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.

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: **PTY 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 spt-hosted Claude Code settings TUI corruption from supplied screenshot: row immediately above `Search settings...` is shifted left two columns; scrap fragments `To`, `Wh`, `Es` remain in left margin; rc identity banner at bottom. Find exact source seam and report only.\n# Constraints\nRead-only. Skip edits, formatters, linters, and project-wide tests. Current tree is v0.38.x main. Use CONTEXT/ADR/Known Hazards semantics. Return exact files/symbols/lines and deterministic regression.\n# Contract\nSeparate child TUI output, server ScreenGrid/repaint, rc status overlay/PTY resize, terminal emulator behavior, and final-output ordering.\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 `SettingsProtocolRca`. Currently visible peers:\n- `Main` — main (main, running)\n- `RefreshLifecycle` — Daemon Lifecycle Investigator (sub, parked)\n- `PtyControl` — PTY Transport Investigator (sub, parked)\n- `ReproHarness` — Integration Test Investigator (sub, parked)\n- `HyphenMessage` — CLI Parsing Investigator (sub, parked)\n- `ElevatedRc` — Remote Control Investigator (sub, parked)\n- `ElevatedMessaging` — Messaging Lifecycle Investigator (sub, parked)\n- `RcSplitBrain` — Registry Session Investigator (sub, parked)\n- `ElevatedHosted` — Windows Token Investigator (sub, parked)\n- `ShortformDifferential` — Delivery Differential Investigator (sub, parked)\n- `AdapterFreshSemantics` — Claude Adapter Investigator (sub, parked)\n- `PerriDurableState` — State Forensics Investigator (sub, parked)\n- `CoreFreshSemantics` — Core Lifecycle Investigator (sub, parked)\n- `RestStateRca` — Endpoint Lifecycle Investigator (sub, parked)\n- `CreateNoopRca` — CLI Semantics Investigator (sub, parked)\n- `ControlledStampRca` — Broker Control-State Investigator (sub, parked)\n- `EmphRestartRca` — Daemon Restart Investigator (sub, parked)\n- `HarnessExitRca` — Harness Lifecycle Investigator (sub, parked)\n- `V034DiffRca` — Regression Archaeologist (sub, parked)\n- `V034ReleaseRca` — Release Contract Investigator (sub, parked)\n- `LiveLogRca` — Runtime Telemetry Investigator (sub, parked)\n- `PtyPathRca` — PTY Concurrency Investigator (sub, parked)\n- `BrokerCpuRca` — Broker Concurrency Investigator (sub, parked)\n- `RedispatchCpuRca` — Release Regression Investigator (sub, parked)\n- `BrainCpuRca` — Brain Performance Investigator (sub, parked)\n- `ResidualBrainCpu` — Performance Regression Investigator (sub, parked)\n- `AdapterIdentityDiff` — Adapter Lifecycle Investigator (sub, parked)\n- `CoreSeedBoundary` — Core Security Reviewer (sub, parked)\n- `HerdrTerminalResearch` — Open-source Terminal Librarian (sub, parked)\n- `PickerWhitespaceRca` — Terminal TUI Investigator (sub, parked)\n- `RcWhitespaceRca` — PTY Protocol Investigator (sub, parked)\n- `RcTakeoverRca` — RC Protocol Investigator (sub, parked)\n- `BrokerTakeoverRca` — Broker Concurrency Investigator (sub, parked)\n- `TodlandoSessionRca` — Lifecycle Investigator (sub, parked)\n- `DuplicatePumpRca` — IPC Diagnostics Investigator (sub, parked)\n- `RcSettingsOverlayRca` — Terminal Overlay Investigator (sub, running)\n- `GridSettingsRca` — VT State-Machine Investigator (sub, running)\nIdle/parked peers are not gone: messaging them wakes (or revives) them.\n\nUse `irc` only for quick coordination, never long-form content. Address peers by id or use `\"all\"` to broadcast.\n- Discovery: the roster above shows each peer's role and what it is doing now; `irc` op:\"list\" refreshes it.\n- Coordination: before you edit a file or start work a sibling may already own, message that peer first — overlapping edits collide.\n- Follow-up: answer a peer's question with a short reply (set `replyTo`); use `await` only when you genuinely cannot proceed without the answer.\n\nCOMPLETION\n===================================\n\nNo TODO tracking, no progress updates. Execute; report results with `yield`.\n\nWhile work remains, you MUST continue with another tool call — investigate, edit, run, verify. Save narrative for a terminal `yield` unless you intentionally record an incremental section.\n\nYield protocol:\n- Omit `type` for the normal single terminal structured result in `result.data`.\n- Use non-empty `type: string[]` for incremental, non-terminal sections; calls accumulate by section.\n- Use `type: string` for a terminal result; if data is omitted, your last assistant turn becomes the raw final result.\n\nThis is your only way to return a final result. For structured results, you NEVER put JSON in plain text or substitute a text summary for `result.data`.\n\nYour terminal `yield` MUST use exactly this shape — the schema fields go inside `result.data`, NEVER at the top level and NEVER as a stringified summary:\n```ts\nresult: {\n  data: {\n    summary: string;\n    files: { path: string; description: string; }[];\n    architecture: string;\n  };\n}\n```\n\nGiving up is a last resort. If truly blocked, you MUST terminal-yield `result.error` describing what you tried and the exact blocker.\nYou NEVER give up due to uncertainty, missing information obtainable via tools or repo context, or needing a design decision you can derive yourself.\n\nYou MUST keep going until this ticket is closed. This matters.\n\nPROJECT\n===================================\n\n<workstation>\n- OS: win32 10.0.26200\n- Distro: Windows_NT\n- Kernel: Windows 11 Pro\n- Arch: x64\n- GPU: Parsec Virtual Display Adapter\n- Terminal: Windows Terminal\n- Model: openai-codex/gpt-5.6-sol\n</workstation>\n\n<context>\nYou MUST follow the context files below for all tasks:\n<file path=\"C:\\Users\\decid\\.claude\\CLAUDE.md\">\n## Reference Documents\n\nThe `~/.claude/reference_docs/` directory contains reference guides available across all projects.\n\n- **[claude-code-hooks.md](reference_docs/claude-code-hooks.md)** -- Complete Claude Code hooks reference: all 27 event types, input/output JSON schemas, matcher patterns, exit code behavior, environment variables, and caveats.

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. Don't block on it — proceed with your ranking if the user is AFK.\n\n## Phase 4 — Instrument\n\nEach probe must map to a specific prediction from Phase 3. **Change one variable at a time.**\n\nTool preference:\n\n1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.\n2. **Targeted logs** at the boundaries that distinguish hypotheses.\n3. Never \"log everything and grep\".\n\n**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.\n\n**Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.\n\n## Phase 5 — Fix + regression test\n\nWrite the regression test **before the fix** — but only if there is a **correct seam** for it.\n\nA correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site. If the only available seam is too shallow (single-caller test when the bug needs multiple callers, unit test that can't replicate the chain that triggered the bug), a regression test there gives false confidence.\n\n**If no correct seam exists, that itself is the finding.** Note it. The codebase architecture is preventing the bug from being locked down. Flag this for the next phase.\n\nIf a correct seam exists:\n\n1. Turn the minimised repro into a failing test at that seam.\n2. Watch it fail.\n3. Apply the fix.\n4. Watch it pass.\n5. Re-run the Phase 1 feedback loop against the original (un-minimised) scenario.\n\n## Phase 6 — Cleanup + post-mortem\n\nRequired before declaring done:\n\n- [ ] Original repro no longer reproduces (re-run the Phase 1 loop)\n- [ ] Regression test passes (or absence of seam is documented)\n- [ ] All `[DEBUG-...]` instrumentation removed (`grep` the prefix)\n- [ ] Throwaway prototypes deleted (or moved to a clearly-marked debug location)\n- [ ] The hypothesis that turned out correct is stated in the commit / PR message — so the next debugger learns\n\n**Then ask: what would have prevented this bug?** If the answer involves architectural change (no good test seam, tangled callers, hidden coupling) hand off to the `/improve-codebase-architecture` skill with the specifics. Make the recommendation **after** the fix is in, not before — you have more information now than when you started.\n"}],"details":{"resolvedPath":"C:\\Users\\decid\\.claude\\skills\\diagnose\\SKILL.md","contentType":"text/markdown","displayContent":{"text":"---\r\nname: diagnose\r\ndescription: Disciplined diagnosis loop for hard bugs and performance regressions.

VT output is also enabled defensively on legacy Windows consoles.\n 729|- **`spt rc` to a live local endpoint no longer times out with `brain IPC read deadline elapsed` after a self-update.** A single panic while the broker's effect journal was locked could poison it and brick every subsequent attach; the journal now recovers from a poisoned lock, and the loopback attach path fails fast with a real error instead of an opaque 10-second deadline.\n 730|- **`spt send` across nodes no longer reports `SENT(WAN)` when nothing was delivered.** A cross-node send was a fire-and-forget local buffer write — a refused or no-perch delivery was silently dropped while the sender printed success. The receiver now writes the delivery outcome back and the sender waits for it, so a real failure prints an honest line; the dial also tries the last-known direct address first (mirroring the gossip path) instead of forcing a cold discovery on every send.\n 731|- **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`.

Wire / transport\n…\n### 4.5 Inbox legacy compat must not double-deliver\n- **Failure:** message surfaced via both spool (durable) and legacy inbox files → duplicate or racing delivery.\n…\n- **Sister cite:** `src/common/inbox.rs`.\n\n### 4.6 Addressable-id charset reserves the address delimiters\n<!-- [doc->REQ-HAZARD-ID-CHARSET] -->\n- **Failure:** a bare endpoint id that contains `:` or `@` (or a path separator / whitespace / control char) makes the canonical qualified address `[subnet:]id[@node]` (ADR-0006 / REQ-INST-10) ambiguous to parse, and lets a name smuggle into a perch directory path. Once permissive ids exist in the wild, tightening later needs a migration.\n- **Invariant:** every addressable id/name is validated to `[A-Za-z0-9_-]` + Hiragana/Katakana/CJK only, length `1..=64`, **at every creation seam** (`ready` start, `api bind`, `api listen`, `api worker-start`). `:` and `@` are permanently reserved as address delimiters; reads of existing perches are never re-validated. Enforce now (pre-M3/M4) so no permissive id-data accumulates.\n- **spt-core mapping:** `spt_proto::id::validate_endpoint_id`; called at the four creation seams. The existing Psyche (`<parent>-psyche`) / Worker (`<parent>-w<N>`) suffix scheme uses only `-` + alphanumerics, so composite ids validate.\n\n### 4.7 Concurrent SQLite openers must not fail with \"database is locked\"\n<!-- [doc->REQ-HAZARD-REGISTRY-CONCURRENT] -->\n- **Failure:** two endpoints on one machine open the same SQLite store at once (e.g. two `ReadyAgent::start` calls registering simultaneously) and one fails outright with `SQLITE_BUSY` / \"database is locked\" → spurious registration/spool failure. Surfaced as a parallel-test flake in `two_agents_exchange_message_tcp_and_spool`, but the bug is real concurrency, not test-only.\n- **Invariant:** `busy_timeout` is set **before** any lock-taking statement on every connection. Switching `journal_mode=WAL` takes a brief exclusive lock; with the default 0ms timeout it fails immediately under contention, so the pragma order is load-bearing: `Connection::open` → `busy_timeout` → `journal_mode=WAL` → `CREATE TABLE …`. WAL alone is insufficient (concurrent *writers* still serialize; they must *wait*, not error).\n- **spt-core mapping:** `spt_store::registry::open_registry` + `spt_store::spool::open_spool_at`; both set `busy_timeout=5000` first. Any future SQLite store (history Path B, instance registry) must follow the same ordering.\n\n### 4.8 Registry merge ordered by epoch, never wall-clock (red-team #8)\n<!-- [doc->REQ-HAZARD-REGISTRY-EPOCH-LEASE] -->\n- **Failure:** the per-subnet registry replicates `endpoint_id → [instances]` eventually-consistently across nodes. Under a partition or clock skew, a lagging node re-announces a stale `Active` for an endpoint that has actually gone `Offline`. If the merge ordered updates by wall-clock (or \"last write wins\"), the stale `Active` overwrites the newer `Offline` and resolution routes a message to a dead/wrong instance.\n- **Invariant:** the merge precedence key is a **per-node monotonic epoch counter** (`spt_store::epoch::EpochSource`, persisted, strictly increasing, NEVER wall-clock), compared version-vector style per `(endpoint_id, node)`: an incoming update wins **iff its epoch is strictly greater** than the stored one for that node; equal or lower is dropped as stale. So a newer `Offline` (higher epoch) can never be clobbered by a lagging `Active` (lower epoch), and an idempotent equal-epoch replay is a no-op. Wall-clock is at most a human tiebreaker hint inside a flagged conflict, never the ordering authority. The same epoch source unifies with the D6 sync-precedence concurrent-write detection (#7).\n- **spt-core mapping:** `spt_net::net::registry::SubnetRegistry::merge_instance` (the lease) + `spt_store::epoch::EpochSource` (the counter). Cross-node replication of the merge wires at D4; the merge seam is identical for local and wire-delivered updates. Chaos/two-host verification = D9.\n\n### 4.9 SQLite stores must create their parent dir — SQLite won't\n<!-- [doc->REQ-HAZARD-REGISTRY-DIR-CREATE] -->\n- **Failure:** `Connection::open` creates the database FILE but never its parent DIRECTORY. On a fresh home (first boot, fresh CI `_work` dir) a registry op that runs before any perch-creating op (`create_dir_all` side effects) fails `SQLITE_CANTOPEN` — \"unable to open database file …owlery\\.registry\". Timing-dependent: whichever code path touches the home first decides the outcome, so it surfaces as a parallel-test flake (bind-first tests losing the dir-creation race to perch-first tests). Bit the hfenduleam CI leg twice (2026-06-03/04, four spt-msg unit tests at once on the second strike) before being run to ground; a slow runner filesystem (AV scanning fresh dirs) widens the window but is not the cause.\n- **Invariant:** every SQLite store's open path `create_dir_all`s its parent dir itself, best-effort, before `Connection::open` — never relying on another subsystem having materialized the home first. (Mirrors the spool, which always did this; the registry didn't.)\n- **spt-core mapping:** `spt_store::registry::open_registry` (`create_dir_all(owlery)` before open). `spt_store::spool::open_spool_at` already creates its perch dir. Any future SQLite store must do the same — pair this with the 4.7 pragma ordering on every new store.\n\n### 4.10 Dead node identities leave immortal registry rows  `[REQ-HAZARD-REGISTRY-GHOST-ROWS]`\n<!-- [doc->REQ-HAZARD-REGISTRY-GHOST-ROWS] -->\n- **Failure:** the registry's only superseding mechanism is the per-`(endpoint_id, node)` epoch lease (4.8) — a row is replaced only by a newer row *from the same node*. When a node identity dies permanently (machine retired, or `node.key` regenerated so the \"node\" never speaks again), its rows are never superseded and never expire: they sit in the in-memory registries and the `identity/registry/<subnet>.json` snapshots forever. A bare-id send then resolves the same endpoint id on both the live and the dead identity and refuses with a **phantom `AcrossNodes` ambiguity** — unfixable by the user, because no qualifier reaches a node that no longer exists. Hit live in the M7 acceptance run (2026-06-06): gravity paired under two identities (09ef…, then 03854a… af…\n- **Invariant:** registry rows authored by a **silent** peer node decay: a node not *heard* (admitted inbound feed — the M7 D2 heard-map, REQ-SUBNET-1) within the eviction window (`registry_evict_after_ms`, default 300s ≈ 10 default pump cadences) has its rows **evicted** from every subnet registry, snapshots rewritten. Own rows never decay (the node always hears itself implicitly — it authors them each pump tick). Eviction is safe under the lease: v1 has **no transitive gossip**, so any future update for a node comes from that node itself, alive, re-inserting from its durable `EpochSource` within one cadence — there is no lagging third-party replay to mis-order against. A merely-offline node loses its rows after the window and reconverges on return; meanwhi…\n- **spt-core mapping:** `spt_net::net::registry::SubnetRegistry::evict_nodes` (model) + `spt_daemon::registryhost::RegistryHost::evict_silent_peers` (heard-map TTL) driven from the registry pump tick (`peerloop`). Trust rows are NOT auto-evicted (trust is a user decision; a stale trust row only costs dead dials) — pruning those is a separate verb.\n- **Source:** M7 acceptance run 2026-06-06 (DEFERRED.md \"Ghost registry row eviction\"); the AMBIGUOUS render fix rode along.\n- **Mesh note (ADR-0017, 2026-06-08):** the subnet mesh **preserves** this invariant rather than superseding it. \"No transitive gossip\" sharpens to **no transitive *row* gossip** — the mesh relays only the member *roster* (discovery), while registry **rows stay own-authored and are fetched directly** from each member over a handshake. So \"any future update for a node comes from that node itself, alive\" still holds and the eviction lease is untouched. (The plan's rejected alternative — signed transitive *row* relay — would have broken this; roster-only relay was chosen precisely to keep it.)\n\n### 4.11 Advertisement-epoch reset strands a node  `[REQ-HAZARD-EPOCH-RESET]`\n<!-- [doc->REQ-HAZARD-EPOCH-RESET] -->\n- **Failure:** a node whose advertisement-epoch counter resets (the durable `EpochSource` file lost/recreated) re-advertises with LOW epochs; peers hold a higher last-seen epoch for that `(endpoint, node)` lease and drop every fresh row as **stale** — the node advertises into a void until its counter outruns its own history.

Once permissive ids exist in the wild, tightening later needs a migration.\n- **Invariant:** every addressable id/name is validated to `[A-Za-z0-9_-]` + Hiragana/Katakana/CJK only, length `1..=64`, **at every creation seam** (`ready` start, `api bind`, `api listen`, `api worker-start`). `:` and `@` are permanently reserved as address delimiters; reads of existing perches are never re-validated. Enforce now (pre-M3/M4) so no permissive id-data accumulates.\n- **spt-core mapping:** `spt_proto::id::validate_endpoint_id`; called at the four creation seams.

Surfaced as a parallel-test flake in `two_agents_exchange_message_tcp_and_spool`, but the bug is real concurrency, not test-only.\n- **Invariant:** `busy_timeout` is set **before** any lock-taking statement on every connection. Switching `journal_mode=WAL` takes a brief exclusive lock; with the default 0ms timeout it fails immediately under contention, so the pragma order is load-bearing: `Connection::open` → `busy_timeout` → `journal_mode=WAL` → `CREATE TABLE …`. WAL alone is insufficient (concurrent *writers* still serialize; they must *wait*, not error).\n- **spt-core mapping:** `spt_store::registry::open_registry` + `spt_store::spool::open_spool_at`; both set `busy_timeout=5000` first.

Under a partition or clock skew, a lagging node re-announces a stale `Active` for an endpoint that has actually gone `Offline`. If the merge ordered updates by wall-clock (or \"last write wins\"), the stale `Active` overwrites the newer `Offline` and resolution routes a message to a dead/wrong instance.\n- **Invariant:** the merge precedence key is a **per-node monotonic epoch counter** (`spt_store::epoch::EpochSource`, persisted, strictly increasing, NEVER wall-clock), compared version-vector style per `(endpoint_id, node)`: an incoming update wins **iff its epoch is strictly greater** than the stored one for that node; equal or lower is dropped as stale. So a newer `Offline` (higher epoch) can never be clobbered by a lagging `Active` (lower epoch), and an idempotent equal-epoch replay is a no-op. Wall-clock is at most a human tiebreaker hint inside a flagged conflict, never the ordering authority. The same epoch source unifies with the D6 sync-precedence concurrent-write detection (#7).\n- **spt-core mapping:** `spt_net::net::registry::SubnetRegistry::merge_instance` (the lease) + `spt_store::epoch::EpochSource` (the counter). Cross-node replication of the merge wires at D4; the merge seam is identical for local and wire-delivered updates. Chaos/two-host verification = D9.\n\n### 4.9 SQLite stores must create their parent dir — SQLite won't\n<!-- [doc->REQ-HAZARD-REGISTRY-DIR-CREATE] -->\n- **Failure:** `Connection::open` creates the database FILE but never its parent DIRECTORY. On a fresh home (first boot, fresh CI `_work` dir) a registry op that runs before any perch-creating op (`create_dir_all` side effects) fails `SQLITE_CANTOPEN` — \"unable to open database file …owlery\\.registry\". Timing-dependent: whichever code path touches the home first decides the outcome, so it surfaces as a parallel-test flake (bind-first tests losing the dir-creation race to perch-first tests). Bit the hfenduleam CI leg twice (2026-06-03/04, four spt-msg unit tests at once on the second strike) before being run to ground; a slow runner filesystem (AV scanning fresh dirs) widens the window but is not the cause.\n- **Invariant:** every SQLite store's open path `create_dir_all`s its parent dir itself, best-effort, before `Connection::open` — never relying on another subsystem having materialized the home first. (Mirrors the spool, which always did this; the registry didn't.)\n- **spt-core mapping:** `spt_store::registry::open_registry` (`create_dir_all(owlery)` before open). `spt_store::spool::open_spool_at` already creates its perch dir. Any future SQLite store must do the same — pair this with the 4.7 pragma ordering on every new store.\n\n### 4.10 Dead node identities leave immortal registry rows  `[REQ-HAZARD-REGISTRY-GHOST-ROWS]`\n<!-- [doc->REQ-HAZARD-REGISTRY-GHOST-ROWS] -->\n- **Failure:** the registry's only superseding mechanism is the per-`(endpoint_id, node)` epoch lease (4.8) — a row is replaced only by a newer row *from the same node*. When a node identity dies permanently (machine retired, or `node.key` regenerated so the \"node\" never speaks again), its rows are never superseded and never expire: they sit in the in-memory registries and the `identity/registry/<subnet>.json` snapshots forever. A bare-id send then resolves the same endpoint id on both the live and the dead identity and refuses with a **phantom `AcrossNodes` ambiguity** — unfixable by the user, because no qualifier reaches a node that no longer exists. Hit live in the M7 acceptance run (2026-06-06): gravity paired under two identities (09ef…, then 03854a… af…\n- **Invariant:** registry rows authored by a **silent** peer node decay: a node not *heard* (admitted inbound feed — the M7 D2 heard-map, REQ-SUBNET-1) within the eviction window (`registry_evict_after_ms`, default 300s ≈ 10 default pump cadences) has its rows **evicted** from every subnet registry, snapshots rewritten. Own rows never decay (the node always hears itself implicitly — it authors them each pump tick). Eviction is safe under the lease: v1 has **no transitive gossip**, so any future update for a node comes from that node itself, alive, re-inserting from its durable `EpochSource` within one cadence — there is no lagging third-party replay to mis-order against. A merely-offline node loses its rows after the window and reconverges on return; meanwhi…\n- **spt-core mapping:** `spt_net::net::registry::SubnetRegistry::evict_nodes` (model) + `spt_daemon::registryhost::RegistryHost::evict_silent_peers` (heard-map TTL) driven from the registry pump tick (`peerloop`). Trust rows are NOT auto-evicted (trust is a user decision; a stale trust row only costs dead dials) — pruning those is a separate verb.\n- **Source:** M7 acceptance run 2026-06-06 (DEFERRED.md \"Ghost registry row eviction\"); the AMBIGUOUS render fix rode along.\n- **Mesh note (ADR-0017, 2026-06-08):** the subnet mesh **preserves** this invariant rather than superseding it. \"No transitive gossip\" sharpens to **no transitive *row* gossip** — the mesh relays only the member *roster* (discovery), while registry **rows stay own-authored and are fetched directly** from each member over a handshake. So \"any future update for a node comes from that node itself, alive\" still holds and the eviction lease is untouched. (The plan's rejected alternative — signed transitive *row* relay — would have broken this; roster-only relay was chosen precisely to keep it.)\n\n### 4.11 Advertisement-epoch reset strands a node  `[REQ-HAZARD-EPOCH-RESET]`\n<!-- [doc->REQ-HAZARD-EPOCH-RESET] -->\n- **Failure:** a node whose advertisement-epoch counter resets (the durable `EpochSource` file lost/recreated) re-advertises with LOW epochs; peers hold a higher last-seen epoch for that `(endpoint, node)` lease and drop every fresh row as **stale** — the node advertises into a void until its counter outruns its own history. Nothing renders the cause: the node looks healthy locally, peers simply never update.\n- **Invariant (mitigation by construction, common case):** the common trigger — a full reinstall / identity regeneration — is covered by the **re-pair trust overwrite** (M8 decision 13, REQ-SUBNET-7): a completed ceremony presenting the same label + machine id evicts the superseded identity's trust AND registry rows on the seed-holder, and the peer-side epoch memory **dies with the deleted row** — the re-paired node's fresh epochs land on a clean lease.

Field shape: the 60s sync pump's two git calls (`for-each-ref` + `rev-parse`) flashed two blank windows per minute on the user's desktop (2026-06-06).\n- **Invariant:** every short-lived console child spawned from daemon-reachable code sets `creation_flags(0x0800_0000)` (`CREATE_NO_WINDOW`). Long-lived detached children use `detached_no_inherit` (already `DETACHED_PROCESS | CREATE_NO_WINDOW`); de-elevated spawns use `CREATE_NEW_CONSOLE + SW_HIDE` (5.7 — `CreateProcessWithTokenW` rejects `CREATE_NO_WINDOW`, error 87).\n- **Test seam caveat:** window-absence is unobservable from a consoled test runner — the child inherits the runner's console and never creates a window, flag or no flag. Unit coverage asserts the flagged spawn still works (the error-87 \"flag combo breaks spawn\" regression class); window-absence was verified live by process-watch capture.\n- **spt-core mapping:** `spt-store::gitrun::run_git` (every BranchStore/ContextStore git call), `spt-daemon::shellhost::kill_shell_pid` (taskkill), `spt-runtime::run_bounded_command` (manifest hook commands), `spt-runtime::ManifestRuntime::command_for` (the one shared builder behind `spawn_session` + `run_bounded_stdin` — the notif pump's `spawn_notif_command` and the live agent's psyche/echo/turn spawns), `spt-daemon::shellwake` (already guarded). The flag lives in each shared builder, not per call site, so the invariant holds for every ManifestRuntime spawn by construction.\n- **Source:** spt-core field bug, 2026-06-06 — two blank windows flashing every 60 seconds on a desktop workstation, caught by process-spawn watcher (git.exe parent=spt daemon, conhost.exe child each).\n\n### 5.9 `Instant - Duration` underflow-panics on a freshly-booted host  `[REQ-HAZARD-INSTANT-UNDERFLOW]`\n- **Failure:** `Instant::now() - Duration::from_secs(N)` panics `overflow when subtracting duration from instant` when the process's monotonic clock is younger than `N` — i.e. the host booted less than `N` ago. The peer pump primed its cadence legs with `Instant::now() - 86_400s` to mean \"everything due now\"; on a Windows runner with sub-24h uptime the pump thread panicked at startup, so the subnet never converged (CI `pump_and_dispatch_self_drive_the_subnet` failed, run 27082417706). It is *environment-conditional* — green on any host up longer than the offset, red below it — so it slips local dev and only bites a fresh CI box or a just-rebooted machine.\n- **Invariant:** NEVER compute an instant in the past by subtracting from `Instant::now()`. Represent \"never run / due now\" as `Option<Instant> = None` and gate on forward `now.duration_since(past)` only (`peerloop::due`). No backward instant arithmetic anywhere in scheduling.\n…\n\n…\n","startLine":100,"lineNumbers":[100,null,126,127,null,130,131,132,133,134,135,136,137,138,139,140,141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,158,159,160,161,162,163,164,165,166,167,168,169,170,171,172,173,174,175,176,177,178,179,180,181,182,183,184,185,186,187,188,189,190,191,192,193,194,195,196,197,198,199,200,201,202,203,204,205,206,207,208,209,210,211,212,213,214,215,216,217,218,219,220,221,222,223,224,225,226,227,228,229,230,null,234,null,286]},"meta":{"source":{"type":"path","value":"C:\\Users\\decid\\Documents\\projects\\spt-core\\docs\\KNOWN-HAZARDS.md"},"limits":{"columnTruncated":{"maxColumn":768}}}},"isError":false,"timestamp":1784434185026}}

(The trailing-blank omission after `ESC[2J`\n   is semantically correct and NOT the bug.)\n\n## Decisions\n\n<!-- [doc->REQ-BROKER-OUTPUT-BEFORE-EXIT] -->\n1. **One FIFO sequencer per attach sink.** The PTY drain/output writer is the sole\n   sequencer for terminal Output and Exit: Exit is enqueued behind all prior output for\n   each sink (drain EOF/completion first, then Exit). A mutex alone is insufficient —\n   producer order is the contract. Output-before-Exit is a production-path invariant,\n   regression-proven end-to-end (broker → attach → rc).\n   <!-- [doc->REQ-RC-VT-TEARDOWN] -->\n2. **rc display teardown is unconditional, idempotent, and separate from input teardown.**\n   A display RAII guard (distinct from the OS input/raw-mode guard) runs on every exit\n   path including errors and unwind: best-effort SGR reset, full scroll-region reset,\n   cursor show, leave alternate screen, clear+home — emitted while VT output processing is\n   still enabled, THEN the prior console output mode is restored, then parting prose.\n   <!-- [doc->REQ-PICKER-PURGE-STRUCTURED] -->\n3. **A TUI surface has exactly one renderer.** Core verbs invoked from inside an active\n   TUI return structured outcomes and write NOTHING to the terminal; the TUI converts\n   outcomes to model state (picker purge → `model.flash`). Alternatives (suspend/restore\n   + forced baseline reset) are fallbacks, not the design. Baseline-desync regressions\n   require a stateful/recording backend — pure view snapshots cannot catch them.\n   <!-- [doc->REQ-SCREENGRID-REPAINT-MODE-REPLAY] -->\n4. **Cold repaint replays every tracked render-affecting mode** (DECSTBM at minimum)\n   before final cursor placement, under a stateful emulator contract: dirty screen +\n   synthesized repaint + next raw frame ≡ server grid.\n5. **Deferred (P2, seeds — not this milestone):** `Exit { after_seq }` final-watermark\n   defense; herdr-style per-client semantic baseline (only relevant if spt ever transforms\n   live frames instead of forwarding raw bytes).\n\nDesign principles adopted from prior art (ideas only): one baseline per terminal surface;\nblanks are real cells; attach/reconnect/resize/write-failure invalidates the baseline and\nforces full clear+repaint; commit a baseline only after successful delivery; teardown is\nidempotent and comprehensive (panic path included). Explicitly rejected: importing a\nmultiplexer stack; committing a baseline while ignoring write errors.\n\n## Consequences\n\n- A short-lived child's final bytes (including erases and mode resets) always render\n  before the session ends; \"the last frame\" is a guarantee, not a race.\n- No rc exit path leaves the operator's terminal in the child's display state.\n- TUI screens repaint whole and correct after any out-of-band mutation, because there are\n  no sanctioned out-of-band mutations left and the unsanctioned ones invalidate the\n  baseline.\n- Repaint after reattach/resize is state-complete: scrolling behaves identically on both\n  ends of the wire.\n"}],"details":{"displayContent":{"text":"# ADR-0043: Terminal render lifecycle — ordered output, owned baselines, unconditional teardown\n\n- Status: accepted (doyle triage 2026-07-18, RC-RENDER-TRUTH milestone, W3)\n- Source: hertz stale-glyphs/missing-whitespace RCA (2026-07-18, doyle seam-verified all\n  four legs same day: broker exit-waiter vs controller_writer ordering, `RawGuard::drop`\n  display-state gap, picker inline-purge stderr under the live TUI, ScreenGrid repaint\n  DECSTBM omission).

(The trailing-blank omission after `ESC[2J`\n   is semantically correct and NOT the bug.)\n\n## Decisions\n\n<!-- [doc->REQ-BROKER-OUTPUT-BEFORE-EXIT] -->\n1. **One FIFO sequencer per attach sink.** The PTY drain/output writer is the sole\n   sequencer for terminal Output and Exit: Exit is enqueued behind all prior output for\n   each sink (drain EOF/completion first, then Exit). A mutex alone is insufficient —\n   producer order is the contract. Output-before-Exit is a production-path invariant,\n   regression-proven end-to-end (broker → attach → rc).\n   <!-- [doc->REQ-RC-VT-TEARDOWN] -->\n2. **rc display teardown is unconditional, idempotent, and separate from input teardown.**\n   A display RAII guard (distinct from the OS input/raw-mode guard) runs on every exit\n   path including errors and unwind: best-effort SGR reset, full scroll-region reset,\n   cursor show, leave alternate screen, clear+home — emitted while VT output processing is\n   still enabled, THEN the prior console output mode is restored, then parting prose.\n   <!-- [doc->REQ-PICKER-PURGE-STRUCTURED] -->\n3. **A TUI surface has exactly one renderer.** Core verbs invoked from inside an active\n   TUI return structured outcomes and write NOTHING to the terminal; the TUI converts\n   outcomes to model state (picker purge → `model.flash`). Alternatives (suspend/restore\n   + forced baseline reset) are fallbacks, not the design. Baseline-desync regressions\n   require a stateful/recording backend — pure view snapshots cannot catch them.\n   <!-- [doc->REQ-SCREENGRID-REPAINT-MODE-REPLAY] -->\n4. **Cold repaint replays every tracked render-affecting mode** (DECSTBM at minimum)\n   before final cursor placement, under a stateful emulator contract: dirty screen +\n   synthesized repaint + next raw frame ≡ server grid.\n5. **Deferred (P2, seeds — not this milestone):** `Exit { after_seq }` final-watermark\n   defense; herdr-style per-client semantic baseline (only relevant if spt ever transforms\n   live frames instead of forwarding raw bytes).\n\nDesign principles adopted from prior art (ideas only): one baseline per terminal surface;\nblanks are real cells; attach/reconnect/resize/write-failure invalidates the baseline and\nforces full clear+repaint; commit a baseline only after successful delivery; teardown is\nidempotent and comprehensive (panic path included). Explicitly rejected: importing a\nmultiplexer stack; committing a baseline while ignoring write errors.\n\n## Consequences\n\n- A short-lived child's final bytes (including erases and mode resets) always render\n  before the session ends; \"the last frame\" is a guarantee, not a race.\n- No rc exit path leaves the operator's terminal in the child's display state.\n- TUI screens repaint whole and correct after any out-of-band mutation, because there are\n  no sanctioned out-of-band mutations left and the unsanctioned ones invalidate the\n  baseline.\n- Repaint after reattach/resize is state-complete: scrolling behaves identically on both\n  ends of the wire.\n","startLine":1,"lineNumbers":[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87]},"meta":{"source":{"type":"path","value":"C:\\Users\\decid\\Documents\\projects\\spt-core\\docs\\adr\\0043-terminal-render-lifecycle.md"}}},"isError":false,"timestamp":1784434185069}}

Output drain pump — the ConPTY-DSR auto-answer reader (M3a A2).\r\n//!\r\n//!

Prerequisite for the follow-up sticky ID-marker redo (#8/#14 marker-half).\n\n**Status:** DESIGN (doyle, 2026-06-30). Operator-ratified decisions folded in. Companion: ADR-0031.\n\n---\n\n## Problem\n\nA cold `spt rc` / attach subscribes with `from_seq = 0` (rc.rs:1109, dispatch.rs:350). `become_controller` (broker.rs:402-416) builds the initial batch = the **entire retained raw-byte ring** (`ring.iter().filter(seq >= from_seq)`) and streams it into the operator's fresh terminal. For a modern alt-screen TUI (Claude Code) that ring is a **rendering protocol mid-stream** — alt-screen enter/exit, absolute cursor moves, repaints, SGR runs, a torn oldest chunk. Dumped raw into a fresh terminal it produces: corrupt scrollback (#6), stray cells (#7), resize debris (#8). This is exactly the failure ADR-0008 named when it moved *content* extraction off the PTY: \"the PTY byte stream of an alt-screen TUI is a rendering protocol, not a content log... repaints corrupt …\n\nThe raw ring is correct for *history* (byte-exact record) but wrong as an *attach repaint*. We need a server-side **render model** that interprets the byte stream into an authoritative current-screen and synthesizes ONE clean repaint at attach.\n\n---\n\n## Decisions (ratified)\n\n1. **Scope = current screen only.** The grid tracks the visible viewport (cell buffer + cursor + main/alt buffer + relevant modes), NOT scrollback. Scrollback stays the raw ring for history. The grid drives **only** the attach repaint. Scroll-through-session-history-as-a-feature is explicitly out of scope (and not what #6 reports — #6 is replay corruption, not a missing scroll feature).\n2. **Engine = `vte` crate + clean-room grid.** Use `vte` (alacritty's byte→action parser state machine — small, battle-tested on real-world escape sequences) for the byte→`Perform` action layer. Clean-room a thin `ScreenGrid { cells, cursor, alt/main, modes }` implementing `vte::Perform`. Per ADR-0001 the grid is clean-room; the VT *parser* is the one vetted dep — a universal, non-harness-specific, spec-fragile-at-the-edges state machine is exactly where a vetted parser earns its place (edge-sequence bugs are precisely the artifacts #6 exists to kill). Recorded in ADR-0031.\n3. **ADR-0008 reconciliation (companion ADR-0031).** ADR-0008's governing split is \"**render** surfaces read the PTY / **content** surfaces read the logs.\" It retired the PTY-byte parser ONLY for content (the digest). #6 is a **render** grid — the render-reads-PTY side ADR-0008 explicitly preserves. #6 *completes* that side: render-reads-PTY needs interpretation to give a clean repaint. The content parser stays retired (the digest still projects from normalized logs). Not a reversal.\n4. **No wire change.** The attach wire stays `AttachRecord::Output { seq, data_b64 }`. Only the **content of the initial batch** changes — a synthesized clean-screen repaint instead of the raw ring. Live frames after attach still stream raw bytes unchanged (the client's own terminal applies them). Cross-node attach (#4) and any client are agnostic — they render whatever bytes arrive.\n\n---\n\n## Architecture\n\n**Placement — broker-side, alongside the PTY + ring.** The grid lives per session next to `OutputLog` (broker.rs:213). It is fed the same bytes `OutputLog::append` receives, on the session drain path.\n\n**Feed (continuous state, off the hot lock).** As the drain thread hands a chunk to `append`, it also feeds the chunk to the session's `ScreenGrid` (vte advance). The grid update must NOT run under the `Mutex<OutputLog>` lock in a way that adds latency to fan-out (REQ-HAZARD-INJECT-CONTROL-COEXIST 7.12). Two acceptable shapes (todlando's impl choice, whichever keeps append lock-clean):\n  - (a) grid owned by the drain thread (single-writer, no shared lock) — the drain advances the grid, then `append`s to the ring; a snapshot is taken under a short separate lock only when a repaint is requested; or\n  - (b) grid behind its own lock, advanced after the ring append, never held across a fan-out `try_send`.\nThe grid is **single-writer** (the drain thread) by construction — mirrors the existing single-producer ring.\n\n**Repaint synthesis at attach.** `become_controller` (broker.rs:402) and `add_viewer` (broker.rs:459), instead of streaming the raw ring as the initial batch, request `grid.render_repaint()` → a synthesized byte sequence that paints the current screen cleanly into a fresh terminal:\n  - reset/clear (`ESC[!p` soft-reset or `ESC[2J` + home as appropriate), main/alt-buffer selection matching current state, SGR reset, then the current cell buffer row-by-row with minimal SGR runs, then cursor to its live position and mode (DECTCEM etc.).\n  - assigned the **current `next_seq - 1`** (or a repaint pseudo-seq) so the render-cursor dedup (rc.rs:1333) and `delivered_through` (broker.rs:265) stay monotonic and the post-repaint live frames continue in-order.\nAfter the repaint, the controller/viewer receives live frames from the ring floor forward (skip-to-live semantics for viewers unchanged).\n\n**Alt-screen correctness (the #6 core).** If the session is currently in the alt-screen (a full-screen TUI like CC), the repaint paints the alt-screen current state and does NOT dump main-screen scrollback — killing the \"raw history above the TUI\" corruption. If in the main screen, the repaint paints the visible main screen; scrollback is the client's own terminal history, not our raw-ring dump.\n\n**OS-neutrality (CONTEXT L483).** The grid is the OS-neutral replay layer the raw byte stream cannot be: it consumes the `OutputStream` bytes uniformly whether the backend is forkpty (raw-ordered pipe) or ConPTY (repaint-on-resize). It slots behind the `SessionSurface`/`OutputStream` abstraction (spt-term/surface.rs — designed OS-neutral for exactly this). No forkpty/ConPTY semantics leak into the grid.\n\n---\n\n## Build-time refinement (todlando, counter-38 W8 — for doyle's gate)\n\n**Repaint is scoped to a COLD attach (`from_seq == 0`); a resume-from-floor (`from_seq > 0`) keeps the raw-ring re-fetch.** The build surfaced a concrete interaction the design's one-line CONTROLLER-GAP-RESUME note (below) left implicit: the repaint's collapsed pseudo-seq (`broker.next_seq - 1`) is a *forward jump* from a controller's requested `from_seq`, and the controller's brain-side dedup is a **strict reject-gap** (exactly-once resume, B2) that FATALS a forward jump — so a naive \"repaint on every attach\" wedged a cold attach to a pre-populated ring (`loopback_attach_to_a_prepopulated_ring`). Resolution, kept deliberately conservative so it does **not** rewire the exactly-once resume machinery:\n\n- **Cold attach (`from_seq == 0`)** — the `spt rc` / `endpoint run --attach` case #6 targets: the broker emits the clean-screen **repaint**, and the serving brain **baselines** its strict cursor on that first frame (`Brain::baseline_next_output`, set by `attach`/`attach_as` iff `from_seq == 0`), then reverts to strict reject-gap for every subsequent LIVE frame. The repaint is the complete current screen, so nothing prior is owed; live exactly-once (a b4 drop still re-fetches) is preserved.\n- **Resume-from-floor (`from_seq > 0`)** — a controller recovering a b4 drop-don't-block gap: **unchanged**. Raw-ring replay from the floor + strict reject-gap + `ControllerIrrecoverablyBehind` detection are byte-for-byte as before. The \"re-repaint on mid-session resume\" idea in the CONTROLLER-GAP-RESUME note is therefore **NOT** taken this pass (it would obsolete the irrecoverable-behind path); it remains a possible future enhancement.\n\nNet: #6 changes ONLY the cold-attach initial batch (its documented scope); the controller resume/exactly-once hazard machinery is untouched. Viewers use the existing snap-above path, which accepts the repaint's forward jump natively.\n\n## Hazard checklist (must-not-rebreak — from the seam map §4)\n\n- **REQ-HAZARD-INJECT-CONTROL-COEXIST (7.12):** repaint bytes delivered OFF the drain thread via the existing controller/viewer writer threads; the grid advance + `render_repaint` snapshot must NOT block the fan-out under the log lock.\n- **REQ-HAZARD-CONTROLLER-WRITER-REORDER (7.21):** exactly one live `controller_writer`, ascending seq; the repaint pseudo-seq must preserve monotonicity + epoch-gating (`controller_epoch` broker.rs:233).\n- **REQ-HAZARD-VIEWER-ISOLATION (7.7) + REQ-VIEWER-SKIP-TO-LIVE-ON-EVICT:** a viewer repaint is still isolated + evict-not-park; an evicted viewer re-subscribes from the current floor with a fresh repaint, rate-limited (RESUBSCRIBE_INTERVAL).\n- **REQ-HAZARD-CONTROLLER-GAP-RESUME:** a controller re-fetch from `delivered_through` still works — a mid-session resume can re-issue a repaint from current grid state (better than the old ring re-fetch when the ring rolled).\n- **REQ-HAZARD-ATTACH-WEDGE (7.11) / EFFECT-JOURNAL-PTY-WEDGE (7.14):** the grid is on the OUTPUT path only; it touches neither the input/effect journal nor the QUIC op deadlines. No new `block_on`.\n- **Bounded memory:** the grid is a fixed viewport (rows×cols), bounded by definition; resize reallocates. No unbounded growth (unlike deferred scrollback spillover).\n\n---\n\n## Scope boundaries\n\n- **IN:** the server-side current-screen grid + `render_repaint` replacing the raw-ring initial batch at `become_controller`/`add_viewer`. Fixes #6, #7, #8-artifacts.\n- **OUT (follow-up):** the sticky ID-marker redo (#8/#14 marker-half) — the grid makes a proper per-frame sticky top-row overlay possible; re-enabling the marker (currently flagged OFF, W2 #14) as a grid-backed sticky overlay is a separate follow-up REQ, not this design.\n- **OUT (separate):** #12 (Win10 rc VT-output enable) — client-side console mode, dispatched separately (REQ-RC-WIN-VT-OUTPUT). Note: #12's fix is a PREREQ for the repaint to render on Win10 conhost (the repaint is still ANSI bytes; without VT-output-processing they'd print literally). The two compose.\n- **OUT:** scrollback-in-grid / on-disk scrollback spillover (CONTEXT L488-489, deferred).\n\n---\n\n## Build plan\n\n- Activate **REQ-BROKER-SCREEN-GRID** — `doc, impl, unit, int`.\n- **Units:** vte→grid application (print/CSI/SGR/cursor/alt-screen enter-exit → cell/cursor state); `render_repaint` produces a clean paint for (a) a main-screen state, (b) an alt-screen TUI state, (c) after a resize; repaint pseudo-seq monotonicity; grid single-writer / no-lock-across-fanout.\n- **Int:** a broker session driven with a scripted alt-screen byte sequence (enter alt-screen, paint, scroll, partial repaint) → a fresh attach receives a CLEAN current-screen repaint (assert no raw alt-screen-enter / no torn-chunk debris in the initial batch), then live frames continue in-order. Reuse the dummy-harness/mock-adapter fixture pattern.\n- **[twohost]:** NOT needed — this is single-host attach-render (the grid is server-side, the wire is unchanged; #4 already owns the cross-node int). A single-host int suffices.\n- **Docs:** ADR-0031 (companion: vte dep rationale + ADR-0008 render-vs-content reconciliation); a note in CONTEXT.md §terminal (the grid is the OS-neutral render-replay layer) if warranted; no public CLI surface change.\n- **Gate:** fresh-target clippy --workspace --all-targets + nextest (grid units + the alt-screen int) + traceable; the artifact bugs are inherently hard to unit-assert byte-exact — the int asserts *absence* of the known corruption markers in the initial batch.\n\n---\n\n## Open impl questions for todlando (design-level answered; impl-level his call)\n\n1. Grid feed shape (a) drain-owns-grid vs (b) grid-behind-own-lock — pick whichever keeps `append` fan-out lock-clean.\n2. `render_repaint` minimality (full-screen repaint vs diff) — full clean repaint is fine for v1 (attach is infrequent); a diff optimization is deferred.\n3. vte version pin + a clippy/deny check on the new dep (first-party lock discipline at release).\n\n\n[Some lines truncated to 768 chars]"}],"details":{"displayContent":{"text":"# V0.19.0 P6 — Server-side screen grid (clean repaint on attach)\r\n\r\n**Bug:** field-bug-milestone #6 (REQ-BROKER-SCREEN-GRID).

This is exactly the failure ADR-0008 named when it moved *content* extraction off the PTY: \"the PTY byte stream of an alt-screen TUI is a rendering protocol, not a content log... repaints corrupt …\n\r\nThe raw ring is correct for *history* (byte-exact record) but wrong as an *attach repaint*. We need a server-side **render model** that interprets the byte stream into an authoritative current-screen and synthesizes ONE clean repaint at attach.\r\n\r\n---\r\n\r\n## Decisions (ratified)\r\n\r\n1. **Scope = current screen only.** The grid tracks the visible viewport (cell buffer + cursor + main/alt buffer + relevant modes), NOT scrollback. Scrollback stays the raw ring for history. The grid drives **only** the attach repaint. Scroll-through-session-history-as-a-feature is explicitly out of scope (and not what #6 reports — #6 is replay corruption, not a missing scroll feature).\r\n2. **Engine = `vte` crate + clean-room grid.** Use `vte` (alacritty's byte→action parser state machine — small, battle-tested on real-world escape sequences) for the byte→`Perform` action layer. Clean-room a thin `ScreenGrid { cells, cursor, alt/main, modes }` implementing `vte::Perform`. Per ADR-0001 the grid is clean-room; the VT *parser* is the one vetted dep — a universal, non-harness-specific, spec-fragile-at-the-edges state machine is exactly where a vetted parser earns its place (edge-sequence bugs are precisely the artifacts #6 exists to kill). Recorded in ADR-0031.\r\n3. **ADR-0008 reconciliation (companion ADR-0031).** ADR-0008's governing split is \"**render** surfaces read the PTY / **content** surfaces read the logs.\" It retired the PTY-byte parser ONLY for content (the digest). #6 is a **render** grid — the render-reads-PTY side ADR-0008 explicitly preserves. #6 *completes* that side: render-reads-PTY needs interpretation to give a clean repaint. The content parser stays retired (the digest still projects from normalized logs). Not a reversal.\r\n4. **No wire change.** The attach wire stays `AttachRecord::Output { seq, data_b64 }`. Only the **content of the initial batch** changes — a synthesized clean-screen repaint instead of the raw ring. Live frames after attach still stream raw bytes unchanged (the client's own terminal applies them). Cross-node attach (#4) and any client are agnostic — they render whatever bytes arrive.\r\n\r\n---\r\n\r\n## Architecture\r\n\r\n**Placement — broker-side, alongside the PTY + ring.** The grid lives per session next to `OutputLog` (broker.rs:213). It is fed the same bytes `OutputLog::append` receives, on the session drain path.\r\n\r\n**Feed (continuous state, off the hot lock).** As the drain thread hands a chunk to `append`, it also feeds the chunk to the session's `ScreenGrid` (vte advance). The grid update must NOT run under the `Mutex<OutputLog>` lock in a way that adds latency to fan-out (REQ-HAZARD-INJECT-CONTROL-COEXIST 7.12). Two acceptable shapes (todlando's impl choice, whichever keeps append lock-clean):\r\n  - (a) grid owned by the drain thread (single-writer, no shared lock) — the drain advances the grid, then `append`s to the ring; a snapshot is taken under a short separate lock only when a repaint is requested; or\r\n  - (b) grid behind its own lock, advanced after the ring append, never held across a fan-out `try_send`.\r\nThe grid is **single-writer** (the drain thread) by construction — mirrors the existing single-producer ring.\r\n\r\n**Repaint synthesis at attach.** `become_controller` (broker.rs:402) and `add_viewer` (broker.rs:459), instead of streaming the raw ring as the initial batch, request `grid.render_repaint()` → a synthesized byte sequence that paints the current screen cleanly into a fresh terminal:\r\n  - reset/clear (`ESC[!p` soft-reset or `ESC[2J` + home as appropriate), main/alt-buffer selection matching current state, SGR reset, then the current cell buffer row-by-row with minimal SGR runs, then cursor to its live position and mode (DECTCEM etc.).\r\n  - assigned the **current `next_seq - 1`** (or a repaint pseudo-seq) so the render-cursor dedup (rc.rs:1333) and `delivered_through` (broker.rs:265) stay monotonic and the post-repaint live frames continue in-order.\r\nAfter the repaint, the controller/viewer receives live frames from the ring floor forward (skip-to-live semantics for viewers unchanged).\r\n\r\n**Alt-screen correctness (the #6 core).** If the session is currently in the alt-screen (a full-screen TUI like CC), the repaint paints the alt-screen current state and does NOT dump main-screen scrollback — killing the \"raw history above the TUI\" corruption. If in the main screen, the repaint paints the visible main screen; scrollback is the client's own terminal history, not our raw-ring dump.\r\n\r\n**OS-neutrality (CONTEXT L483).** The grid is the OS-neutral replay layer the raw byte stream cannot be: it consumes the `OutputStream` bytes uniformly whether the backend is forkpty (raw-ordered pipe) or ConPTY (repaint-on-resize). It slots behind the `SessionSurface`/`OutputStream` abstraction (spt-term/surface.rs — designed OS-neutral for exactly this). No forkpty/ConPTY semantics leak into the grid.\r\n\r\n---\r\n\r\n## Build-time refinement (todlando, counter-38 W8 — for doyle's gate)\r\n\r\n**Repaint is scoped to a COLD attach (`from_seq == 0`); a resume-from-floor (`from_seq > 0`) keeps the raw-ring re-fetch.** The build surfaced a concrete interaction the design's one-line CONTROLLER-GAP-RESUME note (below) left implicit: the repaint's collapsed pseudo-seq (`broker.next_seq - 1`) is a *forward jump* from a controller's requested `from_seq`, and the controller's brain-side dedup is a **strict reject-gap** (exactly-once resume, B2) that FATALS a forward jump — so a naive \"repaint on every attach\" wedged a cold attach to a pre-populated ring (`loopback_attach_to_a_prepopulated_ring`). Resolution, kept deliberately conservative so it does **not** rewire the exactly-once resume machinery:\r\n\r\n- **Cold attach (`from_seq == 0`)** — the `spt rc` / `endpoint run --attach` case #6 targets: the broker emits the clean-screen **repaint**, and the serving brain **baselines** its strict cursor on that first frame (`Brain::baseline_next_output`, set by `attach`/`attach_as` iff `from_seq == 0`), then reverts to strict reject-gap for every subsequent LIVE frame. The repaint is the complete current screen, so nothing prior is owed; live exactly-once (a b4 drop still re-fetches) is preserved.\r\n- **Resume-from-floor (`from_seq > 0`)** — a controller recovering a b4 drop-don't-block gap: **unchanged**. Raw-ring replay from the floor + strict reject-gap + `ControllerIrrecoverablyBehind` detection are byte-for-byte as before. The \"re-repaint on mid-session resume\" idea in the CONTROLLER-GAP-RESUME note is therefore **NOT** taken this pass (it would obsolete the irrecoverable-behind path); it remains a possible future enhancement.\r\n\r\nNet: #6 changes ONLY the cold-attach initial batch (its documented scope); the controller resume/exactly-once hazard machinery is untouched. Viewers use the existing snap-above path, which accepts the repaint's forward jump natively.\r\n\r\n## Hazard checklist (must-not-rebreak — from the seam map §4)\r\n\r\n- **REQ-HAZARD-INJECT-CONTROL-COEXIST (7.12):** repaint bytes delivered OFF the drain thread via the existing controller/viewer writer threads; the grid advance + `render_repaint` snapshot must NOT block the fan-out under the log lock.\r\n- **REQ-HAZARD-CONTROLLER-WRITER-REORDER (7.21):** exactly one live `controller_writer`, ascending seq; the repaint pseudo-seq must preserve monotonicity + epoch-gating (`controller_epoch` broker.rs:233).\r\n- **REQ-HAZARD-VIEWER-ISOLATION (7.7) + REQ-VIEWER-SKIP-TO-LIVE-ON-EVICT:** a viewer repaint is still isolated + evict-not-park; an evicted viewer re-subscribes from the current floor with a fresh repaint, rate-limited (RESUBSCRIBE_INTERVAL).\r\n- **REQ-HAZARD-CONTROLLER-GAP-RESUME:** a controller re-fetch from `delivered_through` still works — a mid-session resume can re-issue a repaint from current grid state (better than the old ring re-fetch when the ring rolled).\r\n- **REQ-HAZARD-ATTACH-WEDGE (7.11) / EFFECT-JOURNAL-PTY-WEDGE (7.14):** the grid is on the OUTPUT path only; it touches neither the input/effect journal nor the QUIC op deadlines. No new `block_on`.\r\n- **Bounded memory:** the grid is a fixed viewport (rows×cols), bounded by definition; resize reallocates. No unbounded growth (unlike deferred scrollback spillover).\r\n\r\n---\r\n\r\n## Scope boundaries\r\n\r\n- **IN:** the server-side current-screen grid + `render_repaint` replacing the raw-ring initial batch at `become_controller`/`add_viewer`. Fixes #6, #7, #8-artifacts.\r\n- **OUT (follow-up):** the sticky ID-marker redo (#8/#14 marker-half) — the grid makes a proper per-frame sticky top-row overlay possible; re-enabling the marker (currently flagged OFF, W2 #14) as a grid-backed sticky overlay is a separate follow-up REQ, not this design.\r\n- **OUT (separate):** #12 (Win10 rc VT-output enable) — client-side console mode, dispatched separately (REQ-RC-WIN-VT-OUTPUT). Note: #12's fix is a PREREQ for the repaint to render on Win10 conhost (the repaint is still ANSI bytes; without VT-output-processing they'd print literally). The two compose.\r\n- **OUT:** scrollback-in-grid / on-disk scrollback spillover (CONTEXT L488-489, deferred).\r\n\r\n---\r\n\r\n## Build plan\r\n\r\n- Activate **REQ-BROKER-SCREEN-GRID** — `doc, impl, unit, int`.\r\n- **Units:** vte→grid application (print/CSI/SGR/cursor/alt-screen enter-exit → cell/cursor state); `render_repaint` produces a clean paint for (a) a main-screen state, (b) an alt-screen TUI state, (c) after a resize; repaint pseudo-seq monotonicity; grid single-writer / no-lock-across-fanout.\r\n- **Int:** a broker session driven with a scripted alt-screen byte sequence (enter alt-screen, paint, scroll, partial repaint) → a fresh attach receives a CLEAN current-screen repaint (assert no raw alt-screen-enter / no torn-chunk debris in the initial batch), then live frames continue in-order. Reuse the dummy-harness/mock-adapter fixture pattern.\r\n- **[twohost]:** NOT needed — this is single-host attach-render (the grid is server-side, the wire is unchanged; #4 already owns the cross-node int). A single-host int suffices.\r\n- **Docs:** ADR-0031 (companion: vte dep rationale + ADR-0008 render-vs-content reconciliation); a note in CONTEXT.md §terminal (the grid is the OS-neutral render-replay layer) if warranted; no public CLI surface change.\r\n- **Gate:** fresh-target clippy --workspace --all-targets + nextest (grid units + the alt-screen int) + traceable; the artifact bugs are inherently hard to unit-assert byte-exact — the int asserts *absence* of the known corruption markers in the initial batch.\r\n\r\n---\r\n\r\n## Open impl questions for todlando (design-level answered; impl-level his call)\r\n\r\n1. Grid feed shape (a) drain-owns-grid vs (b) grid-behind-own-lock — pick whichever keeps `append` fan-out lock-clean.\r\n2. `render_repaint` minimality (full-screen repaint vs diff) — full clean repaint is fine for v1 (attach is infrequent); a diff optimization is deferred.\r\n3. vte version pin + a clippy/deny check on the new dep (first-party lock discipline at release).\r\n","startLine":1,"lineNumbers":[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91]},"meta":{"source":{"type":"path","value":"C:\\Users\\decid\\Documents\\projects\\spt-core\\V0.19.0-P6-SCREEN-GRID-DESIGN.md"},"limits":{"columnTruncated":{"maxColumn":768}}}},"isError":false,"timestamp":1784434198746}}

(alt-screen enter/exit, absolute cursor moves, repaints, a torn oldest chunk);\r\n//! replayed raw into a fresh terminal it corrupts scrollback (#6) and leaves stray\r\n//! cells (#7) / resize debris (#8). The [`ScreenGrid`] interprets the same byte\r\n//! stream into an authoritative **current screen** and synthesizes ONE clean\r\n//! [`ScreenGrid::render_repaint`] the client can paint into a fresh terminal.\r\n//!\r\n//! **Scope (ratified, ADR-0031):** current screen only — the visible viewport\r\n//! (cell buffer + cursor + main/alt buffer + the modes a repaint needs). Scrollback\r\n//! stays the raw ring (history). The grid drives ONLY the attach repaint; live\r\n//! frames after attach are the unchanged raw bytes.\r\n//!\r\n//! **Provenance (ADR-0001 / ADR-0031):** the byte→action layer is the vetted `vte`\r\n//! parser state machine (the one non-clean-room dep — a universal, spec-fragile VT\r\n//! machine where a hand-roll would reproduce the exact artifacts #6 kills).

The broker kernel (B1 + B2) — the stable half of the broker/brain split.\n//!\n//! Per ADR-0004 §B the broker holds **only** the resources a live consumer\n//! would lose continuity on if the logic restarted: the PTY master+writer and\n//! the spawned child (both via [`spt_term::PtySession`]), and the accepted\n//! client / listening sockets. It runs **no logic** — no routing, registry,\n//! manifest parse, or lifecycle. It is a relay: spawn a child under a PTY,\n//! forward its output to the brain, inject the brain's input, report exit.\n//!\n//! ## Gapless handoff (B2 — the load-bearing invariant)\n//!\n//! A brain may be killed and restarted at any moment (a routine self-update, a\n//! crash). The broker — and every hosted child — must survive that untouched,\n//! and the new brain must re-attach to the output stream **gaplessly and\n//! exactly-once** (Spike #1 made real). Two mechanisms:\n//!\n//! - **Sequenced, buffered output.** Each session's output is appended to an\n//!   [`OutputLog`]: every chunk gets a monotonic per-session `seq` and is held\n//!   in a bounded ring. The current subscriber (a brain connection) receives\n//!   chunks live; all subscriber writes happen *under the log lock*, so frames\n//!   reach the brain in strict `seq` order with no interleave.\n//! - **Resume from a cursor.** A reconnecting brain sends `subscribe` with its\n//!   last-seen `seq + 1`; the broker replays the ring from there, then streams\n//!   live. The brain dedups by `seq`. Output produced *while no brain was\n//!   attached* sits in the ring and is replayed on the next subscribe — so a\n//!   brain restart loses nothing.\n//!\n//! Sessions are therefore **broker-owned and outlive any one connection**: a\n//! brain disconnect only detaches the subscriber; the child, its PTY, and the\n//! output log persist. A session leaves the table only when its child exits\n//! (reaped by the exit waiter) or is explicitly killed.\n// [impl->REQ-DAEMON-2]\n\nuse std::collections::{HashMap, HashSet, VecDeque};\nuse std::io;\nuse std::sync::atomic::{AtomicBool, AtomicU32, AtomicU64, AtomicUsize, Ordering};\nuse std::sync::mpsc::{channel, sync_channel, Receiver, RecvTimeoutError, Sender, SyncSender, TrySendError};\nuse std::sync::{Arc, Mutex, OnceLock};\nuse std::thread::{self, JoinHandle};\nuse std::time::{Duration, Instant};\n\nuse interprocess::local_socket::{prelude::*, Stream};\nuse spt_term::{Drain, PtySession, ScreenGrid, SessionSurface, SurfaceSize};\n\nuse spt_net::net::attach::AttachIntent;\nuse spt_net::net::endpoint::EndpointAddr;\nuse spt_store::perch::{resolve_perch_path, ParentHint};\n\nuse crate::codec::read_frame;\nuse crate::conn::{BrokerConn, ConnWrite};\nuse crate::effect::{EffectJournal, EffectKey, EffectKind, Minter, Outcome};\nuse crate::frame::{Envelope, Role};\nuse crate::msg::{\n    applied_envelope, decode_bytes, displaced_envelope, endpoint_injected_envelope,\n    evicted_envelope, net_dialed_envelope, output_envelope,\n    size_envelope, subscribed_envelope, AdapterApplyReq, BrainRestarted, EndpointInputReq,\n    ErrorEvent, ExitEvent, InputReq, KillReq, NetDialReq, NetPresenceSubscribeReq, NetSent,\n    BrokerImageReply, StallEvictsReply, NetStatusReply, NetStreamOpenReq, NetStreamOpened, NetStreamSendReq, NetStreamSubscribeReq,\n    NetStreamsReply, NetStreamOpenerReply, NetStreamOpenerReq, NetStreamRetireReq, NetStreamRetired, NetStreamUnsubscribeReq, NetStreamUnsubscribed, MetMember, PairCodeSubmit, PairJoinReply, PairJoinReq, PairMeetReq, ResizeReq, SessionInfo, SessionsReply, SpawnReq,\n    SpawnConflict, Spawned, SubscribeOutcome, SubscribeReq, UnsubscribeReq, KIND_BRAIN_RESTART, KIND_BRAIN_RESTARTED, KIND_ENDPOINT_INPUT, KIND_ERROR, KIND_EXIT,\n    KIND_INPUT, KIND_KILL, KIND_NET_DIAL, KIND_NET_DIAL_LOOPBACK, KIND_NET_DIAL_SUBMIT,\n    KIND_NET_DIAL_SUBMITTED, KIND_NET_PRESENCE_SUBSCRIBE,\n    KIND_NET_SENT,\n    KIND_ADAPTER_APPLY, KIND_APPLIED,\n    KIND_BROKER_IMAGE, KIND_BROKER_IMAGE_REPLY, KIND_STALL_EVICTS, KIND_STALL_EVICTS_REPLY,\n    KIND_NET_STATUS, KIND_NET_STATUS_REPLY, KIND_NET_STREAMS, KIND_NET_STREAMS_REPLY,\n    KIND_NET_STREAM_OPEN, KIND_NET_STREAM_OPENED, KIND_NET_STREAM_OPENER, KIND_NET_STREAM_OPENER_REPLY, KIND_NET_STREAM_RETIRE, KIND_NET_STREAM_RETIRED, KIND_NET_STREAM_SEND, KIND_NET_STREAM_SUBSCRIBE,\n    KIND_NET_STREAM_UNSUBSCRIBE, KIND_NET_STREAM_UNSUBSCRIBED,\n    KIND_MET_MEMBER, KIND_PAIR_CODE_SUBMIT, KIND_PAIR_JOIN, KIND_PAIR_JOINED, KIND_PAIR_MEET, KIND_RESIZE, KIND_SESSIONS, KIND_SESSIONS_REPLY, KIND_SPAWN,\n    KIND_SPAWNED, KIND_SPAWN_CONFLICT, KIND_SPAWN_FRESH, KIND_SUBSCRIBE, KIND_UNSUBSCRIBE,\n};\nuse crate::nethost::{NetHost, NET_EFFECT_SESSION};\nuse crate::translation::{key_to_bytes, InjectFloor, KeyCmd, ToBinary, TranslationChild};\nuse crate::transport::{recv_hello, DaemonTransport, LocalSocketTransport};\n\n/// The shared, serialized send side of one brain connection.

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//! (reaped by the exit waiter) or is explicitly killed.\r\n// [impl->REQ-DAEMON-2]\r\n\r\nuse std::collections::{HashMap, HashSet, VecDeque};\r\nuse std::io;\r\nuse std::sync::atomic::{AtomicBool, AtomicU32, AtomicU64, AtomicUsize, Ordering};\r\nuse std::sync::mpsc::{channel, sync_channel, Receiver, RecvTimeoutError, Sender, SyncSender, TrySendError};\r\nuse std::sync::{Arc, Mutex, OnceLock};\r\nuse std::thread::{self, JoinHandle};\r\nuse std::time::{Duration, Instant};\r\n\r\nuse interprocess::local_socket::{prelude::*, Stream};\r\nuse spt_term::{Drain, PtySession, ScreenGrid, SessionSurface, SurfaceSize};\r\n\r\nuse spt_net::net::attach::AttachIntent;\r\nuse spt_net::net::endpoint::EndpointAddr;\r\nuse spt_store::perch::{resolve_perch_path, ParentHint};\r\n\r\nuse crate::codec::read_frame;\r\nuse crate::conn::{BrokerConn, ConnWrite};\r\nuse crate::effect::{EffectJournal, EffectKey, EffectKind, Minter, Outcome};\r\nuse crate::frame::{Envelope, Role};\r\nuse crate::msg::{\r\n    applied_envelope, decode_bytes, displaced_envelope, endpoint_injected_envelope,\r\n    evicted_envelope, net_dialed_envelope, output_envelope,\r\n    size_envelope, subscribed_envelope, AdapterApplyReq, BrainRestarted, EndpointInputReq,\r\n    ErrorEvent, ExitEvent, InputReq, KillReq, NetDialReq, NetPresenceSubscribeReq, NetSent,\r\n    BrokerImageReply, StallEvictsReply, NetStatusReply, NetStreamOpenReq, NetStreamOpened, NetStreamSendReq, NetStreamSubscribeReq,\r\n    NetStreamsReply, NetStreamOpenerReply, NetStreamOpenerReq, NetStreamRetireReq, NetStreamRetired, NetStreamUnsubscribeReq, NetStreamUnsubscribed, MetMember, PairCodeSubmit, PairJoinReply, PairJoinReq, PairMeetReq, ResizeReq, SessionInfo, SessionsReply, SpawnReq,\r\n    SpawnConflict, Spawned, SubscribeOutcome, SubscribeReq, UnsubscribeReq, KIND_BRAIN_RESTART, KIND_BRAIN_RESTARTED, KIND_ENDPOINT_INPUT, KIND_ERROR, KIND_EXIT,\r\n    KIND_INPUT, KIND_KILL, KIND_NET_DIAL, KIND_NET_DIAL_LOOPBACK, KIND_NET_DIAL_SUBMIT,\r\n    KIND_NET_DIAL_SUBMITTED, KIND_NET_PRESENCE_SUBSCRIBE,\r\n    KIND_NET_SENT,\r\n    KIND_ADAPTER_APPLY, KIND_APPLIED,\r\n    KIND_BROKER_IMAGE, KIND_BROKER_IMAGE_REPLY, KIND_STALL_EVICTS, KIND_STALL_EVICTS_REPLY,\r\n    KIND_NET_STATUS, KIND_NET_STATUS_REPLY, KIND_NET_STREAMS, KIND_NET_STREAMS_REPLY,\r\n    KIND_NET_STREAM_OPEN, KIND_NET_STREAM_OPENED, KIND_NET_STREAM_OPENER, KIND_NET_STREAM_OPENER_REPLY, KIND_NET_STREAM_RETIRE, KIND_NET_STREAM_RETIRED, KIND_NET_STREAM_SEND, KIND_NET_STREAM_SUBSCRIBE,\r\n    KIND_NET_STREAM_UNSUBSCRIBE, KIND_NET_STREAM_UNSUBSCRIBED,\r\n    KIND_MET_MEMBER, KIND_PAIR_CODE_SUBMIT, KIND_PAIR_JOIN, KIND_PAIR_JOINED, KIND_PAIR_MEET, KIND_RESIZE, KIND_SESSIONS, KIND_SESSIONS_REPLY, KIND_SPAWN,\r\n    KIND_SPAWNED, KIND_SPAWN_CONFLICT, KIND_SPAWN_FRESH, KIND_SUBSCRIBE, KIND_UNSUBSCRIBE,\r\n};\r\nuse crate::nethost::{NetHost, NET_EFFECT_SESSION};\r\nuse crate::translation::{key_to_bytes, InjectFloor, KeyCmd, ToBinary, TranslationChild};\r\nuse crate::transport::{recv_hello, DaemonTransport, LocalSocketTransport};\r\n\r\n/// The shared, serialized send side of one brain connection.

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//! (reaped by the exit waiter) or is explicitly killed.\r\n// [impl->REQ-DAEMON-2]\r\n\r\nuse std::collections::{HashMap, HashSet, VecDeque};\r\nuse std::io;\r\nuse std::sync::atomic::{AtomicBool, AtomicU32, AtomicU64, AtomicUsize, Ordering};\r\nuse std::sync::mpsc::{channel, sync_channel, Receiver, RecvTimeoutError, Sender, SyncSender, TrySendError};\r\nuse std::sync::{Arc, Mutex, OnceLock};\r\nuse std::thread::{self, JoinHandle};\r\nuse std::time::{Duration, Instant};\r\n\r\nuse interprocess::local_socket::{prelude::*, Stream};\r\nuse spt_term::{Drain, PtySession, ScreenGrid, SessionSurface, SurfaceSize};\r\n\r\nuse spt_net::net::attach::AttachIntent;\r\nuse spt_net::net::endpoint::EndpointAddr;\r\nuse spt_store::perch::{resolve_perch_path, ParentHint};\r\n\r\nuse crate::codec::read_frame;\r\nuse crate::conn::{BrokerConn, ConnWrite};\r\nuse crate::effect::{EffectJournal, EffectKey, EffectKind, Minter, Outcome};\r\nuse crate::frame::{Envelope, Role};\r\nuse crate::msg::{\r\n    applied_envelope, decode_bytes, displaced_envelope, endpoint_injected_envelope,\r\n    evicted_envelope, net_dialed_envelope, output_envelope,\r\n    size_envelope, subscribed_envelope, AdapterApplyReq, BrainRestarted, EndpointInputReq,\r\n    ErrorEvent, ExitEvent, InputReq, KillReq, NetDialReq, NetPresenceSubscribeReq, NetSent,\r\n    BrokerImageReply, StallEvictsReply, NetStatusReply, NetStreamOpenReq, NetStreamOpened, NetStreamSendReq, NetStreamSubscribeReq,\r\n    NetStreamsReply, NetStreamOpenerReply, NetStreamOpenerReq, NetStreamRetireReq, NetStreamRetired, NetStreamUnsubscribeReq, NetStreamUnsubscribed, MetMember, PairCodeSubmit, PairJoinReply, PairJoinReq, PairMeetReq, ResizeReq, SessionInfo, SessionsReply, SpawnReq,\r\n    SpawnConflict, Spawned, SubscribeOutcome, SubscribeReq, UnsubscribeReq, KIND_BRAIN_RESTART, KIND_BRAIN_RESTARTED, KIND_ENDPOINT_INPUT, KIND_ERROR, KIND_EXIT,\r\n    KIND_INPUT, KIND_KILL, KIND_NET_DIAL, KIND_NET_DIAL_LOOPBACK, KIND_NET_DIAL_SUBMIT,\r\n    KIND_NET_DIAL_SUBMITTED, KIND_NET_PRESENCE_SUBSCRIBE,\r\n    KIND_NET_SENT,\r\n    KIND_ADAPTER_APPLY, KIND_APPLIED,\r\n    KIND_BROKER_IMAGE, KIND_BROKER_IMAGE_REPLY, KIND_STALL_EVICTS, KIND_STALL_EVICTS_REPLY,\r\n    KIND_NET_STATUS, KIND_NET_STATUS_REPLY, KIND_NET_STREAMS, KIND_NET_STREAMS_REPLY,\r\n    KIND_NET_STREAM_OPEN, KIND_NET_STREAM_OPENED, KIND_NET_STREAM_OPENER, KIND_NET_STREAM_OPENER_REPLY, KIND_NET_STREAM_RETIRE, KIND_NET_STREAM_RETIRED, KIND_NET_STREAM_SEND, KIND_NET_STREAM_SUBSCRIBE,\r\n    KIND_NET_STREAM_UNSUBSCRIBE, KIND_NET_STREAM_UNSUBSCRIBED,\r\n    KIND_MET_MEMBER, KIND_PAIR_CODE_SUBMIT, KIND_PAIR_JOIN, KIND_PAIR_JOINED, KIND_PAIR_MEET, KIND_RESIZE, KIND_SESSIONS, KIND_SESSIONS_REPLY, KIND_SPAWN,\r\n    KIND_SPAWNED, KIND_SPAWN_CONFLICT, KIND_SPAWN_FRESH, KIND_SUBSCRIBE, KIND_UNSUBSCRIBE,\r\n};\r\nuse crate::nethost::{NetHost, NET_EFFECT_SESSION};\r\nuse crate::translation::{key_to_bytes, InjectFloor, KeyCmd, ToBinary, TranslationChild};\r\nuse crate::transport::{recv_hello, DaemonTransport, LocalSocketTransport};\r\n\r\n/// The shared, serialized send side of one brain connection.

Status: **PASS (core thesis, Windows ConPTY)** with named open gaps.\n> Throwaway code: `../spt-spikes/spike-01-broker-handoff` (outside the spt-core repo, not shipped).\n> Drives ROADMAP Stage B Spike #1 + codex red-team FATAL #2/#3 (`docs/reviews/STAGE-A-codex-redteam.md`).\n\n## Question\n\nADR-0004 claims a PTY child + an open client connection survive a daemon-logic (\"brain\") restart because a stable \"broker\" holds the load-bearing handles.

Exact mechanism deferred to design; the commitment is that migration is a first-class supported path, not a manual rebuild.\n 6|\n*7|Harness-independent core for the SPT ecosystem. Provides inter-agent messaging, live-agent lifecycle, terminal wrapping, self-update, and networking primitives — as both a Rust library workspace and a canonical reference binary. Designed so any agent runtime (Claude Code, Codex, Cursor, headless, future harnesses) can interface with the SPT ecosystem either by shelling out to the binary or by linking the crates directly.\n 8|\n*9|Successor to `claude_skill_owl` (today's \"modern SPT\"), which is being rebuilt as `spt-core` to untether the system from Claude Code and lift it to a general-purpose agent-ecosystem core.\n 10|\n 11|## Language\n 12|\n...\n 16|**spt.exe / spt** (canonical binary):\n*17|The reference binary built from the workspace. Replaces today's `owl.exe`. Most external integrations (plugins, hooks, scripts in other harnesses) interact with spt-core *only* through this binary — fire-and-forget subcommands, long-running listeners under a parent harness's process supervisor, etc. Unix builds use the same name without `.exe`.\n 18|\n 19|**library workspace**:\n*20|The set of Rust crates that compose spt-core. Consumers that want a deeper integration than shelling out to `spt.exe` link these crates directly. The reference binary is itself a consumer of the workspace. The expected non-binary consumers are future first-party services that link Rust directly.\n 21|\n 22|**spt plugin** (separate downstream project — NOT an spt-core deliverable):\n*23|A rebuilt version of today's Claude Code `spt` plugin. It is the **first consumer** built *atop* spt-core and the **acceptance proof** of spt-core v1 (it reaches feature parity with modern SPT while delegating all core functionality to spt-core, primarily via `spt.exe`, with deeper hooks where useful) — but it **lives and builds in its own repository, outside spt-core**. It is a Claude-Code-specific *adapter*: it holds the Claude Code conventions (hooks, slash-commands, skill/plugin layout, `claude` se...\n 24|\n 25|**Pi** (disambiguation — two meanings, never conflate):\n*26|(1) **Pi, the coding agent/harness** (`badlogic/pi-mono`) — a harness example alongside Claude Code and Codex; this is the meaning in user-facing harness lists. (2) **Pi-class node** — Raspberry-Pi-class low-power hardware hosting a Shell-only or headless SPT node; an incidental hardware descriptor, never an explicit product example. Public-facing docs must disambiguate or avoid the bare word.\n*27|_Avoid_: bare \"Pi node\" when the harness is meant.\n 28|\n 29|**spt-daemon** (per-machine supervisor):\n*30|The single always-on, one-per-machine logical supervisor. Owns the PTYs for all hosted sessions, the node's network identity + WAN endpoint, the subnet registry, all spools, **all poll-listener logic, and all Psyche/pulse loops** — everything is consolidated here (no separate poll-listener or Psyche-wrapper processes; listeners already touch sessions directly under capsule/idle, and Psyche wrappers already invoke harness binaries directly, so they belong in the one supervisor). Collapses what the siste...\n 31|\n*32|Internally the logical daemon is split into two implementation layers for seamless self-update (see Self-update):\n*33|- **broker** (stable \"kernel\") — holds *only* the un-transferable, must-not-die resources: PTY master fds, the spawned harness child processes, and listening network sockets. Minimal, dumb, versioned local IPC. Almost never updates.\n*34|- **daemon brain** (\"userspace\") — all logic (routing, registry, pulse/psyche loops, manifest parsing, update orchestration). Restarts freely on update; rehydrates from disk state and re-attaches to the broker's held handles.\n 35|\n*36|Logical addressing is unchanged — still one per-machine `spt-daemon`; the broker is an internal layer, not separately addressable. There is exactly **one broker per machine** (per `SPT_HOME`) — *not* one per endpoint: a single broker holds every hosted endpoint's resources, and it is present whenever the daemon runs, even with zero endpoints online (the bare-daemon case). It is therefore the always-present per-machine layer, which is why the single-daemon lock + liveness anchor belong to it.\n 37|\n*38|**in-session relay**:\n*39|A thin, stateless `spt.exe` task that exists only in **harness-hosted** sessions (where the agent harness is the parent process and spt cannot reach into its process tree — today's Monitor model). It streams the daemon brain's events into the session's stdout. All *stateful* listener logic lives in the daemon; the relay is a dumb pipe, freely killable and respawnable. **spt-hosted** sessions need no separate harness-owned relay — the daemon owns the PTY and consumes the same poll feed itself. Idle de...\n 40|\n 41|### Deliverable shape\n 42|\n...\n 44|\n*45|- **Library crates** — the deeper integration path. Used by future first-party services that link Rust directly.\n*46|- **`spt.exe` / `spt`** — the canonical binary, built from the workspace. The primary integration path for harness plugins and external tooling, which mostly fire it as a subprocess at various surfaces (one-shot commands, poll listeners under a Monitor-tool-equivalent, hook tap-ins).\n 47|\n*48|Both surfaces are first-class. Wire-protocol parity between them is a versioning concern from day one (a non-Rust client speaking to `spt.exe` and a Rust client linking the crates must see the same observable behavior).\n 49|\n 50|## Runtime model\n 51|\n*52|spt-core is harness-independent: it does not know about Claude Code, Codex, Cursor, or any other agent runtime.

Replaces today's `owl.exe`. Most external integrations (plugins, hooks, scripts in other harnesses) interact with spt-core *only* through this binary — fire-and-forget subcommands, long-running listeners under a parent harness's process supervisor, etc. Unix builds use the same name without `.exe`.\n 18│\n 19│**library workspace**:\n*20│The set of Rust crates that compose spt-core. Consumers that want a deeper integration than shelling out to `spt.exe` link these crates directly. The reference binary is itself a consumer of the workspace.

(2) **Pi-class node** — Raspberry-Pi-class low-power hardware hosting a Shell-only or headless SPT node; an incidental hardware descriptor, never an explicit product example. Public-facing docs must disambiguate or avoid the bare word.\n*27│_Avoid_: bare \"Pi node\" when the harness is meant.\n 28│\n 29│**spt-daemon** (per-machine supervisor):\n*30│The single always-on, one-per-machine logical supervisor. Owns the PTYs for all hosted sessions, the node's network identity + WAN endpoint, the subnet registry, all spools, **all poll-listener logic, and all Psyche/pulse loops** — everything is consolidated here (no separate poll-listener or Psyche-wrapper processes; listeners already touch sessions directly under capsule/idle, and Psyche wrappers already invoke harness binaries directly, so they belong in the one supervisor). Collapses what the siste...\n 31│\n*32│Internally the logical daemon is split into two implementation layers for seamless self-update (see Self-update):\n*33│- **broker** (stable \"kernel\") — holds *only* the un-transferable, must-not-die resources: PTY master fds, the spawned harness child processes, and listening network sockets. Minimal, dumb, versioned local IPC. Almost never updates.\n*34│- **daemon brain** (\"userspace\") — all logic (routing, registry, pulse/psyche loops, manifest parsing, update orchestration). Restarts freely on update; rehydrates from disk state and re-attaches to the broker's held handles.\n 35│\n*36│Logical addressing is unchanged — still one per-machine `spt-daemon`; the broker is an internal layer, not separately addressable. There is exactly **one broker per machine** (per `SPT_HOME`) — *not* one per endpoint: a single broker holds every hosted endpoint's resources, and it is present whenever the daemon runs, even with zero endpoints online (the bare-daemon case). It is therefore the always-present per-machine layer, which is why the single-daemon lock + liveness anchor belong to it.\n 37│\n*38│**in-session relay**:\n*39│A thin, stateless `spt.exe` task that exists only in **harness-hosted** sessions (where the agent harness is the parent process and spt cannot reach into its process tree — today's Monitor model). It streams the daemon brain's events into the session's stdout. All *stateful* listener logic lives in the daemon; the relay is a dumb pipe, freely killable and respawnable. **spt-hosted** sessions need no separate harness-owned relay — the daemon owns the PTY and consumes the same poll feed itself.

The primary integration path for harness plugins and external tooling, which mostly fire it as a subprocess at various surfaces (one-shot commands, poll listeners under a Monitor-tool-equivalent, hook tap-ins).\n 47│\n*48│Both surfaces are first-class. Wire-protocol parity between them is a versioning concern from day one (a non-Rust client speaking to `spt.exe` and a Rust client linking the crates must see the same observable behavior).\n 49│\n 50│## Runtime model\n 51│\n*52│spt-core is harness-independent: it does not know about Claude Code, Codex, Cursor, or any other agent runtime.

CONTEXT:177 says spt-hosted Psyche is\n*38│   daemon-spawned \"same as above\"; today there is no such path.\n*39│2. **Psyche liveness is relay-process-bound**, not daemon-authoritative —\n 40│   contradicts CONTEXT:194 (alive iff the daemon's endpoint table says so).\n 41│   A relay swap/kill disturbs the Psyche.\n 42│3. The `int` evidence is **type-level, not production-level**: `daemon_e2e`\n*43│   constructs `BrainLifecycle` directly; nothing proves the *brain process*\n 44│   hosts it for a real endpoint.

Neither touches the registered service manager. A user with\n*14│   a service installed expects `spt daemon start|stop` to drive *that*.\n 15│2. **`spt daemon run` is platform-inconsistent.**\n 16│   - Linux: runs the daemon **inline/foreground** (blocks the terminal).\n*17│   - Windows: ends up an **invisible background task** (a detached respawn).\n 18│   Same verb, different behavior.\n*19│3. **Auto-start competes with the service.** Any `spt` command that needs the\n*20│   daemon calls `ensure_running()` → `spawn_detached()`, which starts a *manual*\n*21│   daemon even when a managed service exists → two daemons fight for the socket\n*22│   (exactly the kitsubito loop).\n 23│\n 24│## Current code (baseline)\n 25│\n*26│- `crates/spt/src/cli.rs`: `cmd_daemon_run()` → `spt_daemon::Daemon::run()`\n*27│  (foreground loop); `cmd_daemon_stop()` → `is_running()` + `request_stop()`\n*28│  (IPC graceful); `DaemonCmd::Run` carries `visible_alias = \"start\"`.\n*29│- `crates/spt-daemon/src/daemon.rs`: `ensure_running()` → `spawn_detached()`\n*30│  (Linux fork-style; Windows `DETACHED_PROCESS | CREATE_NO_WINDOW`, de-elevated\n*31│  via `deelevate`). `request_stop()` = IPC stop.\n\n# DAEMON-LIFECYCLE-VERIFICATION.md\n *1│# Daemon-lifecycle int verification — kitsubito systemd rig (2026-06-08)\n  2│\n  3│> Manual live-rig verification of REQ-DAEMON-6/7/8 (commit `ccbef73`) against a\n *4│> real systemd **user** unit.

Ensure rust toolchain +\n*30|   clippy match CI (rustup default = repo toolchain).\n 31|4. **Workflow edits** (`.github/workflows/*`):\n*32|   - matrix `runs-on`: `ubuntu-latest` → `[self-hosted, Linux]`;\n*33|     `windows-latest` → `[self-hosted, Windows]`.\n 34|   - traceability job → `[self-hosted, Linux]`.\n 35|   - DROP `actions/cache` steps (persistent local target/cargo make them\n*36|     pointless and they upload gigabytes for nothing).\n*37|   - ADD `timeout-minutes: 20` on test jobs — today's handoff.rs hang burned 22\n*38|     min before a manual cancel; on our own boxes a wedged job blocks the\n 39|     single runner slot, so the timeout matters MORE self-hosted.\n*40|   - `concurrency: { group: ci-${{ github.ref }}, cancel-in-progress: true }`\n 41|     so a re-push cancels the stale run instead of queuing behind it.\n 42|5. **Keep the workflow surface identical** — push → `gh run watch` → green\n 43|   stays the loop; PR checks/traceability gate unchanged.\n*44|6. **Decommission**: nothing to delete; hosted runners simply stop being\n\n# CLAUDE.md\n*1|# spt-core — agent working rules\n 2|\n*3|Harness-independent core for an agent ecosystem (messaging, live-agent lifecycle, terminal hosting, P2P networking, runtime-manifest harness contract). Rust crates + a single `spt` binary. Clean-room rebuild of `claude_skill_owl`.\n 4|\n*5|**Orientation — read before working:** `PRD.md` (requirements), `ROADMAP.md` (build path), `CONTEXT.md` (glossary/model, authoritative for meaning), `docs/adr/` (decisions), `docs/KNOWN-HAZARDS.md` (invariants we must not re-break), `docs/{STORAGE,MANIFEST,CONTEXT-MEMORY,DOCS-STRATEGY,TRACEABILITY}.md`.\n 6|\n 7|## Requirement traceability (binding)\n 8|\n*9|This project uses `traceable-reqs` (`traceable-reqs.toml` = the authoritative `REQ-*` registry). The full contract is `docs/TRACEABILITY.md`. The rules you must follow:\n 10|\n*11|1. **Tag evidence in the same change.** When you write a function/test/doc-section that satisfies a requirement stage, add its tag in that same commit:\n 12|   `// [impl->REQ-FOO]` · `// [unit->REQ-FOO]` · `<!-- [doc->REQ-FOO] -->`\n*13|   Stages: `doc` / `impl` / `unit` / `int`. Tag *on or immediately above* the real evidence — never at file tops to satisfy coverage.\n 14|2. **Run `traceable-reqs check` before declaring work done.** Exit-1 means missing/invalid evidence — fix it, don't ship it.\n*15|3. **New requirement → add it to `traceable-reqs.toml` first** (with a `REQ-*` id), then satisfy it. No untracked work; no untagged evidence.\n*16|4. **KNOWN-HAZARDS are `REQ-HAZARD-*` requirements** — each needs a test before it's \"covered.\" Treat the hazard list as a conformance checklist you must satisfy, not advice.\n*17|5. **Activate, don't pre-fail.** Requirements you aren't yet working stay `required_stages = []`. Activate (set real stages) only when starting the milestone that delivers them.\n 18|\n 19|## Other conventions\n 20|\n 21|- Match surrounding code style; copy-verbatim the sister project's stable wire/schema formats (ADR-0001), clean-room everything else.\n*22|- Honor every `docs/KNOWN-HAZARDS.md` invariant — these are real bugs already paid for once.\n 23|- Docs are dual-audience (human + AI dev-agent) per `docs/DOCS-STRATEGY.md`; doc generation is CI-gated against drift.\n*24|- Commit messages end with the project's co-author trailer: `Co-authored by: <your live agent name>` (e.g. `Co-authored by: todlando`).\n*25|- **Worktrees (binding, operator-ruled 2026-07-05):** every `git worktree` (gate rigs, agent scratch, anything) goes under `.worktrees/` in THIS project's root (`.gitignore`d) — e.g. `git worktree add --detach .worktrees/gate-<sha> <sha>`. NEVER create worktrees as siblings of the project dir; stray sibling folders accumulate orphan-pinned skeletons and pollute `~/Documents/projects`. Remove yours when done (`git worktree remove` + prune; retry later if a handle pins it).\n 26|\n*27|If you finish a significant body of work without need for user intervention, or if your context gets too high, you can clear your own context and keep moving:\n 28|1. Create a JIT plan for the next immediate body of work, if it isn't already planned\n 29|2.

Execute the /self-clear skill\n\n# CONTEXT.md\n 2|\n*3|**Platform scope:** Windows + Linux for v1. macOS is out (no test machine available) but kept structurally easy — `portable-pty` and Iroh both support it, so macOS is a later test/CI-budget decision, not a re-architecture.\n 4|\n*5|**Legacy migration:** it should be possible — ideally *automatic* — for a user to migrate an existing `claude_skill_owl` (modern SPT) install to spt-core (identity, agents, tracked Psyche context). Exact mechanism deferred to design; the commitment is that migration is a first-class supported path, not a manual rebuild.\n 6|\n*7|Harness-independent core for the SPT ecosystem. Provides inter-agent messaging, live-agent lifecycle, terminal wrapping, self-update, and networking primitives — as both a Rust library workspace and a canonical reference binary. Designed so any agent runtime (Claude Code, Codex, Cursor, headless, future harnesses) can interface with the SPT ecosystem either by shelling out to the binary or by linking the crates directly.\n 8|\n*9|Successor to `claude_skill_owl` (today's \"modern SPT\"), which is being rebuilt as `spt-core` to untether the system from Claude Code and lift it to a general-purpose agent-ecosystem core.\n 10|\n 11|## Language\n 12|\n...\n 16|**spt.exe / spt** (canonical binary):\n*17|The reference binary built from the workspace. Replaces today's `owl.exe`. Most external integrations (plugins, hooks, scripts in other harnesses) interact with spt-core *only* through this binary — fire-and-forget subcommands, long-running listeners under a parent harness's process supervisor, etc. Unix builds use the same name without `.exe`.\n 18|\n 19|**library workspace**:\n*20|The set of Rust crates that compose spt-core. Consumers that want a deeper integration than shelling out to `spt.exe` link these crates directly. The reference binary is itself a consumer of the workspace. The expected non-binary consumers are future first-party services that link Rust directly.\n 21|\n 22|**spt plugin** (separate downstream project — NOT an spt-core deliverable):\n*23|A rebuilt version of today's Claude Code `spt` plugin. It is the **first consumer** built *atop* spt-core and the **acceptance proof** of spt-core v1 (it reaches feature parity with modern SPT while delegating all core functionality to spt-core, primarily via `spt.exe`, with deeper hooks where useful) — but it **lives and builds in its own repository, outside spt-core**. It is a Claude-Code-specific *adapter*: it holds the Claude Code conventions (hooks, slash-commands, skill/plugin layout, `claude` se...\n 24|\n 25|**Pi** (disambiguation — two meanings, never conflate):\n*26|(1) **Pi, the coding agent/harness** (`badlogic/pi-mono`) — a harness example alongside Claude Code and Codex; this is the meaning in user-facing harness lists. (2) **Pi-class node** — Raspberry-Pi-class low-power hardware hosting a Shell-only or headless SPT node; an incidental hardware descriptor, never an explicit product example. Public-facing docs must disambiguate or avoid the bare word.\n*27|_Avoid_: bare \"Pi node\" when the harness is meant.\n 28|\n 29|**spt-daemon** (per-machine supervisor):\n*30|The single always-on, one-per-machine logical supervisor. Owns the PTYs for all hosted sessions, the node's network identity + WAN endpoint, the subnet registry, all spools, **all poll-listener logic, and all Psyche/pulse loops** — everything is consolidated here (no separate poll-listener or Psyche-wrapper processes; listeners already touch sessions directly under capsule/idle, and Psyche wrappers already invoke harness binaries directly, so they belong in the one supervisor). Collapses what the siste...\n 31|\n*32|Internally the logical daemon is split into two implementation layers for seamless self-update (see Self-update):\n*33|- **broker** (stable \"kernel\") — holds *only* the un-transferable, must-not-die resources: PTY master fds, the spawned harness child processes, and listening network sockets. Minimal, dumb, versioned local IPC. Almost never updates.\n*34|- **daemon brain** (\"userspace\") — all logic (routing, registry, pulse/psyche loops, manifest parsing, update orchestration). Restarts freely on update; rehydrates from disk state and re-attaches to the broker's held handles.\n 35|\n*36|Logical addressing is unchanged — still one per-machine `spt-daemon`; the broker is an internal layer, not separately addressable. There is exactly **one broker per machine** (per `SPT_HOME`) — *not* one per endpoint: a single broker holds every hosted endpoint's resources, and it is present whenever the daemon runs, even with zero endpoints online (the bare-daemon case). It is therefore the always-present per-machine layer, which is why the single-daemon lock + liveness anchor belong to it.\n 37|\n*38|**in-session relay**:\n*39|A thin, stateless `spt.exe` task that exists only in **harness-hosted** sessions (where the agent harness is the parent process and spt cannot reach into its process tree — today's Monitor model). It streams the daemon brain's events into the session's stdout. All *stateful* listener logic lives in the daemon; the relay is a dumb pipe, freely killable and respawnable. **spt-hosted** sessions need no separate harness-owned relay — the daemon owns the PTY and consumes the same poll feed itself. Idle de...\n 40|\n 41|### Deliverable shape\n 42|\n...\n 44|\n*45|- **Library crates** — the deeper integration path. Used by future first-party services that link Rust directly.\n*46|- **`spt.exe` / `spt`** — the canonical binary, built from the workspace. The primary integration path for harness plugins and external tooling, which mostly fire it as a subprocess at various surfaces (one-shot commands, poll listeners under a Monitor-tool-equivalent, hook tap-ins).\n 47|\n*48|Both surfaces are first-class. Wire-protocol parity between them is a versioning concern from day one (a non-Rust client speaking to `spt.exe` and a Rust client linking the crates must see the same observable behavior).\n 49|\n 50|## Runtime model\n 51|\n*52|spt-core is harness-independent: it does not know about Claude Code, Codex, Cursor, or any other agent runtime. All harness-specific surfaces (how to invoke an agent session, fetch conversation history for an echo commune, detect activity/idleness, etc.) are abstracted behind a runtime layer that consumers supply.\n 53|\n 54|**AgentRuntime** (Rust trait, implementation detail):\n\n# DAEMON-LIFECYCLE-COMPLETION-PLAN.md\n 2|\n*3|> **STATUS: PLANNED (2026-06-15).** JIT plan to *complete* the REQ-DAEMON-1\n 4|> consolidation: move the live-agent lifecycle (Psyche spawn, pulse, echo,\n*5|> drop-ingest, graceful signoff) out of the interim `api listen` process and\n*6|> into the always-on daemon brain, where the RECORDED DESIGN puts it\n 7|> (CONTEXT.md §spt-daemon: \"all poll-listener logic, **and** all Psyche/pulse\n*8|> loops\" / §Psyche: \"a **loop inside the daemon** ... liveness daemon-held, not\n*9|> PID-based\" — :30, :34, :38, :168, :177, :194).

Address-gated like messaging, **plus a consent gate** (driving a session ≠ watching it). **Controller/viewer model:** one interactive **controller** at a time — its viewport sets the PTY size (resize fires on attach + controller window changes; ConPTY repaint cost is why resize stays controller-exclusive); any number of **`--view`** attachers (read-only, never resize, letterbox client-side). `spt rc kick <target>` displaces the incumbent controller (loud notice to them); `--take` = kick + attach in one motion.

Redispatch eligibility is **lifecycle-gated**: finished/terminal stream rows are retired from the dispatcher's enumeration (a fresh dispatcher never re-serves a terminal Attach — the KNOWN-HAZARDS 7.41 frozen-PTY steal/clear class); classification identity is an immutable per-stream opener fact pinned OUTSIDE the evictable data ring (never ring seq 0, which a 4096-chunk roll evicts); claims are retryable on transient worker-setup failure, terminal on terminal outcomes. Distinct from…\n_Avoid_: conflating redispatch with msg dispatch or session-cursor resume; filtering replay by origin identity (the legitimate same-`by` successor re-take must keep working — lifecycle is the discriminator).\n\n<!-- [doc->REQ-RC-KEY-VT-TRANSLATE] -->\n**rc keyboard input (Windows VT translation, v0.13.0 bug 2).** On **Windows** an interactive `spt rc` console reads crossterm **key events** and translates each to **standard xterm VT** (`translate_key_event`) — arrows / Home / End / PgUp/Dn / Insert / Delete / F-keys + modifiers all reach the harness as the universal terminal contract (**agnostic**, NOT win32-input-mode; the legacy console delivers those keys as events, not bytes, so the old byte-pump left them DEAD). **Unix passes through** (its raw-mode stream is already VT; cfg-split, zero Unix change).

A manifest declaring `[session.psyche_init]`\nbrings up a **LiveAgent** (the daemon reconcile hosts its Psyche); a manifest *without*\nit brings up a **ReadyAgent** (a poll listener, no Psyche — see *ReadyAgent* and the\nharness-hosted ready bind at the *seed + bind-time resolution* note above). No\n`--adapter`/picker branch distinguishes them: the daemon live-host reconcile hosts only a\nperch whose **state is `live_agent`** (a `ready_agent`-state perch is skipped at the\nreconcile start-side state gate), and within the live path keys on `psyche_init` presence\n— so `endpoint run` of a ready manifest naturally yields a ready endpoint with no Psyche;\n`--resume <session>` carries its session into the bind for either type. Consequently a\nReadyAgent is now first-class in the **Resume-from-history** offer above: the\nharness-hosted ready bind ledgers a **Boot session row** on bind — exactly as the live\n`establish_perch` path does — so an *offline* ready perch carries the session rows the\noffline+LOCAL Resume-from-history enumerates (previously only LiveAgents did; a ready bind\nwrote `info.json` but never the ledger, so the picker never offered it).\n\n**`spt-<id>` shortcut** (picker `s` keybind, M12-W2):\n<!-- [doc->REQ-RUN-SHORTCUT] -->\nFrom any pre-start options set, `s` writes (or updates) a **`<basename>-<id>` launcher** at the\nproject root that bakes the current selection's **non-interactive** flags (terminal actions\nonly: adapter[:profile] + id + create|resume + start|attach|view; the interactive-only branches\n— Kick/Instantiate/Change-adapter/Fork — are not bakeable). The **basename is a parameter**:\nharness-agnostic spt-core defaults to **`spt`** (→ `spt-<id>`, e.g. `spt-doyle`); an\nadapter/flow **overrides** it (spt-claude-code → `cc`, giving `cc-<id>`) — the Claude-Code-ness\nlives in the adapter, **spt-core never emits `cc`**. The basename must be a *distinct* token,\nnever bare `spt`: a `spt.cmd` wrapper would shadow the real `spt.exe` only under cmd.exe\n(cwd-first search), silently no-op in PowerShell/Unix, and self-recurse — so `spt-<id>` is the\nsafe, consistent form. The launcher is the **current OS's native form**: a **`.cmd`** on\nWindows (the default `PATHEXT` excludes `.ps1`, so a bare name never resolves one; `.cmd` is\nPATHEXT-resolvable), a POSIX **`sh`** (`chmod +x`) on Unix. **Invocation reality** (documented\nin the generated header; `<name>` = `<basename>-<id>`): cmd.exe bare `<name>` in the project dir\n· PowerShell `.\\<name>` · Unix `./<name>`; a *truly-bare* basename on `PATH` is a PATH-installed\nlauncher (`/spt:setup`'s job), not this project-root shortcut. **Overwrite is sentinel-guarded:**\nthe generator writes + checks a generated-by header marker — it overwrites its own prior output\nfreely, but refuses (with a warning) a same-named file that lacks the sentinel, never clobbering\na user file.\n_Avoid_: baking `cc` (a harness name) into spt-core; a bare `spt`/`cc` shadow wrapper; `.ps1`\nshortcuts (PATHEXT won't find them); clobbering a non-generated file.\n\n## Terminal wrapper\n\nThe multiplatform terminal wrapper is the backbone for hosting agent sessions. Supersedes the sister project's planned \"capsule\" (which leaned on psmux). Architecturally a **process supervisor** with an abstract session surface. **The session-surface *mechanism* is delivered in M3a (`crates/spt-term`); the supervisor *process* (term-daemon) is delivered in M3b (`crates/spt-daemon`, 2026-06-03).**\n\n**term-daemon** (process supervisor):\nA long-lived, one-per-machine daemon that owns the PTYs for all hosted sessions, multiplexes them (sessions addressable by name, tmux-style), and accepts attach/detach from frontends. A hosted agent session (a LiveAgent's Self, a ReadyAgent, etc.) runs *inside* a supervised PTY. **Headed** = a frontend is attached and rendering/driving the PTY; **headless** = the session runs with no frontend attached. The daemon's persistence is what lets a session keep running while unwatched and be re-attached \"on a whim.\" *(M3b ✅ — `spt-daemon` hosts many M3a `spt-term` surfaces behind a versioned local IPC, split into a stable **broker** (holds the PTYs/children/sockets) + a restartable **brain** (all logic) so a brain swap leaves hosted sessions gapless; `spt-term` its…\n\n**A view is independent from the endpoint** (invariant):\n<!-- [doc->REQ-HAZARD-VIEWER-CLOSE-DETACH] -->\nAn spt-hosted endpoint runs in a **daemon-owned PTY, decoupled from whatever terminal launched it**. Closing the\ntab/window where `spt endpoint run` was invoked detaches only the `spt rc` attach pump — the endpoint keeps running under\nthe daemon and stays re-attachable via `spt rc <id>`. A view is a transient frontend over a daemon-owned session, never\nthe session's lifeline. *Implementation:* the daemon must never live inside the launching terminal's process grouping —\non Windows the cold-started daemon is launched **job-neutral**: a job-neutral creator (**WMI `Win32_Process.Create`**,\nowned by WmiPrvSE — primary; a `schtasks` one-shot — fallback) starts it OUTSIDE any terminal Job Object from birth, so a\nterminal's `KILL_ON_JOB_CLOSE` job can never reap it (this is why Task-Scheduler-autostarted daemons never had the bug).\nA WMI/scheduler child does not inherit the launching shell's transient environment, so `SPT_*` (notably `SPT_HOME`) is\nforwarded explicitly. `CREATE_BREAKAWAY_FROM_JOB` is retained only as a fallback rung (a job *can* deny it). On Unix the\ndaemon's own session detachment (new session, no controlling terminal) already keeps the SIGHUP of a closing terminal off\nthe daemon's children. (The ConPTY/pseudoconsole isolation is correct on its own — the lifetime binding that leaks is the\nJob Object, not the console.)\n\n**session surface** (library abstraction):\nThe trait spt-core exposes over \"anything you can write input to and read output from\" — delivered in M3a as `spt_term::SessionSurface` (`write_input` + `resize`, with `send_keys`/`send_line` as first-class injection). Native PTY (`spt_term::PtySession`: ConPTY on Windows 10+, `forkpty(3)` on Unix, via the `portable-pty` crate) is the day-one implementation. The abstraction generalizes so future implementations — network-attached surfaces (for `spt-node` remote control), GUI text panes, etc. — are uniform to consumers. Pre-Windows-10 (winpty) is explicitly dropped. **OS-neutral by contract (Spike #4/#5):** the trait bakes in neither `forkpty`'s raw-ordered-pipe nor ConPTY's repaint-on-resize screen-buffer semantics; output is a plain byte stream (`spt_term::…\n\n**input injection**:\nTwo granularities, both first-class. `send-keys` — raw byte stream including escape sequences (e.g. `Ctrl-C`). `send-line` — cooked line-level input flushed on newline (the common case; matches how user input reaches an agent prompt). **PTY input is single-writer (v0.13.0 P0, KNOWN-HAZARDS 7.17):** broker-side, every write to a hosted session's PTY goes through ONE per-session input-writer thread — the sole caller of the blocking `write_input`, fed by a bounded FIFO. All callers (operator keystrokes, message injection, the inject-floor flush) ENQUEUE and return immediately, so a paste burst that fills the harness input buffer parks only that thread, never the broker dispatch thread. A genuinely wedged harness (queue full) DROPS excess input + stamps the perc…\n\n**scrollback**:\nIn-memory ring buffer per session for v1. **On-disk spillover for long sessions is an intended, tracked feature** (deferred past v1, not forgotten) — see `docs/DEFERRED.md`.\n\n**live activity buffer (session digest)**:\nA rolling, human-glanceable view of an endpoint's **recent context** — *what the agent did* (recent user turns + the agent output between them, with **tool-usage sprints collapsed**, e.g. `<endpoint_id> used: **Write** `dir/file.txt` · **Bash** `first ~25 cmd chars` · […]`) **and** *what spt fed the agent* (**context-injection** entries — session-start psyche download, echo-commune mirror, incoming owl messages — collapsed by default, expandable). One time-ordered, glanceable timeline. **How much** is shown (window depth, arg-truncation, sprint-collapse) is the adapter's declared preference, consumer-overridable — *not* a fixed spt-core count. Distinct from both the **raw scrollback ring** (unparsed bytes) and full **transcript history** (the conversation be…\n\n- **Source = normalized session logs, never PTY parsing** (revised 2026-06-12, Gateway grill — supersedes the ADR-0008 source mechanism). A TUI's PTY stream is a *rendering protocol*, not a content log: scroll/resize trigger full repaints (duplicate content), and semantic turn boundaries drown in repaint soup. The split: **render surfaces read the PTY** (the R-TERM raw byte ring, unchanged); **content surfaces read the logs**. The digest reads the **same session logs as the echo-commune** but through its **own adapter-declared extractor** (the `[digest]` seam — see below), not echo's opaque normalizer: one source, two extractors (echo wants rich/opaque records; the digest wants the contract). Presentation knobs (window depth, sprint-collapse, arg truncation)…\n- **Topology-independent.** Because the source is logs, the digest works for harness-hosted endpoints too — Claude Code's per-session JSONL is Path A's worked example. Freshness = file-watch + adapter hook nudges; harnesses with no usable logs push entries directly via **`api digest-entry`** (the Path-B-style door). Near-realtime tailing needs an *incremental* normalize story (design-phase concern: Path A's normalize-command was shaped for occasional pulls).\n- **Thread-spanning across session boundaries.** A live agent's identity persists across many harness *sessions* (a `/clear` or `/compact` rotates the harness `session_id` — see `api boundary` / **post-spawn seam** — while the endpoint identity and `parent_pid` anchor hold).

A manifest declaring `[session.psyche_init]`\r\nbrings up a **LiveAgent** (the daemon reconcile hosts its Psyche); a manifest *without*\r\nit brings up a **ReadyAgent** (a poll listener, no Psyche — see *ReadyAgent* and the\r\nharness-hosted ready bind at the *seed + bind-time resolution* note above). No\r\n`--adapter`/picker branch distinguishes them: the daemon live-host reconcile hosts only a\r\nperch whose **state is `live_agent`** (a `ready_agent`-state perch is skipped at the\r\nreconcile start-side state gate), and within the live path keys on `psyche_init` presence\r\n— so `endpoint run` of a ready manifest naturally yields a ready endpoint with no Psyche;\r\n`--resume <session>` carries its session into the bind for either type.

Supersedes the sister project's planned \"capsule\" (which leaned on psmux). Architecturally a **process supervisor** with an abstract session surface. **The session-surface *mechanism* is delivered in M3a (`crates/spt-term`); the supervisor *process* (term-daemon) is delivered in M3b (`crates/spt-daemon`, 2026-06-03).**\r\n\r\n**term-daemon** (process supervisor):\r\nA long-lived, one-per-machine daemon that owns the PTYs for all hosted sessions, multiplexes them (sessions addressable by name, tmux-style), and accepts attach/detach from frontends. A hosted agent session (a LiveAgent's Self, a ReadyAgent, etc.) runs *inside* a supervised PTY. **Headed** = a frontend is attached and rendering/driving the PTY; **headless** = the session runs with no frontend attached. The daemon's persistence is what lets a session keep running while unwatched and be re-attached \"on a whim.\" *(M3b ✅ — `spt-daemon` hosts many M3a `spt-term` surfaces behind a versioned local IPC, split into a stable **broker** (holds the PTYs/children/sockets) + a restartable **brain** (all logic) so a brain swap leaves hosted sessions gapless; `spt-term` its…\n\r\n**A view is independent from the endpoint** (invariant):\r\n<!-- [doc->REQ-HAZARD-VIEWER-CLOSE-DETACH] -->\r\nAn spt-hosted endpoint runs in a **daemon-owned PTY, decoupled from whatever terminal launched it**. Closing the\r\ntab/window where `spt endpoint run` was invoked detaches only the `spt rc` attach pump — the endpoint keeps running under\r\nthe daemon and stays re-attachable via `spt rc <id>`. A view is a transient frontend over a daemon-owned session, never\r\nthe session's lifeline. *Implementation:* the daemon must never live inside the launching terminal's process grouping —\r\non Windows the cold-started daemon is launched **job-neutral**: a job-neutral creator (**WMI `Win32_Process.Create`**,\r\nowned by WmiPrvSE — primary; a `schtasks` one-shot — fallback) starts it OUTSIDE any terminal Job Object from birth, so a\r\nterminal's `KILL_ON_JOB_CLOSE` job can never reap it (this is why Task-Scheduler-autostarted daemons never had the bug).\r\nA WMI/scheduler child does not inherit the launching shell's transient environment, so `SPT_*` (notably `SPT_HOME`) is\r\nforwarded explicitly. `CREATE_BREAKAWAY_FROM_JOB` is retained only as a fallback rung (a job *can* deny it). On Unix the\r\ndaemon's own session detachment (new session, no controlling terminal) already keeps the SIGHUP of a closing terminal off\r\nthe daemon's children. (The ConPTY/pseudoconsole isolation is correct on its own — the lifetime binding that leaks is the\r\nJob Object, not the console.)\r\n\r\n**session surface** (library abstraction):\r\nThe trait spt-core exposes over \"anything you can write input to and read output from\" — delivered in M3a as `spt_term::SessionSurface` (`write_input` + `resize`, with `send_keys`/`send_line` as first-class injection). Native PTY (`spt_term::PtySession`: ConPTY on Windows 10+, `forkpty(3)` on Unix, via the `portable-pty` crate) is the day-one implementation. The abstraction generalizes so future implementations — network-attached surfaces (for `spt-node` remote control), GUI text panes, etc. — are uniform to consumers. Pre-Windows-10 (winpty) is explicitly dropped. **OS-neutral by contract (Spike #4/#5):** the trait bakes in neither `forkpty`'s raw-ordered-pipe nor ConPTY's repaint-on-resize screen-buffer semantics; output is a plain byte stream (`spt_term::…\n\r\n**input injection**:\r\nTwo granularities, both first-class. `send-keys` — raw byte stream including escape sequences (e.g. `Ctrl-C`). `send-line` — cooked line-level input flushed on newline (the common case; matches how user input reaches an agent prompt). **PTY input is single-writer (v0.13.0 P0, KNOWN-HAZARDS 7.17):** broker-side, every write to a hosted session's PTY goes through ONE per-session input-writer thread — the sole caller of the blocking `write_input`, fed by a bounded FIFO.

One time-ordered, glanceable timeline. **How much** is shown (window depth, arg-truncation, sprint-collapse) is the adapter's declared preference, consumer-overridable — *not* a fixed spt-core count.

A TUI's PTY stream is a *rendering protocol*, not a content log: scroll/resize trigger full repaints (duplicate content), and semantic turn boundaries drown in repaint soup. The split: **render surfaces read the PTY** (the R-TERM raw byte ring, unchanged); **content surfaces read the logs**. The digest reads the **same session logs as the echo-commune** but through its **own adapter-declared extractor** (the `[digest]` seam — see below), not echo's opaque normalizer: one source, two extractors (echo wants rich/opaque records; the digest wants the contract). Presentation knobs (window depth, sprint-collapse, arg truncation)…\n- **Topology-independent.** Because the source is logs, the digest works for harness-hosted endpoints too — Claude Code's per-session JSONL is Path A's worked example. Freshness = file-watch + adapter hook nudges; harnesses with no usable logs push entries directly via **`api digest-entry`** (the Path-B-style door). Near-realtime tailing needs an *incremental* normalize story (design-phase concern: Path A's normalize-command was shaped for occasional pulls).\r\n- **Thread-spanning across session boundaries.** A live agent's identity persists across many harness *sessions* (a `/clear` or `/compact` rotates the harness `session_id` — see `api boundary` / **post-spawn seam** — while the endpoint identity and `parent_pid` anchor hold). The digest follows the **agent thread**, not a single session: its rolling window may bridge a boundary (the tail of session N and the head of session N+1 coexist until the old turns age out), so a glance right after a `/clear` still shows the agent mid-thread rather than empty.

A single\r\naction enum is the source of truth so a future tap-mode (phone PTY) layers on without\r\nre-coupling to keybinds.\r\n_Avoid_: a second bringup path; hard-coupling interaction to physical keybinds.\r\n\r\n**`spt endpoint run` is the spt-hosted bringup for BOTH endpoint types** (v0.12.0):\r\n<!-- [doc->REQ-READY-AGENT-RESUME] -->\r\nThe bringup core is **type-agnostic** — the endpoint TYPE is the adapter manifest's\r\nconcern, not a separate bringup mode. A manifest declaring `[session.psyche_init]`\r\nbrings up a **LiveAgent** (the daemon reconcile hosts its Psyche); a manifest *without*\r\nit brings up a **ReadyAgent** (a poll listener, no Psyche — see *ReadyAgent* and the\r\nharness-hosted ready bind at the *seed + bind-time resolution* note above). No\r\n`--adapter`/picker branch distinguishes them: the daemon live-host reconcile hosts only a\r\nperch whose **state is `live_agent`** (a `ready_agent`-state perch is skipped at the\r\nreconcile start-side state gate), and within the live path keys on `psyche_init` presence\r\n— so `endpoint run` of a ready manifest naturally yields a ready endpoint with no Psyche;\r\n`--resume <session>` carries its session into the bind for either type. Consequently a\r\nReadyAgent is now first-class in the **Resume-from-history** offer above: the\r\nharness-hosted ready bind ledgers a **Boot session row** on bind — exactly as the live\r\n`establish_perch` path does — so an *offline* ready perch carries the session rows the\r\noffline+LOCAL Resume-from-history enumerates (previously only LiveAgents did; a ready bind\r\nwrote `info.json` but never the ledger, so the picker never offered it).\r\n\r\n**`spt-<id>` shortcut** (picker `s` keybind, M12-W2):\r\n<!-- [doc->REQ-RUN-SHORTCUT] -->\r\nFrom any pre-start options set, `s` writes (or updates) a **`<basename>-<id>` launcher** at the\r\nproject root that bakes the current selection's **non-interactive** flags (terminal actions\r\nonly: adapter[:profile] + id + create|resume + start|attach|view; the interactive-only branches\r\n— Kick/Instantiate/Change-adapter/Fork — are not bakeable). The **basename is a parameter**:\r\nharness-agnostic spt-core defaults to **`spt`** (→ `spt-<id>`, e.g. `spt-doyle`); an\r\nadapter/flow **overrides** it (spt-claude-code → `cc`, giving `cc-<id>`) — the Claude-Code-ness\r\nlives in the adapter, **spt-core never emits `cc`**. The basename must be a *distinct* token,\r\nnever bare `spt`: a `spt.cmd` wrapper would shadow the real `spt.exe` only under cmd.exe\r\n(cwd-first search), silently no-op in PowerShell/Unix, and self-recurse — so `spt-<id>` is the\r\nsafe, consistent form. The launcher is the **current OS's native form**: a **`.cmd`** on\r\nWindows (the default `PATHEXT` excludes `.ps1`, so a bare name never resolves one; `.cmd` is\r\nPATHEXT-resolvable), a POSIX **`sh`** (`chmod +x`) on Unix. **Invocation reality** (documented\r\nin the generated header; `<name>` = `<basename>-<id>`): cmd.exe bare `<name>` in the project dir\r\n· PowerShell `.\\<name>` · Unix `./<name>`; a *truly-bare* basename on `PATH` is a PATH-installed\r\nlauncher (`/spt:setup`'s job), not this project-root shortcut. **Overwrite is sentinel-guarded:**\r\nthe generator writes + checks a generated-by header marker — it overwrites its own prior output\r\nfreely, but refuses (with a warning) a same-named file that lacks the sentinel, never clobbering\r\na user file.\r\n_Avoid_: baking `cc` (a harness name) into spt-core; a bare `spt`/`cc` shadow wrapper; `.ps1`\r\nshortcuts (PATHEXT won't find them); clobbering a non-generated file.\r\n\r\n## Terminal wrapper\r\n\r\nThe multiplatform terminal wrapper is the backbone for hosting agent sessions. Supersedes the sister project's planned \"capsule\" (which leaned on psmux). Architecturally a **process supervisor** with an abstract session surface. **The session-surface *mechanism* is delivered in M3a (`crates/spt-term`); the supervisor *process* (term-daemon) is delivered in M3b (`crates/spt-daemon`, 2026-06-03).**\r\n\r\n**term-daemon** (process supervisor):\r\nA long-lived, one-per-machine daemon that owns the PTYs for all hosted sessions, multiplexes them (sessions addressable by name, tmux-style), and accepts attach/detach from frontends. A hosted agent session (a LiveAgent's Self, a ReadyAgent, etc.) runs *inside* a supervised PTY. **Headed** = a frontend is attached and rendering/driving the PTY; **headless** = the session runs with no frontend attached. The daemon's persistence is what lets a session keep running while unwatched and be re-attached \"on a whim.\" *(M3b ✅ — `spt-daemon` hosts many M3a `spt-term` surfaces behind a versioned local IPC, split into a stable **broker** (holds the PTYs/children/sockets) + a restartable **brain** (all logic) so a brain swap leaves hosted sessions gapless; `spt-term` its…\n\r\n**A view is independent from the endpoint** (invariant):\r\n<!-- [doc->REQ-HAZARD-VIEWER-CLOSE-DETACH] -->\r\nAn spt-hosted endpoint runs in a **daemon-owned PTY, decoupled from whatever terminal launched it**. Closing the\r\ntab/window where `spt endpoint run` was invoked detaches only the `spt rc` attach pump — the endpoint keeps running under\r\nthe daemon and stays re-attachable via `spt rc <id>`. A view is a transient frontend over a daemon-owned session, never\r\nthe session's lifeline. *Implementation:* the daemon must never live inside the launching terminal's process grouping —\r\non Windows the cold-started daemon is launched **job-neutral**: a job-neutral creator (**WMI `Win32_Process.Create`**,\r\nowned by WmiPrvSE — primary; a `schtasks` one-shot — fallback) starts it OUTSIDE any terminal Job Object from birth, so a\r\nterminal's `KILL_ON_JOB_CLOSE` job can never reap it (this is why Task-Scheduler-autostarted daemons never had the bug).\r\nA WMI/scheduler child does not inherit the launching shell's transient environment, so `SPT_*` (notably `SPT_HOME`) is\r\nforwarded explicitly. `CREATE_BREAKAWAY_FROM_JOB` is retained only as a fallback rung (a job *can* deny it). On Unix the\r\ndaemon's own session detachment (new session, no controlling terminal) already keeps the SIGHUP of a closing terminal off\r\nthe daemon's children. (The ConPTY/pseudoconsole isolation is correct on its own — the lifetime binding that leaks is the\r\nJob Object, not the console.)\r\n\r\n**session surface** (library abstraction):\r\nThe trait spt-core exposes over \"anything you can write input to and read output from\" — delivered in M3a as `spt_term::SessionSurface` (`write_input` + `resize`, with `send_keys`/`send_line` as first-class injection). Native PTY (`spt_term::PtySession`: ConPTY on Windows 10+, `forkpty(3)` on Unix, via the `portable-pty` crate) is the day-one implementation. The abstraction generalizes so future implementations — network-attached surfaces (for `spt-node` remote control), GUI text panes, etc. — are uniform to consumers. Pre-Windows-10 (winpty) is explicitly dropped. **OS-neutral by contract (Spike #4/#5):** the trait bakes in neither `forkpty`'s raw-ordered-pipe nor ConPTY's repaint-on-resize screen-buffer semantics; output is a plain byte stream (`spt_term::…\n\r\n**input injection**:\r\nTwo granularities, both first-class. `send-keys` — raw byte stream including escape sequences (e.g. `Ctrl-C`). `send-line` — cooked line-level input flushed on newline (the common case; matches how user input reaches an agent prompt). **PTY input is single-writer (v0.13.0 P0, KNOWN-HAZARDS 7.17):** broker-side, every write to a hosted session's PTY goes through ONE per-session input-writer thread — the sole caller of the blocking `write_input`, fed by a bounded FIFO. All callers (operator keystrokes, message injection, the inject-floor flush) ENQUEUE and return immediately, so a paste burst that fills the harness input buffer parks only that thread, never the broker dispatch thread. A genuinely wedged harness (queue full) DROPS excess input + stamps the perc…\n\r\n**scrollback**:\r\nIn-memory ring buffer per session for v1. **On-disk spillover for long sessions is an intended, tracked feature** (deferred past v1, not forgotten) — see `docs/DEFERRED.md`.\r\n\r\n**live activity buffer (session digest)**:\r\nA rolling, human-glanceable view of an endpoint's **recent context** — *what the agent did* (recent user turns + the agent output between them, with **tool-usage sprints collapsed**, e.g. `<endpoint_id> used: **Write** `dir/file.txt` · **Bash** `first ~25 cmd chars` · […]`) **and** *what spt fed the agent* (**context-injection** entries — session-start psyche download, echo-commune mirror, incoming owl messages — collapsed by default, expandable). One time-ordered, glanceable timeline. **How much** is shown (window depth, arg-truncation, sprint-collapse) is the adapter's declared preference, consumer-overridable — *not* a fixed spt-core count. Distinct from both the **raw scrollback ring** (unparsed bytes) and full **transcript history** (the conversation be…\n\r\n- **Source = normalized session logs, never PTY parsing** (revised 2026-06-12, Gateway grill — supersedes the ADR-0008 source mechanism). A TUI's PTY stream is a *rendering protocol*, not a content log: scroll/resize trigger full repaints (duplicate content), and semantic turn boundaries drown in repaint soup. The split: **render surfaces read the PTY** (the R-TERM raw byte ring, unchanged); **content surfaces read the logs**. The digest reads the **same session logs as the echo-commune** but through its **own adapter-declared extractor** (the `[digest]` seam — see below), not echo's opaque normalizer: one source, two extractors (echo wants rich/opaque records; the digest wants the contract). Presentation knobs (window depth, sprint-collapse, arg truncation)…\n- **Topology-independent.** Because the source is logs, the digest works for harness-hosted endpoints too — Claude Code's per-session JSONL is Path A's worked example. Freshness = file-watch + adapter hook nudges; harnesses with no usable logs push entries directly via **`api digest-entry`** (the Path-B-style door). Near-realtime tailing needs an *incremental* normalize story (design-phase concern: Path A's normalize-command was shaped for occasional pulls).\r\n- **Thread-spanning across session boundaries.** A live agent's identity persists across many harness *sessions* (a `/clear` or `/compact` rotates the harness `session_id` — see `api boundary` / **post-spawn seam** — while the endpoint identity and `parent_pid` anchor hold). The digest follows the **agent thread**, not a single session: its rolling window may bridge a boundary (the tail of session N and the head of session N+1 coexist until the old turns age out), so a glance right after a `/clear` still shows the agent mid-thread rather than empty. A session boundary is itself **represented distinctively** in the digest (a visible boundary marker, e.g. a `/clear` divider), so a reader sees that context reset *there* without losing the thread. (Heir to the s…\n- **Two access modes.** **Snapshot pull** — `spt endpoint digest <[subnet:]id[@node]>` returns the current structured buffer (a Shell/CLI/GUI on-demand render; feeds the frontend's \"latest session output\" pane; a Gateway's agent-window). **Structured-delta stream** — a subscriber (live Shell pane, GUI, Gateway) receives only *changes* (new turn, new tool entry, collapse update), keyed to log records, for resource-efficient near-realtime reflection. **Access is address-gated** — fetch/subscribe is allowed for anyone who can address the endpoint (visible + resolvable per the resolution policy), the same gate as messaging.\r\n- **\"Option (C)\" logging surface:** the digest may also be *persisted* (opt-in per-endpoint) as a coarse activity log appended to the native history store (Path B), on-boundary or periodic — off by default.\r\n- **Adapter-declared extraction (post-M9 milestone — reverses M9's \"no manifest seam\"):** M9 retired the PTY-parse engine and made the digest an on-demand projection over a published `{role,text,tool}` contract carried in `[history]`. That under-served real adapters: one normalizer cannot serve echo (opaque) and the digest (contract) at once, and a contract mismatch failed **silently**. So the digest gets its **own `[digest]` manifest seam** — an **imperative extractor** the adapter declares (its native log → the `{role, text, tool, ts}` contract; reads the same source files as `[history]` by default, own-source escape hatch), with **`api digest-entry`** as the always-available push fallback. **No declarative DSL** (anyone who could conform to a fixed format…\n- **Two-origin merge.** The digest interleaves two sources by `ts`: the adapter's **extracted log records** (agent activity) and spt's own **context-injection entries** (psyche download / echo mirror / owl message), which spt appends to the endpoint's `digest.log` (the existing Path-B sink — spt becomes an internal producer). The projection merges both newest-relevant within the window. **Deferred (no consumer yet):** the GUI collapse/expand of context-injection entries, the echo-commune-reads-the-digest delta loop, and the *autonomous file-watch freshness* nudge land with the milestones that own those surfaces; the data model (the `[digest]` seam, `ts`, the context-injection category, thread-spanning) lands now so the contract need not break again.\r\n\r\n_Avoid_: \"PTY digest\" (the superseded source mechanism); parsing agent content out of PTY bytes anywhere.\r\n\r","startLine":50,"lineNumbers":[50,null,295,null,362,null,380,381,382,383,384,385,386,387,388,389,390,391,392,393,394,395,396,397,398,399,400,401,402,403,404,405,406,407,408,409,410,411,412,413,414,415,416,417,418,419,420,421,422,423,424,425,426,427,428,429,430,431,432,433,434,435,436,437,438,439,440,441,442,443,444,445,446,447,448,449,450,451,452,453,454,455,456,457,458,459,460,461,462,463,464,465,466,467,468,469,470,471,472,473,474,475,476,477,478,479,480,481,482,483,484,485,486,487,488,489,490,491,492,493,494,495,496,497,498,499,500,501,502,503,504,505,506,507,508]},"meta":{"source":{"type":"path","value":"C:\\Users\\decid\\Documents\\projects\\spt-core\\CONTEXT.md"},"truncation":{"direction":"head","truncatedBy":"lines","totalLines":889,"totalBytes":25270,"outputLines":129,"outputBytes":25270,"shownRange":{"start":380,"end":508},"nextOffset":509},"limits":{"columnTruncated":{"maxColumn":768}}}},"isError":false,"timestamp":1784434350166}}

Instead build the struct DIRECTLY in-test (fields crate-private, test is in-module via `super::*`): `InputWriter { tx, backpressure: AtomicBool::new(false), endpoint: String::new(), _writer: thread::spawn(|| {}) }`. Keep `rx` in the test so YOU are the consumer (drain by hand) — deterministic, zero wall-clock.\n 14|- `endpoint: String::new()` makes `stamp_backpressure` a no-op (`if self.endpoint.is_empty() { return; }`), so DROP/HEAL unit asserts read the in-crate `backpressure` atomic directly — hermetic, no perch.\n*15|- Drain ORDER: `input_writer` is a trivial `while let Ok(b)=rx.recv(){ surface.write_input(&b) }` loop — replicate it against a stub `SessionSurface` (impl `spt_term::surface::{SessionSurface,SurfaceError,SurfaceSize}`, push to a shared Vec) to assert FIFO order. Use a NON-monotonic byte sequence so a sort/reorder mutation is caught, not just reverse.\n 16|- Exactly-once: `crate::effect::{EffectJournal,EffectKind::PtyWrite,Outcome}` — `apply_once(key, PtyWrite, || { w.enqueue(..); Ok(()) })` then replay same key ⇒ `Deduped`, drain FIFO ⇒ bytes present exactly once. Mirrors effect.rs idempotency patterns.\n 17|\n 18|**How to apply (int — `tests/inject_control_wedge.rs`):**\n...\n 20|- DROP+backpressure: set `SPT_INPUT_QUEUE_DEPTH=4` BEFORE `spawn_session` (read at `InputWriter::spawn`), and REMOVE it IMMEDIATELY AFTER spawn (the env is process-global; a mid-test assert-panic would otherwise leak a depth-4 FIFO into later tests in the same binary under `--test-threads=1`, mis-dropping their input). Defensive remove at teardown too.\n*21|- Read the operator-visible signal via `spt_store::info::read_info(perch).input_backpressure` (Option<bool>). You MUST seed the perch first (`create_dir_all` + `InfoJson::new(endpoint,\"<ts>\",0,\"\",\"online\")` + `write_info`) — `set_input_backpressure` no-ops when the record is absent, exactly like `stamp_driven_by` (the W5-A2 rig artifact). Path = `resolve_perch_path(endpoint, ParentHint::Infer)` under the test `SPT_HOME` (set by `init_wedge_home`).\n 22|- Platform divergence (the file's banked stance): forkpty (Unix) genuinely PARKS `write_input` → HARD-assert subscribed/got_output/keystroke + `#[cfg(unix)]` backpressure. Windows ConPTY ABSORBS → CAPTURE backpressure (don't false-red).

Defensive remove at teardown too.\n*21│- Read the operator-visible signal via `spt_store::info::read_info(perch).input_backpressure` (Option<bool>). You MUST seed the perch first (`create_dir_all` + `InfoJson::new(endpoint,\"<ts>\",0,\"\",\"online\")` + `write_info`) — `set_input_backpressure` no-ops when the record is absent, exactly like `stamp_driven_by` (the W5-A2 rig artifact). Path = `resolve_perch_path(endpoint, ParentHint::Infer)` under the test `SPT_HOME` (set by `init_wedge_home`).\n 22│- Platform divergence (the file's banked stance): forkpty (Unix) genuinely PARKS `write_input` → HARD-assert subscribed/got_output/keystroke + `#[cfg(unix)]` backpressure. Windows ConPTY ABSORBS → CAPTURE backpressure (don't false-red).

Helper `controller_socket_pair()` returns `(SharedSend, client Stream, RecvHalf)`; hold the RecvHalf so the server fd stays open.\n*12│- **DETERMINISM LEVER (load-bearing):** hold `send.lock()` (the guard) ACROSS both `become_controller(from_seq=1)` then `(from_seq=0)` calls, THEN `drop(guard)`. This parks both writer threads on the socket mutex until after the epoch bump, so whichever writer next wins the lock reads the bumped epoch and (post-fix) bails.

Adding a new field to `DaemonConfig` breaks any full-struct-literal test (e.g. `save_load_roundtrip`) with E0063 — update those literals (or use `..DaemonConfig::default()`); most sibling tests already use `..default()`.\n 15│\n*16│**CAUTION (from operator memory):** never run the unfiltered `spt-daemon --lib` suite on this live host — seedmap/serveprobe/shellwake deadlock when live daemons share the Windows host.

Later CUP/EL/ECH/ICH/DCH operations address physical terminal columns but mutate this under-width logical row. A concrete deterministic shape explains the fragments: after two display-width-2 glyphs, the model is two cells behind the physical terminal; an absolute CUP to the physical start of `Tools`/`Where`/`Escape` followed by EL indexes two logical cells too far right, preserving the first two ASCII characters — exactly `To`/`Wh`/`Es`. `render_repaint` clears the client first, so it cannot preserve pre-existing physical garbage; it can, however, faithfully repaint those scraps from its already-corrupted model and place another row two columns left. This path affects a cold attach/repaint; live frames are forwarded raw before the grid is advanced, so a no-attach/no-repaint occurrence would require a different path.\n\nThe CPR/DSR path is a separate, real protocol defect/contamination risk. Timeline: (1) Claude Code or ConPTY emits `ESC[6n` on PTY output; (2) `spt-term`’s drain matcher writes the hard-coded CPR `ESC[1;1R` directly to the PTY writer; (3) only after that write does it call `sink(chunk)`; (4) the original `ESC[6n` remains in the output chunk, is retained/fanned out by the broker, carried as `AttachRecord::Output`, and written verbatim by rc to the physical terminal; (5) a real terminal may answer with its actual CPR; (6) rc has no terminal-reply discriminator, so its stdin reader treats that response like operator input and sends it through `AttachRecord::Input` → target `serve_attach` → broker PTY input. The child can therefore receive a guaranteed first, inaccurate `1;1` CPR plus a delayed physical-terminal CPR. The existing unit test explicitly asserts both halves: exactly one fixed reply is written and the query is forwarded unchanged. `ScreenGrid::csi_dispatch` has no `n` arm and does not answer DSR, so DSR does not directly mutate the server grid. [INFERENCE] A wrong/double CPR can perturb Claude Code’s own cursor state and should be fixed/tested, but source alone does not make it the direct wrap/scrap mechanism; the exact two-cell/prefix signature maps more tightly to the missing continuation cells.\n\nA second DSR-shaped input source exists only on idle-message injection: broker `settle_before_inject` enqueues `ESC[6n` directly into child input as a readiness probe. That is the reverse direction from a terminal DSR query and is indistinguishable from a CSI key sequence to a raw-mode TUI. It can contaminate child input around an injected delivery, but it is not exercised merely by rc attach/resize and cannot explain the screenshot without a temporally coincident idle delivery.\n\nRuled paths: current main cannot render the legacy rc identity overlay because `STATUS_ROW_ENABLED` is `false` and `status_row_active` therefore returns false for controllers and viewers; when historically enabled it subtracted one PTY row only, never columns. A visible identity banner is evidence of an older running binary or stale terminal content, not current-main overlay wiring. Current resize routing preserves `(cols, rows)` correctly, sends `(rows, cols)` to the PTY, and performs no two-column subtraction. Current final-output ordering waits for drain quiescence and enqueues Exit behind queued Output, while display teardown runs only when the viewport ends; neither explains a stable live settings-row shift.\n\nDeterministic regressions: (A) add a stateful ScreenGrid contract using captured/minimized settings-frame bytes: paint three rows containing two width-2 glyphs before `Tools`, `Where`, and `Escape`; issue the same absolute CUP + EL/ECH/overwrite operations the TUI uses; synthesize `render_repaint`; apply it and one subsequent raw frame to a width-aware reference emulator. Assert server/reference cell equality, no `To`/`Wh`/`Es`, and exact row columns. Also cover one width-2 glyph, two width-2 glyphs (the screenshot’s exact delta), combining marks, overwrite/erase/ICH/DCH, wrap at the final column, and resize. The test must compare cell geometry, not repaint strings. (B) add a PTY/attach DSR loop test: scripted child paints to a known non-`1;1` cursor and emits a chunk-split `ESC[6n`; a fake terminal frontend observes output and supplies the correct CPR. Assert the child receives exactly one accurate CPR, the query cannot be answered by both server and frontend, and ordinary bytes remain ordered. Run it through the production drain → broker Output → attach/rc-input seam; a lower unit can first pin query consumption/filtering across chunk boundaries. (C) separately feed the idle settle probe into a raw-mode fixture and assert readiness traffic is not surfaced as application keystrokes/text.","files":[{"path":"crates/spt-term/src/screen.rs","description":"Primary screenshot seam. `Cell` at lines 122–145 has only `{ ch, pen }`; `GridState::put_char` at lines 327–344 advances one column per Unicode scalar.

(1) The child writes VT bytes into a daemon-owned ConPTY/forkpty. (2) `spt-term::Drain` reads the PTY; today it also acts as an unconditional DSR responder, writing fixed CPR directly back to PTY input while preserving the query in output. (3) broker `OutputLog` sequences/retains/fans raw bytes and advances one authoritative `ScreenGrid`; cold attaches receive `ScreenGrid::render_repaint`, while existing live attaches receive raw bytes. (4) target `serve_attach` translates broker events to `AttachRecord`; operator rc writes Output to its real terminal and sends all stdin back as Input. No protocol ownership boundary distinguishes terminal-generated replies from human keystrokes. (5) the physical terminal emulator finally interprets live VT and may itself answer forwarded queries. Consequently, two independent invariants are missing: the authoritative grid must model terminal cells (including wide-glyph continuation and combining behavior), and exactly one terminal-query responder must own DSR with accurate geometry. The screenshot’s two-cell/prefix pattern lands at the first invariant; the current DSR route is a separate confirmed double-response/input-contamination

verdict: the highest-confidence mechanism for the screenshot’s exact two-column displacement and the two-character scraps (`To`, `Wh`, `Es`) is the server `ScreenGrid`’s missing wide-glyph/continuation-cell model, not rc’s status overlay and not final-output ordering. `Cell` stores only one Unicode scalar plus pen, with no continuation/combining state, and `GridState::put_char` advances exactly one column for every `char`. Later CUP/EL/ECH/ICH/DCH operations address physical terminal columns but mutate this under-width logical row. A concrete deterministic shape explains the fragments: after two display-width-2 glyphs, the model is two cells behind the physical terminal; an absolute CUP to the physical start of `Tools`/`Where`/`Escape` followed by EL indexes two logical cells too far right, preserving the first two ASCII characters — exactly `To`/`Wh`/`Es`. `render_repaint` clears the client first, so it cannot preserve pre-existing physical garbage; it can, however, faithfully repaint those scraps from its already-corrupted model and place another row two columns left. This path affects a cold attach/repaint; live frames are forwarded raw before the grid is advanced, so a no-attach/no-repaint occurrence would require a different path.\\n\\nThe CPR/DSR path is a separate, real protocol defect/contamination risk. Timeline: (1) Claude Code or ConPTY emits `ESC[6n` on PTY output; (2) `spt-term`’s drain matcher writes the hard-coded CPR `ESC[1;1R` directly to the PTY writer; (3) only after that write does it call `sink(chunk)`; (4) the original `ESC[6n` remains in the output chunk, is retained/fanned out by the broker, carried as `AttachRecord::Output`, and written verbatim by rc to the physical terminal; (5) a real terminal may answer with its actual CPR; (6) rc has no terminal-reply discriminator, so its stdin reader treats that response like operator input and sends it through `AttachRecord::Input` → target `serve_attach` → broker PTY input. The child can therefore receive a guaranteed first, inaccurate `1;1` CPR plus a delayed physical-terminal CPR. The existing unit test explicitly asserts both halves: exactly one fixed reply is written and the query is forwarded unchanged. `ScreenGrid::csi_dispatch` has no `n` arm and does not answer DSR, so DSR does not directly mutate the server grid. [INFERENCE] A wrong/double CPR can perturb Claude Code’s own cursor state and should be fixed/tested, but source alone does not make it the direct wrap/scrap mechanism; the exact two-cell/prefix signature maps more tightly to the missing continuation cells.\\n\\nA second DSR-shaped input source exists only on idle-message injection: broker `settle_before_inject` enqueues `ESC[6n` directly into child input as a readiness probe. That is the reverse direction from a terminal DSR query and is indistinguishable from a CSI key sequence to a raw-mode TUI. It can contaminate child input around an injected delivery, but it is not exercised merely by rc attach/resize and cannot explain the screenshot without a temporally coincident idle delivery.\\n\\nRuled paths: current main cannot render the legacy rc identity overlay because `STATUS_ROW_ENABLED` is `false` and `status_row_active` therefore returns false for controllers and viewers; when historically enabled it subtracted one PTY row only, never columns. A visible identity banner is evidence of an older running binary or stale terminal content, not current-main overlay wiring. Current resize routing preserves `(cols, rows)` correctly, sends `(rows, cols)` to the PTY, and performs no two-column subtraction. Current final-output ordering waits for drain quiescence and enqueues Exit behind queued Output, while display teardown runs only when the viewport ends; neither explains a stable live settings-row shift.\\n\\nDeterministic regressions: (A) add a stateful ScreenGrid contract using captured/minimized settings-frame bytes: paint three rows containing two width-2 glyphs before `Tools`, `Where`, and `Escape`; issue the same absolute CUP + EL/ECH/overwrite operations the TUI uses; synthesize `render_repaint`; apply it and one subsequent raw frame to a width-aware reference emulator. Assert server/reference cell equality, no `To`/`Wh`/`Es`, and exact row columns. Also cover one width-2 glyph, two width-2 glyphs (the screenshot’s exact delta), combining marks, overwrite/erase/ICH/DCH, wrap at the final column, and resize. The test must compare cell geometry, not repaint strings. (B) add a PTY/attach DSR loop test: scripted child paints to a known non-`1;1` cursor and emits a chunk-split `ESC[6n`; a fake terminal frontend observes output and supplies the correct CPR. Assert the child receives exactly one accurate CPR, the query cannot be answered by both server and frontend, and ordinary bytes remain ordered. Run it through the production drain → broker Output → attach/rc-input seam; a lower unit can first pin query consumption/filtering across chunk boundaries. (C) separately feed the idle settle probe into a raw-mode fixture and assert readiness traffic is not surfaced as application keystrokes/text.\",\"files\":[{\"path\":\"crates/spt-term/src/screen.rs\",\"description\":\"Primary screenshot seam. `Cell` at lines 122–145 has only `{ ch, pen }`; `GridState::put_char` at lines 327–344 advances one column per Unicode scalar.

(1) The child writes VT bytes into a daemon-owned ConPTY/forkpty.

(3) broker `OutputLog` sequences/retains/fans raw bytes and advances one authoritative `ScreenGrid`; cold attaches receive `ScreenGrid::render_repaint`, while existing live attaches receive raw bytes.

No protocol ownership boundary distinguishes terminal-generated replies from human keystrokes. (5) the physical terminal emulator finally interprets live VT and may itself answer forwarded queries. Consequently, two independent invariants are missing: the authoritative grid must model terminal cells (including wide-glyph continuation and combining behavior), and exactly one terminal-query responder must own DSR with accurate geometry.

(1) The child writes VT bytes into a daemon-owned ConPTY/forkpty. (2) `spt-term::Drain` reads the PTY; today it also acts as an unconditional DSR responder, writing fixed CPR directly back to PTY input while preserving the query in output. (3) broker `OutputLog` sequences/retains/fans raw bytes and advances one authoritative `ScreenGrid`; cold attaches receive `ScreenGrid::render_repaint`, while existing live attaches receive raw bytes. (4) target `serve_attach` translates broker events to `AttachRecord`; operator rc writes Output to its real terminal and sends all stdin back as Input. No protocol ownership boundary distinguishes terminal-generated replies from human keystrokes. (5) the physical terminal emulator finally interprets live VT and may itself answer forwarded queries. Consequently, two independent invariants are missing: the authoritative grid must model terminal cells (including wide-glyph continuation and combining behavior), and exactly one terminal-query responder must own DSR with accurate geometry. The screenshot’s two-cell/prefix pattern lands at the first invariant; the current DSR route is a separate confirmed double-response/input-contamination seam."},"status":"success","type":"result"},"isError":false,"timestamp":1784434647927}}
