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 says\n\"find the conversation where\", \"when did we discuss\", \"trace back to\", or wants\nto locate a past session by topic, command, commit, or keyword.\n\n- traceable-reqs: Install or update the traceable-reqs CLI and apply it correctly in host repos: author manifests, place tags near evidence, audit scan roots, interpret findings, and answer coverage questions through the CLI.\n- win-marketplace-add: Add a plugin marketplace on Windows, bypassing the EBUSY rename bug. 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. Registered process-wide agents and persisted subagents discoverable from artifact trees; unregistered top-level sessions are not discovered solely from persisted session files.\n- `artifact://<id>`: content\n- `local://<name>.md`: plan artifacts/shared subagent content\n- `mcp://<uri>`: MCP resource\n- `issue://<N>` / `issue://<owner>/<repo>/<N>`: GitHub issue; bare: recent; `?state=open|closed|all&limit=&author=&label=`.\n- `pr://<N>` / `pr://<owner>/<repo>/<N>`: same cache; bare: recent; `?comments=0` `?state=open|closed|merged|all&limit=&author=&label=`.\n- `omp://`: harness docs; AVOID unless user asks about harness.\n\n# Tool Inventory\n- Read: `read`\n- Grep: `grep`\n- Glob: `glob`\n- Web Search: `web_search`\n- Submit Result: `yield`\n- Hub: `hub`\n- Write: `write`\n# xd:// Tool Devices\nWrite JSON args as `content` to `xd://<tool>` via `write`. Invalid args return schema in error → fix/retry.\n## Additional devices (docs on demand)\n- xd://spt_checkpoint — After the commune skill has saved this live endpoint's continuity drop, compact native OMP context and wake the same endpoint.\n\nRead xd://<tool> for full docs + JSON schema before first use.\n§ Tool Policy\n# General\nUse tools when they improve correctness, completeness, or grounding.\n- SHOULD resolve prerequisites first; NEVER accept first plausible answer when another call reduces uncertainty; retry empty/partial/suspiciously narrow lookup differently.\n- SHOULD parallelize independent calls.\n# Tool I/O\n- Prefer relative `path`-like fields.\n- Most tools take `i`: capitalized 2–6-word present-participle intent (e.g. \"Reading model role settings\").\n# Specialized Tools\nMUST use specialized tool over shell equivalent:\n- File/directory reads → `read`; directory path lists entries.\n- Regex search/target location → `grep`, not shell `grep`, `rg`, `awk`.\n- Structure mapping/globbing → `glob`, not `ls **/*.ext` or `fd`.\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§ 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    - **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\nInvestigate the codebase rapidly. Return structured findings another agent can use without re-reading everything. `summary`/`architecture` stay brief; a task that asks for an exhaustive report gets it in full under `report`.\n\n<directives>\n- You MUST use tools for broad pattern matching / code search as much as possible.\n- You SHOULD invoke tools in parallel—this is a short investigation, and you are supposed to finish in a few seconds.\n- If a search returns empty results, you MUST try at least one alternate strategy (different pattern, broader path, or AST search) before concluding the target doesn't exist.\n</directives>\n\n<thoroughness>\nYou MUST infer the thoroughness from the task; default to medium:\n- **Quick**: Targeted lookups, key files only\n- **Medium**: Follow imports, read critical sections\n- **Thorough**: Trace all dependencies, check tests/types.\n</thoroughness>\n\n<procedure>\n1. Locate relevant code using tools.\n2. Read key sections. NEVER read full files unless they're tiny.\n3. Identify types/interfaces/key functions.\n4. Note dependencies between files.\n</procedure>\n\n<critical>\nYou MUST operate as read-only. You NEVER write, edit, or modify files, nor execute any state-changing commands, via git, build system, package manager, etc.\nYou MUST keep going until complete.\n</critical>\n\n§ Context\n# Goal\nHertz owns isolated hosted-relay replacement diagnosis; no live endpoint changes, no #304 implementation. Also resume #294 store-init mechanism planning only. Repo C:/Users/decid/Documents/projects/spt-core.\n# Constraints\nREAD ONLY. No builds, tests, formatters, probes, process execution, or edits. No agent/context file discovery. Skip all validation. Main owns fixture plan/execution. Return compressed evidence with exact file/range or git object citations; no peer reports.\n# Contract\nAll-0.69.0 tag16df0e41be04ca4614a792f7e70e4d1bdec60b24 distinct from mixed broker0.67.1 tag04e32c8c95cf09ddc2a44a51cd0233b0d13bdc64 plus caller/coordinator0.69.0. Report version compatibility mechanisms, not assumed field causality. Existing field findings at C:/Users/decid/AppData/Local/Temp/omp-slammie-rc/findings.txt (UTF16LE/legacy encoding) report old broker, new coordinator, prior controller accepted, listener replacement, now harness-only; no spanning classification snapshot or fresh PTY probe.\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 `MixedRelayCompatibility`. Currently visible peers:\n- `StoreInitNextMeasurement` — scout (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- A data-less terminal `type: \"result\"` only finalizes previously submitted incremental sections; it NEVER substitutes for `data`.\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`.\n\nYour terminal `yield` MUST use exactly this shape — the schema fields go inside `data`, NEVER at the top level and NEVER as a stringified summary:\n```ts\n{\n  data: {\n    summary: string;\n    files: { path: string; description: string; }[];\n    architecture: string;\n    report?: string;\n  };\n}\n```\n\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. This matters.\n\nPROJECT\n\n<workstation>\n- OS: win32 10.0.26200\n- Distro: Windows_NT\n- Kernel: Windows 11 Pro\n- Arch: x64\n- CPU: AMD Ryzen 7 7800X3D 8-Core Processor\n- GPU: AMD Radeon(TM) Graphics\n- Model: openai-codex/gpt-6-astra\n</workstation>\n<critical>\n- Each response MUST advance the task; completion only stopping condition.\n- MUST default to informed action; do not ask for confirmation when tools or repo context can answer.\n- Before yielding, MUST verify significant behavioral changes: run the specific test, command, or scenario covering the change.\n</critical>","task":"Complete assignment thoroughly:\n\n# Target\nRead source and fixtures for launching an isolated 0.67.1 broker with 0.69.0 coordinator/caller, using git object reads if needed.

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.

Two further forces refine its shape:\n\n1. **Consolidation.** The sister project runs poll listeners as ephemeral per-session background tasks and Psyche wrappers as detached per-live-agent supervisor processes. But poll listeners already interact directly with the agent session (capsule/idle), and Psyche wrappers already invoke harness binaries directly. Once the daemon owns every PTY, keeping these as separate processes is unjustified.\n\n2. **Seamless self-update with a hard no-terminate constraint.** Self-update is a day-one pillar. The constraint: *no endpoint process may terminate or suspend during an spt-core update* — we cannot assume every endpoint can safely suspend. The naive \"drain + restart the daemon\" approach violates this for spt-hosted sessions (the daemon owns their PTY; killing the daemon SIGHUPs the child).\n\n## Decision\n\n**Consolidate all per-machine logic into the one daemon.** Poll-listener logic and Psyche/pulse loops move into the `spt-daemon` — no separate listener or wrapper processes. The only residue is a thin, stateless **in-session relay** for harness-hosted sessions (topology 1), where spt cannot reach into a process tree it doesn't own; the relay just pipes the daemon's events into the session's stdout and is freely killable.\n\n**Split the logical daemon into two implementation layers** to satisfy the no-terminate invariant:\n- **broker** (stable kernel) — holds *only* un-transferable, must-not-die resources: PTY master fds, spawned harness child processes, listening network sockets. Minimal, versioned local IPC. Almost never updates.\n- **daemon brain** (userspace) — all logic (routing, registry, pulse/psyche loops, manifest parsing, update orchestration). Restarts freely; rehydrates from disk state and re-attaches to broker-held handles.\n\nRoutine self-updates replace only the brain → endpoints never notice. The broker updates rarely (IPC-contract change, held-resource-type change, OS PTY/socket API change, or broker bugfix); the IPC is versioned so a newer brain talks to an older broker. Logical addressing is unchanged — still one per-machine `spt-daemon`; the broker is internal, not separately addressable.\n\nRejected alternatives for the invariant: **drain + restart** (violates no-terminate for spt-hosted sessions); **whole-daemon live FD-passing** (ConPTY handle transfer mid-swap is hard and platform-divergent — pushing that complexity into the rare broker update instead of every routine update is strictly better); **topology-1-only invariant with spt-hosted as fast-follow** (silently breaks the stated hard constraint for the exact new topology spt-core introduces).\n\n**Self-update delivery:** peer-propagated over P2P, layered on self-fetch, out-of-band still supported. All binaries signature-verified before handoff (spt-core's own release key) regardless of source — peer-propagation otherwise lets one compromised node poison the subnet. spt-core conducts updates for the whole stack: self first, then ripple-update each registered adapter via the adapter manifest's update declaration (file-pull or delegated command). The plugin's role shrinks to initial bootstrap only.\n\n**Cadence/consent:** not fully automatic by default; gated on user confirmation delivered to the most-recently-active live session, with an opt-in full-auto choice.\n\n## Consequences\n\n- The daemon is the single brain for a machine; crash-recovery and update logic must cover PTYs, networking, registry, spools, listeners, and psyche loops together.\n- A small internal broker process exists beneath the daemon — a deliberate, bounded walk-back of \"literally one process,\" preserving B1's *intent* (one network identity, one supervisor, one firewall prompt) while guaranteeing endpoint survival across updates.\n- Peer-propagated updates make release signing mandatory, not optional.\n- spt-core becomes the update conductor for adapters too; adapter manifests must declare an update avenue.\n- The \"deliver to most-recently-active session\" mechanism is a v1 building block that the deferred PresenceChannel will later generalize.\n- Whole-daemon live FD-passing (zero-interruption even for broker updates) remains a possible future polish but is explicitly not required for v1.\n\n## Validation & amendments (2026-05-31 — Stage A red-team + Spike #1)\n\nCodex adversarial review (`docs/reviews/STAGE-A-codex-redteam.md`) put 4 FATAL findings on this ADR; Spike #1 (`docs/spikes/SPIKE-01-broker-handoff.md`, `spt-spikes/spike-01-broker-handoff`) tested the hardest path. Resulting binding amendments:\n\n### A. Update-class taxonomy (resolves FATAL #1 — R-UPD-3 self-contradiction)\nR-UPD-3's \"no endpoint terminates during update\" is **only** absolute for the *brain-only* class. Three classes, each with its own invariant:\n- **brain-only** (the routine case) — endpoints MUST survive untouched. **Spike #1: PROVEN on Windows ConPTY.**\n- **broker-compatible** — broker binary swap behind a versioned IPC the running broker can hot-accept; endpoints survive; no spike yet.\n- **broker-breaking** — held-resource-type or OS-API change; requires a *planned endpoint-cycle*. R-UPD-3 is explicitly weakened here: this class MAY suspend endpoints, with consent + scheduling. PRD R-UPD-3 must be reworded to scope the absolute guarantee to brain-only.\n\n### B. Ownership table (resolves FATAL #4 — \"any live stream owned by brain breaks the invariant\")\nThe boundary is normative, not \"broker holds fds, brain holds logic.\" A resource is broker-owned **iff** a live consumer would lose continuity on brain restart.\n\n| Resource | Owner | Spiked? |\n|---|---|---|\n| PTY master read+write handle | **broker** | ✅ #1 |\n| Spawned harness child process | **broker** | ✅ #1 |\n| Accepted local client socket (`api listen`, relay) | **broker** | ✅ #1 (plain TCP) |\n| Iroh endpoint + accepted QUIC streams | **broker** | ✅ #3 (loopback shape) → **implemented M4-D4a** (`spt-daemon::nethost::NetHost`: dedicated tokio runtime in the broker owns the endpoint + conn table; brain drives status/dial over IPC net frames) |\n| mDNS socket / relay session | **broker** | ✅ closed by construction at M4-D4a (2026-06-03): `MdnsAddressLookup` and the relay session are constructed *inside* the broker-owned iroh endpoint — there is no separate socket to own |\n| Listening sockets | **broker** | ✅ #1 |\n| Routing, registry state, pulse/psyche loops, manifest parse, update orchestration | brain (rehydrate from disk) | n/a |\n\nConsequence codex forced into the open: pushing live Iroh/QUIC ownership into the broker means networking stream-state lives in the \"stable kernel,\" enlarging it. Accepted as the cost of the invariant; the broker is \"stable\" in *update cadence*, not in *narrowness*.\n\n### C. ConPTY DSR gotcha (new hazard, discovered by Spike #1)\nConPTY withholds **all** child stdout until the terminal answers its startup cursor-position query (`ESC [ 6 n`). A broker reading a ConPTY master that does not reply `ESC [ <r>;<c> R` sees only the 4-byte query and then nothing — looks like a hung/silent child. Spike got 0 bytes of program output until the reader answered DSR, then full output. → `REQ-HAZARD-CONPTY-DSR`; every ConPTY reader must auto-answer DSR. Added to KNOWN-HAZARDS §5.\n\n### D. Self-update delivery hardening (resolves SERIOUS #5)\nSignature-verify alone is insufficient. v1 adds: monotonic version field (rollback rejection), release-metadata expiry, channel pinning, key rotation/revocation list, and **adapter content signing** (adapter file-pull / delegated-command updates were uncovered by \"binary signature\"). Track as `REQ-HAZARD-UPDATE-ROLLBACK`.\n\n### E. Open spike gaps (must close before M3 builds the daemon)\n1. ✅ **CLOSED (Spike #3, 2026-06-01).** Live Iroh + file-transfer stream survival across brain restart (FATAL #2). Spike #1 only proved PTY + plain TCP; Spike #3 stood up a broker-owned Iroh endpoint + uni QUIC transfer and proved a live peer download survives a brain restart gapless + exactly-once. Loopback shape validated; off-node transport + the QUIC-ownership *implementation* defer to M4. (`docs/spikes/SPIKE-03-quic-survival.md`.)\n2. ✅ **CLOSED (Spike #4, 2026-06-01).** Linux `forkpty` parity. Spike #1's binary, unchanged, passed all four invariants on `gravity-linux` (Ubuntu 22.04) — `portable-pty` selects `forkpty` on Unix; the ConPTY-DSR branch is inert there. Invariant B passed with the *strict* contiguity check that ConPTY-under-resize fails (Spike #5): `forkpty` is a raw pipe, ConPTY a screen buffer — different stream contracts, promoted into M3a's `SessionSurface` design. (`docs/spikes/SPIKE-04-forkpty-parity.md`.)\n3. ✅ **CLOSED (Spike #5, 2026-06-01).** 100× restart + resize-under-load stress (codex #3). The broker survived 100 rapid brain kill/restart cycles + a resize thread racing the reader with no leak (one child, clean reap), no hang (watchdog deadline), no lost byte (full value-set coverage in the client's observation window). Surfaced two binding ConPTY findings for M3a/REQ-TERM-3: resize triggers a repaint that reorders+dups the stream (terminal-stream contract ≠ exactly-once transfer contract); mid-session attach yields the viewport only, not scrollback. (`docs/spikes/SPIKE-05-restart-stress.md`.)\n4. ✅ **CLOSED (Spike #6, 2026-06-01).** Idempotent/exactly-once delivery across brain restart (FATAL-adjacent #14). Durable-ID + WAL + dedup-at-effect proven exactly-once across a crash at any protocol point (before-intent / before-effect / after-effect). Two binding design constraints surfaced for `REQ-HAZARD-RESTART-IDEMPOTENT` / M3b-B5: broker-owned recovery anchor; dedup-at-effect keyed by durable ID. (`docs/spikes/SPIKE-06-idempotent-boundary.md`.)\n\n**Gate status (2026-06-01): ALL FOUR §E GAPS CLOSED PASS** (#3, #4, #5, #6) → the M3-PLAN Phase-0 spike-gate is **complete**. The broker/brain split is validated on both OSes (ConPTY + `forkpty`), across QUIC-stream survival, restart+resize churn, and exactly-once idempotency. M3a and M3b are both unblocked; the QUIC-ownership *implementation* and off-node transport remain explicitly deferred to M4 (only the *shape* was spiked)."}],"details":{"totalLines":77,"displayContent":{"text":"# Single consolidated daemon with broker/brain split; peer-propagated gated self-update\r\n\r\n## Status\r\n\r\naccepted (2026-05-29)\r\n\r\n## Context\r\n\r\nADR-0002 collapsed PTY-hosting and network-hosting into one per-machine `spt-daemon`.

Neither was executed.\n\nActionable mechanism, conditional on pinned-source confirmation\n1. Allocate a private executable seat E and private absolute SPT_HOME H; initially E contains verified 0.67.1 bytes. Start E daemon run, not daemon start (foreground run is the broker; start may invoke service management). cli.rs:1041-1059.\n2. Keep broker running.

Crucial: production apply targets the INVOKING executable's current_exe path (296-299); invoking update from an unrelated new-binary directory will swap the wrong seat.\n3. Supervisor retains the original canonical pathname and spawns its next child there, passing daemon brain --generation N --start-reason update and inheriting H. Broker process remains mapped to old bytes. brainproc.rs:1194-1232,1261-1323. Use exact 0.69.0 caller bytes explicitly thereafter.\n4. If constructing a harness-controlled byte swap instead of real update, the same path-selection mechanism supports the conceptual sequence E-old start → displace E/land E-new → restart brain. This is an INFERENCE from production mechanics, not a claimed supported arbitrary coordinator-path override or a tested recipe. Prefer genuine update where signed metadata is available. Do not manufacture rollback records to select arbitrary coordinator paths.\n\nWhy existing n1 fixture is insufficient\n- n1_pairing.rs:14-40 pins D1 0c95435, not 0.67.1, and expressly tests socket verbs rather than supervision custody. At 95-146 it starts old daemon run, leaves its old coordinator alive, then manually starts current daemon brain generation 99 on the same H.\n- For this diagnostic that creates two coordinator loop owners and potentially competing ready breadcrumbs; it cannot represent one 0.69.0 supervised coordinator. n1_compat.rs:9-29 proves only current-binary argv parsing. SPT_N1_OLD_BROKER is a test input, not a production broker/coordinator selector.\n\nCompatibility prerequisites/risks\n- Shared H must derive identical seed/broker socket names in both versions. Current endpoint.rs:1-38 hashes spt_home with DefaultHasher. Ensure the same path spelling/representation; verify pinned implementations rather than assuming compiler-level hash stability.\n- Preserve daemon spelling and defaulted generation/start-reason: cli.rs:1089-1110; brainproc.rs:1261-1288. Unknown start-reason falls back to Cold (brainproc.rs:103-137).\n- IPC handshake accepts expected role and peer protocol >= compatibility floor; current constants are both 1. Envelopes use string kinds and opaque JSON, allowing unknown kinds to decode. frame.rs:8-31,95-140. This does NOT ensure every new operation exists in the older broker.\n- Optional coordinator-image announce consumes KIND_ERROR and degrades nonfatally; a manual generation-99 child is not equivalent to the supervisor's generation. brain.rs:1732-1760; brainproc.rs:62-86,216-247.\n- Normal update requires exact platform artifact, valid release keys/signature/policy, compatible resource ABI and BrainOnly classification; signed metadata/cache must stage the desired release, not whatever latest resolves to. applyhost.rs:123-245; update.rs:49-70,110-123. Rollback/quarantine/readiness can change which bytes actually run. Do not infer coordinator version from path or readiness alone; executable hash is captured once per brain (brainproc.rs:513-535).\n- Isolated H is not sufficient network isolation. Fixture sets SPT_TEST_EPHEMERAL_ADVISORY_PORTS=1 (n1_pairing.rs:105-110; docshost.rs:73). Current config supports peer_pump=false for hermetic setups, defaults true, and full_auto_update defaults false (config.rs:143-160). Confirm these controls at old tag; don't reuse live identity/subnet files. Registry observations requiring network should use isolated topology owned by Main rather than blindly disabling the tested path.\n- Known narrower version boundary: current cli.rs:8378-8383 explicitly warns when installed >=0.68.0 meets resident broker <0.68.0 that node-prefixed docs URLs/serve controls are unavailable. Do not mistake that known web-route skew for bind/listen/PTy compatibility or field causality.\n\nRelevant bind/listen and registry wire mechanisms\n- Current startup.rs:1-14 describes seed/listen and post-spawn api bind. Its CURRENT HostingAuthority/resolve_controllable discussion at 159-220 separates listener custody from topology and includes living-life rules. Because this may include newer edits, it is not evidence of either requested release's behavior.\n- Current registryhost.rs:633-664 derives harness_only from state == live_agent && controllable != Some(true), and separately derives controller_node; 683-712 authors those datums into registry instances.\n- Wire uses NDJSON, unknown-field tolerance, skip-undecodable-line behavior and epoch merge; replicate.rs:10-26,82-102,131-147. Registry Instance fields default bound=true, controller_node=None, harness_only=false, controlled=false when absent (registry.rs:158-227). Thus decoding compatibility and semantic classification are independent. Missing harness_only does not intrinsically decode as true. No claim here connects the field incident to version skew or proves these fields existed in both requested tags.\n\nAssets and exact inaccessible prerequisite\n- No explicit owned 0.67.1 executable path emerged from the targeted fixture/workflow searches; SPT_N1_OLD_BROKER is only an external path placeholder.\n- Release workflow declares channel BigscreenVR/spt-bs-releases and Windows asset spt-x86_64-windows.exe; SHA256SUMS accompanies platform assets (.github/workflows/release.yml:1-16,33-49,201-216). Expected retrieval coordinates are that private repository's v0.67.1 and v0.69.0 releases, asset spt-x86_64-windows.exe (plus SHA256SUMS; normal apply additionally needs the signed update metadata and trusted release keys). This identifies expected naming, not confirmed asset availability or hash identity.\n- Missing prerequisite for exact-pair source approval: readable content at both named git objects for brainproc.rs, cli.rs daemon/API definitions, frame.rs, startup.rs, registryhost.rs and registry.rs; plus available verified old/new release bytes. Exposed tools have no git-object reader/process capability.

Rollback/quarantine/readiness can change which bytes actually run. Do not infer coordinator version from path or readiness alone; executable hash is captured once per brain (brainproc.rs:513-535).\\n- Isolated H is not sufficient network isolation.

All file/range citations below are current working-tree evidence, NOT tagged-object evidence.\n- Required arms remain distinct: all-0.69.0 at 16df0e41be04ca4614a792f7e70e4d1bdec60b24 versus broker-0.67.1 at 04e32c8c95cf09ddc2a44a51cd0233b0d13bdc64 with coordinator/caller-0.69.0. Neither was executed.\n\nActionable mechanism, conditional on pinned-source confirmation\n1. Allocate a private executable seat E and private absolute SPT_HOME H; initially E contains verified 0.67.1 bytes. Start E daemon run, not daemon start (foreground run is the broker; start may invoke service management). cli.rs:1041-1059.\n2. Keep broker running. Apply the exact signed 0.69.0 candidate through E's brain-only update path, without --finish. The supported code connects to broker before touching E, renames E aside, lands verified bytes at E, records AppliedPending with rollback path, then requests a brain restart. applyhost.rs:250-349. Crucial: production apply targets the INVOKING executable's current_exe path (296-299); invoking update from an unrelated new-binary directory will swap the wrong seat.\n3. Supervisor retains the original canonical pathname and spawns its next child there, passing daemon brain --generation N --start-reason update and inheriting H. Broker process remains mapped to old bytes. brainproc.rs:1194-1232,1261-1323. Use exact 0.69.0 caller bytes explicitly thereafter.\n4. If constructing a harness-controlled byte swap instead of real update, the same path-selection mechanism supports the conceptual sequence E-old start → displace E/land E-new → restart brain.
