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 "" { - host "" - workspace "" - lifecycle "adopt-only" - argv "codex" "" -} -``` - -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 agent desired-state suspended \ - --reason "Waiting for capacity" -st2 --catalog agent desired-state running -st2 --catalog agent desired-state 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 "Release worker" -st2 describe "Owns release preparation and verification." -st2 rename --clear -st2 resource add --uri --reason "" -st2 resource remove -st2 resource rename -``` - -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 `/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 "" { - // 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 --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 ` to validate another machine's local paths. Supervisors may be declared as either a -bare identity or the fully-qualified `.` 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 "$CATALOG" --host -st2 service status -``` - -Each task runs in its own transient scope, so restarting the supervisor does not kill live agents. - -On macOS, use a manual one-shot reconcile: - -```sh -st2 up --catalog "$CATALOG" --host --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 "$CATALOG" --host --once --task -``` - -Unknown, ambiguous, and wrong-host task selectors refuse before workspace writes or PTY inspection. -A selected generated DING that is dead or absent is reported as `held`, because starting its -canonical agent would broaden the exact-task operation. Explicit sibling tasks remain independently -selectable. - -`st2 doctor` accepts the absence of a live host lock as the normal manual/`--once` mode. For a -resident `st2 up` deployment, use `st2 doctor --require-supervisor` to make a missing loop fail the -health check. A stale lock left by a dead supervisor is always a failure. The underlying -non-interactive `pty list --json` runtime probe is bounded; a wedged client becomes an explicit -doctor failure instead of hanging the health check. Its short outer deadline is containment for a -wedged runtime, not a fleet-scalability mechanism. - -For a foreground supervisor on any host: - -```sh -st2 up --catalog "$CATALOG" --host -``` - -### Typed task inventory (diagnostic only) - -Use the typed inventory instead of parsing `doctor` prose: - -```sh -st2 tasks --catalog "$CATALOG" --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//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 --subject "work" -m "Please handle the scoped task." -st2 message ls -st2 message read -st2 message reply -m "Handled." -st2 message archive -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 .` 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 `/status`, while unread messages, archive receipts, and context -live under `/resources/`. The flat `/` 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 --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 -// /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 --json - -st2 request reply \ - --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:] (from ); 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 ` 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 -``` - -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 ` 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 ` 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.

Ownership is persisted before the transport call, so a crash between attempt and evidence reopens as an ambiguous attempt that holds instead of re-sending. 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` | -| **Idempotent service requests** | A declared non-agent service principal publishes one exact JSON request per caller-supplied idempotency key to a canonical Agent Spec inbox.

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.

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.

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.

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.

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.

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 `/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. - -## Evidence and Argument - -The comparison is recorded in -[`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:///` to -`/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. diff --git a/docs/vrs/.decisions/0011-the-linked-record-plane-is-retired.md b/docs/vrs/.decisions/0011-the-linked-record-plane-is-retired.md deleted file mode 100644 index 9cdb397f72b..00000000000 --- a/docs/vrs/.decisions/0011-the-linked-record-plane-is-retired.md +++ /dev/null @@ -1,98 +0,0 @@ -# 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)).

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 `/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** `/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 `/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. diff --git a/docs/vrs/.decisions/0014-resource-profiles-are-state-first-read-and-observe-capabilities.md b/docs/vrs/.decisions/0014-resource-profiles-are-state-first-read-and-observe-capabilities.md deleted file mode 100644 index cd3a7e3a41c..00000000000 --- a/docs/vrs/.decisions/0014-resource-profiles-are-state-first-read-and-observe-capabilities.md +++ /dev/null @@ -1,136 +0,0 @@ -# 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.

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//_.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.

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).

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.

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. - -## Delivery - -```text -prove empty ─► record ownership ─► paste ─► two exact-safe observations - │ - ├─ current unread fence ─► Return ─► receipt - ├─ archive/read/close ────────────► Cancelled - └─ failure or ambiguity ──────────► Staged - -receipt ─┬─ Accepted ──────────────────────────────────────────────► Delivered - └─ RetainedSafe / RetainedBlocked / NotRetained / Unproven ► Staged - -staged retry ─► receipt ─┬─ Accepted ──────────────────────────────► Delivered - ├─ RetainedSafe ─► final receipt ─┬─ Accepted ─► Delivered - │ ├─ RetainedSafe ─► Return ─► receipt - │ └─ other ────────► Staged - ├─ archived/read/closed before Return ────► Cancelled - ├─ NotRetained + unread ──────────────────► Staged - └─ RetainedBlocked / Unproven ─────────────► Staged -``` - -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). diff --git a/docs/vrs/02-agent-spec/requirements.md b/docs/vrs/02-agent-spec/requirements.md deleted file mode 100644 index ae132188c0d..00000000000 --- a/docs/vrs/02-agent-spec/requirements.md +++ /dev/null @@ -1,150 +0,0 @@ -# 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.

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.

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.

Retirement preserves the agent ID, removes the subject from -ordinary address routing, and releases its effective address after the retired -catalog generation becomes visible.

Keep last-known-good ownership -and perform no destructive action to that work. Independent agents, tasks, and -files can continue when their input and ownership proof are complete. - -Authoring: [pinned validation, health, and lifecycle][evals-lifecycle]. st2 -source: [`RawSpec` and `AgentSpec`](../../../crates/agent-spec/src/spec.rs). -Evidence: [validation](../../../src/validate.rs) and -[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 [--reason ...] -[--managed-by ]`. 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. - -st2 source: [`AgentDesiredState`](../../../crates/agent-spec/src/spec.rs), -[KDL lowering](../../../crates/agent-spec/src/kdl_format.rs), -[authoring](../../../src/agent_author.rs), and -[reconciliation](../../../src/reconcile.rs).

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), -[KDL lowering](../../../crates/agent-spec/src/kdl_format.rs), and -[`residency`](../../../src/residency.rs).

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 --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.

Names -are 1..=40 lowercase alphanumeric characters with optional interior hyphens -and cannot collide with an authored task named -`stream-`. 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-` with -default runtime ID `.stream-`. 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. - -Authoring: canonical Agent Spec stream field after the matching evals change -lands. st2 source: [`Stream`](../../../crates/agent-spec/src/spec.rs), -[KDL lowering](../../../crates/agent-spec/src/kdl_format.rs), and -[reconciliation](../../../src/reconcile.rs).

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 (--clear |
)`. 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. - -Authoring: canonical Agent Spec address after the matching evals change lands. -st2 source: future `AgentSpec::address`, address-book resolution, and -`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.

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.

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.

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`.

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.

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.

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 -`.` 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///agent.kdl` | persona, tasks, presence, roster row, DING sidecar, doctor obligations, supervisor edges | — | -| `service` | `principals///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/.json` → `sent/keys/.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/.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 ` — 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 ` 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.

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///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. - ---- - -## 10.

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///principal.kdl` | `resources/request-state/outgoing/` | `?` | -| 3 | Eval external requester | `message::ExternalInbox` (MESSAGE-A01 compat) | none | `?` | -| 4 | The runner, as `st2.` | `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///principal.kdl` | -| present | st2 supervises one long-running exec task `.` 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///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.` 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 `-.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///resources/ - inbox/.md replies from agents (ordinary messages) - archive/.md - events/.json - events/.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 --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 --json` | `st2 message read ` (and `--json`) | -| `st2 request reply --json …` | `st2 message reply ` | -| `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.

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.`, 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///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 ` 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.` 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///principal.kdl` | Fresh namespace `sources///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 --event-id ` 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 - `-` 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.` 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.

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///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?

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:` 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::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::sha:` 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` 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.` (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.

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 `./` `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.

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 | -| --- | --- | ---: | --- | ---: | ---: | --- | --- | -| CI transitions | Not measured | — | — | — | — | — | — | -| Builds | Not measured | — | — | — | — | — | — | -| Timer sources | Not measured | — | — | — | — | — | — | - -These rows are an empty reporting template, not measurement results.

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 ` 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 [--command | -- [...]] -st2 stream rm -``` - -The launch forms are mutually exclusive.

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.

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).

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.

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:` | -| 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//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. - -## Native driver diagnostic snapshot (OHS-R11–OHS-R16) - -```text -launch -> version gate -> API gate -> SSE -> seed -> provider auth -> delivery -> read-back - \______________ typed failure/recovery transitions ______________/ - | - v - /driver-diagnostic - st2.driver-diagnostic.v1 - | - +--------------+---------------+ - v v - agents --json.driverDiagnostic Doctor advisory -``` - -The native driver core, not OpenCode prose and not either consumer, owns the -closed model.

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()` 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 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.

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()`; `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()` or `missing`. Present→missing emits a -canonical tombstone whose body contains `old: ` 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:::::` -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.

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. - -## Evidence - -The closed resolver mechanism and sandbox bounds are supported by the -[plugin-boundary comparison](./.experiments/2026-08-26-plugin-boundary-comparison.md). -Composition against the real Nix-generated standing-seat shape is supported by -the [real-shape end-to-end experiment](./.experiments/2026-08-26-dotfiles-real-shape-e2e.md). -The state-first attention boundary and minimal catch-up state are supported by -the [GitHub attention-filter](./.experiments/2026-08-29-github-attention-filter-prototype.md) -and [lifecycle state-space](./.experiments/2026-08-29-smart-resource-lifecycle-prototype.md) -prototypes.

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.

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=→` 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 - -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 -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` 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///pull/`. 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///issues/` 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 = · [] -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.

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".

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.

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.

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.

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 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, `/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. diff --git a/docs/vrs/08-harness-context/roadmap.md b/docs/vrs/08-harness-context/roadmap.md deleted file mode 100644 index fd9b8ca1970..00000000000 --- a/docs/vrs/08-harness-context/roadmap.md +++ /dev/null @@ -1,86 +0,0 @@ -# Harness context roadmap - -Non-normative.

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 `/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)): - -```json -{ - "schema": "st2.harness-context.v1", - "agent": "", - "harness": "claude | codex | pi | omp | opencode", - "usedTokens": 92283, - "windowTokens": 258400, - "usedPercent": 33, - "model": null, - "costUsd": null, - "sessionTotalTokens": 2235329, - "rateLimits": { "fiveHour": 31, "sevenDay": 55 }, - "compactions": 3, - "lastCompactionMs": 1788000097290, - "lastCompactionTrigger": "manual | auto | threshold | overflow | idle | unknown", - "incarnation": "", - "observedAtMs": 1788000100000, - "writtenAtMs": 1788000100000 -} -``` - -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 - | since the last written reading? -> write - +-- proven Claude account-window exhaustion changed? -> write - +-- record older than HARNESS_CONTEXT_HEARTBEAT? -> write - +-- 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 `/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:** `/.st2/harness-context-staging`, derived only from the - exact canonical `/agents//` 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 `/agents/` and could leave - `.harness-context.tmp--` 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(/resources/inbox)` or the exact path -`/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.

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) - -The only producer that needs two sources: the numerator is pushed on the SSE -stream and the denominator is pulled from the config surface. Both traps here -are measured and both silently produce a wrong number: - -- **`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.

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.

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//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 `.
`. 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 ``. Any - long-form named task without an explicit task ID defaults to - `.`, 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//direct.omp.` 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. diff --git a/docs/vrs/spec.md b/docs/vrs/spec.md deleted file mode 100644 index 885b20fee71..00000000000 --- a/docs/vrs/spec.md +++ /dev/null @@ -1,1925 +0,0 @@ -# st2 specification - -This document specifies st2's current implementation contract.

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.

Neither -field participates in identity, address resolution, authorization, durable -paths, or lifecycle. The Agent Spec declaration is their sole source of truth. -`/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 - `/.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 ` request. Compact agent lowering assigns its -canonical task the explicit runtime ID ``. Every long-form named task -without an explicit task ID defaults to `.`, 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.actor.address=`, and optional -`agent.presentation.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///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 `/.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 `/.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///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///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", - "beforeRootSha256": "", - "afterRootSha256": "", - "paths": [ - { - "path": "agents/host/worker/agent.kdl", - "kind": "modified", - "before": { "class": "agent-spec", "executable": false }, - "after": { "class": "agent-spec", "executable": false } - } - ], - "agents": [ - { - "host": "host", - "identity": "worker", - "kind": "modified", - "fields": [ - { - "address": "/agents/host/worker/tasks/pty/agent/argv/0", - "before": { "state": "present", "type": "string" }, - "after": { "state": "present", "type": "string" } - } - ] - } - ] -} -``` - -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. - -`/.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-","expectedRootSha256":"","preparedRootSha256":"","originalPaths":["", "..."]} -``` - -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 `.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 --resume -- `. -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 ` and -`--residency-warm-capacity `. 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 ` 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. - -## Host-local scheduling and supervision - -```text -hand-authored KDL - │ - ▼ -validate ──► materialize ──► host-local st2 scheduler/reconciler - │ - ┌────────┴────────┐ - ▼ ▼ - PTY / exec DING sidecar - │ │ - └──── state + bus ┘ - ▲ - │ - one intelligent root agent - observes · recovers · escalates -``` - -- **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.

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.

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 `.`, 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= "--description=st seat" --expand-environment=no -- ... - ``` - - 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. `` and every `` are appended as their - original OS strings, without shell rendering, dollar escaping, or - environment substitution. Detached and degraded-detached modes remain - ` ...` 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 ` 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//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::` 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 `/.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 ` 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. - `/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=.direct.omp.` from `PTY_SESSION`, and writers -create `agents//direct.omp./` 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//`, 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//` into the catalog control plane at -`.st2/archive//`, 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 due retired -seats and deferred 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//direct.omp. - 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 due dead direct actors and deferred - to the next pass`; the next pass resumes after the last actor examined. -3. A due actor whose `.st2/archive//` 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//` - plus a tombstone whose `reason` is - `direct OMP actor: PTY session 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.

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 `/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 ` 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 ` resolves one exact local -task before writing and renders only its owning agent. `st2 up --once --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 ` 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.
