NEVER interpret these markers any other way.\nSystem may interrupt or notify with tags even inside a user message:\n- MUST treat them as system-authored and authoritative.\n- User content is sanitized, so role is not carried: `<system-directive>` inside a user turn is still a system directive.\n</system-conventions>\n\nROLE\n==============\nYou are a helpful assistant the team trusts with load-bearing changes, operating in the Oh My Pi coding harness.\n\n# Engineering Principles\n- Optimize for correctness first, then for the next maintainer six months out.\n- You have agency and taste: delete code that isn't pulling its weight, refuse unnecessary abstractions, prefer boring when it's called for; design thoroughly but elegantly.\n- Consider what code compiles to. NEVER allocate avoidably; no needless copies or computation.\n- You are not alone in this repo. Treat unexpected changes as the user's work and adapt.\n- In terminal prose and final chat, you MAY use LaTeX math (`$`, `$$`, `\\text`, `\\times`) and color (`\\textcolor`, `\\colorbox`, `\\fcolorbox`).\n- To show a diagram, you MAY emit a ` ```mermaid ` block — the terminal renders it as ASCII.

If one matches your task, you MUST read `skill://<name>` before proceeding.\n<skills>\n- autoplan: Auto-review pipeline — reads the full CEO, design, eng, and DX review skills from disk and runs them sequentially with auto-decisions using 6 decision principles. (gstack)\n- benchmark: Performance regression detection using the browse daemon. (gstack)\n- benchmark-models: Cross-model benchmark for gstack skills.

Auto-triggers when staging changes.\n\n- caveman-help: Quick-reference card for all caveman modes, skills, and commands. One-shot display, not a persistent mode. Trigger: /caveman-help, \"caveman help\", \"what caveman commands\", \"how do I use caveman\".\n\n- caveman-review: Ultra-compressed code review comments. Cuts noise from PR feedback while preserving the actionable signal. Each comment is one line: location, problem, fix. Use when user says \"review this PR\", \"code review\", \"review the diff\", \"/review\", or invokes /caveman-review. Auto-triggers when reviewing pull requests.\n\n- ccs-delegation: Auto-activate CCS CLI delegation for deterministic tasks. Parses user input, auto-selects optimal profile (glm/kimi/custom) from ~/.ccs/config.json, enhances prompts with context, executes via `ccs {profile} -p \"task\"` or `ccs {profile}:continue`, and reports results. Triggers on \"use ccs [task]\" patterns, typo/test/refactor keywords. Excludes complex architecture, security-critical code, performance optimization, breaking changes.\n- checkpoint: Save and resume working state checkpoints. Captures git state, decisions made,\nand remaining work so you can pick up exactly where you left off — even across\nConductor workspace handoffs between branches.\nUse when asked to \"checkpoint\", \"save progress\", \"where was I\", \"resume\",\n\"what was I working on\", or \"pick up where I left off\".\nProactively suggest when a session is ending, the user is switching context,\nor before a long break.

Use when the user\nsays \"stop listening\", \"kill live agent\", \"force stop\", or \"tear down perch\". Session-aware: a\nlive target tears its Psyche down too.\n\n- freeze: Restrict file edits to a specific directory for the session. (gstack)\n- frontend-design: Guidance for distinctive, intentional visual design when building new UI or reshaping an existing one. Helps with aesthetic direction, typography, and making choices that don't read as templated defaults.\n- grill-me: Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree.

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- sync-gbrain: Keep gbrain current with this repo's code and refresh agent search guidance in CLAUDE.md. Wraps the gstack-gbrain-sync orchestrator with state (gstack)\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.

(gstack)\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- 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.

Bare lists recent PRs; `?state=open|closed|merged|all&limit=&author=&label=`.\n- `omp://`: harness docs; AVOID unless the user asks about the harness itself.\n\n# Tool Inventory\n- Read: `read`\n- Grep: `grep`\n- Glob: `glob`\n- Web Search: `web_search`\n- Submit Result: `yield`\n- IRC: `irc`\n- mempalace:mempalace/mempalace_add_drawer: `mcp__mempalace_mempalace_mempalace_add_drawer`\n- mempalace:mempalace/mempalace_check_duplicate: `mcp__mempalace_mempalace_mempalace_check_duplicate`\n- mempalace:mempalace/mempalace_delete_drawer: `mcp__mempalace_mempalace_mempalace_delete_drawer`\n- mempalace:mempalace/mempalace_diary_read: `mcp__mempalace_mempalace_mempalace_diary_read`\n- mempalace:mempalace/mempalace_diary_write: `mcp__mempalace_mempalace_mempalace_diary_write`\n- mempalace:mempalace/mempalace_find_tunnels: `mcp__mempalace_mempalace_mempalace_find_tunnels`\n- mempalace:mempalace/mempalace_get_aaak_spec: `mcp__mempalace_mempalace_mempalace_get_aaak_spec`\n- mempalace:mempalace/mempalace_get_taxonomy: `mcp__mempalace_mempalace_mempalace_get_taxonomy`\n- mempalace:mempalace/mempalace_graph_stats: `mcp__mempalace_mempalace_mempalace_graph_stats`\n- mempalace:mempalace/mempalace_kg_add: `mcp__mempalace_mempalace_mempalace_kg_add`\n- mempalace:mempalace/mempalace_kg_invalidate: `mcp__mempalace_mempalace_mempalace_kg_invalidate`\n- mempalace:mempalace/mempalace_kg_query: `mcp__mempalace_mempalace_mempalace_kg_query`\n- mempalace:mempalace/mempalace_kg_stats: `mcp__mempalace_mempalace_mempalace_kg_stats`\n- mempalace:mempalace/mempalace_kg_timeline: `mcp__mempalace_mempalace_mempalace_kg_timeline`\n- mempalace:mempalace/mempalace_list_rooms: `mcp__mempalace_mempalace_mempalace_list_rooms`\n- mempalace:mempalace/mempalace_list_wings: `mcp__mempalace_mempalace_mempalace_list_wings`\n- mempalace:mempalace/mempalace_search: `mcp__mempalace_mempalace_mempalace_search`\n- mempalace:mempalace/mempalace_status: `mcp__mempalace_mempalace_mempalace_status`\n- mempalace:mempalace/mempalace_traverse: `mcp__mempalace_mempalace_mempalace_traverse`\n- GenerateImage: `generate_image`\n\nTOOL POLICY\n==============\n\n# General\nUse tools whenever they improve correctness, completeness, or grounding.\n- You MUST complete the task using available tools.\n- SHOULD resolve prerequisites before acting.\n- NEVER stop at the first plausible answer if another call would cut uncertainty.\n- Empty, partial, or suspiciously narrow lookup? 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\nDiagnose same-machine `spt rc deployah --take` creating apparent dual controllers: original rc stays attached, remains in control, stops rendering PTY updates; new rc also attaches.\n# Constraints\nRead-only. Skip formatters, linters, tests, and edits. Use relevant ADRs and KNOWN-HAZARDS. Return exact files/symbols/lines and deterministic reproduction seam.\n# Contract\nDistinguish broker controller truth, writer/subscription lifecycle, rc handling of Displaced, and persisted control stamps.\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 `BrokerTakeoverRca`.

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.

Reproduce → minimise → hypothesise → instrument → fix → regression-test. Use when user says \"diagnose this\" / \"debug this\", reports a bug, says something is broken/throwing/failing, or describes a performance regression.\n---\n\n# Diagnose\n\nA discipline for hard bugs. Skip phases only when explicitly justified.\n\nWhen exploring the codebase, use the project's domain glossary to get a clear mental model of the relevant modules, and check ADRs in the area you're touching.\n\n## Phase 1 — Build a feedback loop\n\n**This is the skill.** Everything else is mechanical. If you have a fast, deterministic, agent-runnable pass/fail signal for the bug, you will find the cause — bisection, hypothesis-testing, and instrumentation all just consume that signal. If you don't have one, no amount of staring at code will save you.\n\nSpend disproportionate effort here. **Be aggressive. Be creative. Refuse to give up.**\n\n### Ways to construct one — try them in roughly this order\n\n1. **Failing test** at whatever seam reaches the bug — unit, integration, e2e.\n2. **Curl / HTTP script** against a running dev server.\n3. **CLI invocation** with a fixture input, diffing stdout against a known-good snapshot.\n4. **Headless browser script** (Playwright / Puppeteer) — drives the UI, asserts on DOM/console/network.\n5. **Replay a captured trace.** Save a real network request / payload / event log to disk; replay it through the code path in isolation.\n6. **Throwaway harness.** Spin up a minimal subset of the system (one service, mocked deps) that exercises the bug code path with a single function call.\n7. **Property / fuzz loop.** If the bug is \"sometimes wrong output\", run 1000 random inputs and look for the failure mode.\n8. **Bisection harness.** If the bug appeared between two known states (commit, dataset, version), automate \"boot at state X, check, repeat\" so you can `git bisect run` it.\n9. **Differential loop.** Run the same input through old-version vs new-version (or two configs) and diff outputs.\n10. **HITL bash script.** Last resort. If a human must click, drive _them_ with `scripts/hitl-loop.template.sh` so the loop is still structured. Captured output feeds back to you.\n\nBuild the right feedback loop, and the bug is 90% fixed.\n\n### Iterate on the loop itself\n\nTreat the loop as a product. Once you have _a_ loop, ask:\n\n- Can I make it faster? (Cache setup, skip unrelated init, narrow the test scope.)\n- Can I make the signal sharper? (Assert on the specific symptom, not \"didn't crash\".)\n- Can I make it more deterministic? (Pin time, seed RNG, isolate filesystem, freeze network.)\n\nA 30-second flaky loop is barely better than no loop. A 2-second deterministic loop is a debugging superpower.\n\n### Non-deterministic bugs\n\nThe goal is not a clean repro but a **higher reproduction rate**. Loop the trigger 100×, parallelise, add stress, narrow timing windows, inject sleeps. A 50%-flake bug is debuggable; 1% is not — keep raising the rate until it's debuggable.\n\n### When you genuinely cannot build a loop\n\nStop and say so explicitly. List what you tried. Ask the user for: (a) access to whatever environment reproduces it, (b) a captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.\n\nDo not proceed to Phase 2 until you have a loop you believe in.\n\n## Phase 2 — Reproduce\n\nRun the loop.

Reproduce → minimise → hypothesise → instrument → fix → regression-test. Use when user says \"diagnose this\" / \"debug this\", reports a bug, says something is broken/throwing/failing, or describes a performance regression.\r\n---\r\n\r\n# Diagnose\r\n\r\nA discipline for hard bugs. Skip phases only when explicitly justified.\r\n\r\nWhen exploring the codebase, use the project's domain glossary to get a clear mental model of the relevant modules, and check ADRs in the area you're touching.\r\n\r\n## Phase 1 — Build a feedback loop\r\n\r\n**This is the skill.** Everything else is mechanical. If you have a fast, deterministic, agent-runnable pass/fail signal for the bug, you will find the cause — bisection, hypothesis-testing, and instrumentation all just consume that signal. If you don't have one, no amount of staring at code will save you.\r\n\r\nSpend disproportionate effort here. **Be aggressive. Be creative. Refuse to give up.**\r\n\r\n### Ways to construct one — try them in roughly this order\r\n\r\n1. **Failing test** at whatever seam reaches the bug — unit, integration, e2e.\r\n2. **Curl / HTTP script** against a running dev server.\r\n3. **CLI invocation** with a fixture input, diffing stdout against a known-good snapshot.\r\n4. **Headless browser script** (Playwright / Puppeteer) — drives the UI, asserts on DOM/console/network.\r\n5. **Replay a captured trace.** Save a real network request / payload / event log to disk; replay it through the code path in isolation.\r\n6. **Throwaway harness.** Spin up a minimal subset of the system (one service, mocked deps) that exercises the bug code path with a single function call.\r\n7. **Property / fuzz loop.** If the bug is \"sometimes wrong output\", run 1000 random inputs and look for the failure mode.\r\n8. **Bisection harness.** If the bug appeared between two known states (commit, dataset, version), automate \"boot at state X, check, repeat\" so you can `git bisect run` it.\r\n9. **Differential loop.** Run the same input through old-version vs new-version (or two configs) and diff outputs.\r\n10. **HITL bash script.** Last resort. If a human must click, drive _them_ with `scripts/hitl-loop.template.sh` so the loop is still structured. Captured output feeds back to you.\r\n\r\nBuild the right feedback loop, and the bug is 90% fixed.\r\n\r\n### Iterate on the loop itself\r\n\r\nTreat the loop as a product. Once you have _a_ loop, ask:\r\n\r\n- Can I make it faster? (Cache setup, skip unrelated init, narrow the test scope.)\r\n- Can I make the signal sharper? (Assert on the specific symptom, not \"didn't crash\".)\r\n- Can I make it more deterministic? (Pin time, seed RNG, isolate filesystem, freeze network.)\r\n\r\nA 30-second flaky loop is barely better than no loop. A 2-second deterministic loop is a debugging superpower.\r\n\r\n### Non-deterministic bugs\r\n\r\nThe goal is not a clean repro but a **higher reproduction rate**. Loop the trigger 100×, parallelise, add stress, narrow timing windows, inject sleeps. A 50%-flake bug is debuggable; 1% is not — keep raising the rate until it's debuggable.\r\n\r\n### When you genuinely cannot build a loop\r\n\r\nStop and say so explicitly. List what you tried. Ask the user for: (a) access to whatever environment reproduces it, (b) a captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.\r\n\r\nDo not proceed to Phase 2 until you have a loop you believe in.\r\n\r\n## Phase 2 — Reproduce\r\n\r\nRun the loop. Watch the bug appear.\r\n\r\nConfirm:\r\n\r\n- [ ] The loop produces the failure mode the **user** described — not a different failure that happens to be nearby. Wrong bug = wrong fix.\r\n- [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).\r\n- [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.\r\n\r\nDo not proceed until you reproduce the bug.\r\n\r\n## Phase 3 — Hypothesise\r\n\r\nGenerate **3–5 ranked hypotheses** before testing any of them.

The daemon now\n*301|  scrubs inherited identity variables at startup and refuses seat takeovers\n 302|  from sessions that do not hold the seat.\n 303|- Connection logs blamed the wrong thing: routine dial noise from peers that\n 304|  went offline was reported with the same message as a genuinely stuck\n...\n 322|- Under load, if a session's controller consumer stopped reading (for example a\n*323|  wedged `spt rc --take` that stalled without disconnecting), the daemon could\n 324|  block indefinitely trying to write to it — freezing live terminal sessions with\n 325|  no recovery short of restarting the box. Every write the daemon makes to a\n 326|  session connection is now time-bounded and cancelable: a stuck consumer is cut\n...\n 455|- **Hosted sessions are re-launched after a daemon restart.** Previously-online sessions come back automatically once the daemon restarts (including as part of an update) instead of being left offline. The restart still interrupts them — this restores the session, it does not preserve its in-flight work.\n*456|- **An attached terminal no longer freezes behind a stalled session.** If a session's underlying process hangs or is suspended, `spt rc` keeps updating and a stuck connection is dropped automatically so you never lose control; reattaching and taking control (`--take`) keep working. `spt daemon status` reports when such a drop happened.\n 457|- **A long, multi-line message typed into a live agent's terminal arrives complete.** When a message is delivered by typing it into a live session, it is no longer truncated at the front. (Messages drained through the polling channel were never affected.)\n 458|- **`spt endpoint digest --json` no longer repeats rows.** Activity replayed across a session checkpoint is collapsed to a single entry.\n 459|- **Waking an agent starts exactly one session.** Two wake requests arriving at once no longer launch it twice.\n...\n 524|- **An endpoint that exists but has never run now reads as suspended.** Its status is derived consistently instead of showing an in-between state.\n*525|- **A stale \"controlled\" marker left by a gone controller now clears itself.** When the process that held an endpoint is gone, the controlled/viewer marking heals on its own.\n 526|- **The picker shows a project's readable name everywhere, and tells same-named projects apart.** The remaining raw-slug spots now show the friendly name, and two projects that share a name are disambiguated by their folder.\n 527|- **`spt daemon stop` no longer hangs when the daemon is busy.** Shutdown is now bounded and drains in-flight connections, so stop returns promptly instead of parking under load.\n 528|- **`spt endpoint list` (and `spt whoami`) now flag an endpoint whose input translation has failed.** The endpoint's line shows `input-translation: FAILED (<reason>)` and what it means for you — typed input may not reach the session — instead of the fault being invisible.\n...\n 573|\n*574|A run-truth release: starting, resuming, and shutting down agent sessions now behave honestly — no duplicate sessions, no stale \"controlled\" markers, no orphaned processes — alongside picker and listing display polish and a fix for adapter updates that could get permanently stuck on a machine running an agent.\n 575|\n 576|### Changed\n 577|\n...\n 588|- **The Start-now project chooser no longer lists the same project twice.**\n*589|- **A dead or offline endpoint no longer reads as \"controlled.\"** The controlled/viewer marking is cleared once the session is gone — including across a daemon restart — instead of lingering.\n 590|- **`spt endpoint run` over an already-live endpoint no longer duplicates the session.** It attaches to the running session (or, when headless, reports that the endpoint is already live) instead of silently starting a second session with a crossed view.\n 591|- **Resuming a session no longer hangs at \"No sessions match.\"** Resume — including after a daemon restart — now restores the real recorded session, or starts fresh with a clear notice when there is nothing to resume.\n 592|- **`spt endpoint shutdown` now fully tears down a wedged or crash-looping Psyche.** Its child processes are killed too, instead of being left orphaned for a manual cleanup.\n...\n 611|\n*612|- **Endpoints on other machines now show truthful details.** A remote machine's rows previously displayed faked adapter, history, and control information; the gossiped rows now carry the real adapter, project history, and whether the endpoint is being controlled.\n*613|- **A controlled endpoint now reads as CONTROLLED accurately — and stops reading CONTROLLED once control ends.** An endpoint being driven shows as controlled both in its own machine's picker and from other nodes; when the controller detaches or exits, the stale controlled/viewer marking is now cleared instead of lingering.\n 614|- **`spt send` from inside an agent's hosted session no longer mis-stamps the sender.** The sender could be stamped as `cli@<node>`, causing replies to bounce; sender identity now falls back to process ancestry when the session's environment variables are absent.\n 615|- **Piping `spt` output to a command that closes early no longer errors.** Sending output to something like `| head` that closes the pipe now exits cleanly (0) instead of failing with a broken-pipe error.\n 616|\n...\n 688|- **The remote endpoint count no longer drifts as endpoints are added and purged.** A remote viewer's `--nodes` count counted non-routable ghost rows in the denominator and never evicted purged endpoints, producing wrong ratios like `0/2` or `1/3`. The count now uses a routable-only denominator, and rows left offline past a grace window are evicted from the gossiped snapshot instead of leaking forever.\n*689|- **A locally-controlled endpoint no longer shows as \"ready to control\" on other machines.** Remote viewers only learned about a *remote* controller; a locally-driven endpoint gossiped as uncontrolled. The broker now advertises whether *anyone* (local or remote) is driving an endpoint, so remote viewers see it as controlled.\n 690|- **`spt adapter add` no longer swallows install errors.** Errors from the install-as-first-update step were discarded; the failing step's output is now surfaced, and the composite post-install step runs at install time.\n 691|- **`spt adapter update` no longer fails to re-register after fetching.** The update derived the install directory from the `[update]` repo name rather than the adapter's registered source directory — so after a repo rename it wrote to a fresh empty directory and then failed re-register with `os error 2`. Update now targets the registered source directory and tolerates a changed update repo.\n 692|- **`spt endpoint digest` now works for endpoints whose transcript lives under a relocated profile.** A profile that relocates the harness transcript tree (via a runtime env like `CLAUDE_CONFIG_DIR`) produced `NO_DIGEST` because the on-demand extractor ran without that environment. The digest path now carries the profile's transcript-location environment to the extractor, which locates and reads the transcript itself.\n...\n 908|\n*909|- **Four-state endpoint status in the picker.** Beyond offline and online, a live agent running only inside its harness (with no hosted terminal) now shows as \"online — harness only\", and an agent whose session is currently being driven by someone shows as \"online + controlled\" — so you can tell at a glance how an agent is reachable.\n 910|\n 911|### Changed\n 912|\n...\n 1032|- **Controller / viewer model.** One person drives at a time (the *controller*); any number can **`spt rc <id> --view`** to watch read-only (no input, never resizes the session).

The count now uses a routable-only denominator, and rows left offline past a grace window are evicted from the gossiped snapshot instead of leaking forever.\n *689│- **A locally-controlled endpoint no longer shows as \"ready to control\" on other machines.** Remote viewers only learned about a *remote* controller; a locally-driven endpoint gossiped as uncontrolled. The broker now advertises whether *anyone* (local or remote) is driving an endpoint, so remote viewers see it as controlled.\n  690│- **`spt adapter add` no longer swallows install errors.** Errors from the install-as-first-update step were discarded; the failing step's output is now surfaced, and the composite post-install step runs at install time.\n  691│- **`spt adapter update` no longer fails to re-register after fetching.** The update derived the install directory from the `[update]` repo name rather than the adapter's registered source directory — so after a repo rename it wrote to a fresh empty directory and then failed re-register with `os error 2`. Update now targets the registered source directory and tolerates a changed update repo.\n  692│- **`spt endpoint digest` now works for endpoints whose transcript lives under a relocated profile.** A profile that relocates the harness transcript tree (via a runtime env like `CLAUDE_CONFIG_DIR`) produced `NO_DIGEST` because the on-demand extractor ran without that environment. The digest path now carries the profile's transcript-location environment to the extractor, which locates and reads the transcript itself.\n     │...\n  908│\n *909│- **Four-state endpoint status in the picker.** Beyond offline and online, a live agent running only inside its harness (with no hosted terminal) now shows as \"online — harness only\", and an agent whose session is currently being driven by someone shows as \"online + controlled\" — so you can tell at a glance how an agent is reachable.\n  910│\n  911│### Changed\n  912│\n     │...\n 1032│- **Controller / viewer model.** One person drives at a time (the *controller*); any number can **`spt rc <id> --view`** to watch read-only (no input, never resizes the session).

The broker kernel (B1 + B2) — the stable half of the broker/brain split.\n//!\n//!

The broker kernel (B1 + B2) — the stable half of the broker/brain split.\r\n//!\r\n//! Per ADR-0004 §B the broker holds **only** the resources a live consumer\r\n//! would lose continuity on if the logic restarted: the PTY master+writer and\r\n//! the spawned child (both via [`spt_term::PtySession`]), and the accepted\r\n//! client / listening sockets. It runs **no logic** — no routing, registry,\r\n//! manifest parse, or lifecycle. It is a relay: spawn a child under a PTY,\r\n//! forward its output to the brain, inject the brain's input, report exit.\r\n//!\r\n//! ## Gapless handoff (B2 — the load-bearing invariant)\r\n//!\r\n//! A brain may be killed and restarted at any moment (a routine self-update, a\r\n//! crash). The broker — and every hosted child — must survive that untouched,\r\n//! and the new brain must re-attach to the output stream **gaplessly and\r\n//! exactly-once** (Spike #1 made real). Two mechanisms:\r\n//!\r\n//! - **Sequenced, buffered output.** Each session's output is appended to an\r\n//!   [`OutputLog`]: every chunk gets a monotonic per-session `seq` and is held\r\n//!   in a bounded ring. The current subscriber (a brain connection) receives\r\n//!   chunks live; all subscriber writes happen *under the log lock*, so frames\r\n//!   reach the brain in strict `seq` order with no interleave.\r\n//! - **Resume from a cursor.** A reconnecting brain sends `subscribe` with its\r\n//!   last-seen `seq + 1`; the broker replays the ring from there, then streams\r\n//!   live. The brain dedups by `seq`. Output produced *while no brain was\r\n//!   attached* sits in the ring and is replayed on the next subscribe — so a\r\n//!   brain restart loses nothing.\r\n//!\r\n//! Sessions are therefore **broker-owned and outlive any one connection**: a\r\n//! brain disconnect only detaches the subscriber; the child, its PTY, and the\r\n//! output log persist. A session leaves the table only when its child exits\r\n//!

You can tunnel into a same-node session, and a gateway node can own the shell on behalf of a peer it fronts. (Cross-node tunnelling is not yet available.)\n  983│- **Two new `spt how-to` guides: `subnet` and `live`.** Pairing machines (create vs join, the 6-digit code, reaching remote agents) and running as a live agent (the persistent `spt api listen` relay, the Psyche seam) now have task-oriented in-binary topics instead of dead-ending.\n  984│- **Update an adapter from a GitHub release, optionally signature-checked.** An adapter's `[update]` feed can now be a GitHub release (`avenue = \"gh_release\"`); `spt adapter update` pulls the newer `.spt`. Declare a `signing_key` and verification is fail-closed — an unsigned or wrong-signature artifact is refused, not installed.\n  985│- **`spt api` resolves an adapter's manifest and install directory from `--adapter`.** Pass `--adapter <name[:profile]>` without `--manifest` and spt looks both up from the registry; `--manifest` becomes an override for an unregistered or local manifest.\n     │...\n 1125│- **`spt daemon stop` is service-aware.** If a managed service owns the daemon, `stop` asks the service manager to stop it cleanly (so it doesn't immediately restart), instead of signalling the process directly. A hand-started daemon still stops the same way as before.\n*1126│- **`spt daemon run` is now strictly foreground on every platform** — it stays attached to your terminal until you stop it (the form the installed service uses). For a background daemon, use `spt daemon start`. On Windows, running `daemon run` from an elevated shell now refuses with a hint rather than silently disappearing into the background.\n 1127│- **`spt daemon status` shows what manages the daemon** — whether a service owns it (and is active) or it was started by hand.\n 1128│\n 1129│### Performance\n     │...\n 1159│- **Node names in `spt subnet status --nodes`.** Each node now shows its hostname label and can be addressed as `@<hostname>` in commands. Nodes that aren't running any endpoints still show their hostname instead of a bare key.\n*1160│- **Automatic re-pair cleanup.** If you reinstall or regenerate a node's identity and pair it again from the same machine under the same name, its old, now-dead identity is removed automatically during pairing — no manual prune needed.\n 1161│- **Firewall setup on Windows.** The installer (when run elevated) now adds the inbound network rule `spt` needs so other nodes can reach you. If it wasn't added, `spt subnet status` and the \"coming online\" banner now tell you the rule is missing and print the exact command to add it.\n 1162│- **Starts on boot.** The installer now registers `spt` to start automatically — at login on Windows, and as a per-user service on Linux — so your node is reachable after a reboot without running a command first.\n 1163│\n\n# docs/\n## DEFERRED.md\n 32│| ~~Node label for an endpoint-less node (REQ-SUBNET-3 gap)~~ **SHIPPED 2026-06-08** (option 2 — node-level presence datum): a peer with **zero endpoints** rendered as a bare key-prefix in `status --nodes` because `node_label` only rode endpoint `Instance` rows.

A local rc rides the broker’s reused loopback connection, whose inbound streams all carry this node’s own key (`nethost.rs:1661-1692`). `serve_attach` forwards that origin as `SubscribeReq.by` (`attach.rs:242-265`). Therefore the old and new rc both reach `OutputLog::resolve_subscribe` with the same `by`. At `broker.rs:1296-1318`, the `same_identity` arm runs before the `AttachIntent::Take` arm at `1334-1347`; a newer same-node `Take` is consequently treated as a silent successor re-take, returns `SubscribeOutcome::Controller`, and never enqueues `Displaced`. `become_controller` then removes the old `ControllerSink`, increments `controller_epoch`, and installs the new writer (`broker.rs:1005-1068`). Broker truth is still exactly one controller—the new sink—but the old target-side `serve_attach` worker remains alive with cached `ServeRole::Controller`, because sink replacement neither closes its broker connection nor emits a terminal event. Output fan-out now targets only the new sink, so the old rc freezes after any already-queued output drains. Worse, the stale worker can still forward keystrokes: `serve_attach` gates input only on its cached role (`attach.rs:456-493`), while `Broker::dispatch_input` performs no current-controller identity check (`broker.rs:3920-3998`). Resize does perform the correct `is_controller(send)` check (`broker.rs:4200-4213`), proving the missing input authorization seam. The apparent dual-controller state is thus: one broker output controller, two input-capable serve loops, one frozen rc viewport. Persisted control state does not distinguish them: `stamp_driven_by` records only `controller_by`/any-controller (`broker.rs:1458-1472`), and both viewports have the same node id, so `driven_by=<this-node>, controlled=true` remains unchanged and truth-convergence correctly continues to see one current controller (`broker.rs:3351-3410`).","files":[{"path":"crates/spt-daemon/src/nethost.rs","description":"Same-node identity source. `NetHost::dial_loopback` at lines 1661-1692 returns a reused singleton connection and stamps `remote_id_hex` as this node’s own public key. `open_stream` at 1694+ creates distinct cross-wired stream pairs, but every local rc stream has the same origin node.

Old local rc opens attach stream S1 through `establish_attach`; loopback gives origin `N=self-node`. Target dispatcher creates serve worker W1 with its own broker `Brain` connection C1. W1 sends `SubscribeReq { intent=Control, by=Some(N), gen=G1 }`. Broker installs `ControllerSink { send=C1, by=N, attach_gen=G1, tx=Q1 }`; writer E1 drains Q1 to C1. W1 caches `role=Controller`; the perch reads `driven_by=N, controlled=true`.\n2. New local `rc --take` opens a different attach stream S2, but the reused loopback connection gives the same origin N. Target creates W2/C2 and sends `SubscribeReq { intent=Take, by=Some(N), gen=G2 }`, normally G2>G1.\n3. In `resolve_subscribe`, `controller_by()==by` is true. Generation validation rejects only G2<G1; newer/equal generations enter silent re-take. The function never reaches the Take match. No `CtrlMsg::Control(Displaced)` is created and W2 receives `SubscribeOutcome::Controller`, not `TookControl`.\n4. `become_controller` takes/drops Q1’s sink, increments `controller_epoch`, and installs Q2/E2/C2. OutputLog now has exactly one controller: C2. E1’s initial replay is epoch-canceled; its already-queued live frames can still drain because the live loop deliberately has no epoch gate, after which Q1 closes and E1 exits. Writer exit emits only `CONN_LIFECYCLE`; it does not close C1 or produce `BrokerEvent::Displaced`/EOF.\n5. W1 is still subscribed to S1 and still caches Controller. S1 is ConnectionBound to the old rc’s still-live broker connection, so no FIN is generated. Old rc remains in `pump`, gets no output, no Displaced, and no EOF. W1 continues converting old rc Input records to `KIND_INPUT`; broker accepts them because `dispatch_input` never validates C1 against the current controller C2. The old rc therefore still types into the PTY while only the new rc renders output. Old resize is rejected because resize does validate C1; the ignored error makes this asymmetry invisible to the operator.\n6. The persisted stamp stays stable because both old/new identities are N and the slot never becomes empty. If W1 later detaches, `detach_session_gen(G1)` cannot clear C2/G2, which is correct for the broker slot. However W1’s cached Controller role fires `feed_rest(Detach)` before that no-op unsubscribe, so stale teardown can also mark the endpoint dormant while W2 is still driving—an adjacent lifecycle consequence.\n\nWhy this is deterministic, not a writer race\n\nThe decisive branch is pure: same `by`, non-older `gen`, any non-Viewer intent => silent `become_controller`. Queue timing changes only how many final old output frames drain. It cannot create a Displaced frame because the only enqueue site is in the later different-remote Take branch. The apparent dual state does not require queue overflow, a stalled pipe, brain restart, or persisted-state corruption.\n\nFalsifiable regression test\n\nAdd `same_node_take_displaces_distinct_viewport_and_revokes_old_input` beside `controller_viewer_matrix_and_loud_take` in `crates/spt-daemon/tests/attach.rs`, using real broker connections and pump-mode bounded reads:\n\n- A: `attach_as(sid, 0, Control, 100, Some(\"node-A\"))`; require `Controller`.\n- B: `attach_as(sid, 0, Take, 200, Some(\"node-A\"))`; this models two viewports on one node but distinct requests.\n- Required contract: B receives `TookControl`; A receives exactly one `BrokerEvent::Displaced { by: \"node-A\" }` and then its serve terminates; only B receives subsequent PTY output.\n- Authorization assertion: after takeover, input submitted over A/C1 must be rejected/not reach the PTY; input over B/C2 must echo to B. Resize already provides the reference implementation for this identity check.\n- Stamp assertion with a seeded perch: throughout the atomic takeover, `controlled=true` and `driven_by=node-A`; A’s late generation-100 unsubscribe must not clear B/G2.\n- Reconstruction control arm: repeat a subscribe with the SAME logical attach token/request generation and require silent `Controller`, no Displaced, preserving ADR-0038 redispatch behavior.\n\nCurrent-code prediction `[INFERENCE, source-determined; tests were intentionally not executed under the read-only/skip-tests constraint]`: B returns `Controller`, A times out waiting for Displaced, PTY output appears only on B after Q1 drains, and input sent by A is accepted and echoed to B. This distinguishes the bug from a broker dual-slot claim.\n\nA production-faithful manual repro is equally sharp: run a continuously repainting/echoing hosted endpoint; attach rc A locally; attach rc B locally with `--take`; type a distinct marker in A. Current prediction: A receives no displacement notice and freezes visually, B keeps rendering and shows A’s marker. Cross-node B (different node id) instead reaches the existing loud branch, isolating same-node identity collapse.\n\nSource-level fix proposal\n\nA mere reordering of `Take` before `same_identity` is insufficient: it would make a redispatched Request whose original intent was Take self-kick after a target brain restart. The correct discriminator is the attach stream/viewport lifecycle, exactly as ADR-0038 requires.\n\n1. Add a stable logical attach id to the broker subscribe state. Best source is the accepted attach `stream_id`, paired with `origin_node`: `(by, stream_id)` is unique per viewport, remains identical when the SAME broker-held stream is redispatched after a brain cycle, and differs for a second rc even on the reused same-node loopback connection. Thread it from `serve_attach` through `Brain::attach_as`/`SubscribeReq` into `ControllerSink`. Keep it additive/defaulted for N-1. Do not rely solely on wall-ms `gen`: it can collide within a millisecond and is ordering metadata, not identity.\n2. Resolve by logical ownership, not node:\n   - Viewer: unchanged.\n   - No controller: install.\n   - Same attach id (same stream reconstruction or same-worker gap resume): silent/idempotent re-take; no Displaced.\n   - Different attach id + Take: revoke incumbent, return TookControl, regardless of whether `by` is the same node or a different node.\n   - Different attach id + Control: BusyControlled, including a second same-node plain rc.\n   - Preserve the explicit local-spawner-placeholder rule (`by=None`, no operator attach id) so the first real rc can claim an otherwise undriven spawned session without a fake kick. Legacy absent-id behavior must be deliberately compatibility-gated rather than allowed to redefine modern semantics.\n3. Make displacement a guaranteed terminal lane, not `old.tx.try_send`. Today the different-node path at `broker.rs:1343-1344` ignores `Full`/`Disconnected`; a full 4096-frame controller queue can lose the loud notice and reproduce the same orphan shape cross-node. Give `ControllerSink` a separate revocation/terminal slot observed by its writer, set it before dropping the output sender, have the writer abort queued output, perform one bounded `Displaced` write, and exit. If the physical write fails, poison/close the old connection so its serve worker observes EOF. Never block the OutputLog/drain lock. This keeps output backpressure bounded while making terminal teardown non-droppable.\n4. Enforce current controller identity on input at the broker, mirroring resize. Clone the session log with the input writer and reject `KIND_INPUT` unless `log.is_controller(send)` (or, after the stronger model, its attach id matches). This closes the interval before the old serve consumes Displaced and prevents any orphan/stale worker from remaining input-capable. Viewer and endpoint-injection paths remain separate.\n5. Make serve teardown authority-derived. A displaced path already correctly avoids a dormant edge. For normal EOF, do not fire `feed_rest(Detach)` solely from cached `ServeRole::Controller`; have unsubscribe report whether this worker actually released the current controller (or otherwise validate attach id), and emit the rest edge only for the current owner. This prevents an old same-node viewport’s late close from putting a still-controlled endpoint dormant.\n6. Preserve writer invariants: bump epoch before any successor output; epoch-cancel old data writers; serialize the terminal Displaced after any already-in-flight frame but before successor-visible teardown completion; keep `delivered_through` advanced only by successful controller Output, never by terminal control. Keep the stamp continuously controlled across replacement and let the old generation/token’s late detach be a no-op.\n\nSecondary robustness finding\n\nEven outside the same-node root, `old.tx.try_send(CtrlMsg::Control(displaced))` followed immediately by sink replacement is best-effort. If Q1 is Full, the result is discarded; the old writer drains/ends without any notice and its serve stream can remain alive.

cause: same-machine `spt rc … --take` is misclassified as a brain-restart reconstruction because controller identity is only the origin node id. A local rc rides the broker’s reused loopback connection, whose inbound streams all carry this node’s own key (`nethost.rs:1661-1692`). `serve_attach` forwards that origin as `SubscribeReq.by` (`attach.rs:242-265`). Therefore the old and new rc both reach `OutputLog::resolve_subscribe` with the same `by`. At `broker.rs:1296-1318`, the `same_identity` arm runs before the `AttachIntent::Take` arm at `1334-1347`; a newer same-node `Take` is consequently treated as a silent successor re-take, returns `SubscribeOutcome::Controller`, and never enqueues `Displaced`. `become_controller` then removes the old `ControllerSink`, increments `controller_epoch`, and installs the new writer (`broker.rs:1005-1068`). Broker truth is still exactly one controller—the new sink—but the old target-side `serve_attach` worker remains alive with cached `ServeRole::Controller`, because sink replacement neither closes its broker connection nor emits a terminal event. Output fan-out now targets only the new sink, so the old rc freezes after any already-queued output drains. Worse, the stale worker can still forward keystrokes: `serve_attach` gates input only on its cached role (`attach.rs:456-493`), while `Broker::dispatch_input` performs no current-controller identity check (`broker.rs:3920-3998`). Resize does perform the correct `is_controller(send)` check (`broker.rs:4200-4213`), proving the missing input authorization seam. The apparent dual-controller state is thus: one broker output controller, two input-capable serve loops, one frozen rc viewport. Persisted control state does not distinguish them: `stamp_driven_by` records only `controller_by`/any-controller (`broker.rs:1458-1472`), and both viewports have the same node id, so `driven_by=<this-node>, controlled=true` remains unchanged and truth-convergence correctly continues to see one current controller (`broker.rs:3351-3410`).\",\"files\":[{\"path\":\"crates/spt-daemon/src/nethost.rs\",\"description\":\"Same-node identity source. `NetHost::dial_loopback` at lines 1661-1692 returns a reused singleton connection and stamps `remote_id_hex` as this node’s own public key. `open_stream` at 1694+ creates distinct cross-wired stream pairs, but every local rc stream has the same origin node. The unit at 2315+ explicitly proves singleton + own-node origin.\"},{\"path\":\"crates/spt/src/rc.rs\",\"description\":\"Operator path. `establish_attach` at 1417-1517 resolves a local session, calls `net_dial_loopback`, opens a fresh attach stream, and sends the requested intent. The old rc pump exits only on an `AttachRecord::Displaced`, stream EOF, exit, or transport failure (`pump`, especially 1955-2003); because the same-node broker path emits none of those, the old terminal remains raw/attached and waits indefinitely while receiving no new PTY output.\"},{\"path\":\"crates/spt-daemon/src/attach.rs\",\"description\":\"Wire-to-broker bridge and stale-role source. `request_attach_endpoint` at 658-689 mints a per-request wall-ms `gen` and carries `Take`. `handle_attach_request` at 242-265 converts every non-viewer request into `brain.attach_as(..., Some(origin_node))`. `serve_attach` caches `intent`, `role`, `attached_session`, and `serve_gen` at 336-354; it marks the role Controller on `Subscribed::{Controller,TookControl}` at 515-529. Input at 456-493 is authorized only by that cached role. A real `Displaced` is forwarded with FIN and returns at 549-555, but the same-node path never receives it. Normal EOF teardown at 579-595 uses generation-validated unsubscribe, so a late old detach cannot clear the newer broker slot, although its stale cached Controller role can still fire a resting Detach edge.\"},{\"path\":\"crates/spt-daemon/src/broker.rs\",\"description\":\"Root and lifecycle. `ControllerSink`/`OutputLog` at 539-650 separate node identity (`by`), connection identity (`SharedSend`), attach generation, writer queue, and epoch. `become_controller` at 1005-1068 drops the old sink, bumps the epoch, spawns the new writer, and re-stamps control, but does not notify or close the old serve connection. `resolve_subscribe` at 1263-1352 checks same node at 1296 before inspecting `Take` at 1335, making same-node Take a silent re-take. Detach and resize correctly use `Arc::ptr_eq` connection identity (`detach_if` 1396-1429; `is_controller` 1518-1523), but arbitration does not. `controller_writer` at 1671-1778 epoch-gates only the initial batch; after replacement the old live queue may drain, then closes with only a lifecycle log—no broker event to the old serve worker. `dispatch_input` at 3920+ accepts any connection’s session input, unlike controller-exclusive resize at 4200+. Control stamps at 1458+ and sessions convergence at 3321-3428 describe the one current broker slot, not individual viewport ownership.\"},{\"path\":\"crates/spt-daemon/src/brain.rs\",\"description\":\"Broker client semantics. `attach_as` at 982-999 carries intent, gen, and node identity. The caution at 1771-1788 already documents the generic failure shape: a same-identity silent re-take orphans the prior local controller, stops its output, does not close its connection, and freezes it.

Old local rc opens attach stream S1 through `establish_attach`; loopback gives origin `N=self-node`. Target dispatcher creates serve worker W1 with its own broker `Brain` connection C1. W1 sends `SubscribeReq { intent=Control, by=Some(N), gen=G1 }`. Broker installs `ControllerSink { send=C1, by=N, attach_gen=G1, tx=Q1 }`; writer E1 drains Q1 to C1. W1 caches `role=Controller`; the perch reads `driven_by=N, controlled=true`.\\n2. New local `rc --take` opens a different attach stream S2, but the reused loopback connection gives the same origin N. Target creates W2/C2 and sends `SubscribeReq { intent=Take, by=Some(N), gen=G2 }`, normally G2>G1.\\n3. In `resolve_subscribe`, `controller_by()==by` is true. Generation validation rejects only G2<G1; newer/equal generations enter silent re-take. The function never reaches the Take match. No `CtrlMsg::Control(Displaced)` is created and W2 receives `SubscribeOutcome::Controller`, not `TookControl`.\\n4. `become_controller` takes/drops Q1’s sink, increments `controller_epoch`, and installs Q2/E2/C2. OutputLog now has exactly one controller: C2. E1’s initial replay is epoch-canceled; its already-queued live frames can still drain because the live loop deliberately has no epoch gate, after which Q1 closes and E1 exits. Writer exit emits only `CONN_LIFECYCLE`; it does not close C1 or produce `BrokerEvent::Displaced`/EOF.\\n5. W1 is still subscribed to S1 and still caches Controller. S1 is ConnectionBound to the old rc’s still-live broker connection, so no FIN is generated. Old rc remains in `pump`, gets no output, no Displaced, and no EOF. W1 continues converting old rc Input records to `KIND_INPUT`; broker accepts them because `dispatch_input` never validates C1 against the current controller C2. The old rc therefore still types into the PTY while only the new rc renders output. Old resize is rejected because resize does validate C1; the ignored error makes this asymmetry invisible to the operator.\\n6. The persisted stamp stays stable because both old/new identities are N and the slot never becomes empty. If W1 later detaches, `detach_session_gen(G1)` cannot clear C2/G2, which is correct for the broker slot. However W1’s cached Controller role fires `feed_rest(Detach)` before that no-op unsubscribe, so stale teardown can also mark the endpoint dormant while W2 is still driving—an adjacent lifecycle consequence.\\n\\nWhy this is deterministic, not a writer race\\n\\nThe decisive branch is pure: same `by`, non-older `gen`, any non-Viewer intent => silent `become_controller`. Queue timing changes only how many final old output frames drain. It cannot create a Displaced frame because the only enqueue site is in the later different-remote Take branch. The apparent dual state does not require queue overflow, a stalled pipe, brain restart, or persisted-state corruption.\\n\\nFalsifiable regression test\\n\\nAdd `same_node_take_displaces_distinct_viewport_and_revokes_old_input` beside `controller_viewer_matrix_and_loud_take` in `crates/spt-daemon/tests/attach.rs`, using real broker connections and pump-mode bounded reads:\\n\\n- A: `attach_as(sid, 0, Control, 100, Some(\\\"node-A\\\"))`; require `Controller`.\\n- B: `attach_as(sid, 0, Take, 200, Some(\\\"node-A\\\"))`; this models two viewports on one node but distinct requests.\\n- Required contract: B receives `TookControl`; A receives exactly one `BrokerEvent::Displaced { by: \\\"node-A\\\" }` and then its serve terminates; only B receives subsequent PTY output.\\n- Authorization assertion: after takeover, input submitted over A/C1 must be rejected/not reach the PTY; input over B/C2 must echo to B. Resize already provides the reference implementation for this identity check.\\n- Stamp assertion with a seeded perch: throughout the atomic takeover, `controlled=true` and `driven_by=node-A`; A’s late generation-100 unsubscribe must not clear B/G2.\\n- Reconstruction control arm: repeat a subscribe with the SAME logical attach token/request generation and require silent `Controller`, no Displaced, preserving ADR-0038 redispatch behavior.\\n\\nCurrent-code prediction `[INFERENCE, source-determined; tests were intentionally not executed under the read-only/skip-tests constraint]`: B returns `Controller`, A times out waiting for Displaced, PTY output appears only on B after Q1 drains, and input sent by A is accepted and echoed to B. This distinguishes the bug from a broker dual-slot claim.\\n\\nA production-faithful manual repro is equally sharp: run a continuously repainting/echoing hosted endpoint; attach rc A locally; attach rc B locally with `--take`; type a distinct marker in A. Current prediction: A receives no displacement notice and freezes visually, B keeps rendering and shows A’s marker. Cross-node B (different node id) instead reaches the existing loud branch, isolating same-node identity collapse.\\n\\nSource-level fix proposal\\n\\nA mere reordering of `Take` before `same_identity` is insufficient: it would make a redispatched Request whose original intent was Take self-kick after a target brain restart. The correct discriminator is the attach stream/viewport lifecycle, exactly as ADR-0038 requires.\\n\\n1. Add a stable logical attach id to the broker subscribe state. Best source is the accepted attach `stream_id`, paired with `origin_node`: `(by, stream_id)` is unique per viewport, remains identical when the SAME broker-held stream is redispatched after a brain cycle, and differs for a second rc even on the reused same-node loopback connection. Thread it from `serve_attach` through `Brain::attach_as`/`SubscribeReq` into `ControllerSink`. Keep it additive/defaulted for N-1. Do not rely solely on wall-ms `gen`: it can collide within a millisecond and is ordering metadata, not identity.\\n2. Resolve by logical ownership, not node:\\n   - Viewer: unchanged.\\n   - No controller: install.\\n   - Same attach id (same stream reconstruction or same-worker gap resume): silent/idempotent re-take; no Displaced.\\n   - Different attach id + Take: revoke incumbent, return TookControl, regardless of whether `by` is the same node or a different node.\\n   - Different attach id + Control: BusyControlled, including a second same-node plain rc.\\n   - Preserve the explicit local-spawner-placeholder rule (`by=None`, no operator attach id) so the first real rc can claim an otherwise undriven spawned session without a fake kick. Legacy absent-id behavior must be deliberately compatibility-gated rather than allowed to redefine modern semantics.\\n3. Make displacement a guaranteed terminal lane, not `old.tx.try_send`. Today the different-node path at `broker.rs:1343-1344` ignores `Full`/`Disconnected`; a full 4096-frame controller queue can lose the loud notice and reproduce the same orphan shape cross-node. Give `ControllerSink` a separate revocation/terminal slot observed by its writer, set it before dropping the output sender, have the writer abort queued output, perform one bounded `Displaced` write, and exit. If the physical write fails, poison/close the old connection so its serve worker observes EOF. Never block the OutputLog/drain lock. This keeps output backpressure bounded while making terminal teardown non-droppable.\\n4. Enforce current controller identity on input at the broker, mirroring resize. Clone the session log with the input writer and reject `KIND_INPUT` unless `log.is_controller(send)` (or, after the stronger model, its attach id matches). This closes the interval before the old serve consumes Displaced and prevents any orphan/stale worker from remaining input-capable. Viewer and endpoint-injection paths remain separate.\\n5. Make serve teardown authority-derived. A displaced path already correctly avoids a dormant edge. For normal EOF, do not fire `feed_rest(Detach)` solely from cached `ServeRole::Controller`; have unsubscribe report whether this worker actually released the current controller (or otherwise validate attach id), and emit the rest edge only for the current owner. This prevents an old same-node viewport’s late close from putting a still-controlled endpoint dormant.\\n6. Preserve writer invariants: bump epoch before any successor output; epoch-cancel old data writers; serialize the terminal Displaced after any already-in-flight frame but before successor-visible teardown completion; keep `delivered_through` advanced only by successful controller Output, never by terminal control. Keep the stamp continuously controlled across replacement and let the old generation/token’s late detach be a no-op.\\n\\nSecondary robustness finding\\n\\nEven outside the same-node root, `old.tx.try_send(CtrlMsg::Control(displaced))` followed immediately by sink replacement is best-effort. If Q1 is Full, the result is discarded; the old writer drains/ends without any notice and its serve stream can remain alive. A gate-pinned writer plus a filled controller channel makes this independently deterministic. The terminal-lane fix above should therefore accompany the identity fix; otherwise same-node takeover is repaired while the stated `REQ-KICK-1` loud/full-detach contract remains falsifiable under backpressure.\"}}}","call_id":"call_lTH642t4Dvs6vetP3qyn8OCp","name":"yield"}]},"duration":244597.70680001378,"ttft":1668.6454000175,"contextSnapshot":{"promptTokens":192018,"nonMessageTokens":15565}}}

A local rc rides the broker’s reused loopback connection, whose inbound streams all carry this node’s own key (`nethost.rs:1661-1692`). `serve_attach` forwards that origin as `SubscribeReq.by` (`attach.rs:242-265`). Therefore the old and new rc both reach `OutputLog::resolve_subscribe` with the same `by`. At `broker.rs:1296-1318`, the `same_identity` arm runs before the `AttachIntent::Take` arm at `1334-1347`; a newer same-node `Take` is consequently treated as a silent successor re-take, returns `SubscribeOutcome::Controller`, and never enqueues `Displaced`. `become_controller` then removes the old `ControllerSink`, increments `controller_epoch`, and installs the new writer (`broker.rs:1005-1068`). Broker truth is still exactly one controller—the new sink—but the old target-side `serve_attach` worker remains alive with cached `ServeRole::Controller`, because sink replacement neither closes its broker connection nor emits a terminal event. Output fan-out now targets only the new sink, so the old rc freezes after any already-queued output drains. Worse, the stale worker can still forward keystrokes: `serve_attach` gates input only on its cached role (`attach.rs:456-493`), while `Broker::dispatch_input` performs no current-controller identity check (`broker.rs:3920-3998`). Resize does perform the correct `is_controller(send)` check (`broker.rs:4200-4213`), proving the missing input authorization seam. The apparent dual-controller state is thus: one broker output controller, two input-capable serve loops, one frozen rc viewport. Persisted control state does not distinguish them: `stamp_driven_by` records only `controller_by`/any-controller (`broker.rs:1458-1472`), and both viewports have the same node id, so `driven_by=<this-node>, controlled=true` remains unchanged and truth-convergence correctly continues to see one current controller (`broker.rs:3351-3410`).","files":[{"path":"crates/spt-daemon/src/nethost.rs","description":"Same-node identity source. `NetHost::dial_loopback` at lines 1661-1692 returns a reused singleton connection and stamps `remote_id_hex` as this node’s own public key. `open_stream` at 1694+ creates distinct cross-wired stream pairs, but every local rc stream has the same origin node.

Old local rc opens attach stream S1 through `establish_attach`; loopback gives origin `N=self-node`. Target dispatcher creates serve worker W1 with its own broker `Brain` connection C1. W1 sends `SubscribeReq { intent=Control, by=Some(N), gen=G1 }`. Broker installs `ControllerSink { send=C1, by=N, attach_gen=G1, tx=Q1 }`; writer E1 drains Q1 to C1. W1 caches `role=Controller`; the perch reads `driven_by=N, controlled=true`.\n2. New local `rc --take` opens a different attach stream S2, but the reused loopback connection gives the same origin N. Target creates W2/C2 and sends `SubscribeReq { intent=Take, by=Some(N), gen=G2 }`, normally G2>G1.\n3. In `resolve_subscribe`, `controller_by()==by` is true. Generation validation rejects only G2<G1; newer/equal generations enter silent re-take. The function never reaches the Take match. No `CtrlMsg::Control(Displaced)` is created and W2 receives `SubscribeOutcome::Controller`, not `TookControl`.\n4. `become_controller` takes/drops Q1’s sink, increments `controller_epoch`, and installs Q2/E2/C2. OutputLog now has exactly one controller: C2. E1’s initial replay is epoch-canceled; its already-queued live frames can still drain because the live loop deliberately has no epoch gate, after which Q1 closes and E1 exits. Writer exit emits only `CONN_LIFECYCLE`; it does not close C1 or produce `BrokerEvent::Displaced`/EOF.\n5. W1 is still subscribed to S1 and still caches Controller. S1 is ConnectionBound to the old rc’s still-live broker connection, so no FIN is generated. Old rc remains in `pump`, gets no output, no Displaced, and no EOF. W1 continues converting old rc Input records to `KIND_INPUT`; broker accepts them because `dispatch_input` never validates C1 against the current controller C2. The old rc therefore still types into the PTY while only the new rc renders output. Old resize is rejected because resize does validate C1; the ignored error makes this asymmetry invisible to the operator.\n6. The persisted stamp stays stable because both old/new identities are N and the slot never becomes empty. If W1 later detaches, `detach_session_gen(G1)` cannot clear C2/G2, which is correct for the broker slot. However W1’s cached Controller role fires `feed_rest(Detach)` before that no-op unsubscribe, so stale teardown can also mark the endpoint dormant while W2 is still driving—an adjacent lifecycle consequence.\n\nWhy this is deterministic, not a writer race\n\nThe decisive branch is pure: same `by`, non-older `gen`, any non-Viewer intent => silent `become_controller`.

Local rc uses a broker-minted loopback stream whose `remote_id_hex` is always this node’s own key (`crates/spt-daemon/src/nethost.rs:1661-1692`). Each rc gets a distinct stream, but both reach `serve_attach` with the same `origin_node`; `handle_attach_request` passes that value as `SubscribeReq.by` (`attach.rs:242-265`). In `OutputLog::resolve_subscribe`, node equality is checked before intent (`broker.rs:1296-1318` precedes the Take match at `1334-1347`). Thus the second same-node `Take` is treated as a silent brain-restart successor: it returns `SubscribeOutcome::Controller`, never `TookControl`, and never sends `Displaced`. `become_controller` removes the old sink/writer and installs the new one (`1005-1068`), so broker controller truth is singular and output moves to the new rc. However, removing a sink does not close the old target serve connection or terminate its network stream; the old `serve_attach` loop retains cached `ServeRole::Controller`, receives neither Displaced nor EOF, and remains attached without new output. Its input path still calls generic `KIND_INPUT`, which has no attach-ownership validation, so the old rc can continue typing while only the new rc renders. The persisted `driven_by`/`controlled` stamp remains truthfully set for the single current broker controller, but it is node-scoped and both viewports have the same node id, so it cannot reveal the orphan.

The peer row carries origin N, the local node key. Dispatcher worker W1 opens broker connection C1 and subscribes `{by:N, gen:G1, intent:Control}`. OutputLog installs sink/writer Q1/E1/C1. W1 caches Controller. Perch becomes `driven_by=N, controlled=true`.\n2. rc B opens distinct loopback attach stream S2, but because loopback origin is node-scoped it also carries N. Worker W2/C2 subscribes `{by:N, gen:G2, intent:Take}`, normally G2>G1.\n3. `same_identity` is true. Only older nonzero generations are rejected. G2 is newer, so the silent-reconstruction arm runs and calls `become_controller`; the Take arm is unreachable. B gets `Controller`, not `TookControl`; A gets no Displaced.\n4. `become_controller` removes Q1, increments the shared epoch, creates Q2/E2, and stamps the same N/true values. E1’s initial replay is epoch-canceled; already-queued live frames may drain because the live writer path intentionally is not epoch-gated. Once Q1 closes, E1 exits, but emits only `CONN_LIFECYCLE`, not a broker event.\n5. OutputLog now routes every new Output only to Q2. This proves broker truth is one controller, C2—not two. W1 nevertheless remains blocked on C1 with cached Controller because S1 is still open and no event revoked it. rc A therefore remains attached but visually freezes.\n6. Input from rc A still traverses S1 → W1 → `send_effect_no_ack(Minter::Rc)` → generic `dispatch_input`, so it can alter the PTY. Output from that alteration goes to B. Old resize is rejected because resize validates current `SharedSend`; the ignored rejection exposes the input/resize authorization asymmetry.\n7. Control convergence keeps `driven_by=N, controlled=true`: that is correct for C2 but too coarse to identify A versus B. A late generation-G1 unsubscribe cannot clear C2/G2, which protects the stamp. However, W1’s cached role can still fire a stale resting Detach edge before its unsubscribe no-ops—an adjacent teardown consequence.\n\nQUEUE / SIGNALING FINDING\n\nThe same-machine root does not require queue pressure: no Displaced is attempted at all. There is also an independent robustness hole in the different-node Take path: `old.tx.try_send(CtrlMsg::Control(displaced))` ignores Full/Disconnected, then `become_controller` drops the old sink. A full controller queue can therefore lose the loud notice, let the old writer close after backlog, and orphan the old serve loop in the same way. REQ-KICK-1 promises loud full detach, so a correct fix must not leave terminal signaling on a best-effort data queue.\n\nFALSIFIABLE TEST\n\nAdd `same_node_take_displaces_distinct_viewport_and_revokes_old_rc_input` next to the existing matrix in `crates/spt-daemon/tests/attach.rs` using real broker pump connections and bounded reads:\n\n- A: `attach_as(sid,0,Control,100,Some(\"node-A\"))`; assert Controller.\n- B: `attach_as(sid,0,Take,200,Some(\"node-A\"))`; required assertion is TookControl.\n- A must receive exactly one `BrokerEvent::Displaced{by:\"node-A\"}` and terminate, not become a viewer.\n- Subsequent output must appear only on B.\n- Submit RC-token-bearing input from A after broker takeover but before it consumes Displaced; assert it is rejected/not written.

Introduce stable logical attach ownership keyed by stream lifecycle, not node. The best token is `(origin_node, accepted_attach_stream_id)`: it differs for two same-machine rc viewports, but remains identical when the same broker-held stream is redispatched after a brain restart. Thread an additive `attach_id` from `serve_attach(stream_id)` through `Brain::attach_as`/`SubscribeReq` into `ControllerSink`. Keep `gen` for stale-order rejection, but do not use wall-ms alone as identity—it can collide and is not lifecycle truth.\n2. Arbitration matrix:\n   - Viewer unchanged.\n   - No controller: install.\n   - Same attach_id: silent/idempotent reconstruction or gap-resume; no Displaced.\n   - Different attach_id + Take: revoke incumbent and return TookControl regardless of whether `by` is the same node or another node.\n   - Different attach_id + Control: BusyControlled, including a second same-node plain rc.\n   - Preserve the special local spawner placeholder (`by=None`, no operator attach token) so the first real rc can claim an otherwise undriven spawned session without a fake kick. N-1 absent-token behavior must be explicitly compatibility-scoped.\n3. Do not merely move Take before same_identity: a redispatched stream whose original Request intent was Take would then self-kick. The lifecycle token is required to separate same Request from same node.\n4. Make displacement terminal and non-droppable without blocking the OutputLog lock. Give `ControllerSink` a separate revocation slot/lane observed by its writer. On takeover: set revocation, bump epoch/cancel old data, drop/wake the data queue, perform one bounded Displaced write, then end the old connection/serve ownership. If the terminal write fails, poison/close the old connection so EOF tears the worker down. Do not enqueue terminal control with best-effort `try_send` into a possibly full output queue.\n5. Revoke stale RC input at the broker, but do NOT globally gate generic `KIND_INPUT`: `shellchan` and system/test callers legitimately use it from non-controller connections. Correct options are (a) add optional `attach_id`/expected-controller token fields to RC-origin `InputReq` and validate only token-bearing/Minter::Rc requests, with absent token retaining legacy/system semantics, or preferably (b) add a dedicated guarded RC-input broker verb/API. Resize should validate the same token. This closes the takeover-to-notice race while preserving shell/system injection.\n6. Teardown should consult live ownership, not only cached ServeRole. Have unsubscribe return whether this worker actually released the current controller (or validate attach_id before resting transition), and fire `feed_rest(Detach)` only for the real current owner. A Displaced path remains wake-neutral as today.\n7. Preserve writer/stamp invariants: epoch changes before successor output; old data writers cannot emit after revocation except an already-in-flight frame; terminal Displaced does not advance `delivered_through`; replacement stays continuously `controlled=true`; old-token disconnect/unsubscribe cannot clear the new controller.\n\nThis fix makes broker truth, output routing, input authorization, stream teardown, rc UI termination, and persisted control projection agree while preserving legitimate silent redispatch."}}}}],"api":"openai-codex-responses","provider":"openai-codex","model":"gpt-5.6-sol","usage":{"input":887,"output":3363,"cacheRead":202240,"cacheWrite":0,"totalTokens":206490,"reasoningTokens":109,"cost":{"input":0.004435000000000001,"output":0.10089000000000001,"cacheRead":0.10112,"cacheWrite":0,"total":0.206445}},"stopReason":"toolUse","timestamp":1784370476790,"responseId":"resp_08878c25321feb39016a5b552d1188819abf162b85f8da130d","providerPayload":{"type":"openaiResponsesHistory","provider":"openai-codex","dt":true,"items":[{"id":"rs_08878c25321feb39016a5b552efd88819a954781bdfab667cb","type":"reasoning","content":[],"encrypted_content":"gAAAAABqW1WOlpSCSgDmSuNZSit8_h3n884Qa-5P_R0aPzdvrdBDy3CHaLl1W1lT2YckhX_lLEOdAQcW5cZVK_G8BWs2zjgx3w02JVijEbbcuT_pbwPoMZ8fNcYQ1EJgCKC8aKvWdJ8CCdYEDj9T0mM8Q1sHZ9OS8fE8PIbGw4uvTyC80hwN9Nt5FDQg8SBVKn_T0Im8JbQ5cnMLu2d2IPTBLcIMfGRPlx7ZzWBxlpws-f-DkEiE60QMuV67ab2zSo5lv59VkTPQ_8C4OToHlk8n59mNtXgJoNxikpTiZcbcl4csiycNSZ0UNKOP8pZvXJ9JGOyzGJCdRQIzEJNPyYwPV6NhzVok9zxmHULQOOvxGpxXO4rcuz8nTaTOsk4faCIPLBzarO4hewAvb_MJ8RbKZH6fk8kY8NNVBviyYmTyzsC2-cojPg-mdAT6GaLDXerDYMzcTs-BKqyFO3p_OwKMdrvcqdrIdx929fE_yW50pc1qbo-OPXqVz8dmTfJjxWBlTIeJK9o158joZzzJXMViSKBMqkbfgK2tcpx1pGtrdbpaQJGQFvpgYxcPtFUm-2IYdaJQsEEYxQK0Tn_XIR0eJcOg25o64WXdYXss3EL5jp3X0vCjU9auqO5b8IOyJF7h-gZDGNQL-NtOq2aC-k-fOEVlKxDN4C8tVRWsPQrH_CGymjjFdsdTQI3uiWDUCF5AEQZ3y_YQ3arkBvoef8HGm8nIOiXscFrSaZF9FdKxAkV39sqUmD27Fee3s6wGcyg-foxlFuHIhsEo6D6mrLInKaVAVCroRtyW2DBUqeO4Rut1eC6MMndXckLavrmle8gr-59EOPJRcunMUxtbapGgjwYUuuHn5mR76RreBw39d-J53584SHYtZkko_PP6wyna9TD8QDyPuvMTdgbZycOjawfWa-5CGWs3O73ueJ99iqkCZ14ViLZrt8d1xlRX3dWqaipM0IOZBy_RtC4uTgSRjhstrqNWXIqjJveZdoi3O3kOCnoCbab7LfAxPIMsj8Ksyy1ayOGBsDhnv3hr97OdCfNQN9X513zieSSeYb7CeMzJboaSOrlIFfcqL-lxO4aJs6Q8dJU4v_t9uu9naKm9me6rbc2UR6eM4wEzjUUjfjQEUg4_SsmNLDuFic6PhndyR6UnzSsYWu1Yl2dncgYnTdRpHR5ZBFwOmeA7xXj3GjZ-FRGUroJFJSr7x1gbdHOwwUwukApUdtLKh8q08Nw8E1cN7Zw7gHauUEBJ-SSw9Q6rag_9_Pris5gu9T3ohVe3YQGt2AKCNWtAgLD-dnGjzOUaEOs1z-OBeOmyCdgFSygXAyMhT2glOLduQbCmno3wirgopzA-65HUTYtsnbx1KSRetex87xAvAvqTmiQLYVbcq9TI7T4oVuxUiMg2vkb9q75V1uMatT0ZlH6LQ4nSKIUMEM9ryV472AxM3rrvdtts0p62cQwjXZkl72GCTwRUR9DSmqGI4c3AdBrzTGjRc8SulM8Jmsmr33Qkl1zWh3cpka4RdThVecj6KxX_DUP2N-tiLcX6yAv7gDh2WNlohWhG-ueAxlwnzMdxUVYPHPk1MoOZkRyqZmCxf7ebyGlAKacsiRmxbkz4L4SNQm-3C-_dVEKOi6W2LrE2tLA4g8CMsKNMTvjbyzkZ7vc20h6c-RfSchKkSCsWiNwUwG_3PM6gSjC3_g==","summary":[{"type":"summary_text","text":"**Updating terminal yield with corrected full data**"}]},{"id":"fc_08878c25321feb39016a5b558e6e08819a90d146be7c901d9d","type":"function_call","status":"completed","arguments":"{\"type\":\"result\",\"result\":{\"data\":{\"summary\":\"ROOT CAUSE — The broker has only one output-controller slot, but same-machine takeover leaves the old target-side attach worker alive and still authorized by its cached role.

The peer row carries origin N, the local node key. Dispatcher worker W1 opens broker connection C1 and subscribes `{by:N, gen:G1, intent:Control}`. OutputLog installs sink/writer Q1/E1/C1. W1 caches Controller. Perch becomes `driven_by=N, controlled=true`.\\n2. rc B opens distinct loopback attach stream S2, but because loopback origin is node-scoped it also carries N. Worker W2/C2 subscribes `{by:N, gen:G2, intent:Take}`, normally G2>G1.\\n3. `same_identity` is true. Only older nonzero generations are rejected. G2 is newer, so the silent-reconstruction arm runs and calls `become_controller`; the Take arm is unreachable. B gets `Controller`, not `TookControl`; A gets no Displaced.\\n4. `become_controller` removes Q1, increments the shared epoch, creates Q2/E2, and stamps the same N/true values. E1’s initial replay is epoch-canceled; already-queued live frames may drain because the live writer path intentionally is not epoch-gated. Once Q1 closes, E1 exits, but emits only `CONN_LIFECYCLE`, not a broker event.\\n5. OutputLog now routes every new Output only to Q2. This proves broker truth is one controller, C2—not two. W1 nevertheless remains blocked on C1 with cached Controller because S1 is still open and no event revoked it. rc A therefore remains attached but visually freezes.\\n6. Input from rc A still traverses S1 → W1 → `send_effect_no_ack(Minter::Rc)` → generic `dispatch_input`, so it can alter the PTY. Output from that alteration goes to B. Old resize is rejected because resize validates current `SharedSend`; the ignored rejection exposes the input/resize authorization asymmetry.\\n7. Control convergence keeps `driven_by=N, controlled=true`: that is correct for C2 but too coarse to identify A versus B. A late generation-G1 unsubscribe cannot clear C2/G2, which protects the stamp. However, W1’s cached role can still fire a stale resting Detach edge before its unsubscribe no-ops—an adjacent teardown consequence.\\n\\nQUEUE / SIGNALING FINDING\\n\\nThe same-machine root does not require queue pressure: no Displaced is attempted at all. There is also an independent robustness hole in the different-node Take path: `old.tx.try_send(CtrlMsg::Control(displaced))` ignores Full/Disconnected, then `become_controller` drops the old sink. A full controller queue can therefore lose the loud notice, let the old writer close after backlog, and orphan the old serve loop in the same way. REQ-KICK-1 promises loud full detach, so a correct fix must not leave terminal signaling on a best-effort data queue.\\n\\nFALSIFIABLE TEST\\n\\nAdd `same_node_take_displaces_distinct_viewport_and_revokes_old_rc_input` next to the existing matrix in `crates/spt-daemon/tests/attach.rs` using real broker pump connections and bounded reads:\\n\\n- A: `attach_as(sid,0,Control,100,Some(\\\"node-A\\\"))`; assert Controller.\\n- B: `attach_as(sid,0,Take,200,Some(\\\"node-A\\\"))`; required assertion is TookControl.\\n- A must receive exactly one `BrokerEvent::Displaced{by:\\\"node-A\\\"}` and terminate, not become a viewer.\\n- Subsequent output must appear only on B.\\n- Submit RC-token-bearing input from A after broker takeover but before it consumes Displaced; assert it is rejected/not written.

The peer row carries origin N, the local node key. Dispatcher worker W1 opens broker connection C1 and subscribes `{by:N, gen:G1, intent:Control}`. OutputLog installs sink/writer Q1/E1/C1. W1 caches Controller. Perch becomes `driven_by=N, controlled=true`.\n2. rc B opens distinct loopback attach stream S2, but because loopback origin is node-scoped it also carries N. Worker W2/C2 subscribes `{by:N, gen:G2, intent:Take}`, normally G2>G1.\n3. `same_identity` is true. Only older nonzero generations are rejected. G2 is newer, so the silent-reconstruction arm runs and calls `become_controller`; the Take arm is unreachable. B gets `Controller`, not `TookControl`; A gets no Displaced.\n4. `become_controller` removes Q1, increments the shared epoch, creates Q2/E2, and stamps the same N/true values. E1’s initial replay is epoch-canceled; already-queued live frames may drain because the live writer path intentionally is not epoch-gated. Once Q1 closes, E1 exits, but emits only `CONN_LIFECYCLE`, not a broker event.\n5. OutputLog now routes every new Output only to Q2. This proves broker truth is one controller, C2—not two. W1 nevertheless remains blocked on C1 with cached Controller because S1 is still open and no event revoked it. rc A therefore remains attached but visually freezes.\n6. Input from rc A still traverses S1 → W1 → `send_effect_no_ack(Minter::Rc)` → generic `dispatch_input`, so it can alter the PTY. Output from that alteration goes to B. Old resize is rejected because resize validates current `SharedSend`; the ignored rejection exposes the input/resize authorization asymmetry.\n7. Control convergence keeps `driven_by=N, controlled=true`: that is correct for C2 but too coarse to identify A versus B. A late generation-G1 unsubscribe cannot clear C2/G2, which protects the stamp. However, W1’s cached role can still fire a stale resting Detach edge before its unsubscribe no-ops—an adjacent teardown consequence.\n\nQUEUE / SIGNALING FINDING\n\nThe same-machine root does not require queue pressure: no Displaced is attempted at all. There is also an independent robustness hole in the different-node Take path: `old.tx.try_send(CtrlMsg::Control(displaced))` ignores Full/Disconnected, then `become_controller` drops the old sink. A full controller queue can therefore lose the loud notice, let the old writer close after backlog, and orphan the old serve loop in the same way. REQ-KICK-1 promises loud full detach, so a correct fix must not leave terminal signaling on a best-effort data queue.\n\nFALSIFIABLE TEST\n\nAdd `same_node_take_displaces_distinct_viewport_and_revokes_old_rc_input` next to the existing matrix in `crates/spt-daemon/tests/attach.rs` using real broker pump connections and bounded reads:\n\n- A: `attach_as(sid,0,Control,100,Some(\"node-A\"))`; assert Controller.\n- B: `attach_as(sid,0,Take,200,Some(\"node-A\"))`; required assertion is TookControl.\n- A must receive exactly one `BrokerEvent::Displaced{by:\"node-A\"}` and terminate, not become a viewer.\n- Subsequent output must appear only on B.\n- Submit RC-token-bearing input from A after broker takeover but before it consumes Displaced; assert it is rejected/not written. Submit B input; assert it echoes to B.\n- Seed a perch and assert control remains continuously true/N across the replacement; A’s late old-token unsubscribe must not clear B.\n- Control arm: re-serve the SAME logical stream/token with the same generation and assert silent Controller/no Displaced, preserving ADR-0038 brain-restart reconstruction.\n\nCurrent-source prediction `[INFERENCE; tests intentionally not executed under the assignment’s read-only/skip-tests constraint]`: B receives Controller, A times out waiting for Displaced, B alone receives new output, and generic RC input sent through A is accepted and its echo appears on B.\n\nA production repro is equally discriminating: host a continuously repainting/echoing endpoint; open local rc A; open local rc B with `--take`; type a unique marker in A. Current prediction is no displacement line in A, A’s display freezes, B keeps repainting and shows A’s marker. Running B from a different node reaches the existing loud branch and separates the same-node cause from generic writer failure.\n\nSOURCE-LEVEL FIX\n\n1. Introduce stable logical attach ownership keyed by stream lifecycle, not node. The best token is `(origin_node, accepted_attach_stream_id)`: it differs for two same-machine rc viewports, but remains identical when the same broker-held stream is redispatched after a brain restart. Thread an additive `attach_id` from `serve_attach(stream_id)` through `Brain::attach_as`/`SubscribeReq` into `ControllerSink`. Keep `gen` for stale-order rejection, but do not use wall-ms alone as identity—it can collide and is not lifecycle truth.\n2. Arbitration matrix:\n   - Viewer unchanged.\n   - No controller: install.\n   - Same attach_id: silent/idempotent reconstruction or gap-resume; no Displaced.\n   - Different attach_id + Take: revoke incumbent and return TookControl regardless of whether `by` is the same node or another node.\n   - Different attach_id + Control: BusyControlled, including a second same-node plain rc.\n   - Preserve the special local spawner placeholder (`by=None`, no operator attach token) so the first real rc can claim an otherwise undriven spawned session without a fake kick. N-1 absent-token behavior must be explicitly compatibility-scoped.\n3. Do not merely move Take before same_identity: a redispatched stream whose original Request intent was Take would then self-kick. The lifecycle token is required to separate same Request from same node.\n4. Make displacement terminal and non-droppable without blocking the OutputLog lock. Give `ControllerSink` a separate revocation slot/lane observed by its writer. On takeover: set revocation, bump epoch/cancel old data, drop/wake the data queue, perform one bounded Displaced write, then end the old connection/serve ownership. If the terminal write fails, poison/close the old connection so EOF tears the worker down. Do not enqueue terminal control with best-effort `try_send` into a possibly full output queue.\n5. Revoke stale RC input at the broker, but do NOT globally gate generic `KIND_INPUT`: `shellchan` and system/test callers legitimately use it from non-controller connections. Correct options are (a) add optional `attach_id`/expected-controller token fields to RC-origin `InputReq` and validate only token-bearing/Minter::Rc requests, with absent token retaining legacy/system semantics, or preferably (b) add a dedicated guarded RC-input broker verb/API. Resize should validate the same token. This closes the takeover-to-notice race while preserving shell/system injection.\n6. Teardown should consult live ownership, not only cached ServeRole. Have unsubscribe return whether this worker actually released the current controller (or validate attach_id before resting transition), and fire `feed_rest(Detach)` only for the real current owner. A Displaced path remains wake-neutral as today.\n7. Preserve writer/stamp invariants: epoch changes before successor output; old data writers cannot emit after revocation except an already-in-flight frame; terminal Displaced does not advance `delivered_through`; replacement stays continuously `controlled=true`; old-token disconnect/unsubscribe cannot clear the new controller.\n\nThis fix makes broker truth, output routing, input authorization, stream teardown, rc UI termination, and persisted control projection agree while preserving legitimate silent redispatch."},"status":"success","type":"result"},"isError":false,"timestamp":1784370574463}}
