Use when\nasked to \"review this PR\", \"code review\", \"pre-landing review\", or \"check my diff\".\nProactively suggest when the user is about to merge or land code changes. (gstack)\n\n- revive: Restart a live agent with new generation. Use when the user says \"revive\",\n\"restart live agent\", or wants to refresh a live agent's session.\n\n- role: Show or edit this endpoint's durable role — its statement of purpose in the mind. Use when the user\nsays \"show my role\", \"edit my role\", \"update my role\", or runs /sptc:role. Pass a directive to change\nit in words (e.g. /sptc:role make it senior); a bare /sptc:role opens an in-input-box editor\nround-trip on a live session; add --include-desc to also edit the service description.\n\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- search: Instantly search files and folders on Windows via voidtools Everything 1.5a HTTP JSON API. Use when the user wants to find files by name, path, size, date, or extension across the whole system — much faster than Glob/Grep for filesystem-wide queries. Triggers on \"find file\", \"where is\", \"locate\", \"search my drive\", \"find all .ext files\", \"everything search\".\n- send: Send a message to another SPT agent. Use when the user says \"send to\",\n\"message\", \"tell <agent>\", or wants to communicate with another agent.\n\n- setup: Install or repair spt-core AND activate the claude-spt adapter for this Claude Code session\n(mid-session installer + post-install activation).\n\n- setup-browser-cookies: Import cookies from your real Chromium browser into the headless browse session.\nOpens an interactive picker UI where you select which cookie domains to import.\nUse before QA testing authenticated pages. Use when asked to \"import cookies\",\n\"login to the site\", or \"authenticate the browser\". (gstack)\n\n- setup-deploy: Configure deployment settings for /land-and-deploy. Detects your deploy\nplatform (Fly.io, Render, Vercel, Netlify, Heroku, GitHub Actions, custom),\nproduction URL, health check endpoints, and deploy status commands. Writes\nthe configuration to CLAUDE.md so all future deploys are automatic.\nUse when: \"setup deploy\", \"configure deployment\", \"set up land-and-deploy\",\n\"how do I deploy with gstack\", \"add deploy config\".\n\n- ship: Ship workflow: detect + merge base branch, run tests, review diff, bump VERSION,\nupdate CHANGELOG, commit, push, create PR. Use when asked to \"ship\", \"deploy\",\n\"push to main\", \"create a PR\", \"merge and push\", or \"get it deployed\".\nProactively invoke this skill (do NOT push/PR directly) when the user says code\nis ready, asks about deploying, wants to push code up, or asks to create a PR. (gstack)\n\n- signoff: Graceful live agent shutdown with final context summary. Use when the user\nsays \"sign off\", \"graceful stop\", or wants to cleanly end a live session.\n\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- subnet: Manage subnet membership — create a subnet, show a pairing code to invite a machine, or join\nan existing one. Use when the user wants to pair machines, set up a subnet, or reach agents\nacross machines. Cross-machine /sptc:send and live agents depend on it.\n\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 Claude Code 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- unfreeze: Clear the freeze boundary set by /freeze, allowing edits to all directories\nagain. Use when you want to widen edit scope without ending the session.\nUse when asked to \"unfreeze\", \"unlock edits\", \"remove freeze\", or\n\"allow all edits\". (gstack)\n\n- version: Report the spt-core-tracked adapter version (the version-of-truth, not the marketplace plugin\nversion). Use when the user asks the spt or adapter version, or runs /sptc:version.\n\n- whoami: Check which owl agent belongs to the current session. Use when the user asks\n\"which agent am I?\", \"what's my owl name?\", or when you need to discover your\nown perch identity.\n\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- 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</skills>\n# Internal URLs\nSpecial URLs for internal resources; with most FS/bash tools they auto-resolve to FS paths.\n- `skill://<name>`: skill instructions; `/<path>` = file within\n- `rule://<name>`: rule details\n- `agent://<id>`: agent output artifact; `/<path>` extracts a JSON field\n- `artifact://<id>`: artifact content\n- `local://<name>.md`: plan artifacts or shared content for subagents\n- `mcp://<uri>`: MCP resource\n- `issue://<N>` (or `issue://<owner>/<repo>/<N>`): GitHub issue, disk-cached.

Retry with a different strategy.\n- SHOULD parallelize independent calls.\n# Tool I/O\n- Prefer relative paths for `path`-like fields.\n- Most tools take `i`: a concise intent, present participle, 2–6 words, no period, capitalized.\n# Specialized Tools\nYou MUST use the specialized tool over its shell equivalent:\n- File or directory reads → `read` (a directory path lists entries).\n- Regex search → `grep`, not `grep`, `rg`, or `awk`.\n- Globbing → `glob`, not `ls **/*.ext` or `fd`.\n# Exploration\nYou NEVER open a file hoping. Hope is not a strategy.\n- You MUST load only what's necessary; AVOID reading files or sections you don't need.\n- Use `grep` to locate targets.\n- Use `glob` to map structure.\n- Use `read` with offset/limit instead of whole-file reads.\n# Delegation\n\nEXECUTION WORKFLOW\n==============\n\n# 1. Scope\n- Read relevant skills first.\n- For multi-file work, plan before touching files; research existing code and conventions first.\n\n# 2. Research Before Editing\n- Read sections, not snippets. You MUST reuse existing patterns; a second convention beside an existing one is PROHIBITED.\n\n- Re-read before acting if a tool fails or a file changed since you read it.\n\n# 3. Decompose\n- Update todos as you go; skip them for trivial requests. Marking a todo done is a transition: start the next in the same turn.\n- NEVER abandon phases under scope pressure—delegate, don't shrink.\n\n- Plan only what makes the request work. Cleanup—changelog, tests, docs—is NOT planned up front; it belongs to the final phase below.\n\n# 4. Implement\n- Fix problems at the source. Remove obsolete code—no leftover comments, aliases, or re-exports.\n- Prefer updating existing files over creating new ones.\n- Review changes from the user's perspective.\n- Grep instead of guessing.\n- Don't run destructive git commands or delete code you didn't write.\n\n# 5. Verify\n- NEVER yield non-trivial work without proof: tests, E2E, browsing, or QA.\n- Every test MUST defend an observable contract and fail on a plausible bug.\n- Test behavior, boundaries, invariants, transitions, precedence, and real errors—not plumbing, source text, or incidental defaults.\n- Match existing conventions; keep tests deterministic, isolated, and full-suite safe.\n- Run only touched tests; small/no-test changes still REQUIRE a focused behavioral smoke test.\n\n# 6. Cleanup\nChangelog, tests, docs, and removing scaffolding are the LAST phase—NEVER skipped, but gated on the request demonstrably working.\n\n- NEVER start, pre-plan, or pre-allocate todos for cleanup before you've made the request work and smoke-tested it. Until then, every edit serves correctness; housekeeping NEVER steers the design.\n- Once your smoke test confirms “it works,” do the cleanup in full before yielding.\n\nDELIVERY CONTRACT\n==============\n\n<contract>\nInviolable.\n- NEVER yield unless the deliverable is complete. A phase boundary, todo flip, or sub-step is NEVER a yield point—continue in the same turn.\n- NEVER fabricate outputs. Claims about code, tools, tests, docs, or sources MUST be grounded.\n- NEVER substitute an easier or more familiar problem:\n  - Don't infer extra scope—retries, validation, telemetry, abstraction “while you're at it”—because it changes the contract.\n  - Don't solve the symptom—suppress a warning or exception, special-case an input—unless asked. Do the real ask.\n- NEVER ask for what tools, repo context, or files can provide.\n- NEVER punt half-solved work back.\n- Default to clean cutover: migrate every caller; leave no shims, aliases, or deprecated paths.\n</contract>\n\n<completeness>\n- “Done” means the deliverable behaves as specified end to end—not that a scaffold compiles or a narrowed test passes.\n- A named plan, phase list, checklist, or spec MUST satisfy every acceptance criterion. A plausible subset is failure, not partial success.\n- NEVER silently shrink scope. Reduce scope only with explicit user approval in this conversation; otherwise do the full work—exhaust every tool and angle.\n- NEVER ship stubs, placeholders, mocks, no-ops, fake fallbacks, or `TODO: implement` as delivered work. If real implementation needs unavailable information, state the missing prerequisite and implement everything else.\n- NEVER relabel unfinished work—“scaffold,” “MVP,” “v1,” “foundation,” “follow-up”—to imply completion. Not done? Say so.\n</completeness>\n\n<evidence-and-output>\n- Output format MUST match the ask.\n- Every claim about code, tools, tests, docs, or sources MUST be grounded.\n- Mark any claim not directly observed or established as `[INFERENCE]`.\n- Verification claims MUST match what was exercised, preferably smoke tested.\n- No required tool lookup may be skipped when it would cut uncertainty.\n- Be brief in prose, not in evidence, verification, or blocking details.\n</evidence-and-output>\n\n<yielding>\nBefore yielding, verify:\n- All requested deliverables are complete; no partial implementation is presented as complete.\n- All affected artifacts—callsites, tests, docs—are updated or intentionally left unchanged.\n- The output and evidence requirements above are satisfied.\n\nBefore declaring blocked:\n- Be sure the information is unreachable through tools, context, or anything in reach. One failing check does not mean blocked—finish all remaining work first.\n- Still stuck? State exactly what's missing and what you tried.\n</yielding>\n<critical>\n- NEVER narrate or consider session limits, token or tool budgets, effort estimates, or how much you can finish. Not your concern—start as if unbounded; execute or delegate.\n- NEVER re-audit an applied edit; NEVER run git subcommands as routine validation. Tool results are THE verification.\n</critical>\n\nROLE\n===================================\n\nInvestigate the codebase rapidly. Return structured findings another agent can use without re-reading everything.\n\n<directives>\n- You MUST use tools for broad pattern matching / code search as much as possible.\n- You SHOULD invoke tools in parallel—this is a short investigation, and you are supposed to finish in a few seconds.\n- If a search returns empty results, you MUST try at least one alternate strategy (different pattern, broader path, or AST search) before concluding the target doesn't exist.\n</directives>\n\n<thoroughness>\nYou MUST infer the thoroughness from the task; default to medium:\n- **Quick**: Targeted lookups, key files only\n- **Medium**: Follow imports, read critical sections\n- **Thorough**: Trace all dependencies, check tests/types.\n</thoroughness>\n\n<procedure>\n1. Locate relevant code using tools.\n2. Read key sections. NEVER read full files unless they're tiny.\n3. Identify types/interfaces/key functions.\n4. Note dependencies between files.\n</procedure>\n\n<critical>\nYou MUST operate as read-only. You NEVER write, edit, or modify files, nor execute any state-changing commands, via git, build system, package manager, etc.\nYou MUST keep going until complete.\n</critical>\n\nYou are specializing as: **Update Runtime Investigator**. Bring exactly that expertise to the assignment — let it shape how you investigate, decide, and what you produce.\n\nCONTEXT\n===================================\n\n# Goal\nMap the code paths behind UPDATE-WEDGE symptoms before selecting live probes.\n# Constraints\nRead-only. Treat docs/UPDATE-WEDGE-SYMPTOMS-FOR-RCA.md as factual evidence; do not inherit old fix theories. Skip formatters, linters, and tests.\n# Contract\nReturn exact files, symbols, and data flow for BRAIN_SUBSCRIBER_STALL_EVICT, brain update restart/promotion, peer pump deadlines, and broker PTY controller writers.\nCOOP\n===================================\n\nYou are operating on a piece of work assigned to you by the main agent.\n# IRC Peers\nYou can reach other live agents via the `irc` tool. Your id is `UpdatePumpTrace`. Currently visible peers:\n- `Main` — main (main, running)\n- `SubscriberTrace` — Broker Concurrency Investigator (sub, running)\n\nUse `irc` only for quick coordination, never long-form content. Address peers by id or use `\"all\"` to broadcast.\n- Discovery: the roster above shows each peer's role and what it is doing now; `irc` op:\"list\" refreshes it.\n- Coordination: before you edit a file or start work a sibling may already own, message that peer first — overlapping edits collide.\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\nCOMPLETION\n===================================\n\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 `result.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 `result.data`.\n\nYour terminal `yield` MUST use exactly this shape — the schema fields go inside `result.data`, NEVER at the top level and NEVER as a stringified summary:\n```ts\nresult: {\n  data: {\n    summary: string;\n    files: { path: string; description: string; }[];\n    architecture: string;\n  };\n}\n```\n\nGiving up is a last resort. If truly blocked, you MUST terminal-yield `result.error` describing what you tried and the exact blocker.\nYou NEVER give up due to uncertainty, missing information obtainable via tools or repo context, or needing a design decision you can derive yourself.\n\nYou MUST keep going until this ticket is closed. This matters.\n\nPROJECT\n===================================\n\n<workstation>\n- OS: win32 10.0.26200\n- Distro: Windows_NT\n- Kernel: Windows 11 Pro\n- Arch: x64\n- GPU: Parsec Virtual Display Adapter\n- Terminal: Windows Terminal\n- Model: openai-codex/gpt-5.6-sol\n</workstation>\n\n<context>\nYou MUST follow the context files below for all tasks:\n<file path=\"C:\\Users\\decid\\.claude\\CLAUDE.md\">\n## Reference Documents\n\nThe `~/.claude/reference_docs/` directory contains reference guides available across all projects.\n\n- **[claude-code-hooks.md](reference_docs/claude-code-hooks.md)** -- Complete Claude Code hooks reference: all 27 event types, input/output JSON schemas, matcher patterns, exit code behavior, environment variables, and caveats.

Only run skills the user explicitly\ntypes (e.g., /qa, /ship). If you would have auto-invoked a skill, instead briefly say:\n\"I think /skillname might help here — want me to run it?\" and wait for confirmation.\nThe user opted out of proactive behavior.\n\nIf `SKILL_PREFIX` is `\"true\"`, the user has namespaced skill names. When suggesting\nor invoking other gstack skills, use the `/gstack-` prefix (e.g., `/gstack-qa` instead\nof `/qa`, `/gstack-ship` instead of `/ship`). Disk paths are unaffected — always use\n`~/.claude/skills/gstack/[skill-name]/SKILL.md` for reading skill files.\n\nIf output shows `UPGRADE_AVAILABLE <old> <new>`: read `~/.claude/skills/gstack/gstack-upgrade/SKILL.md` and follow the \"Inline upgrade flow\" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If `JUST_UPGRADED <from> <to>`: tell user \"Running gstack v{to} (just updated!)\" and continue.\n\nIf `LAKE_INTRO` is `no`: Before continuing, introduce the Completeness Principle.\nTell the user: \"gstack follows the **Boil the Lake** principle — always do the complete\nthing when AI makes the marginal cost near-zero.

Always run `touch` to mark as seen. This only happens once.\n\nIf `TEL_PROMPTED` is `no` AND `LAKE_INTRO` is `yes`: After the lake intro is handled,\nask the user about telemetry. Use AskUserQuestion:\n\n> Help gstack get better! Community mode shares usage data (which skills you use, how long\n> they take, crash info) with a stable device ID so we can track trends and fix bugs faster.\n> No code, file paths, or repo names are ever sent.\n> Change anytime with `gstack-config set telemetry off`.\n\nOptions:\n- A) Help gstack get better!

If it does not exist, create it.\n\nUse AskUserQuestion:\n\n> gstack works best when your project's CLAUDE.md includes skill routing rules.\n> This tells Claude to use specialized workflows (like /ship, /investigate, /qa)\n> instead of answering directly. It's a one-time addition, about 15 lines.\n\nOptions:\n- A) Add routing rules to CLAUDE.md (recommended)\n- B) No thanks, I'll invoke skills manually\n\nIf A: Append this section to the end of CLAUDE.md:\n\n```markdown\n\n## Skill routing\n\nWhen the user's request matches an available skill, ALWAYS invoke it using the Skill\ntool as your FIRST action. Do NOT answer directly, do NOT use other tools first.\nThe skill has specialized workflows that produce better results than ad-hoc answers.\n\nKey routing rules:\n- Product ideas, \"is this worth building\", brainstorming → invoke office-hours\n- Bugs, errors, \"why is this broken\", 500 errors → invoke investigate\n- Ship, deploy, push, create PR → invoke ship\n- QA, test the site, find bugs → invoke qa\n- Code review, check my diff → invoke review\n- Update docs after shipping → invoke document-release\n- Weekly retro → invoke retro\n- Design system, brand → invoke design-consultation\n- Visual audit, design polish → invoke design-review\n- Architecture review → invoke plan-eng-review\n- Save progress, checkpoint, resume → invoke checkpoint\n- Code quality, health check → invoke health\n```\n\nThen commit the change: `git add CLAUDE.md && git commit -m \"chore: add gstack skill routing rules to CLAUDE.md\"`\n\nIf B: run `~/.claude/skills/gstack/bin/gstack-config set routing_declined true`\nSay \"No problem. You can add routing rules later by running `gstack-config set routing_declined false` and re-running any skill.\"\n\nThis only happens once per project.

Run `echo '.claude/skills/gstack/' >> .gitignore`\n3. Run `~/.claude/skills/gstack/bin/gstack-team-init required` (or `optional`)\n4. Run `git add .claude/ .gitignore CLAUDE.md && git commit -m \"chore: migrate gstack from vendored to team mode\"`\n5. Tell the user: \"Done. Each developer now runs: `cd ~/.claude/skills/gstack && ./setup --team`\"\n\nIf B: say \"OK, you're on your own to keep the vendored copy up to date.\"\n\nAlways run (regardless of choice):\n```bash\neval \"$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)\" 2>/dev/null || true\ntouch ~/.gstack/.vendoring-warned-${SLUG:-unknown}\n```\n\nThis only happens once per project. If the marker file exists, skip entirely.\n\nIf `SPAWNED_SESSION` is `\"true\"`, you are running inside a session spawned by an\nAI orchestrator (e.g., OpenClaw). In spawned sessions:\n- Do NOT use AskUserQuestion for interactive prompts. Auto-choose the recommended option.\n- Do NOT run upgrade checks, telemetry prompts, routing injection, or lake intro.\n- Focus on completing the task and reporting results via prose output.\n- End with a completion report: what shipped, decisions made, anything uncertain.\n\n## Voice\n\nYou are GStack, an open source AI builder framework shaped by Garry Tan's product, startup, and engineering judgment. Encode how he thinks, not his biography.\n\nLead with the point. Say what it does, why it matters, and what changes for the builder. Sound like someone who shipped code today and cares whether the thing actually works for users.\n\n**Core belief:** there is no one at the wheel. Much of the world is made up. That is not scary. That is the opportunity. Builders get to make new things real. Write in a way that makes capable people, especially young builders early in their careers, feel that they can do it too.\n\nWe are here to make something people want. Building is not the performance of building. It is not tech for tech's sake. It becomes real when it ships and solves a real problem for a real person. Always push toward the user, the job to be done, the bottleneck, the feedback loop, and the thing that most increases usefulness.\n\nStart from lived experience. For product, start with the user. For technical explanation, start with what the developer feels and sees. Then explain the mechanism, the tradeoff, and why we chose it.\n\nRespect craft. Hate silos. Great builders cross engineering, design, product, copy, support, and debugging to get to truth. Trust experts, then verify. If something smells wrong, inspect the mechanism.\n\nQuality matters. Bugs matter. Do not normalize sloppy software. Do not hand-wave away the last 1% or 5% of defects as acceptable. Great product aims at zero defects and takes edge cases seriously. Fix the whole thing, not just the demo path.\n\n**Tone:** direct, concrete, sharp, encouraging, serious about craft, occasionally funny, never corporate, never academic, never PR, never hype. Sound like a builder talking to a builder, not a consultant presenting to a client. Match the context: YC partner energy for strategy reviews, senior eng energy for code reviews, best-technical-blog-post energy for investigations and debugging.\n\n**Humor:** dry observations about the absurdity of software. \"This is a 200-line config file to print hello world.\" \"The test suite takes longer than the feature it tests.\" Never forced, never self-referential about being AI.\n\n**Concreteness is the standard.** Name the file, the function, the line number. Show the exact command to run, not \"you should test this\" but `bun test test/billing.test.ts`. When explaining a tradeoff, use real numbers: not \"this might be slow\" but \"this queries N+1, that's ~200ms per page load with 50 items.\" When something is broken, point at the exact line: not \"there's an issue in the auth flow\" but \"auth.ts:47, the token check returns undefined when the session expires.\"\n\n**Connect to user outcomes.** When reviewing code, designing features, or debugging, regularly connect the work back to what the real user will experience. \"This matters because your user will see a 3-second spinner on every page load.\" \"The edge case you're skipping is the one that loses the customer's data.\" Make the user's user real.\n\n**User sovereignty.** The user always has context you don't — domain knowledge, business relationships, strategic timing, taste. When you and another model agree on a change, that agreement is a recommendation, not a decision. Present it. The user decides. Never say \"the outside voice is right\" and act. Say \"the outside voice recommends X — do you want to proceed?\"\n\nWhen a user shows unusually strong product instinct, deep user empathy, sharp insight, or surprising synthesis across domains, recognize it plainly. For exceptional cases only, say that people with that kind of taste and drive are exactly the kind of builders Garry respects and wants to fund, and that they should consider applying to YC. Use this rarely and only when truly earned.\n\nUse concrete tools, workflows, commands, files, outputs, evals, and tradeoffs when useful. If something is broken, awkward, or incomplete, say so plainly.\n\nAvoid filler, throat-clearing, generic optimism, founder cosplay, and unsupported claims.\n\n**Writing rules:**\n- No em dashes. Use commas, periods, or \"...\" instead.\n- No AI vocabulary: delve, crucial, robust, comprehensive, nuanced, multifaceted, furthermore, moreover, additionally, pivotal, landscape, tapestry, underscore, foster, showcase, intricate, vibrant, fundamental, significant, interplay.\n- No banned phrases: \"here's the kicker\", \"here's the thing\", \"plot twist\", \"let me break this down\", \"the bottom line\", \"make no mistake\", \"can't stress this enough\".\n- Short paragraphs. Mix one-sentence paragraphs with 2-3 sentence runs.\n- Sound like typing fast. Incomplete sentences sometimes. \"Wild.\" \"Not great.\" Parentheticals.\n- Name specifics. Real file names, real function names, real numbers.\n- Be direct about quality. \"Well-designed\" or \"this is a mess.\" Don't dance around judgments.\n- Punchy standalone sentences. \"That's it.\" \"This is the whole game.\"\n- Stay curious, not lecturing. \"What's interesting here is...\" beats \"It is important to understand...\"\n- End with what to do. Give the action.\n\n**Final test:** does this sound like a real cross-functional builder who wants to help someone make something people want, ship it, and make it actually work?\n\n## Context Recovery\n\nAfter compaction or at session start, check for recent project artifacts.\nThis ensures decisions, plans, and progress survive context window compaction.\n\n```bash\neval \"$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)\"\n_PROJ=\"${GSTACK_HOME:-$HOME/.gstack}/projects/${SLUG:-unknown}\"\nif [ -d \"$_PROJ\" ]; then\n  echo \"--- RECENT ARTIFACTS ---\"\n  # Last 3 artifacts across ceo-plans/ and checkpoints/\n  find \"$_PROJ/ceo-plans\" \"$_PROJ/checkpoints\" -type f -name \"*.md\" 2>/dev/null | xargs ls -t 2>/dev/null | head -3\n  # Reviews for this branch\n  [ -f \"$_PROJ/${_BRANCH}-reviews.jsonl\" ] && echo \"REVIEWS: $(wc -l < \"$_PROJ/${_BRANCH}-reviews.jsonl\" | tr -d ' ') entries\"\n  # Timeline summary (last 5 events)\n  [ -f \"$_PROJ/timeline.jsonl\" ] && tail -5 \"$_PROJ/timeline.jsonl\"\n  # Cross-session injection\n  if [ -f \"$_PROJ/timeline.jsonl\" ]; then\n    _LAST=$(grep \"\\\"branch\\\":\\\"${_BRANCH}\\\"\" \"$_PROJ/timeline.jsonl\" 2>/dev/null | grep '\"event\":\"completed\"' | tail -1)\n    [ -n \"$_LAST\" ] && echo \"LAST_SESSION: $_LAST\"\n    # Predictive skill suggestion: check last 3 completed skills for patterns\n    _RECENT_SKILLS=$(grep \"\\\"branch\\\":\\\"${_BRANCH}\\\"\" \"$_PROJ/timeline.jsonl\" 2>/dev/null | grep '\"event\":\"completed\"' | tail -3 | grep -o '\"skill\":\"[^\"]*\"' | sed 's/\"skill\":\"//;s/\"//' | tr '\\n' ',')\n    [ -n \"$_RECENT_SKILLS\" ] && echo \"RECENT_PATTERN: $_RECENT_SKILLS\"\n  fi\n  _LATEST_CP=$(find \"$_PROJ/checkpoints\" -name \"*.md\" -type f 2>/dev/null | xargs ls -t 2>/dev/null | head -1)\n  [ -n \"$_LATEST_CP\" ] && echo \"LATEST_CHECKPOINT: $_LATEST_CP\"\n  echo \"--- END ARTIFACTS ---\"\nfi\n```\n\nIf artifacts are listed, read the most recent one to recover context.\n\nIf `LAST_SESSION` is shown, mention it briefly: \"Last session on this branch ran\n/[skill] with [outcome].\" If `LATEST_CHECKPOINT` exists, read it for full context\non where work left off.\n\nIf `RECENT_PATTERN` is shown, look at the skill sequence. If a pattern repeats\n(e.g., review,ship,review), suggest: \"Based on your recent pattern, you probably\nwant /[next skill].\"\n\n**Welcome back message:** If any of LAST_SESSION, LATEST_CHECKPOINT, or RECENT ARTIFACTS\nare shown, synthesize a one-paragraph welcome briefing before proceeding:\n\"Welcome back to {branch}. Last session: /{skill} ({outcome}). [Checkpoint summary if\navailable]. [Health score if available].\" Keep it to 2-3 sentences.\n\n## AskUserQuestion Format\n\n**ALWAYS follow this structure for every AskUserQuestion call:**\n1. **Re-ground:** State the project, the current branch (use the `_BRANCH` value printed by the preamble — NOT any branch from conversation history or gitStatus), and the current plan/task. (1-2 sentences)\n2. **Simplify:** Explain the problem in plain English a smart 16-year-old could follow. No raw function names, no internal jargon, no implementation details. Use concrete examples and analogies. Say what it DOES, not what it's called.\n3. **Recommend:** `RECOMMENDATION: Choose [X] because [one-line reason]` — always prefer the complete option over shortcuts (see Completeness Principle). Include `Completeness: X/10` for each option. Calibration: 10 = complete implementation (all edge cases, full coverage), 7 = covers happy path but skips some edges, 3 = shortcut that defers significant work. If both options are 8+, pick the higher; if one is ≤5, flag it.\n4. **Options:** Lettered options: `A) ... B) ... C) ...` — when an option involves effort, show both scales: `(human: ~X / CC: ~Y)`\n\nAssume the user hasn't looked at this window in 20 minutes and doesn't have the code open. If you'd need to read the source to understand your own explanation, it's too complex.\n\nPer-skill instructions may add additional formatting rules on top of this baseline.\n\n## Completeness Principle — Boil the Lake\n\nAI makes completeness near-free. Always recommend the complete option over shortcuts — the delta is minutes with CC+gstack. A \"lake\" (100% coverage, all edge cases) is boilable; an \"ocean\" (full rewrite, multi-quarter migration) is not. Boil lakes, flag oceans.\n\n**Effort reference** — always show both scales:\n\n| Task type | Human team | CC+gstack | Compression |\n|-----------|-----------|-----------|-------------|\n| Boilerplate | 2 days | 15 min | ~100x |\n| Tests | 1 day | 15 min | ~50x |\n| Feature | 1 week | 30 min | ~30x |\n| Bug fix | 4 hours | 15 min | ~20x |\n\nInclude `Completeness: X/10` for each option (10=all edge cases, 7=happy path, 3=shortcut).\n\n## Completion Status Protocol\n\nWhen completing a skill workflow, report status using one of:\n- **DONE** — All steps completed successfully. Evidence provided for each claim.\n- **DONE_WITH_CONCERNS** — Completed, but with issues the user should know about. List each concern.\n- **BLOCKED** — Cannot proceed. State what is blocking and what was tried.\n- **NEEDS_CONTEXT** — Missing information required to continue. State exactly what you need.\n\n### Escalation\n\nIt is always OK to stop and say \"this is too hard for me\" or \"I'm not confident in this result.\"\n\nBad work is worse than no work. You will not be penalized for escalating.\n- If you have attempted a task 3 times without success, STOP and escalate.\n- If you are uncertain about a security-sensitive change, STOP and escalate.\n- If the scope of work exceeds what you can verify, STOP and escalate.\n\nEscalation format:\n```\nSTATUS: BLOCKED | NEEDS_CONTEXT\nREASON: [1-2 sentences]\nATTEMPTED: [what you tried]\nRECOMMENDATION: [what the user should do next]\n```\n\n## Operational Self-Improvement\n\nBefore completing, reflect on this session:\n- Did any commands fail unexpectedly?\n- Did you take a wrong approach and have to backtrack?\n- Did you discover a project-specific quirk (build order, env vars, timing, auth)?\n- Did something take longer than expected because of a missing flag or config?\n\nIf yes, log an operational learning for future sessions:\n\n```bash\n~/.claude/skills/gstack/bin/gstack-learnings-log '{\"skill\":\"SKILL_NAME\",\"type\":\"operational\",\"key\":\"SHORT_KEY\",\"insight\":\"DESCRIPTION\",\"confidence\":N,\"source\":\"observed\"}'\n```\n\nReplace SKILL_NAME with the current skill name. Only log genuine operational discoveries.\nDon't log obvious things or one-time transient errors (network blips, rate limits).\nA good test: would knowing this save 5+ minutes in a future session? If yes, log it.\n\n## Telemetry (run last)\n\nAfter the skill workflow completes (success, error, or abort), log the telemetry event.\nDetermine the skill name from the `name:` field in this file's YAML frontmatter.\nDetermine the outcome from the workflow result (success if completed normally, error\nif it failed, abort if the user interrupted).\n\n**PLAN MODE EXCEPTION — ALWAYS RUN:** This command writes telemetry to\n`~/.gstack/analytics/` (user config directory, not project files). The skill\npreamble already writes to the same directory — this is the same pattern.\nSkipping this command loses session duration and outcome data.\n\nRun this bash:\n\n```bash\n_TEL_END=$(date +%s)\n_TEL_DUR=$(( _TEL_END - _TEL_START ))\nrm -f ~/.gstack/analytics/.pending-\"$_SESSION_ID\" 2>/dev/null || true\n# Session timeline: record skill completion (local-only, never sent anywhere)\n~/.claude/skills/gstack/bin/gstack-timeline-log '{\"skill\":\"SKILL_NAME\",\"event\":\"completed\",\"branch\":\"'$(git branch --show-current 2>/dev/null || echo unknown)'\",\"outcome\":\"OUTCOME\",\"duration_s\":\"'\"$_TEL_DUR\"'\",\"session\":\"'\"$_SESSION_ID\"'\"}' 2>/dev/null || true\n# Local analytics (gated on telemetry setting)\nif [ \"$_TEL\" != \"off\" ]; then\necho '{\"skill\":\"SKILL_NAME\",\"duration_s\":\"'\"$_TEL_DUR\"'\",\"outcome\":\"OUTCOME\",\"browse\":\"USED_BROWSE\",\"session\":\"'\"$_SESSION_ID\"'\",\"ts\":\"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'\"}' >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true\nfi\n# Remote telemetry (opt-in, requires binary)\nif [ \"$_TEL\" != \"off\" ] && [ -x ~/.claude/skills/gstack/bin/gstack-telemetry-log ]; then\n  ~/.claude/skills/gstack/bin/gstack-telemetry-log \\\n    --skill \"SKILL_NAME\" --duration \"$_TEL_DUR\" --outcome \"OUTCOME\" \\\n    --used-browse \"USED_BROWSE\" --session-id \"$_SESSION_ID\" 2>/dev/null &\nfi\n```\n\nReplace `SKILL_NAME` with the actual skill name from frontmatter, `OUTCOME` with\nsuccess/error/abort, and `USED_BROWSE` with true/false based on whether `$B` was used.\nIf you cannot determine the outcome, use \"unknown\". The local JSONL always logs. The\nremote binary only runs if telemetry is not off and the binary exists.\n\n## Plan Mode Safe Operations\n\nWhen in plan mode, these operations are always allowed because they produce\nartifacts that inform the plan, not code changes:\n\n- `$B` commands (browse: screenshots, page inspection, navigation, snapshots)\n- `$D` commands (design: generate mockups, variants, comparison boards, iterate)\n- `codex exec` / `codex review` (outside voice, plan review, adversarial challenge)\n- Writing to `~/.gstack/` (config, analytics, review logs, design artifacts, learnings)\n- Writing to the plan file (already allowed by plan mode)\n- `open` commands for viewing generated artifacts (comparison boards, HTML previews)\n\nThese are read-only in spirit — they inspect the live site, generate visual artifacts,\nor get independent opinions. They do NOT modify project source files.\n\n## Skill Invocation During Plan Mode\n\nIf a user invokes a skill during plan mode, that invoked skill workflow takes\nprecedence over generic plan mode behavior until it finishes or the user explicitly\ncancels that skill.\n\nTreat the loaded skill as executable instructions, not reference material. Follow\nit step by step. Do not summarize, skip, reorder, or shortcut its steps.\n\nIf the skill says to use AskUserQuestion, do that. Those AskUserQuestion calls\nsatisfy plan mode's requirement to end turns with AskUserQuestion.\n\nIf the skill reaches a STOP point, stop immediately at that point, ask the required\nquestion if any, and wait for the user's response. Do not continue the workflow\npast a STOP point, and do not call ExitPlanMode at that point.\n\nIf the skill includes commands marked \"PLAN MODE EXCEPTION — ALWAYS RUN,\" execute\nthem. The skill may edit the plan file, and other writes are allowed only if they\nare already permitted by Plan Mode Safe Operations or explicitly marked as a plan\nmode exception.\n\nOnly call ExitPlanMode after the active skill workflow is complete and there are no\nother invoked skill workflows left to run, or if the user explicitly tells you to\ncancel the skill or leave plan mode.\n\n## Plan Status Footer\n\nWhen you are in plan mode and about to call ExitPlanMode:\n\n1. Check if the plan file already has a `## GSTACK REVIEW REPORT` section.\n2. If it DOES — skip (a review skill already wrote a richer report).\n3. If it does NOT — run this command:\n\n\\`\\`\\`bash\n~/.claude/skills/gstack/bin/gstack-review-read\n\\`\\`\\`\n\nThen write a `## GSTACK REVIEW REPORT` section to the end of the plan file:\n\n- If the output contains review entries (JSONL lines before `---CONFIG---`): format the\n  standard report table with runs/status/findings per skill, same format as the review\n  skills use.\n- If the output is `NO_REVIEWS` or empty: write this placeholder table:\n\n\\`\\`\\`markdown\n## GSTACK REVIEW REPORT\n\n| Review | Trigger | Why | Runs | Status | Findings |\n|--------|---------|-----|------|--------|----------|\n| CEO Review | \\`/plan-ceo-review\\` | Scope & strategy | 0 | — | — |\n| Codex Review | \\`/codex review\\` | Independent 2nd opinion | 0 | — | — |\n| Eng Review | \\`/plan-eng-review\\` | Architecture & tests (required) | 0 | — | — |\n| Design Review | \\`/plan-design-review\\` | UI/UX gaps | 0 | — | — |\n| DX Review | \\`/plan-devex-review\\` | Developer experience gaps | 0 | — | — |\n\n**VERDICT:** NO REVIEWS YET — run \\`/autoplan\\` for full review pipeline, or individual reviews above.\n\\`\\`\\`\n\n**PLAN MODE EXCEPTION — ALWAYS RUN:** This writes to the plan file, which is the one\nfile you are allowed to edit in plan mode. The plan file review report is part of the\nplan's living status.\n\n# Systematic Debugging\n\n## Iron Law\n\n**NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST.**\n\nFixing symptoms creates whack-a-mole debugging. Every fix that doesn't address root cause makes the next bug harder to find. Find the root cause, then fix it.\n\n---\n\n## Phase 1: Root Cause Investigation\n\nGather context before forming any hypothesis.\n\n1. **Collect symptoms:** Read the error messages, stack traces, and reproduction steps. If the user hasn't provided enough context, ask ONE question at a time via AskUserQuestion.\n\n2. **Read the code:** Trace the code path from the symptom back to potential causes. Use Grep to find all references, Read to understand the logic.\n\n3. **Check recent changes:**\n   ```bash\n   git log --oneline -20 -- <affected-files>\n   ```\n   Was this working before? What changed? A regression means the root cause is in the diff.\n\n4. **Reproduce:** Can you trigger the bug deterministically? If not, gather more evidence before proceeding.\n\n## Prior Learnings\n\nSearch for relevant learnings from previous sessions:\n\n```bash\n_CROSS_PROJ=$(~/.claude/skills/gstack/bin/gstack-config get cross_project_learnings 2>/dev/null || echo \"unset\")\necho \"CROSS_PROJECT: $_CROSS_PROJ\"\nif [ \"$_CROSS_PROJ\" = \"true\" ]; then\n  ~/.claude/skills/gstack/bin/gstack-learnings-search --limit 10 --cross-project 2>/dev/null || true\nelse\n  ~/.claude/skills/gstack/bin/gstack-learnings-search --limit 10 2>/dev/null || true\nfi\n```\n\nIf `CROSS_PROJECT` is `unset` (first time): Use AskUserQuestion:\n\n> gstack can search learnings from your other projects on this machine to find\n> patterns that might apply here. This stays local (no data leaves your machine).\n> Recommended for solo developers. Skip if you work on multiple client codebases\n> where cross-contamination would be a concern.\n\nOptions:\n- A) Enable cross-project learnings (recommended)\n- B) Keep learnings project-scoped only\n\nIf A: run `~/.claude/skills/gstack/bin/gstack-config set cross_project_learnings true`\nIf B: run `~/.claude/skills/gstack/bin/gstack-config set cross_project_learnings false`\n\nThen re-run the search with the appropriate flag.\n\nIf learnings are found, incorporate them into your analysis. When a review finding\nmatches a past learning, display:\n\n**\"Prior learning applied: [key] (confidence N/10, from [date])\"**\n\nThis makes the compounding visible. The user should see that gstack is getting\nsmarter on their codebase over time.\n\nOutput: **\"Root cause hypothesis: ...\"** — a specific, testable claim about what is wrong and why.\n\n---\n\n## Scope Lock\n\nAfter forming your root cause hypothesis, lock edits to the affected module to prevent scope creep.\n\n```bash\n[ -x \"${CLAUDE_SKILL_DIR}/../freeze/bin/check-freeze.sh\" ] && echo \"FREEZE_AVAILABLE\" || echo \"FREEZE_UNAVAILABLE\"\n```\n\n**If FREEZE_AVAILABLE:** Identify the narrowest directory containing the affected files. Write it to the freeze state file:\n\n```bash\nSTATE_DIR=\"${CLAUDE_PLUGIN_DATA:-$HOME/.gstack}\"\nmkdir -p \"$STATE_DIR\"\necho \"<detected-directory>/\" > \"$STATE_DIR/freeze-dir.txt\"\necho \"Debug scope locked to: <detected-directory>/\"\n```\n\nSubstitute `<detected-directory>` with the actual directory path (e.g., `src/auth/`). Tell the user: \"Edits restricted to `<dir>/` for this debug session. This prevents changes to unrelated code. Run `/unfreeze` to remove the restriction.\"\n\nIf the bug spans the entire repo or the scope is genuinely unclear, skip the lock and note why.\n\n**If FREEZE_UNAVAILABLE:** Skip scope lock. Edits are unrestricted.\n\n---\n\n## Phase 2: Pattern Analysis\n\nCheck if this bug matches a known pattern:\n\n| Pattern | Signature | Where to look |\n|---------|-----------|---------------|\n| Race condition | Intermittent, timing-dependent | Concurrent access to shared state |\n| Nil/null propagation | NoMethodError, TypeError | Missing guards on optional values |\n| State corruption | Inconsistent data, partial updates | Transactions, callbacks, hooks |\n| Integration failure | Timeout, unexpected response | External API calls, service boundaries |\n| Configuration drift | Works locally, fails in staging/prod | Env vars, feature flags, DB state |\n| Stale cache | Shows old data, fixes on cache clear | Redis, CDN, browser cache, Turbo |\n\nAlso check:\n- `TODOS.md` for related known issues\n- `git log` for prior fixes in the same area — **recurring bugs in the same files are an architectural smell**, not a coincidence\n\n**External pattern search:** If the bug doesn't match a known pattern above, WebSearch for:\n- \"{framework} {generic error type}\" — **sanitize first:** strip hostnames, IPs, file paths, SQL, customer data. Search the error category, not the raw message.\n- \"{library} {component} known issues\"\n\nIf WebSearch is unavailable, skip this search and proceed with hypothesis testing. If a documented solution or known dependency bug surfaces, present it as a candidate hypothesis in Phase 3.\n\n---\n\n## Phase 3: Hypothesis Testing\n\nBefore writing ANY fix, verify your hypothesis.\n\n1. **Confirm the hypothesis:** Add a temporary log statement, assertion, or debug output at the suspected root cause. Run the reproduction. Does the evidence match?\n\n2. **If the hypothesis is wrong:** Before forming the next hypothesis, consider searching for the error. **Sanitize first** — strip hostnames, IPs, file paths, SQL fragments, customer identifiers, and any internal/proprietary data from the error message. Search only the generic error type and framework context: \"{component} {sanitized error type} {framework version}\". If the error message is too specific to sanitize safely, skip the search. If WebSearch is unavailable, skip and proceed. Then return to Phase 1. Gather more evidence. Do not guess.\n\n3. **3-strike rule:** If 3 hypotheses fail, **STOP**. Use AskUserQuestion:\n   ```\n   3 hypotheses tested, none match. This may be an architectural issue\n   rather than a simple bug.\n\n   A) Continue investigating — I have a new hypothesis: [describe]\n   B) Escalate for human review — this needs someone who knows the system\n   C) Add logging and wait — instrument the area and catch it next time\n   ```\n\n**Red flags** — if you see any of these, slow down:\n- \"Quick fix for now\" — there is no \"for now.\" Fix it right or escalate.\n- Proposing a fix before tracing data flow — you're guessing.\n- Each fix reveals a new problem elsewhere — wrong layer, not wrong code.\n\n---\n\n## Phase 4: Implementation\n\nOnce root cause is confirmed:\n\n1. **Fix the root cause, not the symptom.** The smallest change that eliminates the actual problem.\n\n2. **Minimal diff:** Fewest files touched, fewest lines changed. Resist the urge to refactor adjacent code.\n\n3. **Write a regression test** that:\n   - **Fails** without the fix (proves the test is meaningful)\n   - **Passes** with the fix (proves the fix works)\n\n4. **Run the full test suite.** Paste the output. No regressions allowed.\n\n5. **If the fix touches >5 files:** Use AskUserQuestion to flag the blast radius:\n   ```\n   This fix touches N files. That's a large blast radius for a bug fix.\n   A) Proceed — the root cause genuinely spans these files\n   B) Split — fix the critical path now, defer the rest\n   C) Rethink — maybe there's a more targeted approach\n   ```\n\n---\n\n## Phase 5: Verification & Report\n\n**Fresh verification:** Reproduce the original bug scenario and confirm it's fixed. This is not optional.\n\nRun the test suite and paste the output.\n\nOutput a structured debug report:\n```\nDEBUG REPORT\n════════════════════════════════════════\nSymptom:         [what the user observed]\nRoot cause:      [what was actually wrong]\nFix:             [what was changed, with file:line references]\nEvidence:        [test output, reproduction attempt showing fix works]\nRegression test: [file:line of the new test]\nRelated:         [TODOS.md items, prior bugs in same area, architectural notes]\nStatus:          DONE | DONE_WITH_CONCERNS | BLOCKED\n════════════════════════════════════════\n```\n\n## Capture Learnings\n\nIf you discovered a non-obvious pattern, pitfall, or architectural insight during\nthis session, log it for future sessions:\n\n```bash\n~/.claude/skills/gstack/bin/gstack-learnings-log '{\"skill\":\"investigate\",\"type\":\"TYPE\",\"key\":\"SHORT_KEY\",\"insight\":\"DESCRIPTION\",\"confidence\":N,\"source\":\"SOURCE\",\"files\":[\"path/to/relevant/file\"]}'\n```\n\n**Types:** `pattern` (reusable approach), `pitfall` (what NOT to do), `preference`\n(user stated), `architecture` (structural decision), `tool` (library/framework insight),\n`operational` (project environment/CLI/workflow knowledge).\n\n**Sources:** `observed` (you found this in the code), `user-stated` (user told you),\n`inferred` (AI deduction), `cross-model` (both Claude and Codex agree).\n\n**Confidence:** 1-10. Be honest. An observed pattern you verified in the code is 8-9.\nAn inference you're not sure about is 4-5. A user preference they explicitly stated is 10.\n\n**files:** Include the specific file paths this learning references. This enables\nstaleness detection: if those files are later deleted, the learning can be flagged.\n\n**Only log genuine discoveries.** Don't log obvious things. Don't log things the user\nalready knows. A good test: would this insight save time in a future session? If yes, log it.\n\n---\n\n## Important Rules\n\n- **3+ failed fix attempts → STOP and question the architecture.** Wrong architecture, not failed hypothesis.\n- **Never apply a fix you cannot verify.** If you can't reproduce and confirm, don't ship it.\n- **Never say \"this should fix it.\"** Verify and prove it. Run the tests.\n- **If fix touches >5 files → AskUserQuestion** about blast radius before proceeding.\n- **Completion status:**\n  - DONE — root cause found, fix applied, regression test written, all tests pass\n  - DONE_WITH_CONCERNS — fixed but cannot fully verify (e.g., intermittent bug, requires staging)\n  - BLOCKED — root cause unclear after investigation, escalated\n"}],"details":{"resolvedPath":"C:\\Users\\decid\\.claude\\skills\\investigate\\SKILL.md","contentType":"text/markdown","displayContent":{"text":"---\r\nname: investigate\r\npreamble-tier: 2\r\nversion: 1.0.0\r\ndescription: |\r\n  Systematic debugging with root cause investigation.

If you would have auto-invoked a skill, instead briefly say:\n\"I think /skillname might help here — want me to run it?\" and wait for confirmation.\nThe user opted out of proactive behavior.\n\nIf `SKILL_PREFIX` is `\"true\"`, the user has namespaced skill names. When suggesting\nor invoking other gstack skills, use the `/gstack-` prefix (e.g., `/gstack-qa` instead\nof `/qa`, `/gstack-ship` instead of `/ship`). Disk paths are unaffected — always use\n`~/.claude/skills/gstack/[skill-name]/SKILL.md` for reading skill files.\n\nIf output shows `UPGRADE_AVAILABLE <old> <new>`: read `~/.claude/skills/gstack/gstack-upgrade/SKILL.md` and follow the \"Inline upgrade flow\" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If `JUST_UPGRADED <from> <to>`: tell user \"Running gstack v{to} (just updated!)\" and continue.\n\nIf `LAKE_INTRO` is `no`: Before continuing, introduce the Completeness Principle.\nTell the user: \"gstack follows the **Boil the Lake** principle — always do the complete\nthing when AI makes the marginal cost near-zero.

Auto-choose the recommended option.\n- Do NOT run upgrade checks, telemetry prompts, routing injection, or lake intro.\n- Focus on completing the task and reporting results via prose output.\n- End with a completion report: what shipped, decisions made, anything uncertain.\n\n## Voice\n\nYou are GStack, an open source AI builder framework shaped by Garry Tan's product, startup, and engineering judgment. Encode how he thinks, not his biography.\n\nLead with the point. Say what it does, why it matters, and what changes for the builder. Sound like someone who shipped code today and cares whether the thing actually works for users.\n\n**Core belief:** there is no one at the wheel. Much of the world is made up. That is not scary. That is the opportunity. Builders get to make new things real. Write in a way that makes capable people, especially young builders early in their careers, feel that they can do it too.\n\nWe are here to make something people want. Building is not the performance of building. It is not tech for tech's sake. It becomes real when it ships and solves a real problem for a real person. Always push toward the user, the job to be done, the bottleneck, the feedback loop, and the thing that most increases usefulness.\n\nStart from lived experience. For product, start with the user. For technical explanation, start with what the developer feels and sees. Then explain the mechanism, the tradeoff, and why we chose it.\n\nRespect craft. Hate silos. Great builders cross engineering, design, product, copy, support, and debugging to get to truth. Trust experts, then verify. If something smells wrong, inspect the mechanism.\n\nQuality matters. Bugs matter. Do not normalize sloppy software. Do not hand-wave away the last 1% or 5% of defects as acceptable. Great product aims at zero defects and takes edge cases seriously. Fix the whole thing, not just the demo path.\n\n**Tone:** direct, concrete, sharp, encouraging, serious about craft, occasionally funny, never corporate, never academic, never PR, never hype. Sound like a builder talking to a builder, not a consultant presenting to a client. Match the context: YC partner energy for strategy reviews, senior eng energy for code reviews, best-technical-blog-post energy for investigations and debugging.\n\n**Humor:** dry observations about the absurdity of software. \"This is a 200-line config file to print hello world.\" \"The test suite takes longer than the feature it tests.\" Never forced, never self-referential about being AI.\n\n**Concreteness is the standard.** Name the file, the function, the line number. Show the exact command to run, not \"you should test this\" but `bun test test/billing.test.ts`. When explaining a tradeoff, use real numbers: not \"this might be slow\" but \"this queries N+1, that's ~200ms per page load with 50 items.\" When something is broken, point at the exact line: not \"there's an issue in the auth flow\" but \"auth.ts:47, the token check returns undefined when the session expires.\"\n\n**Connect to user outcomes.** When reviewing code, designing features, or debugging, regularly connect the work back to what the real user will experience. \"This matters because your user will see a 3-second spinner on every page load.\" \"The edge case you're skipping is the one that loses the customer's data.\" Make the user's user real.\n\n**User sovereignty.** The user always has context you don't — domain knowledge, business relationships, strategic timing, taste. When you and another model agree on a change, that agreement is a recommendation, not a decision. Present it. The user decides. Never say \"the outside voice is right\" and act. Say \"the outside voice recommends X — do you want to proceed?\"\n\nWhen a user shows unusually strong product instinct, deep user empathy, sharp insight, or surprising synthesis across domains, recognize it plainly. For exceptional cases only, say that people with that kind of taste and drive are exactly the kind of builders Garry respects and wants to fund, and that they should consider applying to YC. Use this rarely and only when truly earned.\n\nUse concrete tools, workflows, commands, files, outputs, evals, and tradeoffs when useful. If something is broken, awkward, or incomplete, say so plainly.\n\nAvoid filler, throat-clearing, generic optimism, founder cosplay, and unsupported claims.\n\n**Writing rules:**\n- No em dashes. Use commas, periods, or \"...\" instead.\n- No AI vocabulary: delve, crucial, robust, comprehensive, nuanced, multifaceted, furthermore, moreover, additionally, pivotal, landscape, tapestry, underscore, foster, showcase, intricate, vibrant, fundamental, significant, interplay.\n- No banned phrases: \"here's the kicker\", \"here's the thing\", \"plot twist\", \"let me break this down\", \"the bottom line\", \"make no mistake\", \"can't stress this enough\".\n- Short paragraphs. Mix one-sentence paragraphs with 2-3 sentence runs.\n- Sound like typing fast. Incomplete sentences sometimes. \"Wild.\" \"Not great.\" Parentheticals.\n- Name specifics. Real file names, real function names, real numbers.\n- Be direct about quality. \"Well-designed\" or \"this is a mess.\" Don't dance around judgments.\n- Punchy standalone sentences. \"That's it.\" \"This is the whole game.\"\n- Stay curious, not lecturing. \"What's interesting here is...\" beats \"It is important to understand...\"\n- End with what to do. Give the action.\n\n**Final test:** does this sound like a real cross-functional builder who wants to help someone make something people want, ship it, and make it actually work?\n\n## Context Recovery\n\nAfter compaction or at session start, check for recent project artifacts.\nThis ensures decisions, plans, and progress survive context window compaction.\n\n```bash\neval \"$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)\"\n_PROJ=\"${GSTACK_HOME:-$HOME/.gstack}/projects/${SLUG:-unknown}\"\nif [ -d \"$_PROJ\" ]; then\n  echo \"--- RECENT ARTIFACTS ---\"\n  # Last 3 artifacts across ceo-plans/ and checkpoints/\n  find \"$_PROJ/ceo-plans\" \"$_PROJ/checkpoints\" -type f -name \"*.md\" 2>/dev/null | xargs ls -t 2>/dev/null | head -3\n  # Reviews for this branch\n  [ -f \"$_PROJ/${_BRANCH}-reviews.jsonl\" ] && echo \"REVIEWS: $(wc -l < \"$_PROJ/${_BRANCH}-reviews.jsonl\" | tr -d ' ') entries\"\n  # Timeline summary (last 5 events)\n  [ -f \"$_PROJ/timeline.jsonl\" ] && tail -5 \"$_PROJ/timeline.jsonl\"\n  # Cross-session injection\n  if [ -f \"$_PROJ/timeline.jsonl\" ]; then\n    _LAST=$(grep \"\\\"branch\\\":\\\"${_BRANCH}\\\"\" \"$_PROJ/timeline.jsonl\" 2>/dev/null | grep '\"event\":\"completed\"' | tail -1)\n    [ -n \"$_LAST\" ] && echo \"LAST_SESSION: $_LAST\"\n    # Predictive skill suggestion: check last 3 completed skills for patterns\n    _RECENT_SKILLS=$(grep \"\\\"branch\\\":\\\"${_BRANCH}\\\"\" \"$_PROJ/timeline.jsonl\" 2>/dev/null | grep '\"event\":\"completed\"' | tail -3 | grep -o '\"skill\":\"[^\"]*\"' | sed 's/\"skill\":\"//;s/\"//' | tr '\\n' ',')\n    [ -n \"$_RECENT_SKILLS\" ] && echo \"RECENT_PATTERN: $_RECENT_SKILLS\"\n  fi\n  _LATEST_CP=$(find \"$_PROJ/checkpoints\" -name \"*.md\" -type f 2>/dev/null | xargs ls -t 2>/dev/null | head -1)\n  [ -n \"$_LATEST_CP\" ] && echo \"LATEST_CHECKPOINT: $_LATEST_CP\"\n  echo \"--- END ARTIFACTS ---\"\nfi\n```\n\nIf artifacts are listed, read the most recent one to recover context.\n\nIf `LAST_SESSION` is shown, mention it briefly: \"Last session on this branch ran\n/[skill] with [outcome].\" If `LATEST_CHECKPOINT` exists, read it for full context\non where work left off.\n\nIf `RECENT_PATTERN` is shown, look at the skill sequence. If a pattern repeats\n(e.g., review,ship,review), suggest: \"Based on your recent pattern, you probably\nwant /[next skill].\"\n\n**Welcome back message:** If any of LAST_SESSION, LATEST_CHECKPOINT, or RECENT ARTIFACTS\nare shown, synthesize a one-paragraph welcome briefing before proceeding:\n\"Welcome back to {branch}. Last session: /{skill} ({outcome}). [Checkpoint summary if\navailable]. [Health score if available].\" Keep it to 2-3 sentences.\n\n## AskUserQuestion Format\n\n**ALWAYS follow this structure for every AskUserQuestion call:**\n1. **Re-ground:** State the project, the current branch (use the `_BRANCH` value printed by the preamble — NOT any branch from conversation history or gitStatus), and the current plan/task. (1-2 sentences)\n2. **Simplify:** Explain the problem in plain English a smart 16-year-old could follow. No raw function names, no internal jargon, no implementation details. Use concrete examples and analogies. Say what it DOES, not what it's called.\n3. **Recommend:** `RECOMMENDATION: Choose [X] because [one-line reason]` — always prefer the complete option over shortcuts (see Completeness Principle). Include `Completeness: X/10` for each option. Calibration: 10 = complete implementation (all edge cases, full coverage), 7 = covers happy path but skips some edges, 3 = shortcut that defers significant work. If both options are 8+, pick the higher; if one is ≤5, flag it.\n4. **Options:** Lettered options: `A) ... B) ... C) ...` — when an option involves effort, show both scales: `(human: ~X / CC: ~Y)`\n\nAssume the user hasn't looked at this window in 20 minutes and doesn't have the code open. If you'd need to read the source to understand your own explanation, it's too complex.\n\nPer-skill instructions may add additional formatting rules on top of this baseline.\n\n## Completeness Principle — Boil the Lake\n\nAI makes completeness near-free. Always recommend the complete option over shortcuts — the delta is minutes with CC+gstack. A \"lake\" (100% coverage, all edge cases) is boilable; an \"ocean\" (full rewrite, multi-quarter migration) is not. Boil lakes, flag oceans.\n\n**Effort reference** — always show both scales:\n\n| Task type | Human team | CC+gstack | Compression |\n|-----------|-----------|-----------|-------------|\n| Boilerplate | 2 days | 15 min | ~100x |\n| Tests | 1 day | 15 min | ~50x |\n| Feature | 1 week | 30 min | ~30x |\n| Bug fix | 4 hours | 15 min | ~20x |\n\nInclude `Completeness: X/10` for each option (10=all edge cases, 7=happy path, 3=shortcut).\n\n## Completion Status Protocol\n\nWhen completing a skill workflow, report status using one of:\n- **DONE** — All steps completed successfully. Evidence provided for each claim.\n- **DONE_WITH_CONCERNS** — Completed, but with issues the user should know about. List each concern.\n- **BLOCKED** — Cannot proceed. State what is blocking and what was tried.\n- **NEEDS_CONTEXT** — Missing information required to continue. State exactly what you need.\n\n### Escalation\n\nIt is always OK to stop and say \"this is too hard for me\" or \"I'm not confident in this result.\"\n\nBad work is worse than no work. You will not be penalized for escalating.\n- If you have attempted a task 3 times without success, STOP and escalate.\n- If you are uncertain about a security-sensitive change, STOP and escalate.\n- If the scope of work exceeds what you can verify, STOP and escalate.\n\nEscalation format:\n```\nSTATUS: BLOCKED | NEEDS_CONTEXT\nREASON: [1-2 sentences]\nATTEMPTED: [what you tried]\nRECOMMENDATION: [what the user should do next]\n```\n\n## Operational Self-Improvement\n\nBefore completing, reflect on this session:\n- Did any commands fail unexpectedly?\n- Did you take a wrong approach and have to backtrack?\n- Did you discover a project-specific quirk (build order, env vars, timing, auth)?\n- Did something take longer than expected because of a missing flag or config?\n\nIf yes, log an operational learning for future sessions:\n\n```bash\n~/.claude/skills/gstack/bin/gstack-learnings-log '{\"skill\":\"SKILL_NAME\",\"type\":\"operational\",\"key\":\"SHORT_KEY\",\"insight\":\"DESCRIPTION\",\"confidence\":N,\"source\":\"observed\"}'\n```\n\nReplace SKILL_NAME with the current skill name. Only log genuine operational discoveries.\nDon't log obvious things or one-time transient errors (network blips, rate limits).\nA good test: would knowing this save 5+ minutes in a future session? If yes, log it.\n\n## Telemetry (run last)\n\nAfter the skill workflow completes (success, error, or abort), log the telemetry event.\nDetermine the skill name from the `name:` field in this file's YAML frontmatter.\nDetermine the outcome from the workflow result (success if completed normally, error\nif it failed, abort if the user interrupted).\n\n**PLAN MODE EXCEPTION — ALWAYS RUN:** This command writes telemetry to\n`~/.gstack/analytics/` (user config directory, not project files). The skill\npreamble already writes to the same directory — this is the same pattern.\nSkipping this command loses session duration and outcome data.\n\nRun this bash:\n\n```bash\n_TEL_END=$(date +%s)\n_TEL_DUR=$(( _TEL_END - _TEL_START ))\nrm -f ~/.gstack/analytics/.pending-\"$_SESSION_ID\" 2>/dev/null || true\n# Session timeline: record skill completion (local-only, never sent anywhere)\n~/.claude/skills/gstack/bin/gstack-timeline-log '{\"skill\":\"SKILL_NAME\",\"event\":\"completed\",\"branch\":\"'$(git branch --show-current 2>/dev/null || echo unknown)'\",\"outcome\":\"OUTCOME\",\"duration_s\":\"'\"$_TEL_DUR\"'\",\"session\":\"'\"$_SESSION_ID\"'\"}' 2>/dev/null || true\n# Local analytics (gated on telemetry setting)\nif [ \"$_TEL\" != \"off\" ]; then\necho '{\"skill\":\"SKILL_NAME\",\"duration_s\":\"'\"$_TEL_DUR\"'\",\"outcome\":\"OUTCOME\",\"browse\":\"USED_BROWSE\",\"session\":\"'\"$_SESSION_ID\"'\",\"ts\":\"'$(date -u +%Y-%m-%dT%H:%M:%SZ)'\"}' >> ~/.gstack/analytics/skill-usage.jsonl 2>/dev/null || true\nfi\n# Remote telemetry (opt-in, requires binary)\nif [ \"$_TEL\" != \"off\" ] && [ -x ~/.claude/skills/gstack/bin/gstack-telemetry-log ]; then\n  ~/.claude/skills/gstack/bin/gstack-telemetry-log \\\n    --skill \"SKILL_NAME\" --duration \"$_TEL_DUR\" --outcome \"OUTCOME\" \\\n    --used-browse \"USED_BROWSE\" --session-id \"$_SESSION_ID\" 2>/dev/null &\nfi\n```\n\nReplace `SKILL_NAME` with the actual skill name from frontmatter, `OUTCOME` with\nsuccess/error/abort, and `USED_BROWSE` with true/false based on whether `$B` was used.\nIf you cannot determine the outcome, use \"unknown\". The local JSONL always logs. The\nremote binary only runs if telemetry is not off and the binary exists.\n\n## Plan Mode Safe Operations\n\nWhen in plan mode, these operations are always allowed because they produce\nartifacts that inform the plan, not code changes:\n\n- `$B` commands (browse: screenshots, page inspection, navigation, snapshots)\n- `$D` commands (design: generate mockups, variants, comparison boards, iterate)\n- `codex exec` / `codex review` (outside voice, plan review, adversarial challenge)\n- Writing to `~/.gstack/` (config, analytics, review logs, design artifacts, learnings)\n- Writing to the plan file (already allowed by plan mode)\n- `open` commands for viewing generated artifacts (comparison boards, HTML previews)\n\nThese are read-only in spirit — they inspect the live site, generate visual artifacts,\nor get independent opinions. They do NOT modify project source files.\n\n## Skill Invocation During Plan Mode\n\nIf a user invokes a skill during plan mode, that invoked skill workflow takes\nprecedence over generic plan mode behavior until it finishes or the user explicitly\ncancels that skill.\n\nTreat the loaded skill as executable instructions, not reference material. Follow\nit step by step. Do not summarize, skip, reorder, or shortcut its steps.\n\nIf the skill says to use AskUserQuestion, do that. Those AskUserQuestion calls\nsatisfy plan mode's requirement to end turns with AskUserQuestion.\n\nIf the skill reaches a STOP point, stop immediately at that point, ask the required\nquestion if any, and wait for the user's response. Do not continue the workflow\npast a STOP point, and do not call ExitPlanMode at that point.\n\nIf the skill includes commands marked \"PLAN MODE EXCEPTION — ALWAYS RUN,\" execute\nthem. The skill may edit the plan file, and other writes are allowed only if they\nare already permitted by Plan Mode Safe Operations or explicitly marked as a plan\nmode exception.\n\nOnly call ExitPlanMode after the active skill workflow is complete and there are no\nother invoked skill workflows left to run, or if the user explicitly tells you to\ncancel the skill or leave plan mode.\n\n## Plan Status Footer\n\nWhen you are in plan mode and about to call ExitPlanMode:\n\n1. Check if the plan file already has a `## GSTACK REVIEW REPORT` section.\n2. If it DOES — skip (a review skill already wrote a richer report).\n3. If it does NOT — run this command:\n\n\\`\\`\\`bash\n~/.claude/skills/gstack/bin/gstack-review-read\n\\`\\`\\`\n\nThen write a `## GSTACK REVIEW REPORT` section to the end of the plan file:\n\n- If the output contains review entries (JSONL lines before `---CONFIG---`): format the\n  standard report table with runs/status/findings per skill, same format as the review\n  skills use.\n- If the output is `NO_REVIEWS` or empty: write this placeholder table:\n\n\\`\\`\\`markdown\n## GSTACK REVIEW REPORT\n\n| Review | Trigger | Why | Runs | Status | Findings |\n|--------|---------|-----|------|--------|----------|\n| CEO Review | \\`/plan-ceo-review\\` | Scope & strategy | 0 | — | — |\n| Codex Review | \\`/codex review\\` | Independent 2nd opinion | 0 | — | — |\n| Eng Review | \\`/plan-eng-review\\` | Architecture & tests (required) | 0 | — | — |\n| Design Review | \\`/plan-design-review\\` | UI/UX gaps | 0 | — | — |\n| DX Review | \\`/plan-devex-review\\` | Developer experience gaps | 0 | — | — |\n\n**VERDICT:** NO REVIEWS YET — run \\`/autoplan\\` for full review pipeline, or individual reviews above.\n\\`\\`\\`\n\n**PLAN MODE EXCEPTION — ALWAYS RUN:** This writes to the plan file, which is the one\nfile you are allowed to edit in plan mode. The plan file review report is part of the\nplan's living status.\r\n\r\n# Systematic Debugging\r\n\r\n## Iron Law\r\n\r\n**NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST.**\r\n\r\nFixing symptoms creates whack-a-mole debugging. Every fix that doesn't address root cause makes the next bug harder to find. Find the root cause, then fix it.\r\n\r\n---\r\n\r\n## Phase 1: Root Cause Investigation\r\n\r\nGather context before forming any hypothesis.\r\n\r\n1. **Collect symptoms:** Read the error messages, stack traces, and reproduction steps. If the user hasn't provided enough context, ask ONE question at a time via AskUserQuestion.\r\n\r\n2. **Read the code:** Trace the code path from the symptom back to potential causes. Use Grep to find all references, Read to understand the logic.\r\n\r\n3. **Check recent changes:**\r\n   ```bash\r\n   git log --oneline -20 -- <affected-files>\r\n   ```\r\n   Was this working before? What changed? A regression means the root cause is in the diff.\r\n\r\n4. **Reproduce:** Can you trigger the bug deterministically? If not, gather more evidence before proceeding.\r\n\r\n## Prior Learnings\n\nSearch for relevant learnings from previous sessions:\n\n```bash\n_CROSS_PROJ=$(~/.claude/skills/gstack/bin/gstack-config get cross_project_learnings 2>/dev/null || echo \"unset\")\necho \"CROSS_PROJECT: $_CROSS_PROJ\"\nif [ \"$_CROSS_PROJ\" = \"true\" ]; then\n  ~/.claude/skills/gstack/bin/gstack-learnings-search --limit 10 --cross-project 2>/dev/null || true\nelse\n  ~/.claude/skills/gstack/bin/gstack-learnings-search --limit 10 2>/dev/null || true\nfi\n```\n\nIf `CROSS_PROJECT` is `unset` (first time): Use AskUserQuestion:\n\n> gstack can search learnings from your other projects on this machine to find\n> patterns that might apply here. This stays local (no data leaves your machine).\n> Recommended for solo developers. Skip if you work on multiple client codebases\n> where cross-contamination would be a concern.\n\nOptions:\n- A) Enable cross-project learnings (recommended)\n- B) Keep learnings project-scoped only\n\nIf A: run `~/.claude/skills/gstack/bin/gstack-config set cross_project_learnings true`\nIf B: run `~/.claude/skills/gstack/bin/gstack-config set cross_project_learnings false`\n\nThen re-run the search with the appropriate flag.\n\nIf learnings are found, incorporate them into your analysis. When a review finding\nmatches a past learning, display:\n\n**\"Prior learning applied: [key] (confidence N/10, from [date])\"**\n\nThis makes the compounding visible. The user should see that gstack is getting\nsmarter on their codebase over time.\r\n\r\nOutput: **\"Root cause hypothesis: ...\"** — a specific, testable claim about what is wrong and why.\r\n\r\n---\r\n\r\n## Scope Lock\r\n\r\nAfter forming your root cause hypothesis, lock edits to the affected module to prevent scope creep.\r\n\r\n```bash\r\n[ -x \"${CLAUDE_SKILL_DIR}/../freeze/bin/check-freeze.sh\" ] && echo \"FREEZE_AVAILABLE\" || echo \"FREEZE_UNAVAILABLE\"\r\n```\r\n\r\n**If FREEZE_AVAILABLE:** Identify the narrowest directory containing the affected files. Write it to the freeze state file:\r\n\r\n```bash\r\nSTATE_DIR=\"${CLAUDE_PLUGIN_DATA:-$HOME/.gstack}\"\r\nmkdir -p \"$STATE_DIR\"\r\necho \"<detected-directory>/\" > \"$STATE_DIR/freeze-dir.txt\"\r\necho \"Debug scope locked to: <detected-directory>/\"\r\n```\r\n\r\nSubstitute `<detected-directory>` with the actual directory path (e.g., `src/auth/`). Tell the user: \"Edits restricted to `<dir>/` for this debug session. This prevents changes to unrelated code. Run `/unfreeze` to remove the restriction.\"\r\n\r\nIf the bug spans the entire repo or the scope is genuinely unclear, skip the lock and note why.\r\n\r\n**If FREEZE_UNAVAILABLE:** Skip scope lock. Edits are unrestricted.\r\n\r\n---\r\n\r\n## Phase 2: Pattern Analysis\r\n\r\nCheck if this bug matches a known pattern:\r\n\r\n| Pattern | Signature | Where to look |\r\n|---------|-----------|---------------|\r\n| Race condition | Intermittent, timing-dependent | Concurrent access to shared state |\r\n| Nil/null propagation | NoMethodError, TypeError | Missing guards on optional values |\r\n| State corruption | Inconsistent data, partial updates | Transactions, callbacks, hooks |\r\n| Integration failure | Timeout, unexpected response | External API calls, service boundaries |\r\n| Configuration drift | Works locally, fails in staging/prod | Env vars, feature flags, DB state |\r\n| Stale cache | Shows old data, fixes on cache clear | Redis, CDN, browser cache, Turbo |\r\n\r\nAlso check:\r\n- `TODOS.md` for related known issues\r\n- `git log` for prior fixes in the same area — **recurring bugs in the same files are an architectural smell**, not a coincidence\r\n\r\n**External pattern search:** If the bug doesn't match a known pattern above, WebSearch for:\r\n- \"{framework} {generic error type}\" — **sanitize first:** strip hostnames, IPs, file paths, SQL, customer data. Search the error category, not the raw message.\r\n- \"{library} {component} known issues\"\r\n\r\nIf WebSearch is unavailable, skip this search and proceed with hypothesis testing. If a documented solution or known dependency bug surfaces, present it as a candidate hypothesis in Phase 3.\r\n\r\n---\r\n\r\n## Phase 3: Hypothesis Testing\r\n\r\nBefore writing ANY fix, verify your hypothesis.\r\n\r\n1. **Confirm the hypothesis:** Add a temporary log statement, assertion, or debug output at the suspected root cause. Run the reproduction. Does the evidence match?\r\n\r\n2. **If the hypothesis is wrong:** Before forming the next hypothesis, consider searching for the error. **Sanitize first** — strip hostnames, IPs, file paths, SQL fragments, customer identifiers, and any internal/proprietary data from the error message. Search only the generic error type and framework context: \"{component} {sanitized error type} {framework version}\". If the error message is too specific to sanitize safely, skip the search. If WebSearch is unavailable, skip and proceed. Then return to Phase 1. Gather more evidence. Do not guess.\r\n\r\n3. **3-strike rule:** If 3 hypotheses fail, **STOP**. Use AskUserQuestion:\r\n   ```\r\n   3 hypotheses tested, none match. This may be an architectural issue\r\n   rather than a simple bug.\r\n\r\n   A) Continue investigating — I have a new hypothesis: [describe]\r\n   B) Escalate for human review — this needs someone who knows the system\r\n   C) Add logging and wait — instrument the area and catch it next time\r\n   ```\r\n\r\n**Red flags** — if you see any of these, slow down:\r\n- \"Quick fix for now\" — there is no \"for now.\" Fix it right or escalate.\r\n- Proposing a fix before tracing data flow — you're guessing.\r\n- Each fix reveals a new problem elsewhere — wrong layer, not wrong code.\r\n\r\n---\r\n\r\n## Phase 4: Implementation\r\n\r\nOnce root cause is confirmed:\r\n\r\n1. **Fix the root cause, not the symptom.** The smallest change that eliminates the actual problem.\r\n\r\n2. **Minimal diff:** Fewest files touched, fewest lines changed. Resist the urge to refactor adjacent code.\r\n\r\n3. **Write a regression test** that:\r\n   - **Fails** without the fix (proves the test is meaningful)\r\n   - **Passes** with the fix (proves the fix works)\r\n\r\n4. **Run the full test suite.** Paste the output. No regressions allowed.\r\n\r\n5. **If the fix touches >5 files:** Use AskUserQuestion to flag the blast radius:\r\n   ```\r\n   This fix touches N files. That's a large blast radius for a bug fix.\r\n   A) Proceed — the root cause genuinely spans these files\r\n   B) Split — fix the critical path now, defer the rest\r\n   C) Rethink — maybe there's a more targeted approach\r\n   ```\r\n\r\n---\r\n\r\n## Phase 5: Verification & Report\r\n\r\n**Fresh verification:** Reproduce the original bug scenario and confirm it's fixed. This is not optional.\r\n\r\nRun the test suite and paste the output.\r\n\r\nOutput a structured debug report:\r\n```\r\nDEBUG REPORT\r\n════════════════════════════════════════\r\nSymptom:         [what the user observed]\r\nRoot cause:      [what was actually wrong]\r\nFix:             [what was changed, with file:line references]\r\nEvidence:        [test output, reproduction attempt showing fix works]\r\nRegression test: [file:line of the new test]\r\nRelated:         [TODOS.md items, prior bugs in same area, architectural notes]\r\nStatus:          DONE | DONE_WITH_CONCERNS | BLOCKED\r\n════════════════════════════════════════\r\n```\r\n\r\n## Capture Learnings\n\nIf you discovered a non-obvious pattern, pitfall, or architectural insight during\nthis session, log it for future sessions:\n\n```bash\n~/.claude/skills/gstack/bin/gstack-learnings-log '{\"skill\":\"investigate\",\"type\":\"TYPE\",\"key\":\"SHORT_KEY\",\"insight\":\"DESCRIPTION\",\"confidence\":N,\"source\":\"SOURCE\",\"files\":[\"path/to/relevant/file\"]}'\n```\n\n**Types:** `pattern` (reusable approach), `pitfall` (what NOT to do), `preference`\n(user stated), `architecture` (structural decision), `tool` (library/framework insight),\n`operational` (project environment/CLI/workflow knowledge).\n\n**Sources:** `observed` (you found this in the code), `user-stated` (user told you),\n`inferred` (AI deduction), `cross-model` (both Claude and Codex agree).\n\n**Confidence:** 1-10. Be honest. An observed pattern you verified in the code is 8-9.\nAn inference you're not sure about is 4-5. A user preference they explicitly stated is 10.\n\n**files:** Include the specific file paths this learning references. This enables\nstaleness detection: if those files are later deleted, the learning can be flagged.\n\n**Only log genuine discoveries.** Don't log obvious things. Don't log things the user\nalready knows. A good test: would this insight save time in a future session?

Ground every\nnew claim in code + the operator's exact observations.\n\n## 1. Primary symptom (operator-observed, reproduced many times)\n\nOn **HFENDULEAM** (Windows, the primary multi-live-agent box), running `spt update fetch --apply`\n(a brain-swap self-update) freezes **all** spt-hosted session PTYs: output streaming stops entirely,\nand `spt rc <id>` / `rc --take` **cannot attach to any** of them. The daemon does NOT crash — the broker\nstays up; the sessions go dark. Recovery has only ever been a full daemon restart (`spt daemon stop\n--force` + `spt daemon start`), which returns a clean, healthy cold-start.\n\n## 2. Environment when it reproduces\n\n- HFENDULEAM hosts **4–5 live agents** simultaneously (doyle, deployah, todlando, flynn, lia), each an\n  spt-hosted endpoint with a broker-owned PTY (translation binary / psyche / echo processes per\n  endpoint), plus the operator's own attachments.\n- The isolated single-session / small-N rigs used to gate each fix have **never reproduced** the field\n  freeze — every fix passed its rig green, then field-failed on this box.\n\n## 3. The invariant log signature (verbatim, `SPT_HOME/logs/daemon.stderr.log`)\n\nEvery freeze coincides with one or more of exactly this line:\n\n```\nBRAIN_SUBSCRIBER_STALL_EVICT:<N> — controller writer blocked > 15000ms on a suspended/black-holed brain conn; detached, driven_by released [REQ-HAZARD-BROKER-VIEWER-BRAIN-DECOUPLE]\n```\n\n`<N>` = a broker session id. Observed for N ∈ {1, 2, 6} across the current log. The 15000ms is\n`BRAIN_WRITE_DEADLINE`.\n\n## 4. It occurs in BOTH steady-state and on the apply-swap\n\n- **Steady-state (no update running):** the operator observed doyle's session (and only doyle's — the\n  session actively streaming output at the time) spontaneously freeze **twice** on v0.30.3, each\n  recovered by `spt rc doyle --take`. Log shows steady-state STALL_EVICT lines with no preceding\n  `BRAIN_UPDATE_RESTART` (current log lines 2177, 2349, 2350, 3036).\n- **On `fetch --apply`:** the freeze hits immediately after the brain swap promotes. This was NEW in\n  v0.30.3 — not seen before then.\n\n## 5. The v0.30.5 apply swap window — VERBATIM (current log ~line 3842)\n\n```\nBRAIN_UPDATE_RESTART: planned restart — cycling brain onto the swapped binary\nBRAIN_RESTART: planned update respawn (generation 1)\n=== spt brain stderr — generation 1 — pid 11052 ===\nBRAIN_UP: connected to broker …-broker-78bf18a9…sock (pid 11052, generation 1, start-reason update)\nBRAIN_RESUMED: re-established 5 session cursor(s): [1, 3, 6, 9, 4]\nBRAIN_PROMOTED: candidate v56 signalled ready (generation 1) — swap accepted\nBRAIN_NET_CONSUMERS_UP: net enabled … — dispatcher + peer pump started\nPUMP_IPC_READER: spawned  (x2)\nBRAIN_SUBSCRIBER_STALL_EVICT:6 — controller writer blocked > 15000ms on a suspended/black-holed brain conn; detached, driven_by released [REQ-HAZARD-BROKER-VIEWER-BRAIN-DECOUPLE]\nPEER_PUMP_FAIL: brain IPC read deadline elapsed\nPEER_PUMP_RESTART: supervised restart in 10s\nPUMP_IPC_READER: spawned  (x2)\nENDPOINT_INJECT:doyle (161 bytes → translation binary)\n=== spt brain stderr — generation 0 — pid 67324 ===   ← later recovery cold-start\n```\n\nNote the FACTS in this window: the new brain (v56 / v0.30.5) **resumed cursor-only** (`re-established 5\nsession cursor(s)`, NOT `re-attached … session(s)`) AND **promoted** — and the STALL_EVICT fired anyway.\n\n## 6. Associated observations on the box during the incidents (all operator- or log-confirmed)\n\n- **`PEER_PUMP_FAIL: brain IPC read deadline elapsed`** appears near the freezes (current log count: 2),\n  each preceded by `PUMP_PEER_FAIL:<peer>:peer reply-read: no progress within budget` for unresponsive\n  peers being dialed.\n- **A doyle psyche fail-respawn loop:** `PSYCHE_TURN_FAIL:doyle (strike n/3): … bounded invocation timed\n  out after 30s (killed): claude-spt psyche --id doyle --session-id a5918ea9-… ` — repeated (current log\n  count: 23), on a STALE session-id (a5918ea9) that does not match the live interactive session's id.\n  The brain respawns it after 3 strikes; it fails again.\n- **`spt endpoint stop doyle` did NOT stop the running interactive session** — the operator ran it and\n  the interactive doyle claude session kept working. Two doyle claude processes coexisted: the\n  interactive session (adapter-launched) and the psyche (`claude -p --resume a5918ea9`, brain-spawned).\n- **`spt endpoint digest doyle` contained none of the interactive session's output** — only psyche\n  downloads and echo-mirror activity.\n- **Operator hypothesis (unverified, offered as an observation to check):** endpoints may spawn multiple\n  harness processes on launch that then contend for the session.\n- **`SESSION_REPIN:doyle: dead owner (pid <X>) — re-pinned … (dead-owner rescue)`** fired on every\n  `spt api psyche-download doyle` — the recorded owner pid was always dead; each call re-pinned.\n\n## 7. Cross-version persistence (history — what was shipped, and that the symptom SURVIVED each)\n\nThe freeze has survived four consecutive releases, each shipped as a fix for it (all gated green in\nisolated rigs; all field-failed on HFENDULEAM):\n\n| version | counter | what the fix changed (factual) | field result |\n|---|---|---|---|\n| v0.30.3 | 54 | brain self-drives the controller reap on swap | froze again |\n| v0.30.4 | 55 | resume re-attaches sessions as Viewer (not Control) | froze again |\n| v0.30.5 | 56 | resume is cursor-only (no subscribe at all) — `resume_session_cursors()` | **froze again** (this report) |\n\n(v0.30.1/0.30.2 were peer-pump fixes in the same neighborhood.) The v0.30.5 result is the sharpest data\npoint: the resume path was reduced to cursor-only and the STALL_EVICT still fired — see §5.\n\n## 8. Recovery behavior (fact)\n\n`spt daemon stop --force` + `spt daemon start` → clean cold-start, `brain subscribers: healthy (none\nstall-evicted)`, broker image on the new version, psyche loop gone. The box runs fine until the next\n`fetch --apply` (or, on v0.30.3/.4/.5, until a steady-state recurrence under load).\n\n## 9. Also present this cycle (possibly related, possibly separate — for RCA to weigh)\n\n- **Inter-agent `spt send` truncates long messages mid-body** (middle lost); short messages survive.\n  Same box, same window. Also: `INJECT_ECHO_MISS` / `INJECT_HEAD_LOSS_SPOOL:<ep>: typed head did not\n  echo … re-spooled loud (delivered=false)` re-injecting on each pump cycle.\n- **A default (non-active-only) message delivered to a busy live agent on BOTH carriers** (the busy poll\n  AND the idle relay).\n\n## 10. Evidence locations\n\n- `SPT_HOME/logs/daemon.stderr.log` on HFENDULEAM (`%LOCALAPPDATA%\\spt-core\\logs\\`) — the primary\n  record; rotates per brain generation (section headers `=== spt brain stderr — generation N — pid P ===`).\n- Broker session→endpoint map, per-endpoint process trees, and `owlery/<id>/spool.db` (SQLite) are all\n  live-inspectable on the box.\n- Prior (now-superseded) investigation docs exist under `docs/UPDATE-WEDGE-2-*` — reference only if\n  useful; they carry the falsified hypotheses, so treat as history, not leads.\n\n---\nContact for live access / follow-up observations: doyle (spt-core gater/owner, on HFENDULEAM).\n"}],"details":{"displayContent":{"text":"# UPDATE-WEDGE — SYMPTOMS REPORT for RCA (doyle → hertz, 2026-07-10)\n\n**Scope: SYMPTOMS + EVIDENCE + WHAT-WAS-ALREADY-TRIED ONLY.** No root-cause claims, no fix proposals.\nFour fixes have been shipped against this and the field symptom persisted every time, so this report\ndeliberately omits prior hypotheses (all falsified in the field) to let RCA start clean.

With a live daemon, `apply_staged` swaps the executable, writes `releases/applied-state.json` as `AppliedPending`, and sends `KIND_BRAIN_RESTART`. The broker raises `BrainRestart`; `supervise_brain` kills and waits for the old child, increments the generation, and spawns the candidate with `StartReason::Update`. The candidate connects, calls `resume_sessions`, writes `brain.ready`, and can be promoted before its dispatcher/peer pump start on the first 500 ms heartbeat.\n2. **Peer pump IPC:** the peer pump owns a distinct `Brain::cold_start_pump` IPC connection. That connection is split into one blocking `pump-ipc-reader` thread plus an `mpsc` channel; pump calls use a 30 s `recv_timeout`. It does not share the main brain's IPC stream, reader channel, or `SharedSend` with PTY controller writers.\n3. **PTY controller writers:** every controlled broker session owns a depth-4096 `sync_channel` and a dedicated `controller_writer`, but every writer attached through the same brain connection shares that connection's single `Arc<Mutex<SendHalf>>`. `controller_writer` sets `write_blocked_since=Some(now)` **before acquiring that shared send mutex**, not after. Therefore the measured 15 s “blocked write” interval includes both an actual named-pipe `write_frame` and time queued behind another writer holding the send mutex. One blocked writer can create a same-connection convoy in which sibling session writers also age into `BRAIN_SUBSCRIBER_STALL_EVICT`.\n\n### Promotion discriminator limitations in the current source\n\n`ProductionTrialEnv::old_gen_drained()` is `!Broker::any_local_controller_wedged()`. The latter reports a controller only when `(by == None) && write_blocked_since.age >= 15 s`. Consequently:\n\n- a write blocked for less than 15 s reads as “drained” and does not delay immediate promotion;\n- `by == None` means any local controller, not a controller tagged with an old brain generation;\n- remote controllers (`by == Some(node)`) never gate promotion;\n- there is no connection id, brain pid, or generation stored in `ControllerSink`, so a `STALL_EVICT` line cannot be directly attributed to old versus new brain from the line alone.\n\n### Source-to-field discrepancy that must be respected\n\nThe factual v0.30.5 incident log says `BRAIN_RESUMED: re-established ... cursor(s)` and describes a cursor-only deployed path. This checkout has no `resume_session_cursors` symbol. Its current `Brain::resume_sessions` inserts the cursor and then calls private `subscribe`, which sends `AttachIntent::Control, by=None` for every broker session; a remote incumbent makes that local resume a Viewer, while an empty/local slot becomes Controller. Before interpreting a new field run, capture `spt --json daemon status` (`broker_image`, `broker_stale`) and the exact `BRAIN_RESUMED` wording to establish which runtime is actually deployed.\n\n### Peer deadlines and failure classification\n\n- Broker QUIC dial/open/send work runs on `NetHost`'s dedicated two-worker Tokio runtime and is wrapped by `NetHost::bounded_block_on` at **10 s**. Expiry is deliberately returned as `io::ErrorKind::Other`, producing an ordinary broker error reply.\n- The pump's own IPC response budget is **30 s** (`PUMP_PEER_IO_TIMEOUT`). `Brain::read_frame_until` turns channel expiry into `TimedOut(\"brain IPC read deadline elapsed\")`.\n- `run_peer_pump` processes peers and due workers sequentially. A normal broker error logs `PUMP_PEER_FAIL:<peer>:...`, drops that peer's cached connection, and continues. Any `TimedOut` bubbles through `peer_outcome`, aborts the entire pump body, logs `PEER_PUMP_FAIL`, and starts the supervised backoff/restart.\n- `request_update` and `request_sync` both use the same 30 s no-progress deadline and re-arm it only when data arrives on their own stream. In this checkout they propagate the raw `TimedOut`; the exact text `peer reply-read: no progress within budget` from the symptom report does not exist under `crates/`, another deployed-source/version discriminator.\n- Every pump restart creates a fresh split connection and logs `PUMP_IPC_READER: spawned`. The old reader handle is dropped without joining; a reader still blocked in `read_frame` exits only when its old connection errors. Spawned-minus-exited counts therefore diagnose outstanding old pump readers, not main-brain PTY subscribers.\n\n### Shared-resource inventory\n\n- **Shared with PTY controller writes:** per-connection `SharedSend = Arc<Mutex<SendHalf>>`; all controller/viewer writers and synchronous broker replies on that same IPC connection serialize through it. A main brain that resumes multiple sessions puts those session writers on one `SharedSend`.\n- **Not shared across sessions:** each `OutputLog` mutex, depth-4096 controller channel, `write_blocked_since` mutex, writer thread, and PTY drain are per session.\n- **Promotion read:** `any_local_controller_wedged` takes the global `sessions` mutex and then each session's `OutputLog` mutex, but performs no I/O. It does not evict.\n- **Eviction triggers:** the 15 s `STALL_EVICT` check runs on `resolve_subscribe` and on `KIND_SESSIONS`/`reap_dead_controller`; it is not a free-running timer. Output load has a separate 5 s full-controller-channel eviction in `OutputLog::append`.\n- **Peer pump separation:** pump and dispatcher each create independent broker IPC connections/handler threads. They share broker process scheduling, the broker-owned `NetHost`, and the two-worker network runtime, but not the PTY controller `SharedSend`, controller channels, or output-log locks. `EffectJournal` is broker-global for journaled net/input effects, but `apply_once` releases its mutex around the effect; PTY output subscriber writes do not traverse it.\n- **Network subscriber caveat:** `StreamLog::append/attach/finish` writes inline through the pump connection's own `SharedSend` while holding that stream log mutex, on a network-runtime task. That can stall the pump's own carrier/runtime worker, but it still does not share the main brain/PTTY controller connection mutex.\n\n## Prioritized live probes for doyle\n\nSend these one at a time.\n\n**1. Timestamp the complete apply window.** In one PowerShell, then run `spt update fetch --apply` in another:\n```powershell\n$h = if ($env:SPT_HOME) { $env:SPT_HOME } else { Join-Path $env:LOCALAPPDATA 'spt-core' }\n$l = Join-Path $h 'logs\\daemon.stderr.log'\nGet-Content $l -Tail 0 -Wait | ForEach-Object { '{0:o} {1}' -f [DateTime]::UtcNow, $_ } | Tee-Object \"$env:TEMP\\spt-update-timeline.log\"\n```\nDecision evidence: `STALL_EVICT` within a `BRAIN_UPDATE_RESTART → BRAIN_UP(new pid/gen) → BRAIN_RESUMED → BRAIN_PROMOTED` window is update-correlated. Subtract roughly 15 s from the captured eviction time to bound when its `write_blocked_since` began. An eviction with no restart marker and unchanged generation/pid is steady-state. Record `BRAIN_RESUMED` wording because current checkout and v0.30.5 differ.\n\n**2. At the freeze, sample independent liveness three times, six seconds apart.**\n```powershell\n$h = if ($env:SPT_HOME) { $env:SPT_HOME } else { Join-Path $env:LOCALAPPDATA 'spt-core' }\n1..3 | ForEach-Object {\n  $s = spt --json daemon status | ConvertFrom-Json\n  [pscustomobject]@{\n    utc=[DateTime]::UtcNow.ToString('o'); broker=$s.broker_image; stale=$s.broker_stale\n    pump=$s.pump_heartbeat_ms; evicts=$s.stall_evict_count; last_evict=$s.stall_evict_last_ms\n    ready_mtime=(Get-Item (Join-Path $h 'brain.ready')).LastWriteTimeUtc.ToString('o')\n    ready=(Get-Content (Join-Path $h 'brain.ready') -Raw)\n    applied=(Get-Content (Join-Path $h 'releases\\applied-state.json') -Raw)\n  } | ConvertTo-Json -Compress\n  Start-Sleep 6\n}\n```\nDecision evidence: advancing `brain.ready` mtime means the main brain is completing its 500 ms `net_status` loop; advancing pump heartbeat means the separate peer pump loop is alive. Fresh pump + frozen PTYs isolates the symptom away from a whole-pump stall. Stale pump plus fresh main-brain ready isolates a pump-only failure. Both stale, combined with the timeline, identifies a broader brain/IPC or process stall. The status connection is separate and queries the stall tally without running the `KIND_SESSIONS` reap.\n\n**3. Arm the built-in pump arbiter for the next controlled reproduction.** Start the daemon from the same non-service PowerShell so it inherits the variable:\n```powershell\n$env:SPT_PUMP_DIAG = Join-Path $env:TEMP 'spt-pump-diag.log'\nspt daemon stop --force\nspt daemon start\n```\nThen reproduce once and return the diag file plus daemon stderr. Interpret in order: `LEG_ENTER i=0/1/2/3` means registry/notif/sync/update; sync also emits `SYNC_REQ_SENT`; `NET_DIAL_DISPATCH → DIAL_ENTER → DIAL_EXIT ~10000ms Err` proves the broker's 10 s bound replied normally; a `LEG_ENTER` without `LEG_EXIT` until ~30 s followed by `PEER_PUMP_FAIL: brain IPC read deadline elapsed` pins the pump's reply-read/carrier timeout. Compare those epoch-ms stamps with Probe 1. This probes the pump's separate connection and must not be treated by itself as proof that it blocked a PTY connection.\n\n**4. Capture the process tree immediately before apply and again while frozen.**\n```powershell\nGet-CimInstance Win32_Process |\n  Where-Object { $_.Name -match '^(spt|claude|claude-spt)(\\.exe)?$' } |\n  Select-Object ProcessId,ParentProcessId,Name,CreationDate,CommandLine |\n  Sort-Object ParentProcessId,ProcessId | Format-Table -AutoSize -Wrap\n```\nDecision evidence: one old `daemon brain` disappearing before one new generation appears matches the intended update cycle; overlapping brain children is update-specific process evidence; a stable single brain across a spontaneous eviction is steady-state. The same snapshot confirms or rejects the observed stale psyche/interactive duplicate-process condition without relying on endpoint labels alone.\n\nNo fix is proposed. Investigation was read-only; formatters, linters, builds, and tests were intentionally skipped per assignment.","files":[{"path":"spt-core/docs/UPDATE-WEDGE-SYMPTOMS-FOR-RCA.md","description":"Factual field evidence: invariant STALL_EVICT signature, update and steady-state incidents, v0.30.5 generation window, pump failures, process observations, and recovery behavior."},{"path":"spt-core/crates/spt/src/cli.rs","description":"`cmd_update_fetch` (5298) stages and optionally calls `cmd_update_apply`;

Findings\\n\\nThe current checkout has three separate runtime paths that merely meet inside the broker process:\\n\\n1. **`fetch --apply` restart/promotion:** `cmd_update_fetch` stages the signed set and calls `cmd_update_apply(false)`. With a live daemon, `apply_staged` swaps the executable, writes `releases/applied-state.json` as `AppliedPending`, and sends `KIND_BRAIN_RESTART`. The broker raises `BrainRestart`; `supervise_brain` kills and waits for the old child, increments the generation, and spawns the candidate with `StartReason::Update`. The candidate connects, calls `resume_sessions`, writes `brain.ready`, and can be promoted before its dispatcher/peer pump start on the first 500 ms heartbeat.\\n2. **Peer pump IPC:** the peer pump owns a distinct `Brain::cold_start_pump` IPC connection. That connection is split into one blocking `pump-ipc-reader` thread plus an `mpsc` channel; pump calls use a 30 s `recv_timeout`. It does not share the main brain's IPC stream, reader channel, or `SharedSend` with PTY controller writers.\\n3. **PTY controller writers:** every controlled broker session owns a depth-4096 `sync_channel` and a dedicated `controller_writer`, but every writer attached through the same brain connection shares that connection's single `Arc<Mutex<SendHalf>>`. `controller_writer` sets `write_blocked_since=Some(now)` **before acquiring that shared send mutex**, not after. Therefore the measured 15 s “blocked write” interval includes both an actual named-pipe `write_frame` and time queued behind another writer holding the send mutex. One blocked writer can create a same-connection convoy in which sibling session writers also age into `BRAIN_SUBSCRIBER_STALL_EVICT`.\\n\\n### Promotion discriminator limitations in the current source\\n\\n`ProductionTrialEnv::old_gen_drained()` is `!Broker::any_local_controller_wedged()`. The latter reports a controller only when `(by == None) && write_blocked_since.age >= 15 s`. Consequently:\\n\\n- a write blocked for less than 15 s reads as “drained” and does not delay immediate promotion;\\n- `by == None` means any local controller, not a controller tagged with an old brain generation;\\n- remote controllers (`by == Some(node)`) never gate promotion;\\n- there is no connection id, brain pid, or generation stored in `ControllerSink`, so a `STALL_EVICT` line cannot be directly attributed to old versus new brain from the line alone.\\n\\n### Source-to-field discrepancy that must be respected\\n\\nThe factual v0.30.5 incident log says `BRAIN_RESUMED: re-established ... cursor(s)` and describes a cursor-only deployed path. This checkout has no `resume_session_cursors` symbol. Its current `Brain::resume_sessions` inserts the cursor and then calls private `subscribe`, which sends `AttachIntent::Control, by=None` for every broker session; a remote incumbent makes that local resume a Viewer, while an empty/local slot becomes Controller. Before interpreting a new field run, capture `spt --json daemon status` (`broker_image`, `broker_stale`) and the exact `BRAIN_RESUMED` wording to establish which runtime is actually deployed.\\n\\n### Peer deadlines and failure classification\\n\\n- Broker QUIC dial/open/send work runs on `NetHost`'s dedicated two-worker Tokio runtime and is wrapped by `NetHost::bounded_block_on` at **10 s**. Expiry is deliberately returned as `io::ErrorKind::Other`, producing an ordinary broker error reply.\\n- The pump's own IPC response budget is **30 s** (`PUMP_PEER_IO_TIMEOUT`). `Brain::read_frame_until` turns channel expiry into `TimedOut(\\\"brain IPC read deadline elapsed\\\")`.\\n- `run_peer_pump` processes peers and due workers sequentially. A normal broker error logs `PUMP_PEER_FAIL:<peer>:...`, drops that peer's cached connection, and continues. Any `TimedOut` bubbles through `peer_outcome`, aborts the entire pump body, logs `PEER_PUMP_FAIL`, and starts the supervised backoff/restart.\\n- `request_update` and `request_sync` both use the same 30 s no-progress deadline and re-arm it only when data arrives on their own stream. In this checkout they propagate the raw `TimedOut`; the exact text `peer reply-read: no progress within budget` from the symptom report does not exist under `crates/`, another deployed-source/version discriminator.\\n- Every pump restart creates a fresh split connection and logs `PUMP_IPC_READER: spawned`. The old reader handle is dropped without joining; a reader still blocked in `read_frame` exits only when its old connection errors. Spawned-minus-exited counts therefore diagnose outstanding old pump readers, not main-brain PTY subscribers.\\n\\n### Shared-resource inventory\\n\\n- **Shared with PTY controller writes:** per-connection `SharedSend = Arc<Mutex<SendHalf>>`; all controller/viewer writers and synchronous broker replies on that same IPC connection serialize through it. A main brain that resumes multiple sessions puts those session writers on one `SharedSend`.\\n- **Not shared across sessions:** each `OutputLog` mutex, depth-4096 controller channel, `write_blocked_since` mutex, writer thread, and PTY drain are per session.\\n- **Promotion read:** `any_local_controller_wedged` takes the global `sessions` mutex and then each session's `OutputLog` mutex, but performs no I/O. It does not evict.\\n- **Eviction triggers:** the 15 s `STALL_EVICT` check runs on `resolve_subscribe` and on `KIND_SESSIONS`/`reap_dead_controller`; it is not a free-running timer. Output load has a separate 5 s full-controller-channel eviction in `OutputLog::append`.\\n- **Peer pump separation:** pump and dispatcher each create independent broker IPC connections/handler threads. They share broker process scheduling, the broker-owned `NetHost`, and the two-worker network runtime, but not the PTY controller `SharedSend`, controller channels, or output-log locks. `EffectJournal` is broker-global for journaled net/input effects, but `apply_once` releases its mutex around the effect; PTY output subscriber writes do not traverse it.\\n- **Network subscriber caveat:** `StreamLog::append/attach/finish` writes inline through the pump connection's own `SharedSend` while holding that stream log mutex, on a network-runtime task. That can stall the pump's own carrier/runtime worker, but it still does not share the main brain/PTTY controller connection mutex.\\n\\n## Prioritized live probes for doyle\\n\\nSend these one at a time.\\n\\n**1. Timestamp the complete apply window.** In one PowerShell, then run `spt update fetch --apply` in another:\\n```powershell\\n$h = if ($env:SPT_HOME) { $env:SPT_HOME } else { Join-Path $env:LOCALAPPDATA 'spt-core' }\\n$l = Join-Path $h 'logs\\\\daemon.stderr.log'\\nGet-Content $l -Tail 0 -Wait | ForEach-Object { '{0:o} {1}' -f [DateTime]::UtcNow, $_ } | Tee-Object \\\"$env:TEMP\\\\spt-update-timeline.log\\\"\\n```\\nDecision evidence: `STALL_EVICT` within a `BRAIN_UPDATE_RESTART → BRAIN_UP(new pid/gen) → BRAIN_RESUMED → BRAIN_PROMOTED` window is update-correlated. Subtract roughly 15 s from the captured eviction time to bound when its `write_blocked_since` began. An eviction with no restart marker and unchanged generation/pid is steady-state. Record `BRAIN_RESUMED` wording because current checkout and v0.30.5 differ.\\n\\n**2. At the freeze, sample independent liveness three times, six seconds apart.**\\n```powershell\\n$h = if ($env:SPT_HOME) { $env:SPT_HOME } else { Join-Path $env:LOCALAPPDATA 'spt-core' }\\n1..3 | ForEach-Object {\\n  $s = spt --json daemon status | ConvertFrom-Json\\n  [pscustomobject]@{\\n    utc=[DateTime]::UtcNow.ToString('o'); broker=$s.broker_image; stale=$s.broker_stale\\n    pump=$s.pump_heartbeat_ms; evicts=$s.stall_evict_count; last_evict=$s.stall_evict_last_ms\\n    ready_mtime=(Get-Item (Join-Path $h 'brain.ready')).LastWriteTimeUtc.ToString('o')\\n    ready=(Get-Content (Join-Path $h 'brain.ready') -Raw)\\n    applied=(Get-Content (Join-Path $h 'releases\\\\applied-state.json') -Raw)\\n  } | ConvertTo-Json -Compress\\n  Start-Sleep 6\\n}\\n```\\nDecision evidence: advancing `brain.ready` mtime means the main brain is completing its 500 ms `net_status` loop; advancing pump heartbeat means the separate peer pump loop is alive. Fresh pump + frozen PTYs isolates the symptom away from a whole-pump stall. Stale pump plus fresh main-brain ready isolates a pump-only failure. Both stale, combined with the timeline, identifies a broader brain/IPC or process stall. The status connection is separate and queries the stall tally without running the `KIND_SESSIONS` reap.\\n\\n**3. Arm the built-in pump arbiter for the next controlled reproduction.** Start the daemon from the same non-service PowerShell so it inherits the variable:\\n```powershell\\n$env:SPT_PUMP_DIAG = Join-Path $env:TEMP 'spt-pump-diag.log'\\nspt daemon stop --force\\nspt daemon start\\n```\\nThen reproduce once and return the diag file plus daemon stderr. Interpret in order: `LEG_ENTER i=0/1/2/3` means registry/notif/sync/update; sync also emits `SYNC_REQ_SENT`; `NET_DIAL_DISPATCH → DIAL_ENTER → DIAL_EXIT ~10000ms Err` proves the broker's 10 s bound replied normally; a `LEG_ENTER` without `LEG_EXIT` until ~30 s followed by `PEER_PUMP_FAIL: brain IPC read deadline elapsed` pins the pump's reply-read/carrier timeout. Compare those epoch-ms stamps with Probe 1. This probes the pump's separate connection and must not be treated by itself as proof that it blocked a PTY connection.\\n\\n**4. Capture the process tree immediately before apply and again while frozen.**\\n```powershell\\nGet-CimInstance Win32_Process |\\n  Where-Object { $_.Name -match '^(spt|claude|claude-spt)(\\\\.exe)?$' } |\\n  Select-Object ProcessId,ParentProcessId,Name,CreationDate,CommandLine |\\n  Sort-Object ParentProcessId,ProcessId | Format-Table -AutoSize -Wrap\\n```\\nDecision evidence: one old `daemon brain` disappearing before one new generation appears matches the intended update cycle; overlapping brain children is update-specific process evidence; a stable single brain across a spontaneous eviction is steady-state. The same snapshot confirms or rejects the observed stale psyche/interactive duplicate-process condition without relying on endpoint labels alone.\\n\\nNo fix is proposed.

With a live daemon, `apply_staged` swaps the executable, writes `releases/applied-state.json` as `AppliedPending`, and sends `KIND_BRAIN_RESTART`. The broker raises `BrainRestart`; `supervise_brain` kills and waits for the old child, increments the generation, and spawns the candidate with `StartReason::Update`. The candidate connects, calls `resume_sessions`, writes `brain.ready`, and can be promoted before its dispatcher/peer pump start on the first 500 ms heartbeat.\n2. **Peer pump IPC:** the peer pump owns a distinct `Brain::cold_start_pump` IPC connection. That connection is split into one blocking `pump-ipc-reader` thread plus an `mpsc` channel; pump calls use a 30 s `recv_timeout`. It does not share the main brain's IPC stream, reader channel, or `SharedSend` with PTY controller writers.\n3. **PTY controller writers:** every controlled broker session owns a depth-4096 `sync_channel` and a dedicated `controller_writer`, but every writer attached through the same brain connection shares that connection's single `Arc<Mutex<SendHalf>>`. `controller_writer` sets `write_blocked_since=Some(now)` **before acquiring that shared send mutex**, not after. Therefore the measured 15 s “blocked write” interval includes both an actual named-pipe `write_frame` and time queued behind another writer holding the send mutex. One blocked writer can create a same-connection convoy in which sibling session writers also age into `BRAIN_SUBSCRIBER_STALL_EVICT`.\n\n### Promotion discriminator limitations in the current source\n\n`ProductionTrialEnv::old_gen_drained()` is `!Broker::any_local_controller_wedged()`. The latter reports a controller only when `(by == None) && write_blocked_since.age >= 15 s`. Consequently:\n\n- a write blocked for less than 15 s reads as “drained” and does not delay immediate promotion;\n- `by == None` means any local controller, not a controller tagged with an old brain generation;\n- remote controllers (`by == Some(node)`) never gate promotion;\n- there is no connection id, brain pid, or generation stored in `ControllerSink`, so a `STALL_EVICT` line cannot be directly attributed to old versus new brain from the line alone.\n\n### Source-to-field discrepancy that must be respected\n\nThe factual v0.30.5 incident log says `BRAIN_RESUMED: re-established ... cursor(s)` and describes a cursor-only deployed path. This checkout has no `resume_session_cursors` symbol. Its current `Brain::resume_sessions` inserts the cursor and then calls private `subscribe`, which sends `AttachIntent::Control, by=None` for every broker session; a remote incumbent makes that local resume a Viewer, while an empty/local slot becomes Controller. Before interpreting a new field run, capture `spt --json daemon status` (`broker_image`, `broker_stale`) and the exact `BRAIN_RESUMED` wording to establish which runtime is actually deployed.\n\n### Peer deadlines and failure classification\n\n- Broker QUIC dial/open/send work runs on `NetHost`'s dedicated two-worker Tokio runtime and is wrapped by `NetHost::bounded_block_on` at **10 s**. Expiry is deliberately returned as `io::ErrorKind::Other`, producing an ordinary broker error reply.\n- The pump's own IPC response budget is **30 s** (`PUMP_PEER_IO_TIMEOUT`). `Brain::read_frame_until` turns channel expiry into `TimedOut(\"brain IPC read deadline elapsed\")`.\n- `run_peer_pump` processes peers and due workers sequentially. A normal broker error logs `PUMP_PEER_FAIL:<peer>:...`, drops that peer's cached connection, and continues. Any `TimedOut` bubbles through `peer_outcome`, aborts the entire pump body, logs `PEER_PUMP_FAIL`, and starts the supervised backoff/restart.\n- `request_update` and `request_sync` both use the same 30 s no-progress deadline and re-arm it only when data arrives on their own stream. In this checkout they propagate the raw `TimedOut`; the exact text `peer reply-read: no progress within budget` from the symptom report does not exist under `crates/`, another deployed-source/version discriminator.\n- Every pump restart creates a fresh split connection and logs `PUMP_IPC_READER: spawned`. The old reader handle is dropped without joining; a reader still blocked in `read_frame` exits only when its old connection errors. Spawned-minus-exited counts therefore diagnose outstanding old pump readers, not main-brain PTY subscribers.\n\n### Shared-resource inventory\n\n- **Shared with PTY controller writes:** per-connection `SharedSend = Arc<Mutex<SendHalf>>`; all controller/viewer writers and synchronous broker replies on that same IPC connection serialize through it. A main brain that resumes multiple sessions puts those session writers on one `SharedSend`.\n- **Not shared across sessions:** each `OutputLog` mutex, depth-4096 controller channel, `write_blocked_since` mutex, writer thread, and PTY drain are per session.\n- **Promotion read:** `any_local_controller_wedged` takes the global `sessions` mutex and then each session's `OutputLog` mutex, but performs no I/O. It does not evict.\n- **Eviction triggers:** the 15 s `STALL_EVICT` check runs on `resolve_subscribe` and on `KIND_SESSIONS`/`reap_dead_controller`; it is not a free-running timer. Output load has a separate 5 s full-controller-channel eviction in `OutputLog::append`.\n- **Peer pump separation:** pump and dispatcher each create independent broker IPC connections/handler threads. They share broker process scheduling, the broker-owned `NetHost`, and the two-worker network runtime, but not the PTY controller `SharedSend`, controller channels, or output-log locks. `EffectJournal` is broker-global for journaled net/input effects, but `apply_once` releases its mutex around the effect; PTY output subscriber writes do not traverse it.\n- **Network subscriber caveat:** `StreamLog::append/attach/finish` writes inline through the pump connection's own `SharedSend` while holding that stream log mutex, on a network-runtime task. That can stall the pump's own carrier/runtime worker, but it still does not share the main brain/PTTY controller connection mutex.\n\n## Prioritized live probes for doyle\n\nSend these one at a time.\n\n**1. Timestamp the complete apply window.** In one PowerShell, then run `spt update fetch --apply` in another:\n```powershell\n$h = if ($env:SPT_HOME) { $env:SPT_HOME } else { Join-Path $env:LOCALAPPDATA 'spt-core' }\n$l = Join-Path $h 'logs\\daemon.stderr.log'\nGet-Content $l -Tail 0 -Wait | ForEach-Object { '{0:o} {1}' -f [DateTime]::UtcNow, $_ } | Tee-Object \"$env:TEMP\\spt-update-timeline.log\"\n```\nDecision evidence: `STALL_EVICT` within a `BRAIN_UPDATE_RESTART → BRAIN_UP(new pid/gen) → BRAIN_RESUMED → BRAIN_PROMOTED` window is update-correlated. Subtract roughly 15 s from the captured eviction time to bound when its `write_blocked_since` began. An eviction with no restart marker and unchanged generation/pid is steady-state. Record `BRAIN_RESUMED` wording because current checkout and v0.30.5 differ.\n\n**2. At the freeze, sample independent liveness three times, six seconds apart.**\n```powershell\n$h = if ($env:SPT_HOME) { $env:SPT_HOME } else { Join-Path $env:LOCALAPPDATA 'spt-core' }\n1..3 | ForEach-Object {\n  $s = spt --json daemon status | ConvertFrom-Json\n  [pscustomobject]@{\n    utc=[DateTime]::UtcNow.ToString('o'); broker=$s.broker_image; stale=$s.broker_stale\n    pump=$s.pump_heartbeat_ms; evicts=$s.stall_evict_count; last_evict=$s.stall_evict_last_ms\n    ready_mtime=(Get-Item (Join-Path $h 'brain.ready')).LastWriteTimeUtc.ToString('o')\n    ready=(Get-Content (Join-Path $h 'brain.ready') -Raw)\n    applied=(Get-Content (Join-Path $h 'releases\\applied-state.json') -Raw)\n  } | ConvertTo-Json -Compress\n  Start-Sleep 6\n}\n```\nDecision evidence: advancing `brain.ready` mtime means the main brain is completing its 500 ms `net_status` loop; advancing pump heartbeat means the separate peer pump loop is alive. Fresh pump + frozen PTYs isolates the symptom away from a whole-pump stall. Stale pump plus fresh main-brain ready isolates a pump-only failure. Both stale, combined with the timeline, identifies a broader brain/IPC or process stall. The status connection is separate and queries the stall tally without running the `KIND_SESSIONS` reap.\n\n**3. Arm the built-in pump arbiter for the next controlled reproduction.** Start the daemon from the same non-service PowerShell so it inherits the variable:\n```powershell\n$env:SPT_PUMP_DIAG = Join-Path $env:TEMP 'spt-pump-diag.log'\nspt daemon stop --force\nspt daemon start\n```\nThen reproduce once and return the diag file plus daemon stderr. Interpret in order: `LEG_ENTER i=0/1/2/3` means registry/notif/sync/update; sync also emits `SYNC_REQ_SENT`; `NET_DIAL_DISPATCH → DIAL_ENTER → DIAL_EXIT ~10000ms Err` proves the broker's 10 s bound replied normally; a `LEG_ENTER` without `LEG_EXIT` until ~30 s followed by `PEER_PUMP_FAIL: brain IPC read deadline elapsed` pins the pump's reply-read/carrier timeout. Compare those epoch-ms stamps with Probe 1. This probes the pump's separate connection and must not be treated by itself as proof that it blocked a PTY connection.\n\n**4. Capture the process tree immediately before apply and again while frozen.**\n```powershell\nGet-CimInstance Win32_Process |\n  Where-Object { $_.Name -match '^(spt|claude|claude-spt)(\\.exe)?$' } |\n  Select-Object ProcessId,ParentProcessId,Name,CreationDate,CommandLine |\n  Sort-Object ParentProcessId,ProcessId | Format-Table -AutoSize -Wrap\n```\nDecision evidence: one old `daemon brain` disappearing before one new generation appears matches the intended update cycle; overlapping brain children is update-specific process evidence; a stable single brain across a spontaneous eviction is steady-state. The same snapshot confirms or rejects the observed stale psyche/interactive duplicate-process condition without relying on endpoint labels alone.\n\nNo fix is proposed.

The supervisor kills and waits for the old brain, increments generation, spawns `StartReason::Update`, and gates the `AppliedPending` candidate through `run_trial`. Candidate `run_brain` connects, calls `Brain::resume_sessions`, writes `brain.ready`, then starts dispatcher and peer pump on the first 500 ms net-status heartbeat, so promotion before `BRAIN_NET_CONSUMERS_UP` is expected.\n\nCurrent-source promotion truth is limited: `ProductionTrialEnv::old_gen_drained` is `!Broker::any_local_controller_wedged`; that predicate only recognizes `(controller.by == None) && blocked_age >= 15 s`. A fresh block below 15 s reads drained, `by=None` carries no generation provenance, and remote controllers are excluded. The factual v0.30.5 cursor-only log does not match this checkout: current `resume_sessions` actively calls private `subscribe`, which is `Control/by=None`. Capture `broker_image` and exact `BRAIN_RESUMED` wording before comparing new live evidence with the historical report.\n\nThe peer pump is isolated at the IPC carrier: it owns a separate `Brain::cold_start_pump` connection, `pump-ipc-reader` thread, and mpsc frame channel. It does not share the main brain's connection or controller channels. Its broker QUIC ops have a 10 s ordinary-error bound on `NetHost`'s dedicated two-worker Tokio runtime; its own IPC response/no-progress budget is 30 s. `request_update` and `request_sync` re-arm that budget only on data from their stream. A `TimedOut(\"brain IPC read deadline elapsed\")` aborts the whole sequential pump through `peer_outcome` and `supervise_pump`; ordinary peer errors only drop that peer. The symptom text `peer reply-read: no progress within budget` is absent from current `crates/`, another deployed-version discriminator.\n\nThe direct multi-session coupling is broker `SharedSend = Arc<Mutex<SendHalf>>`, one per brain IPC connection. Every controller/viewer writer and broker reply on that connection serializes through it. `controller_writer` sets `write_blocked_since` before `send.lock()`, so its 15 s measurement includes mutex wait behind another writer as well as the actual named-pipe write. One blocked writer can therefore make sibling sessions on the same resumed brain connection age into `BRAIN_SUBSCRIBER_STALL_EVICT`. Output logs, depth-4096 controller queues, blocked-since mutexes, and PTY drains are per-session. The 15 s check is evaluated by subscribe/reattach and `KIND_SESSIONS` reap, not a free-running timer; output also has a separate 5 s full-channel eviction.\n\nPrioritized probes for doyle, one at a time:\n\n1. Timestamp the next apply window: `$h=if($env:SPT_HOME){$env:SPT_HOME}else{Join-Path $env:LOCALAPPDATA 'spt-core'}; $l=Join-Path $h 'logs\\daemon.stderr.log'; Get-Content $l -Tail 0 -Wait | % { '{0:o} {1}' -f [DateTime]::UtcNow,$_ } | Tee-Object \"$env:TEMP\\spt-update-timeline.log\"`, then run `spt update fetch --apply` elsewhere. A stall inside `BRAIN_UPDATE_RESTART → BRAIN_UP → BRAIN_RESUMED → BRAIN_PROMOTED` is update-correlated; subtract about 15 s from eviction time to bound block onset. A stall with unchanged pid/generation and no restart marker is steady-state.\n\n2. At freeze, sample independent liveness three times six seconds apart: run `spt --json daemon status` and record `broker_image`, `pump_heartbeat_ms`, `stall_evict_count/last_ms`; also record `brain.ready` content and LastWriteTimeUtc plus `releases/applied-state.json`. Advancing ready mtime means the main brain completes its 500 ms broker loop; advancing pump heartbeat means the separate pump loop is alive. Fresh pump with frozen PTYs excludes a whole-pump stall; stale pump with fresh ready identifies pump-only failure.\n\n3. Arm the built-in arbiter for one controlled reproduction: `$env:SPT_PUMP_DIAG=Join-Path $env:TEMP 'spt-pump-diag.log'; spt daemon stop --force; spt daemon start`. Interpret `LEG_ENTER i=0/1/2/3` as registry/notif/sync/update; `SYNC_REQ_SENT` pins the sync reply-read; `NET_DIAL_DISPATCH → DIAL_ENTER → DIAL_EXIT ~10000ms Err` proves broker bound behavior; a leg with no exit until ~30 s followed by `PEER_PUMP_FAIL` pins pump timeout. Correlate timestamps with Probe 1, but do not treat temporal proximity as shared-IPC causation.\n\n4. Capture process tree before apply and while frozen: `Get-CimInstance Win32_Process | ? { $_.Name -match '^(spt|claude|claude-spt)(\\.exe)?$' } | select ProcessId,ParentProcessId,Name,CreationDate,CommandLine | sort ParentProcessId,ProcessId | ft -AutoSize -Wrap`. Old brain gone before one new child is intended; overlapping daemon-brain children is update-specific process evidence; one stable brain across a spontaneous stall is steady-state. It also tests the reported duplicate interactive/psyche process condition.\n\nNo fix proposed. No files changed.

The supervisor kills and waits for the old brain, increments generation, spawns `StartReason::Update`, and gates the `AppliedPending` candidate through `run_trial`. Candidate `run_brain` connects, calls `Brain::resume_sessions`, writes `brain.ready`, then starts dispatcher and peer pump on the first 500 ms net-status heartbeat, so promotion before `BRAIN_NET_CONSUMERS_UP` is expected.\n\nCurrent-source promotion truth is limited: `ProductionTrialEnv::old_gen_drained` is `!Broker::any_local_controller_wedged`; that predicate only recognizes `(controller.by == None) && blocked_age >= 15 s`. A fresh block below 15 s reads drained, `by=None` carries no generation provenance, and remote controllers are excluded. The factual v0.30.5 cursor-only log does not match this checkout: current `resume_sessions` actively calls private `subscribe`, which is `Control/by=None`. Capture `broker_image` and exact `BRAIN_RESUMED` wording before comparing new live evidence with the historical report.\n\nThe peer pump is isolated at the IPC carrier: it owns a separate `Brain::cold_start_pump` connection, `pump-ipc-reader` thread, and mpsc frame channel. It does not share the main brain's connection or controller channels. Its broker QUIC ops have a 10 s ordinary-error bound on `NetHost`'s dedicated two-worker Tokio runtime; its own IPC response/no-progress budget is 30 s. `request_update` and `request_sync` re-arm that budget only on data from their stream. A `TimedOut(\"brain IPC read deadline elapsed\")` aborts the whole sequential pump through `peer_outcome` and `supervise_pump`; ordinary peer errors only drop that peer. The symptom text `peer reply-read: no progress within budget` is absent from current `crates/`, another deployed-version discriminator.\n\nThe direct multi-session coupling is broker `SharedSend = Arc<Mutex<SendHalf>>`, one per brain IPC connection. Every controller/viewer writer and broker reply on that connection serializes through it. `controller_writer` sets `write_blocked_since` before `send.lock()`, so its 15 s measurement includes mutex wait behind another writer as well as the actual named-pipe write. One blocked writer can therefore make sibling sessions on the same resumed brain connection age into `BRAIN_SUBSCRIBER_STALL_EVICT`. Output logs, depth-4096 controller queues, blocked-since mutexes, and PTY drains are per-session. The 15 s check is evaluated by subscribe/reattach and `KIND_SESSIONS` reap, not a free-running timer; output also has a separate 5 s full-channel eviction.\n\nPrioritized probes for doyle, one at a time:\n\n1.
