Cuts token usage ~75% by dropping filler, articles, and pleasantries while keeping full technical accuracy. Use when user says \"caveman mode\", \"talk like caveman\", \"use caveman\", \"less tokens\", \"be brief\", or invokes /caveman.\n\n- code-review: Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/spec asked for?). Runs both reviews in parallel sub-agents and reports them side by side. 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\nAdvance the remaining v0.69 bugfix queue while PR #216 owns both CI runners. Parent todlando implements #292 and integrates evidence; these tasks are independent.\n# Constraints\nSkip ALL validation: no Cargo, builds, formatters, linters, tests, services, or production restarts. No push. Each lane is under .worktrees/ in this repo. Follow supplied AGENTS rules, traceable requirements, existing conventions. Commit trailers exactly `Co-authored by: todlando`. Read required orientation by relevant sections. No source-text tests. Findings must be evidence-backed, not speculative. Reviewer work is read-only.\n# Contract\nShellRestore exclusively owns .worktrees/287-shellrestore (branch fix/287-persistent-restore at de5a44bc). Churn reviewers only read .worktrees/286-churn, head 19a9097956de0db898eaeb3a7dc4765189ade874; neither edits it. Review base de5a44bc338d679f3c63f6d0f68826eb9e575d73 is verified and diff nonempty: 5 files, 425 insertions/56 deletions, single commit `19a90979 fix(daemon): bound healthy connection stderr and retain livehost polls`. Diff command in that cwd: `git diff de5a44bc...HEAD`. Issue spec is issue://BigscreenVR/spt-bs-releases/286. Parent's measured scope: healthy lifecycle lines dominate log volume; livehost query reconnects every5s; family gate is already once per real bind and is EXONERATED, no binder policy changes. Keep reviewer axes separate.\nStandards smell baseline (heuristics only, repo rules override): Mysterious Name—unclear purpose, rename; Duplicated Code—same logic repeated, share; Feature Envy—method uses another object's data more than its own, relocate; Data Clumps—same fields travel together, consider cohesive type; Primitive Obsession—primitive encoding deserves a domain type; Repeated Switches—duplicated dispatch choices, share one map/interface; Shotgun Surgery—one change scattered, gather; Divergent Change—one module changes for unrelated reasons, separate; Speculative Generality—unused abstraction or hooks, remove; Message Chains—caller walks internals, hide walk; Middle Man—pure forwarding without value, remove; Refused Bequest—subtype rejects parent contract, use composition. Cite smells as judgement calls, not hard violations. Skip tooling-enforced findings.\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 `ShellRestore`. Currently visible peers:\n- `ChurnSpec` — reviewer (sub, running)\n- `ChurnStandards` — reviewer (sub, running)\n- `Main` — main (main, running)\n2 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.

Loop the trigger 100×, parallelise, add stress, narrow timing windows, inject sleeps. A 50%-flake bug is debuggable; 1% is not — keep raising the rate until it's debuggable.\n\n### When you genuinely cannot build a loop\n\nStop and say so explicitly. List what you tried. Ask the user for: (a) access to whatever environment reproduces it, (b) a captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.\n\nDo not proceed to Phase 2 until you have a loop you believe in.\n\n## Phase 2 — Reproduce\n\nRun the loop.

Wrong bug = wrong fix.\n- [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).\n- [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.\n\nDo not proceed until you reproduce the bug.\n\n## Phase 3 — Hypothesise\n\nGenerate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.\n\nEach hypothesis must be **falsifiable**: state the prediction it makes.\n\n> Format: \"If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse.\"\n\nIf you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.\n\n**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly (\"we just deployed a change to #3\"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it — proceed with your ranking if the user is AFK.\n\n## Phase 4 — Instrument\n\nEach probe must map to a specific prediction from Phase 3. **Change one variable at a time.**\n\nTool preference:\n\n1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.\n2. **Targeted logs** at the boundaries that distinguish hypotheses.\n3. Never \"log everything and grep\".\n\n**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep.

Clean-room rebuild of `claude_skill_owl`.\n4:\n5:**Orientation — read before working:** `PRD.md` (requirements), `ROADMAP.md` (build path), `CONTEXT.md` (glossary/model, authoritative for meaning), `docs/adr/` (decisions), `docs/KNOWN-HAZARDS.md` (invariants we must not re-break), `docs/{STORAGE,MANIFEST,CONTEXT-MEMORY,DOCS-STRATEGY,TRACEABILITY}.md`.\n6:\n7:For maintainer/debug update work, also read `docs/DEBUG-ROLLOUT.md` before touching the update-set or rollout path.\n8:\n9:For work needing Linux tests and proof, this machine is authorized to ssh into a Linux box: `reavus@kitsubito`\n10:\n11:IMPORTANT: All agents you work alongside run on spt-core itself — the legacy-SPT (`$OWL`/`$LIVE`) era ended with the 2026-07 fleet migration; those commands are gone. Reach other agents with `spt send` (or the `/sptc:send` skill); keep message bodies short, and send long bodies from a file rather than inline. Everything else can be learned from the corresponding `/sptc:` skill doc.\n12:\n13:## Requirement traceability (binding)\n14:\n15:This project uses `traceable-reqs` (`traceable-reqs.toml` = the authoritative `REQ-*` registry). The full contract is `docs/TRACEABILITY.md`. The rules you must follow:\n16:\n17:1. **Tag evidence in the same change.** When you write a function/test/doc-section that satisfies a requirement stage, add its tag in that same commit:\n18:   `// [impl->REQ-FOO]` · `// [unit->REQ-FOO]` · `<!-- [doc->REQ-FOO] -->`\n19:   Stages: `doc` / `impl` / `unit` / `int`. Tag *on or immediately above* the real evidence — never at file tops to satisfy coverage.\n20:2. **Run `traceable-reqs check` before declaring work done.** Exit-1 means missing/invalid evidence — fix it, don't ship it.\n21:3. **New requirement → add it to `traceable-reqs.toml` first** (with a `REQ-*` id), then satisfy it. No untracked work; no untagged evidence.\n22:4. **KNOWN-HAZARDS are `REQ-HAZARD-*` requirements** — each needs a test before it's \"covered.\" Treat the hazard list as a conformance checklist you must satisfy, not advice.\n23:5. **Activate, don't pre-fail.** Requirements you aren't yet working stay `required_stages = []`. Activate (set real stages) only when starting the milestone that delivers them.\n24:\n25:## Issue tracking (unique case)\n26:\n27:Codebase issues are maintained on **`BigscreenVR/spt-bs-releases`** — the less-private *releases* repo — NOT on `spt-bs-core` where the code lives. This is a deliberate exception (operator-ruled 2026-07-27): file, triage, and reference issues against `spt-bs-releases`.\n28:\n29:Requests and milestones are tracked through the **alchemy shell** (`alchemy-0`, the Requests shell bound to `spt-bs-releases`) on top of those GitHub issues. The label taxonomy is the workflow: `state:` BACKLOG → EVAL → GREENLIT → WIP → ACCEPTANCE → DONE (plus CUT / SHELVED), `type:` BUGFIX / ADDITION / CHANGE, `flag: NEEDS-OPERATOR`, and per-node `kind: SPT-TRACKING` pins (marked DO NOT DELETE — leave them alone).\n30:\n31:## Other conventions\n32:\n33:- Match surrounding code style; copy-verbatim the sister project's stable wire/schema formats (ADR-0001), clean-room everything else.\n34:- Honor every `docs/KNOWN-HAZARDS.md` invariant — these are real bugs already paid for once.\n35:- Docs are dual-audience (human + AI dev-agent) per `docs/DOCS-STRATEGY.md`; doc generation is CI-gated against drift.\n36:- Commit messages end with the project's co-author trailer, exact spelling `Co-authored by: <your live agent name>` (e.g. `Co-authored by: todlando`) — NOT git's hyphenated `Co-Authored-By:`; CI's runner-informant parses only the space spelling for attribution.\n37:  - **Audit this trailer with `git log --grep` or a raw body read, NEVER `%(trailers:)`** (nor `interpret-trailers --parse`): git's trailer tokenizer requires a whitespace-free token, so the space spelling is structurally invisible to it and every trailer query returns a confident EMPTY on every commit — a clean zero that reads as total attribution loss. Measured 2026-07-30 (main @`8f3e10b`, Signed-off-by and hyphenated-key controls both parse); re-derived at full cost 2026-08-03 by one of its own original measurers, which is why this sentence lives here at the mandate rather than in a document you must decide to open.\n38:- **Worktrees (binding, operator-ruled 2026-07-05):** every `git worktree` (gate rigs, agent scratch, anything) goes under `.worktrees/` in THIS project's root (`.gitignore`d) — e.g. `git worktree add --detach .worktrees/gate-<sha> <sha>`. NEVER create worktrees as siblings of the project dir; stray sibling folders accumulate orphan-pinned skeletons and pollute `~/Documents/projects`. Remove yours when done (`git worktree remove` + prune; retry later if a handle pins it).\n39:<!-- [doc->REQ-POOL-FOREIGN-TREE-REFUSED] -->\n40:- **Build-cache pools (binding, releases#103):** a cargo `target/` directory belongs to ONE source tree. Two trees building into one pool overwrite each other's artifacts and fabricate reds that belong to neither — the v0.51.0 W1/H1 `E0308` that vanished on re-run. **The rule is about the RELATIONSHIP, not the path:** a junction and a `CARGO_TARGET_DIR` env var reach the same hazard, and the env var leaves no directory entry to notice afterwards, so \"is this dir under `.worktrees/`\" never was the question.

Rust crates + a single `spt` binary. Clean-room rebuild of `claude_skill_owl`.\r\n\r\n**Orientation — read before working:** `PRD.md` (requirements), `ROADMAP.md` (build path), `CONTEXT.md` (glossary/model, authoritative for meaning), `docs/adr/` (decisions), `docs/KNOWN-HAZARDS.md` (invariants we must not re-break), `docs/{STORAGE,MANIFEST,CONTEXT-MEMORY,DOCS-STRATEGY,TRACEABILITY}.md`.\r\n\r\nFor maintainer/debug update work, also read `docs/DEBUG-ROLLOUT.md` before touching the update-set or rollout path.\r\n\r\nFor work needing Linux tests and proof, this machine is authorized to ssh into a Linux box: `reavus@kitsubito`\r\n\r\nIMPORTANT: All agents you work alongside run on spt-core itself — the legacy-SPT (`$OWL`/`$LIVE`) era ended with the 2026-07 fleet migration; those commands are gone. Reach other agents with `spt send` (or the `/sptc:send` skill); keep message bodies short, and send long bodies from a file rather than inline. Everything else can be learned from the corresponding `/sptc:` skill doc.\r\n\r\n## Requirement traceability (binding)\r\n\r\nThis project uses `traceable-reqs` (`traceable-reqs.toml` = the authoritative `REQ-*` registry). The full contract is `docs/TRACEABILITY.md`. The rules you must follow:\r\n\r\n1. **Tag evidence in the same change.** When you write a function/test/doc-section that satisfies a requirement stage, add its tag in that same commit:\r\n   `// [impl->REQ-FOO]` · `// [unit->REQ-FOO]` · `<!-- [doc->REQ-FOO] -->`\r\n   Stages: `doc` / `impl` / `unit` / `int`. Tag *on or immediately above* the real evidence — never at file tops to satisfy coverage.\r\n2. **Run `traceable-reqs check` before declaring work done.** Exit-1 means missing/invalid evidence — fix it, don't ship it.\r\n3. **New requirement → add it to `traceable-reqs.toml` first** (with a `REQ-*` id), then satisfy it. No untracked work; no untagged evidence.\r\n4. **KNOWN-HAZARDS are `REQ-HAZARD-*` requirements** — each needs a test before it's \"covered.\" Treat the hazard list as a conformance checklist you must satisfy, not advice.\r\n5. **Activate, don't pre-fail.** Requirements you aren't yet working stay `required_stages = []`. Activate (set real stages) only when starting the milestone that delivers them.\r\n\r\n## Issue tracking (unique case)\r\n\r\nCodebase issues are maintained on **`BigscreenVR/spt-bs-releases`** — the less-private *releases* repo — NOT on `spt-bs-core` where the code lives. This is a deliberate exception (operator-ruled 2026-07-27): file, triage, and reference issues against `spt-bs-releases`.\r\n\r\nRequests and milestones are tracked through the **alchemy shell** (`alchemy-0`, the Requests shell bound to `spt-bs-releases`) on top of those GitHub issues. The label taxonomy is the workflow: `state:` BACKLOG → EVAL → GREENLIT → WIP → ACCEPTANCE → DONE (plus CUT / SHELVED), `type:` BUGFIX / ADDITION / CHANGE, `flag: NEEDS-OPERATOR`, and per-node `kind: SPT-TRACKING` pins (marked DO NOT DELETE — leave them alone).\r\n\r\n## Other conventions\r\n\r\n- Match surrounding code style; copy-verbatim the sister project's stable wire/schema formats (ADR-0001), clean-room everything else.\r\n- Honor every `docs/KNOWN-HAZARDS.md` invariant — these are real bugs already paid for once.\r\n- Docs are dual-audience (human + AI dev-agent) per `docs/DOCS-STRATEGY.md`; doc generation is CI-gated against drift.\r\n- Commit messages end with the project's co-author trailer, exact spelling `Co-authored by: <your live agent name>` (e.g. `Co-authored by: todlando`) — NOT git's hyphenated `Co-Authored-By:`; CI's runner-informant parses only the space spelling for attribution.\r\n  - **Audit this trailer with `git log --grep` or a raw body read, NEVER `%(trailers:)`** (nor `interpret-trailers --parse`): git's trailer tokenizer requires a whitespace-free token, so the space spelling is structurally invisible to it and every trailer query returns a confident EMPTY on every commit — a clean zero that reads as total attribution loss. Measured 2026-07-30 (main @`8f3e10b`, Signed-off-by and hyphenated-key controls both parse); re-derived at full cost 2026-08-03 by one of its own original measurers, which is why this sentence lives here at the mandate rather than in a document you must decide to open.\r\n- **Worktrees (binding, operator-ruled 2026-07-05):** every `git worktree` (gate rigs, agent scratch, anything) goes under `.worktrees/` in THIS project's root (`.gitignore`d) — e.g. `git worktree add --detach .worktrees/gate-<sha> <sha>`. NEVER create worktrees as siblings of the project dir; stray sibling folders accumulate orphan-pinned skeletons and pollute `~/Documents/projects`. Remove yours when done (`git worktree remove` + prune; retry later if a handle pins it).\r\n<!-- [doc->REQ-POOL-FOREIGN-TREE-REFUSED] -->\r\n- **Build-cache pools (binding, releases#103):** a cargo `target/` directory belongs to ONE source tree. Two trees building into one pool overwrite each other's artifacts and fabricate reds that belong to neither — the v0.51.0 W1/H1 `E0308` that vanished on re-run. **The rule is about the RELATIONSHIP, not the path:** a junction and a `CARGO_TARGET_DIR` env var reach the same hazard, and the env var leaves no directory entry to notice afterwards, so \"is this dir under `.worktrees/`\" never was the question. A build script enforces it (`crates/spt-store/build.rs`) and refuses with `SPT_POOL_FOREIGN`. **Sharing a pool SEQUENTIALLY is fine and expected** — a finished lane is taken over loudly, not refused; only a LIVE lane blocks you. Claim a pool at lane start …\n- **Target-tree teardown (releases#103, same lane):** never delete a `target/` you have not classified.

Reap the target SUBTREE, never a session or worktree directory around it. Do not point `CARGO_TARGET_DIR` into a scratchpad (v0.50.0 incident) or at another checkout's target (H1 incident).\r\n- **CI / merge strategy:** golden CI (ADR-0050, ruled 2026-07-27) — milestone-batch golden runs, thin-lane PRs, ff-only main (tested sha == merged sha).

No error anywhere. The operator noticed 27 hours later because doyle's pacer had stopped pacing. `shell list` read `offline` the whole time, which is correct, and nothing ever relaunched.\n\n## Mechanism (measured 2026-09-08 10:26Z, spt-core 0.67.0, log `daemon.stderr.log` generation 0 / pid 48232)\n\n- Machine boot: 2026-09-04 08:02:53Z. Pacer launched by that boot's sweep: 2026-09-04 08:03:39Z (`shell.launch.json launched_ms=1788509019651`, native start stamp agrees).\n- Daemon restarted (no machine reboot): 2026-09-07 08:03:20Z. The pacer process (pid 27656) died with it. The heal fired: `SHELL_RECORD_HEALED:doyle/PACER-0: online -> offline` (8 such lines, one per persistent instance).\n- The restore never fired: zero `SHELL_BOOT_RESTORED` / `SHELL_OWNER_ONLINE_RESTORED` lines in the whole generation. The previous generation (boot 2026-09-04) shows `SHELL_BOOT_RESTORED:doyle/alchemy-0` etc.\n- Cause: `launch_predates_boot(launched_ms, boot_ms, slack)` in `spt_daemon::shellwake` compares against the MACHINE boot instant (`boot_instant_ms` = now minus `GetTickCount64`). A launch at boot+46 s does not predate that boot, so every daemon-only restart lands in the \"force-killed THIS boot => NOT eligible\" arm on all three triggers (boot sweep, owner-online edge, watcher). By construction, a daemon restart is indistinguishable from an operator force-kill under this discriminant.\n- doyle/alchemy-0 came back only because `spt shell cmd` wakes an offline persistent instance on demand (linkhost `wake_if_offline_persistent`); PACER receives no owner commands, so it stays down until a human runs `relink`. Confirmed: `spt shell relink PACER-0` at 10:28:39Z brought it online (pid 45088), status reply received.\n\n## Why this matters\n\nA daemon restart happens on every self-update. KNOWN-HAZARDS 2.7 (`REQ-HAZARD-RESTART-STRANDS-PERSISTENT-SHELLS`) states \"a node restart must not strand a persistent instance\" and was closed for the machine-reboot face; the daemon-restart face reproduces the same stranding through the discriminant that closed it. The contract sentence (a persistent shell is online whenever its owner is) is false after every update.\n\n## Shape question for the fix (not ruled here)\n\nThe force-kill freeze (releases#78 leg (c)) must survive. Candidate: evaluate the corpse against the DAEMON generation instant as well as the machine boot instant, i.e. a corpse whose launch predates the current daemon start is a restart casualty. The open edge: a shell that survives a daemon restart and is then force-killed would have a launch older than the daemon start and would be relaunched. Whether any shell survives a restart (broker-hosted ones die with the broker; relay ones close on link-break) needs measuring before the rule is set.\n\n## Evidence\n\n- `C:\\Users\\decid\\AppData\\Local\\spt-core\\logs\\daemon.stderr.log` lines 64-119 (heals), no RESTORED lines.\n- `owlery/doyle/shells/PACER-0/{shell.pid,shell.launch.json,info.json}`.\n- perri/PACER-0 (pid 28464) and todlando/PACER-0 (pid 42736) still offline at filing; their owners must relink or issue a shell cmd.\n\n## Comments (2)\n\n### @SaberMage · 2026-09-08T10:31:53Z\n\nTwo riders from perri (2026-09-08 10:31Z), after relinking her three stranded shells:\n\n1. **Enumerate every stranded shell per owner.** The daemon log carried `SHELL_RECORD_HEALED` for perri/PACER-0, perri/alchemy-0 AND perri/alchemy-1 (lines 94, 103, 105 of the generation-0 log); my notice to her named only PACER-0.

Measured on my own relink at 10:28:39Z (pid 45088, online within 6 s). The token is honest about the bind handshake but the word `offline` on a success line is the part a reader keeps.

Such shells must come online anytime the endpoint comes online, end of story.\n\nConsequences for the fix (doyle's reading of the ruling, to be built as stated):\n\n1. For a `persistent = true` instance, the owner-online edge and the boot sweep relaunch it whenever the owner endpoint is online and the instance is down in fact (the derived read, pid-reuse-safe via the birth stamp). The `launch_predates_boot` conjunct is REMOVED from the persistent path. The heal (leg a) stays as is.\n2. The releases#78 leg (c) freeze (force-kill during operation is not auto-relaunched, to free an exe for overwrite) no longer governs persistent instances. An operator who needs a persistent shell to stay down uses the surfaces that say so (`teardown`, or a non-persistent manifest), not a kill. The mid-deploy exe-overwrite concern that motivated the freeze is answered by the update path, not by leaving a declared-persistent surface down.\n3. CONTEXT.md's sentence (\"a persistent shell is automatically brought online whenever its owner endpoint is online\") is already the contract; KNOWN-HAZARDS 2.7 and MANIFEST.md's sleep/wake text get amended to drop the boot-instant conjunct for persistent instances, and the REQ-SHELL-PERSISTENT-BOOT-RESTORE / REQ-SHELL-PERSISTENT-OWNER-ONLINE-RESTORE titles are re-worded in the same change. Regression cell: the daemon-restart shape (corpse launched AFTER machine boot, owner online, persistent) is restored on the owner-online edge — the exact row the current discriminant refuses.\n4.

Skip phases only when explicitly justified.\n\nWhen exploring the codebase, read `CONTEXT.md` (if it exists) to get a clear mental model of the relevant modules, and check ADRs in the area you're touching.\n\n## Phase 1 — Build a feedback loop\n\n**This is the skill.** Everything else is mechanical. If you have a **tight** pass/fail signal for the bug — one that goes red on _this_ bug — you will find the cause; bisection, hypothesis-testing, and instrumentation all just consume it. If you don't have one, no amount of staring at code will save you.\n\nSpend disproportionate effort here. **Be aggressive. Be creative. Refuse to give up.**\n\n### Ways to construct one — try them in roughly this order\n\n1. **Failing test** at whatever seam reaches the bug — unit, integration, e2e.\n2. **Curl / HTTP script** against a running dev server.\n3. **CLI invocation** with a fixture input, diffing stdout against a known-good snapshot.\n4. **Headless browser script** (Playwright / Puppeteer) — drives the UI, asserts on DOM/console/network.\n5. **Replay a captured trace.** Save a real network request / payload / event log to disk; replay it through the code path in isolation.\n6. **Throwaway harness.** Spin up a minimal subset of the system (one service, mocked deps) that exercises the bug code path with a single function call.\n7. **Property / fuzz loop.** If the bug is \"sometimes wrong output\", run 1000 random inputs and look for the failure mode.\n8. **Bisection harness.** If the bug appeared between two known states (commit, dataset, version), automate \"boot at state X, check, repeat\" so you can `git bisect run` it.\n9. **Differential loop.** Run the same input through old-version vs new-version (or two configs) and diff outputs.\n10. **HITL bash script.** Last resort. If a human must click, drive _them_ with `scripts/hitl-loop.template.sh` so the loop is still structured. Captured output feeds back to you.\n\nBuild the right feedback loop, and the bug is 90% fixed.\n\n### Tighten the loop\n\nTreat the loop as a product. Once you have _a_ loop, **tighten** it:\n\n- Can I make it faster? (Cache setup, skip unrelated init, narrow the test scope.)\n- Can I make the signal sharper? (Assert on the specific symptom, not \"didn't crash\".)\n- Can I make it more deterministic? (Pin time, seed RNG, isolate filesystem, freeze network.)\n\nA 30-second flaky loop is barely better than no loop; a 2-second deterministic one is tight — a debugging superpower.\n\n### Non-deterministic bugs\n\nThe goal is not a clean repro but a **higher reproduction rate**. Loop the trigger 100×, parallelise, add stress, narrow timing windows, inject sleeps. A 50%-flake bug is debuggable; 1% is not — keep raising the rate until it's debuggable.\n\n### When you genuinely cannot build a loop\n\nStop and say so explicitly. List what you tried. Ask the user for: (a) access to whatever environment reproduces it, (b) a captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.\n\n### Completion criterion — a tight loop that goes red\n\nPhase 1 is done when the loop is **tight** and **red-capable**: you can name **one command** — a script path, a test invocation, a curl — that you have **already run at least once** (paste the invocation and its output), and that is:\n\n- [ ] **Red-capable** — it drives the actual bug code path and asserts the **user's exact symptom**, so it can go red on this bug and green once fixed. Not \"runs without erroring\" — it must be able to _catch this specific bug_.\n- [ ] **Deterministic** — same verdict every run (flaky bugs: a pinned, high reproduction rate, per above).\n- [ ] **Fast** — seconds, not minutes.\n- [ ] **Agent-runnable** — you can run it unattended; a human in the loop only via `scripts/hitl-loop.template.sh`.\n\nIf you catch yourself reading code to build a theory before this command exists, **stop — jumping straight to a hypothesis is the exact failure this skill prevents.** No red-capable command, no Phase 2.\n\n## Phase 2 — Reproduce + minimise\n\nRun the loop. Watch it go red — the bug appears.\n\nConfirm:\n\n- [ ] The loop produces the failure mode the **user** described — not a different failure that happens to be nearby. Wrong bug = wrong fix.\n- [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).\n- [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.\n\n### Minimise\n\nOnce it's red, shrink the repro to the **smallest scenario that still goes red**. Cut inputs, callers, config, data, and steps **one at a time**, re-running the loop after each cut — keep only what's load-bearing for the failure.\n\nWhy bother: a minimal repro shrinks the hypothesis space in Phase 3 (fewer moving parts left to suspect) and becomes the clean regression test in Phase 5.\n\nDone when **every remaining element is load-bearing** — removing any one of them makes the loop go green.\n\nDo not proceed until you have reproduced **and** minimised.\n\n## Phase 3 — Hypothesise\n\nGenerate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.\n\nEach hypothesis must be **falsifiable**: state the prediction it makes.\n\n> Format: \"If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse.\"\n\nIf you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.\n\n**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly (\"we just deployed a change to #3\"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it — proceed with your ranking if the user is AFK.\n\n## Phase 4 — Instrument\n\nEach probe must map to a specific prediction from Phase 3. **Change one variable at a time.**\n\nTool preference:\n\n1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.\n2. **Targeted logs** at the boundaries that distinguish hypotheses.\n3. Never \"log everything and grep\".\n\n**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.\n\n**Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.\n\n## Phase 5 — Fix + regression test\n\nWrite the regression test **before the fix** — but only if there is a **correct seam** for it.\n\nA correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site. If the only available seam is too shallow (single-caller test when the bug needs multiple callers, unit test that can't replicate the chain that triggered the bug), a regression test there gives false confidence.\n\n**If no correct seam exists, that itself is the finding.** Note it. The codebase architecture is preventing the bug from being locked down. Flag this for the next phase.\n\nIf a correct seam exists:\n\n1. Turn the minimised repro into a failing test at that seam.\n2. Watch it fail.\n3. Apply the fix.\n4. Watch it pass.\n5. Re-run the Phase 1 feedback loop against the original (un-minimised) scenario.\n\n## Phase 6 — Cleanup + post-mortem\n\nRequired before declaring done:\n\n- [ ] Original repro no longer reproduces (re-run the Phase 1 loop)\n- [ ] Regression test passes (or absence of seam is documented)\n- [ ] All `[DEBUG-...]` instrumentation removed (`grep` the prefix)\n- [ ] Throwaway prototypes deleted (or moved to a clearly-marked debug location)\n- [ ] The hypothesis that turned out correct is stated in the commit / PR message — so the next debugger learns\n\n**Then ask: what would have prevented this bug?** If the answer involves architectural change (no good test seam, tangled callers, hidden coupling) hand off to the `/improve-codebase-architecture` skill with the specifics.

Synthesized from a grilling session.\n 4:> Canonical detail lives in [`CONTEXT.md`](./CONTEXT.md) (glossary/model) and [`docs/adr/`](./docs/adr/) (decisions). This PRD states *what* and *why*; those state *meaning* and *rationale*. Where they conflict, the ADRs win.\n...\n 7:\n*8:## 1. Vision\n 9:\n 10:spt-core is a **harness-independent core for an agent ecosystem**: inter-agent messaging, live-agent lifecycle, terminal hosting, seamless self-update, and zero-config cross-machine networking — shipped as both a Rust library workspace and a single canonical binary (`spt` / `spt.exe`).\n 11:\n*12:It is the ground-up rebuild of `claude_skill_owl` (\"modern SPT\"), untethering the system from Claude Code so that **any** agent runtime — Claude Code, Codex, Cursor, headless, or novel surfaces — can participate by either shelling out to the binary or linking the crates. The first thing built atop it is a rebuilt `spt` plugin reaching parity with today's system; the networking, terminal-wrapper, and multi-instance capabilities then make an agent reachable and operable across all of a user's machines.\n 13:\n*14:## 2. 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*34:- **Concrete Shells / PresenceChannel implementation / presence gossip** — only the seams ship (§Endpoints).\n 35:- **Remote command execution on another user's node** and **instantiate-anywhere** — seam-compatible, deferred behind a consent/security gate.\n 36:- **Sidecar adapter protocol**, **manifest includes**, **scrollback disk-spillover**, **predictive/state-sync terminal layer** — see [`docs/DEFERRED.md`](./docs/DEFERRED.md).\n 37:- **A model/billing opinion** — SPT is not a harness; model choice is always the adapter's.\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 73:- **R-SEAM-psyche** `spawn-psyche`: two templates (fresh / resume-with-`$session_id`), both carrying spt-core-owned `$psyche_prompt`; adapter owns model + harness-specific preamble.\n*74:- **R-SEAM-history** Two history paths: **A** adapter-owned locate-template + adapter-owned **normalize-command**; **B** spt-core-native `history-log` store (also used for Shells). Adapter-owned normalize is mandated over built-in parsers (Codex-vs-Claude evidence — transcript formats diverge and move fast).\n 75:- **R-SEAM-activity** Activity/idle is reported by the adapter via `api` commands into **perch sentinels** — never PTY-quiescence, never a manifest-declared idle signal.\n 76:- **R-SEAM-inject** `inject-input`: configurable per activity-state (activity/idle/both), any combination of PTY injection, `api poll`, in-session relay, or HTTP POST to a local port.\n 77:- **R-SEAM-resume** Two resume forms: **fresh-with-preload** (cleared context + `$psyche-context` preload) and **continue-existing** (native harness resume).\n*78:- **R-SEAM-capability** Static manifest list of hostable endpoint types (consumed by the registry; a node may host only Shells).\n 79:- **R-SEAM-update** `adapter-update`: file-pull (regex + gh repo) or delegated-command. spt-core conducts adapter updates after bootstrap.\n 80:\n*81:### 8.2 Inbound — the `api` subcommand surface\n 82:- **R-API-1** All machinery-facing commands are `api`-prefixed; every invocation carries `adapter_name`. The agent-facing verbs (`send`, `ring`, `ready`, …) stay unprefixed.\n 83:- **R-API-2** Surface: `api bind`, `api listen` (long-running relay), `api poll [--include-deferred]`, `api state <busy|idle>` (+ `api echo-gate <set|clear>`, `--no-gate`), `api worker-start|worker-stop|worker-poll`, `api boundary <clear|compact>` (carries new `session_id`), `api session-end [--erase]`, `api history-log`, `api presence`, `api seed --pid <pid>`.\n 84:- **R-API-3** `commune`/`signoff` are **file-drops**, not commands; the daemon watches the manifest-declared dirs and is the single writer.\n 85:\n*86:### 8.3 Startup flows\n 87:- **R-START-1** Adapters never resolve `$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. Endpoints, Shells & the Instance model\n 95:\n*96:### 9.1 Endpoint types\n## ROADMAP.md#158C\n*1:# spt-core Roadmap\n 2:\n 3:> Lightweight-but-structured path from design → fruition. Not a GSD/phase-gated process — a clear sequence with de-risk gates. Planning corpus is complete (PRD + CONTEXT + 5 ADRs + 6 design docs); this is how we build it.\n 4:\n*5:## End goal\n 6:\n 7:A harness-independent core for an agent ecosystem — messaging, live-agent lifecycle, terminal hosting, **first-class P2P networking**, and a runtime-manifest harness contract — shipped as Rust crates + a single `spt` binary. The proof: the same agent runs natively across all of a user's machines with a synced mind, reachable and operable from anywhere, with seamless self-update and zero-config cross-machine messaging. First thing built atop it: a rebuilt `spt` plugin at parity with today's modern SPT.\n 8:\n*9:## Scope decisions (locked)\n 10:\n 11:- **v1 = the full PRD, networking included.** The networked element is the *reason* spt-core exists; it is not deferrable to v1.1.\n 12:- **The hard freeze on `claude_skill_owl` is not a clock.** It works today and delivers value as-is while spt-core is built — no schedule pressure from it.\n...\n 14:\n*15:## Path to fruition (sequence)\n 16:\n 17:**Stage A — Red-team review (before building).** Pressure-test the design adversarially. Focus on the riskiest architectural decisions, not bikeshedding. Tools: `plan-eng-review` (architecture) + `codex` (adversarial second opinion). Scope-cutting is *not* a goal (v1 is locked as full PRD), but surfacing contradictions / over-engineering / unproven assumptions is.\n 18:\n...\n 24:\n*25:## Milestones (all v1)\n 26:\n 27:- **M0 — Workspace + commodity layer.** Cargo workspace; `spt-proto` (wire envelope grammar, endpoint types, framing, Ed25519 identity, typed+binary payloads) + `spt-store` (spool, perch layout, trust store, registry persistence). Copy-verbatim the stable formats from the sister project (ADR-0001).\n 28:- **M1 — Local messaging + binary.** `spt-msg` (delivery TCP+spool, routing, send/ring/ready) + the `spt` binary + CLI. **= the killer quickstart (local): two agents exchange a message.** Task breakdown: [`M1-PLAN.md`](./M1-PLAN.md).\n...\n 38:- **M4 — Networking + instances. ✅ delivered (2026-06-04).** The eighth crate `spt-net` (Iroh WAN endpoint bound to the node's own Ed25519 identity, mDNS LAN discovery, TOTP-SPAKE2 pairing over a dedicated pre-trust ALPN with transcript binding / rate limiting / seed rotation+transfer, subnet registry + NDJSON replication under the per-node epoch lease) · the multi-instance model (registry rows + bare-id resolution refuse-and-qualify + visibility/sync-membership gates + rename/collision + **resting-...\n*39:- **M5 — Shells, presence, deferred capabilities. ✅ delivered (2026-06-04;** scope locked with user 2026-06-04, see [`M5-PLAN.md`](./M5-PLAN.md) + per-task JIT plans D0–D9).

The `spt-core/` default is deliberately distinct from the modern spt runtime's `spt/` home so a dev build never collides with a running spt-plugin during parity build-out (may stay `spt-core/` for good). 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 29:    <endpoint_id>/\n*30:      info.json                  identity, type, status, CURRENT adapter_name (+ capability set if Shell)\n 31:      spool.db                   SQLite spool (typed + binary payloads)\n 32:      status                     active | dormant | suspended    (agent endpoints)\n 33:      nested/<child_id>/         Worker / Psyche perches (own info.json, spool)\n*34:      shells/<adapter>-<n>/      Shell perches owned by this endpoint (GameRobot-0, GameRobot-1…)\n*35:        info.json                type=Shell, owner, adapter_name, status (online|offline), alias?\n 36:        spool.db                 command + durable text/file (sensory is REST-only, unspooled)\n 37:  history/                       node-local logs (mirrors perch structure)\n 38:    <endpoint_id>/\n 39:      sessions/<session_id>.jsonl    agent Path-B native logs\n*40:      shells/<adapter>-<n>.jsonl     shell-link command/text/sensory exchange log\n 41:  registry/                      ── ephemeral ── local cache of the subnet registry\n 42:  index/                         ── derived, regenerable ── materialized indexes (ADR-0037)\n 43:    project-index.json           endpoint→project attribution (schema-versioned; daemon-written)\n...\n 47:    <adapter>/web/               core-owned adapter served root; output bytes survive deactivation\n*48:  serve/registry                 authoritative serving entries + persistent name ownership\n 49:```\n 50:\n*51:### The contact ledger — `identity/trust/contacts.json` (DOORBELL W3)\n 52:\n 53:<!-- [doc->REQ-UNLISTED-CONTACT-LEDGER] -->\n 54:\n...\n 88:\n*89:### Registry snapshots + the resource-advertisement blurb (D9)\n 90:\n 91:<!-- [doc->REQ-INST-14] -->\n 92:\n...\n 109:\n*110:## serve/registry — authoritative serving assignments\n 111:\n 112:<!-- [doc->REQ-WEB-SERVING-REGISTRY] -->\n 113:\n...\n 153:\n*154:## tracked/ — the context git repo\n 155:\n 156:- A local **git repository** (carried forward from modern SPT's mechanism).

Resolves PRD §17.3 (Psyche live/project authoring directives) and the memformat redesign. Governs how the Psyche authors, structures, syncs, and surfaces an agent's context. On-disk layout: `docs/STORAGE.md`. 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.

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).

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**.

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). A **designed-in commitment**, not an afterthought — grounded in research on critically-acclaimed developer docs (Stripe, Twilio, the Rust Book, FastAPI, Cloudflare, Anthropic, Diátaxis, `llms.txt`, Google dev style guide). Governs the **shipped product docs** (authored as code lands); the planning docs (CONTEXT/PRD/ADRs/design docs) are internal and separate.\n 4:\n*5:## The defining constraint: a dual audience\n 6:\n 7:spt-core's docs serve **two readers at once** — human developers *and* the **AI dev-agents that build integrations with it**.

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.

Vision\n  9│\n 10│spt-core is a **harness-independent core for an agent ecosystem**: inter-agent messaging, live-agent lifecycle, terminal hosting, seamless self-update, and zero-config cross-machine networking — shipped as both a Rust library workspace and a single canonical binary (`spt` / `spt.exe`).\n 11│\n*12│It is the ground-up rebuild of `claude_skill_owl` (\"modern SPT\"), untethering the system from Claude Code so that **any** agent runtime — Claude Code, Codex, Cursor, headless, or novel surfaces — can participate by either shelling out to the binary or linking the crates. The first thing built atop it is a rebuilt `spt` plugin reaching parity with today's system; the networking, terminal-wrapper, and multi-instance capabilities then make an agent reachable and operable across all of a user's machines.\n 13│\n*14│## 2. 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*34│- **Concrete Shells / PresenceChannel implementation / presence gossip** — only the seams ship (§Endpoints).\n 35│- **Remote command execution on another user's node** and **instantiate-anywhere** — seam-compatible, deferred behind a consent/security gate.\n 36│- **Sidecar adapter protocol**, **manifest includes**, **scrollback disk-spillover**, **predictive/state-sync terminal layer** — see [`docs/DEFERRED.md`](./docs/DEFERRED.md).\n 37│- **A model/billing opinion** — SPT is not a harness; model choice is always the adapter's.\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 73│- **R-SEAM-psyche** `spawn-psyche`: two templates (fresh / resume-with-`$session_id`), both carrying spt-core-owned `$psyche_prompt`; adapter owns model + harness-specific preamble.\n*74│- **R-SEAM-history** Two history paths: **A** adapter-owned locate-template + adapter-owned **normalize-command**; **B** spt-core-native `history-log` store (also used for Shells). Adapter-owned normalize is mandated over built-in parsers (Codex-vs-Claude evidence — transcript formats diverge and move fast).\n 75│- **R-SEAM-activity** Activity/idle is reported by the adapter via `api` commands into **perch sentinels** — never PTY-quiescence, never a manifest-declared idle signal.\n 76│- **R-SEAM-inject** `inject-input`: configurable per activity-state (activity/idle/both), any combination of PTY injection, `api poll`, in-session relay, or HTTP POST to a local port.\n 77│- **R-SEAM-resume** Two resume forms: **fresh-with-preload** (cleared context + `$psyche-context` preload) and **continue-existing** (native harness resume).\n*78│- **R-SEAM-capability** Static manifest list of hostable endpoint types (consumed by the registry; a node may host only Shells).\n 79│- **R-SEAM-update** `adapter-update`: file-pull (regex + gh repo) or delegated-command. spt-core conducts adapter updates after bootstrap.\n 80│\n*81│### 8.2 Inbound — the `api` subcommand surface\n 82│- **R-API-1** All machinery-facing commands are `api`-prefixed; every invocation carries `adapter_name`. The agent-facing verbs (`send`, `ring`, `ready`, …) stay unprefixed.\n 83│- **R-API-2** Surface: `api bind`, `api listen` (long-running relay), `api poll [--include-deferred]`, `api state <busy|idle>` (+ `api echo-gate <set|clear>`, `--no-gate`), `api worker-start|worker-stop|worker-poll`, `api boundary <clear|compact>` (carries new `session_id`), `api session-end [--erase]`, `api history-log`, `api presence`, `api seed --pid <pid>`.\n 84│- **R-API-3** `commune`/`signoff` are **file-drops**, not commands; the daemon watches the manifest-declared dirs and is the single writer.\n 85│\n*86│### 8.3 Startup flows\n 87│- **R-START-1** Adapters never resolve `$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.

Planning corpus is complete (PRD + CONTEXT + 5 ADRs + 6 design docs); this is how we build it.\n  4│\n *5│## End goal\n  6│\n  7│A harness-independent core for an agent ecosystem — messaging, live-agent lifecycle, terminal hosting, **first-class P2P networking**, and a runtime-manifest harness contract — shipped as Rust crates + a single `spt` binary. The proof: the same agent runs natively across all of a user's machines with a synced mind, reachable and operable from anywhere, with seamless self-update and zero-config cross-machine messaging. First thing built atop it: a rebuilt `spt` plugin at parity with today's modern SPT.\n  8│\n *9│## Scope decisions (locked)\n 10│\n 11│- **v1 = the full PRD, networking included.** The networked element is the *reason* spt-core exists; it is not deferrable to v1.1.\n 12│- **The hard freeze on `claude_skill_owl` is not a clock.** It works today and delivers value as-is while spt-core is built — no schedule pressure from it.\n   │...\n 14│\n*15│## Path to fruition (sequence)\n 16│\n 17│**Stage A — Red-team review (before building).** Pressure-test the design adversarially.

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`.

Resolves PRD §17.3 (Psyche live/project authoring directives) and the memformat redesign. Governs how the Psyche authors, structures, syncs, and surfaces an agent's context. On-disk layout: `docs/STORAGE.md`. 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.

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.

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).

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.

This project follows\r\n[Keep a Changelog](https://keepachangelog.com) and semantic versioning.\r\nPre-1.0, choose the bump by what a user can notice: **minor** when a release\r\nbreaks something, or changes the observable behavior of existing surfaces\r\nbroadly; **patch** for fixes, and for additive opt-in capability — a new key,\r\nflag, or page that no existing user can encounter without opting into it.\r\n\r\n## [0.68.0] - 2026-09-08\r\n\r\nWeb serving. Files, directories, adapter documentation and the changelog are\r\nreachable at node-prefixed addresses on the local server, and an address that\r\nnames another machine in the subnet is answered by the machine that owns it.\r\nMessages can carry attachments the receiver pulls on demand, every message\r\ngets a short ID to show or reply to, and a machine with no spt on it can be\r\nhanded the binary over the local network. The `XFER` access surface is retired.\r\n\r\n### Added\r\n\r\n<!-- [doc->REQ-WEB-SERVING-REGISTRY] -->\r\n- `spt serve add`, `spt serve rm`, and `spt serve list --json` manage live file\r\n  and directory references. Same-name registrations receive stable numbered\r\n  suffixes; removing an entry never deletes its source. Only the same absolute\r\n  path and kind may reclaim a retired name.\r\n- Every registered adapter gets a core-owned `web/` output directory.\r\n  `[adapter].web_short_path` optionally gives it a short URL alias. Removing\r\n  an adapter stops serving its output without deleting the files.\r\n- `spt adapter add` names each manifest key it does not know on stderr\r\n  (`manifest: unknown key [<table>].<key> (ignored)`) and still registers;\r\n  a misspelled optional key is no longer visible only by its absence.\r\n<!-- [doc->REQ-WEB-ACCESS-SURFACE] -->\r\n- `WEB` joins the access-control vocabulary. It is open by default within the\r\n  subnet, but explicit WEB denies still govern. Existing file transfer is\r\n  unchanged.\r\n<!-- [doc->REQ-WEB-CROSS-NODE-PROXY] -->\r\n- A served resource's URL now works from every machine in the subnet: a\r\n  request for `/<peer>/…` on the local loopback server is answered by the\r\n  owning node through the local daemon. The body streams and nothing is\r\n  cached; `HEAD` and `Range` requests are honored by the owner. An owner\r\n  that refuses answers 403 naming `WEB`; an owner that cannot be reached\r\n  answers 502 naming the node, within a bounded time.\r\n- `spt send --attachment <path>` sends a file with a message. The file's bytes\r\n  are captured as they are at send time, so later edits or a deletion do not\r\n  change what arrives, and the receiver pulls them with `spt fetch` when it\r\n  wants them. `--ttl` sets how long an attachment stays available (default 30\r\n  days, a unit is required); expired attachments answer 404 immediately.\r\n- Every message now carries a short ID. `spt msg show <id>` prints a message by\r\n  it, and `spt send --reply-to <id>` marks what a message answers. Messages\r\n  from another machine resolve through the machine that holds them.\r\n- `spt serve lan --bootstrap` hands the spt binary to a machine that is not yet\r\n  a node, over the local network on port 5470. It is off by default and off\r\n  again after every daemon restart, serves only the binary, its release sidecar\r\n  and an install command, and refuses to start by name when the applied update\r\n  set is not signed or does not match. It prints a checksum per platform, and\r\n  `spt install` gains `--expect-sha256` and `--release-json` so what was\r\n  downloaded can be compared before it is run. The documentation port is\r\n  untouched and stays on loopback.\r\n- `[adapter].docs_dir` publishes an adapter's own documentation at the `docs`\r\n  segment of its address, beside the adapter's output directory rather than in\r\n  place of it. A missing key, an unreadable manifest, a path that escapes the\r\n  adapter's directory, and a directory that has since been removed all answer\r\n  the same 404 naming what was asked for.\r\n- The changelog is now one of the pages the local documentation server offers.\r\n- A harness is told when a message it receives refers to a file the reader\r\n  cannot open — an attachment to pull, or a path that belongs to another\r\n  machine — instead of leaving the reader to discover it. For a path on\r\n  another machine, that machine can be asked to publish it and answers with a\r\n  link; it honors such a request only for its own endpoints, so no third\r\n  machine can have someone else's file exposed.\r\n\r\n### Changed\r\n\r\n<!-- [doc->REQ-WEB-URL-NODE-PREFIX] -->\r\n- The loopback HTTP server now has a node-prefixed resource index with HTML\r\n  and `?json` views. `/` redirects to `/<node>/`; canonical docs URLs live at\r\n  `/<node>/docs/`, while existing bare docs paths remain compatibility aliases.\r\n\r\n### Removed\r\n\r\n- The `XFER` access surface is retired: attachments replaced the transfer it\r\n  gated, so the entry leaves the access-control vocabulary along with the\r\n  transfer itself. An existing rule that names `XFER` is kept and reported at\r\n  load rather than dropped silently; it no longer governs anything. The shell\r\n  channel's own transfer progress is unaffected.\r\n\r\n### Fixed\r\n\r\n<!-- [doc->REQ-IO-MSG-EDGES] -->\r\n- Messages delivered by `spt api listen` now reach the receiver's incoming-message\r\n  history and last-message state, for both queued backlog and live TCP delivery.\r\n  A later hook poll does not record those deliveries again; filtered notifications\r\n  are not recorded as delivered messages.\r\n- A node's message and activity history reads back correctly once its log grows\r\n  past a quarter of a megabyte. Positions no longer restart from the beginning,\r\n  so a request for everything since a given point no longer comes back empty or\r\n  repeats entries that were already seen, and an oversized position is answered\r\n  with the current head instead of skipping a page.\r\n- An agent's own saved context is no longer overwritten, unread, by the\r\n  automatic summary that follows it. The automatic summary is filed directly\r\n  and never writes to the file an agent saves its own context to.\n…\n\n…\nFirst public release of `spt`.","startLine":1,"lineNumbers":[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104,null,107,null,3115]},"fileSize":219822,"meta":{"source":{"type":"path","value":"C:\\Users\\decid\\Documents\\projects\\spt-core\\.worktrees\\287-shellrestore\\CHANGELOG.md"},"truncation":{"direction":"head","truncatedBy":"lines","totalLines":3115,"totalBytes":6219,"outputLines":103,"outputBytes":6219,"shownRange":{"start":1,"end":103},"nextOffset":104}}},"isError":false,"timestamp":1788999516489}}

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 `is_process_alive(pid)` reads \"alive\" for a torn-down endpoint as long as the daemon runs — while `clean_stale_entries` (dead-pid deletion) can no longer distinguish a dead endpoint from a live one.

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 recovers the instance) refuses `SHELL_ALREADY_ONLINE`, gated on the very state that is wrong; and `shell cmd`'s wake-if-offline arm reads \"not offline\", skips the wake, and spools the command to a corpse — accepted happily, drained by nobody, **indistinguishable from a busy s…\n78:- **Invariant:** ONLINE-ness is **derived**, never the recorded field alone: `status == online` **AND** the recorded `shell.pid` is not *provably* dead.

A machine death breaks no link, so `close_shell` never runs and 2.6's stale record survives the reboot; when the owner comes back online, the wake cascade reads the **recorded** field, sees `online`, and skips the relaunch of a binary that has not existed since the previous boot. Nothing else corrects it: the instance is down forever, with no error anywhere, until a human happens to run `relink`. Every `persistent` instance on the node is stranded by one restart, together.\n86:- **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 a clean-looking context render must never be taken as proof the class did not occur. The correct falsifier is the **on-disk record**.\n87:- **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. The test is not weak; it gives a true answer to the wrong question, so a reader asking \"is the cascade covered?\" is told yes.

Every consumer of the recorded field then inherits the lie — `shell list` reports online indefinitely; `relink` (the one command that recovers the instance) refuses `SHELL_ALREADY_ONLINE`, gated on the very state that is wrong; and `shell cmd`'s wake-if-offline arm reads \"not offline\", skips the wake, and spools the command to a corpse — accepted happily, drained by nobody, **indistinguishable from a busy s…\n- **Invariant:** ONLINE-ness is **derived**, never the recorded field alone: `status == online` **AND** the recorded `shell.pid` is not *provably* dead. Provably dead is narrow — pid parked, non-zero, `!is_process_alive`; pid absent, unparseable, or `0` (a broker-hosted spawn whose backend exposed no pid) reads **alive**, the same fail-toward-alive parity 2.5 holds, so a backend the resolver cannot see is never declared dead. **The recycled-pid caveat is narrowed since BAROMETER W2 and is now conditional on the stamp:** a launch parks a **birth stamp** beside the pid (`shell.launch.json`), and the probe runs the PAIR test — same pid, *different* start time ⇒ **gone**, so a pid the OS handed to an unrelated process no longer masks a dead instance. That case m…\n- **No spontaneous relaunch of a SAME-BOOT death (operator-ratified, flynn 2026-07-25; re-based BAROMETER W2):** the reconciler does NOT adopt an instance whose binary died during this boot. Every reason an operator stops a shell is a reason not to want it back a tick later: mid-deploy (a shared install dir makes \"kill the process\" routine on Windows, since a running exe cannot be overwritten) an auto-relaunch would run the **old** binary out of the file being replaced — worse than a failed install — and it turns quarantining a misbehaving shell into a restart loop. For those, recovery stays demand-driven: `relink`, or a `shell cmd` that wakes. `relink` probes **locally** rather than trusting a daemon sweep, so recovery holds with the daemon down.\r\n- **What holds that open is no longer the stale record (BAROMETER W2):** until W2 the guarantee rested on an accident: a force-killed instance was held out of the eligible set because its record still said `online`, and the eligibility read took that field raw. 2.7 heals that record to the truth, which removes the accidental protection — so the guard had to move to a rule that *states* it. Eligibility is now recorded-`offline` **AND** (no corpse, **or** the corpse's recorded launch **predates the boot instant**). A steady-state force-kill leaves a corpse launched *after* boot, which the predicate can never accept, so the ruling is preserved **by construction** rather than by a second rule. A restart casualty is the one case the predicate does accept, and it …\n- **spt-core mapping:** `spt_store::shellinfo::{shell_pid_provably_dead, effective_status, is_shell_online}` (the resolver — the shell-side twin of 2.5's `liveness.rs`, which gave *agent* perches exactly this and which shells never got); consumers in `linkhost::{relink_shell, prepare_drive, run_action}`, `shelldisc::discover`, `activity::observe_links`; the class-(c) eligibility read is `spt_daemon::shellwake::watcher_eligible` (+ `launch_predates_boot`, `BOOT_RESTORE_SLACK_MS`), and the birth stamp it rests on is `shellinfo::{ShellLaunch, record_shell_launch, read_shell_launch}`.\r\n- **Source:** spt-core, flynn's spt-alchemy field report (2026-07-25) — a deterministic recipe, not a race.

A machine death breaks no link, so `close_shell` never runs and 2.6's stale record survives the reboot; when the owner comes back online, the wake cascade reads the **recorded** field, sees `online`, and skips the relaunch of a binary that has not existed since the previous boot. Nothing else corrects it: the instance is down forever, with no error anywhere, until a human happens to run `relink`. Every `persistent` instance on the node is stranded by one restart, together.\r\n- **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 a clean-looking context render must never be taken as proof the class did not occur. The correct falsifier is the **on-disk record**.\r\n- **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. The test is not weak; it gives a true answer to the wrong question, so a reader asking \"is the cascade covered?\" is told yes. This is the third suppressed-arm instance found in one week, and the pattern is the same each time: **a fixture that establishes the precondition the code under test is supposed to establish.**\r\n- **Invariant:** a node restart must not strand a `persistent` instance. Two legs, and each is worthless alone. **(a) The record stops lying:** the daemon-side reconciler heals a recorded `online` that 2.6's derivation contradicts, writing `offline` — every cycle, **guarded on an actual change** (a heal that rewrote each tick would be a stream of identical writes and would destroy the record's mtime as a signal). **(b) The restart shape reaches a restoration path:** a once-per-daemon-generation boot sweep — and, for an owner that comes online after that sweep has run, an **owner offline→online edge** in the reconcile loop running the identical body (releases#228) — relaunches an instance when **all four** hold — the adapter section declares `persistent`; the…\n- **Regression shape (the row the suppressed fixture cannot express):** construct the restart shape **without a suspend edge** — an instance whose record says `online` over a corpse that predates boot, with an online owner — and assert it is restored. A fixture that suspends first re-creates the suppressed arm and proves nothing about this class.\r\n- **spt-core mapping:** `spt_daemon::shellwake::{heal_stale_online_records, restore_persistent_shells_at_boot, restore_persistent_shells_on_owner_online, OwnerOnlineEdge, launch_predates_boot, BOOT_RESTORE_SLACK_MS}`; `spt_store::proc::boot_instant_ms`; `spt_store::shellinfo::{ShellLaunch, record_shell_launch, read_shell_launch}` (the birth stamp, parked at the two production pid-write sites the launch-site census identified).\r\n- **Source:** spt-core, BAROMETER W2 (releases#78) — field specimen `liam/alchemy-0`, a genuinely stranded record: `online` over a dead pid, no launch stamp, days old.\r\n<!-- [doc->REQ-HAZARD-RESTART-STRANDS-PERSISTENT-SHELLS] -->\r\n\r\n---\r\n\r\n## 3.

CONTEXT.md\n35:carries the canonical terms (activity observation; digest turn sealing;\n36:cross-node instance resolution); this ADR carries the why and the rejected\n37:shapes.\n38:\n39:## Decisions\n40:\n41:### 1. Activity observation is a first-class surface with two avenues — and the digest is not one of them\n42:\n43:<!-- [doc->REQ-ACTIVITY-INFO-PULL] --> <!-- [doc->REQ-ACTIVITY-LIST-JSON] -->\n44:\n45:**Push (shells only):** an owned Shell observes its owner's busy/idle\n46:transitions as an **activity frame** on the **existing shell-link event\n47:stream**. Link-scoped: the owner is implied by the link token — no addressing,\n48:no new authorization surface, no new verb.\n49:\n50:**Pull (everyone else):** current activity state is readable via\n51:`spt api endpoint-info` (single endpoint, point-in-time) and as a per-endpoint\n52:`activity` (busy|idle) key on `endpoint list --json` (many-at-once roster\n53:survey).\n54:\n55:**Rejected — riding the digest structured-delta stream.** The digest is a\n56:*content* surface sourced from normalized session logs; activity truth is a\n57:*perch sentinel*. Wedging state-about-the-endpoint into a content stream\n58:dilutes the glossary term, and the delta stream is unbuilt — the activity need\n59:would have dragged a whole subscriber machinery in by the ear. perri's original\n60:\"idle/busy in `endpoint digest --json`\" rider dissolved into the pull avenues.\n61:\n62:**Rejected — a new subscription verb.** A whole new surface for one consumer\n63:class, when the shell link already carries owner↔shell traffic in both\n64:directions and its lifecycle gives the restart story for free.\n65:\n66:### 2. Activity frames are drive-class: ephemeral, latest-wins, current-state-carrying\n67:\n68:The shell channel taxonomy already distinguishes **command** (discrete,\n69:durable) from **drive** (continuous, ephemeral, latest-wins). An activity frame\n70:is drive-class: it carries the *current* state, a redundant same-state resend\n71:is a harmless no-op (the consumer derives edges), and a missed frame is\n72:superseded by the next. **Never spooled, never replayed** — replaying a stale\n73:transition after a relink would be actively wrong. Current state is emitted on\n74:**every link establishment and re-link**, so a restarted consumer (or daemon)\n75:resynchronizes with zero extra machinery.\n76:\n77:### 3. The latency promise is bounded observation, anchored by a transition timestamp\n78:\n79:The contract promises **a frame per transition, promptly — sub-second class,\n80:never hard-real-time**. Each frame carries the **transition timestamp**: when\n81:the state *took effect* (the sentinel flip), not when the frame was emitted.\n82:Edge-anchored consumers (rebound's idle-countdown) anchor to that timestamp,\n83:so emission latency self-corrects out of their arithmetic.\n84:\n85:**Rejected — promising synchronous-with-report delivery.** That would weld the\n86:contract to the report command's plumbing. Bounded observation leaves the\n87:implementation free to start with daemon-side observation and later upgrade to\n88:report-path triggering with **no contract change**; the timestamp makes the\n89:difference invisible to consumers either way.\n90:\n91:### 4. The idle transition seals the digest turn\n92:\n93:<!-- [doc->REQ-DIGEST-SEAL-ON-IDLE] -->\n94:\n95:A turn's records gain their stable `seq` when the turn **finishes**, and the\n96:authoritative finish signal is the **idle transition** — the same\n97:adapter-reported signal decisions 1–3 instrument. Next-input arrival, the old\n98:seal trigger, is demoted to a harmless no-op fallback. Sealing is\n99:**idempotent and seq-stable**: it assigns `seq` to what the log holds at idle,\n100:and a late-flushing straggler record folds into the sealed turn without\n101:changing the assigned `seq`. The mint-then-idle deadlock dies at the source.\n102:\n103:**Which seq that names** (clarified 2026-07-24, A2 ruling — wording, not a\n104:decision change): \"the assigned `seq`\" that never changes is the turn's\n105:`input_seq`, the cursor anchor. Entry-level seqs inside the turn follow\n106:last-idx-wins and MAY advance FORWARD as a straggler folds into a trailing\n107:sprint — which is how that straggler reaches an `--after` consumer at all.\n108:Forward-only is the invariant; a backward or arbitrary move is a defect.\n109:\n110:**Rejected — extractor-observed log completion.** \"The log looks done\" is a\n111:heuristic — the same inference class the activity model explicitly bans\n112:(PTY-quiescence redux, one layer up).\n113:\n114:**Rejected — provisional seqs on partial turns.** Seq stability is the entire\n115:point of seq; a seq that can change is a scanner bug factory.\n116:\n117:### 5. Cross-node digest reach is pull-first\n118:\n119:<!-- [doc->REQ-DIGEST-CROSS-NODE-PULL] -->\n120:\n121:The `CROSS_NODE_M4` refusal on qualified addresses lifts for the **snapshot\n122:pull** (`endpoint digest <id@node>`, including `--after <seq>` incremental\n123:polling) under the **existing address gate** — the access model was ratified\n124:long ago; this is routing, not policy.

The\r\n  workaround (\"drive one more command after any tag\") is a discipline no\r\n  consumer should have to know.\r\n\r\nThe model already holds the answer to \"when is a turn finished\": the\r\nactivity/idle detection entry rules that idleness is **adapter-reported, never\r\ninferred** (not PTY-quiescence, not heuristics). This ADR makes that one\r\nsignal authoritative for two new consumers — and deliberately keeps the digest\r\nout of the activity business.\r\n\r\nThe operator ruled all decisions below on 2026-07-24 (rebound grill). CONTEXT.md\r\ncarries the canonical terms (activity observation; digest turn sealing;\r\ncross-node instance resolution); this ADR carries the why and the rejected\r\nshapes.\r\n\r\n## Decisions\r\n\r\n### 1. Activity observation is a first-class surface with two avenues — and the digest is not one of them\r\n\r\n<!-- [doc->REQ-ACTIVITY-INFO-PULL] --> <!-- [doc->REQ-ACTIVITY-LIST-JSON] -->\r\n\r\n**Push (shells only):** an owned Shell observes its owner's busy/idle\r\ntransitions as an **activity frame** on the **existing shell-link event\r\nstream**. Link-scoped: the owner is implied by the link token — no addressing,\r\nno new authorization surface, no new verb.\r\n\r\n**Pull (everyone else):** current activity state is readable via\r\n`spt api endpoint-info` (single endpoint, point-in-time) and as a per-endpoint\r\n`activity` (busy|idle) key on `endpoint list --json` (many-at-once roster\r\nsurvey).\r\n\r\n**Rejected — riding the digest structured-delta stream.** The digest is a\r\n*content* surface sourced from normalized session logs; activity truth is a\r\n*perch sentinel*. Wedging state-about-the-endpoint into a content stream\r\ndilutes the glossary term, and the delta stream is unbuilt — the activity need\r\nwould have dragged a whole subscriber machinery in by the ear. perri's original\r\n\"idle/busy in `endpoint digest --json`\" rider dissolved into the pull avenues.\r\n\r\n**Rejected — a new subscription verb.** A whole new surface for one consumer\r\nclass, when the shell link already carries owner↔shell traffic in both\r\ndirections and its lifecycle gives the restart story for free.\r\n\r\n### 2. Activity frames are drive-class: ephemeral, latest-wins, current-state-carrying\r\n\r\nThe shell channel taxonomy already distinguishes **command** (discrete,\r\ndurable) from **drive** (continuous, ephemeral, latest-wins). An activity frame\r\nis drive-class: it carries the *current* state, a redundant same-state resend\r\nis a harmless no-op (the consumer derives edges), and a missed frame is\r\nsuperseded by the next. **Never spooled, never replayed** — replaying a stale\r\ntransition after a relink would be actively wrong. Current state is emitted on\r\n**every link establishment and re-link**, so a restarted consumer (or daemon)\r\nresynchronizes with zero extra machinery.\r\n\r\n### 3. The latency promise is bounded observation, anchored by a transition timestamp\r\n\r\nThe contract promises **a frame per transition, promptly — sub-second class,\r\nnever hard-real-time**. Each frame carries the **transition timestamp**: when\r\nthe state *took effect* (the sentinel flip), not when the frame was emitted.\r\nEdge-anchored consumers (rebound's idle-countdown) anchor to that timestamp,\r\nso emission latency self-corrects out of their arithmetic.\r\n\r\n**Rejected — promising synchronous-with-report delivery.** That would weld the\r\ncontract to the report command's plumbing. Bounded observation leaves the\r\nimplementation free to start with daemon-side observation and later upgrade to\r\nreport-path triggering with **no contract change**; the timestamp makes the\r\ndifference invisible to consumers either way.\r\n\r\n### 4. The idle transition seals the digest turn\r\n\r\n<!-- [doc->REQ-DIGEST-SEAL-ON-IDLE] -->\r\n\r\nA turn's records gain their stable `seq` when the turn **finishes**, and the\r\nauthoritative finish signal is the **idle transition** — the same\r\nadapter-reported signal decisions 1–3 instrument. Next-input arrival, the old\r\nseal trigger, is demoted to a harmless no-op fallback. Sealing is\r\n**idempotent and seq-stable**: it assigns `seq` to what the log holds at idle,\r\nand a late-flushing straggler record folds into the sealed turn without\r\nchanging the assigned `seq`. The mint-then-idle deadlock dies at the source.\r\n\r\n**Which seq that names** (clarified 2026-07-24, A2 ruling — wording, not a\r\ndecision change): \"the assigned `seq`\" that never changes is the turn's\r\n`input_seq`, the cursor anchor. Entry-level seqs inside the turn follow\r\nlast-idx-wins and MAY advance FORWARD as a straggler folds into a trailing\r\nsprint — which is how that straggler reaches an `--after` consumer at all.\r\nForward-only is the invariant; a backward or arbitrary move is a defect.\r\n\r\n**Rejected — extractor-observed log completion.** \"The log looks done\" is a\r\nheuristic — the same inference class the activity model explicitly bans\r\n(PTY-quiescence redux, one layer up).\r\n\r\n**Rejected — provisional seqs on partial turns.** Seq stability is the entire\r\npoint of seq; a seq that can change is a scanner bug factory.\r\n\r\n### 5. Cross-node digest reach is pull-first\r\n\r\n<!-- [doc->REQ-DIGEST-CROSS-NODE-PULL] -->\r\n\r\nThe `CROSS_NODE_M4` refusal on qualified addresses lifts for the **snapshot\r\npull** (`endpoint digest <id@node>`, including `--after <seq>` incremental\r\npolling) under the **existing address gate** — the access model was ratified\r\nlong ago; this is routing, not policy. The **delta stream stays node-local**\r\nuntil a real cross-node subscriber exists (the same defer-until-consumer\r\ndiscipline applied to #70's spawn-on-named-node leg the same day). Note the\r\ncomposition: seal-on-idle's stable seqs are precisely what make cross-node\r\n`--after` polling trustworthy — a remote consumer polling a sealed turn can\r\nnever observe its seq shifting under them.\r\n\r\n## Consequences\r\n\r\n- The idle sentinel graduates from delivery-routing input to a **published\r\n  contract signal** with two external consumer classes (rebound's edge loop,\r\n  the digest sealer). Its write path is now load-bearing for latency: the\r\n  bounded-observation promise caps how lazily the daemon may notice a flip.\r\n- The shell frame vocabulary gains the activity frame; the published vocabulary\r\n  doc (REQ-SHELL-FRAME-VOCAB lineage) must carry its name, attrs (state +\r\n  transition timestamp), and drive-class semantics — adapter authors must\r\n  never be tempted to treat it as a durable event log.\r\n- `endpoint-info` and `endpoint list --json` gain additive keys — N-1 parsers\r\n  unaffected per the additive-evolution posture.\r\n- Scanners keyed on `seq` (alchemy-class) may drop their drive-one-more-command\r\n  discipline once seal-on-idle ships; liam re-verifies the\r\n  scanner-sees-latest-turn case at ship.\r\n- perri's locked contract (message SENT 2026-07-24) is binding: any deviation\r\n  from decisions 1–3 during build is a contract break and goes back through\r\n  the operator.\r","startLine":1,"lineNumbers":[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130,131,132,133,134,135,136,137,138,139,140,141,142,143,144,145,146,147,148]},"fileSize":8356,"meta":{"source":{"type":"path","value":"C:\\Users\\decid\\Documents\\projects\\spt-core\\.worktrees\\287-shellrestore\\docs\\adr\\0048-idle-edge-contract.md"}}},"isError":false,"timestamp":1788999531736}}

ROOT (releases#115): the three fault latches -- latch_turn, latch_ingest, latch_timeout -- live in memory behind a Mutex and are never seeded from disk, while the `psyche_host_error` stamp they compose to OUTLIVES the process on disk. After a bounce the stamp stands with nothing standing behind it, so the first `note_success` of ANY kind recomposes an empty latch set to None and clears a fault whose kind this process never learned. THE PER-KIND SEPARATION BAROMETER W1 BUILT IS THEREFORE UNDONE BY A RESTART: one working ingest erases a standing turn defect it says nothing about, which is precisely the vouching REQ-PSYCHE-HARD-BUDGET-PER-KIND exists to forbid -- the defect does not lose information at the margin, it re-opens a closed hazard. FIX: the stamp carries a SLOT-KEYED sibling map written by the SAME seam that writes the reason, so the sentence and the latches that produced it can never disagree on disk, and the pulse loop seeds its latches from that map at startup BEFORE any tick can report a success. THE KEY IS A LATCH SLOT, NOT A KIND, and the distinction is load-bearing rather than nominal: there are THREE slots against TWO kinds, because the timeout latch is shared cross-kind by the ruled BAROMETER W1 semantics and belongs to no kind at all -- a kind-keyed reading would be re-read later as a per-kind register and gain a fourth key the day a fourth kind appears. THE VOCABULARY IS CLOSED to those three slots, and an unrecognized key is IGNORED AND ANNOUNCED rather than seeded: an unknown slot can only come from a newer binary owning a latch this one has no code to clear, so seeding it would strand a fault that no success could ever recompose away, while dropping it silently would make a rollback that loses a standing fault look identical to a recovery. A PRE-#115 STAMP CARRIES NO SLOTS AND SEEDS NOTHING, deliberately: its kind is genuinely unrecoverable, and the honest behaviour for an unknown-kind fault is the one that shipped, where any success clears it (REQ-PSYCHE-STAMP-CLEAR-ANY-SUCCESS) -- inventing a kind for it would be worse than forgetting one. `reason` stays BYTE-IDENTICAL, and the map is serde-default plus skip-when-empty so a stamp with no standing latches serializes byte-identically to the pre-#115 shape; N-1 holds in BOTH directions, the old-binary/new-record leg proven by a MEASURED absence of any live deny_unknown_fields attribute repo-wide (zero, on this struct and on InfoJson alike) rather than by assuming serde's default. Gate: impl -- the slot-keyed map on the stamp, written by the single existing writer alongside the reason it composed to, the closed three-slot vocabulary with ignore-and-log on an unknown key, and the pulse-loop seed running before the first tick; unit -- a stamp whose slots record a standing INGEST fault SURVIVES a fresh process reporting a TURN success (the row the shipped code cannot pass, since an unseeded set recomposes to None and clears it), a seeded latch IS still cleared by a success of ITS OWN slot (asserted alongside, since the survival row alone passes an implementation that has simply stopped clearing anything), a pre-#115 SLOTLESS stamp is still cleared by any success (the N-1 behaviour-preservation row), and an UNKNOWN slot key seeds NO latch while a known key beside it in the same map DOES seed (the pair asserted together, since over an unknown key alone a seed-nothing implementation and a correct one agree).\"\nrequired_stages = [\"impl\", \"unit\"]  # ACTIVATED LOCKSMITH t1 (evidence lands here); MINTED LOCKSMITH t1 (todlando, 2026-08-03), releases#115.

CONTEXT.md states it plainly -- a persistent shell is automatically brought online whenever its owner endpoint is online -- and the shipped code honors that across a graceful suspend->wake rest edge ONLY. A machine restart produces no such edge and there is no boot-time restoration at all, so after a reboot every persistent shell on the node stays down until a human runs `relink` by hand, with no surface saying so. Field, HFENDULEAM 2026-08-01: the fleet came up at 01:11 and NOT ONE persistent shell came back; the two instances that did were relaunched by a human at 01:27, sixteen minutes later. TWO INDEPENDENT GATES, both of which must fall or the promise stays broken. GATE 1, no restoration path: the five launch sites all require either an explicit command, a rest edge, or a `wake_command` the adapter may deliberately not declare, and daemon boot starts only the servicehost sweep and the wake reconciler. GATE 2, the stale record blocks the cascade even when an edge DOES arrive: the to_active arm gates on the RECORDED status being offline, and a machine death breaks no link, so the close that would write offline never runs and the record says online over a corpse forever. LEG (a) HEALS THE RECORD TO THE TRUTH, with a BIRTH-STAMPED probe rather than bare pid liveness -- a pid namespace resets at boot, so a corpse pid can be REUSED by an unrelated process, and a reused pid reads alive, makes the derived status read online, and makes `relink` refuse SHELL_ALREADY_ONLINE: the one command that recovers the instance refusing on the very state that is wrong. TWO STAMPS ARE PARKED, NOT ONE, AND THE REASON IS A PLATFORM ASYMMETRY THAT WOULD OTHERWISE SHIP SILENTLY BROKEN ON LINUX: `process_started_at` returns a Windows FILETIME (absolute, comparable across boots) but on Linux returns field 22 of /proc/<pid>/stat, which is JIFFIES SINCE BOOT and resets every boot, so a value recorded before a restart is indistinguishable from a fresh one after it. The NATIVE stamp is therefore used for one question only -- the same-pid-different-process PAIR test within a single boot, mirroring `liveness::relay_liveness` -- and an ABSOLUTE epoch-ms launch stamp is parked beside it for the cross-boot question. LEG (b) IS A ONCE-PER-DAEMON-GENERATION BOOT SWEEP relaunching persistent instances whose owners are online, and its discriminant is THE LAUNCH STAMP PREDATES THE BOOT INSTANT, which preserves the class-c force-kill ruling BY CONSTRUCTION rather than by a second rule: a force-kill during steady-state operation leaves a corpse launched AFTER boot, so it is never spontaneously relaunched and the mid-deploy exe-overwrite hazard that ruling protects is untouched. A NAMED SLACK CONSTANT absorbs boot-instant jitter so a process launched moments after boot is never misclassified as a corpse. Gate: impl -- the two stamps parked at the two production pid-write sites (the census is authoritative: five LAUNCH sites funnel through exactly TWO pid writes), the birth-stamped death probe, the record heal in the daemon-side reconciler guarded on an actual change of the recorded value, the boot-instant helper on both platforms, and the boot sweep with its predates-boot discriminant plus slack; unit -- a reused pid (same pid, different birth stamp) reads GONE where bare-pid liveness reads alive (the row the shipped probe cannot pass), a same-pid-same-birth process reads HELD, the heal writes offline over a stale online record and writes NOTHING when the record already matches the truth (the guard asserted by counting writes, since a heal that rewrites every cycle passes any state-only assertion), a corpse launched BEFORE the boot instant is eligible for restore while one launched AFTER it is NOT (the class-c pair, asserted together since either alone passes an implementation that restores everything or nothing), and an instance whose OWNER is offline is not restored even though its corpse predates boot.\"\nrequired_stages = [\"doc\", \"impl\", \"unit\"]  # doc ACTIVATED BAROMETER W2 doc leg (doyle-ruled, this milestone): the CONTEXT.md `persistent` amendment states the boot sweep and its four conjunct gates incl. no-stamp => not restored, which IS this requirement's doc evidence; leaving the stage inactive would have made it evidence the registry cannot see.\n\n[[requirements]]\nid = \"REQ-SHELL-OWNER-ONLINE-RESTORE\"\ntitle = \"A `persistent` SHELL WHOSE OWNER ENDPOINT WAS NOT YET ONLINE WHEN THE BOOT SWEEP RAN IS RESTORED WHEN THAT OWNER COMES ONLINE, RATHER THAN STAYING DOWN UNTIL A HUMAN RELINKS IT. ROOT (releases#228): daemons boot before endpoints do, so the boot sweep of REQ-SHELL-PERSISTENT-BOOT-RESTORE correctly SKIPS an owner that is not up yet -- an offline owner is owed nothing -- and then nothing ever revisits it: the sweep is once per daemon generation, and bringup from offline produces no rest edge, so the ADR-0048 cascade never fires either. The shell stays down until a `shell cmd` wakes it or an operator relinks by hand, and whether a given node restart strands its shells is an ordering accident. THE ONCE-NESS IS SCHEDULING, NOT SAFETY (doyle, releases#228, re-measured at head): the `launch_predates_boot` corpse-boot discriminant is what preserves the force-kill ruling, and it is MONOTONE WITHIN A MACHINE BOOT -- every launch path restamps `launched_ms`, a kill never restamps, `boot_ms` is the machine boot instant -- so re-evaluating the conjuncts later in a generation can only refuse MORE, never less. FIX: the reconcile loop carries the SAME per-owner restore body the boot sweep runs, triggered on owner offline->online transitions since the last pass. THE TRIGGER IS AN EDGE, NOT A LEVEL, and the distinction is the whole bound: success self-limits because the launch restamps the instance out of eligibility, but a FAILING launch under a level trigger -- owner is online -- retries every five seconds for as long as the owner stays up, while an edge bounds it to one attempt per owner-online event. THE REFUSAL ARMS ARE CARRIED BY CONSTRUCTION, not by restatement: both triggers call one shared per-owner body, so persistent-only, owner online, down in fact via the derived read with the pair test, stamp present, launch predates boot, and no boot oracle means restore nothing can never drift apart between the two paths. THE EDGE STATE IS SEEDED BEFORE THE SWEEP, deliberately: seeded after, an owner that comes online in the window between the sweep and the first tick reads as already-online and never fires -- the exact miss this requirement exists to close -- while seeding before can at worst re-attempt an instance the sweep already restored, which the RESTAMPED BIRTH STAMP refuses -- and NOT the down-in-fact arm, which is the arm that reads like the answer and is not: a launch is not the online switch, so a just-restored instance keeps an `offline` record until its bind-shell handshake and still reads as down in fact; what refuses the second attempt is that the launch moved `launched_ms` past the boot instant.

BAROMETER W2 authenticated the DERIVATION path (`shellinfo::shell_pid_provably_dead` runs the pair test) and left the KILL path believing a bare pid, so the same recycled-pid state that the derived read correctly calls a corpse still routes to `taskkill /PID <pid> /T /F` (unix `kill -9`) against whatever unrelated process now wears that number -- and `/T` takes its whole subtree with it, on the user's machine. Proven reachable by probe, not inferred: a live stranger's pid parked beside a foreign birth stamp is killed by `kill_shell_at` while `shell_pid_provably_dead` calls the same pair a corpse. SITE SHAPE IS TWO CHOKEPOINTS, NOT THREE CALL SITES: `shellhost::kill_shell_at` (reached by `close_shell` and the `spt shell teardown` force path) and `shellwake::kill_waker_at` (reached by `launch_shell`, `close_shell`, `stop_watcher`, and the reconciler), both funnelling into the single `kill_shell_pid` taskkill; the gate therefore lands in the two chokepoints and NO caller changes. THE WAKER HALF NEEDED A WRITE-SIDE MINT BEFORE ANY GATE COULD MEAN ANYTHING: `waker.pid` was written bare, and `relay_liveness(live_pid, None)` is HELD by design (pre-stamp records fail toward alive), so a read-side gate there would have returned Held for every record that exists today and every one written tomorrow -- a VACUOUS gate that proves green. The pair is therefore minted in the waker's single existing write as a two-line `waker.pid` (`<pid>\\\\n<birth>`): ONE file, ONE write, so the pair is atomic -- a second file has a torn window in which the pid is on disk and the stamp is not, and that window reads Held, which is the vacuous arm reintroduced as a race. Write and every reader move through ONE shared record/read function pair, mirroring `record_shell_launch`/`read_shell_launch`. FAIL-TOWARD-ALIVE IS THE PARSE ARM TOO: an unparseable record reads None and REFUSES the kill while LEAVING the record, because kill-nothing-and-retire-the-pid-file-anyway orphans a live waker while presenting success -- worse than the defect being fixed. UNPROVEN REFUSES: the destructive arm treats unknown as do-not-fire (consequence asymmetry -- a mis-fire force-kills a stranger's tree, a missed kill leaves our own binary running and observable), which FALSIFIES the shipped unconditional promise that a link-break's force-close always kills and \\\"the binary never survives\\\", so `close_shell`'s step 3, the REQ-SHELL-2 language, the CONTEXT lifecycle line and KNOWN-HAZARDS 7.58 are amended together with the code rather than one comment patched. THE REFUSAL IS LOUD: every declined kill names the reason and the pid on the channel the close path already speaks, and the bounded confirm loop reports a binary that outlived it -- a quiet wrong state is the un-RCA-able one, and the harm-asymmetry argument has to hold in the log and not only in principle. THIS NARROWS THE MIS-FIRE, IT DOES NOT ELIMINATE IT, AND THE TEXT SAYS SO: on Linux `process_started_at` reads /proc/<pid>/stat field 22, which counts CLK_TCK=100 jiffies, so two processes whose starts fall in the SAME 10ms tick carry an identical stamp and the pair cannot separate them. The window closes from ANY recycled pid to A PID RECYCLED INTO THE SAME 10ms TICK AS THE RECORDED START -- which requires our process to die AND the OS to hand its number to a new process inside one tick, a precondition that is its own mitigation. Windows is unaffected (FILETIME, far finer resolution). Measured by hertz on kitsubito; recorded verbatim so nobody re-derives it. THE ASYMMETRY IS WHY THIS IS THE KILL PATH'S SENTENCE TO WRITE: the same predicate with the same imprecision is SAFE on the derivation side and UNSAFE here -- Held means 'stays stale' for a derived read and 'fire the kill' for a destructive one, so only the kill side carries the residual harm and only the kill side has to declare it. Image-path corroboration (which would unify this rule with the rig-side technique in KNOWN-HAZARDS 7.58) is filed past as releases#120, deliberately not taken in a closing milestone. MIGRATION WINDOW, NAMED NOT SILENT: pre-W2 shell records and pre-fix waker records carry no stamp, read Held on existence alone, and keep today's bare-pid kill until their next launch writes a pair. DOWNGRADE DIRECTION, NAMED: an OLD binary reading the NEW two-line `waker.pid` parse-fails to None, which reads as no-pid and refuses the kill -- missed-kill, not mis-fire, the safe polarity.

The restart shape -- record left online over a corpse, no rest edge ever -- is UNREACHABLE FROM THAT TEST BY CONSTRUCTION. The test is not weak; its SETUP SUPPRESSES THE FAILING ARM, so a reader asking whether the cascade is covered gets a true answer to the wrong question. This is the third suppressed-arm instance found in one week, and the pattern is the same each time: a fixture that establishes the precondition the code under test is supposed to establish. 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 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.

After a bounce the stamp stands with nothing standing behind it, so the first `note_success` of ANY kind recomposes an empty latch set to None and clears a fault whose kind this process never learned.

FIX: the stamp carries a SLOT-KEYED sibling map written by the SAME seam that writes the reason, so the sentence and the latches that produced it can never disagree on disk, and the pulse loop seeds its latches from that map at startup BEFORE any tick can report a success. THE KEY IS A LATCH SLOT, NOT A KIND, and the distinction is load-bearing rather than nominal: there are THREE slots against TWO kinds, because the timeout latch is shared cross-kind by the ruled BAROMETER W1 semantics and belongs to no kind at all -- a kind-keyed reading would be re-read later as a per-kind register and gain a fourth key the day a fourth kind appears. THE VOCABULARY IS CLOSED to those three slots, and an unrecognized key is IGNORED AND ANNOUNCED rather than seeded: an unknown slot can only come from a newer binary owning a latch this one has no code to clear, so seeding it would strand a fault that no success could ever recompose away, while dropping it silently would make a rollback that loses a standing fault look identical to a recovery.

THE DISCRIMINATOR IS A WRITE-AHEAD INGEST-INTENT MARKER: the lifecycle persists an expected-ingest record (timestamp + trigger) BEFORE launching the summarizer spawn, a completed ingest CONSUMES it, and a marker still standing past the spawn budget with no corresponding drop positively identifies the killed-at-bound case for that attempt -- no staleness threshold to tune and no guessing. THE ORDERING IS THE PROPERTY, not an implementation detail: a marker written after the spawn returns cannot survive the case it exists to detect, exactly as an intention recorded only after an answer arrives cannot survive an answer that never comes. SURFACING rides where the degraded party is already listening -- at resume/compose, beside the un-ingested-drop warning, saying that a commune was expected and never ingested and that the reader may be resuming stale. The marker is therefore written by the daemon lifecycle and read by the CLI compose path, so its storage must serve both. A killed-at-bound attempt counts on the SOFT timeout budget, never the hard one. Gate: impl -- the marker persisted before the spawn with its timestamp and trigger, consumed on ingest completion, the orphan classified past the budget, the resume/compose surfacing, and the storage readable from the CLI compose seam; unit -- a spawn killed at its bound leaves a standing marker with no drop and classifies as the expected-never-ingested case, a completed ingest leaves NO marker (the pair asserted together, since the orphan row alone passes an implementation that never consumes and would then report every healthy commune as orphaned), a marker whose drop IS present is not classified orphaned, and the write-ahead ORDERING is asserted directly by observing the marker from a spawn that never returns -- a post-spawn write passes every other row and fails this one.\"\r\nrequired_stages = [\"doc\", \"impl\", \"unit\"]  # ACTIVATED BAROMETER W1 at impl+unit (evidence lands here).

The marker has a second surface: `docs-site/src/harness-contract/echo-commune.md` is the HARNESS CONTRACT an adapter author blind-builds against, and there the expectation model is not prose about ourselves -- it is the reason file-presence cannot be the health signal (the #96 discriminator), the thing an author must know to read a COMMUNE_NEVER_INGESTED resume warning, and the context for declaring a sane `invocation_budget_secs`. doc = the \"A bound kill is not a non-zero exit, and it is not silent\" section of that page (the tag sits on it), which states the record-before-spawn expectation, the resume-time surfacing, and the current-state overwrite rule. Untagged it would have rested on nobody deleting it -- the class that let a stale hedge survive a full gate in DOORBELL. EDGE RULED (doyle, my recommendation): CURRENT-STATE ONLY, no history count -- a later successful commune overwrites the marker and the warning stops, because the surface answers \"may I be resuming stale NOW\" and a superseded loss is noise; the killed attempt is still remembered where it belongs, on the soft timeout budget.

CONTEXT.md states it plainly -- a persistent shell is automatically brought online whenever its owner endpoint is online -- and the shipped code honors that across a graceful suspend->wake rest edge ONLY. A machine restart produces no such edge and there is no boot-time restoration at all, so after a reboot every persistent shell on the node stays down until a human runs `relink` by hand, with no surface saying so. Field, HFENDULEAM 2026-08-01: the fleet came up at 01:11 and NOT ONE persistent shell came back; the two instances that did were relaunched by a human at 01:27, sixteen minutes later. TWO INDEPENDENT GATES, both of which must fall or the promise stays broken. GATE 1, no restoration path: the five launch sites all require either an explicit command, a rest edge, or a `wake_command` the adapter may deliberately not declare, and daemon boot starts only the servicehost sweep and the wake reconciler. GATE 2, the stale record blocks the cascade even when an edge DOES arrive: the to_active arm gates on the RECORDED status being offline, and a machine death breaks no link, so the close that would write offline never runs and the record says online over a corpse forever. LEG (a) HEALS THE RECORD TO THE TRUTH, with a BIRTH-STAMPED probe rather than bare pid liveness -- a pid namespace resets at boot, so a corpse pid can be REUSED by an unrelated process, and a reused pid reads alive, makes the derived status read online, and makes `relink` refuse SHELL_ALREADY_ONLINE: the one command that recovers the instance refusing on the very state that is wrong. TWO STAMPS ARE PARKED, NOT ONE, AND THE REASON IS A PLATFORM ASYMMETRY THAT WOULD OTHERWISE SHIP SILENTLY BROKEN ON LINUX: `process_started_at` returns a Windows FILETIME (absolute, comparable across boots) but on Linux returns field 22 of /proc/<pid>/stat, which is JIFFIES SINCE BOOT and resets every boot, so a value recorded before a restart is indistinguishable from a fresh one after it. The NATIVE stamp is therefore used for one question only -- the same-pid-different-process PAIR test within a single boot, mirroring `liveness::relay_liveness` -- and an ABSOLUTE epoch-ms launch stamp is parked beside it for the cross-boot question. LEG (b) IS A ONCE-PER-DAEMON-GENERATION BOOT SWEEP relaunching persistent instances whose owners are online, and its discriminant is THE LAUNCH STAMP PREDATES THE BOOT INSTANT, which preserves the class-c force-kill ruling BY CONSTRUCTION rather than by a second rule: a force-kill during steady-state operation leaves a corpse launched AFTER boot, so it is never spontaneously relaunched and the mid-deploy exe-overwrite hazard that ruling protects is untouched. A NAMED SLACK CONSTANT absorbs boot-instant jitter so a process launched moments after boot is never misclassified as a corpse. Gate: impl -- the two stamps parked at the two production pid-write sites (the census is authoritative: five LAUNCH sites funnel through exactly TWO pid writes), the birth-stamped death probe, the record heal in the daemon-side reconciler guarded on an actual change of the recorded value, the boot-instant helper on both platforms, and the boot sweep with its predates-boot discriminant plus slack; unit -- a reused pid (same pid, different birth stamp) reads GONE where bare-pid liveness reads alive (the row the shipped probe cannot pass), a same-pid-same-birth process reads HELD, the heal writes offline over a stale online record and writes NOTHING when the record already matches the truth (the guard asserted by counting writes, since a heal that rewrites every cycle passes any state-only assertion), a corpse launched BEFORE the boot instant is eligible for restore while one launched AFTER it is NOT (the class-c pair, asserted together since either alone passes an implementation that restores everything or nothing), and an instance whose OWNER is offline is not restored even though its corpse predates boot.\"\r\nrequired_stages = [\"doc\", \"impl\", \"unit\"]  # doc ACTIVATED BAROMETER W2 doc leg (doyle-ruled, this milestone): the CONTEXT.md `persistent` amendment states the boot sweep and its four conjunct gates incl. no-stamp => not restored, which IS this requirement's doc evidence; leaving the stage inactive would have made it evidence the registry cannot see.\r\n\r\n[[requirements]]\r\nid = \"REQ-SHELL-OWNER-ONLINE-RESTORE\"\r\ntitle = \"A `persistent` SHELL WHOSE OWNER ENDPOINT WAS NOT YET ONLINE WHEN THE BOOT SWEEP RAN IS RESTORED WHEN THAT OWNER COMES ONLINE, RATHER THAN STAYING DOWN UNTIL A HUMAN RELINKS IT. ROOT (releases#228): daemons boot before endpoints do, so the boot sweep of REQ-SHELL-PERSISTENT-BOOT-RESTORE correctly SKIPS an owner that is not up yet -- an offline owner is owed nothing -- and then nothing ever revisits it: the sweep is once per daemon generation, and bringup from offline produces no rest edge, so the ADR-0048 cascade never fires either. The shell stays down until a `shell cmd` wakes it or an operator relinks by hand, and whether a given node restart strands its shells is an ordering accident. THE ONCE-NESS IS SCHEDULING, NOT SAFETY (doyle, releases#228, re-measured at head): the `launch_predates_boot` corpse-boot discriminant is what preserves the force-kill ruling, and it is MONOTONE WITHIN A MACHINE BOOT -- every launch path restamps `launched_ms`, a kill never restamps, `boot_ms` is the machine boot instant -- so re-evaluating the conjuncts later in a generation can only refuse MORE, never less. FIX: the reconcile loop carries the SAME per-owner restore body the boot sweep runs, triggered on owner offline->online transitions since the last pass. THE TRIGGER IS AN EDGE, NOT A LEVEL, and the distinction is the whole bound: success self-limits because the launch restamps the instance out of eligibility, but a FAILING launch under a level trigger -- owner is online -- retries every five seconds for as long as the owner stays up, while an edge bounds it to one attempt per owner-online event. THE REFUSAL ARMS ARE CARRIED BY CONSTRUCTION, not by restatement: both triggers call one shared per-owner body, so persistent-only, owner online, down in fact via the derived read with the pair test, stamp present, launch predates boot, and no boot oracle means restore nothing can never drift apart between the two paths. THE EDGE STATE IS SEEDED BEFORE THE SWEEP, deliberately: seeded after, an owner that comes online in the window between the sweep and the first tick reads as already-online and never fires -- the exact miss this requirement exists to close -- while seeding before can at worst re-attempt an instance the sweep already restored, which the RESTAMPED BIRTH STAMP refuses -- and NOT the down-in-fact arm, which is the arm that reads like the answer and is not: a launch is not the online switch, so a just-restored instance keeps an `offline` record until its bind-shell handshake and still reads as down in fact; what refuses the second attempt is that the launch moved `launched_ms` past the boot instant.

BAROMETER W2 authenticated the DERIVATION path (`shellinfo::shell_pid_provably_dead` runs the pair test) and left the KILL path believing a bare pid, so the same recycled-pid state that the derived read correctly calls a corpse still routes to `taskkill /PID <pid> /T /F` (unix `kill -9`) against whatever unrelated process now wears that number -- and `/T` takes its whole subtree with it, on the user's machine. Proven reachable by probe, not inferred: a live stranger's pid parked beside a foreign birth stamp is killed by `kill_shell_at` while `shell_pid_provably_dead` calls the same pair a corpse. SITE SHAPE IS TWO CHOKEPOINTS, NOT THREE CALL SITES: `shellhost::kill_shell_at` (reached by `close_shell` and the `spt shell teardown` force path) and `shellwake::kill_waker_at` (reached by `launch_shell`, `close_shell`, `stop_watcher`, and the reconciler), both funnelling into the single `kill_shell_pid` taskkill; the gate therefore lands in the two chokepoints and NO caller changes. THE WAKER HALF NEEDED A WRITE-SIDE MINT BEFORE ANY GATE COULD MEAN ANYTHING: `waker.pid` was written bare, and `relay_liveness(live_pid, None)` is HELD by design (pre-stamp records fail toward alive), so a read-side gate there would have returned Held for every record that exists today and every one written tomorrow -- a VACUOUS gate that proves green. The pair is therefore minted in the waker's single existing write as a two-line `waker.pid` (`<pid>\\\\n<birth>`): ONE file, ONE write, so the pair is atomic -- a second file has a torn window in which the pid is on disk and the stamp is not, and that window reads Held, which is the vacuous arm reintroduced as a race. Write and every reader move through ONE shared record/read function pair, mirroring `record_shell_launch`/`read_shell_launch`. FAIL-TOWARD-ALIVE IS THE PARSE ARM TOO: an unparseable record reads None and REFUSES the kill while LEAVING the record, because kill-nothing-and-retire-the-pid-file-anyway orphans a live waker while presenting success -- worse than the defect being fixed. UNPROVEN REFUSES: the destructive arm treats unknown as do-not-fire (consequence asymmetry -- a mis-fire force-kills a stranger's tree, a missed kill leaves our own binary running and observable), which FALSIFIES the shipped unconditional promise that a link-break's force-close always kills and \\\"the binary never survives\\\", so `close_shell`'s step 3, the REQ-SHELL-2 language, the CONTEXT lifecycle line and KNOWN-HAZARDS 7.58 are amended together with the code rather than one comment patched. THE REFUSAL IS LOUD: every declined kill names the reason and the pid on the channel the close path already speaks, and the bounded confirm loop reports a binary that outlived it -- a quiet wrong state is the un-RCA-able one, and the harm-asymmetry argument has to hold in the log and not only in principle. THIS NARROWS THE MIS-FIRE, IT DOES NOT ELIMINATE IT, AND THE TEXT SAYS SO: on Linux `process_started_at` reads /proc/<pid>/stat field 22, which counts CLK_TCK=100 jiffies, so two processes whose starts fall in the SAME 10ms tick carry an identical stamp and the pair cannot separate them. The window closes from ANY recycled pid to A PID RECYCLED INTO THE SAME 10ms TICK AS THE RECORDED START -- which requires our process to die AND the OS to hand its number to a new process inside one tick, a precondition that is its own mitigation. Windows is unaffected (FILETIME, far finer resolution). Measured by hertz on kitsubito; recorded verbatim so nobody re-derives it. THE ASYMMETRY IS WHY THIS IS THE KILL PATH'S SENTENCE TO WRITE: the same predicate with the same imprecision is SAFE on the derivation side and UNSAFE here -- Held means 'stays stale' for a derived read and 'fire the kill' for a destructive one, so only the kill side carries the residual harm and only the kill side has to declare it. Image-path corroboration (which would unify this rule with the rig-side technique in KNOWN-HAZARDS 7.58) is filed past as releases#120, deliberately not taken in a closing milestone. MIGRATION WINDOW, NAMED NOT SILENT: pre-W2 shell records and pre-fix waker records carry no stamp, read Held on existence alone, and keep today's bare-pid kill until their next launch writes a pair.

THE COVERAGE GAP IS THE HAZARD'S OWN SUBJECT, and it must be named here so no future reader mistakes the cascade test for coverage of this class: `rest_edges_cascade_shells_with_divergence` (spt-daemon resting.rs) is the cascade's only coverage and it walks the graceful path ONLY -- it SUSPENDS FIRST, and the suspend edge WRITES the offline record, so by the time the wake edge fires the instance is already in exactly the state the to_active arm requires. The restart shape -- record left online over a corpse, no rest edge ever -- is UNREACHABLE FROM THAT TEST BY CONSTRUCTION. The test is not weak; its SETUP SUPPRESSES THE FAILING ARM, so a reader asking whether the cascade is covered gets a true answer to the wrong question. This is the third suppressed-arm instance found in one week, and the pattern is the same each time: a fixture that establishes the precondition the code under test is supposed to establish. 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 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.

After a bounce the stamp stands with nothing standing behind it, so the first `note_success` of ANY kind recomposes an empty latch set to None and clears a fault whose kind this process never learned. THE PER-KIND SEPARATION BAROMETER W1 BUILT IS THEREFORE UNDONE BY A RESTART: one working ingest erases a standing turn defect it says nothing about, which is precisely the vouching REQ-PSYCHE-HARD-BUDGET-PER-KIND exists to forbid -- the defect does not lose information at the margin, it re-opens a closed hazard. FIX: the stamp carries a SLOT-KEYED sibling map written by the SAME seam that writes the reason, so the sentence and the latches that produced it can never disagree on disk, and the pulse loop seeds its latches from that map at startup BEFORE any tick can report a success. THE KEY IS A LATCH SLOT, NOT A KIND, and the distinction is load-bearing rather than nominal: there are THREE slots against TWO kinds, because the timeout latch is shared cross-kind by the ruled BAROMETER W1 semantics and belongs to no kind at all -- a kind-keyed reading would be re-read later as a per-kind register and gain a fourth key the day a fourth kind appears. THE VOCABULARY IS CLOSED to those three slots, and an unrecognized key is IGNORED AND ANNOUNCED rather than seeded: an unknown slot can only come from a newer binary owning a latch this one has no code to clear, so seeding it would strand a fault that no success could ever recompose away, while dropping it silently would make a rollback that loses a standing fault look identical to a recovery. A PRE-#115 STAMP CARRIES NO SLOTS AND SEEDS NOTHING, deliberately: its kind is genuinely unrecoverable, and the honest behaviour for an unknown-kind fault is the one that shipped, where any success clears it (REQ-PSYCHE-STAMP-CLEAR-ANY-SUCCESS) -- inventing a kind for it would be worse than forgetting one. `reason` stays BYTE-IDENTICAL, and the map is serde-default plus skip-when-empty so a stamp with no standing latches serializes byte-identically to the pre-#115 shape; N-1 holds in BOTH directions, the old-binary/new-record leg proven by a MEASURED absence of any live deny_unknown_fields attribute repo-wide (zero, on this struct and on InfoJson alike) rather than by assuming serde's default.

EDGE RULED (doyle, my recommendation): CURRENT-STATE ONLY, no history count -- a later successful commune overwrites the marker and the warning stops, because the surface answers \"may I be resuming stale NOW\" and a superseded loss is noise; the killed attempt is still remembered where it belongs, on the soft timeout budget. MINTED BAROMETER W1 (todlando, 2026-08-02), releases#96 -- inactive-first.

CONTEXT.md states it plainly -- a persistent shell is automatically brought online whenever its owner endpoint is online -- and the shipped code honors that across a graceful suspend->wake rest edge ONLY. A machine restart produces no such edge and there is no boot-time restoration at all, so after a reboot every persistent shell on the node stays down until a human runs `relink` by hand, with no surface saying so. Field, HFENDULEAM 2026-08-01: the fleet came up at 01:11 and NOT ONE persistent shell came back; the two instances that did were relaunched by a human at 01:27, sixteen minutes later. TWO INDEPENDENT GATES, both of which must fall or the promise stays broken. GATE 1, no restoration path: the five launch sites all require either an explicit command, a rest edge, or a `wake_command` the adapter may deliberately not declare, and daemon boot starts only the servicehost sweep and the wake reconciler. GATE 2, the stale record blocks the cascade even when an edge DOES arrive: the to_active arm gates on the RECORDED status being offline, and a machine death breaks no link, so the close that would write offline never runs and the record says online over a corpse forever. LEG (a) HEALS THE RECORD TO THE TRUTH, with a BIRTH-STAMPED probe rather than bare pid liveness -- a pid namespace resets at boot, so a corpse pid can be REUSED by an unrelated process, and a reused pid reads alive, makes the derived status read online, and makes `relink` refuse SHELL_ALREADY_ONLINE: the one command that recovers the instance refusing on the very state that is wrong. TWO STAMPS ARE PARKED, NOT ONE, AND THE REASON IS A PLATFORM ASYMMETRY THAT WOULD OTHERWISE SHIP SILENTLY BROKEN ON LINUX: `process_started_at` returns a Windows FILETIME (absolute, comparable across boots) but on Linux returns field 22 of /proc/<pid>/stat, which is JIFFIES SINCE BOOT and resets every boot, so a value recorded before a restart is indistinguishable from a fresh one after it. The NATIVE stamp is therefore used for one question only -- the same-pid-different-process PAIR test within a single boot, mirroring `liveness::relay_liveness` -- and an ABSOLUTE epoch-ms launch stamp is parked beside it for the cross-boot question. LEG (b) IS A ONCE-PER-DAEMON-GENERATION BOOT SWEEP relaunching persistent instances whose owners are online, and its discriminant is THE LAUNCH STAMP PREDATES THE BOOT INSTANT, which preserves the class-c force-kill ruling BY CONSTRUCTION rather than by a second rule: a force-kill during steady-state operation leaves a corpse launched AFTER boot, so it is never spontaneously relaunched and the mid-deploy exe-overwrite hazard that ruling protects is untouched. A NAMED SLACK CONSTANT absorbs boot-instant jitter so a process launched moments after boot is never misclassified as a corpse. Gate: impl -- the two stamps parked at the two production pid-write sites (the census is authoritative: five LAUNCH sites funnel through exactly TWO pid writes), the birth-stamped death probe, the record heal in the daemon-side reconciler guarded on an actual change of the recorded value, the boot-instant helper on both platforms, and the boot sweep with its predates-boot discriminant plus slack; unit -- a reused pid (same pid, different birth stamp) reads GONE where bare-pid liveness reads alive (the row the shipped probe cannot pass), a same-pid-same-birth process reads HELD, the heal writes offline over a stale online record and writes NOTHING when the record already matches the truth (the guard asserted by counting writes, since a heal that rewrites every cycle passes any state-only assertion), a corpse launched BEFORE the boot instant is eligible for restore while one launched AFTER it is NOT (the class-c pair, asserted together since either alone passes an implementation that restores everything or nothing), and an instance whose OWNER is offline is not restored even though its corpse predates boot.\"\r\nrequired_stages = [\"doc\", \"impl\", \"unit\"]  # doc ACTIVATED BAROMETER W2 doc leg (doyle-ruled, this milestone): the CONTEXT.md `persistent` amendment states the boot sweep and its four conjunct gates incl. no-stamp => not restored, which IS this requirement's doc evidence; leaving the stage inactive would have made it evidence the registry cannot see.\r\n\r\n[[requirements]]\r\nid = \"REQ-SHELL-OWNER-ONLINE-RESTORE\"\r\ntitle = \"A `persistent` SHELL WHOSE OWNER ENDPOINT WAS NOT YET ONLINE WHEN THE BOOT SWEEP RAN IS RESTORED WHEN THAT OWNER COMES ONLINE, RATHER THAN STAYING DOWN UNTIL A HUMAN RELINKS IT. ROOT (releases#228): daemons boot before endpoints do, so the boot sweep of REQ-SHELL-PERSISTENT-BOOT-RESTORE correctly SKIPS an owner that is not up yet -- an offline owner is owed nothing -- and then nothing ever revisits it: the sweep is once per daemon generation, and bringup from offline produces no rest edge, so the ADR-0048 cascade never fires either. The shell stays down until a `shell cmd` wakes it or an operator relinks by hand, and whether a given node restart strands its shells is an ordering accident. THE ONCE-NESS IS SCHEDULING, NOT SAFETY (doyle, releases#228, re-measured at head): the `launch_predates_boot` corpse-boot discriminant is what preserves the force-kill ruling, and it is MONOTONE WITHIN A MACHINE BOOT -- every launch path restamps `launched_ms`, a kill never restamps, `boot_ms` is the machine boot instant -- so re-evaluating the conjuncts later in a generation can only refuse MORE, never less. FIX: the reconcile loop carries the SAME per-owner restore body the boot sweep runs, triggered on owner offline->online transitions since the last pass. THE TRIGGER IS AN EDGE, NOT A LEVEL, and the distinction is the whole bound: success self-limits because the launch restamps the instance out of eligibility, but a FAILING launch under a level trigger -- owner is online -- retries every five seconds for as long as the owner stays up, while an edge bounds it to one attempt per owner-online event. THE REFUSAL ARMS ARE CARRIED BY CONSTRUCTION, not by restatement: both triggers call one shared per-owner body, so persistent-only, owner online, down in fact via the derived read with the pair test, stamp present, launch predates boot, and no boot oracle means restore nothing can never drift apart between the two paths. THE EDGE STATE IS SEEDED BEFORE THE SWEEP, deliberately: seeded after, an owner that comes online in the window between the sweep and the first tick reads as already-online and never fires -- the exact miss this requirement exists to close -- while seeding before can at worst re-attempt an instance the sweep already restored, which the RESTAMPED BIRTH STAMP refuses -- and NOT the down-in-fact arm, which is the arm that reads like the answer and is not: a launch is not the online switch, so a just-restored instance keeps an `offline` record until its bind-shell handshake and still reads as down in fact; what refuses the second attempt is that the launch moved `launched_ms` past the boot instant. Each trigger names ITSELF in its event line, because the field evidence that diagnosed this ticket was a count of those events and a shared name would leave the next investigation unable to say which trigger fired.

BAROMETER W2 authenticated the DERIVATION path (`shellinfo::shell_pid_provably_dead` runs the pair test) and left the KILL path believing a bare pid, so the same recycled-pid state that the derived read correctly calls a corpse still routes to `taskkill /PID <pid> /T /F` (unix `kill -9`) against whatever unrelated process now wears that number -- and `/T` takes its whole subtree with it, on the user's machine. Proven reachable by probe, not inferred: a live stranger's pid parked beside a foreign birth stamp is killed by `kill_shell_at` while `shell_pid_provably_dead` calls the same pair a corpse. SITE SHAPE IS TWO CHOKEPOINTS, NOT THREE CALL SITES: `shellhost::kill_shell_at` (reached by `close_shell` and the `spt shell teardown` force path) and `shellwake::kill_waker_at` (reached by `launch_shell`, `close_shell`, `stop_watcher`, and the reconciler), both funnelling into the single `kill_shell_pid` taskkill; the gate therefore lands in the two chokepoints and NO caller changes. THE WAKER HALF NEEDED A WRITE-SIDE MINT BEFORE ANY GATE COULD MEAN ANYTHING: `waker.pid` was written bare, and `relay_liveness(live_pid, None)` is HELD by design (pre-stamp records fail toward alive), so a read-side gate there would have returned Held for every record that exists today and every one written tomorrow -- a VACUOUS gate that proves green. The pair is therefore minted in the waker's single existing write as a two-line `waker.pid` (`<pid>\\\\n<birth>`): ONE file, ONE write, so the pair is atomic -- a second file has a torn window in which the pid is on disk and the stamp is not, and that window reads Held, which is the vacuous arm reintroduced as a race. Write and every reader move through ONE shared record/read function pair, mirroring `record_shell_launch`/`read_shell_launch`. FAIL-TOWARD-ALIVE IS THE PARSE ARM TOO: an unparseable record reads None and REFUSES the kill while LEAVING the record, because kill-nothing-and-retire-the-pid-file-anyway orphans a live waker while presenting success -- worse than the defect being fixed. UNPROVEN REFUSES: the destructive arm treats unknown as do-not-fire (consequence asymmetry -- a mis-fire force-kills a stranger's tree, a missed kill leaves our own binary running and observable), which FALSIFIES the shipped unconditional promise that a link-break's force-close always kills and \\\"the binary never survives\\\", so `close_shell`'s step 3, the REQ-SHELL-2 language, the CONTEXT lifecycle line and KNOWN-HAZARDS 7.58 are amended together with the code rather than one comment patched. THE REFUSAL IS LOUD: every declined kill names the reason and the pid on the channel the close path already speaks, and the bounded confirm loop reports a binary that outlived it -- a quiet wrong state is the un-RCA-able one, and the harm-asymmetry argument has to hold in the log and not only in principle. THIS NARROWS THE MIS-FIRE, IT DOES NOT ELIMINATE IT, AND THE TEXT SAYS SO: on Linux `process_started_at` reads /proc/<pid>/stat field 22, which counts CLK_TCK=100 jiffies, so two processes whose starts fall in the SAME 10ms tick carry an identical stamp and the pair cannot separate them. The window closes from ANY recycled pid to A PID RECYCLED INTO THE SAME 10ms TICK AS THE RECORDED START -- which requires our process to die AND the OS to hand its number to a new process inside one tick, a precondition that is its own mitigation. Windows is unaffected (FILETIME, far finer resolution). Measured by hertz on kitsubito; recorded verbatim so nobody re-derives it. THE ASYMMETRY IS WHY THIS IS THE KILL PATH'S SENTENCE TO WRITE: the same predicate with the same imprecision is SAFE on the derivation side and UNSAFE here -- Held means 'stays stale' for a derived read and 'fire the kill' for a destructive one, so only the kill side carries the residual harm and only the kill side has to declare it. Image-path corroboration (which would unify this rule with the rig-side technique in KNOWN-HAZARDS 7.58) is filed past as releases#120, deliberately not taken in a closing milestone. MIGRATION WINDOW, NAMED NOT SILENT: pre-W2 shell records and pre-fix waker records carry no stamp, read Held on existence alone, and keep today's bare-pid kill until their next launch writes a pair. DOWNGRADE DIRECTION, NAMED: an OLD binary reading the NEW two-line `waker.pid` parse-fails to None, which reads as no-pid and refuses the kill -- missed-kill, not mis-fire, the safe polarity. Gate: impl -- the pair gate in both chokepoints, the shared waker record/read pair with the two-line format, every waker.pid reader moved onto it, the loud refusal arms, and the confirm-loop survivor report; unit -- a recycled pid (live, birth mismatch) is NOT killed where the shipped code kills it, a genuine own-process pair (Held) IS still killed so the gate is not vacuous, an absent stamp keeps the pre-stamp kill, Unproven refuses, an unparseable waker record refuses AND leaves the record in place (asserted together, since retire-anyway passes a kill-count assertion alone), and the refusal is observable rather than silent; int -- hertz's probe inverted: a live stranger parked beside a foreign stamp SURVIVES `kill_shell_at` while `shell_pid_provably_dead` still calls the pair a corpse (the control), with the victim checked through `try_wait` on the held handle rather than a pid-existence probe, which reads alive for an already-killed process while the handle is open.\"\r\nrequired_stages = [\"doc\", \"impl\", \"unit\", \"int\"]  # ACTIVATED BAROMETER W2 reopen in the commit landing the evidence. doc = the KNOWN-HAZARDS 7.58 amend this fix carries (doyle's rider: the entry was scoped TEST-only and that scoping went false the moment the product defect existed, so the de-scope is a mint-time answer, not an assembly-time one).

Distinct from REQ-HAZARD-SHELL-STALE-ONLINE, which governs a force-kill DURING operation: this is a different trigger with a different safe remedy, and conflating them is how the restart class stays invisible. THE COVERAGE GAP IS THE HAZARD'S OWN SUBJECT, and it must be named here so no future reader mistakes the cascade test for coverage of this class: `rest_edges_cascade_shells_with_divergence` (spt-daemon resting.rs) is the cascade's only coverage and it walks the graceful path ONLY -- it SUSPENDS FIRST, and the suspend edge WRITES the offline record, so by the time the wake edge fires the instance is already in exactly the state the to_active arm requires. The restart shape -- record left online over a corpse, no rest edge ever -- is UNREACHABLE FROM THAT TEST BY CONSTRUCTION. The test is not weak; its SETUP SUPPRESSES THE FAILING ARM, so a reader asking whether the cascade is covered gets a true answer to the wrong question. This is the third suppressed-arm instance found in one week, and the pattern is the same each time: a fixture that establishes the precondition the code under test is supposed to establish. 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 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.

A shell force-killed *during* this boot is launched after it, can never satisfy the predicate, and so is never spontaneously relaunched — the deploy/quarantine ruling of KNOWN-HAZARDS 2.6 preserved by construction. <!-- [doc->REQ-SHELL-PERSISTENT-BOOT-RESTORE] -->\r\n  **Daemons boot before endpoints do, so the sweep is not the only trigger** (releases#228): an owner that is not yet online when the sweep runs is skipped by that very conjunct, and — the sweep being once per daemon generation, and bringup from offline emitting no rest edge — nothing revisited it, so its shells stayed down until a human relinked. The reconcile loop therefore runs the **same four conditions** for every owner that has gone **offline→online since the last pass**. The trigger is that **edge, never the level “the owner is online”**: a successful restore restamps itself out of eligibility, but a *failing* launch under a level trigger would be retried every reconcile tick for as long as the owner stayed up, where the edge bounds it to one attempt per owner-online event. Re-evaluating later in a generation can only refuse **more**, never less — every launch path restamps the birth stamp, a kill never does, and the boot instant is fixed for the machine boot — so the force-kill ruling above is preserved identically on the second trigger. <!-- [doc->REQ-SHELL-OWNER-ONLINE-RESTORE] -->\r\n- **`wake_command`** (template): a long-running **wake-watcher** process spt-core runs *while the shell is offline* **and eligible** (the eligibility rule is below — an offline instance sitting on a same-boot corpse arms no watcher). Its sole job is to fire a wake. It runs on the **shell's node** (where the platform wake-event originates — e.g. interacting with a \"shut-down\" avatar). Covers \"owner is down, wake it from outside.\"\r\n\r\n**Online/offline are mutually-exclusive processes:** online ⇒ the shell binary runs (no watcher); offline ⇒ the wake-watcher runs (no shell binary). spt-core flips between them. **Offline does not by itself arm the watcher — a third outcome exists** (BAROMETER W2, releases#78): an instance that is offline over a **corpse launched during this boot** (a force-kill, a crash) is deliberately held out of watcher eligibility, so *neither* process runs until recovery is demanded — `relink`, or a `shell cmd` that wakes. Eligibility is recorded-`offline` **AND** (no corpse, **or** the corpse's launch predates the boot instant); an instance whose corpse cannot be dated — no birth stamp, or no boot oracle on the platform — is treated as ineligible rather than guessed at. Only a cleanly-closed instance and a **restart casualty** arm a watcher. The reason is the deploy case: on Windows an operator kills a shell precisely to free its exe for overwrite, and a watcher armed there would re-lock the file under them.\r\n\r\n**Exit-opcode supervision:** the wake-watcher exiting with the **wake opcode** → spt-core runs the wake resolution (below) and brings the shell online. Any *other* exit (crash) → respawn the watcher with **exponential backoff + eventual give-up** (until next shell activity) — crash-bug safety. One watcher per offline shell instance.\r\n\r\n**Wake resolution (state-keyed):** find any *reachable* instance of the owner endpoint on the subnet, then —\r","startLine":387,"lineNumbers":[387,388,389,390,391,392,393,394,395,396,397,398,399]},"fileSize":353477,"meta":{"source":{"type":"path","value":"C:\\Users\\decid\\Documents\\projects\\spt-core\\.worktrees\\287-shellrestore\\CONTEXT.md"},"truncation":{"direction":"head","truncatedBy":"lines","totalLines":1268,"totalBytes":5135,"outputLines":13,"outputBytes":5135,"shownRange":{"start":387,"end":399},"nextOffset":400}}},"isError":false,"timestamp":1788999562192}}

BAROMETER W2 authenticated the DERIVATION path (`shellinfo::shell_pid_provably_dead` runs the pair test) and left the KILL path believing a bare pid, so the same recycled-pid state that the derived read correctly calls a corpse still routes to `taskkill /PID <pid> /T /F` (unix `kill -9`) against whatever unrelated process now wears that number -- and `/T` takes its whole subtree with it, on the user's machine. Proven reachable by probe, not inferred: a live stranger's pid parked beside a foreign birth stamp is killed by `kill_shell_at` while `shell_pid_provably_dead` calls the same pair a corpse. SITE SHAPE IS TWO CHOKEPOINTS, NOT THREE CALL SITES: `shellhost::kill_shell_at` (reached by `close_shell` and the `spt shell teardown` force path) and `shellwake::kill_waker_at` (reached by `launch_shell`, `close_shell`, `stop_watcher`, and the reconciler), both funnelling into the single `kill_shell_pid` taskkill; the gate therefore lands in the two chokepoints and NO caller changes. THE WAKER HALF NEEDED A WRITE-SIDE MINT BEFORE ANY GATE COULD MEAN ANYTHING: `waker.pid` was written bare, and `relay_liveness(live_pid, None)` is HELD by design (pre-stamp records fail toward alive), so a read-side gate there would have returned Held for every record that exists today and every one written tomorrow -- a VACUOUS gate that proves green. The pair is therefore minted in the waker's single existing write as a two-line `waker.pid` (`<pid>\\\\n<birth>`): ONE file, ONE write, so the pair is atomic -- a second file has a torn window in which the pid is on disk and the stamp is not, and that window reads Held, which is the vacuous arm reintroduced as a race. Write and every reader move through ONE shared record/read function pair, mirroring `record_shell_launch`/`read_shell_launch`. FAIL-TOWARD-ALIVE IS THE PARSE ARM TOO: an unparseable record reads None and REFUSES the kill while LEAVING the record, because kill-nothing-and-retire-the-pid-file-anyway orphans a live waker while presenting success -- worse than the defect being fixed. UNPROVEN REFUSES: the destructive arm treats unknown as do-not-fire (consequence asymmetry -- a mis-fire force-kills a stranger's tree, a missed kill leaves our own binary running and observable), which FALSIFIES the shipped unconditional promise that a link-break's force-close always kills and \\\"the binary never survives\\\", so `close_shell`'s step 3, the REQ-SHELL-2 language, the CONTEXT lifecycle line and KNOWN-HAZARDS 7.58 are amended together with the code rather than one comment patched. THE REFUSAL IS LOUD: every declined kill names the reason and the pid on the channel the close path already speaks, and the bounded confirm loop reports a binary that outlived it -- a quiet wrong state is the un-RCA-able one, and the harm-asymmetry argument has to hold in the log and not only in principle. THIS NARROWS THE MIS-FIRE, IT DOES NOT ELIMINATE IT, AND THE TEXT SAYS SO: on Linux `process_started_at` reads /proc/<pid>/stat field 22, which counts CLK_TCK=100 jiffies, so two processes whose starts fall in the SAME 10ms tick carry an identical stamp and the pair cannot separate them. The window closes from ANY recycled pid to A PID RECYCLED INTO THE SAME 10ms TICK AS THE RECORDED START -- which requires our process to die AND the OS to hand its number to a new process inside one tick, a precondition that is its own mitigation. Windows is unaffected (FILETIME, far finer resolution). Measured by hertz on kitsubito; recorded verbatim so nobody re-derives it. THE ASYMMETRY IS WHY THIS IS THE KILL PATH'S SENTENCE TO WRITE: the same predicate with the same imprecision is SAFE on the derivation side and UNSAFE here -- Held means 'stays stale' for a derived read and 'fire the kill' for a destructive one, so only the kill side carries the residual harm and only the kill side has to declare it. Image-path corroboration (which would unify this rule with the rig-side technique in KNOWN-HAZARDS 7.58) is filed past as releases#120, deliberately not taken in a closing milestone. MIGRATION WINDOW, NAMED NOT SILENT: pre-W2 shell records and pre-fix waker records carry no stamp, read Held on existence alone, and keep today's bare-pid kill until their next launch writes a pair. DOWNGRADE DIRECTION, NAMED: an OLD binary reading the NEW two-line `waker.pid` parse-fails to None, which reads as no-pid and refuses the kill -- missed-kill, not mis-fire, the safe polarity. Gate: impl -- the pair gate in both chokepoints, the shared waker record/read pair with the two-line format, every waker.pid reader moved onto it, the loud refusal arms, and the confirm-loop survivor report; unit -- a recycled pid (live, birth mismatch) is NOT killed where the shipped code kills it, a genuine own-process pair (Held) IS still killed so the gate is not vacuous, an absent stamp keeps the pre-stamp kill, Unproven refuses, an unparseable waker record refuses AND leaves the record in place (asserted together, since retire-anyway passes a kill-count assertion alone), and the refusal is observable rather than silent; int -- hertz's probe inverted: a live stranger parked beside a foreign stamp SURVIVES `kill_shell_at` while `shell_pid_provably_dead` still calls the pair a corpse (the control), with the victim checked through `try_wait` on the held handle rather than a pid-existence probe, which reads alive for an already-killed process while the handle is open.\"\n\n4176:\n4177:[[requirements]]\n4178:id = \"REQ-HAZARD-RESTART-STRANDS-PERSISTENT-SHELLS\"\n4179:title = \"A daemon-only or machine restart must not strand persistent shells.

CONTEXT.md states it plainly -- a persistent shell is automatically brought online whenever its owner endpoint is online -- and the shipped code honors that across a graceful suspend->wake rest edge ONLY. A machine restart produces no such edge and there is no boot-time restoration at all, so after a reboot every persistent shell on the node stays down until a human runs `relink` by hand, with no surface saying so. Field, HFENDULEAM 2026-08-01: the fleet came up at 01:11 and NOT ONE persistent shell came back; the two instances that did were relaunched by a human at 01:27, sixteen minutes later. TWO INDEPENDENT GATES, both of which must fall or the promise stays broken. GATE 1, no restoration path: the five launch sites all require either an explicit command, a rest edge, or a `wake_command` the adapter may deliberately not declare, and daemon boot starts only the servicehost sweep and the wake reconciler. GATE 2, the stale record blocks the cascade even when an edge DOES arrive: the to_active arm gates on the RECORDED status being offline, and a machine death breaks no link, so the close that would write offline never runs and the record says online over a corpse forever. LEG (a) HEALS THE RECORD TO THE TRUTH, with a BIRTH-STAMPED probe rather than bare pid liveness -- a pid namespace resets at boot, so a corpse pid can be REUSED by an unrelated process, and a reused pid reads alive, makes the derived status read online, and makes `relink` refuse SHELL_ALREADY_ONLINE: the one command that recovers the instance refusing on the very state that is wrong. TWO STAMPS ARE PARKED, NOT ONE, AND THE REASON IS A PLATFORM ASYMMETRY THAT WOULD OTHERWISE SHIP SILENTLY BROKEN ON LINUX: `process_started_at` returns a Windows FILETIME (absolute, comparable across boots) but on Linux returns field 22 of /proc/<pid>/stat, which is JIFFIES SINCE BOOT and resets every boot, so a value recorded before a restart is indistinguishable from a fresh one after it. The NATIVE stamp is therefore used for one question only -- the same-pid-different-process PAIR test within a single boot, mirroring `liveness::relay_liveness` -- and an ABSOLUTE epoch-ms launch stamp is parked beside it for the cross-boot question. LEG (b) IS A ONCE-PER-DAEMON-GENERATION BOOT SWEEP relaunching persistent instances whose owners are online, and its discriminant is THE LAUNCH STAMP PREDATES THE BOOT INSTANT, which preserves the class-c force-kill ruling BY CONSTRUCTION rather than by a second rule: a force-kill during steady-state operation leaves a corpse launched AFTER boot, so it is never spontaneously relaunched and the mid-deploy exe-overwrite hazard that ruling protects is untouched. A NAMED SLACK CONSTANT absorbs boot-instant jitter so a process launched moments after boot is never misclassified as a corpse. Gate: impl -- the two stamps parked at the two production pid-write sites (the census is authoritative: five LAUNCH sites funnel through exactly TWO pid writes), the birth-stamped death probe, the record heal in the daemon-side reconciler guarded on an actual change of the recorded value, the boot-instant helper on both platforms, and the boot sweep with its predates-boot discriminant plus slack; unit -- a reused pid (same pid, different birth stamp) reads GONE where bare-pid liveness reads alive (the row the shipped probe cannot pass), a same-pid-same-birth process reads HELD, the heal writes offline over a stale online record and writes NOTHING when the record already matches the truth (the guard asserted by counting writes, since a heal that rewrites every cycle passes any state-only assertion), a corpse launched BEFORE the boot instant is eligible for restore while one launched AFTER it is NOT (the class-c pair, asserted together since either alone passes an implementation that restores everything or nothing), and an instance whose OWNER is offline is not restored even though its corpse predates boot.\"\n-4155|required_stages = [\"doc\", \"impl\", \"unit\"]  # doc ACTIVATED BAROMETER W2 doc leg (doyle-ruled, this milestone): the CONTEXT.md `persistent` amendment states the boot sweep and its four conjunct gates incl. no-stamp => not restored, which IS this requirement's doc evidence; leaving the stage inactive would have made it evidence the registry cannot see.\n+4154|title = \"Persistent shells are restored on each daemon-generation boot sweep whenever their owner is online and they are down in fact, regardless of machine boot time or recorded launch age (releases#287 operator ruling).

ROOT (releases#228): daemons boot before endpoints do, so the boot sweep of REQ-SHELL-PERSISTENT-BOOT-RESTORE correctly SKIPS an owner that is not up yet -- an offline owner is owed nothing -- and then nothing ever revisits it: the sweep is once per daemon generation, and bringup from offline produces no rest edge, so the ADR-0048 cascade never fires either. The shell stays down until a `shell cmd` wakes it or an operator relinks by hand, and whether a given node restart strands its shells is an ordering accident. THE ONCE-NESS IS SCHEDULING, NOT SAFETY (doyle, releases#228, re-measured at head): the `launch_predates_boot` corpse-boot discriminant is what preserves the force-kill ruling, and it is MONOTONE WITHIN A MACHINE BOOT -- every launch path restamps `launched_ms`, a kill never restamps, `boot_ms` is the machine boot instant -- so re-evaluating the conjuncts later in a generation can only refuse MORE, never less. FIX: the reconcile loop carries the SAME per-owner restore body the boot sweep runs, triggered on owner offline->online transitions since the last pass. THE TRIGGER IS AN EDGE, NOT A LEVEL, and the distinction is the whole bound: success self-limits because the launch restamps the instance out of eligibility, but a FAILING launch under a level trigger -- owner is online -- retries every five seconds for as long as the owner stays up, while an edge bounds it to one attempt per owner-online event. THE REFUSAL ARMS ARE CARRIED BY CONSTRUCTION, not by restatement: both triggers call one shared per-owner body, so persistent-only, owner online, down in fact via the derived read with the pair test, stamp present, launch predates boot, and no boot oracle means restore nothing can never drift apart between the two paths. THE EDGE STATE IS SEEDED BEFORE THE SWEEP, deliberately: seeded after, an owner that comes online in the window between the sweep and the first tick reads as already-online and never fires -- the exact miss this requirement exists to close -- while seeding before can at worst re-attempt an instance the sweep already restored, which the RESTAMPED BIRTH STAMP refuses -- and NOT the down-in-fact arm, which is the arm that reads like the answer and is not: a launch is not the online switch, so a just-restored instance keeps an `offline` record until its bind-shell handshake and still reads as down in fact; what refuses the second attempt is that the launch moved `launched_ms` past the boot instant.

BAROMETER W2 authenticated the DERIVATION path (`shellinfo::shell_pid_provably_dead` runs the pair test) and left the KILL path believing a bare pid, so the same recycled-pid state that the derived read correctly calls a corpse still routes to `taskkill /PID <pid> /T /F` (unix `kill -9`) against whatever unrelated process now wears that number -- and `/T` takes its whole subtree with it, on the user's machine. Proven reachable by probe, not inferred: a live stranger's pid parked beside a foreign birth stamp is killed by `kill_shell_at` while `shell_pid_provably_dead` calls the same pair a corpse. SITE SHAPE IS TWO CHOKEPOINTS, NOT THREE CALL SITES: `shellhost::kill_shell_at` (reached by `close_shell` and the `spt shell teardown` force path) and `shellwake::kill_waker_at` (reached by `launch_shell`, `close_shell`, `stop_watcher`, and the reconciler), both funnelling into the single `kill_shell_pid` taskkill; the gate therefore lands in the two chokepoints and NO caller changes. THE WAKER HALF NEEDED A WRITE-SIDE MINT BEFORE ANY GATE COULD MEAN ANYTHING: `waker.pid` was written bare, and `relay_liveness(live_pid, None)` is HELD by design (pre-stamp records fail toward alive), so a read-side gate there would have returned Held for every record that exists today and every one written tomorrow -- a VACUOUS gate that proves green. The pair is therefore minted in the waker's single existing write as a two-line `waker.pid` (`<pid>\\\\n<birth>`): ONE file, ONE write, so the pair is atomic -- a second file has a torn window in which the pid is on disk and the stamp is not, and that window reads Held, which is the vacuous arm reintroduced as a race. Write and every reader move through ONE shared record/read function pair, mirroring `record_shell_launch`/`read_shell_launch`. FAIL-TOWARD-ALIVE IS THE PARSE ARM TOO: an unparseable record reads None and REFUSES the kill while LEAVING the record, because kill-nothing-and-retire-the-pid-file-anyway orphans a live waker while presenting success -- worse than the defect being fixed. UNPROVEN REFUSES: the destructive arm treats unknown as do-not-fire (consequence asymmetry -- a mis-fire force-kills a stranger's tree, a missed kill leaves our own binary running and observable), which FALSIFIES the shipped unconditional promise that a link-break's force-close always kills and \\\"the binary never survives\\\", so `close_shell`'s step 3, the REQ-SHELL-2 language, the CONTEXT lifecycle line and KNOWN-HAZARDS 7.58 are amended together with the code rather than one comment patched. THE REFUSAL IS LOUD: every declined kill names the reason and the pid on the channel the close path already speaks, and the bounded confirm loop reports a binary that outlived it -- a quiet wrong state is the un-RCA-able one, and the harm-asymmetry argument has to hold in the log and not only in principle. THIS NARROWS THE MIS-FIRE, IT DOES NOT ELIMINATE IT, AND THE TEXT SAYS SO: on Linux `process_started_at` reads /proc/<pid>/stat field 22, which counts CLK_TCK=100 jiffies, so two processes whose starts fall in the SAME 10ms tick carry an identical stamp and the pair cannot separate them. The window closes from ANY recycled pid to A PID RECYCLED INTO THE SAME 10ms TICK AS THE RECORDED START -- which requires our process to die AND the OS to hand its number to a new process inside one tick, a precondition that is its own mitigation. Windows is unaffected (FILETIME, far finer resolution). Measured by hertz on kitsubito; recorded verbatim so nobody re-derives it. THE ASYMMETRY IS WHY THIS IS THE KILL PATH'S SENTENCE TO WRITE: the same predicate with the same imprecision is SAFE on the derivation side and UNSAFE here -- Held means 'stays stale' for a derived read and 'fire the kill' for a destructive one, so only the kill side carries the residual harm and only the kill side has to declare it. Image-path corroboration (which would unify this rule with the rig-side technique in KNOWN-HAZARDS 7.58) is filed past as releases#120, deliberately not taken in a closing milestone. MIGRATION WINDOW, NAMED NOT SILENT: pre-W2 shell records and pre-fix waker records carry no stamp, read Held on existence alone, and keep today's bare-pid kill until their next launch writes a pair. DOWNGRADE DIRECTION, NAMED: an OLD binary reading the NEW two-line `waker.pid` parse-fails to None, which reads as no-pid and refuses the kill -- missed-kill, not mis-fire, the safe polarity. Gate: impl -- the pair gate in both chokepoints, the shared waker record/read pair with the two-line format, every waker.pid reader moved onto it, the loud refusal arms, and the confirm-loop survivor report; unit -- a recycled pid (live, birth mismatch) is NOT killed where the shipped code kills it, a genuine own-process pair (Held) IS still killed so the gate is not vacuous, an absent stamp keeps the pre-stamp kill, Unproven refuses, an unparseable waker record refuses AND leaves the record in place (asserted together, since retire-anyway passes a kill-count assertion alone), and the refusal is observable rather than silent; int -- hertz's probe inverted: a live stranger parked beside a foreign stamp SURVIVES `kill_shell_at` while `shell_pid_provably_dead` still calls the pair a corpse (the control), with the victim checked through `try_wait` on the held handle rather than a pid-existence probe, which reads alive for an already-killed process while the handle is open.\"\n\n 4166|\n 4167|[[requirements]]\n 4168|id = \"REQ-HAZARD-RESTART-STRANDS-PERSISTENT-SHELLS\"\n-4169|title = \"A NODE RESTART MUST NOT PERMANENTLY STRAND EVERY `persistent` SHELL, AND THE EXISTING CASCADE TEST CANNOT SEE THAT IT DOES. Distinct from REQ-HAZARD-SHELL-STALE-ONLINE, which governs a force-kill DURING operation: this is a different trigger with a different safe remedy, and conflating them is how the restart class stays invisible. THE COVERAGE GAP IS THE HAZARD'S OWN SUBJECT, and it must be named here so no future reader mistakes the cascade test for coverage of this class: `rest_edges_cascade_shells_with_divergence` (spt-daemon resting.rs) is the cascade's only coverage and it walks the graceful path ONLY -- it SUSPENDS FIRST, and the suspend edge WRITES the offline record, so by the time the wake edge fires the instance is already in exactly the state the to_active arm requires. The restart shape -- record left online over a corpse, no rest edge ever -- is UNREACHABLE FROM THAT TEST BY CONSTRUCTION. The test is not weak; its SETUP SUPPRESSES THE FAILING ARM, so a reader asking whether the cascade is covered gets a true answer to the wrong question. This is the third suppressed-arm instance found in one week, and the pattern is the same each time: a fixture that establishes the precondition the code under test is supposed to establish. 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 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 a clean-looking context render must never be taken as proof the class did not occur; the correct falsifier is the on-disk record. Gate: impl -- the restart shape reaches a restoration path at all (leg b) and the record stops lying (leg a); unit -- the RESTART shape specifically, constructed WITHOUT a suspend edge: an instance whose record says online over a corpse that predates boot, with an online owner, is restored -- the row `rest_edges_cascade_shells_with_divergence` cannot express, asserted on a fixture that never calls the suspend path, since a fixture that suspends first re-creates the suppressed arm and proves nothing about this class.\"\n+4179|title = \"A daemon-only or machine restart must not strand persistent shells.

Two legs, and each is worthless alone. **(a) The record stops lying:** the daemon-side reconciler heals a recorded `online` that 2.6's derivation contradicts, writing `offline` — every cycle, **guarded on an actual change** (a heal that rewrote each tick would be a stream of identical writes and would destroy the record's mtime as a signal). **(b) The restart shape reaches a restoration path:** a once-per-daemon-generation boot sweep — and, for an owner that comes online after that sweep has run, an **owner offline→online edge** in the reconcile loop running the identical body (releases#228) — relaunches an instance when **all four** hold — the adapter section declares `persistent`; the **owner endpoint is online** (an offline owner is owed nothing — that is the line between healing a record and resurrecting a shell nobody is there to drive); the instance is down **in fact** (the derived read, made trustworthy across a pid reuse by 2.6's birth stamp); and its recorded launch **predates the boot instant**. No stamp ⇒ **not restored** (the sweep cannot prove it predates boot); no boot oracle on the platform ⇒ nothing restored at all. The boot instant is derived (Linux `btime`; Windows now − `GetTickCount64`), so a named slack constant absorbs derivation jitter and keeps a process launched moments after boot from reading as a corpse from the previous one. **The once-ness of the sweep is scheduling, not safety** (ruled releases#228): the predates-boot discriminant is what forbids relaunching a force-killed shell, and it is monotone within a machine boot — every launch restamps, a kill never does — so a second trigger evaluating the same conjuncts can only refuse more. The second trigger is an **edge**, not the level “owner is online”, which is what bounds a failing launch to one attempt per owner-online event instead of one per reconcile tick.\n- **Regression shape (the row the suppressed fixture cannot express):** construct the restart shape **without a suspend edge** — an instance whose record says `online` over a corpse that predates boot, with an online owner — and assert it is restored.

Lifecycle\n\n### 3.1 Ephemeral perch cleanup on every `ring` exit path\n- **Failure:** `ring` creates an ephemeral perch; early-exit paths (no-perch, empty-msg, timeout) skip cleanup → stale dirs accumulate.\n- **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- **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- **Sister cite:** `src/owl/ring.rs:58-294`.\n\n### 3.2 Stale signoff sentinel must not kill a fresh start\n- **Failure:** a leftover `.claude/<id>-signoff.md` from a prior session is read by a fresh listener as a live signoff → immediate teardown.\n- **Invariant:** on every listener/daemon spawn, sweep stale signoff sentinels; signoff files are write-once per generation.\n- **spt-core mapping:** same sweep on daemon (re)start per hosted instance.\n- **Sister cite:** CHANGELOG v1.11.20; `src/owl/cleanup.rs:97`.\n\n### 3.3 Orphan teardown fires echo-commune BEFORE INIT_SIGNOFF\n- **Failure:** teardown delivers INIT_SIGNOFF without first saving the final context delta → Psyche signoff lacks the context-save summary.\n- **Invariant:** on orphan path, synchronously run the echo-commune (final delta) before composing INIT_SIGNOFF; skip only if the session_id is missing.\n- **spt-core mapping:** the daemon runs psyche/pulse loops in-process; ordering invariant identical.\n- **Sister cite:** `src/live/wrapper/orphan.rs:175-199`; tests A-H:333-565.\n\n### 3.4 A `ring` never adopts — so never deletes — a perch it did not create\n- **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, `info.json`, `spool.db` and the directory. Silent CLI-side fs ops, no daemon log, no console trace (field 2026-07-27 — emphasys lost a live endpoint and its spool to one timed-out ring).\n- **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 the ringer's output**, leaving no trace on either side once the dir is removed. Across a multi-machine subnet that is one agent reading another's mail. Bounded honestly for the record: in the field instance theft did **not** fire — emphasys's 66-second window returned `TIMEOUT` with zero `Replied{…}` — it was available and did not happen.\n- **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- **Marker-down is not an edge case:** on hosted OMP endpoints the extension owns the listener and publishes busy/idle through `api state`, so marker-down is the **normal steady state during work** — marker-first misjudges healthy endpoints routinely.\n- **Invariant:** probe the perch **directory**, not the marker. A dir carrying a **record or a spool** is OCCUPIED — refuse to adopt it. Ambiguity resolves toward refusal, always: an **unreadable** record (corrupt/truncated `info.json`) or an unreadable dir counts as occupied, never as residue, because deletion is irreversible while refusal is recoverable. A pre-existing **empty** dir is refused too — it is not provably ring's own residue (a bringup mid-create owns an empty perch dir for a window, and deleting it is the same race in a different hat). Refusal never blocks and is never silent: the message is delivered, the call declines to block-wait (the reply lands on the caller's own listener), and the caller gets a **distinct** loud report — `RING_PERCH_EXISTS` (record/spool) or `RING_STALE_DIR` (empty; names the path and the manual remedy). Loudness — not a self-heal — is what keeps a permanent refusal from being a silent one. Structural, not advisory: the leaf dir is created with `create_dir` (fails `AlreadyExists`), so a perch appearing between probe and create still cannot be adopted, and the refusal path never calls cleanup.\n- **spt-core mapping:** `spt_msg::ring::{probe_perch, setup_ephemeral, ring}`; `RingOutcome::{PerchExists, StaleDir}` rendered by `cmd_ring`.\n- **Source:** spt-core field incident 2026-07-27 (emphasys endpoint + spool loss); ruled by doyle, with emphasys's mid-create-race amendment revoking the empty-dir self-heal.\n- **Amendment — the perch GC inherits this reasoning EXTENDED, never carved out (doyle, 2026-08-04, releases#109).** A second consumer now deletes perch directories: `spt endpoint gc` (3.5, `REQ-PERCH-GC-RESIDUE-PREDICATE`). Its authority is something `ring` never had — a **positive** statement that the directory carries **no endpoint record at all**, from the store that answers endpoint existence on a node (the owlery tree itself; the perch dir plus its parseable `info.json` IS the endpoint record). That authority does **not** outrank this section's occupancy rules, and the ruling says why: undeliverable-by-construction settles *deliverability*, not *value*, so a recordless dir carrying a **spool** is still refused — that spool is the only surviving copy of whatever was queued, and deleting mail is not a GC's call at any confidence level. A pre-existing **empty** dir is still refused for the reason emphasys's amendment gave: the mid-create window exists for the GC identically, and no still-positive discriminator for \"not mid-create\" exists for an empty dir (there is no create-intent marker, and mtime is out by the GC's own predicate). What the GC *may* delete is therefore strictly narrower than what it may *call* residue, and both refusals are kept honest exactly as this section requires — **loudly**, per path, under distinct tokens (`RESIDUE-WITH-SPOOL` / `RESIDUE-EMPTY`) with the manual remedy named. A refusal also **shields the whole subtree under it** — a nested child that would qualify on its own is reported `SHIELDED-BY-REFUSED-PARENT` and left alone, because refusing a directory has to mean not modifying its CONTENTS either (carving a child out destroys part of what the refusal report asked the operator to look at, and can move the parent's own verdict on the next pass). The one discriminator the GC has and `ring` does not is the **held `.info.lock`**: a NON-empty recordless dir whose per-perch write sentinel is held right now is a bringup mid-create, provably, and is refused (`OCCUPIED-WRITE-IN-FLIGHT`). An empty dir gets no such signal, which is why its refusal stays unconditional.\n<!-- [doc->REQ-HAZARD-RING-PERCH-ADOPTION] -->\n\n### 3.5 `is_perch_alive` is INVERTED on perch residue — a GC must never key on it\n<!-- [doc->REQ-HAZARD-PERCH-GC-LIVENESS-INVERSION] -->\n<!-- [doc->REQ-PERCH-GC-RESIDUE-PREDICATE] -->\n- **Failure:** the obvious way to write a perch garbage collector is \"reap what is not alive\" — `!spt_store::liveness::is_perch_alive(dir)`. On the population a GC actually walks, that predicate is **backwards**. `is_perch_alive` returns **true** for a directory with no `info.json` (`RawRead::Absent ⇒ true`, interim parity — an absent record means a wrapper-owned listener between polls), and **false** for a daemon-hosted endpoint whose `status` is `offline`. Measured on HFENDULEAM 2026-08-04 across 38 top-level perch dirs: **all 24 recordless residue directories read ALIVE, and all 6 offline REAL endpoints read DEAD.** A sweep keyed on `!is_perch_alive` would have spared every stray probe directory and deleted six resting agents' records — it does not under-perform, it authorizes **exactly the inverse set**.\n- **Why it is a hazard and not a bug in the resolver:** `is_perch_alive` is correct for its own job. Fail-toward-alive is the safe direction for DELIVERY (2.5) — the cost of a false \"alive\" is one message taking the spool path. It is the wrong direction for DELETION, where a false \"not alive\" is irreversible. The inversion is what happens when a predicate is reused across a polarity boundary it was never sized for.\n- **Invariant:** perch garbage collection classifies on record **presence** only (3.5's predicate: no `info.json` present on any read attempt ⇒ residue; NotFound kept distinct from every other I/O error, because absent is the only answer that authorizes deletion) and **never calls a liveness resolver** — not `is_perch_alive`, not `is_registry_entry_alive`, not a pid probe. The registry is likewise never asked: `clean_stale_entries` deletes dead-pid rows and `unregister_address` fires on an ordinary stop, so registry-absence is the normal steady state of every offline endpoint (4.3). The unit pinning this asserts **both** arms with the shipped resolver as the witness: residue reads alive and is reaped anyway; an offline endpoint reads dead and is kept anyway.\n- **spt-core mapping:** `spt_store::perchgc::{sweep, PerchClass}`; `spt endpoint gc` renders it. The refusal/report contract is `REQ-PERCH-GC-REFUSAL-REPORT`; the occupancy rules it inherits are 3.4.\n- **Source:** measured by todlando on HFENDULEAM 2026-08-04 while answering doyle's step-1 predicate question on releases#109; ruled into the lane by doyle the same day.\n\n---\n\n## 4. Wire / transport\n\n### 4.1 Envelope HTML-entity codec ordering — `&amp;` decoded LAST\n- **Failure:** decoding `&amp;`-entity before the others double-decodes nested entities (`&amp;amp;lt;` → wrong result).\n- **Invariant:** ENCODE order amp→first … `<br>`→last; DECODE order `<br>`→first … amp→**last** (`&lt;`,`&gt;`,`&quot;`, then `&amp;`). One sole decode site (at the LLM/stdin boundary); the parser never decodes.\n- **spt-core mapping:** `spt-proto` owns the envelope grammar (public SDK, semver + wire-version). This codec contract is a copy-verbatim commodity item (ADR-0001) and a public-API conformance test.\n- **Sister cite:** `src/owl/poll.rs:1-73`; `src/common/envelope.rs`.\n- **CR-linesafety `[REQ-HAZARD-ENVELOPE-CR-LINESAFE]`:** the EVENT is LINE-FRAMED, so the codec must neutralize raw `\\r` too — `event_body_escape` folds CRLF/lone-CR to `\\n` (→`<br>`) **before** framing. **Failure (field, 2026-06-08):** a cross-node `spt send` from Windows (`echo` → CRLF) carried a raw `\\r` into the single-line envelope; the receiver terminal did a CR→column-0 overwrite (`</EVENT>` clobbered `<EVENT t`). `\\r` was never line-representable here, so normalizing it is robustness, not an ADR-0001 wire divergence (decoder + amp-last untouched). Belt-and-suspenders: `spt send`/`ring` trim stdin like `notify`.\n\n### 4.2 Two-slice envelope parser is panic-free and tolerant\n- **Failure:** malformed envelope (unclosed/misordered/nested tags) panics or drops output.\n- **Invariant:** tags case-sensitive, all optional; no tags → whole body to live slot; unclosed → None for that tag; out-of-order → both still extracted; nested unknown tags preserved verbatim; zero `unwrap` on parsed text.\n- **spt-core mapping:** `spt-proto` parser; property-test the robustness rules.\n- **Sister cite:** `src/common/envelope.rs:64-92`; tests 99-207.\n\n### 4.3 Registry stale-entry cleanup precedes lookup\n- **Failure:** sender resolves a dead process's stale TCP port → delivery to wrong/dead listener.\n- **Invariant:** clean stale entries (dead PID) before/at lookup; spool fallback is the safe path on TCP miss.\n- **spt-core mapping:** now spans the **subnet registry** (ADR-0003) — eventually-consistent across nodes. Cross-node staleness is expected; resolution policy (local → most-recent → `id@node`) must degrade to spool/relay fallback on stale hits, and never hard-fail on a stale remote entry.\n- **Sister cite:** `src/common/registry.rs:62-78`; `src/owl/send.rs`.\n\n### 4.4 Deferred rows survive poll drain\n- **Failure:** poll `drain_all` flushes a deferred (spool-only) message meant for a hook consumer → message lost.\n- **Invariant:** deferred rows are never flushed by the event-stream drain; only `drain_non_deferred_*` / `peek_all` touch them.\n- **Sister cite:** CHANGELOG v1.11.20; `src/common/spool.rs`. (See also 1.4.)\n\n### 4.5 Inbox legacy compat must not double-deliver\n- **Failure:** message surfaced via both spool (durable) and legacy inbox files → duplicate or racing delivery.\n- **Invariant:** spool is the sole read path at poll time; inbox is write-for-compat only and never read.\n- **spt-core mapping:** clean-room — likely drop the legacy inbox entirely. If kept for any compat, preserve \"never read at drain time.\"\n- **Sister cite:** `src/common/inbox.rs`.\n\n### 4.6 Addressable-id charset reserves the address delimiters\n<!-- [doc->REQ-HAZARD-ID-CHARSET] -->\n- **Failure:** a bare endpoint id that contains `:` or `@` (or a path separator / whitespace / control char) makes the canonical qualified address `[subnet:]id[@node]` (ADR-0006 / REQ-INST-10) ambiguous to parse, and lets a name smuggle into a perch directory path. Once permissive ids exist in the wild, tightening later needs a migration.\n- **Invariant:** every addressable id/name is validated to `[A-Za-z0-9_-]` + Hiragana/Katakana/CJK only, length `1..=64`, **at every creation seam** (`ready` start, `api bind`, `api listen`, `api worker-start`). `:` and `@` are permanently reserved as address delimiters; reads of existing perches are never re-validated. Enforce now (pre-M3/M4) so no permissive id-data accumulates.\n- **spt-core mapping:** `spt_proto::id::validate_endpoint_id`; called at the four creation seams. The existing Psyche (`<parent>-psyche`) / Worker (`<parent>-w<N>`) suffix scheme uses only `-` + alphanumerics, so composite ids validate.\n\n### 4.7 Concurrent SQLite openers must not fail with \"database is locked\"\n<!-- [doc->REQ-HAZARD-REGISTRY-CONCURRENT] -->\n- **Failure:** two endpoints on one machine open the same SQLite store at once (e.g. two `ReadyAgent::start` calls registering simultaneously) and one fails outright with `SQLITE_BUSY` / \"database is locked\" → spurious registration/spool failure. Surfaced as a parallel-test flake in `two_agents_exchange_message_tcp_and_spool`, but the bug is real concurrency, not test-only.\n- **Invariant:** `busy_timeout` is set **before** any lock-taking statement on every connection. Switching `journal_mode=WAL` takes a brief exclusive lock; with the default 0ms timeout it fails immediately under contention, so the pragma order is load-bearing: `Connection::open` → `busy_timeout` → `journal_mode=WAL` → `CREATE TABLE …`. WAL alone is insufficient (concurrent *writers* still serialize; they must *wait*, not error).\n- **spt-core mapping:** `spt_store::registry::open_registry` + `spt_store::spool::open_spool_at`; both set `busy_timeout=5000` first. Any future SQLite store (history Path B, instance registry) must follow the same ordering.\n\n### 4.8 Registry merge ordered by epoch, never wall-clock (red-team #8)\n<!-- [doc->REQ-HAZARD-REGISTRY-EPOCH-LEASE] -->\n- **Failure:** the per-subnet registry replicates `endpoint_id → [instances]` eventually-consistently across nodes. Under a partition or clock skew, a lagging node re-announces a stale `Active` for an endpoint that has actually gone `Offline`. If the merge ordered updates by wall-clock (or \"last write wins\"), the stale `Active` overwrites the newer `Offline` and resolution routes a message to a dead/wrong instance.\n- **Invariant:** the merge precedence key is a **per-node monotonic epoch counter** (`spt_store::epoch::EpochSource`, persisted, strictly increasing, NEVER wall-clock), compared version-vector style per `(endpoint_id, node)`: an incoming update wins **iff its epoch is strictly greater** than the stored one for that node; equal or lower is dropped as stale. So a newer `Offline` (higher epoch) can never be clobbered by a lagging `Active` (lower epoch), and an idempotent equal-epoch replay is a no-op. Wall-clock is at most a human tiebreaker hint inside a flagged conflict, never the ordering authority. The same epoch source unifies with the D6 sync-precedence concurrent-write detection (#7).\n- **spt-core mapping:** `spt_net::net::registry::SubnetRegistry::merge_instance` (the lease) + `spt_store::epoch::EpochSource` (the counter). Cross-node replication of the merge wires at D4; the merge seam is identical for local and wire-delivered updates. Chaos/two-host verification = D9.\n\n### 4.9 SQLite stores must create their parent dir — SQLite won't\n<!-- [doc->REQ-HAZARD-REGISTRY-DIR-CREATE] -->\n[…140ln elided…]\n\n<!-- [doc->REQ-HAZARD-TREE-CWD-PIN] -->\n### 5.18 A surviving test descendant cwd-pins the tree it ran in — the `.worktrees` skeleton that will not delete  `[REQ-HAZARD-TREE-CWD-PIN]`\n- **Failure:** a directory that is some live process's **current directory** cannot be renamed or deleted on Windows, while files *inside* it stay writable. That asymmetry is why the symptom never reads as a file lock: `git worktree remove` fails naming the **directory**, `openfiles` shows nothing, and the tree looks idle. cargo runs each test binary with cwd = the **package root**, so every child a test spawns inherits `<worktree>/crates/<pkg>` as its own cwd — and any child (or **grandchild**) that outlives the test pins that path forever. Result: a silent `.worktrees` skeleton accumulator, each one costing the next agent an afternoon.\n- **Mechanism — the common case is a surviving descendant, and it is not the `CREATE_NO_WINDOW` conhost.** releases#110 filed the holder as an *orphaned `conhost.exe` holding the crate root*; measurement on HFENDULEAM 2026-08-02 **refutes** that for the population the rigs mint. `CREATE_NO_WINDOW` does produce exactly **one conhost per console child** (counted by `ParentProcessId`), but that conhost's cwd is **not** inherited: it is launched with a system cwd. Census: **43 readable, all of them `C:\\WINDOWS\\` or `C:\\WINDOWS\\system32\\`, zero under any worktree** (4 unopenable, stated). Held directly: spawning a child with cwd = the package root and then force-killing it leaves the orphan conhost still reading `C:\\WINDOWS\\`. Positive control on a scratch dir — write-inside **OK**, delete **BLOCKED**, kill the **conhost** → still BLOCKED, kill the actual holder → **deletes first try**. The holder in that control turned out to be an orphaned **grandchild** (`PING.exe`, cwd inherited through `cmd`) that survived its parent's kill. **That conhost is a byproduct, never the pin; killing it is not the cure and \"no conhosts\" is not the all-clear.**\n- **Amendment 2026-08-02 — the exception, field-refuted before it shipped: a `--headless` ConPTY conhost DOES inherit its creator's cwd, and pins it alone.** The entry previously generalized the census above into \"a conhost's cwd is never inherited\". That is true of the `CREATE_NO_WINDOW` population and false of the ConPTY one, which no rig mints but every terminal-hosting path does.\n  - **Field specimen (BAROMETER W4 teardown):** `pid 46556 conhost.exe --headless --width 80 --height 24 --signal 0x214 --server 0x20c`, born during the build, parent dead, PEB cwd `…\\.worktrees\\barometer-w4\\crates\\spt\\` — the **sole** holder. Killing it deleted the tree that had refused to delete.\n  - **Reproduced deliberately, both launch paths.** Minted through `CreatePseudoConsole` from a process whose cwd was a scratch dir: the new `--headless` conhost's PEB reads **that dir**, and with it alive — write-inside **OK**, delete **BLOCKED**, then **DELETED** after `ClosePseudoConsole`, nothing else changed. Launched as `conhost.exe --headless` directly with a working directory: same inheritance. The first covers the path the wild specimen took; the second shows the binary takes its launcher's cwd in that mode regardless.\n  - **The pty-teardown alternative is excluded causally, not by absence.** \"Zero children\" clears nothing here — a ConPTY client is a child of whoever called `CreatePseudoConsole`, never of the conhost — so killing the conhost could in principle have taken a living client with it. Kill-**order** rig, client deliberately `cd`'d elsewhere so it cannot be the holder: both alive → **BLOCKED**; kill the **client** only → still **BLOCKED**; kill the **conhost** → **deleted**.\n  - **A census of live `--headless` conhosts cannot settle this in either direction.** All 8 alive that day read `C:\\WINDOWS\\system32\\` — and their single creator's cwd *is* `C:\\WINDOWS\\system32\\`, so the value inheritance predicts equals the value OS-assignment predicts, on rows uniform in the asserted property. It reads as confirmation of the old claim and carries no information; the deliberate launch is what discriminates.\n  - **Elevation is not the discriminator, and neither reader needs it.** Both readers open with `PROCESS_QUERY_INFORMATION | PROCESS_VM_READ` only and, **unelevated**, read ~46–49 of the ~50 conhosts alive. A first pass that reported *no* conhost readable was a parsing fault in the caller, not an access denial — worth stating because \"not readable\" and \"read as `C:\\WINDOWS\\`\" are the same blank row to a careless reader.\n  - **Scoped conclusion:** a `CREATE_NO_WINDOW` conhost is never the pin and killing it is never the cure; a `--headless` ConPTY conhost **can be the sole pin**, and there killing it **is** the cure. Neither sentence licenses the other.\n- **Triage step — the finder answers WHO pins, never whether it is SAFE TO KILL.** These are different questions and the blocked-delete error is **identical** for both, which is exactly what makes the step worth writing down. Read the holder's identity *before* acting: an **orphaned descendant** (parent dead, no window, no client) → kill it; a **LIVE process — above all an agent's own shell** → `cd` out, never kill. **When the holder is a `conhost.exe`, its COMMAND LINE is the discriminator** — a bare `conhost.exe 0x…` is the `CREATE_NO_WINDOW` byproduct and is never the pin (look behind it for the descendant), while `conhost.exe --headless --width … --server …` is a ConPTY host that can be the pin itself and dies to a kill. Do not read its **child count** as evidence either way: a ConPTY's client is a child of the pseudoconsole's creator, not of the conhost, so \"zero children\" says nothing about what is alive behind it. Live confirmation 2026-08-02: after one worktree cleared, an identical error on a second traced to a working agent's **own pwsh tool shell**, and behind it that agent's **Bash tool** cwd in the same tree (the two hold *separate* cwds, so clearing one leaves the other). Pattern-matching the kill recipe there would have cost a working agent their session. The pin also follows whatever crate the test ran under, not a fixed package.\n- **spt-core mapping:** `.github/ci/find-cwd-holders.ps1` — read-only (`PROCESS_QUERY_INFORMATION | PROCESS_VM_READ`, `NtQueryInformationProcess` → PEB → `RTL_USER_PROCESS_PARAMETERS.CurrentDirectory`), no process opened for write or killed; `-Match <substring>` filters by cwd. It reports its **denominator** (readable vs not-openable) because \"0 rows\" from a filter and \"0 rows\" because nothing could be opened are the same output and very different facts — an empty result means \"no pin I could see\", never \"no pin\". `handle.exe` is not on the box by default and does not distinguish a cwd pin from an open handle; `openfiles` cannot see this at all without the reboot-time maintain-objects-list flag. The **prevention** side is teardown completeness — a rig that reaps its own descendants leaves nothing to pin — which is the `REQ-TEST-RIG-DAEMON-TEARDOWN-PROVEN` (#99) class extended to grandchildren, measured by surviving-process count on both arms rather than asserted.\n- **Do NOT \"fix\" this with the spawn flag.** Flipping the rigs' `CommandNoWindowExt::no_window()` (`crates/spt/tests/common/mod.rs`) from `CREATE_NO_WINDOW` to `DETACHED_PROCESS` removes the conhost (measured: 1 → 0) but does **not** remove the pin (that conhost is never the holder — the `--headless` ConPTY exception above is a host no rig mints through this helper), and it breaks rigs outright per the 5.17 amendment: `job_escape_e2e::conhost_children_of` shells out to **powershell** through that very helper and falls back to `unwrap_or(0)`, so a detached spawn would make `wmi_daemon_run_has_no_conhost_window` — the guard for `REQ-HAZARD-WMI-DAEMON-WINDOW` — assert \"no conhost\" **vacuously green**, a gate whose failure signature is identical to the fault it guards. Nor can the helper simply hand children a neutral cwd: `bind_cwd_project_e2e` and `resume_template_e2e` deliberately assert on the **inherited** cwd, which is the behavior under test.\n- **Source:** hertz, releases#110 — filed diagnosis post-v0.51.0 (2026-08-01); mechanism re-measured and the conhost attribution **refuted** 2026-08-02 (per-parent conhost counts, box-wide conhost cwd census, orphan-grandchild positive control). doyle's live correction the same day supplied the live-shell half of the triage step. **The `--headless` exception is field evidence from todlando** (BAROMETER W4 teardown specimen, the direct-launch inheritance test, and the kill-order rig that excluded pty teardown), reproduced through the `CreatePseudoConsole` path with a delete-blocked/deleted control by hertz, and ruled an in-milestone amend by doyle the same day — the entry was refuted **before** it shipped in a golden run.\n\n<!-- [doc->REQ-TEST-ENV-ONE-LOCK] -->\n### 5.19 Two mutexes over one process-global env var guard nothing between them  `[REQ-TEST-ENV-ONE-LOCK]`\n- **Failure:** two test-helper crates each declare their own `static ENV_LOCK` over the SAME process-global variable (`SPT_HOME`). Each serializes its own callers **flawlessly** — which is exactly what makes the arrangement read as correct — and neither serializes helper A against helper B. Whichever writes last wins. Because `spt_store::perch::spt_home()` is **not memoized** (it re-reads the env on every call), a test writes its fixture into home A and reads it back from home B: the store is absent, an empty access baseline is minted over it, and the assertion fails on a policy that was never loaded. Field shape (releases#111): `cargo test -p spt-daemon --lib dispatch::` lost **1–3 of 26 nondeterministically**, `an_unadmitted_asker_is_refused_at_this_nodes_own_seam` reading `Some(offline)` where the rules should have answered `None`.\n- **Invariant (rig discipline, like 5.17):** one variable, one lock, **per binary**. A crate may keep its own ergonomic wrapper (`with_home`, `isolated_home`, a `TestHome` guard) but must **never** keep its own mutex over a variable another helper in the same binary also writes. `spt_test_support::env_lock()` is THE lease; crate-local helpers return that guard. It is **not reentrant** — a `TestHome` holds it for its whole lifetime, so one is never constructed inside a body already holding the lease.\n- **Why it hides, and where it does not:** invisible under **nextest** (per-test processes) and invisible when a loser is run **alone** (no concurrent holder), so CI's nextest unit lane is structurally blind to it — the cost falls entirely on whoever hand-runs the module during a gate. This is the same \"invisible-by-construction\" property as 5.17, and the reason it is numbered here rather than left to the requirement.\n- **The diagnostic that shortcuts it:** the tell is a **path shape the suspected helper could not have produced**. #111's panic printed `<tmp>\\home\\identity\\trust\\access.json` — a `home` SUBDIR, which `with_home` never makes (it points `SPT_HOME` at the tempdir *root*). That single mismatch named the real aggressor (`spt_test_support::TestHome`) faster than reading either helper. Corollary for the filed-mechanism trap: `with_home` holds its mutex across its **entire body**, so \"a sibling `with_home` test retargets the home mid-test\" — the filed story — was impossible; read a helper's lock SCOPE before accepting a race that names it.\n- **spt-core mapping:** `spt_test_support::env_lock` (the one lease) consumed by `spt_daemon::test_home::{env_lock, with_home}` and `spt::testutil::isolated_home`. Guard: `test_home::tests::with_home_and_testhome_serialize_on_the_same_lease` — a `with_home` body holds the lease while a second thread attempts a `TestHome`, asserting the thread cannot enter and `SPT_HOME` cannot move, **then** that it does proceed once released (so a shared lock is proven to be a lock, not a deadlock). Reds on the two-lock code, greens on one. **Sweep discipline recorded because one instance of a class is not the class:** the population is every crate declaring an `SPT_HOME` helper INTERSECTED with the binaries that also reach `spt_test_support`; running it found a second live, unreported instance (`crates/spt`'s `testutil::LOCK` beside `cli.rs`'s direct `TestHome`). `spt-live` and `spt-store` depend on `spt-test-support` not at all, and `spt-msg` declares no helper of its own.\n- **Source:** releases#111 (filed by doyle from hertz's gate observation, 2026-08-02); filed mechanism refuted and the real root measured the same day — hertz. Cousin class, same date: two builds writing one binary path with nothing guarding between them, which is why the gate recipe now identity-checks the exe hash (doyle, W2 gate).\n\n<!-- [doc->REQ-POOL-FOREIGN-TREE-REFUSED] -->\n### 5.20 Two source trees sharing one cargo target directory fabricate reds that belong to neither  `[REQ-POOL-FOREIGN-TREE-REFUSED]`\n- **Failure:** a gate lane and a builder lane both built through `.worktrees/gate-target`. The gate compiled against the builder's mid-seam, half-written artifacts and reported an `E0308` in `psyche_event_turn_e2e` that **vanished on re-run** — a red belonging to neither tree, in a lane whose entire job is to be believed. The reverse is worse and silent: the builder's green was equally untrustworthy and nothing said so. Reproduced small (releases#103): two packages of the same name and version, built from two DIFFERENT paths into one pool, resolve to **one** build-script output dir and overwrite each other.\n- **Why it hides:** the sharing is invisible at the point of use. A junction shows as an ordinary `target/` and nothing in cargo's output names the real directory; `CARGO_TARGET_DIR` is quieter still — it does not even leave a directory entry to notice afterwards. Both reach the same hazard, which is why the rule is about the **relationship** (this tree writing into a target owned by another) and never about a path: the incident that motivated the filing pointed `CARGO_TARGET_DIR` at the *primary checkout*, which no rule about `.worktrees/` would have covered.\n- **The harm is INTERLEAVING, not simultaneity.** Cargo holds an exclusive `.cargo-lock` for a build's duration, so two builds are never literally concurrent — the second blocks. What bit was one lane's artifacts being invalidated by another **between that lane's own steps**. A lease keyed on a `cargo` process therefore guards nothing: it is stale seconds after every claim, so every crossing reads as a takeover and the refusal can never fire. That shape was designed, measured, and refused.\n- **Invariant:** a pool belongs to one source tree. `crates/spt-store/build.rs` enforces it and refuses with `SPT_POOL_FOREIGN`, naming the pool, the owning tree, the lane, the holder pid and the way out. Sequential sharing is correct and cheap — a provably-gone lane is a **loud takeover**, never a refusal, because refusing it would demand a pool per lane (30+ worktrees at a measured 7-15 GB each). Staleness is proven from the **process table plus the birth stamp**; UNKNOWN is not stale and proceeds with a warning. An ownerless pool imprints its first builder, so a developer's own fresh `target/` is never refused. `SPT_POOL_UNCHECKED=1` overrides and says so on every build it allows.\n<!-- [doc->REQ-POOL-LANE-IDENTITY] -->\n- **A DEAD HOLDER IS NOT A FINISHED LANE `[REQ-POOL-LANE-IDENTITY]`.** The first shape of this guard answered \"has that lane finished?\" from the holder process alone. Measured on this box afterwards: **3 of 3 live pool claims had a dead holder, and one of those three lanes was live.** A holder is an agent session or a rig shell — cleared, re-forked, re-parented as a matter of routine — so its death says nothing about the lane, and reading it as \"finished\" hands the pool to a second tree **mid-lane**, i.e. reaches this very hazard *through* the guard. So the claim records the lane's **git identity** (its branch and the base sha that branch carried at claim time) and the finished question is answered by **ancestry**: in flight while the lane's tip is not contained in the integration head; settled once it is merged, once the branch is gone, or once the branch no longer carries the claimed base — a branch name re-pointed onto other work is the branch-level twin of a recycled pid. **The base sha is also the repo-identity witness:** ancestry is read in the *arriving* tree, so a branch absent from a *different* repository would otherwise read as a finished lane; an unanchored claim answers UNKNOWN, never \"settled\". (Found by its own test, which read `Settled: branch no longer exists` out of a directory that was not a repository at all.) **Precedence is asymmetric:** a live holder may only ever ADD a refusal, ancestry alone may declare a lane settled, and a stamp written before the identity fields existed keeps its old behaviour and says so in the line it prints. **What this arm covers, stated exactly:** the enforcer is the build script of the tree that ARRIVES, never the claim it reads, so a lane is protected when the arriving tree carries this change — coverage grows as trees turn over and is never retroactive (measured: a rig whose arriving worktree sat at the pre-identity sha took the pool over, which is the old behaviour working correctly in an old tree). A version line in the stamp cannot fix that and is refused: the tree that must refuse is the one that does not read the new field, so the reader is the problem and not the record. **Every refusal's remedy must be a command that RUNS** — `xtask` depends on `spt-store`, so any command building the tool goes through the refused pool; measured from the refusal state, a remedy naming a bare `cargo run … pool-release` failed with the identical refusal that printed it. The rule is enforced over the whole population of refusal arms, because it was learned once on one arm and re-broken by the next arm added.\n- **The guard's own hazard:** the build script must emit **no** `rerun-if` directive. It is re-run because cargo's fingerprint for its unit carries `CARGO_MANIFEST_DIR`, i.e. on exactly the tree ALTERNATION the guard exists to catch. Measured on byte-identical trees, sequence `A B A A B`: no directives → 4 firings; one `rerun-if-changed` → **1**, and the foreign tree never fired it again. `crates/spt-store/tests/pool_guard_canary.rs` reads the shipped build script and reds if a directive appears — a comment would be a prohibition, not a boundary.\n- **Source:** BAROMETER W1/H1 window (doyle + todlando, 2026-08-02); design measured and built by hertz, releases#103.\n\n---\n\n## 6.

Two legs, and each is worthless alone. **(a) The record stops lying:** the daemon-side reconciler heals a recorded `online` that 2.6's derivation contradicts, writing `offline` — every cycle, **guarded on an actual change** (a heal that rewrote each tick would be a stream of identical writes and would destroy the record's mtime as a signal). **(b) The restart shape reaches a restoration path:** a once-per-daemon-generation boot sweep — and, for an owner that comes online after that sweep has run, an **owner offline→online edge** in the reconcile loop running the identical body (releases#228) — relaunches an instance when **all four** hold — the adapter section declares `persistent`; the **owner endpoint is online** (an offline owner is owed nothing — that is the line between healing a record and resurrecting a shell nobody is there to drive); the instance is down **in fact** (the derived read, made trustworthy across a pid reuse by 2.6's birth stamp); and its recorded launch **predates the boot instant**. No stamp ⇒ **not restored** (the sweep cannot prove it predates boot); no boot oracle on the platform ⇒ nothing restored at all. The boot instant is derived (Linux `btime`; Windows now − `GetTickCount64`), so a named slack constant absorbs derivation jitter and keeps a process launched moments after boot from reading as a corpse from the previous one. **The once-ness of the sweep is scheduling, not safety** (ruled releases#228): the predates-boot discriminant is what forbids relaunching a force-killed shell, and it is monotone within a machine boot — every launch restamps, a kill never does — so a second trigger evaluating the same conjuncts can only refuse more.

Lifecycle\r\n\r\n### 3.1 Ephemeral perch cleanup on every `ring` exit path\r\n- **Failure:** `ring` creates an ephemeral perch; early-exit paths (no-perch, empty-msg, timeout) skip cleanup → stale dirs accumulate.\r\n- **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.\r\n- **spt-core mapping:** `ring` semantics carry; the daemon owns ephemeral-perch lifecycle, so a single guaranteed-cleanup (drop guard / RAII) is achievable in-process.\r\n- **Sister cite:** `src/owl/ring.rs:58-294`.\r\n\r\n### 3.2 Stale signoff sentinel must not kill a fresh start\r\n- **Failure:** a leftover `.claude/<id>-signoff.md` from a prior session is read by a fresh listener as a live signoff → immediate teardown.\r\n- **Invariant:** on every listener/daemon spawn, sweep stale signoff sentinels; signoff files are write-once per generation.\r\n- **spt-core mapping:** same sweep on daemon (re)start per hosted instance.\r\n- **Sister cite:** CHANGELOG v1.11.20; `src/owl/cleanup.rs:97`.\r\n\r\n### 3.3 Orphan teardown fires echo-commune BEFORE INIT_SIGNOFF\r\n- **Failure:** teardown delivers INIT_SIGNOFF without first saving the final context delta → Psyche signoff lacks the context-save summary.\r\n- **Invariant:** on orphan path, synchronously run the echo-commune (final delta) before composing INIT_SIGNOFF; skip only if the session_id is missing.\r\n- **spt-core mapping:** the daemon runs psyche/pulse loops in-process; ordering invariant identical.\r\n- **Sister cite:** `src/live/wrapper/orphan.rs:175-199`; tests A-H:333-565.\r\n\r\n### 3.4 A `ring` never adopts — so never deletes — a perch it did not create\r\n- **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, `info.json`, `spool.db` and the directory. Silent CLI-side fs ops, no daemon log, no console trace (field 2026-07-27 — emphasys lost a live endpoint and its spool to one timed-out ring).\r\n- **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 the ringer's output**, leaving no trace on either side once the dir is removed. Across a multi-machine subnet that is one agent reading another's mail. Bounded honestly for the record: in the field instance theft did **not** fire — emphasys's 66-second window returned `TIMEOUT` with zero `Replied{…}` — it was available and did not happen.\r\n- **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.\r\n- **Marker-down is not an edge case:** on hosted OMP endpoints the extension owns the listener and publishes busy/idle through `api state`, so marker-down is the **normal steady state during work** — marker-first misjudges healthy endpoints routinely.\r\n- **Invariant:** probe the perch **directory**, not the marker. A dir carrying a **record or a spool** is OCCUPIED — refuse to adopt it. Ambiguity resolves toward refusal, always: an **unreadable** record (corrupt/truncated `info.json`) or an unreadable dir counts as occupied, never as residue, because deletion is irreversible while refusal is recoverable. A pre-existing **empty** dir is refused too — it is not provably ring's own residue (a bringup mid-create owns an empty perch dir for a window, and deleting it is the same race in a different hat). Refusal never blocks and is never silent: the message is delivered, the call declines to block-wait (the reply lands on the caller's own listener), and the caller gets a **distinct** loud report — `RING_PERCH_EXISTS` (record/spool) or `RING_STALE_DIR` (empty; names the path and the manual remedy). Loudness — not a self-heal — is what keeps a permanent refusal from being a silent one. Structural, not advisory: the leaf dir is created with `create_dir` (fails `AlreadyExists`), so a perch appearing between probe and create still cannot be adopted, and the refusal path never calls cleanup.\r\n- **spt-core mapping:** `spt_msg::ring::{probe_perch, setup_ephemeral, ring}`; `RingOutcome::{PerchExists, StaleDir}` rendered by `cmd_ring`.\r\n- **Source:** spt-core field incident 2026-07-27 (emphasys endpoint + spool loss); ruled by doyle, with emphasys's mid-create-race amendment revoking the empty-dir self-heal.\r\n- **Amendment — the perch GC inherits this reasoning EXTENDED, never carved out (doyle, 2026-08-04, releases#109).** A second consumer now deletes perch directories: `spt endpoint gc` (3.5, `REQ-PERCH-GC-RESIDUE-PREDICATE`). Its authority is something `ring` never had — a **positive** statement that the directory carries **no endpoint record at all**, from the store that answers endpoint existence on a node (the owlery tree itself; the perch dir plus its parseable `info.json` IS the endpoint record). That authority does **not** outrank this section's occupancy rules, and the ruling says why: undeliverable-by-construction settles *deliverability*, not *value*, so a recordless dir carrying a **spool** is still refused — that spool is the only surviving copy of whatever was queued, and deleting mail is not a GC's call at any confidence level. A pre-existing **empty** dir is still refused for the reason emphasys's amendment gave: the mid-create window exists for the GC identically, and no still-positive discriminator for \"not mid-create\" exists for an empty dir (there is no create-intent marker, and mtime is out by the GC's own predicate). What the GC *may* delete is therefore strictly narrower than what it may *call* residue, and both refusals are kept honest exactly as this section requires — **loudly**, per path, under distinct tokens (`RESIDUE-WITH-SPOOL` / `RESIDUE-EMPTY`) with the manual remedy named. A refusal also **shields the whole subtree under it** — a nested child that would qualify on its own is reported `SHIELDED-BY-REFUSED-PARENT` and left alone, because refusing a directory has to mean not modifying its CONTENTS either (carving a child out destroys part of what the refusal report asked the operator to look at, and can move the parent's own verdict on the next pass). The one discriminator the GC has and `ring` does not is the **held `.info.lock`**: a NON-empty recordless dir whose per-perch write sentinel is held right now is a bringup mid-create, provably, and is refused (`OCCUPIED-WRITE-IN-FLIGHT`). An empty dir gets no such signal, which is why its refusal stays unconditional.\r\n<!-- [doc->REQ-HAZARD-RING-PERCH-ADOPTION] -->\r\n\r\n### 3.5 `is_perch_alive` is INVERTED on perch residue — a GC must never key on it\r\n<!-- [doc->REQ-HAZARD-PERCH-GC-LIVENESS-INVERSION] -->\r\n<!-- [doc->REQ-PERCH-GC-RESIDUE-PREDICATE] -->\r\n- **Failure:** the obvious way to write a perch garbage collector is \"reap what is not alive\" — `!spt_store::liveness::is_perch_alive(dir)`. On the population a GC actually walks, that predicate is **backwards**. `is_perch_alive` returns **true** for a directory with no `info.json` (`RawRead::Absent ⇒ true`, interim parity — an absent record means a wrapper-owned listener between polls), and **false** for a daemon-hosted endpoint whose `status` is `offline`. Measured on HFENDULEAM 2026-08-04 across 38 top-level perch dirs: **all 24 recordless residue directories read ALIVE, and all 6 offline REAL endpoints read DEAD.** A sweep keyed on `!is_perch_alive` would have spared every stray probe directory and deleted six resting agents' records — it does not under-perform, it authorizes **exactly the inverse set**.\r\n- **Why it is a hazard and not a bug in the resolver:** `is_perch_alive` is correct for its own job. Fail-toward-alive is the safe direction for DELIVERY (2.5) — the cost of a false \"alive\" is one message taking the spool path. It is the wrong direction for DELETION, where a false \"not alive\" is irreversible. The inversion is what happens when a predicate is reused across a polarity boundary it was never sized for.\r\n- **Invariant:** perch garbage collection classifies on record **presence** only (3.5's predicate: no `info.json` present on any read attempt ⇒ residue; NotFound kept distinct from every other I/O error, because absent is the only answer that authorizes deletion) and **never calls a liveness resolver** — not `is_perch_alive`, not `is_registry_entry_alive`, not a pid probe. The registry is likewise never asked: `clean_stale_entries` deletes dead-pid rows and `unregister_address` fires on an ordinary stop, so registry-absence is the normal steady state of every offline endpoint (4.3). The unit pinning this asserts **both** arms with the shipped resolver as the witness: residue reads alive and is reaped anyway; an offline endpoint reads dead and is kept anyway.\r\n- **spt-core mapping:** `spt_store::perchgc::{sweep, PerchClass}`; `spt endpoint gc` renders it. The refusal/report contract is `REQ-PERCH-GC-REFUSAL-REPORT`; the occupancy rules it inherits are 3.4.\r\n- **Source:** measured by todlando on HFENDULEAM 2026-08-04 while answering doyle's step-1 predicate question on releases#109; ruled into the lane by doyle the same day.\r\n\r\n---\r\n\r\n## 4. Wire / transport\r\n\r\n### 4.1 Envelope HTML-entity codec ordering — `&amp;` decoded LAST\r\n- **Failure:** decoding `&amp;`-entity before the others double-decodes nested entities (`&amp;amp;lt;` → wrong result).\r\n- **Invariant:** ENCODE order amp→first … `<br>`→last; DECODE order `<br>`→first … amp→**last** (`&lt;`,`&gt;`,`&quot;`, then `&amp;`). One sole decode site (at the LLM/stdin boundary); the parser never decodes.\r\n- **spt-core mapping:** `spt-proto` owns the envelope grammar (public SDK, semver + wire-version). This codec contract is a copy-verbatim commodity item (ADR-0001) and a public-API conformance test.\r\n- **Sister cite:** `src/owl/poll.rs:1-73`; `src/common/envelope.rs`.\r\n- **CR-linesafety `[REQ-HAZARD-ENVELOPE-CR-LINESAFE]`:** the EVENT is LINE-FRAMED, so the codec must neutralize raw `\\r` too — `event_body_escape` folds CRLF/lone-CR to `\\n` (→`<br>`) **before** framing. **Failure (field, 2026-06-08):** a cross-node `spt send` from Windows (`echo` → CRLF) carried a raw `\\r` into the single-line envelope; the receiver terminal did a CR→column-0 overwrite (`</EVENT>` clobbered `<EVENT t`). `\\r` was never line-representable here, so normalizing it is robustness, not an ADR-0001 wire divergence (decoder + amp-last untouched). Belt-and-suspenders: `spt send`/`ring` trim stdin like `notify`.\r\n\r\n### 4.2 Two-slice envelope parser is panic-free and tolerant\r\n- **Failure:** malformed envelope (unclosed/misordered/nested tags) panics or drops output.\r\n- **Invariant:** tags case-sensitive, all optional; no tags → whole body to live slot; unclosed → None for that tag; out-of-order → both still extracted; nested unknown tags preserved verbatim; zero `unwrap` on parsed text.\r\n- **spt-core mapping:** `spt-proto` parser; property-test the robustness rules.\r\n- **Sister cite:** `src/common/envelope.rs:64-92`; tests 99-207.\r\n\r\n### 4.3 Registry stale-entry cleanup precedes lookup\r\n- **Failure:** sender resolves a dead process's stale TCP port → delivery to wrong/dead listener.\r\n- **Invariant:** clean stale entries (dead PID) before/at lookup; spool fallback is the safe path on TCP miss.\r\n- **spt-core mapping:** now spans the **subnet registry** (ADR-0003) — eventually-consistent across nodes. Cross-node staleness is expected; resolution policy (local → most-recent → `id@node`) must degrade to spool/relay fallback on stale hits, and never hard-fail on a stale remote entry.\r\n- **Sister cite:** `src/common/registry.rs:62-78`; `src/owl/send.rs`.\r\n\r\n### 4.4 Deferred rows survive poll drain\r\n- **Failure:** poll `drain_all` flushes a deferred (spool-only) message meant for a hook consumer → message lost.\r\n- **Invariant:** deferred rows are never flushed by the event-stream drain; only `drain_non_deferred_*` / `peek_all` touch them.\r\n- **Sister cite:** CHANGELOG v1.11.20; `src/common/spool.rs`. (See also 1.4.)\r\n\r\n### 4.5 Inbox legacy compat must not double-deliver\r\n- **Failure:** message surfaced via both spool (durable) and legacy inbox files → duplicate or racing delivery.\r\n- **Invariant:** spool is the sole read path at poll time; inbox is write-for-compat only and never read.\r\n- **spt-core mapping:** clean-room — likely drop the legacy inbox entirely. If kept for any compat, preserve \"never read at drain time.\"\r\n- **Sister cite:** `src/common/inbox.rs`.\r\n\r\n### 4.6 Addressable-id charset reserves the address delimiters\r\n<!-- [doc->REQ-HAZARD-ID-CHARSET] -->\r\n- **Failure:** a bare endpoint id that contains `:` or `@` (or a path separator / whitespace / control char) makes the canonical qualified address `[subnet:]id[@node]` (ADR-0006 / REQ-INST-10) ambiguous to parse, and lets a name smuggle into a perch directory path. Once permissive ids exist in the wild, tightening later needs a migration.\r\n- **Invariant:** every addressable id/name is validated to `[A-Za-z0-9_-]` + Hiragana/Katakana/CJK only, length `1..=64`, **at every creation seam** (`ready` start, `api bind`, `api listen`, `api worker-start`). `:` and `@` are permanently reserved as address delimiters; reads of existing perches are never re-validated. Enforce now (pre-M3/M4) so no permissive id-data accumulates.\r\n- **spt-core mapping:** `spt_proto::id::validate_endpoint_id`; called at the four creation seams. The existing Psyche (`<parent>-psyche`) / Worker (`<parent>-w<N>`) suffix scheme uses only `-` + alphanumerics, so composite ids validate.\r\n\r\n### 4.7 Concurrent SQLite openers must not fail with \"database is locked\"\r\n<!-- [doc->REQ-HAZARD-REGISTRY-CONCURRENT] -->\r\n- **Failure:** two endpoints on one machine open the same SQLite store at once (e.g. two `ReadyAgent::start` calls registering simultaneously) and one fails outright with `SQLITE_BUSY` / \"database is locked\" → spurious registration/spool failure. Surfaced as a parallel-test flake in `two_agents_exchange_message_tcp_and_spool`, but the bug is real concurrency, not test-only.\r\n- **Invariant:** `busy_timeout` is set **before** any lock-taking statement on every connection. Switching `journal_mode=WAL` takes a brief exclusive lock; with the default 0ms timeout it fails immediately under contention, so the pragma order is load-bearing: `Connection::open` → `busy_timeout` → `journal_mode=WAL` → `CREATE TABLE …`. WAL alone is insufficient (concurrent *writers* still serialize; they must *wait*, not error).\r\n- **spt-core mapping:** `spt_store::registry::open_registry` + `spt_store::spool::open_spool_at`; both set `busy_timeout=5000` first. Any future SQLite store (history Path B, instance registry) must follow the same ordering.\r\n\r\n### 4.8 Registry merge ordered by epoch, never wall-clock (red-team #8)\r\n<!-- [doc->REQ-HAZARD-REGISTRY-EPOCH-LEASE] -->\r\n- **Failure:** the per-subnet registry replicates `endpoint_id → [instances]` eventually-consistently across nodes. Under a partition or clock skew, a lagging node re-announces a stale `Active` for an endpoint that has actually gone `Offline`. If the merge ordered updates by wall-clock (or \"last write wins\"), the stale `Active` overwrites the newer `Offline` and resolution routes a message to a dead/wrong instance.\r\n- **Invariant:** the merge precedence key is a **per-node monotonic epoch counter** (`spt_store::epoch::EpochSource`, persisted, strictly increasing, NEVER wall-clock), compared version-vector style per `(endpoint_id, node)`: an incoming update wins **iff its epoch is strictly greater** than the stored one for that node; equal or lower is dropped as stale. So a newer `Offline` (higher epoch) can never be clobbered by a lagging `Active` (lower epoch), and an idempotent equal-epoch replay is a no-op. Wall-clock is at most a human tiebreaker hint inside a flagged conflict, never the ordering authority. The same epoch source unifies with the D6 sync-precedence concurrent-write detection (#7).\r\n- **spt-core mapping:** `spt_net::net::registry::SubnetRegistry::merge_instance` (the lease) + `spt_store::epoch::EpochSource` (the counter). Cross-node replication of the merge wires at D4; the merge seam is identical for local and wire-delivered updates. Chaos/two-host verification = D9.\r\n\r\n### 4.9 SQLite stores must create their parent dir — SQLite won't\r\n<!-- [doc->REQ-HAZARD-REGISTRY-DIR-CREATE] -->\r\n- **Failure:** `Connection::open` creates the database FILE but never its parent DIRECTORY. On a fresh home (first boot, fresh CI `_work` dir) a registry op that runs before any perch-creating op (`create_dir_all` side effects) fails `SQLITE_CANTOPEN` — \"unable to open database file …owlery\\.registry\". Timing-dependent: whichever code path touches the home first decides the outcome, so it surfaces as a parallel-test flake (bind-first tests losing the dir-creation race to perch-first tests). Bit the hfenduleam CI leg twice (2026-06-03/04, four spt-msg unit tests at once on the second strike) before being run to ground; a slow runner filesystem (AV scanning fresh dirs) widens the window but is not the cause.\r\n- **Invariant:** every SQLite store's open path `create_dir_all`s its parent dir itself, best-effort, before `Connection::open` — never relying on another subsystem having materialized the home first. (Mirrors the spool, which always did this; the registry didn't.)\r\n- **spt-core mapping:** `spt_store::registry::open_registry` (`create_dir_all(owlery)` before open). `spt_store::spool::open_spool_at` already creates its perch dir. Any future SQLite store must do the same — pair this with the 4.7 pragma ordering on every new store.\r\n\r\n### 4.10 Dead node identities leave immortal registry rows  `[REQ-HAZARD-REGISTRY-GHOST-ROWS]`\r\n<!-- [doc->REQ-HAZARD-REGISTRY-GHOST-ROWS] -->\r\n- **Failure:** the registry's only superseding mechanism is the per-`(endpoint_id, node)` epoch lease (4.8) — a row is replaced only by a newer row *from the same node*. When a node identity dies permanently (machine retired, or `node.key` regenerated so the \"node\" never speaks again), its rows are never superseded and never expire: they sit in the in-memory registries and the `identity/registry/<subnet>.json` snapshots forever. A bare-id send then resolves the same endpoint id on both the live and the dead identity and refuses with a **phantom `AcrossNodes` ambiguity** — unfixable by the user, because no qualifier reaches a node that no longer exists. Hit live in the M7 acceptance run (2026-06-06): gravity paired under two identities (09ef…, then 03854a… after its key universe flipped during the sudo experiments); the dead identity's `sergey` row made bare `spt send sergey` refuse on HFENDULEAM.\r\n- **Invariant:** registry rows authored by a **silent** peer node decay: a node not *heard* (admitted inbound feed — the M7 D2 heard-map, REQ-SUBNET-1) within the eviction window (`registry_evict_after_ms`, default 300s ≈ 10 default pump cadences) has its rows **evicted** from every subnet registry, snapshots rewritten. Own rows never decay (the node always hears itself implicitly — it authors them each pump tick). Eviction is safe under the lease: v1 has **no transitive gossip**, so any future update for a node comes from that node itself, alive, re-inserting from its durable `EpochSource` within one cadence — there is no lagging third-party replay to mis-order against. A merely-offline node loses its rows after the window and reconverges on return; meanwhile resolution honestly reports it absent instead of poisoning bare-id sends.\r\n- **spt-core mapping:** `spt_net::net::registry::SubnetRegistry::evict_nodes` (model) + `spt_daemon::registryhost::RegistryHost::evict_silent_peers` (heard-map TTL) driven from the registry pump tick (`peerloop`). Trust rows are NOT auto-evicted (trust is a user decision; a stale trust row only costs dead dials) — pruning those is a separate verb.\r\n- **Source:** M7 acceptance run 2026-06-06 (DEFERRED.md \"Ghost registry row eviction\"); the AMBIGUOUS render fix rode along.\r\n- **Mesh note (ADR-0017, 2026-06-08):** the subnet mesh **preserves** this invariant rather than superseding it. \"No transitive gossip\" sharpens to **no transitive *row* gossip** — the mesh relays only the member *roster* (discovery), while registry **rows stay own-authored and are fetched directly** from each member over a handshake. So \"any future update for a node comes from that node itself, alive\" still holds and the eviction lease is untouched. (The plan's rejected alternative — signed transitive *row* relay — would have broken this; roster-only relay was chosen precisely to keep it.)\r\n\r\n### 4.11 Advertisement-epoch reset strands a node  `[REQ-HAZARD-EPOCH-RESET]`\r\n<!-- [doc->REQ-HAZARD-EPOCH-RESET] -->\r\n- **Failure:** a node whose advertisement-epoch counter resets (the durable `EpochSource` file lost/recreated) re-advertises with LOW epochs; peers hold a higher last-seen epoch for that `(endpoint, node)` lease and drop every fresh row as **stale** — the node advertises into a void until its counter outruns its own history. Nothing renders the cause: the node looks healthy locally, peers simply never update.\r\n- **Invariant (mitigation by construction, common case):** the common trigger — a full reinstall / identity regeneration — is covered by the **re-pair trust overwrite** (M8 decision 13, REQ-SUBNET-7): a completed ceremony presenting the same label + machine id evicts the superseded identity's trust AND registry rows on the seed-holder, and the peer-side epoch memory **dies with the deleted row** — the re-paired node's fresh epochs land on a clean lease. M8 acceptance 7 verifies this explicitly (the epoch sub-check).\r\n- **Residual (documented, guard deferred):** the narrow slice — epoch file lost while the node *identity* is kept (manual state surgery, partial restore from backup) — has no guard; it waits for a field hit before one is designed (M8 decision 24). `REQ-HAZARD-EPOCH-RESET` is minted inactive (TRACEABILITY rule 5) as the tracking hook. If hit: symptoms are one node's endpoints frozen-stale on every peer while its own views are fresh; recovery today is re-pairing the node (rides the common-case eviction above).\r\n- **spt-core mapping:** epoch mint = `spt_store::epoch::EpochSource` (`identity/epoch.json`); the lease = the per-`(endpoint, node)` epoch compare in `spt_net::net::registry`; the eviction that clears peer-side epoch memory = `registryhost::repair_evict_superseded` + `RegistryHost::consume_repair_evictions`.\r\n- **Source:** minted at M8 ratification (decision 24), recognized as a class during the 2026-06-07 pump diagnosis / re-pair overwrite design — not yet field-hit in its residual form.\r\n\r\n---\r\n\r\n## 5. Platform-specific\r\n\r\n### 5.1 Windows PID recycling false positives\r\n- **Failure:** recycled PID reads alive for the wrong process → orphan misclassification.\r\n- **Invariant:** anchor liveness on the stable parent/harness PID; minimal info.json for supervisor-owned perches; mtime grace window (≥60s) masks transient mismatches.\r\n- **spt-core mapping:** broker-held handles supersede PID polling for spt-hosted sessions; keep the grace window for harness-hosted.\r\n- **Sister cite:** `src/live/wrapper/orphan.rs:141-161`; `src/common/list_filter.rs:168-175`.\r\n\r\n### 5.2 Windows EBUSY on atomic rename\r\n- **Failure:** `fs::rename` fails while a handle is (recently) held → registry/marketplace update fails.\r\n- **Invariant:** tmp-write + atomic-rename with retry/backoff; best-effort side-fail; tolerate transient EBUSY.\r\n- **spt-core mapping:** all on-disk state writes (registry, trust store, spool checkpoints) use this pattern.

That `spt` process detach-spawns a **long-lived** child (the daemon via `ensure_running`; a shell binary via `spt shell spawn`). On Windows `CreateProcess` runs with `bInheritHandles = TRUE`, and the spt process's std handles — the caller's pipe write-ends — are inheritable by construction, so the immortal child inherits them even when its *own* stdio is `Stdio::null()`. The caller's pipe read never sees EOF: the capturing caller **hangs forever** (unix is immune — pipe fds are `CLOEXEC`). Paid twice: daemon spawn (guarded at D4a-era `spawn_detached`), then again at M5-D3e when the mock-shell E2E hung `spt shell spawn` for hours.\r\n- **Invariant:** every detach-spawn of a long-lived child inherits only handles it **enumerates**. The default and overwhelmingly common form of that is `bInheritHandles = FALSE` (`spt-daemon::daemon::detached_no_inherit`) — zero handles flow, whatever the pipe's depth in the ancestry. Stripping `HANDLE_FLAG_INHERIT` from the spawner's *std* handles is NOT sufficient: a grandparent capture's pipe sits in the handle table as a stray inheritable handle and still flows through every **bare** `bInheritHandles = TRUE` hop (the first guard shipped that way and was wedged by exactly this — a daemon spawned three layers deep held the pwsh-level pipe of the CI/test harness).\r\n- **The one permitted TRUE (amended 2026-07-26, RESIDENT-SERVICE W1):** a spawn that must capture the child's output may pass `bInheritHandles = TRUE` **only** paired with an explicit `STARTUPINFOEX` + `PROC_THREAD_ATTRIBUTE_HANDLE_LIST` allowlist — the Win32 contract honors the list only under TRUE, so the earlier phrasing (\"flipping TRUE is refused\") forbade its own mechanism and was unimplementable. The hazard was always *unenumerated* inheritance, and the list **is** the enumeration: only the named handles flow, so a grandparent's pipe cannot reach the child at any depth — strictly stronger than what FALSE achieves incidentally. A **bare** TRUE, with no attribute list, remains REFUSED. Today the only such path is a supervised `[service]` spawn with startup capture (one-entry list, one file handle), and it is pinned behaviorally, not by flag-reading: `a_captured_spawn_inherits_only_the_handle_in_its_allowlist` plants a deliberately inheritable handle that is NOT in the list and fails if the child receives it.\r\n- **spt-core mapping:** `spt-daemon::daemon::spawn_detached` (the daemon) and `spt-daemon::shellhost::launch_shell` (the relay-receipt shell binary). Any future long-lived detached spawn (manifest-template children included) must use the same no-inherit spawn, or the enumerated form above where it genuinely must capture output.\r\n- **Source:** spt-core, M5-D3e (`shell_e2e.rs` hang, 2026-06-04, twice — once per guard generation); Rust `Command` restricts *its own* created stdio handles but a parent's inheritable handle table still flows.\r\n\r\n### 5.7 Elevated commands spawn the daemon with the wrong token  `[REQ-HAZARD-ELEVATED-DAEMON-SPAWN]`\r\n<!-- [doc->REQ-HAZARD-ELEVATED-DAEMON-SPAWN] -->\r\n- **Failure:** membership-implies-reachability made *every* `spt` invocation a potential daemon spawner (`ensure_running`), including the elevation-gated ones (`subnet create`/`join`, REQ-SUBNET-4). The spawned daemon inherits the spawner's token. **Windows:** an elevated `subnet create` auto-starts an ELEVATED daemon whose named pipes deny unelevated clients — every subsequent unelevated `spt` reads \"not running\", tries to spawn its own daemon, and dies on bind Access-denied; the user had to taskkill (hit live, M7 acceptance 2026-06-06). **Linux:** a sudo'd command spawns a root daemon and/or root-owned state — and because sudo flips `$HOME`, the daemon can mint a *different node identity* in root's universe (the very key-flip that produced the 4.10 ghost rows).\r\n- **Invariant:** the daemon **always runs unelevated in the invoking user's universe**, regardless of which command spawns it. Two enforcement points sharing one seam: (a) `spawn_detached` de-elevates the child — Windows: the UAC **linked token** (`TokenLinkedToken` → `DuplicateTokenEx` → `CreateProcessWithTokenW`; inherits no handles, so 5.6 holds by construction); Linux: drop to `SUDO_UID`/`SUDO_GID` with `$HOME`/`$USER`/`$LOGNAME` reset to the invoking user's (passwd lookup); (b) a `Daemon::run` entry guard catches a *directly* elevated `spt daemon` — Linux drops privileges in-process before touching any state; Windows respawns de-elevated and exits. When no unelevated identity exists to drop to (UAC disabled, genuine root login, SYSTEM), the daemon runs as-is with a loud warning — a consistent universe, never a torn one. Elevated one-shot *clients* talking to an unelevated daemon are fine (downward connects work); the daemon side is the invariant.\r\n- **spt-core mapping:** `spt-daemon::deelevate` (the OS-split seam) consumed by `daemon::spawn_detached` + the `Daemon::run` entry guard. The fuller Linux elevation model (install symlink + default-account election) is deferred (DEFERRED.md, M8).\r\n- **Source:** M7 acceptance run 2026-06-06 (DEFERRED.md \"Non-admin daemon spawn\"); interim field rule was \"bring the daemon up unelevated FIRST\".\r\n\r\n<!-- [doc->REQ-HAZARD-CHILD-CONSOLE-FLASH] -->\r\n### 5.8 Console children of the console-less daemon flash visible windows  `[REQ-HAZARD-CHILD-CONSOLE-FLASH]`\r\n- **Failure:** the daemon runs DETACHED (no console, 5.6/`detached_no_inherit`). Any console-subsystem child it spawns (`git`, `taskkill`, manifest hook commands) gets a **fresh conhost with a visible window** — piped/null stdio does NOT prevent it. Field shape: the 60s sync pump's two git calls (`for-each-ref` + `rev-parse`) flashed two blank windows per minute on the user's desktop (2026-06-06).\r\n- **Invariant:** every short-lived console child spawned from daemon-reachable code sets `creation_flags(0x0800_0000)` (`CREATE_NO_WINDOW`). Long-lived detached children use `detached_no_inherit` (already `DETACHED_PROCESS | CREATE_NO_WINDOW`); de-elevated spawns use `CREATE_NEW_CONSOLE + SW_HIDE` (5.7 — `CreateProcessWithTokenW` rejects `CREATE_NO_WINDOW`, error 87).\r\n- **Test seam caveat:** window-absence is unobservable from a consoled test runner — the child inherits the runner's console and never creates a window, flag or no flag. Unit coverage asserts the flagged spawn still works (the error-87 \"flag combo breaks spawn\" regression class); window-absence was verified live by process-watch capture.\r\n- **spt-core mapping:** `spt-store::gitrun::run_git` (every BranchStore/ContextStore git call), `spt-daemon::shellhost::kill_shell_pid` (taskkill), `spt-runtime::run_bounded_command` (manifest hook commands), `spt-runtime::ManifestRuntime::command_for` (the one shared builder behind `spawn_session` + `run_bounded_stdin` — the notif pump's `spawn_notif_command` and the live agent's psyche/echo/turn spawns), `spt-daemon::shellwake` (already guarded). The flag lives in each shared builder, not per call site, so the invariant holds for every ManifestRuntime spawn by construction.\r\n- **Source:** spt-core field bug, 2026-06-06 — two blank windows flashing every 60 seconds on a desktop workstation, caught by process-spawn watcher (git.exe parent=spt daemon, conhost.exe child each).\r\n\r\n### 5.9 `Instant - Duration` underflow-panics on a freshly-booted host  `[REQ-HAZARD-INSTANT-UNDERFLOW]`\r\n- **Failure:** `Instant::now() - Duration::from_secs(N)` panics `overflow when subtracting duration from instant` when the process's monotonic clock is younger than `N` — i.e. the host booted less than `N` ago. The peer pump primed its cadence legs with `Instant::now() - 86_400s` to mean \"everything due now\"; on a Windows runner with sub-24h uptime the pump thread panicked at startup, so the subnet never converged (CI `pump_and_dispatch_self_drive_the_subnet` failed, run 27082417706). It is *environment-conditional* — green on any host up longer than the offset, red below it — so it slips local dev and only bites a fresh CI box or a just-rebooted machine.\r\n- **Invariant:** NEVER compute an instant in the past by subtracting from `Instant::now()`. Represent \"never run / due now\" as `Option<Instant> = None` and gate on forward `now.duration_since(past)` only (`peerloop::due`). No backward instant arithmetic anywhere in scheduling.\r\n- **Test seam caveat:** the convergence E2E only reproduces on a sub-offset-uptime host (it passed everywhere with >24h uptime). The deterministic guard is the `due(None, ..)`/`due(Some(now), ..)` unit on the extracted gate — it asserts first-tick-due with zero instant subtraction, independent of host uptime.\r\n- **spt-core mapping:** `spt-daemon::peerloop::due` (the sole cadence gate behind `due_reg`/`due_notif`/`due_sync`/`due_upd`); cadence legs are `Option<Instant>` seeded `None`.\r\n- **Source:** spt-core CI failure, 2026-06-07 — Windows runner `hfenduleam` (just booted) panicked the peer pump at the v0.1.1 release gate.\r\n\r\n### 5.10 `sudo spt` dead-ends on a user-local install (secure_path)  `[REQ-HAZARD-SUDO-SECURE-PATH]`\r\n- **Failure:** the elevation-gated commands (`subnet create` / `subnet join` / `show-code`) refuse when unelevated and tell the user to \"run as administrator / root\". The user types the obvious `sudo spt subnet create FOO` → `sudo: spt: command not found`. `spt` is a user-local install (`~/.local/bin`, `~/.cargo/bin`), and sudo's `secure_path` (a `/etc/sudoers` default) does NOT include those dirs, so a bare command name doesn't resolve under sudo. The guidance is a trap: it names an action that cannot work for the common install shape. Field-hit on KITSUBITO at the v0.1.1 ship.\r\n- **Invariant:** elevation guidance on Unix emits the binary's **absolute path** under sudo — `sudo /home/u/.local/bin/spt subnet create FOO` — reconstructed from `current_exe()` + the real argv and shell-quoted. An absolute program path is executed directly; `secure_path` only governs bare-name PATH lookup, so the absolute form always resolves. On an interactive Unix TTY the command auto-elevates (re-execs itself under sudo, the elevated child does the work and `main` de-elevates back); non-interactive or sudo-absent falls back to printing the runnable hint. Never emit a bare-name elevation instruction.\r\n- **Companion UX:** the post-de-elevation `DEELEVATED: running as uid N` line is internal state-safety noise — omit it from the user-facing CLI path (it confused the same field user). The detached daemon's own de-elevation log line is fine (it lands in the daemon log, not the terminal).\r\n- **Test seam caveat:** the sudo re-exec needs a real `sudo` + TTY (not hermetic). The deterministic guard is the pure `elevation::sudo_argv` / `print_hint_command` (assert an absolute exe path, never a bare name, + shell-quoting on the printed line) and the `decide_elevation_path` matrix (which picks inline-sudo only on an interactive Unix TTY); the exec leg is manual/kitsubito-verified.\r\n- **spt-core mapping:** `spt::elevation::{sudo_argv, print_hint_command, decide_elevation_path}` (pure — generalized from the M12-W4 self-elevation seam, 5.11), `spt::cli::{try_auto_elevate, with_elevation_hint}` wired into `cmd_subnet_create` / `cmd_subnet_join` / `cmd_subnet_show_code`; `spt::main` de-elevation drop silenced.\r\n- **Source:** spt-core field report, 2026-06-07 — `reavus@KITSUBITO`, `spt` in `~/.local/bin`; the absolute-path `sudo` invocation was confirmed working before the fix landed.\r\n\r\n### 5.11 Self-elevating re-launch must re-run verbatim, never widen / inject / loop  `[REQ-HAZARD-SELF-ELEVATE]`\r\n- **Failure class:** a privilege-gated command (`subnet create` / `join` / `show-code`) self-elevates by re-launching itself with privilege (Windows UAC `runas`, Linux `pkexec` / a terminal-emulator `sudo`, or inline `sudo`). A careless re-launch is a security hole: widening the privilege scope (adding args), resolving the binary by a bare name (a PATH/`secure_path` hijack runs an attacker's `spt`), interpolating a crafted arg into a shell string (`sh -c \"… $id …\"` injects a second command), or re-elevating the already-elevated child (an infinite UAC/polkit loop). The user's UAC/polkit/sudo prompt is the ONLY consent gate — the mechanism must never bypass or widen it.\r\n- **Invariant:** self-elevation re-runs the **EXACT** original invocation with the binary's **ABSOLUTE** exe path — never adding/altering args, never a PATH-resolved bare name, never a shell-interpolated string. Every launcher passes an **argv array** (`Command::new(prog).args([...])`, never `sh -c`); the Windows `ShellExecuteW` params string (which is inherently one string) MSVC-quotes each verbatim arg so `CommandLineToArgvW` round-trips it as a single token. The elevated child drops state back to the user (composes with the 5.7 de-elevation) and **never re-elevates**: `decide_elevation_path` returns `AlreadyElevated` whenever the process is `Elevated`, on every OS (loop-safety). The unprivileged parent never pipes/captures the elevated child's stdout across the privilege boundary — the child is self-contained (on Windows it self-pauses a fresh console via `GetConsoleProcessList` so its output stays legible). The print-hint floor prints the absolute-path command too.\r\n- **Test seam caveat:** the real launch needs a UAC/polkit/sudo prompt (not hermetic) — manual-verify. The deterministic guards are the pure `decide_elevation_path` matrix (loop-safety: `AlreadyElevated` on every os; the os×env path order) and the argv builders (`sudo_argv` / `pkexec_argv` / `terminal_argv` assert absolute-exe + verbatim args + array; `windows_runas_params` asserts MSVC-quoting with no `cmd /c` interpolation; the crafted-arg test asserts a shell-metachar arg stays one element / one quoted token).\r\n- **spt-core mapping:** `spt::elevation::{decide_elevation_path, sudo_argv, pkexec_argv, terminal_argv, windows_runas_params, print_hint_command, ElevatePath}` (pure), `spt::cli::{try_auto_elevate, launch_uac_window, pause_elevated_console_if_fresh, program_on_path, first_terminal_emulator}` (impure launchers) wired into `cmd_subnet_create` / `cmd_subnet_join` / `cmd_subnet_show_code`. Companions: 5.10 (the Unix abs-path-under-sudo facet) and 5.7 (the elevated child's de-elevation drop, which this composes with).\r\n- **Source:** M12-W4 design (subnet QR + self-elevating window), doyle ruling `M12-W4-RULING.md` Q6 — a privilege-escalation feature carries a mandatory hazard REQ.\r\n\r\n<!-- [doc->REQ-HAZARD-WIN-PTY-PROGRAM-RESOLVE] -->\r\n### 5.12 Native-PTY spawn of a bare program runs the wrong (non-PE) file on Windows  `[REQ-HAZARD-WIN-PTY-PROGRAM-RESOLVE]`\r\n- **Failure:** `portable-pty`'s ConPTY spawn resolves a bare program name with a `which` that takes the FIRST `PATH` match. A node/npm CLI installs as BOTH an extensionless shebang shim (`ccs`, for Git Bash) and a Windows launcher (`ccs.cmd`) in the same dir; portable-pty picks the extensionless `ccs`, and `CreateProcessW` then tries to execute that non-PE file and fails with **os error 193** (\"%1 is not a valid Win32 application\"). Live failure: `spt endpoint run claude-spt:ccs` → `CreateProcessW C:\\nvm4w\\nodejs\\ccs` 193 (operator, 2026-06-16). The same bites any harness/shell whose `[session.self]`/`[shell].spawn` names a `.cmd`/`.bat`/`.ps1`-backed command — `CreateProcessW` cannot execute a batch or PowerShell script directly.\r\n- **Invariant:** spt-term resolves the program ITSELF before handing it to `CommandBuilder`, bypassing portable-pty's `which`. A bare name is searched over `PATH` × `PATHEXT` (whose default order already prefers `.EXE`/`.COM` over `.BAT`/`.CMD`), then an extensionless fallback. A non-PE target is wrapped in its interpreter: `.cmd`/`.bat` → `cmd.exe /d /c <path>`, `.ps1` → `powershell -NoProfile -File <path>` (the wrap args precede the caller's args); a real executable spawns directly; an unresolvable name passes through unchanged (never makes a working case worse). Unix is a passthrough — `execve` honours a shebang on an extensionless script. Applied at the ONE `CommandBuilder` chokepoint (`PtySession::spawn_program_in`), so every broker harness + shell spawn is covered. *Caveat:* the `cmd.exe /d /c` wrap inherits cmd's argument-quoting rules for paths/args containing spaces or cmd metacharacters — adequate for the common install-path case; a fully robust cmd-quoting pass is a follow-on if it bites.\r\n- **spt-core mapping:** `spt_term::winprog::{resolve_for_pty, resolve_in}` (the pure PATHEXT-precedence kernel + the Windows env wiring), wired into `spt_term::pty::PtySession::spawn_program_in`.

The rename's directory **metadata** is journaled durable, but the tmp file's **data blocks** are still in the page cache. A hard reset (power loss, forced reboot) between the two flushes lands the rename but loses the data → the file reappears at its **full length filled with NUL**. Field incident: after a machine restart `owlery/hall-a/info.json` was 360 bytes of all-NUL (the nested psyche record 125 bytes all-NUL); `Get-Content` renders blank, `Format-Hex` shows the zero-fill. A wiped-but-present record then read as a live ONLINE endpoint for days (compounded by 5.14).\r\n- **Invariant:** for records whose loss is **unrecoverable**, flush data to stable storage **before** the rename publishes the name — `File::create(tmp)` → `write_all` → `sync_all()` → `rename_with_retry`. Then a crash yields the complete old file OR the complete new file, never a NUL husk. (A file of correct length that is ALL-NUL is the diagnostic tell of this class — a non-fsync'd write caught by a hard reset.) **Durability is SCOPED, not blanket.** `fsync`ing *every* atomic write serializes a durable flush behind each of the ~26 `atomic_write` callers — and for `info.json` the flush lands under the per-perch `.info.lock` (the **W1b lock-across-fsync wedge shape**, §6-era) — which stalls daemon bringup 4–6× so the endpoint misses its ONLINE window. Scope the fsync to the record, not the writer: only authoritative per-perch records and one-shot identity material are durable; reconstructible state (registry snapshots, epoch counters, peer caches, the release cache) stays non-durable — a post-crash NUL husk parse-fails to *absent* and is regenerated / re-gossiped, and the 5.14 read-side already makes a corrupt record harmless at every seam.\r\n- **spt-core mapping:** `spt_store::atomic::atomic_write_bytes_durable` / `atomic_write_string_durable` are the opt-in durable siblings; the default `atomic_write_bytes` / `atomic_write_string` stay non-durable. Durable callers are exactly `spt_store::info::write_info` (the perch record — the hall-a surface), `spt_store::nodeid` (the node seed — corrupt is node-bricking, never regenerated), and `spt_daemon::machineid` (minted-once machine id — a NUL husk would silently re-mint a different id). Reader-side handling of an already-corrupt record is the sibling 5.14. **Canary:** `attach_wedge_e2e` is the regression guard — a blanket fsync fails it (bringup misses the 20s ONLINE budget); keep durability scoped so it stays green.\r\n- **Source:** field diagnosis 2026-07-01 (operator, post-v0.19.0 restart) — counter-39 bug #2; blanket-fsync perf regression pinned + scoped by the gate rig (doyle), same date.\r\n\r\n<!-- [doc->REQ-HAZARD-CORRUPT-PERCH-COHERENCE] -->\r\n### 5.14 Corrupt info.json read as ABSENT → fail-open readers gossip a wiped perch ONLINE  `[REQ-HAZARD-CORRUPT-PERCH-COHERENCE]`\r\n- **Failure:** three readers each collapsed a **corrupt** (present-but-unparseable) `info.json` into their fail-open ABSENT default, so a NUL-wiped perch (5.13) read as permanently live: `is_perch_alive` returned `true` (unreadable ⇒ interim-alive), `advertised_status` then saw alive + no resting record ⇒ `Active`, and the daemon self-gossiped that Active row every round (epoch 173k+). Result: `hall-a`, dead since a machine restart, showed ONLINE in `spt whoami` and on every remote picker.\r\n- **Invariant:** CORRUPT ≠ ABSENT. A record that EXISTS but stays unparseable across the retry budget is a **destroyed** record — never a live endpoint. `is_perch_alive` reads corrupt ⇒ **not alive** (ABSENT keeps interim-alive parity — the ONE case that stays true); `advertised_status` then lands corrupt in the cold arm ⇒ **Suspended**, never Active/Dormant.

Two processes writing the SAME target concurrently — traced at bind ~700µs apart: the daemon's `mutate_info` RMW and `spt api bind`'s `establish_perch` — both create the same `info.json.tmp`; whichever renames first CONSUMES it, and the loser's `fs::rename` hits `NotFound` (os error 2). `NotFound` is non-transient in `rename_with_retry`, so it surfaces as a hard write error: `establish_perch` returns `BindError::Io` *after* having written the record, mock-session's bind-is-fatal check `exit(1)`s, the harness dies, and the endpoint never reaches ONLINE. A microsecond window that existed forever (bare `fs::write` + rename back-to-back) — the 5.13 `sync_all` widened create→rename ~50× (to ~4ms) and made the collision near-certain *exactly at bind*, which is why the durable-perch-record change unmasked it (deterministic wedge, not a perf regression).\r\n- **Invariant:** concurrent atomic writers to the same target must never share a tmp name. Stage a **unique** tmp per write — `{name}.tmp.{pid}-{seq}`, `seq` from a process-local static `AtomicU64` (no clock, no rand → resume/replay-safe) — on BOTH the durable and non-durable paths (the collision is generic to `atomic_write`, not the fsync).

At bind the two writers race (~700µs apart): the daemon RMW reads the PRE-BIND record, bind's `write_info` renames the full record in (`state=live_agent`, `controllable=Some(true)`, `session_id`), then the RMW writes its STALE pre-bind snapshot back plus a `status=online` stamp. The surviving `info.json` is a **pre-bind shape carrying `status=online`** — bringup passes (it sees ONLINE), the broker serves the session, then on child death `reconcile_hosted_liveness` reads `state != \"live_agent\"` (or `controllable != Some(true)`) and *silently `continue`s* — the dead endpoint is latched ONLINE forever. This resurrects counter-39 #2's dead-but-ONLINE field surface through a brand-new path. Once-loud, now-silent: 5.15's unique tmp turned the previously-`os-error-2` collision into a clean last-writer-wins, and the 5.13 durable fsync (inside the RMW read→write window) made the interleave near-certain on a normal-speed disk. The race predates all of this (v0.19.0-era) — the old fixed tmp made it fail LOUD and non-durable kept the window µs-narrow.\r\n- **Invariant:** every `info.json` writer serializes under the one per-perch `.info.lock`. A whole-record write (`write_info`) takes the lock exactly as the RMW (`mutate_info`) does — a unique tmp only makes concurrent writes *last-writer-wins*, which is safe ONLY if the writers are serialized (cross-ref 5.15). A multi-step read→check→write (bind's establish) must hold ONE lock acquisition across all three (a true compare-and-set) — check-then-write with the lock dropped in between still interleaves a stamp. Readers stay lock-free (the atomic rename already gives a complete old-or-new record). Holding `.info.lock` across the durable fsync is ms-scale on these infrequent record writes (the same thing every `mutate_info` already does), NOT the per-keystroke W1b lock-across-fsync shape.\r\n- **spt-core mapping:** `spt_store::info` — `write_info` now acquires the sentinel then calls a private `write_info_unlocked` (and `mutate_info` — the public RMW primitive — calls the unlocked writer while holding its own lock, so no double-lock deadlock); `info::establish_locked(perch, build)` runs the bind's read→check→build→write as one locked CAS, called by `spt::api::startup::establish_perch`. The other read-modify-write callers were audited and the two that mutate a load-bearing field were converted to the `mutate_info` CAS: `spt::api::reporting::cmd_boundary` (rc-rebind session-id rotation) and `spt_store::home::adopt_for_unset` (home-subnet adoption; the `is_none()` re-check runs inside the closure). **Deliberately parked (known unlocked-RMW residue, honest coverage):** `spt_msg::listener::write_busy` (BUSY-pid stamp — self-healing: re-marked next delivery, recency next tick) and `spt_store::rename::rewrite_id` (rare operator rename ripple) still do a raw read→write; a lost update there self-heals or is operationally rare, so they are left as follow-ups. `spt_msg::ready::start_homed` (harness-hosted `ready`/`listen` bind) is the same read→build→write *shape* as `establish_perch` but is a single-writer context (the daemon does not host/stamp a harness-hosted ready agent concurrently at its own bind), so it is left as-is — revisit if a daemon-hosted path ever stamps it. Regression guard: `write_info_racing_mutate_info_never_lost_update` — a `Barrier`-aligned RMW-stamp vs full-bind-record write hammer on one perch asserting the full record's fields never vanish under a racing stamp (reds on the unlocked-write code, greens after the lock).\r\n- **Source:** RCA 2026-07-01 (doyle gate rig) — differential (baseline PASS / 77beeac+baseline-atomic PASS / fe385f5 2/3 FAIL) isolated the atomic rework as the delta; `reconcile_hosted_liveness` emitting ZERO `LIVENESS_RECONCILE_OFFLINE` lines for the dead victim over 20s pinned the silent-skip. The unique-tmp fix worked (bringup + serve fine) but exposed this deeper pairing.\r\n\r\n### 5.17 `powershell` never executes under our detached spawn — a silent no-op that costs every spawn-rig builder the same three runs\r\n- **Failure:** a test rig that spawns `powershell -Command …` through `daemon::detached_no_inherit*` (`DETACHED_PROCESS`, no console, no inherited handles) gets a process that **starts and exits having run nothing** — not even a bare `Set-Content`. No error, no output, exit status unremarkable: the rig reads as \"my code did not do the thing\" when in fact the *fixture* never ran. Measured 2026-07-26 while building the `[service]` supervision gates: three consecutive runs burned on a fixture that could not have worked, each one re-diagnosed as a supervisor bug. `cmd /c` and `sh -c` run fine under the identical spawn, so the no-op is specific to the shell, not to the detachment.\r\n- **Invariant (rig discipline, not product code):** spawn-based fixtures use `cmd` on Windows and `sh` on unix — never `powershell`. And find a spawned process's descendants **by parentage** via `spt_store::proc::process_table()` (which returns `(pid, ppid)`), never by asking the child to report them: a grandchild that must cooperate to be found is a rig that cannot observe an *uncooperative* one, which is the case the gate exists for.\r\n- **spt-core mapping:** every spawn rig under `crates/spt-daemon` — `servicehost.rs` (`long_running`/`instant_exit`/`noisy_instant_exit` fixtures, the tree-teardown gate) and any future rig over `daemon::detached_no_inherit_env`. No `REQ-HAZARD-*` id and no regression test **deliberately**: the invariant constrains how tests are written, and the only assertion available would be \"the OS still refuses to run powershell this way\" — an instrument test, which is never requirement evidence. It is numbered here because the cost is paid by whoever writes the *next* rig, and a fact that reads as a bug in your own code is exactly what this document exists to intercept.\r\n- **Source:** RESIDENT-SERVICE W1 leg D (todlando, 2026-07-26); ruled into this document by doyle the same day.\r\n- **Amendment 2026-08-02 (hertz, releases#110 measurement):** the cause is `DETACHED_PROCESS` **alone** — not the no-inherit half, as the entry's parenthetical implied. Measured on HFENDULEAM with raw `creationflags` and fully piped stdio: `powershell -Command \"Set-Content …\"` under `DETACHED_PROCESS` exits **rc=0 having written no file** (it does not execute); under `CREATE_NO_WINDOW` the identical spawn writes the file and returns its stdout. `cmd /c` behaves DIFFERENTLY from powershell and the entry's \"runs fine\" is half-right: `cmd /c echo ran> file` under `DETACHED_PROCESS` **does execute** (file written, rc=0), but a `cmd /c ping` whose stdout is a pipe returns **zero bytes** — cmd runs and its piped stdout is lost. So the rig rule stands, with the sharper statement of it: under `DETACHED_PROCESS`, powershell does not run at all and cmd's **captured output** cannot be trusted. A rig that parses a detached shell's stdout is reading a value that no longer exists — see 5.18 for the concrete false-green this shape would have manufactured.\r\n\r\n<!-- [doc->REQ-HAZARD-TREE-CWD-PIN] -->\r\n### 5.18 A surviving test descendant cwd-pins the tree it ran in — the `.worktrees` skeleton that will not delete  `[REQ-HAZARD-TREE-CWD-PIN]`\r\n- **Failure:** a directory that is some live process's **current directory** cannot be renamed or deleted on Windows, while files *inside* it stay writable. That asymmetry is why the symptom never reads as a file lock: `git worktree remove` fails naming the **directory**, `openfiles` shows nothing, and the tree looks idle. cargo runs each test binary with cwd = the **package root**, so every child a test spawns inherits `<worktree>/crates/<pkg>` as its own cwd — and any child (or **grandchild**) that outlives the test pins that path forever. Result: a silent `.worktrees` skeleton accumulator, each one costing the next agent an afternoon.\r\n- **Mechanism — the common case is a surviving descendant, and it is not the `CREATE_NO_WINDOW` conhost.** releases#110 filed the holder as an *orphaned `conhost.exe` holding the crate root*; measurement on HFENDULEAM 2026-08-02 **refutes** that for the population the rigs mint. `CREATE_NO_WINDOW` does produce exactly **one conhost per console child** (counted by `ParentProcessId`), but that conhost's cwd is **not** inherited: it is launched with a system cwd. Census: **43 readable, all of them `C:\\WINDOWS\\` or `C:\\WINDOWS\\system32\\`, zero under any worktree** (4 unopenable, stated). Held directly: spawning a child with cwd = the package root and then force-killing it leaves the orphan conhost still reading `C:\\WINDOWS\\`. Positive control on a scratch dir — write-inside **OK**, delete **BLOCKED**, kill the **conhost** → still BLOCKED, kill the actual holder → **deletes first try**. The holder in that control turned out to be an orphaned **grandchild** (`PING.exe`, cwd inherited through `cmd`) that survived its parent's kill. **That conhost is a byproduct, never the pin; killing it is not the cure and \"no conhosts\" is not the all-clear.**\r\n- **Amendment 2026-08-02 — the exception, field-refuted before it shipped: a `--headless` ConPTY conhost DOES inherit its creator's cwd, and pins it alone.** The entry previously generalized the census above into \"a conhost's cwd is never inherited\". That is true of the `CREATE_NO_WINDOW` population and false of the ConPTY one, which no rig mints but every terminal-hosting path does.\r\n  - **Field specimen (BAROMETER W4 teardown):** `pid 46556 conhost.exe --headless --width 80 --height 24 --signal 0x214 --server 0x20c`, born during the build, parent dead, PEB cwd `…\\.worktrees\\barometer-w4\\crates\\spt\\` — the **sole** holder. Killing it deleted the tree that had refused to delete.\r\n  - **Reproduced deliberately, both launch paths.** Minted through `CreatePseudoConsole` from a process whose cwd was a scratch dir: the new `--headless` conhost's PEB reads **that dir**, and with it alive — write-inside **OK**, delete **BLOCKED**, then **DELETED** after `ClosePseudoConsole`, nothing else changed. Launched as `conhost.exe --headless` directly with a working directory: same inheritance. The first covers the path the wild specimen took; the second shows the binary takes its launcher's cwd in that mode regardless.\r\n  - **The pty-teardown alternative is excluded causally, not by absence.** \"Zero children\" clears nothing here — a ConPTY client is a child of whoever called `CreatePseudoConsole`, never of the conhost — so killing the conhost could in principle have taken a living client with it. Kill-**order** rig, client deliberately `cd`'d elsewhere so it cannot be the holder: both alive → **BLOCKED**; kill the **client** only → still **BLOCKED**; kill the **conhost** → **deleted**.\r\n  - **A census of live `--headless` conhosts cannot settle this in either direction.** All 8 alive that day read `C:\\WINDOWS\\system32\\` — and their single creator's cwd *is* `C:\\WINDOWS\\system32\\`, so the value inheritance predicts equals the value OS-assignment predicts, on rows uniform in the asserted property. It reads as confirmation of the old claim and carries no information; the deliberate launch is what discriminates.\r\n  - **Elevation is not the discriminator, and neither reader needs it.** Both readers open with `PROCESS_QUERY_INFORMATION | PROCESS_VM_READ` only and, **unelevated**, read ~46–49 of the ~50 conhosts alive. A first pass that reported *no* conhost readable was a parsing fault in the caller, not an access denial — worth stating because \"not readable\" and \"read as `C:\\WINDOWS\\`\" are the same blank row to a careless reader.\r\n  - **Scoped conclusion:** a `CREATE_NO_WINDOW` conhost is never the pin and killing it is never the cure; a `--headless` ConPTY conhost **can be the sole pin**, and there killing it **is** the cure. Neither sentence licenses the other.\r\n- **Triage step — the finder answers WHO pins, never whether it is SAFE TO KILL.** These are different questions and the blocked-delete error is **identical** for both, which is exactly what makes the step worth writing down. Read the holder's identity *before* acting: an **orphaned descendant** (parent dead, no window, no client) → kill it; a **LIVE process — above all an agent's own shell** → `cd` out, never kill. **When the holder is a `conhost.exe`, its COMMAND LINE is the discriminator** — a bare `conhost.exe 0x…` is the `CREATE_NO_WINDOW` byproduct and is never the pin (look behind it for the descendant), while `conhost.exe --headless --width … --server …` is a ConPTY host that can be the pin itself and dies to a kill. Do not read its **child count** as evidence either way: a ConPTY's client is a child of the pseudoconsole's creator, not of the conhost, so \"zero children\" says nothing about what is alive behind it. Live confirmation 2026-08-02: after one worktree cleared, an identical error on a second traced to a working agent's **own pwsh tool shell**, and behind it that agent's **Bash tool** cwd in the same tree (the two hold *separate* cwds, so clearing one leaves the other). Pattern-matching the kill recipe there would have cost a working agent their session. The pin also follows whatever crate the test ran under, not a fixed package.\r\n- **spt-core mapping:** `.github/ci/find-cwd-holders.ps1` — read-only (`PROCESS_QUERY_INFORMATION | PROCESS_VM_READ`, `NtQueryInformationProcess` → PEB → `RTL_USER_PROCESS_PARAMETERS.CurrentDirectory`), no process opened for write or killed; `-Match <substring>` filters by cwd. It reports its **denominator** (readable vs not-openable) because \"0 rows\" from a filter and \"0 rows\" because nothing could be opened are the same output and very different facts — an empty result means \"no pin I could see\", never \"no pin\". `handle.exe` is not on the box by default and does not distinguish a cwd pin from an open handle; `openfiles` cannot see this at all without the reboot-time maintain-objects-list flag. The **prevention** side is teardown completeness — a rig that reaps its own descendants leaves nothing to pin — which is the `REQ-TEST-RIG-DAEMON-TEARDOWN-PROVEN` (#99) class extended to grandchildren, measured by surviving-process count on both arms rather than asserted.\r\n- **Do NOT \"fix\" this with the spawn flag.** Flipping the rigs' `CommandNoWindowExt::no_window()` (`crates/spt/tests/common/mod.rs`) from `CREATE_NO_WINDOW` to `DETACHED_PROCESS` removes the conhost (measured: 1 → 0) but does **not** remove the pin (that conhost is never the holder — the `--headless` ConPTY exception above is a host no rig mints through this helper), and it breaks rigs outright per the 5.17 amendment: `job_escape_e2e::conhost_children_of` shells out to **powershell** through that very helper and falls back to `unwrap_or(0)`, so a detached spawn would make `wmi_daemon_run_has_no_conhost_window` — the guard for `REQ-HAZARD-WMI-DAEMON-WINDOW` — assert \"no conhost\" **vacuously green**, a gate whose failure signature is identical to the fault it guards. Nor can the helper simply hand children a neutral cwd: `bind_cwd_project_e2e` and `resume_template_e2e` deliberately assert on the **inherited** cwd, which is the behavior under test.\r\n- **Source:** hertz, releases#110 — filed diagnosis post-v0.51.0 (2026-08-01); mechanism re-measured and the conhost attribution **refuted** 2026-08-02 (per-parent conhost counts, box-wide conhost cwd census, orphan-grandchild positive control). doyle's live correction the same day supplied the live-shell half of the triage step. **The `--headless` exception is field evidence from todlando** (BAROMETER W4 teardown specimen, the direct-launch inheritance test, and the kill-order rig that excluded pty teardown), reproduced through the `CreatePseudoConsole` path with a delete-blocked/deleted control by hertz, and ruled an in-milestone amend by doyle the same day — the entry was refuted **before** it shipped in a golden run.\r\n\r\n<!-- [doc->REQ-TEST-ENV-ONE-LOCK] -->\r\n### 5.19 Two mutexes over one process-global env var guard nothing between them  `[REQ-TEST-ENV-ONE-LOCK]`\r\n- **Failure:** two test-helper crates each declare their own `static ENV_LOCK` over the SAME process-global variable (`SPT_HOME`). Each serializes its own callers **flawlessly** — which is exactly what makes the arrangement read as correct — and neither serializes helper A against helper B. Whichever writes last wins. Because `spt_store::perch::spt_home()` is **not memoized** (it re-reads the env on every call), a test writes its fixture into home A and reads it back from home B: the store is absent, an empty access baseline is minted over it, and the assertion fails on a policy that was never loaded. Field shape (releases#111): `cargo test -p spt-daemon --lib dispatch::` lost **1–3 of 26 nondeterministically**, `an_unadmitted_asker_is_refused_at_this_nodes_own_seam` reading `Some(offline)` where the rules should have answered `None`.\r\n- **Invariant (rig discipline, like 5.17):** one variable, one lock, **per binary**. A crate may keep its own ergonomic wrapper (`with_home`, `isolated_home`, a `TestHome` guard) but must **never** keep its own mutex over a variable another helper in the same binary also writes. `spt_test_support::env_lock()` is THE lease; crate-local helpers return that guard. It is **not reentrant** — a `TestHome` holds it for its whole lifetime, so one is never constructed inside a body already holding the lease.\r\n- **Why it hides, and where it does not:** invisible under **nextest** (per-test processes) and invisible when a loser is run **alone** (no concurrent holder), so CI's nextest unit lane is structurally blind to it — the cost falls entirely on whoever hand-runs the module during a gate. This is the same \"invisible-by-construction\" property as 5.17, and the reason it is numbered here rather than left to the requirement.\r\n- **The diagnostic that shortcuts it:** the tell is a **path shape the suspected helper could not have produced**. #111's panic printed `<tmp>\\home\\identity\\trust\\access.json` — a `home` SUBDIR, which `with_home` never makes (it points `SPT_HOME` at the tempdir *root*). That single mismatch named the real aggressor (`spt_test_support::TestHome`) faster than reading either helper. Corollary for the filed-mechanism trap: `with_home` holds its mutex across its **entire body**, so \"a sibling `with_home` test retargets the home mid-test\" — the filed story — was impossible; read a helper's lock SCOPE before accepting a race that names it.\r\n- **spt-core mapping:** `spt_test_support::env_lock` (the one lease) consumed by `spt_daemon::test_home::{env_lock, with_home}` and `spt::testutil::isolated_home`. Guard: `test_home::tests::with_home_and_testhome_serialize_on_the_same_lease` — a `with_home` body holds the lease while a second thread attempts a `TestHome`, asserting the thread cannot enter and `SPT_HOME` cannot move, **then** that it does proceed once released (so a shared lock is proven to be a lock, not a deadlock). Reds on the two-lock code, greens on one. **Sweep discipline recorded because one instance of a class is not the class:** the population is every crate declaring an `SPT_HOME` helper INTERSECTED with the binaries that also reach `spt_test_support`; running it found a second live, unreported instance (`crates/spt`'s `testutil::LOCK` beside `cli.rs`'s direct `TestHome`). `spt-live` and `spt-store` depend on `spt-test-support` not at all, and `spt-msg` declares no helper of its own.\r\n- **Source:** releases#111 (filed by doyle from hertz's gate observation, 2026-08-02); filed mechanism refuted and the real root measured the same day — hertz. Cousin class, same date: two builds writing one binary path with nothing guarding between them, which is why the gate recipe now identity-checks the exe hash (doyle, W2 gate).\r\n\r\n<!-- [doc->REQ-POOL-FOREIGN-TREE-REFUSED] -->\r\n### 5.20 Two source trees sharing one cargo target directory fabricate reds that belong to neither  `[REQ-POOL-FOREIGN-TREE-REFUSED]`\r\n- **Failure:** a gate lane and a builder lane both built through `.worktrees/gate-target`. The gate compiled against the builder's mid-seam, half-written artifacts and reported an `E0308` in `psyche_event_turn_e2e` that **vanished on re-run** — a red belonging to neither tree, in a lane whose entire job is to be believed. The reverse is worse and silent: the builder's green was equally untrustworthy and nothing said so. Reproduced small (releases#103): two packages of the same name and version, built from two DIFFERENT paths into one pool, resolve to **one** build-script output dir and overwrite each other.\r\n- **Why it hides:** the sharing is invisible at the point of use. A junction shows as an ordinary `target/` and nothing in cargo's output names the real directory; `CARGO_TARGET_DIR` is quieter still — it does not even leave a directory entry to notice afterwards. Both reach the same hazard, which is why the rule is about the **relationship** (this tree writing into a target owned by another) and never about a path: the incident that motivated the filing pointed `CARGO_TARGET_DIR` at the *primary checkout*, which no rule about `.worktrees/` would have covered.\r\n- **The harm is INTERLEAVING, not simultaneity.** Cargo holds an exclusive `.cargo-lock` for a build's duration, so two builds are never literally concurrent — the second blocks. What bit was one lane's artifacts being invalidated by another **between that lane's own steps**. A lease keyed on a `cargo` process therefore guards nothing: it is stale seconds after every claim, so every crossing reads as a takeover and the refusal can never fire. That shape was designed, measured, and refused.\r\n- **Invariant:** a pool belongs to one source tree. `crates/spt-store/build.rs` enforces it and refuses with `SPT_POOL_FOREIGN`, naming the pool, the owning tree, the lane, the holder pid and the way out. Sequential sharing is correct and cheap — a provably-gone lane is a **loud takeover**, never a refusal, because refusing it would demand a pool per lane (30+ worktrees at a measured 7-15 GB each). Staleness is proven from the **process table plus the birth stamp**; UNKNOWN is not stale and proceeds with a warning. An ownerless pool imprints its first builder, so a developer's own fresh `target/` is never refused. `SPT_POOL_UNCHECKED=1` overrides and says so on every build it allows.\r\n<!-- [doc->REQ-POOL-LANE-IDENTITY] -->\r\n- **A DEAD HOLDER IS NOT A FINISHED LANE `[REQ-POOL-LANE-IDENTITY]`.** The first shape of this guard answered \"has that lane finished?\" from the holder process alone. Measured on this box afterwards: **3 of 3 live pool claims had a dead holder, and one of those three lanes was live.** A holder is an agent session or a rig shell — cleared, re-forked, re-parented as a matter of routine — so its death says nothing about the lane, and reading it as \"finished\" hands the pool to a second tree **mid-lane**, i.e. reaches this very hazard *through* the guard. So the claim records the lane's **git identity** (its branch and the base sha that branch carried at claim time) and the finished question is answered by **ancestry**: in flight while the lane's tip is not contained in the integration head; settled once it is merged, once the branch is gone, or once the branch no longer carries the claimed base — a branch name re-pointed onto other work is the branch-level twin of a recycled pid. **The base sha is also the repo-identity witness:** ancestry is read in the *arriving* tree, so a branch absent from a *different* repository would otherwise read as a finished lane; an unanchored claim answers UNKNOWN, never \"settled\". (Found by its own test, which read `Settled: branch no longer exists` out of a directory that was not a repository at all.) **Precedence is asymmetric:** a live holder may only ever ADD a refusal, ancestry alone may declare a lane settled, and a stamp written before the identity fields existed keeps its old behaviour and says so in the line it prints. **What this arm covers, stated exactly:** the enforcer is the build script of the tree that ARRIVES, never the claim it reads, so a lane is protected when the arriving tree carries this change — coverage grows as trees turn over and is never retroactive (measured: a rig whose arriving worktree sat at the pre-identity sha took the pool over, which is the old behaviour working correctly in an old tree). A version line in the stamp cannot fix that and is refused: the tree that must refuse is the one that does not read the new field, so the reader is the problem and not the record. **Every refusal's remedy must be a command that RUNS** — `xtask` depends on `spt-store`, so any command building the tool goes through the refused pool; measured from the refusal state, a remedy naming a bare `cargo run … pool-release` failed with the identical refusal that printed it. The rule is enforced over the whole population of refusal arms, because it was learned once on one arm and re-broken by the next arm added.\r\n- **The guard's own hazard:** the build script must emit **no** `rerun-if` directive. It is re-run because cargo's fingerprint for its unit carries `CARGO_MANIFEST_DIR`, i.e. on exactly the tree ALTERNATION the guard exists to catch. Measured on byte-identical trees, sequence `A B A A B`: no directives → 4 firings; one `rerun-if-changed` → **1**, and the foreign tree never fired it again. `crates/spt-store/tests/pool_guard_canary.rs` reads the shipped build script and reds if a directive appears — a comment would be a prohibition, not a boundary.\r\n- **Source:** BAROMETER W1/H1 window (doyle + todlando, 2026-08-02); design measured and built by hertz, releases#103.\r\n\r\n---\r\n\r\n## 6.

Two legs, and each is worthless alone. **(a) The record stops lying:** the daemon-side reconciler heals a recorded `online` that 2.6's derivation contradicts, writing `offline` — every cycle, **guarded on an actual change** (a heal that rewrote each tick would be a stream of identical writes and would destroy the record's mtime as a signal). **(b) The restart shape reaches a restoration path:** a once-per-daemon-generation boot sweep — and, for an owner that comes online after that sweep has run, an **owner offline→online edge** in the reconcile loop running the identical body (releases#228) — relaunches an instance when **all four** hold — the adapter section declares `persistent`; the **owner endpoint is online** (an offline owner is owed nothing — that is the line between healing a record and resurrecting a shell nobody is there to drive); the instance is down **in fact** (the derived read, made trustworthy across a pid reuse by 2.6's birth stamp); and its recorded launch **predates the boot instant**. No stamp ⇒ **not restored** (the sweep cannot prove it predates boot); no boot oracle on the platform ⇒ nothing restored at all. The boot instant is derived (Linux `btime`; Windows now − `GetTickCount64`), so a named slack constant absorbs derivation jitter and keeps a process launched moments after boot from reading as a corpse from the previous one. **The once-ness of the sweep is scheduling, not safety** (ruled releases#228): the predates-boot discriminant is what forbids relaunching a force-killed shell, and it is monotone within a machine boot — every launch restamps, a kill never does — so a second trigger evaluating the same conjuncts can only refuse more.

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, `info.json`, `spool.db` and the directory. Silent CLI-side fs ops, no daemon log, no console trace (field 2026-07-27 — emphasys lost a live endpoint and its spool to one timed-out ring).\r\n- **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 the ringer's output**, leaving no trace on either side once the dir is removed. Across a multi-machine subnet that is one agent reading another's mail. Bounded honestly for the record: in the field instance theft did **not** fire — emphasys's 66-second window returned `TIMEOUT` with zero `Replied{…}` — it was available and did not happen.\r\n- **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.\r\n- **Marker-down is not an edge case:** on hosted OMP endpoints the extension owns the listener and publishes busy/idle through `api state`, so marker-down is the **normal steady state during work** — marker-first misjudges healthy endpoints routinely.\r\n- **Invariant:** probe the perch **directory**, not the marker. A dir carrying a **record or a spool** is OCCUPIED — refuse to adopt it. Ambiguity resolves toward refusal, always: an **unreadable** record (corrupt/truncated `info.json`) or an unreadable dir counts as occupied, never as residue, because deletion is irreversible while refusal is recoverable. A pre-existing **empty** dir is refused too — it is not provably ring's own residue (a bringup mid-create owns an empty perch dir for a window, and deleting it is the same race in a different hat). Refusal never blocks and is never silent: the message is delivered, the call declines to block-wait (the reply lands on the caller's own listener), and the caller gets a **distinct** loud report — `RING_PERCH_EXISTS` (record/spool) or `RING_STALE_DIR` (empty; names the path and the manual remedy). Loudness — not a self-heal — is what keeps a permanent refusal from being a silent one. Structural, not advisory: the leaf dir is created with `create_dir` (fails `AlreadyExists`), so a perch appearing between probe and create still cannot be adopted, and the refusal path never calls cleanup.\r\n- **spt-core mapping:** `spt_msg::ring::{probe_perch, setup_ephemeral, ring}`; `RingOutcome::{PerchExists, StaleDir}` rendered by `cmd_ring`.\r\n- **Source:** spt-core field incident 2026-07-27 (emphasys endpoint + spool loss); ruled by doyle, with emphasys's mid-create-race amendment revoking the empty-dir self-heal.\r\n- **Amendment — the perch GC inherits this reasoning EXTENDED, never carved out (doyle, 2026-08-04, releases#109).** A second consumer now deletes perch directories: `spt endpoint gc` (3.5, `REQ-PERCH-GC-RESIDUE-PREDICATE`). Its authority is something `ring` never had — a **positive** statement that the directory carries **no endpoint record at all**, from the store that answers endpoint existence on a node (the owlery tree itself; the perch dir plus its parseable `info.json` IS the endpoint record). That authority does **not** outrank this section's occupancy rules, and the ruling says why: undeliverable-by-construction settles *deliverability*, not *value*, so a recordless dir carrying a **spool** is still refused — that spool is the only surviving copy of whatever was queued, and deleting mail is not a GC's call at any confidence level. A pre-existing **empty** dir is still refused for the reason emphasys's amendment gave: the mid-create window exists for the GC identically, and no still-positive discriminator for \"not mid-create\" exists for an empty dir (there is no create-intent marker, and mtime is out by the GC's own predicate). What the GC *may* delete is therefore strictly narrower than what it may *call* residue, and both refusals are kept honest exactly as this section requires — **loudly**, per path, under distinct tokens (`RESIDUE-WITH-SPOOL` / `RESIDUE-EMPTY`) with the manual remedy named. A refusal also **shields the whole subtree under it** — a nested child that would qualify on its own is reported `SHIELDED-BY-REFUSED-PARENT` and left alone, because refusing a directory has to mean not modifying its CONTENTS either (carving a child out destroys part of what the refusal report asked the operator to look at, and can move the parent's own verdict on the next pass). The one discriminator the GC has and `ring` does not is the **held `.info.lock`**: a NON-empty recordless dir whose per-perch write sentinel is held right now is a bringup mid-create, provably, and is refused (`OCCUPIED-WRITE-IN-FLIGHT`). An empty dir gets no such signal, which is why its refusal stays unconditional.\r\n<!-- [doc->REQ-HAZARD-RING-PERCH-ADOPTION] -->\r\n\r\n### 3.5 `is_perch_alive` is INVERTED on perch residue — a GC must never key on it\r\n<!-- [doc->REQ-HAZARD-PERCH-GC-LIVENESS-INVERSION] -->\r\n<!-- [doc->REQ-PERCH-GC-RESIDUE-PREDICATE] -->\r\n- **Failure:** the obvious way to write a perch garbage collector is \"reap what is not alive\" — `!spt_store::liveness::is_perch_alive(dir)`. On the population a GC actually walks, that predicate is **backwards**. `is_perch_alive` returns **true** for a directory with no `info.json` (`RawRead::Absent ⇒ true`, interim parity — an absent record means a wrapper-owned listener between polls), and **false** for a daemon-hosted endpoint whose `status` is `offline`. Measured on HFENDULEAM 2026-08-04 across 38 top-level perch dirs: **all 24 recordless residue directories read ALIVE, and all 6 offline REAL endpoints read DEAD.** A sweep keyed on `!is_perch_alive` would have spared every stray probe directory and deleted six resting agents' records — it does not under-perform, it authorizes **exactly the inverse set**.\r\n- **Why it is a hazard and not a bug in the resolver:** `is_perch_alive` is correct for its own job. Fail-toward-alive is the safe direction for DELIVERY (2.5) — the cost of a false \"alive\" is one message taking the spool path. It is the wrong direction for DELETION, where a false \"not alive\" is irreversible. The inversion is what happens when a predicate is reused across a polarity boundary it was never sized for.\r\n- **Invariant:** perch garbage collection classifies on record **presence** only (3.5's predicate: no `info.json` present on any read attempt ⇒ residue; NotFound kept distinct from every other I/O error, because absent is the only answer that authorizes deletion) and **never calls a liveness resolver** — not `is_perch_alive`, not `is_registry_entry_alive`, not a pid probe. The registry is likewise never asked: `clean_stale_entries` deletes dead-pid rows and `unregister_address` fires on an ordinary stop, so registry-absence is the normal steady state of every offline endpoint (4.3). The unit pinning this asserts **both** arms with the shipped resolver as the witness: residue reads alive and is reaped anyway; an offline endpoint reads dead and is kept anyway.\r\n- **spt-core mapping:** `spt_store::perchgc::{sweep, PerchClass}`; `spt endpoint gc` renders it. The refusal/report contract is `REQ-PERCH-GC-REFUSAL-REPORT`; the occupancy rules it inherits are 3.4.\r\n- **Source:** measured by todlando on HFENDULEAM 2026-08-04 while answering doyle's step-1 predicate question on releases#109; ruled into the lane by doyle the same day.\r\n\r\n---\r\n\r\n## 4. Wire / transport\r\n\r\n### 4.1 Envelope HTML-entity codec ordering — `&amp;` decoded LAST\r\n- **Failure:** decoding `&amp;`-entity before the others double-decodes nested entities (`&amp;amp;lt;` → wrong result).\r\n- **Invariant:** ENCODE order amp→first … `<br>`→last; DECODE order `<br>`→first … amp→**last** (`&lt;`,`&gt;`,`&quot;`, then `&amp;`). One sole decode site (at the LLM/stdin boundary); the parser never decodes.\r\n- **spt-core mapping:** `spt-proto` owns the envelope grammar (public SDK, semver + wire-version). This codec contract is a copy-verbatim commodity item (ADR-0001) and a public-API conformance test.\r\n- **Sister cite:** `src/owl/poll.rs:1-73`; `src/common/envelope.rs`.\r\n- **CR-linesafety `[REQ-HAZARD-ENVELOPE-CR-LINESAFE]`:** the EVENT is LINE-FRAMED, so the codec must neutralize raw `\\r` too — `event_body_escape` folds CRLF/lone-CR to `\\n` (→`<br>`) **before** framing. **Failure (field, 2026-06-08):** a cross-node `spt send` from Windows (`echo` → CRLF) carried a raw `\\r` into the single-line envelope; the receiver terminal did a CR→column-0 overwrite (`</EVENT>` clobbered `<EVENT t`). `\\r` was never line-representable here, so normalizing it is robustness, not an ADR-0001 wire divergence (decoder + amp-last untouched). Belt-and-suspenders: `spt send`/`ring` trim stdin like `notify`.\r\n\r\n### 4.2 Two-slice envelope parser is panic-free and tolerant\r\n- **Failure:** malformed envelope (unclosed/misordered/nested tags) panics or drops output.\r\n- **Invariant:** tags case-sensitive, all optional; no tags → whole body to live slot; unclosed → None for that tag; out-of-order → both still extracted; nested unknown tags preserved verbatim; zero `unwrap` on parsed text.\r\n- **spt-core mapping:** `spt-proto` parser; property-test the robustness rules.\r\n- **Sister cite:** `src/common/envelope.rs:64-92`; tests 99-207.\r\n\r\n### 4.3 Registry stale-entry cleanup precedes lookup\r\n- **Failure:** sender resolves a dead process's stale TCP port → delivery to wrong/dead listener.\r\n- **Invariant:** clean stale entries (dead PID) before/at lookup; spool fallback is the safe path on TCP miss.\r\n- **spt-core mapping:** now spans the **subnet registry** (ADR-0003) — eventually-consistent across nodes. Cross-node staleness is expected; resolution policy (local → most-recent → `id@node`) must degrade to spool/relay fallback on stale hits, and never hard-fail on a stale remote entry.\r\n- **Sister cite:** `src/common/registry.rs:62-78`; `src/owl/send.rs`.\r\n\r\n### 4.4 Deferred rows survive poll drain\r\n- **Failure:** poll `drain_all` flushes a deferred (spool-only) message meant for a hook consumer → message lost.\r\n- **Invariant:** deferred rows are never flushed by the event-stream drain; only `drain_non_deferred_*` / `peek_all` touch them.\r\n- **Sister cite:** CHANGELOG v1.11.20; `src/common/spool.rs`. (See also 1.4.)\r\n\r\n### 4.5 Inbox legacy compat must not double-deliver\r\n- **Failure:** message surfaced via both spool (durable) and legacy inbox files → duplicate or racing delivery.\r\n- **Invariant:** spool is the sole read path at poll time; inbox is write-for-compat only and never read.\r\n- **spt-core mapping:** clean-room — likely drop the legacy inbox entirely. If kept for any compat, preserve \"never read at drain time.\"\r\n- **Sister cite:** `src/common/inbox.rs`.\r\n\r\n### 4.6 Addressable-id charset reserves the address delimiters\r\n<!-- [doc->REQ-HAZARD-ID-CHARSET] -->\r\n- **Failure:** a bare endpoint id that contains `:` or `@` (or a path separator / whitespace / control char) makes the canonical qualified address `[subnet:]id[@node]` (ADR-0006 / REQ-INST-10) ambiguous to parse, and lets a name smuggle into a perch directory path. Once permissive ids exist in the wild, tightening later needs a migration.\r\n- **Invariant:** every addressable id/name is validated to `[A-Za-z0-9_-]` + Hiragana/Katakana/CJK only, length `1..=64`, **at every creation seam** (`ready` start, `api bind`, `api listen`, `api worker-start`). `:` and `@` are permanently reserved as address delimiters; reads of existing perches are never re-validated. Enforce now (pre-M3/M4) so no permissive id-data accumulates.\r\n- **spt-core mapping:** `spt_proto::id::validate_endpoint_id`; called at the four creation seams. The existing Psyche (`<parent>-psyche`) / Worker (`<parent>-w<N>`) suffix scheme uses only `-` + alphanumerics, so composite ids validate.\r\n\r\n### 4.7 Concurrent SQLite openers must not fail with \"database is locked\"\r\n<!-- [doc->REQ-HAZARD-REGISTRY-CONCURRENT] -->\r\n- **Failure:** two endpoints on one machine open the same SQLite store at once (e.g. two `ReadyAgent::start` calls registering simultaneously) and one fails outright with `SQLITE_BUSY` / \"database is locked\" → spurious registration/spool failure. Surfaced as a parallel-test flake in `two_agents_exchange_message_tcp_and_spool`, but the bug is real concurrency, not test-only.\r\n- **Invariant:** `busy_timeout` is set **before** any lock-taking statement on every connection. Switching `journal_mode=WAL` takes a brief exclusive lock; with the default 0ms timeout it fails immediately under contention, so the pragma order is load-bearing: `Connection::open` → `busy_timeout` → `journal_mode=WAL` → `CREATE TABLE …`. WAL alone is insufficient (concurrent *writers* still serialize; they must *wait*, not error).\r\n- **spt-core mapping:** `spt_store::registry::open_registry` + `spt_store::spool::open_spool_at`; both set `busy_timeout=5000` first. Any future SQLite store (history Path B, instance registry) must follow the same ordering.\r\n\r\n### 4.8 Registry merge ordered by epoch, never wall-clock (red-team #8)\r\n<!-- [doc->REQ-HAZARD-REGISTRY-EPOCH-LEASE] -->\r\n- **Failure:** the per-subnet registry replicates `endpoint_id → [instances]` eventually-consistently across nodes. Under a partition or clock skew, a lagging node re-announces a stale `Active` for an endpoint that has actually gone `Offline`. If the merge ordered updates by wall-clock (or \"last write wins\"), the stale `Active` overwrites the newer `Offline` and resolution routes a message to a dead/wrong instance.\r\n- **Invariant:** the merge precedence key is a **per-node monotonic epoch counter** (`spt_store::epoch::EpochSource`, persisted, strictly increasing, NEVER wall-clock), compared version-vector style per `(endpoint_id, node)`: an incoming update wins **iff its epoch is strictly greater** than the stored one for that node; equal or lower is dropped as stale. So a newer `Offline` (higher epoch) can never be clobbered by a lagging `Active` (lower epoch), and an idempotent equal-epoch replay is a no-op. Wall-clock is at most a human tiebreaker hint inside a flagged conflict, never the ordering authority. The same epoch source unifies with the D6 sync-precedence concurrent-write detection (#7).\r\n- **spt-core mapping:** `spt_net::net::registry::SubnetRegistry::merge_instance` (the lease) + `spt_store::epoch::EpochSource` (the counter). Cross-node replication of the merge wires at D4; the merge seam is identical for local and wire-delivered updates. Chaos/two-host verification = D9.\r\n\r\n### 4.9 SQLite stores must create their parent dir — SQLite won't\r\n<!-- [doc->REQ-HAZARD-REGISTRY-DIR-CREATE] -->\r\n- **Failure:** `Connection::open` creates the database FILE but never its parent DIRECTORY. On a fresh home (first boot, fresh CI `_work` dir) a registry op that runs before any perch-creating op (`create_dir_all` side effects) fails `SQLITE_CANTOPEN` — \"unable to open database file …owlery\\.registry\". Timing-dependent: whichever code path touches the home first decides the outcome, so it surfaces as a parallel-test flake (bind-first tests losing the dir-creation race to perch-first tests). Bit the hfenduleam CI leg twice (2026-06-03/04, four spt-msg unit tests at once on the second strike) before being run to ground; a slow runner filesystem (AV scanning fresh dirs) widens the window but is not the cause.\r\n- **Invariant:** every SQLite store's open path `create_dir_all`s its parent dir itself, best-effort, before `Connection::open` — never relying on another subsystem having materialized the home first. (Mirrors the spool, which always did this; the registry didn't.)\r\n- **spt-core mapping:** `spt_store::registry::open_registry` (`create_dir_all(owlery)` before open). `spt_store::spool::open_spool_at` already creates its perch dir. Any future SQLite store must do the same — pair this with the 4.7 pragma ordering on every new store.\r\n\r\n### 4.10 Dead node identities leave immortal registry rows  `[REQ-HAZARD-REGISTRY-GHOST-ROWS]`\r\n<!-- [doc->REQ-HAZARD-REGISTRY-GHOST-ROWS] -->\r\n- **Failure:** the registry's only superseding mechanism is the per-`(endpoint_id, node)` epoch lease (4.8) — a row is replaced only by a newer row *from the same node*. When a node identity dies permanently (machine retired, or `node.key` regenerated so the \"node\" never speaks again), its rows are never superseded and never expire: they sit in the in-memory registries and the `identity/registry/<subnet>.json` snapshots forever. A bare-id send then resolves the same endpoint id on both the live and the dead identity and refuses with a **phantom `AcrossNodes` ambiguity** — unfixable by the user, because no qualifier reaches a node that no longer exists. Hit live in the M7 acceptance run (2026-06-06): gravity paired under two identities (09ef…, then 03854a… after its key universe flipped during the sudo experiments); the dead identity's `sergey` row made bare `spt send sergey` refuse on HFENDULEAM.\r\n- **Invariant:** registry rows authored by a **silent** peer node decay: a node not *heard* (admitted inbound feed — the M7 D2 heard-map, REQ-SUBNET-1) within the eviction window (`registry_evict_after_ms`, default 300s ≈ 10 default pump cadences) has its rows **evicted** from every subnet registry, snapshots rewritten. Own rows never decay (the node always hears itself implicitly — it authors them each pump tick). Eviction is safe under the lease: v1 has **no transitive gossip**, so any future update for a node comes from that node itself, alive, re-inserting from its durable `EpochSource` within one cadence — there is no lagging third-party replay to mis-order against. A merely-offline node loses its rows after the window and reconverges on return; meanwhile resolution honestly reports it absent instead of poisoning bare-id sends.\r\n- **spt-core mapping:** `spt_net::net::registry::SubnetRegistry::evict_nodes` (model) + `spt_daemon::registryhost::RegistryHost::evict_silent_peers` (heard-map TTL) driven from the registry pump tick (`peerloop`). Trust rows are NOT auto-evicted (trust is a user decision; a stale trust row only costs dead dials) — pruning those is a separate verb.\r\n- **Source:** M7 acceptance run 2026-06-06 (DEFERRED.md \"Ghost registry row eviction\"); the AMBIGUOUS render fix rode along.\r\n- **Mesh note (ADR-0017, 2026-06-08):** the subnet mesh **preserves** this invariant rather than superseding it. \"No transitive gossip\" sharpens to **no transitive *row* gossip** — the mesh relays only the member *roster* (discovery), while registry **rows stay own-authored and are fetched directly** from each member over a handshake. So \"any future update for a node comes from that node itself, alive\" still holds and the eviction lease is untouched. (The plan's rejected alternative — signed transitive *row* relay — would have broken this; roster-only relay was chosen precisely to keep it.)\r\n\r\n### 4.11 Advertisement-epoch reset strands a node  `[REQ-HAZARD-EPOCH-RESET]`\r\n<!-- [doc->REQ-HAZARD-EPOCH-RESET] -->\r\n- **Failure:** a node whose advertisement-epoch counter resets (the durable `EpochSource` file lost/recreated) re-advertises with LOW epochs; peers hold a higher last-seen epoch for that `(endpoint, node)` lease and drop every fresh row as **stale** — the node advertises into a void until its counter outruns its own history. Nothing renders the cause: the node looks healthy locally, peers simply never update.\r\n- **Invariant (mitigation by construction, common case):** the common trigger — a full reinstall / identity regeneration — is covered by the **re-pair trust overwrite** (M8 decision 13, REQ-SUBNET-7): a completed ceremony presenting the same label + machine id evicts the superseded identity's trust AND registry rows on the seed-holder, and the peer-side epoch memory **dies with the deleted row** — the re-paired node's fresh epochs land on a clean lease. M8 acceptance 7 verifies this explicitly (the epoch sub-check).\r\n- **Residual (documented, guard deferred):** the narrow slice — epoch file lost while the node *identity* is kept (manual state surgery, partial restore from backup) — has no guard; it waits for a field hit before one is designed (M8 decision 24). `REQ-HAZARD-EPOCH-RESET` is minted inactive (TRACEABILITY rule 5) as the tracking hook. If hit: symptoms are one node's endpoints frozen-stale on every peer while its own views are fresh; recovery today is re-pairing the node (rides the common-case eviction above).\r\n- **spt-core mapping:** epoch mint = `spt_store::epoch::EpochSource` (`identity/epoch.json`); the lease = the per-`(endpoint, node)` epoch compare in `spt_net::net::registry`; the eviction that clears peer-side epoch memory = `registryhost::repair_evict_superseded` + `RegistryHost::consume_repair_evictions`.\r\n- **Source:** minted at M8 ratification (decision 24), recognized as a class during the 2026-06-07 pump diagnosis / re-pair overwrite design — not yet field-hit in its residual form.\r\n\r\n---\r\n\r\n## 5. Platform-specific\r\n\r\n### 5.1 Windows PID recycling false positives\r\n- **Failure:** recycled PID reads alive for the wrong process → orphan misclassification.\r\n- **Invariant:** anchor liveness on the stable parent/harness PID; minimal info.json for supervisor-owned perches; mtime grace window (≥60s) masks transient mismatches.\r\n- **spt-core mapping:** broker-held handles supersede PID polling for spt-hosted sessions; keep the grace window for harness-hosted.\r\n- **Sister cite:** `src/live/wrapper/orphan.rs:141-161`; `src/common/list_filter.rs:168-175`.\r\n\r\n### 5.2 Windows EBUSY on atomic rename\r\n- **Failure:** `fs::rename` fails while a handle is (recently) held → registry/marketplace update fails.\r\n- **Invariant:** tmp-write + atomic-rename with retry/backoff; best-effort side-fail; tolerate transient EBUSY.\r\n- **spt-core mapping:** all on-disk state writes (registry, trust store, spool checkpoints) use this pattern.

ConPTY blocks all child stdout until the terminal answers the cursor-position query.\r\n- **Invariant:** every ConPTY reader auto-answers DSR (`ESC [ 6 n` → write `ESC [ 1;1 R`, or a real cursor position) on the PTY writer. Secondary: a ConPTY master does not EOF while the writer is held, so read loops drain on a thread and never gate exit on a blocking `read()`.\r\n- **spt-core mapping:** `spt-term` broker PTY reader (ADR-0004).

That `spt` process detach-spawns a **long-lived** child (the daemon via `ensure_running`; a shell binary via `spt shell spawn`). On Windows `CreateProcess` runs with `bInheritHandles = TRUE`, and the spt process's std handles — the caller's pipe write-ends — are inheritable by construction, so the immortal child inherits them even when its *own* stdio is `Stdio::null()`. The caller's pipe read never sees EOF: the capturing caller **hangs forever** (unix is immune — pipe fds are `CLOEXEC`). Paid twice: daemon spawn (guarded at D4a-era `spawn_detached`), then again at M5-D3e when the mock-shell E2E hung `spt shell spawn` for hours.\r\n- **Invariant:** every detach-spawn of a long-lived child inherits only handles it **enumerates**. The default and overwhelmingly common form of that is `bInheritHandles = FALSE` (`spt-daemon::daemon::detached_no_inherit`) — zero handles flow, whatever the pipe's depth in the ancestry. Stripping `HANDLE_FLAG_INHERIT` from the spawner's *std* handles is NOT sufficient: a grandparent capture's pipe sits in the handle table as a stray inheritable handle and still flows through every **bare** `bInheritHandles = TRUE` hop (the first guard shipped that way and was wedged by exactly this — a daemon spawned three layers deep held the pwsh-level pipe of the CI/test harness).\r\n- **The one permitted TRUE (amended 2026-07-26, RESIDENT-SERVICE W1):** a spawn that must capture the child's output may pass `bInheritHandles = TRUE` **only** paired with an explicit `STARTUPINFOEX` + `PROC_THREAD_ATTRIBUTE_HANDLE_LIST` allowlist — the Win32 contract honors the list only under TRUE, so the earlier phrasing (\"flipping TRUE is refused\") forbade its own mechanism and was unimplementable. The hazard was always *unenumerated* inheritance, and the list **is** the enumeration: only the named handles flow, so a grandparent's pipe cannot reach the child at any depth — strictly stronger than what FALSE achieves incidentally. A **bare** TRUE, with no attribute list, remains REFUSED. Today the only such path is a supervised `[service]` spawn with startup capture (one-entry list, one file handle), and it is pinned behaviorally, not by flag-reading: `a_captured_spawn_inherits_only_the_handle_in_its_allowlist` plants a deliberately inheritable handle that is NOT in the list and fails if the child receives it.\r\n- **spt-core mapping:** `spt-daemon::daemon::spawn_detached` (the daemon) and `spt-daemon::shellhost::launch_shell` (the relay-receipt shell binary). Any future long-lived detached spawn (manifest-template children included) must use the same no-inherit spawn, or the enumerated form above where it genuinely must capture output.\r\n- **Source:** spt-core, M5-D3e (`shell_e2e.rs` hang, 2026-06-04, twice — once per guard generation); Rust `Command` restricts *its own* created stdio handles but a parent's inheritable handle table still flows.\r\n\r\n### 5.7 Elevated commands spawn the daemon with the wrong token  `[REQ-HAZARD-ELEVATED-DAEMON-SPAWN]`\r\n<!-- [doc->REQ-HAZARD-ELEVATED-DAEMON-SPAWN] -->\r\n- **Failure:** membership-implies-reachability made *every* `spt` invocation a potential daemon spawner (`ensure_running`), including the elevation-gated ones (`subnet create`/`join`, REQ-SUBNET-4). The spawned daemon inherits the spawner's token. **Windows:** an elevated `subnet create` auto-starts an ELEVATED daemon whose named pipes deny unelevated clients — every subsequent unelevated `spt` reads \"not running\", tries to spawn its own daemon, and dies on bind Access-denied; the user had to taskkill (hit live, M7 acceptance 2026-06-06). **Linux:** a sudo'd command spawns a root daemon and/or root-owned state — and because sudo flips `$HOME`, the daemon can mint a *different node identity* in root's universe (the very key-flip that produced the 4.10 ghost rows).\r\n- **Invariant:** the daemon **always runs unelevated in the invoking user's universe**, regardless of which command spawns it. Two enforcement points sharing one seam: (a) `spawn_detached` de-elevates the child — Windows: the UAC **linked token** (`TokenLinkedToken` → `DuplicateTokenEx` → `CreateProcessWithTokenW`; inherits no handles, so 5.6 holds by construction); Linux: drop to `SUDO_UID`/`SUDO_GID` with `$HOME`/`$USER`/`$LOGNAME` reset to the invoking user's (passwd lookup); (b) a `Daemon::run` entry guard catches a *directly* elevated `spt daemon` — Linux drops privileges in-process before touching any state; Windows respawns de-elevated and exits. When no unelevated identity exists to drop to (UAC disabled, genuine root login, SYSTEM), the daemon runs as-is with a loud warning — a consistent universe, never a torn one. Elevated one-shot *clients* talking to an unelevated daemon are fine (downward connects work); the daemon side is the invariant.\r\n- **spt-core mapping:** `spt-daemon::deelevate` (the OS-split seam) consumed by `daemon::spawn_detached` + the `Daemon::run` entry guard. The fuller Linux elevation model (install symlink + default-account election) is deferred (DEFERRED.md, M8).\r\n- **Source:** M7 acceptance run 2026-06-06 (DEFERRED.md \"Non-admin daemon spawn\"); interim field rule was \"bring the daemon up unelevated FIRST\".\r\n\r\n<!-- [doc->REQ-HAZARD-CHILD-CONSOLE-FLASH] -->\r\n### 5.8 Console children of the console-less daemon flash visible windows  `[REQ-HAZARD-CHILD-CONSOLE-FLASH]`\r\n- **Failure:** the daemon runs DETACHED (no console, 5.6/`detached_no_inherit`). Any console-subsystem child it spawns (`git`, `taskkill`, manifest hook commands) gets a **fresh conhost with a visible window** — piped/null stdio does NOT prevent it. Field shape: the 60s sync pump's two git calls (`for-each-ref` + `rev-parse`) flashed two blank windows per minute on the user's desktop (2026-06-06).\r\n- **Invariant:** every short-lived console child spawned from daemon-reachable code sets `creation_flags(0x0800_0000)` (`CREATE_NO_WINDOW`). Long-lived detached children use `detached_no_inherit` (already `DETACHED_PROCESS | CREATE_NO_WINDOW`); de-elevated spawns use `CREATE_NEW_CONSOLE + SW_HIDE` (5.7 — `CreateProcessWithTokenW` rejects `CREATE_NO_WINDOW`, error 87).\r\n- **Test seam caveat:** window-absence is unobservable from a consoled test runner — the child inherits the runner's console and never creates a window, flag or no flag. Unit coverage asserts the flagged spawn still works (the error-87 \"flag combo breaks spawn\" regression class); window-absence was verified live by process-watch capture.\r\n- **spt-core mapping:** `spt-store::gitrun::run_git` (every BranchStore/ContextStore git call), `spt-daemon::shellhost::kill_shell_pid` (taskkill), `spt-runtime::run_bounded_command` (manifest hook commands), `spt-runtime::ManifestRuntime::command_for` (the one shared builder behind `spawn_session` + `run_bounded_stdin` — the notif pump's `spawn_notif_command` and the live agent's psyche/echo/turn spawns), `spt-daemon::shellwake` (already guarded). The flag lives in each shared builder, not per call site, so the invariant holds for every ManifestRuntime spawn by construction.\r\n- **Source:** spt-core field bug, 2026-06-06 — two blank windows flashing every 60 seconds on a desktop workstation, caught by process-spawn watcher (git.exe parent=spt daemon, conhost.exe child each).\r\n\r\n### 5.9 `Instant - Duration` underflow-panics on a freshly-booted host  `[REQ-HAZARD-INSTANT-UNDERFLOW]`\r\n- **Failure:** `Instant::now() - Duration::from_secs(N)` panics `overflow when subtracting duration from instant` when the process's monotonic clock is younger than `N` — i.e. the host booted less than `N` ago. The peer pump primed its cadence legs with `Instant::now() - 86_400s` to mean \"everything due now\"; on a Windows runner with sub-24h uptime the pump thread panicked at startup, so the subnet never converged (CI `pump_and_dispatch_self_drive_the_subnet` failed, run 27082417706). It is *environment-conditional* — green on any host up longer than the offset, red below it — so it slips local dev and only bites a fresh CI box or a just-rebooted machine.\r\n- **Invariant:** NEVER compute an instant in the past by subtracting from `Instant::now()`. Represent \"never run / due now\" as `Option<Instant> = None` and gate on forward `now.duration_since(past)` only (`peerloop::due`). No backward instant arithmetic anywhere in scheduling.\r\n- **Test seam caveat:** the convergence E2E only reproduces on a sub-offset-uptime host (it passed everywhere with >24h uptime). The deterministic guard is the `due(None, ..)`/`due(Some(now), ..)` unit on the extracted gate — it asserts first-tick-due with zero instant subtraction, independent of host uptime.\r\n- **spt-core mapping:** `spt-daemon::peerloop::due` (the sole cadence gate behind `due_reg`/`due_notif`/`due_sync`/`due_upd`); cadence legs are `Option<Instant>` seeded `None`.\r\n- **Source:** spt-core CI failure, 2026-06-07 — Windows runner `hfenduleam` (just booted) panicked the peer pump at the v0.1.1 release gate.\r\n\r\n### 5.10 `sudo spt` dead-ends on a user-local install (secure_path)  `[REQ-HAZARD-SUDO-SECURE-PATH]`\r\n- **Failure:** the elevation-gated commands (`subnet create` / `subnet join` / `show-code`) refuse when unelevated and tell the user to \"run as administrator / root\". The user types the obvious `sudo spt subnet create FOO` → `sudo: spt: command not found`. `spt` is a user-local install (`~/.local/bin`, `~/.cargo/bin`), and sudo's `secure_path` (a `/etc/sudoers` default) does NOT include those dirs, so a bare command name doesn't resolve under sudo. The guidance is a trap: it names an action that cannot work for the common install shape. Field-hit on KITSUBITO at the v0.1.1 ship.\r\n- **Invariant:** elevation guidance on Unix emits the binary's **absolute path** under sudo — `sudo /home/u/.local/bin/spt subnet create FOO` — reconstructed from `current_exe()` + the real argv and shell-quoted. An absolute program path is executed directly; `secure_path` only governs bare-name PATH lookup, so the absolute form always resolves. On an interactive Unix TTY the command auto-elevates (re-execs itself under sudo, the elevated child does the work and `main` de-elevates back); non-interactive or sudo-absent falls back to printing the runnable hint. Never emit a bare-name elevation instruction.\r\n- **Companion UX:** the post-de-elevation `DEELEVATED: running as uid N` line is internal state-safety noise — omit it from the user-facing CLI path (it confused the same field user). The detached daemon's own de-elevation log line is fine (it lands in the daemon log, not the terminal).\r\n- **Test seam caveat:** the sudo re-exec needs a real `sudo` + TTY (not hermetic). The deterministic guard is the pure `elevation::sudo_argv` / `print_hint_command` (assert an absolute exe path, never a bare name, + shell-quoting on the printed line) and the `decide_elevation_path` matrix (which picks inline-sudo only on an interactive Unix TTY); the exec leg is manual/kitsubito-verified.\r\n- **spt-core mapping:** `spt::elevation::{sudo_argv, print_hint_command, decide_elevation_path}` (pure — generalized from the M12-W4 self-elevation seam, 5.11), `spt::cli::{try_auto_elevate, with_elevation_hint}` wired into `cmd_subnet_create` / `cmd_subnet_join` / `cmd_subnet_show_code`; `spt::main` de-elevation drop silenced.\r\n- **Source:** spt-core field report, 2026-06-07 — `reavus@KITSUBITO`, `spt` in `~/.local/bin`; the absolute-path `sudo` invocation was confirmed working before the fix landed.\r\n\r\n### 5.11 Self-elevating re-launch must re-run verbatim, never widen / inject / loop  `[REQ-HAZARD-SELF-ELEVATE]`\r\n- **Failure class:** a privilege-gated command (`subnet create` / `join` / `show-code`) self-elevates by re-launching itself with privilege (Windows UAC `runas`, Linux `pkexec` / a terminal-emulator `sudo`, or inline `sudo`). A careless re-launch is a security hole: widening the privilege scope (adding args), resolving the binary by a bare name (a PATH/`secure_path` hijack runs an attacker's `spt`), interpolating a crafted arg into a shell string (`sh -c \"… $id …\"` injects a second command), or re-elevating the already-elevated child (an infinite UAC/polkit loop). The user's UAC/polkit/sudo prompt is the ONLY consent gate — the mechanism must never bypass or widen it.\r\n- **Invariant:** self-elevation re-runs the **EXACT** original invocation with the binary's **ABSOLUTE** exe path — never adding/altering args, never a PATH-resolved bare name, never a shell-interpolated string. Every launcher passes an **argv array** (`Command::new(prog).args([...])`, never `sh -c`); the Windows `ShellExecuteW` params string (which is inherently one string) MSVC-quotes each verbatim arg so `CommandLineToArgvW` round-trips it as a single token. The elevated child drops state back to the user (composes with the 5.7 de-elevation) and **never re-elevates**: `decide_elevation_path` returns `AlreadyElevated` whenever the process is `Elevated`, on every OS (loop-safety). The unprivileged parent never pipes/captures the elevated child's stdout across the privilege boundary — the child is self-contained (on Windows it self-pauses a fresh console via `GetConsoleProcessList` so its output stays legible). The print-hint floor prints the absolute-path command too.\r\n- **Test seam caveat:** the real launch needs a UAC/polkit/sudo prompt (not hermetic) — manual-verify. The deterministic guards are the pure `decide_elevation_path` matrix (loop-safety: `AlreadyElevated` on every os; the os×env path order) and the argv builders (`sudo_argv` / `pkexec_argv` / `terminal_argv` assert absolute-exe + verbatim args + array; `windows_runas_params` asserts MSVC-quoting with no `cmd /c` interpolation; the crafted-arg test asserts a shell-metachar arg stays one element / one quoted token).\r\n- **spt-core mapping:** `spt::elevation::{decide_elevation_path, sudo_argv, pkexec_argv, terminal_argv, windows_runas_params, print_hint_command, ElevatePath}` (pure), `spt::cli::{try_auto_elevate, launch_uac_window, pause_elevated_console_if_fresh, program_on_path, first_terminal_emulator}` (impure launchers) wired into `cmd_subnet_create` / `cmd_subnet_join` / `cmd_subnet_show_code`.

A node/npm CLI installs as BOTH an extensionless shebang shim (`ccs`, for Git Bash) and a Windows launcher (`ccs.cmd`) in the same dir; portable-pty picks the extensionless `ccs`, and `CreateProcessW` then tries to execute that non-PE file and fails with **os error 193** (\"%1 is not a valid Win32 application\"). Live failure: `spt endpoint run claude-spt:ccs` → `CreateProcessW C:\\nvm4w\\nodejs\\ccs` 193 (operator, 2026-06-16). The same bites any harness/shell whose `[session.self]`/`[shell].spawn` names a `.cmd`/`.bat`/`.ps1`-backed command — `CreateProcessW` cannot execute a batch or PowerShell script directly.\r\n- **Invariant:** spt-term resolves the program ITSELF before handing it to `CommandBuilder`, bypassing portable-pty's `which`. A bare name is searched over `PATH` × `PATHEXT` (whose default order already prefers `.EXE`/`.COM` over `.BAT`/`.CMD`), then an extensionless fallback. A non-PE target is wrapped in its interpreter: `.cmd`/`.bat` → `cmd.exe /d /c <path>`, `.ps1` → `powershell -NoProfile -File <path>` (the wrap args precede the caller's args); a real executable spawns directly; an unresolvable name passes through unchanged (never makes a working case worse). Unix is a passthrough — `execve` honours a shebang on an extensionless script. Applied at the ONE `CommandBuilder` chokepoint (`PtySession::spawn_program_in`), so every broker harness + shell spawn is covered. *Caveat:* the `cmd.exe /d /c` wrap inherits cmd's argument-quoting rules for paths/args containing spaces or cmd metacharacters — adequate for the common install-path case; a fully robust cmd-quoting pass is a follow-on if it bites.\r\n- **spt-core mapping:** `spt_term::winprog::{resolve_for_pty, resolve_in}` (the pure PATHEXT-precedence kernel + the Windows env wiring), wired into `spt_term::pty::PtySession::spawn_program_in`.

The rename's directory **metadata** is journaled durable, but the tmp file's **data blocks** are still in the page cache. A hard reset (power loss, forced reboot) between the two flushes lands the rename but loses the data → the file reappears at its **full length filled with NUL**. Field incident: after a machine restart `owlery/hall-a/info.json` was 360 bytes of all-NUL (the nested psyche record 125 bytes all-NUL); `Get-Content` renders blank, `Format-Hex` shows the zero-fill. A wiped-but-present record then read as a live ONLINE endpoint for days (compounded by 5.14).\r\n- **Invariant:** for records whose loss is **unrecoverable**, flush data to stable storage **before** the rename publishes the name — `File::create(tmp)` → `write_all` → `sync_all()` → `rename_with_retry`. Then a crash yields the complete old file OR the complete new file, never a NUL husk. (A file of correct length that is ALL-NUL is the diagnostic tell of this class — a non-fsync'd write caught by a hard reset.) **Durability is SCOPED, not blanket.** `fsync`ing *every* atomic write serializes a durable flush behind each of the ~26 `atomic_write` callers — and for `info.json` the flush lands under the per-perch `.info.lock` (the **W1b lock-across-fsync wedge shape**, §6-era) — which stalls daemon bringup 4–6× so the endpoint misses its ONLINE window. Scope the fsync to the record, not the writer: only authoritative per-perch records and one-shot identity material are durable; reconstructible state (registry snapshots, epoch counters, peer caches, the release cache) stays non-durable — a post-crash NUL husk parse-fails to *absent* and is regenerated / re-gossiped, and the 5.14 read-side already makes a corrupt record harmless at every seam.\r\n- **spt-core mapping:** `spt_store::atomic::atomic_write_bytes_durable` / `atomic_write_string_durable` are the opt-in durable siblings; the default `atomic_write_bytes` / `atomic_write_string` stay non-durable. Durable callers are exactly `spt_store::info::write_info` (the perch record — the hall-a surface), `spt_store::nodeid` (the node seed — corrupt is node-bricking, never regenerated), and `spt_daemon::machineid` (minted-once machine id — a NUL husk would silently re-mint a different id). Reader-side handling of an already-corrupt record is the sibling 5.14. **Canary:** `attach_wedge_e2e` is the regression guard — a blanket fsync fails it (bringup misses the 20s ONLINE budget); keep durability scoped so it stays green.\r\n- **Source:** field diagnosis 2026-07-01 (operator, post-v0.19.0 restart) — counter-39 bug #2; blanket-fsync perf regression pinned + scoped by the gate rig (doyle), same date.\r\n\r\n<!-- [doc->REQ-HAZARD-CORRUPT-PERCH-COHERENCE] -->\r\n### 5.14 Corrupt info.json read as ABSENT → fail-open readers gossip a wiped perch ONLINE  `[REQ-HAZARD-CORRUPT-PERCH-COHERENCE]`\r\n- **Failure:** three readers each collapsed a **corrupt** (present-but-unparseable) `info.json` into their fail-open ABSENT default, so a NUL-wiped perch (5.13) read as permanently live: `is_perch_alive` returned `true` (unreadable ⇒ interim-alive), `advertised_status` then saw alive + no resting record ⇒ `Active`, and the daemon self-gossiped that Active row every round (epoch 173k+). Result: `hall-a`, dead since a machine restart, showed ONLINE in `spt whoami` and on every remote picker.\r\n- **Invariant:** CORRUPT ≠ ABSENT. A record that EXISTS but stays unparseable across the retry budget is a **destroyed** record — never a live endpoint. `is_perch_alive` reads corrupt ⇒ **not alive** (ABSENT keeps interim-alive parity — the ONE case that stays true); `advertised_status` then lands corrupt in the cold arm ⇒ **Suspended**, never Active/Dormant.

Two processes writing the SAME target concurrently — traced at bind ~700µs apart: the daemon's `mutate_info` RMW and `spt api bind`'s `establish_perch` — both create the same `info.json.tmp`; whichever renames first CONSUMES it, and the loser's `fs::rename` hits `NotFound` (os error 2). `NotFound` is non-transient in `rename_with_retry`, so it surfaces as a hard write error: `establish_perch` returns `BindError::Io` *after* having written the record, mock-session's bind-is-fatal check `exit(1)`s, the harness dies, and the endpoint never reaches ONLINE. A microsecond window that existed forever (bare `fs::write` + rename back-to-back) — the 5.13 `sync_all` widened create→rename ~50× (to ~4ms) and made the collision near-certain *exactly at bind*, which is why the durable-perch-record change unmasked it (deterministic wedge, not a perf regression).\r\n- **Invariant:** concurrent atomic writers to the same target must never share a tmp name. Stage a **unique** tmp per write — `{name}.tmp.{pid}-{seq}`, `seq` from a process-local static `AtomicU64` (no clock, no rand → resume/replay-safe) — on BOTH the durable and non-durable paths (the collision is generic to `atomic_write`, not the fsync).

At bind the two writers race (~700µs apart): the daemon RMW reads the PRE-BIND record, bind's `write_info` renames the full record in (`state=live_agent`, `controllable=Some(true)`, `session_id`), then the RMW writes its STALE pre-bind snapshot back plus a `status=online` stamp. The surviving `info.json` is a **pre-bind shape carrying `status=online`** — bringup passes (it sees ONLINE), the broker serves the session, then on child death `reconcile_hosted_liveness` reads `state != \"live_agent\"` (or `controllable != Some(true)`) and *silently `continue`s* — the dead endpoint is latched ONLINE forever. This resurrects counter-39 #2's dead-but-ONLINE field surface through a brand-new path. Once-loud, now-silent: 5.15's unique tmp turned the previously-`os-error-2` collision into a clean last-writer-wins, and the 5.13 durable fsync (inside the RMW read→write window) made the interleave near-certain on a normal-speed disk. The race predates all of this (v0.19.0-era) — the old fixed tmp made it fail LOUD and non-durable kept the window µs-narrow.\r\n- **Invariant:** every `info.json` writer serializes under the one per-perch `.info.lock`. A whole-record write (`write_info`) takes the lock exactly as the RMW (`mutate_info`) does — a unique tmp only makes concurrent writes *last-writer-wins*, which is safe ONLY if the writers are serialized (cross-ref 5.15). A multi-step read→check→write (bind's establish) must hold ONE lock acquisition across all three (a true compare-and-set) — check-then-write with the lock dropped in between still interleaves a stamp. Readers stay lock-free (the atomic rename already gives a complete old-or-new record). Holding `.info.lock` across the durable fsync is ms-scale on these infrequent record writes (the same thing every `mutate_info` already does), NOT the per-keystroke W1b lock-across-fsync shape.\r\n- **spt-core mapping:** `spt_store::info` — `write_info` now acquires the sentinel then calls a private `write_info_unlocked` (and `mutate_info` — the public RMW primitive — calls the unlocked writer while holding its own lock, so no double-lock deadlock); `info::establish_locked(perch, build)` runs the bind's read→check→build→write as one locked CAS, called by `spt::api::startup::establish_perch`. The other read-modify-write callers were audited and the two that mutate a load-bearing field were converted to the `mutate_info` CAS: `spt::api::reporting::cmd_boundary` (rc-rebind session-id rotation) and `spt_store::home::adopt_for_unset` (home-subnet adoption; the `is_none()` re-check runs inside the closure). **Deliberately parked (known unlocked-RMW residue, honest coverage):** `spt_msg::listener::write_busy` (BUSY-pid stamp — self-healing: re-marked next delivery, recency next tick) and `spt_store::rename::rewrite_id` (rare operator rename ripple) still do a raw read→write; a lost update there self-heals or is operationally rare, so they are left as follow-ups. `spt_msg::ready::start_homed` (harness-hosted `ready`/`listen` bind) is the same read→build→write *shape* as `establish_perch` but is a single-writer context (the daemon does not host/stamp a harness-hosted ready agent concurrently at its own bind), so it is left as-is — revisit if a daemon-hosted path ever stamps it. Regression guard: `write_info_racing_mutate_info_never_lost_update` — a `Barrier`-aligned RMW-stamp vs full-bind-record write hammer on one perch asserting the full record's fields never vanish under a racing stamp (reds on the unlocked-write code, greens after the lock).\r\n- **Source:** RCA 2026-07-01 (doyle gate rig) — differential (baseline PASS / 77beeac+baseline-atomic PASS / fe385f5 2/3 FAIL) isolated the atomic rework as the delta; `reconcile_hosted_liveness` emitting ZERO `LIVENESS_RECONCILE_OFFLINE` lines for the dead victim over 20s pinned the silent-skip.

No error, no output, exit status unremarkable: the rig reads as \"my code did not do the thing\" when in fact the *fixture* never ran. Measured 2026-07-26 while building the `[service]` supervision gates: three consecutive runs burned on a fixture that could not have worked, each one re-diagnosed as a supervisor bug. `cmd /c` and `sh -c` run fine under the identical spawn, so the no-op is specific to the shell, not to the detachment.\r\n- **Invariant (rig discipline, not product code):** spawn-based fixtures use `cmd` on Windows and `sh` on unix — never `powershell`. And find a spawned process's descendants **by parentage** via `spt_store::proc::process_table()` (which returns `(pid, ppid)`), never by asking the child to report them: a grandchild that must cooperate to be found is a rig that cannot observe an *uncooperative* one, which is the case the gate exists for.\r\n- **spt-core mapping:** every spawn rig under `crates/spt-daemon` — `servicehost.rs` (`long_running`/`instant_exit`/`noisy_instant_exit` fixtures, the tree-teardown gate) and any future rig over `daemon::detached_no_inherit_env`. No `REQ-HAZARD-*` id and no regression test **deliberately**: the invariant constrains how tests are written, and the only assertion available would be \"the OS still refuses to run powershell this way\" — an instrument test, which is never requirement evidence. It is numbered here because the cost is paid by whoever writes the *next* rig, and a fact that reads as a bug in your own code is exactly what this document exists to intercept.\r\n- **Source:** RESIDENT-SERVICE W1 leg D (todlando, 2026-07-26); ruled into this document by doyle the same day.\r\n- **Amendment 2026-08-02 (hertz, releases#110 measurement):** the cause is `DETACHED_PROCESS` **alone** — not the no-inherit half, as the entry's parenthetical implied. Measured on HFENDULEAM with raw `creationflags` and fully piped stdio: `powershell -Command \"Set-Content …\"` under `DETACHED_PROCESS` exits **rc=0 having written no file** (it does not execute); under `CREATE_NO_WINDOW` the identical spawn writes the file and returns its stdout. `cmd /c` behaves DIFFERENTLY from powershell and the entry's \"runs fine\" is half-right: `cmd /c echo ran> file` under `DETACHED_PROCESS` **does execute** (file written, rc=0), but a `cmd /c ping` whose stdout is a pipe returns **zero bytes** — cmd runs and its piped stdout is lost. So the rig rule stands, with the sharper statement of it: under `DETACHED_PROCESS`, powershell does not run at all and cmd's **captured output** cannot be trusted. A rig that parses a detached shell's stdout is reading a value that no longer exists — see 5.18 for the concrete false-green this shape would have manufactured.\r\n\r\n<!-- [doc->REQ-HAZARD-TREE-CWD-PIN] -->\r\n### 5.18 A surviving test descendant cwd-pins the tree it ran in — the `.worktrees` skeleton that will not delete  `[REQ-HAZARD-TREE-CWD-PIN]`\r\n- **Failure:** a directory that is some live process's **current directory** cannot be renamed or deleted on Windows, while files *inside* it stay writable. That asymmetry is why the symptom never reads as a file lock: `git worktree remove` fails naming the **directory**, `openfiles` shows nothing, and the tree looks idle. cargo runs each test binary with cwd = the **package root**, so every child a test spawns inherits `<worktree>/crates/<pkg>` as its own cwd — and any child (or **grandchild**) that outlives the test pins that path forever. Result: a silent `.worktrees` skeleton accumulator, each one costing the next agent an afternoon.\r\n- **Mechanism — the common case is a surviving descendant, and it is not the `CREATE_NO_WINDOW` conhost.** releases#110 filed the holder as an *orphaned `conhost.exe` holding the crate root*; measurement on HFENDULEAM 2026-08-02 **refutes** that for the population the rigs mint. `CREATE_NO_WINDOW` does produce exactly **one conhost per console child** (counted by `ParentProcessId`), but that conhost's cwd is **not** inherited: it is launched with a system cwd. Census: **43 readable, all of them `C:\\WINDOWS\\` or `C:\\WINDOWS\\system32\\`, zero under any worktree** (4 unopenable, stated). Held directly: spawning a child with cwd = the package root and then force-killing it leaves the orphan conhost still reading `C:\\WINDOWS\\`. Positive control on a scratch dir — write-inside **OK**, delete **BLOCKED**, kill the **conhost** → still BLOCKED, kill the actual holder → **deletes first try**. The holder in that control turned out to be an orphaned **grandchild** (`PING.exe`, cwd inherited through `cmd`) that survived its parent's kill. **That conhost is a byproduct, never the pin; killing it is not the cure and \"no conhosts\" is not the all-clear.**\r\n- **Amendment 2026-08-02 — the exception, field-refuted before it shipped: a `--headless` ConPTY conhost DOES inherit its creator's cwd, and pins it alone.** The entry previously generalized the census above into \"a conhost's cwd is never inherited\". That is true of the `CREATE_NO_WINDOW` population and false of the ConPTY one, which no rig mints but every terminal-hosting path does.\r\n  - **Field specimen (BAROMETER W4 teardown):** `pid 46556 conhost.exe --headless --width 80 --height 24 --signal 0x214 --server 0x20c`, born during the build, parent dead, PEB cwd `…\\.worktrees\\barometer-w4\\crates\\spt\\` — the **sole** holder. Killing it deleted the tree that had refused to delete.\r\n  - **Reproduced deliberately, both launch paths.** Minted through `CreatePseudoConsole` from a process whose cwd was a scratch dir: the new `--headless` conhost's PEB reads **that dir**, and with it alive — write-inside **OK**, delete **BLOCKED**, then **DELETED** after `ClosePseudoConsole`, nothing else changed. Launched as `conhost.exe --headless` directly with a working directory: same inheritance. The first covers the path the wild specimen took; the second shows the binary takes its launcher's cwd in that mode regardless.\r\n  - **The pty-teardown alternative is excluded causally, not by absence.** \"Zero children\" clears nothing here — a ConPTY client is a child of whoever called `CreatePseudoConsole`, never of the conhost — so killing the conhost could in principle have taken a living client with it. Kill-**order** rig, client deliberately `cd`'d elsewhere so it cannot be the holder: both alive → **BLOCKED**; kill the **client** only → still **BLOCKED**; kill the **conhost** → **deleted**.\r\n  - **A census of live `--headless` conhosts cannot settle this in either direction.** All 8 alive that day read `C:\\WINDOWS\\system32\\` — and their single creator's cwd *is* `C:\\WINDOWS\\system32\\`, so the value inheritance predicts equals the value OS-assignment predicts, on rows uniform in the asserted property. It reads as confirmation of the old claim and carries no information; the deliberate launch is what discriminates.\r\n  - **Elevation is not the discriminator, and neither reader needs it.** Both readers open with `PROCESS_QUERY_INFORMATION | PROCESS_VM_READ` only and, **unelevated**, read ~46–49 of the ~50 conhosts alive. A first pass that reported *no* conhost readable was a parsing fault in the caller, not an access denial — worth stating because \"not readable\" and \"read as `C:\\WINDOWS\\`\" are the same blank row to a careless reader.\r\n  - **Scoped conclusion:** a `CREATE_NO_WINDOW` conhost is never the pin and killing it is never the cure; a `--headless` ConPTY conhost **can be the sole pin**, and there killing it **is** the cure. Neither sentence licenses the other.\r\n- **Triage step — the finder answers WHO pins, never whether it is SAFE TO KILL.** These are different questions and the blocked-delete error is **identical** for both, which is exactly what makes the step worth writing down. Read the holder's identity *before* acting: an **orphaned descendant** (parent dead, no window, no client) → kill it; a **LIVE process — above all an agent's own shell** → `cd` out, never kill. **When the holder is a `conhost.exe`, its COMMAND LINE is the discriminator** — a bare `conhost.exe 0x…` is the `CREATE_NO_WINDOW` byproduct and is never the pin (look behind it for the descendant), while `conhost.exe --headless --width … --server …` is a ConPTY host that can be the pin itself and dies to a kill. Do not read its **child count** as evidence either way: a ConPTY's client is a child of the pseudoconsole's creator, not of the conhost, so \"zero children\" says nothing about what is alive behind it. Live confirmation 2026-08-02: after one worktree cleared, an identical error on a second traced to a working agent's **own pwsh tool shell**, and behind it that agent's **Bash tool** cwd in the same tree (the two hold *separate* cwds, so clearing one leaves the other). Pattern-matching the kill recipe there would have cost a working agent their session. The pin also follows whatever crate the test ran under, not a fixed package.\r\n- **spt-core mapping:** `.github/ci/find-cwd-holders.ps1` — read-only (`PROCESS_QUERY_INFORMATION | PROCESS_VM_READ`, `NtQueryInformationProcess` → PEB → `RTL_USER_PROCESS_PARAMETERS.CurrentDirectory`), no process opened for write or killed; `-Match <substring>` filters by cwd. It reports its **denominator** (readable vs not-openable) because \"0 rows\" from a filter and \"0 rows\" because nothing could be opened are the same output and very different facts — an empty result means \"no pin I could see\", never \"no pin\". `handle.exe` is not on the box by default and does not distinguish a cwd pin from an open handle; `openfiles` cannot see this at all without the reboot-time maintain-objects-list flag. The **prevention** side is teardown completeness — a rig that reaps its own descendants leaves nothing to pin — which is the `REQ-TEST-RIG-DAEMON-TEARDOWN-PROVEN` (#99) class extended to grandchildren, measured by surviving-process count on both arms rather than asserted.\r\n- **Do NOT \"fix\" this with the spawn flag.** Flipping the rigs' `CommandNoWindowExt::no_window()` (`crates/spt/tests/common/mod.rs`) from `CREATE_NO_WINDOW` to `DETACHED_PROCESS` removes the conhost (measured: 1 → 0) but does **not** remove the pin (that conhost is never the holder — the `--headless` ConPTY exception above is a host no rig mints through this helper), and it breaks rigs outright per the 5.17 amendment: `job_escape_e2e::conhost_children_of` shells out to **powershell** through that very helper and falls back to `unwrap_or(0)`, so a detached spawn would make `wmi_daemon_run_has_no_conhost_window` — the guard for `REQ-HAZARD-WMI-DAEMON-WINDOW` — assert \"no conhost\" **vacuously green**, a gate whose failure signature is identical to the fault it guards. Nor can the helper simply hand children a neutral cwd: `bind_cwd_project_e2e` and `resume_template_e2e` deliberately assert on the **inherited** cwd, which is the behavior under test.\r\n- **Source:** hertz, releases#110 — filed diagnosis post-v0.51.0 (2026-08-01); mechanism re-measured and the conhost attribution **refuted** 2026-08-02 (per-parent conhost counts, box-wide conhost cwd census, orphan-grandchild positive control). doyle's live correction the same day supplied the live-shell half of the triage step. **The `--headless` exception is field evidence from todlando** (BAROMETER W4 teardown specimen, the direct-launch inheritance test, and the kill-order rig that excluded pty teardown), reproduced through the `CreatePseudoConsole` path with a delete-blocked/deleted control by hertz, and ruled an in-milestone amend by doyle the same day — the entry was refuted **before** it shipped in a golden run.\r\n\r\n<!-- [doc->REQ-TEST-ENV-ONE-LOCK] -->\r\n### 5.19 Two mutexes over one process-global env var guard nothing between them  `[REQ-TEST-ENV-ONE-LOCK]`\r\n- **Failure:** two test-helper crates each declare their own `static ENV_LOCK` over the SAME process-global variable (`SPT_HOME`). Each serializes its own callers **flawlessly** — which is exactly what makes the arrangement read as correct — and neither serializes helper A against helper B. Whichever writes last wins. Because `spt_store::perch::spt_home()` is **not memoized** (it re-reads the env on every call), a test writes its fixture into home A and reads it back from home B: the store is absent, an empty access baseline is minted over it, and the assertion fails on a policy that was never loaded. Field shape (releases#111): `cargo test -p spt-daemon --lib dispatch::` lost **1–3 of 26 nondeterministically**, `an_unadmitted_asker_is_refused_at_this_nodes_own_seam` reading `Some(offline)` where the rules should have answered `None`.\r\n- **Invariant (rig discipline, like 5.17):** one variable, one lock, **per binary**. A crate may keep its own ergonomic wrapper (`with_home`, `isolated_home`, a `TestHome` guard) but must **never** keep its own mutex over a variable another helper in the same binary also writes. `spt_test_support::env_lock()` is THE lease; crate-local helpers return that guard. It is **not reentrant** — a `TestHome` holds it for its whole lifetime, so one is never constructed inside a body already holding the lease.\r\n- **Why it hides, and where it does not:** invisible under **nextest** (per-test processes) and invisible when a loser is run **alone** (no concurrent holder), so CI's nextest unit lane is structurally blind to it — the cost falls entirely on whoever hand-runs the module during a gate. This is the same \"invisible-by-construction\" property as 5.17, and the reason it is numbered here rather than left to the requirement.\r\n- **The diagnostic that shortcuts it:** the tell is a **path shape the suspected helper could not have produced**. #111's panic printed `<tmp>\\home\\identity\\trust\\access.json` — a `home` SUBDIR, which `with_home` never makes (it points `SPT_HOME` at the tempdir *root*). That single mismatch named the real aggressor (`spt_test_support::TestHome`) faster than reading either helper. Corollary for the filed-mechanism trap: `with_home` holds its mutex across its **entire body**, so \"a sibling `with_home` test retargets the home mid-test\" — the filed story — was impossible; read a helper's lock SCOPE before accepting a race that names it.\r\n- **spt-core mapping:** `spt_test_support::env_lock` (the one lease) consumed by `spt_daemon::test_home::{env_lock, with_home}` and `spt::testutil::isolated_home`. Guard: `test_home::tests::with_home_and_testhome_serialize_on_the_same_lease` — a `with_home` body holds the lease while a second thread attempts a `TestHome`, asserting the thread cannot enter and `SPT_HOME` cannot move, **then** that it does proceed once released (so a shared lock is proven to be a lock, not a deadlock). Reds on the two-lock code, greens on one. **Sweep discipline recorded because one instance of a class is not the class:** the population is every crate declaring an `SPT_HOME` helper INTERSECTED with the binaries that also reach `spt_test_support`; running it found a second live, unreported instance (`crates/spt`'s `testutil::LOCK` beside `cli.rs`'s direct `TestHome`). `spt-live` and `spt-store` depend on `spt-test-support` not at all, and `spt-msg` declares no helper of its own.\r\n- **Source:** releases#111 (filed by doyle from hertz's gate observation, 2026-08-02); filed mechanism refuted and the real root measured the same day — hertz. Cousin class, same date: two builds writing one binary path with nothing guarding between them, which is why the gate recipe now identity-checks the exe hash (doyle, W2 gate).\r\n\r\n<!-- [doc->REQ-POOL-FOREIGN-TREE-REFUSED] -->\r\n### 5.20 Two source trees sharing one cargo target directory fabricate reds that belong to neither  `[REQ-POOL-FOREIGN-TREE-REFUSED]`\r\n- **Failure:** a gate lane and a builder lane both built through `.worktrees/gate-target`. The gate compiled against the builder's mid-seam, half-written artifacts and reported an `E0308` in `psyche_event_turn_e2e` that **vanished on re-run** — a red belonging to neither tree, in a lane whose entire job is to be believed. The reverse is worse and silent: the builder's green was equally untrustworthy and nothing said so. Reproduced small (releases#103): two packages of the same name and version, built from two DIFFERENT paths into one pool, resolve to **one** build-script output dir and overwrite each other.\r\n- **Why it hides:** the sharing is invisible at the point of use. A junction shows as an ordinary `target/` and nothing in cargo's output names the real directory; `CARGO_TARGET_DIR` is quieter still — it does not even leave a directory entry to notice afterwards. Both reach the same hazard, which is why the rule is about the **relationship** (this tree writing into a target owned by another) and never about a path: the incident that motivated the filing pointed `CARGO_TARGET_DIR` at the *primary checkout*, which no rule about `.worktrees/` would have covered.\r\n- **The harm is INTERLEAVING, not simultaneity.** Cargo holds an exclusive `.cargo-lock` for a build's duration, so two builds are never literally concurrent — the second blocks. What bit was one lane's artifacts being invalidated by another **between that lane's own steps**. A lease keyed on a `cargo` process therefore guards nothing: it is stale seconds after every claim, so every crossing reads as a takeover and the refusal can never fire. That shape was designed, measured, and refused.\r\n- **Invariant:** a pool belongs to one source tree. `crates/spt-store/build.rs` enforces it and refuses with `SPT_POOL_FOREIGN`, naming the pool, the owning tree, the lane, the holder pid and the way out. Sequential sharing is correct and cheap — a provably-gone lane is a **loud takeover**, never a refusal, because refusing it would demand a pool per lane (30+ worktrees at a measured 7-15 GB each). Staleness is proven from the **process table plus the birth stamp**; UNKNOWN is not stale and proceeds with a warning. An ownerless pool imprints its first builder, so a developer's own fresh `target/` is never refused. `SPT_POOL_UNCHECKED=1` overrides and says so on every build it allows.\r\n<!-- [doc->REQ-POOL-LANE-IDENTITY] -->\r\n- **A DEAD HOLDER IS NOT A FINISHED LANE `[REQ-POOL-LANE-IDENTITY]`.** The first shape of this guard answered \"has that lane finished?\" from the holder process alone. Measured on this box afterwards: **3 of 3 live pool claims had a dead holder, and one of those three lanes was live.** A holder is an agent session or a rig shell — cleared, re-forked, re-parented as a matter of routine — so its death says nothing about the lane, and reading it as \"finished\" hands the pool to a second tree **mid-lane**, i.e. reaches this very hazard *through* the guard. So the claim records the lane's **git identity** (its branch and the base sha that branch carried at claim time) and the finished question is answered by **ancestry**: in flight while the lane's tip is not contained in the integration head; settled once it is merged, once the branch is gone, or once the branch no longer carries the claimed base — a branch name re-pointed onto other work is the branch-level twin of a recycled pid. **The base sha is also the repo-identity witness:** ancestry is read in the *arriving* tree, so a branch absent from a *different* repository would otherwise read as a finished lane; an unanchored claim answers UNKNOWN, never \"settled\". (Found by its own test, which read `Settled: branch no longer exists` out of a directory that was not a repository at all.) **Precedence is asymmetric:** a live holder may only ever ADD a refusal, ancestry alone may declare a lane settled, and a stamp written before the identity fields existed keeps its old behaviour and says so in the line it prints. **What this arm covers, stated exactly:** the enforcer is the build script of the tree that ARRIVES, never the claim it reads, so a lane is protected when the arriving tree carries this change — coverage grows as trees turn over and is never retroactive (measured: a rig whose arriving worktree sat at the pre-identity sha took the pool over, which is the old behaviour working correctly in an old tree). A version line in the stamp cannot fix that and is refused: the tree that must refuse is the one that does not read the new field, so the reader is the problem and not the record. **Every refusal's remedy must be a command that RUNS** — `xtask` depends on `spt-store`, so any command building the tool goes through the refused pool; measured from the refusal state, a remedy naming a bare `cargo run … pool-release` failed with the identical refusal that printed it. The rule is enforced over the whole population of refusal arms, because it was learned once on one arm and re-broken by the next arm added.\r\n- **The guard's own hazard:** the build script must emit **no** `rerun-if` directive. It is re-run because cargo's fingerprint for its unit carries `CARGO_MANIFEST_DIR`, i.e. on exactly the tree ALTERNATION the guard exists to catch. Measured on byte-identical trees, sequence `A B A A B`: no directives → 4 firings; one `rerun-if-changed` → **1**, and the foreign tree never fired it again. `crates/spt-store/tests/pool_guard_canary.rs` reads the shipped build script and reds if a directive appears — a comment would be a prohibition, not a boundary.\r\n- **Source:** BAROMETER W1/H1 window (doyle + todlando, 2026-08-02); design measured and built by hertz, releases#103.\r\n\r\n---\r\n\r\n## 6.

The shell-side twin of REQ-HAZARD-DAEMON-HOSTED-LIVENESS, which gave AGENT perches exactly this resolver and which shells never got. PROVABLY DEAD is the narrow discriminant: `shell.pid` present AND parses non-zero AND `!is_process_alive` — pid absent, unparseable, or 0 (a broker-hosted spawn whose backend exposed no pid records 0) reads ALIVE, the same interim-parity/fail-toward-alive stance `liveness.rs` already holds, so a pid-less backend is NEVER falsely declared dead. Recycled-pid caveat, accepted at mint: a reused pid reads alive, so the heal is missed, never mis-fired — the failure direction is 'stays stale', never 'kills a live instance'. SITE CLASSIFICATION IS PART OF THE REQUIREMENT (authoritative cfg(test)-excluded census at mint = 8 status reads, 3 classes — do NOT blanket-swap the predicate): (a) DERIVED — relink's already-online refusal (the gate that made recovery impossible), the `shell cmd` wake-if-offline arm (which silently spooled to a corpse), the drive drop-if-offline branch, `shelldisc::discover` (the single source of BOTH `shell list` renders, text + --json), and the activity fan-out's online filter; (b) RAW status, deliberately — `bind_shell_by_token`/`close_shell` (the WRITERS) and `cascade_owner_edge`'s suspend-close arm, where routing through the resolver would SKIP the close that is itself the cleanup, removing a heal path; (c) RAW recorded status AND the corpse-boot discriminant — the `shellwake::reconcile_once` watcher-eligibility read. AMENDED BAROMETER W2 (doyle, releases#78 comment 5156810267): this class's original text — 'RAW status, pending an operator ruling', with no spontaneous relaunch of anything — IS STRUCK, because it rested on a fact leg (a) deliberately ends. What actually held a force-killed instance out of the eligible set was the STALE `online` record itself; healing that record to the truth removes the accidental protection, so the guard had to move to a rule that STATES it. Eligibility is now recorded `offline` AND (no corpse, or the corpse's launch PREDATES THE BOOT INSTANT), reusing leg (b)'s `launch_predates_boot` and its slack constant verbatim. NO SPONTANEOUS RELAUNCH OF SAME-BOOT DEATHS: flynn's mid-deploy forcing case (an operator kills the process precisely to free the exe for overwrite — shared install dir ⇒ 'kill the process' is a routine deploy step) is preserved BY CONSTRUCTION, since a force-kill during steady state leaves a corpse launched AFTER boot, which the predicate can never accept; for those, recovery stays demand-driven (an unblocked `relink`, or a `shell cmd` that wakes). Boot-restoration of PRE-boot casualties is enabled, per #78 leg (b)'s operator-greenlit scope and this ruling (#78 thread). CORPSE IS DEFINED ON THE PARKED STAMPS, never on a bare pid re-probe: a RECYCLED pid — alive, but its native start stamp mismatching the one leg (a) parked — is corpse-equivalent because our process is dead, and the parked ABSOLUTE launch stamp is what decides pre/post-boot. Without that, the heal-then-recycle race reads 'alive ⇒ no corpse' on the next tick and walks back into the forbidden shape through a side door. Deriving is still WRONG at this site and this is NOT a swap to class (a): the census stays 8 reads / 3 classes — the site reclassifies, it does not multiply, the do-NOT-blanket-swap sentence above stands, and `shell list` still tells the truth by derivation (class (a), untouched). LOCALITY SYMMETRY (field-caught by flynn's leg-2 run, 2026-07-25): 'a shell cmd that wakes' holds for BOTH the local CLI cmd and the cross-node serve — at mint the wake arm lived in the SHELL_LINK_CMD serve handler only (module docs scoped wake-if-offline to remote cmd), so a LOCAL cmd against a corpse spooled silently and nothing woke, the exact accepted-happily/drained-by-nobody shape this req exists to kill; the arm is now the shared `linkhost::wake_if_offline_persistent`, called by both, and the derived status READ inside it is the same single census site as before (the census of 8 reads/3 classes is unchanged — the read moved, it did not multiply). ROTATION CARRIES THE DURABLE CHANNEL (flynn's frame-loss field catch, 2026-07-25, both trials): a spooled command frame is MAC-stamped under the link token current at SPOOL time, and the drain is a raw destructive passthrough — the shell verifies against its CURRENT key — so a relink's token mint orphaned every pending frame: drained to the woken binary, failed verify, correctly discarded BY THE ADAPTER, lost permanently; the wake-triggering command itself was the frame the wake lost (#23 armed the wake and never answered; #24/#19 spooled after rotation and drained in order). The fix is three-layered (todlando's A1/A2 race+crash hazards addressed at mint): (1) the token mint re-stamps all pending rows old-key→new-key (idempotent, crash-partial converges — an old-stamped remainder is converted by the next rotation or drain); (2) the rotated-out token is STASHED (`link.token.retired`, never a live credential — bind resolves only the parked file) so (3) the drain paths give any race straggler a second-chance re-stamp at delivery (`restamp_for_drain`), while frames verifying under neither key pass through untouched for the adapter to refuse exactly as before. Rows are selected by MAC verification against the threaded new key, never by token-snapshot equality (the D-2 class). MOCK CONFORMANCE IS A PROPERTY OF THE RIG, not a patch (todlando A4): mock-shell MUST verify inbound frame MACs exactly as the public contract demands of a real adapter and drop failures loudly — a mock that accepts what the field rejects is a broken rig, and that exact divergence (credulous mock) is how the frame loss passed the e2e while failing in the field. The adapter-side discard behavior is CORRECT and must never be softened to paper over the spool side. Relink additionally probes LOCALLY rather than trusting a daemon sweep, so recovery holds with the daemon down. RECOVERY PRESERVES CONSUMER STATE (the property consumers actually depend on, flynn 2026-07-25): 'same canonical id, same perch' exists so that state a consumer PERSISTED IN THE PERCH survives the recovery — an adapter's repo binding, a scanner's cursor. The teardown+spawn workaround destroyed exactly that, and its worst cost was SILENT, not the rename: alchemy's tag cursor re-baselines at the digest tip, so tags written between the kill and the re-bind are never scanned — not failed-and-retried, just never seen. A loud failure gets retried; a silent one does not. Gate: int — force-kill a bound persistent instance's process, then prove (1) `shell list` reads offline, (2) `relink` succeeds instead of SHELL_ALREADY_ONLINE and the SAME canonical id + perch survive, carrying perch-persisted consumer state with them (no teardown+spawn, no id churn, no re-baselined cursor), (3) no spontaneous relaunch occurs while the instance sits dead and undriven. FIELD VERDICT — PASS END-TO-END (flynn, alchemy-0, delivered 2026-07-26; v0.43.0, counter 77): every gate leg held in the field, on a record the pre-fix code had already poisoned. (1) `shell list` read OFFLINE while the on-disk info.json still said status=online — the daemon DERIVED offline from the corpse pid (29036 absent from the process table); the record was never corrected and did not need to be. (2) relink ADMITTED, no SHELL_ALREADY_ONLINE — verbatim SHELL_RELINKED:alchemy-0 owner=flynn pid=38644 status=offline, list online thereafter. (3) identity/state integrity: same canonical id, same owner, same perch; repo binding byte-identical (token_provenance=gh-cli); armed=true preserved; no spontaneous relaunch across the ~6.5h dead window. CURSOR SCOPING, ruled at closure (doyle 2026-07-26) — the one non-byte-identical field: the tag cursor moved 206158430541→210453397553 (gen:seq 48:333→49:49) because the recovery crossed a DAEMON restart that slid the retained digest window past the armed cursor. NOT a gap and NOT this req's property failing: spt-core raised after_predates_window and the consumer took its specced armed-cursor branch (alchemy REQ-TAG-SCANNER missed-rows leg — warn the owner, never silently re-baseline an armed cursor; alchemy src/tags.rs, two unit tests) — the FIRST FIELD FIRING of a path previously exercised only by unit tests. The 'no re-baselined cursor' gate property is hereby scoped: byte-identity holds across SHELL death within one daemon generation (the prior LEG 5 measurement, one daemon instance, uncontradicted — different scenario, generation never moved); across a daemon restart that slides the window the contract is DETECT-AND-ANNOUNCE, not preserve — corroborated independently by a second record's cursor decomposing under the same gen:seq scheme (4294967486 = 1:190). Practical exposure in this event: nil (every agent stood down through the gap; no tag traffic to miss). SECOND SPECIMEN HELD, not spent (doyle ruling 2026-07-26): liam's record — precondition verified by flynn (pid 35464 a CLEAN corpse, not recycled, so the accepted-at-mint recycled-pid caveat does not apply; same poisoned status=online shape; binding intact; cursor armed at 4294967486) — is deliberately NOT relinked while its owner is absent: the admit gate is already field-proven, a relink measurably re-baselines the cursor across a daemon-restart boundary, and liam's is the only untouched specimen with the longer (~8.5h) gap — spending it would destroy the cursor datum liam's own return produces, to buy a redundant second sample of a gate already proven to admit. It waits for liam. SPECIMEN HARVESTED (liam's own return, 2026-07-26 — operator-authorized endpoint start executed by doyle; pre-state snapshotted by doyle AND independently re-verified on disk by liam before touching anything): (1) relink ADMITTED at the ~8.5h gap — verbatim SHELL_RELINKED:alchemy-0 owner=liam pid=47608 status=offline (online at bind); the poisoned record did not refuse; info.json online is now TRUE. (2) integrity FULL PASS: id unchanged (no new mint slot), perch onlined at bind, repo binding byte-identical (token_provenance gh-cli), and the ROTATION-CARRIES-THE-DURABLE-CHANNEL machinery observed live in the field for the first time — link.token.retired present beside the fresh mint, and a post-relink round trip proven end-to-end (shell cmd spooled -> engine executed -> reply home on the owner's perch), not merely an outbound spool. (3) cursor, the sharpest datum of the harvest: BYTE-IDENTICAL through the relink itself (4294967486 armed at pid-change instant, doyle's file watch) — the relink preserves; the SCANNER moves. First scan re-baselined 1:190 -> 2:0 silently, and liam PROVED no-fire-by-precondition rather than assuming: the daemon restart bumped the generation but EVICTED NOTHING (window floor 4294967464 < cursor 4294967486, every gen-1 row past the cursor still retained), so after_predates_window is correctly false at every link of the chain (filter_after floor test -> emit-only-when-true -> unwrap_or(false)) and the missed-rows announce had no precondition to fire on. Flynn's earlier gen-bump reading is refined by this: a restart alone does not slide the window; flynn's announce fired because HIS window had genuinely slid. Scope note carried: a valid negative — the fix's announce chain verified link-by-link to contract on a specimen where it correctly stayed quiet. RESIDUE from the harvest (liam's find, alchemy lane, no core REQ): permanently-unsealable turns from a dark session are jumped by scanner cursor advance with no possible missed-rows notice (a generation bump is not a slide); ruled scanner-side announce for input-bearing null-seq jumps, pseudo-turns jump silently by design; core's per-turn input/input_seq/partial already suffice to discriminate.\"\nrequired_stages = [\"doc\", \"impl\", \"unit\", \"int\"]  # ACTIVATED at mint (doyle 2026-07-25) — field-blocking; flynn eats id churn every alchemy release until it lands.

The shell-side twin of REQ-HAZARD-DAEMON-HOSTED-LIVENESS, which gave AGENT perches exactly this resolver and which shells never got. PROVABLY DEAD is the narrow discriminant: `shell.pid` present AND parses non-zero AND `!is_process_alive` — pid absent, unparseable, or 0 (a broker-hosted spawn whose backend exposed no pid records 0) reads ALIVE, the same interim-parity/fail-toward-alive stance `liveness.rs` already holds, so a pid-less backend is NEVER falsely declared dead. Recycled-pid caveat, accepted at mint: a reused pid reads alive, so the heal is missed, never mis-fired — the failure direction is 'stays stale', never 'kills a live instance'. SITE CLASSIFICATION IS PART OF THE REQUIREMENT (authoritative cfg(test)-excluded census at mint = 8 status reads, 3 classes — do NOT blanket-swap the predicate): (a) DERIVED — relink's already-online refusal (the gate that made recovery impossible), the `shell cmd` wake-if-offline arm (which silently spooled to a corpse), the drive drop-if-offline branch, `shelldisc::discover` (the single source of BOTH `shell list` renders, text + --json), and the activity fan-out's online filter; (b) RAW status, deliberately — `bind_shell_by_token`/`close_shell` (the WRITERS) and `cascade_owner_edge`'s suspend-close arm, where routing through the resolver would SKIP the close that is itself the cleanup, removing a heal path; (c) RAW recorded status AND the corpse-boot discriminant — the `shellwake::reconcile_once` watcher-eligibility read. AMENDED BAROMETER W2 (doyle, releases#78 comment 5156810267): this class's original text — 'RAW status, pending an operator ruling', with no spontaneous relaunch of anything — IS STRUCK, because it rested on a fact leg (a) deliberately ends. What actually held a force-killed instance out of the eligible set was the STALE `online` record itself; healing that record to the truth removes the accidental protection, so the guard had to move to a rule that STATES it. Eligibility is now recorded `offline` AND (no corpse, or the corpse's launch PREDATES THE BOOT INSTANT), reusing leg (b)'s `launch_predates_boot` and its slack constant verbatim. NO SPONTANEOUS RELAUNCH OF SAME-BOOT DEATHS: flynn's mid-deploy forcing case (an operator kills the process precisely to free the exe for overwrite — shared install dir ⇒ 'kill the process' is a routine deploy step) is preserved BY CONSTRUCTION, since a force-kill during steady state leaves a corpse launched AFTER boot, which the predicate can never accept; for those, recovery stays demand-driven (an unblocked `relink`, or a `shell cmd` that wakes). Boot-restoration of PRE-boot casualties is enabled, per #78 leg (b)'s operator-greenlit scope and this ruling (#78 thread).

The 'no re-baselined cursor' gate property is hereby scoped: byte-identity holds across SHELL death within one daemon generation (the prior LEG 5 measurement, one daemon instance, uncontradicted — different scenario, generation never moved); across a daemon restart that slides the window the contract is DETECT-AND-ANNOUNCE, not preserve — corroborated independently by a second record's cursor decomposing under the same gen:seq scheme (4294967486 = 1:190). Practical exposure in this event: nil (every agent stood down through the gap; no tag traffic to miss). SECOND SPECIMEN HELD, not spent (doyle ruling 2026-07-26): liam's record — precondition verified by flynn (pid 35464 a CLEAN corpse, not recycled, so the accepted-at-mint recycled-pid caveat does not apply; same poisoned status=online shape; binding intact; cursor armed at 4294967486) — is deliberately NOT relinked while its owner is absent: the admit gate is already field-proven, a relink measurably re-baselines the cursor across a daemon-restart boundary, and liam's is the only untouched specimen with the longer (~8.5h) gap — spending it would destroy the cursor datum liam's own return produces, to buy a redundant second sample of a gate already proven to admit. It waits for liam. SPECIMEN HARVESTED (liam's own return, 2026-07-26 — operator-authorized endpoint start executed by doyle; pre-state snapshotted by doyle AND independently re-verified on disk by liam before touching anything): (1) relink ADMITTED at the ~8.5h gap — verbatim SHELL_RELINKED:alchemy-0 owner=liam pid=47608 status=offline (online at bind); the poisoned record did not refuse; info.json online is now TRUE. (2) integrity FULL PASS: id unchanged (no new mint slot), perch onlined at bind, repo binding byte-identical (token_provenance gh-cli), and the ROTATION-CARRIES-THE-DURABLE-CHANNEL machinery observed live in the field for the first time — link.token.retired present beside the fresh mint, and a post-relink round trip proven end-to-end (shell cmd spooled -> engine executed -> reply home on the owner's perch), not merely an outbound spool. (3) cursor, the sharpest datum of the harvest: BYTE-IDENTICAL through the relink itself (4294967486 armed at pid-change instant, doyle's file watch) — the relink preserves; the SCANNER moves. First scan re-baselined 1:190 -> 2:0 silently, and liam PROVED no-fire-by-precondition rather than assuming: the daemon restart bumped the generation but EVICTED NOTHING (window floor 4294967464 < cursor 4294967486, every gen-1 row past the cursor still retained), so after_predates_window is correctly false at every link of the chain (filter_after floor test -> emit-only-when-true -> unwrap_or(false)) and the missed-rows announce had no precondition to fire on. Flynn's earlier gen-bump reading is refined by this: a restart alone does not slide the window; flynn's announce fired because HIS window had genuinely slid. Scope note carried: a valid negative — the fix's announce chain verified link-by-link to contract on a specimen where it correctly stayed quiet. RESIDUE from the harvest (liam's find, alchemy lane, no core REQ): permanently-unsealable turns from a dark session are jumped by scanner cursor advance with no possible missed-rows notice (a generation bump is not a slide); ruled scanner-side announce for input-bearing null-seq jumps, pseudo-turns jump silently by design; core's per-turn input/input_seq/partial already suffice to discriminate.\"\r\nrequired_stages = [\"doc\", \"impl\", \"unit\", \"int\"]  # ACTIVATED at mint (doyle 2026-07-25) — field-blocking; flynn eats id churn every alchemy release until it lands.

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 recovers the instance) refuses `SHELL_ALREADY_ONLINE`, gated on the very state that is wrong; and `shell cmd`'s wake-if-offline arm reads \"not offline\", skips the wake, and spools the command to a corpse — accepted happily, drained by nobody, **indistinguishable from a busy shell**. The only exit was `teardown` + `spawn`, which destroys the perch (losing the instance's persisted state) and frees the mint slot, so the instance returns under a **different canonical id** and every reference to the old name — docs, other agents' notes, tag addressing — silently points at nothing. The rename is the *visible* cost; the expensive one is **silent**: a consumer's perch-persisted cursor re-baselines on the fresh perch, so work arriving between the death and the re-bind is never scanned — not failed-and-retried, just never seen (alchemy's tag scanner, 2026-07-25). Recovery must therefore preserve the perch, not merely restore a running binary.\n78:- **Invariant:** ONLINE-ness is **derived**, never the recorded field alone: `status == online` **AND** the recorded `shell.pid` is not *provably* dead. Provably dead is narrow — pid parked, non-zero, `!is_process_alive`; pid absent, unparseable, or `0` (a broker-hosted spawn whose backend exposed no pid) reads **alive**, the same fail-toward-alive parity 2.5 holds, so a backend the resolver cannot see is never declared dead. **The recycled-pid caveat is narrowed since BAROMETER W2 and is now conditional on the stamp:** a launch parks a **birth stamp** beside the pid (`shell.launch.json`), and the probe runs the PAIR test — same pid, *different* start time ⇒ **gone**, so a pid the OS handed to an unrelated process no longer masks a dead instance. That case matters most across a restart, where the pid namespace resets and a corpse pid is routinely reused; without the pair test the corpse reads alive, the derived status reads `online`, and `relink` refuses `SHELL_ALREADY_ONLINE` on the one instance needing recovery. Where there is **no stamp to compare** (an instance last launched by a pre-W2 build, or a backend exposing no start time) the original stance is unchanged and unchanged in *direction*: fail toward alive, heal *missed* rather than *mis-fired*. Derivation NEVER promotes: a recorded-`offline` instance stays offline whatever its pid file says. Site class is part of the invariant: **derive** at the gates and renders (relink, the cmd wake arm, drive's drop-if-offline, `shelldisc::discover` = the single source of both `shell list` surfaces, the activity fan-out); keep the **recorded** field at the two writers and at the owner-suspend cascade, whose `close_shell` **is** the cleanup that would be skipped; and keep it at the wake reconciler's eligibility read, which since BAROMETER W2 additionally asks the **corpse-boot discriminant** (releases#78, doyle's amendment on comment 5156810267): the read stays on the recorded field, but \"no spontaneous relaunch\" is now a stated predicate rather than a side effect of the record being wrong — see the bullet below.\n79:- **No spontaneous relaunch of a NONPERSISTENT same-boot death:** the releases#78 force-kill freeze still protects nonpersistent instances, so killing one to free its exe does not arm a watcher underneath an overwrite. Recovery remains demand-driven. **Persistent instances are exempt** (operator ruling, releases#287): a kill is not a request to keep a declared-persistent shell down; use `teardown` or a nonpersistent manifest instead.\n80:- **Watcher eligibility:** recorded `offline`, no live binary awaiting bind, and either `persistent`, no corpse, or a corpse whose launch predates the machine boot instant. A nonpersistent corpse without a launch stamp or boot oracle remains frozen; persistent instances require neither to become eligible. Birth-safe probes prevent a recycled pid from masquerading as a live shell.\n81:- **spt-core mapping:** `spt_store::shellinfo::{shell_pid_provably_dead, effective_status, is_shell_online}` (the resolver — the shell-side twin of 2.5's `liveness.rs`, which gave *agent* perches exactly this and which shells never got); consumers in `linkhost::{relink_shell, prepare_drive, run_action}`, `shelldisc::discover`, `activity::observe_links`; the class-(c) eligibility read is `spt_daemon::shellwake::watcher_eligible` (+ `launch_predates_boot`, `BOOT_RESTORE_SLACK_MS`), and the birth stamp it rests on is `shellinfo::{ShellLaunch, record_shell_launch, read_shell_launch}`.\n82:- **Source:** spt-core, flynn's spt-alchemy field report (2026-07-25) — a deterministic recipe, not a race.

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.\n86:- **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 a clean-looking context render must never be taken as proof the class did not occur. The correct falsifier is the **on-disk record**.\n87:- **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. The test is not weak; it gives a true answer to the wrong question, so a reader asking \"is the cascade covered?\" is told yes. This is the third suppressed-arm instance found in one week, and the pattern is the same each time: **a fixture that establishes the precondition the code under test is supposed to establish.**\n88:- **Invariant:** a daemon-only or machine restart must not strand a persistent instance. **(a) Heal:** every reconcile cycle writes `offline` only where the derived birth-safe read contradicts recorded `online`; already-correct records are untouched. **(b) Restore:** the once-per-daemon-generation boot sweep and every owner offline→online edge run the same per-owner body. Relaunch every instance whose adapter declares `persistent`, whose owner is online, and whose binary is down in fact. There is **no machine-boot, launch-age, or stamp-presence eligibility gate**. A live binary awaiting bind is not down and must not be duplicated; missing birth evidence keeps the existing fail-toward-alive liveness behavior. The owner-online trigger remains an edge, bounding failed launches to one attempt per event.\n89:- **Regression shape:** construct recorded `online` over a corpse **without a suspend edge**, including a launch **after machine boot**, then bring its owner online after a spent boot sweep. Every stranded persistent sibling must be restored; offline owners and nonpersistent instances are not restored. Separately defend live/binding exclusion and the nonpersistent watcher freeze. Suspending in setup suppresses the failing arm and proves nothing about this class.\n90:- **Per-owner enumeration:** the existing `SHELL_RECORD_HEALED:<owner>/<shell_id>` daemon diagnostic names **every** successfully healed instance, not one representative.

Where there is **no stamp to compare** (an instance last launched by a pre-W2 build, or a backend exposing no start time) the original stance is unchanged and unchanged in *direction*: fail toward alive, heal *missed* rather than *mis-fired*. Derivation NEVER promotes: a recorded-`offline` instance stays offline whatever its pid file says. Site class is part of the invariant: **derive** at the gates and renders (relink, the cmd wake arm, drive's drop-if-offline, `shelldisc::discover` = the single source of both `shell list` surfaces, the activity fan-out); keep the **recorded** field at the two writers and at the owner-suspend cascade, whose `close_shell` **is** the cleanup that would be skipped; and keep it at the wake reconciler's eligibility read, which since BAROMETER W2 additionally asks the **corpse-boot discriminant** (releases#78, doyle's amendment on comment 5156810267): the read stays on the recorded field, but \"no spontaneous relaunch\" is now a stated predicate rather than a side effect of the record being wrong — see the bullet below.\n-79|- **No spontaneous relaunch of a SAME-BOOT death (operator-ratified, flynn 2026-07-25; re-based BAROMETER W2):** the reconciler does NOT adopt an instance whose binary died during this boot. Every reason an operator stops a shell is a reason not to want it back a tick later: mid-deploy (a shared install dir makes \"kill the process\" routine on Windows, since a running exe cannot be overwritten) an auto-relaunch would run the **old** binary out of the file being replaced — worse than a failed install — and it turns quarantining a misbehaving shell into a restart loop. For those, recovery stays demand-driven: `relink`, or a `shell cmd` that wakes. `relink` probes **locally** rather than trusting a daemon sweep, so recovery holds with the daemon down.\n-80|- **What holds that open is no longer the stale record (BAROMETER W2):** until W2 the guarantee rested on an accident: a force-killed instance was held out of the eligible set because its record still said `online`, and the eligibility read took that field raw. 2.7 heals that record to the truth, which removes the accidental protection — so the guard had to move to a rule that *states* it. Eligibility is now recorded-`offline` **AND** (no corpse, **or** the corpse's recorded launch **predates the boot instant**). A steady-state force-kill leaves a corpse launched *after* boot, which the predicate can never accept, so the ruling is preserved **by construction** rather than by a second rule. A restart casualty is the one case the predicate does accept, and it is exactly the scope 2.7 was greenlit for. Where the discriminant **cannot be evaluated** — no launch stamp (an instance last launched by a pre-W2 build), or no boot oracle on the platform — a corpse-bearing instance is **not** eligible: leaving a shell down beats arming a relaunch of a binary an operator may have killed on purpose.\n+79|- **No spontaneous relaunch of a NONPERSISTENT same-boot death:** the releases#78 force-kill freeze still protects nonpersistent instances, so killing one to free its exe does not arm a watcher underneath an overwrite. Recovery remains demand-driven. **Persistent instances are exempt** (operator ruling, releases#287): a kill is not a request to keep a declared-persistent shell down; use `teardown` or a nonpersistent manifest instead.\n+80|- **Watcher eligibility:** recorded `offline`, no live binary awaiting bind, and either `persistent`, no corpse, or a corpse whose launch predates the machine boot instant. A nonpersistent corpse without a launch stamp or boot oracle remains frozen; persistent instances require neither to become eligible.

A machine death breaks no link, so `close_shell` never runs and 2.6's stale record survives the reboot; when the owner comes back online, the wake cascade reads the **recorded** field, sees `online`, and skips the relaunch of a binary that has not existed since the previous boot. Nothing else corrects it: the instance is down forever, with no error anywhere, until a human happens to run `relink`. Every `persistent` instance on the node is stranded by one restart, together.\n+84|### 2.7 A daemon or machine restart strands `persistent` shells — and a graceful cascade fixture suppresses the failing arm `[REQ-HAZARD-RESTART-STRANDS-PERSISTENT-SHELLS]`\n+85|- **Failure:** a restart can leave an `online` record over a corpse without a link-break or suspend edge. 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 86|- **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 a clean-looking context render must never be taken as proof the class did not occur. The correct falsifier is the **on-disk record**.\n 87|- **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. The test is not weak; it gives a true answer to the wrong question, so a reader asking \"is the cascade covered?\" is told yes. This is the third suppressed-arm instance found in one week, and the pattern is the same each time: **a fixture that establishes the precondition the code under test is supposed to establish.**\n-88|- **Invariant:** a node restart must not strand a `persistent` instance. Two legs, and each is worthless alone. **(a) The record stops lying:** the daemon-side reconciler heals a recorded `online` that 2.6's derivation contradicts, writing `offline` — every cycle, **guarded on an actual change** (a heal that rewrote each tick would be a stream of identical writes and would destroy the record's mtime as a signal). **(b) The restart shape reaches a restoration path:** a once-per-daemon-generation boot sweep — and, for an owner that comes online after that sweep has run, an **owner offline→online edge** in the reconcile loop running the identical body (releases#228) — relaunches an instance when **all four** hold — the adapter section declares `persistent`; the **owner endpoint is online** (an offline owner is owed nothing — that is the line between healing a record and resurrecting a shell nobody is there to drive); the instance is down **in fact** (the derived read, made trustworthy across a pid reuse by 2.6's birth stamp); and its recorded launch **predates the boot instant**. No stamp ⇒ **not restored** (the sweep cannot prove it predates boot); no boot oracle on the platform ⇒ nothing restored at all. The boot instant is derived (Linux `btime`; Windows now − `GetTickCount64`), so a named slack constant absorbs derivation jitter and keeps a process launched moments after boot from reading as a corpse from the previous one. **The once-ness of the sweep is scheduling, not safety** (ruled releases#228): the predates-boot discriminant is what forbids relaunching a force-killed shell, and it is monotone within a machine boot — every launch restamps, a kill never does — so a second trigger evaluating the same conjuncts can only refuse more. The second trigger is an **edge**, not the level “owner is online”, which is what bounds a failing launch to one attempt per owner-online event instead of one per reconcile tick.\n-89|- **Regression shape (the row the suppressed fixture cannot express):** construct the restart shape **without a suspend edge** — an instance whose record says `online` over a corpse that predates boot, with an online owner — and assert it is restored.

Relaunch every instance whose adapter declares `persistent`, whose owner is online, and whose binary is down in fact. There is **no machine-boot, launch-age, or stamp-presence eligibility gate**. A live binary awaiting bind is not down and must not be duplicated; missing birth evidence keeps the existing fail-toward-alive liveness behavior. The owner-online trigger remains an edge, bounding failed launches to one attempt per event.\n+89|- **Regression shape:** construct recorded `online` over a corpse **without a suspend edge**, including a launch **after machine boot**, then bring its owner online after a spent boot sweep.

Covers \"owner already up.\" **Node-qualified once instances span nodes** (ruled 2026-07-24, #70 grill): when an owner comes online at a given node, only the **latest** instances qualified to that *endpoint@node* pairing come online with it — a stale instance of the same shell left on another node does not auto-wake alongside. **A node restart is covered by a boot sweep, and an owner that comes online after that sweep by an owner-online edge** (BAROMETER W2 releases#78; CONDUIT W2 releases#228): a machine death breaks no link, so the instance's record survives the reboot still saying `online` and the wake cascade — which reads the *recorded* field — skips it, stranding every `persistent` instance on the node at once. The daemon therefore (i) heals a recorded `online` its derived status contradicts, every reconcile cycle, writing only when the value actually changes, and (ii) runs a **once-per-daemon-generation boot sweep** that relaunches an instance when **all four** conditions hold: the adapter declares `persistent`; the **owner endpoint is online** (an offline owner is owed nothing); the instance is down **in fact**; and its **recorded launch predates the boot instant**. A launch parks a **birth stamp** beside the pid to make that last question answerable — **no stamp ⇒ not restored** (the sweep cannot prove the corpse predates boot, and leaving a shell down beats relaunching a binary an operator may have killed deliberately), and a platform with no boot oracle restores nothing. A shell force-killed *during* this boot is launched after it, can never satisfy the predicate, and so is never spontaneously relaunched — the deploy/quarantine ruling of KNOWN-HAZARDS 2.6 preserved by construction. <!-- [doc->REQ-SHELL-PERSISTENT-BOOT-RESTORE] -->\n-392|  **Daemons boot before endpoints do, so the sweep is not the only trigger** (releases#228): an owner that is not yet online when the sweep runs is skipped by that very conjunct, and — the sweep being once per daemon generation, and bringup from offline emitting no rest edge — nothing revisited it, so its shells stayed down until a human relinked. The reconcile loop therefore runs the **same four conditions** for every owner that has gone **offline→online since the last pass**. The trigger is that **edge, never the level “the owner is online”**: a successful restore restamps itself out of eligibility, but a *failing* launch under a level trigger would be retried every reconcile tick for as long as the owner stayed up, where the edge bounds it to one attempt per owner-online event. Re-evaluating later in a generation can only refuse **more**, never less — every launch path restamps the birth stamp, a kill never does, and the boot instant is fixed for the machine boot — so the force-kill ruling above is preserved identically on the second trigger. <!-- [doc->REQ-SHELL-OWNER-ONLINE-RESTORE] -->\n-393|- **`wake_command`** (template): a long-running **wake-watcher** process spt-core runs *while the shell is offline* **and eligible** (the eligibility rule is below — an offline instance sitting on a same-boot corpse arms no watcher).

A **once-per-daemon-generation boot sweep** restores every down persistent instance whose owner is online, after a machine reboot **or a daemon-only restart**. Birth-safe liveness protects both an online binary and a live launch awaiting bind. Machine boot time, recorded launch age, and missing launch stamps do **not** gate restoration (releases#287 operator ruling).

The edge is seeded before the sweep; a live launch awaiting bind prevents duplicate launch if both triggers reach it.

Eligibility is recorded-`offline` **AND** (no corpse, **or** the corpse's launch predates the boot instant); an instance whose corpse cannot be dated — no birth stamp, or no boot oracle on the platform — is treated as ineligible rather than guessed at. Only a cleanly-closed instance and a **restart casualty** arm a watcher. The reason is the deploy case: on Windows an operator kills a shell precisely to free its exe for overwrite, and a watcher armed there would re-lock the file under them.\n+395|**Online/offline are mutually-exclusive processes:** a live shell binary (including a launch awaiting bind) excludes its wake-watcher. A recorded-offline instance is watcher-eligible when it is persistent, carries no corpse, or its corpse's launch predates machine boot. **Only nonpersistent instances retain the same-boot force-kill freeze:** their same-boot or undatable corpses arm no watcher, preserving the deploy/overwrite case. A persistent corpse bypasses that freeze even without a launch stamp or boot oracle (releases#287). Missing birth evidence retains the existing fail-toward-alive process probe; it is not itself a restore refusal.\n 396|\n 397|**Exit-opcode supervision:** the wake-watcher exiting with the **wake opcode** → spt-core runs the wake resolution (below) and brings the shell online.

An instance whose binary died **during this boot** (force-kill, crash) arms no watcher and returns only on demand (`relink`, or a waking `shell cmd`), because killing a shell to overwrite its exe is a routine deploy step and a watcher armed underneath would re-lock the file; an instance whose corpse cannot be dated (no launch stamp, or no boot oracle on the platform) is treated the same way rather than guessed at. `persistent` auto-onlines the shell with its owner, and across a **node restart** — where nothing breaks the link, so the instance's record survives the reboot still claiming it is up — the daemon heals that record and a **once-per-daemon-generation boot sweep** relaunches the instance if its adapter is `persistent`, its owner endpoint is online, it is down in fact, and its recorded launch predates the boot instant. Because daemons boot before endpoints do, the same four conditions are re-run for any owner that goes **offline→online since the last reconcile pass** (releases#228) — without that edge, an owner that was still down when the sweep ran keeps its shells down until someone relinks by hand. It is an edge and not the level “the owner is online” so that a failing launch is attempted once per owner-online event rather than once per tick. `can_shutdown` authorizes `api owner-shutdown`. Cross-node *fresh-spawn* to wake an owner requires the owner's `shell_wake_spawn_anywhere` settings flag (pre-consent).\n+791|**Sleep/wake:** when offline **and eligible** (+ `wake_command` set), spt-core runs the wake-watcher, mutually exclusive with a live shell binary including one awaiting bind. Exit code **86** is the wake opcode; other exits respawn with exponential backoff and eventual give-up until the next shell launch. Templates fill `{id}`, `{adapter_name}`, `{link_token}`, `{adapter_dir}` (not `{perch_dir}`, which is spawn-only). The watcher's link token is minted *unparked*: it wakes by exit code, never by driving an offline link.\n 792|\n+793|**Persistent restoration:** on the once-per-daemon-generation boot sweep and each owner offline→online edge, spt-core restores **every** down persistent instance whose owner is online. This covers machine reboots and daemon-only restarts. The decision uses birth-safe liveness, not machine boot time or recorded launch age; a missing launch stamp does not disqualify a down instance.

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 recovers the instance) refuses `SHELL_ALREADY_ONLINE`, gated on the very state that is wrong; and `shell cmd`'s wake-if-offline arm reads \"not offline\", skips the wake, and spools the command to a corpse — accepted happily, drained by nobody, **indistinguishable from a busy shell**. The only exit was `teardown` + `spawn`, which destroys the perch (losing the instance's persisted state) and frees the mint slot, so the instance returns under a **different canonical id** and every reference to the old name — docs, other agents' notes, tag addressing — silently points at nothing. The rename is the *visible* cost; the expensive one is **silent**: a consumer's perch-persisted cursor re-baselines on the fresh perch, so work arriving between the death and the re-bind is never scanned — not failed-and-retried, just never seen (alchemy's tag scanner, 2026-07-25). Recovery must therefore preserve the perch, not merely restore a running binary.\n 78|- **Invariant:** ONLINE-ness is **derived**, never the recorded field alone: `status == online` **AND** the recorded `shell.pid` is not *provably* dead. Provably dead is narrow — pid parked, non-zero, `!is_process_alive`; pid absent, unparseable, or `0` (a broker-hosted spawn whose backend exposed no pid) reads **alive**, the same fail-toward-alive parity 2.5 holds, so a backend the resolver cannot see is never declared dead. **The recycled-pid caveat is narrowed since BAROMETER W2 and is now conditional on the stamp:** a launch parks a **birth stamp** beside the pid (`shell.launch.json`), and the probe runs the PAIR test — same pid, *different* start time ⇒ **gone**, so a pid the OS handed to an unrelated process no longer masks a dead instance. That case matters most across a restart, where the pid namespace resets and a corpse pid is routinely reused; without the pair test the corpse reads alive, the derived status reads `online`, and `relink` refuses `SHELL_ALREADY_ONLINE` on the one instance needing recovery. Where there is **no stamp to compare** (an instance last launched by a pre-W2 build, or a backend exposing no start time) the original stance is unchanged and unchanged in *direction*: fail toward alive, heal *missed* rather than *mis-fired*. Derivation NEVER promotes: a recorded-`offline` instance stays offline whatever its pid file says. Site class is part of the invariant: **derive** at the gates and renders (relink, the cmd wake arm, drive's drop-if-offline, `shelldisc::discover` = the single source of both `shell list` surfaces, the activity fan-out); keep the **recorded** field at the two writers and at the owner-suspend cascade, whose `close_shell` **is** the cleanup that would be skipped; and keep it at the wake reconciler's eligibility read, which since BAROMETER W2 additionally asks the **corpse-boot discriminant** (releases#78, doyle's amendment on comment 5156810267): the read stays on the recorded field, but \"no spontaneous relaunch\" is now a stated predicate rather than a side effect of the record being wrong — see the bullet below.\n-79|- **No spontaneous relaunch of a SAME-BOOT death (operator-ratified, flynn 2026-07-25; re-based BAROMETER W2):** the reconciler does NOT adopt an instance whose binary died during this boot. Every reason an operator stops a shell is a reason not to want it back a tick later: mid-deploy (a shared install dir makes \"kill the process\" routine on Windows, since a running exe cannot be overwritten) an auto-relaunch would run the **old** binary out of the file being replaced — worse than a failed install — and it turns quarantining a misbehaving shell into a restart loop. For those, recovery stays demand-driven: `relink`, or a `shell cmd` that wakes. `relink` probes **locally** rather than trusting a daemon sweep, so recovery holds with the daemon down.\n-80|- **What holds that open is no longer the stale record (BAROMETER W2):** until W2 the guarantee rested on an accident: a force-killed instance was held out of the eligible set because its record still said `online`, and the eligibility read took that field raw. 2.7 heals that record to the truth, which removes the accidental protection — so the guard had to move to a rule that *states* it. Eligibility is now recorded-`offline` **AND** (no corpse, **or** the corpse's recorded launch **predates the boot instant**). A steady-state force-kill leaves a corpse launched *after* boot, which the predicate can never accept, so the ruling is preserved **by construction** rather than by a second rule. A restart casualty is the one case the predicate does accept, and it is exactly the scope 2.7 was greenlit for. Where the discriminant **cannot be evaluated** — no launch stamp (an instance last launched by a pre-W2 build), or no boot oracle on the platform — a corpse-bearing instance is **not** eligible: leaving a shell down beats arming a relaunch of a binary an operator may have killed on purpose.\n+79|- **No spontaneous relaunch of a NONPERSISTENT same-boot death:** the releases#78 force-kill freeze still protects nonpersistent instances, so killing one to free its exe does not arm a watcher underneath an overwrite. Recovery remains demand-driven. **Persistent instances are exempt** (operator ruling, releases#287): a kill is not a request to keep a declared-persistent shell down; use `teardown` or a nonpersistent manifest instead.\n+80|- **Watcher eligibility:** recorded `offline`, no live binary awaiting bind, and either `persistent`, no corpse, or a corpse whose launch predates the machine boot instant. A nonpersistent corpse without a launch stamp or boot oracle remains frozen; persistent instances require neither to become eligible. Birth-safe probes prevent a recycled pid from masquerading as a live shell.\n 81|- **spt-core mapping:** `spt_store::shellinfo::{shell_pid_provably_dead, effective_status, is_shell_online}` (the resolver — the shell-side twin of 2.5's `liveness.rs`, which gave *agent* perches exactly this and which shells never got); consumers in `linkhost::{relink_shell, prepare_drive, run_action}`, `shelldisc::discover`, `activity::observe_links`; the class-(c) eligibility read is `spt_daemon::shellwake::watcher_eligible` (+ `launch_predates_boot`, `BOOT_RESTORE_SLACK_MS`), and the birth stamp it rests on is `shellinfo::{ShellLaunch, record_shell_launch, read_shell_launch}`.\n 82|- **Source:** spt-core, flynn's spt-alchemy field report (2026-07-25) — a deterministic recipe, not a race.

A machine death breaks no link, so `close_shell` never runs and 2.6's stale record survives the reboot; when the owner comes back online, the wake cascade reads the **recorded** field, sees `online`, and skips the relaunch of a binary that has not existed since the previous boot. Nothing else corrects it: the instance is down forever, with no error anywhere, until a human happens to run `relink`. Every `persistent` instance on the node is stranded by one restart, together.\n+84|### 2.7 A daemon or machine restart strands `persistent` shells — and a graceful cascade fixture suppresses the failing arm `[REQ-HAZARD-RESTART-STRANDS-PERSISTENT-SHELLS]`\n+85|- **Failure:** a restart can leave an `online` record over a corpse without a link-break or suspend edge. 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 86|- **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 a clean-looking context render must never be taken as proof the class did not occur. The correct falsifier is the **on-disk record**.\n 87|- **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. The test is not weak; it gives a true answer to the wrong question, so a reader asking \"is the cascade covered?\" is told yes. This is the third suppressed-arm instance found in one week, and the pattern is the same each time: **a fixture that establishes the precondition the code under test is supposed to establish.**\n-88|- **Invariant:** a node restart must not strand a `persistent` instance. Two legs, and each is worthless alone. **(a) The record stops lying:** the daemon-side reconciler heals a recorded `online` that 2.6's derivation contradicts, writing `offline` — every cycle, **guarded on an actual change** (a heal that rewrote each tick would be a stream of identical writes and would destroy the record's mtime as a signal). **(b) The restart shape reaches a restoration path:** a once-per-daemon-generation boot sweep — and, for an owner that comes online after that sweep has run, an **owner offline→online edge** in the reconcile loop running the identical body (releases#228) — relaunches an instance when **all four** hold — the adapter section declares `persistent`; the **owner endpoint is online** (an offline owner is owed nothing — that is the line between healing a record and resurrecting a shell nobody is there to drive); the instance is down **in fact** (the derived read, made trustworthy across a pid reuse by 2.6's birth stamp); and its recorded launch **predates the boot instant**. No stamp ⇒ **not restored** (the sweep cannot prove it predates boot); no boot oracle on the platform ⇒ nothing restored at all. The boot instant is derived (Linux `btime`; Windows now − `GetTickCount64`), so a named slack constant absorbs derivation jitter and keeps a process launched moments after boot from reading as a corpse from the previous one. **The once-ness of the sweep is scheduling, not safety** (ruled releases#228): the predates-boot discriminant is what forbids relaunching a force-killed shell, and it is monotone within a machine boot — every launch restamps, a kill never does — so a second trigger evaluating the same conjuncts can only refuse more. The second trigger is an **edge**, not the level “owner is online”, which is what bounds a failing launch to one attempt per owner-online event instead of one per reconcile tick.\n-89|- **Regression shape (the row the suppressed fixture cannot express):** construct the restart shape **without a suspend edge** — an instance whose record says `online` over a corpse that predates boot, with an online owner — and assert it is restored. A fixture that suspends first re-creates the suppressed arm and proves nothing about this class.\n-90|- **spt-core mapping:** `spt_daemon::shellwake::{heal_stale_online_records, restore_persistent_shells_at_boot, restore_persistent_shells_on_owner_online, OwnerOnlineEdge, launch_predates_boot, BOOT_RESTORE_SLACK_MS}`; `spt_store::proc::boot_instant_ms`; `spt_store::shellinfo::{ShellLaunch, record_shell_launch, read_shell_launch}` (the birth stamp, parked at the two production pid-write sites the launch-site census identified).\n-91|- **Source:** spt-core, BAROMETER W2 (releases#78) — field specimen `liam/alchemy-0`, a genuinely stranded record: `online` over a dead pid, no launch stamp, days old.\n+88|- **Invariant:** a daemon-only or machine restart must not strand a persistent instance. **(a) Heal:** every reconcile cycle writes `offline` only where the derived birth-safe read contradicts recorded `online`; already-correct records are untouched. **(b) Restore:** the once-per-daemon-generation boot sweep and every owner offline→online edge run the same per-owner body. Relaunch every instance whose adapter declares `persistent`, whose owner is online, and whose binary is down in fact. There is **no machine-boot, launch-age, or stamp-presence eligibility gate**. A live binary awaiting bind is not down and must not be duplicated; missing birth evidence keeps the existing fail-toward-alive liveness behavior. The owner-online trigger remains an edge, bounding failed launches to one attempt per event.\n+89|- **Regression shape:** construct recorded `online` over a corpse **without a suspend edge**, including a launch **after machine boot**, then bring its owner online after a spent boot sweep.

That reply is\r\n  reported as a **failure** (`SHELL_REMOTE_FORCE_UNHONORED`), never as success:\r\n  under `--force` \"it was already up\" is precisely the thing that did not\r\n  happen.\r\n\r\n## Teach the agent about your shell: `[[hints]]`\r\n\r\n<!-- [doc->REQ-SHELL-HINTS] -->\r\n\r\nA shell adapter can declare `[[hints]]` exactly like a harness adapter — it is a\r\ntop-level manifest section, not a harness-only one:\r\n\r\n```toml\r\n[[hints]]\r\nkeywords = [\"screenshot\", \"what's on screen\"]\r\ntext = \"the PACER shell can capture a window: `spt shell cmd PACER-0 capture <window>`\"\r\n```\r\n\r\nEach hint fires **once per session**, and your adapter contributes **at most one\r\nline per message** (the per-source cap — the harness gets one, and so does every\r\nother shell adapter, so a second shell can never be silenced by a chatty first).\r\nWhich line the agent sees depends on **instantiation, never on link state**:\r\n\r\n- the owner **holds an instance** of your adapter → the **full** hint text,\r\n  whether that instance is online or offline;\r\n- the owner holds **no instance** → a **teaser** naming the keyword that fired\r\n  and the command that shows the text: `spt adapter hints <adapter>`.\r\n\r\nThat command is also how you read your own hints back:\r\n\r\n```console\r\n$ spt adapter hints spt-shell-notify\r\n[screenshot, what's on screen] the PACER shell can capture a window: …\r\n```\r\n\r\nIt resolves the merged view, so a profile's `[[hints]]` overlay is what prints —\r\nand it prints nothing (exit 0) for an adapter that declares none.\r\n\r\n### How a keyword matches\r\n\r\n<!-- [doc->REQ-MANIFEST-4] -->\r\n\r\nBy default, each keyword is a **case-insensitive substring**: there are no word\r\nboundaries, whitespace is literal, and symbols match as written with no escaping.\r\n\r\nSet `regex = true` on a `[[hints]]` row to compile its keywords as regular\r\nexpressions.

The shell-side twin of REQ-HAZARD-DAEMON-HOSTED-LIVENESS, which gave AGENT perches exactly this resolver and which shells never got. PROVABLY DEAD is the narrow discriminant: `shell.pid` present AND parses non-zero AND `!is_process_alive` — pid absent, unparseable, or 0 (a broker-hosted spawn whose backend exposed no pid records 0) reads ALIVE, the same interim-parity/fail-toward-alive stance `liveness.rs` already holds, so a pid-less backend is NEVER falsely declared dead. Recycled-pid caveat, accepted at mint: a reused pid reads alive, so the heal is missed, never mis-fired — the failure direction is 'stays stale', never 'kills a live instance'. SITE CLASSIFICATION IS PART OF THE REQUIREMENT (authoritative cfg(test)-excluded census at mint = 8 status reads, 3 classes — do NOT blanket-swap the predicate): (a) DERIVED — relink's already-online refusal (the gate that made recovery impossible), the `shell cmd` wake-if-offline arm (which silently spooled to a corpse), the drive drop-if-offline branch, `shelldisc::discover` (the single source of BOTH `shell list` renders, text + --json), and the activity fan-out's online filter; (b) RAW status, deliberately — `bind_shell_by_token`/`close_shell` (the WRITERS) and `cascade_owner_edge`'s suspend-close arm, where routing through the resolver would SKIP the close that is itself the cleanup, removing a heal path; (c) RAW recorded status AND the corpse-boot discriminant — the `shellwake::reconcile_once` watcher-eligibility read. AMENDED BAROMETER W2 (doyle, releases#78 comment 5156810267): this class's original text — 'RAW status, pending an operator ruling', with no spontaneous relaunch of anything — IS STRUCK, because it rested on a fact leg (a) deliberately ends. What actually held a force-killed instance out of the eligible set was the STALE `online` record itself; healing that record to the truth removes the accidental protection, so the guard had to move to a rule that STATES it. Eligibility is now recorded `offline` AND (no corpse, or the corpse's launch PREDATES THE BOOT INSTANT), reusing leg (b)'s `launch_predates_boot` and its slack constant verbatim. NO SPONTANEOUS RELAUNCH OF SAME-BOOT DEATHS: flynn's mid-deploy forcing case (an operator kills the process precisely to free the exe for overwrite — shared install dir ⇒ 'kill the process' is a routine deploy step) is preserved BY CONSTRUCTION, since a force-kill during steady state leaves a corpse launched AFTER boot, which the predicate can never accept; for those, recovery stays demand-driven (an unblocked `relink`, or a `shell cmd` that wakes). Boot-restoration of PRE-boot casualties is enabled, per #78 leg (b)'s operator-greenlit scope and this ruling (#78 thread). CORPSE IS DEFINED ON THE PARKED STAMPS, never on a bare pid re-probe: a RECYCLED pid — alive, but its native start stamp mismatching the one leg (a) parked — is corpse-equivalent because our process is dead, and the parked ABSOLUTE launch stamp is what decides pre/post-boot. Without that, the heal-then-recycle race reads 'alive ⇒ no corpse' on the next tick and walks back into the forbidden shape through a side door. Deriving is still WRONG at this site and this is NOT a swap to class (a): the census stays 8 reads / 3 classes — the site reclassifies, it does not multiply, the do-NOT-blanket-swap sentence above stands, and `shell list` still tells the truth by derivation (class (a), untouched). LOCALITY SYMMETRY (field-caught by flynn's leg-2 run, 2026-07-25): 'a shell cmd that wakes' holds for BOTH the local CLI cmd and the cross-node serve — at mint the wake arm lived in the SHELL_LINK_CMD serve handler only (module docs scoped wake-if-offline to remote cmd), so a LOCAL cmd against a corpse spooled silently and nothing woke, the exact accepted-happily/drained-by-nobody shape this req exists to kill; the arm is now the shared `linkhost::wake_if_offline_persistent`, called by both, and the derived status READ inside it is the same single census site as before (the census of 8 reads/3 classes is unchanged — the read moved, it did not multiply). ROTATION CARRIES THE DURABLE CHANNEL (flynn's frame-loss field catch, 2026-07-25, both trials): a spooled command frame is MAC-stamped under the link token current at SPOOL time, and the drain is a raw destructive passthrough — the shell verifies against its CURRENT key — so a relink's token mint orphaned every pending frame: drained to the woken binary, failed verify, correctly discarded BY THE ADAPTER, lost permanently; the wake-triggering command itself was the frame the wake lost (#23 armed the wake and never answered; #24/#19 spooled after rotation and drained in order). The fix is three-layered (todlando's A1/A2 race+crash hazards addressed at mint): (1) the token mint re-stamps all pending rows old-key→new-key (idempotent, crash-partial converges — an old-stamped remainder is converted by the next rotation or drain); (2) the rotated-out token is STASHED (`link.token.retired`, never a live credential — bind resolves only the parked file) so (3) the drain paths give any race straggler a second-chance re-stamp at delivery (`restamp_for_drain`), while frames verifying under neither key pass through untouched for the adapter to refuse exactly as before. Rows are selected by MAC verification against the threaded new key, never by token-snapshot equality (the D-2 class). MOCK CONFORMANCE IS A PROPERTY OF THE RIG, not a patch (todlando A4): mock-shell MUST verify inbound frame MACs exactly as the public contract demands of a real adapter and drop failures loudly — a mock that accepts what the field rejects is a broken rig, and that exact divergence (credulous mock) is how the frame loss passed the e2e while failing in the field. The adapter-side discard behavior is CORRECT and must never be softened to paper over the spool side. Relink additionally probes LOCALLY rather than trusting a daemon sweep, so recovery holds with the daemon down. RECOVERY PRESERVES CONSUMER STATE (the property consumers actually depend on, flynn 2026-07-25): 'same canonical id, same perch' exists so that state a consumer PERSISTED IN THE PERCH survives the recovery — an adapter's repo binding, a scanner's cursor. The teardown+spawn workaround destroyed exactly that, and its worst cost was SILENT, not the rename: alchemy's tag cursor re-baselines at the digest tip, so tags written between the kill and the re-bind are never scanned — not failed-and-retried, just never seen. A loud failure gets retried; a silent one does not. Gate: int — force-kill a bound persistent instance's process, then prove (1) `shell list` reads offline, (2) `relink` succeeds instead of SHELL_ALREADY_ONLINE and the SAME canonical id + perch survive, carrying perch-persisted consumer state with them (no teardown+spawn, no id churn, no re-baselined cursor), (3) no spontaneous relaunch occurs while the instance sits dead and undriven. FIELD VERDICT — PASS END-TO-END (flynn, alchemy-0, delivered 2026-07-26; v0.43.0, counter 77): every gate leg held in the field, on a record the pre-fix code had already poisoned. (1) `shell list` read OFFLINE while the on-disk info.json still said status=online — the daemon DERIVED offline from the corpse pid (29036 absent from the process table); the record was never corrected and did not need to be. (2) relink ADMITTED, no SHELL_ALREADY_ONLINE — verbatim SHELL_RELINKED:alchemy-0 owner=flynn pid=38644 status=offline, list online thereafter. (3) identity/state integrity: same canonical id, same owner, same perch; repo binding byte-identical (token_provenance=gh-cli); armed=true preserved; no spontaneous relaunch across the ~6.5h dead window. CURSOR SCOPING, ruled at closure (doyle 2026-07-26) — the one non-byte-identical field: the tag cursor moved 206158430541→210453397553 (gen:seq 48:333→49:49) because the recovery crossed a DAEMON restart that slid the retained digest window past the armed cursor. NOT a gap and NOT this req's property failing: spt-core raised after_predates_window and the consumer took its specced armed-cursor branch (alchemy REQ-TAG-SCANNER missed-rows leg — warn the owner, never silently re-baseline an armed cursor; alchemy src/tags.rs, two unit tests) — the FIRST FIELD FIRING of a path previously exercised only by unit tests. The 'no re-baselined cursor' gate property is hereby scoped: byte-identity holds across SHELL death within one daemon generation (the prior LEG 5 measurement, one daemon instance, uncontradicted — different scenario, generation never moved); across a daemon restart that slides the window the contract is DETECT-AND-ANNOUNCE, not preserve — corroborated independently by a second record's cursor decomposing under the same gen:seq scheme (4294967486 = 1:190). Practical exposure in this event: nil (every agent stood down through the gap; no tag traffic to miss). SECOND SPECIMEN HELD, not spent (doyle ruling 2026-07-26): liam's record — precondition verified by flynn (pid 35464 a CLEAN corpse, not recycled, so the accepted-at-mint recycled-pid caveat does not apply; same poisoned status=online shape; binding intact; cursor armed at 4294967486) — is deliberately NOT relinked while its owner is absent: the admit gate is already field-proven, a relink measurably re-baselines the cursor across a daemon-restart boundary, and liam's is the only untouched specimen with the longer (~8.5h) gap — spending it would destroy the cursor datum liam's own return produces, to buy a redundant second sample of a gate already proven to admit. It waits for liam. SPECIMEN HARVESTED (liam's own return, 2026-07-26 — operator-authorized endpoint start executed by doyle; pre-state snapshotted by doyle AND independently re-verified on disk by liam before touching anything): (1) relink ADMITTED at the ~8.5h gap — verbatim SHELL_RELINKED:alchemy-0 owner=liam pid=47608 status=offline (online at bind); the poisoned record did not refuse; info.json online is now TRUE. (2) integrity FULL PASS: id unchanged (no new mint slot), perch onlined at bind, repo binding byte-identical (token_provenance gh-cli), and the ROTATION-CARRIES-THE-DURABLE-CHANNEL machinery observed live in the field for the first time — link.token.retired present beside the fresh mint, and a post-relink round trip proven end-to-end (shell cmd spooled -> engine executed -> reply home on the owner's perch), not merely an outbound spool. (3) cursor, the sharpest datum of the harvest: BYTE-IDENTICAL through the relink itself (4294967486 armed at pid-change instant, doyle's file watch) — the relink preserves; the SCANNER moves. First scan re-baselined 1:190 -> 2:0 silently, and liam PROVED no-fire-by-precondition rather than assuming: the daemon restart bumped the generation but EVICTED NOTHING (window floor 4294967464 < cursor 4294967486, every gen-1 row past the cursor still retained), so after_predates_window is correctly false at every link of the chain (filter_after floor test -> emit-only-when-true -> unwrap_or(false)) and the missed-rows announce had no precondition to fire on. Flynn's earlier gen-bump reading is refined by this: a restart alone does not slide the window; flynn's announce fired because HIS window had genuinely slid. Scope note carried: a valid negative — the fix's announce chain verified link-by-link to contract on a specimen where it correctly stayed quiet. RESIDUE from the harvest (liam's find, alchemy lane, no core REQ): permanently-unsealable turns from a dark session are jumped by scanner cursor advance with no possible missed-rows notice (a generation bump is not a slide); ruled scanner-side announce for input-bearing null-seq jumps, pseudo-turns jump silently by design; core's per-turn input/input_seq/partial already suffice to discriminate.\"\n3193:required_stages = [\"doc\", \"impl\", \"unit\", \"int\"]  # ACTIVATED at mint (doyle 2026-07-25) — field-blocking; flynn eats id churn every alchemy release until it lands.

CORPSE IS DEFINED ON THE PARKED STAMPS, never on a bare pid re-probe: a RECYCLED pid — alive, but its native start stamp mismatching the one leg (a) parked — is corpse-equivalent because our process is dead, and the parked ABSOLUTE launch stamp is what decides pre/post-boot. Without that, the heal-then-recycle race reads 'alive ⇒ no corpse' on the next tick and walks back into the forbidden shape through a side door. Deriving is still WRONG at this site and this is NOT a swap to class (a): the census stays 8 reads / 3 classes — the site reclassifies, it does not multiply, the do-NOT-blanket-swap sentence above stands, and `shell list` still tells the truth by derivation (class (a), untouched). LOCALITY SYMMETRY (field-caught by flynn's leg-2 run, 2026-07-25): 'a shell cmd that wakes' holds for BOTH the local CLI cmd and the cross-node serve — at mint the wake arm lived in the SHELL_LINK_CMD serve handler only (module docs scoped wake-if-offline to remote cmd), so a LOCAL cmd against a corpse spooled silently and nothing woke, the exact accepted-happily/drained-by-nobody shape this req exists to kill; the arm is now the shared `linkhost::wake_if_offline_persistent`, called by both, and the derived status READ inside it is the same single census site as before (the census of 8 reads/3 classes is unchanged — the read moved, it did not multiply). ROTATION CARRIES THE DURABLE CHANNEL (flynn's frame-loss field catch, 2026-07-25, both trials): a spooled command frame is MAC-stamped under the link token current at SPOOL time, and the drain is a raw destructive passthrough — the shell verifies against its CURRENT key — so a relink's token mint orphaned every pending frame: drained to the woken binary, failed verify, correctly discarded BY THE ADAPTER, lost permanently; the wake-triggering command itself was the frame the wake lost (#23 armed the wake and never answered; #24/#19 spooled after rotation and drained in order). The fix is three-layered (todlando's A1/A2 race+crash hazards addressed at mint): (1) the token mint re-stamps all pending rows old-key→new-key (idempotent, crash-partial converges — an old-stamped remainder is converted by the next rotation or drain); (2) the rotated-out token is STASHED (`link.token.retired`, never a live credential — bind resolves only the parked file) so (3) the drain paths give any race straggler a second-chance re-stamp at delivery (`restamp_for_drain`), while frames verifying under neither key pass through untouched for the adapter to refuse exactly as before. Rows are selected by MAC verification against the threaded new key, never by token-snapshot equality (the D-2 class). MOCK CONFORMANCE IS A PROPERTY OF THE RIG, not a patch (todlando A4): mock-shell MUST verify inbound frame MACs exactly as the public contract demands of a real adapter and drop failures loudly — a mock that accepts what the field rejects is a broken rig, and that exact divergence (credulous mock) is how the frame loss passed the e2e while failing in the field. The adapter-side discard behavior is CORRECT and must never be softened to paper over the spool side. Relink additionally probes LOCALLY rather than trusting a daemon sweep, so recovery holds with the daemon down. RECOVERY PRESERVES CONSUMER STATE (the property consumers actually depend on, flynn 2026-07-25): 'same canonical id, same perch' exists so that state a consumer PERSISTED IN THE PERCH survives the recovery — an adapter's repo binding, a scanner's cursor. The teardown+spawn workaround destroyed exactly that, and its worst cost was SILENT, not the rename: alchemy's tag cursor re-baselines at the digest tip, so tags written between the kill and the re-bind are never scanned — not failed-and-retried, just never seen. A loud failure gets retried; a silent one does not. Gate: int — force-kill a bound persistent instance's process, then prove (1) `shell list` reads offline, (2) `relink` succeeds instead of SHELL_ALREADY_ONLINE and the SAME canonical id + perch survive, carrying perch-persisted consumer state with them (no teardown+spawn, no id churn, no re-baselined cursor), (3) no spontaneous relaunch occurs while the instance sits dead and undriven. FIELD VERDICT — PASS END-TO-END (flynn, alchemy-0, delivered 2026-07-26; v0.43.0, counter 77): every gate leg held in the field, on a record the pre-fix code had already poisoned. (1) `shell list` read OFFLINE while the on-disk info.json still said status=online — the daemon DERIVED offline from the corpse pid (29036 absent from the process table); the record was never corrected and did not need to be. (2) relink ADMITTED, no SHELL_ALREADY_ONLINE — verbatim SHELL_RELINKED:alchemy-0 owner=flynn pid=38644 status=offline, list online thereafter. (3) identity/state integrity: same canonical id, same owner, same perch; repo binding byte-identical (token_provenance=gh-cli); armed=true preserved; no spontaneous relaunch across the ~6.5h dead window. CURSOR SCOPING, ruled at closure (doyle 2026-07-26) — the one non-byte-identical field: the tag cursor moved 206158430541→210453397553 (gen:seq 48:333→49:49) because the recovery crossed a DAEMON restart that slid the retained digest window past the armed cursor. NOT a gap and NOT this req's property failing: spt-core raised after_predates_window and the consumer took its specced armed-cursor branch (alchemy REQ-TAG-SCANNER missed-rows leg — warn the owner, never silently re-baseline an armed cursor; alchemy src/tags.rs, two unit tests) — the FIRST FIELD FIRING of a path previously exercised only by unit tests. The 'no re-baselined cursor' gate property is hereby scoped: byte-identity holds across SHELL death within one daemon generation (the prior LEG 5 measurement, one daemon instance, uncontradicted — different scenario, generation never moved); across a daemon restart that slides the window the contract is DETECT-AND-ANNOUNCE, not preserve — corroborated independently by a second record's cursor decomposing under the same gen:seq scheme (4294967486 = 1:190). Practical exposure in this event: nil (every agent stood down through the gap; no tag traffic to miss). SECOND SPECIMEN HELD, not spent (doyle ruling 2026-07-26): liam's record — precondition verified by flynn (pid 35464 a CLEAN corpse, not recycled, so the accepted-at-mint recycled-pid caveat does not apply; same poisoned status=online shape; binding intact; cursor armed at 4294967486) — is deliberately NOT relinked while its owner is absent: the admit gate is already field-proven, a relink measurably re-baselines the cursor across a daemon-restart boundary, and liam's is the only untouched specimen with the longer (~8.5h) gap — spending it would destroy the cursor datum liam's own return produces, to buy a redundant second sample of a gate already proven to admit. It waits for liam. SPECIMEN HARVESTED (liam's own return, 2026-07-26 — operator-authorized endpoint start executed by doyle; pre-state snapshotted by doyle AND independently re-verified on disk by liam before touching anything): (1) relink ADMITTED at the ~8.5h gap — verbatim SHELL_RELINKED:alchemy-0 owner=liam pid=47608 status=offline (online at bind); the poisoned record did not refuse; info.json online is now TRUE. (2) integrity FULL PASS: id unchanged (no new mint slot), perch onlined at bind, repo binding byte-identical (token_provenance gh-cli), and the ROTATION-CARRIES-THE-DURABLE-CHANNEL machinery observed live in the field for the first time — link.token.retired present beside the fresh mint, and a post-relink round trip proven end-to-end (shell cmd spooled -> engine executed -> reply home on the owner's perch), not merely an outbound spool. (3) cursor, the sharpest datum of the harvest: BYTE-IDENTICAL through the relink itself (4294967486 armed at pid-change instant, doyle's file watch) — the relink preserves; the SCANNER moves. First scan re-baselined 1:190 -> 2:0 silently, and liam PROVED no-fire-by-precondition rather than assuming: the daemon restart bumped the generation but EVICTED NOTHING (window floor 4294967464 < cursor 4294967486, every gen-1 row past the cursor still retained), so after_predates_window is correctly false at every link of the chain (filter_after floor test -> emit-only-when-true -> unwrap_or(false)) and the missed-rows announce had no precondition to fire on. Flynn's earlier gen-bump reading is refined by this: a restart alone does not slide the window; flynn's announce fired because HIS window had genuinely slid. Scope note carried: a valid negative — the fix's announce chain verified link-by-link to contract on a specimen where it correctly stayed quiet. RESIDUE from the harvest (liam's find, alchemy lane, no core REQ): permanently-unsealable turns from a dark session are jumped by scanner cursor advance with no possible missed-rows notice (a generation bump is not a slide); ruled scanner-side announce for input-bearing null-seq jumps, pseudo-turns jump silently by design; core's per-turn input/input_seq/partial already suffice to discriminate.\"\n 3187|required_stages = [\"doc\", \"impl\", \"unit\", \"int\"]  # ACTIVATED at mint (doyle 2026-07-25) — field-blocking; flynn eats id churn every alchemy release until it lands.

Endpoints, Shells & the Instance model\n95:\n96:### 9.1 Endpoint types\n97:- **R-EP-1** Day-one types: **ReadyAgent, LiveAgent, Psyche, Worker, SptNode** (agent/infra), plus the **Shell** family and **PresenceChannel** (seams only — impl deferred). The type system is **open**.\n98:- **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.\n99:- **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.\n100:- **R-EP-4** PresenceChannel (deferred impl) is a **broker** endpoint with dispatch/bind/thread styles; presence datum `(last_active_node, last_active_endpoint, ts)`.\n101:- **R-EP-5** (deferred impl, CONTEXT \"Shell model\") **Concrete shell instantiation model:** `shell spawn` *mints* an owner-exclusive instance (`<adapter>-<n>`, distinct from the `relink`/`persistent`/`wake` online switch); permission to instantiate = shell adapter **registered on the node** (broadcast governs *discovery* only); a per-shell **`require_approval`** gate (`none`|`remembered`|`always`, default none; manifest floor, node/endpoint may tighten) reuses the consent grant store; an optional **`max_instances_per_owner`** cap (online+offline both count) with **`over_cap`** (`reject`|`approve`); instances are **aliasable** (immutable canonical id + optional perch-level alias; `adapter_name` always legible). Discovery = own instances + instantiable adapter…\n102:\n103:### 9.2 Instances (ADR-0003, as amended)\n104:- **R-INST-1** Split identity: subnet-wide **endpoint ID** vs per-node **instance**. An instance is the *same* endpoint running **natively** on a machine.\n105:- **R-INST-2** Per-node (anchored): files/project + harness session history. **Synced across instances:** the Psyche mind (two-tier — below).\n106:- **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.\n107:- **R-INST-4** Active → (dormant|suspended) fires a **transition echo commune** that syncs to the next active instance (catch-up-on-activation).\n108:- **R-INST-5** **Two-tier context sync:** live context → all instances; project context → same-project instances only. (Depends on refining Psyche authoring directives.)\n109:- **R-INST-6** Deferred messages do **not** deliver to dormant/suspended instances until active.\n110:- **R-INST-7** **Subnet registry** (eventually-consistent `endpoint_id → [instances]`) + **resolution policy** (local → most-recently-active → `id@node`) are mandatory v1 foundations.\n111:- **R-INST-8** **Remote-control** (Shell-like attach to an instance on another node; byte-stream terminal over Iroh) is a distinct mode from local operation. Handoff remote→local: `git pull` (files) + fresh-with-preload resume (mind); remote instance goes dormant, no teardown.\n112:- **R-INST-9** (M4, ADR-0006) **Multi-subnet membership:** a node may belong to **multiple subnets at once** — v1: multiple subnets of the *same user* (each its own TOTP seed/trust-context); cross-*user* membership stays deferred but is a **seam** (seed key generalizes to per-(subnet, user)). Identity is **node-global, advertised per-subnet**; the registry is **per-subnet**.\n113:- **R-INST-10** (M4, ADR-0006) **Qualified addressing:** canonical target form `[subnet:]id[@node]` (subnet- and node-qualifiers, combinable). A bare id that is **ambiguous across visible subnets refuses resolution and forces qualification** rather than guessing; within a subnet, bare ids stay unique via a **join-time collision check**.\n…\n119:\n…\n125:\n\n[Showing lines 93-113 of 229.

No work without a REQ; no REQ without intent to satisfy. The PRD holds the prose; the manifest holds the id + `required_stages`.\n12:2. **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.\n13:3. **Evidence-proximate tags, not file-tops.** A tag sits on or immediately above the real function, test, doc section, config entry, or workflow step that proves the stage. One tag = one piece of real evidence. Tags at file tops to satisfy coverage are noise and usually wrong.\n14:4. **KNOWN-HAZARDS are first-class requirements.** Each invariant is a `REQ-HAZARD-*` requiring `unit` (and `int` where cross-process/cross-node). A hazard cannot be \"covered\" without a test tagging it — the anti-regression promise becomes mechanical (PRD success criterion #6).\n15:5. **Activation, not premature failure.** Every requirement starts `required_stages = []` (inactive) so `check` stays green pre-code. A **milestone (M0–M5) activates** the requirements it delivers by setting their real `required_stages`. Deferred items (`docs/DEFERRED.md`) stay `[]` until promoted.\n16:6. **Scan roots stay honest.** `[scan].roots` includes every evidence location (`src`, `tests`, `docs`, and later `.github/workflows`, `scripts`). Audit roots whenever a new evidence dir appears — a missing root makes evidence *silently* vanish from the trace.\n17:7. **Scope at mint.** Every new `REQ-*` joins at least one `[[groups]]` subject scope in the same commit that mints it. The groups partition is what the confusion audit (Gate 4, 2026-07-30) turned into manifest structure: the `req-confusion-audit` skill scores confusability only *within* groups, so an unscoped requirement's confusable pairs go unexamined — roughly half of them, by the audit's measurement. `span-*` groups are the declared cross-scope cover for measured-hot pairs; add one when a new requirement is known to sit confusably against another scope. Do not derive scopes from id prefixes — subject matter, not spelling.\n18:\n19:### Stages\n20:\n…\n22:\n…\n41:\n\n[Showing lines 8-20 of 75.

Notifiers,\r\nrobots, lamps, game characters, sensor feeds — anything an agent should be\r\nable to command, and that might sense things back. Shells join the same\r\nnetwork as agents: addressable, discoverable, owned.\r\n\r\n## The model in five facts\r\n\r\n1. **A shell adapter declares it; instances are minted.** The\r\n   `kind = \"shell\"` [manifest](../harness-contract/manifest.md#shell-adapters-kind--shell)\r\n   declares the binary, its command vocabulary (`[shell.capabilities]`), and\r\n   its sensory vocabulary (`[shell.sensory]`). `spt shell spawn <adapter>`\r\n   mints a new instance (`notify-1`) — spawn is the creation act, not an\r\n   on/off switch; bringing an existing instance back is relink/wake.\r\n2. **The link token is the credential.** The broker mints a per-launch link\r\n   token into the spawn template; the binary binds with it\r\n   (`api bind-shell --link`), drains commands with it, emits with it. No\r\n   token, no access.\r\n3. **Commands are vocabulary-checked and durable.** `spt shell cmd notify-1\r\n   notify \"title\" \"body\"` is validated against the manifest's declared verbs\r\n   and arity before delivery — agents can't drive a shell outside its\r\n   contract. Commands are discrete and durable: they spool and a persistent\r\n   shell wakes to drain them.\r\n4. **Sensory is live-only.** `api emit` payloads reach a *live* owner\r\n   session or are dropped with a diagnostic — sensors report the present,\r\n   never the past.\r\n5. **Instantiation is governed.** Per-spawn approval\r\n   (`require_approval: none / remembered / always`), per-owner instance caps\r\n   (`max_instances_per_owner` + `over_cap`), and node-local discovery scope\r\n   (`broadcast`) are all manifest-declared floors.\r\n\r\n## Four channels between owner and shell\r\n\r\nA link can carry up to four distinct channels — each with its own delivery\r\ncontract, all keyed to the same link token:\r\n\r\n- **Command** (owner→shell, durable): the vocabulary-checked verbs above —\r\n  discrete, spooled, replayed to a waking persistent shell.\r\n- **Sensory** (shell→owner, live-only): `[shell.sensory]` emits to a live owner\r\n  or drops with a diagnostic.\r\n- **Drive** (owner→shell, ephemeral): `[shell.drive]` + `spt shell drive` — a\r\n  continuous control channel for real-time input (scroll, stick, avatar pose).\r\n  **Latest-wins, never spooled**: a newer frame supersedes an undelivered one,\r\n  and an offline shell drops the frame (no queue, no wake, no replay). Use it\r\n  for *continuous* control; use commands for *discrete, must-arrive* actions.\r\n- **Tunnel** (owner↔shell, opaque bytes): `[shell.tunnel]` + `spt shell tunnel`\r\n  — an optional reliable-ordered byte stream pair the taxonomy never\r\n  interprets (first consumer: usbip URB). Not enveloped, not framed, not\r\n  spooled; the link lifecycle governs it (a link-break closes it). Reliable\r\n  ordering means congestion surfaces as **lag, never loss** — so the tunnel is\r\n  **on-LAN only** by design (not for use across a WAN). The byte relay is\r\n  proven **same-node**; cross-node operation (on-LAN only, by the same posture)\r\n  is **not yet available** — it lands when a cross-node consumer needs it.\r\n\r\nAlongside the four channels, a link also carries two things spt-core itself\r\npushes — nothing is declared in the manifest to receive either, because they are\r\nspt-core's own frames, and they sit at **opposite ends** of the delivery\r\ntaxonomy:\r\n\r\n- the **owner's busy/idle state**. Every transition — and every (re-)link — puts\r\n  an [`activity` frame](frames.md#activity--the-owners-busyidle-state-pushed) on\r\n  the same ephemeral drain the drive channel uses, carrying the current state and\r\n  when it took effect. Drive-class like the channel it rides —\r\n  current-state-carrying, never spooled, never replayed. A shell that wants to\r\n  react to its owner going idle just reads it.\r\n- the owner session's **IO events**. What the user asked, what the agent\r\n  answered, which messages crossed, which communes landed — as discrete\r\n  [`io` frames](frames.md#io--the-sessions-io-events-durable) on the durable\r\n  spooled stream. Command-class: MAC-stamped, replayed to a binary that was\r\n  down, and each frame is its own event rather than a restatement of a state.\r\n\r\nThe durable owner→shell channels also carry free **text** and **file**\r\ntransfers (`spt shell send`). The exact wire shapes a shell binary parses —\r\nframe types, attributes, body encodings, the MAC stamp, and how a landed\r\nfile's path resolves — are specified in [the frame contract](frames.md).\r\n\r\n## Two safety properties\r\n\r\n- **Per-capability approval gates.** Beyond the per-*spawn* gate, an individual\r\n  `[shell.capabilities.<verb>]` may carry its own `require_approval` (with an\r\n  optional `class_key` scoping the grant finer than the verb — e.g. a remembered\r\n  HID-class attach never authorizes a storage-class attach). Spawn gates govern\r\n  whether an instance may *exist*; capability gates govern whether a dangerous\r\n  *act* may run.\r\n- **Ownership is owner-type-agnostic.** Any non-shell endpoint may own, spawn,\r\n  drive, command, link, and tunnel a shell — a Gateway as readily as an agent.\r\n  Control-exclusivity keys on the **owner's endpoint id**, never its type: a\r\n  different endpoint (even of the same type) cannot drive your shell.\r\n\r\nLifecycle extras: `persistent` shells auto-online with their owner;\r\n`wake_command` runs a watcher while offline (exit code 86 = wake); a shell\r\nwith `can_shutdown = true` may suspend its own owner (`api owner-shutdown`)\r\n— fail-closed otherwise.\r\n\r\nTwo lifecycle facts worth knowing before you rely on either:\r\n\r\n- **Persistent instances return after a daemon-only restart as well as a machine\r\n  reboot.** The boot sweep and each owner offline→online edge restore every\r\n  persistent instance that is down in fact while its owner is online. Launch\r\n  age and missing launch stamps do not exclude it. The birth-safe process probe\r\n  still protects a live binary, including a launch awaiting bind. Failed\r\n  launches are retried on an owner-online edge, not every reconcile tick.\r\n- **Only nonpersistent instances retain the force-kill freeze.** Their\r\n  same-boot or undatable corpses arm no watcher; cleanly closed instances and\r\n  dated pre-boot casualties remain watcher-eligible. Persistent instances\r\n  bypass this freeze. To keep a persistent shell down, use `teardown` or a\r\n  nonpersistent manifest rather than killing its process.\r\n- The daemon's `SHELL_RECORD_HEALED:<owner>/<shell_id>` diagnostics enumerate\r\n  every instance whose stale online record was corrected, not a representative\r\n  shell per owner. Already-correct records produce no repeated notice.\r\n\r\n<!-- [doc->REQ-SHELL-RELINK-FORCE] -->\r\n- **`relink` refuses an instance that is still running; `--force` is the\r\n  override.** Plain `spt shell relink <id>` is the *online switch* for an\r\n  instance that is down, so it refuses one whose binary is up. When you mean\r\n  \"stop it and start it again\" — a redeploy, a wedged binary — pass\r\n  `--force`: it runs the ordinary link-break close first (the manifest's\r\n  `pre_close` instruction, then the `close_timeout_ms` termination window,\r\n  then the authenticated kill), and only then re-spawns and links. The\r\n  canonical id, the perch and its persisted state, and the alias all survive;\r\n  teardown + spawn is what churns the id and frees the mint slot.\r\n\r\n  <!-- [doc->REQ-SHELL-RELINK-BINDING-RESULT] -->\r\n  A successful local relink reports `status=binding (online at bind)`: the\r\n  binary has launched and the bind handshake is still the online transition.\r\n  It does not describe that successful launch as `offline`.\r\n\r\n  Two things `--force` deliberately will **not** do:\r\n\r\n  - **It refuses on an `ephemeral` instance.** An ephemeral shell's close *is*\r\n    its teardown — the perch and its spool history are erased and the mint slot\r\n    freed — so there would be nothing left to restart. The refusal happens\r\n    before anything is stopped or erased. To replace such an instance, tear it\r\n    down and spawn a new one (which is a new canonical id, by design).\r\n  - **It refuses to relaunch if the binary cannot be proven stopped.** A close\r\n    can legitimately leave a process running: the force-kill authenticates its\r\n    target against the recorded pid **and** its birth stamp, and refuses rather\r\n    than fire on a recycled pid. When the pid is still held after the close,\r\n    `--force` reports it (naming the pid and what could be proven about it)\r\n    instead of launching a second binary for one instance — the second one\r\n    would be unreachable through the retired link token and invisible to the\r\n    record. The link *is* closed at that point, so the instance is offline and\r\n    re-linkable as soon as that process is gone.\r\n\r\n  Cross-node (`<ref>@<node>`) the flag rides as an argument of the existing\r\n  relink action, so no wire version moves — but a node running an spt that\r\n  predates the flag ignores it and answers \"already online\". That reply is\r\n  reported as a **failure** (`SHELL_REMOTE_FORCE_UNHONORED`), never as success:\r\n  under `--force` \"it was already up\" is precisely the thing that did not\r\n  happen.\r\n\r\n## Teach the agent about your shell: `[[hints]]`\r\n\r\n<!-- [doc->REQ-SHELL-HINTS] -->\r\n\r\nA shell adapter can declare `[[hints]]` exactly like a harness adapter — it is a\r\ntop-level manifest section, not a harness-only one:\r\n\r\n```toml\r\n[[hints]]\r\nkeywords = [\"screenshot\", \"what's on screen\"]\r\ntext = \"the PACER shell can capture a window: `spt shell cmd PACER-0 capture <window>`\"\r\n```\r\n\r\nEach hint fires **once per session**, and your adapter contributes **at most one\r\nline per message** (the per-source cap — the harness gets one, and so does every\r\nother shell adapter, so a second shell can never be silenced by a chatty first).\r\nWhich line the agent sees depends on **instantiation, never on link state**:\r\n\r\n- the owner **holds an instance** of your adapter → the **full** hint text,\r\n  whether that instance is online or offline;\r\n- the owner holds **no instance** → a **teaser** naming the keyword that fired\r\n  and the command that shows the text: `spt adapter hints <adapter>`.\r\n\r\nThat command is also how you read your own hints back:\r\n\r\n```console\r\n$ spt adapter hints spt-shell-notify\r\n[screenshot, what's on screen] the PACER shell can capture a window: …\r\n```\r\n\r\nIt resolves the merged view, so a profile's `[[hints]]` overlay is what prints —\r\nand it prints nothing (exit 0) for an adapter that declares none.\r\n\r\n### How a keyword matches\r\n\r\n<!-- [doc->REQ-MANIFEST-4] -->\r\n\r\nBy default, each keyword is a **case-insensitive substring**: there are no word\r\nboundaries, whitespace is literal, and symbols match as written with no escaping.\r\n\r\nSet `regex = true` on a `[[hints]]` row to compile its keywords as regular\r\nexpressions. Regex matching is **case-sensitive** unless the pattern uses\r\n`(?i)`. An **invalid regex matches nothing** — it silences its own hint and never\r\npanics.\r\n\r\nFor word boundaries around a phrase:\r\n\r\n```toml\r\n[[hints]]\r\nkeywords = ['\\bpair machine\\b']\r\nregex = true\r\ntext = \"Pair the machine before sending it work.\"\r\n```\r\n\r\nWith `regex = true`, use `keywords = ['(?i)\\bsweep\\b']` for a case-insensitive\r\nwhole word, or `keywords = ['pair\\s+machine']` to allow one or more whitespace\r\ncharacters between the words.\r\n\r\n## Start here\r\n\r\n[Getting started: a notification shell](getting-started.md) — install the\r\nshipping `spt-shell-notify` adapter, drive a native toast from an agent, and\r\ncopy its manifest for your own surface.\r\n","newText":"# Shells\r\n\r\nA **shell** is the non-agent endpoint kind: a *driven surface*.

That reply is\r\n  reported as a **failure** (`SHELL_REMOTE_FORCE_UNHONORED`), never as success:\r\n  under `--force` \"it was already up\" is precisely the thing that did not\r\n  happen.\r\n\r\n## Teach the agent about your shell: `[[hints]]`\r\n\r\n<!-- [doc->REQ-SHELL-HINTS] -->\r\n\r\nA shell adapter can declare `[[hints]]` exactly like a harness adapter — it is a\r\ntop-level manifest section, not a harness-only one:\r\n\r\n```toml\r\n[[hints]]\r\nkeywords = [\"screenshot\", \"what's on screen\"]\r\ntext = \"the PACER shell can capture a window: `spt shell cmd PACER-0 capture <window>`\"\r\n```\r\n\r\nEach hint fires **once per session**, and your adapter contributes **at most one\r\nline per message** (the per-source cap — the harness gets one, and so does every\r\nother shell adapter, so a second shell can never be silenced by a chatty first).\r\nWhich line the agent sees depends on **instantiation, never on link state**:\r\n\r\n- the owner **holds an instance** of your adapter → the **full** hint text,\r\n  whether that instance is online or offline;\r\n- the owner holds **no instance** → a **teaser** naming the keyword that fired\r\n  and the command that shows the text: `spt adapter hints <adapter>`.\r\n\r\nThat command is also how you read your own hints back:\r\n\r\n```console\r\n$ spt adapter hints spt-shell-notify\r\n[screenshot, what's on screen] the PACER shell can capture a window: …\r\n```\r\n\r\nIt resolves the merged view, so a profile's `[[hints]]` overlay is what prints —\r\nand it prints nothing (exit 0) for an adapter that declares none.\r\n\r\n### How a keyword matches\r\n\r\n<!-- [doc->REQ-MANIFEST-4] -->\r\n\r\nBy default, each keyword is a **case-insensitive substring**: there are no word\r\nboundaries, whitespace is literal, and symbols match as written with no escaping.\r\n\r\nSet `regex = true` on a `[[hints]]` row to compile its keywords as regular\r\nexpressions. Regex matching is **case-sensitive** unless the pattern uses\r\n`(?i)`. An **invalid regex matches nothing** — it silences its own hint and never\r\npanics.\r\n\r\nFor word boundaries around a phrase:\r\n\r\n```toml\r\n[[hints]]\r\nkeywords = ['\\bpair machine\\b']\r\nregex = true\r\ntext = \"Pair the machine before sending it work.\"\r\n```\r\n\r\nWith `regex = true`, use `keywords = ['(?i)\\bsweep\\b']` for a case-insensitive\r\nwhole word, or `keywords = ['pair\\s+machine']` to allow one or more whitespace\r\ncharacters between the words.\r\n\r\n## Start here\r\n\r\n[Getting started: a notification shell](getting-started.md) — install the\r\nshipping `spt-shell-notify` adapter, drive a native toast from an agent, and\r\ncopy its manifest for your own surface.\r\n"},{"path":"C:\\Users\\decid\\Documents\\projects\\spt-core\\.worktrees\\287-shellrestore\\traceable-reqs.toml","diff":" 4403|name = \"cli-output-surface\"\n 4404|requirements = [\n+4405|  \"REQ-SHELL-RELINK-BINDING-RESULT\",\n 4405|  \"REQ-BIND-HONEST-SELF-STAMP\",\n 4406|  \"REQ-CLI-1\",\n\n 4448|]\n\n 4567|name = \"endpoint-presence-truth\"\n 4568|requirements = [\n+4570|  \"REQ-SHELL-HEAL-ENUMERATION\",\n 4569|  \"REQ-CONN-POISON-ATTRIBUTION\",\n 4570|  \"REQ-DAEMON-5\",\n\n 4632|]","firstChangedLine":4404,"op":"update","snapshotsPruned":true}]},"isError":false,"timestamp":1788999924280}}
