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.

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.

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.

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: **RC Protocol 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.

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. Watch the bug appear.\n\nConfirm:\n\n- [ ] The loop produces the failure mode the **user** described — not a different failure that happens to be nearby. Wrong bug = wrong fix.\n- [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).\n- [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.\n\nDo not proceed until you reproduce the bug.\n\n## Phase 3 — Hypothesise\n\nGenerate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.\n\nEach hypothesis must be **falsifiable**: state the prediction it makes.\n\n> Format: \"If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse.\"\n\nIf you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.\n\n**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly (\"we just deployed a change to #3\"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver.

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. Single-hypothesis generation anchors on the first plausible idea.\r\n\r\nEach hypothesis must be **falsifiable**: state the prediction it makes.\r\n\r\n> Format: \"If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse.\"\r\n\r\nIf you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.\r\n\r\n**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly (\"we just deployed a change to #3\"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it — proceed with your ranking if the user is AFK.\r\n\r\n## Phase 4 — Instrument\r\n\r\nEach probe must map to a specific prediction from Phase 3. **Change one variable at a time.**\r\n\r\nTool preference:\r\n\r\n1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.\r\n2. **Targeted logs** at the boundaries that distinguish hypotheses.\r\n3. Never \"log everything and grep\".\r\n\r\n**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.\r\n\r\n**Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.\r\n\r\n## Phase 5 — Fix + regression test\r\n\r\nWrite the regression test **before the fix** — but only if there is a **correct seam** for it.\r\n\r\nA correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site.

Current unit `same_identity_resubscribe_refuses_a_stale_generation` broker.rs:6178-6240 explicitly (and incorrectly for this bug) allows 'equal or newer'; update it. Add deterministic tests/attach.rs seam: A Control by=node-A gen100, B Take same by gen200 => TookControl + A Displaced; current result Controller/no notice.

In `OutputLog::resolve_subscribe` (`crates/spt-daemon/src/broker.rs:1296-1318`), `same_identity` is handled before `AttachIntent`; every equal-or-newer generation silently calls `become_controller` and returns `Controller`. Therefore a same-node `Take` never reaches the only loud-displacement arm at `1335-1347`. `become_controller` drops the incumbent output sink, so the original `rc` immediately stops receiving PTY output, but it does not close the original attach stream or revoke its target-side `serve_attach` worker. No `BrokerEvent::Displaced` is produced, hence no `AttachRecord::Displaced` or FIN reaches the original pump. The new `rc` attaches and renders, while the original process remains alive. More seriously, the original serve worker's local `role` remains `Controller`, and its input path (`attach.rs:470-490`) still calls generic `send_effect_no_ack`; `dispatch_input` (`broker.rs:3920-3988`) does not validate that the sending broker connection is the current controller. Thus broker output-controller truth is singular (the new sink), but both attach workers can still inject keystrokes: the apparent dual controller includes a real dual-input defect.

Clean operator FIN handling is 580-596: resting Detach first, then generation-validated `detach_session_gen`.

The only `Take`/Displaced arm is restricted to a DIFFERENT remote at 1335-1347. Persisted stamps are node+boolean only (`stamp_driven_by`, 1450-1473), so replacing one same-node viewport with another writes identical `driven_by`/`controlled` values and cannot expose the orphan worker. `detach_if_gen` (1395-1417) correctly prevents the old generation's later FIN from clearing the new slot. `controller_writer` (1671-1773) deliberately drains queued terminal control frames after supersession, but loud displacement is only best-effort: `old.tx.try_send(CtrlMsg::Control(...))` at 1342-1344 ignores Full/Disconnected.

Original CLI O: `spt rc deployah` parses to `AttachIntent::Control` (`cli.rs:1426-1428,1719-1727`). `run_attach_inner` may consult persisted `driven_by` only for Control (`rc.rs:1136-1147`). On the first attach the slot is ordinarily free or held only by the broker's local spawn reader.\n\n2. Establish O: `establish_attach` resolves deployah locally first. Local uses the broker loopback connection; remote uses the owner node's QUIC connection. The protocol above the transport leaf is identical. `request_attach_endpoint` opens a ConnectionBound stream and sends `Request{intent:Control,gen:now_ms()}`. For local loopback, the target stream's proven origin is this node's own id; for remote, it is the operator node's handshake id. In both cases two rc processes on the same operator machine have the same `by`.\n\n3. Serve O: dispatcher identifies the peer-initiated Attach stream and calls `serve_attach`; `handle_attach_request` calls `Brain::attach_as(session, Control, gen_O, Some(origin))`. The broker resolves O as Controller, installs O's ControllerSink, and stamps `driven_by=origin`, `controlled=true`. O's target serve worker records `role=Controller`; O's operator pump renders Output and sends Input.\n\n4. Takeover CLI T: `spt rc deployah --take` maps correctly to Take and bypasses the Control-only persisted-driver refusal. It establishes a second ConnectionBound attach stream with the same `by` and normally `gen_T > gen_O`.\n\n5. Defective broker transition: `resolve_subscribe` sees `controller_by()==by` and enters `same_identity` before looking at Take. Because `gen_T` is not older, it calls `become_controller`, returns ordinary `Controller`, and never executes the loud Take arm. Broker truth now has exactly one ControllerSink: T. `become_controller` drops O's sink/writer path and installs T's, so all new PTY Output goes to T. Persisted stamps remain `driven_by=the same node`, `controlled=true`; no durable projection changes.\n\n6. Orphan O: dropping O's ControllerSink is not equivalent to detaching O's attach protocol. O's operator connection is alive, so ConnectionBound does not synthesize FIN. O's target-side attach stream subscription and `serve_attach` loop remain alive. Since no BrokerEvent::Displaced was emitted, attach.rs never forwards Displaced+FIN. O's rc pump therefore remains in raw-mode pump, but receives no PTY Output. This exactly produces the original-stays-attached/stops-rendering symptom.\n\n7. Dual input: O's serve worker has no revocation transition; its local role is still Controller. Input received on O's still-open attach stream calls generic KIND_INPUT. Broker `dispatch_input` does not check that O's brain connection/gen owns the current ControllerSink, so O still writes the PTY. T also writes. Only output/resize broker truth is singular; input authority is split.\n\n8. Later detach/FIN: if O presses ctrl-b d or its process dies, its stream FIN reaches O's serve worker, which calls `detach_session_gen(gen_O)`. `detach_if_gen` sees current gen_T and correctly does not clear T. If T detaches, matching gen_T clears the broker slot and stamps. O does not automatically regain the slot; it remains an output-orphan that can still send generic input until its own stream ends. If a takeover implementation merely FINs O without first delivering Displaced, O's rc pump classifies a post-output EOF as Severed and reconnects, so terminal reason ordering is load-bearing.\n\nWHY DIFFERENT-NODE TAKE USUALLY WORKS, AND ITS RESIDUAL RISK\n\nFor different `by`, Take reaches broker.rs:1335-1347. The broker queues KIND_DISPLACED to O's controller writer, replaces the sink, and returns TookControl. O's writer sends the terminal event; O's serve loop converts it to wire Displaced+FIN; O's pump returns final and prints the loud notice. However the enqueue is `try_send` with ignored failure. A full controller queue or wedged old writer can lose the only revocation signal; replacing the sink still does not directly close/revoke the attach stream. Thus same-node failure is deterministic identity misclassification, while different-node failure remains a backpressure-dependent force-detach weakness.\n\nDETERMINISTIC REGRESSION SEAMS\n\nA. Minimal broker test, adjacent to `same_identity_resubscribe_refuses_a_stale_generation` (`broker.rs:6178`): install A with `(by=node-A, gen=100, Control)`; submit B with `(same by, gen=200, Take)`. Required: B gets TookControl and A receives KIND_DISPLACED. Current code deterministically returns Controller and emits no Displaced. Add the companion `(same by, gen=200, Control)` assertion: BusyControlled, not silent replacement. Preserve `(same by, equal gen=100)` as silent reconstruction and older gen as Busy.\n\nB. Protocol integration, adjacent to `controller_viewer_matrix_and_loud_take` / using the existing loopback seam in `tests/attach.rs`: open two real loopback ConnectionBound attach streams from two operator Brains, serve both with the same proven origin, A Control then B Take. Assert (1) B gets control/output, (2) A decodes AttachRecord::Displaced, then its stream EOFs and A's serve thread returns `AttachServeOutcome::Displaced`, (3) broker retains one controller, (4) post-take A input is rejected/does not echo while B input does. This is the deterministic same-machine reproduction; it avoids CLI timing and exercises the actual attach/FIN pump.\n\nFIX SUGGESTION\n\n1. Make logical viewport ownership `(by, generation-or-durable-stream-token)`, never `by` alone. Equal nonzero token means the exact Request is being re-served after dispatcher/brain reconstruction and may silently retake. Older token is stale and must be Busy. A distinct newer same-node viewport must obey intent: Control→Busy; Take→loud displacement+TookControl. Keep gen=0 legacy behavior for N-1 compatibility. The minimal patch can use existing gen. Stronger correctness replaces wall-ms (two processes can collide within one millisecond) with a broker-authoritative monotonic viewport token—ideally the target broker's durable inbound stream id, which remains equal across redispatch and increases for a new viewport.\n\n2. Factor one loud-take path and invoke it for both different-node Take and same-node/distinct-viewport Take. Do not let identity comparison bypass intent.\n\n3. Make revocation authoritative, not best-effort data queued behind PTY output. Provide a reserved/priority terminal-control lane or explicit serve-worker cancellation keyed by the old viewport token. The old worker must transition Controller→Displaced immediately, stop accepting input, send Displaced to its operator, then FIN. The new controller need not wait for the old terminal to drain, but broker truth must revoke it synchronously.\n\n4. Add broker-side authorization for RC input using the controller connection plus viewport token/generation. `serve_attach` must send an ownership-bearing controller-input request; broker rejects it unless it matches the current ControllerSink. Do not indiscriminately gate all generic InputReq by `is_controller`, because `shellchan` and other system delivery paths intentionally use generic input. Resize already demonstrates the current-controller check pattern.\n\n5. Keep generation-validated detach and stamp convergence. They are correct: an old FIN must not clear the replacement. Persisted `driven_by`/`controlled` remain projections for UI/routing, not controller identity; do not attempt to solve process ownership from those node-level stamps."}}}}],"api":"openai-codex-responses","provider":"openai-codex","model":"gpt-5.6-sol","usage":{"input":376,"output":4522,"cacheRead":177664,"cacheWrite":0,"totalTokens":182562,"reasoningTokens":630,"cost":{"input":0.0018800000000000002,"output":0.13566,"cacheRead":0.088832,"cacheWrite":0,"total":0.226372}},"stopReason":"toolUse","timestamp":1784370345161,"responseId":"resp_0095405da10be5ce016a5b54a95f88819a8e9312ce16ddf0e2","providerPayload":{"type":"openaiResponsesHistory","provider":"openai-codex","dt":true,"items":[{"id":"rs_0095405da10be5ce016a5b54ab7e1c819ab41ce8558b3c622c","type":"reasoning","content":[],"encrypted_content":"gAAAAABqW1S9nsSSHw-7P52JFg7XeUpUB7OjuJHE7QkD5z1rKVXcSuW7TkG_crmvAVOcUy67CFxxIm30rgfRlxJCXclRk2YwRByZINbFvytM5_qB9LETW5gGr4Xia79o4N0FxvsWggLOg4Z0j3dnrQoByB1PAk8BFrGnVKq3sYxV6mdkkfB3djbcZpeeSfrypLuEqZyIMyExTxo3aMVYTD3gdIjoDVKrAHIf8XSHi4PGwLUrO37b0qNda9qJ6z2A6XaBmHZc7ozGs9vEtZJt-4HlNibymukBW3MZJkaze9wyxBGUAyIg6Ey5rfIx8OZktKQPPZ5U5niVzR7cGmT7jg44zXkowP3Qe-cljPICfNNv9FqtoAUWijM3Gokfk8SWZJMJoi7pGC-KIr53pqdhMROyA5Zw8Q-MTVMlkGf-exTwQu7iJWml3ePWQMLytQmyleUSGU60qO2ViZUI1ptgdBusobEhoaxGYB_DMpsSKmHFt8VQR0fk2DiPqjg_SLw0J7_eF_iw9oTrL-pzZTJl7ei3nnxVpswh3HBUK3YD8RrYKtmbPq3swsTgBzhTjT5EtJQ-PVmvxj3SitRgB4Hc1-IfyAvb1KEVv-pkuG13g0vFTv6GChhiOO9zS5IwaUp1BNESs_f_2Yk93x-AgY6iXYgGUkfwB9w3Hv9A38D0_uyQcAFBR2CJWDBkO44l-fNbnmANxtd10GIWrUD87Se3OynphFJg9pxBgi4UXuTS2jh0V5JidgmePI0CFkdNmv_05LYcb6ob5qsdT1_eCwTFE_Ldcfy8F3Ambdv6oM78EvrpmN5fQw5uiWoDiWg04VJPrAnIq7RqLfEhW4MyCfPhJwujFHWIXV0QI7C-iBLGOF3j7phgjQiVxJ5o8w__-VAqVAalC4ltpnI6X2dQEs9FqmbeBVz2V1YUBJQxUDFoLpolPs3Q20debicjE19WIz-bl4L1MSu1iUdE_c3grcPfreru3-qyCoAWURu6Ki2IHRy2Xf4qVXvxDOz6TOzjvbqQt8LQfCx30HbQlD1SZAiH62Oj1zZdzTXZKjk6u7Vp16pDYdJ6ARhi1JlzGkTLwB0iCLuryiXUm_E6DjJVhUiCBfuRoe1_gFiuXhGlmjl1KdrBY8kAq4SE86CI90sZFvb7wqR90Al_YUnpfwMo3_PFImfu43gq-HRIFIYSBSt91wUS_gpKif-fZeH8F0_KkUhTWjLnP4poAgi3xRxGwFWTVufnUUUjNFu5olBaH7Eq-V8A5G47RcUnl8qQVO-ZmfOcCUZXl5LYhal9_69eWSw5cItknqpPVOLRvZE3AhaVfK8V-edm8AKzQ1y_eE35SG4HFxpMadZ5O4HzDk9SQwVGrv6gCtHs2y63dv_DpCEy0HT8yEikZqjnVWTGqOBvtEJ5h-1XJrKMX-wz7KUP60DUwq7K9BRbkNaHzPKNRmJBFmmOXl3s9wZUNj50YnQxQ2nolEmLgc19Kt5kP2s-U5P1W9wFo1G80Q0mIZR8lseoQ-jp8jSIIAI2ZBcWPQlrQq-EAQeAoUtGpNZk4VPqoymb9zO38lRdU7Yp5uTVf0TP4cwaCeZQ1ExzxIAUri56kxZRYn7DSMPSajrbm0qeqPbnbbsZjOu1bgszsIE854PpWnAIvN9nS22uK2PB_vrDAkoSSvgiVD4udDgJZQiwKgSheQtC-VXPFdJd7lpqHmfBRWiYd7caUXtjQ085FuQfXXA9VM01ROcqt0AapOCWun9G0oQc9h5qbZAs1zHz8-d6hKphF4Qg7Kr51O40Own-ea4WiM1KxyCaM2hhC9lgok4vjdjs1KW5gRV27_RuHY5T7O6hnxyNjh-5YvRiJ5yZGfGk2ljY5gxC1k1svJZvfLNjCP8XAvFm7lkeH1llKocplTGUtMdu24K7tZkKuQrwpcm3DaGcc1577bUcvjFPXbFlgyi-11nJ2ajRcOZsV-DVNMuSnNTHmk-ikDHnzYPLOMg4juRjpGApGWxpaw8KL1sW3AYlxhColaGK110wNlgHyKs4CtjA30tr3MO1AtVIe2-C2DGyMk9uGRArwdaCzSbJUFuIeYbA0J8mpn5VrKSIKVvr-XJoggTkF5Nqxz6gkI0s4PhiPwGhU-QN7F4OfFVaFIRnjl-BCBDH3ZN_ni6dwPYJEOh-DUIQf_m3BCogZXjLcWXk42Paq6gR-85Zb_V2HKqX3V4kyNaN1cnmZcVdB4n0j3DNSZq3LzJH8PRn60buM1S-z24IJjU1uLWUEj42QfOg5YVkiwfPyTOLU-9JcjvAjKz-Mnamt1Fl4rA0jMHfpWaxZF-pkf91T-WwcMEnjs5tY3Z8kCTnPULF7-14UwvjjLx4uLZzKGAbYdt1f-7xlMVLxprrJLqMwnBDz0pQOnNxkKjh85AOwDlaOZ_sBtKEuyzclrnv6J4U1Nf_bplMC028z3Gwlor9JCmXnlj5cR7RjuEZLBI3vsMr2Dy1hI26vRLdaciKCva6Kp1nSz-LhPNIQSSaITMqbQ0WkNSnzr9Dg7o7ANCdDqmtIa2hMSFVa4-PrnFRDnhXqOSgx7GIkCQNt6ObEpC_zrDuTWMuK67UyAP_jzvKzPFNpXioPmZA7uwI3ix4dGbKUWkK896Xqkxk15ExG1BiNsJn7yHfpuiinMmqVU2fVDgGnYMkvGurAoIWAqczlRtW89JKIA3EDwsID20dQZChNENxpAjRh7VHqZ5dOMuNaUKc2-ppEhRJXMRZyTSroucJwBxxDJfEZu3RNYssGe0Cv1NboNHqh8z9QW6BvRZt-aVUzrn07mfI8QmMipk8OsXAjsp2YV0va3ISQW_ZdQBVYytV-Y6Lnc6zu8vd21A32J2QbkWrBLFEtaedK8K98uGgkUAdLfu8J814fUnUpU0Wjr2zuBSRIZoLct91fVtUcfVvvdBxM97EFJ3OuYXOBmuQS3MSFOp1zHwDFxGcDluFwYrMo3KM9vJFrHNL_BjIhvZmnhjwINYO0YJCrgZuiZl9urV3ThfBBW1mRcCV4ZUmF9TVg0BjTMSCjqI5Ie4P-W8bMD8E9qxfLduSXvJCbYVTBBDhWFWxBfnX-MrpUHOz-wgtepo64usf5BUlt4VR-LamltEqFkRG0NXM0QpWPqXcB3DfbFvZ6oeKpfCpCDjY_dzNyqTCqf8yTvAkD50wHMDLdpSfHtGVqpJGyw9LAzfX2CYkC4hzgk1J7eaHYV6Df2Q81uzL0dc2W8a2q6ZHz7s0PVGfWLXmcNMlnmT9gQ14f6YVP0pt3xobDaLBM5Yxd5IlMTLYaScOv1p0pudLmfJAXARA5yTpifmdB3F45dGjZwsx35BAvrvf1g9uOLJ4qbz0pqhk72rdJVux1gPRxJ9lBHJyjx37mR3qdO6rgajWWeKKUB6vl61ecOwemM731HIKrbNkAEu-CV1085MXHBQ81a8AXFLeq9m4ejB_sFMkrJIy0OTjq6g9rO2RLR4zoEpCeHyMyGbMvKSfyuxVZH5p_FYyvBGME5-m7-IiiE932mK46Y4MIUNbJSXdxV-4KePkV67slIzDg71yV3iBF5RxUz_VAOK9gCoUeDQtMrwGeB9VNSp_Xi9s47pAYxsX3-tndF2zXz0Zc2uSOpZRKuyOTu9QrT5qCwZiAqjvyVuVIKDG20PjRUzcXpe8Mc-V_2WazGCdSg0deecdNUjgEI6grPHCm1aA3NJINRz7mwVpwJ46tfVx07mKFz8HaWjZoUWjovI3iB3ws0HdbONaWz4-uGN5VhMtwlY3Ltr1LFgcc0qbeSVIhP9OkS0fNKgW9ojSJXJUUwR-z2p9BZDgolJGKrrSlkCNJYZnj9EbTR7dObQVywOGN_hjGraCIQET5pnjhhRnXFuevqeHo67VgXPoQ7loQupi-c5Fis4F9b-xUmxB09w3cGR9AsEzKD17DznlmjOL-Rbnu0tiw77mZ4UQuRK7_JNBo-0Wx94OaGYzbBl7UxijAXKlmA36EHkY9CgyyKgpjGECzqfUN8hYQ6FM9atidGemhyJ1f9tEJKB07hjRv3KUnr3bW38TI-3F5DSPk6a_1qX7vfzfLDdZq_ZoVLbm-Xyvw0DHCm_vikYRZCQsf4961pazVA14i17axPH0P6hdX5bcb_CL7c4fR4OwnxbvVY_2DJHFjU3Gp27EeLQbvKCNXrat_O1Awi1-rA1XjDlEQ124htB11ZbAq8pCAMA6sI9TqNFLc95P2wlCDntaRL5vxVTwH8aqIxkvT_hugw9ks6juGNTFLau6TEsb_dUjsyTEJB4yK4yunnHmxbxVpMujDRH48VkYo_28PjpfLS1-tGFRg2Qos-dEgrfjaCoWGsDFr1mCDq-OYc7DjF30P2xsPF

deterministic for two `rc` processes originating on the same node. `--take` is parsed and transmitted correctly, but broker ownership collapses every operator viewport on a node to the same `by` identity. In `OutputLog::resolve_subscribe` (`crates/spt-daemon/src/broker.rs:1296-1318`), `same_identity` is handled before `AttachIntent`; every equal-or-newer generation silently calls `become_controller` and returns `Controller`. Therefore a same-node `Take` never reaches the only loud-displacement arm at `1335-1347`. `become_controller` drops the incumbent output sink, so the original `rc` immediately stops receiving PTY output, but it does not close the original attach stream or revoke its target-side `serve_attach` worker. No `BrokerEvent::Displaced` is produced, hence no `AttachRecord::Displaced` or FIN reaches the original pump. The new `rc` attaches and renders, while the original process remains alive. More seriously, the original serve worker's local `role` remains `Controller`, and its input path (`attach.rs:470-490`) still calls generic `send_effect_no_ack`; `dispatch_input` (`broker.rs:3920-3988`) does not validate that the sending broker connection is the current controller. Thus broker output-controller truth is singular (the new sink), but both attach workers can still inject keystrokes: the apparent dual controller includes a real dual-input defect.

Subscribed Controller/TookControl sets a worker-local `role=Controller` at 517-528.

Clean operator FIN handling is 580-596: resting Detach first, then generation-validated `detach_session_gen`.

The only `Take`/Displaced arm is restricted to a DIFFERENT remote at 1335-1347. Persisted stamps are node+boolean only (`stamp_driven_by`, 1450-1473), so replacing one same-node viewport with another writes identical `driven_by`/`controlled` values and cannot expose the orphan worker. `detach_if_gen` (1395-1417) correctly prevents the old generation's later FIN from clearing the new slot. `controller_writer` (1671-1773) deliberately drains queued terminal control frames after supersession, but loud displacement is only best-effort: `old.tx.try_send(CtrlMsg::Control(...))` at 1342-1344 ignores Full/Disconnected.

Original CLI O: `spt rc deployah` parses to `AttachIntent::Control` (`cli.rs:1426-1428,1719-1727`). `run_attach_inner` may consult persisted `driven_by` only for Control (`rc.rs:1136-1147`). On the first attach the slot is ordinarily free or held only by the broker's local spawn reader.\\n\\n2. Establish O: `establish_attach` resolves deployah locally first. Local uses the broker loopback connection; remote uses the owner node's QUIC connection. The protocol above the transport leaf is identical. `request_attach_endpoint` opens a ConnectionBound stream and sends `Request{intent:Control,gen:now_ms()}`. For local loopback, the target stream's proven origin is this node's own id; for remote, it is the operator node's handshake id. In both cases two rc processes on the same operator machine have the same `by`.\\n\\n3. Serve O: dispatcher identifies the peer-initiated Attach stream and calls `serve_attach`; `handle_attach_request` calls `Brain::attach_as(session, Control, gen_O, Some(origin))`. The broker resolves O as Controller, installs O's ControllerSink, and stamps `driven_by=origin`, `controlled=true`. O's target serve worker records `role=Controller`; O's operator pump renders Output and sends Input.\\n\\n4. Takeover CLI T: `spt rc deployah --take` maps correctly to Take and bypasses the Control-only persisted-driver refusal. It establishes a second ConnectionBound attach stream with the same `by` and normally `gen_T > gen_O`.\\n\\n5. Defective broker transition: `resolve_subscribe` sees `controller_by()==by` and enters `same_identity` before looking at Take. Because `gen_T` is not older, it calls `become_controller`, returns ordinary `Controller`, and never executes the loud Take arm. Broker truth now has exactly one ControllerSink: T. `become_controller` drops O's sink/writer path and installs T's, so all new PTY Output goes to T. Persisted stamps remain `driven_by=the same node`, `controlled=true`; no durable projection changes.\\n\\n6. Orphan O: dropping O's ControllerSink is not equivalent to detaching O's attach protocol. O's operator connection is alive, so ConnectionBound does not synthesize FIN. O's target-side attach stream subscription and `serve_attach` loop remain alive. Since no BrokerEvent::Displaced was emitted, attach.rs never forwards Displaced+FIN. O's rc pump therefore remains in raw-mode pump, but receives no PTY Output. This exactly produces the original-stays-attached/stops-rendering symptom.\\n\\n7. Dual input: O's serve worker has no revocation transition; its local role is still Controller. Input received on O's still-open attach stream calls generic KIND_INPUT. Broker `dispatch_input` does not check that O's brain connection/gen owns the current ControllerSink, so O still writes the PTY. T also writes. Only output/resize broker truth is singular; input authority is split.\\n\\n8. Later detach/FIN: if O presses ctrl-b d or its process dies, its stream FIN reaches O's serve worker, which calls `detach_session_gen(gen_O)`. `detach_if_gen` sees current gen_T and correctly does not clear T. If T detaches, matching gen_T clears the broker slot and stamps. O does not automatically regain the slot; it remains an output-orphan that can still send generic input until its own stream ends. If a takeover implementation merely FINs O without first delivering Displaced, O's rc pump classifies a post-output EOF as Severed and reconnects, so terminal reason ordering is load-bearing.\\n\\nWHY DIFFERENT-NODE TAKE USUALLY WORKS, AND ITS RESIDUAL RISK\\n\\nFor different `by`, Take reaches broker.rs:1335-1347. The broker queues KIND_DISPLACED to O's controller writer, replaces the sink, and returns TookControl. O's writer sends the terminal event; O's serve loop converts it to wire Displaced+FIN; O's pump returns final and prints the loud notice. However the enqueue is `try_send` with ignored failure. A full controller queue or wedged old writer can lose the only revocation signal; replacing the sink still does not directly close/revoke the attach stream. Thus same-node failure is deterministic identity misclassification, while different-node failure remains a backpressure-dependent force-detach weakness.\\n\\nDETERMINISTIC REGRESSION SEAMS\\n\\nA. Minimal broker test, adjacent to `same_identity_resubscribe_refuses_a_stale_generation` (`broker.rs:6178`): install A with `(by=node-A, gen=100, Control)`; submit B with `(same by, gen=200, Take)`. Required: B gets TookControl and A receives KIND_DISPLACED. Current code deterministically returns Controller and emits no Displaced. Add the companion `(same by, gen=200, Control)` assertion: BusyControlled, not silent replacement. Preserve `(same by, equal gen=100)` as silent reconstruction and older gen as Busy.\\n\\nB. Protocol integration, adjacent to `controller_viewer_matrix_and_loud_take` / using the existing loopback seam in `tests/attach.rs`: open two real loopback ConnectionBound attach streams from two operator Brains, serve both with the same proven origin, A Control then B Take. Assert (1) B gets control/output, (2) A decodes AttachRecord::Displaced, then its stream EOFs and A's serve thread returns `AttachServeOutcome::Displaced`, (3) broker retains one controller, (4) post-take A input is rejected/does not echo while B input does. This is the deterministic same-machine reproduction; it avoids CLI timing and exercises the actual attach/FIN pump.\\n\\nFIX SUGGESTION\\n\\n1. Make logical viewport ownership `(by, generation-or-durable-stream-token)`, never `by` alone. Equal nonzero token means the exact Request is being re-served after dispatcher/brain reconstruction and may silently retake. Older token is stale and must be Busy. A distinct newer same-node viewport must obey intent: Control→Busy; Take→loud displacement+TookControl. Keep gen=0 legacy behavior for N-1 compatibility. The minimal patch can use existing gen. Stronger correctness replaces wall-ms (two processes can collide within one millisecond) with a broker-authoritative monotonic viewport token—ideally the target broker's durable inbound stream id, which remains equal across redispatch and increases for a new viewport.\\n\\n2. Factor one loud-take path and invoke it for both different-node Take and same-node/distinct-viewport Take. Do not let identity comparison bypass intent.\\n\\n3. Make revocation authoritative, not best-effort data queued behind PTY output. Provide a reserved/priority terminal-control lane or explicit serve-worker cancellation keyed by the old viewport token. The old worker must transition Controller→Displaced immediately, stop accepting input, send Displaced to its operator, then FIN. The new controller need not wait for the old terminal to drain, but broker truth must revoke it synchronously.\\n\\n4. Add broker-side authorization for RC input using the controller connection plus viewport token/generation. `serve_attach` must send an ownership-bearing controller-input request; broker rejects it unless it matches the current ControllerSink. Do not indiscriminately gate all generic InputReq by `is_controller`, because `shellchan` and other system delivery paths intentionally use generic input. Resize already demonstrates the current-controller check pattern.\\n\\n5. Keep generation-validated detach and stamp convergence. They are correct: an old FIN must not clear the replacement. Persisted `driven_by`/`controlled` remain projections for UI/routing, not controller identity; do not attempt to solve process ownership from those node-level stamps.\"}}}","call_id":"call_Hw20Ty8NbqvpyYMGvxFW30oa","name":"yield"}]},"duration":140834.92440000176,"ttft":2502.983799993992,"contextSnapshot":{"promptTokens":178040,"nonMessageTokens":15565}}}

Therefore a same-node `Take` never reaches the only loud-displacement arm at `1335-1347`. `become_controller` drops the incumbent output sink, so the original `rc` immediately stops receiving PTY output, but it does not close the original attach stream or revoke its target-side `serve_attach` worker. No `BrokerEvent::Displaced` is produced, hence no `AttachRecord::Displaced` or FIN reaches the original pump. The new `rc` attaches and renders, while the original process remains alive.

On the first attach the slot is ordinarily free or held only by the broker's local spawn reader.\n\n2. Establish O: `establish_attach` resolves deployah locally first. Local uses the broker loopback connection; remote uses the owner node's QUIC connection. The protocol above the transport leaf is identical. `request_attach_endpoint` opens a ConnectionBound stream and sends `Request{intent:Control,gen:now_ms()}`. For local loopback, the target stream's proven origin is this node's own id; for remote, it is the operator node's handshake id. In both cases two rc processes on the same operator machine have the same `by`.\n\n3. Serve O: dispatcher identifies the peer-initiated Attach stream and calls `serve_attach`; `handle_attach_request` calls `Brain::attach_as(session, Control, gen_O, Some(origin))`. The broker resolves O as Controller, installs O's ControllerSink, and stamps `driven_by=origin`, `controlled=true`. O's target serve worker records `role=Controller`; O's operator pump renders Output and sends Input.\n\n4. Takeover CLI T: `spt rc deployah --take` maps correctly to Take and bypasses the Control-only persisted-driver refusal. It establishes a second ConnectionBound attach stream with the same `by` and normally `gen_T > gen_O`.\n\n5. Defective broker transition: `resolve_subscribe` sees `controller_by()==by` and enters `same_identity` before looking at Take. Because `gen_T` is not older, it calls `become_controller`, returns ordinary `Controller`, and never executes the loud Take arm. Broker truth now has exactly one ControllerSink: T. `become_controller` drops O's sink/writer path and installs T's, so all new PTY Output goes to T.

O's operator connection is alive, so ConnectionBound does not synthesize FIN. O's target-side attach stream subscription and `serve_attach` loop remain alive.

Only output/resize broker truth is singular; input authority is split.\n\n8. Later detach/FIN: if O presses ctrl-b d or its process dies, its stream FIN reaches O's serve worker, which calls `detach_session_gen(gen_O)`. `detach_if_gen` sees current gen_T and correctly does not clear T. If T detaches, matching gen_T clears the broker slot and stamps. O does not automatically regain the slot; it remains an output-orphan that can still send generic input until its own stream ends. If a takeover implementation merely FINs O without first delivering Displaced, O's rc pump classifies a post-output EOF as Severed and reconnects, so terminal reason ordering is load-bearing.\n\nWHY DIFFERENT-NODE TAKE USUALLY WORKS, AND ITS RESIDUAL RISK\n\nFor different `by`, Take reaches broker.rs:1335-1347. The broker queues KIND_DISPLACED to O's controller writer, replaces the sink, and returns TookControl.

T from the same machine sends Take with the same `by` and newer `gen=T`. Broker's same-identity branch silently calls `become_controller`, returns Controller, drops O's output sink, installs T, and rewrites identical persisted stamps. O's ConnectionBound attach stream stays open because O's process/connection is alive. O's serve worker receives no BrokerEvent::Displaced, so it emits neither AttachRecord::Displaced nor FIN; O stops rendering but remains pumping. O's worker-local role remains Controller and generic InputReq has no current-owner token, so O and T can both type. O's later FIN carries old gen and correctly cannot clear T; T's matching FIN clears the slot.\n\nDeterministic red seam: broker test A=`Control(by=node-A,gen=100)`, B=`Take(by=node-A,gen=200)`. Required B outcome TookControl plus A Displaced; current outcome is Controller and no notice. Companion asserts newer same-node Control is Busy. Full loopback regression should open two real ConnectionBound streams under the same proven origin and assert A receives Displaced+EOF/server outcome Displaced, B alone renders, and A post-take input cannot reach the PTY.\n\nFix: controller identity is logical viewport `(by, token)`, not node. Equal nonzero token is the exact Request re-served and may silently reconstruct; older is stale/Busy; a distinct newer same-node viewport obeys intent—Control Busy, Take loud displacement. Preserve gen0 N-1 behavior. Prefer a broker-authoritative monotonic durable stream/viewport token over collision-prone wall-ms. Route displacement over a priority/authoritative revocation lane rather than ignored `try_send`; synchronously revoke old input authority, then deliver Displaced and FIN. Add a token-bearing RC controller-input request (or dedicated guarded RC-input verb) validated against the current ControllerSink. Do not globally gate generic KIND_INPUT because shell/system delivery uses it. Keep generation-validated detach and stamp convergence unchanged."},"status":"success","type":"result"},"isError":false,"timestamp":1784370552407}}
