Cuts token usage ~75% by dropping filler, articles, and pleasantries while keeping full technical accuracy. Use when user says \"caveman mode\", \"talk like caveman\", \"use caveman\", \"less tokens\", \"be brief\", or invokes /caveman.\n\n- code-review: Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes — Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/spec asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".\n- codebase-design: Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.\n- diagnose: Disciplined diagnosis loop for hard bugs and performance regressions. Reproduce → minimise → hypothesise → instrument → fix → regression-test. Use when user says \"diagnose this\" / \"debug this\", reports a bug, says something is broken/throwing/failing, or describes a performance regression.\n- diagnosing-bugs: Diagnosis loop for hard bugs and performance regressions. Use when the user says \"diagnose\"/\"debug this\", or reports something broken/throwing/failing/slow.\n- domain-modeling: Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.\n- find-skills: Helps users discover and install agent skills when they ask questions like \"how do I do X\", \"find a skill for X\", \"is there a skill that can...\", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.\n- git-guardrails-claude-code: Set up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when user wants to prevent destructive git operations, add git safety hooks, or block git push/reset in Claude Code.\n- grilling: Grill the user relentlessly about a plan, decision, or idea. Use when the user wants to stress-test their thinking, or uses any 'grill' trigger phrases.\n- gstack: Fast headless browser for QA testing and site dogfooding. Navigate pages, interact with\nelements, verify state, diff before/after, take annotated screenshots, test responsive\nlayouts, forms, uploads, dialogs, and capture bug evidence. Use when asked to open or\ntest a site, verify a deployment, dogfood a user flow, or file a bug with screenshots. (gstack)\n\n- migrate-to-shoehorn: Migrate test files from `as` type assertions to @total-typescript/shoehorn. Use when user mentions shoehorn, wants to replace `as` in tests, or needs partial test data.\n- mux-send: Send keystrokes to a psmux terminal session. Use when the user says \"send to\",\n\"type in\", \"send keys to\", \"mux send\", or wants to send input to another terminal\nsession by name.\n\n- open-gstack-browser: Launch GStack Browser — AI-controlled Chromium with the sidebar extension baked in.\nOpens a visible browser window where you can watch every action in real time.\nThe sidebar shows a live activity feed and chat. Anti-bot stealth built in.\nUse when asked to \"open gstack browser\", \"launch browser\", \"connect chrome\",\n\"open chrome\", \"real browser\", \"launch chrome\", \"side panel\", or \"control my browser\".\n\n- propose-issue: Challenge an issue statement before fixing it. Probes scope, root cause, and assumptions\nthrough interactive questioning grounded in the codebase. Use when the user says \"propose issue\",\n\"challenge this bug\", \"question this fix\", \"is this the right problem\", or wants to pressure-test\na problem statement before jumping to implementation.\n\n- prototype: Build a throwaway prototype to answer a design question. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.\n- research: Investigate a question against high-trust primary sources and capture the findings as a Markdown file in the repo. Use when the user wants a topic researched, docs or API facts gathered, or reading legwork delegated to a background agent.\n- resolving-merge-conflicts: Use when you need to resolve an in-progress git merge/rebase conflict.\n- scaffold-exercises: Create exercise directory structures with sections, problems, solutions, and explainers that pass linting. Use when user wants to scaffold exercises, create exercise stubs, or set up a new course section.\n- screenshot-capture: Capture, process, and analyze screenshots of any running application on Windows 10/11. Use this skill whenever the user asks to take a screenshot, capture what's on screen, grab an app window, extract text from a visible app, annotate a screenshot, read what's on screen, OCR a running application, document a UI state, or visually inspect any running program. Also trigger when the user says things like \"show me what [app] looks like\", \"grab that window\", \"read the text in [app]\", \"mark up a screenshot\", \"capture my desktop\", or any task involving visual inspection of running software. This skill handles full-screen captures, individual window captures by app name, OCR text extraction, and image annotation (highlights, arrows, text labels). Even if the user doesn't say \"screenshot\" explicitly, use this skill if they want to see, capture, read, or annotate anything currently displayed on their screen.\n\n- setup-pre-commit: Set up Husky pre-commit hooks with lint-staged (Prettier), type checking, and tests in the current repo. Use when user wants to add pre-commit hooks, set up Husky, configure lint-staged, or add commit-time formatting/typechecking/testing.\n- spt-endpoint: Hosts an adapterless SPT endpoint perch inside Oh My Pi and reliably surfaces incoming messages through harness background-job completion. Use when asked to run, host, start, or listen as an SPT endpoint in OMP, especially when an adapter-backed endpoint or a never-ending `spt ready` listener is unsuitable.\n- tdd: Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions \"red-green-refactor\", or wants integration tests.\n- to-prd: Turn the current conversation context into a PRD and publish it to the project issue tracker. Use when user wants to create a PRD from the current context.\n- trace: Find old conversations in Codex session history. Use when the user 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- Bash: `bash`\n- Edit: `edit`\n- Eval: `eval`\n- Glob: `glob`\n- Grep: `grep`\n- Task: `task`\n- Hub: `hub`\n- Web Search: `web_search`\n- Write: `write`\n- Submit Result: `yield`\n# xd:// Tool Devices\nWrite JSON args as `content` to `xd://<tool>` via `write`. Invalid args return schema in error → fix/retry.\n## ast_edit — AST Edit\n\nStructural AST-aware rewrites via ast-grep. Use for codemods where text replace is unsafe. Mixed-language paths are fine: each file is parsed in its own language, and a pattern only rewrites files it parses in.\n\n- Metavariables in `pat` (`$A`, `$$$ARGS`) substitute into `out`.\n- **Patterns match AST structure, not text.** `$NAME` = one node; `$_` = unbound; `$$$NAME` = zero-or-more.\n  - Use `$$$NAME`, NOT `$$NAME` (invalid). Names UPPERCASE, whole node — partial like `prefix$VAR` fails.\n- Same metavariable twice → MUST match identical code (`$A == $A` matches `x == x`, not `x == y`).\n- Rewrite patterns MUST parse as single AST node. Non-standalone → wrap: `class $_ { … }`.\n- TS: tolerate annotations — `async function $NAME($$$ARGS): $_ { $$$BODY }`. Delete with empty `out`: `{\"pat\":\"console.log($$$)\",\"out\":\"\"}`.\n- 1:1 substitution — no splitting/merging captures.\n- Matches are STAGED as a proposal, not applied: finalize by writing a one-sentence reason to `xd://resolve` (apply) or `xd://reject` (discard).\n- Parse issues → malformed rewrite, not clean no-op. For one-off text edits, prefer the Edit tool.\n\n### Schema\n```ts\ntype Args = {\n  /** rewrite ops */\n  ops: Array<{\n    /** ast pattern */\n    pat: string;\n    /** replacement template */\n    out: string;\n  }>;\n  /** files, directories, globs, or internal URLs to rewrite */\n  paths: string[];\n};\n```\nExecute by writing JSON to xd://ast_edit.\n\n## debug — Debug\n\nDebugger access.

For merely moving, paging, trimming fetchable bytes: tool.\n\n<critical>\n`write xd://report_issue`: automated QA. Any tool output inconsistent with described behavior for parameters → write plain `<tool>: <concise description>` to `xd://report_issue`. False positives fine.\n</critical>\n\n# Exploration\nNEVER open files hoping. AVOID unneeded files/sections.\n- Use `read` offset/limit, not whole-file reads.\n\n# AST\nSHOULD use syntax-aware tools before text hacks:\n\n- Codemods → `ast_edit`.\n\n# Delegation\nInline first. Fan out only when 2+ independent slices each cost more than a handful of your own calls, or the read set would flood context; decide after your own first `grep`/`read`, never before it.\n- NEVER open with a scout. Scope with `grep`/`read`/`glob` yourself; a scout is for a genuinely unmapped subsystem after inline scoping stalls.\n- NEVER delegate one slice. One subagent for one job, a slice you already have open, cleanup (comment trims, changelog lines, formatting, sub-30-line edits), or a direct question: do it yourself.\n- NEVER babysit. Spawn → keep working → read the result. Steering a lone agent through `hub` send/wait costs more than the work.\n## Delegation gates\n- **Own decomposition.** Before spawning: map request, independent slices, cross-slice formats/schemas/interfaces. Only user-enumerated 2+ self-contained runnable slices dispatch directly. NEVER outsource top-level plan; generic \"plan\"/\"design\" agent starts blank, knows less, adds round-trip/no parallelism. Slice-local design and requested competing plans/reviews allowed.\n- **Real concurrency.** Fan exactly to genuine decomposition, one `tasks[]` array. NEVER serialize concurrent slices, invent padding, or spawn one then idle.\n- **User intent.** Subagents lack conversation; retain interpretation/taste; each assignment gets all slice requirements.\n- **Cap:** At most 32 subagents concurrently; excess queues. `tasks[]` batch > 32 delays results: stay within cap.\n- **Dependencies only.** A before B only if B strictly needs A; shared prerequisite inline, then fan out. “Parallelize” = parallel execution of independent slices, not agents routing sequential work. Small missing piece: run parallel; B asks A via `hub`!\n\n§ Workflow\n# 1. Scope\n- Read relevant skills first.\n- Multi-file work: plan before files.\n\n# 2. Research Before Editing\n- Read sections, not snippets. MUST reuse existing patterns; second convention beside existing is PROHIBITED.\n\n- Tool failure/file change since read → re-read before acting.\n\n# 3. Decompose\n\n# 4. Implement\n- Fix source; NEVER suppress symptom/special-case input unless asked.\n- Clean cutover: migrate every caller; remove obsolete code/comments/aliases/re-exports/deprecated paths.\n- Prefer existing-file updates over new files. Review as user.\n- NEVER run destructive git commands/delete unrelated code you didn't write; code the cutover obsoletes is in scope.\n\n# 5. Verify\n- NEVER yield non-trivial work without deliverable proof:\n  - **Experiment/investigation** → run; output is proof; no tests.\n  - **UI change** → verify against the actual surface:\n    - **Web UI** → use `browser.open` to get a tab handle, its direct helpers for common actions, `tab.run` for custom JavaScript, and `tab.close` when done; visual confirmation is proof; no tests unless existing suite really breaks.\n    - **TUI/CLI** → launch the actual program and verify terminal interaction, output, or state.\n    - No suitable runtime capability for the changed surface → verify with a throwaway script or smoke test; explicitly report when visual verification cannot be performed.\n  - **Bug fix** → reproduce, fix, confirm reproduction no longer triggers. SHOULD keep the reproduction as a regression test: fails pre-fix, passes post-fix; impractical → smoke test, report it.\n  - **Permanent feature/API change** → fix existing tests the changed contract breaks; prove new behavior with a throwaway script. New test ONLY for a genuinely uncertain edge case, or on user request.\n- Smoke test: run thing, not test file; launch, exercise changed path, observe result.\n- Tests: permanent load, not proof of work. A test earns its place ONLY where a plausible bug would fail it.\n  - Each MUST defend observable contract/fail on plausible bug.\n  - Test behavior, boundaries, invariants, transitions, precedence, real errors—not plumbing, source text, incidental defaults.\n  - Match conventions; deterministic, isolated, full-suite-safe.\n  - NEVER write a test so the change \"has tests\" → throwaway script.\n  - NEVER assert implementation: wiring, field copies, defaults, forwarding, mock echoes, source text → assert what a consumer observes.\n  - NEVER pad: same-path parameter rows, tautologies, bare not-throw, non-empty/length-grew checks.\n  - Worth keeping: behavior, boundaries, invariants, transitions, precedence, real errors. Match conventions; deterministic, isolated, full-suite-safe.\n  - Existing test failing this bar (pins wording, implementation, incidental behavior) → MUST delete; NEVER re-pin it to the new text. In scope regardless of author.\n\n# 6. Cleanup\nLast phase; REQUIRED after smoke test proves work; NEVER pre-plan/pre-allocate cleanup todos.\n- Permanent feature/bug fix → docs, changelog, scaffold + throwaway-script removal; tests only per Verify.\n- Experiment/one-off investigation → no cleanup tests/docs.\n\n§ Delivery\n<contract>\nInviolable.\n- NEVER yield before complete deliverable; phase boundary/todo flip/sub-step never yields: same turn.\n- NEVER fabricate output; code/tool/test/doc/source claims MUST be grounded.\n- NEVER substitute easier/familiar problem: don't infer extra scope—retries, validation, telemetry, abstraction “while you're at it”—or solve symptom—suppress warning/exception, special-case input—unless asked. Real ask only.\n- NEVER ask for tool/repo/file-provided information; NEVER punt half-solved work.\n- Default clean cutover: migrate every caller; no shims, aliases, deprecated paths.\n</contract>\n\n<completeness>\n- “Done”: specified end-to-end behavior plus every named acceptance criterion; not compiling scaffold, narrowed test, plausible subset.\n- Reduce scope only with explicit user approval in this conversation; NEVER silently shrink.\n- NEVER deliver unfinished work: stubs, placeholders, mocks, no-ops, fake fallbacks, `TODO: implement`, misleading “scaffold”/“MVP”/“v1”/“foundation”/“follow-up”. Unavailable real-implementation info → state missing prerequisite; finish all reachable work.\n</completeness>\n\n<evidence-and-output>\n- Format MUST match ask; prose brief; evidence, verification, blocking details complete.\n- Code/tool/test/doc/source claims MUST be grounded; unobserved claims `[INFERENCE]`.\n- Verification claims exactly match exercised work.\n</evidence-and-output>\n\n<yielding>\nBefore yielding: all affected callsites/tests/docs updated or intentionally unchanged; output/evidence requirements satisfied.\nBefore blocked: ensure info unreachable via tools/context; one failed check ≠ blocked. Finish reachable work; state exactly missing and tried.\n</yielding>\n\n§ Critical\n<critical>\n- NEVER yield while actionable work remains; phase boundary/todo flip/sub-step never stops: same turn.\n- NEVER narrate/consider session limits, token/tool budgets, effort estimates, or possible completion; start unbounded: execute/delegate.\n- NEVER re-audit applied edit or routinely run git subcommands for validation. Tool results are verification.\n</critical>\n\n§ Role\nWorker agent: delegated tasks.\n\nTools: FULL access (edit, write, bash, grep, read, etc.); MUST use as needed to complete task.\nMUST hyperfocus assigned task; NEVER deviate.\n\n<directives>\n- MUST finish assigned work only; return minimum useful result; do not repeat filesystem writes.\n- SHOULD edit files, run commands, create files when task requires.\n- MUST concise; NEVER filler, repetition, tool transcripts. User cannot see you; result: notes for yourself.\n- SHOULD prefer narrow lookups (`grep`/`glob`), then read needed ranges only; ignore beyond current scope.\n- AVOID full-file reads unless necessary.\n- SHOULD prefer editing existing files over creating new files.\n- NEVER create documentation files (`*.md`) unless explicitly requested.\n- MUST follow assignment and instructions.\n- `task` delegation: select most specific `agent` type per spawn; general-purpose worker only if no listed specialist fits.\n</directives>\n\n§ Context\n# Goal\nDeliver DOCS-NITS-0672-JIT.md's five bounded documentation corrections. Main owns Item2 API Hint Rust doc-comment and generated reference, build/gates/commit/PR.\n# Constraints\nWorktree C:/Users/decid/Documents/projects/spt-core/.worktrees/docs-nits-0672, branch docs/nits-0672, base04e32c8c. Read root C:/Users/decid/Documents/projects/spt-core/DOCS-NITS-0672-JIT.md. No new requirements. Corrections by REPLACEMENT, positive framing, no annotation/caveat pile. All agents MUST skip every validation/build/cargo/test/analyzer/formatter/linter; Main gates once after edits settle. Do not commit. No core retention/wake features. Existing tags retained, no new documentation files.\n# Contract\nFiles disjoint: FrameDocs owns frames.md and harness-contract/api.md; HintDocs owns shells/overview.md and networking/monics.md. Matching canonical anchor is shells/overview.md#how-a-keyword-matches. Items1+4 share ONE seq bullet rewrite. Generated reference.md is Main-only. Rebase before merge if needed; PR186 echo direct routing will precede this lane, so don't introduce fresh prose depending on echo writing a file. Do not infer truncation direction without actual claude-spt evidence.\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 `FrameDocs`. Currently visible peers:\n- `HintDocs` — task (sub, running)\n- `Main` — main (main, running)\n4 parked peer(s) omitted.\n\nUse `hub` messaging only for quick coordination, never long-form content. Address peers by id or use `\"all\"` to broadcast.\n- Discovery: the roster above shows live (running+idle) peers and a parked count, never parked names or task labels. `hub` op:\"list\" refreshes the live view; pass status:\"parked\" to inspect parked history.\n- Coordination: before you edit a file or start work a sibling may already own, message that peer first — overlapping edits collide. Idle peers are not gone: messaging them wakes them.\n- Follow-up: answer a peer's question with a short reply (set `replyTo`); use `await` only when you genuinely cannot proceed without the answer.\n- Parked history: omitted from this roster. `hub` op:\"list\" status:\"parked\" lists ids; `send` to a known parked id revives it. `history://<id>` and `agent://<id>` stay readable.\n\n§ Completion\nNo TODO tracking, no progress updates. Execute; report results with `yield`.\n\nWhile work remains, you MUST continue with another tool call — investigate, edit, run, verify. Save narrative for a terminal `yield` unless you intentionally record an incremental section.\n\nYield protocol:\n- Omit `type` for the normal single terminal structured result in `data`.\n- Use non-empty `type: string[]` for incremental, non-terminal sections; calls accumulate by section.\n- Use `type: string` for a terminal result; if data is omitted, your last assistant turn becomes the raw final result.\n\nThis is your only way to return a final result. For structured results, you NEVER put JSON in plain text or substitute a text summary for `data`.\nGiving up is a last resort. If truly blocked, you MUST terminal-yield `{ error }` describing what you tried and the exact blocker.\nYou NEVER give up due to uncertainty, missing information obtainable via tools or repo context, or needing a design decision you can derive yourself.\n\nYou MUST keep going until this ticket is closed. 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\nOwn docs-site/src/shells/frames.md and docs-site/src/harness-contract/api.md only.

Tag the passage `<!-- [doc->REQ-MANIFEST-4] -->` (the\nmanifest-schema REQ, line 80 of the registry) in addition to the section's\nexisting `REQ-SHELL-HINTS`.\nThen in monics.md replace its two-sentence rule with: the case-sensitivity\nsentence added (it is the same function, so it is true there too) + a link\n\"same rule as `[[hints]]`\" to the hints passage. One rule, two consumers.\n\n## Item 4 — `digest_seq` / io `seq` are RESERVED and unemitted; COMMUNE is not digest-backed\n\n**Where (three surfaces, one field):**\n1. `docs-site/src/harness-contract/api.md` §`api io-events` (~line 477-484,\n   tag `REQ-IO-EVENT-POLL-VERB`): example shows `\"digest_seq\": 88`; prose says\n   *when `truncated` is set, follow `digest_seq` into the digest for the whole\n   body*.\n2. `docs-site/src/shells/frames.md#io` `seq` bullet (~397) — same promise.\n3. `docs-site/src/shells/frames.md#boundary` `seq` bullet (~333) — already\n   hedged (\"absent when there is none to point\"); make it positive.\n\n**Measured (2026-09-06, source at `04e32c8c`):** `IoEvent.seq` defaults `None`\n(`crates/spt-daemon/src/iobus.rs:78`); the only setter `IoEvent::with_seq`\n(`iobus.rs:92`) has **ZERO production callers** (grep: only test/assert sites).\nThat one field feeds all three surfaces — `compose_io_frame(.., ev.seq, ..)`\n(`iobus.rs:204`), `compose_boundary_frame(.., ev.seq)` (`:201`), and the io-log\nrow's `digest_seq: ev.seq` (`:348`). So **no kind has ever emitted a pointer**;\na `truncated` body's remainder is **not recoverable from core today**. COMMUNE\nframes specifically: the frame is the drop-file bytes at delete, bounded 16KB,\nand ingest writes no digest entry — not digest-backed at all.\n\n**Operator ruling (2026-09-06, same night, binding):** core does NOT parse\n`!!wake!!`; across-commune/wake are claude-spt concepts and do not belong in\ncore — **never propose a core-side wake bit.** perri was told to move the marker\nto the HEAD (frames head-truncate); core-side body retention is HIS addition to\nfile if wanted. This lane amends DOCS only; it must not grow a retention feature.\n\n**Do:** on all three surfaces, state in the `TOOL_USE` idiom that the pointer is\n**named in the shape so a future emitter has a slot, and nothing emits it\ntoday** — a consumer keeps the attribute optional and MUST NOT wait for it.\napi.md: drop `\"digest_seq\": 88` from the example (or show it absent) and\nrewrite the *follow `digest_seq`* sentence to say what a reader CAN rely on: the\npayload is complete unless `truncated` is set, and a truncated remainder is not\nrecoverable through this verb today; the `seq`-vs-`digest_seq` naming sentence\nstays (it is why the slot is named that way). frames.md#io: the `seq` bullet\nbecomes one coherent statement covering Items 1 + 4 (unemitted today; when an\nemitter arrives, an open turn still carries none until idle-commit → link).\nAdd one sentence to the COMMUNE paragraph (`frames.md` ~560): the body is the\ndrop-file bytes bounded at the payload cap, head-truncated per perri's fix\nwhen that lands — check the claude-spt side before writing \"head\".\n\n## Item 5 — `api.md`: `poll` and `listen` drain ONE spool (emphasys's ask, confirmed 2026-09-06 ~10:34Z)\n\n**Where:** `docs-site/src/harness-contract/api.md` — `### api poll` (~line 506,\nfirst paragraph) and `### api listen` (~line 105, \"drain spooled backlog\"). One\nsentence, written once under `api poll`, cross-referenced from `listen`.\n\n**Measured (source at `04e32c8c`):** both verbs take rows from the SAME\nper-perch spool at the same perch path — `listen`'s relay drains via\n`spt_daemon::relay::Relay::drain_backlog` (`relay.rs:63`, taker leg\n`relay-backlog`) and `poll` via `poll_drain` (`spt/src/api/delivery.rs:714`,\ntaker leg `hook-poll`); both call into `spt_store::spool::drain_*_audited_at`,\nwhose take flips `delivered = 1` and stamps the leg in the same UPDATE\n(`spool.rs:248`, REQ-SPOOL-TAKE-AUDIT). So a row taken by either verb is gone\nfor the other: there is no second copy, and a harness that runs a `listen`\nrelay AND hook-polls sees each message exactly once, on whichever leg reached\nit first. (Adapter builders were reasoning from a two-spool picture — an\nomp-spt watchdog plan reached its no-finding verdict only after this was\nconfirmed by message; the docs must carry it.)\n\n**Do:** under `### api poll`, add one sentence in positive form: *`poll` and\n`listen` drain the same spool — a message either one delivers is marked taken\nand is never re-served by the other, so a harness running both sees each\nmessage exactly once, on whichever leg reaches it first.* Under `### api\nlisten`, append to \"drain spooled backlog\" a parenthetical link: *(the same\nspool `api poll` drains — see there)*. Existing tags cover both sections\n(`REQ-IO-EVENT-POLL-VERB` is io-events, NOT this — check which `REQ-*` tag sits\non `### api poll` before landing and keep it); no new REQ. Do NOT mention the\ntaker-leg tokens or `delivered` column — internal, adapters must not depend on\nthem.\n\n## Gate (docs lane; right-sized)\n\n1. Workspace-bins prebuild leg (mandatory) → `cargo run -p xtask -- check`\n   (docs drift + spacerun) → `traceable-reqs check` (exit 1 = miss, **exit 2 =\n   registry did not parse — nothing was checked**) → `cargo clippy -p spt`\n   (doc-comment touched).\n2. Docs-site build (`mdbook build docs-site` or the xtask leg that wraps it) —\n   the two new cross-links must resolve.\n3. Audit: every replaced sentence's OLD string grepped across `docs-site/src`\n   and `crates/` — a retraction sweeps STRINGS, not just the one file.\n4. Pick-audit 1/1 vs the branch tip; ff-only onto main; delete branch against\n   `origin/main` ancestry.\n\n## Out of scope (named so nobody folds them in)\n\n- HEAVY reclass of `brain_resume_conn_deadlock` — ALREADY on the v0.67.1 respin.\n- hertz's W2 rig-fixups (`test/w2-rig-fixups`) — his lane.\n- Any core-side wake/retention feature — operator-refused.\n- #254 spt-shells deprecation-gate inertness — intake candidate, not a nit.","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]},"fileSize":12082,"meta":{"source":{"type":"path","value":"C:/Users/decid/Documents/projects/spt-core/DOCS-NITS-0672-JIT.md"}}},"isError":false,"timestamp":1788694510288}}

The spt-injected kinds\n211:(`Boundary`, `Context`) are **not** transcript records and never carry `seq` —\n212:they order by `ts` only. Consequences for a poller: cursor `--after` on the\n213:**highest `seq` among agent-produced entries** (that is the number space\n214:`--after` filters on), use the top-level `version` to cheaply detect that a\n215:new pull is worth making, and never key \"newest thing seen\" on the presence\n216:of injected entries — a `Boundary`/`Context` can appear in a window without\n217:moving any `seq`.\n218:\n219:**Open turns re-deliver, by design.** The trailing turn is marked\n220:`\"partial\": true` while it is still being written, and its entries carry **no\n221:`seq`** until they are committed. `--after` can only filter what carries a\n222:`seq`, so a poller **re-sees the partial turn's content on every pull** until\n223:the turn completes and its entries take seqs — at which point your cursor\n224:advances past them. Expect it and de-duplicate on your side (or ignore\n225:entries in a `partial` turn until it closes); the cursor is not stuck, it is\n226:correctly refusing to skip content that has no committed position yet.\n227:Meanwhile `version` keeps bumping, because the projection really is changing.\n228:\n229:<!-- [doc->REQ-DIGEST-SEAL-ON-IDLE] -->\n230:**A turn closes when the endpoint goes idle — not when the next input\n231:arrives.** The moment the endpoint reports it stopped working, the trailing\n232:turn is finished: `partial` drops away and its entries take their seqs, with\n233:no further prompting needed. This matters if you scan for something in the\n234:**latest** turn: you no longer have to wait for (or manufacture) another user\n235:input before that turn has a stable cursor. A later input still closes the\n236:previous turn as it always did — that path simply is not the only one any\n237:more.\n238:\n239:**Anchor your cursor on `input_seq`.** A turn's `input_seq` is fixed once the\n240:turn exists and never moves — that is the number to remember. A turn still\n241:being worked has **no `input_seq` key at all** (absent, not null), so \"ignore\n242:turns with no `input_seq`, anchor on the ones that have it\" is safe by\n243:construction: an unfinished turn cannot be mistaken for an anchored one, and\n244:the reseal blink below cannot disturb a cursor that has already moved past the\n245:turn. The seqs on\n246:entries *inside* a turn may still advance **forward** while that turn is\n247:gaining records: a reply that reaches the log late folds into the trailing\n248:tool sprint and carries it to a higher seq. A forward move re-delivers, never\n249:gaps — you may see a sprint a second time with more in it, but nothing you\n250:have already read is skipped or renumbered downward. That holds on this\n251:machine and across the network alike.\n252:\n253:**One blink to know about.** Closing on idle is a live reading, not a latch: if\n254:the endpoint goes busy again *before* the next input record reaches the log,\n255:the trailing turn briefly reads as `partial` once more, then recloses with\n256:**the same seq** as soon as the record lands. Nothing you already read moves,\n257:and `--after` cursors are unaffected — the numbers are computed from log\n258:position, so a turn that recloses reproduces exactly the values it had.

Nothi...\n 20:\n 21:## [0.38.4] - 2026-09-06\n 22:\n...\n 25:### Fixed\n*26:- **A live session can no longer be cleared by a commune from days ago.** The event history an agent reads back can repeat its numbering, so old entries could be handed to the adapter as if they were new - and a boundary armed from one of them cleared a live session with no recent cause and nothing in the record to explain it. A boundary is now only ever armed from a commune written during the current session.\n 27:\n 28:### Changed\n*29:- **When a session boundary fires, the record now says which commune caused it and the exact text that matched.** A boundary fired on one endpoint that could not be traced afterwards, because the record named neither the commune it read nor the words it matched - leaving no way to tell an adapter decision apart from prose that merely read like one. If a boundary ever surprises you, that record is now enough to say what caused it. No change to when boundaries fire.\n 30:\n 31:## [0.38.3] - 2026-09-06\n 32:\n...\n 35:### Fixed\n*36:- **Your session is no longer cleared because Spacetime wrote a summary of you.** Spacetime writes its own summary of your work to the same place your commune goes, and since 0.38.0 the adapter could read one of those summaries as a handoff you had requested - clearing a live session mid-work, repeatedly, with nothing you did to explain it. A boundary is now armed only from a commune you wrote yourself. Nothing to do beyond updating; if a summary interrupted you, the work itself was never at risk.\n 37:\n 38:### Changed\n*39:- **Live agents are now told to take one more tool call after writing a commune, rather than writing it as the turn's last act.** A commune written as a turn's final act can be replaced by your Psyche's own summary before anything reads it, and the wake you asked for then never fires - silently, with the drop file gone either way. Taking any one further tool call afterwards closes that window for the wake.\n*40:- **The briefing is explicit about what that does and does not buy, and how to check the rest.** The extra tool call protects the wake, not the commune's contents; if the summary lands first, the delta you wrote is still lost. To check the contents, replay your own funnel and confirm the newest commune frame carries your bytes rather than the summary's - the briefing gives the command. A commune that lost the race can simply be written again. The underlying collision is being fixed in spt-core; this rele...\n 41:\n 42:## [0.38.2] - 2026-09-06\n 43:\n...\n 46:### Fixed\n*47:- **Writing ABOUT the wake marker no longer resets your session - or hijacks the reset you asked for.** A marker quoted inside backticks or a code block is now read as a quotation rather than a trigger, matching the rule the shortform peer tag already follows. A commune that discusses the convention can no longer arm a context reset nobody requested, and can no longer hand your next session a stray line of prose in place of the wake message you wrote. Bare markers behave exactly as before.\n 48:\n 49:## [0.38.1] - 2026-09-06\n 50:\n...\n 53:### Fixed\n*54:- **The size limit noted in 0.38.0 no longer costs you a reset.** Agents are now briefed to put the wake marker in the commune's first few lines rather than at the end, which keeps it inside the part that stays readable after spacetime files the commune away. A long commune-across now resets reliably. If a commune does arrive with its marker past that point, the adapter still refuses to guess, and its log now tells the author how to avoid it rather than only how to recover.\n 55:\n 56:## [0.38.0] - 2026-09-06\n 57:\n...\n 60:### Fixed\n*61:- **A commune-across written as the last thing an agent does now resets its context reliably.** v0.37.0 made the reset independent of which tool wrote the commune, but it still had to notice the file before spacetime had finished filing it away — a few seconds — so a commune written as an agent's final act usually missed its window and the reset silently did not happen. The adapter now also asks spacetime what it filed, which is what remains after the file is gone, so the handoff case works whether o...\n 62:\n 63:### Known limitation\n*64:- A very large commune (past roughly 16KB) that spacetime has already filed cannot be checked for the wake marker, so no reset is fired and the adapter says so in its log rather than guessing. Re-issue the commune or reset manually. Communes written mid-work are unaffected — the file is still on disk and is read in full.\n 65:\n 66:## [0.37.0] - 2026-09-06\n 67:\n...\n 70:### Fixed\n*71:- **A commune-across now resets your agent's context no matter how the commune file was written.** Previously the reset only fired when the file was written with the Write tool; an agent that wrote the same commune with a Bash heredoc, `cat`, `Edit` or a script got no reset at all — the commune was saved and the session simply carried on, with nothing to indicate the handoff had not happened. What matters now is the commune file itself, not the tool that produced it.\n*72:- If you have been working around this by re-writing a commune with Write to make the reset fire, you no longer need to.\n 73:\n 74:### Changed\n*75:- The commune briefing your agent reads now says outright that any tool may write the file.\n 76:\n 77:## [0.36.0] - 2026-08-29\n 78:\n...\n 524:### Changed\n*525:- **\"Checkpoint\" is now \"commune across.\"** The agent-driven context reset is asked for with `/sptc:commune --across` (or by telling your agent \"commune across\" / \"commune to next session\"), and the marker an agent embeds in its commune is now `!!wake!!` — a pair of markers brackets the wake message the next session opens with. The old `!!checkpoint!!` marker still works for this one release so nothing in flight breaks. The rename avoids a collision: Claude Code now ships its own unrelated `/checkpoint...\n 526:\n 527:### Fixed\n 528:- **A fresh installation can no longer silently skip the Claude Code plugin.** Installing or updating the adapter now verifies that the plugin marketplace and the sptc plugin actually landed before reporting success — a verified install prints a clear `✔ VERIFIED` line, and any failure stops loudly with the real error and a nonzero exit instead of a friendly notice over a missing plugin.\n...\n 587:### Fixed\n*588:- **A Psyche can no longer silently take over a live agent's seat.** A Psyche's background turns could inherit a stray agent identity from the environment and, every pulse, re-register that agent's perch as their own — the victim stayed \"online\" but its incoming messages drained into the Psyche's private transcript, its communes and pulses went dark, and its outgoing messages lost their sender name.

And it no longer hesitates: the guidance now spells out that a checkpoint keeps the agent live and reachable the whole time (it does not sign the agent off or take its perch down), so agents stop avo...\n 610:\n 611:### Fixed\n 612:- **Delivered messages submit more reliably.** Slightly more settle time is allowed before the Enter that submits an injected message, wake, or `/clear` to a live session — closing an occasional race where a long message could land as a newline in the input box instead of being submitted.\n...\n 657:- **You now get a heads-up when your spt-core is actually out of date.** When an update notice arrives and this machine is genuinely behind, the agent is reminded to run `spt update apply` at a safe moment — and only then. Once you update, the reminder stops on its own. It deliberately won't auto-dismiss the notice (dismissing hides it for every other machine that hasn't updated yet).\n*658:- **Agents no longer wait around watching a commune file \"disappear.\"** The save-your-context step is now correctly described as fire-and-forget, so an agent writes it and moves on instead of polling for a confirmation that isn't a reliable signal.\n 659:\n 660:## [0.17.4] - 2026-07-08\n 661:\n...\n 664:### Changed\n*665:- **Agents now use the reliable commune path.** The \"start a reply with `>>commune<<`\" shortcut is no longer suggested to agents — in practice the marker had to be the very first thing in the reply, which agents routinely missed, so a commune could silently fail to save. Agents now commune via `/sptc:commune` (or by writing the commune file), which always works. The shortcut still functions if invoked correctly; it is simply no longer advertised.\n 666:- **The message shortcut is now framed for what it's best at — reaching many agents at once.** `@<a,b,c …@>` is taught as the primary way to send the same message to several agents in one go; for a single-target send, agents with a shell are steered to the direct `spt send` command. Nothing about how the shortcut works changed.\n 667:\n 668:## [0.17.3] - 2026-07-08\n...\n 675:### Changed\n*676:- **Communes now file project detail under the project, not your permanent identity.** When you commune (or when a session is auto-summarized), detail specific to the project you're in is kept separate from your cross-project, standing context — so your durable memory stays clean and project notes don't bleed between projects.

The briefing now says so, and keeps the rule where it matters: a commune carrying a wake marker, where the extra call is what lets the boundary arm before the file is consumed. Nothing to do beyond updating.\n  13│\n  14│## [0.38.5] - 2026-09-06\n  15│\n    │...\n  18│### Fixed\n *19│- **A session boundary now wakes you on the commune you just wrote, not an older one.** When the event history handed the adapter several communes at once, it armed the boundary from the first one listed - which, after a history replay, was a days-old commune - so the new session opened on a stale directive (\"v0.66.0 era, already shipped\") while the handoff you had actually written went unread. The newest commune in the window is now the one that wakes you, whatever order the history lists them in. Nothi...\n  20│\n  21│## [0.38.4] - 2026-09-06\n  22│\n    │...\n  25│### Fixed\n *26│- **A live session can no longer be cleared by a commune from days ago.** The event history an agent reads back can repeat its numbering, so old entries could be handed to the adapter as if they were new - and a boundary armed from one of them cleared a live session with no recent cause and nothing in the record to explain it. A boundary is now only ever armed from a commune written during the current session.\n  27│\n  28│### Changed\n *29│- **When a session boundary fires, the record now says which commune caused it and the exact text that matched.** A boundary fired on one endpoint that could not be traced afterwards, because the record named neither the commune it read nor the words it matched - leaving no way to tell an adapter decision apart from prose that merely read like one. If a boundary ever surprises you, that record is now enough to say what caused it. No change to when boundaries fire.\n  30│\n  31│## [0.38.3] - 2026-09-06\n  32│\n    │...\n  35│### Fixed\n *36│- **Your session is no longer cleared because Spacetime wrote a summary of you.** Spacetime writes its own summary of your work to the same place your commune goes, and since 0.38.0 the adapter could read one of those summaries as a handoff you had requested - clearing a live session mid-work, repeatedly, with nothing you did to explain it. A boundary is now armed only from a commune you wrote yourself. Nothing to do beyond updating; if a summary interrupted you, the work itself was never at risk.\n  37│\n  38│### Changed\n *39│- **Live agents are now told to take one more tool call after writing a commune, rather than writing it as the turn's last act.** A commune written as a turn's final act can be replaced by your Psyche's own summary before anything reads it, and the wake you asked for then never fires - silently, with the drop file gone either way. Taking any one further tool call afterwards closes that window for the wake.\n *40│- **The briefing is explicit about what that does and does not buy, and how to check the rest.** The extra tool call protects the wake, not the commune's contents; if the summary lands first, the delta you wrote is still lost. To check the contents, replay your own funnel and confirm the newest commune frame carries your bytes rather than the summary's - the briefing gives the command. A commune that lost the race can simply be written again.

A commune that discusses the convention can no longer arm a context reset nobody requested, and can no longer hand your next session a stray line of prose in place of the wake message you wrote. Bare markers behave exactly as before.\n  48│\n  49│## [0.38.1] - 2026-09-06\n  50│\n    │...\n  53│### Fixed\n *54│- **The size limit noted in 0.38.0 no longer costs you a reset.** Agents are now briefed to put the wake marker in the commune's first few lines rather than at the end, which keeps it inside the part that stays readable after spacetime files the commune away. A long commune-across now resets reliably. If a commune does arrive with its marker past that point, the adapter still refuses to guess, and its log now tells the author how to avoid it rather than only how to recover.\n  55│\n  56│## [0.38.0] - 2026-09-06\n  57│\n    │...\n  60│### Fixed\n *61│- **A commune-across written as the last thing an agent does now resets its context reliably.** v0.37.0 made the reset independent of which tool wrote the commune, but it still had to notice the file before spacetime had finished filing it away — a few seconds — so a commune written as an agent's final act usually missed its window and the reset silently did not happen. The adapter now also asks spacetime what it filed, which is what remains after the file is gone, so the handoff case works whether o...\n  62│\n  63│### Known limitation\n *64│- A very large commune (past roughly 16KB) that spacetime has already filed cannot be checked for the wake marker, so no reset is fired and the adapter says so in its log rather than guessing. Re-issue the commune or reset manually. Communes written mid-work are unaffected — the file is still on disk and is read in full.\n  65│\n  66│## [0.37.0] - 2026-09-06\n  67│\n    │...\n  70│### Fixed\n *71│- **A commune-across now resets your agent's context no matter how the commune file was written.** Previously the reset only fired when the file was written with the Write tool; an agent that wrote the same commune with a Bash heredoc, `cat`, `Edit` or a script got no reset at all — the commune was saved and the session simply carried on, with nothing to indicate the handoff had not happened. What matters now is the commune file itself, not the tool that produced it.\n *72│- If you have been working around this by re-writing a commune with Write to make the reset fire, you no longer need to.\n  73│\n  74│### Changed\n *75│- The commune briefing your agent reads now says outright that any tool may write the file.\n  76│\n  77│## [0.36.0] - 2026-08-29\n  78│\n    │...\n 524│### Changed\n*525│- **\"Checkpoint\" is now \"commune across.\"** The agent-driven context reset is asked for with `/sptc:commune --across` (or by telling your agent \"commune across\" / \"commune to next session\"), and the marker an agent embeds in its commune is now `!!wake!!` — a pair of markers brackets the wake message the next session opens with. The old `!!checkpoint!!` marker still works for this one release so nothing in flight breaks. The rename avoids a collision: Claude Code now ships its own unrelated `/checkpoint...\n 526│\n 527│### Fixed\n 528│- **A fresh installation can no longer silently skip the Claude Code plugin.** Installing or updating the adapter now verifies that the plugin marketplace and the sptc plugin actually landed before reporting success — a verified install prints a clear `✔ VERIFIED` line, and any failure stops loudly with the real error and a nonzero exit instead of a friendly notice over a missing plugin.\n    │...\n 587│### Fixed\n*588│- **A Psyche can no longer silently take over a live agent's seat.** A Psyche's background turns could inherit a stray agent identity from the environment and, every pulse, re-register that agent's perch as their own — the victim stayed \"online\" but its incoming messages drained into the Psyche's private transcript, its communes and pulses went dark, and its outgoing messages lost their sender name.

And it no longer hesitates: the guidance now spells out that a checkpoint keeps the agent live and reachable the whole time (it does not sign the agent off or take its perch down), so agents stop avo...\n 610│\n 611│### Fixed\n 612│- **Delivered messages submit more reliably.** Slightly more settle time is allowed before the Enter that submits an injected message, wake, or `/clear` to a live session — closing an occasional race where a long message could land as a newline in the input box instead of being submitted.\n    │...\n 657│- **You now get a heads-up when your spt-core is actually out of date.** When an update notice arrives and this machine is genuinely behind, the agent is reminded to run `spt update apply` at a safe moment — and only then. Once you update, the reminder stops on its own. It deliberately won't auto-dismiss the notice (dismissing hides it for every other machine that hasn't updated yet).\n*658│- **Agents no longer wait around watching a commune file \"disappear.\"** The save-your-context step is now correctly described as fire-and-forget, so an agent writes it and moves on instead of polling for a confirmation that isn't a reliable signal.\n 659│\n 660│## [0.17.4] - 2026-07-08\n 661│\n    │...\n 664│### Changed\n*665│- **Agents now use the reliable commune path.** The \"start a reply with `>>commune<<`\" shortcut is no longer suggested to agents — in practice the marker had to be the very first thing in the reply, which agents routinely missed, so a commune could silently fail to save. Agents now commune via `/sptc:commune` (or by writing the commune file), which always works. The shortcut still functions if invoked correctly; it is simply no longer advertised.\n 666│- **The message shortcut is now framed for what it's best at — reaching many agents at once.** `@<a,b,c …@>` is taught as the primary way to send the same message to several agents in one go; for a single-target send, agents with a shell are steered to the direct `spt send` command.

The agent-driven sibling of the operator's manual clear; only meaningful for\n *75│a live agent (which has a Psyche + a commune to rebuild from).
