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\nRead-only causal research for two Windows phase-B reds on 49a08a07 in spt-core; classify test/rig versus product without changing product. Main owns tests/runtime/proofs. Repo C:/Users/decid/Documents/projects/spt-core; successor tree .worktrees/asm-304-v3. User-reported failures are ground truth; do not reproduce or run tests.\n# Constraints\nSkip formatters, linters, builds and all validation/test commands. No edits, no lifecycle/host actions. Use available Rust LSP for code intelligence. Relevant core orientation was read by Main; read domain/ADR sections relevant to your seam. Do not investigate other agents' session files. Return evidence with exact symbols/locations, ranked causal predictions, not a speculative final classification.\n# Contract\nMain has read tests rc_attach_truth.rs:522-595 and restart_replay_lifetime.rs:363-611 plus actual failure transcript. Scout tasks own disjoint product-path research only. Delta 49a08a07 touches bootstrap_firewall modules and serveverb elevated-retry only, not these seams. Parent candidate b848244577d398600b59c7829fef9edbdb6315fa. No product fix authorized.\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 `ReplayStampSeam`. Currently visible peers:\n- `RegistrySeam` — scout (sub, running)\n- `Main` — main (main, running)\n10 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\nProduct control-stamp lifetime and ConnectionBound stream retirement/dispatcher replay paths corresponding to restart_replay_lifetime.rs.

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.

KNOWN-HAZARDS 7.44.\n\n## Context\n\nADR-0038 gave broker-held net streams truthful *dispatch* lifecycle: finished Attach rows\nretire, opener classification is restart-durable, claims retry bounded. Retirement was\ndefined as ELIGIBILITY-visibility only — the physical `StreamEntry` (send half, subscriber\nseats, writer threads) deliberately survives until the owning QUIC connection closes, so an\nin-flight reply always flushes.\n\nThe field (hertz, live v0.36 box) proved four compounding consequences on LONG-LIVED\nconnections, where the conn-close sweep never comes:\n\n1. **Sender history never retires.** The registry pump opens one fresh stream per feed\n   (~30s cadence) on the persistent pump conn and FINs it — but nothing retires the row:\n   the dispatcher is the sole `retire_stream` caller and it skips `initiated_locally` rows\n   by design. Sender rows accumulate unboundedly.\n2. **Enumeration is O(history) over IPC.** `stream_infos` filters `retired` only; every\n   dispatcher poll serializes the full historical row set to the brain merely for the\n   client to skip local rows.\n3. **Feed replay write-amplifies.** `serve_registry_feed` applies labels and instance flips\n   PER 64KiB transport chunk; both apply paths end in `write_snapshots` (full rewrite of\n   every subnet registry + heard.meta) — up to 2 full-state rewrites per chunk, synchronous\n   in the brain's event loop. While the brain does this it stops draining IPC; the broker's\n   seat writer blocks, hits the 15s SharedSend bound, poisons (12→15 observed\n   CONN_WRITE_POISONED, family=Registry), and the dispatcher re-replays from seq 0.\n4. **Completed seats retain OS threads — family-agnostically.** The broker conn loop\n   accretes `my_stream_subs` per subscribe and releases only at conn-loop exit; there is NO\n   net-stream unsubscribe verb. Every completed subscription on a long-lived carrier\n   (Registry, sync, update alike) keeps its parked SubscriberSeat writer thread: ~546 of\n   589 broker threads on the field box, unnamed.\n\nSeparately, the emphasys C2 report proved the inverse lifetime defect: an RC viewport whose\nopener Brain dies WITHOUT FIN leaves its attach stream alive-and-durable forever — the\ntarget never sees EOF, never detaches, and the controller slot + CONTROLLED stamps survive\neven a full broker restart. Durability, which is load-bearing for inter-brain streams\n(brain-swap), is wrong for connection-scoped viewers.\n\nBoth defect families are the same missing concept: **streams and seats have no declared\nlifetime class**, so everything defaults to maximally-durable, and the only reclamation\npoint is connection close.\n\n## Decision\n\n<!-- [doc->REQ-ONEWAY-STREAM-TERMINAL] -->\n1. **One-way (fire-and-forget) stream families are terminal at FIN, sender-side.** The\n   registry feed pump retires its own row after successful write+FIN via the existing\n   `net-stream-retire` verb (best-effort on N-1 brokers, per ADR-0038 A). A one-way\n   family's exchange is definitionally over at FIN; keeping the row eligible reproduces\n   the O(history) defect forever.\n2. **Eligibility filtering is server-side.** `stream_infos` excludes `initiated_locally`\n   rows (alongside `retired`) before serializing. Consumers keep their client-side guards\n   (double-filter harmless; N-1 compatible both directions).\n<!-- [doc->REQ-REGISTRY-APPLY-TRANSACTIONAL] -->\n3. **Feed application is transactional per feed.** Registry replay merges decoded records\n   in memory and writes snapshots ONCE at EOF (or one bounded batch commit for oversized\n   feeds). Snapshot writes scale O(feeds), never O(chunks × record-kinds). No synchronous\n   full-state rewrite inside a per-chunk event-loop iteration — this is the KH 7.12/7.43\n   discipline (no blocking work where it stalls a drain loop) applied to the brain side.\n4. **Poisoned one-way replays are bounded.** A deadline-poisoned Registry replay carries a\n   per-stream strike budget; at budget the row retires TERMINAL, loudly. Safe by family\n   semantics: a feed is an idempotent snapshot advertisement — the next pump round\n   re-advertises. (Request/reply families keep ADR-0038 Amendment circuit-breaker\n   semantics; terminal-at-budget applies to one-way families only.)\n<!-- [doc->REQ-SEAT-LIFETIME-BOUNDED] -->\n5. **Seats are released at serve completion — all families.** New broker verb\n   `KIND_NET_STREAM_UNSUBSCRIBE`: removes the SubscriberSeat, stops and joins its writer\n   thread, drops its cursor. Dispatch workers call it on serve completion (success or\n   failure); the retire sweep calls it for retired rows. Unknown-kind on an older broker is\n   the tolerated error path (best-effort caller). Physical resource lifetime on a\n   long-lived carrier becomes O(active serves), not O(carrier lifetime).\n<!-- [doc->REQ-STREAM-LEASE-CLASSES] -->\n6. **Streams declare a lifetime class at open.** Two classes:\n   - **ConnectionBound** — RC attach/view streams: opener connection EOF ⇒ the target sees\n     FIN, `serve_attach` runs `detach_session`, controller/viewer stamps clear. A dead\n     viewer can never pin a controller slot across its own connection's death.\n   - **Durable** — inter-brain streams (attach continuity across brain-swap, transfer):\n     unchanged ADR-0038 semantics. NEVER globally retire on Brain disconnect — brain-swap\n     correctness depends on it.\n   Late-close identity is validated (a stale opener A's close can't evict newer controller\n   B) — rides the ownership/generation tokens from ADR-0038 Amendment fix 6.\n7. **Spawned daemon threads are named** (SubscriberSeat writer `sub-writer-s<id>` minimum,\n   conn accept handlers next) — field thread censuses must attribute, not infer.\n\n## Consequences\n\n- Steady-state broker cost on long-lived conns: threads, rows, and IPC enumeration all\n  plateau at O(active). The field discriminators: hertz's preserved snapshot's poison count\n  freezes; brain CPU drops to noise (with the self-hash fix, REQ-BRAIN-HASH-ONCE); broker\n  thread census bounded and named.\n- New wire surface: `KIND_NET_STREAM_UNSUBSCRIBE` (additive, best-effort) + a lifetime\n  class on stream open (additive field; absent = Durable, so N-1 openers keep today's\n  semantics exactly).\n- The C2 endpoint-visible fix (controller slot freed on viewport death) lands in the\n  ENDPOINT-LIFECYCLE wave as `REQ-STREAM-LEASE-CLASSES`, built on decision 6 — one\n  mechanism, two waves, no double-build.\n- Registry feeds keep at-least-once semantics; the strike budget makes worst-case loss one\n  advertisement round (~30s), already the family's freshness unit.\n\n## Requirements\n\n`REQ-ONEWAY-STREAM-TERMINAL`, `REQ-STREAM-INFOS-SERVER-FILTER`,\n`REQ-REGISTRY-APPLY-TRANSACTIONAL`, `REQ-REGISTRY-REPLAY-BOUNDED`,\n`REQ-SEAT-LIFETIME-BOUNDED`, `REQ-HAZARD-REGISTRY-STALL` (KH 7.44),\n`REQ-STREAM-LEASE-CLASSES` (W2), with `REQ-BRAIN-HASH-ONCE` riding the same wave\n(independent defect, same field RCA).\n\n## Amendment 1 (2026-07-22, DAEMON-LIFECYCLE W2) — teardown authority is opener-declared class PLUS transport liveness, enforced at the three places decision 6 could not see\n\n<!-- [doc->REQ-STREAM-LIFETIME-CLASS] -->\n<!-- [doc->REQ-HAZARD-DRIVEN-BY-IDLE-REMOTE-EVICT] -->\n\nDecision 6 declared the two lifetime classes and shipped the CLEAN case: an\nopener conn that exits takes its `ConnectionBound` rows down with it, the target\nsees a FIN, `serve_attach` detaches, stamps clear. W2 asked the obvious next\nquestion — *which orderings can a class-bound seat outlive?* — and measured\nthree, RED-first where a fix might have been owed. **Two of the three were\nalready closed by composition, and the third heals on the transport's own\ntimer.** Nothing in this amendment adds a mechanism; it records what teardown\nauthority actually IS across all three, with the scope limits stated rather\nthan implied.\n\n**Teardown authority = the opener-declared CLASS + the TRANSPORT's liveness.**\nClass alone cannot decide: it only separates rows whose conn is *already known\ndead*. Liveness alone cannot decide: a `Durable` inter-brain row must survive\nits opener. The three enforcement points below are where the pair is read.\n\n### 1. Conn-exit sweep — shipped with decision 6, unchanged\n\nThe broker's conn-exit sweep FINs a `ConnectionBound` row and terminal-retires\nit; cross-node, `conn.closed()` retires the conn's rows (`nethost.rs`\n1000-1021). This is decision 6 as built.\n\n### 2. Restart replay — measured, NO filter owed (Leg A)\n\nADR-0038 decision 2 makes classification restart-durable, so a fresh dispatcher\ngeneration re-serves every retained opener Attach the broker still enumerates.\nA **`ConnectionBound` opener replaying is a class contradiction** — the conn\nthat declared the class cannot exist after the death that killed it — so this\nlooked like a leak needing a class filter at enumeration.\n\n**It is closed by composition, measured RED-first** (`restart_replay_lifetime.rs`,\nin-process duplex): sweep → FIN → `finished=true` →\n`finished_row_is_terminal(Attach, true)` → the row is retired UNSERVED by the\nnext generation. The seat does not re-establish. No filter, no wire field.\n\n**ADR-0038 decision 1 holds through its LIFECYCLE-STATE arm, NOT its\nenumeration arm — and this is a named reasoning hazard.** The dead opener's row\nis STILL enumerated as claimable after the sweep; it is merely `finished`. What\nstops the replay is retire-on-sight in the WORKER (`dispatch.rs`), DOWNSTREAM of\nthe claim. Two designers in one week reasoned from the arm that is not\nload-bearing — a broker-side filter \"at enumeration\" is the intuitive placement\nprecisely because decision 1 reads as if enumeration already excludes. It does\nnot. Any future filter on this seam belongs where the exclusion actually\nhappens, and its key is **\"is this row's transport conn alive\"**, not the class.\n\n**Scope limit, stated:** Leg A rode the IN-PROCESS DUPLEX (see the naming split\nbelow). The cross-node arm reaches the same outcome by a DIFFERENT mechanism\n(`conn.closed()` row retirement) and was not exercised there.\n\n### 3. Transport death without a FIN — measured, heals on the QUIC idle timeout (Leg B)\n\nThe half-open case decision 6 could not reach: the opener's conn is never\nclosed, because the peer's QUIC stack simply stops. Never measured on real QUIC\nbefore W2 — the standing \"clears on NEITHER platform at ANY window\"\ncharacterization was taken on the in-process duplex, where this shape is\n**unstageable by that code's own comment**.\n\n**Measured** (`transport_death_eof.rs`, real QUIC, two samples):\n\n| leg | seat released | row left the table |\n|---|---|---|\n| clean FIN (baseline + stop condition) | 120ms / 115ms | 120ms / 115ms |\n| torn, no FIN | 65057ms / 65047ms | 65027ms / 65021ms |\n\nThe already-serving `serve_attach` worker DOES receive the EOF: the read pump's\ntorn end (`Err(_) => finish()`) finishes the log exactly like a clean end, and\n`StreamLog::finish` pushes the EOF envelope to the seat installed on that same\n`Arc`'d log. Row removal cannot break an already-serving worker; it only breaks\nNEW lookups. The ~65s is `MESH_MAX_IDLE` (60s) plus quinn's PTO slack — a number\nmaterially UNDER 60s would have meant the staging leaked a signal, so the\nabove-60s landing is what makes the measurement trustworthy rather than merely\nfavourable.\n\n**Staging class — what the number is a number ABOUT.** The peer models a\n**QUIC-STACK-DEAD** host: its net runtime is frozen, so the endpoint is alive\nand its UDP port stays BOUND while nothing is ever sent or answered.

KNOWN-HAZARDS 7.44.\r\n\r\n## Context\r\n\r\nADR-0038 gave broker-held net streams truthful *dispatch* lifecycle: finished Attach rows\r\nretire, opener classification is restart-durable, claims retry bounded. Retirement was\r\ndefined as ELIGIBILITY-visibility only — the physical `StreamEntry` (send half, subscriber\r\nseats, writer threads) deliberately survives until the owning QUIC connection closes, so an\r\nin-flight reply always flushes.\r\n\r\nThe field (hertz, live v0.36 box) proved four compounding consequences on LONG-LIVED\r\nconnections, where the conn-close sweep never comes:\r\n\r\n1. **Sender history never retires.** The registry pump opens one fresh stream per feed\r\n   (~30s cadence) on the persistent pump conn and FINs it — but nothing retires the row:\r\n   the dispatcher is the sole `retire_stream` caller and it skips `initiated_locally` rows\r\n   by design. Sender rows accumulate unboundedly.\r\n2. **Enumeration is O(history) over IPC.** `stream_infos` filters `retired` only; every\r\n   dispatcher poll serializes the full historical row set to the brain merely for the\r\n   client to skip local rows.\r\n3. **Feed replay write-amplifies.** `serve_registry_feed` applies labels and instance flips\r\n   PER 64KiB transport chunk; both apply paths end in `write_snapshots` (full rewrite of\r\n   every subnet registry + heard.meta) — up to 2 full-state rewrites per chunk, synchronous\r\n   in the brain's event loop. While the brain does this it stops draining IPC; the broker's\r\n   seat writer blocks, hits the 15s SharedSend bound, poisons (12→15 observed\r\n   CONN_WRITE_POISONED, family=Registry), and the dispatcher re-replays from seq 0.\r\n4. **Completed seats retain OS threads — family-agnostically.** The broker conn loop\r\n   accretes `my_stream_subs` per subscribe and releases only at conn-loop exit; there is NO\r\n   net-stream unsubscribe verb. Every completed subscription on a long-lived carrier\r\n   (Registry, sync, update alike) keeps its parked SubscriberSeat writer thread: ~546 of\r\n   589 broker threads on the field box, unnamed.\r\n\r\nSeparately, the emphasys C2 report proved the inverse lifetime defect: an RC viewport whose\r\nopener Brain dies WITHOUT FIN leaves its attach stream alive-and-durable forever — the\r\ntarget never sees EOF, never detaches, and the controller slot + CONTROLLED stamps survive\r\neven a full broker restart. Durability, which is load-bearing for inter-brain streams\r\n(brain-swap), is wrong for connection-scoped viewers.\r\n\r\nBoth defect families are the same missing concept: **streams and seats have no declared\r\nlifetime class**, so everything defaults to maximally-durable, and the only reclamation\r\npoint is connection close.\r\n\r\n## Decision\r\n\r\n<!-- [doc->REQ-ONEWAY-STREAM-TERMINAL] -->\r\n1. **One-way (fire-and-forget) stream families are terminal at FIN, sender-side.** The\r\n   registry feed pump retires its own row after successful write+FIN via the existing\r\n   `net-stream-retire` verb (best-effort on N-1 brokers, per ADR-0038 A). A one-way\r\n   family's exchange is definitionally over at FIN; keeping the row eligible reproduces\r\n   the O(history) defect forever.\r\n2. **Eligibility filtering is server-side.** `stream_infos` excludes `initiated_locally`\r\n   rows (alongside `retired`) before serializing. Consumers keep their client-side guards\r\n   (double-filter harmless; N-1 compatible both directions).\r\n<!-- [doc->REQ-REGISTRY-APPLY-TRANSACTIONAL] -->\r\n3. **Feed application is transactional per feed.** Registry replay merges decoded records\r\n   in memory and writes snapshots ONCE at EOF (or one bounded batch commit for oversized\r\n   feeds). Snapshot writes scale O(feeds), never O(chunks × record-kinds). No synchronous\r\n   full-state rewrite inside a per-chunk event-loop iteration — this is the KH 7.12/7.43\r\n   discipline (no blocking work where it stalls a drain loop) applied to the brain side.\r\n4. **Poisoned one-way replays are bounded.** A deadline-poisoned Registry replay carries a\r\n   per-stream strike budget; at budget the row retires TERMINAL, loudly. Safe by family\r\n   semantics: a feed is an idempotent snapshot advertisement — the next pump round\r\n   re-advertises. (Request/reply families keep ADR-0038 Amendment circuit-breaker\r\n   semantics; terminal-at-budget applies to one-way families only.)\r\n<!-- [doc->REQ-SEAT-LIFETIME-BOUNDED] -->\r\n5. **Seats are released at serve completion — all families.** New broker verb\r\n   `KIND_NET_STREAM_UNSUBSCRIBE`: removes the SubscriberSeat, stops and joins its writer\r\n   thread, drops its cursor. Dispatch workers call it on serve completion (success or\r\n   failure); the retire sweep calls it for retired rows. Unknown-kind on an older broker is\r\n   the tolerated error path (best-effort caller). Physical resource lifetime on a\r\n   long-lived carrier becomes O(active serves), not O(carrier lifetime).\r\n<!-- [doc->REQ-STREAM-LEASE-CLASSES] -->\r\n6. **Streams declare a lifetime class at open.** Two classes:\r\n   - **ConnectionBound** — RC attach/view streams: opener connection EOF ⇒ the target sees\r\n     FIN, `serve_attach` runs `detach_session`, controller/viewer stamps clear. A dead\r\n     viewer can never pin a controller slot across its own connection's death.\r\n   - **Durable** — inter-brain streams (attach continuity across brain-swap, transfer):\r\n     unchanged ADR-0038 semantics. NEVER globally retire on Brain disconnect — brain-swap\r\n     correctness depends on it.\r\n   Late-close identity is validated (a stale opener A's close can't evict newer controller\r\n   B) — rides the ownership/generation tokens from ADR-0038 Amendment fix 6.\r\n7. **Spawned daemon threads are named** (SubscriberSeat writer `sub-writer-s<id>` minimum,\r\n   conn accept handlers next) — field thread censuses must attribute, not infer.\r\n\r\n## Consequences\r\n\r\n- Steady-state broker cost on long-lived conns: threads, rows, and IPC enumeration all\r\n  plateau at O(active). The field discriminators: hertz's preserved snapshot's poison count\r\n  freezes; brain CPU drops to noise (with the self-hash fix, REQ-BRAIN-HASH-ONCE); broker\r\n  thread census bounded and named.\r\n- New wire surface: `KIND_NET_STREAM_UNSUBSCRIBE` (additive, best-effort) + a lifetime\r\n  class on stream open (additive field; absent = Durable, so N-1 openers keep today's\r\n  semantics exactly).\r\n- The C2 endpoint-visible fix (controller slot freed on viewport death) lands in the\r\n  ENDPOINT-LIFECYCLE wave as `REQ-STREAM-LEASE-CLASSES`, built on decision 6 — one\r\n  mechanism, two waves, no double-build.\r\n- Registry feeds keep at-least-once semantics; the strike budget makes worst-case loss one\r\n  advertisement round (~30s), already the family's freshness unit.\r\n\r\n## Requirements\r\n\r\n`REQ-ONEWAY-STREAM-TERMINAL`, `REQ-STREAM-INFOS-SERVER-FILTER`,\r\n`REQ-REGISTRY-APPLY-TRANSACTIONAL`, `REQ-REGISTRY-REPLAY-BOUNDED`,\r\n`REQ-SEAT-LIFETIME-BOUNDED`, `REQ-HAZARD-REGISTRY-STALL` (KH 7.44),\r\n`REQ-STREAM-LEASE-CLASSES` (W2), with `REQ-BRAIN-HASH-ONCE` riding the same wave\r\n(independent defect, same field RCA).\r\n\r\n## Amendment 1 (2026-07-22, DAEMON-LIFECYCLE W2) — teardown authority is opener-declared class PLUS transport liveness, enforced at the three places decision 6 could not see\r\n\r\n<!-- [doc->REQ-STREAM-LIFETIME-CLASS] -->\r\n<!-- [doc->REQ-HAZARD-DRIVEN-BY-IDLE-REMOTE-EVICT] -->\r\n\r\nDecision 6 declared the two lifetime classes and shipped the CLEAN case: an\r\nopener conn that exits takes its `ConnectionBound` rows down with it, the target\r\nsees a FIN, `serve_attach` detaches, stamps clear. W2 asked the obvious next\r\nquestion — *which orderings can a class-bound seat outlive?* — and measured\r\nthree, RED-first where a fix might have been owed. **Two of the three were\r\nalready closed by composition, and the third heals on the transport's own\r\ntimer.** Nothing in this amendment adds a mechanism; it records what teardown\r\nauthority actually IS across all three, with the scope limits stated rather\r\nthan implied.\r\n\r\n**Teardown authority = the opener-declared CLASS + the TRANSPORT's liveness.**\r\nClass alone cannot decide: it only separates rows whose conn is *already known\r\ndead*. Liveness alone cannot decide: a `Durable` inter-brain row must survive\r\nits opener. The three enforcement points below are where the pair is read.\r\n\r\n### 1. Conn-exit sweep — shipped with decision 6, unchanged\r\n\r\nThe broker's conn-exit sweep FINs a `ConnectionBound` row and terminal-retires\r\nit; cross-node, `conn.closed()` retires the conn's rows (`nethost.rs`\r\n1000-1021). This is decision 6 as built.\r\n\r\n### 2. Restart replay — measured, NO filter owed (Leg A)\r\n\r\nADR-0038 decision 2 makes classification restart-durable, so a fresh dispatcher\r\ngeneration re-serves every retained opener Attach the broker still enumerates.\r\nA **`ConnectionBound` opener replaying is a class contradiction** — the conn\r\nthat declared the class cannot exist after the death that killed it — so this\r\nlooked like a leak needing a class filter at enumeration.\r\n\r\n**It is closed by composition, measured RED-first** (`restart_replay_lifetime.rs`,\r\nin-process duplex): sweep → FIN → `finished=true` →\r\n`finished_row_is_terminal(Attach, true)` → the row is retired UNSERVED by the\r\nnext generation. The seat does not re-establish. No filter, no wire field.\r\n\r\n**ADR-0038 decision 1 holds through its LIFECYCLE-STATE arm, NOT its\r\nenumeration arm — and this is a named reasoning hazard.** The dead opener's row\r\nis STILL enumerated as claimable after the sweep; it is merely `finished`. What\r\nstops the replay is retire-on-sight in the WORKER (`dispatch.rs`), DOWNSTREAM of\r\nthe claim. Two designers in one week reasoned from the arm that is not\r\nload-bearing — a broker-side filter \"at enumeration\" is the intuitive placement\r\nprecisely because decision 1 reads as if enumeration already excludes. It does\r\nnot. Any future filter on this seam belongs where the exclusion actually\r\nhappens, and its key is **\"is this row's transport conn alive\"**, not the class.\r\n\r\n**Scope limit, stated:** Leg A rode the IN-PROCESS DUPLEX (see the naming split\r\nbelow). The cross-node arm reaches the same outcome by a DIFFERENT mechanism\r\n(`conn.closed()` row retirement) and was not exercised there.\r\n\r\n### 3. Transport death without a FIN — measured, heals on the QUIC idle timeout (Leg B)\r\n\r\nThe half-open case decision 6 could not reach: the opener's conn is never\r\nclosed, because the peer's QUIC stack simply stops. Never measured on real QUIC\r\nbefore W2 — the standing \"clears on NEITHER platform at ANY window\"\r\ncharacterization was taken on the in-process duplex, where this shape is\r\n**unstageable by that code's own comment**.\r\n\r\n**Measured** (`transport_death_eof.rs`, real QUIC, two samples):\r\n\r\n| leg | seat released | row left the table |\r\n|---|---|---|\r\n| clean FIN (baseline + stop condition) | 120ms / 115ms | 120ms / 115ms |\r\n| torn, no FIN | 65057ms / 65047ms | 65027ms / 65021ms |\r\n\r\nThe already-serving `serve_attach` worker DOES receive the EOF: the read pump's\r\ntorn end (`Err(_) => finish()`) finishes the log exactly like a clean end, and\r\n`StreamLog::finish` pushes the EOF envelope to the seat installed on that same\r\n`Arc`'d log. Row removal cannot break an already-serving worker; it only breaks\r\nNEW lookups. The ~65s is `MESH_MAX_IDLE` (60s) plus quinn's PTO slack — a number\r\nmaterially UNDER 60s would have meant the staging leaked a signal, so the\r\nabove-60s landing is what makes the measurement trustworthy rather than merely\r\nfavourable.\r\n\r\n**Staging class — what the number is a number ABOUT.** The peer models a\r\n**QUIC-STACK-DEAD** host: its net runtime is frozen, so the endpoint is alive\r\nand its UDP port stays BOUND while nothing is ever sent or answered. That\r\ndistinction is load-bearing and asserted, not assumed: a bare host drop or a\r\nprocess kill CLOSES the socket, which answers keepalives with ICMP\r\nport-unreachable — a refusal, not silence, and a different (faster) shape than\r\nthe field's sleeping laptop. The rig asserts the port is still bound after the\r\nsever, and proves the freeze landed by watching the net runtime's reactor canary\r\ngo stale (0ms → 2006ms) after asserting it was fresh beforehand — a capability\r\nprobe on the instrument itself, in the RC-RENDER-TRUTH oracle discipline.\r\n\r\n**DECISION, taken ON the number: ACCEPT AS DOCUMENTED.** No presence-FIN\r\nsynthesis, no keepalive tune. Grounds:\r\n\r\n1. **The latch is not a lockout.** A different-conn attach during the window is\r\n   an ADR-0038 fix-6 successor and takes the seat immediately — the returning\r\n   operator, or a second one, is never blocked by the dead seat.\r\n2. **The residual harm is stale status truth** (CONTROLLED / `driven_by` /\r\n   viewer count) for ~65s after an abrupt transport death — a rare event that\r\n   self-heals on a bound.\r\n3. **Synthesis would add a SECOND teardown mechanism** to shave ~60s off a case\r\n   that already converges, and every second mechanism on this seam is\r\n   historically where the bugs lived.\r\n4. **A keepalive tune is a GLOBAL QUIC tradeoff** (chatter, battery, mobile\r\n   paths) and is not spent on a cosmetic minute.\r\n\r\nThe revisit lever is NAMED, not built: if the window ever reads as bad product\r\nfeel, the tune is the keepalive interval, and it is a product-feel call with a\r\nfalse-evict bound to design — not a bug fix.\r\n\r\n`REQ-HAZARD-DRIVEN-BY-IDLE-REMOTE-EVICT` therefore stays `int`-only: the\r\nmeasurement is the deliverable, and impl/unit are NOT owed on this evidence.\r\n\r\n**Boundary, stated not implied (KH 7.15 / 7.29 carry it too):** this closes the\r\nDEAD-transport-no-FIN half only. The **ALIVE-but-WEDGED** controller (KH 7.15\r\nA2 — the QUIC stack keeps answering keepalives while only the app writer is\r\nparked) never fires an idle timeout at all, so nothing in the transport-death\r\nclass reaches it. That leg stays deferred, and a green transport-death rig must\r\nnever be read as covering it.\r\n\r\n**Confirmation outstanding:** both legs above were measured on local real QUIC\r\n(two brokers, one box). LAN confirmation over a real two-host path is insurance\r\non a decision that builds nothing, and rides the next box-occupancy window with\r\nthe gate battery.\r\n\r\n### Rejected alternative: a lifetime field on the opener reply\r\n\r\nProposed (todlando) and rejected on a REACH FACT that was not checked before\r\nproposing it: **the row a dispatcher re-serves is not the classed row.** The\r\nserved row is the ACCEPTED row (cross-node) or the loopback PEER row, and both\r\nregister `Durable` — class-blind BY DESIGN, because the lifetime class is\r\nOPENER-side (decision 6): a target experiences a `ConnectionBound` teardown as\r\nan ordinary FIN, never as a class of its own row (`nethost.rs` 1028-1041,\r\n1763-1771).\r\n\r\nA lifetime field on the opener reply would therefore report `Durable` for\r\n**exactly the population such a filter exists to catch** — undercounting the\r\nleaked rows to zero while spending wire surface on the wrong rows.

No tests, builds, commands changing state, lifecycle actions, or edits were performed. User-reported runtime observations were accepted, not reproduced. Test source inspection remained Main’s responsibility. Tool discovery (`read xd://`) exposed only spt_checkpoint, and no Rust LSP tool is available in this agent’s tool inventory; symbol/range searches were used instead.\n\n## Precise control lifetime and ordering\n\n### 1. Establishment\n`OutputLog::become_controller` (broker.rs:2592–2694) takes the previous sink, advances controller_epoch, constructs and installs the new ControllerSink, then calls `stamp_driven_by`, then `on_control_edge`. Thus live controller truth precedes its persisted representation.\n\n`stamp_driven_by` (broker.rs:3608–3627) requests an attachment observation, writes `set_driven_by(controller_by())`, then writes `set_controlled(controller.is_some())`. Errors are best-effort/discarded. `controller_by` and `has_controller` are separate facts (broker.rs:1603–1611). In particular, a local controller can truthfully be controlled=true with driven_by=None; the latter is not a standalone empty-slot predicate (info.rs:707–715).\n\n### 2. Serving-generation death\n`handle_conn` breaks on any `read_frame` error (broker.rs:6085–6090). After leaving the read loop it aborts ceremonies, clones only that connection’s subscribed session logs out of the shared table, and calls `detach_if(&send)` on them (broker.rs:6424–6448). Sessions/PTYS remain alive.\n\n`detach_if` checks current controller connection identity using Arc::ptr_eq (broker.rs:3562–3570). If this connection still owns the slot, `clear_controller` takes the sink and calls the same stamper (broker.rs:2752–2777), so the ordered publications are:\n\n1. in-memory controller=None;\n2. optional diagnostic `CONTROLLER_SLOT_CLOSED` (before persistence finishes);\n3. info.json driven_by=None;\n4. info.json controlled=false;\n5. control-edge work;\n6. `session-detach` lifecycle record (broker.rs:3576–3584).\n\nA newer controller on another connection is not cleared by old connection cleanup. The death of gen1’s process is not itself a barrier proving every old handler has reached step 4.\n\n### 3. Explicit controller detach after opener FIN\n`serve_attach` uses a receiving/controlling Brain connection and a separate wire-forwarding connection (attach.rs:483–503). On its stream EOF it first FINs the reply through `wire`, then feeds the resting Detach edge for a controller, then best-effort calls `brain.detach_session_gen(sid, Some(serve_gen))`, then returns Detached (attach.rs:872–888).\n\n`dispatch_unsubscribe` forwards to `detach_if_gen` (broker.rs:8815–8829). A mismatched request/serve generation leaves the newer controller intact, while viewer cleanup remains connection-identity based; a matching generation still passes through the connection identity check (broker.rs:3547–3570). `serve_gen` is copied from the attach request’s req_gen (attach.rs:417–434), NOT the daemon’s generation number.\n\nIf gen1’s serve worker is already dead, no surviving worker must execute this EOF branch. Old server-side connection cleanup is the independent route that releases its controller.\n\n### 4. ConnectionBound opener cleanup\nOn any opener IPC handler exit, broker.rs:6450–6474 first detaches net subscription seats, then for each tracked ConnectionBound stream executes `host.send_stream(id, [], true)`, `host.retire_stream_terminal(id)`, and emits `STREAM_CONNBOUND_RETIRE:<id>`. Both calls are best-effort. Durable opens do not enter this list.\n\nThe target read pump independently translates EOF/error into `StreamLog::finish` (nethost.rs:1144–1157); finish sets finished=true before enqueueing an EOF notification (nethost.rs:519–528). Therefore observing old opener row2 absent and target row1 finished proves transport/lifecycle progress, not completion of the old target controller’s file writes. Opener and old serving worker use different IPC handlers; their cleanup has no global join.\n\n### 5. Poison and delayed cleanup\nPoison does not clear stamps directly. On Windows `poison_and_cancel` latches poison and calls CancelIoEx; `sever` subsequently calls DisconnectNamedPipe plus another CancelIoEx, after canceled I/O completion, so reads fail and handle_conn can reach its exit cleanup (conn.rs:379–435). Writer failure/reaping provides another path: `reap_dead_controller` removes an exited writer in memory, or deferred-stall-evicts a blocked one, then KIND_SESSIONS convergence writes outside the log lock (broker.rs:2779–2821, 6314–6353).\n\nA genuinely idle writer awaiting its channel, whose IPC EOF has not been processed, is not inferred dead by writer-exit polling (broker.rs:2795–2800). Do not transplant ADR-0040’s approximately 65-second real-QUIC silence bound to this in-process duplex case; Amendment 1 explicitly distinguishes these transports.\n\n## Why the exact observed pair is significant\n\n`set_driven_by` and `set_controlled` each call `mutate_info` independently (info.rs:703–715). Each invocation acquires the per-perch sentinel, reads, modifies one field, and writes the full record (info.rs:500–509). Readers remain lock-free (info.rs:485–487). Per-write atomicity prevents torn JSON, but does not make the two-field transition atomic.\n\nThus a normal clear from {controlled:true, driven_by:Some(old)} publishes {controlled:true, driven_by:None} between the two setter calls. File locking, scheduling, and actual writes can expose that intermediate state to a watcher. It can also be a pre-existing local-controller state. Neither interpretation requires gen2 to execute any attach code.\n\n[INFERENCE] Given the supplied 0.29-second body and immediate true/None sample, the highest-value prediction is that the watcher starts without first establishing a post-gen1 cleared baseline and accepts an existing true level as a resurrection. The observed pair specifically fits the middle of the clear path. Source cannot prove that this particular sample was between the setters; it establishes a concrete sufficient mechanism.\n\n## Can the old finished row replay?\n\nThe row types in T2 are expected: class is opener-side. The accepted/duplex peer stays Durable; ADR-0040 Amendment 1 explicitly rejects filtering the served row by class (ADR:240–245). A claimable finished row is NOT already a retired row.\n\nThe dispatch loop captures `s.finished` when enumerating and passes it into worker (dispatch.rs:729–767). Worker first classifies the pinned opener, then calls `finished_row_is_terminal`; finished && Attach returns Served(\"finished attach: terminal, retired unserved\") BEFORE creating the serving Brain or invoking serve_attach (dispatch.rs:1033–1107; discriminator at 573–574). Completion then invokes net_stream_retire (dispatch.rs:778–785).\n\nEligibility retirement hides a row from stream enumeration and opener queries (nethost.rs:1956–1962, 2005–2038, 2079–2085); terminal retirement physically removes it (2053–2071). A physically retained but eligibility-retired row is not replay-eligible. A finished but not yet retired target Attach may still be claimed, but it is retired unserved. This is precisely ADR-0040 Amendment 1:149–160, which warns that the lifecycle-state worker gate, not an enumeration-time finished filter, is the load-bearing exclusion.\n\n[INFERENCE] Because the supplied T2 says row1 was already finished before gen2, the stale-enumeration variant (worker captured unfinished before FIN) is lower-ranked for this observation. It would require a different ordering than the supplied setup. Do not infer actual execution from row1 being claimable or from it remaining Durable.\n\n## Ranked causal predictions and discriminators\n\n1. **Oracle mistakes old/intermediate level for a gen2 edge — strongest.** Prediction: a raw info.json baseline taken after old controller release has completed and before gen2 starts will be false/None; gen2 will not subsequently establish control from row1. A watcher armed while true/None still exists can immediately declare resurrection without any gen2 attach execution. This directly fits the supplied old-row replay=false observation, subject to what that observation measures.\n2. **Real transient or persistent stale-stamp problem, separate from replay.** Prediction: the old slot is gone, no gen2 attach reaches establishment, but disk still reports control. A short true/None interval is permitted by the two-write implementation. Persistence after completed cleanup and a current authoritative sessions/convergence pass would instead support a stamp-write/convergence issue; that would not establish stream replay.\n3. **Actual old-row replay/steal — lower on supplied evidence.** Prediction: gen2 executes the old request’s attach path, producing an establishment event attributable to the old request/session/connection, or demonstrably changes live controller ownership before any fresh sibling exists. That is incompatible with normal execution of worker’s finished=true gate and would demand evidence about captured finished state, classification, or an alternate attach path.\n\nClean observational sequence for Main’s rig work: keep gen2 stopped; observe old serving controller closure and complete false/None baseline separately from opener row retirement; then start gen2 and watch for a NEW attributable control establishment, retaining the whole pre-sibling interval. Diagnose any failure to reach the baseline as stale cleanup rather than labeling it resurrection. Do not let the fresh sibling overwrite the evidence: T3 after rows3/4 succeed legitimately contains sibling-driven state and cannot retrospectively identify row1 as its cause.\n\nExisting event options:\n- `CONTROLLER_SLOT_CLOSED` (diag-gated, broker.rs:2759–2770) proves a real in-memory close, but precedes stamp completion.\n- `CONN_LIFECYCLE event=session-detach` with was_controller=true is emitted after clear_controller returns (broker.rs:3576–3584); pair it with an actual disk read because setters discard errors.\n- `CONN_LIFECYCLE event=controller-attach` is emitted in become_controller (broker.rs:2604–2614); use conn/session attribution and the before-sibling window. It is not itself proof both disk writes completed.\n- `ATTACH_INTENT_CHOSEN: site=serve_dispatch ... gen=<request-gen>` (attach.rs:407–434) proves the establishment path was reached; it occurs before attach_as_coded, so pair it with broker acceptance/actual slot establishment. Request generation is not gen2’s process generation.\n- `STREAM_CONNBOUND_RETIRE` proves the opener sweep ran, not target stamp convergence.\n- `DISPATCH:<id>` is emitted only for non-Served outcomes (dispatch.rs:797–806). Its absence does NOT prove no replay or successful retirement; ADR-0040:269–272 explicitly prohibits that success oracle. The generic Served counter also counts finished-Attach retire-unserved (dispatch.rs:771–785), so it cannot distinguish establishment from exclusion by itself.\n\nAn authoritative sessions query is not a passive disk probe: KIND_SESSIONS reaps and converges stamps (broker.rs:6314–6353). If used to establish baseline, record that it drives cleanup. The serialized SessionInfo reply exposes controller_by but not has_controller (broker.rs:6355–6365); None alone cannot distinguish empty from a local controller.\n\n## Product invariant boundary\n\nADR-0040 decision 6 (81–86) forbids a dead ConnectionBound viewport from indefinitely pinning the controller; Amendment 1 requires no re-establishment from the finished old Attach. The supplied T2 transport facts and replay=false are consistent with, not contradictory to, that composition.\n\nADR-0041 decision 4 (62–65) requires validated control-stamp convergence, and broker.rs:1174–1251 implements divergence-gated repair with a per-endpoint generation guard against session reap. Lasting controlled=true while the authoritative slot is absent would violate control-status convergence, even if stream replay is perfectly excluded. An instantaneous true/None sample does not demonstrate that lasting violation; the code explicitly publishes that intermediate pair, and true/None can also be a valid local controller.\n\nA separate source-level race worth keeping distinct, not a finding for this red: session snapshots are taken under the log lock and converged later off-lock; the stamp generation described at broker.rs:1144–1153 advances for definitive session reap, not ordinary controller detach. A pre-detach snapshot can therefore be stale relative to a controller edge while its session generation still matches. The next census is intended to converge it. No supplied evidence identifies that interleaving here, and no product change is justified from it alone.\n\nNo final test-versus-product classification is made from source alone. The causal prediction favors a resurrection-oracle precondition defect; an independently measured failure of stamp convergence would remain a real product issue rather than being excused by the replay gate."},"error":null}}],"api":"openai-codex-responses","provider":"openai-codex","model":"gpt-6-astra","usage":{"input":2598,"output":3491,"cacheRead":68096,"cacheWrite":0,"totalTokens":74185,"reasoningTokens":25,"cost":{"input":0.025980000000000003,"output":0.17455,"cacheRead":0.068096,"cacheWrite":0,"total":0.26862600000000003}},"stopReason":"toolUse","timestamp":1789376827098,"responseId":"resp_00b7f99998116c1e016aa7b93b546c87d1a767926c451c026d","providerPayload":{"type":"openaiResponsesHistory","provider":"openai-codex","dt":true,"items":[{"id":"rs_00b7f99998116c1e016aa7b93c77b887d18e93fde91c4b94bc","type":"reasoning","content":[],"encrypted_content":"gAAAAABqp7k_6_YWmLVfS_vl57RKTDT7XE1UQsTWQ6YXEiJnSDUZ9JRrYfM1CsP02Mo3ZxdawnBsbQVL0uioczl0rB5NJysftssSQSecBO5aMavI6KPsqmG58a4oQzODovnyNRGkreYBNzHSCgx6nB2g-lrM1e9zEOdY6gmXyi6iT4jyfH31atP_Uc4zacRbT8w4V8SuArDIkZz_E0YGyW8NJrExcNJ3t2Y8Z-sEDXKd7xUATNKI97qKlzi26ZOg1ltXSIIA6Yy19vbCMfGapL9uCLcDBPmD0c2mtSu4fmi12vLGAcjDxtkmryKbKhiGYJarpvUKSBRv-NQvKNVHiYgr538vcKQ_3ZI4o5QeBdJCiBhjqs36s59_CN0XRJQTsC9EFcXM7FszJaI9JZ_nD1fbg4axZwg66Cig4KQZ497HnepxBdruJAAujugnyu-ZIYRPEi9G8pmT4YW59pdnpyJvpIvkaUqjQF0-JNBpqd47B5a0zxTaP67dgAykyGpn1n5evA7KkAvtgsD3kzzu_HCX5QRKhjHZ3G_vQHuM8D43PKaqxB3oEZhLWpCwmmbhXWNCwdltus1SZQiRElYdMEp-qcRLt4I53Aohz5Wz6u8pPLxYGSS9CaWVwbm-UNfcSTBaQxozjZTsKHVt_e4GnpeKC7A1rUBIz0tAr0_sTI5e-WinB4H--n-hW7oaFLtaTiJ8-KoS86MSA68nUhjGS6U9AWqO4dibOuh6XnmDGp_2RnDX5ApOhdARmaxUhI_866Y8utBX8_xUNy5IF_zvelRPeBtPHf0SDr72a_ocuOJghCjCs0ku_CkFo0GFG3sPfAtfxU7VdehKQDnTdd2PTslZIJSCt1jYqUq3TWY8c_DwrIm9DmbCbBI7onLl-4PuqIvX8_7Tc-JGA6m3wYnPc-8-IjJb9aOhg1VVU_Aqlq-8R3H2y9CaagwLYbl1gJcEbveAXKc3C-_IMNbEId4c5tsuP8mtXmzlHZ8JE13Sz7h4jpmkRf0WgJBBoM-jc1RgElo4CMVAbMKw5G1NPe5b4ARemmkpzdjpQ8q3WD54cfxv3N_ydHoq4ORd0NioHXB-CX6ITXmhx-3ieO15Xxy7e4CK6gZPiwBk3bR728zmukcnsXQIcPGK7n8U_gBiOs44hD92tAARlx1t-hsdLm1BK_ZR_iacehhwpjVfcojSl4c1wcp6Y6E6A15hr262d6o7sThykHD0YxH53xX5i1eFWKWWMEkn1g6LHfX58ylNAPGkpI16E3RfWQWQeIIVy_r_Ai9tCUx4NYaXKfl0bG9ubhhK3_ZgnRlvrP-fEsvM-FMuHI0u6L_JYxjmMjURFr-FDintW8beajqwRNAsGEMlHotKXwzYgpwUlpM44d6K6r-4BSvntjZqCQoF8V9qiJBRQlUGf3jQFL6ymp5K80NZk26JzOZvlrMLxxy_27Es6zG4SRDAt0_Mbj8=","internal_chat_message_metadata_passthrough":{"turn_id":"b6e714ed-f525-4a2d-8cc2-ff30f258ea5d"},"summary":[],"metadata":{"turn_id":"b6e714ed-f525-4a2d-8cc2-ff30f258ea5d"}},{"id":"fc_00b7f99998116c1e016aa7b93f915487d1bf0d2fe7436b1735","type":"function_call","status":"completed","arguments":"{\"type\":null,\"data\":{\"summary\":\"Strongest prediction: the immediate controlled=true/driven_by=None observation is a pre-existing or partially cleared control level, not evidence of gen2 replay.

A physically retained but eligibility-retired row is not replay-eligible. A finished but not yet retired target Attach may still be claimed, but it is retired unserved. This is precisely ADR-0040 Amendment 1:149–160, which warns that the lifecycle-state worker gate, not an enumeration-time finished filter, is the load-bearing exclusion.\\n\\n[INFERENCE] Because the supplied T2 says row1 was already finished before gen2, the stale-enumeration variant (worker captured unfinished before FIN) is lower-ranked for this observation. It would require a different ordering than the supplied setup. Do not infer actual execution from row1 being claimable or from it remaining Durable.\\n\\n## Ranked causal predictions and discriminators\\n\\n1. **Oracle mistakes old/intermediate level for a gen2 edge — strongest.** Prediction: a raw info.json baseline taken after old controller release has completed and before gen2 starts will be false/None; gen2 will not subsequently establish control from row1. A watcher armed while true/None still exists can immediately declare resurrection without any gen2 attach execution. This directly fits the supplied old-row replay=false observation, subject to what that observation measures.\\n2. **Real transient or persistent stale-stamp problem, separate from replay.** Prediction: the old slot is gone, no gen2 attach reaches establishment, but disk still reports control. A short true/None interval is permitted by the two-write implementation. Persistence after completed cleanup and a current authoritative sessions/convergence pass would instead support a stamp-write/convergence issue; that would not establish stream replay.\\n3. **Actual old-row replay/steal — lower on supplied evidence.** Prediction: gen2 executes the old request’s attach path, producing an establishment event attributable to the old request/session/connection, or demonstrably changes live controller ownership before any fresh sibling exists. That is incompatible with normal execution of worker’s finished=true gate and would demand evidence about captured finished state, classification, or an alternate attach path.\\n\\nClean observational sequence for Main’s rig work: keep gen2 stopped; observe old serving controller closure and complete false/None baseline separately from opener row retirement; then start gen2 and watch for a NEW attributable control establishment, retaining the whole pre-sibling interval. Diagnose any failure to reach the baseline as stale cleanup rather than labeling it resurrection. Do not let the fresh sibling overwrite the evidence: T3 after rows3/4 succeed legitimately contains sibling-driven state and cannot retrospectively identify row1 as its cause.\\n\\nExisting event options:\\n- `CONTROLLER_SLOT_CLOSED` (diag-gated, broker.rs:2759–2770) proves a real in-memory close, but precedes stamp completion.\\n- `CONN_LIFECYCLE event=session-detach` with was_controller=true is emitted after clear_controller returns (broker.rs:3576–3584); pair it with an actual disk read because setters discard errors.\\n- `CONN_LIFECYCLE event=controller-attach` is emitted in become_controller (broker.rs:2604–2614); use conn/session attribution and the before-sibling window. It is not itself proof both disk writes completed.\\n- `ATTACH_INTENT_CHOSEN: site=serve_dispatch ... gen=<request-gen>` (attach.rs:407–434) proves the establishment path was reached; it occurs before attach_as_coded, so pair it with broker acceptance/actual slot establishment. Request generation is not gen2’s process generation.\\n- `STREAM_CONNBOUND_RETIRE` proves the opener sweep ran, not target stamp convergence.\\n- `DISPATCH:<id>` is emitted only for non-Served outcomes (dispatch.rs:797–806). Its absence does NOT prove no replay or successful retirement; ADR-0040:269–272 explicitly prohibits that success oracle. The generic Served counter also counts finished-Attach retire-unserved (dispatch.rs:771–785), so it cannot distinguish establishment from exclusion by itself.\\n\\nAn authoritative sessions query is not a passive disk probe: KIND_SESSIONS reaps and converges stamps (broker.rs:6314–6353). If used to establish baseline, record that it drives cleanup. The serialized SessionInfo reply exposes controller_by but not has_controller (broker.rs:6355–6365); None alone cannot distinguish empty from a local controller.\\n\\n## Product invariant boundary\\n\\nADR-0040 decision 6 (81–86) forbids a dead ConnectionBound viewport from indefinitely pinning the controller; Amendment 1 requires no re-establishment from the finished old Attach. The supplied T2 transport facts and replay=false are consistent with, not contradictory to, that composition.\\n\\nADR-0041 decision 4 (62–65) requires validated control-stamp convergence, and broker.rs:1174–1251 implements divergence-gated repair with a per-endpoint generation guard against session reap. Lasting controlled=true while the authoritative slot is absent would violate control-status convergence, even if stream replay is perfectly excluded. An instantaneous true/None sample does not demonstrate that lasting violation; the code explicitly publishes that intermediate pair, and true/None can also be a valid local controller.\\n\\nA separate source-level race worth keeping distinct, not a finding for this red: session snapshots are taken under the log lock and converged later off-lock; the stamp generation described at broker.rs:1144–1153 advances for definitive session reap, not ordinary controller detach. A pre-detach snapshot can therefore be stale relative to a controller edge while its session generation still matches. The next census is intended to converge it. No supplied evidence identifies that interleaving here, and no product change is justified from it alone.\\n\\nNo final test-versus-product classification is made from source alone. The causal prediction favors a resurrection-oracle precondition defect; an independently measured failure of stamp convergence would remain a real product issue rather than being excused by the replay gate.\"},\"error\":null}","call_id":"call_GaVudN5Eie90Q2kysRePqWj4","internal_chat_message_metadata_passthrough":{"create_time":1789376827.54609,"turn_id":"b6e714ed-f525-4a2d-8cc2-ff30f258ea5d"},"name":"yield","metadata":{"turn_id":"b6e714ed-f525-4a2d-8cc2-ff30f258ea5d"}}]},"duration":106081.42650000751,"ttft":1393.5400000065565,"completedAt":1789376933182,"contextSnapshot":{"promptTokens":70694,"nonMessageTokens":10348,"compactionEpoch":0}}}

No tests, builds, commands changing state, lifecycle actions, or edits were performed. User-reported runtime observations were accepted, not reproduced. Test source inspection remained Main’s responsibility. Tool discovery (`read xd://`) exposed only spt_checkpoint, and no Rust LSP tool is available in this agent’s tool inventory; symbol/range searches were used instead.\n\n## Precise control lifetime and ordering\n\n### 1. Establishment\n`OutputLog::become_controller` (broker.rs:2592–2694) takes the previous sink, advances controller_epoch, constructs and installs the new ControllerSink, then calls `stamp_driven_by`, then `on_control_edge`. Thus live controller truth precedes its persisted representation.\n\n`stamp_driven_by` (broker.rs:3608–3627) requests an attachment observation, writes `set_driven_by(controller_by())`, then writes `set_controlled(controller.is_some())`. Errors are best-effort/discarded. `controller_by` and `has_controller` are separate facts (broker.rs:1603–1611). In particular, a local controller can truthfully be controlled=true with driven_by=None; the latter is not a standalone empty-slot predicate (info.rs:707–715).\n\n### 2. Serving-generation death\n`handle_conn` breaks on any `read_frame` error (broker.rs:6085–6090). After leaving the read loop it aborts ceremonies, clones only that connection’s subscribed session logs out of the shared table, and calls `detach_if(&send)` on them (broker.rs:6424–6448). Sessions/PTYS remain alive.\n\n`detach_if` checks current controller connection identity using Arc::ptr_eq (broker.rs:3562–3570). If this connection still owns the slot, `clear_controller` takes the sink and calls the same stamper (broker.rs:2752–2777), so the ordered publications are:\n\n1. in-memory controller=None;\n2. optional diagnostic `CONTROLLER_SLOT_CLOSED` (before persistence finishes);\n3. info.json driven_by=None;\n4. info.json controlled=false;\n5. control-edge work;\n6. `session-detach` lifecycle record (broker.rs:3576–3584).\n\nA newer controller on another connection is not cleared by old connection cleanup. The death of gen1’s process is not itself a barrier proving every old handler has reached step 4.\n\n### 3. Explicit controller detach after opener FIN\n`serve_attach` uses a receiving/controlling Brain connection and a separate wire-forwarding connection (attach.rs:483–503). On its stream EOF it first FINs the reply through `wire`, then feeds the resting Detach edge for a controller, then best-effort calls `brain.detach_session_gen(sid, Some(serve_gen))`, then returns Detached (attach.rs:872–888).\n\n`dispatch_unsubscribe` forwards to `detach_if_gen` (broker.rs:8815–8829). A mismatched request/serve generation leaves the newer controller intact, while viewer cleanup remains connection-identity based; a matching generation still passes through the connection identity check (broker.rs:3547–3570). `serve_gen` is copied from the attach request’s req_gen (attach.rs:417–434), NOT the daemon’s generation number.\n\nIf gen1’s serve worker is already dead, no surviving worker must execute this EOF branch. Old server-side connection cleanup is the independent route that releases its controller.\n\n### 4. ConnectionBound opener cleanup\nOn any opener IPC handler exit, broker.rs:6450–6474 first detaches net subscription seats, then for each tracked ConnectionBound stream executes `host.send_stream(id, [], true)`, `host.retire_stream_terminal(id)`, and emits `STREAM_CONNBOUND_RETIRE:<id>`. Both calls are best-effort. Durable opens do not enter this list.\n\nThe target read pump independently translates EOF/error into `StreamLog::finish` (nethost.rs:1144–1157); finish sets finished=true before enqueueing an EOF notification (nethost.rs:519–528). Therefore observing old opener row2 absent and target row1 finished proves transport/lifecycle progress, not completion of the old target controller’s file writes. Opener and old serving worker use different IPC handlers; their cleanup has no global join.\n\n### 5. Poison and delayed cleanup\nPoison does not clear stamps directly. On Windows `poison_and_cancel` latches poison and calls CancelIoEx; `sever` subsequently calls DisconnectNamedPipe plus another CancelIoEx, after canceled I/O completion, so reads fail and handle_conn can reach its exit cleanup (conn.rs:379–435). Writer failure/reaping provides another path: `reap_dead_controller` removes an exited writer in memory, or deferred-stall-evicts a blocked one, then KIND_SESSIONS convergence writes outside the log lock (broker.rs:2779–2821, 6314–6353).\n\nA genuinely idle writer awaiting its channel, whose IPC EOF has not been processed, is not inferred dead by writer-exit polling (broker.rs:2795–2800). Do not transplant ADR-0040’s approximately 65-second real-QUIC silence bound to this in-process duplex case; Amendment 1 explicitly distinguishes these transports.\n\n## Why the exact observed pair is significant\n\n`set_driven_by` and `set_controlled` each call `mutate_info` independently (info.rs:703–715). Each invocation acquires the per-perch sentinel, reads, modifies one field, and writes the full record (info.rs:500–509). Readers remain lock-free (info.rs:485–487). Per-write atomicity prevents torn JSON, but does not make the two-field transition atomic.\n\nThus a normal clear from {controlled:true, driven_by:Some(old)} publishes {controlled:true, driven_by:None} between the two setter calls. File locking, scheduling, and actual writes can expose that intermediate state to a watcher. It can also be a pre-existing local-controller state. Neither interpretation requires gen2 to execute any attach code.\n\n[INFERENCE] Given the supplied 0.29-second body and immediate true/None sample, the highest-value prediction is that the watcher starts without first establishing a post-gen1 cleared baseline and accepts an existing true level as a resurrection. The observed pair specifically fits the middle of the clear path. Source cannot prove that this particular sample was between the setters; it establishes a concrete sufficient mechanism.\n\n## Can the old finished row replay?\n\nThe row types in T2 are expected: class is opener-side. The accepted/duplex peer stays Durable; ADR-0040 Amendment 1 explicitly rejects filtering the served row by class (ADR:240–245). A claimable finished row is NOT already a retired row.\n\nThe dispatch loop captures `s.finished` when enumerating and passes it into worker (dispatch.rs:729–767). Worker first classifies the pinned opener, then calls `finished_row_is_terminal`; finished && Attach returns Served(\"finished attach: terminal, retired unserved\") BEFORE creating the serving Brain or invoking serve_attach (dispatch.rs:1033–1107; discriminator at 573–574). Completion then invokes net_stream_retire (dispatch.rs:778–785).\n\nEligibility retirement hides a row from stream enumeration and opener queries (nethost.rs:1956–1962, 2005–2038, 2079–2085); terminal retirement physically removes it (2053–2071). A physically retained but eligibility-retired row is not replay-eligible. A finished but not yet retired target Attach may still be claimed, but it is retired unserved. This is precisely ADR-0040 Amendment 1:149–160, which warns that the lifecycle-state worker gate, not an enumeration-time finished filter, is the load-bearing exclusion.\n\n[INFERENCE] Because the supplied T2 says row1 was already finished before gen2, the stale-enumeration variant (worker captured unfinished before FIN) is lower-ranked for this observation. It would require a different ordering than the supplied setup. Do not infer actual execution from row1 being claimable or from it remaining Durable.\n\n## Ranked causal predictions and discriminators\n\n1. **Oracle mistakes old/intermediate level for a gen2 edge — strongest.** Prediction: a raw info.json baseline taken after old controller release has completed and before gen2 starts will be false/None; gen2 will not subsequently establish control from row1. A watcher armed while true/None still exists can immediately declare resurrection without any gen2 attach execution.
