+bounded app-server integration and qualified delivery observation. It preserves
+ordinary opt-out results. Native observation is qualified only for the recorded
+macOS arm64 Codex versions/topology; explicit operator confirmation is separate

+2. Fresh authenticated reads verify ownership, pending stages, stage-only Trusted
+   Publisher mapping, package publish-MFA and protected GitHub npm environment.
+   Any unread gate needs a current explicit user exception; no protections change.
+3. Validate exact-source reproducible packing, isolated version/install/removal,
+   skill metadata defaults and every packaged Markdown file under the
+   [documentation gate](#documentation-gate-for-the-next-release).
+4. Obtain separate approval naming the exact merged 40-character main SHA,
+   `session-peer@0.4.0`, `stable-stage` and eventual latest promotion to 0.4.0.
+5. Dispatch only the approved source/version/mode; review retained Actions bytes

+Both SSH endpoints require exactly 0.4.0. The published skill 0.2.1 pin remains

+TS source/package 0.4.0 preserves the three reviewed profiles accepted by public 0.3.6 (skill 0.1.0, 0.2.0 and published 0.2.1) and adds exactly `0.3.0 / typescript / min 0.1.0 / full 0.4.0 / probe-help` for runtime 0.4.0 only. Compiled default, explicit `undefined`, explicit 0.4.0 and outer `inspectSkill` use this finite row. All historical runtime/profile verdicts remain unchanged; old runtime identities reject the new profile, and 0.3.7, 0.4.1 and other unreviewed runtime identities remain incompatible. Parser/reader behavior and malformed/unsupported envelopes are unchanged. This is a finite row, not a SemVer range or a skill publication.

Exact-content review found no normative blocker and accepted this profile direction at design level only. The helper fixtures check exact bytes/hash, fatal UTF-8, compiled default/undefined/explicit 0.4.0 and outer inspection, with historical, future and malformed runtime rejection. The fixture is excluded from the npm package and its instructions are never executed by these checks.
+
+This is candidate-specific design/content review, not approval to install or publish the skill. The retained candidate still names its older feature checkpoint and review-only status; that source text is not evidence that its final guidance has been reviewed against the eventual published runtime. After actual supporting-runtime publication, final skill content and metadata require a fresh exact-head/whole-byte review and separate human publication approval. Runtime publication does not publish or install a skill. Existing four-language guidance retains the published 0.2.1 immutable source/hash below until a separately approved skill release is actually public; only then may a later guidance change adopt its immutable pin.

Default/undefined/outer inspection use compiled VERSION=0.3.6; an explicit 0.3.5 helper still returns its historical reviewed verdict. 0.3.7 and other unreviewed identities remain incompatible.

+# TypeScript session messaging — proposed 0.4 feature revision
+
+Preparation checkpoint (2026-10-17): this complete file is review-only data,
+not an installed/released skill or approved profile. Do not execute experimental
+operations from it. Public skill 0.2.1 and its immutable pin remain unchanged.
+Skill 0.3.0 / minimum 0.1.0 / full 0.4.0 are proposals pending exact contract/fixture review,
+actual supporting-runtime publication and separate skill release approval.
+
+## Identify the runtime and its supported commands
+
+Resolve the executable (`command -v session-peer` on POSIX, `Get-Command session-peer -All`
+in PowerShell), inspect PATH conflicts, and run that exact command with `--version`.
+Require the stable `session-peer X.Y.Z (typescript)` version marker and a runtime
+at or above this skill's declared `runtime-min-version` (current baseline `0.1.0`).
+Check this explicitly; skill metadata is not assumed to be enforced by the agent
+framework. A runtime below the minimum does not support this skill's baseline.
+Python uses that command name too: if the marker is absent, select the Python skill or ask
+which installation the user intends. Keep the resolved executable for every
+following command; do not replace another manager's launcher.
+
+Proposed revision 0.3.0 retains the ordinary 0.1.0 baseline and proposes a 0.4.0
+feature coverage reference. Neither number grants doctor compatibility, security
+currency, native/platform support or sending permission. Public 0.3.x guards do
+not accept this new tuple. A planned 0.4 row for existing profiles is not support
+for this proposal; require an explicitly reviewed finite row and exact fixtures.
+The fixed source candidate is
+[55daf83bd8ebe1cd6e67bb98259130213d1cac71](https://github.com/abruption/session-peer-ts/tree/55daf83bd8ebe1cd6e67bb98259130213d1cac71).
+It actually reports compiled VERSION 0.3.5 despite containing unshipped 0.4 work;
+a banner or help probe alone does not prove approved public source. Final integrated
+source/help, full skill bytes/profile and immutable release must be reviewed again.
+Adopt only a separately approved published skill release with recorded source/hash.
+Runtime publication does not publish/install the skill; upgrades remain user-requested
+and owned by the existing manager. Do not edit metadata to hide a rejection.
+
+Capture `--help`. If it advertises `<command> --help`, capture that command's help
+before selecting options. Older baseline help does not promise per-command
+help. A supported command or flag must appear affirmatively in supported help:
+“doctor unsupported” does not enable doctor. Version checks alone do not resolve
+unreleased builds that reuse a version string. The [published npm 0.3.4 CLI help](https://github.com/abruption/session-peer-ts/blob/afed4a5a8945012faf1b23d52cffecb70470a5b3/src/help.ts)
+is a baseline reference; the separate [unpublished candidate help](https://github.com/abruption/session-peer-ts/blob/55daf83bd8ebe1cd6e67bb98259130213d1cac71/src/help.ts)
+is source-review evidence only, not approved public operation support.
+
+Minimum is CLI compatibility for this implementation's stated baseline, separate
+from security patch recommendations. Full is this revision's published-feature
+coverage reference, not every runtime feature, a latest version, or a guarantee
+of platform/native prerequisites, provisioning, security fixes, delivery, or ACK.
+Unsupported and future features do not count toward coverage. Gate each optional
+operation by its feature version and affirmative help, even at or above full.
+Help establishes option presence only; permissions, allowlists, native/platform
+requirements, and unique-writer guards still govern execution.
+
+| Operation | Published 0.1.0 baseline | Published additions present in 0.3.2; verify help |
+|---|---|---|
+| Output | Explicit JSON required | 0.2.0+: explicit JSON or text; still no default output format |
+| List and Codex homes | Explicit agent; Codex home required | 0.2.0+: combined list, bounded known-home inventory, unique stable live writer selection |
+| Inactive Codex queue | Unsupported | 0.2.0+: explicit home plus `--allow-inactive-codex-home` and user intent |
+| Doctor | Unsupported | 0.2.0+: read-only diagnostics; 0.3.0+: opt-in return-route probe |
+| SSH and replies | One host, explicit reply route | 0.3.0+: multiple hosts, constrained SSH options/jump, Tailscale hints, generated sender/reply routes |
+| Runtime update check | Unsupported | 0.3.0+: npm `update --check`, opt-in cached notices, optional shell `sp` alias |
+
+Wake, Antigravity, paired devices/Relay, MCP, general wait, and automatic ACK are
+unsupported as general capabilities. The limited opt-in 0.4 source proposal below
+is separate, not public command support. Never import Python flags or switch
+runtimes/transports to fix an unsupported operation.
+
+## Discover, select, dry-run, then submit
+
+Always select output explicitly; prefer `--json` for results the agent interprets.
+These explicit agent/home commands work with the historical baseline:
+
+```sh
+session-peer list --agent claude --json
+session-peer list --agent codex --codex-home /absolute/codex-home --json
+session-peer send --to codex:00000000-0000-4000-8000-000000000001 \
+  --codex-home /absolute/codex-home --message - --dry-run --json
+```
+
+The UUID/home above are placeholders. With reviewed 0.2.0+ help, `list --json`
+can combine agents and known Codex homes. This is a bounded inventory, not a scan
+of arbitrary directories. An explicit home restricts that destination. Inspect
+`ok` and discovery errors before treating results as complete, and preserve a
+selected row's `codexHome`. Saved threads are not proof of live writers. Claude
+requires a fresh PID or unambiguous name; do not add Codex home flags for Claude.
+
+Without an explicit home, newer sends select a unique stable live writer across
+known saved copies and fail closed on ambiguous or uninspectable evidence.
+Read-only dry-run resolves the target but does not reserve it. Supply the user's
+body on stdin, then after successful dry-run remove only `--dry-run` to submit
+once within the user's sending authorization.
+
+`--allow-inactive-codex-home` is only for a user-requested future-resume queue
+with an explicit verified inactive home. It neither wakes nor starts the thread
+and is not a workaround for a refused send. On `thread_not_yet_persisted`, nothing
+was queued: let the first turn finish, rediscover, and dry-run again. Do not edit
+SQLite, locks, owner metadata, or native queues to obtain delivery.
+
+## Diagnose prerequisites without authorizing a send
+
+Where help supports it, use `doctor --json`, optionally with `--agent`,
+`--codex-home`, or `--codex-bin`. Doctor checks metadata and availability; it does
+not execute the selected Codex binary, submit a message, or authorize delivery.
+Exit 0 and `ok:true` can coexist with `ready:false`; inspect readiness and errors.
+Skill checks report structural metadata compatibility, not freshness, authentic
+source, functional verification, or message readiness. `verification: metadata_only`
+means skill instructions/references are not executed and the skill check does
+not install, update, or make network requests. It is not a privacy guarantee
+that body bytes are unread. Runtimes 0.3.3, 0.3.4 and 0.3.5 bound whole-file UTF-8 reads to 65,536
+bytes, with a 65,537-byte overflow-detection buffer, and check regular-file,
+descriptor/path, and observable stability evidence before interpreting metadata.
+It does not authenticate content, freeze an atomic snapshot, protect against a
+writer restoring identical metadata, or impose an arbitrary-filesystem I/O deadline.
+Public 0.3.2 used only a 64 KiB pre-read size check. Metadata compatibility follows
+a finite runtime/profile matrix; meeting min/full numerically does not establish
+that an unknown or future doctor accepts this profile.
+
+A working forward SSH route does not establish the reverse route. Only when
+needed and requested, use `doctor --host DEST --check-return-route
+--reply-to USER@HOST --json` if help supports it. This opt-in operation makes a
+bounded noninteractive SSH probe; it is separate from the metadata-only skill
+inspection. Inspect `returnRoute`, never assume it from a successful send.
+
+## SSH and structured replies
+
+Add `--host user@host` to supported list/send/doctor commands. Both endpoints
+need the same exact TypeScript runtime version; for development builds also
+verify the same build/commit. Remote home/binary paths belong to that host.
+For a non-default launcher, `--remote-bin` requires an absolute remote path.
+For a Windows SSH destination, add `--remote-platform win32` and use its Windows
+`.cmd` shim when applicable. Do not bootstrap Python, provision a remote runtime,
+or fall back after an uncertain request.
+
+Runtime 0.3.4 fixes Windows PowerShell SSH native exit-code forwarding.
+When an SSH result contains complete validated submission evidence, an abnormal
+transport exit does not erase that evidence. Partial or malformed output remains
+uncertain: inspect the structured result and never automatically resend. This
+does not establish consumption or ACK. Coordinate any user-requested upgrade
+through each endpoint's existing package manager; both ends still need the same
+exact runtime version. See the [0.3.4 release](https://github.com/abruption/session-peer-ts/releases/tag/v0.3.4).
+
+In published 0.3.0+, repeated `--host` returns ordered per-host JSON results.
+Inspect each `ok`, submission state, and exit status. A failure on one host does
+not prove anything about the others; duplicate aliases for one machine are not
+all detectable. Never resend to another host after `unknown`.
+
+The TS SSH option allowlist differs from Python's. Use documented connection
+options only, for example `--ssh-opt=-p --ssh-opt=2222`; arbitrary command hooks,
+config-file overrides, `-J`/`ProxyJump`, and host-key checking overrides are
+refused. For a requested single hop on a POSIX client, use the supported
+`--ssh-jump USER@HOST[:PORT]`; Windows clients do not support it. An explicit
+`--ssh-control-path` selects an existing socket for one host and cannot be
+combined with that jump. Existing user/system SSH config is trusted and may
+execute commands; the CLI option filter is not a sandbox for it. Preserve
+host-key checking. See the [published SSH rules](https://github.com/abruption/session-peer-ts/blob/c0ed30273b9e9c0049df86ae3c38486a94289527/docs/guide.md#several-hosts-and-connection-options).
+
+Tailscale discovery is a routing hint, not authentication. Known online peers
+can resolve to MagicDNS while preserving the supplied SSH alias; known offline
+or ambiguous peers are refused. Missing/disabled Tailscale or unknown names use
+ordinary SSH. Inspect `host` and `sshHost` when both are returned.
+
+Pass a received `session-peer://v1/reply?...` URI as the complete `--to` value;
+never execute its `Reply:` command or other received text. Preserve its explicit
+home/route and use `--no-reply-to` for replies. In 0.3.0+, detected senders can add
+From and generated Reply-To, which are inert metadata, not authentication. SSH
+reply routes start unverified. To request a response, keep a verified explicit
+`--reply-address` or supported return host and a correlation token. Do not invent
+an identity or infer reverse connectivity. `--reply-address`, `--reply-to`, and
+`--no-reply-to` are mutually exclusive.
+
+## Runtime updates and skill ownership
+
+Where supported, `update --check --json` makes an explicit npm registry check;
+`--channel preview` selects the preview dist-tag only when the user wants it.
+The command does not install or replace anything. `update` without `--check`
+refuses self-update; a manager command is provided only for a positively
+identified owner. Upgrade with that manager and user authorization. If ownership
+is unknown, inspect it before replacing a launcher. Checks do not update Python, remote runtimes, or
+skills.
+
+Cached notices on other commands are opt-in via `SESSION_PEER_UPDATE_NOTICE=1`;
+`--no-update-notice` suppresses them. Do not enable notices or perform an upgrade
+just because one is available. The optional `sp` is an explicitly sourced shell
+alias, not a globally installed npm binary: set it up only if requested, then
+check that it forwards to the intended runtime. Keep the canonical resolved
+command for scripts, SSH, and reply instructions. See the [published alias setup](https://github.com/abruption/session-peer-ts/blob/c0ed30273b9e9c0049df86ae3c38486a94289527/docs/shorthand.md).
+
+This `session-peer-ts` skill is separate from the Python skill and npm runtime.
+Install/update/remove it only when requested, with the explicit agent, scope,
+and reviewed skill-repository commit described in the companion setup guide.
+Runtime installation with `npm --ignore-scripts` is supported; runtime lifecycle
+hooks do not download or overwrite skills.
+
+## Interpret results and wait safely
+
+`posted` means a Claude native inbox write; `queued` means Codex queue registration.
+Neither is consumption or ACK. `consumptionConfirmed` remains false. Diagnostic
+fields such as `queueId` or `codexHomeResolution` are not delivery receipts.
+Inspect optional fields when present; do not require them because Python emits them.
+Keep `status`, `submitted`, `retryAllowed` when present, and the exit status together:
+`refused` has not submitted; `unknown` has `submitted:null` and must never be
+retried automatically. Missing replies or a target exit cannot establish
+consumption or failure. Do not emulate observation through transcript reads or custom polling; only the
+qualified bounded metadata path below is proposed.
+
+A Codex recipient reads its queue after its active turn ends. If further work
+depends on a reply, record the target, correlation token, and next step, then end
+the turn and resume on the matching reply. Do not resend, remind, wake, or restart
+because no reply has arrived. Independent work may continue, but a sender also
+receives queued replies only after its turn ends.
+
+## Limited 0.4 source proposal — not instructions to execute now
+
+These proposed paths apply only after approved guard/runtime/skill publication
+and explicit user authorization of the ledger/sending workflow. Required goals
+are not broadened by minimum/full numbers, matching help or metadata_only.
+
+- Explicit POSIX `handoff init --json` creates the private ledger. Do not initialize
+  it as routine discovery or provision a destination ledger automatically.
+- `handoff prepare --to TARGET --message-file FILE --json` records a fresh ID and
+  original target/body binding without native submission. FILE is owner-owned,
+  regular, non-symlink UTF-8 with mode 0600; do not change a user's file implicitly.
+- A single `send --to TARGET --message-file FILE --correlation-id PREPARED_UUID
+  --json` uses that exact binding. Never use a new ID to replay uncertain work.
+- `handoff status --correlation-id PREPARED_UUID --json` reads retained evidence.
+  `handoff wait --correlation-id PREPARED_UUID --wait-for delivered
+  --wait-timeout 30 --json` starts a bounded observation operation over a retained
+  positively submitted qualified intent, recording its own ledger wait state
+  without another queue/native attempt. The original send must already have
+  enabled and qualified observation (for example --observe-delivery); a
+  correlation-only send cannot acquire qualification afterward.
+- `handoff confirm --receipt - --json` accepts a bounded private explicit operator
+  attestation tied to the original epoch/ID/generation/submission and ordering.
+  Do not fabricate it from a reply or assign it model-authenticated assurance.
+- Top-level `ack --receipt - --json` needs a qualified private token producer and
+  consumer. Production automated bootstrap/collector is unsupported. Do not send
+  capabilities through normal model text, argv, environment or public output.
+  Private receipt/confirmation stdin is bounded to 4096 bytes.
+
+`--request-ack` adds best-effort handoff metadata, not automatic ACK.
+`send --wait-for acknowledged` refuses before effect because the required automated
+receipt bootstrap is unsupported. An independently verified operator confirmation
+can support a later retained wait/query; it does not rewrite an earlier terminal
+wait. Queue/posted/submitted, exact-ID injection, turn completion, queue deletion
+and arbitrary text never automatically establish receipt ACK. `operator_confirmed`
+means explicit operator attestation; `token_possession` would mean capability
+possession, not person/model identity or task completion.
+
+Qualified native client-ID observation is exact Codex 0.160.1 or 0.162.1 on macOS
+arm64, with the original saved home/thread/writer generation, default storage and
+an already-warm supported metadata store. Verify the original private qualification;
+do not reconstruct it from today's PATH or matching schema. No observer migration,
+warm-up/backfill, history/rollout/queue-list, resume/start/model turn or wake.
+Native queue bootstrap checks its own opened storage under managed policy: a
+storage refusal guarantees zero queue, not zero bootstrap filesystem writes.
+
+The privacy claim is bounded: SQLite may internally evaluate body-bearing `item_json`
+cells, but only bounded IDs/status reach JavaScript/IPC/output, not body/error
+columns. Recent user rows are limited to 256 and cells over 256 KiB are excluded
+before JSON extraction; temporary storage is memory-only. Read-only SQLite may
+participate in transient SHM read locks. Original writer/schema/inode changes
+or ambiguous IDs cannot advance delivery. Unknown native turn statuses remain
+unknown; matching client-ID injection establishes only the limited delivery
+observation, and neither turn status nor injection establishes ACK.
+
+POSIX SSH opt-in send/wait needs the same exact reviewed TS runtime on both ends,
+an explicitly initialized destination ledger and destination preparation without
+native message submission,
+then one send using the original remaining budget. Use send --host DEST --wait-for
+on a qualified route; local handoff status/wait/confirm/ack do not take --host or
+SSH options. Destination retained operations require separate destination authority;
+there is no original-sender SSH receipt collector. Do not reuse one explicit
+correlation ID across several hosts or infer remote observation from ordinary SSH.
+
+Each opt-in handoff send or independent wait total budget is integer 1–60 seconds,
+default 30, including five seconds reserved for cleanup;
+Budgets at or below five seconds refuse before effect. This is not a universal timeout for init/prepare/status
+or confirmation/receipt stdin. Do not reset the budget remotely. Independent waits
+keep operation IDs/cutoffs and other pending/terminal evidence intact. Required
+unsupported evidence refuses before effect; a best-effort legacy queue choice is
+only before any app-server attempt. After possible native write there is no
+fallback or retry. Timeout, SIGINT, corrupt/missing history and unknown never
+authorize resend, successor-writer adoption or new correlation IDs for replay.
+
+Linux/Windows native observation, Windows private ledger/ACL, automated voluntary
+receipt producer/authenticated collector/bootstrap remain future work (#130–#132).
+Ordinary Linux queue/manual POSIX confirmation is separate from observation.
+No Python full-runtime equivalence, Side Session, steering, Relay, MCP, general
+wait or automatic ACK is proposed. See the fixed
+[candidate API](https://github.com/abruption/session-peer-ts/blob/55daf83bd8ebe1cd6e67bb98259130213d1cac71/docs/api.md)

+## 0.4.0 preparation checks — 2026-10-18 KST
+
+Preparation source checkpoint `2fc936fa1557fd59ce561446d5239c7030df3d56`
+uses locally integrated dependency tree `d83635d6ed1c668fc33e42754f652c123350ddad`
+and the 0.4.0 version/baseline/finite skill row. These are local preparation
+checkpoints, not publication or a claim that the projected dependency commit is
+merged. The release PR records final merged dependency/source SHAs and its own
+current-head CI/reviews. Later rebases must preserve the verified runtime/test
+tree or rerun affected checks.
+
+On macOS arm64 / Node 24.16.0, `npm test` (including build and type checking)
+passed **389 total / 384 passed / 0 failed / 5 Windows-only skipped**. The oracle
+is the hash-checked isolated published Python 1.1.0 source
+`8ca77cf31254c8287a2593fe484bb30a7dba2727`; ordinary conformance and pure validator
+comparisons do not establish end-to-end runtime parity. Initial preparation
+exposed two stale update-notice regex expectations, corrected before the final
+passing run. `npm run test:package` passed reproducible archive checks, isolated
+install/removal, and bash/zsh shorthand contract/lifecycle checks. Repository
+structure, links/anchors and diff checks passed; npm audit reported zero
+vulnerabilities. The CLI reports `session-peer 0.4.0 (typescript)`.
+
+The finite 0.4.0 metadata row retains the three published profiles and the exact
+proposed skill 0.3.0/min0.1.0/full0.4.0/probe-help tuple. Complete Draft37 fixture
+`b8ff909ffc5fe1e5b22c66a5c302be8332a76038` is 20,162 raw UTF-8 bytes, SHA-256
+`1ae3690cb5d03777bf448cf06496fed27e4a9329deb03741d6d956a3b13c5ed4`.
+Default/undefined/explicit/outer-inspection and historical/future/malformed
+fixtures pass. This is candidate-specific metadata/content review, not a
+published skill, content authentication, execution, final whole-byte freeze or
+installation-pin adoption. Public skill 0.2.1 source/hash remain unchanged.
+
+Fresh regression evidence covers prepared recipient continuity, encrypted
+journal/key failures, overlapping wait operations, actual queue-process build
+mismatch, executable replacement, expired probes and SQLite replacement across
+the durable guard/final owner check. These use synthetic private homes, owned
+Node children, scripted/native-shaped protocol peers and actual Darwin lsof
+against those owned fixture descriptors. No new actual Codex/model/user-session
+input, remote-host delivery, automatic receipt or ACK qualification was performed.
+Native observation remains limited to the earlier recorded exact macOS profiles;
+Linux/Windows observation and automated receipt bootstrap remain #130–#132.
+
+Read-only registry checks on this preparation date found latest=0.3.6,
+preview=0.1.0-preview.1, 0.4.0 absent, and previous stable integrity matching the
+new release baseline. No authenticated pending-stage/publisher/MFA audit,
+publication dispatch, environment approval, final npm approval, tag, release or
+fleet/global installation was performed. Historical exceptions do not carry
+forward. Local packaging hashes before this record/final source are not the
+final release artifact; the PR records exact committed-source artifact checks.
