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

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: **Terminal Overlay Investigator**.

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.

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.

Refuse to give up.**\r\n\r\n### Ways to construct one — try them in roughly this order\r\n\r\n1. **Failing test** at whatever seam reaches the bug — unit, integration, e2e.\r\n2. **Curl / HTTP script** against a running dev server.\r\n3. **CLI invocation** with a fixture input, diffing stdout against a known-good snapshot.\r\n4. **Headless browser script** (Playwright / Puppeteer) — drives the UI, asserts on DOM/console/network.\r\n5. **Replay a captured trace.** Save a real network request / payload / event log to disk; replay it through the code path in isolation.\r\n6. **Throwaway harness.** Spin up a minimal subset of the system (one service, mocked deps) that exercises the bug code path with a single function call.\r\n7. **Property / fuzz loop.** If the bug is \"sometimes wrong output\", run 1000 random inputs and look for the failure mode.\r\n8. **Bisection harness.** If the bug appeared between two known states (commit, dataset, version), automate \"boot at state X, check, repeat\" so you can `git bisect run` it.\r\n9. **Differential loop.** Run the same input through old-version vs new-version (or two configs) and diff outputs.\r\n10. **HITL bash script.** Last resort. If a human must click, drive _them_ with `scripts/hitl-loop.template.sh` so the loop is still structured. Captured output feeds back to you.\r\n\r\nBuild the right feedback loop, and the bug is 90% fixed.\r\n\r\n### Iterate on the loop itself\r\n\r\nTreat the loop as a product. Once you have _a_ loop, ask:\r\n\r\n- Can I make it faster? (Cache setup, skip unrelated init, narrow the test scope.)\r\n- Can I make the signal sharper? (Assert on the specific symptom, not \"didn't crash\".)\r\n- Can I make it more deterministic? (Pin time, seed RNG, isolate filesystem, freeze network.)\r\n\r\nA 30-second flaky loop is barely better than no loop. A 2-second deterministic loop is a debugging superpower.\r\n\r\n### Non-deterministic bugs\r\n\r\nThe goal is not a clean repro but a **higher reproduction rate**. Loop the trigger 100×, parallelise, add stress, narrow timing windows, inject sleeps. A 50%-flake bug is debuggable; 1% is not — keep raising the rate until it's debuggable.\r\n\r\n### When you genuinely cannot build a loop\r\n\r\nStop and say so explicitly. List what you tried. Ask the user for: (a) access to whatever environment reproduces it, (b) a captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.\r\n\r\nDo not proceed to Phase 2 until you have a loop you believe in.\r\n\r\n## Phase 2 — Reproduce\r\n\r\nRun the loop. Watch the bug appear.\r\n\r\nConfirm:\r\n\r\n- [ ] The loop produces the failure mode the **user** described — not a different failure that happens to be nearby. Wrong bug = wrong fix.\r\n- [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).\r\n- [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.\r\n\r\nDo not proceed until you reproduce the bug.\r\n\r\n## Phase 3 — Hypothesise\r\n\r\nGenerate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.\r\n\r\nEach hypothesis must be **falsifiable**: state the prediction it makes.\r\n\r\n> Format: \"If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse.\"\r\n\r\nIf you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.\r\n\r\n**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly (\"we just deployed a change to #3\"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it — proceed with your ranking if the user is AFK.\r\n\r\n## Phase 4 — Instrument\r\n\r\nEach probe must map to a specific prediction from Phase 3. **Change one variable at a time.**\r\n\r\nTool preference:\r\n\r\n1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.\r\n2. **Targeted logs** at the boundaries that distinguish hypotheses.\r\n3. Never \"log everything and grep\".\r\n\r\n**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.\r\n\r\n**Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.\r\n\r\n## Phase 5 — Fix + regression test\r\n\r\nWrite the regression test **before the fix** — but only if there is a **correct seam** for it.\r\n\r\nA correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site. 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.\r\n\r\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.\r\n\r\nIf a correct seam exists:\r\n\r\n1. Turn the minimised repro into a failing test at that seam.\r\n2. Watch it fail.\r\n3. Apply the fix.\r\n4. Watch it pass.\r\n5. Re-run the Phase 1 feedback loop against the original (un-minimised) scenario.\r\n\r\n## Phase 6 — Cleanup + post-mortem\r\n\r\nRequired before declaring done:\r\n\r\n- [ ] Original repro no longer reproduces (re-run the Phase 1 loop)\r\n- [ ] Regression test passes (or absence of seam is documented)\r\n- [ ] All `[DEBUG-...]` instrumentation removed (`grep` the prefix)\r\n- [ ] Throwaway prototypes deleted (or moved to a clearly-marked debug location)\r\n- [ ] The hypothesis that turned out correct is stated in the commit / PR message — so the next debugger learns\r\n\r\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.\r\n","startLine":1,"lineNumbers":[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118]},"meta":{"source":{"type":"internal","value":"skill://diagnose"}}},"isError":false,"timestamp":1784434168038}}

This\n 219|  matters when installing a fresh adapter such as the Claude Code plugin.\n...\n 733|- **`spt adapter add` no longer swallows install errors.** Errors from the install-as-first-update step were discarded; the failing step's output is now surfaced, and the composite post-install step runs at install time.\n*734|- **`spt adapter update` no longer fails to re-register after fetching.** The update derived the install directory from the `[update]` repo name rather than the adapter's registered source directory — so after a repo rename it wrote to a fresh empty directory and then failed re-register with `os error 2`. Update now targets the registered source directory and tolerates a changed update repo.\n 735|- **`spt endpoint digest` now works for endpoints whose transcript lives under a relocated profile.** A profile that relocates the harness transcript tree (via a runtime env like `CLAUDE_CONFIG_DIR`) produced `NO_DIGEST` because the on-demand extractor ran without that environment. The digest path now carries the profile's transcript-location environment to the extractor, which locates and reads the transcript itself.\n 736|\n 737|## [0.18.0] - 2026-06-30\n...\n 775|\n*776|- **Composite adapter update — `[update.post]`.** A manifest can declare a delegated post-step that `spt adapter update` runs *after* the primary update avenue resolves, so one command both pulls the adapter's `.spt` (e.g. from a GitHub release) **and** runs an in-harness sync. The post-step runs unconditionally (even on an up-to-date no-op), reads a published JSON line on stdin describing the update, and its stdout decides the post-update notice. A post-step failure warns and falls back — it never r...\n 777|- **Global `--json` for status queries.** `endpoint list`/`whoami`, `daemon status`, `subnet status`/`show-code`, `endpoint description`/`role`, `adapter list`/`version`, `notif list`, `grant list`, `access list`, `shell list`, and `how-to` now accept a global `--json` flag emitting stable, explicit fields for scripted consumption. (Action commands ignore it.)\n 778|- **`spt endpoint digest` incremental cursor.** `--json` output gains `--last <N>` (the last N turns; `--last 1` is the latest turn), a stable per-entry `seq` that survives live re-projection and window slides, `--after <seq>` (only what is newer, with a full-refresh signal if the cursor fell out of the window), a `partial` flag on the in-progress turn, and a per-entry `ts` — so a consumer can process turn-ends incrementally instead of re-reading the whole window.\n 779|- **`spt rc` identity marker.** An attached controller now shows a persistent top status row — right-aligned `SUBNET : ENDPOINT_ID @ NODE` in cyan — so you always know which endpoint you are driving. It re-asserts across alt-screen, resize, and scroll-region resets.\n*780|- **Manifest substitution primitives.** Two adapter-static substitution keys — `{adapter_dir}` (the adapter's install dir, which survives updates) and `{adapter_name}` — are available wherever command/string substitution runs, and `[strings]` values are now substituted at `get-string` read time. This lets an adapter resolve a path to its own packed binary without spt-core ever executing it.\n 781|- **`[message-idle-translation-binary]` takes a `command`.** The idle-delivery translation binary can be declared with a `command` (program token plus args, with adapter-static substitution) instead of the bare `path`, so it can be invoked as a subcommand of a consolidated adapter binary. The spawn and stdin/stdout protocol are unchanged.\n 782|- **Empty-scope creation flow.** Running `spt endpoint run` (or bare `spt`) on a node with no endpoints at all now opens directly on the adapter-creation screen instead of an empty picker.\n 783|\n...\n 889|- **Pasting or typing into an spt-hosted endpoint no longer freezes the daemon.** A large paste or input burst could wedge the daemon's input path so every new attach died; input now runs on a dedicated per-session writer and never blocks the daemon (this also covers the effect-journal stall on interactive input).\n*890|- **Session resume actually resumes now.** Agent endpoints track session history and offer explicit session resume via `spt endpoint run` (`--resume <session>` or *Resume from history*); the adapter manifest can now declare a `[session.resume]` command so the relaunch reattaches the prior session instead of always starting a new one. The run picker now shows each row's working directory and local time.\n 891|- **`spt rc --view` viewers survive a high-output terminal.** A viewer no longer dies when the output backlog rolls over or it is briefly evicted — it snaps forward or skips to live instead of failing — and a slow controller can no longer starve a concurrent viewer.\n 892|- **`spt rc` no longer races a just-started agent.** Attach now waits for the endpoint to come online, instead of failing when you attach immediately after `spt endpoint run`.\n 893|- **The daemon no longer flashes or respawns a console window on Windows.**\n...\n 1026|- **Two new `spt how-to` guides: `subnet` and `live`.** Pairing machines (create vs join, the 6-digit code, reaching remote agents) and running as a live agent (the persistent `spt api listen` relay, the Psyche seam) now have task-oriented in-binary topics instead of dead-ending.\n*1027|- **Update an adapter from a GitHub release, optionally signature-checked.** An adapter's `[update]` feed can now be a GitHub release (`avenue = \"gh_release\"`); `spt adapter update` pulls the newer `.spt`. Declare a `signing_key` and verification is fail-closed — an unsigned or wrong-signature artifact is refused, not installed.\n 1028|- **`spt api` resolves an adapter's manifest and install directory from `--adapter`.** Pass `--adapter <name[:profile]>` without `--manifest` and spt looks both up from the registry; `--manifest` becomes an override for an unregistered or local manifest.\n 1029|\n 1030|### Fixed\n...\n 1188|  - `spt endpoint list --detail` adds each endpoint's description blurb.\n*1189|- **`spt endpoint description [set]`** — read or write an endpoint's description blurb (bare command shows it, `set` writes it).\n 1190|- **`spt endpoint access`** — per-endpoint access control (`allow` / `revoke` / `open` / `list`), scoped to the individual endpoint.\n 1191|- **`spt daemon` command group:**\n 1192|  - `spt daemon status` (or bare `spt daemon`) — a node status view: whether the daemon is running, its background-sync health, your subnets, and your local endpoints.\n\n# CI-SELFHOST-PLAN.md\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\n# CLAUDE.md\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`.

This\n  219│  matters when installing a fresh adapter such as the Claude Code plugin.\n     │...\n  733│- **`spt adapter add` no longer swallows install errors.** Errors from the install-as-first-update step were discarded; the failing step's output is now surfaced, and the composite post-install step runs at install time.\n *734│- **`spt adapter update` no longer fails to re-register after fetching.** The update derived the install directory from the `[update]` repo name rather than the adapter's registered source directory — so after a repo rename it wrote to a fresh empty directory and then failed re-register with `os error 2`. Update now targets the registered source directory and tolerates a changed update repo.\n  735│- **`spt endpoint digest` now works for endpoints whose transcript lives under a relocated profile.** A profile that relocates the harness transcript tree (via a runtime env like `CLAUDE_CONFIG_DIR`) produced `NO_DIGEST` because the on-demand extractor ran without that environment. The digest path now carries the profile's transcript-location environment to the extractor, which locates and reads the transcript itself.\n  736│\n  737│## [0.18.0] - 2026-06-30\n     │...\n  775│\n *776│- **Composite adapter update — `[update.post]`.** A manifest can declare a delegated post-step that `spt adapter update` runs *after* the primary update avenue resolves, so one command both pulls the adapter's `.spt` (e.g. from a GitHub release) **and** runs an in-harness sync. The post-step runs unconditionally (even on an up-to-date no-op), reads a published JSON line on stdin describing the update, and its stdout decides the post-update notice. A post-step failure warns and falls back — it never r...\n  777│- **Global `--json` for status queries.** `endpoint list`/`whoami`, `daemon status`, `subnet status`/`show-code`, `endpoint description`/`role`, `adapter list`/`version`, `notif list`, `grant list`, `access list`, `shell list`, and `how-to` now accept a global `--json` flag emitting stable, explicit fields for scripted consumption. (Action commands ignore it.)\n  778│- **`spt endpoint digest` incremental cursor.** `--json` output gains `--last <N>` (the last N turns; `--last 1` is the latest turn), a stable per-entry `seq` that survives live re-projection and window slides, `--after <seq>` (only what is newer, with a full-refresh signal if the cursor fell out of the window), a `partial` flag on the in-progress turn, and a per-entry `ts` — so a consumer can process turn-ends incrementally instead of re-reading the whole window.\n  779│- **`spt rc` identity marker.** An attached controller now shows a persistent top status row — right-aligned `SUBNET : ENDPOINT_ID @ NODE` in cyan — so you always know which endpoint you are driving. It re-asserts across alt-screen, resize, and scroll-region resets.\n *780│- **Manifest substitution primitives.** Two adapter-static substitution keys — `{adapter_dir}` (the adapter's install dir, which survives updates) and `{adapter_name}` — are available wherever command/string substitution runs, and `[strings]` values are now substituted at `get-string` read time. This lets an adapter resolve a path to its own packed binary without spt-core ever executing it.\n  781│- **`[message-idle-translation-binary]` takes a `command`.** The idle-delivery translation binary can be declared with a `command` (program token plus args, with adapter-static substitution) instead of the bare `path`, so it can be invoked as a subcommand of a consolidated adapter binary. The spawn and stdin/stdout protocol are unchanged.\n  782│- **Empty-scope creation flow.** Running `spt endpoint run` (or bare `spt`) on a node with no endpoints at all now opens directly on the adapter-creation screen instead of an empty picker.\n  783│\n     │...\n  889│- **Pasting or typing into an spt-hosted endpoint no longer freezes the daemon.** A large paste or input burst could wedge the daemon's input path so every new attach died; input now runs on a dedicated per-session writer and never blocks the daemon (this also covers the effect-journal stall on interactive input).\n *890│- **Session resume actually resumes now.** Agent endpoints track session history and offer explicit session resume via `spt endpoint run` (`--resume <session>` or *Resume from history*); the adapter manifest can now declare a `[session.resume]` command so the relaunch reattaches the prior session instead of always starting a new one. The run picker now shows each row's working directory and local time.\n  891│- **`spt rc --view` viewers survive a high-output terminal.** A viewer no longer dies when the output backlog rolls over or it is briefly evicted — it snaps forward or skips to live instead of failing — and a slow controller can no longer starve a concurrent viewer.\n  892│- **`spt rc` no longer races a just-started agent.** Attach now waits for the endpoint to come online, instead of failing when you attach immediately after `spt endpoint run`.\n  893│- **The daemon no longer flashes or respawns a console window on Windows.**\n     │...\n 1026│- **Two new `spt how-to` guides: `subnet` and `live`.** Pairing machines (create vs join, the 6-digit code, reaching remote agents) and running as a live agent (the persistent `spt api listen` relay, the Psyche seam) now have task-oriented in-binary topics instead of dead-ending.\n*1027│- **Update an adapter from a GitHub release, optionally signature-checked.** An adapter's `[update]` feed can now be a GitHub release (`avenue = \"gh_release\"`); `spt adapter update` pulls the newer `.spt`. Declare a `signing_key` and verification is fail-closed — an unsigned or wrong-signature artifact is refused, not installed.\n 1028│- **`spt api` resolves an adapter's manifest and install directory from `--adapter`.** Pass `--adapter <name[:profile]>` without `--manifest` and spt looks both up from the registry; `--manifest` becomes an override for an unregistered or local manifest.\n 1029│\n 1030│### Fixed\n     │...\n 1188│  - `spt endpoint list --detail` adds each endpoint's description blurb.\n*1189│- **`spt endpoint description [set]`** — read or write an endpoint's description blurb (bare command shows it, `set` writes it).\n 1190│- **`spt endpoint access`** — per-endpoint access control (`allow` / `revoke` / `open` / `list`), scoped to the individual endpoint.\n 1191│- **`spt daemon` command group:**\n 1192│  - `spt daemon status` (or bare `spt daemon`) — a node status view: whether the daemon is running, its background-sync health, your subnets, and your local endpoints.\n\n# CI-SELFHOST-PLAN.md\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\n# CLAUDE.md\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`.

KNOWN-HAZARDS 7.47. Prior art surveyed: herdr v0.7.4 (AGPL — design\n  ideas only, no code reuse without license review). Kin: ADR-0038 (stream lifecycle),\n  KH 7.43/7.44 (write-path substrate).\n\n## Context\n\nField symptom: stale glyphs and \"missing whitespace\" across picker and rc PTY surfaces.\nThere is NO shared whitespace-trimming defect — raw live PTY bytes (spaces, ANSI erases)\nare preserved end-to-end. The symptoms are distinct render-lifecycle failures with one\ncommon invariant violation: **the physical terminal is mutated or terminated outside its\nrenderer's ordered state model.**\n\n1. **Broker Exit overtakes final Output.** The exit waiter direct-writes `KIND_EXIT` via\n   `all_sinks()` while normal PTY output queues through `controller_writer`; the\n   per-connection gate serializes writes but does not impose producer order. `serve_attach`\n   returns immediately on Exit; rc returns immediately on that record. A final erase, SGR\n   reset, cursor-show, DECSTBM reset, or `?1049l` can be stranded. The race is already\n   admitted in the broker test suite (the env-echo test documents that EXIT can arrive\n   before OUTPUT and compensates by post-exit draining) — production rc has no such\n   compensation.\n2. **rc never unconditionally restores display state.** `RawGuard::drop` restores input\n   raw mode, mouse capture, and the Windows console output mode — it does not reset\n   child-controlled VT display state. Every final path (detach, child exit, displacement,\n   first-event stall, fatal error, reconnect give-up) can leave alt-screen/cursor/SGR/\n   scroll-region dirty; the reconnect banner clears+homes and the give-up prints at the\n   centered cursor with no final reset.\n3. **Picker invalidates ratatui's diff baseline with out-of-band stderr.** Purge runs\n   inline while the TUI owns the alternate screen; the purge core writes diagnostics to\n   stderr, mutating the physical screen without updating ratatui's previous Buffer. The\n   next draw correctly emits only model diffs; cells ratatui believes blank are skipped —\n   stderr glyph fragments persist. (Unrelated to ScreenGrid.)\n4. **Cold repaint omits tracked modes.** ScreenGrid tracks DECSTBM margins but\n   `render_repaint` never replays them; client and server grids then interpret subsequent\n   raw scrolling against different regions. (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.

KNOWN-HAZARDS 7.47. Prior art surveyed: herdr v0.7.4 (AGPL — design\n  ideas only, no code reuse without license review). Kin: ADR-0038 (stream lifecycle),\n  KH 7.43/7.44 (write-path substrate).\n\n## Context\n\nField symptom: stale glyphs and \"missing whitespace\" across picker and rc PTY surfaces.\nThere is NO shared whitespace-trimming defect — raw live PTY bytes (spaces, ANSI erases)\nare preserved end-to-end. The symptoms are distinct render-lifecycle failures with one\ncommon invariant violation: **the physical terminal is mutated or terminated outside its\nrenderer's ordered state model.**\n\n1. **Broker Exit overtakes final Output.** The exit waiter direct-writes `KIND_EXIT` via\n   `all_sinks()` while normal PTY output queues through `controller_writer`; the\n   per-connection gate serializes writes but does not impose producer order. `serve_attach`\n   returns immediately on Exit; rc returns immediately on that record. A final erase, SGR\n   reset, cursor-show, DECSTBM reset, or `?1049l` can be stranded. The race is already\n   admitted in the broker test suite (the env-echo test documents that EXIT can arrive\n   before OUTPUT and compensates by post-exit draining) — production rc has no such\n   compensation.\n2. **rc never unconditionally restores display state.** `RawGuard::drop` restores input\n   raw mode, mouse capture, and the Windows console output mode — it does not reset\n   child-controlled VT display state. Every final path (detach, child exit, displacement,\n   first-event stall, fatal error, reconnect give-up) can leave alt-screen/cursor/SGR/\n   scroll-region dirty; the reconnect banner clears+homes and the give-up prints at the\n   centered cursor with no final reset.\n3. **Picker invalidates ratatui's diff baseline with out-of-band stderr.** Purge runs\n   inline while the TUI owns the alternate screen; the purge core writes diagnostics to\n   stderr, mutating the physical screen without updating ratatui's previous Buffer. The\n   next draw correctly emits only model diffs; cells ratatui believes blank are skipped —\n   stderr glyph fragments persist. (Unrelated to ScreenGrid.)\n4. **Cold repaint omits tracked modes.** ScreenGrid tracks DECSTBM margins but\n   `render_repaint` never replays them; client and server grids then interpret subsequent\n   raw scrolling against different regions. (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`).

It re-asserts across alt-screen, resize, and scroll-region resets.\n 780|- **Manifest substitution primitives.** Two adapter-static substitution keys — `{adapter_dir}` (the adapter's install dir, which survives updates) and `{adapter_name}` — are available wherever command/string substitution runs, and `[strings]` values are now substituted at `get-string` read time. This lets an adapter resolve a path to its own packed binary without spt-core ever executing it.\n 781|- **`[message-idle-translation-binary]` takes a `command`.** The idle-delivery translation binary can be declared with a `command` (program token plus args, with adapter-static substitution) instead of the bare `path`, so it can be invoked as a subcommand of a consolidated adapter binary. The spawn and stdin/stdout protocol are unchanged.\n 782|- **Empty-scope creation flow.** Running `spt endpoint run` (or bare `spt`) on a node with no endpoints at all now opens directly on the adapter-creation screen instead of an empty picker.\n...\n 1101|- **Adapter profiles — customize an adapter without forking it.** `spt adapter create-profile <adapter> <name>` makes a named variant of an installed adapter (its own environment, prompts, and capabilities); launch it by addressing `adapter:name`. A profile you create locally **survives updating or re-adding** the underlying adapter, and `spt adapter list` shows each profile as its own spawnable option. `spt adapter delete-profile` removes one. (A profile may only *tighten* what the adapter allows — ...\n*1102|- **Adapter config values.** `spt adapter set-string <adapter> <key> <value>` and `spt adapter get-string <adapter> <key>` read and write an adapter's named settings — per-profile when you address a profile.\n 1103|- **Keyword hints.** An adapter can teach its own commands in context: when a keyword it declares appears in one of your messages, a one-line tip surfaces — at most once per session, so it never nags.\n 1104|- **`spt endpoint role` — a durable agent role.** Set a free-form statement of what an endpoint is for; it is shown to the agent **first**, at the start of every new session. `spt endpoint role` is the only thing that writes it — nothing automated ever overwrites your wording.\n 1105|- **`spt api digest-entry`** lets a harness with no readable session log feed its activity directly, so even those sessions show a live digest.\n...\n 1108|\n*1109|- **The live session digest now works for any session, not just terminal-hosted ones.** `spt endpoint digest <id>` builds its at-a-glance view from a session's normalized logs instead of scraping the raw terminal stream — so a session spt-core doesn't host in its own terminal (for example a Claude Code session) now shows a digest too. `--follow` still streams changes as they happen.\n 1110|  - **Breaking (adapter authors):** the `[pty_digest]` manifest section is **removed**. The digest now rides your `[history]` source — emit your history records as `{\"role\": …, \"text\": …, \"tool\": …}` JSON (or push them with `spt api digest-entry`) and the digest builds itself. No digest-specific manifest section is needed.\n 1111|- **Messages now carry who sent them — a person or an agent.** A message you send is delivered marked as user-sent, and the daemon re-stamps anything that falsely claims to be from a user. A human-backed **Gateway** endpoint is accepted as a first-class endpoint — addressable, able to own shells, and able to subscribe to digests — including from another machine on your subnet.\n 1112|\n\n# docs/\n## CONTEXT-MEMORY.md\n 11|\n*12|### The discriminator (applied per *topic*, not per fragment)\n 13|\n 14|> **\"Would this still be true and relevant if the user opened a *different* project tomorrow?\"** Yes → live.

Promotion needs justification; demotion is free. The bias points against the leak.\n 21|2. **`current focus / next steps` is project-scoped** — the single biggest leak category. Route it to project unless the focus genuinely spans projects.\n 22|3. **Live holds a thin project roster, never project depth** — cross-project *awareness* travels; depth stays per-project.\n 23|4. **Commune-source asymmetry** (the structural fix): the live signal is strong only from **Self-authored communes**; **echo communes are project-centric** (they synthesize project-heavy session logs). So **echo communes are project-context-primary and live-context-conservative** — they make few/no live edits. This kills the leak at its source. Provenance is recorded on each block (`Source:`).\n...\n 44|\n*45|memformat goes from a decorative, ignored seed to the **load-bearing schema that defines the two-tier context**. It makes the live/project decision **per-topic and rare** instead of per-fragment and constant — which is what makes the split stable.\n 46|\n*47|- **Tier-tagged topics.** Each topic carries a tier: `live` or `project`. The tier is decided **once, when the topic is created** (apply the discriminator one time), not per fragment. Communes then just *fill* topics; the tier routes content to the right context file + sync tier. The two-slice envelope (`<live-context>`/`<project-context>`) becomes the *rendering* of tier-tagged topics.\n 48|- **Self-evolving.** The Psyche adds/removes/re-tiers topics as it learns Self's realm of work (memformat's original intent). **Re-tiering migrates** the topic's accumulated content between tiers (project→live or vice versa), not forward-only.\n 49|- **The schema is live** (per-agent, travels everywhere); **project-tagged topic content** is instantiated per-project.\n 50|- Example tiers: `identity / relationship / user-preferences / cross-project-learnings / project-roster` = **live**; `focus / decisions / architecture / todos / blockers` = **project**.\n## DOCS-STRATEGY.md\n 146|\n*147|Top-level `--help` groups by audience (`AGENT COMMANDS` send/ring/ready/poll · `HARNESS COMMANDS` api … · `NODE COMMANDS` pair/subnet/update).

It re-asserts across alt-screen, resize, and scroll-region resets.\n  780│- **Manifest substitution primitives.** Two adapter-static substitution keys — `{adapter_dir}` (the adapter's install dir, which survives updates) and `{adapter_name}` — are available wherever command/string substitution runs, and `[strings]` values are now substituted at `get-string` read time. This lets an adapter resolve a path to its own packed binary without spt-core ever executing it.\n  781│- **`[message-idle-translation-binary]` takes a `command`.** The idle-delivery translation binary can be declared with a `command` (program token plus args, with adapter-static substitution) instead of the bare `path`, so it can be invoked as a subcommand of a consolidated adapter binary. The spawn and stdin/stdout protocol are unchanged.\n  782│- **Empty-scope creation flow.** Running `spt endpoint run` (or bare `spt`) on a node with no endpoints at all now opens directly on the adapter-creation screen instead of an empty picker.\n     │...\n 1101│- **Adapter profiles — customize an adapter without forking it.** `spt adapter create-profile <adapter> <name>` makes a named variant of an installed adapter (its own environment, prompts, and capabilities); launch it by addressing `adapter:name`. A profile you create locally **survives updating or re-adding** the underlying adapter, and `spt adapter list` shows each profile as its own spawnable option. `spt adapter delete-profile` removes one. (A profile may only *tighten* what the adapter allows — ...\n*1102│- **Adapter config values.** `spt adapter set-string <adapter> <key> <value>` and `spt adapter get-string <adapter> <key>` read and write an adapter's named settings — per-profile when you address a profile.\n 1103│- **Keyword hints.** An adapter can teach its own commands in context: when a keyword it declares appears in one of your messages, a one-line tip surfaces — at most once per session, so it never nags.\n 1104│- **`spt endpoint role` — a durable agent role.** Set a free-form statement of what an endpoint is for; it is shown to the agent **first**, at the start of every new session. `spt endpoint role` is the only thing that writes it — nothing automated ever overwrites your wording.\n 1105│- **`spt api digest-entry`** lets a harness with no readable session log feed its activity directly, so even those sessions show a live digest.\n     │...\n 1108│\n*1109│- **The live session digest now works for any session, not just terminal-hosted ones.** `spt endpoint digest <id>` builds its at-a-glance view from a session's normalized logs instead of scraping the raw terminal stream — so a session spt-core doesn't host in its own terminal (for example a Claude Code session) now shows a digest too. `--follow` still streams changes as they happen.\n 1110│  - **Breaking (adapter authors):** the `[pty_digest]` manifest section is **removed**. The digest now rides your `[history]` source — emit your history records as `{\"role\": …, \"text\": …, \"tool\": …}` JSON (or push them with `spt api digest-entry`) and the digest builds itself. No digest-specific manifest section is needed.\n 1111│- **Messages now carry who sent them — a person or an agent.** A message you send is delivered marked as user-sent, and the daemon re-stamps anything that falsely claims to be from a user. A human-backed **Gateway** endpoint is accepted as a first-class endpoint — addressable, able to own shells, and able to subscribe to digests — including from another machine on your subnet.\n 1112│\n\n# docs/\n## CONTEXT-MEMORY.md\n 11│\n*12│### The discriminator (applied per *topic*, not per fragment)\n 13│\n 14│> **\"Would this still be true and relevant if the user opened a *different* project tomorrow?\"** Yes → live.

Route it to project unless the focus genuinely spans projects.\n 22│3. **Live holds a thin project roster, never project depth** — cross-project *awareness* travels; depth stays per-project.\n 23│4. **Commune-source asymmetry** (the structural fix): the live signal is strong only from **Self-authored communes**; **echo communes are project-centric** (they synthesize project-heavy session logs). So **echo communes are project-context-primary and live-context-conservative** — they make few/no live edits. This kills the leak at its source. Provenance is recorded on each block (`Source:`).\n   │...\n 44│\n*45│memformat goes from a decorative, ignored seed to the **load-bearing schema that defines the two-tier context**. It makes the live/project decision **per-topic and rare** instead of per-fragment and constant — which is what makes the split stable.\n 46│\n*47│- **Tier-tagged topics.** Each topic carries a tier: `live` or `project`. The tier is decided **once, when the topic is created** (apply the discriminator one time), not per fragment. Communes then just *fill* topics; the tier routes content to the right context file + sync tier. The two-slice envelope (`<live-context>`/`<project-context>`) becomes the *rendering* of tier-tagged topics.\n 48│- **Self-evolving.** The Psyche adds/removes/re-tiers topics as it learns Self's realm of work (memformat's original intent). **Re-tiering migrates** the topic's accumulated content between tiers (project→live or vice versa), not forward-only.\n 49│- **The schema is live** (per-agent, travels everywhere); **project-tagged topic content** is instantiated per-project.\n 50│- Example tiers: `identity / relationship / user-preferences / cross-project-learnings / project-roster` = **live**; `focus / decisions / architecture / todos / blockers` = **project**.\n## DOCS-STRATEGY.md\n 146│\n*147│Top-level `--help` groups by audience (`AGENT COMMANDS` send/ring/ready/poll · `HARNESS COMMANDS` api … · `NODE COMMANDS` pair/subnet/update).

Output drain pump — the ConPTY-DSR auto-answer reader (M3a A2).\n//!\n//! ConPTY can emit a cursor-position query `ESC [ 6 n` and **withhold all child\n//! stdout until the terminal answers it** (Spike #1: a run captured exactly the\n//! 4 bytes `\\e[6n` and zero program output — the child looked dead but was\n//! ticking fine; replying `ESC [ 1;1 R` immediately unblocked the full stream).\n//! Whether the query fires is build- and program-dependent (some ConPTY versions\n//! never emit it for short commands; an app that queries DSR itself always\n//! will). A real terminal *is* expected to answer DSR regardless, so the pump\n//! answers every `ESC[6n` it sees on every platform unconditionally — harmless\n//! correct CPR on the Unix raw-pipe backend, and the stall-breaker on any ConPTY\n//! that does withhold. The auto-answer is verified deterministically by injecting\n//! a synthetic DSR query (it must not depend on the host's ConPTY emitting one).\n//!\n//! **No-EOF-while-writer-held (Spike #1 secondary gotcha):** a ConPTY master\n//! does *not* EOF while the writer is held, so the read loop runs on its own\n//! thread and shutdown **never gates on a blocking `read()` returning**. The\n//! broker stops a surface by terminating the child (which tears the PTY down and\n//! unblocks the read); the [`Drain`] stop flag is a cooperative secondary signal\n//! observed whenever a read does return.

Output drain pump — the ConPTY-DSR auto-answer reader (M3a A2).\n//!\n//! ConPTY can emit a cursor-position query `ESC [ 6 n` and **withhold all child\n//! stdout until the terminal answers it** (Spike #1: a run captured exactly the\n//! 4 bytes `\\e[6n` and zero program output — the child looked dead but was\n//! ticking fine; replying `ESC [ 1;1 R` immediately unblocked the full stream).\n//! Whether the query fires is build- and program-dependent (some ConPTY versions\n//! never emit it for short commands; an app that queries DSR itself always\n//! will). A real terminal *is* expected to answer DSR regardless, so the pump\n//! answers every `ESC[6n` it sees on every platform unconditionally — harmless\n//! correct CPR on the Unix raw-pipe backend, and the stall-breaker on any ConPTY\n//! that does withhold. The auto-answer is verified deterministically by injecting\n//! a synthetic DSR query (it must not depend on the host's ConPTY emitting one).\n//!\n//! **No-EOF-while-writer-held (Spike #1 secondary gotcha):** a ConPTY master\n//! does *not* EOF while the writer is held, so the read loop runs on its own\n//! thread and shutdown **never gates on a blocking `read()` returning**.

HIGH — `ScreenGrid` has no wide-glyph continuation-cell model, and this is the strongest exact mechanism for the screenshot’s two-character left-margin scraps. `crates/spt-term/src/screen.rs:122-145` defines each cell as only `{ ch: char, pen: Pen }`. `GridState::put_char` at `screen.rs:330-349` advances exactly one grid column per Unicode scalar, regardless of terminal display width. The erase/edit paths at `screen.rs:359-443` likewise operate on those scalar cells. `crates/spt-term/Cargo.toml` depends on `vte` but not on a Unicode-width/grapheme implementation. `GridState::render_repaint` at `screen.rs:577-629` then emits the stored cells sequentially from an absolute `CUP row;1`. Consequently, a width-2 glyph occupies one authoritative grid cell but two cells in the real terminal; absolute cursor-addressed updates and synthesized repaint disagree by one column per wide glyph.\n\nDeterministic byte-level reproducer for the wrap/scrap class, using a 3-row × 10-column terminal:\n\n```text\nChild frame fed to ScreenGrid:\nESC [ 1 ; 1 H  界 界  ESC [ 1 ; 5 H  A B C D T o  ESC [ 3 ; 1 H  Search\n\nEscaped:\n\\x1b[1;1H界界\\x1b[1;5HABCDTo\\x1b[3;1HSearch\n\nHex for each 界: e7 95 8c\nCUP bytes: 1b 5b 31 3b 31 48 and 1b 5b 31 3b 35 48\n```\n\nA width-aware VT renders the child frame correctly: the two `界` glyphs occupy columns 1–4 and `ABCDTo` occupies columns 5–10; row 2 stays blank and `Search` begins on row 3. Current `ScreenGrid` instead stores the two glyphs in logical cells 1–2, leaves logical cells 3–4 blank, and stores `ABCDTo` in cells 5–10. The cold-attach repaint therefore emits the visible row as:\n\n```text\n界界··ABCDTo\n```\n\nwhere `··` are the two erroneous stored blank cells. That byte string has physical display width 12. On a 10-column terminal, `To` wraps to row 2, columns 1–2. `render_repaint` skips the authoritative grid’s default-blank row 2 (`screen.rs:598-607`), so nothing subsequently erases the newly wrapped `To`; the next emitted nonblank row is the absolute row-3 `Search`. The initial `ESC[2J` does not prevent the defect because the wrap scrap is created after the clear, during the synthesized repaint. Repeating the same valid construction on separate rows with suffixes `Wh` and `Es` deterministically produces the reported `To`, `Wh`, and `Es` fragments at column 1. This also explains why the fragments are exactly two cells when the row has accumulated two columns of width divergence.\n\nA second non-wrap kernel shows stale-prefix corruption directly:\n\n```text\n\\x1b[1;1H界界Today\\x1b[1;5HNEW\n```\n\nA real VT’s final row is `界界NEWay`: CUP column 5 overwrites `Tod`. Current `ScreenGrid` stores `界界Today` in seven scalar cells, so CUP column 5 overwrites scalar cells `day`; its authoritative state becomes `界界ToNEW`. A cold repaint therefore preserves the stale `To` prefix. Substitute source strings beginning `When…` or `Escape…` to obtain the `Wh`/`Es` family. Mapping those exact English prefixes to Claude’s captured frame is `[INFERENCE]` because the supplied child PTY byte capture is not in the repository, but the mechanism and byte reproducer are deterministic.\n\nThe production seam that exposes this state is `crates/spt-daemon/src/broker.rs:836-852`, `OutputLog::repaint_initial`: a cold attach with `from_seq == 0` returns `self.grid.render_repaint()` at pseudo-sequence `next_seq - 1`. `OutputLog::become_controller` at `broker.rs:1048-1072` sends that one synthesized repaint before subsequent raw live frames. Thus this is not terminal-emulator residue from an uncleared old screen: `render_repaint` explicitly switches the buffer, resets SGR, clears, and homes before painting, but paints the wrong authoritative cells.\n\nFix seam for hypothesis 1: `crates/spt-term/src/screen.rs`, centered on `Cell`, `GridState::put_char`, `render_repaint`, and every cell-edit/resize operation. Model terminal columns rather than Unicode scalars: a width-2 primary glyph must own its leading cell plus an explicit continuation cell; width-0 combining input must attach to the preceding grapheme rather than advance; overwriting either half of a wide glyph must clear the whole glyph; ICH/DCH/ECH/EL/ED, scrolling, and `resized_buffer` must preserve or deliberately clear continuation invariants; repaint must emit a wide primary once and emit no byte for its continuation cell. A mere `col += unicode_width(c)` without continuation cells is insufficient because absolute overwrites and edit operations would still leave torn glyph halves and phantom blanks.\n\nFocused regression: add a stateful width-aware repaint test beside `screen.rs:893+` that feeds the exact valid 3×10 frame above, obtains `render_repaint`, applies it to a tiny independent width-aware terminal oracle, and asserts: row 1 is exactly `界界ABCDTo`, row 2 is blank, row 3 begins `Search`, no printable byte wraps into row 2, and the final cursor matches the server state. The oracle must not reuse `ScreenGrid::put_char`, or the same bug will mask itself. Boundary cases should cover one wide glyph at the penultimate column, overwrite through either the primary or continuation cell, resize clipping a wide glyph, ICH/DCH across a continuation, and a combining mark that consumes zero columns. The exact `To` test fails current code and defends the observable screenshot contract.\n\n2. HIGH as a separate/compounding defect when enabled — rc’s client-side identity `StatusRow` is an unsafe out-of-band renderer, but current v0.38.x main intentionally disables it. `crates/spt/src/rc.rs:199-208` documents the known failure and sets `STATUS_ROW_ENABLED: bool = false`; `status_row_active` at `rc.rs:210-216` therefore returns false for controllers and viewers. `traceable-reqs.toml:1603-1606` records `REQ-RC-IDMARKER-DISABLE`: the one-shot absolute paint scrolls away and its DECSC/clear/SGR bytes splice into harness drawing. If the screenshot visibly contains this identity banner, then the running binary is older than this gate, locally modified, or otherwise not exercising current-main wiring `[INFERENCE]`. The banner is evidence that the hazardous path was active; it is not evidence against the ScreenGrid width defect.\n\nThe enabled overlay sequence is `StatusRow::assert_bytes` at `rc.rs:236-247` followed by `StatusRow::repaint_bytes` at `rc.rs:249-271`:\n\n```text\nESC [ 2 ; R r              DECSTBM reserve top row\nESC 7                      DECSC\nESC [ 1 ; 1 H\nESC [ 2 K\nESC [ 1 ; COL H\nESC [ 36 m  <identity>  ESC [ 0 m\nESC 8                      DECRC\n```\n\nThere are two cursor-state problems. First, DECSTBM is emitted before DECSC. DECSTBM changes the cursor position; therefore DECSC saves the post-margin cursor, not the child’s cursor that existed before the overlay. Second, DECSC/DECRC use the emulator’s one shared DEC saved-cursor slot, so an overlay between a child DECSC and its later DECRC overwrites the child’s saved state. The repository’s own terminal model demonstrates the relevant absolute semantics: CUP/HVP at `screen.rs:791-795` addresses absolute rows and columns, while DECSTBM at `screen.rs:808-817` changes margins and resets the cursor. A scroll margin is not a coordinate translation.\n\nThe exact interleaving seam is `rc.rs:2286-2303`: pump writes a complete child `AttachRecord::Output` chunk verbatim, then scans that same chunk, and if it saw alt-screen entry or DECSTBM reset, appends `status.assert_bytes()`. PTY/output-record chunk boundaries are not TUI-frame boundaries. A minimal cursor-corruption schedule is:\n\n```text\nchild chunk A:  \\x1b[?1049h\\x1b[4;3H\nrc injection:   \\x1b[2;6r\\x1b7\\x1b[1;1H\\x1b[2K...banner...\\x1b8\nchild chunk B:  To\n```\n\nWithout rc injection, chunk B begins at row 4, column 3. With the injection, DECSTBM resets the cursor before rc saves it; DECRC restores that reset position, so `To` lands at the left edge. This is deterministic out-of-band composition even though each individual `write_all` is not byte-torn.\n\nThe geometry contract is also unsound for an absolute-addressed TUI. `attach_viewport` at `rc.rs:1870-1882` reports PTY rows as physical rows minus one while preserving all columns. The physical terminal is only given scroll margins, not a vertical CUP translation. Claude may still issue `CUP 1;n` and touch physical row 1. Reserving a top row via DECSTBM therefore cannot transparently host a child that believes its own row 1 is the first row of an `(R-1)`-row screen. A bottom physical status row would align ordinary absolute child rows better, but child DECSTBM/alternate-screen transitions would still destroy the parent margin; raw pass-through cannot make two renderers safely share one VT state machine.\n\nResize makes the collision more likely. `attach_viewport` sends an initial resize at `rc.rs:1874-1882`. `pump` starts with `last_size = None` at `rc.rs:2190-2194`, so its first loop observes the same dimensions as a change and sends another resize; when status is enabled it immediately appends another `status.assert_bytes()` at `rc.rs:2210-2225`. The target forwards resize at `crates/spt-daemon/src/attach.rs:498-506`; the broker resizes the PTY and server grid at `broker.rs:4446-4466`; ConPTY or the child may then emit an asynchronous repaint. rc paints its banner before receiving that repaint, and ordinary repaint bytes do not necessarily contain one of `ReassertScanner`’s narrow triggers. The banner can be overwritten, scrolled, or left in history while the TUI and overlay disagree about the cursor.\n\nCurrent fix seam for hypothesis 2 is already the correct immediate one: keep `STATUS_ROW_ENABLED = false` and strengthen regression coverage at the real controller construction/geometry seam, not only the existing pure flag assertion at `rc.rs:3901-3908`. A permanent identity overlay must be composed by the one authoritative renderer on every frame, with an explicit physical layout, rather than injected by rc between raw child chunks. Existing `ScreenGrid` is the natural ownership seam, but it first needs correct wide/combining-cell semantics; merely re-enabling the old `StatusRow` after the grid exists would retain the cursor-slot, margin, and live-raw-output conflicts.\n\n3. MEDIUM — initial old-geometry repaint followed by resize/live repaint can amplify a cold-attach artifact. `OutputLog::repaint_initial` snapshots the grid for the attach, while rc sends resize immediately afterward. `broker.rs:1442-1447` updates `grid` geometry on controller resize, but that does not retract the already queued initial repaint. The initial synthesized frame and subsequent child/ConPTY redraw can therefore represent different geometries. The duplicate initial resize noted above increases redraw churn. This does not by itself explain the exact `To`/`Wh`/`Es` prefixes as strongly as the missing continuation cells, but it is a deterministic composition stressor. Focused regression: cold-attach at geometry A, resize to B before the initial writer drains, then assert one state-complete geometry-B repaint precedes raw B frames, or force baseline invalidation and repaint after resize.\n\n4. LOW on current main — missing DECSTBM replay was a real ScreenGrid defect but is already closed. ADR-0043 identifies it, and `screen.rs:610-629` now emits the tracked DECSTBM (or explicit `ESC[r`) before the final cursor CUP. Tests at `screen.rs:893-936` cover the stateful post-repaint scrolling contract. It should not be selected as the present root unless the running binary predates that change.\n\n5. LOW/refuted for the live screenshot — terminal-emulator and final-output ordering. Windows Terminal is expected to implement CUP, DECSTBM, DECSC/DECRC, and Unicode width; the deterministic wide-cell mismatch already exists in server state before bytes reach the emulator. Legacy conhost DECSC behavior can worsen the enabled overlay, but it is not required for either reproducer. rc writes child output and status injection sequentially on the pump thread (`rc.rs:2286-2303`), so the relevant interleaving is logical-frame/chunk interleaving, not concurrent partial writes to stdout. ADR-0043’s Output-before-Exit FIFO and `DisplayGuard` teardown (`rc.rs:858-898`, `1529-1590`) govern final exit/parting prose; they cannot cause stable corruption while Claude’s settings TUI is still active. `crates/spt-term/src/reader.rs:31-36,118-143` also auto-answers DSR with fixed `ESC[1;1R` while forwarding the query; a delayed physical CPR can duplicate the response, but that is a separate protocol issue and does not deterministically yield these two-character wrap scraps.","files":[{"path":"crates/spt-term/src/screen.rs","description":"Primary root. `Cell` has no continuation/grapheme representation (122-145); `put_char` advances one cell per scalar (330-349); erases/ICH/DCH operate on scalar cells (359-443); `render_repaint` emits those cells linearly and skips authoritative blank rows (577-629), allowing over-wide synthesized rows to wrap two-character scraps into an otherwise skipped row."},{"path":"crates/spt-term/Cargo.toml","description":"Confirms spt-term has `vte` parsing but no direct Unicode display-width/grapheme dependency; width semantics are not implemented elsewhere in this crate."},{"path":"crates/spt-daemon/src/broker.rs","description":"Exposure seam. `OutputLog` owns the authoritative `ScreenGrid`; `repaint_initial` (836-852) synthesizes it for cold `from_seq == 0` attaches, and `become_controller` (1048-1072) sends it as the initial frame.

The broker drain fans raw live bytes outward and independently advances one authoritative `ScreenGrid`. On a cold attach, the broker does not replay the retained raw ring; it synthesizes one full repaint from `ScreenGrid`, sends it as the initial Output frame, and then resumes unchanged raw live frames. rc decodes each Output and writes it verbatim to the physical terminal. This layering means corruption can be assigned precisely: (1) the child frame is valid under normal Unicode terminal widths; (2) the server grid currently maps Unicode scalars, not terminal columns, so its authoritative screen and cold repaint can already be wrong; (3) an enabled rc StatusRow is a second renderer mutating the same physical VT state outside both the child and server grid models; (4) Windows Terminal merely executes the resulting bytes; and (5) teardown/output-before-exit ordering acts only when the viewport ends. The exact screenshot-class `To`/`Wh`/`Es` scraps are best explained by layer 2: missing width-2 continuation cells insert two phantom logical blanks before an absolute right-hand segment, causing the synthesized row to become two physical cells overwide and wrap its last two characters into a blank row that repaint skips.

verdict\\n\\n1. HIGH — `ScreenGrid` has no wide-glyph continuation-cell model, and this is the strongest exact mechanism for the screenshot’s two-character left-margin scraps. `crates/spt-term/src/screen.rs:122-145` defines each cell as only `{ ch: char, pen: Pen }`. `GridState::put_char` at `screen.rs:330-349` advances exactly one grid column per Unicode scalar, regardless of terminal display width. The erase/edit paths at `screen.rs:359-443` likewise operate on those scalar cells. `crates/spt-term/Cargo.toml` depends on `vte` but not on a Unicode-width/grapheme implementation. `GridState::render_repaint` at `screen.rs:577-629` then emits the stored cells sequentially from an absolute `CUP row;1`. Consequently, a width-2 glyph occupies one authoritative grid cell but two cells in the real terminal; absolute cursor-addressed updates and synthesized repaint disagree by one column per wide glyph.\\n\\nDeterministic byte-level reproducer for the wrap/scrap class, using a 3-row × 10-column terminal:\\n\\n```text\\nChild frame fed to ScreenGrid:\\nESC [ 1 ; 1 H  界 界  ESC [ 1 ; 5 H  A B C D T o  ESC [ 3 ; 1 H  Search\\n\\nEscaped:\\n\\\\x1b[1;1H界界\\\\x1b[1;5HABCDTo\\\\x1b[3;1HSearch\\n\\nHex for each 界: e7 95 8c\\nCUP bytes: 1b 5b 31 3b 31 48 and 1b 5b 31 3b 35 48\\n```\\n\\nA width-aware VT renders the child frame correctly: the two `界` glyphs occupy columns 1–4 and `ABCDTo` occupies columns 5–10; row 2 stays blank and `Search` begins on row 3. Current `ScreenGrid` instead stores the two glyphs in logical cells 1–2, leaves logical cells 3–4 blank, and stores `ABCDTo` in cells 5–10. The cold-attach repaint therefore emits the visible row as:\\n\\n```text\\n界界··ABCDTo\\n```\\n\\nwhere `··` are the two erroneous stored blank cells. That byte string has physical display width 12. On a 10-column terminal, `To` wraps to row 2, columns 1–2. `render_repaint` skips the authoritative grid’s default-blank row 2 (`screen.rs:598-607`), so nothing subsequently erases the newly wrapped `To`; the next emitted nonblank row is the absolute row-3 `Search`. The initial `ESC[2J` does not prevent the defect because the wrap scrap is created after the clear, during the synthesized repaint. Repeating the same valid construction on separate rows with suffixes `Wh` and `Es` deterministically produces the reported `To`, `Wh`, and `Es` fragments at column 1. This also explains why the fragments are exactly two cells when the row has accumulated two columns of width divergence.\\n\\nA second non-wrap kernel shows stale-prefix corruption directly:\\n\\n```text\\n\\\\x1b[1;1H界界Today\\\\x1b[1;5HNEW\\n```\\n\\nA real VT’s final row is `界界NEWay`: CUP column 5 overwrites `Tod`. Current `ScreenGrid` stores `界界Today` in seven scalar cells, so CUP column 5 overwrites scalar cells `day`; its authoritative state becomes `界界ToNEW`. A cold repaint therefore preserves the stale `To` prefix. Substitute source strings beginning `When…` or `Escape…` to obtain the `Wh`/`Es` family. Mapping those exact English prefixes to Claude’s captured frame is `[INFERENCE]` because the supplied child PTY byte capture is not in the repository, but the mechanism and byte reproducer are deterministic.\\n\\nThe production seam that exposes this state is `crates/spt-daemon/src/broker.rs:836-852`, `OutputLog::repaint_initial`: a cold attach with `from_seq == 0` returns `self.grid.render_repaint()` at pseudo-sequence `next_seq - 1`. `OutputLog::become_controller` at `broker.rs:1048-1072` sends that one synthesized repaint before subsequent raw live frames. Thus this is not terminal-emulator residue from an uncleared old screen: `render_repaint` explicitly switches the buffer, resets SGR, clears, and homes before painting, but paints the wrong authoritative cells.\\n\\nFix seam for hypothesis 1: `crates/spt-term/src/screen.rs`, centered on `Cell`, `GridState::put_char`, `render_repaint`, and every cell-edit/resize operation. Model terminal columns rather than Unicode scalars: a width-2 primary glyph must own its leading cell plus an explicit continuation cell; width-0 combining input must attach to the preceding grapheme rather than advance; overwriting either half of a wide glyph must clear the whole glyph; ICH/DCH/ECH/EL/ED, scrolling, and `resized_buffer` must preserve or deliberately clear continuation invariants; repaint must emit a wide primary once and emit no byte for its continuation cell. A mere `col += unicode_width(c)` without continuation cells is insufficient because absolute overwrites and edit operations would still leave torn glyph halves and phantom blanks.\\n\\nFocused regression: add a stateful width-aware repaint test beside `screen.rs:893+` that feeds the exact valid 3×10 frame above, obtains `render_repaint`, applies it to a tiny independent width-aware terminal oracle, and asserts: row 1 is exactly `界界ABCDTo`, row 2 is blank, row 3 begins `Search`, no printable byte wraps into row 2, and the final cursor matches the server state. The oracle must not reuse `ScreenGrid::put_char`, or the same bug will mask itself. Boundary cases should cover one wide glyph at the penultimate column, overwrite through either the primary or continuation cell, resize clipping a wide glyph, ICH/DCH across a continuation, and a combining mark that consumes zero columns. The exact `To` test fails current code and defends the observable screenshot contract.\\n\\n2. HIGH as a separate/compounding defect when enabled — rc’s client-side identity `StatusRow` is an unsafe out-of-band renderer, but current v0.38.x main intentionally disables it. `crates/spt/src/rc.rs:199-208` documents the known failure and sets `STATUS_ROW_ENABLED: bool = false`; `status_row_active` at `rc.rs:210-216` therefore returns false for controllers and viewers. `traceable-reqs.toml:1603-1606` records `REQ-RC-IDMARKER-DISABLE`: the one-shot absolute paint scrolls away and its DECSC/clear/SGR bytes splice into harness drawing. If the screenshot visibly contains this identity banner, then the running binary is older than this gate, locally modified, or otherwise not exercising current-main wiring `[INFERENCE]`. The banner is evidence that the hazardous path was active; it is not evidence against the ScreenGrid width defect.\\n\\nThe enabled overlay sequence is `StatusRow::assert_bytes` at `rc.rs:236-247` followed by `StatusRow::repaint_bytes` at `rc.rs:249-271`:\\n\\n```text\\nESC [ 2 ; R r              DECSTBM reserve top row\\nESC 7                      DECSC\\nESC [ 1 ; 1 H\\nESC [ 2 K\\nESC [ 1 ; COL H\\nESC [ 36 m  <identity>  ESC [ 0 m\\nESC 8                      DECRC\\n```\\n\\nThere are two cursor-state problems. First, DECSTBM is emitted before DECSC. DECSTBM changes the cursor position; therefore DECSC saves the post-margin cursor, not the child’s cursor that existed before the overlay. Second, DECSC/DECRC use the emulator’s one shared DEC saved-cursor slot, so an overlay between a child DECSC and its later DECRC overwrites the child’s saved state. The repository’s own terminal model demonstrates the relevant absolute semantics: CUP/HVP at `screen.rs:791-795` addresses absolute rows and columns, while DECSTBM at `screen.rs:808-817` changes margins and resets the cursor. A scroll margin is not a coordinate translation.\\n\\nThe exact interleaving seam is `rc.rs:2286-2303`: pump writes a complete child `AttachRecord::Output` chunk verbatim, then scans that same chunk, and if it saw alt-screen entry or DECSTBM reset, appends `status.assert_bytes()`. PTY/output-record chunk boundaries are not TUI-frame boundaries. A minimal cursor-corruption schedule is:\\n\\n```text\\nchild chunk A:  \\\\x1b[?1049h\\\\x1b[4;3H\\nrc injection:   \\\\x1b[2;6r\\\\x1b7\\\\x1b[1;1H\\\\x1b[2K...banner...\\\\x1b8\\nchild chunk B:  To\\n```\\n\\nWithout rc injection, chunk B begins at row 4, column 3. With the injection, DECSTBM resets the cursor before rc saves it; DECRC restores that reset position, so `To` lands at the left edge. This is deterministic out-of-band composition even though each individual `write_all` is not byte-torn.\\n\\nThe geometry contract is also unsound for an absolute-addressed TUI. `attach_viewport` at `rc.rs:1870-1882` reports PTY rows as physical rows minus one while preserving all columns. The physical terminal is only given scroll margins, not a vertical CUP translation. Claude may still issue `CUP 1;n` and touch physical row 1. Reserving a top row via DECSTBM therefore cannot transparently host a child that believes its own row 1 is the first row of an `(R-1)`-row screen. A bottom physical status row would align ordinary absolute child rows better, but child DECSTBM/alternate-screen transitions would still destroy the parent margin; raw pass-through cannot make two renderers safely share one VT state machine.\\n\\nResize makes the collision more likely. `attach_viewport` sends an initial resize at `rc.rs:1874-1882`. `pump` starts with `last_size = None` at `rc.rs:2190-2194`, so its first loop observes the same dimensions as a change and sends another resize; when status is enabled it immediately appends another `status.assert_bytes()` at `rc.rs:2210-2225`. The target forwards resize at `crates/spt-daemon/src/attach.rs:498-506`; the broker resizes the PTY and server grid at `broker.rs:4446-4466`; ConPTY or the child may then emit an asynchronous repaint. rc paints its banner before receiving that repaint, and ordinary repaint bytes do not necessarily contain one of `ReassertScanner`’s narrow triggers. The banner can be overwritten, scrolled, or left in history while the TUI and overlay disagree about the cursor.\\n\\nCurrent fix seam for hypothesis 2 is already the correct immediate one: keep `STATUS_ROW_ENABLED = false` and strengthen regression coverage at the real controller construction/geometry seam, not only the existing pure flag assertion at `rc.rs:3901-3908`. A permanent identity overlay must be composed by the one authoritative renderer on every frame, with an explicit physical layout, rather than injected by rc between raw child chunks. Existing `ScreenGrid` is the natural ownership seam, but it first needs correct wide/combining-cell semantics; merely re-enabling the old `StatusRow` after the grid exists would retain the cursor-slot, margin, and live-raw-output conflicts.\\n\\n3. MEDIUM — initial old-geometry repaint followed by resize/live repaint can amplify a cold-attach artifact. `OutputLog::repaint_initial` snapshots the grid for the attach, while rc sends resize immediately afterward. `broker.rs:1442-1447` updates `grid` geometry on controller resize, but that does not retract the already queued initial repaint. The initial synthesized frame and subsequent child/ConPTY redraw can therefore represent different geometries. The duplicate initial resize noted above increases redraw churn. This does not by itself explain the exact `To`/`Wh`/`Es` prefixes as strongly as the missing continuation cells, but it is a deterministic composition stressor. Focused regression: cold-attach at geometry A, resize to B before the initial writer drains, then assert one state-complete geometry-B repaint precedes raw B frames, or force baseline invalidation and repaint after resize.\\n\\n4. LOW on current main — missing DECSTBM replay was a real ScreenGrid defect but is already closed. ADR-0043 identifies it, and `screen.rs:610-629` now emits the tracked DECSTBM (or explicit `ESC[r`) before the final cursor CUP. Tests at `screen.rs:893-936` cover the stateful post-repaint scrolling contract. It should not be selected as the present root unless the running binary predates that change.\\n\\n5. LOW/refuted for the live screenshot — terminal-emulator and final-output ordering. Windows Terminal is expected to implement CUP, DECSTBM, DECSC/DECRC, and Unicode width; the deterministic wide-cell mismatch already exists in server state before bytes reach the emulator. Legacy conhost DECSC behavior can worsen the enabled overlay, but it is not required for either reproducer. rc writes child output and status injection sequentially on the pump thread (`rc.rs:2286-2303`), so the relevant interleaving is logical-frame/chunk interleaving, not concurrent partial writes to stdout. ADR-0043’s Output-before-Exit FIFO and `DisplayGuard` teardown (`rc.rs:858-898`, `1529-1590`) govern final exit/parting prose; they cannot cause stable corruption while Claude’s settings TUI is still active. `crates/spt-term/src/reader.rs:31-36,118-143` also auto-answers DSR with fixed `ESC[1;1R` while forwarding the query; a delayed physical CPR can duplicate the response, but that is a separate protocol issue and does not deterministically yield these two-character wrap scraps.\",\"files\":[{\"path\":\"crates/spt-term/src/screen.rs\",\"description\":\"Primary root. `Cell` has no continuation/grapheme representation (122-145); `put_char` advances one cell per scalar (330-349); erases/ICH/DCH operate on scalar cells (359-443); `render_repaint` emits those cells linearly and skips authoritative blank rows (577-629), allowing over-wide synthesized rows to wrap two-character scraps into an otherwise skipped row.\"},{\"path\":\"crates/spt-term/Cargo.toml\",\"description\":\"Confirms spt-term has `vte` parsing but no direct Unicode display-width/grapheme dependency; width semantics are not implemented elsewhere in this crate.\"},{\"path\":\"crates/spt-daemon/src/broker.rs\",\"description\":\"Exposure seam. `OutputLog` owns the authoritative `ScreenGrid`; `repaint_initial` (836-852) synthesizes it for cold `from_seq == 0` attaches, and `become_controller` (1048-1072) sends it as the initial frame.

Current `ScreenGrid` instead stores the two glyphs in logical cells 1–2, leaves logical cells 3–4 blank, and stores `ABCDTo` in cells 5–10. The cold-attach repaint therefore emits the visible row as:\n\n```text\n界界··ABCDTo\n```\n\nwhere `··` are the two erroneous stored blank cells. That byte string has physical display width 12. On a 10-column terminal, `To` wraps to row 2, columns 1–2. `render_repaint` skips the authoritative grid’s default-blank row 2 (`screen.rs:598-607`), so nothing subsequently erases the newly wrapped `To`; the next emitted nonblank row is the absolute row-3 `Search`. The initial `ESC[2J` does not prevent the defect because the wrap scrap is created after the clear, during the synthesized repaint. Repeating the same valid construction on separate rows with suffixes `Wh` and `Es` deterministically produces the reported `To`, `Wh`, and `Es` fragments at column 1. This also explains why the fragments are exactly two cells when the row has accumulated two columns of width divergence.\n\nA second non-wrap kernel shows stale-prefix corruption directly:\n\n```text\n\\x1b[1;1H界界Today\\x1b[1;5HNEW\n```\n\nA real VT’s final row is `界界NEWay`: CUP column 5 overwrites `Tod`. Current `ScreenGrid` stores `界界Today` in seven scalar cells, so CUP column 5 overwrites scalar cells `day`; its authoritative state becomes `界界ToNEW`. A cold repaint therefore preserves the stale `To` prefix. Substitute source strings beginning `When…` or `Escape…` to obtain the `Wh`/`Es` family. Mapping those exact English prefixes to Claude’s captured frame is `[INFERENCE]` because the supplied child PTY byte capture is not in the repository, but the mechanism and byte reproducer are deterministic.\n\nThe production seam that exposes this state is `crates/spt-daemon/src/broker.rs:836-852`, `OutputLog::repaint_initial`: a cold attach with `from_seq == 0` returns `self.grid.render_repaint()` at pseudo-sequence `next_seq - 1`. `OutputLog::become_controller` at `broker.rs:1048-1072` sends that one synthesized repaint before subsequent raw live frames.

Boundary cases should cover one wide glyph at the penultimate column, overwrite through either the primary or continuation cell, resize clipping a wide glyph, ICH/DCH across a continuation, and a combining mark that consumes zero columns. The exact `To` test fails current code and defends the observable screenshot contract.\n\n2. HIGH as a separate/compounding defect when enabled — rc’s client-side identity `StatusRow` is an unsafe out-of-band renderer, but current v0.38.x main intentionally disables it. `crates/spt/src/rc.rs:199-208` documents the known failure and sets `STATUS_ROW_ENABLED: bool = false`; `status_row_active` at `rc.rs:210-216` therefore returns false for controllers and viewers. `traceable-reqs.toml:1603-1606` records `REQ-RC-IDMARKER-DISABLE`: the one-shot absolute paint scrolls away and its DECSC/clear/SGR bytes splice into harness drawing. If the screenshot visibly contains this identity banner, then the running binary is older than this gate, locally modified, or otherwise not exercising current-main wiring `[INFERENCE]`. The banner is evidence that the hazardous path was active; it is not evidence against the ScreenGrid width defect.\n\nThe enabled overlay sequence is `StatusRow::assert_bytes` at `rc.rs:236-247` followed by `StatusRow::repaint_bytes` at `rc.rs:249-271`:\n\n```text\nESC [ 2 ; R r              DECSTBM reserve top row\nESC 7                      DECSC\nESC [ 1 ; 1 H\nESC [ 2 K\nESC [ 1 ; COL H\nESC [ 36 m  <identity>  ESC [ 0 m\nESC 8                      DECRC\n```\n\nThere are two cursor-state problems. First, DECSTBM is emitted before DECSC. DECSTBM changes the cursor position; therefore DECSC saves the post-margin cursor, not the child’s cursor that existed before the overlay. Second, DECSC/DECRC use the emulator’s one shared DEC saved-cursor slot, so an overlay between a child DECSC and its later DECRC overwrites the child’s saved state. The repository’s own terminal model demonstrates the relevant absolute semantics: CUP/HVP at `screen.rs:791-795` addresses absolute rows and columns, while DECSTBM at `screen.rs:808-817` changes margins and resets the cursor. A scroll margin is not a coordinate translation.\n\nThe exact interleaving seam is `rc.rs:2286-2303`: pump writes a complete child `AttachRecord::Output` chunk verbatim, then scans that same chunk, and if it saw alt-screen entry or DECSTBM reset, appends `status.assert_bytes()`. PTY/output-record chunk boundaries are not TUI-frame boundaries. A minimal cursor-corruption schedule is:\n\n```text\nchild chunk A:  \\x1b[?1049h\\x1b[4;3H\nrc injection:   \\x1b[2;6r\\x1b7\\x1b[1;1H\\x1b[2K...banner...\\x1b8\nchild chunk B:  To\n```\n\nWithout rc injection, chunk B begins at row 4, column 3. With the injection, DECSTBM resets the cursor before rc saves it; DECRC restores that reset position, so `To` lands at the left edge. This is deterministic out-of-band composition even though each individual `write_all` is not byte-torn.\n\nThe geometry contract is also unsound for an absolute-addressed TUI. `attach_viewport` at `rc.rs:1870-1882` reports PTY rows as physical rows minus one while preserving all columns. The physical terminal is only given scroll margins, not a vertical CUP translation. Claude may still issue `CUP 1;n` and touch physical row 1. Reserving a top row via DECSTBM therefore cannot transparently host a child that believes its own row 1 is the first row of an `(R-1)`-row screen. A bottom physical status row would align ordinary absolute child rows better, but child DECSTBM/alternate-screen transitions would still destroy the parent margin; raw pass-through cannot make two renderers safely share one VT state machine.\n\nResize makes the collision more likely. `attach_viewport` sends an initial resize at `rc.rs:1874-1882`. `pump` starts with `last_size = None` at `rc.rs:2190-2194`, so its first loop observes the same dimensions as a change and sends another resize; when status is enabled it immediately appends another `status.assert_bytes()` at `rc.rs:2210-2225`. The target forwards resize at `crates/spt-daemon/src/attach.rs:498-506`; the broker resizes the PTY and server grid at `broker.rs:4446-4466`; ConPTY or the child may then emit an asynchronous repaint. rc paints its banner before receiving that repaint, and ordinary repaint bytes do not necessarily contain one of `ReassertScanner`’s narrow triggers. The banner can be overwritten, scrolled, or left in history while the TUI and overlay disagree about the cursor.\n\nCurrent fix seam for hypothesis 2 is already the correct immediate one: keep `STATUS_ROW_ENABLED = false` and strengthen regression coverage at the real controller construction/geometry seam, not only the existing pure flag assertion at `rc.rs:3901-3908`. A permanent identity overlay must be composed by the one authoritative renderer on every frame, with an explicit physical layout, rather than injected by rc between raw child chunks. Existing `ScreenGrid` is the natural ownership seam, but it first needs correct wide/combining-cell semantics; merely re-enabling the old `StatusRow` after the grid exists would retain the cursor-slot, margin, and live-raw-output conflicts.\n\n3. MEDIUM — initial old-geometry repaint followed by resize/live repaint can amplify a cold-attach artifact. `OutputLog::repaint_initial` snapshots the grid for the attach, while rc sends resize immediately afterward. `broker.rs:1442-1447` updates `grid` geometry on controller resize, but that does not retract the already queued initial repaint. The initial synthesized frame and subsequent child/ConPTY redraw can therefore represent different geometries. The duplicate initial resize noted above increases redraw churn. This does not by itself explain the exact `To`/`Wh`/`Es` prefixes as strongly as the missing continuation cells, but it is a deterministic composition stressor. Focused regression: cold-attach at geometry A, resize to B before the initial writer drains, then assert one state-complete geometry-B repaint precedes raw B frames, or force baseline invalidation and repaint after resize.\n\n4. LOW on current main — missing DECSTBM replay was a real ScreenGrid defect but is already closed. ADR-0043 identifies it, and `screen.rs:610-629` now emits the tracked DECSTBM (or explicit `ESC[r`) before the final cursor CUP. Tests at `screen.rs:893-936` cover the stateful post-repaint scrolling contract. It should not be selected as the present root unless the running binary predates that change.\n\n5. LOW/refuted for the live screenshot — terminal-emulator and final-output ordering. Windows Terminal is expected to implement CUP, DECSTBM, DECSC/DECRC, and Unicode width; the deterministic wide-cell mismatch already exists in server state before bytes reach the emulator. Legacy conhost DECSC behavior can worsen the enabled overlay, but it is not required for either reproducer. rc writes child output and status injection sequentially on the pump thread (`rc.rs:2286-2303`), so the relevant interleaving is logical-frame/chunk interleaving, not concurrent partial writes to stdout. ADR-0043’s Output-before-Exit FIFO and `DisplayGuard` teardown (`rc.rs:858-898`, `1529-1590`) govern final exit/parting prose; they cannot cause stable corruption while Claude’s settings TUI is still active. `crates/spt-term/src/reader.rs:31-36,118-143` also auto-answers DSR with fixed `ESC[1;1R` while forwarding the query; a delayed physical CPR can duplicate the response, but that is a separate protocol issue and does not deterministically yield these two-character wrap scraps.","files":[{"path":"crates/spt-term/src/screen.rs","description":"Primary root. `Cell` has no continuation/grapheme representation (122-145); `put_char` advances one cell per scalar (330-349); erases/ICH/DCH operate on scalar cells (359-443); `render_repaint` emits those cells linearly and skips authoritative blank rows (577-629), allowing over-wide synthesized rows to wrap two-character scraps into an otherwise skipped row."},{"path":"crates/spt-term/Cargo.toml","description":"Confirms spt-term has `vte` parsing but no direct Unicode display-width/grapheme dependency; width semantics are not implemented elsewhere in this crate."},{"path":"crates/spt-daemon/src/broker.rs","description":"Exposure seam. `OutputLog` owns the authoritative `ScreenGrid`; `repaint_initial` (836-852) synthesizes it for cold `from_seq == 0` attaches, and `become_controller` (1048-1072) sends it as the initial frame.

This layering means corruption can be assigned precisely: (1) the child frame is valid under normal Unicode terminal widths; (2) the server grid currently maps Unicode scalars, not terminal columns, so its authoritative screen and cold repaint can already be wrong; (3) an enabled rc StatusRow is a second renderer mutating the same physical VT state outside both the child and server grid models; (4) Windows Terminal merely executes the resulting bytes; and (5) teardown/output-before-exit ordering acts only when the viewport ends. The exact screenshot-class `To`/`Wh`/`Es` scraps are best explained by layer 2: missing width-2 continuation cells insert two phantom logical blanks before an absolute right-hand segment, causing the synthesized row to become two physical cells overwide and wrap its last two characters into a blank row that repaint skips.

Erase and character-edit operations at lines 359-443 operate on the same scalar cells. `render_repaint` at lines 577-629 emits stored cells sequentially from absolute `CUP row;1` and skips authoritative rows that it believes are blank. `crates/spt-term/Cargo.toml` has `vte` but no direct Unicode-width/grapheme dependency.\n\nThis yields a deterministic byte-level reproduction of the screenshot’s two-character scraps. Use a 3-row × 10-column width-aware terminal and feed the server grid:\n\n```text\n\\x1b[1;1H界界ABCDEFTo\\x1b[2;1H\\x1b[2K\\x1b[3;1HSearch\n```\n\nEach `界` is UTF-8 `e7 95 8c` and occupies two terminal columns. On the real child terminal, `界界ABCDEFTo` consumes 12 display cells, so `To` wraps to row 2; the following `CUP 2;1` + `EL 2` clears that legitimate wrap; `Search` is then painted on row 3. Correct final state: row 1 contains the intended first ten display cells, row 2 is blank, and row 3 begins `Search`.\n\nCurrent `ScreenGrid` undercounts the two wide glyphs by two columns, stores all ten Unicode scalars `界界ABCDEFTo` in its ten scalar cells on row 1, and regards row 2 as blank even before EL. Its synthesized repaint clears the physical terminal, emits row 1 as all ten scalars—physical width 12—and thereby re-creates a false `To` wrap at row 2, columns 1–2. Because the authoritative grid thinks row 2 is blank, `render_repaint` skips it at lines 598-607; nothing erases the newly created `To` before it emits absolute row-3 `Search`. Replacing the final suffix with `Wh` or `Es` produces the reported scrap family. This is a differential failure: real terminal after the original child bytes has a blank row above Search; a fresh terminal after the synthesized repaint has `To` above Search.\n\nAn equally valid absolute-addressing kernel is:\n\n```text\n\\x1b[1;1H界界\\x1b[1;5HABCDTo\\x1b[3;1HSearch\n```\n\nA correct VT places the two wide glyphs in columns 1–4 and `ABCDTo` in 5–10. The scalar grid stores the glyphs in cells 1–2, phantom blanks in 3–4, and `ABCDTo` in 5–10; repaint emits `界界··ABCDTo`, physical width 12, wrapping `To` into the modeled-blank/skipped second row. The exact mapping of `To`/`Wh`/`Es` to Claude’s uncaptured row strings is `[INFERENCE]`, but the two-cell wrap mechanism and failing byte sequence are deterministic.\n\nThe production exposure seam is `crates/spt-daemon/src/broker.rs:836-852`, `OutputLog::repaint_initial`: for a cold `from_seq == 0` attach it returns `self.grid.render_repaint()` at pseudo-sequence `next_seq - 1`. `OutputLog::become_controller` at lines 1048-1072 sends that synthesized repaint as the initial Output before subsequent unchanged raw live frames. Thus the error exists before Windows Terminal receives the bytes. `render_repaint` does issue buffer selection, SGR reset, `ESC[2J`, and home before painting; the scraps are created after that clear by the incorrect over-wide repaint, not inherited from an uncleared old client screen.\n\nFIX SEAM for rank 1: `screen.rs` `Cell`, `put_char`, `render_repaint`, erases, ICH/DCH/ECH, scrolling, and `resized_buffer`. Represent terminal columns, including an explicit continuation cell for a width-2 primary glyph; attach width-0 combining marks to the preceding grapheme; clear an entire glyph when either half is overwritten; preserve/repair continuation invariants across editing and resize; emit a wide primary exactly once and emit no printable byte for its continuation. Merely changing `col += width` without continuation cells is insufficient because absolute overwrite, erasure, insertion/deletion, and resize would retain torn glyph halves or phantom gaps.\n\nFOCUSED REGRESSION: add a stateful differential test beside the existing `screen.rs:893+` repaint tests. Feed the exact sequential 3×10 trace above, synthesize the repaint, apply it to an independent tiny width-aware VT oracle, and assert row 2 is blank and row 3 begins `Search`; current code deterministically leaves `To` at row 2, columns 1–2. The oracle must not reuse `ScreenGrid::put_char`, or the defect will self-mask. Add boundary assertions for overwrite through either half of a wide glyph, a wide glyph at the penultimate column, ICH/DCH/ECH/EL across a continuation, clipping on resize, and a zero-width combining mark.\n\nRANK 2 — HIGH as a compounding path when enabled, but disabled on current main: rc’s `StatusRow` is a second renderer injecting terminal state outside both the child TUI and server grid. `crates/spt/src/rc.rs:199-208` sets `STATUS_ROW_ENABLED = false`; `status_row_active` at 210-216 therefore constructs no row for controllers or viewers. `traceable-reqs.toml:1603-1606` explicitly records why: the one-shot absolute banner scrolls away and its DECSC/clear/SGR injection splices into in-flight harness drawing. A screenshot that visibly contains the identity banner therefore came from an older binary, a locally re-enabled build, or another non-current-main configuration `[INFERENCE]`.\n\nWhen enabled, `StatusRow::assert_bytes` at `rc.rs:236-247` emits DECSTBM before `StatusRow::repaint_bytes` at 249-271 saves the cursor:\n\n```text\nESC[2;Rr ESC7 ESC[1;1H ESC[2K ESC[1;COLH ESC[36m <identity> ESC[0m ESC8\n```\n\nDECSTBM changes the cursor before DECSC, so rc saves/restores the post-margin cursor rather than the child’s pre-overlay cursor. DECSC/DECRC also share the emulator’s single DEC saved-cursor slot with the child. The repository’s terminal model shows the underlying mismatch: CUP/HVP is absolute at `screen.rs:791-795`; DECSTBM changes margins and resets the cursor at 808-817. A scroll region is not a vertical coordinate translation.\n\nThe output splice is exact at `rc.rs:2286-2303`: rc writes a complete child Output chunk verbatim, scans that chunk, then appends the banner assertion if it saw alt-screen enter or DECSTBM reset. PTY chunks are not TUI-frame boundaries.

With it, DECSTBM resets the cursor before rc saves it, and chunk B begins at the restored margin-home/left position. This is logical-frame interleaving even though individual `write_all` calls are sequential and byte-complete.\n\nThe geometry is also invalid for an absolute-addressed child. `attach_viewport` at `rc.rs:1870-1882` gives the PTY `physical_rows - 1` but does not translate the child’s CUP coordinates; Claude’s `CUP 1;n` still addresses physical row 1 and can overwrite the supposed reserved row. The initial resize is sent at 1874-1882; `pump` starts with `last_size = None` at 2190-2194 and sends the same size again on its first loop, immediately adding another status assertion at 2210-2225. Resize is forwarded at `crates/spt-daemon/src/attach.rs:498-506` and applied to the PTY/grid at `broker.rs:4446-4466`, so ConPTY/Claude redraw can race semantically with those one-shot paints.\n\nFIX SEAM for rank 2: the immediate production fix is already correct—keep `STATUS_ROW_ENABLED = false`, ensure the controller uses full terminal dimensions, and add a real controller-path assertion that no status bytes or row subtraction occur. A permanent identity UI must be composed by one authoritative renderer on every frame with explicit physical layout; it must not be restored by re-enabling the rc raw-byte injector. The existing `ScreenGrid` is the natural future ownership seam, after its Unicode cell model is fixed.\n\nRANK 3 — MEDIUM: cold repaint at old geometry followed by controller resize/live child repaint can amplify the corruption. The cold repaint can already be queued when rc sends the initial size. `broker.rs:1442-1447` changes grid geometry on resize but cannot retract an already queued repaint; the duplicate initial resize increases redraw churn. This is a composition stressor, not as exact an explanation of `To`/`Wh`/`Es` as rank 1.\n\nRANK 4 — LOW/currently closed: ScreenGrid previously omitted DECSTBM from cold repaint. ADR-0043 identifies it, but `screen.rs:610-629` now emits the tracked region or explicit `ESC[r` before final cursor placement; tests at 893-936 cover post-repaint scroll equivalence.\n\nRANK 5 — LOW/refuted for the active settings screenshot: Windows Terminal is expected to implement Unicode width and the cited VT controls; the malformed authoritative repaint exists server-side first. Legacy conhost DECSC quirks can worsen rank 2 but are not needed. Final Output-before-Exit ordering and `DisplayGuard` teardown (`rc.rs:858-898`, 1529-1590) act when the viewport ends, not while the settings TUI is active. The DSR auto-answer in `crates/spt-term/src/reader.rs:31-36,118-143` can produce a fixed CPR plus a delayed physical CPR, but it is a separate protocol concern and does not deterministically produce two-character wrap scraps.","files":[{"path":"crates/spt-term/src/screen.rs","description":"Primary defect and fix seam.

On the real child terminal, `界界ABCDEFTo` consumes 12 display cells, so `To` wraps to row 2; the following `CUP 2;1` + `EL 2` clears that legitimate wrap; `Search` is then painted on row 3. Correct final state: row 1 contains the intended first ten display cells, row 2 is blank, and row 3 begins `Search`.\\n\\nCurrent `ScreenGrid` undercounts the two wide glyphs by two columns, stores all ten Unicode scalars `界界ABCDEFTo` in its ten scalar cells on row 1, and regards row 2 as blank even before EL. Its synthesized repaint clears the physical terminal, emits row 1 as all ten scalars—physical width 12—and thereby re-creates a false `To` wrap at row 2, columns 1–2. Because the authoritative grid thinks row 2 is blank, `render_repaint` skips it at lines 598-607; nothing erases the newly created `To` before it emits absolute row-3 `Search`. Replacing the final suffix with `Wh` or `Es` produces the reported scrap family. This is a differential failure: real terminal after the original child bytes has a blank row above Search; a fresh terminal after the synthesized repaint has `To` above Search.\\n\\nAn equally valid absolute-addressing kernel is:\\n\\n```text\\n\\\\x1b[1;1H界界\\\\x1b[1;5HABCDTo\\\\x1b[3;1HSearch\\n```\\n\\nA correct VT places the two wide glyphs in columns 1–4 and `ABCDTo` in 5–10. The scalar grid stores the glyphs in cells 1–2, phantom blanks in 3–4, and `ABCDTo` in 5–10; repaint emits `界界··ABCDTo`, physical width 12, wrapping `To` into the modeled-blank/skipped second row. The exact mapping of `To`/`Wh`/`Es` to Claude’s uncaptured row strings is `[INFERENCE]`, but the two-cell wrap mechanism and failing byte sequence are deterministic.\\n\\nThe production exposure seam is `crates/spt-daemon/src/broker.rs:836-852`, `OutputLog::repaint_initial`: for a cold `from_seq == 0` attach it returns `self.grid.render_repaint()` at pseudo-sequence `next_seq - 1`. `OutputLog::become_controller` at lines 1048-1072 sends that synthesized repaint as the initial Output before subsequent unchanged raw live frames. Thus the error exists before Windows Terminal receives the bytes. `render_repaint` does issue buffer selection, SGR reset, `ESC[2J`, and home before painting; the scraps are created after that clear by the incorrect over-wide repaint, not inherited from an uncleared old client screen.\\n\\nFIX SEAM for rank 1: `screen.rs` `Cell`, `put_char`, `render_repaint`, erases, ICH/DCH/ECH, scrolling, and `resized_buffer`. Represent terminal columns, including an explicit continuation cell for a width-2 primary glyph; attach width-0 combining marks to the preceding grapheme; clear an entire glyph when either half is overwritten; preserve/repair continuation invariants across editing and resize; emit a wide primary exactly once and emit no printable byte for its continuation. Merely changing `col += width` without continuation cells is insufficient because absolute overwrite, erasure, insertion/deletion, and resize would retain torn glyph halves or phantom gaps.\\n\\nFOCUSED REGRESSION: add a stateful differential test beside the existing `screen.rs:893+` repaint tests. Feed the exact sequential 3×10 trace above, synthesize the repaint, apply it to an independent tiny width-aware VT oracle, and assert row 2 is blank and row 3 begins `Search`; current code deterministically leaves `To` at row 2, columns 1–2. The oracle must not reuse `ScreenGrid::put_char`, or the defect will self-mask. Add boundary assertions for overwrite through either half of a wide glyph, a wide glyph at the penultimate column, ICH/DCH/ECH/EL across a continuation, clipping on resize, and a zero-width combining mark.\\n\\nRANK 2 — HIGH as a compounding path when enabled, but disabled on current main: rc’s `StatusRow` is a second renderer injecting terminal state outside both the child TUI and server grid. `crates/spt/src/rc.rs:199-208` sets `STATUS_ROW_ENABLED = false`; `status_row_active` at 210-216 therefore constructs no row for controllers or viewers. `traceable-reqs.toml:1603-1606` explicitly records why: the one-shot absolute banner scrolls away and its DECSC/clear/SGR injection splices into in-flight harness drawing. A screenshot that visibly contains the identity banner therefore came from an older binary, a locally re-enabled build, or another non-current-main configuration `[INFERENCE]`.\\n\\nWhen enabled, `StatusRow::assert_bytes` at `rc.rs:236-247` emits DECSTBM before `StatusRow::repaint_bytes` at 249-271 saves the cursor:\\n\\n```text\\nESC[2;Rr ESC7 ESC[1;1H ESC[2K ESC[1;COLH ESC[36m <identity> ESC[0m ESC8\\n```\\n\\nDECSTBM changes the cursor before DECSC, so rc saves/restores the post-margin cursor rather than the child’s pre-overlay cursor. DECSC/DECRC also share the emulator’s single DEC saved-cursor slot with the child. The repository’s terminal model shows the underlying mismatch: CUP/HVP is absolute at `screen.rs:791-795`; DECSTBM changes margins and resets the cursor at 808-817. A scroll region is not a vertical coordinate translation.\\n\\nThe output splice is exact at `rc.rs:2286-2303`: rc writes a complete child Output chunk verbatim, scans that chunk, then appends the banner assertion if it saw alt-screen enter or DECSTBM reset. PTY chunks are not TUI-frame boundaries. Minimal schedule:\\n\\n```text\\nchild chunk A: \\\\x1b[?1049h\\\\x1b[4;3H\\nrc injection:  \\\\x1b[2;6r\\\\x1b7\\\\x1b[1;1H\\\\x1b[2K...banner...\\\\x1b8\\nchild chunk B: To\\n```\\n\\nWithout rc injection, `To` begins at row 4, column 3. With it, DECSTBM resets the cursor before rc saves it, and chunk B begins at the restored margin-home/left position.

Represent terminal columns, including an explicit continuation cell for a width-2 primary glyph; attach width-0 combining marks to the preceding grapheme; clear an entire glyph when either half is overwritten; preserve/repair continuation invariants across editing and resize; emit a wide primary exactly once and emit no printable byte for its continuation. Merely changing `col += width` without continuation cells is insufficient because absolute overwrite, erasure, insertion/deletion, and resize would retain torn glyph halves or phantom gaps.\n\nFOCUSED REGRESSION: add a stateful differential test beside the existing `screen.rs:893+` repaint tests. Feed the exact sequential 3×10 trace above, synthesize the repaint, apply it to an independent tiny width-aware VT oracle, and assert row 2 is blank and row 3 begins `Search`; current code deterministically leaves `To` at row 2, columns 1–2. The oracle must not reuse `ScreenGrid::put_char`, or the defect will self-mask. Add boundary assertions for overwrite through either half of a wide glyph, a wide glyph at the penultimate column, ICH/DCH/ECH/EL across a continuation, clipping on resize, and a zero-width combining mark.\n\nRANK 2 — HIGH as a compounding path when enabled, but disabled on current main: rc’s `StatusRow` is a second renderer injecting terminal state outside both the child TUI and server grid. `crates/spt/src/rc.rs:199-208` sets `STATUS_ROW_ENABLED = false`; `status_row_active` at 210-216 therefore constructs no row for controllers or viewers. `traceable-reqs.toml:1603-1606` explicitly records why: the one-shot absolute banner scrolls away and its DECSC/clear/SGR injection splices into in-flight harness drawing. A screenshot that visibly contains the identity banner therefore came from an older binary, a locally re-enabled build, or another non-current-main configuration `[INFERENCE]`.\n\nWhen enabled, `StatusRow::assert_bytes` at `rc.rs:236-247` emits DECSTBM before `StatusRow::repaint_bytes` at 249-271 saves the cursor:\n\n```text\nESC[2;Rr ESC7 ESC[1;1H ESC[2K ESC[1;COLH ESC[36m <identity> ESC[0m ESC8\n```\n\nDECSTBM changes the cursor before DECSC, so rc saves/restores the post-margin cursor rather than the child’s pre-overlay cursor. DECSC/DECRC also share the emulator’s single DEC saved-cursor slot with the child. The repository’s terminal model shows the underlying mismatch: CUP/HVP is absolute at `screen.rs:791-795`; DECSTBM changes margins and resets the cursor at 808-817. A scroll region is not a vertical coordinate translation.\n\nThe output splice is exact at `rc.rs:2286-2303`: rc writes a complete child Output chunk verbatim, scans that chunk, then appends the banner assertion if it saw alt-screen enter or DECSTBM reset. PTY chunks are not TUI-frame boundaries. Minimal schedule:\n\n```text\nchild chunk A: \\x1b[?1049h\\x1b[4;3H\nrc injection:  \\x1b[2;6r\\x1b7\\x1b[1;1H\\x1b[2K...banner...\\x1b8\nchild chunk B: To\n```\n\nWithout rc injection, `To` begins at row 4, column 3. With it, DECSTBM resets the cursor before rc saves it, and chunk B begins at the restored margin-home/left position. This is logical-frame interleaving even though individual `write_all` calls are sequential and byte-complete.\n\nThe geometry is also invalid for an absolute-addressed child. `attach_viewport` at `rc.rs:1870-1882` gives the PTY `physical_rows - 1` but does not translate the child’s CUP coordinates; Claude’s `CUP 1;n` still addresses physical row 1 and can overwrite the supposed reserved row. The initial resize is sent at 1874-1882; `pump` starts with `last_size = None` at 2190-2194 and sends the same size again on its first loop, immediately adding another status assertion at 2210-2225. Resize is forwarded at `crates/spt-daemon/src/attach.rs:498-506` and applied to the PTY/grid at `broker.rs:4446-4466`, so ConPTY/Claude redraw can race semantically with those one-shot paints.\n\nFIX SEAM for rank 2: the immediate production fix is already correct—keep `STATUS_ROW_ENABLED = false`, ensure the controller uses full terminal dimensions, and add a real controller-path assertion that no status bytes or row subtraction occur. A permanent identity UI must be composed by one authoritative renderer on every frame with explicit physical layout; it must not be restored by re-enabling the rc raw-byte injector. The existing `ScreenGrid` is the natural future ownership seam, after its Unicode cell model is fixed.\n\nRANK 3 — MEDIUM: cold repaint at old geometry followed by controller resize/live child repaint can amplify the corruption. The cold repaint can already be queued when rc sends the initial size. `broker.rs:1442-1447` changes grid geometry on resize but cannot retract an already queued repaint; the duplicate initial resize increases redraw churn. This is a composition stressor, not as exact an explanation of `To`/`Wh`/`Es` as rank 1.\n\nRANK 4 — LOW/currently closed: ScreenGrid previously omitted DECSTBM from cold repaint. ADR-0043 identifies it, but `screen.rs:610-629` now emits the tracked region or explicit `ESC[r` before final cursor placement; tests at 893-936 cover post-repaint scroll equivalence.\n\nRANK 5 — LOW/refuted for the active settings screenshot: Windows Terminal is expected to implement Unicode width and the cited VT controls; the malformed authoritative repaint exists server-side first. Legacy conhost DECSC quirks can worsen rank 2 but are not needed. Final Output-before-Exit ordering and `DisplayGuard` teardown (`rc.rs:858-898`, 1529-1590) act when the viewport ends, not while the settings TUI is active. The DSR auto-answer in `crates/spt-term/src/reader.rs:31-36,118-143` can produce a fixed CPR plus a delayed physical CPR, but it is a separate protocol concern and does not deterministically produce two-character wrap scraps.","files":[{"path":"crates/spt-term/src/screen.rs","description":"Primary defect and fix seam.

The broker both forwards raw live chunks and advances a server-side authoritative `ScreenGrid`. A cold controller attach receives one synthesized grid repaint instead of raw history, then unchanged raw live frames. rc writes those Output bytes to the physical terminal. Therefore the layers separate cleanly: the child’s original width-aware screen can be correct; the scalar-based server grid can reconstruct it incorrectly; the physical terminal can faithfully execute the incorrect repaint; and an enabled rc StatusRow can independently mutate the same VT state outside both render models. The exact screenshot-class scraps arise in the server layer: two unmodeled continuation columns make a synthesized row two display cells too wide, its last two characters wrap into a row the grid believes blank, and repaint skips that row. The visible rc banner identifies an additional old/enabled out-of-band renderer, but current v0.38.x main intentionally disables it.
