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: **Broker Concurrency 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 `SubscriberTrace`. Currently visible peers:\n- `Main` — main (main, 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.

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.

The decisive concurrency fact is that `BRAIN_SUBSCRIBER_STALL_EVICT` does **not** prove an OS pipe/socket write was blocked. In `controller_writer`, `write_blocked_since` is set before acquiring the per-connection `SharedSend = Arc<Mutex<SendHalf>>`; the timestamp remains set through mutex acquisition, JSON serialization, length/body `write_all`, and `flush`. It also remains set if the writer thread is descheduled after marking. Therefore the marker proves only that a controller writer made no observed progress for 15 s in the combined interval `{waiting for another writer on the same connection, executing/blocking in write_frame, scheduler-starved}`. Every output writer and broker reply for one accepted brain connection shares that mutex; one lock-holding named-pipe write can make sibling sessions on that connection independently age past 15 s and emit a multi-session cluster. The peer pump uses a distinct broker IPC connection, so it does not share this `SharedSend`; a coincident pump timeout points to a broker-process/runtime/scheduling or peer-network correlation, not direct contention on the session controller’s send mutex.\n\nThe marker is reached from two places: (1) `OutputLog::resolve_subscribe` before a new control/take subscribe, using inline stamp release; and (2) `KIND_SESSIONS` handling via `OutputLog::reap_dead_controller`, using deferred release followed by `converge_perch_stamps`. The brain-hosted live reconciler opens a fresh connection and calls `Brain::sessions()` at boot and every 5 s, so it is the periodic driver that can emit the marker even for an otherwise idle session. Output-driven controller queue saturation is a separate 5 s path (`append` → `mark_controller_gone`) and does not itself emit this marker.\n\nEviction is logical, not cancellation: the `ControllerSink` is removed and `controlled`/remote `driven_by` are converged false/None, but a writer already stuck in `send.lock()` or `write_frame` owns its own `SharedSend`, receiver, and thread stack and is not interrupted or joined. The hosted `PtySession`, child, input writer, drain, output ring/cursor, translation resources, and broker session row survive. The stale writer exits only if its write eventually returns/fails or its queue later disconnects; while blocked it can continue holding or waiting on the shared send mutex.\n\nUpdate flow in the current source is `apply_staged` → `swap_and_record(AppliedPending)` → `Brain::request_brain_restart` → broker `dispatch_brain_restart`/`BrainRestart::request` → supervisor kills and waits for old brain → increments generation and spawns `StartReason::Update` → `run_brain` calls `Brain::resume_sessions` (currently subscribes every session as a local controller), writes `brain.ready`, then starts net consumers after the first 500 ms `net_status` heartbeat. Promotion is readiness plus `ProductionTrialEnv::old_gen_drained`. Exact caveat: `old_gen_drained` negates `Broker::any_local_controller_wedged`, and that predicate becomes true only after the same 15 s threshold. An in-flight local write younger than 15 s therefore reads as “drained”; also `by=None` identifies any local controller, not a brain generation. This is a source-semantic observation, not a fix proposal.\n\nVersion warning: the factual incident document records v0.30.5 `resume_session_cursors()` cursor-only behavior and `BRAIN_RESUMED: re-established ... cursor(s)`. That symbol/text does not exist in the current tree after alternate broad searches; current `Brain::resume_sessions` re-subscribes and logs `re-attached`. Do not retroactively attribute the v0.30.5 incident to current-tree re-subscription. The marker can originate from any existing spawn/attach controller independently of update resume, as the steady-state evidence already establishes.\n\nPrioritized live evidence probes (diagnostic only; no fix proposed):\n\n1. **Pre-arm a Windows WPR/ETW circular trace across the reproduction** with CPU sampling plus CSwitch/ReadyThread and File/pipe I/O stacks; stop immediately after the marker. Filter to broker PID, old/new brain PIDs from `brain.ready`/`BRAIN_UP`, and the 15 s window. **Question:** was the marked broker writer (a) blocked in `NtWriteFile`/named-pipe `SendHalf::write` or flush, (b) sleeping on Rust/Windows mutex acquisition behind another broker writer, or (c) runnable/ready but not scheduled? A pending write stack and sleeping wait state discriminate pipe backpressure; long ReadyTime with no execution discriminates scheduler starvation. This is the strongest direct discriminator because current Rust state conflates all three.\n\n2. **Capture three closely spaced full dumps of both broker and brain around the first marker** (event-trigger from the stderr tail; e.g. immediately, +100–250 ms, +1 s; retain matching PDBs). Inspect every broker thread, not only the session named in the marker. **Question:** is there one controller writer holding the shared `SendHalf` inside `write_frame` while sibling controller writers and the connection handler wait on the same mutex, or are all candidate writers runnable/descheduled? Repeated dumps establish persistence rather than a transient sample. Correlate a blocked owner plus sibling mutex waiters with clustered session IDs; inspect the brain side for its corresponding pipe reader and whether it is asleep, CPU-bound, or blocked elsewhere.\n\n3. **Use a diagnostic build that splits the existing one timestamp into observable phases at `broker.rs::controller_writer`**: connection identity (`Arc::as_ptr(&SharedSend)` or a broker-minted conn id), sid, epoch, OS TID, `WAIT_SEND_LOCK` timestamp immediately before `send.lock`, `WRITE_FRAME` timestamp immediately after lock acquisition, and `WRITE_OK/ERR` with seq/bytes. Have the existing eviction watchdog print the sampled phase and age; do not change deadlines or ownership. **Question:** which portion of the current 15 s aggregate interval is actually aging, and do multiple evicted sessions share one connection/lock owner? This directly removes the marker’s present ambiguity between mutex wait and codec/pipe write. ETW from probe 1 remains necessary to distinguish a phase-stuck-but-descheduled thread from an executing wait.\n\n4. **Enable the already-built `SPT_PUMP_DIAG=<world-writable path>` capture and sample `identity/pump-heartbeat.json` through the same update window.** Use `LEG_ENTER/LEG_EXIT`, `NET_DIAL_DISPATCH`, `DIAL_ENTER/DIAL_EXIT`, `SYNC_REQ_SENT`, `PUMP_IPC_READER`, `PUMP_PEER_FAIL`, and `PEER_PUMP_FAIL/RESTART`. **Question:** is the nearby pump failure an independent peer/QUIC wait, a missing broker dispatch/reply on the pump’s separate IPC connection, or broad scheduling loss? `DIAL_ENTER`→`DIAL_EXIT ~10s Err` is the broker QUIC bound working; `LEG_ENTER` with no exit until 30 s and no dispatch marker is a pump IPC reply starvation; a stale pump heartbeat plus broker-wide ReadyTime supports scheduler starvation. Because the pump connection is separate, this probe is correlation evidence, not proof of controller-pipe blockage.\n\n5. **Take a high-cadence state timeline (100–250 ms around apply, slower outside it)** of `brain.ready` `{pid,generation,exe_hash}`, `spt daemon status` stall count/last time, `identity/pump-heartbeat.json`, per-endpoint `info.json` fields `controlled`, `driven_by`, `viewer_count`, and broker session `resume_seq/controller_by` via `Brain::sessions`; retain stderr generation markers. **Question:** did promotion precede the writer crossing 15 s, did logical release actually converge for every named session, did cursor progress stop before eviction, and was pump/main-brain liveness advancing concurrently? This establishes ordering and blast radius but cannot by itself distinguish mutex/pipe wait from scheduler starvation.\n\nExisting runtime state is insufficient for the central distinction: `write_blocked_since` is private and phase-conflated; `_writer.is_finished` only distinguishes exited vs still-live; `last_ok` is channel handoff time, not socket progress; `delivered_through` is a successful-write cursor without a progress timestamp; stall counters are post-event only; controller writer threads are unnamed; and no connection id/TID/lock-owner is surfaced. One useful negative inference is that marker emission itself proves some broker handler/reconcile thread was scheduled and acquired the sessions/log/blocked-state locks at that instant, though it says nothing about whether the target writer received CPU during the prior 15 s.","files":[{"path":"spt-core/docs/UPDATE-WEDGE-SYMPTOMS-FOR-RCA.md","description":"Factual field evidence: invariant marker, steady-state and apply-swap occurrence, v0.30.5 cursor-only resume, promotion ordering, pump failures, multi-session HFENDULEAM population.

Each output log owns one logical controller sink and many viewer sinks. Controller/viewer writer threads perform blocking IPC writes off the PTY drain. The important exception to per-session isolation is `SharedSend`: it is created once in `Broker::handle_conn` after splitting an accepted connection and cloned into every session role held by that brain connection, plus broker ack/error paths. Thus sessions subscribed through the same brain are coupled at the send mutex and named-pipe buffer.\n\nA connection handler tracks `my_subs`; receive EOF invokes `detach_if` for those session IDs, but only clears a role if its `SharedSend` pointer is still current. Sessions persist across the connection loss. `clear_controller` drops the sink and stamps the endpoint; it cannot forcibly cancel a thread already blocked because the thread owns cloned resources. Reattachment creates a new controller writer and advances `controller_epoch`; the epoch gate suppresses stale **initial replay** writes after they acquire the mutex, but the old live-path writer has no epoch gate and a currently blocked call cannot observe the bump until it returns.\n\nThe peer pump is process-shared but connection-isolated: `spawn_net_consumers` creates dispatcher and pump clients independently of the main brain and each other. The pump’s `BrainConn::Split` owns its own send half and a named `pump-ipc-reader`; its 30 s timeout is channel-side. On the broker, accepted connections each get their own handler thread and their own `SharedSend`.

complete. The decisive concurrency fact is that `BRAIN_SUBSCRIBER_STALL_EVICT` does **not** prove an OS pipe/socket write was blocked. In `controller_writer`, `write_blocked_since` is set before acquiring the per-connection `SharedSend = Arc<Mutex<SendHalf>>`; the timestamp remains set through mutex acquisition, JSON serialization, length/body `write_all`, and `flush`. It also remains set if the writer thread is descheduled after marking. Therefore the marker proves only that a controller writer made no observed progress for 15 s in the combined interval `{waiting for another writer on the same connection, executing/blocking in write_frame, scheduler-starved}`. Every output writer and broker reply for one accepted brain connection shares that mutex; one lock-holding named-pipe write can make sibling sessions on that connection independently age past 15 s and emit a multi-session cluster. The peer pump uses a distinct broker IPC connection, so it does not share this `SharedSend`; a coincident pump timeout points to a broker-process/runtime/scheduling or peer-network correlation, not direct contention on the session controller’s send mutex.\\n\\nThe marker is reached from two places: (1) `OutputLog::resolve_subscribe` before a new control/take subscribe, using inline stamp release; and (2) `KIND_SESSIONS` handling via `OutputLog::reap_dead_controller`, using deferred release followed by `converge_perch_stamps`. The brain-hosted live reconciler opens a fresh connection and calls `Brain::sessions()` at boot and every 5 s, so it is the periodic driver that can emit the marker even for an otherwise idle session. Output-driven controller queue saturation is a separate 5 s path (`append` → `mark_controller_gone`) and does not itself emit this marker.\\n\\nEviction is logical, not cancellation: the `ControllerSink` is removed and `controlled`/remote `driven_by` are converged false/None, but a writer already stuck in `send.lock()` or `write_frame` owns its own `SharedSend`, receiver, and thread stack and is not interrupted or joined. The hosted `PtySession`, child, input writer, drain, output ring/cursor, translation resources, and broker session row survive. The stale writer exits only if its write eventually returns/fails or its queue later disconnects; while blocked it can continue holding or waiting on the shared send mutex.\\n\\nUpdate flow in the current source is `apply_staged` → `swap_and_record(AppliedPending)` → `Brain::request_brain_restart` → broker `dispatch_brain_restart`/`BrainRestart::request` → supervisor kills and waits for old brain → increments generation and spawns `StartReason::Update` → `run_brain` calls `Brain::resume_sessions` (currently subscribes every session as a local controller), writes `brain.ready`, then starts net consumers after the first 500 ms `net_status` heartbeat. Promotion is readiness plus `ProductionTrialEnv::old_gen_drained`. Exact caveat: `old_gen_drained` negates `Broker::any_local_controller_wedged`, and that predicate becomes true only after the same 15 s threshold. An in-flight local write younger than 15 s therefore reads as “drained”; also `by=None` identifies any local controller, not a brain generation. This is a source-semantic observation, not a fix proposal.\\n\\nVersion warning: the factual incident document records v0.30.5 `resume_session_cursors()` cursor-only behavior and `BRAIN_RESUMED: re-established ... cursor(s)`. That symbol/text does not exist in the current tree after alternate broad searches; current `Brain::resume_sessions` re-subscribes and logs `re-attached`. Do not retroactively attribute the v0.30.5 incident to current-tree re-subscription. The marker can originate from any existing spawn/attach controller independently of update resume, as the steady-state evidence already establishes.\\n\\nPrioritized live evidence probes (diagnostic only; no fix proposed):\\n\\n1. **Pre-arm a Windows WPR/ETW circular trace across the reproduction** with CPU sampling plus CSwitch/ReadyThread and File/pipe I/O stacks; stop immediately after the marker. Filter to broker PID, old/new brain PIDs from `brain.ready`/`BRAIN_UP`, and the 15 s window. **Question:** was the marked broker writer (a) blocked in `NtWriteFile`/named-pipe `SendHalf::write` or flush, (b) sleeping on Rust/Windows mutex acquisition behind another broker writer, or (c) runnable/ready but not scheduled? A pending write stack and sleeping wait state discriminate pipe backpressure; long ReadyTime with no execution discriminates scheduler starvation. This is the strongest direct discriminator because current Rust state conflates all three.\\n\\n2. **Capture three closely spaced full dumps of both broker and brain around the first marker** (event-trigger from the stderr tail; e.g. immediately, +100–250 ms, +1 s; retain matching PDBs). Inspect every broker thread, not only the session named in the marker. **Question:** is there one controller writer holding the shared `SendHalf` inside `write_frame` while sibling controller writers and the connection handler wait on the same mutex, or are all candidate writers runnable/descheduled? Repeated dumps establish persistence rather than a transient sample. Correlate a blocked owner plus sibling mutex waiters with clustered session IDs; inspect the brain side for its corresponding pipe reader and whether it is asleep, CPU-bound, or blocked elsewhere.\\n\\n3. **Use a diagnostic build that splits the existing one timestamp into observable phases at `broker.rs::controller_writer`**: connection identity (`Arc::as_ptr(&SharedSend)` or a broker-minted conn id), sid, epoch, OS TID, `WAIT_SEND_LOCK` timestamp immediately before `send.lock`, `WRITE_FRAME` timestamp immediately after lock acquisition, and `WRITE_OK/ERR` with seq/bytes. Have the existing eviction watchdog print the sampled phase and age; do not change deadlines or ownership. **Question:** which portion of the current 15 s aggregate interval is actually aging, and do multiple evicted sessions share one connection/lock owner? This directly removes the marker’s present ambiguity between mutex wait and codec/pipe write. ETW from probe 1 remains necessary to distinguish a phase-stuck-but-descheduled thread from an executing wait.\\n\\n4. **Enable the already-built `SPT_PUMP_DIAG=<world-writable path>` capture and sample `identity/pump-heartbeat.json` through the same update window.** Use `LEG_ENTER/LEG_EXIT`, `NET_DIAL_DISPATCH`, `DIAL_ENTER/DIAL_EXIT`, `SYNC_REQ_SENT`, `PUMP_IPC_READER`, `PUMP_PEER_FAIL`, and `PEER_PUMP_FAIL/RESTART`. **Question:** is the nearby pump failure an independent peer/QUIC wait, a missing broker dispatch/reply on the pump’s separate IPC connection, or broad scheduling loss? `DIAL_ENTER`→`DIAL_EXIT ~10s Err` is the broker QUIC bound working; `LEG_ENTER` with no exit until 30 s and no dispatch marker is a pump IPC reply starvation; a stale pump heartbeat plus broker-wide ReadyTime supports scheduler starvation. Because the pump connection is separate, this probe is correlation evidence, not proof of controller-pipe blockage.\\n\\n5. **Take a high-cadence state timeline (100–250 ms around apply, slower outside it)** of `brain.ready` `{pid,generation,exe_hash}`, `spt daemon status` stall count/last time, `identity/pump-heartbeat.json`, per-endpoint `info.json` fields `controlled`, `driven_by`, `viewer_count`, and broker session `resume_seq/controller_by` via `Brain::sessions`; retain stderr generation markers. **Question:** did promotion precede the writer crossing 15 s, did logical release actually converge for every named session, did cursor progress stop before eviction, and was pump/main-brain liveness advancing concurrently? This establishes ordering and blast radius but cannot by itself distinguish mutex/pipe wait from scheduler starvation.\\n\\nExisting runtime state is insufficient for the central distinction: `write_blocked_since` is private and phase-conflated; `_writer.is_finished` only distinguishes exited vs still-live; `last_ok` is channel handoff time, not socket progress; `delivered_through` is a successful-write cursor without a progress timestamp; stall counters are post-event only; controller writer threads are unnamed; and no connection id/TID/lock-owner is surfaced. One useful negative inference is that marker emission itself proves some broker handler/reconcile thread was scheduled and acquired the sessions/log/blocked-state locks at that instant, though it says nothing about whether the target writer received CPU during the prior 15 s.\",\"files\":[{\"path\":\"spt-core/docs/UPDATE-WEDGE-SYMPTOMS-FOR-RCA.md\",\"description\":\"Factual field evidence: invariant marker, steady-state and apply-swap occurrence, v0.30.5 cursor-only resume, promotion ordering, pump failures, multi-session HFENDULEAM population.

Each output log owns one logical controller sink and many viewer sinks. Controller/viewer writer threads perform blocking IPC writes off the PTY drain. The important exception to per-session isolation is `SharedSend`: it is created once in `Broker::handle_conn` after splitting an accepted connection and cloned into every session role held by that brain connection, plus broker ack/error paths. Thus sessions subscribed through the same brain are coupled at the send mutex and named-pipe buffer.\\n\\nA connection handler tracks `my_subs`; receive EOF invokes `detach_if` for those session IDs, but only clears a role if its `SharedSend` pointer is still current. Sessions persist across the connection loss. `clear_controller` drops the sink and stamps the endpoint; it cannot forcibly cancel a thread already blocked because the thread owns cloned resources. Reattachment creates a new controller writer and advances `controller_epoch`; the epoch gate suppresses stale **initial replay** writes after they acquire the mutex, but the old live-path writer has no epoch gate and a currently blocked call cannot observe the bump until it returns.\\n\\nThe peer pump is process-shared but connection-isolated: `spawn_net_consumers` creates dispatcher and pump clients independently of the main brain and each other. The pump’s `BrainConn::Split` owns its own send half and a named `pump-ipc-reader`; its 30 s timeout is channel-side. On the broker, accepted connections each get their own handler thread and their own `SharedSend`. Pump and session writers can still correlate through OS scheduling, broker process CPU, the shared broker `NetHost`/Tokio runtime, and selected global locks/effect state, but they do not contend on the same controller send mutex merely by existing in the same daemon.\"}}}","call_id":"call_qNyPJ0aa0ev0XIJZIvui6Wcj","name":"yield"}]},"duration":122369.52270000009,"ttft":1209.473900000099,"contextSnapshot":{"promptTokens":170433,"nonMessageTokens":18119}}}

The peer pump uses a distinct broker IPC connection, so it does not share this `SharedSend`; a coincident pump timeout points to a broker-process/runtime/scheduling or peer-network correlation, not direct contention on the session controller’s send mutex.\n\nThe marker is reached from two places: (1) `OutputLog::resolve_subscribe` before a new control/take subscribe, using inline stamp release; and (2) `KIND_SESSIONS` handling via `OutputLog::reap_dead_controller`, using deferred release followed by `converge_perch_stamps`. The brain-hosted live reconciler opens a fresh connection and calls `Brain::sessions()` at boot and every 5 s, so it is the periodic driver that can emit the marker even for an otherwise idle session. Output-driven controller queue saturation is a separate 5 s path (`append` → `mark_controller_gone`) and does not itself emit this marker.\n\nEviction is logical, not cancellation: the `ControllerSink` is removed and `controlled`/remote `driven_by` are converged false/None, but a writer already stuck in `send.lock()` or `write_frame` owns its own `SharedSend`, receiver, and thread stack and is not interrupted or joined. The hosted `PtySession`, child, input writer, drain, output ring/cursor, translation resources, and broker session row survive. The stale writer exits only if its write eventually returns/fails or its queue later disconnects; while blocked it can continue holding or waiting on the shared send mutex.\n\nUpdate flow in the current source is `apply_staged` → `swap_and_record(AppliedPending)` → `Brain::request_brain_restart` → broker `dispatch_brain_restart`/`BrainRestart::request` → supervisor kills and waits for old brain → increments generation and spawns `StartReason::Update` → `run_brain` calls `Brain::resume_sessions` (currently subscribes every session as a local controller), writes `brain.ready`, then starts net consumers after the first 500 ms `net_status` heartbeat. Promotion is readiness plus `ProductionTrialEnv::old_gen_drained`. Exact caveat: `old_gen_drained` negates `Broker::any_local_controller_wedged`, and that predicate becomes true only after the same 15 s threshold. An in-flight local write younger than 15 s therefore reads as “drained”; also `by=None` identifies any local controller, not a brain generation. This is a source-semantic observation, not a fix proposal.\n\nVersion warning: the factual incident document records v0.30.5 `resume_session_cursors()` cursor-only behavior and `BRAIN_RESUMED: re-established ... cursor(s)`. That symbol/text does not exist in the current tree after alternate broad searches; current `Brain::resume_sessions` re-subscribes and logs `re-attached`. Do not retroactively attribute the v0.30.5 incident to current-tree re-subscription. The marker can originate from any existing spawn/attach controller independently of update resume, as the steady-state evidence already establishes.\n\nPrioritized live evidence probes (diagnostic only; no fix proposed):\n\n1. **Pre-arm a Windows WPR/ETW circular trace across the reproduction** with CPU sampling plus CSwitch/ReadyThread and File/pipe I/O stacks; stop immediately after the marker. Filter to broker PID, old/new brain PIDs from `brain.ready`/`BRAIN_UP`, and the 15 s window. **Question:** was the marked broker writer (a) blocked in `NtWriteFile`/named-pipe `SendHalf::write` or flush, (b) sleeping on Rust/Windows mutex acquisition behind another broker writer, or (c) runnable/ready but not scheduled? A pending write stack and sleeping wait state discriminate pipe backpressure; long ReadyTime with no execution discriminates scheduler starvation. This is the strongest direct discriminator because current Rust state conflates all three.\n\n2. **Capture three closely spaced full dumps of both broker and brain around the first marker** (event-trigger from the stderr tail; e.g. immediately, +100–250 ms, +1 s; retain matching PDBs). Inspect every broker thread, not only the session named in the marker. **Question:** is there one controller writer holding the shared `SendHalf` inside `write_frame` while sibling controller writers and the connection handler wait on the same mutex, or are all candidate writers runnable/descheduled? Repeated dumps establish persistence rather than a transient sample. Correlate a blocked owner plus sibling mutex waiters with clustered session IDs; inspect the brain side for its corresponding pipe reader and whether it is asleep, CPU-bound, or blocked elsewhere.\n\n3. **Use a diagnostic build that splits the existing one timestamp into observable phases at `broker.rs::controller_writer`**: connection identity (`Arc::as_ptr(&SharedSend)` or a broker-minted conn id), sid, epoch, OS TID, `WAIT_SEND_LOCK` timestamp immediately before `send.lock`, `WRITE_FRAME` timestamp immediately after lock acquisition, and `WRITE_OK/ERR` with seq/bytes. Have the existing eviction watchdog print the sampled phase and age; do not change deadlines or ownership. **Question:** which portion of the current 15 s aggregate interval is actually aging, and do multiple evicted sessions share one connection/lock owner? This directly removes the marker’s present ambiguity between mutex wait and codec/pipe write. ETW from probe 1 remains necessary to distinguish a phase-stuck-but-descheduled thread from an executing wait.\n\n4. **Enable the already-built `SPT_PUMP_DIAG=<world-writable path>` capture and sample `identity/pump-heartbeat.json` through the same update window.** Use `LEG_ENTER/LEG_EXIT`, `NET_DIAL_DISPATCH`, `DIAL_ENTER/DIAL_EXIT`, `SYNC_REQ_SENT`, `PUMP_IPC_READER`, `PUMP_PEER_FAIL`, and `PEER_PUMP_FAIL/RESTART`. **Question:** is the nearby pump failure an independent peer/QUIC wait, a missing broker dispatch/reply on the pump’s separate IPC connection, or broad scheduling loss? `DIAL_ENTER`→`DIAL_EXIT ~10s Err` is the broker QUIC bound working; `LEG_ENTER` with no exit until 30 s and no dispatch marker is a pump IPC reply starvation; a stale pump heartbeat plus broker-wide ReadyTime supports scheduler starvation. Because the pump connection is separate, this probe is correlation evidence, not proof of controller-pipe blockage.\n\n5. **Take a high-cadence state timeline (100–250 ms around apply, slower outside it)** of `brain.ready` `{pid,generation,exe_hash}`, `spt daemon status` stall count/last time, `identity/pump-heartbeat.json`, per-endpoint `info.json` fields `controlled`, `driven_by`, `viewer_count`, and broker session `resume_seq/controller_by` via `Brain::sessions`; retain stderr generation markers. **Question:** did promotion precede the writer crossing 15 s, did logical release actually converge for every named session, did cursor progress stop before eviction, and was pump/main-brain liveness advancing concurrently? This establishes ordering and blast radius but cannot by itself distinguish mutex/pipe wait from scheduler starvation.\n\nExisting runtime state is insufficient for the central distinction: `write_blocked_since` is private and phase-conflated; `_writer.is_finished` only distinguishes exited vs still-live; `last_ok` is channel handoff time, not socket progress; `delivered_through` is a successful-write cursor without a progress timestamp; stall counters are post-event only; controller writer threads are unnamed; and no connection id/TID/lock-owner is surfaced. One useful negative inference is that marker emission itself proves some broker handler/reconcile thread was scheduled and acquired the sessions/log/blocked-state locks at that instant, though it says nothing about whether the target writer received CPU during the prior 15 s.","files":[{"path":"spt-core/docs/UPDATE-WEDGE-SYMPTOMS-FOR-RCA.md","description":"Factual field evidence: invariant marker, steady-state and apply-swap occurrence, v0.30.5 cursor-only resume, promotion ordering, pump failures, multi-session HFENDULEAM population.

Each output log owns one logical controller sink and many viewer sinks. Controller/viewer writer threads perform blocking IPC writes off the PTY drain. The important exception to per-session isolation is `SharedSend`: it is created once in `Broker::handle_conn` after splitting an accepted connection and cloned into every session role held by that brain connection, plus broker ack/error paths. Thus sessions subscribed through the same brain are coupled at the send mutex and named-pipe buffer.\n\nA connection handler tracks `my_subs`; receive EOF invokes `detach_if` for those session IDs, but only clears a role if its `SharedSend` pointer is still current. Sessions persist across the connection loss. `clear_controller` drops the sink and stamps the endpoint; it cannot forcibly cancel a thread already blocked because the thread owns cloned resources. Reattachment creates a new controller writer and advances `controller_epoch`; the epoch gate suppresses stale **initial replay** writes after they acquire the mutex, but the old live-path writer has no epoch gate and a currently blocked call cannot observe the bump until it returns.\n\nThe peer pump is process-shared but connection-isolated: `spawn_net_consumers` creates dispatcher and pump clients independently of the main brain and each other. The pump’s `BrainConn::Split` owns its own send half and a named `pump-ipc-reader`; its 30 s timeout is channel-side. On the broker, accepted connections each get their own handler thread and their own `SharedSend`. Pump and session writers can still correlate through OS scheduling, broker process CPU, the shared broker `NetHost`/Tokio runtime, and selected global locks/effect state, but they do not contend on the same controller send mutex merely by existing in the same daemon."},"status":"success"},"isError":false,"timestamp":1783656635975}}

The rc `serve_attach` consumer is dedicated and should drain continuously unless its downstream `wire.net_stream_send` blocks.\n• feasibility: no application-level consumer heartbeat exists on rc attach or controller pipe.

The 40ms is local polling, NOT a wire heartbeat; first-event-only stall bound is 30s and disables forever after any event.\\n• target consumer: `crates/spt-daemon/src/attach.rs::serve_attach` (~235): uses TWO broker conns; `brain` continuously receives session Output, `wire` forwards attach stream. Request calls `Brain::attach_as(..., AttachIntent::Take, Some(origin_node))`; `Subscribed::{Controller,TookControl}` arms input/wake. Output ~514 forwards via `wire.net_stream_send`; Displaced ~463 finishes old stream.\\n• broker take: `crates/spt-daemon/src/broker.rs::OutputLog::resolve_subscribe` (~1260 current): first `stall_evict_controller`; differing remote + Take queues Displaced to old `tx`, then `become_controller` unconditionally. `become_controller` drops logical prior sink, bumps epoch, creates new writer.

Additional consumer anchors sent directly to `FixShape`: `rc.rs::run_attach_inner`/`pump`, `attach.rs::serve_attach`, `broker.rs::OutputLog::resolve_subscribe`/`become_controller`, and `brainproc.rs::supervise_brain`. `rc` polls locally every 40 ms but has no application-level controller heartbeat; its 30 s stall check applies only before the first event. A target-side `serve_attach` continuously drains session output and forwards it over a second broker connection, whereas the supervised main brain drains resumed-session output only opportunistically while waiting for its 500 ms `net_status` reply. Update kill/wait causes broker receive-EOF cleanup by `SharedSend` identity while preserving hosted PTY/ring/cursor resources. The key discriminator remains unchanged: the stall timestamp spans pre-lock wait, frame serialization/write/flush, and possible scheduler descheduling, so ETW scheduling/I/O state or phase-split instrumentation is required to distinguish pipe blocking from starvation.","files":[{"path":"spt-core/crates/spt/src/rc.rs","description":"`run_attach_inner` maps `--take` to an attach that bypasses the friendly busy refusal. `pump` is the operator-side output consumer: 40 ms local read polling, output seq dedup/render, Displaced/Exit termination, and a first-event-only 30 s stall backstop."},{"path":"spt-core/crates/spt-daemon/src/attach.rs","description":"`serve_attach` is the target-side consumer.

Broker controller ownership is logical state in `OutputLog`; its writer holds a cloned per-connection `SharedSend`. A take can replace the logical sink and epoch immediately, but a prior writer already blocked before or inside `write_frame` remains alive until the operation returns. Planned update kills/waits for the brain process; broker-side connection EOF later invokes pointer-identity detach without removing the `HostedSession`. No rc/controller application heartbeat proves drain progress.
