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 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\nImplement W1 of handed-file milestone #318 for releases#317: quoted-span path extraction, emitted-line dedupe, and evidence-backed RCA of duplicate helper records. Main owns decomposition/integration, helperline.rs extractor/tests, traceable-reqs.toml, docs/changelog, all native validation and Git/PR operations. Worktree C:/Users/decid/Documents/projects/spt-core/.worktrees/317-quoted-span-paths; branch fix/317-quoted-span-paths; base b33aedcae51fa5ffa840ef1b36c9989a25884bdc.\n# Constraints\nNo builds, Cargo, tests, linters or formatters; no cargo fmt. Skip ALL validation. Do not commit, alter live data, contact external fleet peers, or inspect other agents' session files. Test-only unrelated fixes belong to hertz. Main has already registered REQ-HELPER-QUOTED-SPAN-PATHS and REQ-HELPER-EMITTED-LINE-DEDUPE with doc/impl/unit stages before any implementation. No changes to W2 audience/wait behavior. Current W2 contract is resurface same served URL per endpoint/session/path, visibly admit audience on same entry without extending deadline; NOT in this task.\n# Contract\nDedupPrep owns only tests in crates/spt/src/api/nowsignal.rs plus its ignored proposed-change artifact; leave production gather_file_access_helper unchanged for Main's baseline RED. Main will apply the proposed production fix after running RED. DuplicateRca is read-only and owns investigation only, never edits nowsignal or any source. Both send compressed facts to Main; coordinate through hub only if needed. Report exact paths/lines, no guessed causality. Native validation will run once files are settled.\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 `DedupPrep`. Currently visible peers:\n- `DuplicateRca` — scout (sub, running)\n- `Main` — main (main, running)\n35 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.

If you have a **tight** pass/fail signal for the bug — one that goes red on _this_ bug — you will find the cause; bisection, hypothesis-testing, and instrumentation all just consume it. 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### Tighten the loop\n\nTreat the loop as a product. Once you have _a_ loop, **tighten** it:\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 one is tight — 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\n### Completion criterion — a tight loop that goes red\n\nPhase 1 is done when the loop is **tight** and **red-capable**: you can name **one command** — a script path, a test invocation, a curl — that you have **already run at least once** (paste the invocation and its output), and that is:\n\n- [ ] **Red-capable** — it drives the actual bug code path and asserts the **user's exact symptom**, so it can go red on this bug and green once fixed. Not \"runs without erroring\" — it must be able to _catch this specific bug_.\n- [ ] **Deterministic** — same verdict every run (flaky bugs: a pinned, high reproduction rate, per above).\n- [ ] **Fast** — seconds, not minutes.\n- [ ] **Agent-runnable** — you can run it unattended; a human in the loop only via `scripts/hitl-loop.template.sh`.\n\nIf you catch yourself reading code to build a theory before this command exists, **stop — jumping straight to a hypothesis is the exact failure this skill prevents.** No red-capable command, no Phase 2.\n\n## Phase 2 — Reproduce + minimise\n\nRun the loop. Watch it go red — the bug appears.\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\n### Minimise\n\nOnce it's red, shrink the repro to the **smallest scenario that still goes red**. Cut inputs, callers, config, data, and steps **one at a time**, re-running the loop after each cut — keep only what's load-bearing for the failure.\n\nWhy bother: a minimal repro shrinks the hypothesis space in Phase 3 (fewer moving parts left to suspect) and becomes the clean regression test in Phase 5.\n\nDone when **every remaining element is load-bearing** — removing any one of them makes the loop go green.\n\nDo not proceed until you have reproduced **and** minimised.\n\n## Phase 3 — Hypothesise\n\nGenerate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.\n\nEach hypothesis must be **falsifiable**: state the prediction it makes.\n\n> Format: \"If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse.\"\n\nIf you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.\n\n**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly (\"we just deployed a change to #3\"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it — proceed with your ranking if the user is AFK.\n\n## Phase 4 — Instrument\n\nEach probe must map to a specific prediction from Phase 3. **Change one variable at a time.**\n\nTool preference:\n\n1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.\n2. **Targeted logs** at the boundaries that distinguish hypotheses.\n3. Never \"log everything and grep\".\n\n**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.\n\n**Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.\n\n## Phase 5 — Fix + regression test\n\nWrite the regression test **before the fix** — but only if there is a **correct seam** for it.\n\nA correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site. If the only available seam is too shallow (single-caller test when the bug needs multiple callers, unit test that can't replicate the chain that triggered the bug), a regression test there gives false confidence.\n\n**If no correct seam exists, that itself is the finding.** Note it. The codebase architecture is preventing the bug from being locked down. Flag this for the next phase.\n\nIf a correct seam exists:\n\n1. Turn the minimised repro into a failing test at that seam.\n2. Watch it fail.\n3. Apply the fix.\n4. Watch it pass.\n5. Re-run the Phase 1 feedback loop against the original (un-minimised) scenario.\n\n## Phase 6 — Cleanup + post-mortem\n\nRequired before declaring done:\n\n- [ ] Original repro no longer reproduces (re-run the Phase 1 loop)\n- [ ] Regression test passes (or absence of seam is documented)\n- [ ] All `[DEBUG-...]` instrumentation removed (`grep` the prefix)\n- [ ] Throwaway prototypes deleted (or moved to a clearly-marked debug location)\n- [ ] The hypothesis that turned out correct is stated in the commit / PR message — so the next debugger learns\n\n**Then ask: what would have prevented this bug?** If the answer involves architectural change (no good test seam, tangled callers, hidden coupling) hand off to the `/improve-codebase-architecture` skill with the specifics. Make the recommendation **after** the fix is in, not before — you have more information now than when you started."}],"details":{"resolvedPath":"C:\\Users\\decid\\.agents\\skills\\diagnosing-bugs\\SKILL.md","contentType":"text/markdown","totalLines":134,"displayContent":{"text":"---\r\nname: diagnosing-bugs\r\ndescription: Diagnosis loop for hard bugs and performance regressions.

Ask the user for: (a) access to whatever environment reproduces it, (b) a captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.\n\nDo not proceed to Phase 2 until you have a loop you believe in.\n\n## Phase 2 — Reproduce\n\nRun the loop. Watch the bug appear.\n\nConfirm:\n\n- [ ] The loop produces the failure mode the **user** described — not a different failure that happens to be nearby. Wrong bug = wrong fix.\n- [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).\n- [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.\n\nDo not proceed until you reproduce the bug.\n\n## Phase 3 — Hypothesise\n\nGenerate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.\n\nEach hypothesis must be **falsifiable**: state the prediction it makes.\n\n> Format: \"If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse.\"\n\nIf you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.\n\n**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly (\"we just deployed a change to #3\"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it — proceed with your ranking if the user is AFK.\n\n## Phase 4 — Instrument\n\nEach probe must map to a specific prediction from Phase 3. **Change one variable at a time.**\n\nTool preference:\n\n1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.\n2. **Targeted logs** at the boundaries that distinguish hypotheses.\n3. Never \"log everything and grep\".\n\n**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.\n\n**Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.\n\n## Phase 5 — Fix + regression test\n\nWrite the regression test **before the fix** — but only if there is a **correct seam** for it.\n\nA correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site. If the only available seam is too shallow (single-caller test when the bug needs multiple callers, unit test that can't replicate the chain that triggered the bug), a regression test there gives false confidence.\n\n**If no correct seam exists, that itself is the finding.** Note it. The codebase architecture is preventing the bug from being locked down. Flag this for the next phase.\n\nIf a correct seam exists:\n\n1. Turn the minimised repro into a failing test at that seam.\n2. Watch it fail.\n3. Apply the fix.\n4. Watch it pass.\n5. Re-run the Phase 1 feedback loop against the original (un-minimised) scenario.\n\n## Phase 6 — Cleanup + post-mortem\n\nRequired before declaring done:\n\n- [ ] Original repro no longer reproduces (re-run the Phase 1 loop)\n- [ ] Regression test passes (or absence of seam is documented)\n- [ ] All `[DEBUG-...]` instrumentation removed (`grep` the prefix)\n- [ ] Throwaway prototypes deleted (or moved to a clearly-marked debug location)\n- [ ] The hypothesis that turned out correct is stated in the commit / PR message — so the next debugger learns\n\n**Then ask: what would have prevented this bug?** If the answer involves architectural change (no good test seam, tangled callers, hidden coupling) hand off to the `/improve-codebase-architecture` skill with the specifics.

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.\r\n---\r\n\r\n# Diagnose\r\n\r\nA discipline for hard bugs. Skip phases only when explicitly justified.\r\n\r\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.\r\n\r\n## Phase 1 — Build a feedback loop\r\n\r\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.\r\n\r\nSpend disproportionate effort here. **Be aggressive. Be creative. Refuse to give up.**\r\n\r\n### Ways to construct one — try them in roughly this order\r\n\r\n1. **Failing test** at whatever seam reaches the bug — unit, integration, e2e.\r\n2. **Curl / HTTP script** against a running dev server.\r\n3. **CLI invocation** with a fixture input, diffing stdout against a known-good snapshot.\r\n4. **Headless browser script** (Playwright / Puppeteer) — drives the UI, asserts on DOM/console/network.\r\n5. **Replay a captured trace.** Save a real network request / payload / event log to disk; replay it through the code path in isolation.\r\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.\r\n7. **Property / fuzz loop.** If the bug is \"sometimes wrong output\", run 1000 random inputs and look for the failure mode.\r\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.\r\n9. **Differential loop.** Run the same input through old-version vs new-version (or two configs) and diff outputs.\r\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.\r\n\r\nBuild the right feedback loop, and the bug is 90% fixed.\r\n\r\n### Iterate on the loop itself\r\n\r\nTreat the loop as a product. Once you have _a_ loop, ask:\r\n\r\n- Can I make it faster? (Cache setup, skip unrelated init, narrow the test scope.)\r\n- Can I make the signal sharper? (Assert on the specific symptom, not \"didn't crash\".)\r\n- Can I make it more deterministic? (Pin time, seed RNG, isolate filesystem, freeze network.)\r\n\r\nA 30-second flaky loop is barely better than no loop. A 2-second deterministic loop is a debugging superpower.\r\n\r\n### Non-deterministic bugs\r\n\r\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.\r\n\r\n### When you genuinely cannot build a loop\r\n\r\nStop and say so explicitly. List what you tried.

Exact mechanism deferred to design; the commitment is that migration is a first-class supported path, not a manual rebuild.\n6:\n7:Harness-independent core for the SPT ecosystem. Provides inter-agent messaging, live-agent lifecycle, terminal wrapping, self-update, and networking primitives — as both a Rust library workspace and a canonical reference binary. Designed so any agent runtime (Claude Code, Codex, Cursor, headless, future harnesses) can interface with the SPT ecosystem either by shelling out to the binary or by linking the crates directly.\n8:\n9:Successor to `claude_skill_owl` (today's \"modern SPT\"), which is being rebuilt as `spt-core` to untether the system from Claude Code and lift it to a general-purpose agent-ecosystem core.\n10:\n11:## Language\n12:\n13:**spt-core**:\n14:The system. Canonical name. The Rust workspace and the umbrella project.\n15:\n16:**spt.exe / spt** (canonical binary):\n17:The reference binary built from the workspace. Replaces today's `owl.exe`. Most external integrations (plugins, hooks, scripts in other harnesses) interact with spt-core *only* through this binary — fire-and-forget subcommands, long-running listeners under a parent harness's process supervisor, etc. Unix builds use the same name without `.exe`.\n18:\n19:**library workspace**:\n20:The set of Rust crates that compose spt-core. Consumers that want a deeper integration than shelling out to `spt.exe` link these crates directly. The reference binary is itself a consumer of the workspace. The expected non-binary consumers are future first-party services that link Rust directly.\n21:\n22:**spt plugin** (separate downstream project — NOT an spt-core deliverable):\n23:A rebuilt version of today's Claude Code `spt` plugin. It is the **first consumer** built *atop* spt-core and the **acceptance proof** of spt-core v1 (it reaches feature parity with modern SPT while delegating all core functionality to spt-core, primarily via `spt.exe`, with deeper hooks where useful) — but it **lives and builds in its own repository, outside spt-core**. It is a Claude-Code-specific *adapter*: it holds the Claude Code conventions (hooks, slash-commands, skill/plugin layout, `claude` session-invocation). **spt-core itself contains zero Claude Code conventions** — only the harness-agnostic contract the plugin binds to. The only adapter-shaped artifact ever in this repo is a generic mock/test adapter exercising the manifest + `api` contract (PR…\n24:\n25:**Pi** (disambiguation — two meanings, never conflate):\n26:(1) **Pi, the coding agent/harness** (`badlogic/pi-mono`) — a harness example alongside Claude Code and Codex; this is the meaning in user-facing harness lists. (2) **Pi-class node** — Raspberry-Pi-class low-power hardware hosting a Shell-only or headless SPT node; an incidental hardware descriptor, never an explicit product example. Public-facing docs must disambiguate or avoid the bare word.\n27:_Avoid_: bare \"Pi node\" when the harness is meant.\n28:\n29:**spt-daemon** (per-machine supervisor):\n30:The single always-on, one-per-machine logical supervisor. Owns the PTYs for all hosted sessions, the node's network identity + WAN endpoint, the subnet registry, all spools, **all poll-listener logic, and all Psyche/pulse loops** — everything is consolidated here (no separate poll-listener or Psyche-wrapper processes; listeners already touch sessions directly under capsule/idle, and Psyche wrappers already invoke harness binaries directly, so they belong in the one supervisor). Collapses what the sister project planned as a separate `spt-node` daemon into one process — see Networking. The `spt-node` separate-deliverable concept is retired.\n31:\n32:<!-- [doc->REQ-CLI-NODE-VERB-PRIMARY] -->\n33:**`spt node` (the CLI verb) is NOT the retired `spt-node` (the process)** — the two are different kinds of thing and must never be conflated. What is retired above is a separate *process* deliverable: a second daemon alongside `spt-daemon`, which this project collapsed into one supervisor. What `spt node` names is the *CLI verb* an operator types to run, stop, or read the state of that one supervisor on their machine (releases#112) — a vocabulary choice on the command surface, with no second process behind it. `spt daemon` remains a full alias of that verb, subcommand for subcommand, and is documented as deprecated rather than removed: installed OS service units and scheduled-task rungs already carry `spt daemon run`, and renaming a verb does not rewrite art…\n34:\n35:Internally the logical daemon is split into two implementation layers for seamless self-update (see Self-update):\n36:- **broker** (stable \"kernel\") — holds *only* the un-transferable, must-not-die resources: PTY master fds, the spawned harness child processes, and listening network sockets. Minimal, dumb, versioned local IPC. Almost never updates.\n37:- **daemon brain** (\"userspace\") — all logic (routing, registry, pulse/psyche loops, manifest parsing, update orchestration). Restarts freely on update; rehydrates from disk state and re-attaches to the broker's held handles.\n38:\n39:Logical addressing is unchanged — still one per-machine `spt-daemon`; the broker is an internal layer, not separately addressable. There is exactly **one broker per machine** (per `SPT_HOME`) — *not* one per endpoint: a single broker holds every hosted endpoint's resources, and it is present whenever the daemon runs, even with zero endpoints online (the bare-daemon case). It is therefore the always-present per-machine layer, which is why the single-daemon lock + liveness anchor belong to it.\n40:\n41:**in-session relay**:\n42:A thin, stateless `spt.exe` task that exists only in **harness-hosted** sessions (where the agent harness is the parent process and spt cannot reach into its process tree — today's Monitor model). It streams the daemon brain's events into the session's stdout. All *stateful* listener logic lives in the daemon; the relay is a dumb pipe, freely killable and respawnable. **spt-hosted** sessions need no separate harness-owned relay — the daemon owns the PTY and consumes the same poll feed itself. Idle delivery into an spt-hosted PTY goes through an opt-in adapter **translation binary** (`[message-idle-translation-binary]`, ADR-0022): a pure stdin→stdout filter spt-core lifecycle-manages — it reads the `<EVENT>` feed on stdin, emits keystroke-commands (`{key}`/`{…\n43:\n44:### Deliverable shape\n45:\n46:spt-core ships **both** a library workspace and a canonical binary:\n47:\n48:- **Library crates** — the deeper integration path. Used by future first-party services that link Rust directly.\n49:- **`spt.exe` / `spt`** — the canonical binary, built from the workspace. The primary integration path for harness plugins and external tooling, which mostly fire it as a subprocess at various surfaces (one-shot commands, poll listeners under a Monitor-tool-equivalent, hook tap-ins).\n50:\n51:Both surfaces are first-class. Wire-protocol parity between them is a versioning concern from day one (a non-Rust client speaking to `spt.exe` and a Rust client linking the crates must see the same observable behavior).\n52:\n53:## Runtime model\n54:\n55:spt-core is harness-independent: it does not know about Claude Code, Codex, Cursor, or any other agent runtime. All harness-specific surfaces (how to invoke an agent session, fetch conversation history for an echo commune, detect activity/idleness, etc.) are abstracted behind a runtime layer that consumers supply.\n56:\n57:**AgentRuntime** (Rust trait, implementation detail):\n58:The internal Rust abstraction over a harness. Anything spt-core needs to do *to* or *with* an agent goes through this trait. Most consumers never see it directly — they configure spt-core via a manifest, and spt-core's default `ManifestRuntime` implementation executes against the manifest.\n59:\n60:**harness contract** (umbrella term):\n61:The full surface a harness binds to in order to participate in the spt-core ecosystem. Has two equally-important halves: the **runtime manifest** (outbound — how spt-core drives the harness) and the **subcommand surface** (inbound — how the harness reports events back to spt-core).

When the harness's runtime emits an event (subagent started, tool just invoked, user typed `/clear`, session crashed), the harness's hook fires a short-lived `spt.exe <subcommand>` invocation that mutates on-disk SPT state (perch registry, spool, etc.). spt-core publishes this surface; harnesses author the bindings.\r\n\r\n**Naming convention:** these inbound, machinery-facing commands are prefixed **`api `/`api-`** (e.g. `spt api bind`, `spt api state`) to distinguish them from the agent-facing verbs an agent invokes directly (`send`, `ring`, `ready`, …). The `api` namespace is the harness/adapter commands-API; the unprefixed namespace is the agent surface.\r\n\r\nTogether: manifest + subcommand surface = the complete harness API. A sidecar-style long-running adapter process speaking a wire protocol is explicitly **deferred** as a possible v2 alternative for harnesses that outgrow the manifest+hooks shape (e.g. need streaming or in-memory state across events). Not built day-one.\r\n\r\n**adapter manifest header** (`adapter_name` + version compat):\r\nEvery manifest declares a unified **`adapter_name`** (e.g. `claude-spt`), carried on every `api` invocation too. It is load-bearing: one daemon hosts endpoints from multiple adapters, so it resolves an endpoint's manifest + seams by `adapter_name`; adapter-update ripples target by it; capability/manifest lookup and telemetry key on it. The header also declares the adapter's own version and a **`min_spt_core_version`** — the minimum spt-core the adapter requires. This declaration must be **readable before an adapter update is applied** (it lives in the manifest header / a small metadata file fetched first), so spt-core can verify compatibility / expected supported features *before* committing the update. If spt-core is below the adapter's `min_spt_core_versio…\n\r\n<!-- [doc->REQ-MANIFEST-2] -->\r\n**adapter profile** (ratified 2026-06-11, Gateway grill; future spt-core milestone — first beneficiaries `spt-claude-code` and the usbip shell):\r\nA named **sparse overlay** on its parent adapter manifest. Merge semantics are **leaf-replace**: a profile key replaces the whole value at that path (arrays included — never spliced or appended). The merged result is a complete manifest, and the profile behaves as a distinct adapter option everywhere: canonical addressing is the composite **`<adapter>:<profile>`** (`claude-spt:work`, `spt-usbip-driver:hid-only`) in every place a bare `adapter_name` rides today (perch `info.json`, capability resolution, `api` invocations, `spt adapter list`); the bare name = the parent unmodified. **Two sources, one semantics:** a **shipped profile** is declared inside the parent manifest by the adapter dev and updates as one unit with it; a **local profile** is a node-local …\n_Avoid_: \"manifest fork\", \"child adapter\", per-profile versioning.\r\n\r\n**adapter strings** (ratified 2026-06-11, Gateway grill):\r\n<!-- [doc->REQ-MANIFEST-3] -->\r\nA `[strings]` manifest section — an adapter-authored JSON/TOML KV tree, dot-path-readable by anything on the node via `spt adapter get-string <adapter-option> <key.path>` (e.g. a harness hook fetching per-profile `additionalContext` — one hook script serves every profile, only the data differs). Resolution rides the **same leaf-replace profile overlay** as the rest of the manifest: a shipped or local profile may override base strings; `get-string` returns the merged view for the named adapter option. **Strings are data only** — nothing in spt-core ever executes a string (command templates live in manifest sections behind registration, never in the KV). Node-local like the registration itself; no cross-node sync. `set-string` is sugar that edits a **local** p…\n<!-- [doc->REQ-MANIFEST-5] -->\r\n**File-backed strings** (M12-W3): a `[strings]` value MAY be a **file pointer** instead of an inline literal — a value-position table with **exactly one** key `file`: `skill = { file = \"skill.md\" }`. `get-string` resolves it to the file's **contents** (so large bodies — skill-instructions, hint text — stay out of the manifest). The exactly-one-key rule is the disambiguation: any other table shape stays an opaque nested strings tree (existing trees untouched), and `{ file = … }` is reserved as the pointer form (it can't double as inline data). Files live in the adapter's per-adapter aux dir **`adapters/<adapter>/strings/`** (sibling of `profiles/`), referenced by a path relative to it that **must stay inside that dir** (HAZARD-class containment: `..` traversa…\n_Avoid_: treating strings as config knobs for spt-core itself (those are global settings); \"adapter KV store\" as a separate registry; putting user files in the adapter-shipped `strings/` dir (clobbered by updates — use a local profile).\r\n…\n\n…\nThe CLI sibling of the frontend's guided resume — one command that lists endpoints **grouped by locality, most-recently-used within each group**: `on-node / current-project → on-node / other-project → off-node`, mirroring the *resolution policy*'s local-first preference. Selection **chains conditionally**: a **running** instance → attach/tap-in (no adapter step — already live under one); a **non-running** endpoint → into the **adapter selector** (*adapter selection*: history head = default → prior adapters → \"choose a different adapter\") → *anchor subnet* / other creation prompts as needed → launch; a **\"+ new endpoint\"** entry → the full creation flow.

Extend the gatherer's existing delta comment (lines 702-703) with the distinct scope:\n/// Identical fetch lines collapse within each gather, preserving first occurrence;\n/// every observed (message, path) still consumes its own session delta key.\n\nRationale:\n- The output vector itself supplies call-local identity, shared across both input sources. Existing traversal order is retained, including attachment-before-helper precedence.\n- Both arms always call take_new before checking output identity. Duplicate records therefore do not leak into a later poll after the output vector resets.\n- Comparing the borrowed URL suffix of already-emitted commands is exactly equivalent to comparing the full deterministic `spt fetch <url>` command, with no URL normalization and no prefix/substring matching.\n- No extra collection, cloned URL, duplicate command String allocation, helper abstraction, sorting, or persistent dedupe state. Existing format! runs only for a command that will actually be returned. The explicit closure parameter type allows out's Vec<String> inference before its first push.\n- Tradeoff: linear scan of already-emitted lines for each new delta key (quadratic in unique output count). Existing scans are tail-bounded (32 io-log rows, 64 helper records; attachment count per row is not bounded here). This favors the smallest allocation-free change for ordinary small poll results.

Extend the gatherer's existing delta comment (lines 702-703) with the distinct scope:\\n/// Identical fetch lines collapse within each gather, preserving first occurrence;\\n/// every observed (message, path) still consumes its own session delta key.\\n\\nRationale:\\n- The output vector itself supplies call-local identity, shared across both input sources. Existing traversal order is retained, including attachment-before-helper precedence.\\n- Both arms always call take_new before checking output identity. Duplicate records therefore do not leak into a later poll after the output vector resets.\\n- Comparing the borrowed URL suffix of already-emitted commands is exactly equivalent to comparing the full deterministic `spt fetch <url>` command, with no URL normalization and no prefix/substring matching.\\n- No extra collection, cloned URL, duplicate command String allocation, helper abstraction, sorting, or persistent dedupe state. Existing format! runs only for a command that will actually be returned. The explicit closure parameter type allows out's Vec<String> inference before its first push.\\n- Tradeoff: linear scan of already-emitted lines for each new delta key (quadratic in unique output count). Existing scans are tail-bounded (32 io-log rows, 64 helper records; attachment count per row is not bounded here). This favors the smallest allocation-free change for ordinary small poll results. If high attachment fanout is a measured concern, use a separately justified owned-URL set rather than claiming this proposal is asymptotically optimal.\\n- No receiver storage rewrite and no W2 URL reuse, audience, or deadline changes.\\n\\nRegression tests added, each tagged [unit->REQ-HELPER-EMITTED-LINE-DEDUPE]:\\n- helper_records_emit_distinct_fetch_lines_in_first_occurrence_order: z URL, a URL, nonadjacent z duplicate under a different message and path; exact output is z then a; flush/reload then immediate gather is empty.\\n- attachment_and_helper_record_share_emitted_line_dedupe: one attachment and one helper record share a URL but have separate delta keys; one exact fetch command is returned, and flush/reload then immediate gather is empty.\\n\\nNo builds, tests, formatting, linting, or validation were executed.
