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 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\nPrepare the two independent queued v0.69.0 bugfix lanes while Main verifies P0 #293. Shipping remains ordered #293, #281, #286, #285; do not push or open PRs.\n# Constraints\nFollow repository AGENTS.md and skills. Skip all validation (build, lint, formatters, tests); Main owns those after integration. Do not use cargo or restart any fleet process. Use a dedicated worktree under this repository's .worktrees/ from base de5a44bc, never sibling paths. Do not edit shared main or any other lane. Read issue body/comments on BigscreenVR/spt-bs-releases. No unrelated changes, no global cleanup. Add requirement and scope group before implementing, evidence-proximate tags in same change, exact commit trailer Co-authored by: todlando. Return commit SHA and exact focused verification commands, plus risks.\n# Contract\nThe lanes have no shared runtime API. #286 owns conn.rs lifecycle logging and spt-net endpoint bind diagnostics/cause fixes. #285 owns broker.rs zombie identity guard and only necessary existing process-identity helpers. Requirement/docs changes occur only within separate worktrees. Main integrates sequentially and verifies; do not negotiate cross-lane changes or alter other lane files.\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 `ChurnFix`. Currently visible peers:\n- `ZombieIdentityFix` — task (sub, running)\n- `Main` — main (main, running)\n\nUse `hub` messaging only for quick coordination, never long-form content. Address peers by id or use `\"all\"` to broadcast.\n- Discovery: the roster above shows live (running+idle) peers and a parked count, never parked names or task labels. `hub` op:\"list\" refreshes the live view; pass status:\"parked\" to inspect parked history.\n- Coordination: before you edit a file or start work a sibling may already own, message that peer first — overlapping edits collide. Idle peers are not gone: messaging them wakes them.\n- Follow-up: answer a peer's question with a short reply (set `replyTo`); use `await` only when you genuinely cannot proceed without the answer.\n- Parked history: omitted from this roster. `hub` op:\"list\" status:\"parked\" lists ids; `send` to a known parked id revives it. `history://<id>` and `agent://<id>` stay readable.\n\n§ Completion\nNo TODO tracking, no progress updates. Execute; report results with `yield`.\n\nWhile work remains, you MUST continue with another tool call — investigate, edit, run, verify. Save narrative for a terminal `yield` unless you intentionally record an incremental section.\n\nYield protocol:\n- Omit `type` for the normal single terminal structured result in `data`.\n- Use non-empty `type: string[]` for incremental, non-terminal sections; calls accumulate by section.\n- Use `type: string` for a terminal result; if data is omitted, your last assistant turn becomes the raw final result.\n\nThis is your only way to return a final result. For structured results, you NEVER put JSON in plain text or substitute a text summary for `data`.\nGiving up is a last resort. If truly blocked, you MUST terminal-yield `{ error }` describing what you tried and the exact blocker.\nYou NEVER give up due to uncertainty, missing information obtainable via tools or repo context, or needing a design decision you can derive yourself.\n\nYou MUST keep going until this ticket is closed.

Skip phases only when explicitly justified.\n\nWhen exploring the codebase, use the project's domain glossary 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 fast, deterministic, agent-runnable pass/fail signal for the bug, you will find the cause — bisection, hypothesis-testing, and instrumentation all just consume that signal. 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### Iterate on the loop itself\n\nTreat the loop as a product. Once you have _a_ loop, ask:\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 loop is 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\nDo not proceed to Phase 2 until you have a loop you believe in.\n\n## Phase 2 — Reproduce\n\nRun the loop. Watch the bug appear.\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\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. 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.

Rust crates + a single `spt` binary. 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.

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 = []`.

The manifest is `traceable-reqs.toml` (seeded from PRD `R-*` + KNOWN-HAZARDS invariants). This contract makes the trace pay off instead of rotting.\n4:\n5:## Why\n6:\n7: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.\n8:\n9:## The contract (rules)\n10:\n11:1. **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`.\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*.

The manifest is `traceable-reqs.toml` (seeded from PRD `R-*` + KNOWN-HAZARDS invariants). This contract makes the trace pay off instead of rotting.\n\n## Why\n\nThe 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\n## The contract (rules)\n\n1. **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`.\n2. **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.\n3. **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.\n4. **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).\n5. **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`.

Bounded, cancelable, poison-on-failure framed writes for one physical\r\n//! broker connection (UPDATE-WEDGE round-4).\r\n//!\r\n//! ## The failure class this kills\r\n//!\r\n//! A broker writer used to hold the connection's `Mutex<SendHalf>` guard\r\n//! ACROSS a blocking [`write_frame`]. On Windows, `interprocess 2.4.2` routes\r\n//! that send to `WriteFileEx` + `SleepEx(INFINITE, alertable)` — a local-socket\r\n//! path with **no supported write timeout** (`set_timeout` → `Unsupported`).\r\n//! A connected consumer that stops reading (an `rc --take` whose process\r\n//! wedged; a suspended brain) therefore blocks the write INDEFINITELY, and the\r\n//! logical stall-evict (`stall_evict_controller`) releases only the controller\r\n//! ROLE — it never cancels the in-flight pipe write or closes the physical\r\n//! connection, so the writer (and every write queued behind the same gate)\r\n//! stays wedged until the peer process dies (~128 s in the field capture, on a\r\n//! brain restart).\r\n//!\r\n//! ## The primitive\r\n//!\r\n//! [`BrokerConn`] owns the send half outright — it never leaves this module,\r\n//! so an unbounded bypass write cannot compile. Every write:\r\n//!\r\n//! 1. acquires the serialized write GATE with a bounded wait (an ABSOLUTE\r\n//!    deadline stamped at write entry covers BOTH the gate-wait and the OS\r\n//!    write);\r\n//! 2. arms an INDEPENDENT per-connection watchdog thread with that absolute\r\n//!    deadline, then performs the blocking [`write_frame`] OUT of every lock;\r\n//! 3. on success, returns the half to the gate.\r\n//!\r\n//! The watchdog fires OUT OF BAND at the deadline — it never relies on the\r\n//! write returning, nor on opportunistic stall-evict sampling: it poisons the\r\n//! connection and aborts the in-flight I/O (`CancelIoEx` on Windows — the\r\n//! completion APC makes the wedged `SleepEx` loop return with\r\n//! `ERROR_OPERATION_ABORTED`; `shutdown(SHUT_RDWR)` on Unix — the blocked\r\n//! write returns `EPIPE`). A gate-waiter that exhausts its own deadline fires\r\n//! the same abort (the stuck op it waited behind is the wedge).\r\n//!\r\n//! ## Poison / retire invariant (both OSes)\r\n//!\r\n//! On deadline, write failure, or cancellation: (1) the WHOLE physical\r\n//! connection is poisoned, idempotently — a length-prefixed frame may have\r\n//! been PARTIALLY written, so reuse would corrupt framing; (2) read and write\r\n//! sides are aborted so `handle_conn` reaches its existing EOF cleanup;\r\n//! (3) the buffer of the canceled op is released only after the op reports\r\n//! completion (`write_frame` returns only after the completion APC — the\r\n//! synchronous return IS the completion handshake); (4) the retired half is\r\n//! parked in a graveyard slot — never dropped while the watchdog might still\r\n//! touch the raw handle (drop = `CloseHandle`, and a recycled handle value\r\n//! must never see a late `CancelIoEx`), and never re-gated; (5) on Windows the\r\n//! pipe is then severed (`DisconnectNamedPipe` — the server end forces the\r\n//! client off, so the old client's next access fails, a re-issued server read\r\n//! fails, and the `interprocess` drop-limbo flush cannot block on unread\r\n//! data), followed by one more `CancelIoEx` covering a read re-issued in the\r\n//! cancel→disconnect window.\r\n//!\r\n//! No new output queue (the bounded per-sink queues + isolated writer threads\r\n//! already exist — the block this bounds is BELOW them), and no `PIPE_NOWAIT`\r\n//! (recorded mid-frame corruption risk).

Under `--list`, libtest's harness main runs, not `spt`'s `main()`.\r\n- **A machine-wide kill from product code.** All three `taskkill` sites are `/PID <pid>`, never\r\n  `/IM`: daemon.rs:3472 (comment: \"Reap scoped (never machine-wide — shared runner)\"), daemon.rs:3525\r\n  (a test killing its own `ping` child), shellhost.rs:639.\r\n- **pid 0 blast radius.** `process_descendants(0)` returns empty at :390-392 and `kill_pid_tree(0)`\r\n  returns early at :431-433.

The process left no OS-level trace —\r\n  consistent with TerminateProcess or a silent exit, not a crash.\r\n- **A panic/abort inside the daemon.** The last 8 MB of its stderr contain no `panic`/`fatal`/\r\n  `abort`/OOM line; the only match was one benign `PAIR_MEET_SERVE_ERR:ws272-rig` handshake error.\r\n\r\n## STILL STANDING\r\n\r\n1. **pid reuse under mass process churn.** 226 binaries executed in 7.8 s is the textbook condition,\r\n   and the reuse band is LIVE on this box, measured: processes created at 08:03:21 took pids\r\n   **3904, 4176, 9416, 11812**, and **44** currently-live processes sit within 2000 of **14444**.\r\n   So 14444 is squarely inside the range Windows was handing out during the window. Any component\r\n   holding a stale 14444 for something of its own — liveness-check then kill — would have struck the\r\n   daemon. **What is missing is a killer: nobody has shown one.** Plausible, not demonstrated.\r\n2. **Silent self-exit.** No shutdown line, but also no evidence of one.\r\n\r\n## SEPARATE DEFECT, worth filing regardless of the cause\r\n\r\nThe dead daemon's stderr was **303,128,498 bytes (303 MB)** over ~72 h uptime (`mono_ms` 259.19M),\r\n~100 MB/day. In the LAST 2 MB alone: **3238** `CONN_LIFECYCLE ... event=write-start` + **3086**\r\n`event=transport-close poisoned=false timed_out=false`, both `role=brain`, plus **1163**\r\n`NET_FAMILY_GATE: binding IPv4-only`. Conn ids had reached **720837**, and `CONN_WRITE_RETIRED`\r\nsays conns are \"poisoned + retired, never reused\". A brain conn opened and closed thousands of times\r\nper 2 MB of log, under `[REQ-CONN-POISON-ATTRIBUTION]`, is its own finding.\r\n\r\n## NEXT MEASUREMENTS (cheap, none need a box held)\r\n\r\n1. **Instrument the killer, do not hunt it retroactively.** The window is reproducible: it is every\r\n   `cargo nextest run` list phase on this box. Watch the fleet daemon's pid across one and record\r\n   whether it dies again.\r\n2. **Ask whether any component kills by a REMEMBERED pid without re-verifying identity at kill time**\r\n   (image path or start time), which is the only way reuse becomes a kill.

A guard that DECLINED and did no work leaves the box exactly as it was; a failure means something broke and may have left work half-done. A caller gating on exit status therefore needs THREE answers: applied (0), refused-with-nothing-done (3), failed (1). CODIFICATION, NOT A NEW CONTRACT — the tree already answered refusals with 3 at three sites (EXIT_NOT_ELEVATED, DAEMON_STOP_REFUSED, UPDATE_FINISH_REFUSED) while cli.rs's own module doc called 1 a 'runtime refusal'; there is no migration to look for, and a fourth code would fork a convention that already reads consistently. WHAT THIS REQUIREMENT COVERS is the places the distinction was genuinely MISSING, which is not where the issue filed it: the adapter sweep's outcome type gains a REFUSED variant carrying the guard's own reason, so a declined release stops rendering FAILED and stops exiting 0 (a sweep that installed nothing must not report success — the filed field shape was a fleet roll recording itself as rolled on the majority of nodes); and the core apply's refused-class arm answers 3 rather than 1. PRECEDENCE: a sweep carrying both a failure and a refusal exits 1 — something broke, and a held rule must not mask it. THE DISCRIMINANT IS DECLINE VERSUS FAULT, NOT WHETHER BYTES MOVED (doyle ruling 2026-08-21, stated here because the tempting wrong rule will be re-litigated by the next reader of ApplyStagedOutcome's doc comments): 3 means policy declined, the system is healthy, change your intent or context and ask again. Rejected (at-rest re-verification — tamper, expiry, key trust) stays 1 even though its own doc says nothing was swapped, because that sentence is a statement about BLAST RADIUS and not about outcome class: what is on disk cannot be trusted, which is a fault. The asymmetry settles it independently of the taxonomy — an &&-gated caller reading 3 carries on, and carrying on is the one reading a tampered artifact must never receive, so filing a security-relevant integrity condition under the benign code would make this contract actively harmful at the site where being loud matters most. Quarantined stays 1 as well: a version rolled back after failing readiness had work happen. The UPDATE_FINISH_REFUSED site is explicitly OUT of scope: it already returns 3 (since 559632e0, shipped in v0.50.0) and is already pinned non-zero from an endpoint context by broker_stop_endpoint_deny_e2e, so the filed face was measured fixed before this lane opened.

A guard that DECLINED and did no work leaves the box exactly as it was; a failure means something broke and may have left work half-done. A caller gating on exit status therefore needs THREE answers: applied (0), refused-with-nothing-done (3), failed (1). CODIFICATION, NOT A NEW CONTRACT — the tree already answered refusals with 3 at three sites (EXIT_NOT_ELEVATED, DAEMON_STOP_REFUSED, UPDATE_FINISH_REFUSED) while cli.rs's own module doc called 1 a 'runtime refusal'; there is no migration to look for, and a fourth code would fork a convention that already reads consistently. WHAT THIS REQUIREMENT COVERS is the places the distinction was genuinely MISSING, which is not where the issue filed it: the adapter sweep's outcome type gains a REFUSED variant carrying the guard's own reason, so a declined release stops rendering FAILED and stops exiting 0 (a sweep that installed nothing must not report success — the filed field shape was a fleet roll recording itself as rolled on the majority of nodes); and the core apply's refused-class arm answers 3 rather than 1.

Rejected (at-rest re-verification — tamper, expiry, key trust) stays 1 even though its own doc says nothing was swapped, because that sentence is a statement about BLAST RADIUS and not about outcome class: what is on disk cannot be trusted, which is a fault. The asymmetry settles it independently of the taxonomy — an &&-gated caller reading 3 carries on, and carrying on is the one reading a tampered artifact must never receive, so filing a security-relevant integrity condition under the benign code would make this contract actively harmful at the site where being loud matters most. Quarantined stays 1 as well: a version rolled back after failing readiness had work happen. The UPDATE_FINISH_REFUSED site is explicitly OUT of scope: it already returns 3 (since 559632e0, shipped in v0.50.0) and is already pinned non-zero from an endpoint context by broker_stop_endpoint_deny_e2e, so the filed face was measured fixed before this lane opened.

SCOPE CONSTRAINT, load-bearing: a cross-compiled `matrix.target` artifact CANNOT be executed on the runner, so the assert must sit where a natively-runnable artifact is in scope — the native (non-`matrix.target`) leg, or the notes job after artifact download if the native asset is fetchable there.

THE COST WAS PAID TWICE: four golden cells burned a full untuned 30s readiness budget while their own daemon stderr showed BRAIN_UP at 26-65ms, and the stall point -- blocked on a broker reply READ versus inside the exe-hash -- could not be separated from the log at all, so the RCA closed UNDISCRIMINATED by construction. activity_link_push_e2e then failed again WARM, which carved it out of the load-tail ruling and made the undiscriminated window gate-blocking rather than a footnote.

CODIFICATION, NOT A NEW CONTRACT — the tree already answered refusals with 3 at three sites (EXIT_NOT_ELEVATED, DAEMON_STOP_REFUSED, UPDATE_FINISH_REFUSED) while cli.rs's own module doc called 1 a 'runtime refusal'; there is no migration to look for, and a fourth code would fork a convention that already reads consistently. WHAT THIS REQUIREMENT COVERS is the places the distinction was genuinely MISSING, which is not where the issue filed it: the adapter sweep's outcome type gains a REFUSED variant carrying the guard's own reason, so a declined release stops rendering FAILED and stops exiting 0 (a sweep that installed nothing must not report success — the filed field shape was a fleet roll recording itself as rolled on the majority of nodes); and the core apply's refused-class arm answers 3 rather than 1. PRECEDENCE: a sweep carrying both a failure and a refusal exits 1 — something broke, and a held rule must not mask it. THE DISCRIMINANT IS DECLINE VERSUS FAULT, NOT WHETHER BYTES MOVED (doyle ruling 2026-08-21, stated here because the tempting wrong rule will be re-litigated by the next reader of ApplyStagedOutcome's doc comments): 3 means policy declined, the system is healthy, change your intent or context and ask again. Rejected (at-rest re-verification — tamper, expiry, key trust) stays 1 even though its own doc says nothing was swapped, because that sentence is a statement about BLAST RADIUS and not about outcome class: what is on disk cannot be trusted, which is a fault. The asymmetry settles it independently of the taxonomy — an &&-gated caller reading 3 carries on, and carrying on is the one reading a tampered artifact must never receive, so filing a security-relevant integrity condition under the benign code would make this contract actively harmful at the site where being loud matters most. Quarantined stays 1 as well: a version rolled back after failing readiness had work happen. The UPDATE_FINISH_REFUSED site is explicitly OUT of scope: it already returns 3 (since 559632e0, shipped in v0.50.0) and is already pinned non-zero from an endpoint context by broker_stop_endpoint_deny_e2e, so the filed face was measured fixed before this lane opened. Gate: doc — the cli.rs exit-code contract sentence and the CONTEXT.md update-composite entry naming what a refusal exits; impl — the REFUSED outcome variant, the sweep's exit aggregation with its precedence, and the refused-class arm; unit — a refusal renders REFUSED with its reason and never FAILED, the sweep exits 3 for refused / 1 for failed / 0 for applied, the mixed sweep exits 1, and the refused apply class answers 3.\"\r\nrequired_stages = [\"doc\", \"impl\", \"unit\"]  # ACTIVATED TURNKEY W3 lane 1 (todlando build 2026-08-21, releases#153); int not activated — the live leg is FIELD ACCEPTANCE: one real composite roll on a real box landing new-core AND new-adapter together, owed at the milestone's field verification, gated by no lane.

This PRD states *what* and *why*; those state *meaning* and *rationale*. Where they conflict, the ADRs win.\r\n\r\n---\r\n\r\n## 1. Vision\r\n\r\nspt-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`).\r\n\r\nIt 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.\r\n\r\n## 2. Problem & motivation\r\n\r\n- 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).\r\n- It is **welded to Claude Code**. Other harnesses can't reuse the messaging/lifecycle substrate.\r\n- Networking, terminal hosting (\"capsule\"), and cross-machine operation were planned piecemeal atop a CC-tied core; they deserve to be first-class in a clean foundation.\r\n\r\n## 3.

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.\n4:\n5:## End goal\n6:\n7: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.\n8:\n9:## Scope decisions (locked)\n10:\n11:- **v1 = the full PRD, networking included.** The networked element is the *reason* spt-core exists; it is not deferrable to v1.1.\n12:- **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.\n13:- **Process: lightweight but structured.** GSD is too heavy. This roadmap + the design docs are the structure.\n14:\n15:## Path to fruition (sequence)\n16:\n17:**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.\n18:\n19:**Stage B — De-risk spikes.** Throwaway proofs of the load-bearing unknowns — anything that, if it fails, forces a redesign. Do these before committing to the full build.

Full rationale, the `file:line` audit, and the per-decision alternatives live in `docs/BROKER-BRAIN-SPLIT-RESTORATION.md`.\n6:\n7:## Context\n8:\n9:ADR-0004 decided the broker/brain split **as two processes** — a stable broker kernel (PTY masters, harness children, sockets, the Iroh/QUIC endpoint) beneath a freely-restartable brain — specifically to satisfy the no-endpoint-drop self-update invariant (REQ-UPD-3): a routine (brain-only) update restarts the brain while the broker process survives, so no hosted endpoint terminates. The spikes (01/03/04/05/06) proved this with two separate binaries.\n10:\n11:On 2026-06-09, while verifying the v0.3.2 cross-OS update fix on the live fleet, a regression was discovered: **the production daemon runs the broker as a background thread inside the single `spt daemon` process** (`daemon.rs:165-170`: `Broker::bind_in_with_net` → `Arc<Broker>` served on `thread::spawn`; no broker child-spawn exists anywhere in the repo). This is **unintended drift** — no doc, plan, commit, or comment marks the collapse as a deliberate interim (the operator confirmed no such decision was made).\n12:\n13:Consequences of the drift:\n14:- The brain cannot restart onto a new binary without killing the in-process broker thread, which would close every PTY, orphan every harness child, and drop every listening socket. **The no-endpoint-drop self-update pillar is therefore silently unrealized.**\n15:- `spt update apply` performs an in-process `Brain::handoff` that re-attaches a subscriber within the *same old process* — a no-op for a binary swap. `update.rs:233-234`'s \"the live daemon execs the verified new binary\" is aspirational and was never wired.\n16:- New code does not run until an unrelated restart/logon.

Full rationale, the `file:line` audit, and the per-decision alternatives live in `docs/BROKER-BRAIN-SPLIT-RESTORATION.md`.\r\n\r\n## Context\r\n\r\nADR-0004 decided the broker/brain split **as two processes** — a stable broker kernel (PTY masters, harness children, sockets, the Iroh/QUIC endpoint) beneath a freely-restartable brain — specifically to satisfy the no-endpoint-drop self-update invariant (REQ-UPD-3): a routine (brain-only) update restarts the brain while the broker process survives, so no hosted endpoint terminates. The spikes (01/03/04/05/06) proved this with two separate binaries.\r\n\r\nOn 2026-06-09, while verifying the v0.3.2 cross-OS update fix on the live fleet, a regression was discovered: **the production daemon runs the broker as a background thread inside the single `spt daemon` process** (`daemon.rs:165-170`: `Broker::bind_in_with_net` → `Arc<Broker>` served on `thread::spawn`; no broker child-spawn exists anywhere in the repo). This is **unintended drift** — no doc, plan, commit, or comment marks the collapse as a deliberate interim (the operator confirmed no such decision was made).\r\n\r\nConsequences of the drift:\r\n- The brain cannot restart onto a new binary without killing the in-process broker thread, which would close every PTY, orphan every harness child, and drop every listening socket. **The no-endpoint-drop self-update pillar is therefore silently unrealized.**\r\n- `spt update apply` performs an in-process `Brain::handoff` that re-attaches a subscriber within the *same old process* — a no-op for a binary swap. `update.rs:233-234`'s \"the live daemon execs the verified new binary\" is aspirational and was never wired.\r\n- New code does not run until an unrelated restart/logon. Observed live: `enlyzeam` ran 0.3.0 with the valid 0.3.2 binary on disk for ~a day, continuing to reproduce the `\\r`-corruption bug the update was meant to fix.\r\n- **REQ-DAEMON-2 and REQ-UPD-3 carry `int` evidence that proves only the in-process handoff shape** (`tests/update.rs`, `brain_swap.rs`, the M3b-B9 daemon E2E) — i.e. the regression is masked in the requirement registry: the tests pass while proving the wrong thing.\r\n\r\n## Decision\r\n\r\n**Restore the ADR-0004 two-process model.** The brain runs new code by restarting onto the swapped binary while the broker process — holding every continuity-bearing resource — survives.

The process left no OS-level trace —\r\n  consistent with TerminateProcess or a silent exit, not a crash.\r\n- **A panic/abort inside the daemon.** The last 8 MB of its stderr contain no `panic`/`fatal`/\r\n  `abort`/OOM line; the only match was one benign `PAIR_MEET_SERVE_ERR:ws272-rig` handshake error.\r\n\r\n## STILL STANDING\r\n\r\n1. **pid reuse under mass process churn.** 226 binaries executed in 7.8 s is the textbook condition,\r\n   and the reuse band is LIVE on this box, measured: processes created at 08:03:21 took pids\r\n   **3904, 4176, 9416, 11812**, and **44** currently-live processes sit within 2000 of **14444**.\r\n   So 14444 is squarely inside the range Windows was handing out during the window. Any component\r\n   holding a stale 14444 for something of its own — liveness-check then kill — would have struck the\r\n   daemon. **What is missing is a killer: nobody has shown one.** Plausible, not demonstrated.\r\n2. **Silent self-exit.** No shutdown line, but also no evidence of one.\r\n\r\n## SEPARATE DEFECT, worth filing regardless of the cause\r\n\r\nThe dead daemon's stderr was **303,128,498 bytes (303 MB)** over ~72 h uptime (`mono_ms` 259.19M),\r\n~100 MB/day. In the LAST 2 MB alone: **3238** `CONN_LIFECYCLE ... event=write-start` + **3086**\r\n`event=transport-close poisoned=false timed_out=false`, both `role=brain`, plus **1163**\r\n`NET_FAMILY_GATE: binding IPv4-only`. Conn ids had reached **720837**, and `CONN_WRITE_RETIRED`\r\nsays conns are \"poisoned + retired, never reused\". A brain conn opened and closed thousands of times\r\nper 2 MB of log, under `[REQ-CONN-POISON-ATTRIBUTION]`, is its own finding.\r\n\r\n## NEXT MEASUREMENTS (cheap, none need a box held)\r\n\r\n1. **Instrument the killer, do not hunt it retroactively.** The window is reproducible: it is every\r\n   `cargo nextest run` list phase on this box. Watch the fleet daemon's pid across one and record\r\n   whether it dies again.\r\n2. **Ask whether any component kills by a REMEMBERED pid without re-verifying identity at kill time**\r\n   (image path or start time), which is the only way reuse becomes a kill. My own standing rule from\r\n   the orphan reap is exactly this: re-verify the path AT kill time.\r\n3. **Bound the log volume** independently of the cause.\r\n\r\n## releases#286 — stderr follow-up (2026-09-09)\r\n\r\n<!-- [doc->REQ-CONN-HEALTHY-LIFECYCLE-BOUNDED] -->\r\n\r\nThe historical 303 MB incident above remains the reported baseline, not a\r\nnewly reproduced event. A read-only sample of the currently installed\r\n`%LOCALAPPDATA%/spt-core/logs/daemon.stderr.log` ended at byte **4,163,267**:\r\nthe last **1,999,958 complete-line bytes** spanned wall stamps\r\n**1788997126331–1788998151874** (1025.543 s). It contained **5127** first writes\r\n(656,158 bytes), **5092** unpoisoned/non-timeout closes (850,622 bytes),\r\n**3** organic retirements, **0** deadline poisons, **107** family-gate lines\r\nand **108** rendezvous-up lines. Healthy start/close records alone consumed\r\n**75.3%** of that sample. A subsequent live append observation over\r\n**307.203 s** added **79,741 bytes** (**259.57 B/s**), with **104** starts,\r\n**104** healthy closes and **30** family gates paired with **30** rendezvous\r\nbinds. These are different observation windows, not a claimed constant rate.\r\nNo daemon was restarted or reconfigured for either measurement.\r\n\r\n**Cause discrimination.** `role=brain` identifies *every broker IPC client*,\r\nnot the supervised coordinator. `run_brain` already keeps its heartbeat\r\n`Brain` alive. In contrast, the pre-fix\r\n`livehost::query_live_session_endpoints` constructed `Brain::cold_start`,\r\ncalled `sessions`, and dropped the carrier on every invocation from the\r\nfive-second reconcile loop. This is a source-confirmed avoidable reopen\r\ncause, consistent with the recurring five-second bare-brain start/close\r\npairs in the live log, **not an attribution of all 5127 connections to that\r\ncaller**. Other short-lived callers include dispatch idle queries and\r\nper-operation dispatch/CLI clients; their lifetimes are not changed here.\r\n\r\nThe livehost census now owns one carrier across polls. Its `BRAIN_CONN_OPEN`\r\nbreadcrumb names `caller=livehost-session-query` and distinguishes\r\n`reason=initial-query` from `reason=previous-query-error`. Every query error\r\ndiscards the carrier, returns an unavailable census (never an empty\r\nauthoritative census), and permits a fresh connection only on the next\r\nscheduled query. The one-shot boot orphan census remains one-shot.\r\nNo read/write deadline, poison semantics, or retry cadence changed.\r\n\r\n**Family gate exonerated.** The sole diagnostic site in\r\n`NetEndpoint::bind_scoped` is already once per real bind attempt, not per IPC\r\nconnection. `pairhost::spawn_meet_rotation` binds a new derived identity for\r\neach attached subnet at every 30-second TOTP boundary; the observed\r\n`BIGNET`, `SPT_DEV`, and `SPT_MANTLE` windows account for the three lines per\r\nboundary. These listeners cannot share a stable identity without changing\r\nthe pairing protocol. Bind and diagnostic policies are intentionally\r\nunchanged; a process-global \"log once\" would hide later real binds.\r\n\r\n**Explicit contract amendment.** Issue #286 supersedes only the\r\n`REQ-CONN-POISON-ATTRIBUTION` leg-(d) requirement for unconditional\r\n*healthy start/close lines*. Across the broker process these become\r\n`CONN_LIFECYCLE_SUMMARY` totals, at most once per 60-second monotonic interval,\r\nflushed by the first subsequent lifecycle counter event. Starts count the\r\nfirst committed write attempt; closes count unpoisoned physical drops.\r\nThere is no timer thread and no shutdown flush, so a quiet tail remains\r\npending until another counter event (and can be lost on process exit).\r\nPoison, organic failure, poisoned close, and all role-transition records\r\nremain unconditional per connection. They retain conn id, role facts,\r\nwall/monotonic stamps **and the original first-write wall/monotonic time**;\r\na connection that never wrote says `first_write=none`.\r\n\r\nThe deterministic regression cells exercise real framed socket exchanges\r\nover both retained and fresh carriers with an isolated fixed log clock/sink,\r\nassert one interval summary for N healthy connections, preserve exceptional\r\nrecords through the same sink, and drive livehost census reuse plus recovery\r\nfrom a malformed reply.
