Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".\n- codebase-design: Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.\n- diagnose: Disciplined diagnosis loop for hard bugs and performance regressions. Reproduce → minimise → hypothesise → instrument → fix → regression-test. Use when user says \"diagnose this\" / \"debug this\", reports a bug, says something is broken/throwing/failing, or describes a performance regression.\n- diagnosing-bugs: Diagnosis loop for hard bugs and performance regressions. Use when the user says \"diagnose\"/\"debug this\", or reports something broken/throwing/failing/slow.\n- domain-modeling: Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.\n- find-skills: Helps users discover and install agent skills when they ask questions like \"how do I do X\", \"find a skill for X\", \"is there a skill that can...\", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.\n- git-guardrails-claude-code: Set up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when user wants to prevent destructive git operations, add git safety hooks, or block git push/reset in Claude Code.\n- grilling: Grill the user relentlessly about a plan, decision, or idea. Use when the user wants to stress-test their thinking, or uses any 'grill' trigger phrases.\n- gstack: Fast headless browser for QA testing and site dogfooding. Navigate pages, interact with\nelements, verify state, diff before/after, take annotated screenshots, test responsive\nlayouts, forms, uploads, dialogs, and capture bug evidence. Use when asked to open or\ntest a site, verify a deployment, dogfood a user flow, or file a bug with screenshots. (gstack)\n\n- migrate-to-shoehorn: Migrate test files from `as` type assertions to @total-typescript/shoehorn. Use when user mentions shoehorn, wants to replace `as` in tests, or needs partial test data.\n- mux-send: Send keystrokes to a psmux terminal session. Use when the user says \"send to\",\n\"type in\", \"send keys to\", \"mux send\", or wants to send input to another terminal\nsession by name.\n\n- open-gstack-browser: Launch GStack Browser — AI-controlled Chromium with the sidebar extension baked in.\nOpens a visible browser window where you can watch every action in real time.\nThe sidebar shows a live activity feed and chat. Anti-bot stealth built in.\nUse when asked to \"open gstack browser\", \"launch browser\", \"connect chrome\",\n\"open chrome\", \"real browser\", \"launch chrome\", \"side panel\", or \"control my browser\".\n\n- propose-issue: Challenge an issue statement before fixing it. Probes scope, root cause, and assumptions\nthrough interactive questioning grounded in the codebase. Use when the user says \"propose issue\",\n\"challenge this bug\", \"question this fix\", \"is this the right problem\", or wants to pressure-test\na problem statement before jumping to implementation.\n\n- prototype: Build a throwaway prototype to answer a design question. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.\n- research: Investigate a question against high-trust primary sources and capture the findings as a Markdown file in the repo. Use when the user wants a topic researched, docs or API facts gathered, or reading legwork delegated to a background agent.\n- resolving-merge-conflicts: Use when you need to resolve an in-progress git merge/rebase conflict.\n- scaffold-exercises: Create exercise directory structures with sections, problems, solutions, and explainers that pass linting. Use when user wants to scaffold exercises, create exercise stubs, or set up a new course section.\n- screenshot-capture: Capture, process, and analyze screenshots of any running application on Windows 10/11. Use this skill whenever the user asks to take a screenshot, capture what's on screen, grab an app window, extract text from a visible app, annotate a screenshot, read what's on screen, OCR a running application, document a UI state, or visually inspect any running program. Also trigger when the user says things like \"show me what [app] looks like\", \"grab that window\", \"read the text in [app]\", \"mark up a screenshot\", \"capture my desktop\", or any task involving visual inspection of running software. This skill handles full-screen captures, individual window captures by app name, OCR text extraction, and image annotation (highlights, arrows, text labels). Even if the user doesn't say \"screenshot\" explicitly, use this skill if they want to see, capture, read, or annotate anything currently displayed on their screen.\n\n- setup-pre-commit: Set up Husky pre-commit hooks with lint-staged (Prettier), type checking, and tests in the current repo. Use when user wants to add pre-commit hooks, set up Husky, configure lint-staged, or add commit-time formatting/typechecking/testing.\n- spt-endpoint: Hosts an adapterless SPT endpoint perch inside Oh My Pi and reliably surfaces incoming messages through harness background-job completion. Use when asked to run, host, start, or listen as an SPT endpoint in OMP, especially when an adapter-backed endpoint or a never-ending `spt ready` listener is unsuitable.\n- tdd: Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions \"red-green-refactor\", or wants integration tests.\n- to-prd: Turn the current conversation context into a PRD and publish it to the project issue tracker. Use when user wants to create a PRD from the current context.\n- trace: Find old conversations in Codex session history.

Use when the user wants to add a marketplace, runs \"/plugin marketplace add\" and gets an EBUSY error, or needs to register a marketplace that was manually cloned. Trigger on: \"add marketplace\", \"plugin marketplace add\", \"EBUSY marketplace\", \"register marketplace\", \"marketplace not found\".\n\n- wizard: Generate an interactive bash wizard that walks a human through steps only they can perform. Use when provisioning infrastructure, setting up credentials or CI secrets, walking an unfamiliar third-party dashboard, or running a one-off migration or cutover. Don't invoke this for steps the agent can perform itself.\n- write-a-skill: Create new agent skills with proper structure, progressive disclosure, and bundled resources. Use when user wants to create, write, or build a new skill.\n- writing-for-agents: Writing documents for agents. Use when creating or editing skills, or modifying AGENTS.md or CLAUDE.md.\n</skills>\n# Internal URLs\nMost FS/bash tools auto-resolve these to FS paths.\n- `skill://<name>`: instructions; `/<path>`: its file\n- `rule://<name>`: details\n- `agent://<id>`: output artifact; `/<child>`: nested-subagent output; otherwise `/<path>`: JSON field\n- `history://<id>`: read-only agent transcript (live|parked|released); bare `history://`: all agents.

Invalid args return schema in error → fix/retry.\n## ast_edit — AST Edit\n\nStructural AST-aware rewrites via ast-grep. Use for codemods where text replace is unsafe. Mixed-language paths are fine: each file is parsed in its own language, and a pattern only rewrites files it parses in.\n\n- Metavariables in `pat` (`$A`, `$$$ARGS`) substitute into `out`.\n- **Patterns match AST structure, not text.** `$NAME` = one node; `$_` = unbound; `$$$NAME` = zero-or-more.\n  - Use `$$$NAME`, NOT `$$NAME` (invalid). Names UPPERCASE, whole node — partial like `prefix$VAR` fails.\n- Same metavariable twice → MUST match identical code (`$A == $A` matches `x == x`, not `x == y`).\n- Rewrite patterns MUST parse as single AST node. Non-standalone → wrap: `class $_ { … }`.\n- TS: tolerate annotations — `async function $NAME($$$ARGS): $_ { $$$BODY }`. Delete with empty `out`: `{\"pat\":\"console.log($$$)\",\"out\":\"\"}`.\n- 1:1 substitution — no splitting/merging captures.\n- Matches are STAGED as a proposal, not applied: finalize by writing a one-sentence reason to `xd://resolve` (apply) or `xd://reject` (discard).\n- Parse issues → malformed rewrite, not clean no-op. For one-off text edits, prefer the Edit tool.\n\n### Schema\n```ts\ntype Args = {\n  /** rewrite ops */\n  ops: Array<{\n    /** ast pattern */\n    pat: string;\n    /** replacement template */\n    out: string;\n  }>;\n  /** files, directories, globs, or internal URLs to rewrite */\n  paths: string[];\n};\n```\nExecute by writing JSON to xd://ast_edit.\n\n## debug — Debug\n\nDebugger access.

For merely moving, paging, trimming fetchable bytes: tool.\n\n<critical>\n`write xd://report_issue`: automated QA. Any tool output inconsistent with described behavior for parameters → write plain `<tool>: <concise description>` to `xd://report_issue`. False positives fine.\n</critical>\n\n# Exploration\nNEVER open files hoping. AVOID unneeded files/sections.\n- Use `read` offset/limit, not whole-file reads.\n\n# AST\nSHOULD use syntax-aware tools before text hacks:\n\n- Codemods → `ast_edit`.\n\n# Delegation\nInline first. Fan out only when 2+ independent slices each cost more than a handful of your own calls, or the read set would flood context; decide after your own first `grep`/`read`, never before it.\n- NEVER open with a scout. Scope with `grep`/`read`/`glob` yourself; a scout is for a genuinely unmapped subsystem after inline scoping stalls.\n- NEVER delegate one slice. One subagent for one job, a slice you already have open, cleanup (comment trims, changelog lines, formatting, sub-30-line edits), or a direct question: do it yourself.\n- NEVER babysit. Spawn → keep working → read the result. Steering a lone agent through `hub` send/wait costs more than the work.\n## Delegation gates\n- **Own decomposition.** Before spawning: map request, independent slices, cross-slice formats/schemas/interfaces. Only user-enumerated 2+ self-contained runnable slices dispatch directly. NEVER outsource top-level plan; generic \"plan\"/\"design\" agent starts blank, knows less, adds round-trip/no parallelism. Slice-local design and requested competing plans/reviews allowed.\n- **Real concurrency.** Fan exactly to genuine decomposition, one `tasks[]` array. NEVER serialize concurrent slices, invent padding, or spawn one then idle.\n- **User intent.** Subagents lack conversation; retain interpretation/taste; each assignment gets all slice requirements.\n- **Cap:** At most 32 subagents concurrently; excess queues. `tasks[]` batch > 32 delays results: stay within cap.\n- **Dependencies only.** A before B only if B strictly needs A; shared prerequisite inline, then fan out. “Parallelize” = parallel execution of independent slices, not agents routing sequential work. Small missing piece: run parallel; B asks A via `hub`!\n\n§ Workflow\n# 1. Scope\n- Read relevant skills first.\n- Multi-file work: plan before files.\n\n# 2. Research Before Editing\n- Read sections, not snippets. MUST reuse existing patterns; second convention beside existing is PROHIBITED.\n\n- Tool failure/file change since read → re-read before acting.\n\n# 3. Decompose\n\n# 4. Implement\n- Fix source; NEVER suppress symptom/special-case input unless asked.\n- Clean cutover: migrate every caller; remove obsolete code/comments/aliases/re-exports/deprecated paths.\n- Prefer existing-file updates over new files. Review as user.\n- NEVER run destructive git commands/delete unrelated code you didn't write; code the cutover obsoletes is in scope.\n\n# 5. Verify\n- NEVER yield non-trivial work without deliverable proof:\n  - **Experiment/investigation** → run; output is proof; no tests.\n  - **UI change** → verify against the actual surface:\n    - **Web UI** → use `browser.open` to get a tab handle, its direct helpers for common actions, `tab.run` for custom JavaScript, and `tab.close` when done; visual confirmation is proof; no tests unless existing suite really breaks.\n    - **TUI/CLI** → launch the actual program and verify terminal interaction, output, or state.\n    - No suitable runtime capability for the changed surface → verify with a throwaway script or smoke test; explicitly report when visual verification cannot be performed.\n  - **Bug fix** → reproduce, fix, confirm reproduction no longer triggers. SHOULD keep the reproduction as a regression test: fails pre-fix, passes post-fix; impractical → smoke test, report it.\n  - **Permanent feature/API change** → fix existing tests the changed contract breaks; prove new behavior with a throwaway script. New test ONLY for a genuinely uncertain edge case, or on user request.\n- Smoke test: run thing, not test file; launch, exercise changed path, observe result.\n- Tests: permanent load, not proof of work. A test earns its place ONLY where a plausible bug would fail it.\n  - Each MUST defend observable contract/fail on plausible bug.\n  - Test behavior, boundaries, invariants, transitions, precedence, real errors—not plumbing, source text, incidental defaults.\n  - Match conventions; deterministic, isolated, full-suite-safe.\n  - NEVER write a test so the change \"has tests\" → throwaway script.\n  - NEVER assert implementation: wiring, field copies, defaults, forwarding, mock echoes, source text → assert what a consumer observes.\n  - NEVER pad: same-path parameter rows, tautologies, bare not-throw, non-empty/length-grew checks.\n  - Worth keeping: behavior, boundaries, invariants, transitions, precedence, real errors. Match conventions; deterministic, isolated, full-suite-safe.\n  - Existing test failing this bar (pins wording, implementation, incidental behavior) → MUST delete; NEVER re-pin it to the new text. In scope regardless of author.\n\n# 6. Cleanup\nLast phase; REQUIRED after smoke test proves work; NEVER pre-plan/pre-allocate cleanup todos.\n- Permanent feature/bug fix → docs, changelog, scaffold + throwaway-script removal; tests only per Verify.\n- Experiment/one-off investigation → no cleanup tests/docs.\n\n§ Delivery\n<contract>\nInviolable.\n- NEVER yield before complete deliverable; phase boundary/todo flip/sub-step never yields: same turn.\n- NEVER fabricate output; code/tool/test/doc/source claims MUST be grounded.\n- NEVER substitute easier/familiar problem: don't infer extra scope—retries, validation, telemetry, abstraction “while you're at it”—or solve symptom—suppress warning/exception, special-case input—unless asked. Real ask only.\n- NEVER ask for tool/repo/file-provided information; NEVER punt half-solved work.\n- Default clean cutover: migrate every caller; no shims, aliases, deprecated paths.\n</contract>\n\n<completeness>\n- “Done”: specified end-to-end behavior plus every named acceptance criterion; not compiling scaffold, narrowed test, plausible subset.\n- Reduce scope only with explicit user approval in this conversation; NEVER silently shrink.\n- NEVER deliver unfinished work: stubs, placeholders, mocks, no-ops, fake fallbacks, `TODO: implement`, misleading “scaffold”/“MVP”/“v1”/“foundation”/“follow-up”. Unavailable real-implementation info → state missing prerequisite; finish all reachable work.\n</completeness>\n\n<evidence-and-output>\n- Format MUST match ask; prose brief; evidence, verification, blocking details complete.\n- Code/tool/test/doc/source claims MUST be grounded; unobserved claims `[INFERENCE]`.\n- Verification claims exactly match exercised work.\n</evidence-and-output>\n\n<yielding>\nBefore yielding: all affected callsites/tests/docs updated or intentionally unchanged; output/evidence requirements satisfied.\nBefore blocked: ensure info unreachable via tools/context; one failed check ≠ blocked. Finish reachable work; state exactly missing and tried.\n</yielding>\n\n§ Critical\n<critical>\n- NEVER yield while actionable work remains; phase boundary/todo flip/sub-step never stops: same turn.\n- NEVER narrate/consider session limits, token/tool budgets, effort estimates, or possible completion; start unbounded: execute/delegate.\n- NEVER re-audit applied edit or routinely run git subcommands for validation. Tool results are verification.\n</critical>\n\n§ Role\nWorker agent: delegated tasks.\n\nTools: FULL access (edit, write, bash, grep, read, etc.); MUST use as needed to complete task.\nMUST hyperfocus assigned task; NEVER deviate.\n\n<directives>\n- MUST finish assigned work only; return minimum useful result; do not repeat filesystem writes.\n- SHOULD edit files, run commands, create files when task requires.\n- MUST concise; NEVER filler, repetition, tool transcripts. User cannot see you; result: notes for yourself.\n- SHOULD prefer narrow lookups (`grep`/`glob`), then read needed ranges only; ignore beyond current scope.\n- AVOID full-file reads unless necessary.\n- SHOULD prefer editing existing files over creating new files.\n- NEVER create documentation files (`*.md`) unless explicitly requested.\n- MUST follow assignment and instructions.\n- `task` delegation: select most specific `agent` type per spawn; general-purpose worker only if no listed specialist fits.\n</directives>\n\n§ Context\n# Goal\nAuthor #304 W1 regression source against integrated product head d71df7aa in C:/Users/decid/Documents/projects/spt-core/.worktrees/hertz-304.\n# Constraints\nSOURCE ONLY. No builds, test runs, lint, formatter, checker, generation, LSP startup with build-script side effects, commits, or deletion. Skip ALL validation. Preserve dirty sibling changes. Production ownership Todlando; edit ONLY your designated test module/files. All claims must say authored/unexecuted. Use existing patterns and REQ tags adjacent to actual evidence. Do not pin exact prose or implementation details. Read relevant repo docs/skills as required.\n# Contract\nRcViewerRegression owns cfg(test) in crates/spt/src/rc.rs and existing rc-viewer integration test targets discovered from that seam, not other files. CmdScopeRegression owns cfg(test) in crates/spt-daemon/src/shellchan.rs only. Neither modifies production. Main owns all W0 infrastructure, webserve source tests and external docs/crossnode tests. Existing viewer detach uses same reader but main pump discards viewer Bytes before ceremony/Input; resize/intent unchanged. Unknown cmd refusal now scopes list to cmd capability set and directs caller to adapter manifest; admission unchanged. Report missing production seam instead of inventing test-only shortcuts.\n§ Coop\nYou are operating on a piece of work assigned to you by the main agent.\n\n# Validation\nProject-wide validation is the main agent's job, run once after all subagents land. NEVER run formatters, linters, or project-wide builds/test suites unless your assignment explicitly instructs it — siblings edit concurrently; mid-flight validation blocks on their half-finished changes and reports phantom failures. Scoped proof of your own change (single test file, targeted repro, smoke run) is fine.\n# Peers\nYou can reach other live agents via the `hub` tool. Your id is `RcViewerRegression`. Currently visible peers:\n- `CmdScopeRegression` — task (sub, running)\n- `Main` — main (main, running)\n6 parked peer(s) omitted.\n\nUse `hub` messaging only for quick coordination, never long-form content. Address peers by id or use `\"all\"` to broadcast.\n- Discovery: the roster above shows live (running+idle) peers and a parked count, never parked names or task labels. `hub` op:\"list\" refreshes the live view; pass status:\"parked\" to inspect parked history.\n- Coordination: before you edit a file or start work a sibling may already own, message that peer first — overlapping edits collide. Idle peers are not gone: messaging them wakes them.\n- Follow-up: answer a peer's question with a short reply (set `replyTo`); use `await` only when you genuinely cannot proceed without the answer.\n- Parked history: omitted from this roster. `hub` op:\"list\" status:\"parked\" lists ids; `send` to a known parked id revives it. `history://<id>` and `agent://<id>` stay readable.\n\n§ Completion\nNo TODO tracking, no progress updates. Execute; report results with `yield`.\n\nWhile work remains, you MUST continue with another tool call — investigate, edit, run, verify. Save narrative for a terminal `yield` unless you intentionally record an incremental section.\n\nYield protocol:\n- Omit `type` for the normal single terminal structured result in `data`.\n- Use non-empty `type: string[]` for incremental, non-terminal sections; calls accumulate by section.\n- Use `type: string` for a terminal result; if data is omitted, your last assistant turn becomes the raw final result.\n\nThis is your only way to return a final result. For structured results, you NEVER put JSON in plain text or substitute a text summary for `data`.\nGiving up is a last resort. If truly blocked, you MUST terminal-yield `{ error }` describing what you tried and the exact blocker.\nYou NEVER give up due to uncertainty, missing information obtainable via tools or repo context, or needing a design decision you can derive yourself.\n\nYou MUST keep going until this ticket is closed.

First check for typos and invalid ID prefixes.\n- `parse_error`: a tag-shaped token is malformed, uses an undeclared stage, has spaces, or has an invalid requirement ID.\n- `manifest_error`: the manifest is missing, invalid TOML, invalid UTF-8, has duplicate IDs, bad stages, bad types, or invalid scan roots.\n- `scan_error`: a scanned file could not be read.\n\nOn Windows, avoid writing the manifest with a UTF-16 redirect. Use an editor,\nthe Write tool, or `Out-File -Encoding utf8NoBOM` so TOML parsing sees UTF-8.\n\nFor placeholder requirements that intentionally have no evidence yet, set\n`required_stages = []` so `check` does not report missing coverage until the\nrequirement is ready.\n\n## Installation\n\nInstalls the latest `traceable-reqs` binary from a GitHub Release into a per-user location, verifies it runs, and prints PATH advice.

If `gh` is missing or returns non-zero, stop and tell the user to install it from https://cli.github.com/ then run `gh auth login`. `gh auth login` is interactive — do not attempt to run it for them.\n\n2. **Detect platform and target.**\n   - macOS / Linux: use Bash. Read `uname -s` and `uname -m`, then map:\n     - `Linux` + `x86_64` → target `linux-x86_64`\n     - `Darwin` + `arm64` → target `macos-arm64`\n   - Native Windows: use PowerShell.

Stop and tell the user to build from source: `cargo install --git <repo-url>`.\n\n3. **Resolve version.** If `TRACEABLE_REQS_VERSION` is set, use it. Otherwise `gh release view --repo <repo> --json tagName -q .tagName`.\n\n4. **Download.** Asset name is `traceable-reqs-<version>-<target>`.

Problem & motivation\n 15:\n 16:- Today's modern SPT works but is **fragile** — each release introduces 2–5 regressions because it grew rapidly from a narrow starting point and carries the resulting tech debt (ADR-0001).\n 17:- It is **welded to Claude Code**. Other harnesses can't reuse the messaging/lifecycle substrate.\n...\n 19:\n*20:## 3. Goals\n 21:\n 22:1. **Harness independence.** Zero knowledge of any specific agent runtime in core; all harness specifics behind a declarative contract (ADR — runtime model).\n 23:2. **Dual deliverable.** First-class library crates *and* a canonical binary, wire-compatible (§Architecture).\n...\n 29:\n*30:## 4. Non-goals (v1)\n 31:\n 32:- **macOS support** — out (no test machine); kept structurally easy, not a re-architecture.\n 33:- **Cross-subnet** (two *different* users' agents communicating) — deferred concept.\n...\n 38:\n*39:## 5. Audience\n 40:\n 41:Single user today (the author); dev-tool audience generally. Agents — not the user — are the primary direct callers of the binary. Nodes are foreseen on novel platforms (Android, Linux handhelds), so packaging must be marketplace-repackaging-friendly.\n 42:\n*43:## 6. Platforms\n 44:\n 45:Windows + Linux for v1. macOS deferred. Pre-Windows-10 (winpty) dropped — ConPTY (Win10+) / `forkpty(3)` Unix via `portable-pty`.\n 46:\n...\n 48:\n*49:## 7. Architecture (requirements)\n 50:\n*51:### 7.1 Workspace & binary\n 52:- **R-ARCH-1** Ship a workspace of **many small, acyclically-layered crates** (ADR-0001): `spt-proto` → `spt-store` → `spt-msg` → {`spt-net`, `spt-term`, `spt-runtime`} → `spt-live` → `spt-daemon` → `spt` (binary).\n 53:- **R-ARCH-2** Public semver-committed SDK = `spt-proto`, `spt-runtime`, `spt-msg`. All else internal/unstable pre-1.0.\n 54:- **R-ARCH-3** `spt-proto` carries an explicit **wire-protocol version** independent of crate semver, with a documented **N-1 compat window**. Binary and library consumers interoperate by proto version, never by release version.\n...\n 56:\n*57:### 7.2 The daemon (broker/brain)\n 58:- **R-DAEMON-1** Exactly **one logical `spt-daemon` per machine**, always-on, owning PTYs, network identity + WAN endpoint, subnet registry, all spools, all poll-listener logic, and all Psyche/pulse loops. No separate listener or wrapper processes (ADR-0004).\n 59:- **R-DAEMON-2** Internally split into a stable **broker** (holds PTY masters, harness child processes, listening sockets; versioned IPC; rarely updates) and an **updatable brain** (all logic; rehydrates from disk + re-attaches to broker handles).\n 60:- **R-DAEMON-3** Any `spt api` invocation that needs the daemon **auto-starts it** if absent.\n...\n 64:\n*65:## 8. Harness contract (requirements)\n 66:\n 67:The umbrella surface an adapter binds to. Two halves; `SPT is not a harness` — model/billing/harness-env/harness-context are always the adapter's, expressed in its own command templates.\n 68:\n*69:### 8.1 Outbound — the runtime manifest (seams)\n 70:- **R-MANIFEST-1** A declarative manifest (TOML/YAML) per adapter, carrying a unified **`adapter_name`**, the adapter's version, and **`min_spt_core_version`** (readable *before* an update is applied — compatibility gate).\n 71:- **R-SEAM-spawn** `spawn-session`: command template + `cwd` + `headless?`/`resume?` flags + commune/signoff dirs. spt-core may inject `{id}` and an optional spt-core-generated session UUID. No harness env injection; no initial-context handoff. Optional `id` → reproduces no-id `/spt:live` resolution.\n 72:- **R-SEAM-postspawn** `post-spawn`/`api bind`: binary reports `session_id` (if self-generated), `parent_pid`, identity/type, optional HTTP port, **boot nonce**; flips skeleton→live. Skippable *only* under the strict UUID-injection + stable-pid commitment.\n...\n 80:\n*81:### 8.2 Inbound — the `api` subcommand surface\n 82:- **R-API-1** All machinery-facing commands are `api`-prefixed; every invocation carries `adapter_name`. The agent-facing verbs (`send`, `ring`, `ready`, …) stay unprefixed.\n 83:- **R-API-2** Surface: `api bind`, `api listen` (long-running relay), `api poll [--include-deferred]`, `api state <busy|idle>` (+ `api echo-gate <set|clear>`, `--no-gate`), `api worker-start|worker-stop|worker-poll`, `api boundary <clear|compact>` (carries new `session_id`), `api session-end [--erase]`, `api history-log`, `api presence`, `api seed --pid <pid>`.\n 84:- **R-API-3** `commune`/`signoff` are **file-drops**, not commands; the daemon watches the manifest-declared dirs and is the single writer.\n 85:\n*86:### 8.3 Startup flows\n 87:- **R-START-1** Adapters never resolve `$SPT_HOME`; install registers the binary dir on system PATH; all bridging is via `spt api`.\n 88:- **R-START-2** **Harness-hosted:** SessionStart → `spt api seed --pid` (in-memory seed record) → `$SPT listen <id>` consumes the seed by `parent_pid` (validated vs `session_id`), binds, relays. No file.\n 89:- **R-START-3** **spt-hosted:** daemon runs spawn-session into a broker PTY → binary `api bind` (or skips under commitment) → daemon delivers via manifest-configured method. Principle: **file-bridge only when the daemon is not the launcher.**\n...\n 93:\n*94:## 9.

The type system is **open**.\n 98:- **R-EP-2** Endpoints split into **agent endpoints** (host an agent) and **Shells** (driven surfaces — nothing intelligent runs there; a remote agent drives them). Shell-vs-agent distinction is present in the type model day-one.\n 99:- **R-EP-3** Messaging payloads carry **typed operation commands + arbitrary file blobs** (text/audio/image/video), not just text — the seam that lets Shells, file transfer, and rich PresenceChannel exist later.\n...\n 102:\n*103:### 9.2 Instances (ADR-0003, as amended)\n 104:- **R-INST-1** Split identity: subnet-wide **endpoint ID** vs per-node **instance**. An instance is the *same* endpoint running **natively** on a machine.\n 105:- **R-INST-2** Per-node (anchored): files/project + harness session history. **Synced across instances:** the Psyche mind (two-tier — below).\n 106:- **R-INST-3** **Dormant (warm)** is the default resting state (session running, instant wake); **suspended (cold)** is opt-in (session closed, resume-on-wake) and can be triggered from any node. Registry status: active / dormant / suspended / offline.\n...\n 119:\n*120:### 9.3 Off-node reach-back\n 121:- **R-REACH-1** (v1) An agent can detect it is driven remotely (and from which node) and **transfer files** to/from the driving node.\n 122:- **R-REACH-2** (deferred) Remote command execution on the user's node — security-gated; workarounds exist via local agents.\n 123:\n...\n 125:\n*126:## 10. Networking & pairing\n 127:\n 128:- **R-NET-1** WAN messaging is first-class day-one, baked into the core crates behind a default-on `net` feature flag (ADR-0002): Iroh + mDNS LAN + pairing.\n 129:- **R-NET-2** v1 defaults to **n0.computer relays** (free, accountless) for zero-config WAN, with a **self-hostable-relay** config knob and plain-language disclosure.

The manifest is `traceable-reqs.toml` (seeded from PRD `R-*` + KNOWN-HAZARDS invariants). This contract makes the trace pay off instead of rotting.\n 4:\n*5:## Why\n 6:\n 7:The whole point of the rebuild is to *not* re-introduce the sister project's bugs and to ship the PRD's scope verifiably. A requirement that isn't traced to real evidence (a doc, an implementation, a test) is a requirement you're *hoping* is met. This contract converts that hope into a build that fails when evidence is missing.\n 8:\n*9:## The contract (rules)\n 10:\n 11:1. **The manifest is the authoritative requirement registry.** Every PRD `R-*` requirement and every KNOWN-HAZARDS invariant exists in `traceable-reqs.toml` as a `REQ-*` id. No work without a REQ; no REQ without intent to satisfy. The PRD holds the prose; the manifest holds the id + `required_stages`.\n 12:2. **Tag in the same change as the evidence.** When you write the function / test / doc-section that satisfies a stage, add its `[<stage>-><REQ-ID>]` tag in *that same commit*. Never \"tag later\" — this single rule is what stops the trace from drifting.\n...\n 18:\n*19:### Stages\n 20:\n 21:`doc` (prose/design/rustdoc) · `impl` (production code) · `unit` (unit test) · `int` (integration / e2e / cross-node).

A PR can't merge if it leaves an *activated* req's required stage uncovered. Runs alongside the DOCS-STRATEGY CI gates.\n 45:2. **Milestone activation gate.** Starting a milestone flips its reqs from `[]` to the real policy; the milestone **is not done until `check` is green for its reqs**.

Identity & session-binding\n 44:\n*45:### 2.1 Parent PID over ephemeral poll PID\n 46:- **Failure:** orphan check polls an ephemeral listener PID; it dies and is recycled (esp. Windows); a foreign process with the recycled PID reads as alive → false-positive teardown (or false-negative).\n 47:- **Invariant:** prefer the stable harness-session PID (`parent_pid`) over any ephemeral process PID for liveness; minimal `info.json` for supervisor-owned perches to avoid stale leaks.\n 48:- **spt-core mapping:** session binding (parent-process-tree anchor) still applies for harness-hosted topology.

The broker↔brain IPC and any brain-relaunch argv must be versioned and forward/backward tolerant (a newer brain talks to an older broker). This is the single most update-frequency-sensitive invariant.\n...\n 62:\n*63:### 2.4 Generation `gen_start` always = now() on cold-start AND handoff\n 64:- **Failure:** stale gen_start from a rehydrated state file fires time-based discriminators on the new process.\n 65:- **Invariant:** wall-clock `gen_start` is set to `now()` on both cold-start and handoff; generation counter increments on every start/revive; session UUID captured fresh and carried so the resumed mind distinguishes \"same gen continuing\" vs \"new gen born\".\n 66:- **spt-core mapping:** carries to the daemon's per-instance generation tracking.\n...\n 69:\n*70:### 2.5 Daemon-hosted endpoints have no dedicated liveness PID\n 71:- **Failure:** the sister evaluates Psyche/perch liveness via a dedicated process PID — the wrapper's own pid in `info.json`, checked with `is_process_alive`. Under ADR-0004 the Psyche (and any spt-hosted Self) is a **loop inside the daemon**, not a separate process: it holds no dedicated pid, and its `claude`/summarizer subprocess is ephemeral (spawned per pulse/commune, then exits). If a daemon-hosted perch's `info.json` carries the **daemon's** pid, then *every* hosted endpoint shares one pid, and `...\n 72:- **Invariant:** for **daemon-hosted** perches (Psyche; spt-hosted Self), liveness is the **daemon's authoritative in-memory endpoint table + a `status` field** on `info.json` (`online|offline|…`), **never** `is_process_alive(info.pid)`. `info.pid` for a daemon-hosted perch is at most a *hosted-by-daemon* marker (the daemon pid), not a liveness signal; registry stale-clean for these rows keys on the daemon's endpoint table, not per-row pid. This reuses the pattern already specified for **Shells** (`inf...\n 73:- **spt-core mapping:** the **M1/M2a interim** model keeps the Psyche/listener a real per-process owner (the `api listen` process), so its per-pid liveness (`deliver::is_online` → `info.read_pid` → `proc::is_process_alive`; `registry::clean_stale_entries`) is correct *interim*. **M3 daemon consolidation replaces it** with daemon-authoritative liveness for hosted perches.

A binary that dies **abruptly** (force-kill, crash, OOM) breaks no link, so nothing ever writes the flip: the record says `online` forever while the pid it names is gone. Every consumer of the recorded field then inherits the lie — `shell list` reports online indefinitely; `relink` (the one command that recover...\n 78:- **Invariant:** ONLINE-ness is **derived**, never the recorded field alone: `status == online` AND the recorded process identity is not *provably* gone. Missing/unparseable/zero PID or unavailable birth evidence fails toward alive; a positively mismatching native birth identifies a recycled PID as gone.

The original boot sweep fixed only machine reboots: it rejected corpses launched after machine boot, so a daemon-only restart still stranded every persistent shell.

The per-project tree lets any agent synthesize a broader context from *other* agents' contexts in the same project, and supports query-routing (\"which endpoint is most responsible for this task\"). *Mechanics (D6a):* the object DB is a **bare seed repo at `tracked/.seed.git`**; `agents/<id>/` and `projects/<project_id>/` are **linked worktr...\n 167:- **Two-tier sync maps onto the structure:** `agents/<id>/live-context.md` (the `a-` view) syncs to **all** instances of the endpoint; `projects/<project_id>/<id>/project-context.md` (the `p-` view) syncs only to instances sharing that project.\n...\n 169:\n*170:## BranchStore (git-KV) — generalizing the context store (ADR-0011)\n 171:\n 172:The context repo above is one instance of a general pattern: **a git branch used\n 173:as a versioned key/value filesystem** — write = one commit (tree = prev +\n...\n 209:\n*210:## Cross-node context sync\n 211:\n 212:**Single-writer invariant.** Each context file has exactly one logical writer — the owning agent's *active* instance (the active-instance-authoritative rule).

The PRD holds the prose; the manifest holds the id + `required_stages`.\n 12│2. **Tag in the same change as the evidence.** When you write the function / test / doc-section that satisfies a stage, add its `[<stage>-><REQ-ID>]` tag in *that same commit*.

Under ADR-0004 the Psyche (and any spt-hosted Self) is a **loop inside the daemon**, not a separate process: it holds no dedicated pid, and its `claude`/summarizer subprocess is ephemeral (spawned per pulse/commune, then exits). If a daemon-hosted perch's `info.json` carries the **daemon's** pid, then *every* hosted endpoint shares one pid, and `...\n  72│- **Invariant:** for **daemon-hosted** perches (Psyche; spt-hosted Self), liveness is the **daemon's authoritative in-memory endpoint table + a `status` field** on `info.json` (`online|offline|…`), **never** `is_process_alive(info.pid)`. `info.pid` for a daemon-hosted perch is at most a *hosted-by-daemon* marker (the daemon pid), not a liveness signal; registry stale-clean for these rows keys on the daemon's endpoint table, not per-row pid.

A binary that dies **abruptly** (force-kill, crash, OOM) breaks no link, so nothing ever writes the flip: the record says `online` forever while the pid it names is gone. Every consumer of the recorded field then inherits the lie — `shell list` reports online indefinitely; `relink` (the one command that recover...\n  78│- **Invariant:** ONLINE-ness is **derived**, never the recorded field alone: `status == online` AND the recorded process identity is not *provably* gone. Missing/unparseable/zero PID or unavailable birth evidence fails toward alive; a positively mismatching native birth identifies a recycled PID as gone.

The original boot sweep fixed only machine reboots: it rejected corpses launched after machine boot, so a daemon-only restart still stranded every persistent shell.

Several patterns are adapted from `BigscreenVR/pi-agent-memory` (credited inline).\n  4│\n *5│## Two-tier context\n  6│\n  7│- **live context** (per-agent, project-independent — the agent's *mind*): identity/persona, relationship + rapport with the user, the user's cross-project preferences & working style, cross-project life threads, **learnings from work that may apply to other projects**, a thin **project roster** (one line per project the agent works on), the agent's self-model. Synced to **all** instances of the endpoint.\n  8│- **project context** (per-agent-per-project — what the agent is doing *here*): codebase/architecture, decisions made here, **current focus / next steps / todos**, project conventions, build/test commands, blockers. Synced **only** to same-project instances.\n   │...\n 11│\n*12│### The discriminator (applied per *topic*, not per fragment)\n 13│\n 14│> **\"Would this still be true and relevant if the user opened a *different* project tomorrow?\"** Yes → live. No → project. Equivalently: **WHO the agent is** (live) vs **WHAT it's doing here** (project).\n 15│\n*16│### Anti-leak rules\n 17│\n 18│The observed failure is project detail leaking *into* live context (which then wrongly syncs everywhere). Countermeasures:\n 19│\n   │...\n 24│\n*25│### Boundary communes are Self-authored (resume Self, not echo)\n 26│\n 27│To get meaningful **live-context** updates on a consistent basis (the live signal is strong only from Self), three boundaries author their commune by **`--resume`-ing the Self session** (the actual agent), not by a background haiku echo:\n 28│\n   │...\n 34│\n*35│### `spt refresh` (spt-hosted self-service context refresh)\n 36│\n 37│A lever for an agent behind an **spt-hosted** endpoint to clear and resume itself without stalling. It: (1) triggers a `/clear` (which uses the **Self-resume-commune rule** above — consistent with all other boundaries), (2) thereby captures a commune, and (3) **guarantees a resume signal hits the harness post-clear** so the agent's turn restarts and it resumes work — starting from its immediate next-steps. Spt-hosted-only because the guarantee requires the daemon to own the PTY and inject the post-cl...\n 38│\n*39│### Ownership\n 40│\n 41│The live/project authoring directives are **core-owned** — fed to every Psyche by spt-core (part of the composed psyche-download the daemon writes to the turn's `{psyche_context_file}`), so the split is consistent across all adapters (inconsistent rules → sync chaos). Adapters add only harness mechanics (how to write the drop file).\n 42│\n*43│## memformat (deeply integrated, self-evolving, the split scaffold)\n 44│\n 45│memformat goes from a decorative, ignored seed to the **load-bearing schema that defines the two-tier context**. It makes the live/project decision **per-topic and rare** instead of per-fragment and constant — which is what makes the split stable.\n 46│\n   │...\n 51│\n*52│### Structured blocks (adapted from pi-agent-memory)\n 53│\n 54│A memformat topic is a tier-tagged **container of structured blocks**, not free-form prose. Each block:\n 55│\n 56│```\n*57│## <stable-block-id>\n 58│Concepts: <comma list>          # retrieval keys\n 59│Aliases: <comma list>           # retrieval synonyms (optional)\n 60│Applies to: <glob paths>        # sub-project scoping (optional)\n   │...\n 71│\n*72│## Retrieval Map (generated INDEX)\n 73│\n 74│A generated, lightweight **INDEX** over topics — summaries + concepts + aliases + paths — **not** a vector DB, **not** a full mirror (adapted from pi-agent-memory's Retrieval Map). One INDEX per **project** (aggregating all agents' project context → realizes cross-agent synthesis + query-routing: \"which endpoint owns this task\") and per **agent**. Regenerated on context change; the merge driver + INDEX regeneration keep it current.\n 75│\n*76│## Start-injection: dense working set, sparse tail\n 77│\n 78│The balance between immediate productivity and bounded context cost — tuned for SPT's **per-agent, work-fast** priority (vs pi's multi-agent-per-project digging, which is sparse-by-default):\n 79│\n   │...\n 84│\n*85│## Deferred\n 86│\n 87│- **Rebalance / Memory-Health pass** (later): the Psyche periodically (a) demotes leaked live→project content, and (b) — the deeper, pi-credited insight — verifies context is still *true vs the current code* (Memory Health), which requires investigating the codebase, so it's an autonomous-agent job, distinct from mechanical staleness (hash/INDEX mismatch).\n 88│- **Block-level OCC merge** (v1.x): the per-block `Hash:` (canonical content hash, excluding `Updated`/`Hash`) enables block-level, stale-aware cross-node merge — finer than the v1 whole-file newest-wins driver (`docs/STORAGE.md`). Recorded now (the block format carries `Hash:`), applied later.\n 89│\n*90│## Not adopted\n 91│\n 92│pi-agent-memory's **human-in-the-loop approval** (extract → review → approve, max-5-candidates) and **bash-mutation guardrails** fit its \"human curates\" philosophy. SPT's Psyche is **trusted to author its own mind autonomously** — so we adopt pi's *structure* (blocks, INDEX, bounded awareness, provenance, OCC) but **not** its approval gate. Controlled mutation is already covered by the drop-file single-writer rule (KNOWN-HAZARDS 6.4).\n### DOCS-STRATEGY.md#94CD\n  *1│# Documentation strategy\n   2│\n   3│> Draft (2026-05-31).

No file.\n 89:- **R-START-3** **spt-hosted:** daemon runs spawn-session into a broker PTY → binary `api bind` (or skips under commitment) → daemon delivers via manifest-configured method.

The manifest is `traceable-reqs.toml` (seeded from PRD `R-*` + KNOWN-HAZARDS invariants). This contract makes the trace pay off instead of rotting.\n 4:\n*5:## Why\n 6:\n 7:The whole point of the rebuild is to *not* re-introduce the sister project's bugs and to ship the PRD's scope verifiably. A requirement that isn't traced to real evidence (a doc, an implementation, a test) is a requirement you're *hoping* is met. This contract converts that hope into a build that fails when evidence is missing.\n 8:\n*9:## The contract (rules)\n 10:\n 11:1. **The manifest is the authoritative requirement registry.** Every PRD `R-*` requirement and every KNOWN-HAZARDS invariant exists in `traceable-reqs.toml` as a `REQ-*` id. No work without a REQ; no REQ without intent to satisfy. The PRD holds the prose; the manifest holds the id + `required_stages`.\n 12:2. **Tag in the same change as the evidence.** When you write the function / test / doc-section that satisfies a stage, add its `[<stage>-><REQ-ID>]` tag in *that same commit*. Never \"tag later\" — this single rule is what stops the trace from drifting.\n...\n 18:\n*19:### Stages\n 20:\n 21:`doc` (prose/design/rustdoc) · `impl` (production code) · `unit` (unit test) · `int` (integration / e2e / cross-node).

A PR can't merge if it leaves an *activated* req's required stage uncovered. Runs alongside the DOCS-STRATEGY CI gates.\n 45:2. **Milestone activation gate.** Starting a milestone flips its reqs from `[]` to the real policy; the milestone **is not done until `check` is green for its reqs**.

Race conditions & ordering\n 10:\n*11:### 1.1 Phantom INIT_SIGNOFF after grace period\n 12:- **Failure:** orphan teardown enqueues INIT_SIGNOFF before the grace-period recheck; a transient Self recovery (binary handoff, brief stale poll) makes the recheck pass-as-alive, but the signoff was already spooled and drains on the next iteration → teardown despite a live Self.\n 13:- **Invariant:** grace-period wait MUST complete *before* composing/delivering INIT_SIGNOFF; the recheck must bind `still_gone` before any envelope write.\n 14:- **spt-core mapping:** in-daemon now (no separate wrapper), but the ordering invariant is identical — orphan/teardown logic must re-evaluate liveness after the grace wait, not before enqueue.\n...\n 16:\n*17:### 1.2 Poll-rewrite race & info.json mid-write reads\n 18:- **Failure:** `info.json` written by the wrapper mid-iteration while a list/classify command reads it → torn read, misclassification.\n 19:- **Invariant:** consult liveness via the supervisor (`is_wrapper_alive`-equivalent) before any grace gate; reads of state files must tolerate concurrent writes (atomic write + rename, or read-retry).\n 20:- **spt-core mapping:** the daemon owns both writer and reader → use in-process locking/snapshotting instead of racing on disk. Cross-node registry reads remain eventually-consistent and must tolerate staleness.\n...\n 22:\n*23:### 1.3 Stale `index.lock` wedge from prior git crash\n 24:- **Failure:** crashed git leaves a 0-byte `index.lock` in a psyche tracked worktree; every later commit blocks forever.\n 25:- **Invariant:** on daemon boot, sweep seed + all agent/project worktrees for stale locks (0 bytes, mtime > 60s) and remove; leave live locks alone.\n 26:- **spt-core mapping:** cross-node Psyche sync (ADR-0002/0003) replaces git-repo sync, so the *git* lock may disappear — but any equivalent lockfile in the new sync mechanism needs the same stale-sweep on boot.\n...\n 28:\n*29:### 1.4 Deferred spool rows must not leak to the event stream\n 30:- **Failure:** a hook spools a deferred (spool-only, no TCP wake) notice; startup `drain_all` flushes ALL rows including deferred → event emitted at wrong time/priority.\n 31:- **Invariant:** startup drain (and idle/timeout TCP-wake sites) use `drain_non_deferred` only; deferred rows are picked up by their intended consumer via `peek`. All drain sites must agree on which rows they flush.\n 32:- **spt-core mapping:** carries directly — the daemon's spool-drain has the same deferred-vs-immediate distinction.\n...\n 34:\n*35:### 1.5 Worker (working-perch) lifecycle path consistency\n 36:- **Failure:** subagent-start creates the perch at one path layout; later hooks read it at another → not found; stop-hook scan misses nested perches.\n 37:- **Invariant:** all Worker/Psyche child-perch path composition routes through one central resolver; no divergent path construction across hooks.\n 38:- **spt-core mapping:** `Worker` is a day-one endpoint type; the daemon owns the registry, so perch location is a registry lookup, not ad-hoc path math. Single source of truth for instance→location.\n...\n 42:\n*43:## 2. Identity & session-binding\n 44:\n*45:### 2.1 Parent PID over ephemeral poll PID\n 46:- **Failure:** orphan check polls an ephemeral listener PID; it dies and is recycled (esp. Windows); a foreign process with the recycled PID reads as alive → false-positive teardown (or false-negative).\n 47:- **Invariant:** prefer the stable harness-session PID (`parent_pid`) over any ephemeral process PID for liveness; minimal `info.json` for supervisor-owned perches to avoid stale leaks.\n 48:- **spt-core mapping:** session binding (parent-process-tree anchor) still applies for harness-hosted topology. For spt-hosted sessions the broker holds the child directly → liveness is the broker's held-handle state, more reliable than PID polling.\n...\n 50:\n*51:### 2.2 Stdin session_id precedence over env\n 52:- **Failure:** subagent inherits a stale `OWL_SESSION_ID` env across `/clear`; hook gets two session_ids (fresh stdin, stale env) → wrong-agent binding.\n 53:- **Invariant:** stdin-provided session_id wins; env is fallback only.\n 54:- **spt-core mapping:** the harness-contract subcommand surface must define the same precedence for whatever identity fields hooks pass in.\n...\n 56:\n*57:### 2.3 Binary-handoff argv schema must stay backward-compatible\n 58:- **Failure:** old binary spawns new binary with old argv arity; clap rejects before state rehydration → wrapper dies unlogged.\n 59:- **Invariant:** every newly-added handoff positional has a default; state-file rehydration happens *after* argv parse; defaults survive intermediate versions.\n 60:- **spt-core mapping:** CRITICAL — self-update (ADR-0004) makes handoff routine. The broker↔brain IPC and any brain-relaunch argv must be versioned and forward/backward tolerant (a newer brain talks to an older broker). This is the single most update-frequency-sensitive invariant.\n...\n 62:\n*63:### 2.4 Generation `gen_start` always = now() on cold-start AND handoff\n 64:- **Failure:** stale gen_start from a rehydrated state file fires time-based discriminators on the new process.\n 65:- **Invariant:** wall-clock `gen_start` is set to `now()` on both cold-start and handoff; generation counter increments on every start/revive; session UUID captured fresh and carried so the resumed mind distinguishes \"same gen continuing\" vs \"new gen born\".\n 66:- **spt-core mapping:** carries to the daemon's per-instance generation tracking.\n...\n 69:\n*70:### 2.5 Daemon-hosted endpoints have no dedicated liveness PID\n 71:- **Failure:** the sister evaluates Psyche/perch liveness via a dedicated process PID — the wrapper's own pid in `info.json`, checked with `is_process_alive`. Under ADR-0004 the Psyche (and any spt-hosted Self) is a **loop inside the daemon**, not a separate process: it holds no dedicated pid, and its `claude`/summarizer subprocess is ephemeral (spawned per pulse/commune, then exits). If a daemon-hosted perch's `info.json` carries the **daemon's** pid, then *every* hosted endpoint shares one pid, and `...\n 72:- **Invariant:** for **daemon-hosted** perches (Psyche; spt-hosted Self), liveness is the **daemon's authoritative in-memory endpoint table + a `status` field** on `info.json` (`online|offline|…`), **never** `is_process_alive(info.pid)`. `info.pid` for a daemon-hosted perch is at most a *hosted-by-daemon* marker (the daemon pid), not a liveness signal; registry stale-clean for these rows keys on the daemon's endpoint table, not per-row pid. This reuses the pattern already specified for **Shells** (`inf...\n 73:- **spt-core mapping:** the **M1/M2a interim** model keeps the Psyche/listener a real per-process owner (the `api listen` process), so its per-pid liveness (`deliver::is_online` → `info.read_pid` → `proc::is_process_alive`; `registry::clean_stale_entries`) is correct *interim*. **M3 daemon consolidation replaces it** with daemon-authoritative liveness for hosted perches. Keep the liveness check behind one resolver (mirrors `resolve_address` stale-clean) so the M3 swap is localized — do **not** let ...\n...\n 75:\n*76:### 2.6 A shell instance's `online` is a recorded field with no death edge\n 77:- **Failure:** a shell perch's `status` has exactly two writers — the bind handshake (→`online`) and `close_shell` (→`offline`) — and `close_shell` runs on the **link-break** path alone. A binary that dies **abruptly** (force-kill, crash, OOM) breaks no link, so nothing ever writes the flip: the record says `online` forever while the pid it names is gone. Every consumer of the recorded field then inherits the lie — `shell list` reports online indefinitely; `relink` (the one command that recover...\n 78:- **Invariant:** ONLINE-ness is **derived**, never the recorded field alone: `status == online` AND the recorded process identity is not *provably* gone. Missing/unparseable/zero PID or unavailable birth evidence fails toward alive; a positively mismatching native birth identifies a recycled PID as gone. Derivation never promotes a recorded-offline instance.

The original boot sweep fixed only machine reboots: it rejected corpses launched after machine boot, so a daemon-only restart still stranded every persistent shell. The measured releases#287 specimen launched at machine boot +46s and stayed down for 27 hours after a daemon restart despite its owner being online.\n 88:- **The owner-facing surfaces HIDE the fault**, which is why it survived unreported for days: every display path (`shell list`, its `--json` twin, the shell-context render) routes through the ONE discovery seam, which **derives** status (2.6) and so correctly reports the binary as offline — while the only consumer whose decision matters, the wake cascade, reads the RECORDED field that no owner-facing surface shows. Absence of a visible symptom is therefore **not** evidence of absence of this fault, and...\n 89:- **The existing cascade test cannot fail on it — its SETUP SUPPRESSES THE FAILING ARM.** `rest_edges_cascade_shells_with_divergence` establishes its fixture by driving the suspend path, which itself writes the `offline` the code under test is supposed to encounter — so the restart shape (a record still saying `online` over a corpse, reached with **no** suspend edge) is unreachable from that fixture BY CONSTRUCTION.

Lifecycle\n 100:\n*101:### 3.1 Ephemeral perch cleanup on every `ring` exit path\n 102:- **Failure:** `ring` creates an ephemeral perch; early-exit paths (no-perch, empty-msg, timeout) skip cleanup → stale dirs accumulate.\n 103:- **Invariant:** every code path that creates an ephemeral perch cleans it before exit; exception: if the caller already had an active perch, do not treat as ephemeral and do not clean up.\n 104:- **spt-core mapping:** `ring` semantics carry; the daemon owns ephemeral-perch lifecycle, so a single guaranteed-cleanup (drop guard / RAII) is achievable in-process.\n...\n 106:\n*107:### 3.2 Stale signoff sentinel must not kill a fresh start\n 108:- **Failure:** a leftover `.claude/<id>-signoff.md` from a prior session is read by a fresh listener as a live signoff → immediate teardown.\n 109:- **Invariant:** on every listener/daemon spawn, sweep stale signoff sentinels; signoff files are write-once per generation.\n 110:- **spt-core mapping:** same sweep on daemon (re)start per hosted instance.\n...\n 112:\n*113:### 3.3 Orphan teardown fires echo-commune BEFORE INIT_SIGNOFF\n 114:- **Failure:** teardown delivers INIT_SIGNOFF without first saving the final context delta → Psyche signoff lacks the context-save summary.\n 115:- **Invariant:** on orphan path, synchronously run the echo-commune (final delta) before composing INIT_SIGNOFF; skip only if the session_id is missing.\n 116:- **spt-core mapping:** the daemon runs psyche/pulse loops in-process; ordering invariant identical.\n...\n 118:\n*119:### 3.4 A `ring` never adopts — so never deletes — a perch it did not create\n 120:- **Failure:** 3.1 guards the LEAK direction (cleanup on every exit path). It says nothing about *whose* perch is being cleaned, and the two compose into a data-loss bug: `ring` decides \"the caller has no perch\" **ready-marker-first**, so an existing perch whose marker is momentarily down — busy turn, soft session-end, stale re-bind — reads *perchless*, `setup_ephemeral` clobbers the caller's real `info.json`, and 3.1's guaranteed cleanup then runs on the way out and **deletes** the ready marker, `in...\n 121:- **The mail half is a CONFIDENTIALITY failure, not only a durability one:** deletion is what happens on the way out, but while the ring *holds* the adopted perch its reply-wait `drain_one_at` consumes whatever is in the victim's spool and **renders it to the ringer as the reply**. Ringer == victim (the field case) is the degenerate, mild shape — anything drained reaches its intended recipient. Ringer != victim is the severe one: a third party rings a live agent and the **victim's inbox is drained into...\n 122:- **Self-camouflaging**, which is why it went unattributed for hours: the damage — perch gone, roster row ghosted — *mimics the stale-liveness condition people reach for `ring` to diagnose*. The field caller was probing a ghost-roster symptom and the probe manufactured a fresh one, so debuggers of stale liveness are disproportionately its victims and read the wreckage as more of the symptom they were chasing.\n### STORAGE.md#2B1D\n*1:# $SPT_HOME on-disk layout\n 2:\n 3:> Draft design doc (2026-05-30).

One dir to back up, move, or repackage for a marketplace/handheld. No XDG three-way split.\n 8:2. **Endpoint IDs are adapter-agnostic.** `ling` can run under `claude-spt`, then later under `spt-codex` or `spt-pi`. Perches and context key on bare `endpoint_id`; the currently-running `adapter_name` is a *property of the instance* recorded in `info.json`, never a path segment. **At most one instance of an ID per node** — a second attempt (any adapter) is rejected.\n...\n 12:\n*13:## Layout\n 14:\n 15:```\n 16:$SPT_HOME/\n...\n 60:\n*61:### The contact ledger — `identity/trust/contacts.json` (DOORBELL W3)\n 62:\n 63:<!-- [doc->REQ-UNLISTED-CONTACT-LEDGER] -->\n 64:\n...\n 98:\n*99:### Registry snapshots + the resource-advertisement blurb (D9)\n 100:\n 101:<!-- [doc->REQ-INST-14] -->\n 102:\n...\n 119:\n*120:## serve/registry — authoritative serving assignments\n 121:\n 122:<!-- [doc->REQ-WEB-SERVING-REGISTRY] -->\n 123:\n...\n 163:\n*164:## tracked/ — the context git repo\n 165:\n 166:- A local **git repository** (carried forward from modern SPT's mechanism). Two branch views: **`a-<endpoint_id>`** (per-agent) and **`p-<project_id>`** (per-project). The per-project tree lets any agent synthesize a broader context from *other* agents' contexts in the same project, and supports query-routing (\"which endpoint is most responsible for this task\"). *Mechanics (D6a):* the object DB is a **bare seed repo at `tracked/.seed.git`**; `agents/<id>/` and `projects/<project_id>/` are **linked worktr...\n 167:- **Two-tier sync maps onto the structure:** `agents/<id>/live-context.md` (the `a-` view) syncs to **all** instances of the endpoint; `projects/<project_id>/<id>/project-context.md` (the `p-` view) syncs only to instances sharing that project.\n...\n 169:\n*170:## BranchStore (git-KV) — generalizing the context store (ADR-0011)\n 171:\n 172:The context repo above is one instance of a general pattern: **a git branch used\n 173:as a versioned key/value filesystem** — write = one commit (tree = prev +\n...\n 209:\n*210:## Cross-node context sync\n 211:\n 212:**Single-writer invariant.** Each context file has exactly one logical writer — the owning agent's *active* instance (the active-instance-authoritative rule). Two nodes never legitimately write the same file simultaneously, so sync is mostly **propagation**, and disjoint files (node A has `agents/ling`, node B has `agents/momo`) simply **union**.\n 213:\n...\n 234:\n*235:## Worktree portability\n 236:\n 237:The `a-<id>` / `p-<project_id>` branch views are **linked git worktrees** off the bare seed repo. Linked worktrees store **absolute** back-links by default (`/home/<user>/…`, `C:\\Users\\<user>\\…`) → break on relocation, a different user account, or migration. Use **relative worktree paths** (`git config worktree.useRelativePaths true`, Git ≥ 2.48) so `tracked/` is relocatable. **Fallback** for older git: spt-core runs `git worktree repair` after any relocation to re-point links locally (spt-core d...\n 238:\n*239:## project_id\n 240:\n 241:Derived **from the git remote URL** of the project if it has one (stable + path-independent, so the *same* project at different absolute paths on different machines — `/home/x/proj` vs `C:\\Users\\x\\proj` — resolves to the *same* `project_id`, which is what makes project-context sync match across instances).

Anything spt-core owns (sentinels, spool/registry/perch schemas, the event-block vocabulary, the version-trampoline mechanism, config knobs) is **not** in the manifest.\n 8:\n*9:## What is NOT in the manifest (spt-core-owned)\n 10:\n 11:- **Sentinels** (`.idle`-equiv, echo-gate) — managed by `api state`/`api echo-gate`; the adapter only *calls* them.\n 12:- **Spool / registry / perch `info.json` / daemon-state schemas** — core.\n...\n 21:\n*22:## Manifest sections\n 23:\n*24:### `[adapter]` — header\n 25:```toml\n 26:[adapter]\n 27:name = \"claude-spt\"\n...\n 118:\n*119:### `[hooks.<event>]` — inbound hook table\n 120:Per harness event: the `api` command it fires, the stdin fields it maps in, and its **output capability** — `can_inject` (whether this hook can surface context to the agent).
