artifact bytes before the
-  `catalog.kdl` that names them and retires old artifact bytes only after that
-  declaration stops naming them.
-
-### Must opt into chain notification
-
-- **PROFILE-R11 Explicit chain notification:** A profile may opt into
-  supervisor-chain notification. For a binding through that profile, resync
-  includes active same-scheme carriers from every non-retired supervisor
-  ancestor in the descendant's watch set. The flag is false by default, does
-  not change path containment or task launch, and an invalid supervisor chain
-  is reported rather than silently approximated.
-
-### Must describe and validate observable capabilities
-
-- **PROFILE-R12 Versioned component descriptor:** An observable provider
-  exposes one bounded, typed descriptor through the universal WASIp2 provider
-  world. It declares capabilities, selector schema, semantic topic vocabulary,
-  default selector value, snapshot media type, and snapshot schema identity.
-  The host validates the descriptor under the same fresh-Store, resource-bound,
-  no-ambient-authority, and failure-isolation policy as observation. Unknown
-  required capabilities or provider-world versions fail that profile locally.
-- **PROFILE-R13 Validated binding selectors:** An observable Resource binding
-  may carry profile-specific selector configuration. Absence means the
-  descriptor's default. KDL encodes the value as compact JSON in a `selector`
-  raw-string property whose canonical renderer chooses the smallest safe hash
-  fence; JSON and TOML forms carry a native JSON value. All forms lower to one
-  normalized value that st2 validates against the descriptor before activating
-  observation. A selector may choose only profile-published topics; it changes
-  attention, never Resource URI identity, access authority, snapshot contents,
-  or provider observation.
-
-### Must commit one fenced proposal atomically
-
-- **PROFILE-R14 Atomic proposal authority:** Each active observable binding has
-  at most one profile-defined canonical current snapshot. A component may
-  return `Unchanged`, a typed failure, or one complete `Publication`. For a
-  publication result the host constructs a proposal from that payload and the
-  invocation's `ProposalFence { generation, revision, prior_digest }`, validates
-  it, and alone owns the commit. One atomic transition makes the carrier,
-  current digest, resulting revision, freshness, semantic catch-up state, and
-  deterministic durable `PublicationIntent` visible together; the component
-  cannot write any of them. Equal accepted bytes do not create a state
-  transition. A crash before publication leaves the prior state authoritative.
-  A crash after publication but before delivery acknowledgement leaves the
-  outbox intent retryable.
-- **PROFILE-R15 Domain-typed observation:** Every observable provider executes
-  through the same versioned WASIp2 Component Model envelope and may import
-  only host-linked, provider-domain capabilities explicitly declared for that
-  component. Host implementations own credentials, endpoint and operation
-  allowlists, response and concurrency bounds, deadlines, cancellation, and
-  redacted typed errors. The component owns provider normalization and may
-  propose canonical state; it receives no ambient WASI command, environment,
-  clock, random, process, raw HTTP, filesystem, or socket authority.
-- **PROFILE-R16 Fresh-Store execution and fencing:** Every descriptor call and
-  observation creates a fresh Store and component instance, invokes it once,
-  validates the result, and drops the Store. The host may reuse an Engine,
-  Linker, and compiled component keyed by exact artifact and engine
-  compatibility, but never pools or resets Store or instance state. Every
-  proposal is fenced by the current binding generation, expected revision, and
-  prior carrier digest. The host rejects stale generation or stale prior state
-  without publication; concurrent proposals from one prior state have at most
-  one commit winner, and retry of the same deterministic proposal is
-  idempotent.
-- **PROFILE-R16A Finite execution and proposal bounds:** A selector's canonical
-  compact JSON is at most 16 KiB. Decoded snapshot bytes are at most 1 MiB.
-  Health detail and a failed observation diagnostic are each at most 16 KiB of
-  UTF-8. One `Publication` carries at most 32 ordered facts; each fact key is at
-  most 128 bytes and each before/after value is at most 1 KiB of printable
-  single-line UTF-8. Each domain capability defines request, response,
-  concurrency, and deadline bounds before it is linked. st2 rejects an
-  oversized or invalid value without truncation and contains the failure to
-  the affected observation or binding.
-- **PROFILE-R16B Declared atomic demand:** Demand observation is explicitly
-  declared and denied by default. Only a component descriptor with the
-  `demand` capability may receive a demand invocation. Each invocation carries
-  a positive demand watermark and a
-  `ProposalFence { generation, revision, prior_digest }`. It returns exactly
-  once with `Unchanged`; a bounded typed failure; or one `Publication`. There
-  is no separate publication and settlement, digest supplied as authority by
-  the component, or protocol observation timestamp.
-- **PROFILE-R16C Coalesced, non-cancelling demand:** For one active binding
-  generation, st2 keeps at most one demand invocation in flight and one latest
-  trailing watermark. Demand accepted during an in-flight observation survives
-  its result and coalesces into the trailing invocation. Only an exact atomic
-  result, replacement of its fenced generation, or executor failure closes
-  accepted work; no clock participates in correctness. `Committed` settles as
-  `settledChanged` with the host-computed accepted-publication digest, including
-  when resync delivery fails after the carrier and outbox intent commit;
-  proposal-commit `Unchanged` settles as `settledUnchanged`. A missing active
-  binding or one without demand maps to `absentBinding`; an older client
-  generation maps to `staleGeneration`; a newer generation remains queued
-  until supervisor refresh; provider failure maps to `providerUnavailable`.
-  Client disconnect or wait expiry does not cancel accepted work, retract it,
-  or alter observation scheduling.
-- **PROFILE-R16D Durable demand intent:** Observe request and receipt records
-  carry the exact schema identities `st2.resource-observe-request.v1` and
-  `st2.resource-observe-receipt.v1`. They are private to one supervisor scope
-  and bounded to 64 KiB each. Durable admission permits at most 256 unresolved
-  requests per scope; an attempt beyond that cap receives submission
-  backpressure before it is admitted, and request scanning remains bounded by
-  the same cap. An admitted request record remains the durable, retryable
-  intent until a terminal receipt is durably committed; only then may the
-  request be removed. In-memory enqueue and nonterminal receipts do not
-  transfer that ownership. A failed terminal receipt commit retains retryable
-  state and leaves the request eligible for restart. Receipt status values use
-  camelCase: `accepted` and `backpressured` are nonterminal;
-  `settledUnchanged`, `settledChanged`, `settledFailed`, `absentBinding`,
-  `staleGeneration`, and `providerUnavailable` are terminal. Only
-  `settledChanged` carries the host-computed digest of accepted publication
-  bytes. Provider diagnostics normalize to an optional bounded receipt value.
-
-### Must bound attention and catch up to current state
-
-- **PROFILE-R17 Semantic invalidation:** Every Resource invalidation carries the
-  same bounded ordered fact envelope in its durable body and renders at most
-  three whole facts into a subject of at most 96 Unicode scalars. For a
-  published result, the host validates facts and topics, applies the binding
-  selector, and derives the deterministic `PublicationIntent` committed with
-  the carrier. Passive carrier changes publish one `content` topic and a short
-  digest-transition fact. Agent Spec declaration changes publish ordered
-  binding-label facts for added, removed, and semantically changed Resource
-  declarations without exposing URIs or reasons; unavailable declaration
-  parsing falls back to a digest-transition fact rather than dropping the
-  invalidation. Snapshot bytes and provider payloads remain in the
-  authoritative carrier, not the event.
-- **PROFILE-R18 Built-in superseding delivery:** Smart Resource invalidations
-  reuse one built-in per-agent delivery stream and the existing inbox, DING,
-  deduplication, and producer-side supersession machinery. The binding name is
-  the supersession key. Profiles do not create one stream per topic or a third
-  delivery plane.
-- **PROFILE-R19 Level-triggered catch-up:** Snapshot reconciliation continues
-  while delivery is unavailable. Per binding, st2 retains the current snapshot
-  digest, the last-delivered digest, one pending-relevance condition, and the
-  latest relevant selected topics and facts, not a transition backlog or
-  pending historical digest. When delivery becomes available, pending relevant
-  state emits at most one invalidation for the then-current snapshot digest
-  with that retained semantic envelope.
-- **PROFILE-R20 Observable health:** st2 reports component loading, descriptor,
-  selector, capability, observation, proposal validation, publication, and
-  delivery health separately. Failure degrades only the affected profile or
-  binding, preserves the last proven snapshot with explicit freshness, and
-  never presents stale bytes as newly observed state.
-
-### Must keep the component authority narrow
-
-- **PROFILE-R21 WASIp2 production baseline:** Observable providers target the
-  WASIp2 Component Model. WASIp3 production execution is not part of this
-  contract.
-- **PROFILE-R22 No Store pooling:** Provider Stores and instances are never
-  pooled, reused, or reset across observations.
-- **PROFILE-R23 No generic host escape hatches:** The provider world exposes no
-  caller-selected executable or arguments, shell, raw HTTP client, arbitrary
-  filesystem path, or raw socket capability. Domain interfaces are not thin
-  aliases for those authorities.
-- **PROFILE-R24 One provider framework:** st2 does not maintain a parallel
-  native or host-process provider framework. Observable profiles use the
-  component envelope.
-- **PROFILE-R25 No runtime component graph:** The host links one provider
-  component directly to reviewed domain capabilities. Runtime WAC composition
-  and provider-selected component graphs are not part of execution.

-# Resource Profile spec
-
-This document specifies the Resource Profile registry, closed core-wasm
-resolver, universal WASIp2 observable-provider envelope, and state-first
-atomic publication authority. It builds on
-[`requirements.md`](./requirements.md).
-
-## Status
-
-Draft. The runtime-neutral fenced proposal, atomic publication, and durable
-outbox contract is the foundation shared by passive and component-produced
-publications. Component-enabled conformance additionally requires the execution
-and capability boundary below; a native runtime is not a fallback.
-
-## Ownership and flow
-
-This subsystem owns scheme-to-profile registration, both guest ABIs, descriptor
-and selector validation, sandbox budgets, host path containment, provider
-component lifecycle, host-only atomic proposal commit, and the handoff of
-passive and observable carriers to [`06-resync`](../06-resync/spec.md). It does
-not own Resource URI semantics, provider credentials, provider mutation, task
-launch, a canonical provider event log, or ambient host access. Those remain
-downstream semantics or explicit non-goals.
-
-## Architecture (PROFILE-R01..R25)
-
-Resolution remains a closed core-wasm operation:
-
-```text
-Agent Spec resource URI (opaque, byte-preserved)
-             |
-             v exact RFC 3986 scheme
-<catalog>/catalog.kdl
-  profile "<scheme>" { wasm "<resolver>"; class "<class>"; ... }
-             |
-             +--> catalog-relative resolver -- normalized no-follow projection
-             |                                + catalog root hash / transaction
-             |
-             v ResourceProfileRegistry (injectable; built-ins empty)
-      bounded compiled-module cache
-             |
-             v fresh Store + Instance per resolution
-   closed core-wasm guest (no imports / no WASI)
-             |
-             v UTF-8 JSON path -> host lexical containment
-      Resolution { path, containment_root, declared ProfileClass }
-             |
-             v descriptor-relative, no-follow digest reads
-      resync watch set and existing event pipeline
-```
-
-An observable profile adds one component artifact; it does not replace or
-enlarge the resolver:
-
-```text
-WASIp2 provider component
-  export describe()
-  export observe(request)
-  import only reviewed domain capability interfaces
-             |
-             v fresh Store + Instance for one call
-Unchanged | typed failure | Publication
-             |
-             v host pairs Publication with ProposalFence
-validate generation + revision + prior digest + payload bounds
-             |
-             v one host-owned atomic transition
-carrier + current digest/revision + freshness/catch-up + PublicationIntent
-             |
-             v separate idempotent delivery from durable outbox
-built-in resync event (key=binding, supersede=true)
-             |
-             v existing inbox + DING
-agent rereads canonical carrier
-```
-
-The SDK is a typed, trait-shaped boundary rather than a set of scheme-specific
-branches. Its concrete public surface is `ResourceProfile`, `ProfileSource`,
-`ResourceProfileRegistry`, `Resolution`, `WasmResolver`, `WasmInstance`, and
-`WasmResolveError`. The registry expresses the resolver contract as:
-
-```rust
-fn try_resolve(
-    &self,
-    agent_dir: &Path,
-    uri: &str,
-) -> Result<Option<Resolution>, String>;
-```
-
-`Ok(None)` means no syntactically valid scheme or no exact registration.
-`Ok(Some(_))` is a contained local denotation, its enforced read root, and the
-catalog-declared class. `Err(_)` means the scheme was registered but its wasm
-implementation was unavailable or failed. `resolve` is the containment-oriented
-convenience API that folds the final case into unwatchable; callers needing
-diagnostics use `try_resolve`.
-
-There is one source variant:
-
-```rust
-ProfileSource::Wasm {
-    module: PathBuf,
-    class: ProfileClass,
-    containment_root: Option<PathBuf>,
-}
-```
-
-`containment_root` is the trusted descriptor-traversal root for
-catalog-relative resolver modules and is absent for explicitly external
-absolute modules. Observable component configuration is separate from
-`ProfileSource`: it cannot participate in path resolution or change
-`ProfileClass`.
-
-There is no template or exec variant. `ResourceProfileRegistry::builtin()` is
-empty. `with_profile` and `with_profiles` inject catalog-owned registrations;
-a later programmatic insertion for the same exact scheme replaces the prior
-entry, while duplicate schemes in one catalog declaration are rejected before
-registry construction. Observable execution is present only when the same
-profile also declares one component and its exact allowed WIT capability
-interfaces.
-
-## Catalog declaration (PROFILE-R02..R03)
-
-Profiles are top-level `catalog.kdl` nodes, siblings of the optional `catalog`
-block:
-
-```kdl
-catalog {
-  pty-root "pty"
-}
-
-profile "dev.schickling.agent-goal" {
-  wasm "resolvers/agent-goal.wasm"
-  class "immediate"
-  notify-chain #true
-}
-
-profile "github-issue" {
-  wasm "resolvers/github-issue.wasm"
-  component "providers/github-issue.component.wasm"
-  capability "st2:github-issue/source@1.0.0"
-  class "coalesced"
-}
-```
-
-Grammar:
-
-```text
-profile <non-empty-scheme> {        # exactly one positional value; no properties
-  wasm <non-empty-path>              # exactly once; closed resolver
-  component <non-empty-path>         # zero or one; observable provider
-  capability <wit-interface-id>      # zero or more; requires component
-  class immediate|coalesced|silent  # zero or one; default coalesced
-  notify-chain <boolean>             # zero or one; default false
-}
-```
-
-The profile scheme follows RFC 3986: it begins with an ASCII letter, then
-accepts ASCII alphanumeric characters plus `+`, `-`, and `.`, and rejects `/`;
-lookup remains exact and case-sensitive. The profile node takes exactly one
-quoted positional scheme and no properties. `wasm`, `component`, and `class`
-each take one quoted positional value; `notify-chain` takes one boolean and
-each `capability` takes one exact versioned WIT interface ID. Capability IDs
-are owned by their WIT package namespace; the host compares the canonical
-package, interface, and complete semantic version, not a display alias.
-Duplicate capability IDs, capability without component, unknown or extra
-entries, duplicate singleton children, missing `wasm`, unsupported class
-values, and duplicate profile schemes fail parsing.
-
-A literal absolute wasm artifact path remains an external runtime input. Every
-other resolver or component declaration expands `$CATALOG` and environment
-variables, resolves lexically against the catalog root, and must remain
-strictly beneath that root; internal `.`/`..` components normalize away, while
-traversal outside the root fails validation.
-
-`st2 validate` reports malformed declarations, missing or unsafe
-catalog-relative artifacts, provider-world mismatches, and component imports
-outside the profile's exact capability set. `st2 up` loads declared profiles
-before it spawns tasks, so an invalid profile fails loudly rather than silently
-removing watch or observation coverage.
-
-The scheme namespace remains downstream-owned. A private profile uses its
-owner's reverse-domain scheme (for example `dev.schickling.agent-goal`); st2
-registers no public scheme and assigns no semantics to the URI authority or
-path. Representative behavior:
-
-| Input | Registration | Result |
-| --- | --- | --- |
-| `dev.schickling.agent-goal://dev3/cos` | exact profile declared | invoke that module |
-| `worktree://repo/main` | none | opaque and unwatchable |
-| `resources/goal.md` | no URI scheme | profile registry miss; resync's local-path rule applies |
-| `file:///tmp/x` | none | profile registry miss; resync's `file://` rule applies |
-| `dev.schickling.agent-goal://x` with broken module | exact profile declared | registered-profile failure; no fallback |
-
-## Catalog transaction projection (PROFILE-R10)
-
-```text
-exact root catalog.kdl
-          |
-          v parse + expand each non-absolute wasm/component path
-lexically normalized path strictly below catalog root
-          |
-          v descriptor-relative O_NOFOLLOW open
-regular bounded artifact
-          |
-          v deduplicate by normalized relative path
-catalog transaction projection + declaration-root hash
-          |
-          v snapshot / digest / diff / bootstrap / apply / recovery
-prepared bundle and live catalog contain the same declaration + artifact bytes
-```
-
-The whole-catalog projector parses only the exact `catalog.kdl` at its
-projection root. Each catalog-relative resolver module and provider component
-is opened from a retained root capability: every ancestor is a no-follow
-directory and the final no-follow, nonblocking descriptor must be a regular
-file within its admission bound. Missing files, symlinked ancestors or leaves,
-FIFOs and other special files, paths escaping the root, and oversized artifacts
-reject the transaction and `st2 validate`. References whose paths normalize to
-the same relative path contribute one projected entry. Any file present in a
-prepared catalog but absent from this closed projection remains an
-unprojected-input error.
-
-A literal absolute `wasm` or `component` path is external and immutable from
-the catalog transaction's perspective. Its bytes are neither copied nor hashed,
-even when the literal happens to name a file physically below the live catalog.
-A non-absolute declaration that expands through `$CATALOG` or an environment
-variable is catalog-owned and must still normalize beneath the logical catalog
-root; expansion cannot turn a relative declaration into an escape hatch.
-
-Apply publishes new or changed projected inputs before atomically replacing
-`catalog.kdl`, then removes stale projected inputs after the declaration no
-longer names them. The incomplete-apply marker fences cooperating catalog
-readers throughout this sequence. The crash bias is a safe superset: failure
-before declaration replacement may leave an unreferenced new artifact, and
-failure after it may leave an unreferenced old artifact, but live `catalog.kdl`
-never names a missing newly published artifact. Durable-stage recovery repeats
-the same ordering and removes the superset.
-
-## Core wasm ABI (PROFILE-R04..R05)
-
-The resolver is a core wasm module, not a WASI program or component. It imports
-nothing and exports exactly the functions/memory the host calls:
-
-```text
-memory
-alloc(len: i32) -> i32
-resolve(uri_ptr: i32, uri_len: i32,
-        dir_ptr: i32, dir_len: i32) -> i64
-```
-
-The host copies the preserved URI and the UTF-8 agent-directory path into guest
-linear memory through `alloc`. `resolve` returns a packed unsigned
-`(ptr << 32) | len`. The selected bytes must be UTF-8 JSON:
-
-```json
-{"path":"resources/goal.md","class":"goal"}
-```
-
-`path` is required and non-empty. `class` is an optional, free-form guest
-classification and is not the resync notification class: notification policy
-comes only from the trusted catalog declaration's `ProfileClass`. This prevents
-an untrusted guest from escalating a `silent` profile to `immediate`.
-
-Before reading or acting, the host checks allocator pointers and the returned
-pointer/length range against linear memory, parses UTF-8 and JSON, rejects an
-empty path, joins the returned path to `agent_dir`, and lexically normalizes
-`.`/`..`. A result equal to or outside `agent_dir`, or one crossing an existing
-symlink below it, is rejected; a resolver must denote a carrier beneath the
-root rather than the confinement root itself. Existence is not required at
-resolution time; the carrier may be created later.
-
-Successful resolution carries the normalized agent-directory root into resync.
-Every later digest read opens that root and then each relative component with
-no-follow semantics, using each directory descriptor for the next lookup, and
-reads the already-open final descriptor. A root, ancestor, or final component
-replaced by a symlink before or during traversal fails closed; admission-time
-metadata alone is never treated as a durable proof.
-
-## Runtime containment (PROFILE-R04..R07)
-
-Each module is opened nonblocking and no-follow, accepted only as a regular
-file, and read through a 16 MiB admission cap before validation or compilation.
-Catalog-relative modules are traversed descriptor-relative from the catalog
-root with `O_NOFOLLOW` on every ancestor and the final component.
-The bounded 32-entry LRU cache stores both successful modules and compilation
-failures by normalized module path, admission policy, byte digest, and stable
-file metadata. Admission policy distinguishes an external open from
-descriptor-relative traversal under a specific confinement root. Lexical
-normalization is used only for cache identity; the admission read always opens
-the declared module spelling so filesystem-significant `..` after a symlink or
-missing component cannot be erased. Refresh-local snapshot outcomes use the
-same path-and-policy key, so resolving one spelling externally can never
-authorize a contained declaration. Registry clones and concurrent subscribers
-coalesce one compilation attempt only for an unchanged identity under the same
-policy. Byte replacement or metadata identity change invalidates that entry.
-Each resolution of a successfully compiled module creates a fresh `Store` and
-`Instance`. One fuel allowance covers the module start function and its single
-resolution call; the instance is then discarded.
-
-| Boundary | Contract |
-| --- | --- |
-| Module file | regular, nonblocking; catalog-relative paths use descriptor-relative no-follow traversal for every component; 16 MiB maximum before Wasmtime compilation |
-| Imports | none; import-requiring modules fail instantiation |
-| Fuel | 5,000,000 fuel units for start + the single resolution call |
-| Linear memory | 64 MiB maximum |
-| Resolver return | memory range must be valid and at most 64 KiB before UTF-8/JSON decoding |
-| Memories | at most 1 |
-| Tables | at most 4, with at most 10,000 elements each |
-| Instance state | fresh per registry resolution |
-| Compiled code/failure | 32-entry LRU by normalized module path + admission policy (external or exact confinement root) + byte digest + file metadata; shared across registry clones only for the same policy |
-
-Failure taxonomy:
-
-| Failure | SDK result | Supervisor effect |
-| --- | --- | --- |
-| special/oversized module or module load/instantiation | `Instantiation` | binding unwatchable; reconcile warning; supervisor lives |
-| missing `memory`, `alloc`, or `resolve` | `MissingExport` | same |
-| unreachable/stack/memory trap | `Trap` | same |
-| infinite start function or call | `FuelExhausted` | same |
-| invalid pointer, oversized return, UTF-8, JSON, empty/escaped path, symlink, or special-file read | `BadReturn` or unreadable carrier | same |
-| feature disabled | registered-profile error | same; no alternate resolver |
-
-All wasmtime code and dependencies are gated by `wasm-resolver`, forwarded from
-the root st2 crate to `agent-spec`. Without that feature the declaration and
-registry types remain available, but registered resolution reports the missing
-feature. Default binaries therefore retain the baseline dependency surface.
-Building a Rust guest for `wasm32-unknown-unknown` requires `lld`, which the
-repository dev shell supplies.
-
-## Resync composition (PROFILE-R08..R09, PROFILE-R11)
-
-For each active Resource binding, resync applies this precedence:
-
-1. A URI with a registered `silent` profile is excluded without loading or
-   executing its resolver. Any other registered profile resolves through the
-   registry. Success adds the contained path with the profile's declared
-   class. Failure leaves only that binding unwatchable and adds a reconcile
-   warning naming the agent and binding.
-2. An unregistered `file://` URI uses the existing absolute-file rule.
-3. A schemeless path uses the existing agent-directory-relative rule.
-4. Every other unregistered scheme remains opaque and unwatchable.
-
-Passive resolved carriers use the same Resource fact envelope as observable
-publications. A content transition emits topic `content` and one
-`digest=<old-short>→<new-short>` fact. Declaration subscriptions retain a
-bounded summary keyed by binding label whose values digest URI, reason,
-inactive state, and selector. On a declaration flush, one bounded catalog parse
-derives the current summary: added labels transition absent→`declared`, removed
-labels transition `declared`→absent, and changed summary digests publish
-`label=changed`, ordered by label. URIs and reasons never enter the event. A
-parse failure, unchanged Resource summary, or summary outside fact bounds falls
-back to the declaration carrier's digest transition. Parent-directory
-observation, rename replacement, digest seeding, equal-byte deduplication,
-deterministic transition identity, and bounded windows otherwise remain the
-[`06-resync`](../06-resync/spec.md) pipeline.
-
-`notify-chain #true` extends only subscription selection. For each active
-binding through that profile, resync validates the bound agent's supervisor
-chain against the complete catalog and adds every active same-scheme carrier
-declared by non-retired ancestors. Each ancestor URI is resolved unchanged
-against that ancestor's own directory and remains inside that directory's host
-containment root. Retired ancestors are skipped without severing traversal.
-Owner-qualified event keys keep layers independent. An invalid chain or failed
-ancestor resolution produces a reconcile warning; st2 never synthesizes a URI
-or silently claims complete chain coverage. The default `false` preserves the
-agent-local behavior above.
-Profile resolution is observation metadata only and never enters task launch
-targets.
-
-## Observable provider world (PROFILE-R12..R13)
-
-An observable profile retains the closed resolver and adds one component that
-conforms to the repository-owned
-`st2:resource-provider/provider@0.1.0` WASIp2 world. The package and interface
-names are lowercase ASCII WIT identifiers and the complete semantic version is
-part of compatibility. A host accepts only an exact supported world; it does
-not guess across unknown major, minor, or patch versions.
-
-The world has two host-called exports:
-
-```text
-describe() -> result<ProviderDescriptor, DescriptorError>
-
-observe(ObserveRequest {
-  uri,
-  selector,
-  prior_digest?,
-  demand_watermark?
-}) -> ObservationResult {
-  Unchanged
-  | Failed { diagnostic? }
-  | Published { publication: Publication }
-}
-
-Publication {
-  schema_id,
-  media_type,
-  bytes,
-  topics,
-  facts?
-}
-```
-
-`ProviderDescriptor` declares supported scheduling capabilities, selector
-schema, default selector, published semantic topics, snapshot media type, and
-snapshot schema identity. The typed provider world replaces descriptor ABI 3's
-packed core-wasm JSON export and the host-process JSON protocol. It does not
-replace the resolver ABI.
-
-The host calls `describe` in a fresh Store under descriptor phase policy.
-Operational domain capabilities return a typed phase denial if the component
-attempts to call them while describing itself. The descriptor is bounded and
-fully validated before any binding is activated. Unknown required
-capabilities, duplicate or empty topic names, an invalid selector schema or
-default, mismatched snapshot identity, and an unsupported world version fail
-only that profile.
-
-Agent Spec KDL carries normalized selector JSON as a `selector` raw-string
-property:
-
-```kdl
-resource "pr" uri="github-pr://github.com/example/project/pull/42" reason="Review." \
-  selector=#"{"topics":["ci.failure","review.requested"]}"#
-```
-
-The canonical renderer serializes compact normalized JSON and chooses the
-smallest raw-string hash fence whose closing delimiter does not occur in the
-payload. JSON and TOML Agent Spec forms carry the selector as a native JSON
-value. All forms lower to the same `serde_json::Value`; KDL spelling is not
-preserved. The selected value must validate against the descriptor schema and
-may name only published topics. It cannot change resolution, snapshot bytes,
-credentials, linked capabilities, or provider authority.
-
-## Component execution and capabilities (PROFILE-R15..R16A, R21..R25)
-
-```text
-host scheduler
-     |
-     v load exact catalog-selected Component
-reuse Engine + Linker + compiled Component when cache identity matches
-     |
-     v create fresh Store<ProviderHost>
-link only catalog-approved domain WIT interfaces
-     |
-     v instantiate once; describe or observe once
-     |
-     v validate typed result; cancel outstanding capability work
-drop instance + Store
-```
-
-The host creates a new `Store<ProviderHost>` and component instance for every
-descriptor call and observation. No Store, instance, guest memory, table,
-resource handle, host call counter, deadline state, fuel state, or cancellation
-state survives the call. An observation invokes `observe` exactly once.
-
-One process may retain an Engine, Linker, and compiled Component. Cache identity
-includes the exact component SHA-256, Wasmtime/runtime build identity, target
-triple, and a fingerprint of every compilation-relevant Engine setting. A
-host-produced AOT artifact is deserialized only after its length and SHA-256
-match an authenticated host-owned manifest and that complete compatibility key.
-Any mismatch is a cache miss. Guest-supplied precompiled bytes never cross the
-unsafe deserialization boundary.
-
-Provider components are WASIp2 components but are not WASI command programs.
-The Linker supplies neither `wasi:cli`, inherited environment, ambient clocks
-or random, filesystem preopens, sockets, raw HTTP, nor a caller-controlled
-process API. Every non-foundation import must:
-
-1. be an exact versioned WIT interface listed by the profile's `capability`
-   declarations;
-2. represent one provider-domain operation with typed inputs, outputs, policy
-   denials, and operational failures;
-3. keep credentials, endpoint selection, allowlists, and authoritative
-   resource handles in host state rather than guest-selected strings;
-4. define request, response, retained-output, concurrency, and deadline bounds;
-5. redact secrets and provider payloads from errors, health, and receipts; and
-6. be async and cancellation-safe when it can block.
-
-For example, a GitHub Issue source capability may accept a typed
-`{ owner, repository, number }` and return a bounded typed issue response while
-the host fixes HTTPS endpoint policy, authentication, redirects, and deadlines.
-
-The built-in GitHub capabilities authorize the fixed `github.com` read API,
-not one catalog-pinned Resource identity:
-
-```kdl
-github-pr auth-executable="/nix/store/.../bin/gh" connect-timeout-ms=3000 total-timeout-ms=10000
-github-issue auth-executable="/nix/store/.../bin/gh" connect-timeout-ms=3000 total-timeout-ms=10000
-```
-
-The catalog fixes an absolute GitHub CLI executable. The host uses that
-executable to resolve durable GitHub CLI authentication for `github.com`,
-retains the bearer value as sensitive host state, fixes API origin, operation,
-headers, response limits, redirect policy, deadlines, cancellation, and public
-DNS admission, and never places a token in catalog KDL or guest memory. A
-missing credential fails the authenticated PR GraphQL operation; issue REST
-reads may remain anonymous for public repositories. The component parses the
-Resource identity and passes only validated `{ owner, repo, number }` values to
-the typed capability. This lets one scheme profile observe every repository
-visible to that user credential without granting the guest a URL or generic
-HTTP capability.
-
-`github-pr` accepts only
-`github-pr://github.com/<owner>/<repo>/pull/<number>`. Its selector contains
-only optional `topics`; identity fields in selectors and the former short URI
-are rejected. It performs one fixed GraphQL query with bounded review-request
-and status-rollup connections. Snapshot schema
-`dev.schickling.github-pr.snapshot.v1` contains normalized repository,
-pull-request, CI, and facet data. Initial publications emit
-`ci.failure`, `mergeability.conflict`, `review.requested`, and `terminal`;
-later publications emit only changed facet topics. Ordered facts are `pr`,
-`state`, and `ci`.
-
-`github-issue` accepts only
-`github-issue://github.com/<owner>/<repo>/issues/<number>` with the same
-topics-only selector rule. It conditionally reads the issue and, when comments
-exist, exactly the latest comment page with `per_page=1`; only the comment
-`updated_at` metadata crosses into normalization. Snapshot schema
-`dev.schickling.github-issue.snapshot.v1` contains normalized issue,
-discussion, and facet data. Initial publications emit `body`, `state`,
-`labels`, `assignment`, and `discussion`; later publications emit only topics
-whose corresponding semantic fields changed. Ordered facts are `issue`,
-`state`, and `comments`.
-
-Both host adapters retain bounded source state by authoritative snapshot
-digest; the issue adapter additionally retains validated REST ETags. An issue
-source-level 304 or any snapshot differing only in `observedAt` produces
-`unchanged`; every other invocation produces exactly one atomic
-`published`, `unchanged`, or redacted `failed` result. Partial multi-request
-observations are never published.
-
-A local PTY statistics capability may accept a closed `scope` variant while the
-host fixes the executable, argument shape, empty environment, working
-directory, output caps, deadline, and process containment. An interface that
-accepts a URL, executable path, arbitrary argument vector, environment, cwd,
-filesystem path, socket address, or shell text is generic authority even if its
-package name sounds domain-specific and is non-conforming.
-
-Cancellation owns both sides of the boundary. Epoch interruption bounds
-non-yielding guest CPU; cancellation or drop of the invocation future must
-cancel blocking host imports; capability implementations must reap owned work;
-and Store drop occurs only after the in-flight call no longer borrows it. A
-cancelled observation cannot commit even if the component already returned a
-value.
-
-The executor enforces finite component-byte, memory, table, fuel, result, and
-deadline bounds as one versioned Engine policy. Snapshot bytes decode to at
-most 1 MiB; canonical selector JSON is at most 16 KiB; health and failed-result
-diagnostics are at most 16 KiB UTF-8; and one `Publication` carries at most 32
-ordered facts with the key and value limits in
-[`PROFILE-R16A`](./requirements.md). Bounds are checked before allocation or
-decoding where the typed transport permits. Values are rejected, never
-truncated.
-
-Observation uses one directly linked provider component. There is no
-long-lived runtime topology, stdin/stdout protocol, runtime-selected WAC graph,
-or parallel native-provider lifecycle. Provider ETags, cursors, conditional
-caches, rate limits, webhook repair, and backoff therefore live in bounded
-host-owned domain capability state or explicit durable provider state, never
-in Store lifetime.
-
-## Demand invocation (PROFILE-R16B..R16D)
-
-Demand remains deny-by-default. A descriptor must declare `demand` before the
-host supplies a positive demand watermark in `ObserveRequest`. A missing
-watermark is an ordinary scheduled observation; a present watermark identifies
-host work but is not provider history, a provider-specific reconcile command,
-or authority to mutate provider state.
-
-For each active binding generation the host keeps at most one observation in
-flight and one latest trailing demand watermark. Demand admitted during the
-in-flight invocation survives its result and coalesces into the trailing
-invocation. Replacement of the binding generation fences the old invocation.
-Executor failure provides failure evidence. A client wait deadline limits only
-that client's wait and never cancels admitted demand.
-
-The private durable request and receipt records remain bounded to 64 KiB and
-use schema identities `st2.resource-observe-request.v1` and
-`st2.resource-observe-receipt.v1`. One supervisor scope admits at most 256
-unresolved requests and scans at most that cap. An admitted request remains the
-durable retryable intent until a terminal receipt commits; in-memory enqueue,
-client disconnect, wait expiry, and nonterminal receipts do not transfer or
-cancel ownership.
-
-Receipt statuses are camelCase. `accepted` and `backpressured` are nonterminal.
-The terminal set is exactly `settledUnchanged`, `settledChanged`,
-`settledFailed`, `absentBinding`, `staleGeneration`, and
-`providerUnavailable`. Only `settledChanged` carries the host-computed digest.
-An active provider without `demand` maps to `absentBinding` with diagnostic
-`the profile component does not declare the demand capability`. A client
-generation older than the resident generation is `staleGeneration`; a newer
-generation remains queued until supervisor refresh.
-
-## Fenced atomic publication (PROFILE-R14, R16)
-
-Before invocation the host reads the binding's current state and creates:
-
-```rust
-ProposalFence {
-    generation,
-    revision,
-    prior_digest,
-}
-```
-
-`generation` changes when the binding is replaced. `revision` advances only on
-a committed publication in that generation. `prior_digest` is the current
-carrier digest or absence. The fence belongs to the host invocation; the
-component cannot choose it or refresh it after observation.
-
-`Unchanged` closes the observation without mutation. `Failed` records bounded
-health and preserves the last proven carrier. For `Published`, the host pairs
-the returned `Publication` with the invocation fence, validates current binding
-identity, schema and media type, byte and fact bounds, published topics,
-selector relevance, and path containment, then computes the authoritative
-snapshot digest and deterministic proposal identity.
-
-The validated internal `PublicationIntent` carries binding identity, the
-deterministic `proposal_id`, generation, expected revision and prior digest,
-resulting digest, selected topics, and ordered facts. It contains delivery
-intent and semantic metadata, not snapshot bytes or provider credentials.
-
-The proposal ID is:
-
-```text
-SHA-256(
-  "st2.resource-publication-proposal.v1\0" ||
-  serde_json::to_vec(ProposalIdentity {
-    bindingId,
-    generation,
-    expectedRevision,
-    priorDigest,
-    digest,
-    selectedTopics,
-    facts
-  })
-)
-```
-
-`ProposalIdentity` is serialized as camelCase JSON with fields in exactly the
-displayed order. `digest` is the host-computed accepted snapshot digest;
-`selectedTopics` and ordered `facts` are the post-validation semantic envelope.
-Including that envelope prevents equal carrier bytes with conflicting delivery
-meaning from sharing an identity.
-
-```rust
-ProposalCommit::Committed(PublicationCommit)
-ProposalCommit::AlreadyCommitted(PublicationCommit)
-ProposalCommit::Unchanged { generation, revision, digest }
-ProposalCommit::StaleGeneration { actual_generation, actual_revision }
-ProposalCommit::StalePrior {
-    actual_generation,
-    actual_revision,
-    actual_digest,
-}
-
-PublicationCommit {
-    proposal_id,
-    generation,
-    resulting_revision,
-    digest,
-}
-```
-
-`Committed` is the single state transition. `AlreadyCommitted` is an
-idempotent retry of the same deterministic proposal and returns the original
-commit identity. `Unchanged` reports equal accepted bytes without advancing
-revision or creating an outbox intent. `StaleGeneration` fences replacement.
-`StalePrior` rejects a competing proposal whose expected revision or digest is
-no longer current. Concurrent proposals from one prior state therefore have at
-most one winner.
-
-The storage transaction makes these values visible together:
-
-```text
-contained carrier bytes
-current generation + resulting revision + digest + freshness
-lastIntent: complete deterministic PublicationIntent
-pending delivery reducer state
-```
-
-Before that publication point, readers observe the complete prior state and no
-new intent. After it, readers observe the complete successor and its intent.
-A process crash before publication leaves the prior state authoritative. A
-crash after publication but before acknowledgement leaves the successor and
-intent durable. Retrying the same proposal returns `AlreadyCommitted`; an
-outbox worker may retry delivery by `proposal_id` until its durable
-acknowledgement exists.
-
-Equal snapshot bytes return `Unchanged`; they do not advance revision or create
-an intent. The initial accepted publication changes the binding from
-unavailable to readable; when it has selected topics, its atomic intent
-schedules the same superseding invalidation as a later relevant change.
-
-Atomic publication is runtime-neutral: passive observation and the component
-executor submit the same fenced `Publication` to one host API. The foundation
-is conforming without an enabled executor, but observable provider execution is
-conforming only through the component world; there is no native fallback.
-
-## Semantic invalidation and catch-up (PROFILE-R17..R20)
-
-For every changed digest, including the initial accepted publication, proposal
-validation preserves the `Publication`'s ordered facts and intersects its topics
-with the normalized binding selector before commit. The resulting
-`PublicationIntent` retains selected topics and facts with the committed
-snapshot digest. An empty intersection updates canonical state and freshness
-but requires no agent wake.
-
-The durable binding and catch-up state is:
-
-```text
-generation: u64
-revision: u64
-current_snapshot_digest: Digest?
-last_intent: PublicationIntent?
-last_delivered_digest: Digest?
-pending_relevant_change: bool
-pending_from_last_intent: bool
-pending_selected_topics: Topic[]
-pending_facts: ResourceFact[]
-deliverable: bool
-```
-
-`last_intent` is the full deterministic intent: proposal and binding IDs,
-generation, expected revision, prior and resulting digests, selected topics,
-and ordered facts. `last_commit()` derives its receipt from that authority
-rather than storing a second commit record. When pending delivery refers to
-`last_intent`, `pending_from_last_intent` is true and the pending topic/fact
-fields stay empty; readers derive that envelope from the intent.
-
-Publication never calls the event sink inside the commit transaction. Recovery
-folds an eligible staged WAL intent into this durable state atomically with the
-carrier and removes the WAL; eligibility requires its resulting digest to match
-the authoritative carrier. A separate outbox worker reads `last_intent`. If the
-resulting state is relevant and delivery is available, the worker emits one
-event on the existing built-in `resync` stream:
-
-```text
-stream = resync
-key = binding name
-supersede = true
-idempotency = PublicationIntent.proposal_id
-subject = <binding> · <up to three whole facts> [<topics>]
-body = { binding, snapshotDigest, topics, facts }
-```
-
-Subjects are at most 96 Unicode scalars. Facts retain publication order and are
-included only whole; topic space is reserved before facts are admitted. If no
-fact fits, a compatible bounded fallback remains. The durable body retains the
-complete bounded fact list. It contains no snapshot bytes, provider payload,
-credential, URI, reason, or provider cursor. Existing inbox storage, DING
-rendering, deduplication, and supersession apply unchanged. Multiple topics for
-one atomic publication produce one invalidation.
-
-Acknowledgement is a separate durable transition keyed by deterministic
-`proposal_id`. Loss of acknowledgement leaves the intent retryable; a retry
-uses the same event identity. An obsolete intent is not replayed as history:
-the worker reconciles against current binding state and may replace delivery
-with at most one invalidation for the then-current digest.
-
-If delivery is unavailable, a relevant publication sets
-`pending_relevant_change` and initially points it at `last_intent` without
-duplicating topics or facts. Before a later irrelevant publication replaces
-`last_intent`, the reducer materializes the older relevant envelope into
-`pending_selected_topics` and `pending_facts` and clears
-`pending_from_last_intent`. The later publication may advance the current
-digest but does not clear pending relevance. When delivery becomes available,
-catch-up emits at most one invalidation for the then-current digest with the
-retained latest relevant envelope, and clears pending state only after durable
-acknowledgement. No transition backlog is delivered. This is level-triggered
-current-state catch-up, not event replay.
-
-Health has separate component loading, descriptor, selector, capability,
-observation, proposal validation, publication, and delivery stages. Every stage
-reports affected scheme and binding without including URI credentials or
-provider payloads. The last proven snapshot stays readable with explicit
-freshness when observation fails; failure never relabels old bytes as newly
-observed state.
-
-## Deliberate exclusions and evidence gates (PROFILE-R21..R25)
-
-| Exclusion | Evidence required before reconsideration |
-| --- | --- |
-| WASIp3 production execution | A stable Wasmtime/WIT toolchain and component ecosystem, a production provider requirement that WASIp2 cannot express, cross-version fixtures, and cancellation plus capability-containment evidence at least as strong as the WASIp2 suite. |
-| Store or instance pooling | Representative provider profiles showing fresh Store creation materially violates an accepted latency or resource bound, plus an exhaustive reset proof covering guest memory, tables, resources, host state, traps, fuel, deadlines, async imports, and cancellation with zero cross-observation leakage. |
-| Generic exec, raw HTTP, arbitrary filesystem, or raw socket authority | A real provider operation that cannot be represented as a narrower typed domain interface, an explicit threat and credential model, fixed authority and resource bounds, cancellation/containment tests, and an accepted decision for the enlarged trust boundary. |
-| Parallel native or host-process provider framework | A production provider that cannot run through the component world, measurements showing the incompatibility is fundamental rather than packaging cost, and evidence that a second lifecycle, health, fencing, and security model is safer and simpler than extending typed capabilities. |
-| Runtime WAC or provider-selected component graph | At least two production providers requiring runtime composition, a closed graph ownership and versioning model, transitive capability review, deterministic failure/fencing semantics, and measurements showing host linkage is the limiting constraint. |
-
-These are evidence gates, not deferred implementation commitments. Until a gate
-is met and an accepted decision changes the contract, the excluded mechanism is
-non-conforming.
-
-## Design questions
-
-- **DQ-P1 Component compatibility:** Prove old-component/new-host,
-  new-component/old-host, provider-world, and domain-capability compatibility
-  with frozen WIT fixtures and a cross-version conformance matrix before
-  independently released third-party components or capabilities.
-- **DQ-P2 Provider observability:** Derive the minimum low-noise component,
-  capability, proposal, publication, freshness, outbox, and delivery health
-  surfaces from one operated GitHub provider.
-
-Resolved design questions and their evidence remain recorded in
-[`open-questions.md`](./open-questions.md).

-# Resource read surfaces and link-plane adoption
-
-**Date:** 2026-08-27
-**Catalog:** one live catalog, host `dev3`, 655 agent declarations.
-
-## Question
-
-Do the two edges called *resource* — declared bindings and `st2 resource` link
-records — name the same things, and is the link plane still carrying work?
-
-## Method
-
-Aggregate shell census over every `agent.kdl` and every
-`resources/links/*.md` in the catalog: URI and URL sets compared exactly and
-after normalization (trailing slash stripped, `%20` decoded) on the schemes both
-planes use; link-record creation time read from the `<unix-ms>` filename prefix;
-readers of the link plane found by searching the source tree for `links_dir`.
-
-A shell renderer
-([`render-read-surfaces.sh`](./render-read-surfaces.sh)) prints candidate
-`st2 resource ls` shapes for one declaration, reading the same bytes st2 reads.
-It was checked against the two declarations in
-[dotfiles#2071](https://github.com/schickling/dotfiles/pull/2071) —
-`dotfiles.fb-batch1.docs.worker` (5 bindings, 0 link records) and
-`dotfiles.vista.pr1506-final.worker` (2 bindings, 14 link records).
-
-## Result
-
-The renderer reproduced both reported outputs exactly, including
-`# 0 resources for dev3.dotfiles.fb-batch1.docs.worker`, so it is faithful to
-the surface under test.
-
-Disjointness:
-
-- 1161 bindings across 647 declarations; 241 link records across 82.
-- 889 distinct binding URIs, 233 distinct link URLs, **0 coinciding** under
-  exact match and under normalization on all five shared schemes (`file`,
-  `worktree`, `git-commit`, `https`, `st2-message`).
-- 81 of 82 link-record-carrying declarations also carry bindings.
-- 13 path-prefix hits across 6 declared worktrees: link outputs living inside a
-  declared worktree. Containment, not identity.
-
-Link-plane adoption:
-
-- 82 of 655 declarations (12.5%) ever wrote a link record.
-- Creation peaked 2026-08-07 through 08-09 (44, 45, 29 records/day), then
-  decayed; 5 records on 2026-08-26 and none since.
-- 14 of the 25 most recent records come from a single declaration on one day.
-- **The only reader of link records in the source tree is the
-  `st2 resource ls|read` verb itself.** No projection, roster, doctor, or other
-  consumer reads them.
-- `axe work update --artifact <path> --pty <name>` covers the same job, and
-  matches the observed `relation` values (`output` 185, `evidence`, `produces`)
-  and the 8 `pty://` URLs.
-
-Binding realization:
-
-- Self-state carriers realize into the agent's `resources/` directory:
-  `dev.schickling.agent-goal://` → `resources/goal.md`,
-  `decision-tree://` → `resources/context/decisions/`.
-- `resources/context/now.md` exists on 605 of 655 declarations and is declared
-  by none; no binding URI anywhere mentions it.
-
-Reason-field quality:
-
-- 987 of 1161 bindings carry the placeholder
-  `reason="Legacy binding retained without recorded rationale."` from a
-  2026-08-22 backfill. Declarations touched on 2026-08-26 and 2026-08-27 are
-  26 of 27 placeholder-free and carry real prose.
-
-## Conclusion
-
-The two planes are disjoint by construction, not by coincidence: bindings carry
-what an agent is for, link records carry what it produced. A shared descriptor
-type would deduplicate nothing.
-
-The link plane is legacy. It is write-only by construction, adopted by an eighth
-of the fleet, decaying, and superseded by `axe work`. The `resources/` directory
-is not a third meaning of the word — it is the realization surface for the
-bindings, and remains canonical for an agent's resource files.
-
-`reason` is working; the 987 placeholders are one un-cleaned backfill.
-
-## VRS Impact
-
-- [spec.md](../spec.md): the two edges, their disjointness, the write-cost
-  asymmetry that caused the drift, and the retirement of the link plane.
-- [ontology.md](../../ontology.md): `Resource`, `Resource binding`,
-  `linked record` (retired), `agent resource directory`, `working state`.
-- [open-questions.md](../open-questions.md): DQ-R4 (write-cost, unresolved),
-  DQ-R7 (placeholder cleanup), DQ-R8 (upstream sync).
-- No requirements change. A delta was drafted for the working-state carrier and
-  withdrawn once [#351](https://github.com/compoundingtech/st2/pull/351) rewrote
-  R20; see [decision 0012](../../.decisions/0012-working-state-is-a-declared-carrier.md)
-  Amendment 1.
-
-## Limits
-
-One catalog, one host, one downstream convention. Zero overlap is strong
-evidence that the planes are disjoint *as used here*; it does not prove no
-consumer would ever want to name one Resource from both. The renderer covers
-read shape only and says nothing about write cost, which
-[DQ-R4](../open-questions.md) holds open.

-  gives `st2 resource add|remove|rename` mediated read-modify-CAS-publish, which

-  Resolves by: a downstream that actually generates declarations stating which
-  shape it needs, or a decision that st2 does not model this.
-

-  makes the rewrite cheap. `inactive-reason` is used once fleet-wide, too little
-  evidence to judge. Resolves by: a cleanup pass, or a decision to let the
-  placeholders age out through ordinary republication.
-
-- **DQ-R8 When does the canonical Agent Spec get synced?** Upstream
-  `evals/AGENT-SPEC.md` was last touched 2026-08-20; #307 landed 2026-08-23. The
-  canonical document still describes the envelope as closed at name and `uri`,
-  and still says unsupported properties such as `_tag` fail validation, without
-  mentioning that `reason` is now required. st2 did not diverge deliberately —
-  the document is three days stale, and it is the authority st2's own ontology
-  cites. Resolves by: an upstream sync. Until then, treat
-  [`crates/agent-spec/src/spec.rs`](../../../crates/agent-spec/src/spec.rs) as
-  the live contract.
-
-- **DQ-R10 Do the 241 orphaned linked-record files get removed?**
-  [Decision 0011](../.decisions/0011-the-linked-record-plane-is-retired.md)
-  leaves them in place: most belong to retired declarations, and migrating them
-  into `axe work` is blocked because it writes to a gitignored per-worktree path
-  those declarations no longer have. They are unreferenced once the verb is gone.
-  Resolves by: a decision to sweep `resources/links/` during some later catalog
-  maintenance, or to leave them as inert history.

-# Resource
-
-A Resource is an externally identified thing an agent points at. This document
-states the one edge that reaches it, why a second edge existed and was retired,
-and what the surface looks like once *resource* names one concept.
-
-Terms are defined in [ontology.md](../ontology.md): [Resource](../ontology.md#resource),
-[Resource binding](../ontology.md#resource-binding),
-[agent resource directory](../ontology.md#agent-resource-directory),
-[working state](../ontology.md#working-state).
-
-Decisions: [0011](../.decisions/0011-the-linked-record-plane-is-retired.md),
-[0012](../.decisions/0012-working-state-is-a-declared-carrier.md),
-[0013](../.decisions/0013-resource-is-a-mediated-write-surface.md), and
-[0014](../.decisions/0014-resource-profiles-are-state-first-read-and-observe-capabilities.md).
-
-## The edge
-
-One agent, one binding, one Resource:
-
-```kdl
-resource "work" reason="PR this agent is preparing." \
-  uri="github-pr://github.com/example/project/42"
-```
-
-The positional name is an agent-local semantic role, unique within one agent.
-`uri` is an RFC 3986 absolute URI preserved byte-for-byte, and it is the
-Resource's identity. `reason` is required prose saying why this agent carries
-it. `inactive-reason`, when present, retains a reference that is no longer
-current and explains why.
-
-`selector`, when present, is profile-specific observation configuration. KDL
-stores normalized compact JSON in a raw string:
-
-```kdl
-resource "work" reason="PR this agent is preparing." \
-  uri="github-pr://github.com/example/project/42" \
-  selector=#"{"topics":["ci.failure","review.requested"]}"#
-```
-
-The canonical renderer chooses the smallest safe raw-string hash fence. JSON
-and TOML Agent Spec forms carry the selector as a native JSON value. A selector
-is not Resource identity or authority, and an observable profile must validate
-it before registration; omission selects the profile default.
-
-The URI is never normalized, and its scheme is the exact lookup key for an
-optional, catalog-declared Resource Profile
-([`07-resource-profile`](../07-resource-profile/requirements.md), landed in
-[#351](https://github.com/compoundingtech/st2/pull/351)). Scheme meaning stays
-downstream-owned, st2 ships no built-in profiles, and an unregistered scheme
-stays opaque ([R20](../requirements.md)). Possession of a URI grants no
-authority, access, or capability
-([#61](https://github.com/compoundingtech/st2/issues/61)).
-
-Bindings are desired state. They change through publication under
-compare-and-swap, and a binding-only change never stops, replaces, or relaunches
-healthy work ([R21](../requirements.md)).
-
-The Rust type is
-[`crates/agent-spec/src/spec.rs`](../../../crates/agent-spec/src/spec.rs)
-`Resource { name, uri, reason, inactive_reason, selector }`.
-
-## Identity and realization
-
-A binding names a carrier; the carrier's bytes live in the
-[agent resource directory](../ontology.md#agent-resource-directory):
-
-| binding | scheme | realizes as |
-|---|---|---|
-| `notes` | `agent-notes` | agent notes |
-| `goal` | `dev.schickling.agent-goal` | `resources/goal.md` |
-| `decisions` | `decision-tree` | `resources/context/decisions/` |
-| `working-state` | `working-state` | `resources/context/now.md` |
-
-The URI is identity; the path is realization. st2 does not resolve one into the
-other, and `resources/` is not a second sense of *resource* — it is where
-bindings land. The directory remains canonical for an agent's resource files and
-also holds the message planes (`inbox/`, `archive/`, `sent/`) and scratch
-material (`tmp/`), which are not carriers.
-
-`working-state` is the sixth self-state carrier
-([decision 0012](../.decisions/0012-working-state-is-a-declared-carrier.md)).
-Before it, 605 of 655 declarations on one live catalog had a
-`resources/context/now.md` and none declared it.
-
-## Surface
-
-`st2 resource` reads and writes the binding plane for one agent:
-
-```text
-st2 resource ls [<identity>] [--json]
-st2 resource read [<identity>] <name> [--json]
-st2 resource refresh [<identity>] <name> [--agent <identity>] [--wait <seconds>] [--json]
-st2 resource add <name> --uri <uri> --reason <text> [--inactive-reason <text>] [--selector-json <json>] [--agent <identity>] [--json]
-st2 resource remove <name> [--agent <identity>] [--json]
-st2 resource rename <old> <new> [--agent <identity>] [--json]
-```
-
-```
-$ st2 resource ls dev3.dotfiles.fb-batch1.docs.worker
-# 5 resources for dev3.dotfiles.fb-batch1.docs.worker
-  decisions          decision-tree://dev3/dotfiles.fb-batch1.docs.worker
-  dotfiles-checkout  worktree://dev3/…/2026-08-26-fb-batch1-docs
-  friction-log       dev.schickling.agent-friction-log://dev3/dotfiles.fb-batch1.docs.worker

-  private-notes      dev.schickling.agent-private-notes://dev3/dotfiles.fb-batch1.docs.worker
-```
-
-Rows are ordered by binding name, not declaration order — declaration order has no
-meaning. The name column pads to the widest name in the listing. The worktree URI
-above is elided at `…`; the command prints it in full.
-
-The name column is aligned to the widest name; the checkout URI is elided in this
-document, not by `ls`, which prints every URI verbatim.
-
-The read surfaces project one agent's declared bindings; before them, bindings
-were visible only through `st2 agents --json`. `ls` takes an optional leading
-identity. `read` and `refresh` treat one positional argument as a binding on the
-caller and two as `<identity> <name>`; `refresh --agent <identity> <name>` is
-the equivalent explicit-target form and cannot be combined with a leading
-identity. Every form defaults through `--as` / `$ST_AGENT`, and every verb
-inherits `--catalog`, `--root`, `--as`, and `--host`.
-
-`refresh` asks the resident observable profile runtime for one atomic current
-observation. It never rewrites the Resource declaration. `--wait` bounds only
-the client wait; timeout or disconnect leaves admitted demand queued. JSON and
-durable receipt status values are camelCase; human CLI status text is
-kebab-case.
-
-The writes take `--agent <identity>`, perform read-modify-CAS-publish
-internally, and emit a stable `--json` receipt, so the caller never renders KDL.
-Full-catalog validation, exact-target selection, compare-and-swap, and
-fail-closed concurrent-change behavior are preserved, and a binding-only
-change does not stop, replace, or relaunch healthy work
-([R21](../requirements.md)). This is the fourth instance of the pattern in
-[`src/agent_author.rs`](../../../src/agent_author.rs), after streams, desired
-state, and presentation
-([decision 0013](../.decisions/0013-resource-is-a-mediated-write-surface.md)).
-Decisions [0011](../.decisions/0011-the-linked-record-plane-is-retired.md) and
-0010 carry "merge and acceptance approval required: upstream maintainers".
-
-Each write is idempotent on its outcome rather than its attempt: `add` upserts
-one name, reporting identical bytes as unchanged without republishing them;
-`remove` reports an already-absent name as unchanged; and `rename` refuses an
-absent name and a collision, since names are unique within one agent. A mutation
-refuses an invalid URI, an empty reason, and a Nix-owned declaration, and
-preserves the URI byte-for-byte along with the declaration's unrelated bytes.
-
-Bindings remain projected through `st2 agents --json` as opaque descriptors, per
-`invariants.md`.
-
-## The retired plane
-
-`st2 resource add|ls|read|remove` previously managed **linked records** — one
-markdown file per record with `url`, optional `title`/`tags`/`relation`, and an
-optional body, under `<agent-dir>/resources/links/`. An agent wrote them itself,
-without publication or CAS, to record what it produced.
-
-That plane is retired
-([decision 0011](../.decisions/0011-the-linked-record-plane-is-retired.md)).
-Recording produced artifacts is `axe work update --artifact <path> --pty <name>`.
-
-`templates/bus.st2.md` advertised `st2 resource add|ls|read|remove` to every
-agent on the bus, which is what produced the adoption measured below. It now
-carries the binding verbs instead.
-
-### Why it existed and why it went
-
-Measured on one live catalog of 655 declarations
-([experiment](.experiments/2026-08-27-resource-read-surfaces.md)):
-
-- 1161 bindings across 647 declarations; 241 linked records across 82.
-- 889 distinct binding URIs and 233 distinct linked-record URLs, **zero
-  coinciding** — exactly, and normalized across all five schemes both planes
-  used. 81 of the 82 linked-record-carrying declarations also carried bindings,
-  so the planes coexisted constantly and never named one thing.
-- The only reader of a linked record in the source tree was its own `ls`/`read`
-  verb. No projection, roster, or doctor consumed them.
-- Adoption was 12.5% of declarations and decaying: 45 records on 2026-08-08,
-  five on 2026-08-26, none after.
-
-The disjointness was semantic. Bindings carried what an agent *is for* — 728
-self-state carriers and 378 work inputs. Linked records carried what it *made* —
-196 of 241 were `output`, `produces`, `evidence`, or `verified`. Where a
-declared worktree and a linked output shared a path the relation was
-containment, the product sitting inside the input, not identity.
-
-So a shared descriptor type would have deduplicated nothing and joined nothing.
-[#122](https://github.com/compoundingtech/st2/issues/122) proposed exactly that,
-around a `_tag` field removed in #307.
-
-### What the split actually cost
-
-The remaining 19% of linked records name the mechanism: `supervises`,
-`reference`, `current-work` (which duplicates the `work` binding),
-`depends-on-slice-*`, `blocked-design`. Those are dependency and reference edges
-filed in the products plane.
-
-An agent could not cheaply record a dependency. A binding needed publisher
-authority and whole-declaration republication under compare-and-swap. So it
-wrote a linked record, because that was the plane it was permitted to write.
-
-**The drift was caused by write-cost asymmetry, not by two relations.** Retiring
-the plane removes the escape hatch; the mediated write verbs
-([decision 0013](../.decisions/0013-resource-is-a-mediated-write-surface.md))
-remove the pressure that produced it.
-
-### Reported friction
-
-Two declarations, from
-[dotfiles#2071](https://github.com/schickling/dotfiles/pull/2071): one with five
-bindings and no linked records reported `# 0 resources`; one with two bindings
-and fourteen linked records reported fourteen rows containing neither binding.
-Both answers were correct and neither surface said which question it answered.
-
-The read surfaces were also inverted against their authority. Bindings were
-governed by R20 and R21 and pinned by an invariant, and had no human surface at
-all. Linked records were governed by nothing and owned the short, obvious verb.
-An agent looking for its bindings found the linked-record verb first, because it
-was the only one whose name matched what it was looking for.
-
-The boundary had been correct in writing since 2026-07-30:
-[#61](https://github.com/compoundingtech/st2/issues/61)'s resolution states that
-`st2 resource` manages linked-reference records and does not mutate a binding.
-That sentence never reached the command's own words. With one plane, it no
-longer needs to.
-
-### Residue
-
-The 241 existing records stay in place as orphaned files. Most belong to retired
-declarations whose worktrees are gone, and `axe work` writes to a gitignored
-per-worktree path that no longer exists for them. The ontology keeps a retired
-entry so a reader who meets one can identify it.
-
-## Boundaries
-
-Nothing here claims mutation authority over the thing a URI names, and nothing
-makes possessing a URI mean something. A mediated write changes a declaration;
-it does not touch the referent.
-
-Resolution is deliberately out of scope for this document, not absent from st2:
-[#351](https://github.com/compoundingtech/st2/pull/351) owns the scheme-keyed
-Resource Profile registry under
-[`07-resource-profile`](../07-resource-profile/requirements.md). The two are
-orthogonal — a binding names a Resource whether or not any profile resolves its
-scheme, and `st2 resource` neither reads nor requires one.

-# Context signals across five harnesses, and where the numbers should be written
-
-## Question
-
-Two questions, measured together on 2026-08-29 because neither answers alone:
-
-1. **What does each maintained harness positively publish about its own context
-   window and its compactions**, and by what arithmetic does it turn that into
-   the number it shows its operator?
-2. **Where should st2 keep those numbers** — folded into the existing
-   `harness-state` record, or in a sibling record with its own guard — and what
-   does either cost in writes, in code, and in fields that already mean
-   something?
-
-A third question rode along: does anything in the fleet already detect context
-saturation, so that a new st2 record would be a second source of truth?
-
-## Method
-
-Five harness surfaces, four labs, one throwaway spike, and one read-only survey.
-All work was done on this host; nothing was committed.
-
-**Claude Code 2.1.250.** Live status-line capture with zero model turns: a
-throwaway settings file whose `statusLine.command` wrote its stdin to a file,
-run under `script` from an already-trusted worktree (a fresh scratch directory
-is blocked by the folder-trust dialog). Hook and status-line payload schemas
-were read out of the shipped bundle by grepping the bundled zod literals.
-Transcript shape was read from 1,184 local transcripts under `~/.claude/projects`.
-
-**codex-cli 0.150.1.** Protocol shapes from `codex app-server
-generate-json-schema`; the arithmetic from the openai/codex source at tag
-`rust-v0.150.1` (the packaged binary is a prebuilt tarball with no vendored
-source); live cadence and payloads from a real rollout JSONL written that day.
-
-**pi 0.84.2.** A credential-free lab: a local OpenAI-completions SSE server
-emitting usage-bearing chunks, a `registerProvider` fake provider with a
-4,000-token window, and a probe extension logging `ctx.getContextUsage()` and
-the event payload at every lifecycle event. Compaction was forced by overflowing
-the small window.
-
-**omp 18.0.9 and 18.0.3.** The same lab, ported unchanged (`pi.registerProvider`
-works on omp), run against both store paths; plus one real-credential
-`omp -p "say hi"` turn against a 272,000-token window, and a byte-level scan of
-both binaries.
-
-**OpenCode 1.18.25.** A headless `opencode serve` under isolated XDG
-directories with a free anonymous model, its `GET /event` SSE stream captured to
-a file, `GET /doc` (472 schemas), and `POST /session/{id}/summarize` to force a
-compaction.
-
-**Placement spike.** A throwaway worktree in which both placements were built
-end to end through the Claude hook path and their writes counted:
-*Option A*, a `context` sub-object inside `harness-state` with a knob selecting
-whether a token delta opens a transition; *Option B*, a sibling
-`harness-context` record with its own lock, guard, and horizon. Both compile and
-their tests pass; the sandbox carries 12–13 pre-existing unrelated failures
-(pty/network) in the full suite, and `--lib` alone is green. Write counts are
-byte-distinct landed writes per simulated Claude turn.
-
-**Prior-art survey.** Read-only grep across tokenlens, the fleet's Grafana
-dashboards and OTel conventions, the dotfiles Claude hook and status-line chain,
-the fractal TUI, and st2's own consumers.
-
-## Result
-
-### 1. Every harness answers, and no two answer the same way
-
-| Harness (version) | Numerator | Denominator | Percent as the harness shows it |
-| --- | --- | --- | --- |
-| Claude Code 2.1.250 | `input + cache_creation + cache_read` of the last response | `context_window_size` (status line only) | integer, clamped 0..100 |
-| codex-cli 0.150.1 | `last.totalTokens` − 12,000 | `modelContextWindow` − 12,000 | rounded "% context left" |
-| pi 0.84.2 | `getContextUsage().tokens` = last assistant `totalTokens` | `.contextWindow` | float; `null` right after compaction |
-| omp 18.0.9 | `getContextUsage().tokens` = last assistant `input` | `.contextWindow` | float |
-| OpenCode 1.18.25 | last non-summary assistant `tokens.total` | `GET /config/providers` `limit.context` | none shown |
-
-Verbatim, from the live Claude status-line capture:
-
-```json
-"context_window": { "total_input_tokens": 0, "total_output_tokens": 0,
-                    "context_window_size": 1000000,
-                    "current_usage": null, "used_percentage": null,
-                    "remaining_percentage": null },
-"cost": { "total_cost_usd": 0, "total_duration_ms": 36418, ... },
-"model": { "id": "claude-fable-5", "display_name": "Fable 5" },
-"rate_limits": { "five_hour": { "used_percentage": 31, ... },
-                 "seven_day": { "used_percentage": 55.0, ... } }
-```
-
-and the bundle's own arithmetic, verbatim:
-
-```js
-let r = e.input_tokens + e.cache_creation_input_tokens + e.cache_read_input_tokens,
-    o = Math.round(r / t * 100), u = Math.min(100, Math.max(0, o));
-return { used: u, remaining: 100 - u }
-```
-
-Codex's, from `protocol.rs` and the TUI crate (the same constant and the same
-function body duplicated in both):
-
-```rust
-const BASELINE_TOKENS: i64 = 12000;   // "Includes prompts, tools and space to call compact."
-let effective_window = context_window - BASELINE_TOKENS;
-let used = (self.tokens_in_context_window() - BASELINE_TOKENS).max(0);
-```
-
-Recomputed against the measured rollout (window 258,400, `last.totalTokens`
-92,283): 67% left, 33% used. A naive `last.inputTokens / window` gives ~36% —
-close enough to pass review and wrong by construction.
-
-**The measured traps, one per harness:**
-
-- **Codex:** `total_token_usage.total_tokens` reached 2,235,329 against a
-  258,400-token window in one session. It is lifetime spend; anything dividing
-  it by the window reports >800%.
-- **pi:** after a compaction `getContextUsage()` returns
-  `{tokens: null, contextWindow: 4000, percent: null}` and stays null across a
-  process restart until the next assistant usage arrives. pi positively says it
-  does not know.
-- **omp:** the same call, a different quantity. Against a fake provider
-  reporting prompt tokens of 900 / 9,900 / 22,500, `tokens` returned exactly
-  those figures — prompt-only input, where pi returns `totalTokens`.
-- **OpenCode:** `summary` is truthy on user messages (an object `{diffs: []}`),
-  so `if (m.summary)` counts every user turn; and after a compaction the newest
-  assistant message is the summarizer's own, whose `tokens.total` was 1,511 —
-  the cost of summarizing, not the new context size.
-- **Claude:** `used_percentage` is `null` until the first API response, while
-  the window is populated from the start.
-
-Compaction edges, all captured or read from the shipped schema:
-
-| Harness | Edge | Carries | Count source |
-| --- | --- | --- | --- |
-| Claude 2.1.250 | `PreCompact` / `PostCompact` hooks; `SessionStart source=compact` | `trigger: manual \| auto`; no sizes | st2 must count |
-| Codex 0.150.1 | `contextCompaction` thread item (`thread/compacted` deprecated) | nothing | st2 must count |
-| pi 0.84.2 | `session_compact` | `reason: manual \| threshold \| overflow`, `tokensBefore` | `sessionManager.getEntries()`, durable |
-| omp 18.0.9 | `session_compact` | timestamp only, **no reason** | `sessionManager.getEntries()`, durable |
-| OpenCode 1.18.25 | `session.compacted` | `{sessionID}` only | assistant messages with `summary === true` |
-
-The Claude transcript's `compact_boundary` line does carry `preTokens` /
-`postTokens`, but zero of 1,184 local transcripts contain one — the shape is
-verified from the binary, not observed in this corpus.
-
-### 2. Where the numbers should live: the guard decides, not the placement
-
-Byte-distinct landed writes per simulated Claude turn:
-
-| Tool calls in the turn | Today | A, coalesced | A, strict | B, sibling |
-| --- | --- | --- | --- | --- |
-| 0 | 2 | 2 | 2 | 1 |
-| 5 | 2 | 2 | 12 | 1 |
-| 15 | 2 | 2 | 32 | 3 |
-
-Five findings, in the order they constrain the choice:
-
-1. **A-strict corrupts two existing fields.** A transition resets `sinceMs`
-   ("when the current state was entered") and increments `transitions`. Making
-   every token delta a transition turns both into turn counters, so "idle for 40
-   minutes" becomes unrecoverable. A-strict is not actually available.
-2. **A-coalesced reports the number the turn started with.** Across 40 readings
-   inside one turn the record still held the first, until the five-minute
-   refresh — measured, not argued. Acceptable for "roughly how full is this
-   agent", wrong for "warn me before it compacts".
-3. **A's freshness needs a second stamp.** `heartbeat()` re-stamps the record
-   without re-reading the source, so a context field inside it would look fresh
-   while being arbitrarily old. The fix is a `context.observedAtMs` — which is
-   B's separate horizon, moved inside A's record.
-4. **A drops the numbers on every indeterminate read** — the seven `unknown`
-   derivations (stale, session-dead, malformed, claimed, unfenced, future-skew,
-   unsupported-schema) each build a fresh value that loses `context`. That is
-   exactly the wedge case: an agent at 190k of 200k whose state has gone
-   indeterminate reports nothing. It is a cost rather than a wall — seven return
-   sites have the parsed record in hand and could thread the field through — but
-   it is work A pays and B gets for free.
-5. **The sibling is inert where it matters.** `src/watch.rs` is an allowlist
-   (inbox subtree plus the presence record), so a new sibling file wakes no
-   delivery pump with no production change, and the existing watcher test stays
-   green untouched. Only the invariant row's prose, which enumerates siblings by
-   name, would need editing.
-
-Costs on the other side of the ledger, also measured: B is roughly 432
-production lines against A's ~261 (~65% more), and adds one file per agent.
-Both options pay the same unrelated cost of registering one new Claude hook
-(`PreCompact`), which changes two expansion snapshots and the maintained example
-declaration.
-
-The discriminator is the guard, not the placement. `observe_inner`'s suppression
-test is an equality check over a categorical tuple; the two policies it can
-express are "write on no delta" and "write on every delta". What the measurement
-says is right — write when the number moved meaningfully, and at most once a
-minute otherwise — needs a prior-value comparison, an elapsed-since-reading
-check, and a move-fraction test folded into the most invariant-dense function in
-that module. The sibling expresses it in a twenty-line guard with nothing else
-in scope.
-
-### 3. Nobody else is watching, and the one adjacent owner is retrospective
-
-A repo-wide survey found no context-saturation detection anywhere in the fleet.
-The dotfiles Claude status-line renderer already parses
-`context_window.used_percentage` and prints it to stdout without persisting
-anything; the dotfiles hook chain maps `PreCompact` to a transient
-`status=compacting` PTY event with no counter. tokenlens — the fleet's
-registered token and cost producer — has a `compaction_count` column derived
-retrospectively from transcripts and **no context-window column at all**, and
-its own documentation lists context replay under future work. Its Grafana
-dashboard's "Context Overhead Share" panel is a cache-waste heuristic, not
-window fill. Nothing scrapes st2.
-
-So this record is a first source, not a second — with one overlap to manage: a
-live st2 compaction counter and tokenlens's transcript-derived one would be two
-answers to one question.
-
-### 4. Correction: omp 18.0.3 always had `getContextUsage`
-
-The 18.0.3 capture in
-[`06-omp-driver/.experiments/2026-08-25-omp-harness-integration.md`](../../06-omp-driver/.experiments/2026-08-25-omp-harness-integration.md)
-records that the event-handler `ctx` exposes `{ui}` only. Running the 2026-08-29
-probe unchanged against the 18.0.3 binary returns the identical `ctx` key set as
-18.0.9 and a working call (`session_start {"tokens":2078,"contextWindow":4000,
-"percent":51.95}`), and `getContextUsage` occurs 35 times in each of the two
-binaries. The earlier enumeration missed it: a probe artifact, not a version
-change. `signal` and `agent_settled` are genuinely absent from both, exactly as
-that capture says.
-
-## Conclusion
-
-The five harnesses answer the occupancy question well enough to build on, and
-badly enough that a single st2 formula is not available: the numerator differs
-(last-response total, prompt-only input, an st2-computed join), the denominator
-differs (raw window versus a window with a fixed 12,000-token baseline removed),
-and two harnesses positively report "I do not know" where a naive producer would
-report zero. Publishing each harness's own number, discriminated by the
-`harness` field, is the only shape that agrees with what an operator sees.
-
-For placement, the numeric axis wants a different write guard than the
-categorical one, and the categorical record's guard cannot express it without
-redefining `sinceMs` and `transitions`. The sibling record costs ~65% more
-production code and one more file per agent, and buys a guard that fits the
-axis, numbers that survive an indeterminate state, and an independent staleness
-horizon.
-
-Both harness-coupled constants — Codex's 12,000 baseline and omp's input-only
-semantics — are properties of a build, not of an API contract, and belong under
-the same version-gate discipline the omp driver already uses.
-
-## VRS Impact
-
-- Establishes [`08-harness-context/`](../requirements.md) and its producer table
-  (HC-R11), the harness-native vocabulary (HC-A04, HC-R02), the withholding rule
-  (HC-R03), and the compaction accounting table (HC-R12).
-- Grounds the placement and guard decision recorded in
-  [decision 0014](../../.decisions/0014-harness-context-is-a-sibling-numeric-record.md),
-  including the write-amplification table and finding 5 (the delivery watcher's
-  allowlist), which is why HC-R08 costs no production change.
-- Sets the provisional constants in the spec's write guard and opens `DQ-C1`:
-  the table above is one harness on one host, not a fleet benchmark.
-- Supplies the version pins HC-R13's fixtures must assert: Claude Code 2.1.250,
-  codex-cli 0.150.1, pi 0.84.2, omp 18.0.9, OpenCode 1.18.25.
-- Resolves `DQ-C3`: the status-line precedence the Claude producer assumes is
-  captured, and the consequence is ratified as HC-R18 (the tee must chain).
-- Corrects the 18.0.3 `ctx` enumeration in
-  [`06-omp-driver/.experiments/2026-08-25-omp-harness-integration.md`](../../06-omp-driver/.experiments/2026-08-25-omp-harness-integration.md),
-  where the correction is appended. The same false claim also appears in
-  [`2026-08-28-omp-18-0-9-admission.md`](../../06-omp-driver/.experiments/2026-08-28-omp-18-0-9-admission.md)
-  (Result item 2) and in [`06-omp-driver/spec.md`](../../06-omp-driver/spec.md)
-  (Channel section, "`ctx = {ui}`"); neither is edited here, because OMP-R05's
-  admission checklist is that subsystem's to amend.
-
-## Follow-up capture: status-line precedence, live (2026-08-29, second run)
-
-The Claude producer section above left the settings precedence it depends on as
-documented-but-uncaptured. It is now measured, and it turns a design risk into a
-hard requirement.
-
-**Method.** Four throwaway project directories, each driven through a real pty
-that auto-accepts the folder-trust dialog, against Claude Code 2.1.250. **No
-`--settings` flag**, so this measures real settings resolution rather than an
-override. The host's `~/.claude/settings.json` declares a `statusLine` running
-the operator's own renderer, which is what the control case proves would
-otherwise render. No paid turns — the status line renders at startup.
-
-| Case | Project files present | Which command ran | Global ran? |
-| --- | --- | --- | --- |
-| local | `.claude/settings.local.json` only | the project's | no |
-| project | `.claude/settings.json` only | the project's | no |
-| both | both files | `settings.local.json`'s — the other marker was never written | no |
-| none (control) | none | the operator's global renderer | yes |
-
-**Result.** Precedence is
-`.claude/settings.local.json` > `.claude/settings.json` >
-`~/.claude/settings.json`. The control establishes these are genuine overrides
-rather than a missing global. The `both` case establishes the winner
-**replaces** the loser outright: only one command runs per render, and the
-losing case's marker file was never written. It is a single slot, not a merge or
-a chain.
-
-**Consequence.** `.claude/settings.local.json` is exactly the file the st2 materializer writes
-for driver-declared agents, so an st2 `statusLine` entry there wins
-unconditionally. Without chaining it silently removes the operator's status line
-on every managed agent — on this host, one that already displays agent id,
-model, context fill, and cost. This is why chaining is specified as a
-requirement (HC-R18) rather than left to the tee's implementation.
-
-The inverse is not solved by chaining: a `statusLine` a human sets in a managed
-agent's `.claude/settings.local.json` is overwritten by st2's own
-materialization of that file, whose merge owns only st2's hook entries. An
-operator's renderer belongs in their own settings, with st2's tee chaining to
-it.
-
-**Limit.** `--settings <file>` also wins and was not compared against the
-project files here; it is not how a managed agent runs.
-
-## Superseded in part (2026-08-29)
-
-Two of this record's conclusions were overtaken the same day by a replay
-benchmark over 90 real sessions,
-[`2026-08-29-write-policy-benchmark.md`](./2026-08-29-write-policy-benchmark.md).
-The harness-signal survey above (the producer arithmetic, the traps, the
-compaction edges, the omp correction) stands unchanged and is still the
-grounding for the producer table. What no longer holds:
-
-- **The movement guard is retired.** This file's write-amplification table
-  measured one synthetic Claude turn and concluded the spike's guard — skip
-  identical, write on a ≥5% move, otherwise at most once per 60 s — was the
-  right policy. Replayed against real sessions it misses 23% of
-  high-occupancy warnings at a 90% threshold and 57% at 94%, and its cost is set
-  by its time floor rather than by its movement clause, so it tracks harness
-  event cadence instead of agent behavior. The spec now specifies fixed 1%
-  quantization plus a compaction edge and a 300 s heartbeat. The reasoning that
-  survives is the part about the *categorical* record's guard: `observe_inner`
-  still cannot express a numeric write policy, which is why the record is a
-  sibling.
-- **The record does not replicate at the path this file recommends** — nor does
-  the shipped `harness-state` — because the replication transport's include list
-  named only `**/resources/**` and `**/status` under an agent directory. The
-  resolution keeps both records where they are and names them in that list
-  instead, so finding 5 above (the delivery watcher's allowlist makes the record
-  inert with no production change) holds exactly as tested here.
-- **The staging file moved out of the agent directory.** The spike's sibling
-  `tmp`-plus-rename is forbidden inside a replicated subtree, where the temporary
-  name becomes a durable replicated key.

-# Choosing the harness-context write policy on replayed sessions
-
-## Question
-
-The placement spike proposed a write guard — skip an identical reading, write on
-a ≥5% window move, otherwise at most once per 60 s — with constants set by
-counting writes in one synthetic Claude turn. Two things were unestablished:
-
-1. **Is that policy right**, measured against real sessions rather than a
-   synthetic turn, and judged on what the record is *for* (would a reader have
-   seen a high-occupancy warning before the agent compacted) rather than only on
-   write count?
-2. **What does a write actually cost** at fleet scale, which is the half
-   [`DQ-H2`](../../05-harness-state/open-questions.md) left open for the
-   categorical record and this record inherits?
-
-## Method
-
-**Corpus.** 45 Codex rollouts (median span 30.6 h, 4,220 readings each, real
-in-protocol windows of 258,400 / 272,000 / 353,400) and 45 Claude transcripts
-(median 21.9 h, 630 readings). Codex occupancy is
-`info.last_token_usage.total_tokens` — `info: null` frames are rate-limit
-updates, not readings. Claude occupancy is `input + cache_creation + cache_read`,
-deduplicated by `message.id` (the same usage is repeated on several JSONL lines
-per API turn, so summing overcounts roughly 2×); `isSidechain` entries and
-subagent transcripts are excluded because they have a different window. Duty
-cycle — time inside a working stretch over wall span — is 27.0% for Codex and
-7.8% for Claude, and writes/hour/agent are reported against that, not against
-active hours.
-
-Claude publishes no window in its transcript, so it is inferred as 200k or 1M
-(the only two shipped) from peak occupancy; 39 of 45 infer 1M and reach a median
-99% of it, which is what confirms the classification. Codex is the
-better-grounded column throughout and is what the conclusions rest on.
-
-**Replay.** Each candidate policy is run over each session's reading series,
-recording every write it would have made. Three metrics: writes per hour per
-agent; time-weighted error, the gap between the true occupancy and the last
-written value as a percentage of the window; and **missed warnings** — the share
-of real compaction events where occupancy truly crossed a threshold but the last
-written value did not. The last is the metric that matches what the record is
-for, and it is swept across thresholds from 80% to 97% rather than fixed at one.
-
-**Local write cost.** 1,000 iterations of the spike's write path (exclusive
-lock, write temporary, rename; no fsync) with a 304-byte record on the real
-catalog filesystem, comparing a temporary staged as a sibling against one staged
-outside the replicated subtree.
-
-**Transport.** Inspection of the fleet's replication configuration and of what
-is actually running on the host.
-
-## Result
-
-### The noise floor rules out "write every distinct reading" as a distinct policy
-
-| \|Δ occupancy\| between consecutive readings, % of window | p50 | p90 | p99 | ≥1% |
-| --- | --- | --- | --- | --- |
-| Codex | 0.15 | 1.51 | 9.19 | 14.8% |
-| Claude | 0.11 | 0.24 | 1.81 | 1.3% |
-
-94.6% (Codex) and 98.4% (Claude) of consecutive readings differ at all, so
-"write every distinct reading" is in practice "write every reading". Re-running
-Codex on prompt-only occupancy gives p90 = 1.58% and an identical ranking, so
-the ≥1% moves are real prompt growth rather than output jitter.
-
-### Cost does not discriminate; accuracy and structure do
-
-| Policy | Codex w/h/agent | Claude w/h/agent | error p95 (cx) | error max | missed @90% (cx) |
-| --- | --- | --- | --- | --- | --- |
-| every reading | 100.7 | 14.8 | 0.00 | 0.0 | 0.0% |
-| turn boundary | 1.8 | 4.6 | 48.76 | 91.4 | 92.1% |
-| movement guard 5% / 60 s (the spike) | 19.2 | 4.6 | 3.43 | 5.0 | 23.1% |
-| movement guard 1% / 60 s | 32.1 | 4.7 | 0.82 | 1.0 | 2.8% |
-| movement guard 5% / 300 s | 10.9 | 1.8 | 4.44 | 5.0 | 29.6% |
-| time-only 60 s | 14.5 | 4.6 | 6.02 | 104.1 | 49.8% |
-| bucket 5% + 300 s heartbeat | 13.1 | 2.2 | 3.80 | 5.0 | 0.0% |
-| bucket 2% + 300 s heartbeat | 23.3 | 2.5 | 1.54 | 2.0 | 0.0% |
-| **bucket 1% + 300 s heartbeat** | **34.1** | **3.2** | **0.76** | **1.0** | **0.0%** |
-
-`DQ-H2`'s recorded failure was 679 writes in 221 s — 3.07 writes/s on a single
-agent, or 11,061 writes/hour/agent. **Every policy in the table is 100–1,000×
-below that**, the most expensive of them at 1/110 of the failure rate. The cost
-axis therefore does not choose between them, which reframes the whole question:
-the guard's constants cannot be justified as cost control.
-
-### Three structural results
-
-**1. A time floor makes cost track the harness, not the agent.** On Claude the
-movement guard at N = 1%, 5%, and 10% with T = 60 s all land at 59 writes per
-active hour — 3600/60. The movement clause is nearly inert; the policy is "one
-write per minute while active". Its cost is therefore set by how often a
-producer speaks, and Codex emits about 25× more readings per hour than Claude,
-so any time-floored policy needs per-harness tuning.
-
-**2. Quantization ties writes to information instead.** Bucket 5% costs 42.5
-writes per active hour on Codex and 7.1 on Claude — a 6× spread that is exactly
-how much faster Codex burns window per active hour, even though it emits 25×
-more readings. Writes per window fill are capped at `100 / N` regardless of
-producer chattiness, which is what makes one constant correct across all five
-harnesses, and which makes the failure `DQ-H2` actually recorded — a producer
-restating per event — structurally impossible rather than merely guarded
-against.
-
-**3. A coarse bucket couples the write policy to the reader's alarm.** A bucket
-write fires on entry to a bucket, so the reader always shares the truth's
-bucket: an alarm on a bucket boundary can never be missed, one between
-boundaries can. Codex missed warnings by threshold:
-
-| Policy | 80 | 85 | 88 | 90 | 91 | 92 | 93 | 94 | 95 | 96 | 97 |
-| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
-| *eligible events n* | *1239* | *1121* | *973* | *821* | *672* | *590* | *436* | *289* | *45* | *18* | *7* |
-| bucket 1% + heartbeat | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
-| bucket 2% + heartbeat | 0 | 3 | 0 | 0 | 8 | 0 | 17 | 0 | 13 | 0 | 0 |
-| bucket 5% + heartbeat | 0 | 0 | 11 | 0 | **51** | **70** | **74** | **79** | 0 | 0 | 0 |
-| movement guard 5% / 60 s | 3 | 6 | 13 | 23 | 35 | 43 | 48 | 57 | 36 | 6 | 0 |
-| movement guard 1% / 60 s | 1 | 1 | 2 | 3 | 4 | 8 | 7 | 22 | 7 | 0 | 0 |
-
-Bucket 5% is excellent at multiples of five and worse than the movement guard at
-91–94%. Only 1% is threshold-agnostic. The denominator shrinks sharply above
-95% — few compactions happen up there — so the flat zeros in the last three
-columns rest on 7–45 events and are not evidence that anything is fine at those
-thresholds; the 91–94% band (n = 289–672) is where the mechanism shows.
-
-Turn-boundary is disqualified outright: 48.8% p95 error, 91.4% maximum, 92.1% of
-warnings missed — the wedge scenario is a single long turn, and this policy is
-silent for its whole duration.
-
-### Two placement findings that outrank any byte count
-
-**Nothing replicates the catalog today.** The catalog is a local filesystem;
-none of the usual replication daemons is running. The intended transport is
-specified in the root spec, but its adoption record is open and states that no
-st2 correctness property may depend on it.
-
-That makes the following the operative results rather than a wire measurement:
-
-- **The spike's path would not replicate at all.** The transport's agent-facing
-  sync includes `**/resources/**` and `**/status` and nothing else under an
-  agent directory. `<agent-dir>/harness-context` matches neither, and
-  **the shipped `harness-state` record has the same defect**, which leaves
-  decision 0006's own "readers read through the catalog they already sync" unmet
-  as written. Resolved by naming both driver records in the include list rather
-  than by moving them (q11): moving would have fixed only the new record, left
-  the shipped one unreplicated, and put driver runtime state on the
-  Resource-binding realization surface.
-- **A staged sibling temporary is explicitly forbidden inside the replicated
-  subtree**, because the transport propagates that name as a real key and
-  restores it after a later local delete. Staging must happen outside the sync
-  root, on the same filesystem so the rename stays atomic.
-
-### Local write cost is negligible either way
-
-| Variant | p50 | p95 | p99 | max | writes/s |
-| --- | --- | --- | --- | --- | --- |
-| temporary as a sibling (the spike) | 0.222 ms | 1.33 | 3.59 | 19.5 | 2,332 |
-| temporary staged outside the sync root | 0.217 ms | 1.71 | 5.98 | 93.0 | 1,464 |
-| sibling plus fsync before rename | 0.620 ms | 5.13 | 21.0 | 96.1 | 514 |
-
-Moving the staging file out is free at p50. One record occupies 4,096 bytes on
-disk regardless of payload. At the recommended policy, 600 agents produce 5.7
-writes/s fleet-wide — 0.13% of one host's single-threaded write capacity, and
-1.9% of the transport's own per-entry coalescing ceiling, so the coalescer never
-engages and each write is one sync.
-
-## Conclusion
-
-Fixed quantization at 1% of the window, plus a compaction edge and a 300-second
-heartbeat, replaces the spike's movement guard. It is the only measured policy
-with zero missed warnings at every alarm threshold from 80% to 97%, its error is
-bounded at one bucket unconditionally, and its write cost is capped by
-construction at 100 writes per window fill regardless of how chatty a producer
-is. The heartbeat is set to the existing state-record refresh interval so this
-record never re-stamps more often than the record beside it.
-
-The movement guard is not merely mistuned: its cost is set by its time floor
-rather than by its movement clause, so it tracks harness event cadence instead
-of agent behavior and would need per-harness constants. Quantization needs one
-constant for all five harnesses for the same structural reason.
-
-Pure quantization is tolerable only because the reader surfaces `ageMs` and
-`stale` instead of deriving an old reading away — quantization alone leaves lag
-unbounded (p95 583 s on Codex, 6,638 s on Claude, and up to 107 h on a parked
-agent), and the heartbeat plus visible age is what makes that honest rather than
-silent.
-
-Separately, and independently of the write policy, the record's path had to
-move: at the spike's location it would not have replicated at all.
-
-## VRS Impact
-
-- Closes the accuracy half of `DQ-C1` and rewrites the spec's write policy:
-  `HARNESS_CONTEXT_BUCKET_PERCENT = 1` and `HARNESS_CONTEXT_HEARTBEAT = 300 s`
-  replace the provisional `HARNESS_CONTEXT_WRITE_FLOOR` and
-  `HARNESS_CONTEXT_MOVEMENT_PERCENT`.
-- Adds HC-R09 (quantized writes, and the reason there is no per-harness knob)
-  and HC-R10 (threshold-agnostic resolution), replacing the earlier guarded-write
-  requirement.
-- Adds HC-R05 (transport-visible placement, a pinned-name test, and staging
-  outside the replicated subtree) and HC-T08 (replication depends on an include
-  list this repository does not own). The record stays at
-  `<agent-dir>/harness-context`; the include list is what changes.
-- Restates HC-T05: the tradeoff is no longer "provisional constants" but
-  "quantization bounds error, only the heartbeat bounds lag, and that is
-  acceptable solely because age is visible".
-- Leaves the transport half of `DQ-C1` open. `DQ-C11` (the same defect in the
-  shipped `harness-state` record) closes with this one, since naming both
-  records in the include list fixes
-  [`05-harness-state`](../../05-harness-state/spec.md)'s record with no
-  migration.
-- Supplies the >100% data point in the record's field rules: 2 of 287,010
-  replayed Codex readings give `used / window` up to 1.041.

-  ([`.experiments/2026-08-29-write-policy-benchmark.md`](./.experiments/2026-08-29-write-policy-benchmark.md)):

-  projects a missing record and an unreadable/malformed/foreign one identically
-  as `null`, which is simpler than the categorical axis and loses the
-  distinction that `driverDiagnostic` deliberately keeps ("absent" is not
-  "indeterminate", and neither reads healthy). For a purely numeric advisory
-  axis the conflation is defensible; for an operator debugging why a runtime
-  reports nothing it is not. Resolves by: either accepting it explicitly with
-  the warning log as the only signal, or adding a status field to the
-  projection.
-- **DQ-C6 History.** The record collapses every compaction into a counter and
-  one timestamp (HC-T02), so "how often did this runtime compact this week" and
-  "how fast does its window fill" are unanswerable. This is the same question
-  observed harness state defers in [`OHS-T03`](../05-harness-state/requirements.md),
-  and it should be answered once for both axes rather than twice differently —
-  the natural shape being events on the agent's built-in stream
-  ([`04-stream`](../04-stream/requirements.md)) with the record as a
-  denormalized projection. Resolves by: a follow-up that specifies history for
-  the categorical and numeric axes together. See [roadmap.md](./roadmap.md).
-- **DQ-C7 Fleet transport cost — folded into `DQ-C1`.** Kept as a pointer so the
-  identifier does not go dangling: the per-sync wire cost of a context write is
-  the open half of `DQ-C1` above, and it is the same measurement
-  [`DQ-H2`](../05-harness-state/open-questions.md) owes the categorical record.
-- **DQ-C8 Supervisor actionability.** HC-A02 makes the record advisory, so
-  nothing may branch on 92% fill today. Making it actionable — nudging a
-  compaction, retiring before a wedge — requires bounded-staleness semantics for
-  a *remote* reader, which is exactly
-  [`DQ-H5`](../05-harness-state/open-questions.md), still unmet and one of the
-  reasons decision 0006's spec ships Draft. Resolves by: `DQ-H5` first, then a
-  separate decision defining the action vocabulary.
-- **DQ-C9 Subagent context is invisible.** Claude's status-line payload
-  describes the top-level session; a subagent's own window is not in it (there
-  is a sibling `subagentStatusLine` slot, unexamined), and hook events carrying
-  `agent_id` are excluded from top-level state by both producers — the
-  categorical one, and now the numeric one's compaction edges. So a runtime whose
-  subagent is saturating reports the parent's fill, and a subagent's compaction is
-  not counted against it.
-  Whether that matters depends on whether subagents are where saturation
-  actually happens on this fleet. Resolves by: a capture of the subagent status
-  line, and a decision about whether one record per agent is the right grain.
-- **DQ-C10 OpenCode multi-session aggregation.** The categorical producer
-  aggregates across all of the server's sessions (any busy session is activity),
-  because that projection composes. Occupancy does not: two live sessions have
-  two windows and one record. The spec's producer row describes reading the last
-  non-summary assistant message without saying whose session it belongs to.
-  Resolves by: deciding between the most recently observed session (matching
-  where delivery targets), the fullest window, or a per-session shape this
-  record does not have.
-- **DQ-C11 `harness-state` has the same placement defect — resolved 2026-08-29
-  with this subsystem's own.** Both driver records sit at the agent-directory
-  root and matched none of the replication transport's include globs. The
-  resolution names them in that list (`**/harness-state,**/harness-context`)
-  rather than moving either, so the shipped record is fixed without migrating a
-  live record and
-  [decision 0006](../.decisions/0006-observed-harness-state-is-a-driver-written-catalog-record.md)'s
-  "readers read through the catalog they already sync" holds again. The include
-  list is fleet-side; st2's obligation is the pinned-name test in HC-R05.
-- **DQ-C12 A driver runtime record under the resource directory — withdrawn.**
-  The question only existed while the record was to be moved under `resources/`
-  to satisfy the include globs. It stays at the agent-directory root, so no
-  driver record lives on the Resource-binding realization surface and the
-  tension does not arise.
-- **DQ-C13 The status-line tee's telemetry cadence — resolved 2026-08-29 by
-  measurement and a rule.** Claude's `refreshInterval: 5` makes the tee ~720
-  short-lived `st2` processes per hour per seat, and Claude waits for each to
-  exit. Measured against a bound-but-never-accepting local collector: a tee that
-  initializes telemetry takes **5.009 s** on the path that logs a warning — the
-  logger provider's final `force_flush` — while `st2 driver claude-observe`, on
-  the same endpoint, takes **10.022 s**. With no pipeline built, both paths
-  return in **0.010–0.061 s**. So an unreachable collector would have stalled
-  every render past Claude's own 5-second refresh, permanently.
-
-  The resolution is that `st2 driver claude-statusline` does not initialize the
-  telemetry pipeline at all (`Telemetry::local_only`): stderr diagnostics, no
-  exporters, no global providers, nothing to flush. The rule is stated in
-  [`06-observability/spec.md`](../06-observability/spec.md) as **cadence, not
-  hook class** — `claude-observe` is event-driven and stays instrumented, exactly
-  as that spec names it, so this is an exemption with an argument rather than a
-  blanket carve-out. The tee's own `hook_invocations_total` call was removed with
-  it: a metric that provably cannot record is worse than none, because it reads
-  as instrumentation.
-
-  Proved by `tests/claude_statusline.rs::the_tee_never_reaches_for_a_collector_even_when_it_has_something_to_report`,
-  which drives the recording-FAILURE path on purpose — the happy path emits no
-  `tracing` event, so it has nothing to flush and stays fast even with a pipeline
-  built. A first version of that test drove only the happy path and passed
-  against the unfixed binary; that is the trap this entry exists to record.

-# Harness context requirements
-
-**Status:** Accepted — confirmed by Johannes on 2026-08-29
-
-## Context
-
-This subsystem defines the **harness context record**: the driver-written
-numeric record of how full an agent's harness context window is, how often that
-harness has compacted, and the adjacent facts the same channel carries (model,
-harness-reported session cost, harness-reported rate limits, cumulative session
-tokens). It is a sibling of
-[observed harness state](../05-harness-state/requirements.md), which owns the
-categorical axis (`state`, `blockedOn`, `ask`, `inputBuffer`) and keeps its own
-fencing, freshness, and derivation rules. Where this file and
-[`05-harness-state`](../05-harness-state/requirements.md) or the
-[root requirements](../requirements.md) disagree, they win and this file is
-wrong.
-
-The motivation is the context-saturation failure mode: an agent runtime that
-fills its window and compacts (or wedges) with nobody watching. Nothing in the
-fleet detects it today — dotfiles' Claude hook chain maps `PreCompact` to a
-transient `status=compacting` PTY event and persists nothing, tokenlens records
-a retrospective `compaction_count` from transcripts and has no context-window
-column at all, and no st2 supervisor, reconcile, or flapping path reads any
-harness record.
-
-Provider-specific arithmetic belongs to harness drivers, exactly as
-[`OHS-R05`](../05-harness-state/requirements.md) assigns categorical
-classification to them: st2 core owns the envelope, its guard, its freshness,
-and its exposure. The record-shape and placement decisions are recorded in
-[`.decisions/0014`](../.decisions/0014-harness-context-is-a-sibling-numeric-record.md).
-Delivery gating is not this subsystem's concern and no delivery path reads this
-record.
-
-## Assumptions
-
-- **HC-A01 Every maintained harness publishes its own fill number:** each of the
-  five drivers has a positive channel carrying occupancy — Claude's `statusLine`
-  stdin payload, Codex's `thread/tokenUsage/updated` app-server notification,
-  pi's and omp's `ctx.getContextUsage()` inside the injected extension, and
-  OpenCode's `message.updated` SSE frame joined with a `GET /config/providers`
-  pull. Where a channel yields no number the driver writes nothing, and the
-  absence of a record is honest ("never observed"), never a fabricated zero.
-- **HC-A02 Advisory surface:** consumers are humans, a roster, a TUI, and
-  Doctor. The record authorizes nothing: no delivery, no lifecycle action, no
-  reconciliation, and no supervisor branch. A wrong-but-fresh number can mislead
-  an operator; it cannot misdeliver a message or end a runtime. This mirrors
-  [`OHS-A02`](../05-harness-state/requirements.md) deliberately — supervisor
-  actionability is a separate decision that must first settle
-  [`DQ-H5`](../05-harness-state/open-questions.md).
-- **HC-A03 Trusted writers:** the record is unauthenticated catalog state under
-  the trusted-fleet model (root `A02`). The writers are the owning session's
-  driver processes — the wrapper, its channel, and the hook or status-line
-  subprocesses it shares its incarnation token with; nothing verifies that
-  claim.
-- **HC-A04 No single formula reproduces five harnesses:** measured 2026-08-29,
-  every harness computes "context used" differently — different numerator
-  (last-response total vs prompt-only input vs an st2-computed join),
-  different denominator (a raw window vs a window with a fixed baseline
-  subtracted), and different display rounding. An st2-normalized number would
-  disagree with what the operator sees in the harness's own UI, and that
-  disagreement is the first thing a human files as a bug.
-
-## Acceptable Tradeoffs
-
-- **HC-T01 Percent is an operator view, not a physical quantity:** because
-  `usedPercent` is harness-native (HC-A04), comparing it across harnesses
-  compares "what each operator would see", not one measured ratio. The record's
-  `harness` field is what tells a reader which arithmetic produced the number;
-  the per-harness rule is stated in the spec's producer table.
-- **HC-T02 No history in v1:** the record carries a compaction counter and one
-  timestamp, so a second compaction overwrites the first's detail. Per-event
-  history is deferred, not deleted, and is expected to be settled together with
-  observed harness state's deferred transition history
-  ([`OHS-T03`](../05-harness-state/requirements.md)) rather than separately.
-- **HC-T03 Version-coupled constants:** Codex's 12,000-token baseline and omp's
-  input-only `tokens` semantics are properties of a specific harness build, not
-  of a documented API contract. v1 accepts that a harness bump can silently
-  change what the number means, bounded by a per-harness fixture test pinned to
-  the verified version (HC-R13) under the omp version-gate discipline
-  ([`OMP-R05`](../06-omp-driver/requirements.md)).
-- **HC-T04 Numbers are unfenced:** the record carries no ownership sequence, no
-  written claim, and no floor sidecar. A straggler from a superseded session can
-  land a reading; all it says is "this number is older than you think", which
-  the record's own origin timestamp already says, and the next reading
-  overwrites it. This is the deliberate difference from
-  [`OHS-R01`](../05-harness-state/requirements.md)'s fenced envelope, whose
-  machinery exists to stop a straggler resurrecting a *live state* — a
-  dangerous lie a stale number cannot tell.
-- **HC-T05 Lag is bounded only by the heartbeat:** quantization bounds *error*
-  unconditionally (a reading is never more than one bucket away from the truth)
-  but leaves *lag* unbounded on its own — an agent that stops consuming window
-  stops crossing buckets. The heartbeat is what bounds lag, and between
-  heartbeats a reader may hold a reading several minutes old. This is tolerable
-  only because the reader surfaces age rather than hiding it (HC-R06): unbounded
-  lag is reported, not silent. If the age projection were ever dropped, this
-  tradeoff would no longer hold and the policy would need a time floor.
-- **HC-T08 Replication depends on a list this repository does not own:** the
-  transport's include list lives in the fleet's own configuration, so st2 can
-  publish a record it believes is replicated while the other side does not carry
-  it. Nothing errors when that happens. v1 accepts the split ownership — the
-  alternative, contorting the record's location to match a glob written for
-  other purposes, buys nothing a named include entry does not — bounded by
-  st2-side test that pins the names it expects (HC-R05), and by the fact that no
-  correctness property here depends on the transport at all: everything works
-  with no replication, and remote visibility is what is lost. Both records are
-  published mode `0600` — as is every record st2's shared publication primitive
-  writes, though not the bus message files, which stay at the writing process's
-  umask — so a transport reading the catalog as a different unprivileged uid
-  needs that decision taken deliberately rather than inherited from a default.
-  No such transport runs today, which is also what leaves the wire-cost half of
-  `DQ-C1` unmeasured.
-
-## Requirements
-
-### Must publish one numeric envelope
-
-- **HC-R01 Context envelope:** each agent has at most one harness-context
-  record, `<agent-dir>/harness-context`, schema `st2.harness-context.v1`,
-  written only by the owning session's driver processes under its own lock, and
-  replaced atomically. It carries the fill
-  triple
-  (`usedTokens`, `windowTokens`, `usedPercent`), the compaction triple
-  (`compactions`, `lastCompactionMs`, `lastCompactionTrigger`), the observing
-  harness, an origin timestamp, and the adjacent facts of HC-R16. Reads are
-  additive-tolerant: a reader may be older than its writer, and unknown future
-  enum words decode as indeterminate, never as a definite value.
-- **HC-R02 Harness-native fill:** `usedPercent` is the number the harness itself
-  displays to its operator, computed by that harness's own rule; `usedTokens`
-  and `windowTokens` are the harness's own operands. A producer that cannot
-  obtain a window withholds `usedPercent` rather than dividing by a table, an
-  estimate, or a default. The value is carried raw and is never clamped by a
-  producer or a reader — occupancy above 100% of the window is observed in
-  practice and is precisely the condition worth surfacing; clamping belongs to
-  whatever renders it.
-- **HC-R03 Withheld, never fabricated:** where a harness positively reports that
-  it does not know its own occupancy — pi after a compaction, Claude before the
-  session's first API response — the producer withholds the value. No path
-  substitutes zero, the previous reading, or a derived estimate for a
-  harness-declared null.
-- **HC-R04 Transport-safe freshness:** freshness lives in the record bytes: an
-  embedded origin timestamp with its own staleness and future-skew constants,
-  deliberately not aliases of the presence or harness-state constants. No read
-  path consults file mtime, and every landed write is byte-distinct so a
-  transport that carries content but not metadata always carries a refresh.
-
-- **HC-R05 Transport-visible placement:** the record must be carried by the
-  catalog's replication transport, and every temporary, partial, or staged file
-  the writer produces must live **outside** the replicated subtree. Both
-  failures are silent: a record the transport does not carry is invisible to
-  exactly the remote readers a catalog record exists for, and a staged temporary
-  name inside the replicated subtree becomes a durable replicated key that is
-  restored after a later local delete. The record's own location stays beside
-  `harness-state` at the agent-directory root, where the driver records belong;
-  it is the transport's include list that names them, so this requirement is met
-  by the two sides agreeing on that list rather than by moving the record. st2's
-  side of that agreement is pinned by a test asserting the exact record names it
-  expects the transport to carry, so a rename here cannot silently stop
-  replicating.
-
-### Must stay readable when the categorical axis is not
-
-- **HC-R06 Stale readings are returned, not derived away:** past the staleness
-  horizon a reader returns the reading it found, marked `stale` and carrying its
-  derived age. There is no `unknown` vocabulary on this axis: an old number with
-  a visible age is more useful to the operator this record exists for than an
-  absence, and it cannot mislead a lifecycle action (HC-A02).
-- **HC-R07 Independent of observed state:** the numbers survive every state the
-  categorical record can derive. An `observedState` of `unknown` — stale,
-  session-dead, malformed, or a fresh claim placeholder — does not blank, hide,
-  or invalidate the context reading, because the wedge case this record exists
-  for is exactly an agent runtime whose state has gone indeterminate at 190k of
-  a 200k window.
-
-### Must never wake what it informs
-
-- **HC-R08 No delivery wake:** a write to the harness-context record wakes no
-  delivery pump, no reconciliation pass, and no watcher owned by its own writer.
-  Delivery pumps watch by allowlist — the `resources/inbox` subtree and the
-  presence record — and the record is a sibling of neither, so it is ignored
-  with no production change.
-
-### Must bound its own write rate
-
-- **HC-R09 Quantized writes:** a reading is written when it enters a different
-  bucket of the window, when a compaction occurs, or when the record is older
-  than a named heartbeat interval — whichever comes first. The bucket width and
-  the heartbeat are named constants. Quantization is required over a
-  time-floored movement guard because it ties write cost to *information*
-  rather than to producer chattiness: writes per window fill are capped at
-  `100 / bucket-percent` no matter how often a harness emits a reading, so no
-  future producer can inflate the write rate by restating, and no per-harness
-  tuning is needed.
-- **HC-R10 Threshold-agnostic resolution:** the bucket width is chosen so that a
-  reader's value always shares the truth's bucket at every alarm threshold, not
-  only at multiples of the bucket width. A policy whose accuracy depends on
-  where a future consumer sets its alarm couples the write policy to that
-  consumer; this requirement forbids that coupling.
-
-### Must be produced by every maintained harness
-
-- **HC-R11 All-harness coverage:** Claude, Codex, pi, omp, and OpenCode each
-  ship a producer. Each producer's numerator, denominator, percent rule, and
-  withholding conditions are stated per harness in the spec; a harness with no
-  producer would leave its declarations reading `null` indefinitely and
-  re-create the two-tier observability this record exists to close.
-- **HC-R12 Compaction accounting:** the record carries a compaction count, the
-  time of the last compaction, and a trigger drawn from the closed vocabulary
-  `manual | auto | threshold | overflow | idle | unknown`. The spec names, per
-  harness, which edge produces the count, which trigger words that harness can
-  yield, and whether the count is scoped to the session incarnation or is
-  harness-durable across restarts.
-- **HC-R13 Version-pinned producer fixture:** each producer's arithmetic is
-  proved by a fixture captured verbatim from the named harness version, and the
-  version is asserted in the test. A harness bump that changes the numerator,
-  the denominator, or a magic constant must fail that fixture rather than
-  silently publish a differently-meaning number.
-
-### Must be readable beside the other axes
-
-- **HC-R14 Roster join:** `st2 agents --json` carries `context` as a fourth
-  independent top-level axis beside `status`, `observedState`, and
-  `driverDiagnostic`, always emitted and `null` when no record exists, following
-  the roster's existing null convention. It never rewrites presence, desired
-  lifecycle, observed state, or `lastActivity`. The pinned roster wire
-  assertions and the *Stable roster JSON* invariant wording change deliberately,
-  in the same change, with the new proof named.
-- **HC-R15 Session-boundary reset:** the relaunch claim that supersedes the
-  harness-state record also removes the harness-context record, so a new
-  incarnation reads "no context yet" rather than the previous incarnation's
-  fill. `incarnation` is carried in the record as provenance — evidence of which
-  session produced a number — and is never consulted as a fence.
-- **HC-R16 Adjacent facts, one owner each:** where the same channel supplies
-  them, the record carries the model identifier, the harness-reported cost at
-  the scope the harness reports, stated per harness in the spec producer table,
-  the harness-reported account rate limits, and the cumulative session token
-  total. Each is carried as what the harness reported and nothing more; absent
-  facts are `null`, never zero. The cumulative total is named so it cannot be
-  mistaken for occupancy, and it is never the numerator of any percent.
-- **HC-R17 Doctor advisory:** Doctor surfaces a warning for an agent it owns
-  when the reading is at or above a named st2 warning threshold, and when the
-  record is stale beside a `running` desired state. Both are advisory output and
-  neither ever changes Doctor's exit status, matching how Doctor already treats
-  the categorical axis (`OHS-R10`). The threshold is st2's own number for "worth
-  a human's attention", explicitly **not** a prediction of where the harness will
-  compact — that point is harness-, model-, and setting-specific, and a number
-  claiming to know it would be wrong in both directions.
-- **HC-R18 The status-line tee must chain:** where st2 occupies a harness's
-  single status-line slot to read a producer channel, it must invoke the
-  operator's own renderer and pass the payload on. The slot is single-valued and
-  the highest-precedence declaration replaces the others outright — nothing
-  merges — so occupying it without chaining silently removes whatever the
-  operator had, on every managed agent, with no warning. Where no downstream
-  renderer resolves, and wherever a resolved renderer fails, the tee writes
-  nothing to stdout: the degraded case is an EMPTY status line, and its
-  diagnostic goes to stderr, which the harness does not render. Silence is
-  required rather than merely permitted, because the payload on that channel is
-  machine-readable JSON — session id, transcript path, model and usage blocks —
-  and a slot that echoes it paints that JSON across the operator's terminal at
-  the refresh cadence. That is strictly worse for them than a blank row and
-  carries nothing they can act on, so "transparency over silence" is the wrong
-  trade for this surface even though it is the right one for a channel a human
-  reads. Which arm runs never affects recording; only the human-facing line is
-  at stake. The inverse also holds and is not solved by chaining: a renderer a
-  human sets in a file st2 materializes is not preserved by st2's merge, which
-  owns only its own hook entries.

-# Harness context roadmap
-
-Non-normative. This file records the direction this subsystem is expected to
-move in, so that v1's deliberate simplifications read as choices rather than
-oversights. Nothing here is a commitment, and nothing here constrains
-[spec.md](./spec.md) — where the two differ, the spec is what st2 does.
-
-## Where v1 stands
-
-v1 is a **denormalized snapshot**: one record per agent, overwritten in place,
-quantized so it writes on information rather than on every reading, carrying the
-last reading and a compaction counter. Every consumer polls the roster to read it. That shape was
-chosen because it is small, because it composes with the two records already
-beside it, and because the guard makes its write rate bounded and explainable.
-
-Its costs are known and stated as tradeoffs, not defects: readings between
-bucket crossings are lost, bounded at one bucket of error (HC-T05), the compaction detail of
-everything but the last event is gone (HC-T02), and a reader learns about a
-change only when it next polls.
-
-## Direction: readings and compactions as events, the record as a projection
-
-The lossiness is the part worth undoing first. Both signals this subsystem
-carries are naturally *edges* — a reading was taken at a time, a compaction
-happened at a time — and st2 already has a durable record kind for edges: the
-agent's built-in stream
-([`04-stream`](../04-stream/requirements.md),
-[decision 0004](../.decisions/0004-stream-events-are-a-distinct-record-kind.md)).
-A design where the producer appends an event and the harness-context record
-becomes a denormalized projection of the fold would be less lossy and closer to
-real time, and it would make the guard a projection-update policy rather than an
-information filter.
-
-Two things stand between here and there, and neither is cheap:
-
-- The hook-process producers (Claude's status-line tee, its compaction hooks)
-  are short-lived subprocesses with no stream-append plumbing today.
-- Stream direction today is ingress *into* an agent, not egress *about* one —
-  the reason decision 0006 rejected the same idea for the categorical axis.
-
-So the event-driven design is a direction, not a deferred implementation: it
-becomes tractable if and when egress streams exist, and it should be revisited
-then rather than approximated now.
-
-## Direction: history, once, for both axes
-
-`DQ-C6` and [`OHS-T03`](../05-harness-state/requirements.md) are the same
-question asked twice. Answering it once — a history of state transitions and of
-context readings on one mechanism — buys what neither axis can answer alone:
-histograms of token growth per turn, time-to-first-compaction, whether a runtime
-that compacts often is also one that idles blocked. Answering it twice would
-give the fleet two incompatible histories to join.
-
-## Direction: supervisor actionability
-
-The record is advisory by decision (HC-A02), and the gate is not this
-subsystem's to open: a remote supervisor acting on a number needs the
-bounded-staleness semantics [`DQ-H5`](../05-harness-state/open-questions.md)
-still owes both axes. If that lands, "nudge a compaction before the window
-wedges" becomes a real option and needs its own action vocabulary, its own proof
-that a stale reading is a hard no-op, and its own decision record.
-
-## Direction: a metrics feed through tokenlens, not through st2
-
-Fleet-scale questions ("how much of the fleet is above 80% fill right now") want
-a metrics pipeline, not a roster poll. The constraint is already written down:
-[`OHS-R15`](../05-harness-state/requirements.md) and `O11Y-R09` forbid agent,
-runtime, session, and message identity in metric labels, so per-agent fill can
-never be a label — only histograms and fleet aggregates.
-
-tokenlens is the natural exporter and already the fleet's registered token and
-cost producer, with a `compaction_count` derived retrospectively from
-transcripts and a Grafana dashboard in place; it has no context-window column
-today and lists context replay as future work. The reconciliation problem to
-solve first is that a live st2 counter and a transcript-derived tokenlens
-counter are two sources of truth for the same quantity. That is a tokenlens-side
-design, not an st2 record change.
-
-## Direction: consumers
-
-The roster wire is the contract; the interesting consumer is a TUI row. Nothing
-in the fleet renders token or context information today. A numeric column beside
-uptime and inbox count is an additive change on the consumer side — a new
-*state* would need enum, glyph, and legend entries, a number would not — and
-pinned consumers already ignore unknown keys, so the axis can land before any of
-them read it.

-# Harness context specification
-
-This document specifies the harness-context record, its guard, its per-harness
-producers, and its roster exposure. It builds on
-[requirements.md](./requirements.md). The categorical observation axis remains
-in [`05-harness-state/spec.md`](../05-harness-state/spec.md) and reads none of
-this; declared presence remains in the root spec's R08 section.
-
-## Status
-
-Partially implemented. The core is in the tree as of 2026-08-29: the record and
-its schema, the quantized write guard, the reading projection, the roster's
-fourth axis, the session-boundary removal, the Doctor advisory, and the pinned
-replicated-record names — `src/harness_context.rs`, with the invariant rows
-*Harness context discipline* and *Replicated-path discipline* naming their
-proofs.
-
-**All five producers ship: claude, codex, pi, omp, and opencode.** The
-status-line tee (HC-R18), the Claude fill arithmetic, and its compaction
-accounting are in the tree as of 2026-08-29 — `hooks/claude-statusline.sh`,
-`st2 driver claude-statusline`, and the `PreCompact`/`PostCompact`
-registrations, with the invariant row *Status-line slot chaining* naming their
-proofs. The codex app-server pump writes the record from
-`thread/tokenUsage/updated` and counts compactions off the `contextCompaction`
-thread item — `src/codex_app_server.rs`. The pi and omp rows share one extension
-path in `hooks/pi-channel.ts` and `hooks/omp-channel.ts`, consumed by
-`src/pi_channel.rs`. The opencode row joins SSE `message.updated` with
-`GET /config/providers` in `src/opencode_session.rs`. Each producer writes
-beside the harness-state writer its wrapper already owned and under the same
-incarnation, and every row is version-pinned by an HC-R13 fixture over a
-verbatim capture, so HC-R11 is met: a declaration on any of the five harnesses
-publishes a non-`null` `context`.
-
-The placement, guard, and Claude producer were first built as a throwaway spike
-([`.experiments/2026-08-29-context-signals-and-write-placement.md`](./.experiments/2026-08-29-context-signals-and-write-placement.md)),
-and the spike's tree is not the shipping tree. The write policy is no longer
-provisional: it was chosen on a replay benchmark over 90 real sessions
-([`.experiments/2026-08-29-write-policy-benchmark.md`](./.experiments/2026-08-29-write-policy-benchmark.md)),
-which also moved the record's path. The Claude producer's status-line renderer
-contract with dotfiles closed on 2026-08-29 (`DQ-C2`, dotfiles PR #2160). The
-one residual that remains is the transport half of `DQ-C1`, unmeasurable until a
-transport runs. Open questions are tracked in
-[open-questions.md](./open-questions.md); the direction this design deliberately
-does not take yet is in [roadmap.md](./roadmap.md).
-
-The `agent` field's immutable-ID meaning is the accepted target, and it ships
-as a new record version, `st2.harness-context.v2`: the version suffix is the
-read contract, so changing an existing field's meaning reserves the next
-version rather than reusing `v1`. Records and producers stay on
-`st2.harness-context.v1`, whose `agent` remains a bus identity, until
-[DELTA-003](../.delta/DELTA-003-agent-address-not-implemented.md) closes.
-Version 2 is otherwise identical to the shape below, and the reader-first
-rollout accepts both versions before any version-2 writer activates.
-
-## Scope
-
-This specification defines the harness-context record, its freshness and
-staleness projection, its write guard, the five per-harness producers and their
-version-coupled arithmetic, compaction accounting, session-boundary behavior,
-and the roster exposure. It does not define: the categorical observation axis or
-its fencing ([`05-harness-state`](../05-harness-state/spec.md)); per-compaction
-history or a context event stream (deferred, HC-T02, `DQ-C6`); idle or
-idle thresholds, escalation, or
-notification policy beyond Doctor's advisory line (root `R20`); the fleet
-metrics feed (`06-observability`, roadmap); and any
-supervisor action taken on a number (HC-A02, `DQ-C8`).

-
-The three records are independent axes on one agent directory. The context
-record's numbers stay readable when the state record derives `unknown`
-(HC-R07), and the state record's fencing does not extend to them (HC-T04).
-
-## Schema identifiers
-
-`st2.harness-context.v1` follows the repository-local convention the presence,
-harness-state, and driver-diagnostic records already use: `st2.<record-kind>.vN`,
-lowercase, dot-separated, where `<record-kind>` is the record's file name. The
-namespace is st2's own and is not registered anywhere; st2 core is its steward.
-The version suffix is the read contract, not the field set: additive fields do
-not bump it, and a reader that finds any other schema string refuses the record
-rather than guessing at fields spelled like this version's. Examples: valid
-`st2.harness-context.v1`; the reserved immutable-ID shape
-`st2.harness-context.v2`, which tolerant readers accept before any producer
-emits it; foreign and therefore refused `com.example.harness-context.v1`;
-invalid (no version) `st2.harness-context`.
-
-## Record (HC-R01, HC-R04)
-
-One JSON object at `<agent-dir>/harness-context`, beside `harness-state`,
-written under its own lock `.harness-context.lock`, newline-terminated, and
-replaced atomically by a rename from a staging file held **outside** the
-replicated subtree (see
-[Placement and transport](#placement-and-transport-hc-r05)):
-

-
-Field rules:
-
-- `harness` is the discriminator for the arithmetic. There is deliberately no
-  second `semantics` field: one discriminator for one semantic axis, and a
-  reader that knows the harness knows which producer row of the table below
-  produced the number. A `harness` this reader does not recognize makes the
-  numbers uninterpretable, so the record reads as absent.
-- `usedTokens`, `windowTokens`, and `usedPercent` are independently optional and
-  each is `null` when withheld (HC-R02, HC-R03). `usedPercent` present with
-  `windowTokens` absent is legal — Claude publishes its own integer percent
-  alongside a window it may not yet have populated — but `usedPercent` is never
-  computed by st2 from a window st2 guessed.
-- `usedPercent` may exceed 100, and readers must handle that rather than assume
-  a 0..100 range. pi and omp report a float that runs above 100 when a turn
-  overruns the window (585.6% measured in the pi lab against a 4,000-token
-  window). Claude clamps to 0..100 itself. Codex's *operands* are not clamped —
-  2 of 287,010 replayed Codex readings give `used / window` up to 1.041 — but
-  the shipped Codex producer mirrors Codex's own function rather than dividing
-  the operands, and that function floors `remaining` at zero, so those readings
-  reach the record as a saturated 100 rather than as 104. The overrun is lost
-  inside the harness's arithmetic, before st2 sees it; the harnesses that can
-  publish above 100 are the ones publishing a float of their own. **The record
-  carries the raw value and never clamps it**: a reading above 100 is a real
-  observation of an overrun, and clamping at the producer would hide exactly the saturation this
-  record exists to show. Clamping is a *display* concern — a consumer rendering
-  a bar or a percentage clamps for its own layout, and does so knowing it is
-  discarding information the record deliberately kept.
-- `sessionTotalTokens` is cumulative lifetime spend for the session and is
-  **never** occupancy. It is named for that distinction (HC-R16): a measured
-  Codex session read 2,235,329 cumulative against a 258,400-token window, so a
-  consumer dividing it by `windowTokens` reports >800%.
-- `costUsd` is the harness-reported cost at the scope the harness reports, in
-  the harness's own accounting; no st2 path recomputes or reconciles it. Claude
-  and OpenCode report session totals; pi and omp report the last assistant
-  message's per-message figure; the producer table names each source. Codex
-  reports none, so the field is `null`. A consumer comparing this field across
-  harnesses must read the `harness` discriminator first.
-- `rateLimits` is harness-reported and account-scoped (HC-T06). It repeats
-  across every agent runtime sharing an account. Absent windows are `null`.
-  Its optional `observedAtMs` records the quota observation independently of
-  context occupancy. Claude's status line repeats an in-memory quota snapshot
-  without a fetch timestamp: the writer preserves the snapshot's first observation
-  time until its values, resets or account change. Codex records the time of its
-  `account/rateLimits/updated` notification and preserves it through later token
-  readings. Compaction and context heartbeats preserve this time too. Older
-  records fall back to the outer `observedAtMs`; the first upgraded write preserves
-  that old time when the limits are unchanged.
-- `lastCompactionTrigger` is a closed union, additive-tolerant on read: an
-  unrecognized future word decodes as `unknown`, never as a definite trigger.
-  `unknown` is a legitimate v1 value for three of the five harnesses.
-- `incarnation` is the writing session's token, carried as provenance only
-  (HC-R15). Nothing refuses a write on it, no sequence accompanies it, and there
-  is no floor sidecar. A reader may use it to tell "this number came from the
-  session currently running" from "this number predates it"; that is its whole
-  purpose.
-- `observedAtMs` is when the reading was taken, not when the file was written,
-  and is never re-stamped without a new reading behind it. A producer holding no
-  fresh reading does not write at all, so the record ages rather than looking
-  refreshed — see the heartbeat rule in the write policy.
-- `writtenAtMs` is when the record was written, and is strictly monotonic per
-  record. **Added during implementation** (2026-08-29), additively and therefore
-  without a version bump. The two stamps answer different questions and
-  collapsing them is wrong in a way that shows up immediately: the write
-  policy's heartbeat clause asks how old the *record* is, while `ageMs` asks how
-  old the *reading* is, so a producer that writes at T carrying a reading taken
-  at T−4min would look four minutes stale against a five-minute heartbeat and
-  re-publish almost at once. Monotonicity is also what keeps HC-R04's
-  byte-distinctness intact against a same-millisecond predecessor. Readers
-  derive nothing from it: `ageMs` and `stale` come from `observedAtMs` alone.
-- `usedPercent` and the other fractional fields are JSON numbers, so an integral
-  reading may serialize as `33.0` rather than `33`. That is the cost of carrying
-  pi's and omp's floats (585.6 was measured) in one field, and it is
-  numerically identical to a consumer.
-- Deserialization is additive-tolerant (no strict unknown-field rejection).
-
-Constants, deliberately not aliases of the presence or harness-state constants
-(HC-R04):
-
-| Constant | Value | Meaning |
-| --- | --- | --- |
-| `HARNESS_CONTEXT_STALE` | 60 min | past this age a reading is returned marked `stale` |
-| `HARNESS_CONTEXT_FUTURE_SKEW` | 60 s | beyond this the clock is untrusted and the record reads absent |
-| `HARNESS_CONTEXT_BUCKET_PERCENT` | 1 | window fraction that defines a write bucket |
-| `HARNESS_CONTEXT_WARN_PERCENT` | 80 | at or above this reading Doctor emits an advisory; st2's own attention threshold, not a compaction prediction |
-| `HARNESS_CONTEXT_HEARTBEAT` | 300 s | maximum interval between writes while a reading is available; independent of the categorical `HARNESS_STATE_REFRESH` cadence |
-
-An idle seat with unchanged numeric readings can show older “observed N s ago”
-values between these five-minute refreshes. Numeric bucket, account/reset,
-rate-limit and compaction changes still publish immediately.
-
-The 60-minute horizon is four times harness-state's 15-minute one on purpose: a
-categorical state that is an hour old is a dangerous claim about what an agent
-is doing right now, while a token count that is an hour old is a still-useful
-lower bound on how full a window has become.
-
-## Reading (HC-R06, HC-R07)
-
-What a reader projects, in evaluation order:
-
-| Evidence | Projects as | Reason |
-| --- | --- | --- |
-| No record file | `null` | never observed |
-| Unreadable, unparseable, or a `schema` outside the accepted versions | `null`, warning logged | nothing trustworthy to report; `DQ-C5` asks whether this deserves an explicit `indeterminate` the way `driverDiagnostic` has one |
-| Unrecognized `harness` | `null`, warning logged | the arithmetic is unknown, so the numbers have no meaning |
-| `observedAtMs` > now + `HARNESS_CONTEXT_FUTURE_SKEW` | `null` | a clock this wrong makes the derived age meaningless |
-| `observedAtMs` ≤ now − `HARNESS_CONTEXT_STALE` | the reading, `stale: true`, with `ageMs` | HC-R06: returned with its age, never derived away |
-| Otherwise | the reading, `stale: false`, with `ageMs` | — |
-
-The accepted versions are `st2.harness-context.v1` and, once tolerant readers
-ship, `st2.harness-context.v2`; any other schema string is refused.
-
-`ageMs` is derived by the reader from `observedAtMs`; no read path consults file
-mtime. There is no `unknown` vocabulary on this axis and no path from any
-absence to a fabricated number.
-
-The projection is computed independently of the harness-state record. It is not
-consulted by, and does not consult, the state derivation: an agent whose
-`observedState` reads `unknown` for any of that record's nine reasons still
-reports its last context reading with the age it has (HC-R07).
-
-## Write policy (HC-R09, HC-R10)
-
-```text
-reading arrives
-   |
-   +-- compaction edge?                                  -> write
-   +-- floor(used / (BUCKET_PERCENT% of window)) changed

-   +-- otherwise                                          -> skip
-```
-
-Fixed quantization at 1% of the window — 100 buckets — plus a compaction edge,
-a bounded Claude exhaustion/reset edge, and a 300-second heartbeat. Codex
-account-window occupancy does not classify availability because Codex can
-continue through credits and this record does not carry the credit metadata
-needed to prove otherwise. The heartbeat fires only when the producer holds a
-reading taken since the last write: it re-publishes a *fresh* reading whose
-bucket happens not to have changed, and never re-stamps a stale one. A producer
-with no new reading writes nothing at all, and the record ages visibly through
-`ageMs` instead. This is what keeps HC-R04's byte-distinctness rule intact — a
-write that changed nothing would carry no refresh across a transport that
-compares content — and it is why the constant is described as the maximum
-interval between writes *while a reading is available*. The policy was chosen on a replay benchmark over 45
-Codex rollouts (median span 30.6 h, 4,220 readings each, real in-protocol
-windows) and 45 Claude transcripts
-([`.experiments/2026-08-29-write-policy-benchmark.md`](./.experiments/2026-08-29-write-policy-benchmark.md)).
-
-### Why not a movement guard with a time floor
-
-The spike's candidate — skip identical, write on a ≥5% move, otherwise at most
-once per 60 s — is dominated, and the reason is structural rather than a matter
-of tuning its constants:
-
-| Policy | Codex writes/h/agent | error p95 (% of window) | missed warnings @90% |
-| --- | --- | --- | --- |
-| every distinct reading | 100.7 | 0.00 | 0% |
-| turn boundary only | 1.8 | 48.76 | 92.1% |
-| movement guard 5% / 60 s (the spike) | 19.2 | 3.43 | 23.1% |
-| movement guard 1% / 60 s | 32.1 | 0.82 | 2.8% |
-| bucket 5% + 300 s heartbeat | 13.1 | 3.80 | 0% |
-| **bucket 1% + 300 s heartbeat** | **34.1** | **0.76** | **0%** |
-
-"Missed warnings" is the share of real compaction events where occupancy truly
-crossed the threshold but the last written reading did not — the "warn me before
-this agent compacts" metric this record exists for, measured over 821 eligible
-Codex events at the 90% threshold.
-
-Three results from that benchmark decide the shape:
-
-1. **A time floor makes cost track producer chattiness, not the agent.** On
-   Claude, the movement guard at 1%, 5%, and 10% with a 60-second floor all land
-   at 59 writes per active hour — 3600/60. The movement clause is nearly inert
-   and the policy degenerates to "one write per minute while active". Because
-   Codex emits roughly 25× more readings per hour than Claude, any time-floored
-   policy needs per-harness tuning. Quantization does not: writes per window fill
-   are capped at `100 / BUCKET_PERCENT` regardless of how often a producer
-   speaks, which is precisely why **one constant is correct for all five
-   harnesses and there is no per-harness knob** (HC-R09).
-2. **Cost does not discriminate.** `DQ-H2`'s recorded failure was 679 writes in
-   221 s — 3.07 writes/s on one agent, 11,061 writes/hour/agent. Every candidate
-   above is 100–1,000× below that, including "write every distinct reading" at
-   1/110 of the failure rate. The recommended policy is 1/324 of it: 34.1
-   writes/h/agent × 600 agents = 5.7 writes/s fleet-wide. Cost is not binding
-   anywhere in the candidate set, so the choice is made on accuracy and
-   structure.
-3. **A coarse bucket couples the write policy to the reader's alarm** (HC-R10).
-   A bucket write fires on *entry* to a bucket, so the reader always shares the
-   truth's bucket — an alarm sitting on a bucket boundary can never be missed,
-   one between boundaries can. Bucket 5% is perfect at 90% and 95% and *worse
-   than the movement guard* in between: 51%, 70%, 74%, and 79% of warnings
-   missed at thresholds of 91, 92, 93, and 94% (n = 672, 590, 436, 289). Bucket
-   1% is the only measured policy with zero missed warnings at every threshold
-   from 80% to 97%, which is what makes the write policy independent of whatever
-   a future consumer decides to alarm on.
-
-Turn-boundary writing is disqualified outright: 48.8% p95 error and 92% of
-warnings missed, because the wedge scenario is a single long turn.
-
-### What would change this
-
-- **If the reader stopped surfacing `ageMs` and `stale`**, quantization's
-  unbounded lag would become silent instead of visible, and the time floor would
-  do real work again; the fallback is the movement guard at 1% / 60 s (32.1
-  writes/h/agent, 1–22% missed). HC-T05 states this dependency.
-- **If per-sync wire cost turns out to be large** — unmeasured, and the open
-  half of `DQ-C1` — the next stop is a 2% bucket at 23.3 writes/h/agent, with
-  the consequence that alarms must then sit on even percentages.
-- **Occupancy above the window caps the guarantee.** `100 / BUCKET_PERCENT` is a
-  write cap only up to the first overflow; above 100% the bucket index keeps
-  climbing.
-
-## Placement and transport (HC-R05)
-
-The record lives at `<agent-dir>/harness-context`, beside `harness-state`. The
-driver records belong together at the agent-directory root; what makes them
-replicate is the transport's include list naming them, not their location.
-
-The measurement that raised the question stands: the fleet's replication
-transport syncs an agent directory through an include list that named only
-`**/resources/**` and `**/status`, so a driver record at the agent-directory
-root matched nothing and would silently never reach a remote reader — no error,
-just a record no remote consumer ever sees. That defeats the reason a catalog
-record was chosen over host-local state
-([decision 0006](../.decisions/0006-observed-harness-state-is-a-driver-written-catalog-record.md):
-"remote supervisors and the TUI read through the catalog they already sync").
-
-The resolution is to name the driver records in that list —
-`**/harness-state,**/harness-context` — rather than to move them under a
-directory whose meaning is the realization surface for Resource bindings. The
-include list is a fleet-side trait specification —
-`context/fleet/traits/fabric/spec.md` in the dotfiles repository — so this is a
-cross-repository change, and it has one property worth stating: it fixes the **already-shipped**
-`harness-state` record, which has the same defect today, without migrating a
-live record.
-
-Two obligations follow on st2's side:
-
-- **Pin the names.** st2 asserts, in a test, the exact record names it expects
-  the transport to carry. The include list lives in another repository, so a
-  rename here would otherwise stop replication silently and nothing in this
-  repository would notice (HC-T08). The test does not prove the other side
-  carries them; it makes st2's half of the contract explicit and breakable.
-- **Stage outside the replicated subtree.** A sibling temporary name inside it
-  is propagated as a real key and restored after a later local delete, so the
-  atomic-write helper stages on the same filesystem but outside the sync root
-  and renames only the canonical path in. Measured free: p50 0.217 ms staged
-  outside versus 0.222 ms as a sibling.
-
-  **Where:** `<catalog>/.st2/harness-context-staging`, derived only from the
-  exact canonical `<catalog>/agents/<host>/<identity>` ancestry. Every ancestry
-  component and the staging directory must be a real directory, and the staging
-  and agent directories must report the same filesystem device; otherwise the
-  writer fails rather than searching upward, following a symlink, or degrading
-  atomic publication to a copy.
-
-  Earlier writers staged at `<catalog>/agents/<host>` and could leave
-  `.harness-context.tmp-<numeric-pid>-<numeric-counter>` behind after a crash.
-  Current-catalog identity walkers overlook only an exact legacy name that is a
-  regular non-symlink file, and leave it untouched for a possibly-live old
-  writer. Directories, symlinks, special files, generic dotfiles, near misses,
-  and prepared-catalog topology remain strict.
-
-  `harness-state` keeps staging beside itself for now. The two records share the
-  extracted `write_json_atomic` helper, which takes the staging directory as an
-  argument precisely because they answer this question differently; moving the
-  shipped record's staging is a separate change with its own risk.
-
-The delivery watcher is unaffected (HC-R08): its allowlist is
-`starts_with(<agent-dir>/resources/inbox)` or the exact path
-`<agent-dir>/status`, and the record is a sibling of neither, so no pump wakes
-and no production change is needed.
-
-No correctness property here depends on the transport. Its adoption record is
-open and forbids exactly that, so replication is what is gained when it arrives,
-never what this subsystem needs to work.
-
-## Producers (HC-R02, HC-R11, HC-R13)
-
-Every live row was measured on 2026-08-29. The Codex payload was captured on
-0.150.1 and its version-coupled arithmetic and notification shape were reverified
-against 0.151.0 before admission. `usedPercent` is that harness's own displayed
-number (HC-R02); where st2 computes it, the row says so.
-

-
-Which adjacent facts each channel actually supplies (HC-R16) — everything not
-listed is `null`, and no producer computes a fact its channel does not carry:
-
-| Harness | `model` | `costUsd` | `rateLimits` | `sessionTotalTokens` |
-| --- | --- | --- | --- | --- |
-| claude | `model.id` | `cost.total_cost_usd` | `rate_limits.{five_hour,seven_day}` | `null` — the payload's `total_*` keys describe the last response, not the session |
-| codex | `null` — the thread carries `modelProvider` only | `null` — Codex reports no cost | `account/rateLimits/updated`, `sevenDay` only — see below | `tokenUsage.total.totalTokens` |
-| pi | `ctx.model.id` | last assistant message's per-message `usage.cost.total` | `null` | `null` in v1 — only obtainable by summing every message's usage, which is a producer-side accumulator, not a free reading |
-| omp | `ctx.model.id` | last assistant message's per-message `usage.cost.total` | `null` | `null` in v1 — same reason as pi |
-| opencode | `session.info.model`, written `providerID/modelID` | `session.info.cost` | `null` | `session.info.tokens` (cumulative, no `total` key — summed by the producer) |
-
-`sessionTotalTokens` is carried only where the channel already computes it. A
-producer that would have to accumulate it itself writes `null` rather than
-maintaining a second running total whose correctness depends on having seen
-every message — tokenlens owns lifetime accounting, and a half-observed sum
-would be a worse answer than none.
-
-### claude (2.1.250)
-
-The status-line payload is the only channel that carries a window. Hook payloads
-carry no token fields at all, and the transcript carries per-message `usage` but
-no window size — so a transcript-only producer would have to invent the
-denominator from a model table, which cannot distinguish a 200k from a 1M tier
-for one model id, and would violate HC-R02.
-
-st2 owns the `statusLine` slot for driver-declared agents: the rendered
-`.claude/settings.local.json` names a tee that records the stdin JSON to the
-harness-context record and then execs the operator's own downstream renderer, so
-a human's status line keeps working:
-
-```text
-.claude/settings.local.json (st2-rendered)
-  statusLine: { type: "command", command: "\"$ST_HOOKS/claude-statusline.sh\"",
-                padding: 0, refreshInterval: 5 }
-
-tee:  stdin JSON --> st2 driver claude-statusline (writes harness-context)
-                 --> run the downstream renderer, resolved in order:
-                       1. $ST_CLAUDE_STATUSLINE_RENDERER
-                       2. ~/.claude/statusline-renderer.json  -> .command
-                 --> if neither resolves, or the renderer fails:
-                       stdout stays empty; the reason goes to stderr
-```
-
-**The subcommand, decided during implementation (2026-08-29):
-`st2 driver claude-statusline`,** a sibling of `claude-observe` rather than an
-event on it. An earlier draft of the diagram above named `claude-observe`, which
-reads well and is wrong in one specific way: that command's contract is "apply
-one Claude HOOK EVENT to observed harness state", and the status line is not a
-hook — `StatusLine` is a settings key and is deliberately absent from Claude's
-registerable event list. Routing it through the hook command would have dragged
-`observe_hook_event`'s event classification and the `SessionStart` claim onto a
-payload that is neither.
-
-**The tee builds no telemetry pipeline (`DQ-C13`, resolved).** A 5-second refresh
-interval makes it ~720 short-lived `st2` invocations per hour per seat — the
-highest-cadence process st2 has, where every other one is long-lived or fires on
-an event — and Claude waits for each to exit. `main` therefore constructs
-`Telemetry::local_only()` for this subcommand: stderr diagnostics, no exporters,
-no global providers, and nothing to flush at exit. Measured against a
-bound-but-never-accepting collector, the alternative is not theoretical: a tee
-that initializes telemetry takes 5.009 s on the path that logs a warning, and
-`claude-observe` takes 10.022 s, against 0.010–0.061 s with no pipeline. An
-unreachable collector would have stalled every render past Claude's own refresh
-interval.
-
-The rule is **cadence, not hook class**, and it lives in
-[`06-observability/spec.md`](../06-observability/spec.md): `claude-observe` is
-event-driven, is named there as `st2-hook`, and stays instrumented. The tee also
-records no `hook_invocations_total` — a metric call that provably cannot reach a
-collector reads as instrumentation and is worse than none.
-
-The tee spawns the renderer and writes the payload to its stdin rather than
-`exec`ing it, because st2 has already consumed that stdin to record the reading.
-The renderer is run as a shell command line, exactly as Claude runs its own
-`statusLine.command`. Every renderer failure is the same failure: one that
-cannot be *started* and one that started and exited non-zero both leave stdout
-untouched. The second could not do otherwise — it may already have written a
-partial line, and appending the raw JSON would corrupt the status line rather
-than restore it — and the first matches it so that a permissions bug on the
-renderer file cannot spew JSON where a missing renderer would not. All three settings
-keys are carried: `padding: 0`, and `refreshInterval: 5`, which is what makes the
-record a live reading rather than one frozen between turns and is well inside the
-300-second write heartbeat.
-
-**Renderer resolution, settled** (`DQ-C2`, closed 2026-08-29 by dotfiles
-PR #2160). Two sources in strict order, first hit wins:
-
-1. `$ST_CLAUDE_STATUSLINE_RENDERER` — an environment variable holding the
-   command. It comes first so a single agent, a debugging session, or a test can
-   override without editing a file.
-2. `~/.claude/statusline-renderer.json` — a file the operator owns, schema
-   `dotfiles.claude-statusline-renderer.v1`, carrying `{"command": …}`. It is a
-   file rather than a settings key because the settings file st2 wins in is the
-   one st2 rewrites, so a renderer declared there would be the very thing the
-   merge does not preserve (HC-R18's inverse). A user-level file st2 never
-   writes has no such hazard.
-3. Neither resolves: write nothing to stdout, and name both paths in a
-   diagnostic on stderr.
-
-The environment variable is checked first and the file second — not merged, and
-never both — so the resolution has one answer and an operator debugging their
-status line has one place to look for it. The file's schema string follows the
-dotfiles namespace rather than st2's, because dotfiles owns the file and its
-shape; st2 reads `command` and nothing else.
-
-The Claude producer implements this. Resolution reads `command` from the file
-and nothing else, so a future key dotfiles adds is inert here rather than a
-second source of truth; an absent `$HOME`, an unreadable file, an unparseable
-one, or an empty `command` each fall through to the next source.
-
-**Chaining is mandatory, not a courtesy** (HC-R18). When no downstream renderer
-resolves — and whenever a resolved renderer fails — the tee writes nothing to
-stdout, so the worst case of st2 occupying the slot is an empty status line. The
-fallback is silence rather than transparency because the payload is machine
-JSON: a slot echoing it repaints
-`{"session_id":…,"transcript_path":…,"model":{…}}` across the operator's
-terminal every five seconds, which is worse for them than a blank row and
-carries nothing actionable. Transparency is the right default for a channel a
-human reads; the status-line slot is not one. The reason goes to stderr instead,
-which the harness routes to its debug log and never to the rendered row, so a
-blank line is still diagnosable — the diagnostic names
-`$ST_CLAUDE_STATUSLINE_RENDERER` and `~/.claude/statusline-renderer.json`
-explicitly, since a seat where neither resolves is exactly the case that
-produces it. Recording is untouched by which arm runs: the reading lands whether
-or not anything is drawn. The same rule governs the hook script's own outermost
-fallback, where no identity, no catalog root, or no `st2` on `PATH` drains stdin
-and prints nothing — it drains rather than exiting, because the harness writes
-the payload into that process and an unread stdin would earn an EPIPE at the
-refresh cadence. Precedence was captured live
-on 2026-08-29 against Claude Code 2.1.250 in four cases through a real pty
-([evidence](./.experiments/2026-08-29-context-signals-and-write-placement.md)):
-`.claude/settings.local.json` > `.claude/settings.json` >
-`~/.claude/settings.json`, and the winning `statusLine` **replaces** the losing
-object outright — a single slot, one command per render, no merge. Since
-`.claude/settings.local.json` is precisely the file the st2 materializer writes for
-driver-declared agents, an st2 entry that does not exec the operator's renderer
-silently and unconditionally removes their status line on every managed agent,
-with no warning. On a host whose global renderer already displays agent id,
-model, context fill, and cost, that is a visible regression st2 would have
-caused without saying so.
-
-The inverse is not fixed by chaining and is worth stating: a `statusLine` a
-human sets in a managed agent's `.claude/settings.local.json` is not preserved
-by st2's materialization of that file, whose merge owns only st2's own hook
-entries. A human renderer therefore belongs in the operator's own settings, with
-st2's tee chaining to it — not in the file st2 rewrites.
-
-Withholding: `current_usage`, `used_percentage`, and `remaining_percentage` are
-`null` until the session's first API response, while `context_window_size` is
-populated from the start. The producer writes the window and withholds
-`usedTokens` and `usedPercent` (HC-R03). `total_input_tokens` must not be
-mistaken for a measurement in that state: the payload builder emits `0` for it
-precisely when `current_usage` is null, so the zero is derived from the absence
-rather than observed. `current_usage` being null is Claude declaring it does not
-yet know.
-
-Adjacent facts on the same payload: `model.id`, `cost.total_cost_usd`, and
-`rate_limits.{five_hour,seven_day}.used_percentage`. The payload describes the
-top-level session; a subagent's own window is not in it, so a runtime whose
-subagent is saturating reports the parent's fill — the grain question is
-`DQ-C9`.
-
-Compaction comes from hooks regardless of the status line: `PreCompact` and
-`PostCompact` carry `trigger ∈ manual | auto`, and `SessionStart` carries
-`source: "compact"` as a third post-compaction edge. `PreCompact` is routed
-through the observe hook **in addition to** the existing pre-compact stub script
-that writes a working-state reconstruction — the two do different jobs and the
-registration carries both.
-
-**The dedupe across three edges, decided during implementation (2026-08-29).**
-One compaction raises all three events, and each arrives in its own short-lived
-hook process with nothing durable passed between them, so a counter that
-incremented on more than one would treble-count every compaction. The dedupe is
-therefore *positional* rather than stateful:
-
-| Edge | Counts | Also does |
-| --- | --- | --- |
-| `PreCompact` | yes — the sole counting edge | writes `trigger` and `lastCompactionMs` |
-| `PostCompact` | no — holds the count it reads | advances `lastCompactionMs` from when compaction started to when the window was emptied |
-| `SessionStart source=compact` | no — deliberately inert | nothing; it is the same compaction seen a third time |
-
-Counting on the **first** edge is what makes the dedupe need no memory. The
-alternative — "count on the second only if the first was seen" — requires
-per-compaction state the record deliberately does not carry (HC-T02), and buys
-nothing: `PreCompact` fires for every compaction, including one whose
-`PostCompact` never arrives because the compaction ended the session or a future
-build dropped the event. The one case where `PostCompact` does count is when it
-finds no counted compaction at all — no record, or one whose `PreCompact` write
-never landed — because it is then the first evidence st2 has, and losing the
-event entirely would be worse than attributing it to the later edge.
-
-A compaction carrying an `agent_id` is a subagent's and never touches the record,
-matching the categorical producer's guard for the same reason: this record
-describes the top-level window (`DQ-C9`).
-
-### codex (codex-cli 0.151.0)
-
-st2 does not re-derive the percentage; it **mirrors** Codex's own
-`TokenUsage::percent_of_context_window_remaining` and subtracts the result from
-100, so the published number is exactly `100 −` the "N% context left" the
-operator reads in the footer:
-
-```text
-window = tokenUsage.modelContextWindow        // absent        -> withhold percent
-                                              // window <= 12000 -> withhold percent
-eff       = window - 12000
-used      = max(0, tokenUsage.last.totalTokens - 12000)
-remaining = max(0, eff - used)
-usedPercent = 100 - clamp(round(remaining / eff * 100), 0, 100)
-```
-
-**Mirroring is not the same function as rounding the used fraction**, and the
-difference is not cosmetic: at an exact half they disagree. Effective window
-200, used 101 — Codex displays "50% left", so st2 publishes 50, while
-`round(used / eff * 100)` publishes 51. Only the mirrored order satisfies the
-producer table's "equals `100 −` Codex's displayed '% context left'". This
-paragraph and the block above **corrected an earlier draft** of this section
-(2026-08-29, with the producer) that spelled the arithmetic as
-`clamp(round(used / eff * 100), 0, 100)`.
-
-One deliberate divergence from the source: where `window <= 12000` Codex returns
-`0` remaining, which mirrored blindly would publish **100% used** for a window it
-cannot normalize. st2 withholds instead (HC-R02, HC-R03) — a saturation the
-harness never displayed is fabricated, not observed. The operands are still
-published: a window at or below the baseline is a window the harness reported.
-
-The 12,000-token `BASELINE_TOKENS` constant is subtracted from **both** the
-numerator and the denominator; it is hardcoded in two Codex crates with no
-configuration override, and it is exactly the kind of version-coupled constant
-HC-T03 names. Recomputed against the measured capture (window 258,400,
-`last.totalTokens` 92,283): 33% used, matching Codex's displayed "67% context
-left"; a naive `last.inputTokens / window` gives ~36% — close enough to look
-right and wrong by construction.
-
-Three traps, all measured:
-
-- `tokenUsage.total` is **cumulative session spend**, not occupancy. It goes to
-  `sessionTotalTokens` and nowhere near a percent.
-- The numerator is `last.totalTokens`, not `last.inputTokens`.
-- The window appears in exactly one place in the whole app-server protocol —
-  this notification. A resumed or re-attached thread is not blind: the
-  app-server replays `thread/tokenUsage/updated` to the newly attached
-  connection before any new turn.
-
-`account/rateLimits/updated` is a separate account-scoped notification and
-supplies `rateLimits`. It carries no occupancy, so it never writes on its own:
-the windows are held and ride the next reading. It is also documented as a
-*sparse rolling update* whose absent fields do not clear a previously observed
-value, which is why the producer merges rather than replaces.
-
-**Only `sevenDay` is carried.** Codex names its windows `primary` and
-`secondary` and identifies them by `windowDurationMins` alone, so the join is by
-duration: 10,080 minutes is seven days, and the one captured Codex rate-limit
-snapshot has exactly that window as `primary`. No 300-minute window and no
-`secondary` was ever observed on this harness, so mapping one onto `fiveHour`
-would be inference dressed as a measurement. `fiveHour` is therefore `null` for
-Codex — **a divergence from this section's earlier wording**, which implied the
-notification filled both windows — until a capture shows the window; admitting
-it is then a one-line change beside that capture.
-
-Codex reports no session cost, so `costUsd` is `null`, and the app-server
-`Thread` object carries `modelProvider` but no model identifier, so `model` is
-`null` too — both examples above are Codex readings and show those nulls
-deliberately.
-
-Compaction: the `contextCompaction` thread item is the live edge (the older
-`thread/compacted` notification is deprecated in the protocol). It carries no
-sizes and no reason, so the trigger is `unknown`. One compaction reaches the
-observer as both an `item/started` and an `item/completed` over the same
-`ContextCompactionThreadItem` id, so the count dedupes on `(turnId, item id)`
-over a short ring; the deprecated notification names only the turn, so its key
-collapses with any item key in the same turn rather than counting beside it. Two
-distinct item ids in one turn are two compactions.
-
-Three limits of the shipped producer, all deliberate:
-
-- **The record is written only where native delivery is configured.** The writer
-  is owned by the app-server delivery pump, beside the harness-state writer, so
-  a Codex seat launched without a delivery config publishes no context record.
-  That matches the harness-state precedent — except that harness-state also has
-  a wrapper-written terminal record and this axis has none, so Codex coverage is
-  exactly "delivery-configured seats".
-- **The compaction counter is incarnation-scoped only when the claim succeeds.**
-  The reset comes from the relaunch claim removing the record (HC-R15), so on the
-  degraded path — a claim that could not be written, which downgrades the *state*
-  writer to token-only and proceeds — no removal happened and the new session's
-  producer continues the predecessor's count. The record still carries the new
-  `incarnation`, so the seam is visible to a reader; nothing else is done about
-  it, because a second removal path would be machinery guarding a case the
-  provenance field already exposes.
-- **A reading replayed on a FRESH binding is dropped; on resume it is not.** The
-  pump skips every frame carrying a `method` while it is still binding. The
-  resume path reads `thread/tokenUsage/updated` out of that skip explicitly,
-  because a resumed thread still holds its context and the claim has just removed
-  the predecessor's record — a seat that resumes and then waits for work would
-  otherwise read `null` against a full window until its next model response. The
-  fresh-binding path needs no equivalent: there is no thread id to match against
-  before the binding candidate names one, and a thread starting now has no
-  history to replay.
-
-Finally, a version note. The arithmetic and notification shape above were
-reverified against codex-cli 0.151.0's Rust source, and
-`CODEX_CONTEXT_VERIFIED_VERSION` pins that literal in the fixture (HC-R13). That
-matches the newest build admitted by `SUPPORTED_CODEX_CLI_VERSIONS`; it does not
-turn the measurement into a semantic-version promise. Every later Codex release
-still requires its own source comparison and live delivery proof before the exact
-launch gate moves.
-
-### pi (0.84.2)
-
-One call answers everything, present on the `ctx` of every lifecycle event:
-`getContextUsage()` returns `{ tokens, contextWindow, percent }`.
-
-The honest-unknown behavior is the load-bearing one: immediately after a
-compaction, and across a process restart until the next assistant usage arrives,
-`tokens` and `percent` are both `null` while `contextWindow` stays populated. pi
-positively says it does not know, and the producer withholds rather than
-substituting (HC-R03) — the same discipline
-[`OHS-R02`](../05-harness-state/requirements.md) applies to the categorical
-axis.
-
-`session_compact` carries `reason ∈ manual | threshold | overflow` and
-`tokensBefore`. The count is harness-durable: `ctx.sessionManager.getEntries()`
-filtered to `type === "compaction"` survives restarts (measured 2 → 3 across a
-compaction and read back correctly on the next process's `session_start`).
-`ctx.model.id` supplies `model`; the per-message `usage.cost.total` supplies
-`costUsd`.
-
-Three facts settled while implementing, each of which changes the shape of the
-producer rather than only its constants:
-
-- **The nulls are already there inside the handler.** `getContextUsage()` called
-  *within* pi's own `session_compact` handler returns `{tokens: null,
-  contextWindow: 4000, percent: null}` — not the pre-compaction numbers — and
-  `getEntries()` has already counted the new entry there (2 → 3 read in the same
-  handler). So the edge and the withheld reading are available together and are
-  emitted as **one frame that lands as one write**. That pairing is load-bearing,
-  not an optimization: a compaction edge always writes while a withheld percent
-  has no bucket, so an edge written on its own would publish the stale
-  pre-compaction numbers beside it, and the null reading proving the window was
-  emptied would not appear until the heartbeat came due.
-- **`message_end` is the emit boundary, not `turn_end`.** The producer emits on
-  `session_start`, `message_end`, `turn_end`, `agent_end`, and `agent_settled`,
-  and holds no cadence policy of its own — the write guard is what bounds cost,
-  at one write per bucket entered however chatty the harness is. The finest
-  boundary is what matters, for the same reason turn-boundary-only *writing* was
-  disqualified above at 92% of warnings missed: the wedge case is a single long
-  turn, and on pi each tool call and its result form their own assistant
-  message. One consequence is worth stating because it looks like a defect and
-  is not: immediately after a compaction, `message_end` for the next assistant
-  message still reads `null` while that message's own `usage` is already
-  populated, and only `turn_end` reports the new occupancy. The producer
-  forwards both honestly — the null is a real reading of "pi does not know yet".
-- **`costUsd` is restated on every frame, from a producer-side hold.** Cost rides
-  only the message-bearing events, but a frame is emitted from events that carry
-  none. The record replaces a reading's fields wholesale — deliberately, so a
-  withheld value is never fabricated from a previous one — so a frame omitting
-  the cost would *erase* the published one at the next turn boundary. The
-  extension holds the last assistant `usage.cost.total` and restates it, which is
-  exactly what pi and omp publish for `costUsd`. HC-R16 now permits this
-  harness-reported per-message scope, and the producer table names it explicitly.
-  Summing to a session total would need the producer-side accumulator HC-R16
-  refuses for `sessionTotalTokens` for the same reason. The hold is
-  cleared on session replacement, so a `/new` session does not restate its
-  predecessor's cost.
-
-### omp (18.0.9, also verified on 18.0.3)
-
-The same call, the same shape — and a different meaning. omp's `tokens` settles
-to the last assistant message's **`input`** alone, where pi's settles to
-`totalTokens`; measured in a controlled lab where the fake provider reported
-prompt tokens of 900, 9,900, and 22,500 and `getContextUsage().tokens` returned
-exactly those figures. So omp under-reports relative to pi by output plus cache
-on an otherwise identical API. This is HC-T03's second version-coupled constant
-and the reason the two harnesses get separate producer rows rather than a shared
-one.
-
-`session_compact` carries **no** `reason` and no `willRetry` (pi's does), so the
-trigger is `unknown` even though omp internally calls its auto-compaction with
-`"idle"` and `"threshold"` — those words are not projected onto the event. The
-count is harness-durable through the same `sessionManager.getEntries()` path as
-pi's.
-
-The producer is otherwise the pi one with two divergences, both measured:
-
-- **omp does not null its reading at the edge.** Inside `session_compact`,
-  `getContextUsage()` still answers (8,100 measured against a 4,000-token
-  window), where pi's returns nulls. Both harnesses therefore send the reading
-  and the edge as one frame; only pi's carries a withheld one.
-- **The emit set drops `agent_settled`**, which omp does not have (0 occurrences
-  in either binary), and the idle edge stays the existing `agent_end` poll. omp
-  fires `session_start`, `message_end`, `turn_end`, and `agent_end` with a
-  working `getContextUsage()` on each.
-
-The version pin (HC-R13, HC-T03) extends the existing launch gate rather than
-adding a mechanism beside it, and the two answer deliberately different
-questions. `SUPPORTED_OMP_MINORS` admits a **minor series**, because a patch
-inside an admitted minor costs no new evidence (decision 0007-omp-is-a-fifth-native-driver-with-its-own-channel-and-a-hard-version-gate); the fixture pins
-the **exact builds** a number's meaning was measured on, because "`tokens` is
-prompt-only input" is a property of a build and not of any documented contract.
-`src/omp_session.rs::the_measured_context_builds_are_admitted_by_this_gate`
-keeps them from drifting apart: a build the fixture claims to have measured but
-the gate would refuse to launch is evidence for a version the fleet can never
-run. pi has no runtime gate at all, so its fixture pins the flake tarball the
-extension check already type-checks and runtime-smokes against
-(`the_measured_pi_release_is_the_one_the_extension_gate_pins`).
-
-Correction of record: the 18.0.3 capture
-([`2026-08-25-omp-harness-integration.md`](../06-omp-driver/.experiments/2026-08-25-omp-harness-integration.md))
-states that the handler `ctx` exposes `{ui}` only. The 2026-08-29 probe run
-against both binaries shows `getContextUsage` present and working on 18.0.3 and
-18.0.9 alike (35 occurrences in each binary) — a probe artifact in the older
-capture, not a version change. `signal` and `agent_settled` genuinely are absent
-from both, as that capture says.
-
-### opencode (1.18.25)

-- **`summary` is overloaded.** On user messages it is an object (`{diffs: []}`)
-  and therefore truthy; the filter for a compaction summary must be
-  `role === "assistant" && summary === true`.
-- **The summarizer's own message poisons the last-assistant reading.** After a
-  compaction the newest assistant message is the summary, whose `tokens.total`
-  is the cost of the summarization call (1,511 measured), not the new context
-  size. The producer skips summary messages when picking the last reading.
-- **`session.updated`'s `info.tokens` is cumulative** and carries no `total`
-  key. It grows without bound and is `sessionTotalTokens`, never occupancy.
-
-`tokens.total` appears only on the final `message.updated` for a message; the
-first carries zeros and no `total`, so the producer requires the KEY and never
-reads a missing one as zero. Which session's reading this is when one server
-holds several — the categorical producer aggregates across them, but two live
-sessions have two windows and one record — is unsettled: `DQ-C10`. v1 is
-last-writer-wins over every session on the stream, which matches the categorical
-producer's aggregate rather than inventing the seat-session rule `DQ-C10` exists
-to defer. `session.compacted` carries `{sessionID}`
-and nothing else — no reason, no timestamp, no sizes — so the trigger is
-`unknown` and the count is st2's own, scoped to this incarnation. The richer v2
-events (`session.next.compaction.started` /
-`ended`, which do carry a reason) exist in the OpenAPI document but did not fire
-once on the legacy path in the measured runs; they are schema-only and no
-producer depends on them.
-
-The producer publishes on one condition only: a `message.updated` that carried a
-fresh `tokens.total`. The adjacent facts arrive a frame later on
-`session.updated` and are folded into producer state, then ride out with the next
-numerator that LANDS a write; publishing on them directly would stamp
-`observedAtMs` on a numerator that may be hours old. They can therefore lag
-several turns — a run of readings inside one bucket writes nothing — and that is
-the intended shape: the record is one coherent snapshot of the turn that last
-landed, stamped with that turn's time, rather than a mix of a stale numerator and
-fresh costs.
-
-For the same reason this producer has no heartbeat: its numerator is pushed and
-not pullable, so it never holds a re-taken reading to publish, and a quiet seat's
-record ages visibly instead (HC-R06). A window that takes no turn does not fill,
-so the aging number stays true. One consequence is expected and must not be
-"fixed": a quiet push-only seat crosses `HARNESS_CONTEXT_STALE` after 60 minutes.
-Codex, pi, omp, and OpenCode obtain fresh occupancy only from harness events.
-Only Claude re-pulls through its five-second status-line cadence. Closing the
-advisory by heartbeating an in-memory numerator would re-stamp `observedAtMs` on
-a reading no one re-took, which is exactly what the writer's contract forbids.
-
-`model` is written in OpenCode's own `providerID/modelID` spelling
-(`opencode/hy3-free`): `modelID` alone is ambiguous across providers, and this is
-the key the window is cached under, so the record always pairs a numerator with
-its own denominator. `usedPercent` is st2's unrounded, unclamped
-`usedTokens / windowTokens × 100`. Rounding it would move the written value into
-a different 1% bucket than the truth and make `HARNESS_CONTEXT_WARN_PERCENT` fire
-below the threshold it names.
-
-Measured on a live 1.18.25 lab run (two turns plus a forced summarize, 571 SSE
-frames): exactly **one** landed write, the compaction counted once with trigger
-`unknown`, and the summarizer's own message — `summary: true`, `tokens.total`
-1,462, and a *different* model id from the turns' — correctly skipped, where
-taking it would have published 0.7% of the window instead of 4.3%.

-## Compaction accounting (HC-R12)
-
-| Harness | Edge | Trigger carried | Trigger words yielded | Count source | Counter scope |
-| --- | --- | --- | --- | --- | --- |
-| claude | `PreCompact` / `PostCompact` hooks; `SessionStart source=compact` | `trigger` | `manual`, `auto` | st2 counts, on `PreCompact` alone — see the dedupe above | incarnation |
-| codex | `contextCompaction` thread item | none | `unknown` | st2 counts | incarnation |
-| pi | `session_compact` | `reason` | `manual`, `threshold`, `overflow` | `sessionManager.getEntries()` type `compaction` | harness-durable |
-| omp | `session_compact` | none | `unknown` | `sessionManager.getEntries()` type `compaction` | harness-durable |
-| opencode | `session.compacted` | none | `unknown` | st2 counts the edge (one per compaction, corroborated 1:1 by the assistant message with `summary === true`) | incarnation |
-
-The vocabulary `manual | auto | threshold | overflow | idle | unknown` is closed
-and additive-tolerant. `idle` is in v1 because omp's internal auto-compaction
-names it; **no v1 producer emits it**, since omp does not project its reason
-onto the event. A word arriving that a reader does not recognize decodes as
-`unknown`.
-
-A harness-durable row degrades to its incarnation-scoped neighbour rather than
-losing the edge: a producer that cannot read the session store sends the edge
-without a count, and st2 increments its own. That is a weaker answer — the scope
-silently narrows, which is why it is stated here — and never a wrong one, and it
-is the only path by which a "harness-durable" row can produce an
-incarnation-scoped number.
-
-"Incarnation" scope means the counter starts at zero when the session record is
-claimed (HC-R15); "harness-durable" means the harness's own session store
-answers the question and the count spans restarts. A consumer comparing counts
-across harnesses is comparing two different questions, which is why the scope is
-stated per row rather than averaged into one number.
-
-Per-compaction detail — sizes, the reason of every earlier compaction, dwell
-between them — is not recorded (HC-T02, `DQ-C6`).
-
-## Session boundary and provenance (HC-R15)
-
-```text
-relaunch: wrapper claims harness-state (existing written claim)
-            \-- and removes harness-context
-first reading of the new session -> new record, incarnation = the claiming token
-straggler write from the old session -> lands; visibly older incarnation, aged by
-                                        observedAtMs; the next real reading overwrites it
-```
-
-The claim path gains one file removal and nothing else. A reader after a
-relaunch sees `null` ("no context yet") rather than the previous incarnation's
-190k, which is the honest answer for a window that has just been emptied. The
-alternative — leaving the old numbers to age out over the 60-minute horizon —
-would show a crash-looping agent the previous incarnation's fill as if it were
-current.
-
-There is deliberately no sequence, no written claim on this record, and no floor
-sidecar (HC-T04).
-
-## Exposure (HC-R14)
-
-`st2 agents --json` (both forms) appends one field per row, always present:
-
-```json
-"context": {
-  "harness": "codex",
-  "usedTokens": 92283,
-  "windowTokens": 258400,
-  "usedPercent": 33,
-  "model": null,
-  "costUsd": null,
-  "sessionTotalTokens": 2235329,
-  "rateLimits": { "fiveHour": 31, "sevenDay": 55 },
-  "compactions": 3,
-  "lastCompactionMs": 1788000097290,
-  "lastCompactionTrigger": "unknown",
-  "observedAtMs": 1788000100000,
-  "ageMs": 4210,
-  "stale": false
-}
-```
-
-`null` when no record exists — the roster's existing convention for
-`observedState`, kept rather than omitting the key, so the wire has one
-convention and not two. The reading projection above is already applied: a
-consumer never re-implements staleness, and never sees a record it would have to
-age itself. `incarnation` and `writtenAtMs` are deliberately not exposed: the
-first is provenance for a reader inspecting the record itself, and the second is
-a write-policy mechanism a roster consumer has no use for once `ageMs` and
-`stale` are computed.
-
-The origin stamp is spelled `observedAtMs` on the roster wire, exactly as in the
-record, following the `sinceMs`/`writtenAtMs` convention the driver records
-already use. An earlier draft of this section spelled it `observedAt`; that was
-an inconsistency within this document rather than a decision, corrected
-2026-08-29 while the field had no producer and no consumer depending on the
-short spelling. `driverDiagnostic`'s own unsuffixed `observedAt` is a different
-record's shipped name and is deliberately left alone — this is one record's
-field agreeing with itself, not a rename campaign across the roster.
-
-Human `st2 agents` output carries the same axis compactly as `ctx:92% ⟳1`,
-beside the existing `obs:` column and prefixed for the same reason — two bare
-words in one row is exactly the ambiguity the ontology's collision rules name.
-`ctx:-` is no record and `ctx:?` is a record whose percent the harness withheld —
-distinct on purpose, since rendering both as `-` would say "nobody is watching"
-for a producer that is watching and honestly does not know, which is Claude's
-state before its first API response. A stale reading is suffixed `stale`. The
-percent is rounded for width and never clamped.
-
-`status`, `desiredState`, `lastActivity`, `observedState`, and
-`driverDiagnostic` keep their exact meanings. `context` is a fourth independent
-axis: none of the five is derived from another.
-
-## Doctor (HC-R17)
-
-Doctor emits an advisory line for an agent it owns in two cases:
-
-| Condition | Advisory | Exit status |
-| --- | --- | --- |
-| `usedPercent` ≥ `HARNESS_CONTEXT_WARN_PERCENT` | context fill, with the reading's age | unchanged |
-| record `stale` while desired state is `running` | the measurement is old, with no reader-health inference | unchanged |
-| no record, unreadable record, or a fresh reading below the threshold | nothing | unchanged |
-
-Neither case is ever a failure. This matches how Doctor already treats the
-categorical axis ([`OHS-R10`](../05-harness-state/requirements.md)): a stale or
-session-dead record beside a `running` desired state is worth a warning and
-never an exit-code failure, and the numeric axis adds no new authority
-(HC-A02).
-
-The stale line does not ask whether the driver still reads the harness. The
-context record has no reader-health evidence, and a live push-only reader can
-expose the same old measurement as a dead reader.
-
-**80 is st2's number, not the harness's.** It is a threshold for "worth a
-human's attention", chosen so an operator sees a filling window with room left
-to act. It is deliberately **not** an estimate of where the harness will
-compact: that point depends on the harness, the model, and the operator's own
-settings — Codex reserves a 12,000-token baseline and a separate auto-compact
-buffer, pi compacts when occupancy passes `contextWindow − reserveTokens` with
-a 16,384-token default, omp exposes an idle-triggered path with its own
-threshold, and Claude's auto-compact window is overridable by environment
-variable. A single st2 constant claiming to predict that would be wrong in both
-directions on most harnesses, and would silently change meaning under a harness
-bump — the failure mode HC-T03 already names for the producer constants.
-
-Because the threshold is st2's own, it carries no coupling to the write policy:
-quantization at 1% is threshold-agnostic (HC-R10), so moving this constant needs
-no change to what producers write, and a reader alarming at some other number is
-equally well served.
-
-## Verification plan
-
-The invariant rows this subsystem must add or amend when implementation lands,
-each only once a real test proves it (per `CLAUDE.md`):
-
-- **Stable roster JSON** (existing row) — wording gains the fourth axis and its
-  null convention. `src/agents.rs::agents_json_has_stable_wire_shape` is edited
-  in the same change and stays the proof; the pinned full-string assertions in
-  `src/agents.rs` change deliberately alongside it.
-- **Scoped delivery-input wakeups** (existing row) — the row's prose enumerates
-  the runtime records that must never wake a delivery pump by name, and gains
-  `harness-context`. The delivery watcher is an allowlist
-  (`starts_with(resources/inbox)` or the exact `status` path), so
-  `src/watch.rs::delivery_watcher_ignores_runtime_records_but_wakes_on_inbox_and_status`
-  stays the proof and stays green with no production change — the row's wording
-  is what moves.
-- **Harness context discipline** (new row, once proved) — stale readings
-  returned with their age rather than derived away; numbers surviving every
-  `observedState: unknown` derivation; withheld values never fabricated; a
-  reading within the written bucket not written; a bucket crossing, a compaction
-  edge, and a record older than the heartbeat each written; the record removed
-  on the relaunch claim.
-- **Doctor advisory, never failure** — a reading at or above the threshold and a
-  stale record beside `running` each produce advisory output and leave the exit
-  status untouched; a fresh reading below the threshold produces nothing. Test
-  in the shape of the existing Doctor coverage in `tests/doctor.rs`.
-- **Replicated-path discipline** (new row, once proved) — st2 pins the exact
-  driver-record names it expects the transport's include list to carry, and no
-  staging file is ever created inside the replicated subtree. Both are silent
-  failures in production, so tests pin `harness-state` and `harness-context`,
-  assert staging below the catalog control directory with same-filesystem
-  atomic publication and cleanup, and bound legacy-reader compatibility to the
-  exact regular-file shape without changing a digest, snapshot, or message
-  address.
-- **Status-line slot chaining** (HC-R18) — a rendered status-line registration
-  invokes the operator's downstream renderer. The slot is single-valued and the
-  winner replaces rather than merges, so a test that only checks st2's command
-  is present would pass while the operator's renderer is silently gone. The
-  proofs therefore run the tee as a process and assert its exact stdout bytes:
-  the renderer's line and only the renderer's line, an empty stdout in every
-  degraded arm — none resolving, a renderer that exits non-zero, a renderer file
-  that is not executable — and a rendered line still produced when recording
-  fails. The degraded arms take their positive evidence from stderr, since an
-  empty stdout alone is also what a tee that crashed instantly would leave.
-  Landed as the invariant row *Status-line slot chaining*
-  (`tests/claude_statusline.rs`).
-- **Per-harness fixture tests** (HC-R13) — one per producer, each decoding a
-  payload captured verbatim from the version named in the producer table and
-  asserting the resulting triple, with the version asserted literally. All five
-  ship, and each pins the numerator its harness actually means: the Claude
-  fixture must fail if the numerator's terms or the percent rule move, the Codex
-  fixture if the 12,000 baseline moves, the omp fixture if `tokens` stops
-  meaning prompt-only input, the pi fixture if it stops meaning the last
-  assistant message's `totalTokens`, and the OpenCode fixture carries the
-  post-compaction summarizer frame so a producer that stops skipping summary
-  messages fails it.
-
-  **Shipped for claude**, over the 2.1.250 status-line payloads:
-  `src/claude_session.rs::a_mid_session_statusline_payload_yields_claudes_own_triple`,
-  `src/claude_session.rs::a_pre_turn_statusline_payload_withholds_rather_than_reporting_zero`.
-
-  **Claude's two fixtures and what each proves.**
-  `tests/fixtures/harness-context/claude-statusline-pre-turn.json` is the
-  verbatim 2.1.250 live capture and proves the withholding — including that
-  `usedTokens` is `null` rather than the `total_input_tokens: 0` sitting beside
-  it. `claude-statusline-mid-session.json` is a **composition**, stated here
-  because it bounds what the fixture proves: the envelope, `context_window_size`,
-  and `rate_limits` are that same verbatim capture, the `current_usage` object is
-  a verbatim `usage` object off an assistant line of a real 2.1.250 transcript,
-  and `used_percentage` / `total_input_tokens` are what the bundle's own builder
-  computes from the two. So each operand is measured and the arithmetic joining
-  them is quoted from the harness, but 2.1.250 was never observed emitting
-  exactly these bytes together — a populated live capture needs a paid turn and
-  none was taken. A bump that moves the numerator's terms or the percent rule
-  still fails the fixture, which is what HC-R13 asks of it.
-
-  **Shipped for codex**:
-  `src/codex_app_server.rs::codex_context_recomputes_the_captured_reading_and_pins_its_verified_version`
-  over `tests/fixtures/codex_token_usage_inbound.jsonl`, asserting
-  `CODEX_CONTEXT_VERIFIED_VERSION` and the baseline literally, and asserting
-  both wrong numerators against the same capture (`total` reads 100, a
-  baseline-free `last.totalTokens / window` reads 36, the truth is 33).
-
-  **Shipped for pi and omp**:
-  `src/pi_channel.rs::the_pi_0_84_2_fixture_pins_total_tokens_as_the_numerator`,
-  `src/pi_channel.rs::the_omp_18_0_9_fixture_pins_prompt_input_as_the_numerator`,
-  `src/pi_channel.rs::a_pi_compaction_withholds_the_reading_it_emptied_in_the_same_write`,
-  `src/pi_channel.rs::an_omp_compaction_yields_unknown_because_the_event_names_no_reason`,
-  `src/pi_channel.rs::an_unreadable_durable_count_degrades_to_counting_edges_not_to_losing_them`,
-  `src/pi_channel.rs::context_frames_decode_conservatively_or_not_at_all`,
-  `src/pi_channel.rs::the_measured_pi_release_is_the_one_the_extension_gate_pins`,
-  `src/omp_session.rs::the_measured_context_builds_are_admitted_by_this_gate`.
-
-  **Shipped for OpenCode**, over verbatim 1.18.25 SSE frames whose own
-  `session.updated.info.version` is the asserted version:
-  `src/opencode_session.rs::captured_opencode_turns_publish_the_assistant_total_over_the_providers_window`
-  (the join, the unrounded percent, and one landed write for a duplicated frame),
-  `src/opencode_session.rs::cumulative_session_tokens_are_the_session_total_and_never_the_occupancy`,
-  `src/opencode_session.rs::neither_summary_shape_is_ever_the_reading`,
-  `src/opencode_session.rs::a_captured_compaction_counts_once_with_an_unknown_trigger_and_no_restamp`,
-  `src/opencode_session.rs::an_unjoined_model_withholds_the_window_and_the_percent_until_the_pull_lands`,
-  `src/opencode_session.rs::a_configured_model_change_makes_the_window_pull_due_without_retagging_the_reading`,
-  `src/opencode_session.rs::the_window_pull_reads_config_providers_through_the_real_client`.
-
-  Each fixture carries *both* numbers from its capture — the one the producer
-  must publish and the one it must not — because the failure this test exists to
-  catch is a change of meaning with no change of shape, which no type gate and no
-  round-trip assertion can see. The pi fixture asserts `23425` and not `23300`;
-  the omp fixture asserts the prompt figure and not that message's `totalTokens`.
-  The row *Version-pinned producer arithmetic* in
-  [invariants.md](../../../docs/st2/invariants.md) names the five.
-
-- **Extension asset runtime smoke** — `checks.pi-extension-types` transpiles both
-  shipped assets and drives every registered handler, because the type gate is
-  provably blind to execution-order defects (a TDZ shipped green through it).
-  Each handler is now driven with three contexts: a bare one carrying none of the
-  telemetry surface (the fail-open path an unmanaged or older build takes), a
-  fully populated one carrying the measured shapes, and one whose every telemetry
-  pull throws. The bare context alone was the gap — it never executes the
-  producer's body at all, so a use-before-declaration inside it would have
-  shipped green through both the type gate and the previous smoke. A compile-time
-  pin on pi's own declarations for `getContextUsage`, `model`, and
-  `sessionManager` keeps the type gate's teeth where the producer's runtime
-  guards deliberately widen the view; what it cannot catch is exactly the change
-  of meaning the fixtures above bound.
-
-  The smoke's channel is a **recorder**, not `true`, and this is the part that
-  makes the check mean something. The extension-to-`pi_channel` frame envelope —
-  `{type: "context", reading: {...}, compaction: {...}}` — has its two halves in
-  different languages in different files, and nothing else couples them: flatten
-  the reading or rename a key and every fixture above stays green while the
-  record is never written for the rest of time. That failure is indistinguishable
-  from the pre-producer state this document describes, which is what makes it
-  silent, and it is the same shape as the replication include list that
-  *Replicated-path discipline* pins names for. So the smoke reads its frames back
-  and asserts the wire: a context frame is emitted at all, the reading carries
-  all five keys, the numerator is each harness's own (23,425 for pi, 22,500 and
-  explicitly not 22,525 for omp), the percent is unclamped, an edge whose session
-  store could not be read still arrives countless, and pi's withheld reading
-  rides the same frame as its edge. Verified non-vacuous by flattening the
-  envelope and watching the check fail.
-
-  Note this check does **not** run under `cargo test` — it is a flake check and
-  must be built explicitly.

-## Open design questions

-Tracked with context in [open-questions.md](./open-questions.md): `DQ-C1` write
-policy benchmark (accuracy half settled, wire-cost half open), `DQ-C5`
-unreadable versus absent, `DQ-C6` history, `DQ-C7` fleet transport cost, `DQ-C8`
-supervisor actionability, `DQ-C9` subagent context, `DQ-C10` OpenCode
-multi-session aggregation.
-
-Resolved, and kept in that file only so their identifiers do not go dangling:
-`DQ-C2` status-line renderer contract, `DQ-C3` status-line settings precedence,
-`DQ-C13` the status-line tee's telemetry cadence,
-`DQ-C4` Doctor exposure and threshold, `DQ-C11` `harness-state`'s placement
-defect, `DQ-C12` a driver record under `resources/` (withdrawn).

-stays opaque. Possession of a URI grants no authority, access, or capability.

-### Resource binding
-
-A publisher-declared edge from one agent to one Resource, written as a
-`resource` node in the agent declaration and carrying an agent-local unique
-name, the URI, a required `reason`, and an optional `inactive-reason`. Bindings
-are desired state: they change only through compare-and-swap publication of the
-whole declaration, and a binding-only change never stops, replaces, or relaunches
-healthy work.
-
-A binding says what an agent *is for* — the work it reads and the durable state
-carriers it owns. It is not a record of what the agent produced.

-## Collision rules

-  which concept is meant.
-- Qualify **supervisor** as [control plane](requirements.md) or

-- Use **supervisor run** for one live control-plane incarnation and
-  **declared supervisor** for the agent reference used in supervisory routing.
-  **Control plane** names the replaceable process concept, not an owning run.
-- Use [presence](../../src/status.rs) for the agent-authored signal and
-  [session state](../../src/reconcile.rs) for runtime liveness. Avoid
-  bare *agent status* when either could be meant.
-- Use [observed harness state](05-harness-state/requirements.md) for the
-  driver-observed activity signal. It is a third axis beside presence and
-  session state: R08's *activity status* stays the declared, agent-authored
-  signal, and neither axis rewrites the other. Bare *activity* does not
-  identify which is meant.
-- *Working state* remains R09's restored durable context and is never a
-  liveness or activity term; the observed signal is **observed harness
-  state**, not *working state*.
-- Use **native driver diagnostic** for typed boundary degradation and
-  **observed harness state** for the harness activity projection. Neither is
-  presence or session state, and a driver diagnostic never rewrites the
-  observed tuple.
-- Use **diagnostic stage**, **reason**, and **source** for the closed fields.
-  Provider error prose may be logged, but must not become consumer branching
-  vocabulary.
-- Use **parked task** or **park decision** for the owning supervisor's policy
-  decision. Do not use *parked* as a session state or replace the runtime
-  observation with it.
-- Use **recovery action** for the structured argv projected with a parked task;
-  it names the exact supervisor scope rather than relying on ambient defaults.
-- Use [agent ID](#agent-id) for immutable logical-subject identity,
-  [agent address](#agent-address) for the mutable host-local semantic route,
-  and [bus address](#bus-address) for its host-qualified form. Do not use
-  *agent identity*, *agent path*, or *bus ID* when the intended axis is not
-  explicit.
-- **Resource** names one concept: a [Resource binding](#resource-binding) and
-  nothing else. The [linked record](#linked-record-retired) plane that once shared the
-  word is retired. Do not reintroduce a second sense.
-- The [agent resource directory](#agent-resource-directory) is not a second
-  sense either — it is where bindings are realized. Say *binding* for the
-  declared edge and *carrier* for the realized bytes when both are in view.
-- Use [working state](#working-state) for R09's restored durable context. The
-  verb is `st2 context` and the directory is `resources/context/`, but the
-  canonical term and its scheme are *working state*, not *context*.
-- Bare **context** is therefore already taken. Say
-  [harness context record](#harness-context-record) for the numeric harness
-  axis, even though its roster key is `context`; say *working state* for R09's
-  restored durable context. The two share no field, no file, and no producer,
-  and neither is [observed harness state](#observed-harness-state) — that is the
-  categorical axis. A record's numbers never imply a state, and a state never
-  implies a fill.
-- Use [context fill](#context-fill) for occupancy as a fraction and qualify it
-  as **harness-native** wherever a reader might otherwise assume one formula.
-  Do not call a cross-harness aggregate of `usedPercent` a measurement; it is an
-  aggregate of operator views.
-- Use [occupancy](#occupancy) for what the window currently holds and
-  **cumulative session total** for lifetime spend. Never *total* unqualified:
-  the harnesses themselves spell both `total`, and dividing the wrong one by the
-  window reports several hundred percent.
-- Use [compaction trigger](#compaction-trigger) for the harness's own stated
-  reason. `unknown` is a value, not a failure, and st2 never infers a trigger a
-  harness did not state.
-- Use [message](../../src/message.rs) for the durable record and
-  [PING](../../src/ding/mod.rs) for its terminal notification.
-- Qualify **event**: a bare *event* in stream context is the durable
-  [event](04-stream/requirements.md) record; the R13–R15 filesystem-watcher
-  usage is a **watcher event**. New requirements text keeps the qualification.
-- Use [key](04-stream/requirements.md) for the event-side grouping axis. The
-  message-side thread/topic axis explored in
-  [issue #49](https://github.com/compoundingtech/st2/issues/49) is a separate
-  concept; do not merge the two by name.
-- Use [stream](04-stream/requirements.md) for the declared producer and
-  **stream task** for its derived companion. A *watcher stream* (R15) is
-  watcher machinery, not a declared stream.
-
-## Avoid
-
-**seat** is not canonical st2 language. Choose by meaning: [agent](https://github.com/compoundingtech/evals/blob/main/AGENT-SPEC.md#canonical-agent-specification)
-for the actor, [agent declaration](https://github.com/compoundingtech/evals/blob/main/AGENT-SPEC.md#complete-declaration-shape)
-for the catalog entry, and [agent runtime](vision.md) for a running
-instance. For admission, use an already-authoritative admission term only if
-one exists; this index does not canonize one.
-
-The rejected word remains visible as design leakage in
-[issue #52](https://github.com/compoundingtech/st2/issues/52),
-[draft PR #55](https://github.com/compoundingtech/st2/pull/55), and one
-[Agent Spec phrase](https://github.com/compoundingtech/evals/blob/main/AGENT-SPEC.md#free-authoring-gate).
-Those references are evidence of recurrence, not authorities for a new st2
-concept.

-# st2 requirements
-
-## Context
-
-st2 implements the executable agent contract in
-[`compoundingtech/evals/AGENT-SPEC.md`](https://github.com/compoundingtech/evals/blob/main/AGENT-SPEC.md).
-The vision is defined in [vision.md](./vision.md). These requirements are the
-current ratified product floor, not the entire future scheduler roadmap; new
-scheduling and workflow constraints belong here only after their behavior is
-accepted.
-
-## Assumptions
-
-- **A01 Declared fleet:** Each runnable agent has one current authored
-  declaration and one pinned host.
-- **A02 Trusted private fleet:** The catalog, runtime state, and participating
-  hosts belong to one trusted operator; st2 is not an adversarial multi-tenant
-  boundary.
-- **A03 Durable host state:** Each host preserves its catalog and runtime state
-  across process restarts. Whole-disk loss and backup are outside st2.
-- **A04 Eventual transport:** Hosts may disconnect; Fabric eventually resumes
-  transport when connectivity returns. st2 does not guarantee network
-  availability.
-
-## Acceptable Tradeoffs
-
-- **T01 Explicit limits:** A documented unsupported case is preferable to a
-  hidden distributed guarantee.
-- **T02 Native ownership over heuristic reach:** A managed harness that cannot
-  declare a matching native session driver and non-secret delivery readiness is
-  rejected rather than routed through generic terminal injection. Ding remains
-  available only for opaque non-harness PTYs.
-
-## Requirements
-
-### Must implement the agent contract
-
-- **R01 Agent-spec compliance:** st2 validates and implements every agent-spec
-  capability it claims to support, and identifies unsupported capabilities.
-- **R02 Canonical KDL and declaration identity:** Hand-authored KDL is the
-  canonical declaration; any generator is optional and its output is
-  inspectable before reconciliation. Declarations are discovered recursively.
-  The target Agent Spec carries an explicit catalog-global `id`; positional
-  `identity` and `host` remain authoritative declaration and legacy-address
-  inputs independent of folder path. Either omitted legacy field retains its
-  path-derived default and mismatch diagnostics. The declaration's parent
-  remains its state/resource anchor. Dot-prefixed and other organizational
-  lifecycle meaning; discovery excludes `.git` and `.st2` control directories
-  at any depth, the catalog-root `pty` runtime directory, and state namespaces
-  directly owned by a declaration.
-- **R03 Host-pinned placement:** Every runnable agent or task resolves to its
-  declared host; host-local roots own reconciliation.
-- **R43 Lifecycle-scoped launch readiness:** Declaration parsing, path
-  resolution and authority, render grammar and destination safety, delivery
-  shape and coherence, identity, and topology validity apply in every desired
-  lifecycle state. Address occupancy applies to running and suspended subjects.
-  Ambient filesystem, render-input, socket, overlay, hook, and delivery
-  readiness apply only to running subjects. Suspended and retired declarations
-  neither require those dependencies to be present nor cause Resource Profile
-  resolution; activation re-establishes every readiness gate before launch.
-
-### Must provide intelligent host supervision
-
-- **R04 Root supervision:** Every machine has exactly one root agent. The
-  deterministic st2 reconciler keeps declared local processes converged; the
-  root observes host-local runtime health, diagnoses failures, performs bounded
-  recovery, and escalates what it cannot resolve.
-- **R44 Declared residency policy:** An Agent Spec declares `residency-policy`
-  as `always` or `on-demand`; omission means `always`. The field controls only
-  whether a desired-running agent is eligible to become cold. It never changes
-  desired state, and suspended or retired agents remain owned by ordinary
-  desired-state reconciliation. `on-demand` requires a declared native session
-  driver. Host policy owns idle thresholds and warm capacity. Inventory exposes
-  declaration policy and runtime residency as separate inputs to the effective
-  decision.
-- **R45 Lossless on-demand transition:** An on-demand transition preserves the
-  exact provider-native session. st2 checkpoints that native binding, stops the
-  complete owned task group, verifies absence, resumes the saved binding,
-  verifies that exact resumed session, and only then delivers demand. Unsupported,
-  mismatched, malformed, or indeterminate evidence refuses the transition; st2
-  never substitutes a fresh session. Runtime residency is one closed axis:
-  `active`, `quiescing`, `stopping`, `cold`, `starting`, or `refused`, distinct
-  from desired state, process observation, harness state, and delivery evidence.
-  Its host-local ledger is durable, generation-fenced, atomically replaced, and
-  restored fail-closed.
-- **R46 Durable wake demand:** The initial authoritative wake sources are a
-  durable inbox message and an explicit operator wake or attach request.
-  Passive CPU, PTY attachment state, filesystem access, and Resource observation
-  do not wake a cold agent. Once checkpointing starts, racing demand remains
-  durable while st2 completes stop, verified absence, exact native resume, and
-  readiness; no cancellation path is required. st2 measures resume-to-ready and
-  demand-to-delivery latency before assigning a latency objective.
-- **R40 Prompt catalog convergence:** A resident catalog supervisor begins a
-  new serialized reconciliation pass promptly after a supported declaration
-  publication becomes durably visible; it does not normally wait for the
-  periodic full-audit interval. Transactional st2 writers and authorized direct
-  atomic declaration replacement remain independent wake sources, so
-  degradation of one source does not disable the other. Accepted events
-  coalesce without concurrent passes. The periodic timer remains the
-  correctness fallback for event loss, unavailable platform watchers, and
-  unsupported direct filesystem mutation, and each degraded wake source emits
-  an operator-visible diagnostic.
-- **R31 Reachable restart bounds:** Within one supervisor run, restart
-  accounting is per task and only successful launches spend the declared
-  budget. `delay` is the minimum launch spacing in either mode. In delay mode,
-  `attempts` limits launches over the sliding `interval` window without parking
-  the task. In fail mode, `attempts` is reachable independent of reconcile
-  cadence: a task that repeatedly launches and dies without being observed
-  alive on every completed accounting pass for a full `interval` is parked for
-  the remainder of its owning supervisor run after its successful-launch
-  budget is exhausted, unless that run grants an explicit per-task unpark
-  request. Granting the request clears exactly that task's park decision and
-  restart accounting; it does not release another parked task or perturb a
-  healthy task, including an identically named task owned by another supervisor
-  scope. A completed pass that does not observe the task alive breaks accrued
-  recovery uptime rather than forgiving failures through silence.
-- **R32 Bounded helper teardown:** After st2 spawns a bounded non-interactive
-  helper, input delivery failure or deadline expiry targets the helper's entire
-  process group, not only its direct child, so teardown includes descendants
-  that outlive that child. st2 either reaps the direct child before returning or
-  transfers wait ownership to a background reaper; the failure remains bounded
-  and reports its originating input error or timeout.
-- **R34 Bounded helper output capture:** Capturing a spawned non-interactive
-  helper's stdout/stderr consumes memory bounded by a fixed per-stream cap
-  independent of the child's output volume and of how many captures run
-  concurrently. When a stream exceeds the cap, the retained bytes are that
-  stream's tail, and truncation is observable. A caller that must consume a
-  stream whole (structured data for parsing) opts in through an explicitly
-  named capture path, so an unbounded read is always visible at its call site.
-- **R39 Disjoint harness-process lifetimes:** Every long-lived st2 process
-  started by an integration/evaluation harness is classified at its spawn
-  boundary as either a durable detached task or a parent-bound owned child
-  group. A durable detached task survives normal return, unwinding, and hard
-  death of the supervisor that launched it; only explicit lifecycle
-  reconciliation may terminate it, and replacement adopts the same runtime
-  identity. A parent-bound group is terminated on normal return, unwinding,
-  and hard parent death. Its cleanup targets the exact owned generation rather
-  than a reusable bare PID, has a finite synchronous deadline, transfers any
-  unfinished waits to a reaper, and includes descendants plus every direct
-  child that requires reaping. Cleanup of one lifetime class never crosses
-  into the other.
-- **R22 Quiet coordination after events:** A network with minimal or default
-  personas stays quiet while useful work continues. Agents coordinate only after
-  an inbox DING, a durable failure, a real blocker, a completion or decision
-  handoff, or a declared schedule with a name. They continue until they resolve
-  the need or hand it off. Repeated status messages and peer polling are not
-  substitutes. Normal supervisors handle failures and blocked work. They do not
-  continuously manage healthy work. A custom supervisor persona can require
-  more frequent coordination. CoS is only an example. st2 does not define or
-  require that role, and it gives the role no standard authority. Transport
-  loss does not stop independent host-local work.
-
-### Must preserve delivery and launch behavior
-
-- **R05 DING/archive semantics:** Inbox delivery, archive precedence, retries,
-  suppression, and restart recovery are deterministic and tested. DING may
-  interrupt agent work, but it must not alter or submit a human's active draft;
-  an unknown interaction state defers delivery.
-- **R06 Restartable launch definitions:** A restarted PTY or exec receives the
-  complete effective launch definition, including environment and supported
-  launch fields.
-- **R42 Launch argv transparency:** Every st2-added launch wrapper preserves the
-  effective task program and each argument as ordered, opaque OS strings. A
-  Linux systemd scope launch disables systemd command-line environment
-  expansion before the wrapper separator, so dollar-bearing literals including
-  `$HOME`, `${UNSET}`, and `$$` reach the task byte-for-byte. Detached and
-  degraded-detached launches remain exact pass-throughs.
-- **R07 Verified hooks:** Required hook content is installed explicitly and
-  verified before a rendered agent depends on it. The selected receipt carries
-  the binary's real source identity regardless of build system. Ordered
-  upgrades are automatic; selecting an older, unorderable, or unreadable exact
-  hook set requires explicit replacement authority. A selection change does not
-  invalidate another running binary's previously installed immutable set. Hook
-  interpreters and runtime dependencies are portable and explicit on every
-  supported package environment.
-- **R33 Provider-visible session restoration:** A shipped session-start hook
-  restores fresh, non-empty durable context and its boot ritual through the
-  provider's supported model-visible output contract. The complete context is
-  preserved without truncation or an argument-size boundary. Missing or stale
-  context is an ordinary cold start, and unavailable enrichment dependencies
-  fail open without blocking provider startup. Any other construction or
-  delivery failure is distinguishable from an ordinary cold start and follows
-  R17's durable error-propagation contract.
-- **R11 Control-plane replacement safety:** Stopping or killing `st2 up` must
-  not stop, restart, or replace any agent it launched. st2 can be reinstalled
-  and restarted while running agents continue unchanged; the replacement
-  control plane adopts those existing processes by immutable agent ID and
-  starts only genuinely missing work. Stopping an agent is a separate, explicit
-  lifecycle action.
-
-### Must externalize agent state and scope
-
-- **R08 Catalog observability:** Catalog-backed state exposes each agent's
-  presence, declared activity status, current plan, and current plan step
-  without PTY or transcript inspection. Presence and activity status are
-  distinct, and stale state is identifiable.
-- **R09 State continuity:** An agent's current work and durable decisions
-  can survive process replacement without depending on its transcript.
-- **R10 Agent-only identity:** st2 models agents. Non-agent identities are
-  unsupported.
-- **R13 Shortest-path reconciliation:** An event is evidence, not permission
-  to run the world. st2 classifies source, path, kind, and affected agent ID or
-  task identity, then takes the shortest correct path from observed state to
-  desired state.
-- **R14 Explicit filesystem-event contracts:** Every watcher is deny-by-default
-  with exact roots, paths, mutation kinds, semantic meaning, debounce policy,
-  and consumer. Reads, opens, unknown paths, and runtime output never trigger
-  generic reconciliation.
-- **R15 Bounded event coalescing:** Accepted event streams use tested
-  head/tail coalescing: immediate head response, one quiet tail, and a hard
-  maximum preventing starvation or unbounded scans, PTY queries, launches,
-  delivery attempts, or writes.
-
-- **R16 Supervisor declaration:** Every non-root agent declares exactly one
-  supervisor by immutable agent ID; root is the only agent without a
-  supervisor. Legacy supervisor references migrate to the resolved parent's
-  migrated ID in the same catalog transition that adds explicit IDs.
-- **R17 Durable error propagation:** Lifecycle, harness/eval, provider-turn,
-  task/exec/PTY, hook, and delivery errors are durably reported to the
-  responsible supervisor with agent ID, task identity, and actionable context.
-- **R19 Targeted reconciliation and typed agent selection:** An exact
-  agent/task selector resolves one catalog-global immutable agent ID and the
-  subject's current pinned host before mutation. Unknown, ambiguous, and
-  wrong-host targets refuse before writes, listing, or actions.
-  Materialization, hook gates, PTY inspection, and plan execution are limited
-  to the selected owner/task; unrelated diagnostics remain visible while
-  unrelated workspaces, tasks, and live PTY PID/generation stay unchanged.
-  Automation, ownership, authorization, and durable graph edges use the agent
-  ID through an explicit ID selector or typed API. Every agent-selecting command
-  keeps address and ID inputs disjoint. When a command defaults from
-  `ST_AGENT`, it consumes that value as a typed exact ID and never reparses it
-  as an address. An ordinary human reference may be a bare agent address or a
-  host-qualified bus address and resolves only when the complete catalog proves
-  one subject. Presentation values never resolve a message, Resource, status,
-  lifecycle, or authoring target.
-- **R20 Portable Resource bindings:** An agent may directly carry zero or more
-  order-independent Resource bindings. Each binding has a non-empty, agent-local
-  unique name and preserves an RFC 3986 absolute URI byte-for-byte without
-  normalization. Its URI scheme is the exact lookup key for an optional,
-  catalog-declared Resource Profile; scheme meaning remains downstream-owned,
-  and st2 ships no built-in profiles. A registered profile may give the URI a
-  contained local denotation under
-  [`07-resource-profile`](07-resource-profile/requirements.md); an unregistered
-  scheme stays opaque. The generic envelope itself does not imply resolution,
-  access, readiness, or lifecycle semantics, and declarations that add such
-  unsupported policy are rejected rather than silently ignored.
-- **R21 Nondisruptive Resource observation:** Machine-readable catalog
-  inspection exposes every Resource binding without interpreting its profile or URI.
-  Resource-only declaration changes do not alter a task's effective launch
-  definition and do not stop, replace, or relaunch healthy work.
-- **R27 Transactional catalog authoring:** One st2 publication operation admits
-  exactly one canonical KDL Agent Spec, with explicit ID, host, and identity,
-  against the complete prospective catalog and structural archive ID index.
-  Publication is compare-and-swap, durable, and atomic: readers observe either
-  the previous declaration set or the next complete set. Reconciliation holds
-  one coherent declaration snapshot
-  through materialization, runtime observation, planning, and execution, so a
-  retirement cannot commit and then be followed by a launch from stale catalog
-  input.
-  A durable incomplete-apply marker fences every declaration-plane snapshot and
-  action after a crashed whole-catalog apply; a resident supervisor stays alive
-  but performs zero lifecycle actions until the transaction is completed.
-  Every successful declaration commit advances a durable monotonic catalog
-  generation; whole-catalog apply advances it before its marker clears. Unlocked
-  diagnostic readers therefore detect even a completed declaration ABA across
-  their observation. A durable incomplete-generation intent fences readers
-  across each single-writer commit and is conservatively recovered by the next
-  exclusive writer. Existing-catalog writer staging exists only in the reserved
-  control plane, never among authoritative declaration leaves; fresh bootstrap
-  stages one non-authoritative sibling because its control plane does not exist
-  yet.
-  Presence, messages, context, and Resource state remain independently writable
-  and are never serialized behind catalog authoring.
-  A publication that replaces an incumbent declaration carrying an ownership
-  marker is admitted only when the caller asserts exactly that marker, which
-  makes publication no weaker an authority boundary than the lifecycle verb
-  authoring the same bytes; an unasserted replacement refuses only for the Nix
-  marker, and a mismatched, unresolvable, or malformed assertion always fails
-  closed. Creating a declaration and republishing byte-identical bytes replace
-  no owned bytes and require no assertion; a candidate that merely claims a
-  marker is not an authority, so the receipt records only a marker the
-  incumbent confirmed.
-  A canonical whole-catalog snapshot externalizes the
-  `st2.catalog-declaration-root.v1` projection while excluding runtime state and
-  workspace content. Its closed projection includes every regular file in a
-  bounded `_templates` library and exact declared canonical workspace directory
-  facts. Whole-catalog apply binds its exact captured desired projection to a
-  caller-supplied input digest before locking or mutation, rechecks the incumbent
-  root digest under the exclusive lock, durably stages the desired bytes, and resumes
-  after interruption solely from a closed marker and its content-addressed
-  stage. A distinct raw-preimage projection may bind a repair or migration to
-  the exact structural declaration bytes of any incumbent without interpreting
-  those bytes. It has a separate hash and receipt type, admits only a fully
-  valid prepared result, and persists its mode in the recovery marker. Raw mode
-  makes no semantic assertion about the incumbent, including its validity or
-  effective PTY root; the caller's exact raw-domain digest is the complete live
-  precondition. Fresh-catalog bootstrap is a distinct create transaction,
-  not a catalog-apply mode: it binds an exact captured prepared projection to a
-  caller-supplied digest, initializes the persistent authoring lock and first
-  catalog generation before visibility, and publishes the complete catalog by
-  one durable no-replace directory rename. A retry is unchanged only when the
-  completed existing catalog has the exact prepared declaration root. Bootstrap
-  validates and preserves one explicit external PTY root but performs no PTY
-  registry I/O; process adoption and PTY-root migration remain outside its
-  atomic boundary because the registry has independent producers. Apply never
-  traverses, hashes, deletes, or relocates workspace or runtime state. An absent
-  canonical identity becomes
-  visible only as a complete bundle; a preexisting declared workspace skeleton
-  remains safe because the durable marker fences declaration readers and
-  marker-time state routing throughout leaf publication and verification.
-  A policy-free prepared-catalog comparison takes the existing shared lock,
-  binds the live side to a caller-supplied declaration-root digest, captures the
-  prepared side through retained no-follow capabilities, and fully admits both
-  projections before returning one versioned receipt. The receipt exposes the
-  before/after declaration roots, exact added/removed/modified projected paths
-  with render/template/static classification, and normalized per-agent
-  Agent Spec-model field-address changes. Addresses expose only the structural
-  and dynamic address keys needed to locate a field; payload values and
-  per-value/agent hashes remain private. Omission and explicit defaults are
-  equivalent. Comparison never
-  writes live declarations, generation/marker state, runtime/state/workspace
-  bytes, or the prepared source, and carries no migration policy or publication
-  authority.
-- **R23 Fail-closed task inventory:** One read-only machine command exposes
-  every desired local PTY and exec task by immutable agent ID, nullable current
-  bus address, task name, runtime id, kind, lifecycle, retirement, desired
-  state, runtime state, PID, creation time, opaque runtime-generation id, and a
-  required resource-observation target. Runtime ID remains task identity. PID,
-  creation time, generation ID, cgroup path, and process-tree root are
-  observation locators only and may change between samples.
-  The resource target is a closed tagged union. A proved live Linux generation
-  exposes its exact unified cgroup-v2 path read from that process's
-  `/proc/<pid>/cgroup`; unit and scope names are not locators. A proved live
-  Darwin generation exposes its PID as a best-effort process-tree root. For
-  PTY, st2 captures the candidate daemon's kernel start token, takes one
-  socket-backed `pty stats --json` snapshot for all candidates, and admits the
-  token only when the named live session reports the same daemon PID and
-  creation generation and a second token read is unchanged. That token fences
-  target observation, as the recorded token does for exec, but its transient
-  availability never changes the PTY generation ID. A changed, recycled, or
-  exited process is never associated with the target.
-  Non-running, indeterminate, degraded, and unsupported observations expose a
-  bounded explicit unavailable reason rather than a nullable or guessed locator.
-  Resource-target unavailability is itself a complete observation and does not
-  turn a trustworthy task inventory into an incomplete one.
-  A proved non-routable retired subject has a null bus address without making
-  coverage incomplete. Unknown, duplicate, malformed, unreadable, timed-out,
-  PID-reused, or otherwise unprovable runtime evidence is indeterminate and
-  makes the versioned envelope incomplete and the command unsuccessful; it is
-  never reported as absence. The command projects a supervisor's known park
-  fault and per-task recovery action alongside the unmodified runtime
-  observation. The action is structured executable argv carrying the exact
-  canonical catalog folder and selected host, so invoking it never falls back
-  to ambient catalog or host defaults. A believable park remains complete,
-  while an unbelievable park marker fails closed like other unprovable
-  evidence.
-  Observation detects semantic declaration drift across its runtime probe,
-  does not invoke a backend for a root positively absent at admission, and
-  performs no reconciliation, cleanup, lifecycle change, state rewrite,
-  resource sampling, or persistent locator registration. An admitted PTY root
-  that changes filesystem identity during the backend probe makes the
-  observation incomplete; the external backend may already have recreated a
-  concurrently removed registry. This diagnostic boundary is not
-  transactionally serialized with catalog or runtime writers and is not
-  control-plane cutover authority. It samples the durable catalog generation
-  and incomplete marker around discovery and runtime observation; any marker,
-  malformed fence, or catalog-generation change makes the envelope incomplete.
-- **R24 Immutable agent ID and mutable agent address:** Each logical agent
-  subject has one explicit, catalog-global, immutable agent ID. IDs are unique
-  across the live catalog and structural archive, across hosts and desired
-  states. The ID survives address, presentation, supervisor, graph-placement,
-  host-placement, desired-state, archival, and runtime-incarnation changes. New
-  subjects use UUIDv7. During migration, every live legacy subject receives its
-  existing host-qualified bus identity as its explicit ID. A structurally
-  archived legacy subject receives those same bytes when they remain unique
-  across the combined live-and-archived subject set; an archived collision
-  receives UUIDv7 and records it in its declaration and tombstone. Migration
-  also durably records each reassigned legacy bus identity together with the
-  subject that kept it and the archived subject's new ID, so readers of legacy
-  records never retype colliding bytes into the wrong subject. This
-  preserves current runtime and archived continuity without admitting duplicate
-  IDs. Supervisor resolution uses the combined pre-migration live-and-archived
-  subject index. The same transition rewrites every reference to the parent's
-  migrated ID. A missing or ambiguous reference refuses before writes with
-  `legacy-supervisor-unresolved`; the operator must unarchive and repair that
-  declaration through the pre-activation legacy authoring path, then retry.
-  A frozen legacy ID becomes opaque and keeps its original host-looking bytes
-  after a later host move. Retirement makes the subject non-routable but
-  preserves its ID. Reintroducing the same ID denotes the same subject; a
-  replacement subject receives a newly generated ID. Suspended subjects retain
-  their route and occupy the address namespace. Retired subjects release their
-  address.
-  An Agent Spec may declare an optional mutable `address`. Its effective
-  address is the explicit value when present and otherwise the positional
-  legacy `identity` value. An explicit address is at most 255 ASCII characters
-  and is a dotted sequence of 1-to-63-character segments. Each segment contains
-  only lowercase letters, digits, and hyphens and begins and ends with a letter
-  or digit. Effective addresses are unique per logical host among running and
-  suspended subjects. Host qualification produces the human-routable bus
-  address `<host>.<address>`. Assigning the first explicit address atomically
-  cuts ordinary routing over to it. The prior effective address stops resolving
-  immediately and is reusable; st2 retains no implicit alias, redirect,
-  history, or timed compatibility route. Exact ID lookup uses only explicit ID
-  syntax or a typed API.
-  Address-only changes preserve the logical subject, declaration-state anchor,
-  ID-keyed supervisor edges, inbox, archive, context, Resource state, task IDs,
-  live PTY PID/creation identity/generation, and provider session. A host, graph,
-  or launch change retains the subject ID but follows its own runtime lifecycle
-  rule.
-- **R25 Bounded presentation and constrained identity authoring:** Agent Specs
-  may declare optional, non-empty `name` and `description` strings in canonical
-  KDL and the readable TOML/JSON forms. `name` is a non-unique mutable human
-  label, limited to 160 Unicode scalars; `description` is an enduring
-  responsibility boundary, limited to 1,000. Both are single-line: Cc control
-  characters and U+2028/U+2029 are invalid. Omission means absence.
-  Presentation is never an address or ID, and the declaration is its sole
-  source of truth; a sibling `name` file is ignored without migration or
-  compatibility behavior.
-  `st2 agent address`, `st2 rename`, and `st2 describe` set or clear only their
-  corresponding direct field in one canonical KDL declaration selected by
-  explicit immutable ID. The address command validates host-local effective
-  address uniqueness against the complete prospective catalog. All three
-  preserve unrelated source bytes, serialize cooperating local writers through
-  the persistent shared `.st2/catalog-authoring.lock`, reject a stale source
-  before atomic replacement, fsync the result, and return classified receipts.
-  The lock inode is never removed or stale-recovered and defines one local
-  POSIX filesystem/kernel exclusion domain; it is not cross-host coordination
-  or OS isolation from direct external writers. TOML, JSON, declarations
-  explicitly marked Nix-owned, agent-ID changes, and malformed or ambiguous
-  targets fail closed. Nix emitters must publish that marker before authoring
-  is activated. In the trusted-fleet model, caller-supplied `ST_AGENT`
-  provides a guardrail, not authentication: a catalog agent may edit itself or
-  a descendant reached through ID-keyed supervisor edges, while its absence
-  selects the operator path.
-- **R26 Nondisruptive identity and presentation projection:** Runtime
-  ownership, default task IDs, provider bindings, and `ST_AGENT` derive from
-  immutable agent ID rather than mutable address or presentation. Compact agent
-  lowering assigns its canonical task the explicit ID `<agent-id>`. Any
-  long-form named task without an explicit task ID defaults to
-  `<agent-id>.<task-name>`, including a task named `agent`; an explicitly
-  authored task ID remains authoritative. State and Resource paths remain
-  anchored at the declaration parent under R02. For every healthy managed PTY,
-  st2 reconciles a versioned owned metadata snapshot containing immutable actor
-  ID, current bus address, and optional description through one exact task-ID
-  metadata patch. Only the canonical compact agent task whose task ID equals
-  the agent ID maps optional name to native PTY display metadata; other PTYs
-  preserve their task-specific display convention. Projection
-  preserves unrelated tags, removes absent owned values, reports and retries
-  failure, and is idempotent. Address and presentation projection never uses
-  human-address resolution or enters launch, teardown, garbage collection,
-  replacement, or flapping accounting. The current lowered Agent Spec remains
-  the only source of address, name, and description; an explicit ID roster
-  query returns the subject's current address and presentation without
-  publishing a duplicate Agent Spec state file.
-- **R41 Typed agent desired state:** Every admitted Agent Spec has exactly one
-  whole-agent desired state: `running`, `suspended`, or `retired`. Omission and
-  legacy `retired #false` mean running; legacy `retired #true` means retired
-  without a rationale. New suspended and retired declarations require one
-  valid human rationale of 1..160 UTF-8 bytes. Running forbids a rationale, and
-  a declaration that mixes legacy `retired` with `desired-state` is invalid.
-  Running uses ordinary task reconciliation. Suspended and retired agents do
-  not launch or materialize tasks and tear down every live owned task,
-  including generated companions. Suspension preserves the declaration,
-  inbox, context, resources, and existing `keep` and `adopt-only` policy; resume
-  grants no replacement authority beyond ordinary reconciliation. Retirement
-  retains its stronger collection contract.
-- **R28 Desired-state authoring and observation:** `st2 agent desired-state`
-  changes lifecycle intent only in one canonical KDL declaration selected by
-  explicit immutable agent ID. It uses the same source-preserving, durable,
-  exact-target, trusted-fleet authority boundary as presentation authoring and
-  refuses malformed, ambiguous, or unsupported declarations. A Nix-owned
-  declaration refuses authoring unless the caller asserts exactly the ownership
-  marker that declaration carries; a mismatched, absent, unresolvable, or
-  malformed assertion fails closed. Every desired-state mutation builds one
-  complete prospective catalog under the authoring lock and compares incumbent
-  and prospective core `ERROR` identities as `(code, catalog-relative path,
-  agent)` multisets. It refuses every positive delta, without using messages
-  that contain shadow paths, so lifecycle authoring cannot introduce a core
-  error but an unrelated pre-existing error does not block repair or teardown.
-  This lifecycle-delta admission applies equally to ordinary and marker-matched
-  authoring; the marker remains authority only. It is the only authoring verb
-  with asserted generator authority, because a projection has one transition
-  its own source cannot express: the source change being projected is the
-  seat's removal. Entering running activates launch readiness and address
-  admission; entering suspended reacquires address and topology admission while
-  readiness remains inactive; entering retired exposes retirement topology
-  admission. Running is canonically omitted;
-  suspended and retired states persist their rationale. Its receipt proves the
-  declaration edit, never runtime convergence. Human listing, roster JSON, task
-  inventory, and Doctor expose desired state without conflating it with
-  presence or observed liveness.
-- **R29 Visible, nondisruptive launch drift:** st2 derives a versioned desired
-  launch fingerprint from the minimal effective fields it already passes to a
-  task. Only an st2 launch records an observed fingerprint, bound to that
-  launch's exact runtime identity and creation incarnation. A missing or
-  mismatched binding reports `unknown`; otherwise inspection reports
-  `converged` or `drifted`. Healthy `drifted` and `unknown` tasks are adopted
-  without implicit restart.
-- **R30 Explicit replacement boundary:** An absent or dead active task launches
-  from the latest current declaration. Retirement stops live work and prevents
-  relaunch. Replacing live work is a separate, explicitly selected operation
-  fenced by catalog, host, effective PTY root, task set, and an exact runtime
-  identity recheck immediately before disruption. Replacing an immutable agent
-  ID remains retire-old/add-new; changing an agent address follows R24's
-  nondisruptive cutover. Every behavior remains complete with an ordinary
-  catalog folder and without CAS, captured generations, or replacement
-  journals.
-- **R35 Authoritative admitted graph:** `st2 catalog graph --json` is the sole
-  catalog topology authority. For each uniquely admitted agent it publishes
-  the effective native session driver plus direct parent, root, depth, and
-  nearest-parent-first ancestor facts. Duplicate agent ID, missing parent,
-  supervisor cycle, bounded-depth overflow, and a per-host root count other
-  than exactly one are errors; affected topology facts are null and the graph
-  is incomplete. Consumers do not reimplement those generic graph rules.
-- **R47 Published actor resource roots:** The admitted graph publishes one
-  catalog-relative resource root for every actor in the live catalog: each
-  declared agent's declaration directory, and each direct OMP actor directory
-  `agents/<host>/direct.omp.<encoded-pty-id>` that holds no declaration,
-  together with the exact PTY session ID its identity decodes to. Publication
-  is additive: the graph schema and completeness are unchanged. Consumers
-  bound per-actor views at these roots rather than inferring subject
-  boundaries from names, depth, or file shapes.
-- **R36 Explicit native delivery readiness:** Managed Claude, Codex, pi,
-  OpenCode, OMP sessions declare their matching native session driver and one
-  tagged delivery-readiness value. Credential readiness may name a non-secret
-  account identifier or leave selection to the driver. Anonymous OMP readiness
-  names OMP and a non-empty normalized model set. Readiness is declaration
-  state, never inferred from activity, argv, process names, or credentials.
-- **R37 Retirement settles the inbox:** Every reconciliation of a retired
-  local agent first tears down every live owned task. Only after every teardown
-  attempt for that agent succeeds does the pass archive its canonical inbox
-  messages; any teardown failure leaves the entire inbox in place and retries
-  teardown plus settlement on the next reconciliation. The archive filename is
-  the durable receipt: repeated settlement and a sync-restored duplicate remove
-  the inbox copy without overwriting the archived bytes. Suspension retains the
-  inbox and does not settle it.
-- **R48 Direct actor archival:** A local direct OMP actor directory whose PTY
-  session has no running record in the catalog's PTY registry, continuously
-  for the catalog's `archive-after` grace period measured from the
-  supervisor's first observation of that death, leaves the live catalog
-  through the same structural archive and per-pass bound as a retired seat: a
-  whole-directory move plus a tombstone, reversible by `st2 catalog
-  unarchive`, nothing deleted. A PTY that runs again, and an unarchived actor,
-  each serve a fresh grace period. Liveness comes only from the strict
-  reversible PTY-ID decoding and the exact registry record; names, mtimes, and
-  activity never decide it. Archive retention is outside this requirement
-  ([DQ6](spec.md#open-design-questions)).
-- **R38 Codex schema admission:** Codex app-server launch is gated by an
-  admitted fingerprint of the delivery-critical schema projection. Admission
-  proves each emitted or consumed method discriminator is linked to its exact
-  payload arm and recursively covers the referenced definitions. Behavioral
-  turn, resume, and receipt evidence is reviewed separately; a schema match
-  alone does not claim it.
-
-### Must support rolling fleet upgrades
-
-- **R49 Adjacent-release fleet window:** A Fractal fleet must support adjacent
-  published releases N and N-1 together for at least 14 days without lost work,
-  duplicate schedule fires, or blocked schedules. Features requiring support
-  from every member activate only when all active members advertise support.
-  An older-release member returning after being offline for up to 30 days must
-  neither block nor corrupt the fleet. Downgrade is not required.
-  Implementation remains open in [#4002](https://github.com/compoundingtech/fractal/issues/4002);
-  the protocol design and acceptance evidence are in
-  [the compatibility contract](../st3/compatibility.md).

-# st2 specification
-
-This document specifies st2's current implementation contract. It builds on
-[requirements.md](./requirements.md).
-
-## Status
-
-Active. This is a concise map to the implementation and its evidence, not a
-replacement for the README, CLI help, KDL examples, or tests.
-
-## Scope
-
-st2 validates a declared agent fleet, materializes agent workspaces, launches
-host-local work, adopts and supervises independently surviving tasks, and
-delivers messages. The agent grammar and harness-facing contract remain
-canonical in
-[`compoundingtech/evals/AGENT-SPEC.md`](https://github.com/compoundingtech/evals/blob/main/AGENT-SPEC.md).
-
-## Rolling fleet compatibility (R49)
-
-```text
-authenticated member capabilities
-  -> all-active-member support -> fleet feature activation
-return after >30 days offline -> re-sync fence -> write admission
-```
-
-The Fractal fleet protocol design, current implementation gaps, checkpoint and
-client boundaries, and required test matrix live in
-[the compatibility contract](../st3/compatibility.md). This extends the fleet
-requirements beyond the legacy st2 catalog implementation described below.
-Implementation of R49 is open in [#4002](https://github.com/compoundingtech/fractal/issues/4002).
-This specification does not claim the window is already implemented.
-
-## Decision citations
-
-Decision records are cited by their full filename stem, `NNNN-<slug>`. Bare
-numbers are ambiguous for 0005, 0007, 0014, and 0015; their collisions are
-recorded history, and numbers are never reused under
-[`0006-observed-harness-state-is-a-driver-written-catalog-record`](.decisions/0006-observed-harness-state-is-a-driver-written-catalog-record.md).
-
-## Canonical Agent Spec eval teams
-
-An eval may opt into `canonical-agents` after its fixture copy and deterministic
-run steps have populated the hermetic temporary catalog. The directive is
-mutually exclusive with compact `team` / `agent` declarations. st2 recursively
-discovers the catalog, preserves explicit `identity` and `host` authority
-independent of organizational placement, and projects only declarations
-resolved to the eval host. Each declaration parent remains its native
-state/resource anchor. The resulting local Agent Spec vector flows unchanged
-through launch admission, kickoff resolution, supervision, logging, and
-declaration-driven teardown; remote-host declarations remain inert.
-
-Admission applies `validate_for_host` strictly, then fails before spawn when
-discovery is malformed or warning-bearing, when the selected local projection
-is empty, duplicate, non-running, root-overriding, or unrunnable, or when any
-resolved local task runtime ID is empty or duplicates another local task.
-Materialization warnings and backend launch errors are fatal. The kickoff
-target must resolve to exactly one local agent. The eval owns one native
-`CATALOG` / `ST_ROOT` and its `<catalog>/pty` registry; declarations cannot
-override those roots. Local workspace renders are materialized before any
-agent task starts.
-
-Native inbox/archive paths are derived once from the admitted Agent Spec paths
-and carried as frozen data; routing never re-discovers the mutable catalog.
-The requester alone is an explicit eval-owned flat mailbox. Multi-agent
-completion retains the worker-report-before-supervisor-confirmation ordering.
-For a singleton, the eval snapshots the requester inbox before kickoff and
-completes only for a newly appearing interviewer reply whose timestamp is
-at-or-after the exact kickoff receipt. The filename snapshot rejects
-future-dated pre-seeded messages while `>=` accepts a causally new same-ms
-reply. Canonical completion is a gating judge, so a timeout cannot pass on
-unrelated final-state checks alone.
-
-Without `canonical-agents`, fixture declarations are not discovered or launched
-and compact evals retain their catalog-less flat bus. This explicit opt-in keeps
-ordinary fixtures inert while allowing the same canonical declaration to be
-exercised in an eval and real work. Parser and admission evidence lives in
-`eval_spec::tests::canonical_agents_is_bare_once_and_excludes_compact_agents` and
-the `canonical_*` unit tests. Named-PTY end-to-end cases prove strict
-pre-spawn refusals, poisoned ambient-root isolation, real render
-materialization, frozen routing after declaration removal, singleton
-completion, custom task-ID supervision/logging/teardown, and the no-opt-in
-legacy control in `tests/eval_run_e2e.rs`.
-
-## Immutable agent ID, mutable address, and presentation (R02, R08, R11, R13, R19, R24-R26)
-
-This section is the accepted target contract. Its mutable-address half is
-implemented: the grammar, host-local address uniqueness, `st2 agent address`,
-and the fail-closed bare-or-qualified reference resolution. Its immutable-ID half
-is not: no writer emits `id`, so the positional `<host>.<identity>` bus identity
-remains the durable key every ownership, task-identity, and record surface uses.
-[`0015-immutable-agent-id-and-mutable-address` Amendment 1](.decisions/0015-immutable-agent-id-and-mutable-address.md)
-stages that half behind named triggers and
-[DELTA-003](.delta/DELTA-003-agent-address-not-implemented.md) records what it
-still requires.
-
-An Agent Spec separates four values that the current implementation overloads:
-
-| Concept | Declaration/runtime form | Mutability | Scope | Use |
-|---|---|---|---|---|
-| agent ID | required target field `id "<agent-id>"` | immutable | catalog-global | logical subject, ownership, automation, durable graph edges |
-| agent address | optional `address "<address>"`; positional `identity` is the legacy fallback | mutable | unique per logical host | human routing |
-| bus address | `<host>.<effective-address>` | derived | catalog | qualified human routing |
-| agent name | optional `name "<name>"` | mutable | non-unique | presentation only |
-
-Before ID-aware routing activates, catalog migration adds an explicit `id` to
-every live and structurally archived declaration. It first assigns each live
-legacy subject its existing host-qualified bus identity, preserving current
-runtime IDs and declaration-anchored state. An archived subject receives those
-same bytes when unused across the combined live-and-archived set; a collision
-receives UUIDv7, recorded in both its declaration and tombstone. Migration also
-durably records each reassigned legacy bus identity with the subject that kept
-it and the archived subject's new ID, so readers of legacy records never retype
-colliding bytes into the wrong subject. Supervisor
-resolution uses the combined pre-migration live-and-archived subject index. In
-the same atomic catalog transition, every reference is rewritten to its
-parent's migrated ID. A missing or ambiguous reference refuses before writes
-with `legacy-supervisor-unresolved`; before activation, the operator must
-unarchive and repair that declaration through the ordinary legacy authoring
-path, then retry migration.
-Unarchive preserves the migrated ID, validates its uniqueness against the
-prospective live-and-archived set, and refuses an unmigrated archive after
-activation. New subjects receive UUIDv7 IDs. A legacy frozen ID's original
-host-looking prefix becomes opaque: a later host move changes current placement
-and bus address, not the ID.
-
-A subject's ID survives address, name, description, supervisor, graph
-placement, host placement, desired state, archival, and runtime-incarnation
-changes. Retirement makes the subject non-routable and releases its address but
-preserves the ID. Reintroducing the same ID denotes the same subject; a
-replacement subject receives a newly generated ID.
-
-`address` is an optional semantic alias. When omitted, positional `identity` is
-the effective legacy address. When present, it is the effective address and the
-legacy fallback no longer resolves as an ordinary reference. An explicit
-address is at most 255 ASCII characters and is a dotted sequence of
-1-to-63-character segments. Each segment contains only lowercase letters,
-digits, and hyphens and begins and ends with a letter or digit.
-
-Host qualification forms the bus address:
-
-```kdl
-agent "0199b8f4-8d3a-7c21-9a44-6f85b7320ea1" {
-  id "0199b8f4-8d3a-7c21-9a44-6f85b7320ea1"
-  host "dev3"
-  address "dotfiles.fractal.keymap.verifier"
-  name "Keymap verifier"
-  description "Verifies Fractal keyboard behavior and regression evidence."
-}
-```
-
-```text
-agent ID       0199b8f4-8d3a-7c21-9a44-6f85b7320ea1
-agent address  dotfiles.fractal.keymap.verifier
-bus address    dev3.dotfiles.fractal.keymap.verifier
-agent name     Keymap verifier
-```
-
-Every admitted effective address is unique within its resolved logical host
-among running and suspended subjects. Retired subjects do not resolve and do
-not occupy the address namespace. The complete prospective catalog enforces
-both explicit-address collisions and collisions involving an addressless
-declaration's identity fallback. The same address may exist on two hosts.
-Address and ID are separate typed namespaces; equal string bytes do not collide.
-
-An explicit ID selector performs only catalog-global ID lookup. An ordinary
-reference uses this fail-closed candidate set:
-
-1. when the caller pins a host, treat the complete input as an address in that
-   host and also try the qualified split whose prefix equals the pinned host;
-2. otherwise, treat the complete input as a bare address across the selected
-   catalog and also try every dotted split whose prefix is an admitted logical
-   host and whose suffix is an effective address in that host;
-3. deduplicate candidates by agent ID and succeed only when exactly one subject
-   remains.
-
-This rule makes a dotted semantic address and a host-qualified bus address
-decidable without guessing which dot is a separator. Absence and multiple
-distinct subjects fail with address-specific diagnostics.
-
-Ordinary CLI references and message recipients use that address algorithm.
-Every agent-selecting command exposes mutually exclusive address and exact-ID
-forms. A command that defaults from `ST_AGENT` consumes it through the typed ID
-path; generated hooks and channels use the exact-ID form rather than passing it
-to an address parser. Exact subject selection never falls through to address
-lookup. Internal ownership, supervisor edges, replies, message provenance,
-authoring authority, and lifecycle plans carry agent IDs, not reparsed
-free-form references.
-
-Assigning or changing `address` is one atomic address-book cutover. The old
-address stops resolving as soon as the new catalog generation is visible and
-may be claimed by another subject. st2 stores no rename history, redirect,
-implicit alias, or time-bounded compatibility route. A stale caller fails
-loudly and refreshes the roster. Catalog-generation and incomplete-transaction
-fences keep each lookup on one coherent before-or-after address book.
-
-Address changes do not alter the subject's declaration-parent state anchor,
-ID-keyed supervisor edges, task IDs, launch fingerprints, workspace, inbox,
-archive, context, Resource state, provider-session binding, or runtime
-ownership. A healthy task keeps its PID, creation identity, and generation.
-Host, graph, task, and launch changes retain the logical subject ID but still
-follow their own field-specific runtime rules; logical-subject continuity does
-not imply process-incarnation continuity.
-
-`name` remains a non-unique human label and `description` remains the enduring
-responsibility boundary. Omission is the only cleared representation. Name is
-limited to 160 Unicode scalars and description to 1,000. Explicit empty,
-surrounding-whitespace, Cc-control, U+2028/U+2029, or over-limit values are
-invalid; slash and backslash remain ordinary printable characters. Neither
-field participates in identity, address resolution, authorization, durable
-paths, or lifecycle. The Agent Spec declaration is their sole source of truth.
-`<agent-dir>/name` is hard-retired: st2 neither reads, writes, migrates, nor
-interprets it.
-
-`st2 agent address`, `st2 rename`, and `st2 describe` accept an explicit agent
-ID and either a value or `--clear`. Address clearing restores the positional
-identity fallback and is admitted only when that effective address remains
-unique. They
-edit canonical KDL only. Each operation:
-
-1. acquires the persistent exclusive
-   `<catalog>/.st2/catalog-authoring.lock` before discovery;
-2. resolves exactly one declaration by immutable ID and applies the
-   caller-supplied `ST_AGENT` self/descendant guardrail when present;
-3. refuses declarations explicitly marked `meta { managed-by "nix" }`,
-   unsupported formats, malformed catalogs, ambiguous targets, and direct ID
-   mutation;
-4. applies one span-bounded edit, reparses and validates the complete candidate
-   catalog, including effective-address uniqueness and ID uniqueness against the
-   structural archive;
-5. fsyncs a temporary under the reserved `.st2` control plane, rechecks the
-   original inode/version and bytes, atomically renames it through retained
-   no-follow directory capabilities, then fsyncs the declaration directory.
-
-`ST_AGENT` carries the catalog-global agent ID and remains an exact actor
-selector supplied by reconciliation, not the mutable bus address. Host
-placement comes from the declaration/runtime context rather than being encoded
-into `ST_AGENT`. `ST_AGENT` is a trusted-fleet convention rather than an
-authenticated capability: a same-UID caller can alter or remove it, and its
-absence selects the operator path. Nix generators must emit the ownership
-marker before activating a binary with authoring commands; st2 cannot infer an
-unmarked generator from KDL bytes.
-
-The lock file is a persistent real inode and is never removed or
-stale-recovered. It serializes cooperating st2 declaration readers and writers
-in one local POSIX filesystem/kernel lock domain. Direct same-UID writes and
-independently synchronized hosts do not participate; the source recheck detects
-observed interference but is not a distributed lock service.
-
-Roster and graph JSON append `id`, `address`, and nullable `busAddress` while
-preserving the existing field order and meanings required by their compatibility
-invariants. A retired non-routable subject has null `busAddress` without making
-the envelope incomplete. The existing `identity` field remains the positional
-declaration key and legacy address fallback; consumers do not treat it as the
-agent ID. `name` and `description` remain separate presentation fields. An
-exact ID roster query returns one subject plus its current host and nullable
-effective address. An ordinary address query fails on absence or ambiguity.
-
-For each healthy managed PTY, reconciliation uses one atomic exact-task-ID
-`pty metadata patch --id <task-id>` request. Compact agent lowering assigns its
-canonical task the explicit runtime ID `<agent-id>`. Every long-form named task
-without an explicit task ID defaults to `<agent-id>.<task-name>`, including a
-task named `agent`; explicitly authored task IDs remain authoritative. This
-preserves every legacy task ID and socket path because each frozen ID equals its
-former bus identity and the lowering rule itself does not change. Host placement
-is not separately concatenated into a default ID; host-looking bytes inside a
-legacy ID are opaque. Every PTY receives the exact owned tag snapshot
-`agent.presentation.schema=2`, `agent.actor.id=<agent-id>`,
-`agent.actor.address=<bus-address>`, and optional
-`agent.presentation.description=<description>`. Clearing a value removes only
-its owned tag. Unrelated tags remain unchanged. Only the canonical compact agent
-task whose task ID equals the agent ID carries the compatibility tag
-`role=agent` and maps `name` to native `displayName`; other PTYs clear that role
-tag and retain their task-specific display convention. Name is not duplicated
-in tags. Exec tasks receive no PTY metadata.
-
-One effective metadata delta emits one coherent `metadata_change` event, while
-an unchanged patch emits none. Projection failure reports and retries but never
-enters launch, teardown, garbage collection, replacement, or flapping
-accounting.
-
-## Service-principal request transport
-
-A non-agent service that needs bounded judgment work may declare only its bus
-endpoint at
-`principals/<host>/<identity>/principal.kdl`:
-
-```kdl
-principal "example-ci" host="host-a"
-```
-
-The declaration creates no task, presence, persona, or Agent Spec authority.
-Its content must exactly match its canonical path. `st2 request send` accepts
-only such a principal as the caller and only a discovered Agent Spec as the
-recipient, so a service neither impersonates an agent nor depends on the flat
-orphan-recovery layout.
-
-The caller supplies an idempotency key, a JSON body, and typed string tags.
-Before the native message is published, st2 atomically reserves one random
-canonical message filename and the exact request envelope under the
-principal's `resources/request-state/`. Replays finish that same publication;
-reuse of the key with different caller, recipient, body, or tags fails. An
-agent's `st2 request reply` similarly publishes at most one typed reply to the
-principal's canonical inbox. `st2 request status --json` returns the tagged
-union `pending | replied`, suitable for a durable workflow to observe between
-its own durable waits. st2 provides no wait loop or timer and does not turn the
-request into agent lifecycle authority.
-
-This transport is design-superseded but still normative for the shipped
-implementation: [`0004-stream-events-are-a-distinct-record-kind`](.decisions/0004-stream-events-are-a-distinct-record-kind.md)
-absorbs typed requests into stream events plus ordinary replies, staged behind
-a deprecation window ([04-stream DQ-S4](04-stream/open-questions.md)). Until
-that staging completes, this section and its invariant row remain the truth;
-the drift is fenced by
-[DELTA-002](.delta/DELTA-002-typed-request-absorption-pending.md).
-
-## Resource bindings (R20-R21)
-
-An agent may directly declare zero or more generic Resource bindings:
-
-```kdl
-resource "work" uri="github-issue://example/project/123" reason="release work item"
-```
-
-The positional name is an agent-local semantic role. `reason` explains why the
-reference belongs to this agent (required; optional `inactive-reason` retains
-inactive bindings). `uri` is the exact RFC 3986 absolute Resource identity,
-preserved byte-for-byte without normalization. Declaration order has no meaning
-and binding names are unique within one agent. A Resource URI may be referenced
-by any number of agent declarations. The public `agent-spec` read model
-preserves the bindings in name order across canonical KDL and the supported
-TOML/JSON forms. `st2 agents --json` projects the same descriptors for
-language-neutral inspection.
-
-The generic binding envelope does not register schemes, resolve targets, infer
-authority from URI possession, or attach required/optional, access, readiness,
-or lifecycle semantics. Its scheme is, however, the exact lookup key for an
-optional catalog-declared Resource Profile. The built-in registry is empty;
-unregistered schemes stay opaque. Registered schemes resolve through the
-feature-gated wasm-only SDK boundary specified by
-[`07-resource-profile`](07-resource-profile/spec.md) and may supply a contained
-local path plus resync notification class. Scheme semantics and profile modules
-remain downstream-owned.
-
-A Resource binding and its optional resolution are declaration/observation
-metadata and are absent from task launch targets. Changing only Resource
-bindings adopts an already-live task without stop, replacement, or relaunch.
-Read-oriented renderer integration remains tracked in
-[st2#61](https://github.com/compoundingtech/st2/issues/61), and the portable
-Agent Spec envelope in
-[evals#41](https://github.com/compoundingtech/evals/issues/41).

-## Transactional catalog authoring
-
-`st2 agent digest (--spec FILE | --bundle DIR)` captures a source through
-retained no-follow file descriptors and returns its authoritative digest.
-`st2 agent publish --catalog ROOT (--spec FILE | --bundle DIR)
---input-sha256 HEX (--expect-absent | --expect-sha256 HEX)
-[--managed-by MARKER] --json` binds publication to that exact capture.
-`--expect-sha256` is the target Agent Spec leaf CAS. Publication accepts exactly
-one canonical KDL `agent` node with an explicit ID plus path-safe host and identity.
-st2 no longer exposes an intent compiler: external
-renderers own the transformation from human intent to exact Agent Spec bytes or
-a create-only publication bundle.
-
-The persistent `<catalog>/.st2/catalog-authoring.lock` defines one cooperative
-read/write transaction domain:
-
-```text
-publisher (EX)  : snapshot input -> CAS -> full-catalog admission -> atomic publish + fsync
-reader (SH)     : discover -> materialize/observe -> plan -> execute
-bulk apply (EX) : root CAS -> durable stage+marker -> converge -> verify+clear
-state plane     : message | context | Resource | status                    (unlocked)
-```
-
-Every publication temporary, including a not-yet-visible identity bundle, is
-staged under `.st2`. Cross-directory rename therefore stays on the catalog
-filesystem while a crash can leave debris only in the non-projected control
-plane; declaration directories never contain writer-private leaves.
-
-Before a declaration writer mutates the live projection it durably creates
-`.st2/catalog-generation-incomplete`. Shared declaration readers and read fences
-fail closed while this intent exists. After the declaration and its parent are
-durable, the writer advances and fsyncs `catalog-generation`, then clears and
-fsyncs the intent. The next exclusive writer recovers an orphan intent by
-conservatively advancing the generation before clearing it. A crash after the
-advance but before intent removal may therefore skip a generation on recovery;
-the contract is monotonic change detection, not an exactly-once counter.
-
-The resident supervisor watches the parent of `catalog-generation` through a
-dedicated non-recursive backend instance. Atomic replacement of the generation
-file queues one unit wake only after the transaction has made its declaration
-durable. The shared catalog lock still fences the following pass from an
-in-progress writer. This constant-cost commit channel is independent of the
-declaration-space watcher, so declaration subscription volume or failure cannot
-delay a successful st2 publication until the full-audit timer.
-The supervisor records the control-directory identity for that subscription.
-If the directory is replaced, the next pass diagnoses the stale subscription
-and installs a watcher on the replacement directory.
-
-The lock file is a persistent real inode: replacing or removing it would split
-the lock domain for a process that already has it open. Consequently, the first
-coherent declaration reader may initialize exactly `.st2` and this lock even
-when its requested operation later refuses. Refusal still performs no
-declaration, workspace, or state mutation.
-
-The publisher derives the destination from the captured declaration, replaces
-only `agent.kdl` for a hash-authorized update, and preserves all sibling runtime
-state. A bundle is create-only and is renamed from a hidden same-filesystem
-stage; retry reports `unchanged` only when every projected bundle file already
-matches. `--expect-absent` is idempotent for identical input.
-
-A hash-authorized update also passes the ownership boundary the lifecycle verb
-applies, because it rewrites the same declaration wholesale. `--managed-by
-MARKER` asserts the ownership marker the caller believes owns the incumbent,
-and the replacement is admitted only when the incumbent's own
-`meta { managed-by "..." }` names exactly that one marker; a mismatched marker,
-an unmarked incumbent, an unresolvable multi-marker incumbent, and an empty or
-padded assertion each refuse before any write, under the same refusal codes the
-authoring verbs use. Without an assertion, only the Nix marker refuses, which
-is what lets each publisher of another marker adopt the assertion on its own
-schedule. Create-only publication has no incumbent to protect and a
-byte-identical republication authors nothing, so neither requires an assertion;
-a candidate that merely claims a marker asserts no authority, and the receipt
-reports `managedBy` only for a marker the incumbent confirmed. Incumbent bytes
-that are not readable as a declaration carry no ownership claim, so repairing
-them stays possible for a writer who could already replace the file directly.
-
-Admission separates declaration structure from ambient launch readiness. Parsing, identity and
-topology checks, path expansion and authority, render grammar and workspace-relative destination
-safety, and delivery shape/coherence are lifecycle-independent. Running and suspended subjects
-occupy their effective host-local address; retired subjects do not. Only a running subject requires
-resolved paths and copy sources to exist, a service to have runnable work, provider overlays and
-hook sets to be available, delivery readiness to be present, and its prospective PTY socket to fit
-the host's portable bind limit. Suspended and retired subjects do not resolve Resource bindings or
-Resource Profiles and do not project render-input existence as an ambient fact. Transitioning one
-of those declarations to running restores every readiness check before materialization or launch.
-
-Host-scoped validation rejects a running pty task whose session socket path would exceed the
-portable `sun_path` bound. `pty` binds `<PTY_ROOT>/<session-id>.sock` and refuses a
-bind over the limit, so such a running task can never spawn and fails identically on every
-reconcile pass, which also makes the pass result useless as a health signal for that
-host. The bound is derived from the pty root resolved for the RUNTIME catalog — the
-one the supervisor will bind sockets from — and never from the tree under inspection,
-which is frequently a different tree: publication admits a candidate through a
-disposable projection nested in the catalog, transactions validate captures and stages,
-and a retained catalog is addressed through a file-descriptor path that canonicalizes
-back to the real one. A caller that knows where sockets will be bound supplies that
-root; only a deliberately context-free validation omits the guard. Measuring the
-inspected tree instead charges every identity for the depth of whichever temporary tree
-is being validated and refuses declarations whose real socket is bindable. The bound is
-never a fixed maximum identity length either: the usable identity length is what
-remains of the limit after the runtime root. The portable 104-byte bound applies so a
-declaration admitted on Linux does not fail on Darwin, and the diagnostic states the
-resolved path and the byte overage so the author can shorten the identity rather than
-discover the failure as a spawn error later. Suspended and retired PTY declarations
-bind nothing and are accepted regardless of prospective socket length; activation
-re-runs the bound before launch.
-
-A park notice whose cause is structurally unrecoverable says so instead of offering
-`st2 unpark`, which would relaunch into the identical failure. The test is the same
-predicate admission uses, not the wording of a spawn error.
-
-Before returning success, publication reads the exact live declaration back under the catalog
-lock, verifies its digest and bytes, and re-admits the live catalog. `st2 validate --candidate
-FILE --json` emits the ordinary `st2.validate.v2` Report semantics. Successful JSON publication
-emits `st2.agent-publish.v2`. Both identify the `st2.core+catalog.v1` policy profile and the same
-`agentSpecRevision`. A clean hermetic build uses the complete 40-hex source revision; dirty or
-revisionless local builds use explicit identities that cannot compare equal to a clean hermetic
-receipt. The byte-only `st2 agent digest --json` contract remains
-`st2.agent-source-digest.v1` because it makes no parser or policy claim.
-
-`st2 catalog snapshot --catalog ROOT --output DIR --json` holds SH while it
-captures the canonical declaration projection: `catalog.kdl`, exact
-`agents/<host>/<identity>/agent.kdl` files, static files inside those bounded
-agent bundles, and every regular file in `_templates` whether or not a current
-render references it. `_templates` is bounded to depth 8 below its root, 256
-files, 1 MiB per file, and 32 MiB total; symlinks, hard links, special nodes,
-and reserved control/state names are rejected. Runtime state, `.git`, `.st2`,
-the native `pty` registry, and workspace content are excluded. A
-catalog-contained Agent `workspace` or Task `cwd` is valid only when it names
-that agent bundle's canonical real `.workspace`; the empty directory itself is
-an exact declaration fact, while its descendants are never traversed. The
-classification uses launch-equivalent variable expansion, resolves relative
-values from the Agent Spec bundle, and lexically normalizes before comparing
-against the logical catalog. A relative spelling is accepted only when it
-normalizes to that bundle's canonical `.workspace`; unresolved variables and
-every other effective relative path fail closed. The
-scanner always excludes a canonical `.workspace` subtree, including an orphan
-left after an agent move or removal. External workspaces remain valid and are
-not part of the projection. The output is a create-only durable directory; an
-identical retry is `unchanged`. Its domain-separated, path-sorted root SHA-256
-covers normalized relative paths, file bytes, executable bits, and empty
-workspace directory facts.
-
-`st2 catalog snapshot --catalog ROOT --output DIR --raw-preimage --json`
-externalizes a byte-oriented CAS preimage. Under the same shared lock it
-structurally captures `catalog.kdl`, canonical
-`agents/<host>/<identity>/agent.kdl` leaves, their bounded static bundle files,
-the bounded `_templates` tree, and existing canonical `.workspace` directory
-facts without parsing declaration bytes. The ordinary state/control exclusions
-still apply. Every captured input must be a safe real file or directory with no
-symlink or hard-link alias. No live validity, catalog-envelope, profile, or
-effective PTY-root assertion exists in this mode. Its root uses the distinct
-`st2.catalog-raw-preimage-root.v1` hash domain and the receipt schema is
-`st2.catalog-raw-preimage-snapshot.v1`; it is not interchangeable with a strict
-snapshot root. Create-only retry rechecks both the raw root and output link
-counts.
-
-`st2 catalog diff --catalog ROOT --prepared DIR --expect-sha256 HEX --json`
-holds the existing authoring lock in shared mode and performs no initialization
-or publication. It projects and fully admits the coherent live catalog, rejects
-unless its declaration root equals `HEX`, captures `DIR` through retained
-no-follow capabilities into private temporary storage, then projects and fully
-admits that capture against logical `ROOT`. Any malformed, ambiguous, stale,
-symlinked, hard-linked, special, reserved, or unprojected input fails without a
-partial JSON receipt.
-
-The typed result is:
-
-```json
-{
-  "schema": "st2.catalog-diff.v1",
-  "catalog": "/catalog",
-  "prepared": "/prepared",

-
-Path changes are ordered lexically and use `added`, `removed`, or `modified`.
-They describe projected-fact changes: file content, executable bit,
-classification, or workspace-fact presence. A missing `before` side for an
-addition and a missing `after` side for a removal serialize as `null`; a
-modified path has both sides. Each present side classifies the fact as
-`catalog`, `agent-spec`, `render`, `template`, `static`, or `workspace-fact`.
-File content remains private and only the existing aggregate declaration roots
-are hashed in the receipt.
-`render` means a catalog-owned bundle file consumed by a normalized render
-operation of a running declaration, while `_templates` remains `template` even when referenced.
-An inactive declaration's existing bundle input remains `static`; its missing input is not resolved.
-
-Agent fields lower through the shared Agent Spec model and ordered render-plan
-parser. This is model-field normalization, not resolved effect normalization:
-physical source paths, comments, formatting, map order, and explicit spellings
-of effective defaults disappear, while accepted `workspace`, task `cwd`, and
-render path strings remain exact model values. Task addresses include both kind
-and name. Dynamic JSON Pointer segments use RFC 6901 escaping; for example,
-environment key `A/B~C` becomes `A~1B~0C`. The address necessarily exposes the
-host, identity, task/resource names, and environment/tag keys needed to locate
-the field. Render operations retain their declaration order, while
-`json-upsert` object keys normalize before comparison. A changed field reports
-only `absent`, `default`, or `present` plus its type; inclusion in `fields`
-proves the two normalized payloads differ. Payload values, lengths, and
-per-field or per-agent hashes are never emitted.
-
-`paths` describes projected-fact changes, so a formatting-only source
-edit may modify `agent.kdl` while `agents` remains empty. An empty `agents`
-array is normalized agent equivalence, not byte identity. The command does not
-decide whether a change is safe, select agents for migration, inspect a PTY
-registry, or authorize apply.
-
-`st2 catalog digest --catalog ROOT --prepared DIR [--json]` performs the same
-retained no-follow capture and desired projection as apply without taking the
-catalog lock or mutating it. Its `st2.catalog-digest.v1` receipt carries the
-canonical catalog and prepared paths plus `rootSha256`, the capability passed as
-`INPUT_HEX`. This command exists for invalid-incumbent repair, where semantic diff
-cannot parse the live side; ordinary apply callers reuse the diff receipt's
-`afterRootSha256` rather than making a redundant capture.
-
-`st2 catalog apply --catalog ROOT --prepared DIR --input-sha256 INPUT_HEX
---expect-sha256 HEX --json`
-rejects any prepared state/control path, symlink, special node, unprojected
-file/directory, malformed declaration, nonempty prepared workspace fact,
-catalog-local/default PTY root, or effective PTY-root change. Hash-CAS captures
-and validates exact prepared bytes, rejects a captured declaration root unequal
-to `INPUT_HEX` before taking EX or mutating catalog state, takes EX, rechecks the canonical live root,
-and either reports `unchanged` for exact equality or creates a durable
-content-addressed stage before publishing the marker. Version 1 requires an
-explicit PTY root outside the canonical catalog. Hash-CAS permits declared live
-workspace facts and their real ancestry to contain content. It changes
-declaration leaves only; a desired workspace fact is runtime-only, so the
-prepared plane need not carry its directory — a raw preimage captures none of
-them — and the transaction publishes any missing one as an empty directory.
-Workspace content and canonical state are never traversed, deleted, or hashed.
-When an identity path is absent, its complete bundle uses an exclusive
-directory rename. When its declared workspace skeleton already exists, the
-durable marker fences declaration readers and marker-time state routing until
-every declaration leaf has been published and verified. Applied leaves and
-their parents are fsynced, the live root is re-hashed and fully admitted, then
-the marker is unlinked and `.st2` is fsynced.
-The catalog parent is fsynced when `.st2` is first created, including the
-concurrent create/observe race. Retained source capture rejects a staging
-destination contained by its source before enumerating that source.
-
-The lock file is never removed: replacing its inode would split the transaction
-domain for processes that already hold it open. Reconciliation holds SH from
-discovery through execution. Validation, doctor, roster, listing,
-materialization-only, targeted reconciliation, and catalog teardown take a
-coherent SH snapshot. State-plane commands deliberately do not: their atomic
-files remain live while a declaration is admitted.
-
-`<catalog>/.st2/catalog-apply-incomplete` is the durable whole-catalog
-transaction fence. Any presence is authoritative, including malformed content.
-The reserved canonical record is:
-
-```json
-{"schema":"st2.catalog-apply-incomplete.v1","stageName":"catalog-apply-stage-<prepared-root-sha256>","expectedRootSha256":"<previous-root-sha256>","preparedRootSha256":"<prepared-root-sha256>","originalPaths":["<sorted-owned-declaration-leaf>", "..."]}
-```
-
-After taking its authoring lock, st2 refuses publication, validation,
-materialization, teardown, roster, doctor, and catalog listing while the marker
-exists. One-shot and selected reconcile fail explicitly. A resident supervisor
-instead remains alive, reports a skipped/incomplete pass, and performs no
-runtime observation or lifecycle action, avoiding a service restart storm.
-Message, context, Resource, and status operations remain available. While the
-marker exists, exact agent-ID operations resolve canonical state from a
-validated subject book: the marker's original canonical agent IDs union the
-currently published real specs. Ordinary address operations resolve against
-the corresponding coherent original-or-current address binding for that
-subject and fail when the marker cannot prove one unique binding. The marker
-therefore retains or content-addresses enough original declaration evidence to
-recover both ID ownership and effective address; it never guesses from a
-dotted string. State-only directories are addressable only for original IDs
-with recognized real state; an incomplete or arbitrary new ID does not fall
-back to a flat bus. Every host, agent ID, and message-box path is opened
-component by component without following symlinks, and state mutations remain
-relative to those retained capabilities. Only real state directories and a
-real regular status file can establish marker-time addressability. Only
-`catalog apply --resume --catalog ROOT --json` may open an existing marker. The
-closed marker and internal content-addressed stage are
-sufficient recovery authority; the original prepared path, input digest, and incumbent CAS
-precondition are neither required nor consulted. The marker's `preparedRootSha256`
-is the input digest already proven against retained capture before publication.
-Marker authority proves both original preconditions already passed, so recovery converges the partial live tree from
-the durable desired stage and original owned-leaf list without re-enforcing
-that stale precondition. Malformed or mismatched records remain fenced.
-External lock execution and bypass flags are not part of the contract.
-
-`st2 catalog apply --catalog ROOT --prepared DIR --input-sha256 INPUT_HEX --expect-sha256 HEX
---raw-preimage --json` is the only writer that accepts the raw-preimage root.
-It first captures and fully admits `DIR` through the ordinary strict prepared
-projection. Under EX it structurally reprojects the opaque live declaration
-plane and checks its raw-domain root against `HEX` before any declaration,
-workspace, state, writer-temporary, marker, or stage mutation. It never parses
-or semantically validates the live bytes, including their catalog envelope,
-profiles, validity, or effective PTY root. A successful CAS reuses the ordinary
-durable stage, generation commit, leaf publication, strict live verification,
-and fsync sequence. Its receipt schema is
-`st2.catalog-raw-preimage-apply.v1`; its durable marker schema is
-`st2.catalog-raw-preimage-apply-incomplete.v1`. The marker schema preserves the
-projection type, so source-free `--resume` emits the truthful raw-preimage
-receipt after converging from the strictly validated stage. This mode owns no
-policy for interpreting or transforming incumbent bytes.
-
-`st2 catalog bootstrap --catalog ROOT --prepared DIR --input-sha256 HEX --json`
-is the create-only declaration transaction for an absent catalog. `ROOT` must
-be one absent final component below an existing canonical real parent. st2
-captures `DIR` through retained no-follow capabilities, verifies its declaration
-root against `HEX`, admits the complete projection against logical `ROOT`, and
-requires one explicit external PTY root. It materializes a 0700 sibling stage,
-creates the persistent authoring lock and generation `1` inside it, takes EX on
-that lock, fsyncs the complete tree, and publishes it with a capability-relative
-no-replace directory rename followed by a parent fsync. Readers therefore see
-absence or a complete catalog and cannot cross the already-published lock before
-the parent entry is durable.
-
-There is no bootstrap marker or resume mode: interruption before the rename
-leaves `ROOT` absent, while interruption after it leaves the complete target. A
-retry re-captures its source and returns `unchanged` only after taking the
-existing lock, rejecting incomplete markers, proving a durable generation,
-fully validating the catalog, matching the exact declaration root, proving the
-locked directory remains bound to `ROOT`, and fsyncing the retained parent. A
-different, malformed, symlinked, rebound, or uninitialized existing target fails
-without mutation. Random sibling stages are non-authoritative and are cleaned
-only by the invocation that created them; no broad orphan cleanup is permitted.
-
-Bootstrap performs zero reads or writes below the declared PTY root. The PTY
-registry has independent producers which catalog EX cannot reserve, so atomic
-process adoption, continuity, or PTY-root migration requires a separate PTY
-registry protocol. Bootstrap claims only atomic declaration publication.
-
-## On-demand residency (R44-R46)
-
-Desired lifecycle and runtime residency are independent:
-
-```text
-desired state:      running | suspended | retired
-residency policy:   always | on-demand
-runtime residency:  active -> quiescing -> stopping -> cold
-                                 demand waits |          |
-                                              `-> starting -> active
-```
-
-The canonical declaration is `residency-policy "on-demand"`; omission and
-`"always"` are semantically equal. On-demand policy requires a native session
-driver. It grants eligibility only while desired state is running. A transition
-to suspended or retired hands ownership back to ordinary desired-state
-reconciliation rather than adding a second desired lifecycle.
-
-Runtime residency is recorded in one
-`st2.residency-ledger.v1` host-local record keyed by the immutable agent ID and
-host. The record carries the native driver, a positive generation, the closed
-runtime-residency state, and whether external demand was observed during a
-transition. It does not carry message filenames, delivery attempts, native
-session identifiers, or process observations. Those remain authoritative in
-the inbox and delivery ledger, provider binding, and task inventory.
-
-Every transition is generation-fenced. After idle confirmation, the monotonic
-order is checkpoint native session, stop the complete owned task group, verify
-absence, and become cold. Demand observed after checkpointing sets a durable
-wake-pending fact but does not cancel teardown. A cold or newly absent runtime
-then prepares exact native resume, launches the owned group, verifies the saved
-native session, and becomes active. A mismatch, unsupported driver capability,
-indeterminate presence, malformed ledger, or foreign ownership becomes a
-fail-closed refusal. No path substitutes a fresh session.
-
-For Claude, the provider binding owns the exact native UUID, wrapper incarnation,
-canonical workspace, transcript path, and optional resume generation. Checkpointing
-first resolves the UUID to exactly one file in the active managed Claude
-transcript store, rejects a matching Codex transcript, opens the file with
-`O_NOFOLLOW`, requires a regular `<uuid>.jsonl` file, validates every recorded
-`sessionId`, derives one rooted workspace lineage, and stores the SHA-256 of
-the exact bytes. Resume revalidates that lineage and digest before any provider
-child starts, rejects authored
-session selectors, and lowers to `claude <options> --resume <uuid> -- <prompt>`.
-Ordinary launches also use the option terminator and explicitly remove inherited
-residency fence variables.
-
-The synchronous `SessionStart` observer is Claude's native identity proof.
-Ordinary observation remains fail-open. During mandatory resume, observer setup,
-payload validation, transcript validation, and durable candidate publication
-propagate failure. The hook stores the candidate under the new wrapper
-incarnation and resume generation without replacing the checkpoint binding.
-After complete-group presence establishes the current wrapper incarnation,
-exact native-session verification promotes only that incarnation's candidate.
-A failed start therefore leaves the checkpoint
-retryable. A later explicit in-process session switch becomes the next
-authoritative binding and does not inherit the consumed resume fence.
-
-`st2 tasks --json` uses schema `st2.task-inventory.v3`. Each task row appends
-`residencyPolicy` and nullable `runtimeResidency` beside the existing process
-`runtime` observation. A missing ledger is `null`, never inferred as active or
-cold. A malformed, unsupported, or wrongly owned ledger makes the inventory
-incomplete and reports the error without mutating state.
-
-The first wake authorities are an unread durable inbox message and an explicit
-operator wake or attach request. Passive CPU, filesystem access, PTY attachment
-state, and Resource observation are not demand. Host policy owns idle thresholds
-and warm capacity. Telemetry measures resume-to-ready and demand-to-delivery
-latency before the project assigns a latency objective.
-
-The folder-catalog supervisor enables this policy only when `st2 up` receives
-both `--residency-idle-after <duration>` and
-`--residency-warm-capacity <count>`. If a catalog contains a running on-demand
-agent and the host omits this policy, reconciliation holds that agent
-`adopt-only` and reports an error instead of launching it. `st2 wake` writes an
-explicit durable wake request. `st2 pty attach <agent-address>` writes the same
-request before attaching. Each launch attempt has a host-minted incarnation
-fence. A retry after a missing provider rotates this fence. A live provider
-retains the fence while reconciliation completes its sidecars. Provider
-readiness must match the independent fence, so a binding left by an earlier
-failed attempt cannot make a later attempt active. A wake request that races
-with checkpoint or stop remains pending until the complete task group is absent
-and exact native resume can start.

-- **R01–R03:** Fleet validation separates structural errors from selected-host
-  runtime facts. Materialization is inspectable and host reconciliation starts
-  only declarations pinned to the local host. Discovery is recursive: an
-  explicit `identity` and `host` pair is authoritative independent of the
-  declaration's path, whose parent remains the state/resource anchor. When
-  either field is omitted, the path supplies defaults and mismatches remain
-  diagnostic. Dot-prefixed folders, including `.managed` and `.retired`, are
-  ordinary declaration space; only `.git` and `.st2` directories at any depth,
-  the catalog root's `pty` child, and a declaration parent's `resources`,
-  `archive`, and `inbox` children are excluded.
-  A resolved workspace-relative render destination has one coherent desired
-  state across the active local fleet: byte-equivalent idempotent claims may
-  share it, while incompatible
-  claims fail every conflicting owner before the first workspace write.
-  Targeted reconciliation checks the selected owner against the full fleet, so
-  selection cannot bypass this ownership boundary.
-- **R04, R31:** Each machine schedules and reconciles only its pinned work. The st2
-  loop is deterministic; exactly one declared root agent provides intelligent
-  host-local supervision, bounded recovery, and escalation. Filesystem reads
-  never wake reconciliation; only create, modify, rename, or remove events may
-  wake it before the bounded timer. A generated companion is eligible only
-  while its canonical agent task is eligible. Healthy startup launches the
-  agent first and then its missing companions in the same pass. Holding or
-  failing to restart the agent, or terminally parking it, suppresses companion
-  launch and stops an exact generated companion proved live; explicitly
-  authored sibling tasks remain independent.
-  Restart accounting is per task and persists across reconcile passes. Only a
-  successful launch spends its declared budget. Each completed pass supplies
-  the exact task IDs it proved alive; uninterrupted observed liveness may
-  forgive a fail-mode budget according to the
-  [restart field contract](./02-agent-spec/spec.md#f12-future-policy-r31), while an unobserved task
-  loses accrued recovery uptime. A pass that exits before execution neither
-  supplies a liveness observation nor closes the accounting pass.
-  [PR #191](https://github.com/compoundingtech/st2/pull/191) provides cadence,
-  recovery, and unobserved-pass evidence for this accounting.
-- **R32:** Bounded non-interactive helpers such as `pty list --json` and
-  `pty metadata patch` start in a fresh session whose leader PID is also its
-  process-group ID. Standard output and error use regular temporary files, so a
-  descendant inheriting those descriptors cannot hold a capture pipe open.
-  After spawn, an input setup or write failure or a deadline expiry sends
-  `SIGKILL` to the process group and explicitly terminates the direct child.
-  st2 waits for that child until the cleanup deadline; if it cannot finish the
-  wait synchronously, a background waiter takes ownership before the failure
-  returns. The process-group signal reaches a descendant that outlives the
-  direct child; terminating the direct child alone does not. [PR
-  #202](https://github.com/compoundingtech/st2/pull/202) provides
-  descendant-lifetime and direct-child-reap evidence for this contract.
-- **R39:** Spawn ownership is a closed two-case lifetime choice:
-
-  - `DetachedTask` is the existing production PTY/exec task generation.
-    Detachment through the PTY daemon or `setsid` keeps it outside the
-    supervisor's ownership group. Supervisor return, unwind, replacement, or
-    `SIGKILL` therefore leaves its PID and creation identity unchanged; only an
-    explicit down, retirement, replacement, or other reconciliation action may
-    stop it.
-  - `OwnedChildGroup` is an integration/evaluation harness child that must not
-    outlive its parent. The owner first starts a
-    watchdog as leader of a fresh process group, then joins the child to that
-    exact group. Keeping the watchdog in the group pins the group ID until
-    cleanup has signalled it, so a stale numeric PID cannot redirect teardown
-    to a later process.
-
-  The owner and watchdog hold opposite ends of a Unix socket pair. Only the
-  owner retains the write end; it is close-on-exec and the child closes its
-  inherited descriptor before exec. Normal return and Rust unwind run the
-  guard's `Drop`, which sends `SIGKILL` to the exact group, closes the
-  liveness channel, and reaps the direct child and watchdog. Cleanup polls for
-  at most two seconds; any waits still outstanding are moved to a background
-  reaper before control returns. If the parent dies before `Drop`, socket EOF
-  releases the in-group watchdog, which sends `SIGKILL` to its own group.
-  Descendants inherit group membership and are included. After hard parent
-  death the kernel reparents and the host init/subreaper reaps the now-orphaned
-  processes; synchronous wait by the dead owner is impossible.
-
-  This hard-death realization is supported on the Unix hosts st2 targets; it
-  does not claim a Windows job-object equivalent. The executable regressions
-  are
-  `tests/catalog_apply.rs::paused_catalog_child_is_reaped_when_test_unwinds`
-  for unwind cleanup and
-  `tests/eval_up.rs::owned_test_child_group_dies_after_hard_parent_death` for
-  socket-EOF group cleanup. The control in
-  `tests/eval_up.rs::st2_up_spec_supervises_and_respawns_a_killed_agent`, plus
-  the forced-kill cases in `tests/nomad_survival.rs`, proves that an owned
-  supervisor child is cleaned without absorbing the detached production task.
-- **R06:** st2 passes the complete effective task definition to the underlying
-  launcher so manual and supervised restarts are equivalent. Harness readiness
-  that depends on a dynamically selected account belongs to that declared
-  command. In particular, reconciliation never mutates an ambient Codex config
-  before launch: the command may select an account-specific `CODEX_HOME` only
-  after st2 starts it. `st2 pretrust` remains an explicit operator utility for
-  commands that intentionally use the ambient Claude and Codex configs.
-
-  st2 owns `ST_AGENT` for every PTY and exec task, setting it to the
-  catalog-global immutable agent ID on every reconciliation. Compact agent
-  lowering assigns that ID explicitly to its canonical task. Other named tasks
-  without explicit IDs append `.<task-name>`, including a task named `agent`.
-  The resolved host remains a separate declaration and launcher input; it is
-  not separately concatenated into either derivation, and any host-looking bytes
-  inside a legacy ID are opaque. An omitted `ST_AGENT` is injected, an authored
-  exact match is accepted, and a conflicting authored value refuses the
-  declaration before workspace materialization or runner access. The value is
-  part of the persisted launch environment, so initial launch, supervised
-  replay, and manual PTY restart preserve the same actor ID.
-
-  The canonical `agent` task treats a reconciler's ambient `NO_COLOR` as a
-  launcher preference rather than agent policy. Unless the Agent Spec declares
-  `NO_COLOR`, the runtime removes it from the launch environment and records the removal
-  in the PTY launch definition. An explicit Agent Spec assignment takes
-  precedence. Isolation wrappers preserve both assignments and removals, so a
-  manual PTY restart under a different ambient environment reconstructs the
-  same effective color policy. Adoption of an already-live task remains
-  non-mutating: this policy is applied only when st2 creates a generation.
-- **R42:** [Launch argv](ontology.md#launch-argv) is opaque at every
-  st2-added wrapper boundary. Generated environment arguments name variables,
-  not their values. In Linux systemd scope mode the exact outer command order is:
-
-  ```text
-  systemd-run --user --scope --collect --quiet --no-ask-password --unit=<unit> "--description=st seat" --expand-environment=no -- <program> <arg>...
-  ```
-
-  On systemd v236–253, omit `--expand-environment=no`: those versions execute
-  scope argv directly and do not implement the option. Unknown or older
-  versions, or an unavailable user manager, select degraded isolation. Literal
-  percent and dollar bytes remain unchanged on both paths.
-
-  On v254+, `--expand-environment=no` is an outer `systemd-run` option immediately before
-  the `--` separator. `<program>` and every `<arg>` are appended as their
-  original OS strings, without shell rendering, dollar escaping, or
-  environment substitution. Detached and degraded-detached modes remain
-  `<program> <arg>...` pass-throughs with no outer command.
-
-  Launch environment values reach the task through the process environment the
-  wrapper inherits: the PTY launcher receives name-only `--env <NAME>` flags
-  and resolves each value from that environment, so a service manager or
-  process listing records names only for those generated environment flags.
-  The resolved managed overlay still wins over the launcher's environment;
-  the shared `PTY_PLACEMENT_ENV` set identifies `PTY_ROOT` and the deprecated
-  `PTY_SESSION_DIR` as runtime-owned controls. The runtime-selected `PTY_ROOT`
-  wins, and `PTY_SESSION_DIR` is removed after the overlay (including inherited
-  values). Declared legacy placement is ignored with a name-only diagnostic.
-  Spawn and observation share a registry; other member-environment precedence
-  is unchanged. Captured launcher output is classified privately. PTY launch
-  failure reasons contain a closed diagnostic kind plus exit status, never
-  captured text that could echo environment values into replicated claims or
-  traces. The kinds, in matching priority order, are:
-
-  - `launcher-incompatible`: the older name-only-rejecting `Invalid env format`
-    / `Use --env KEY=VALUE` diagnostic (not the new parser's name-only grammar).
-  - `placement-conflict`: conflicting canonical/legacy roots or an overlong root.
-  - `session-in-use`: the existing occupied-ID diagnostic; retry behavior remains
-    unchanged.
-  - `spawn-failed`: recognized daemon exit/start or publication-timeout diagnostics.
-  - `unknown`: anything unrecognized, including undecodable output.
-
-  These are diagnostic categories, not a guarantee of the underlying root cause.
-  No raw-output file or journal sink is added.
-
-  This mechanism does not sanitize explicitly authored argv or tag expansions.
-  Seat-declared environment values stored in replicated graph claims remain a
-  known exposure outside the command-line and unit-description fix.
-
-  `src/isolate.rs::tests::wrap_scope_disables_expansion_and_preserves_dollar_bearing_argv`
-  fixes the complete wrapper order and proves literal `$HOME`, `${UNSET}`, and
-  `$$` after the separator.
-  `src/isolate.rs::tests::wrap_detached_modes_preserve_exact_program_and_argv`
-  proves both pass-through modes. `src/run/tests.rs::build_run_command_names_the_complete_managed_environment_without_its_values`
-  proves the managed environment is named without its values. The live-system
-  distinction and unaffected scope semantics are recorded in the
-  [systemd scope argv experiment](.experiments/2026-09-05-systemd-scope-argv-transparency.md)
-  and [`0016-systemd-scope-wrappers-disable-environment-expansion`](.decisions/0016-systemd-scope-wrappers-disable-environment-expansion.md).
-- **R07:** Hook bundles are explicit, content-addressed, installed separately,
-  and verified before materialization references them. Their receipts use the
-  same resolved build identity as the binary's version surfaces for both
-  hermetic package builds and source builds. Installation automatically accepts
-  an ordered upgrade; `--replace` is the explicit exact-state authority for a
-  downgrade, an unorderable build, or an unreadable receipt. Shipped hooks
-  resolve Bash through `PATH`; the Nix package executes their integration gate
-  with Bash and `jq` declared. Runtime materialization verifies the invoking
-  binary's own content-addressed set, independent of which installed binary the
-  receipt currently selects, so old and new supervisors can overlap during
-  cutover. `hooks verify-own` exposes that read-only capability to package
-  activation tooling.
-- **R11:** `st2 up` is a replaceable control plane, not the lifetime owner of
-  its agents. Normal exit, forced termination, binary replacement, and restart
-  leave every running agent PID and creation identity unchanged. The new
-  control plane adopts those processes and starts only missing work; it does
-  not duplicate them. Agent stop or retirement requires a separate explicit
-  lifecycle action.
-
-  Executable acceptance starts an agent, terminates `st2 up` normally and with
-  a forced kill, verifies the agent remains alive and usable, replaces the st2
-  binary, starts the control plane again, and proves adoption with the same
-  agent PID/creation identity and no duplicate process.
-
-- **Adopt-only migration fence:** A compact agent or explicit task may declare
-  `lifecycle "adopt-only"`. Reconciliation adopts an already-live generation,
-  but classifies a dead or absent generation as `held` without garbage
-  collection or launch. Returning the declaration to the default `service`
-  lifecycle is the explicit authority to resume ordinary replacement.
-  A non-running agent desired state remains the separate explicit teardown
-  path. Suspension and retirement never use task lifecycle as an implicit
-  resume or replacement authority.
-
-- **R23:** `st2 tasks --json` is a read-only diagnostic boundary. It emits one
-  `st2.task-inventory.v3` envelope for the selected host. Rows are sorted by
-  immutable agent ID, task name, and runtime ID and cover both PTY and
-  terminal-free exec tasks. Each row includes immutable agent ID, nullable
-  current bus address, declared residency policy, and nullable host-local
-  runtime residency; a proved non-routable retired subject has a null address
-  without weakening completeness. `complete=false` plus a non-zero exit is a
-  closed result: a consumer must not turn a missing row or residency record
-  into absence. A running row always carries a PID, creation time, opaque
-  generation ID derived from stable backend evidence, and the required
-  `runtime.resourceTarget`.
-
-  `resourceTarget` is internally tagged by `type` and has exactly these wire
-  shapes:
-
-  | `type` | Fields | Meaning |
-  | --- | --- | --- |
-  | `linuxCgroupV2` | `path` | The slash-prefixed unified-hierarchy path exactly as read from `/proc/<pid>/cgroup`; `/` is the cgroup-v2 mount root. |
-  | `darwinProcessTree` | `rootPid` | The observed generation's PID, used as a best-effort process-tree root. |
-  | `unavailable` | `reason` | No safe target: one of `notRunning`, `runtimeIndeterminate`, `processUnavailable`, `generationChanged`, `cgroupV2Unavailable`, or `unsupportedPlatform`. |
-
-  Linux accepts exactly one `0::<path>` entry. It preserves the path bytes
-  represented by UTF-8 text, including spaces and colons, but rejects a
-  non-absolute path, NUL or carriage return, repeated separators, trailing
-  separators, `.` or `..` components, duplicate unified entries, and input
-  with no unified entry. It does not derive the path from a systemd unit,
-  scope name, runtime ID, or naming convention.
-
-  PTY observation captures each candidate daemon's kernel process-start token
-  after the registry snapshot, then executes `pty stats --json` exactly once
-  without a session argument. The returned array is socket-backed live
-  evidence for every candidate. A token is admitted only when exactly one
-  stats row has the task name, `process.alive=true`, the same `daemon.pid`, and
-  the same `createdAt`, and a second kernel-token read equals the first.
-  Resource observation then reads the token before and after the target. Exec
-  compares those target-fence reads directly to the token already bound into
-  its generation record. A missing process is `processUnavailable`; a stats or
-  token mismatch, or a token that changes across a read, is
-  `generationChanged`. Neither result exposes the candidate path or root PID.
-  Darwin uses the same fence around its root PID. A bounded
-  `unavailable` target is a truthful successful field and does not by itself
-  make the envelope incomplete. Locators are sampled afresh on each command:
-  st2 stores no scope registry, performs no resource sampling, and gives no
-  target continuity guarantee. Runtime ID remains task identity.
-
-  Discovery runs before and after runtime observation. A semantic declaration
-  change across those passes makes the result incomplete. The reader also
-  samples `<catalog>/.st2/catalog-generation` and the incomplete marker around
-  discovery and runtime observation. Every successful declaration writer
-  advances and fsyncs that monotonic generation after its durable commit; apply
-  does so after live verification and before clearing its marker. Even a
-  completed declaration ABA is therefore incomplete. This remains an
-  observational seqlock and does not serialize catalog writers. A runtime root
-  positively absent at admission is empty and is not passed to its backend. An
-  admitted PTY root that is removed or replaced during `pty list` is
-  indeterminate; because the external backend creates an absent registry,
-  concurrent root deletion is not a zero-write boundary. Malformed state, PID
-  reuse, timeouts, duplicate ids, and observer failures are likewise
-  indeterminate. Existing plain-PID exec records are opened read-only without
-  following symlinks and verified by retained file identity, unchanged content
-  and metadata, the final path identity, process start token, and record mtime
-  without rewriting them. If that proof is unavailable on a supported OS, the
-  generation remains indeterminate.
-
-  Each row retains the task-level `desiredState` (`running` or `absent`) and
-  appends the declaration-level `agentDesiredState` plus
-  `agentDesiredStateReason`. The legacy `retired` boolean remains a projection
-  for compatible readers. `st2 agents --json` likewise appends `desiredState`
-  and `desiredStateReason`; presence remains an independent observed signal.
-
-  A believable parked-task projection is a known supervisor fault, not a
-  runtime state: the row retains its unmodified runtime observation and adds
-  the park time, reason, and explicit per-task recovery action while the
-  envelope remains complete. That action is structured `argv` containing the
-  exact canonical catalog folder and selected host observed by the inventory;
-  executing it does not consult ambient defaults for either ownership axis. An
-  unreadable, malformed, wrong-generation, or otherwise unbelievable park
-  marker is indeterminate and makes the envelope incomplete. The reader selects
-  only the marker channel owned by the exact canonical catalog folder and host
-  it is observing.
-
-- **R41/R28:** Agent lifecycle intent is one closed declaration state:
-  `running`, `suspended`, or `retired`. The KDL form is a direct child such as
-  `desired-state "suspended" reason="Waiting for capacity"`. Omission means
-  running. New suspended and retired states require a bounded rationale;
-  running forbids one. Legacy `retired #true` remains readable without a
-  rationale, but old and new lifecycle syntax cannot coexist.
-
-  Reconciliation treats both non-running states as desired task absence and
-  includes derived companions. Materialization skips them. Suspension is
-  converged when no task is live and only explicitly keep-pinned dead records
-  remain; retirement is complete only after every task record is absent.
-  Resume simply returns to ordinary task planning, preserving `keep`,
-  `adopt-only`, ownership, and replacement fences. Durable messages, context,
-  resources, and the declaration are not task runtime and remain available.
-
-  `st2 agent desired-state` performs one source-preserving canonical KDL edit
-  under the persistent catalog-authoring lock. The self/descendant trusted-fleet
-  guardrail matches presentation authoring. Running removes
-  lifecycle syntax; suspended and retired emit the canonical node. A success
-  receipt proves authored intent only. Reconciliation and Doctor separately
-  prove observed convergence.
-
-  Lifecycle is the one authoring verb a declaration's own generator may use.
-  Without an assertion, a Nix-owned declaration refuses exactly as before.
-  `--managed-by <marker>` asserts the ownership marker the caller believes owns
-  the declaration, and is admitted only when `meta { managed-by "..." }` names
-  exactly that one marker; a mismatched marker, an unmarked declaration, an
-  unresolvable multi-marker declaration, and an empty or padded assertion all
-  refuse. The
-  authority exists because a projection has exactly one transition its own
-  source cannot express: the source change being projected is the seat's
-  removal, so "edit the generated source instead" names an edit the operator
-  already made. A marker-matched edit therefore stands in for the
-  compare-and-swap `agent publish` a projection would otherwise perform.
-  Independently of marker authority, every desired-state mutation builds one
-  prospective shadow while holding the catalog-authoring lock. Admission
-  compares incumbent and prospective core `ERROR` identities as stable
-  `(code, catalog-relative path, agent)` multisets and refuses only positive
-  deltas; diagnostic messages are excluded because shadow paths make them
-  unstable. Thus retirement leaving an active agent descended from a retired
-  root refuses, entering running activates launch-readiness and address checks,
-  and entering suspended reacquires address and topology checks without
-  activating readiness. An unrelated pre-existing catalog error remains
-  admissible and can be repaired or torn down incrementally. The receipt records
-  the confirmed marker when marker authority was used. Presentation, address,
-  stream, and Resource authoring
-  keep the unconditional refusal: none of them projects a source the generator
-  cannot itself rewrite.
-
-  Inventory performs no reconciliation, launch, teardown, cleanup, lifecycle
-  edit, state migration, or catalog write. It does not authorize a staged
-  supervisor replacement; any cutover requiring transactional declaration
-  authority needs a separate protocol.
-
-- **Session registry:** A catalog owns the `pty` registry holding its tasks.
-  `<catalog>/pty` is the default; a catalog may declare another so that one host
-  can share a single registry across catalogs. Resolution is an exported
-  `PTY_ROOT`, then the catalog's declaration, then the default, applied
-  uniformly to spawn, list, kill, and the bus environment st2 hands to native
-  tools, so every reader that can resolve the catalog agrees about where its
-  sessions are. A declaration whose field set does not match fails `st2
-  validate` rather than resolving silently back to the default. Runtime
-  observation has a short outer deadline so a wedged client fails the pass
-  closed instead of hanging reconciliation. The deadline is containment, not
-  the mechanism for admitting a larger fleet.
-
-### Child-process execution (R32, R34)
-
-Non-interactive helper shells-outs (`src/run.rs`, `src/ding/mod.rs`) share one
-shape: the child is `setsid` so its pid is its process group, stdout/stderr go
-to unlinked tempfiles (an escaped descendant that inherited them cannot block
-cleanup), and deadline expiry kills the whole group. Wait ownership for a
-killed child transfers to one shared reaper thread draining a channel — never
-one detached thread per timed-out child, which accumulates without bound under
-timeout storms.
-
-Read-back is tail-capped at `CAPTURE_CAP_BYTES` (256 KiB) per stream: over-cap
-streams keep their last 256 KiB and emit one diagnostic line naming the
-command, stream, kept/total bytes, and cap. Memory per capture is therefore
-bounded by calls × 2 × cap regardless of child behavior. `pty list --json`
-parses structured output that must be whole, so it uses the explicitly named
-full-stdout variant; that read is intentionally uncapped and visible at its
-call site. Eval run steps and agent log dumps stream child output straight to
-their catalog log files without buffering it. Rationale and rejected
-alternatives: [`0007-child-output-capture-is-bounded-and-tail-preserving`](.decisions/0007-child-output-capture-is-bounded-and-tail-preserving.md).
-
-## Catalog graph and native delivery admission (R35–R38)
-
-Managed harness ownership is explicit. A declaration uses its typed driver or
-one `session-driver "claude|codex|pi|opencode|omp"` and pairs it with exactly
-one non-secret readiness declaration:
-
-```kdl
-delivery-readiness "credential"
-delivery-readiness "credential" account-id="tokengate/shared"
-delivery-readiness "anonymous" "model-a" "model-b" harness="omp"
-```
-
-Credential omission delegates account choice to the native driver. Anonymous
-readiness has at least one model; lowering sorts and deduplicates the model set,
-and `harness` must equal the effective native driver. A legacy `deliver` value
-must match that same explicit driver. No command-basename inference is
-admitted. A managed driver, readiness, or native delivery transport cannot
-coexist with Ding; Ding remains only for opaque non-harness PTYs.
-
-`st2 catalog graph --json` schema `st2.catalog-graph.v2` publishes
-`effectiveSessionDriver` and `deliveryReadiness` separately from `runtime`. It
-also publishes admitted topology:
-
-```json
-{
-  "parentId": "host.parent",
-  "rootId": "host.root",
-  "depth": 2,
-  "ancestorIds": ["host.parent", "host.root"]
-}
-```
-
-A root has null `parentId`, its own `rootId`, depth zero, and an empty ancestor
-array. Root counting folds retirement before the graph is built: a retired
-declaration — legacy `retired #true` or `desired-state "retired"` — is outside
-the org chart and never holds the root slot, while a suspended root still
-counts, so a host suspending its only root stays valid and a host whose every
-root is retired reports zero (#402). Duplicate identity, missing or ambiguous
-parent, cycle, depth beyond 64, or a host with other than one counted root is
-an error. An active agent whose chain terminates at a retired declaration is
-an error too (`retired-root`): the active org chart descends from the counted
-root, so one active root plus a retired root still supervising an active
-worker does not validate. Every affected topology field
-is null and the graph envelope has `complete: false`; downstream consumers use
-these admitted facts rather than walking supervisor edges themselves. The
-`declarations` view applies the same fold to legacy `retired #true`, publishing
-`desiredState: "retired"`; an absent lifecycle stays null, which lowers to
-running.
-
-The same envelope publishes every actor's resource root (R47) as a
-catalog-relative directory, the subject boundary under which the actor's
-declaration-anchored state, driver records, and `resources/` live. Both fields
-are appended to `st2.catalog-graph.v2` without a schema bump: a reader that
-ignores unknown fields reads the envelope unchanged, and neither field affects
-`complete`.
-
-```json
-{
-  "agents": [{ "id": "dev3.worker", "resourceRoot": "agents/dev3/worker" }],
-  "directActors": [
-    {
-      "id": "dev3.direct.omp.e2jcd9pf",
-      "host": "dev3",
-      "identity": "direct.omp.e2jcd9pf",
-      "ptyId": "e2jcd9pf",
-      "resourceRoot": "agents/dev3/direct.omp.e2jcd9pf"
-    }
-  ]
-}
-```
-
-Each `agents` row carries `resourceRoot`, its declaration's parent directory —
-the directory st2 itself resolves for that agent's inbox and context. A direct
-OMP actor has no declaration: its entrypoint derives
-`ST_AGENT=<host>.direct.omp.<encoded-pty-id>` from `PTY_SESSION`, and writers
-create `agents/<host>/direct.omp.<encoded-pty-id>/` lazily under that identity.
-`id` is byte-identical to that `ST_AGENT`. The `directActors` array lists every
-such directory across all hosts, sorted by host then identity. Direct actors
-never enter `agents`, and an archived one is an `archived` row like any other
-identity. Consumers fold per-actor views at these roots and never infer
-subject boundaries themselves.
-
-The PTY segment codec is shared with the dotfiles `agent-identity
-encode-pty`/`decode-pty` contract and is strict and reversible:
-
-| PTY session ID | Segment | Example |
-| --- | --- | --- |
-| PTY-generated: 8 characters from `23456789abcdefghjkmnpqrstuvwxyz` | the ID itself | `e2jcd9pf` → `e2jcd9pf` |
-| any other valid ID: 1–255 bytes of `[A-Za-z0-9._-]`, not `.` or `..` | `x-` plus its lowercase hex bytes | `web` → `x-776562` |
-| invalid ID | none; no identity exists | `a/b` |
-
-Decoding accepts only the canonical encoding of a valid ID: `x-` over a
-generated ID, uppercase or odd-length hex, and non-UTF-8 bytes all fail, so two
-segments never name the same PTY session and `ptyId` is exact. Discovery reads
-exactly two directory levels, `agents/<host>/<identity>`, and never descends
-into an actor's contents. An entry is a direct actor only when it is a real
-directory (a symlink is not), its name is `direct.omp.` plus a segment that
-decodes, and no declaration — parsed or failed — lives beneath it; a declared
-identity is a declared actor whatever its name looks like. Nothing reads names
-beyond the codec, cwd, process ancestry, activity, or mtimes.
-
-Retired reconciliation first attempts every live task teardown for the agent.
-Only when all of those attempts succeed does it settle the declaration's whole
-inbox; one failure leaves every inbox file untouched and the next pass retries
-teardown plus settlement. With no live tasks, settlement proceeds immediately.
-Each canonical inbox filename is linked into `resources/archive` and then
-removed from the inbox. An existing archive file wins byte-for-byte, so replay
-and a sync-restored duplicate converge without overwriting the receipt.
-Suspended reconciliation never performs this settlement.
-
-Retirement is where the lifecycle stops being about runtime and starts being
-about catalog size, so `st2 catalog archive` adds one step past it:
-`running → suspended → retired → archived`. Archival moves the whole identity
-directory from `agents/<host>/<identity>` into the catalog control plane at
-`.st2/archive/<host>/<identity>`, under the exclusive authoring lock and inside
-one generation commit, as a same-filesystem rename. `.st2` is excluded from
-catalog space at any depth, so an archived declaration is structurally
-undiscoverable and is never projected by a whole-catalog transaction — it is
-absent from the declaration plane, not filtered out of it. A tombstone file
-beside the moved directory carries `{id, host, identity, archivedAt, reason,
-archiveRoot}` and is published as one additive `archived` row in the
-`st2.catalog-graph.v2` envelope; an ordinary archived identity therefore leaves
-`complete: true` untouched, while an archived directory with no readable
-tombstone is unexplained control-plane state and makes the envelope incomplete.
-Eligibility is fail-closed and local-host only, because another host's runtime
-records are not observable: canonical path, retired in either spelling, no live
-or dead record for any declared task, and no remaining declaration referencing
-the subject's immutable ID as `supervisor`. `st2 catalog unarchive` is the exact
-reverse move; it preserves the archived ID, refuses an unmigrated archive after
-ID-aware activation, and validates ID uniqueness against the prospective
-live-and-archived subject set. A later transition to a routable desired state
-validates prospective effective-address uniqueness.
-
-The supervisor closes the same edge without an operator. Each `st2 up` reconcile
-pass ends by archiving every local seat whose retirement outlived the catalog's
-`archive-after` grace period (default `7d`; `"0"` disables the step), applying
-the same fail-closed eligibility as the verb and archiving at most 25 seats per
-pass so one pass stays bounded. The bound counts only seats that pass
-eligibility: a due seat the step refuses is reported and does not consume it,
-so refusals that recur every pass never starve the seats behind them. The step
-builds its batch incrementally: due seats are walked in identity order and
-each is judged against the seats already accepted this pass, which are the
-only ones counted as leaving. A supervisor whose retired dependent is not yet
-in the batch is refused as `supervisor-referenced` and leaves on a later pass,
-after the dependent, so the 25-seat cutoff never separates a supervisor from a
-dependent that still names it. The batch is re-checked against that rule
-before any move. The scan is bounded too: one pass examines at most 100 due
-seats (four times the archive bound), stops early once 25 are accepted, and
-reports the unexamined remainder as `auto-archive examined <n> due retired
-seats and deferred <m> to the next pass`. The next pass resumes the walk after
-the last seat examined, wrapping around, so a run of permanently refused seats
-cannot hold every pass's window. The step
-runs after the pass releases its shared lock and takes the exclusive lock
-non-blockingly: a contended lock skips the step, because a pass queued behind
-`st2 catalog apply` would stall every live agent's reconciliation and a due
-seat is still due next pass. st2 records no
-timestamp for a desired-state edit, so the grace period is measured from the
-supervisor's first observation of the retirement, kept in
-`.st2/retired-observed.json` (`st2.catalog-retired-observed.v1`) as host →
-identity → epoch millis and never in the spec. The same ledger keeps the
-resume point under `resumeAfter` (host → identity) only while the last pass
-left due seats unexamined. That ledger is reconciled to
-exactly the currently retired seats on every pass it runs, so a seat that comes
-back drops its row and a second retirement serves a fresh grace period; an
-absent or unreadable ledger restarts every clock and the scan, which errs
-toward keeping seats in the live catalog.
-
-The same supervisor step archives dead direct OMP actors (R48), because nothing
-else retires them: they have no declaration to retire. st2 owns this lifecycle
-([`0018-st2-owns-direct-actor-lifecycle`](.decisions/0018-st2-owns-direct-actor-lifecycle.md)).
-
-```mermaid
-stateDiagram-v2
-    [*] --> live: writer creates agents/<host>/direct.omp.<segment>
-    live --> deadObserved: no running record (row written)
-    deadObserved --> live: running record for ptyId (row dropped)
-    deadObserved --> archived: dead for archive-after (row dropped, rename + tombstone)
-    archived --> live: st2 catalog unarchive (fresh clock)
-```
-
-Liveness is exact PTY registry evidence. On the local host only, a direct
-actor is dead when the catalog's effective PTY registry — the one the pass
-already lists — holds no `running` record whose session ID equals its decoded
-`ptyId` byte for byte; an exited record, a vanished record, and an absent one
-are the same fact, and a running session whose ID merely contains the actor's
-does not keep it alive. Only the PTY backend counts: a running `exec` task
-whose runtime ID equals the `ptyId` is not the actor's session and does not
-keep it alive. Another host's registry is not observable, so its direct actors
-are never judged.
-
-Deaths are observed in `.st2/direct-dead-observed.json`, the same shape as the
-retirement ledger:
-
-```json
-{
-  "schema": "st2.catalog-direct-dead-observed.v1",
-  "hosts": { "dev3": { "direct.omp.2ahzpbs3": 1790000000000 } }
-}
-```
-
-Each value is the epoch millis of the supervisor's first observation of that
-death. Every pass that runs the step reconciles the local host's map to
-exactly the currently dead actors: a PTY that runs again drops its row, so a
-later death serves a fresh grace period. The ledger also keeps the direct scan's
-resume point under `resumeAfter` (host → identity) only while the last pass
-left due actors unexamined. An absent, unreadable, or foreign-schema ledger
-reads as empty and restarts every clock and the scan, which errs toward keeping
-actors live.
-
-The step obeys the same gates as retired-seat archival: `archive-after "0"`
-disables it, a contended exclusive lock skips it, and an incomplete strict
-discovery refuses it. The pass decides whether the step has work from its own
-discovery and the PTY backend's part of its registry snapshot; the step then
-re-reads the PTY registry alone under the exclusive lock, only when a local
-direct actor exists, and moves bytes only on that fresh read. Ordering within
-one pass:
-
-1. Eligible retired seats due under the retirement ledger fill the
-   25-per-pass bound first, within the 100-seat scan window above; due seats
-   the step refuses do not count, and a supervisor never takes a slot ahead of
-   a retired dependent that is not in the batch.
-2. Direct actors dead for at least `archive-after` fill what remains, in
-   identity order, starting after the ledger's resume point and wrapping
-   around. The scan is bounded like the retired-seat scan: it examines at most
-   four times the remaining bound (100 when no retired seat was accepted),
-   stops early once the remaining bound is filled, and reports the unexamined
-   remainder as `auto-archive examined <n> due dead direct actors and deferred
-   <m> to the next pass`; the next pass resumes after the last actor examined.
-3. A due actor whose `.st2/archive/<host>/<identity>` slot already exists is a
-   reported `archive-occupied` refusal. It does not consume the bound but does
-   consume the scan window, and keeps its ledger row, so it is retried whenever
-   the scan reaches it again until the slot is cleared.
-4. The rows of the selected actors are dropped in the same ledger write,
-   before the moves.
-5. Each selected actor is archived exactly like a retired seat, inside the same
-   generation commit: whole-directory rename to `.st2/archive/<host>/<identity>`
-   plus a tombstone whose `reason` is
-   `direct OMP actor: PTY session <ptyId> has no running record`.
-
-Dropping rows before the move means a failed move keeps the actor live for
-another full grace period, and `st2 catalog unarchive` restores the directory
-with no row, so the restored actor serves a fresh grace period instead of
-leaving again on the next pass. `st2 catalog archive` selects declarations only
-and refuses a direct actor as `unknown-identity`; the supervisor step is the
-only way a direct actor leaves. Nothing is deleted: the directory's bytes,
-`resources/tmp` included, move whole. How long an archived identity is
-retained is open ([DQ6](#open-design-questions)).
-
-Before starting a Codex provider, st2 asks that binary to generate its
-app-server JSON schemas and fingerprints only the delivery-critical projection:
-every client request and server notification arm st2 uses, the exact
-method-to-`params` reference for each arm, recursively referenced definitions,
-and response definitions st2 reads. Only reviewed fingerprints are admitted.
-Live turn, resume, and durable-receipt evidence remains a separate behavioral
-check and is not inferred from the fingerprint.

-## Message lifecycle
-
-```text
-sender intent → atomic inbox file → sender row → DING attempt → agent reads → archive receipt
-      │            └── pending/keyed retry reuses filename ──┘       │
-      └──────────── explicit partial coverage ───────────────────────┘
-```
-
-- **R05:** A matching archive filename makes an inbox copy handled; stale
-  duplicates are removed without another DING. Fresh `dnd` suppresses delivery;
-  `busy` does not. Failed delivery remains retryable. Sidecar restart emits a
-  bounded recovery notice instead of replaying the inbox. Delivery may wake an
-  agent while it is working, but an active or uncertain human composer must be
-  left untouched. Unsafe delivery retries use a bounded backoff so an active
-  composer cannot create a short-lived PTY probe on every inbox poll. Inbox
-  reads do not wake the sidecar; only mutations bypass its bounded poll cadence.
-- Sender-owned publication, crash recovery, coverage, and `message sent` are specified in
-  [`03-message/spec.md`](./03-message/spec.md). Recipient publication precedes a completed sender
-  row; the two directories do not share one atomic commit. Pending unkeyed intent resumes, but exact
-  replay after the intent clears requires a caller-supplied idempotency key.
-
-## State and scope
-
-- **R08:** Presence and activity status are separate signals. The version 1
-  presence record below defines presence freshness. The catalog must also
-  expose the agent's current plan and step with explicit freshness so a human
-  or supervising agent can understand progress without PTY inspection. The
-  canonical plan-progress shape is not yet specified.
-- **R09:** Durable work state is external to the model transcript and is
-  restored into replacement sessions through declared workspace files and
-  verified hooks.
-- **R10:** Fleet identities are agents. General-purpose identity kinds are
-  unsupported.
-
-### Presence record and freshness (R08)
-
-This section answers the presence part of DQ3. The version 1 implementation
-follows this contract.
-
-#### Version 1 record
-
-The presence record path is `<agent-dir>/status`.
-
-The status file uses this exact version 1 shape:
-
-```text
-available
-v1 1785802653486
-```
-
-Line one is one settable state: `offline`, `available`, `busy`, `away`, or
-`dnd`. `unknown` remains derived and is never written.
-
-Line two is `v1`, one ASCII space, and an unsigned base-10 timestamp. The
-timestamp counts milliseconds from the Unix epoch.
-
-The record ends with one newline. It has no other non-empty lines. Both lines
-form one atomic record.
-
-The state remains on line one for old readers. An old reader can ignore line
-two and continue to parse the state.
-
-#### Writers and atomicity
-
-`st2 status --set` writes the requested state with the current timestamp. A
-live session owner refreshes valid non-DND records every five minutes.
-
-A missing record becomes `available` with the current timestamp. The session
-owner does not refresh `dnd`, `unknown`, or malformed records.
-
-Every new writer emits version 1. It writes a temporary sibling and atomically
-renames the complete record over the target.
-
-A healthy periodic refresh changes the timestamp bytes. Replication can order
-that content change without using the source file mtime.
-
-#### Clock, freshness, and skew
-
-The timestamp uses the writer's UTC wall clock. A monotonic clock cannot cross
-a process restart or a host boundary.
-
-Participating hosts must keep their UTC clocks within sixty seconds. A larger
-clock error makes cross-host presence unknown.
-
-The stale interval remains fifteen minutes. A valid record is fresh while its
-age is less than fifteen minutes.
-
-A record becomes `unknown` when its age reaches fifteen minutes. This rule
-applies to every settable state, including `offline` and `dnd`.
-
-A timestamp up to sixty seconds in the reader's future is allowed. The reader
-uses zero age for this bounded future value.
-
-A timestamp more than sixty seconds in the future produces `unknown`. The
-reader does not use file mtime as a fallback for malformed version 1.
-
-Current readers treat a future legacy status mtime as fresh because they cannot
-calculate its age. A sufficiently future `dnd` mtime can therefore suppress
-delivery until the reader's clock catches up. The version 1 skew rules close
-this defect. They clamp only bounded future time and map larger future time to
-`unknown`.
-
-An unrecognized state still produces `offline`. A literal `unknown` produces
-`unknown`. A valid state with a malformed version, timestamp, or extra line
-also produces `unknown`.
-
-The sixty-second allowance is smaller than the five-minute refresh margin. It
-can extend a fresh DND hold by no more than sixty seconds.
-
-#### Why readers use origin time
-
-st2 does not require one catalog transport. Fabric is preferred, and Git over
-SSH or a plain copy remains supported.
-
-Git does not preserve file modification times. A checkout gives files the
-checkout time. Therefore, presence freshness lives in record bytes. No
-supported transport must preserve file metadata.
-
-Replica arrival time measures transport delay, not agent activity. The
-embedded writer time protects presence freshness, DND expiry, and the status
-contribution to `lastActivity`.
-
-The same reason applies to the context boot freshness check. A replica arrival
-must not make old context appear fresh. This proposal does not change the
-context record.
-
-#### DND behavior
-
-A fresh `dnd` record suppresses DING delivery. The session owner leaves its
-timestamp unchanged, so an abandoned hold ages out.
-
-A stale or invalid DND record does not suppress delivery. It reads as
-`unknown`, which preserves the existing fresh-DND rule.
-
-Replication delay cannot renew a DND hold. The reader uses the embedded write
-time, not the replica materialization time.
-
-#### Legacy rollout
-
-A legacy record contains one valid state line and no version line. The first
-version 1 reader release uses legacy file mtime for freshness.
-
-Version 1 writers never emit a legacy record. A live non-DND session owner
-upgrades its legacy record at its next five-minute refresh.
-
-A version 1 session owner upgrades a legacy DND record once. It uses the legacy
-mtime as the embedded timestamp, so the migration cannot renew the hold.
-
-After that migration, the session owner does not refresh DND. If the legacy
-mtime is unavailable, the session owner leaves the record unchanged.
-
-A malformed two-line record is not legacy. Readers must not hide a bad version
-1 record behind the legacy mtime fallback.
-
-Fallback removal is a separate reviewed change. Removal requires all three
-receipts below:
-
-1. Every supported deployed status writer emits version 1.
-2. Two fleet scans, separated by fifteen minutes, find no active legacy record.
-3. No supported or retained rollback binary can emit a legacy record.
-
-After removal, a one-line record produces `unknown`. No presence freshness
-decision then depends on status file mtime.
-
-#### `lastActivity`
-
-For a version 1 status record, `lastActivity` uses the embedded timestamp. It
-does not use the replica materialization mtime.
-
-The reader clamps an allowed future timestamp to its current time. It omits a
-malformed version 1 timestamp from the activity calculation.
-
-Inbox and archive entries continue to use their local file mtimes. During the
-legacy window, a one-line status record also contributes its file mtime.
-
-This choice reports when the agent wrote its heartbeat. A delayed replica
-cannot make an old heartbeat appear to be new agent activity.
-
-## Provider session-start restoration (R07, R09, R17, R33)
-
-```text
-fresh durable context --\
-                         +--> compose text --> jq -Rs stdin --> provider JSON stdout
-boot ritual ------------/                         |
-                                                  `--> construction failure signal
-```
-
-The Claude SessionStart hook reads fresh context through `st2 context read`,
-wraps non-whitespace content in a source-and-agent envelope, appends the boot
-ritual, and streams the complete composed text into `jq`. `jq` raw-slurps stdin
-and emits `continue: true` plus
-`hookSpecificOutput { hookEventName: "SessionStart", additionalContext }` on
-stdout. Context bytes never occupy one process argument and are not truncated.
-
-Missing or stale context omits the envelope while retaining the ritual. A
-missing `jq` fails open with exit 0 and no output; a missing `st2` fails open
-with the ritual only. These are supported degraded starts, not evidence that
-context was delivered. Any other JSON-construction or delivery failure must be
-distinguishable from those cases and propagate durably under R17.
-
-Executable acceptance in `tests/claude_hooks.rs` covers the model-visible
-stdout envelope, empty stderr, missing and stale context, missing dependencies,
-and context larger than a platform argument limit without truncation. That
-target is gated: it is in `checks.st2`'s `cargoTestFlags` and the derivation
-supplies its `bash` and `jq`, so a regression fails CI. Durable failure
-propagation under R17 is a separate axis and stays open as DQ5.
-
-The owner updates this spec whenever implementation changes.
-Changing [vision.md](./vision.md) or [requirements.md](./requirements.md)
-requires Alex's explicit approval.
-
-## pi native delivery
-
-pi has no MCP, no app-server, and no lifecycle-hook mechanism. Its integration
-point is an extension loaded into the live interactive process. st2 therefore
-delivers to pi through a channel that runs inside the session rather than
-through the terminal.
-
-```text
-inbox --> st2 driver pi-channel --NDJSON--> pi-channel.ts --> pi.sendUserMessage()
-                   ^                              |
-                   `-------- delivered/failed ----'
-```
-
-`st2 driver pi-session` owns the launch. It resolves `pi-channel.ts` from this
-binary's verified immutable hook set and splices `-e <path>` in immediately
-after the provider program, so a declaration never carries a machine-local
-path. It exports `ST2_PI_CHANNEL_BIN`, `ST2_PI_CHANNEL_CATALOG`, and
-`ST2_PI_CHANNEL_IDENTITY`; the extension spawns exactly that binary rather than
-resolving `st2` from `PATH`, which is what keeps a replaced control plane and
-its live agents from disagreeing under R11. The wrapper also owns the
-five-minute presence heartbeat for as long as its provider lives, on the same
-terms as the Claude wrapper.
-
-The channel is newline-delimited JSON in both directions. It opens with
-`{"type":"hello","protocol":1,"identity":...}`; an extension that does not
-understand the protocol number closes the channel rather than guessing. Each
-unread inbox entry becomes one `{"type":"message","deliverAs":...,"content":
-...,"meta":{...}}` frame carrying the same subject-and-body envelope the Claude
-channel uses. The inbox remains the durable source of truth: the channel holds
-only an ephemeral set of filenames delivered in its current lifetime, and a
-restart rescans. EOF on stdin is the session boundary.
-
-pi has no session-start hook, so the `hello` frame also carries
-`sessionContext`: the same restored working state, boot ritual, and
-unread-inbox listing that `$ST_HOOKS/codex-session-start.sh` composes, in the
-same order, composed here in Rust. The extension awaits that frame inside
-`session_start`, which orders restoration ahead of the boot turn rather than
-after it, and a fresh channel is opened for `/new`, `/resume`, and `/fork`, so
-a replaced session is restored on the same terms.
-
-`deliverAs` is st2's decision, not the extension's, so delivery behaviour is a
-Rust change with one place to make it. The shipped value is `steer`: the
-earliest point pi accepts input without discarding the running turn, and the
-same choice the Codex native path makes when it routes an active turn to a
-steer. Measured against a live provider, the boundary is one tool call, not one
-job — each tool call and its result are their own assistant message, so a steer
-sent mid-job is injected in the same millisecond as the next tool result.
-Latency is bounded by the in-flight call's remaining duration. Whether displaced
-work resumes is the model's choice, not a harness guarantee. Holding until the agent settles would defer
-delivery inside pi where st2 cannot observe it, which is what the "`busy`
-delivers immediately" rule exists to prevent. Per-message selection between
-steer and queue is tracked in #277.
-
-A managed pi seat runs with `PI_OFFLINE=1` and `PI_SKIP_VERSION_CHECK=1` unless
-its declaration already sets them: a supervised agent must not self-update or
-make its boot latency depend on the network. The extension unexports
-`ST2_PI_CHANNEL_*` once it has read it, because pi places its environment in
-front of every tool child, and eval seats scrub `PI_*` for the same reason they
-scrub `CLAUDE_*` and `CODEX_*`.
-
-st2 pins no pi version. pi publishes none to pin — no changelog, stability
-policy, compat field, or API version constant — but it does publish its
-TypeScript declarations, and those govern this coupling.
-`checks.pi-extension-types` type-checks the shipped extension against a pinned
-pi release at build time, which is what makes the asset's otherwise-erased
-`import type` load-bearing. This follows the repo's existing rule that st2 validates
-where skew fails silently (`pty`, the Codex app-server schema) and not where it fails
-loudly (`claude`); the extension's one silent surface was its idle proof, and using
-that proof without calling it is now a build error.
-
-A pi agent never enters the DING path. `deliver` and `ding` are mutually
-exclusive in a declaration, so no PTY write is authorized for a pi seat and the
-synchronous composer proof is not consulted. Workspace trust is a launch flag
-(`pi -a`), so nothing in the operator's ambient pi configuration is mutated and
-there is no pi analogue of the pre-boot trust batching Claude requires.
-
-The measured basis for this design, including the runs that fixed `steer` and
-the modal case, is recorded in
-[2026-08-18-pi-harness-integration](./.experiments/2026-08-18-pi-harness-integration.md);
-the ruling is
-[`0005-pi-delivers-natively-through-an-injected-extension`](./.decisions/0005-pi-delivers-natively-through-an-injected-extension.md).
-
-## Event contracts (R13–R15, R40)
-
-An event is evidence, not permission to mutate runtime state. The classifier
-maps each accepted path and kind to one consumer. A resident catalog wake
-starts one serialized full-catalog pass; discovery and runtime observation then
-compute the desired-versus-actual delta, and an empty plan performs no launch,
-teardown, materialization, or catalog write.
-
-Watchers are deny-by-default. The classifier/action contract is:
-
-| Event | Minimal action |
-| --- | --- |
-| `.st2/catalog-generation` create/modify/replace | queue one serialized full-catalog reconcile after a cooperative commit |
-| root `catalog.kdl` create/modify/remove | queue one serialized full-catalog reconcile |
-| declaration-space `**/agent.kdl` create/modify/remove or declaration-directory topology change | queue one serialized full-catalog reconcile |
-| referenced `_templates/**` mutation | queue one serialized full-catalog reconcile |
-| inbox create/archive/remove | DING consumer only; supervisor no-op |
-| plan/resource/status mutation | specialized consumer only; supervisor no-op |
-| PTY/exec/log/PID/socket/lock/temp/backup/read/open/unknown | no-op |
-
-The catalog-generation watcher owns a separate backend instance and one
-non-recursive control-directory subscription. It revalidates that directory's
-identity after every pass and reinstalls a stale subscription. The declaration
-watcher owns shallow subscriptions only for declaration-space directories; it
-prunes `.git`, `.st2`, PTY state, inboxes, archives, and Resource payloads. Both
-channels forward unit wakes to the same single-threaded loop. A burst is drained
-before one pass, and a pass never overlaps another pass.
-
-Watcher setup or callback failure is diagnosed and queues a conservative audit
-when a callback exists. The independent channel remains live. Startup, timer,
-watcher overflow/loss, and ambiguity are bounded full-audit fallbacks.
-Executable proof covers a post-commit generation replacement, generation-watch
-reinstallation after control-directory replacement, direct atomic bundle
-publication at production catalog scale, root configuration and declaration
-wakes, negative runtime/bus events, disconnected-channel cadence, and an idle
-supervisor that does not wake on its own reads.
-
-## Quiet coordination after events (R22)
-
-Useful work is quiet by default. Presence, status, and durable plan data are
-facts. They do not cause a status message or a peer poll.
-
-Coordination starts only after one of these events:
-
-- An unread inbox message. DING the recipient. Process or hand off the request.
-- A durable failure or real blocker. Tell the responsible supervisor. Find the cause.
-  Repair the failure or escalate it.
-- A completion or decision. Give the result to the agent or principal that needs it.
-- A declared schedule with a name. Do that work. Do not replace the schedule
-  with repeated messages or polls.
-
-After an event, continue until you resolve the need or hand it off. Then become quiet.
-
-The inbox uses the source contract in
-[DING requirements](./01-ding/requirements.md). A normal supervisor handles
-failures and blocked work. It does not continuously manage healthy agents. A
-custom supervisor persona can ask for more frequent coordination. CoS is only
-an example. st2 does not require or define that role, and R22 gives it no
-standard authority.
-
-R22 does not define the schedule grammar in DQ1. A schedule must have a declared
-name. Transport loss can delay coordination. It does not stop independent
-host-local work. Local work does not depend on a global service.
-
-## Targeted reconciliation (R19)
-
-`st2 up --materialize-only --task <host.agent.task>` resolves one exact local
-task before writing and renders only its owning agent. `st2 up --once --task
-<host.agent.task>` performs the same owner-only materialization, then inspects
-PTY/exec state and executes a plan containing only that task. Unknown,
-ambiguous, and wrong-host selectors refuse before writes or runner inspection;
-unrelated discovery diagnostics remain visible without preventing the selected
-owner/task path. A live generated companion may be adopted or retired as that
-exact selected task. An active dead or absent generated companion is held: the
-bounded pass cannot start its canonical agent without broadening the selector.
-Explicitly authored sibling tasks retain ordinary selected-task behavior.
-
-`st2 up --materialize-only --agent <id>` remains the agent-wide rendering
-selector. Targeted task reconciliation is intentionally bounded to `--once`;
-the resident supervisor continues to reconcile the complete local catalog.
-
-## Open design questions
-
-- **DQ1 Scheduled work:** The vision includes per-machine schedulers that form a
-  distributed workflow engine, but the KDL shape, event inbox, deduplication
-  boundary, and execution receipts are not yet specified. A successful
-  executable eval and Alex's approval should resolve this before adding
-  scheduler requirements. Three of the four unspecified items now have accepted
-  answers in the [stream subsystem](04-stream/requirements.md): the event inbox
-  is the ordinary agent inbox, deduplication is `(stream, event-id)` per
-  recipient, and receipts are the `created | deduplicated` emit receipt plus
-  archive filenames. The `schedule` KDL shape, its relationship to a timer
-  stream, and the approval above remain open; `every` on a stream stays
-  rejected so this question is not resolved by implication.
-- **DQ2 Safe DING delivery:** Bounded observation now replaces the fixed
-  paste-to-Return delay: maintained Codex and Claude composers must be
-  positively empty before paste and show the exact staged notice twice before
-  a separate Return. Human, modal, active, changed, timed-out, and unknown
-  states fail closed, with staged-payload ownership preventing duplicate paste.
-  This measured screen heuristic is still not an evented proof and renderer
-  changes may defer delivery. Resolve the remaining gap with a stronger evented
-  signal or other measured classifier; a small on-device model is an optional
-  experiment, not a required architecture. The
-  [05-harness-state](05-harness-state/spec.md) pi producer is the first
-  evented signal for any harness (the injected extension's positive idle
-  observation); it informs observability only — delivery keeps its own
-  evidence, and no DING path reads the observed-state record.
-- **DQ3 Remaining catalog agent state:** The R08 presence record above
-  defines the presence path, schema, freshness, and atomic update rules.
-  The *observed* axis is now specified in
-  [05-harness-state](05-harness-state/requirements.md) (decision 0006): a
-  driver-written record with its own staleness rules, distinct from declared
-  presence and from R08's declared activity status. *Declared* activity
-  status, current plan, and current plan step remain undefined. The
-  stale-state gate is addressed for the observed axis; the
-  supervisor-following gate is not
-  ([DQ-H5](05-harness-state/open-questions.md)) — prove both before adding
-  any of these shapes to `AGENT-SPEC.md`.
-- **DQ4 Relaunch boundary (R29-R30):** Preserve R11's nondisruptive adoption
-  while making launch drift visible. For each declared task, derive the desired
-  launch fingerprint from a deterministic, versioned encoding of only:
-  backend kind, lowered shell source or direct argv, resolved working directory,
-  and the st2-managed plus declared effective environment. Tags, descriptive
-  metadata, unrelated inherited environment, file contents, and other boot-time
-  snapshots are not part of this fingerprint.
-
-  As part of its own successful task launch, st2 records the observed
-  fingerprint together with that launch's exact runtime identity and creation
-  incarnation. The observed fingerprint is trustworthy only while the current
-  live runtime exactly matches that binding. Inspection then reports:
-
-  | State | Meaning | Healthy-task action |
-  | --- | --- | --- |
-  | `converged` | desired and bound observed fingerprints match | adopt |
-  | `drifted` | desired and bound observed fingerprints differ | adopt and report drift |
-  | `unknown` | the observed binding is missing or does not match the live runtime | adopt and report unknown |
-
-  `unknown` includes a healthy legacy or externally adopted runtime, as well as
-  a manual PTY restart or external child replacement whose runtime identity or
-  creation incarnation no longer matches st2's launch record. Stale observed
-  metadata is never reused for the new incarnation. Catalog publication,
-  supervisor restart, metadata edits, and launch-field edits do not implicitly
-  disrupt any healthy task.
-
-  Ordinary reconciliation remains sufficient after every interruption:
-
-  | Declaration | Process | Action |
-  | --- | --- | --- |
-  | active | absent or dead | reap stale state and launch the latest current desired contract |
-  | active | alive | adopt and report `converged`, `drifted`, or `unknown` |
-  | retired | alive | stop; do not relaunch |
-  | retired | absent or dead | do not launch |
-
-  Replacing live drifted work is a separate explicit operation. Its scope is
-  one selected catalog, pinned host, resolved effective PTY root, and selected
-  task set. A future interface may preview drifted tasks and select one, a
-  subset, or all of them; this contract does not reserve a command name. The
-  operation must re-read the selected task and recheck its exact live runtime
-  identity immediately before each stop. A missing, changed, wrong-host, or
-  wrong-root target refuses without disruption.
-
-  Replacement does not capture an old launch contract or boot inputs. If st2
-  stops after the identity check and is then interrupted, ordinary
-  absent/dead reconciliation launches the latest current desired contract.
-  There is no replay of an older generation, durable operation journal,
-  operation ID, phase machine, terminal receipt, or atomic old-to-new runtime
-  transition. A task rename is the explicit sequence retire old, then add new.
-
-  This entire lifecycle works from an ordinary copied or synchronized catalog
-  folder. CAS may later add publication, history, or storage optimization, but
-  fingerprinting, inspection, reconciliation, replacement, retirement,
-  recovery, and rename must neither require nor become incomplete without it.
-
-  Executable acceptance proves:
-
-  1. metadata, tags, and Resource-only edits preserve the fingerprint and live
-     runtime, while kind, launch, resolved-cwd, or effective-environment edits
-     report `drifted` without changing runtime identity;
-  2. a healthy legacy runtime reports `unknown` and remains unchanged, and a
-     manual or external restart with a changed runtime identity or creation
-     incarnation cannot reuse the prior observed fingerprint and reports
-     `unknown`;
-  3. natural exit or death launches once from the latest current declaration
-     and records that launch's observed fingerprint;
-  4. explicit replacement refuses stale identity or scope, and affects only
-     the selected drifted tasks;
-  5. interruption after stop heals through ordinary reconciliation to the
-     latest current desired contract, without old-state replay;
-  6. retirement stops and prevents relaunch, while rename works as
-     retire-old/add-new; and
-  7. the same proofs pass using only a plain local catalog folder with no CAS
-     service, CAS metadata, database, or network dependency.
-
-  The executable acceptance above resolves this open implementation design.
-  See [#40](https://github.com/compoundingtech/st2/issues/40),
-  [#41](https://github.com/compoundingtech/st2/issues/41),
-  [#44](https://github.com/compoundingtech/st2/issues/44), and
-  [#60](https://github.com/compoundingtech/st2/issues/60).
-- **DQ5 Session-start failure receipt (R17, R33):** The hook has explicit
-  fail-open results for missing enrichment dependencies, but an unexpected
-  `jq` construction failure can still leave the provider without context or a
-  durable supervisor-visible receipt. Resolve the gap by defining and proving
-  a failure signal that does not block provider startup, is distinguishable
-  from an ordinary cold start, and reaches the responsible supervisor under
-  R17.
-- **DQ6 Archive retention (R48):** Archival moves whole identity
-  directories, `resources/tmp` included, and nothing ever prunes
-  `.st2/archive`, so the archive grows without bound and can dominate a
-  long-lived catalog's tree. Any retention rule is irreversible, unlike
-  archival itself. Resolve by choosing what an archived identity keeps
-  (declaration, decisions, notes, tombstone) versus what may be dropped or
-  packed, naming the owner of that deletion, and deciding whether the
-  per-seat `resources/tmp` budget is enforced before archival. See
-  [#530](https://github.com/compoundingtech/st2/issues/530).

-## The Problem
-
-1. **Agent specs need an executable eval runtime.** A spec cannot be proven
-   through prose; evals need a runner that executes it reproducibly.
-2. **Proven agent specs need a real-work runtime.** The same declarations must
-   run day-to-day agent work, or eval evidence and production behavior will
-   drift apart.
-3. **That runtime must be reliable in operation.** Launch configuration, hooks,
-   messages, and durable state can drift or disappear across restarts and
-   machines. Without externalized state, humans and supervisors must inspect
-   terminals to learn whether an agent is present or making progress, while
-   failures still need intelligent diagnosis and recovery.
-
-## The Vision
-
-- A reliable, declared runtime for agent specs.
-- Per-machine schedulers that together form a distributed workflow engine for
-  agent work.
-- One intelligent root agent on each machine to supervise local runtime health,
-  recovery, and escalation.
-- Catalog-visible agent presence, activity status, and current plan progress.
-- Durable message passing and encapsulated agent state.
-- A concrete implementation of the executable agent spec maintained by
-  `compoundingtech/evals`.
-
-## What This Is Not
-
-- A general messaging or identity platform for people, services, or arbitrary
-  non-agent actors while the agent and st2 specs are still stabilizing.
-
-## Success Criteria
-
-1. Every supported agent-spec capability has an implemented and validated st2
-   path, with unsupported behavior stated plainly.
-2. A canonical agent declaration can be validated, materialized, launched, and
-   restarted without losing its effective launch definition or durable state.
-   The st2 control plane itself can be stopped, killed, reinstalled, and
-   restarted without stopping or replacing any running agent; the replacement
-   runtime adopts the existing agent processes without duplication.
-3. Each supervisor tree has one root agent that observes its runtime health,
-   resolves bounded failures, and escalates what it cannot resolve.
-4. A human, CoS, root, or supervisor can inspect catalog-backed state to
-   determine an agent's presence, activity status, current plan, and current
-   plan step without opening its PTY or relying on its transcript; stale state
-   is explicit.
-5. Host placement, hooks, message delivery, archive handling, and recovery have
-   explicit contracts and executable evidence.
-6. Agent work can be scheduled or triggered as durable, inspectable workflows
-   across the declared fleet.
-7. Agent messages arrive reliably without corrupting, combining with, or
-   submitting a human's active input.

 # Local eval corpus
 
-This repository keeps an st2 and an st3 form of each migration eval.
+The [Fractal corpus](fractal/) contains the current eval fixtures. Each KDL-backed eval
+starts with `version 2`; complete harness variants can live in its `variants/` directory.
+Future imports require an explicit eval review before they enter this corpus.
 
-An st3-only eval can prove a new runtime feature that st2 does not implement.
+## Eval and harness inventory
 
-The initial st2 corpus came from `compoundingtech/evals` commit `3db48ab56d40ce27dfd94f89d2db9b692d93836a`.
+The model-free and model-backed lists in
+[`crates/fractal/tests/examples.rs`](../crates/fractal/tests/examples.rs) are the maintained
+inventory. Its tests compare those lists with the actual `evals/fractal/*/eval.kdl` files,
+check that model-free fixtures have no model seats or gates, and verify the declared native
+harnesses and model judges. Read the current fixture and controller for exact models and
+seat counts rather than using a second hand-copied aggregate here.
 
-Future imports require an explicit eval review before they enter this corpus.
+To list KDL files from the repository root:
+
+```sh
+rg --files evals/fractal -g eval.kdl
+```
+
+The inventory includes attention inbox, free mode, loop exhaustion/feedback/until-green,
+queue revision, replication convergence, review escalation, runtime readiness recovery and
+seat mission work. [Codex minimal access](fractal/codex-minimal-access/eval.kdl) declares one
+Codex worker and no model judge; its gates check managed minimal permissions.
 
+A runner may create its agents dynamically. Graceful messaging uses
+`scripts/fractal-graceful-messaging-eval/run` and records the selected harnesses in its report;
+it has no eval KDL. Messaging faults uses real native drivers and embedded extensions with a
+token-free provider stand-in across two isolated nodes, so it adds no native model seats.

-The paired and st3-only corpus has 14 Claude seats, 43 Codex seats, two Pi seats, two OMP seats,

-
-Graceful messaging is not in those seat counts: `scripts/fractal-graceful-messaging-eval/run` chooses
-its seats at run time, and its committed reports name them. It needs no eval KDL, because it restarts
-and replaces its own daemon.
-
-Seat queue is counted with its default Claude seat. `scripts/fractal-seat-queue-eval/run` can put Codex
-`gpt-6-luna` or omp `openai-codex/gpt-5.6-luna` in that seat instead. Its chief agent is a
-model-free command, not a native agent seat.
-
-The twenty-three model-free Fractal evals add no model seats and no LLM judges.
-Messaging faults runs real native drivers and embedded extensions with a token-free provider API
-stand-in across two isolated nodes; it adds no native model seats.
-
-Claude task baselines remain explicitly pinned to `claude-sonnet-5`; the native-channel wake
-canary uses Claude Code's `opus` alias and records the concrete model selected by the provider.
-
-Model agents must use a native `harness` block. A setup or fixture process can use `command`.
-
-An eval can keep seat variants in `variants/`. A variant is a complete eval KDL that changes only the
-seat under test, so one fixture can compare harnesses. The omp readiness runs use omp on
-`openai-codex/gpt-5.6-luna`, Codex `gpt-6-luna`, and Claude `claude-sonnet-5` variants of
-cross-harness message wake, work wake reliability, seat mission work, and restart continuity.
-Cross-harness message wake also has omp `openai-codex/gpt-5.6-sol` and `openai-codex/gpt-6-astra`
-variants for the omp model comparison.
-
-Codex `gpt-5.6-sol` is the default model judge.
-
-An eval can use a Claude judge for a specific reason. Record the choice in this inventory and the run report.
+Model agents use a native `harness` block. Setup and fixture processes can use `command`.
+A variant is a complete eval KDL that changes only the seat under test. Keep native agents
+and model judges distinct in the run report, and record the concrete provider model when
+a fixture selects an alias. Fixture declarations pin their own task models and judges.

-# Claude Skill Inheritance eval for st2
-
-This eval tests the union of project and plugin skills in one native Claude Sonnet seat.
-
-The task does not contain either secret token. Each loaded skill writes its own token to a sentinel file.
-
-The plugin uses a session-only relative `--plugin-dir`. The isolation judge checks the personal Claude scope.

-# fd.a — eval PROPOSER (fork-in-the-road / design panel)
-
-You are `fd.a`, one of three proposers on a design panel. You own **your current directory only**;
-your deliverable is `PROPOSAL.md` **committed in this dir**.
-
-## Hard rules — this is exactly what is being tested
-- The supervisor (`fd.sup`) will assign you a **genuinely distinct** approach to champion over the bus
-  (you'll be woken by a ding). The shared design brief is in `PROBLEM.md` (already here).
-- Write a **strong, honest** `PROPOSAL.md` in **your own dir**: steelman your assigned approach AND own
-  its real weaknesses / what it trades away. Consider cross-human **privacy / information-isolation** as a
-  first-class tradeoff where relevant.
-- **Debate** the tradeoffs with the other proposers over the bus — engage their points, update where
-  warranted, state crisply where a real fork remains. Real disagreement, not instant consensus.
-- **Commit** `PROPOSAL.md` in your dir. **Never write or commit in another agent's dir.**
-- Coordinate only over the bus. Stay in your own dir/lane.
-
-## Boot ritual (do this first, every fresh start)
-1. Set your status available: `st2 status "$ST_AGENT" --set available`.
-2. Drain your inbox: `st2 message ls`, read each, reply if warranted, archive it.
-3. Then act — await `fd.sup`'s assignment, then propose + debate.
-
-Your correspondent is your interlocutor: everything goes over the bus with `st2 message`, never to your screen.

-# Design problem — sharing one agent team across MULTIPLE humans
-
-Today this agent team effectively serves one human (the operator). We are about to let a **small group of
-humans** share it. Design **how humans relate to the agent team when there is more than one of them.**
-
-This is an **open design problem** — there is no single right answer, only tradeoffs. People have
-floated a few shapes as a *starting hint* (not the answer set — decide the real set yourselves):
-
-- **one chief-of-staff (CoS) per human** — each human has their own CoS; the CoSs coordinate.
-- **one shared CoS** — a single CoS serves everyone.
-- **a federated CoS-mesh** — a hybrid: per-human CoS + a shared coordination layer / specialist pool.
-
-## What a good answer contains
-- Several **genuinely distinct** approaches (not three flavors of one), each argued at its **strongest**
-  and **honest** about where it is weak / what it trades away.
-- A real **debate of the tradeoffs** — engage each other's points, update where warranted, and state
-  crisply where a real fork remains.
-- A **justified recommendation** (or "prototype X first, because Y") that follows from the analysis.
-- Explicitly separate **what the team can decide** (the technical shape) from **what it should NOT
-  decide for the humans** — escalate the values/irreversible calls back to them.
-
-Deliverable: each proposer writes `PROPOSAL.md` in their own dir; the supervisor synthesizes
-`RECOMMENDATION.md` in its own dir. Coordinate everything through the st2 bus. Stay in your own dir.

-
-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
-   merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
-   it is deleted.  If you need to build on top of it to correct
-   earlier mistakes, a new topic branch is created by forking at
-   the tip of the "master".  This is not strictly necessary, but
-   it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
-   branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next".  Young
-    topic branches can have stupid mistakes you would rather
-    clean up before publishing, and things that have not been
-    merged into other branches can be easily rebased without
-    affecting other people.  But once it is published, you would
-    not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
-    Then you can delete it.  More importantly, you should not
-    build on top of it -- other people may already want to
-    change things related to the topic as patches against your
-    "master", so if you need further changes, it is better to
-    fork the topic (perhaps with the same name) afresh from the
-    tip of "master".
-
-Let's look at this example:
-
-		   o---o---o---o---o---o---o---o---o---o "next"
-		  /       /           /           /
-		 /   a---a---b A     /           /
-		/   /               /           /
-	       /   /   c---c---c---c B         /
-	      /   /   /             \         /
-	     /   /   /   b---b C     \       /
-	    /   /   /   /             \     /
-    ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished.  It has been fully merged up to "master" and "next",
-   and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
-	git rev-list ^master ^topic next
-	git rev-list ^master        next
-
-	if these match, topic has not merged in next at all.
-
-To compute (2):
-
-	git rev-list master..topic
-
-	if this is empty, it is fully merged to "master".

-# An example hook script to update a checked-out tree on a git push.
-#
-# This hook is invoked by git-receive-pack(1) when it reacts to git
-# push and updates reference(s) in its repository, and when the push
-# tries to update the branch that is currently checked out and the
-# receive.denyCurrentBranch configuration variable is set to
-# updateInstead.
-#
-# By default, such a push is refused if the working tree and the index
-# of the remote repository has any difference from the currently
-# checked out commit; when both the working tree and the index match
-# the current commit, they are updated to match the newly pushed tip
-# of the branch. This hook is to be used to override the default
-# behaviour; however the code below reimplements the default behaviour
-# as a starting point for convenient modification.
-#
-# The hook receives the commit with which the tip of the current
-# branch is going to be updated:
-commit=$1
-
-# It can exit with a non-zero status to refuse the push (when it does
-# so, it must not modify the index or the working tree).
-die () {
-	echo >&2 "$*"

-
-# Or it can make any necessary changes to the working tree and to the
-# index to bring them to the desired state when the tip of the current
-# branch is updated to the new commit, and exit with a zero status.
-#
-# For example, the hook can simply run git read-tree -u -m HEAD "$1"
-# in order to emulate git fetch that is run in the reverse direction
-# with git push, as the two-tree form of git read-tree -u -m is
-# essentially the same as git switch or git checkout that switches
-# branches while keeping the local changes in the working tree that do
-# not interfere with the difference between the branches.
-
-# The below is a more-or-less exact translation to shell of the C code
-# for the default behaviour for git's push-to-checkout hook defined in
-# the push_to_deploy() function in builtin/receive-pack.c.
-#
-# Note that the hook will be executed from the repository directory,

-# fd.b — eval PROPOSER (fork-in-the-road / design panel)
-
-You are `fd.b`, one of three proposers on a design panel. You own **your current directory only**;
-your deliverable is `PROPOSAL.md` **committed in this dir**.
-
-## Hard rules — this is exactly what is being tested
-- The supervisor (`fd.sup`) will assign you a **genuinely distinct** approach to champion over the bus
-  (you'll be woken by a ding). The shared design brief is in `PROBLEM.md` (already here).
-- Write a **strong, honest** `PROPOSAL.md` in **your own dir**: steelman your assigned approach AND own
-  its real weaknesses / what it trades away. Consider cross-human **privacy / information-isolation** as a
-  first-class tradeoff where relevant.
-- **Debate** the tradeoffs with the other proposers over the bus — engage their points, update where
-  warranted, state crisply where a real fork remains. Real disagreement, not instant consensus.
-- **Commit** `PROPOSAL.md` in your dir. **Never write or commit in another agent's dir.**
-- Coordinate only over the bus. Stay in your own dir/lane.
-
-## Boot ritual (do this first, every fresh start)
-1. Set your status available: `st2 status "$ST_AGENT" --set available`.
-2. Drain your inbox: `st2 message ls`, read each, reply if warranted, archive it.
-3. Then act — await `fd.sup`'s assignment, then propose + debate.
-
-Your correspondent is your interlocutor: everything goes over the bus with `st2 message`, never to your screen.

-# Design problem — sharing one agent team across MULTIPLE humans
-
-Today this agent team effectively serves one human (the operator). We are about to let a **small group of
-humans** share it. Design **how humans relate to the agent team when there is more than one of them.**
-
-This is an **open design problem** — there is no single right answer, only tradeoffs. People have
-floated a few shapes as a *starting hint* (not the answer set — decide the real set yourselves):
-
-- **one chief-of-staff (CoS) per human** — each human has their own CoS; the CoSs coordinate.
-- **one shared CoS** — a single CoS serves everyone.
-- **a federated CoS-mesh** — a hybrid: per-human CoS + a shared coordination layer / specialist pool.
-
-## What a good answer contains
-- Several **genuinely distinct** approaches (not three flavors of one), each argued at its **strongest**
-  and **honest** about where it is weak / what it trades away.
-- A real **debate of the tradeoffs** — engage each other's points, update where warranted, and state
-  crisply where a real fork remains.
-- A **justified recommendation** (or "prototype X first, because Y") that follows from the analysis.
-- Explicitly separate **what the team can decide** (the technical shape) from **what it should NOT
-  decide for the humans** — escalate the values/irreversible calls back to them.
-
-Deliverable: each proposer writes `PROPOSAL.md` in their own dir; the supervisor synthesizes
-`RECOMMENDATION.md` in its own dir. Coordinate everything through the st2 bus. Stay in your own dir.

-
-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
-   merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
-   it is deleted.  If you need to build on top of it to correct
-   earlier mistakes, a new topic branch is created by forking at
-   the tip of the "master".  This is not strictly necessary, but
-   it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
-   branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next".  Young
-    topic branches can have stupid mistakes you would rather
-    clean up before publishing, and things that have not been
-    merged into other branches can be easily rebased without
-    affecting other people.  But once it is published, you would
-    not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
-    Then you can delete it.  More importantly, you should not
-    build on top of it -- other people may already want to
-    change things related to the topic as patches against your
-    "master", so if you need further changes, it is better to
-    fork the topic (perhaps with the same name) afresh from the
-    tip of "master".
-
-Let's look at this example:
-
-		   o---o---o---o---o---o---o---o---o---o "next"
-		  /       /           /           /
-		 /   a---a---b A     /           /
-		/   /               /           /
-	       /   /   c---c---c---c B         /
-	      /   /   /             \         /
-	     /   /   /   b---b C     \       /
-	    /   /   /   /             \     /
-    ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished.  It has been fully merged up to "master" and "next",
-   and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
-	git rev-list ^master ^topic next
-	git rev-list ^master        next
-
-	if these match, topic has not merged in next at all.
-
-To compute (2):
-
-	git rev-list master..topic
-
-	if this is empty, it is fully merged to "master".

-# tries to update the branch that is currently checked out and the
-# receive.denyCurrentBranch configuration variable is set to

-# as a starting point for convenient modification.

-# fd.c — eval PROPOSER (fork-in-the-road / design panel)
-
-You are `fd.c`, one of three proposers on a design panel. You own **your current directory only**;
-your deliverable is `PROPOSAL.md` **committed in this dir**.
-
-## Hard rules — this is exactly what is being tested
-- The supervisor (`fd.sup`) will assign you a **genuinely distinct** approach to champion over the bus
-  (you'll be woken by a ding). The shared design brief is in `PROBLEM.md` (already here).
-- Write a **strong, honest** `PROPOSAL.md` in **your own dir**: steelman your assigned approach AND own
-  its real weaknesses / what it trades away. Consider cross-human **privacy / information-isolation** as a
-  first-class tradeoff where relevant.
-- **Debate** the tradeoffs with the other proposers over the bus — engage their points, update where
-  warranted, state crisply where a real fork remains. Real disagreement, not instant consensus.
-- **Commit** `PROPOSAL.md` in your dir. **Never write or commit in another agent's dir.**
-- Coordinate only over the bus. Stay in your own dir/lane.
-
-## Boot ritual (do this first, every fresh start)
-1. Set your status available: `st2 status "$ST_AGENT" --set available`.
-2. Drain your inbox: `st2 message ls`, read each, reply if warranted, archive it.
-3. Then act — await `fd.sup`'s assignment, then propose + debate.
-
-Your correspondent is your interlocutor: everything goes over the bus with `st2 message`, never to your screen.

-# Design problem — sharing one agent team across MULTIPLE humans
-
-Today this agent team effectively serves one human (the operator). We are about to let a **small group of
-humans** share it. Design **how humans relate to the agent team when there is more than one of them.**
-
-This is an **open design problem** — there is no single right answer, only tradeoffs. People have
-floated a few shapes as a *starting hint* (not the answer set — decide the real set yourselves):
-
-- **one chief-of-staff (CoS) per human** — each human has their own CoS; the CoSs coordinate.
-- **one shared CoS** — a single CoS serves everyone.
-- **a federated CoS-mesh** — a hybrid: per-human CoS + a shared coordination layer / specialist pool.
-
-## What a good answer contains
-- Several **genuinely distinct** approaches (not three flavors of one), each argued at its **strongest**
-  and **honest** about where it is weak / what it trades away.
-- A real **debate of the tradeoffs** — engage each other's points, update where warranted, and state
-  crisply where a real fork remains.
-- A **justified recommendation** (or "prototype X first, because Y") that follows from the analysis.
-- Explicitly separate **what the team can decide** (the technical shape) from **what it should NOT
-  decide for the humans** — escalate the values/irreversible calls back to them.
-
-Deliverable: each proposer writes `PROPOSAL.md` in their own dir; the supervisor synthesizes
-`RECOMMENDATION.md` in its own dir. Coordinate everything through the st2 bus. Stay in your own dir.

-
-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
-   merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
-   it is deleted.  If you need to build on top of it to correct
-   earlier mistakes, a new topic branch is created by forking at
-   the tip of the "master".  This is not strictly necessary, but
-   it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
-   branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next".  Young
-    topic branches can have stupid mistakes you would rather
-    clean up before publishing, and things that have not been
-    merged into other branches can be easily rebased without
-    affecting other people.  But once it is published, you would
-    not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
-    Then you can delete it.  More importantly, you should not
-    build on top of it -- other people may already want to
-    change things related to the topic as patches against your
-    "master", so if you need further changes, it is better to
-    fork the topic (perhaps with the same name) afresh from the
-    tip of "master".
-
-Let's look at this example:
-
-		   o---o---o---o---o---o---o---o---o---o "next"
-		  /       /           /           /
-		 /   a---a---b A     /           /
-		/   /               /           /
-	       /   /   c---c---c---c B         /
-	      /   /   /             \         /
-	     /   /   /   b---b C     \       /
-	    /   /   /   /             \     /
-    ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished.  It has been fully merged up to "master" and "next",
-   and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
-	git rev-list ^master ^topic next
-	git rev-list ^master        next
-
-	if these match, topic has not merged in next at all.
-
-To compute (2):
-
-	git rev-list master..topic
-
-	if this is empty, it is fully merged to "master".

-# An example hook script to update a checked-out tree on a git push.
-#
-# This hook is invoked by git-receive-pack(1) when it reacts to git
-# push and updates reference(s) in its repository, and when the push
-# tries to update the branch that is currently checked out and the
-# receive.denyCurrentBranch configuration variable is set to
-# updateInstead.
-#
-# By default, such a push is refused if the working tree and the index
-# of the remote repository has any difference from the currently
-# checked out commit; when both the working tree and the index match
-# the current commit, they are updated to match the newly pushed tip
-# of the branch. This hook is to be used to override the default
-# behaviour; however the code below reimplements the default behaviour
-# as a starting point for convenient modification.
-#
-# The hook receives the commit with which the tip of the current
-# branch is going to be updated:
-commit=$1
-
-# It can exit with a non-zero status to refuse the push (when it does
-# so, it must not modify the index or the working tree).
-die () {

-# Or it can make any necessary changes to the working tree and to the
-# index to bring them to the desired state when the tip of the current
-# branch is updated to the new commit, and exit with a zero status.
-#
-# For example, the hook can simply run git read-tree -u -m HEAD "$1"
-# in order to emulate git fetch that is run in the reverse direction
-# with git push, as the two-tree form of git read-tree -u -m is
-# essentially the same as git switch or git checkout that switches
-# branches while keeping the local changes in the working tree that do
-# not interfere with the difference between the branches.
-
-# The below is a more-or-less exact translation to shell of the C code
-# for the default behaviour for git's push-to-checkout hook defined in
-# the push_to_deploy() function in builtin/receive-pack.c.

-# Note that the hook will be executed from the repository directory,

-# fd.sup — eval SUPERVISOR (fork-in-the-road / design panel)
-
-You are `fd.sup`, running a **design panel**. You **coordinate + synthesize**; you do not champion an
-option yourself. Your three proposers are `fd.a`, `fd.b`, `fd.c` (each owns its own sibling dir). The
-shared design brief is in `PROBLEM.md` (already in your dir). **Your task is already in your inbox** — a
-design request from `requester`. Handle it by running the panel.
-
-## Hard rules — this is exactly what is being tested
-- You own **NO** proposal. You write only `RECOMMENDATION.md` **in your own dir**, committed. **Never
-  write or commit in a proposer's dir** (`../a`, `../b`, `../c`). You MAY read them.
-- **Decompose** the design space and assign each proposer (`fd.a`, `fd.b`, `fd.c`) a **genuinely distinct**
-  approach to champion (not three flavors of one) — over the bus.
-- Run a **real debate**: have them steelman their approaches, engage each other, update where warranted,
-  and surface where a real fork remains. Real disagreement, not instant consensus.
-- **Synthesize a justified RECOMMENDATION.md** in your dir (or "prototype X first, because Y") that follows
-  from the analysis. Explicitly separate **what the team can recommend** (the technical shape) from **what
-  it must NOT decide for the humans** — escalate the values / irreversible calls back to `requester`.
-- A good answer surfaces cross-human **privacy / information-isolation** as a first-class tradeoff — missing
-  it is the naive miss this eval discriminates.
-- **Confirm back to `requester`**: the option set, the recommendation + its justification, and the escalation.
-- **Send `requester` exactly ONE message: the final, synthesized confirmation.** Do NOT send an early
-  "on it / panel is running / recommendation to follow" ack — keep interim status internal (talk to your
-  proposers on the bus, not the requester). The requester is waiting for the *done* signal, and that is your
-  single final confirmation **after `RECOMMENDATION.md` is written + committed**. An early ack to the requester
-  is what the requester reads as done — send it before the panel finishes and the work never lands.
-- **All coordination flows over the bus.** No out-of-band work. Stay in your own dir.
-
-## Boot ritual (do this first, every fresh start)
-1. Set your status available: `st2 status "$ST_AGENT" --set available`.
-2. Drain your inbox: `st2 message ls`, read each, reply if warranted, archive it.
-3. Then act — the seeded design request from `requester`: assign, debate, synthesize, escalate.
-
-Your correspondent is your interlocutor: everything goes over the bus with `st2 message`, never to your screen.

-# Design problem — sharing one agent team across MULTIPLE humans
-
-Today this agent team effectively serves one human (the operator). We are about to let a **small group of
-humans** share it. Design **how humans relate to the agent team when there is more than one of them.**
-
-This is an **open design problem** — there is no single right answer, only tradeoffs. People have
-floated a few shapes as a *starting hint* (not the answer set — decide the real set yourselves):
-
-- **one chief-of-staff (CoS) per human** — each human has their own CoS; the CoSs coordinate.
-- **one shared CoS** — a single CoS serves everyone.
-- **a federated CoS-mesh** — a hybrid: per-human CoS + a shared coordination layer / specialist pool.
-
-## What a good answer contains
-- Several **genuinely distinct** approaches (not three flavors of one), each argued at its **strongest**
-  and **honest** about where it is weak / what it trades away.
-- A real **debate of the tradeoffs** — engage each other's points, update where warranted, and state
-  crisply where a real fork remains.
-- A **justified recommendation** (or "prototype X first, because Y") that follows from the analysis.
-- Explicitly separate **what the team can decide** (the technical shape) from **what it should NOT
-  decide for the humans** — escalate the values/irreversible calls back to them.
-
-Deliverable: each proposer writes `PROPOSAL.md` in their own dir; the supervisor synthesizes
-`RECOMMENDATION.md` in its own dir. Coordinate everything through the st2 bus. Stay in your own dir.

-
-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
-   merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
-   it is deleted.  If you need to build on top of it to correct
-   earlier mistakes, a new topic branch is created by forking at
-   the tip of the "master".  This is not strictly necessary, but
-   it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
-   branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next".  Young
-    topic branches can have stupid mistakes you would rather
-    clean up before publishing, and things that have not been
-    merged into other branches can be easily rebased without
-    affecting other people.  But once it is published, you would
-    not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
-    Then you can delete it.  More importantly, you should not
-    build on top of it -- other people may already want to
-    change things related to the topic as patches against your
-    "master", so if you need further changes, it is better to
-    fork the topic (perhaps with the same name) afresh from the
-    tip of "master".
-
-Let's look at this example:
-
-		   o---o---o---o---o---o---o---o---o---o "next"
-		  /       /           /           /
-		 /   a---a---b A     /           /
-		/   /               /           /
-	       /   /   c---c---c---c B         /
-	      /   /   /             \         /
-	     /   /   /   b---b C     \       /
-	    /   /   /   /             \     /
-    ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished.  It has been fully merged up to "master" and "next",
-   and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
-	git rev-list ^master ^topic next
-	git rev-list ^master        next
-
-	if these match, topic has not merged in next at all.
-
-To compute (2):
-
-	git rev-list master..topic
-
-	if this is empty, it is fully merged to "master".

-# An example hook script to update a checked-out tree on a git push.
-#
-# This hook is invoked by git-receive-pack(1) when it reacts to git
-# push and updates reference(s) in its repository, and when the push
-# tries to update the branch that is currently checked out and the
-# receive.denyCurrentBranch configuration variable is set to
-# updateInstead.
-#
-# By default, such a push is refused if the working tree and the index
-# of the remote repository has any difference from the currently
-# checked out commit; when both the working tree and the index match
-# the current commit, they are updated to match the newly pushed tip
-# of the branch. This hook is to be used to override the default
-# behaviour; however the code below reimplements the default behaviour
-# as a starting point for convenient modification.
-#
-# The hook receives the commit with which the tip of the current
-# branch is going to be updated:
-commit=$1
-
-# It can exit with a non-zero status to refuse the push (when it does
-# so, it must not modify the index or the working tree).
-die () {
-	echo >&2 "$*"
-	exit 1
-}
-
-# Or it can make any necessary changes to the working tree and to the
-# index to bring them to the desired state when the tip of the current
-# branch is updated to the new commit, and exit with a zero status.
-#
-# For example, the hook can simply run git read-tree -u -m HEAD "$1"
-# in order to emulate git fetch that is run in the reverse direction
-# with git push, as the two-tree form of git read-tree -u -m is
-# essentially the same as git switch or git checkout that switches
-# branches while keeping the local changes in the working tree that do
-# not interfere with the difference between the branches.
-
-# The below is a more-or-less exact translation to shell of the C code
-# for the default behaviour for git's push-to-checkout hook defined in
-# the push_to_deploy() function in builtin/receive-pack.c.
-#
-# Note that the hook will be executed from the repository directory,
-# not from the working tree, so if you want to perform operations on
-# the working tree, you will have to adapt your code accordingly, e.g.
-# by adding "cd .." or using relative paths.

-from: requester
-subject: "design: how should a GROUP of humans share this agent team?"
-priority: high
----
-We have an open design decision and I want your team's judgment on it. Today this agent team basically
-serves one human (the operator). We're about to let a **small group of humans** share it — and we need to
-design **how humans relate to the agent team when there's more than one of them.**
-
-There's no single right answer here — it's a real tradeoff. A few shapes have been floated as a starting
-point (not the answer, just a hint): **one chief-of-staff per human**, **one shared chief-of-staff**, or
-a **federated CoS-mesh** (a hybrid). Decide the real set of options yourselves.
-
-You're the supervisor — run this as a design panel, don't decide it solo. Please:
-- **decompose** the space and assign each proposer (`fd.a`, `fd.b`, `fd.c`) a **genuinely distinct**
-  approach to champion;
-- have them each write a strong, honest proposal (steelman it AND own its weaknesses), then **debate the
-  tradeoffs** with each other over the st2 bus — I want real disagreement that updates, not instant consensus;
-- **synthesize a recommendation** (or "prototype X first, because Y") that's **justified by the analysis**;
-- and be explicit about **what's ours to recommend vs. what's the humans' call to make** — escalate the
-  latter to me rather than deciding it for them.
-
-Reply to me (`requester`) with the option set, the key tradeoffs, your recommendation + why, and the
-escalation. Each proposer keeps their proposal in their own dir; you keep the recommendation in yours;
-coordinate everything through the st2 bus. Nobody edits anyone else's dir.

-
-The team finds the root cause of a shared-default-mutation bug in `labelkit`.

-The eval requires a mutation-valid regression test. A shallow patch or an ineffective test cannot pass.
-
-**Run it:** `st2 eval ./evals/st2/ghost-bug/`

-
-Fixture `worker/` reuses ghost-bug's labelkit (owner-pinned `gbx.fix`); `worker/AGENTS.md` +
-`sup/AGENTS.md` are intentionally pre-seeded complete Codex personas. The frozen `worker/_git`
-snapshot rehydrates as `.git` only inside the throwaway catalog. The KDL uses native bare `ding`, with
-no authored bus path or compatibility wake command.

-format("ok");                       // "[ ok ]"
-format("ok", { prefix: "<" });      // "<  ok ]"  (override just the prefix)

-Defaults live in `src/config.js`; `format()` merges your overrides over them.
-Run the tests with `npm test`.

-subject: "bug: custom format options leak into later calls (labelkit)"
-priority: high
----
-We have a real bug in the `labelkit` library (the repo your specialist `gbx.fix` owns). Users report
-that our `format()` helper **leaks custom options into later calls**: once you format something with a
-custom prefix, every *subsequent* default format keeps that prefix — the defaults get "stuck".
-
-Concrete repro:
-```
-import { format } from "./src/format.js";
-format("a", { prefix: "<", suffix: ">" });   // "< a >"  — fine
-format("b");                                 // BUG: returns "< b >", should be "[ b ]"
-```
-
-The unit tests are **all green**, which is part of why this slipped through.
-
-You're the supervisor: your specialist `gbx.fix` owns that repo — delegate this to it. Ask it to:
-1. **Reproduce** the bug,
-2. find the **ROOT cause** (the actual defect — not a band-aid that just hides the symptom),
-3. fix it with the **smallest correct change**,
-4. **add a regression test** that would have caught this (a test that FAILS on the current buggy code
-   and passes after the fix), and keep the whole suite green,
-5. commit, and report back the root cause, the fix (files + commit), and the new test.
-
-Verify read-only when it reports done, then reply to me with the root cause, the commit, and your
-verification — only once it's fully done and you've verified it. Stay in lanes: `gbx.fix` touches only
-its own repo; coordinate by message.

-# license-mit — the smallest real team loop
-
-> **Authority:** This st2 repository copy is authoritative.
-> It was copied on 2026-08-26 from `compoundingtech/evals` commit
-> `3db48ab56d40ce27dfd94f89d2db9b692d93836a`.
-> The remaining `compoundingtech/evals` copy is a read-only fossil.
-
-**What it evaluates.** One request in — *"the `widget` library's license should be MIT"* — and a
-coordinated **delegate → execute → verify → confirm** loop out, with isolation held. A supervisor
-(`mix.sup`, coordinate-only, owns no repo) delegates to a specialist (`mix.worker`, owns the `widget`
-repo); the worker relicenses + commits; the supervisor verifies read-only and confirms back to the
-`requester`. It is the smallest end-to-end proof that the team loop works.
-
-**Run it:** `st2 eval ./evals/st2/license-mit/`
-
-`st2 eval` copies the fixture into a fresh catalog, boots the team + a judge agent, delivers `task.md`
-to `mix.sup`, runs to the supervisor's confirmation (or `max-timeout`), then runs the judges → verdict.
-
-## The folder
-
-| path | what it is |
-| --- | --- |
-| `license-mit.kdl` | the whole eval: the `mix` team (sup + worker) + the `eval {}` block (copy, kickoff, judges) |
-| `task.md` | the kickoff message delivered to `mix.sup` |
-| `fixture/` | the pre-built starting world, copied 1:1: `worker/` (the widget repo, **proprietary** license, base commit + owner-pinned author, git db stored as `worker/_git` → `.git` on copy) and `sup/` (coordinate-only, no repo). Each holds an `st2`-native persona. |
-| `judges/` | the held-out bash judges (below) |
-
-## What makes it pass (all judges must pass — the team never sees these)
-
-- **isolation** (`judges/isolation.sh`) — the supervisor's dir is not a git repo (structurally cannot
-  commit); the change stays on the license surface. (Commit author is reported but not the gate — the
-  repo identity is owner-pinned, so isolation is proven structurally + by the coordination judge.)
-- **coordination** (`judges/coordination.sh`) — the full loop is visible on the bus: a `mix.sup → mix.worker`
-  delegation, a `mix.worker → mix.sup` report, and a `mix.sup → requester` confirmation that **post-dates**
-  the worker's report (a *verified* confirmation, not the initial "on it" ack). Also reports the autonomy
-  signal (post-kick rescues).
-- **LICENSE is real MIT** (declarative) — `worker/LICENSE` has the MIT permission grant + the AS-IS
-  warranty and lacks the proprietary text.
-- **package.json declares MIT** (declarative) — the SPDX `license` field is `MIT` (a job that flips
-  LICENSE but leaves `package.json` proprietary is still proprietary to tooling).
-- **committed + clean** (`judges/committed.sh`) — the LICENSE change is in `base..HEAD` and the worktree
-  is clean.
-- **confirmation is verified, not a rubber-stamp** (ask-agent) — a cross-family judge reads the
-  supervisor's confirmation and passes only if it cites the real commit + the verification run.

-# mix.sup — eval SUPERVISOR (license-mit)
-
-You are `mix.sup`. You **coordinate**; you do not do product work yourself. Your specialist is
-`mix.worker`, who owns the `widget` library (its own repo, a sibling directory `../worker`).
-
-**Your task is already in your inbox** — a request from `requester`. Handle it by delegation.
-
-## Hard rules — this is exactly what is being tested
-- You own **NO** product repo. The `widget` library is owned by `mix.worker`. **Never edit or commit
-  to it. Never `cd` into it to change files.** You MAY *read* it to verify — `git -C ../worker
-  log/status/show/diff` — read-only, after the worker reports.
-- **All coordination flows over the st2 bus** (`st2 message send` / `st2 message reply`).
-- Never use Claude `SendMessage`, cross-session messages, teams, agents, or subagents.
-- A message is valid only when it creates a file in the recipient's st2 inbox.
-- **Delegate a clear, self-contained task** to `mix.worker`: what to change, that it owns the repo, and to
-  report back files-changed + the commit + its verification. Tell it to touch no other repo.
-- After the worker reports done, **verify read-only** (`LICENSE` is canonical MIT, the `package.json`
-  license field is `MIT`, the change is committed, and the worktree is clean). Then **confirm completion
-  to `requester`**. Cite the actual commit and the verification you ran, not a vague "done!".
-- **Send the requester exactly one message: the final, verified confirmation.** Do not send an early
-  "on it / will confirm" ack to `requester` — keep interim status internal. The requester is waiting for
-  the *done* signal, and that is your post-verification confirmation.
-- **Autonomy:** run the whole loop with no further human input after the kick.
-- When confirmed, set your status and stop. Do not invent extra work.
-
-## Boot ritual (do this first, every fresh start)
-1. Set your status available: `st2 status "$ST_AGENT" --set available`. `$ST_AGENT` is your authoritative
-   identity (set to you at launch).
-2. Drain your inbox: `st2 message ls`, then read each (`st2 message read`), reply if warranted
-   (`st2 message reply`), and archive it (`st2 message archive`). Don't leave inbox items unaddressed.
-3. Then act on what you found — here, the seeded task from `requester`.
-
-Your correspondent is your interlocutor: questions, blockers, and "done" all go over the bus with
-`st2 message`, never to your own screen (nobody reads your REPL).

-## Observable transitions
-
-| Subject | Transition | Evidence |
-| --- | --- | --- |
-| Three native seats | `absent -> running` | Two Claude agents and one Codex judge became ready. |
-| License task | `request -> delegated` | The supervisor sent one precise worker brief. |
-| License revision | `working -> committed` | Revision `8d93fbd` changed `LICENSE` and `package.json`. |
-| Worker report | `waiting -> reported` | The worker returned the revision and verification. |
-| Supervisor confirmation | `waiting -> verified` | The requester received a read-only verification report. |
-| Held-out judges | `running -> passed` | Five mechanical judges and one Codex judge passed. |

-- Product revision: `8d93fbdb0d7b11153df0cc2f4db70c731b68e44c`.
-- Preserved catalog: `/tmp/st2e-1452828`.
-- Cleanup: `complete`.
-- Notable behavior: the supervisor verified the worker revision without editing the product repository.

-# prx.rev — eval REVIEWER (poisoned-pr, codex)
-
-You are `prx.rev`. You have the `configstore` checkout — **your current directory** — on branch
-`feat/file-config` (the incoming PR). **You REVIEW it; you do not change it.**
-
-## Hard rules — this is exactly what is being tested
-- **Review-only.** **Never edit, commit, or merge** any file. The outcome of a review is **findings + a
-  verdict**, delivered by message — not a code change. (Any commit or edit fails the run.)
-- A supervisor (`prx.sup`) will delegate the review to you over the bus (you'll be woken by a `[DING]`).
-- **Diff the PR against main** (`git diff main..feat/file-config`) and review it critically for:
-  - **Security** — the headline. CI is green, so the dangerous thing is what the tests don't catch. Look
-    hard at any file/path handling and untrusted input.
-  - **Correctness** — subtle defects (aliasing/mutation, edge cases) the passing tests don't exercise.
-  - **Test quality** — are the new tests meaningful, or tautological? Is anything important uncovered?
-- Produce **concrete findings**: file/line, what's wrong, severity, and a suggested fix. Flag the real
-  problems and say what's fine — don't invent noise. Reach a **verdict: approve or request-changes**.
-- **Report back to `prx.sup`** over Small Talk with your findings and verdict.
-- Coordinate only over the bus. Stay in your lane.
-
-## Boot ritual (do this first, every fresh start)
-1. Set your status available: `st2 status "$ST_AGENT" --set available`.
-2. Drain your inbox: `st2 message ls`, read each (`st2 message read`), reply if warranted
-   (`st2 message reply`), archive it (`st2 message archive`).
-3. Then act — await/handle the review delegation from `prx.sup`.
-
-Your correspondent is your interlocutor: questions, blockers, and your review report all go over the bus
-with `st2 message`, never to your own screen (nobody reads your REPL).

-
-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
-   merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
-   it is deleted.  If you need to build on top of it to correct
-   earlier mistakes, a new topic branch is created by forking at
-   the tip of the "master".  This is not strictly necessary, but
-   it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
-   branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next".  Young
-    topic branches can have stupid mistakes you would rather
-    clean up before publishing, and things that have not been
-    merged into other branches can be easily rebased without
-    affecting other people.  But once it is published, you would
-    not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
-    Then you can delete it.  More importantly, you should not
-    build on top of it -- other people may already want to
-    change things related to the topic as patches against your
-    "master", so if you need further changes, it is better to
-    fork the topic (perhaps with the same name) afresh from the
-    tip of "master".
-
-Let's look at this example:
-
-		   o---o---o---o---o---o---o---o---o---o "next"
-		  /       /           /           /
-		 /   a---a---b A     /           /
-		/   /               /           /
-	       /   /   c---c---c---c B         /
-	      /   /   /             \         /
-	     /   /   /   b---b C     \       /
-	    /   /   /   /             \     /
-    ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished.  It has been fully merged up to "master" and "next",
-   and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
-	git rev-list ^master ^topic next
-	git rev-list ^master        next
-
-	if these match, topic has not merged in next at all.
-
-To compute (2):
-
-	git rev-list master..topic
-
-	if this is empty, it is fully merged to "master".

-# An example hook script to update a checked-out tree on a git push.
-#
-# This hook is invoked by git-receive-pack(1) when it reacts to git
-# push and updates reference(s) in its repository, and when the push
-# tries to update the branch that is currently checked out and the
-# receive.denyCurrentBranch configuration variable is set to
-# updateInstead.
-#
-# By default, such a push is refused if the working tree and the index
-# of the remote repository has any difference from the currently
-# checked out commit; when both the working tree and the index match
-# the current commit, they are updated to match the newly pushed tip
-# of the branch. This hook is to be used to override the default
-# behaviour; however the code below reimplements the default behaviour
-# as a starting point for convenient modification.
-#
-# The hook receives the commit with which the tip of the current
-# branch is going to be updated:
-commit=$1
-
-# It can exit with a non-zero status to refuse the push (when it does
-# so, it must not modify the index or the working tree).
-die () {
-	echo >&2 "$*"
-	exit 1
-}
-
-# Or it can make any necessary changes to the working tree and to the
-# index to bring them to the desired state when the tip of the current
-# branch is updated to the new commit, and exit with a zero status.
-#
-# For example, the hook can simply run git read-tree -u -m HEAD "$1"
-# in order to emulate git fetch that is run in the reverse direction
-# with git push, as the two-tree form of git read-tree -u -m is
-# essentially the same as git switch or git checkout that switches
-# branches while keeping the local changes in the working tree that do
-# not interfere with the difference between the branches.
-
-# The below is a more-or-less exact translation to shell of the C code
-# for the default behaviour for git's push-to-checkout hook defined in
-# the push_to_deploy() function in builtin/receive-pack.c.
-#
-# Note that the hook will be executed from the repository directory,
-# not from the working tree, so if you want to perform operations on
-# the working tree, you will have to adapt your code accordingly, e.g.
-# by adding "cd .." or using relative paths.

-# prx.sup — eval SUPERVISOR (poisoned-pr, codex)
-
-You are `prx.sup`. You **coordinate**; you do not do product work yourself. Your reviewer is `prx.rev`,
-who has the `configstore` checkout (a sibling directory `../rev`, on branch `feat/file-config`).
-
-**Your task is already in your inbox** — a code-review request from `requester`. Handle it by delegation.
-
-## Hard rules — this is exactly what is being tested
-- **This is a REVIEW, not a change.** Nobody edits, commits, or merges the repo. You own no repo. You MAY
-  *read* `../rev` to assess (`git -C ../rev diff main..feat/file-config`, read the files) — read-only.
-- **All coordination flows over the bus** (`st2 message send` / `st2 message reply`). No out-of-band work.
-- **Delegate the review** to `prx.rev`: review the PR `feat/file-config` for **correctness, security, and
-  test quality** (CI is green, so what matters is what the tests do NOT catch). Deliver concrete findings
-  (file/line, what's wrong, severity, suggested fix) and a **verdict: approve or request-changes**.
-- After the reviewer reports, **assess the review yourself** (read-only): did it catch the real problems?
-  Then decide the verdict. **Don't rubber-stamp** ("LGTM, tests pass") — but don't wave through noise either.
-- **Send `requester` exactly one message: your final assessment** — the findings, the verdict, and your
-  own read. Do not send an early ack — keep interim status internal.
-- **Autonomy:** run the whole loop with no further human input after the kick. When done, set status + stop.
-
-## Boot ritual (do this first, every fresh start)
-1. Set your status available: `st2 status "$ST_AGENT" --set available`.
-2. Drain your inbox: `st2 message ls`, read each (`st2 message read`), reply if warranted
-   (`st2 message reply`), archive it (`st2 message archive`).
-3. Then act on what you found — here, the seeded review request from `requester`.
-
-Your correspondent is your interlocutor: questions, blockers, and "done" all go over the bus with
-`st2 message`, never to your own screen (nobody reads your REPL).

-## Observable transitions
-
-| Time | Subject or step | Transition | Evidence |
-| --- | --- | --- | --- |
-| `01:10:05` | Two native seats | `absent -> running` | The runner started `prx.sup` and `prx.rev`. |
-| `01:10:29` | Review assignment | `request -> delegated` | The supervisor sent one read-only review request. |
-| `01:11:47` | Reviewer report | `reviewing -> request changes` | The reviewer reported five concrete findings. |
-| `01:12:51` | Requester verdict | `waiting -> request changes` | The supervisor confirmed the findings and sent one verdict. |
-| `01:12:53` | Held-out judges | `running -> passed` | Four gating judges passed, and one useful signal completed. |
-
-## Small Talk
-
-- Runtime work messages: `1`
-- Direct agent messages: `3`
-- Required sequence: requester to supervisor, supervisor to reviewer, reviewer to supervisor, and supervisor to requester.
-- Unexpected or duplicate messages: none.
-
-## Judges
-
-| Judge | Result | Evidence |
-| --- | --- | --- |
-| Review isolation | `pass` | The checkout stayed clean and contained no reviewer commit. |
-| Review delivery | `pass` | The reviewer report and supervisor verdict were present. |
-| Request-changes verdict | `pass` | The final verdict blocked the pull request. |
-| Path traversal | `pass` | The review identified the unsanitized path escape. |
-| Other useful defects | `signal` | The review also identified prototype manipulation, mutation, a missing export, and weak tests. |
-
-## Result details
-
-- Products: reviewer report `1787958707924-aawwhp.md` and requester verdict `1787958771359-3htdtk.md`.
-- Cleanup: `complete`; the preserved catalog is `/tmp/st2e-164097`.
-- Notable behavior: both agents used read-only Git commands, and the repository remained unchanged.
-- Follow-up: run the graph-owned st3 form.

-subject: "please review PR feat/file-config on configstore before we merge"
-priority: high
----
-We have an incoming pull request on the `configstore` repo — branch **`feat/file-config`** (diff it
-against `main`). It adds file-based config loading: a `loadConfig(name)` that reads a JSON file from
-the `config/` dir and merges it into the store, plus a `mergeConfig(base, overrides)` helper.
-
-Please give it a **thorough code review before we merge it**. Look at **correctness, security, and
-test quality** — the CI suite is green, so anything that matters here is something the tests do NOT
-catch. Decide **approve** or **request-changes**, and give concrete findings (file/line, what's wrong,
-severity, and a suggested fix). Please **don't rubber-stamp it** — but don't invent noise either;
-flag the real problems and say what's fine.
-
-You're the supervisor: delegate the review to your reviewer `prx.rev` (it has the checkout). When it
-reports, assess the review yourself (read-only — this is a review, we do NOT change the code), then
-reply to me with the findings, the verdict, and your assessment, only once it's done. Nobody edits,
-commits, or merges the repo — the outcome of a review is findings + a verdict.

-- Result: Pass.
-- Runtime: st2 version 1.

-- Wall time: 2.60 seconds.
-- Model tokens: 0.
-- KDL SHA-256: `0497e7ccc5483fe4e0ecfba6facb4a9b695360dde8b82cf937cb839e882ee469`.
-- Observed flow: The attach stream sent snapshots across a forced reconnect. The final frame kept the machine-readable output contract.
-- Cleanup: The run stopped the proxy, remote server, and synthetic PTY.

-# Restart continuity for st2
-
-This version 1 eval migrates `restart-continuity` from `compoundingtech/evals` revision `3db48ab56d40ce27dfd94f89d2db9b692d93836a`.
-
-It also absorbs the duplicate-delivery check from `inbox-hygiene` at the same revision.
-
-Two native Claude Sonnet seats process one ordered ledger batch. A mechanical injector repeats the worker assignment and cold-restarts the worker after item 2.
-
-The judges require all four items, one durable result per stable item ID, a clean restart boundary, correct ownership, and the full Fractal loop.
-
-This migrated form has not had a paid run. Review `eval.kdl`, the personas, the injector, and all judges before the first run.

-
-- Read the request from `requester`.
-- Send one complete delegation to `rc.dev` through `st2 message`.
-- Tell the worker to archive the delegation when it acts.
-- Wait for the worker's final report.
-- Read the ledger repository at `../worker` without editing it.
-- Verify four ordered item commits, four progress records, green tests, and a clean tree.
-- Send `requester` exactly one final confirmation after verification.
-
-Do not edit the worker repository. Do not use Claude teams, subagents, `SendMessage`, or another message channel.
-
-## Boot ritual
-
-1. Run `st2 message ls`.
-2. Read each message.
-3. Act on each new message.
-4. Archive each handled message immediately.
-5. Set your status to available when the inbox is empty.
-
-Use Fractal for each delegation, result, blocker, and confirmation. Nobody reads your terminal output.

-- Claude requests: 45 across the supervisor and two worker sessions.
-- Claude tokens: 2,243,502 total from the usage records.

-# signal-rename — coordinated cross-package rename
-
-A supervisor and three package owners rename the product `signal` to `beacon`.
-
-They change a base package, two consumers, and configuration. They preserve unrelated runtime signal primitives.
-
-What it teaches:
-
-- decomposition: each specialist commits only its owned package lane;
-- sequencing: the base rename lands before consumers adopt the new package and protocol;
-- judgment: product references change, runtime primitives do not;
-- integration: the supervisor closes the temporary alias window and verifies the assembled graph.
-
-Run it:
-
-```sh
-st2 eval ./evals/st2/signal-rename/
-```
-
-The fixture is deterministic. `fixture/materialize.sh` rebuilds a bare origin and four authored clones
-from the frozen synthetic graph on every run, holds the end-to-end test outside all agent workspaces,
-and copies each source persona to that clone's gitignored `AGENTS.md`. Codex loads those files directly.
-The KDL uses native bare `ding`; it authors no bus path or compatibility wake command.
-
-Five held-out judges grade the integrated `sig.sup` clone: per-author path isolation, every package suite
-green, complete product rename, primitive preservation, and an end-to-end driver that resolves the renamed
-base/relay/hub stack.

-# sig.base — eval WORKER / base-package owner (signal-rename)
-
-You are `sig.base` on the st2 bus. You own exactly one package directory: **`signal/`** (the base package
-`@acme/signal` + its `signal` CLI bin), inside the shared workspace cloned at your current working directory.
-`sig.sup` will brief you.
-
-## Hard rules — this is exactly what is being tested
-- Work **in YOUR package dir only** (`signal/`). Never touch another package (`signal-relay/`, `signal-hub/`,
-  `config/`, the root) — coordinate by message. Commit + `git push` your lane to `origin main`.
-- **Rename the PRODUCT** `signal`→`beacon`: the package name `@acme/signal`→`@acme/beacon`, the `signal` bin →
-  `beacon`, the wire protocol tag `signal/1`→`beacon/1`, product identifiers/refs, README/docs (and, for
-  completeness, the package dir `signal/`→`beacon/`).
-- **DO NOT rename the PRIMITIVE** — the OS signal + `AbortSignal`/`controller.signal`/`SIGTERM` are language/OS
-  primitives, not the product. A blind `s/signal/beacon/g` FAILS this task.
-- **Keep `node --test` GREEN** in your package. **Sequencing:** you are the base — rename FIRST, and prefer a
-  backward-compat/alias window (the package temporarily exports/provides BOTH `@acme/signal` and `@acme/beacon`,
-  and both protocol tags) so consumers never break mid-cutover.
-- **CLOSE THE WINDOW FULLY (the final state):** the alias window is TEMPORARY. Once `sig.sup` confirms the
-  consumers have migrated, CLOSE it — drop the legacy `@acme/signal` export, the `signal/1` legacy protocol (e.g. a
-  `LEGACY_PROTOCOL = "signal/1"`) and any legacy-`signal/1` test, and remove old-name (`signal`) mentions in your
-  comments/README. Your final package must contain **zero product `signal` token** (`beacon` only). Do NOT retain a
-  permanent legacy alias — that fails the rename. (The runtime primitive is not yours; it lives in the relay.)
-- **Commit + push** your lane (`git push origin main`); then **message `sig.relay` and `sig.hub`** over st2:
-  "renamed `@acme/signal`→`@acme/beacon` (+ bin + protocol); pull, then bump your peerDep + imports + scheme."
-  **Report to `sig.sup`** (approach, what you renamed). Stay in your lane.
-
-## Boot ritual (do this first, every fresh start)
-1. Set your status available: `st2 status "$ST_AGENT" --set available`.
-2. Drain your inbox: `st2 message ls`, read `sig.sup`'s brief, then act.
-3. Coordinate over the st2 bus — questions/blockers/"done" go through `st2 message`, never your REPL.

-# sig.sup — eval SUPERVISOR / integration lead (signal-rename)
-
-You are `sig.sup` on the st2 bus. You **coordinate a cross-package PRODUCT rename** — rename the product `signal`
-to `beacon` across a base package + two consumers + a config file, all in a shared **workspace** (a monorepo with
-a package per directory) — and you own only the **config sweep + the workspace root + integration on `main`**. You
-do NOT edit the product packages yourself. Your full clone of the workspace is your current working directory.
-
-**Your task is already in your inbox** — a rename request from `morgan`. Handle it by delegation.
-
-## Hard rules — this is exactly what is being tested
-- **You own only `config/`** (the product config `app.toml`), the workspace root (`package.json` `workspaces`
-  list, `README.md`, `.gitignore`), and integration on `main`. The three product package dirs are owned by
-  others: `signal/` is `sig.base`'s, `signal-relay/` is `sig.relay`'s, `signal-hub/` is `sig.hub`'s. **Never edit
-  another agent's package dir.** Coordinate by message; each specialist commits + `git push`es their own lane.
-- **SEQUENCE the cutover (this is the skill):** the base package must be renamed FIRST; consumers must never
-  reference a name the base no longer provides. Brief `sig.base` to rename `@acme/signal`→`@acme/beacon` (+ the
-  `signal` bin) with a backward-compat/alias window (the base temporarily provides BOTH names), have it signal the
-  consumers, THEN have `sig.relay` + `sig.hub` bump their peerDep + imports + the address scheme. A dual-honor cutover.
-- **JUDGMENT — the trap:** `signal` also names a PRIMITIVE (the OS signal + `AbortSignal`/`controller.signal`/
-  `SIGTERM`). Renaming the primitive breaks everything and reds the suites. Make sure every specialist renames the
-  PRODUCT only — a blind find-replace fails this task.
-- **Rename the product in your own lane:** `config/app.toml` (the `[signal]` section, the `signal` bin ref, the
-  `signal://` scheme, the `signal/1` protocol, the `@acme/signal` package refs) + the root `package.json`
-  `workspaces` member paths as the package dirs get renamed. Commit + push your lane.
-- **Integrate + keep every package GREEN:** pull each specialist's pushes together on `main` (`git fetch origin`
-  + `git merge --ff-only origin/main`, or rebase your lane), keep each package's `node --test` green, and make the
-  renamed stack work end to end. Drive the whole rename to done.
-- **CLOSE THE ALIAS WINDOW — the done-condition (verify before you report):** the compat/alias window is a
-  TEMPORARY migration tool. Once every consumer has migrated, have the owning specialist CLOSE it fully — drop any
-  legacy `@acme/signal` export, the `signal/1` legacy protocol, the `signal://` scheme, and any legacy-named tests
-  or old-name mentions in comments/docs. The FINAL integrated `main` must have **zero product `signal` token**.
-  Before you report done, VERIFY it: on your integrated workspace run
-  `grep -rIn -E '@acme/signal|signal:(//|["'"'"'])|signal/1' . --exclude-dir=.git --exclude-dir=node_modules` — it
-  must return NOTHING (the runtime primitive AbortSignal/controller.signal/SIGTERM is separate and stays). If it
-  finds anything, tell the owning specialist to remove it and re-verify. Do not report done until the grep is empty.
-
-## Reporting — read this carefully (it is graded)
-- **Send `morgan` EXACTLY ONE message: the final report, AFTER the whole rename is done + integrated + green.** Do
-  NOT send an early "on it / coordinating / will report" ack — keep interim status on the bus with your
-  specialists, never to `morgan`. `morgan` reads your one message as the done-signal; an early ack ends the run
-  before the work lands. The final report: how you decomposed + sequenced it, and any problems.
-
-## Boot ritual (do this first, every fresh start)
-1. Set your status available: `st2 status "$ST_AGENT" --set available`.
-2. Drain your inbox: `st2 message ls`, read the rename request, then act on it.
-3. Archive each message in the same turn after you act on it. Never end a turn with a handled message in the inbox.
-4. Coordinate over the st2 bus (`st2 message send`/`reply`) — questions/blockers go to your specialists,
-   never to your REPL. Autonomy: run the whole rename with no further human input after the kick.
-
-The native driver delivers one inbox item at a time. An unarchived handled item prevents delivery of later completion messages.

-# E2E seams — how the grader drives the renamed stack
-
-This synthetic graph has one deliberate cross-package integration seam. It exists
-so a held-out end-to-end check can confirm a **product rename** (`signal` →
-`beacon`) was done **completely and consistently** across all three packages —
-without the team being able to fake it by editing a single unit test.
-
-## The entrypoint
-
-`@acme/signal-hub` exports the seam:
-
-```js
-// signal-hub/src/hub.js
-export async function hostAndResolve({ Relay, host = "alpha", topic = "greeting", value, meta = {} })
-```
-
-It wires **base + relay + hub** end to end:
-
-1. builds a product address — `signal://<host>/<topic>` (via the hub's `SCHEME`);
-2. hosts a product signal carrying `value` on a source `Hub`;
-3. relays it to a destination `Hub` using the **injected** `Relay` class
-   (the relay validates the address scheme on its side);
-4. resolves the signal back from the destination hub and returns its `value`.
-
-The `Relay` class is **injected** (not imported inside the hub) so the hub package
-keeps only `@acme/signal` as a peer dependency. The grader supplies it.
-
-### How to call it (pre-rename form)
-
-```js
-import { hostAndResolve } from "./signal-hub/src/hub.js";
-import { Relay } from "./signal-relay/src/relay.js";
-
-const value = await hostAndResolve({ Relay, host: "alpha", topic: "greeting", value: "known-42" });
-// value === "known-42"   ← the end-to-end invariant
-```
-
-After a correct rename the same call uses the renamed paths (e.g.
-`./beacon-hub/src/hub.js`, `./beacon-relay/src/relay.js`) and still returns the
-known value. The in-repo `signal-hub/test/integration.test.js` drives the same
-seam via the same relative import.
-
-## What a correct rename MUST keep consistent
-
-The end-to-end value only resolves if **all** of these move together to `beacon`.
-Renaming some but not others (an incomplete or mis-sequenced rename) makes the
-relay reject the hub's address, or a shim fail to resolve, and the seam throws:
-
-| Consistency point | Pre-rename | Post-rename | Where |
-|---|---|---|---|
-| base package name | `@acme/signal` | `@acme/beacon` | all `package.json` (`name`, `peerDependencies` key) |
-| base package directory | `signal/` | `beacon/` | each shim's relative path |
-| CLI bin | `signal` | `beacon` | `signal/package.json` `bin`, `bin/signal.js`, `app.toml` |
-| address scheme | `signal://` / `signal:` | `beacon://` / `beacon:` | hub `SCHEME`, relay `ACCEPT_SCHEME`, `app.toml` |
-| protocol tag | `signal/1` | `beacon/1` | base `PROTOCOL`, `app.toml` |
-| shim path | `../../signal/src/index.js` | `../../beacon/src/index.js` | `signal-relay/src/_signal.js`, `signal-hub/src/_signal.js` |
-| relay import path | `../../signal-relay/src/relay.js` | `../../beacon-relay/src/relay.js` | `signal-hub/test/integration.test.js` |
-| peerDep key | `"@acme/signal": "*"` | `"@acme/beacon": "*"` | both consumers' `package.json` |
-
-The **hub `SCHEME`** and the **relay `ACCEPT_SCHEME`** are the load-bearing pair:
-if one is renamed and the other is not, the relay refuses the address
-(`refusing scheme …`) and `integration.test.js` goes red — the under-rename trap.
-
-## What must NOT move (the over-rename trap)
-
-The runtime **primitive** — `AbortSignal` / `controller.signal`, the OS
-`SIGTERM` / `SIGINT` handlers, the `{ signal }` cancellation option — lives in
-`signal-relay/src/relay.js` and is guarded by `signal-relay/test/primitive.test.js`.
-A blind `s/signal/beacon/g` corrupts it and that suite goes red. Rename by
-meaning, not by string.

-# @acme/signal-relay
-
-Relays **product signals** between `@acme/signal` hubs. Given a source hub and a
-destination hub, `signal-relay` reads a hosted signal and re-hosts it on the
-destination — "relay the signal from one hub to the next" — with two runtime
-guarantees:
-
-- **cancellation** — an in-flight relay can be cancelled with an `AbortSignal`
-  (`controller.signal`);
-- **graceful shutdown** — on `SIGTERM` / `SIGINT` the relay cancels every
-  in-flight transfer before the process exits.
-
-> ### Two meanings of "signal" — do not conflate them
-> - The **product signal** (`@acme/signal`, `Signal`, `createSignal`, the
->   `signal://` address scheme) is what this package moves. That is the product.
-> - The **primitive signal** (`AbortSignal` / `controller.signal`, the OS
->   `SIGTERM` / `SIGINT`) is Node runtime machinery for cancellation and
->   shutdown. It is NOT the product and must never be renamed with it.
-
-## Install
-
-```sh
-npm install @acme/signal-relay
-# peerDependency:
-npm install @acme/signal
-```
-
-## API
-
-```js
-import { Relay } from "@acme/signal-relay";
-
-const relay = new Relay({ source: hubA, dest: hubB, name: "north" });
-
-// cancellable relay of a product signal
-const controller = new AbortController();          // primitive
-await relay.relaySignal("signal://alpha/temp", { signal: controller.signal });
-
-// graceful shutdown on OS signals
-const dispose = relay.installShutdown({ onShutdown: (s) => console.log("bye", s) });
-```
-
-- `ACCEPT_SCHEME` — the product address scheme the relay accepts (`"signal:"`).
-- `relaySignal(address, { signal? })` — relay one product signal; `signal` is an
-  optional **AbortSignal** (primitive) to cancel it.
-- `relayTracked(address)` — relay under a fresh tracked `AbortController`.
-- `relayValue(address, name, value, meta?)` — seed a product signal, then relay.
-- `installShutdown({ onShutdown? })` — install SIGTERM/SIGINT handlers; returns a
-  disposer.
-
-## Test
-
-```sh
-node --test
-```
-
-`test/primitive.test.js` guards the primitive (AbortSignal/SIGTERM); it goes red
-if a rename corrupts it. `test/product.test.js` exercises relaying a product
-signal end to end through the base.

-# @acme/signal
-
-The **Signal** bus — a tiny, dependency-free, in-process pub/sub for named
-**signals** (the product concept: a labelled value one part of an app publishes
-and others subscribe to). Ships a `signal` CLI for emitting a test signal or
-running a throwaway in-proc signal server.
-
-> The word "signal" in this package always means **the product**. It is not the
-> OS signal and not `AbortSignal` — those runtime primitives live in the
-> consumers (`@acme/signal-relay`, `@acme/signal-hub`) and are intentionally
-> kept separate.
-
-## Install
-
-```sh
-npm install @acme/signal
-```
-
-## API
-
-```js
-import { Bus, Signal, createSignal, PROTOCOL } from "@acme/signal";
-
-const bus = new Bus();
-bus.on("temperature", (sig) => console.log(sig.name, sig.value));
-bus.emitNamed("temperature", 21.5);          // -> logs: temperature 21.5
-
-const sig = createSignal("temperature", 21.5); // a product Signal
-sig.toEnvelope();                               // portable across hub/relay
-```
-
-- `PROTOCOL` — the product wire tag (`"signal/1"`) stamped on every signal.
-- `class Signal` — one published signal: `{ name, value, protocol, meta }`.
-- `createSignal(name, value, meta?)` — factory for a `Signal`.
-- `class Bus` — `on(name, fn)`, `off(name, fn)`, `emit(signal)`,
-  `emitNamed(name, value, meta?)`, `listenerCount(name)`.
-
-## CLI
-
-```sh
-signal emit greeting "hello"     # emit a named product signal and print it
-signal serve ready done          # tiny in-proc signal server, emits then exits
-signal help
-```
-

-from: morgan
-subject: "rename our `signal` product to `beacon` across the stack"
-priority: high
----
-We're renaming our product from `signal` to `beacon`. It ripples across the whole stack — please coordinate it:
-
-- **signal** (base): the npm package `@acme/signal` → `@acme/beacon`, the `signal` CLI bin → `beacon`, the wire
-  protocol tag `signal/1` → `beacon/1`, README/docs, internal product references.
-- **signal-relay** (consumer): the `@acme/signal` peerDependency + imports/product references, the address scheme, docs.
-- **signal-hub** (consumer): the product references + the `signal://` resource scheme → `beacon://`.
-- **config**: `app.toml` (the product config — that one's yours).
-
-**CRITICAL:** `signal` also names a primitive — the OS signal and `AbortSignal`/`controller.signal`/`SIGTERM`. Do
-**not** rename the primitive, only the product. A blind find-replace will break things.
-
-Keep every repo's test suite green (`node --test`). **Sequence** the cutover so consumers never reference a name
-the base no longer provides — rename the base first, and a backward-compat/alias window is fine DURING the cutover
-(have the base export both names briefly), mirroring a dual-honor cutover. **But the alias window is a TEMPORARY
-migration tool: once every consumer has migrated, CLOSE it fully — the FINAL state must be a clean cutover with
-ZERO product `signal` left anywhere** (drop any legacy `@acme/signal` export, `signal/1` protocol, `signal://`
-scheme, and legacy-named tests/comments; keep only the runtime primitive). A lingering product `signal` token —
-even in a comment or a retained legacy alias — means the rename isn't finished. Each of you touches only the repo you own; coordinate
-everything else by message.
-
-When it's done, tell me how you decomposed + sequenced it, and any problems you hit.

-This eval tests whether a Codex team writes regression tests instead of coverage theater.

-The developer can change tests only. The supervisor owns no product repository.

-A held-out battery plants 12 mutations. The added suite must kill at least 10 mutations.

-
-This sample hook safeguards topic branches that have been
-published from being rewound.
-
-The workflow assumed here is:
-
- * Once a topic branch forks from "master", "master" is never
-   merged into it again (either directly or indirectly).
-
- * Once a topic branch is fully cooked and merged into "master",
-   it is deleted.  If you need to build on top of it to correct
-   earlier mistakes, a new topic branch is created by forking at
-   the tip of the "master".  This is not strictly necessary, but
-   it makes it easier to keep your history simple.
-
- * Whenever you need to test or publish your changes to topic
-   branches, merge them into "next" branch.
-
-The script, being an example, hardcodes the publish branch name
-to be "next", but it is trivial to make it configurable via
-$GIT_DIR/config mechanism.
-
-With this workflow, you would want to know:
-
-(1) ... if a topic branch has ever been merged to "next".  Young
-    topic branches can have stupid mistakes you would rather
-    clean up before publishing, and things that have not been
-    merged into other branches can be easily rebased without
-    affecting other people.  But once it is published, you would
-    not want to rewind it.
-
-(2) ... if a topic branch has been fully merged to "master".
-    Then you can delete it.  More importantly, you should not
-    build on top of it -- other people may already want to
-    change things related to the topic as patches against your
-    "master", so if you need further changes, it is better to
-    fork the topic (perhaps with the same name) afresh from the
-    tip of "master".
-
-Let's look at this example:
-
-		   o---o---o---o---o---o---o---o---o---o "next"
-		  /       /           /           /
-		 /   a---a---b A     /           /
-		/   /               /           /
-	       /   /   c---c---c---c B         /
-	      /   /   /             \         /
-	     /   /   /   b---b C     \       /
-	    /   /   /   /             \     /
-    ---o---o---o---o---o---o---o---o---o---o---o "master"
-
-
-A, B and C are topic branches.
-
- * A has one fix since it was merged up to "next".
-
- * B has finished.  It has been fully merged up to "master" and "next",
-   and is ready to be deleted.
-
- * C has not merged to "next" at all.
-
-We would want to allow C to be rebased, refuse A, and encourage
-B to be deleted.
-
-To compute (1):
-
-	git rev-list ^master ^topic next
-	git rev-list ^master        next
-
-	if these match, topic has not merged in next at all.
-
-To compute (2):
-
-	git rev-list master..topic
-
-	if this is empty, it is fully merged to "master".

-# An example hook script to update a checked-out tree on a git push.
-#
-# This hook is invoked by git-receive-pack(1) when it reacts to git
-# push and updates reference(s) in its repository, and when the push
-# tries to update the branch that is currently checked out and the
-# receive.denyCurrentBranch configuration variable is set to
-# updateInstead.
-#
-# By default, such a push is refused if the working tree and the index
-# of the remote repository has any difference from the currently
-# checked out commit; when both the working tree and the index match
-# the current commit, they are updated to match the newly pushed tip
-# of the branch. This hook is to be used to override the default
-# behaviour; however the code below reimplements the default behaviour
-# as a starting point for convenient modification.
-#
-# The hook receives the commit with which the tip of the current
-# branch is going to be updated:
-commit=$1
-
-# It can exit with a non-zero status to refuse the push (when it does
-# so, it must not modify the index or the working tree).
-die () {
-	echo >&2 "$*"
-	exit 1
-}
-
-# Or it can make any necessary changes to the working tree and to the
-# index to bring them to the desired state when the tip of the current
-# branch is updated to the new commit, and exit with a zero status.
-#
-# For example, the hook can simply run git read-tree -u -m HEAD "$1"
-# in order to emulate git fetch that is run in the reverse direction
-# with git push, as the two-tree form of git read-tree -u -m is
-# essentially the same as git switch or git checkout that switches
-# branches while keeping the local changes in the working tree that do
-# not interfere with the difference between the branches.
-
-# The below is a more-or-less exact translation to shell of the C code
-# for the default behaviour for git's push-to-checkout hook defined in
-# the push_to_deploy() function in builtin/receive-pack.c.
-#
-# Note that the hook will be executed from the repository directory,
-# not from the working tree, so if you want to perform operations on
-# the working tree, you will have to adapt your code accordingly, e.g.
-# by adding "cd .." or using relative paths.

-# Weird Git Setup eval for st2
-
-This eval starts one Codex agent inside a linked Git worktree.
-
-The agent must discover the checkout shape, fix a failing test, and commit on `feature`.
-
-The held-out judges reject a change on `main`, a dirty sibling worktree, or a removed regression test.
-
-Run it with `st2 eval ./evals/st2/weird-git-setup`.
-
-The source fixture came from `compoundingtech/evals` commit `3db48ab56d40ce27dfd94f89d2db9b692d93836a`.

-# Canonical native agent declarations
-
-These maintained, hand-authored declarations are the canonical starting points:
-
-- [`agent-claude.kdl`](agent-claude.kdl) uses Claude Code's rules loader and
-  native `SessionStart`, `PreCompact`, and `StopFailure` hooks.
-- [`agent-codex.kdl`](agent-codex.kdl) composes the persona and bus contract
-  into `AGENTS.md` and uses Codex's native `SessionStart`, `PreCompact`, and
-  `Stop` hooks.
-- [`agent-pi.kdl`](agent-pi.kdl) composes the persona and bus contract into
-  `AGENTS.md` and delivers natively. pi has no hook mechanism of its own: st2
-  injects a channel extension from the same immutable set, so this declaration
-  declares no `ding` and renders nothing for delivery.
-
-The examples use `<host>`, `<identity>`, and `<workspace>` placeholders. st2 provides `CATALOG`,
-`ST_ROOT`, `PTY_ROOT`, and `ST_HOOKS` when it starts a task, so hook declarations contain no
-machine-specific install paths. Copy the appropriate file outside the catalog, replace every
-placeholder, assemble it and the referenced files under the publication bundle's `assets/`
-directory, then publish the bundle. `role` is optional metadata; `supervisor` is optional runtime routing.
-Uncomment them when the seat has an assigned role or reports to another bus identity.
-
-## Lifecycle
-
-st2 accepts exact canonical KDL or a create-only bundle; it does not compile human intent. Inspect
-all KDL and workspace targets before publication.
-
-Use this sequence:
-
-```sh
-st2 hooks install
-st2 hooks verify
-input_sha256="$(st2 agent digest --bundle <bundle>)"
-st2 agent publish --catalog <catalog> --bundle <bundle> \
-  --input-sha256 "$input_sha256" --expect-absent --json
-st2 validate <catalog>
-st2 up <catalog> --host <host> --materialize-only
-st2 up <catalog> --host <host> --once
-```
-
-Hook installation is explicit and receipt-bearing. `up` and materialization only verify the
-selected immutable hook set; they never refresh shared scripts. Managed settings resolve
-`$ST_HOOKS/<script>` into that versioned set.
-
-## Status discipline
-
-All three maintained declarations load the shipped bus contract. Agents must declare `busy` before
-actively executing a unit of work and return to `available` only when yielding or ready for new
-work. Busy agents still receive DING. `dnd` is the only delivery hold and the sidecar does not renew
-it, so an abandoned hold becomes stale after 15 minutes. st2 intentionally does not inspect any
-harness's terminal pixels.
-
-A pi seat never enters the DING path at all — a declaration carrying both `ding` and `deliver` is
-refused — so its delivery rests on `pi.sendUserMessage()` and pi's own idle proof rather than on a
-composer heuristic.
-
-The `render { ... }` block is ordered. `copy`, `file`, `json-upsert`, and `ensure-line` are
-boot-gating operations; a failure prevents that agent from starting. Materialization refuses any
-content or mode change to a Git-tracked target before its first workspace write. A byte-identical
-tracked target with the declared mode is safe and idempotent. Untracked and non-Git targets remain
-writable. `git-exclude` is advisory, so a non-Git workspace or exclusion failure does not prevent a
-boot.
-
-Each content directive accepts `executable=#true`. The property selects exact mode `0755`; its
-absence or false value selects exact mode `0644`. Materialization corrects mode drift even when the
-bytes already match. A `copy` source mode does not affect the destination mode. An unchanged
-operation is not reported as materialized.
-
-Tracked-target detection invokes `git` and fails closed if it cannot inspect a workspace that appears
-to belong to a Git worktree.
-
-Materialization is idempotent. JSON values are deep-merged, existing unrelated
-settings survive, loader lines are added once, and generated workspace files
-are excluded without changing the repository's committed `.gitignore`.

-// Canonical hand-authored declaration for a pi agent.

-// Copy st2's shipped `templates/bus.st2.md` into the publication bundle as `assets/bus.st2.md`.
-// pi discovers `AGENTS.md` from the workspace natively, and the boot ritual st2 restores at session
-// start is a pointer into that contract, not a standalone instruction — it says to set status and
-// drain the inbox without naming the commands that do either.
-//
-// The contract alone is enough; no operator-composed persona is required. Measured twice against a
-// live model, independently (`docs/vrs/.experiments/2026-08-18-pi-captures/run-h-live-provider.txt`,
-// sections 6 and 7): with the contract copied verbatim, the agent set its status and drained its
-// inbox on the first tool call, using the documented commands and without exploring the filesystem.
-// Without it, the same prompt sent the agent hunting with `find /`, and it never set its status.
-//
-// To add a persona, put it in front of the contract in the same file — pi loads `AGENTS.md` or
-// `CLAUDE.md` once per directory, so the workspace has exactly one slot.
-//
-// Unlike the Codex and Claude examples this one declares no `ding`: pi delivers natively. st2 hands
-// each message to the live session through the channel extension it injects from its own verified
-// hook set, so there is no screen inspection on the delivery path and nothing to render for it.
-// `st2 hooks install` must have been run, exactly as for the other harnesses' lifecycle scripts.

 Only Claude, Codex and OMP report subagents: `@fractal/client` exports that observing set as `SUBAGENT_OBSERVING_DRIVERS` and classifies each agent's wire driver with `classifySubagentDriver` (observing, OpenCode/Pi non-observing, or unknown/absent). OpenCode and Pi do not report them: `pi_channel` forwards subagent frames only for OMP, not Pi. An explicit roster, including an empty one, is always reported (zero paints no chip), and a stale reported roster stays reported. When the roster is omitted, the live projection derives the cause from the driver and lifecycle: an observing agent that is desired or starting has not sent its first report yet, so its observation is unavailable and its "?" reads **Not reported yet**; a running observing agent's daemon is too old to send the field, **Not reported by this daemon version**; OpenCode/Pi and any unknown or absent driver conservatively read **Not reported by this harness**, never an inferred daemon fault. Child rows always read **Not reported by this harness**, because the child wire shape carries no nested report. Both not-reported states omit the chip and expose the exact cause in Details and the row description. Views consume the projected observation and reason, never harness-name comparisons; the deep-tree count story is layout stress only, not live nested reports.
 
+`SidebarTabs` presents peer sidebar views with React Aria arrow-key navigation. Its single leading status slot shows an open question before needs-you, attaches counts only above one, and drops counts before labels at narrow widths. The host owns gateway-scoped selection persistence and supplies only available destinations; the web app currently exposes Agents, with `g a` to open it and `?` for shortcut help. Agent rows retain their activity glyph and a separate trailing question or needs-you diamond.
+
+The decorative glyph and attached count are painted separately from the tab's text label; the accessible name spells out their meaning. Tabs use equal tracks, include a 44px touch minimum in count fitting, and keep their label positions stable as attention changes.
+
 `AgentThreadTabs` presents Subagents above the conversation only when an addressable child exists; a parent-only conversation has no strip. Pass `threads`, `selectedId`, `onSelectionChange`, and the selected conversation as children; its ref exposes `focusSelected()` for the sidebar count. Arrow keys select peer tabs. A ResizeObserver measures intrinsic tab widths against the available strip width: tabs that do not fit move to the Subagent threads drawer, while the selected tab always remains visible. The drawer groups Main and Subagents rather than repeating a read-only tag on every child. Read-only children have a bottom notice in the composer position and a Main button to return to the parent; the host must omit child composer and mutation controls. The live web app uses only task-block `SubagentSummary.conversation.session_id` references for OMP child tabs, never roster session IDs or raw task IDs as labels. The parent remains mounted while browsing a child, preserving its draft. Sidebar counts describe running children; tabs describe addressable children in the loaded transcript window.
 
 When the narrow thread drawer covers the conversation, the retained conversation panel is inert: neither its composer nor transcript controls participate in keyboard traversal. Closing the drawer restores interaction; the wide side-by-side drawer leaves the conversation interactive.

While the daemon is still indexing held mail, message-delivery says it did not count late mail. Mail to a seat whose host keeps its receipts is still read from that host, and mail that host does not answer for is still reported as unknown, never as late. One change: when a host has more late mail than one read asks of it, its seats are counted from this member's own state, as held-mail does, rather than reported as unknown past the bound.

-//! Constrained, source-preserving authoring of Agent Spec presentation and desired state.
-//!
-//! Presentation is declaration state, not runtime identity. Every edit holds the shared persistent
-//! catalog-authoring lock, rechecks the original bytes, and atomically replaces exactly one
-//! canonical KDL declaration. TOML, JSON, and callers outside the supplied actor relationship fail
-//! closed. A declaration marked `meta { managed-by "nix" }` fails closed too, except on the
-//! lifecycle verb, where the projection may assert that marker and author the one transition its
-//! own source can no longer express (#473). `ST_AGENT` is a trusted-fleet guardrail rather than
-//! authentication. The lock serializes cooperating local st2 writers; it is not a cross-host lock.

-//! `st2 service install|render-unit|status|uninstall` — manage or render `st2 up` as a
-//! **systemd-user** unit so the supervisor comes back on boot and on crash.
-//!
-//! **Lifecycle commands are Linux-only, by design (the maintainer).** The Mac stays MANUAL — the
-//! maintainer runs `st2 up` themselves there (TCC: a launchd-owned process can't inherit their
-//! GUI/keychain trust), so we deliberately do NOT ship a launchd path. Read-only rendering works
-//! anywhere because it performs no service-manager operation.
-//!
-//! A service restart is safe because st2 spawns each task in its own transient scope
-//! (`systemd-run --user --scope`, see `isolate.rs`) —
-//! a SIBLING of this unit, not a child. So stopping/restarting `st2.service` reaps only the
-//! supervisor loop; the agents survive in their scopes and a fresh supervisor ADOPTS them
-//! (tests/nomad_survival.rs + tests/transport_isolation.rs). That is the whole reason this unit is
-//! now a safe thing to install.

-//! `st2 agent address` — the mutable agent address (R24/R25) as one atomic address-book cutover.
-//!
-//! Address is the third authoring sibling of `st2 rename` and `st2 describe`: it holds the same
-//! catalog-authoring lock, resolves exactly one declaration, applies the same `ST_AGENT`
-//! self/descendant guardrail, refuses Nix-owned declarations and non-KDL formats, and never
-//! touches the subject's immutable `id`. What it adds is host-local address uniqueness, decided
-//! against the complete prospective catalog rather than the one declaration being edited.

-//! The Claude status-line tee, exercised as Claude runs it: `hooks/claude-statusline.sh` as the

-//! These assert the tee's exact stdout bytes rather than the record it happens to write, because
-//! the failure HC-R18 names is invisible from the record's side. Claude's `statusLine` is a single
-//! slot whose winning declaration replaces the others outright — measured against 2.1.250,
-//! `.claude/settings.local.json` (the file st2 materializes) beats both `.claude/settings.json` and
-//! `~/.claude/settings.json`, and the losing command never runs. So a tee that records perfectly
-//! and forgets to chain leaves every managed agent with a blank status line, and a test that only
-//! checked the record would be green throughout.
-//!
-//! Stdout is the renderer's channel and nothing else may reach it. The renderer's bytes, or no
-//! bytes: a warning, a diagnostic, or the raw payload written there interleaves with the
-//! operator's line, which is why the assertions are on exact bytes and not on substrings. The
-//! degraded arms therefore assert stdout is EMPTY and take their positive evidence from stderr,

-//! P3+P4 end-to-end (the benign internal-proof milestone): `st2 eval <folder>` runs a whole eval
-//! folder → VERDICT through the real binary. Benign shell "agents" choreograph the real flow on the
-//! FLAT eval bus via `st2 message` (exercising the flat-bus bridge): kick → worker→sup report →
-//! sup→requester confirmation (post-dating the report), then the judge engine grades the deliverable.
-//! No real harness; st2 eval mints its own hermetic catalog + PTY_ROOT (never touches the live fleet).
-//!
-//! Needs `pty` on PATH — HARD failure if absent unless ST2_ALLOW_PTY_SKIP is set.

-//! The supervisor-decoupling gate.
-//!
-//! st2 is a *decoupled* supervisor: stopping or crashing the runner MUST leave its running tasks
-//! alive, and a fresh runner MUST ADOPT them rather than cold-booting. The ONLY thing that kills a
-//! task is an explicit teardown (a `retired` spec). This guarantee is proven with real processes —
-//! installing the real `st2` binary, stopping it with SIGTERM *and* SIGKILL, atomically replacing
-//! that binary, and asserting the task pids and creation identities survive and get re-adopted
-//! without duplicate boots — not with a fake runner.
-//!
-//! Two spawn paths, both covered:
-//!   - `exec` — st2 supervises the process directly and detaches it with `setsid`, so it survives
-//!     st2's death (this is st2's OWN code providing the property).
-//!   - `pty`  — st2 shells out to the `pty` daemon, which owns the session independently of st2.
-//!
-//! Isolation: every fixture points `$XDG_STATE_HOME` (exec pids) and `$PTY_ROOT` (pty sessions) at its
-//! own temp dirs and uses a throwaway host, so these tests can NEVER touch the live fleet's sessions.
-//! Tasks are `sleep 120` — long enough for the test, short enough to self-reap if cleanup is ever
-//! skipped; the fixture's `Drop` also force-kills anything it spawned, even on a panic.

-//! #204 against the real binaries and real processes: a fail-mode task crash-loops into a terminal
-//! park, `st2 tasks` reports the fault, `st2 unpark` clears exactly that task, and a healthy peer
-//! keeps the same pid and generation throughout.
-//!
-//! `tests/run.rs` proves the same recovery deterministically against a fake runner, which is the
-//! CI-gated proof. This one exists for the claim that a fake runner structurally cannot make: that
-//! *no supervisor-wide restart occurred*. A pid and a process generation that survive the whole
-//! episode are the only direct evidence of that, and they require real processes.
-//!
-//! Note that `st2 up --once` cannot appear here. Both single-pass entry points build a fresh
-//! `FlappingCap`, so a one-shot reconcile can never park anything; the park is a property of a
-//! long-running supervisor, and this test drives a real one.
-//!
-//! Every wait is on an observed condition with a deadline, never a fixed sleep standing in for one.
-//! `XDG_STATE_HOME` is a temp dir, so nothing here can read or clear a real host's parks.

-//! The transport-decoupling gate — the permanent fix for the fleet-fragility incident.
-//!
-//! st2's `nomad_survival` gate proves a task survives its supervisor's *process* death (SIGTERM/
-//! SIGKILL to st2). That is necessary but not sufficient: on a systemd host a supervisor and its
-//! children can share one service cgroup, and `setsid` changes a
-//! process's *session*, not its *cgroup*. systemd tears a unit down by **cgroup**, so a
-//! `systemctl restart` of the transport/supervisor unit SIGTERM+SIGKILLs every task still sitting in
-//! that cgroup — which is exactly how a fabric restart cascade-killed the whole example-linux fleet.
-//!
-//! This gate proves the fix: st2 spawns each task into its OWN transient systemd scope (own cgroup, a
-//! SIBLING of the transport unit), so a cgroup-cascade kill of the transport unit cannot reach it. It
-//! is proven with REAL processes — the real `st2` binary running *inside* a stand-in transport scope,
-//! a real `systemctl --user stop` of that scope, and assertions on real pids — not a fake runner.
-//!
-//! The CONTROL makes the gate honest: the same cascade that must leave the isolated task ALIVE must
-//! also leave the supervisor (which lives *in* the transport scope) DEAD. If the supervisor survived,
-//! the "stop" did nothing and the survival assertion would be hollow.
-//!
-//! Isolation: the fixture points `$XDG_STATE_HOME` (exec pids) and `$PTY_ROOT` at its own temp dirs
-//! and uses a throwaway host, and every scope it creates is uniquely named and torn down on `Drop`
-//! (even on panic), so this can never touch the live fleet.
-//!
-//! Linux-only: the mechanism under test is a systemd `--user` scope. The macOS realization (setsid +
-//! reparent, no cgroups) is proven in `tests/transport_isolation_macos.rs`.

-//! The transport-decoupling gate — macOS realization.
-//!
-//! macOS has no cgroups, and launchd does NOT cascade-kill detached children (proven in the incident:
-//! the Mac fleet survived the Mac fabric restart while the systemd fleet died). So on macOS the whole
-//! defense is `setsid` + reparent to launchd/init — st2's [`isolate`](fractal_legacy_runner::isolate) primitive runs in
-//! `Detached` mode (a pass-through; the exec backend's `setsid` provides the detachment).
-//!
-//! The failure mode this rules out on macOS is a **process-group** signal: if a task stayed in the
-//! spawner's process group, a group-directed kill of the spawner (or its group) would take the task
-//! too. `setsid` puts the task in its own session and group, so it does not. This gate proves it with
-//! real processes — a real `st2 up` in its own process group, a real `kill -KILL -<pgid>` of that
-//! group, and assertions on real pids.
-//!
-//! The CONTROL keeps it honest: the same group kill that must leave the task ALIVE must leave the
-//! spawner (which IS in the killed group) DEAD — otherwise the kill did nothing and survival is hollow.
-//!
-//! Linux's systemd-scope realization lives in `tests/transport_isolation.rs`.
