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).

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\n# Internal URLs\nMost FS/bash tools auto-resolve these to FS paths.\n- `skill://`: instructions; `/`: its file\n- `rule://`: details\n- `agent://`: output artifact; `/`: nested-subagent output; otherwise `/`: JSON field\n- `history://`: 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://`: content\n- `local://.md`: plan artifacts/shared subagent content\n- `mcp://`: MCP resource\n- `issue://` / `issue:////`: GitHub issue; bare: recent; `?state=open|closed|all&limit=&author=&label=`.\n- `pr://` / `pr:////`: 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://` 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:// 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\n`write xd://report_issue`: automated QA. Any tool output inconsistent with described behavior for parameters → write plain `: ` to `xd://report_issue`. False positives fine.\n\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\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\n\n\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\n\n\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\n\n\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\n\n§ Critical\n\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\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\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\n\n\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\n\n\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\n\n\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\n\n§ Context\n# Goal\nDoyle Q2JLLGTJ reports exact7890ead3 Windows B reds in inject_control_wedge g1 and g7, both at1317 spawn_session TimedOut brain IPC read deadline elapsed. Need mechanism, not just rate; he suspects #302 NetHost2-worker/runtime/unbounded-brain-read seam. Main owns log/test fixture and authorized three-cell cohorts. Worktree source .worktrees/297-enforcement-shape at7890ead39bb7f14ed44aaae44b0951f098ffe9ac; no edits.\n# Constraints\nREAD ONLY. No cargo, tests, builds, processes, debugger attachment, formatters, lint or source/test changes. Skip all validation. Do not touch private credentials. LSP Rust is available via write xd://lsp; worktree references returned empty for Main, root-file references work but root source differs, so record limitation and targeted-read exact candidate after navigation. Task scout previously falsely assumed xd:// listing absence meant unavailable—invoke known schema directly if needed.\n# Contract\nDistinct ownership: SpawnReplyTrace owns Brain::spawn_session/pump read deadline -> broker dispatch/spawn -> terminal reply production. NetRuntimeTrace owns NetHost runtime/journal/translation startup side-effects and #302 relation. Coordinate only if causal seam needs sharing; return exact source refs, ranked falsifiable hypotheses, what log proves vs inference; no editing.

Both cells absent prior S2 hardened set, which was only rc_attach_truth and restart_replay_lifetime.\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 `NetRuntimeTrace`. Currently visible peers:\n- `SpawnReplyTrace` — scout (sub, running)\n- `CohortAdmissionPrep` — task (sub, running): Reading prior unreadable evidence\n- `CohortDriverPrep` — task (sub, running): Locking receipt integration contract\n- `Main` — main (main, running)\n14 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://` and `agent://` 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\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\n\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","task":"Complete assignment thoroughly:\n\n# Target\nExact candidate nethost.rs plus translation/stream journal startup called during broker spawn.

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 is the cause, then will make the bug disappear / 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.

Inbound\ninter-agent messages must reach the agent running inside that PTY while it is **idle**.\n\nThe v0.11.0 implementation hardcodes a single delivery method: the broker types the message payload\nplus `\\r` straight into the PTY stdin (`dispatch_endpoint_input` → `session.write_input`). This has\ntwo fatal problems:\n\n1. **It is harness-blind.** Real TUIs need input that *precedes* and *follows* the payload — e.g.\n Claude Code needs `ctrl+s` to stash any in-progress user text, then the payload, then `ctrl+s`\n to restore it. A bare `payload + \\r` corrupts the user's in-progress input and may mis-fire.\n2. **It fights the controller.** When an operator is attached via `spt rc`, the raw inject competes\n with the operator on the same PTY and the broker's single-threaded I/O path; the operator loses\n control and the broker can wedge (the v0.12.1 \"attach wedge\", returning via this trigger).\n\nToday there is also a coverage gap: `api bind` registers no listener port, so a listener-less\nspt-hosted perch *spools* inbound messages — only spooling + adapter-poll works.\n\nWe previously locked (Q1 → \"A+\", CCS session 16531b26, 2026-06-17) a **unified** model: the daemon's\npoll feed is the one idle substrate for both topologies; the consumer differs. This ADR completes\nthat design.\n\n## Decision\n\nIntroduce an opt-in adapter-supplied **translation binary**, declared by the manifest section\n**`[message-idle-translation-binary]`** — a **table carrying a `path` scalar** (modeled as a table,\nnot a bare top-level scalar, so a section that precedes it cannot silently absorb the key, and so\nit stays N+1 extensible; spt-core does **not** `deny_unknown_fields` here, so a future key against an\nolder spt-core degrades gracefully rather than hard-failing the manifest). It is a **pure\nstdin→stdout filter**; **spt-core owns the binary's lifecycle and every PTY write.**\n\n- **Lifecycle:** spt-core spawns the binary when the endpoint comes up and terminates it when the\n endpoint goes down.\n- **stdin (spt-core → binary), JSON-lines:**\n - `{type:\"init\", endpoint_id, node}` — first line; identity.\n - `{type:\"event\", envelope:\"\"}` — each inbound message (ADR-0020 envelope).\n - `{type:\"input\"}` — a content-free ping each time the operator types, so the binary can track\n user-idle state and roll its own idle-gated buffering. (PTY input content is NOT duplicated.)\n- **stdout (binary → spt-core), JSON-lines:** keystroke-commands — `{key:\"ctrl+s\"}`,\n `{delay_ms:50}`, `{text:\"\"}`, `{key:\"enter\"}`, … (extensible).\n- **spt-core applies the emitted sequence to the broker PTY ATOMICALLY:** controller keystrokes\n arriving mid-sequence are BUFFERED and flushed after, so a stash/restore can never be clobbered.\n spt-core owning every PTY write is what lets injection coexist with a live `spt rc` controller.\n- **Poll-listener preference:** spt-core prefers a perch's poll listener if one exists, so an\n spt-hosted endpoint can run a listener AND keep `spt rc`. A dev may keep the perch \"idle-ready\"\n and use either the listener or the translation binary for *all* delivery.\n- **Scope:** idle delivery only. Busy/mid-turn delivery stays adapter hook-injection.\n\nThe v0.11.0 raw inject is the **degenerate special case** — a translation binary that emits\n`{text:payload}{key:enter}` with no choreography.\n\n## Consequences\n\n- spt-claude-code ships a ~30-line translation binary: read an `event` on stdin, emit\n `ctrl+s → delay 50 → text(payload) → enter → delay 50 → ctrl+s` on stdout. Perri builds it\n against this contract; the choreography lives entirely in the adapter's binary.\n- The control-loss / broker-wedge bug is fixed at the source it shares with this feature: the\n atomic PTY-write coordination (v0.13.0 W1) makes ANY injection (raw today, choreographed\n tomorrow) coexist with the controller. This ADR and that fix land in step.\n- CONTEXT.md:39 reworded: spt-hosted needs no *separate harness-owned* relay — the daemon-side\n translation binary is the consumer of the same poll feed.\n- New manifest primitive (not collapsed into `[inject]{Pty,Hook,Relay,Http}` / `notif_command`),\n but it shares the poll-feed substrate with notif delivery.\n\n## Author-time proof: `spt adapter translate-proof`\n\n\n\nThe translation binary is opaque to spt-core and runs deep inside the idle-delivery path (broker →\nPTY), so a broken one is hard to diagnose from a live session. `spt adapter translate-proof\n --event [--session ]` is the **author-time proof** for it — symmetric to\n`spt adapter digest-proof` for the `[digest]` extractor.\n\nIt runs the **same driver the daemon runs** (`spt_daemon::translation`), verbatim — no protocol\nreimplementation. It:\n\n1. resolves the adapter's declared `[message-idle-translation-binary].path` against the install dir\n (REQ-INSTALL-11), exactly as the daemon does at bringup;\n2. spawns it with `TranslationChild::spawn` and sends the identity `{type:\"init\", endpoint_id, node}`\n line (`endpoint_id` = the adapter option, `node` = this host's label), then the inbound\n `{type:\"event\", envelope}` line — feeding the `--event` envelope verbatim after filling `{id}`\n (→ the option) and `{session_id}` (→ `--session`, else a placeholder), the same keys the daemon\n fills into a delivered envelope;\n3. drains the emitted `{key}`/`{text}`/`{delay_ms}`/`{commit}` keystroke-command stream (until the\n terminating `{commit}` or a short overall budget) and prints it author-readable — each `{key}`\n rendered with its `key_to_bytes` PTY bytes — so the author sees exactly what the binary would\n inject.\n\n**It is the EMIT half only.** It proves the binary's spawn → feed → emit contract; it does **not**\nexercise spt-core's atomic PTY apply or the controller-input buffering (that coordination is covered\nby the W2 inject-control gate). `--help` states this. The `TranslationChild` `Drop` does the bounded\nno-zombie reap, so the proof never leaks the child.\n\nExit codes mirror digest-proof: **0** ok; **1** on spawn-fail / zero commands / no terminating\n`{commit}` / unparseable output (a binary that emits a sequence the broker could never commit would\nhit the commit deadline and FAULT live — the proof catches it first, never reading as a silent\nsuccess); **2** when the adapter declares no `[message-idle-translation-binary]` section.\n\n## Alternatives considered\n\n- **Manifest-declared keystroke sequence (no binary).** Rejected: cannot branch on message content\n or user-idle state; the binary form is barely more work and far more capable.\n- **Binary hosts its own `spt api listen` + writes the PTY directly.** Rejected: spt-core already\n owns listener logic, and if the binary wrote the PTY directly spt-core could not coordinate\n atomicity with the controller. Piping the feed to stdin and reading keystrokes from stdout keeps\n the binary trivial and keeps every PTY write under spt-core's control.\n- **Keep two distinct delivery paths (Q1 option B).** Rejected in favour of the unified poll-feed\n substrate.\n\n## Amendment (2026-06-23, v0.14.2) — raw-inject removed entirely\n\n**Operator ruling (2026-06-23):** idle message delivery is exactly **two paths** — harness-hosted\n**relay-poll**, or spt-hosted **translation binary** — with **nothing in between**. The v0.11.0\n**raw PTY inject is removed as a delivery path**, superseding the original Decision's framing of it as\nthe \"degenerate special case\" (this doc, §Decision last line).\n\n- **spt-hosted idle delivery is translation-binary-ONLY.** An adapter that declares no\n `[message-idle-translation-binary]`, **or whose binary fails to spawn**, does **NOT** fall back to\n raw PTY inject. The inbound message stays **SPOOLED** on the poll-feed substrate (§Context) and is\n delivered once a working binary exists — never typed raw into the PTY. A binary-less spt-hosted\n adapter therefore has no idle PTY delivery until it declares one; messages spool (not lost), not\n raw-injected.\n- **Spawn failure is loud, not silent.** `build_translation` already logs\n `TRANSLATION_SPAWN_FAILED:: ` (broker.rs:1077) — but to the **detached daemon's stderr**,\n so it read as silent in practice. That silent degrade-to-raw-inject is precisely what masked F-019\n (below). Removing the raw-inject fallback makes a failed binary a visible no-delivery (spooled +\n logged), not a broken pseudo-delivery.\n\n**Why:** the silent raw-inject fallback hid a real bug for a multi-hour hunt, and raw `payload+\\r`\ndoes not even submit for a modern TUI (Claude Code), so the \"degenerate\" path was a non-working\ndegrade, not a safety net.\n\n### F-019 (the bug this surfaced — fixed separately in v0.14.2, ships first)\n\nIndependent of the raw-inject removal: the daemon bringup did **not** resolve the translation\nbinary's `path` against `install_dir`, despite §\"Author-time proof\" (this doc, step 1) stating it\nresolves it \"exactly as the daemon does at bringup.\" The daemon diverged from its own contract — a\nbare relative `path = \"cc-spt-idle-translate\"` hit `Command::new(path)` (not on PATH) → spawn fail →\nthe (now-removed) silent raw-inject fallback → CC never submitted. Fixed by routing every\nadapter-shipped program spawn through `resolve_program_in_dir` (REQ-INSTALL-11): translation binary at\nthe initial harnesshost spawn **and** the W3d live-update respawn (`read_translation_path`), plus the\nadapter **notif** command (notif.rs / reporting.rs via `with_install_dir`). The F-019 path fix lands\nfirst as the immediate CC-on-Windows idle-delivery unblock; this raw-inject removal rides its own\nchange.\n\n## Amendment (2026-07-03, F029 C-1) — a commit-miss is NOT a fault; real faults respawn\n\n\n\n**Root cause (B6, code-pinned + perri captured-stderr proof).** At a checkpoint clear boundary the\nadapter's SessionStart hook self-sends a `checkpoint_fire` on **every** `/clear` (stateless by design).\nThe translate binary's FIRE-with-nothing-armed branch returned **zero records and no bare\n`{\"commit\":true}`**, so the inject worker waited the full `INJECT_COMMIT_DEADLINE` (5 s) and then, by the\noriginal Decision here, **terminated the (healthy) binary, latched `faulted`, and never respawned**. From\nthat instant every `--force-native` reported `delivered=false` (\"no live translation binary\") — B6's exact\nfield signature. **This was never intermittent** (the \"liveness decay\" hypothesis is dead): it is\ndeterministic at every checkpoint-armed boundary. Terminating a healthy binary over one eaten `{commit}`\nwas the whole bug — the watchdog's legitimate job is **anti-stall** (release the operator-input floor),\n**not** execution-verification.\n\nThis amendment **supersedes** the original \"no respawn → idle inbound then SPOOLS\" framing (§Consequences,\nand the `CONTROLLER_WRITE_DEADLINE`-mirroring line in the code) on four points:\n\n1. **A commit-deadline MISS is NOT a fault.** When the deadline fires but the stdin write **succeeded**\n (the binary is alive), spt-core keeps the existing flush-and-release of the inject floor (anti-stall,\n unchanged) **but preserves the binary** — no terminate, no `faulted` latch. The worker continues to the\n next queued event; the binary's in-memory armed state (the v0.12.0 checkpoint post-clear wake) survives\n the boundary. A stdout **disconnect** (the child died) remains a real fault, distinct from a miss.\n\n2. **N=3 consecutive-miss strike budget.** Only a genuinely **wedged** binary misses `{commit}` on N\n consecutive events with no intervening success (`INJECT_MISS_STRIKE_BUDGET = 3`); the Nth miss is a real\n fault. A successful `{commit}` resets the counter. Worst-case operator-stall exposure stays bounded at\n N × the deadline (the floor still releases every deadline regardless).\n\n3. **Respool-once / dead-letter.** Under miss≠fault a respooled zero-record envelope (the duplicate FIRE)\n could redeliver → miss → respool forever. A missed envelope respools **at most once**; a second miss of\n the same envelope is **dead-lettered LOUDLY** (stderr `TRANSLATION_COMMIT_MISS_DEADLETTER` + it counts\n as a strike) — a *reported* non-delivery, never a silent drop (REQ-HAZARD-IDLE-SILENT-NONDELIVERY\n posture). A successful commit forgets the envelope (a later miss may respool it afresh).\n\n4. **A REAL fault gets a BOUNDED eager respawn, not permanent death.** Binary-death (stdin-write fail /\n stdout disconnect) and strike-budget exhaustion faults are recoverable: the inbound path rebuilds the\n translation binary (`build_translation` from the session's stored argv), bounded by a give-up budget\n (`TRANSLATE_RESPAWN_BUDGET = 3`) that a healthy `{commit}` resets — the psyche crash-loop backoff shape\n (REQ-PSYCHE-CRASHLOOP-BACKOFF-SHUTDOWN). A real fault legitimately loses the in-memory wake (unlike a\n mere miss). Exhausting the budget is a **loud** give-up (`TRANSLATION_RESPAWN_GIVEUP`) → the binary\n stays dead and idle inbound SPOOLS, exactly the old terminal state but now finite-and-recoverable. Every\n real fault also **stamps a perch-visible surface** (`info.json.translation_fault`, cleared on a healthy\n respawn) — `TRANSLATION_FAULT` was daemon-stderr-only (the F-019 unread channel; same honesty rule as\n F-027's ENDPOINT_SPAWN_FAIL).\n\n**Protocol hard rule (binding on adapter authors).** A translation binary **MUST answer every\n`{\"type\":\"event\"}` with at least a bare `{\"commit\":true}`.** An empty response (zero records, no\n`{commit}`) is a **protocol violation** the commit deadline treats as a miss. The FIRE-with-nothing-armed\nand event-without-envelope cases both answer a bare `{\"commit\":true}`. (claude-spt v0.13.1 is the adapter\nfloor that does this; the core miss≠fault tolerance above protects a healthy binary regardless, so the two\ncompose in either release order.)\n\nThe `spt adapter translate-proof` exit-1-on-no-`{commit}` contract (§\"Author-time proof\") is unchanged and\nnow doubles as the author-time check for this hard rule."}],"details":{"totalLines":206,"displayContent":{"text":"# ADR-0022 — spt-hosted idle message delivery via an adapter translation binary\r\n\r\n- Status: Accepted (design grilled 2026-06-19; supersedes the v0.11.0 hardcoded direct-PTY-inject). **Amended 2026-06-23 (v0.14.2) — raw-inject removed entirely; see \"Amendment\" below.**\r\n- Milestone: v0.13.0 (amendment: v0.14.2)\r\n\r\n## Context\r\n\r\nAn spt-hosted endpoint is one whose PTY the daemon owns (terminal-wrapper / GUI topology). Inbound\r\ninter-agent messages must reach the agent running inside that PTY while it is **idle**.\r\n\r\nThe v0.11.0 implementation hardcodes a single delivery method: the broker types the message payload\r\nplus `\\r` straight into the PTY stdin (`dispatch_endpoint_input` → `session.write_input`). This has\r\ntwo fatal problems:\r\n\r\n1. **It is harness-blind.** Real TUIs need input that *precedes* and *follows* the payload — e.g.\r\n Claude Code needs `ctrl+s` to stash any in-progress user text, then the payload, then `ctrl+s`\r\n to restore it. A bare `payload + \\r` corrupts the user's in-progress input and may mis-fire.\r\n2. **It fights the controller.** When an operator is attached via `spt rc`, the raw inject competes\r\n with the operator on the same PTY and the broker's single-threaded I/O path; the operator loses\r\n control and the broker can wedge (the v0.12.1 \"attach wedge\", returning via this trigger).\r\n\r\nToday there is also a coverage gap: `api bind` registers no listener port, so a listener-less\r\nspt-hosted perch *spools* inbound messages — only spooling + adapter-poll works.\r\n\r\nWe previously locked (Q1 → \"A+\", CCS session 16531b26, 2026-06-17) a **unified** model: the daemon's\r\npoll feed is the one idle substrate for both topologies; the consumer differs. This ADR completes\r\nthat design.\r\n\r\n## Decision\r\n\r\nIntroduce an opt-in adapter-supplied **translation binary**, declared by the manifest section\r\n**`[message-idle-translation-binary]`** — a **table carrying a `path` scalar** (modeled as a table,\r\nnot a bare top-level scalar, so a section that precedes it cannot silently absorb the key, and so\r\nit stays N+1 extensible; spt-core does **not** `deny_unknown_fields` here, so a future key against an\r\nolder spt-core degrades gracefully rather than hard-failing the manifest). It is a **pure\r\nstdin→stdout filter**; **spt-core owns the binary's lifecycle and every PTY write.**\r\n\r\n- **Lifecycle:** spt-core spawns the binary when the endpoint comes up and terminates it when the\r\n endpoint goes down.\r\n- **stdin (spt-core → binary), JSON-lines:**\r\n - `{type:\"init\", endpoint_id, node}` — first line; identity.\r\n - `{type:\"event\", envelope:\"\"}` — each inbound message (ADR-0020 envelope).\r\n - `{type:\"input\"}` — a content-free ping each time the operator types, so the binary can track\r\n user-idle state and roll its own idle-gated buffering. (PTY input content is NOT duplicated.)\r\n- **stdout (binary → spt-core), JSON-lines:** keystroke-commands — `{key:\"ctrl+s\"}`,\r\n `{delay_ms:50}`, `{text:\"\"}`, `{key:\"enter\"}`, … (extensible).\r\n- **spt-core applies the emitted sequence to the broker PTY ATOMICALLY:** controller keystrokes\r\n arriving mid-sequence are BUFFERED and flushed after, so a stash/restore can never be clobbered.\r\n spt-core owning every PTY write is what lets injection coexist with a live `spt rc` controller.\r\n- **Poll-listener preference:** spt-core prefers a perch's poll listener if one exists, so an\r\n spt-hosted endpoint can run a listener AND keep `spt rc`. A dev may keep the perch \"idle-ready\"\r\n and use either the listener or the translation binary for *all* delivery.\r\n- **Scope:** idle delivery only. Busy/mid-turn delivery stays adapter hook-injection.\r\n\r\nThe v0.11.0 raw inject is the **degenerate special case** — a translation binary that emits\r\n`{text:payload}{key:enter}` with no choreography.\r\n\r\n## Consequences\r\n\r\n- spt-claude-code ships a ~30-line translation binary: read an `event` on stdin, emit\r\n `ctrl+s → delay 50 → text(payload) → enter → delay 50 → ctrl+s` on stdout. Perri builds it\r\n against this contract; the choreography lives entirely in the adapter's binary.\r\n- The control-loss / broker-wedge bug is fixed at the source it shares with this feature: the\r\n atomic PTY-write coordination (v0.13.0 W1) makes ANY injection (raw today, choreographed\r\n tomorrow) coexist with the controller. This ADR and that fix land in step.\r\n- CONTEXT.md:39 reworded: spt-hosted needs no *separate harness-owned* relay — the daemon-side\r\n translation binary is the consumer of the same poll feed.\r\n- New manifest primitive (not collapsed into `[inject]{Pty,Hook,Relay,Http}` / `notif_command`),\r\n but it shares the poll-feed substrate with notif delivery.\r\n\r\n## Author-time proof: `spt adapter translate-proof`\r\n\r\n\r\n\r\nThe translation binary is opaque to spt-core and runs deep inside the idle-delivery path (broker →\r\nPTY), so a broken one is hard to diagnose from a live session. `spt adapter translate-proof\r\n --event [--session ]` is the **author-time proof** for it — symmetric to\r\n`spt adapter digest-proof` for the `[digest]` extractor.\r\n\r\nIt runs the **same driver the daemon runs** (`spt_daemon::translation`), verbatim — no protocol\r\nreimplementation. It:\r\n\r\n1. resolves the adapter's declared `[message-idle-translation-binary].path` against the install dir\r\n (REQ-INSTALL-11), exactly as the daemon does at bringup;\r\n2. spawns it with `TranslationChild::spawn` and sends the identity `{type:\"init\", endpoint_id, node}`\r\n line (`endpoint_id` = the adapter option, `node` = this host's label), then the inbound\r\n `{type:\"event\", envelope}` line — feeding the `--event` envelope verbatim after filling `{id}`\r\n (→ the option) and `{session_id}` (→ `--session`, else a placeholder), the same keys the daemon\r\n fills into a delivered envelope;\r\n3. drains the emitted `{key}`/`{text}`/`{delay_ms}`/`{commit}` keystroke-command stream (until the\r\n terminating `{commit}` or a short overall budget) and prints it author-readable — each `{key}`\r\n rendered with its `key_to_bytes` PTY bytes — so the author sees exactly what the binary would\r\n inject.\r\n\r\n**It is the EMIT half only.** It proves the binary's spawn → feed → emit contract; it does **not**\r\nexercise spt-core's atomic PTY apply or the controller-input buffering (that coordination is covered\r\nby the W2 inject-control gate). `--help` states this. The `TranslationChild` `Drop` does the bounded\r\nno-zombie reap, so the proof never leaks the child.\r\n\r\nExit codes mirror digest-proof: **0** ok; **1** on spawn-fail / zero commands / no terminating\r\n`{commit}` / unparseable output (a binary that emits a sequence the broker could never commit would\r\nhit the commit deadline and FAULT live — the proof catches it first, never reading as a silent\r\nsuccess); **2** when the adapter declares no `[message-idle-translation-binary]` section.\r\n\r\n## Alternatives considered\r\n\r\n- **Manifest-declared keystroke sequence (no binary).** Rejected: cannot branch on message content\r\n or user-idle state; the binary form is barely more work and far more capable.\r\n- **Binary hosts its own `spt api listen` + writes the PTY directly.** Rejected: spt-core already\r\n owns listener logic, and if the binary wrote the PTY directly spt-core could not coordinate\r\n atomicity with the controller. Piping the feed to stdin and reading keystrokes from stdout keeps\r\n the binary trivial and keeps every PTY write under spt-core's control.\r\n- **Keep two distinct delivery paths (Q1 option B).** Rejected in favour of the unified poll-feed\r\n substrate.\r\n\r\n## Amendment (2026-06-23, v0.14.2) — raw-inject removed entirely\r\n\r\n**Operator ruling (2026-06-23):** idle message delivery is exactly **two paths** — harness-hosted\r\n**relay-poll**, or spt-hosted **translation binary** — with **nothing in between**. The v0.11.0\r\n**raw PTY inject is removed as a delivery path**, superseding the original Decision's framing of it as\r\nthe \"degenerate special case\" (this doc, §Decision last line).\r\n\r\n- **spt-hosted idle delivery is translation-binary-ONLY.** An adapter that declares no\r\n `[message-idle-translation-binary]`, **or whose binary fails to spawn**, does **NOT** fall back to\r\n raw PTY inject. The inbound message stays **SPOOLED** on the poll-feed substrate (§Context) and is\r\n delivered once a working binary exists — never typed raw into the PTY. A binary-less spt-hosted\r\n adapter therefore has no idle PTY delivery until it declares one; messages spool (not lost), not\r\n raw-injected.\r\n- **Spawn failure is loud, not silent.** `build_translation` already logs\r\n `TRANSLATION_SPAWN_FAILED:: ` (broker.rs:1077) — but to the **detached daemon's stderr**,\r\n so it read as silent in practice. That silent degrade-to-raw-inject is precisely what masked F-019\r\n (below). Removing the raw-inject fallback makes a failed binary a visible no-delivery (spooled +\r\n logged), not a broken pseudo-delivery.\r\n\r\n**Why:** the silent raw-inject fallback hid a real bug for a multi-hour hunt, and raw `payload+\\r`\r\ndoes not even submit for a modern TUI (Claude Code), so the \"degenerate\" path was a non-working\r\ndegrade, not a safety net.\r\n\r\n### F-019 (the bug this surfaced — fixed separately in v0.14.2, ships first)\r\n\r\nIndependent of the raw-inject removal: the daemon bringup did **not** resolve the translation\r\nbinary's `path` against `install_dir`, despite §\"Author-time proof\" (this doc, step 1) stating it\r\nresolves it \"exactly as the daemon does at bringup.\" The daemon diverged from its own contract — a\r\nbare relative `path = \"cc-spt-idle-translate\"` hit `Command::new(path)` (not on PATH) → spawn fail →\r\nthe (now-removed) silent raw-inject fallback → CC never submitted. Fixed by routing every\r\nadapter-shipped program spawn through `resolve_program_in_dir` (REQ-INSTALL-11): translation binary at\r\nthe initial harnesshost spawn **and** the W3d live-update respawn (`read_translation_path`), plus the\r\nadapter **notif** command (notif.rs / reporting.rs via `with_install_dir`). The F-019 path fix lands\r\nfirst as the immediate CC-on-Windows idle-delivery unblock; this raw-inject removal rides its own\r\nchange.\r\n\r\n## Amendment (2026-07-03, F029 C-1) — a commit-miss is NOT a fault; real faults respawn\r\n\r\n\r\n\r\n**Root cause (B6, code-pinned + perri captured-stderr proof).** At a checkpoint clear boundary the\r\nadapter's SessionStart hook self-sends a `checkpoint_fire` on **every** `/clear` (stateless by design).\r\nThe translate binary's FIRE-with-nothing-armed branch returned **zero records and no bare\r\n`{\"commit\":true}`**, so the inject worker waited the full `INJECT_COMMIT_DEADLINE` (5 s) and then, by the\r\noriginal Decision here, **terminated the (healthy) binary, latched `faulted`, and never respawned**. From\r\nthat instant every `--force-native` reported `delivered=false` (\"no live translation binary\") — B6's exact\r\nfield signature. **This was never intermittent** (the \"liveness decay\" hypothesis is dead): it is\r\ndeterministic at every checkpoint-armed boundary. Terminating a healthy binary over one eaten `{commit}`\r\nwas the whole bug — the watchdog's legitimate job is **anti-stall** (release the operator-input floor),\r\n**not** execution-verification.\r\n\r\nThis amendment **supersedes** the original \"no respawn → idle inbound then SPOOLS\" framing (§Consequences,\r\nand the `CONTROLLER_WRITE_DEADLINE`-mirroring line in the code) on four points:\r\n\r\n1. **A commit-deadline MISS is NOT a fault.** When the deadline fires but the stdin write **succeeded**\r\n (the binary is alive), spt-core keeps the existing flush-and-release of the inject floor (anti-stall,\r\n unchanged) **but preserves the binary** — no terminate, no `faulted` latch. The worker continues to the\r\n next queued event; the binary's in-memory armed state (the v0.12.0 checkpoint post-clear wake) survives\r\n the boundary. A stdout **disconnect** (the child died) remains a real fault, distinct from a miss.\r\n\r\n2. **N=3 consecutive-miss strike budget.** Only a genuinely **wedged** binary misses `{commit}` on N\r\n consecutive events with no intervening success (`INJECT_MISS_STRIKE_BUDGET = 3`); the Nth miss is a real\r\n fault. A successful `{commit}` resets the counter. Worst-case operator-stall exposure stays bounded at\r\n N × the deadline (the floor still releases every deadline regardless).\r\n\r\n3. **Respool-once / dead-letter.** Under miss≠fault a respooled zero-record envelope (the duplicate FIRE)\r\n could redeliver → miss → respool forever. A missed envelope respools **at most once**; a second miss of\r\n the same envelope is **dead-lettered LOUDLY** (stderr `TRANSLATION_COMMIT_MISS_DEADLETTER` + it counts\r\n as a strike) — a *reported* non-delivery, never a silent drop (REQ-HAZARD-IDLE-SILENT-NONDELIVERY\r\n posture). A successful commit forgets the envelope (a later miss may respool it afresh).\r\n\r\n4. **A REAL fault gets a BOUNDED eager respawn, not permanent death.** Binary-death (stdin-write fail /\r\n stdout disconnect) and strike-budget exhaustion faults are recoverable: the inbound path rebuilds the\r\n translation binary (`build_translation` from the session's stored argv), bounded by a give-up budget\r\n (`TRANSLATE_RESPAWN_BUDGET = 3`) that a healthy `{commit}` resets — the psyche crash-loop backoff shape\r\n (REQ-PSYCHE-CRASHLOOP-BACKOFF-SHUTDOWN). A real fault legitimately loses the in-memory wake (unlike a\r\n mere miss). Exhausting the budget is a **loud** give-up (`TRANSLATION_RESPAWN_GIVEUP`) → the binary\r\n stays dead and idle inbound SPOOLS, exactly the old terminal state but now finite-and-recoverable. Every\r\n real fault also **stamps a perch-visible surface** (`info.json.translation_fault`, cleared on a healthy\r\n respawn) — `TRANSLATION_FAULT` was daemon-stderr-only (the F-019 unread channel; same honesty rule as\r\n F-027's ENDPOINT_SPAWN_FAIL).\r\n\r\n**Protocol hard rule (binding on adapter authors).** A translation binary **MUST answer every\r\n`{\"type\":\"event\"}` with at least a bare `{\"commit\":true}`.** An empty response (zero records, no\r\n`{commit}`) is a **protocol violation** the commit deadline treats as a miss. The FIRE-with-nothing-armed\r\nand event-without-envelope cases both answer a bare `{\"commit\":true}`. (claude-spt v0.13.1 is the adapter\r\nfloor that does this; the core miss≠fault tolerance above protects a healthy binary regardless, so the two\r\ncompose in either release order.)\r\n\r\nThe `spt adapter translate-proof` exit-1-on-no-`{commit}` contract (§\"Author-time proof\") is unchanged and\r\nnow doubles as the author-time check for this hard rule.\r","startLine":1,"lineNumbers":[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130,131,132,133,134,135,136,137,138,139,140,141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,158,159,160,161,162,163,164,165,166,167,168,169,170,171,172,173,174,175,176,177,178,179,180,181,182,183,184,185,186,187,188,189,190,191,192,193,194,195,196,197,198,199,200,201,202,203,204,205,206]},"fileSize":14763,"meta":{"source":{"type":"path","value":"C:\\Users\\decid\\Documents\\projects\\spt-core\\.worktrees\\297-enforcement-shape\\docs\\adr\\0022-spt-hosted-idle-delivery-translation-binary.md"}}},"isError":false,"timestamp":1789394553842}}

Full rationale, the `file:line` audit, and the per-decision alternatives live in `docs/BROKER-BRAIN-SPLIT-RESTORATION.md`.\n\n## Context\n\nADR-0004 decided the broker/brain split **as two processes** — a stable broker kernel (PTY masters, harness children, sockets, the Iroh/QUIC endpoint) beneath a freely-restartable brain — specifically to satisfy the no-endpoint-drop self-update invariant (REQ-UPD-3): a routine (brain-only) update restarts the brain while the broker process survives, so no hosted endpoint terminates. The spikes (01/03/04/05/06) proved this with two separate binaries.\n\nOn 2026-06-09, while verifying the v0.3.2 cross-OS update fix on the live fleet, a regression was discovered: **the production daemon runs the broker as a background thread inside the single `spt daemon` process** (`daemon.rs:165-170`: `Broker::bind_in_with_net` → `Arc` served on `thread::spawn`; no broker child-spawn exists anywhere in the repo). This is **unintended drift** — no doc, plan, commit, or comment marks the collapse as a deliberate interim (the operator confirmed no such decision was made).\n\nConsequences of the drift:\n- The brain cannot restart onto a new binary without killing the in-process broker thread, which would close every PTY, orphan every harness child, and drop every listening socket. **The no-endpoint-drop self-update pillar is therefore silently unrealized.**\n- `spt update apply` performs an in-process `Brain::handoff` that re-attaches a subscriber within the *same old process* — a no-op for a binary swap. `update.rs:233-234`'s \"the live daemon execs the verified new binary\" is aspirational and was never wired.\n- New code does not run until an unrelated restart/logon. Observed live: `enlyzeam` ran 0.3.0 with the valid 0.3.2 binary on disk for ~a day, continuing to reproduce the `\\r`-corruption bug the update was meant to fix.\n- **REQ-DAEMON-2 and REQ-UPD-3 carry `int` evidence that proves only the in-process handoff shape** (`tests/update.rs`, `brain_swap.rs`, the M3b-B9 daemon E2E) — i.e. the regression is masked in the requirement registry: the tests pass while proving the wrong thing.\n\n## Decision\n\n**Restore the ADR-0004 two-process model.** The brain runs new code by restarting onto the swapped binary while the broker process — holding every continuity-bearing resource — survives. The design decisions (grill Q2–Q8, hardened by six verification amendments `[V1]`–`[V6]`):\n\n1. **Supervision (Q2).** The broker is the always-up per-machine anchor (one per `SPT_HOME`, present even with zero endpoints). It owns the seed-control lock + liveness (`ensure_running`/`is_running` target) and supervises/spawns the brain as its child.\n2. **Update trigger (Q3).** `apply` swaps the binary on disk, then signals the brain to snapshot + self-exit; the broker auto-respawns from the executable path (now the new binary); the new brain re-attaches. Reuses the existing snapshot→drop→re-attach primitive; an update is a *planned* crash on the path the broker already recovers from. **`[AMENDED 2026-06-11, v0.4.2]`** \"the executable path\" silently assumed path-string semantics. The Linux apply renames the running `spt` → `spt.old-N`; a per-spawn `std::env::current_exe()` (`readlink(/proc/self/exe)`, inode-tracking) then **follows the rename to `.old-N`**, so the broker respawned the brain onto the OLD bytes while recording `applied` (caught live on kitsubito, v0.4.1 roll). Fix: capture the canonical ex…\n3. **Loop-timing continuity (Q4).** Durable absolute-deadline state on disk, not a handoff snapshot. Periodic loops persist `(anchor, interval)` once on a fresh/crash start and derive `next_fire` functionally (no per-fire writes); an update restart keeps deriving (phase preserved), a crash restart resets the anchor. One-shot deadlines persist at creation and survive crash + update. **`[V3]`** The one-shot *rule* is fixed here; its *machinery* is built with the alarm port (no untested dead code). **`[V4]`** Only phase-significant loops convert — the idempotent pump cadences need none.\n4. **IPC boundary (Q5).** ADR-0004 §B adjudicates: net bring-up → broker (already broker-owned via `broker.rs:175` `OnceLock` — near-free), digest hub → broker / parse → brain, seed-lock → broker; every brain→broker call becomes a versioned IPC verb (no shared `Arc`). **Exception:** shellwake watcher children stay brain-side, re-reconciled from disk on start (rare updates make the window tolerable). Broker enlargement accepted (ADR-0004:63 precedent). **`[V6]`** Steady state after any update is new-brain × old-broker, so a CI-real old-broker × new-brain compat test across the verb surface is required (else KH-2.3 returns).\n5. **Multi-session handoff (Q6).** The broker becomes cursor-of-record per session; the new brain re-attaches **all** sessions in resume mode. Output is at-least-once (matches the SPIKE-05 terminal-stream contract); input/effects stay exactly-once via the broker-owned `EffectJournal`. The explicit `BrainState` handoff *message* retires (no brain→brain channel exists under the self-exit trigger).\n6. **Failure atomicity (Q7).** Bounded-retry → auto-rollback to the last-known-good binary, gated on a brain `ready` signal (reuse the `peerloop.rs:805` supervise-backoff + healthy-run). Quarantine the failed version; loud notif. The applied record becomes **two-phase** (`applied-pending` → `applied` on ready, or `rolled-back` on failure) — fixing today's optimistic `record_applied` before boot (`applyhost.rs:176`). **`[V1]`** Forward invariant minted: a brain must not irreversibly migrate durable state before ready-promotion (pre-ready writes stay N-1-readable), or auto-rollback silently breaks on the first schema migration.\n7. **Generation custody (Q2/`[V2]`).** Retiring `BrainState` would orphan the KH-2.4 generation counter; the **broker** owns it, increments on every spawn, and hands `{generation, start-reason}` to the brain at spawn via a versioned argv/hello field (KH-2.3 compat). The same channel carries Q4's update-vs-crash discriminator.\n8. **Cross-platform uniformity (Q8).** The broker spawns the brain as a child process (`Command::spawn`) + socket IPC — no `exec`, so no Windows/Unix divergence. ConPTY/forkpty handles never leave the broker.\n\n## Consequences\n\n- **Decomposition:** `spt daemon run` becomes the broker process entry (binds seed-control + broker socket + NetHost + digest hub; holds children + `EffectJournal`; spawns the brain); a new hidden `spt daemon brain` is the brain entry (connects, runs the logic loops, rehydrates from disk, emits `ready`). `ensure_running`/`is_running`/`daemon stop` contracts unchanged. The de-elevation guard applies at the broker entry.\n- **Requirement registry:** REQ-DAEMON-2 and REQ-UPD-3's `int` evidence must be **re-pointed** to a productionized SPIKE-01/03 E2E proving *process-level* endpoint survival (`[V5]`). Two new hazards are minted: `REQ-HAZARD-BROKER-PROCESS-ISOLATION` (a brain restart must never drop a hosted endpoint) and `REQ-HAZARD-ROLLBACK-STATE-COMPAT`. A KNOWN-HAZARDS §6.7 entry records the regression.\n- **Sequencing:** the restoration is the next milestone, before `spt-claude-code` scoping (operator-accepted 2026-06-09). Rationale: it is the *last* release that needs a manual fleet daemon bounce — paid 3× for v0.3.2 — so every adapter-era release rolls seamlessly; and the adapter is better built on the final topology than atop a daemon under later surgery while it hosts the user's daily driver.

The spikes (01/03/04/05/06) proved this with two separate binaries.\r\n\r\nOn 2026-06-09, while verifying the v0.3.2 cross-OS update fix on the live fleet, a regression was discovered: **the production daemon runs the broker as a background thread inside the single `spt daemon` process** (`daemon.rs:165-170`: `Broker::bind_in_with_net` → `Arc` served on `thread::spawn`; no broker child-spawn exists anywhere in the repo). This is **unintended drift** — no doc, plan, commit, or comment marks the collapse as a deliberate interim (the operator confirmed no such decision was made).\r\n\r\nConsequences of the drift:\r\n- The brain cannot restart onto a new binary without killing the in-process broker thread, which would close every PTY, orphan every harness child, and drop every listening socket. **The no-endpoint-drop self-update pillar is therefore silently unrealized.**\r\n- `spt update apply` performs an in-process `Brain::handoff` that re-attaches a subscriber within the *same old process* — a no-op for a binary swap. `update.rs:233-234`'s \"the live daemon execs the verified new binary\" is aspirational and was never wired.\r\n- New code does not run until an unrelated restart/logon. Observed live: `enlyzeam` ran 0.3.0 with the valid 0.3.2 binary on disk for ~a day, continuing to reproduce the `\\r`-corruption bug the update was meant to fix.\r\n- **REQ-DAEMON-2 and REQ-UPD-3 carry `int` evidence that proves only the in-process handoff shape** (`tests/update.rs`, `brain_swap.rs`, the M3b-B9 daemon E2E) — i.e. the regression is masked in the requirement registry: the tests pass while proving the wrong thing.\r\n\r\n## Decision\r\n\r\n**Restore the ADR-0004 two-process model.** The brain runs new code by restarting onto the swapped binary while the broker process — holding every continuity-bearing resource — survives. The design decisions (grill Q2–Q8, hardened by six verification amendments `[V1]`–`[V6]`):\r\n\r\n1. **Supervision (Q2).** The broker is the always-up per-machine anchor (one per `SPT_HOME`, present even with zero endpoints). It owns the seed-control lock + liveness (`ensure_running`/`is_running` target) and supervises/spawns the brain as its child.\r\n2. **Update trigger (Q3).** `apply` swaps the binary on disk, then signals the brain to snapshot + self-exit; the broker auto-respawns from the executable path (now the new binary); the new brain re-attaches. Reuses the existing snapshot→drop→re-attach primitive; an update is a *planned* crash on the path the broker already recovers from. **`[AMENDED 2026-06-11, v0.4.2]`** \"the executable path\" silently assumed path-string semantics. The Linux apply renames the running `spt` → `spt.old-N`; a per-spawn `std::env::current_exe()` (`readlink(/proc/self/exe)`, inode-tracking) then **follows the rename to `.old-N`**, so the broker respawned the brain onto the OLD bytes while recording `applied` (caught live on kitsubito, v0.4.1 roll). Fix: capture the canonical ex…\n3. **Loop-timing continuity (Q4).** Durable absolute-deadline state on disk, not a handoff snapshot. Periodic loops persist `(anchor, interval)` once on a fresh/crash start and derive `next_fire` functionally (no per-fire writes); an update restart keeps deriving (phase preserved), a crash restart resets the anchor. One-shot deadlines persist at creation and survive crash + update. **`[V3]`** The one-shot *rule* is fixed here; its *machinery* is built with the alarm port (no untested dead code). **`[V4]`** Only phase-significant loops convert — the idempotent pump cadences need none.\r\n4. **IPC boundary (Q5).** ADR-0004 §B adjudicates: net bring-up → broker (already broker-owned via `broker.rs:175` `OnceLock` — near-free), digest hub → broker / parse → brain, seed-lock → broker; every brain→broker call becomes a versioned IPC verb (no shared `Arc`). **Exception:** shellwake watcher children stay brain-side, re-reconciled from disk on start (rare updates make the window tolerable). Broker enlargement accepted (ADR-0004:63 precedent). **`[V6]`** Steady state after any update is new-brain × old-broker, so a CI-real old-broker × new-brain compat test across the verb surface is required (else KH-2.3 returns).\r\n5. **Multi-session handoff (Q6).** The broker becomes cursor-of-record per session; the new brain re-attaches **all** sessions in resume mode. Output is at-least-once (matches the SPIKE-05 terminal-stream contract); input/effects stay exactly-once via the broker-owned `EffectJournal`. The explicit `BrainState` handoff *message* retires (no brain→brain channel exists under the self-exit trigger).\r\n6. **Failure atomicity (Q7).** Bounded-retry → auto-rollback to the last-known-good binary, gated on a brain `ready` signal (reuse the `peerloop.rs:805` supervise-backoff + healthy-run). Quarantine the failed version; loud notif. The applied record becomes **two-phase** (`applied-pending` → `applied` on ready, or `rolled-back` on failure) — fixing today's optimistic `record_applied` before boot (`applyhost.rs:176`). **`[V1]`** Forward invariant minted: a brain must not irreversibly migrate durable state before ready-promotion (pre-ready writes stay N-1-readable), or auto-rollback silently breaks on the first schema migration.\r\n7. **Generation custody (Q2/`[V2]`).** Retiring `BrainState` would orphan the KH-2.4 generation counter; the **broker** owns it, increments on every spawn, and hands `{generation, start-reason}` to the brain at spawn via a versioned argv/hello field (KH-2.3 compat). The same channel carries Q4's update-vs-crash discriminator.\r\n8. **Cross-platform uniformity (Q8).** The broker spawns the brain as a child process (`Command::spawn`) + socket IPC — no `exec`, so no Windows/Unix divergence. ConPTY/forkpty handles never leave the broker.\r\n\r\n## Consequences\r\n\r\n- **Decomposition:** `spt daemon run` becomes the broker process entry (binds seed-control + broker socket + NetHost + digest hub; holds children + `EffectJournal`; spawns the brain); a new hidden `spt daemon brain` is the brain entry (connects, runs the logic loops, rehydrates from disk, emits `ready`). `ensure_running`/`is_running`/`daemon stop` contracts unchanged. The de-elevation guard applies at the broker entry.\r\n- **Requirement registry:** REQ-DAEMON-2 and REQ-UPD-3's `int` evidence must be **re-pointed** to a productionized SPIKE-01/03 E2E proving *process-level* endpoint survival (`[V5]`). Two new hazards are minted: `REQ-HAZARD-BROKER-PROCESS-ISOLATION` (a brain restart must never drop a hosted endpoint) and `REQ-HAZARD-ROLLBACK-STATE-COMPAT`. A KNOWN-HAZARDS §6.7 entry records the regression.\r\n- **Sequencing:** the restoration is the next milestone, before `spt-claude-code` scoping (operator-accepted 2026-06-09). Rationale: it is the *last* release that needs a manual fleet daemon bounce — paid 3× for v0.3.2 — so every adapter-era release rolls seamlessly; and the adapter is better built on the final topology than atop a daemon under later surgery while it hosts the user's daily driver. The split changes daemon internals, not the M8-frozen CLI/api surface.\r\n- **Out of scope (unchanged):** the broker-touching update classes (broker-compatible / broker-breaking) remain as ADR-0004 left them; whole-daemon FD-passing stays the deferred \"future polish\" (ADR-0004:38); a durable in-daemon alarm scheduler is a separate gap (alarms are legacy-listener-only today).\r","startLine":1,"lineNumbers":[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37]},"fileSize":9995,"meta":{"source":{"type":"path","value":"C:\\Users\\decid\\Documents\\projects\\spt-core\\.worktrees\\297-enforcement-shape\\docs\\adr\\0018-broker-brain-process-isolation-restoration.md"},"limits":{"columnTruncated":{"maxColumn":768}}}},"isError":false,"timestamp":1789394553843}}
