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: **VT State-Machine Investigator**. Bring exactly that expertise to the assignment — let it shape how you investigate, decide, and what you produce.\n\nCONTEXT\n===================================\n\n# Goal\nDiagnose spt-hosted Claude Code settings TUI corruption from supplied screenshot: row immediately above `Search settings...` is shifted left two columns; scrap fragments `To`, `Wh`, `Es` remain in left margin; rc identity banner at bottom. Find exact source seam and report only.\n# Constraints\nRead-only. Skip edits, formatters, linters, and project-wide tests. Current tree is v0.38.x main. Use CONTEXT/ADR/Known Hazards semantics. Return exact files/symbols/lines and deterministic regression.\n# Contract\nSeparate child TUI output, server ScreenGrid/repaint, rc status overlay/PTY resize, terminal emulator behavior, and final-output ordering.\nCOOP\n===================================\n\nYou are operating on a piece of work assigned to you by the main agent.\n# IRC Peers\nYou can reach other live agents via the `irc` tool.

Address peers by id or use `\"all\"` to broadcast.\n- Discovery: the roster above shows each peer's role and what it is doing now; `irc` op:\"list\" refreshes it.\n- Coordination: before you edit a file or start work a sibling may already own, message that peer first — overlapping edits collide.\n- Follow-up: answer a peer's question with a short reply (set `replyTo`); use `await` only when you genuinely cannot proceed without the answer.\n\nCOMPLETION\n===================================\n\nNo TODO tracking, no progress updates. Execute; report results with `yield`.\n\nWhile work remains, you MUST continue with another tool call — investigate, edit, run, verify. Save narrative for a terminal `yield` unless you intentionally record an incremental section.\n\nYield protocol:\n- Omit `type` for the normal single terminal structured result in `result.data`.\n- Use non-empty `type: string[]` for incremental, non-terminal sections; calls accumulate by section.\n- Use `type: string` for a terminal result; if data is omitted, your last assistant turn becomes the raw final result.\n\nThis is your only way to return a final result. For structured results, you NEVER put JSON in plain text or substitute a text summary for `result.data`.\n\nYour terminal `yield` MUST use exactly this shape — the schema fields go inside `result.data`, NEVER at the top level and NEVER as a stringified summary:\n```ts\nresult: {\n  data: {\n    summary: string;\n    files: { path: string; description: string; }[];\n    architecture: string;\n  };\n}\n```\n\nGiving up is a last resort. If truly blocked, you MUST terminal-yield `result.error` describing what you tried and the exact blocker.\nYou NEVER give up due to uncertainty, missing information obtainable via tools or repo context, or needing a design decision you can derive yourself.\n\nYou MUST keep going until this ticket is closed.

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

Reproduce → minimise → hypothesise → instrument → fix → regression-test. Use when user says \"diagnose this\" / \"debug this\", reports a bug, says something is broken/throwing/failing, or describes a performance regression.\r\n---\r\n\r\n# Diagnose\r\n\r\nA discipline for hard bugs. Skip phases only when explicitly justified.\r\n\r\nWhen exploring the codebase, use the project's domain glossary to get a clear mental model of the relevant modules, and check ADRs in the area you're touching.\r\n\r\n## Phase 1 — Build a feedback loop\r\n\r\n**This is the skill.** Everything else is mechanical. If you have a fast, deterministic, agent-runnable pass/fail signal for the bug, you will find the cause — bisection, hypothesis-testing, and instrumentation all just consume that signal. If you don't have one, no amount of staring at code will save you.\r\n\r\nSpend disproportionate effort here. **Be aggressive. Be creative. Refuse to give up.**\r\n\r\n### Ways to construct one — try them in roughly this order\r\n\r\n1. **Failing test** at whatever seam reaches the bug — unit, integration, e2e.\r\n2. **Curl / HTTP script** against a running dev server.\r\n3. **CLI invocation** with a fixture input, diffing stdout against a known-good snapshot.\r\n4. **Headless browser script** (Playwright / Puppeteer) — drives the UI, asserts on DOM/console/network.\r\n5. **Replay a captured trace.** Save a real network request / payload / event log to disk; replay it through the code path in isolation.\r\n6. **Throwaway harness.** Spin up a minimal subset of the system (one service, mocked deps) that exercises the bug code path with a single function call.\r\n7. **Property / fuzz loop.** If the bug is \"sometimes wrong output\", run 1000 random inputs and look for the failure mode.\r\n8. **Bisection harness.** If the bug appeared between two known states (commit, dataset, version), automate \"boot at state X, check, repeat\" so you can `git bisect run` it.\r\n9. **Differential loop.** Run the same input through old-version vs new-version (or two configs) and diff outputs.\r\n10. **HITL bash script.** Last resort. If a human must click, drive _them_ with `scripts/hitl-loop.template.sh` so the loop is still structured. Captured output feeds back to you.\r\n\r\nBuild the right feedback loop, and the bug is 90% fixed.\r\n\r\n### Iterate on the loop itself\r\n\r\nTreat the loop as a product. Once you have _a_ loop, ask:\r\n\r\n- Can I make it faster? (Cache setup, skip unrelated init, narrow the test scope.)\r\n- Can I make the signal sharper? (Assert on the specific symptom, not \"didn't crash\".)\r\n- Can I make it more deterministic? (Pin time, seed RNG, isolate filesystem, freeze network.)\r\n\r\nA 30-second flaky loop is barely better than no loop. A 2-second deterministic loop is a debugging superpower.\r\n\r\n### Non-deterministic bugs\r\n\r\nThe goal is not a clean repro but a **higher reproduction rate**. Loop the trigger 100×, parallelise, add stress, narrow timing windows, inject sleeps. A 50%-flake bug is debuggable; 1% is not — keep raising the rate until it's debuggable.\r\n\r\n### When you genuinely cannot build a loop\r\n\r\nStop and say so explicitly. List what you tried. Ask the user for: (a) access to whatever environment reproduces it, (b) a captured artifact (HAR file, log dump, core dump, screen recording with timestamps), or (c) permission to add temporary production instrumentation. Do **not** proceed to hypothesise without a loop.\r\n\r\nDo not proceed to Phase 2 until you have a loop you believe in.\r\n\r\n## Phase 2 — Reproduce\r\n\r\nRun the loop. Watch the bug appear.\r\n\r\nConfirm:\r\n\r\n- [ ] The loop produces the failure mode the **user** described — not a different failure that happens to be nearby. Wrong bug = wrong fix.\r\n- [ ] The failure is reproducible across multiple runs (or, for non-deterministic bugs, reproducible at a high enough rate to debug against).\r\n- [ ] You have captured the exact symptom (error message, wrong output, slow timing) so later phases can verify the fix actually addresses it.\r\n\r\nDo not proceed until you reproduce the bug.\r\n\r\n## Phase 3 — Hypothesise\r\n\r\nGenerate **3–5 ranked hypotheses** before testing any of them. Single-hypothesis generation anchors on the first plausible idea.\r\n\r\nEach hypothesis must be **falsifiable**: state the prediction it makes.\r\n\r\n> Format: \"If <X> is the cause, then <changing Y> will make the bug disappear / <changing Z> will make it worse.\"\r\n\r\nIf you cannot state the prediction, the hypothesis is a vibe — discard or sharpen it.\r\n\r\n**Show the ranked list to the user before testing.** They often have domain knowledge that re-ranks instantly (\"we just deployed a change to #3\"), or know hypotheses they've already ruled out. Cheap checkpoint, big time saver. Don't block on it — proceed with your ranking if the user is AFK.\r\n\r\n## Phase 4 — Instrument\r\n\r\nEach probe must map to a specific prediction from Phase 3. **Change one variable at a time.**\r\n\r\nTool preference:\r\n\r\n1. **Debugger / REPL inspection** if the env supports it. One breakpoint beats ten logs.\r\n2. **Targeted logs** at the boundaries that distinguish hypotheses.\r\n3. Never \"log everything and grep\".\r\n\r\n**Tag every debug log** with a unique prefix, e.g. `[DEBUG-a4f2]`. Cleanup at the end becomes a single grep. Untagged logs survive; tagged logs die.\r\n\r\n**Perf branch.** For performance regressions, logs are usually wrong. Instead: establish a baseline measurement (timing harness, `performance.now()`, profiler, query plan), then bisect. Measure first, fix second.\r\n\r\n## Phase 5 — Fix + regression test\r\n\r\nWrite the regression test **before the fix** — but only if there is a **correct seam** for it.\r\n\r\nA correct seam is one where the test exercises the **real bug pattern** as it occurs at the call site.

No Unicode width dep/continuation/combining support anywhere in spt-term; ICH/DCH/ECH/ED/EL operate scalar slots (347-439). Deterministic stale-2 seam: feed UTF-8 `界界Today\\x1b[1;5HNEW` to 1x20 grid. Real VT: two width-2 glyphs put Today at col5, CUP 1;5 overwrites T/o/d => `界界NEWay`. Grid stores wide glyphs as 1 each, so CUP col5 overwrites d/a/y and cold repaint carries `界界ToNEW`: exact stale `To` prefix caused by 2-column width deficit. Same shape can yield Wh/Es. Repaint starts `?1049*,0m,2J,H` (577-607), so it cannot preserve pre-existing physical scraps; it clears then paints its corrupted model.

The source seam is the width model, not byte loss in the daemon writer. `Cell` stores one Rust `char` per grid slot (`screen.rs:122-145`), and `put_char` advances exactly one column for every Unicode scalar (`screen.rs:327-344`). There is no wide-lead/wide-continuation representation, no combining/grapheme attachment, and no Unicode-width dependency in `spt-term`. Consequently, a width-2 glyph consumes one server cell but two cells in Windows Terminal. The synthesized repaint then emits the server row as a sequential Unicode string after an absolute CUP (`screen.rs:598-607`). If the server row is full according to scalar count but two columns overfull according to terminal display width, its final two characters wrap into the next physical row. When that next row is default-blank, `render_repaint` skips it, so nothing overwrites the newly wrapped characters. The leading `ESC[2J` does not refute this mechanism: it clears old residue before painting, while these scraps are created afterward by the repaint itself.\n\nDeterministic byte-level regression seam `[INFERENCE]`: use a 3×10 stateful reference terminal. Feed the authoritative/original terminal and `ScreenGrid` this byte trace: `ESC[1;1H` + UTF-8 `界界ABCDEFTo` + `ESC[2;1H ESC[2K ESC[3;1HSearch`. On a display-width-aware terminal, the two `界` glyphs occupy four columns; `ABCDEF` fills the rest of row 1; `To` legitimately wraps to row 2, and the following CUP+EL clears row 2. The correct final screen therefore has row 2 blank immediately above `Search`. `ScreenGrid` instead stores all ten Unicode scalars in row 1 because each `界` costs one cell; its EL sees row 2 already blank. Its repaint re-emits a 12-display-column row 1, falsely wraps `To` into physical row 2, skips modeled-blank row 2, and then CUP-paints `Search` on row 3. Substituting row suffixes `Wh` or `Es` produces the other reported fragments. A second deterministic seam is `界界Today ESC[1;5HNEW`: a real terminal overwrites the start of `Today` at display column 5, while the scalar-cell grid overwrites `day` and retains the false prefix `To`.\n\nThe regression must be differential and stateful: process the original trace in a real/reference VT grid, process `ScreenGrid::render_repaint()` in a fresh instance of the same emulator, and compare physical cells. Do not compare `ScreenGrid` to another `ScreenGrid`; the existing stateful-looking test at `screen.rs:915-934` uses the same faulty model on both sides and cannot detect a shared width bug. Add the corresponding broker seam by feeding the trace through `OutputLog::append`, cold-subscribing from sequence 0, decoding the one output frame, and applying it to the reference emulator. Current code should fail with `To` in row 2.\n\nSupported mechanisms:\n- **Wide/zero-width handling: implicated.** Wide glyphs, combining characters, variation selectors, and ZWJ sequences are all represented as independent one-column `char` cells. This directly supports both two-column row drift and two-character wrap scraps.\n- **ICH/DCH/ECH/ED/EL over wide glyphs: implicated as amplifiers.** `erase_display`, `erase_line`, `erase_chars`, `insert_chars`, and `delete_chars` operate on scalar slots (`screen.rs:347-439`). Their narrow-ASCII ranges are otherwise straightforward, but without lead/continuation invariants they cannot erase or move a whole width-2 glyph atomically. The absolute-overwrite trace above shows the same class without requiring ICH/DCH.\n- **Repaint trimming: not independently wrong, but exposes the width bug.** Trimming only trailing default blanks after a full clear is semantically safe for a width-correct model. It becomes the decisive persistence step when a preceding over-wide row wraps into a modeled-blank row that is skipped.\n- **DECSTBM: refuted for this horizontal two-column shape on current main.** The grid tracks margins (`screen.rs:208-209`, `808-817`) and the repaint now emits either the tracked region or explicit `ESC[r` before final cursor placement (`screen.rs:618-640`). Tests cover this at `screen.rs:891-934`. DECSTBM defects move/scroll rows, not columns.\n- **Origin mode/DECOM: unsupported, but a separate vertical divergence.** There is no origin-mode field. Private mode handling recognizes only 25, 47, 1047, and 1049 (`screen.rs:469-479`); `CSI ? 6 h/l` is ignored, while CUP/VPA coordinates remain absolute (`screen.rs:754-795`). Repaint never restores DECOM. This can make subsequent raw cursor addressing differ vertically relative to the scroll region, but it does not explain deterministic two-column left-margin fragments.\n- **Synchronized updates (`?2026h/l`): unsupported, but a separate snapshot-atomicity risk.** Mode 2026 is ignored by the same `set_mode` switch. `Drain` forwards arbitrary reads of up to 8192 bytes (`reader.rs:117-148`), and each read is advanced into the grid independently. A cold attach can therefore snapshot between chunks of a synchronized frame even though a physical terminal would keep the old committed frame visible until `?2026l`. This can expose a transient mixed frame, but it does not specifically generate a stable horizontal offset without an accompanying width/cursor error.\n- **Writer path: refuted as a byte-mutating source.** `OutputLog::append` base64-envelopes the original chunk for live controller/viewer fan-out and advances the grid only after that fan-out, under the same log lock (`broker.rs:935-994`). A cold `from_seq == 0` attach substitutes exactly one synthesized repaint (`broker.rs:836-851`, `1064-1088`, `1290-1303`); resume attaches keep raw ring bytes. `controller_writer` writes the initial repaint before draining the live FIFO (`broker.rs:1810-1937`), and `viewer_writer` does the analogous initial-then-live order (`broker.rs:1634-1681`). Thus the grid can affect only the cold repaint; an already-live attachment receives unchanged child bytes. If the screenshot was produced without a cold attach/reconnect, this particular ScreenGrid mechanism is refuted for that occurrence.\n- **Exit/final-output ordering: refuted in the healthy current path.** ADR-0043 is implemented by queueing `Exit` behind output through the same per-sink writer. The controller loop handles `CtrlMsg::Output` then `CtrlMsg::Exit` FIFO (`broker.rs:1914-1941`). There remains an explicitly loud three-second wedged-sink fallback that direct-writes Exit (`broker.rs:1745-1772`), but that is a terminal/wedge degradation, not a two-column grid transformation.\n- **Resize: a real secondary server-grid race, not needed for the deterministic wide-glyph repro.** `dispatch_resize` resizes the physical PTY first and only afterward locks and resizes the grid (`broker.rs:4447-4467`). `GridState::resize` merely copies the top-left overlap and resets margins (`screen.rs:557-567`). On ConPTY, resize-triggered repaint bytes may be drained between those operations and interpreted at the old grid width, creating wrap/crop debris in a later cold repaint. This should be closed or serialized, but the width repro already establishes the requested screenshot shape without relying on timing.\n\nRecommended fix: replace `Cell { ch: char, pen }` with a display-cell invariant that distinguishes blank, glyph lead (with display width and complete grapheme/combining payload), and wide continuation. Use an explicit, pinned terminal-width policy as a direct dependency; attach zero-width scalars to the preceding glyph rather than advancing the cursor. Printing must reserve both cells for a width-2 glyph and apply terminal-compatible right-margin behavior. Overwrite, ED/EL/ECH, ICH/DCH, scrolling, and resize must clear/move entire glyphs and repair orphan leads/continuations at operation boundaries; resize must sanitize a wide glyph clipped at the right edge. Repaint must emit glyph leads once, skip continuation cells, and guarantee that the display width emitted for a modeled row never exceeds `cols`.

It supports treating an rc identity/status banner as a separate client overlay rather than ScreenGrid-generated PTY content."}],"architecture":"The relevant path is: child TUI → OS PTY/ConPTY byte stream → `Drain::spawn` ordered read chunks → `OutputLog::append`. `append` sends the original bytes unchanged to existing controller/viewer queues and independently interprets them into the broker-owned `ScreenGrid`. For a cold attach only, `repaint_initial(0)` snapshots that grid and synthesizes one ANSI repaint. The dedicated sink writer writes that repaint, then writes subsequent raw live frames FIFO. Therefore there are two renderer domains that must not be conflated: (1) the child/terminal protocol, whose live bytes Windows Terminal interprets directly, and (2) the broker's reconstructed current-screen model, used only to establish a cold client baseline. The confirmed defect is exclusively at the second domain's Unicode-scalar-to-display-cell boundary.\n\nThe physical client terminal is the final width authority. `render_repaint` first selects main/alt, resets SGR, clears, and homes; it then CUP-addresses every modeled nonblank row and emits its scalar contents. Because server and client disagree about display width, a logically full server row can physically wrap. Blank-row elision then preserves the just-created wrapped suffix. This cleanly explains why apparently stale `To`/`Wh`/`Es` can appear even though the repaint issued a full clear and no daemon writer dropped spaces.\n\nThe rc identity/status banner is outside this server grid: no `ScreenGrid` or broker writer symbol creates such prose. It is a client overlay/final-output concern and can independently invalidate a renderer baseline, as ADR-0043/KH 7.47 describe. Likewise, PTY resize is controller-owned: the OS surface changes geometry and may emit a ConPTY repaint, while the broker later changes its own grid geometry. That ordering is a separate race and can intensify wrap artifacts, but it is not required for the deterministic width failure. Final-output ordering is another independent axis: current healthy writer queues sequence Output before Exit, so an rc banner appearing at the bottom does not establish that ScreenGrid appended it or that Exit overtook bytes.\n\nThe correct acceptance test topology is a differential triplet: original child bytes → reference stateful terminal A; the same bytes → `ScreenGrid` → synthesized repaint → fresh reference stateful terminal B; assert A and B have identical physical cell grids, cursor, active buffer, modes, and margins. Then pass the synthesized repaint through the broker cold-attach socket and assert terminal C equals A. This catches display-width, continuation, erase/cursor, DECSTBM/DECOM, synchronized-update, resize, and writer-order defects at their actual boundaries without allowing `ScreenGrid` to validate itself."}}}}],"api":"openai-codex-responses","provider":"openai-codex","model":"gpt-5.6-sol","usage":{"input":345,"output":4590,"cacheRead":114176,"cacheWrite":0,"totalTokens":119111,"reasoningTokens":1469,"cost":{"input":0.0017250000000000002,"output":0.13770000000000002,"cacheRead":0.057088,"cacheWrite":0,"total":0.19651300000000002}},"stopReason":"toolUse","timestamp":1784434622061,"responseId":"resp_01e0351ffe70697a016a5c4fbe3eb4819ba1268814ded1bc16","providerPayload":{"type":"openaiResponsesHistory","provider":"openai-codex","dt":true,"items":[{"id":"rs_01e0351ffe70697a016a5c4fbfb184819b86adc64982e5ecab","type":"reasoning","content":[],"encrypted_content":"gAAAAABqXE_RLz_2VjWvYHDRAn0-Oh8uNv8Pqpo4z3t1r80qBxtyhN_iiMGmUEHQUQtWe94KHidCTa13B7cWj5ef3tv3U5b35cic7zsQPeJ5o0OCAr4HYpgVxgNJEjKcWyshc-7yGw3zDYsUfoZMCalhI21RNjkZXIwVelzD5fqTP2aK5IFmcfGRFFVQHoTlS1uFyyYWbE34sgni30Ou8_P1f1J3E0Q19ntYvzKZ95M3_5s5fsCXKy0UNLC4wVkeOA4yDIB4lJjAV-8KITqiFMTxKWm5v4PCaTRihnFr4Rs2oSiWhh3WZsWqT2oTZfK-B212XGLs3o90OtUoSRCH-ZYUjxz7uc7lNaLnLOtFEec96grH4GvzHwR6DW-AXJZcn8XEOAsh3mu3E6SR2vnFwyJqVn2BFlcTaqJ9_NjMt-fcvIntOwHRukwiwOKNbCVFYe-WJAVrvxKglYqD0w3qC4W99ZR--w_jYm0lSmDb7Veu49gZCHA9gtbUaPnNpgQaBYgojLRxD-BYke1ASfyFW-pgwxQmm7PGWHLBxk6r3YfNSUFtNToZZgY9kcsNyJtfJXkdsYQcKWad6EhEdIGQFEOoxJsVB-IwdR0_Vo9m1kwMQERn2257m2Ws65NhuPgHRW5qFDjvMvHEyeWsL2UyBo8DDTwGFE87HfOj3C0gdbWrE-lkjy9f2qJ8vJSasWkyyS564VlDD5YlsxpHSpuYipGnTnsyqAZJbQQoM3zL8ruBP3mA3n8fYf9lSGyYyfwpInjFIHnShsvhMEcbsFbH8TUDODBGjhets-fBdA2wfY7h-k_5sib1LpvDpSv7vS6dLgJjGT0dEQMjGB_bL2LTXIICxpnpnBouv6U0tI-LeSGTkK-6HQsAaRE1EYfI1vyde2GJny96pxoxJpqSx-n_yOD3eYg_mVt8AXmAYxJDCILNG_n1SW-uVTJXyYP4VYe8sRPwlX6HN-nhX6_A_JottROJ1N-IZoNdyh0lUHlr4QlgbTVuU4HbYlMCNH67hVwpbuwPwaUYX40ntAIEFtDG09hQYha0JG_9AYUq1-oa7v4Viqh890twu4Lpfj2Aovew4jjSiwk2sUttlGxoVxUyO_iyhz9Aj6gx46i4B7FXP8YEXWH1l0tegaP2vSv_YFVC9_QqPIstZjudgkHwn0uNhc1qEb8RGwBEDhVMocp3f-gqmPXPlj-qytCmaRAikn3GNSY0yE4V5e4D8en7Eo-NsPPsb_12N8mYCwsOUEyTHy41pV1cuR0n5DDdMZrdfUVRf06KiO-q1Lzr9FOMvUHsJX1WspO95j6sbUujEIoeFKewfZsbnR-1rVJosBW-suDJEYwf0PfnMFz-H5wPPTMd04fS2jgfhZAphrCymJHlcnFG55BE-UKJkwFrMxVsm2nB8GGJLaYvognXGY5GkH1srXcJ33ukyplmnOFvlcojSbjEvu_7gglzzyIouocgj8YYh1xYYuDvB_ZrImddYyjIlQlamZf7kqpFGi4uNuvjuk7X8nmX_qka2DRkJ3UHxnZU2mWvjClaxmhhc2chr4US9pfDw40GRQPMgrW4kyGGpG8QowcRprTUzSigrpVKwgc_UWUKyYuq-Lid_b9vdZaNE2Ayqd1Z_vrld-DEHxmmqJINro6Fsgh33R1wHEMQRNU6P-Y6aD4I_Fccb3Ujp9ChZ5ilGjUW9PDxZ4p3KwXgVOHqzz4Qp2EcIeyVoAiNkm2l-18He9SkyjRHZtto5hE7ramnbYJHd83iXunee9g_NCWm_ls3P2JdOQIKHHTVV-QHUR4i-LQXUZrDizJVjYofuoKyRzJNO5dCFNRQrq2sjgcl3eNKLGBaER8-rl1fMSYbHX5FCKN8oOWXLwL5PLQDQdnqOLPQLbTjK6yFSx4_CYqMwi2z9KZCR-tRe-nD9_fVcPJ5_ApOpCk2-Ts-b2-RsTRvY1htaORKxiICfz1SrVLKjAIWlll79DWyxte3ju0QB2LsFCPRGqRjVYm_XtnUYB2-HkPXC1N67u8j2RbefqhJ8i0hgynoyv8tPcpJqCAloriT-IowijbU8UOnvi4cK27u3XGi1ba_fFUBMIZfgkNjphXWjW55K_CfTfd9MdctYELxWxaRJmjVcnCPto0yVtbzbhaGwIDNs_xh0o-KP4NmMij2rFwGfyTe8s_iiyVzVooUC-4xx1jRJGaeSXl53_LKE1QkEWO9AolDKNKAOvhY0tUr_Yv3qCISiabVUutyuZJaNH3Zi25NVPx1HH7gYDdObb4-hsYwbd-mF1wV1DC7Xe8m2bZWv9L8qiz1sKQ2-oRuIxBISC57vSAvse1_ApxGFQCtkbKnYEN5siNa-EfpakDvTgV-Sci4FbAMezTAM5Z5s-EUrUMYvkSMO2gvQuM4cOoXGiSl7cSwlnfGPvVDrX1e1cOsghrdYHODNaQLxIG9NZWwyM1zQyEoaB8g_mkXY6pQgSPIHZonRRTR9Efkdl6xk01DjulxiY9lxAY7xkAKA_UsvNmuPndOAqNprKu9ghDQLlFHwy3dvJWNQaP2mjKxeAycI3s1cxsKOCaVAzqj2hbcAidoW--cY3IKOBcTR-SLNfc9VWa7iseFiMtsNDNBg1Y71wPJUSnReMbmkDTGEAqFgu31e3VD9ImQTbLhViAi_XuzRhF6g5RJyyaZ-5LOzyZs6Timhee-OHNNeU3erOafom2S6_pNMaMFkgdaa-FWwLW2sDwb__S2Mjs_mIa0tVdZRnevSIKfPI0fu4M49UjVsbfS7p4aG8vUFXzWoB0SjvCc1qaopgRsSHGUCeJGw4JeVKtqn-otKtwuD3v-vrhCcQjNd9lEgQEcQ0L1CUlxfHnrdrnk1FSIGvKcTO3AbO9-E6E3CR4xI6QdCrc3_4ix8cQGid166kV2zP51KXPQ-u9YMuqmWvfksZ65RibOvYkvkPQz30UFOL-0qrm-C0loFchlFbcKXoxha6hDVAkze0S-D0d2qw6OPFvi-Ihu68bTXdN4aQcQHgVwLIU_EdiL17D6rKOie3AqNrPsZCL6ckCqpxeUs08HC5KasR8EhM8_XCWBj60aFdtRCesX-TLuK6723Xg-gqhFyGQ4onHuksGvRp63_snAlmssi-T36YRy84WM2cj114bhd1zoMbTd991nUKzBQuimjnbQUV5a4kL-jSOkL-XFNp8fRTf4mlpRcLsBl1IadvTUUrxje8Hn5aWq_vRsn3K5B7oTYcPPpvehchtyCfG59NS4O4p17MTaIsFWT-HEZEqs1e9_iYza4pdTvYwK7H5buc-ID8ZhBY7TWEnluuuXIybw6KDTZIzbntBosx-JygSldpqk8qeJoXUgGJLjVCZsXjTce8NAp0Qp7rpHzrWugyvsZm-_VEjqqj5FHBnOQBTl2zhyr5yYSB_IjSqh5Vse7k3PwbMOMJPPLwR_Nh-SodcZoYc3Ej4WpPcro8tahivT08wRHJiYFSgCTvoL4v_DDUBUflnew3Rffeh5m7nXpPIimEG9ttJTQjAPFzTncrtvALmnN9u_WMgHqVq18JUv0O75yNDtV0dgc9Y-0JXr4pR1MhmEBtpgYMk-_fwnsXyjctwVEYvHvKv8XPYso8OPzHasC92EQDec8eYkvusI5afzCDvKTzCmryfbgx1FJ9bIC05r_VPy5QatZ-yI73GjoCwTvS2NRGxeEmtw16p0t6HPmzQEKDuUJKksy4ey5SN6fCNFmL6eUwbw7pcezAS3alsXpcjKp5v73mjUb3nwObB5BLvd1Bs94dWhxT0xv5Q_AhwY90f3ljHahYZLIyjHUZ61vfAQa8ib3mGc_QDio07MulbGNr_AthHliuowDyabAc-c17n3PW64sQS0r2JVx5wA2Tc31RSCle0sMmN25eQwb2DWB7NKWMuOJbvIYP55gKEATKgr8YkkTpQ3x2VaZryk3BNyj_N16K8w1lIQmfbGcNGxq8sD_swC9cwIOSZ_KvnzRRiBKqhC74ZqvJPxjpdfbCtmFuXdIf-ROuGk6MCqJtHilSwBGpWzdD1zP5SkXB9qNUtkpJvNvdsSVgxMLbJwYJHVQPfhcEs-rfCIo38QG6wx5hRRC9McjFwFp0f0eyysIYGTvOJfmPXzDtmskC5oGXZF83xOjOAiHc-0PcbddMYRpGjn4PGL0MgUYRbATdnsEWI1MNaZJzj1dU8UipkAqUgHeOInbw8aOCi13PPPNlT6eLoZGllXDvagR54_c4Fz__F1YKNpqzObaP4VewY7-e3VfeNxNZZSwJiA7p-bdp_tsSiDtP-SKf8QLfent0oGwGVFIPv4HazservbUq79BP8nbfaUw8WE1Pte4c

server-side `ScreenGrid` is capable of manufacturing the reported two-character left-margin scraps during a cold attach/reconnect repaint. The source seam is the width model, not byte loss in the daemon writer. `Cell` stores one Rust `char` per grid slot (`screen.rs:122-145`), and `put_char` advances exactly one column for every Unicode scalar (`screen.rs:327-344`). There is no wide-lead/wide-continuation representation, no combining/grapheme attachment, and no Unicode-width dependency in `spt-term`. Consequently, a width-2 glyph consumes one server cell but two cells in Windows Terminal. The synthesized repaint then emits the server row as a sequential Unicode string after an absolute CUP (`screen.rs:598-607`). If the server row is full according to scalar count but two columns overfull according to terminal display width, its final two characters wrap into the next physical row. When that next row is default-blank, `render_repaint` skips it, so nothing overwrites the newly wrapped characters. The leading `ESC[2J` does not refute this mechanism: it clears old residue before painting, while these scraps are created afterward by the repaint itself.\\n\\nDeterministic byte-level regression seam `[INFERENCE]`: use a 3×10 stateful reference terminal. Feed the authoritative/original terminal and `ScreenGrid` this byte trace: `ESC[1;1H` + UTF-8 `界界ABCDEFTo` + `ESC[2;1H ESC[2K ESC[3;1HSearch`. On a display-width-aware terminal, the two `界` glyphs occupy four columns; `ABCDEF` fills the rest of row 1; `To` legitimately wraps to row 2, and the following CUP+EL clears row 2. The correct final screen therefore has row 2 blank immediately above `Search`. `ScreenGrid` instead stores all ten Unicode scalars in row 1 because each `界` costs one cell; its EL sees row 2 already blank. Its repaint re-emits a 12-display-column row 1, falsely wraps `To` into physical row 2, skips modeled-blank row 2, and then CUP-paints `Search` on row 3. Substituting row suffixes `Wh` or `Es` produces the other reported fragments. A second deterministic seam is `界界Today ESC[1;5HNEW`: a real terminal overwrites the start of `Today` at display column 5, while the scalar-cell grid overwrites `day` and retains the false prefix `To`.\\n\\nThe regression must be differential and stateful: process the original trace in a real/reference VT grid, process `ScreenGrid::render_repaint()` in a fresh instance of the same emulator, and compare physical cells. Do not compare `ScreenGrid` to another `ScreenGrid`; the existing stateful-looking test at `screen.rs:915-934` uses the same faulty model on both sides and cannot detect a shared width bug. Add the corresponding broker seam by feeding the trace through `OutputLog::append`, cold-subscribing from sequence 0, decoding the one output frame, and applying it to the reference emulator. Current code should fail with `To` in row 2.\\n\\nSupported mechanisms:\\n- **Wide/zero-width handling: implicated.** Wide glyphs, combining characters, variation selectors, and ZWJ sequences are all represented as independent one-column `char` cells. This directly supports both two-column row drift and two-character wrap scraps.\\n- **ICH/DCH/ECH/ED/EL over wide glyphs: implicated as amplifiers.** `erase_display`, `erase_line`, `erase_chars`, `insert_chars`, and `delete_chars` operate on scalar slots (`screen.rs:347-439`). Their narrow-ASCII ranges are otherwise straightforward, but without lead/continuation invariants they cannot erase or move a whole width-2 glyph atomically. The absolute-overwrite trace above shows the same class without requiring ICH/DCH.\\n- **Repaint trimming: not independently wrong, but exposes the width bug.** Trimming only trailing default blanks after a full clear is semantically safe for a width-correct model. It becomes the decisive persistence step when a preceding over-wide row wraps into a modeled-blank row that is skipped.\\n- **DECSTBM: refuted for this horizontal two-column shape on current main.** The grid tracks margins (`screen.rs:208-209`, `808-817`) and the repaint now emits either the tracked region or explicit `ESC[r` before final cursor placement (`screen.rs:618-640`). Tests cover this at `screen.rs:891-934`. DECSTBM defects move/scroll rows, not columns.\\n- **Origin mode/DECOM: unsupported, but a separate vertical divergence.** There is no origin-mode field. Private mode handling recognizes only 25, 47, 1047, and 1049 (`screen.rs:469-479`); `CSI ? 6 h/l` is ignored, while CUP/VPA coordinates remain absolute (`screen.rs:754-795`). Repaint never restores DECOM. This can make subsequent raw cursor addressing differ vertically relative to the scroll region, but it does not explain deterministic two-column left-margin fragments.\\n- **Synchronized updates (`?2026h/l`): unsupported, but a separate snapshot-atomicity risk.** Mode 2026 is ignored by the same `set_mode` switch. `Drain` forwards arbitrary reads of up to 8192 bytes (`reader.rs:117-148`), and each read is advanced into the grid independently. A cold attach can therefore snapshot between chunks of a synchronized frame even though a physical terminal would keep the old committed frame visible until `?2026l`. This can expose a transient mixed frame, but it does not specifically generate a stable horizontal offset without an accompanying width/cursor error.\\n- **Writer path: refuted as a byte-mutating source.** `OutputLog::append` base64-envelopes the original chunk for live controller/viewer fan-out and advances the grid only after that fan-out, under the same log lock (`broker.rs:935-994`). A cold `from_seq == 0` attach substitutes exactly one synthesized repaint (`broker.rs:836-851`, `1064-1088`, `1290-1303`); resume attaches keep raw ring bytes. `controller_writer` writes the initial repaint before draining the live FIFO (`broker.rs:1810-1937`), and `viewer_writer` does the analogous initial-then-live order (`broker.rs:1634-1681`). Thus the grid can affect only the cold repaint; an already-live attachment receives unchanged child bytes. If the screenshot was produced without a cold attach/reconnect, this particular ScreenGrid mechanism is refuted for that occurrence.\\n- **Exit/final-output ordering: refuted in the healthy current path.** ADR-0043 is implemented by queueing `Exit` behind output through the same per-sink writer. The controller loop handles `CtrlMsg::Output` then `CtrlMsg::Exit` FIFO (`broker.rs:1914-1941`). There remains an explicitly loud three-second wedged-sink fallback that direct-writes Exit (`broker.rs:1745-1772`), but that is a terminal/wedge degradation, not a two-column grid transformation.\\n- **Resize: a real secondary server-grid race, not needed for the deterministic wide-glyph repro.** `dispatch_resize` resizes the physical PTY first and only afterward locks and resizes the grid (`broker.rs:4447-4467`). `GridState::resize` merely copies the top-left overlap and resets margins (`screen.rs:557-567`). On ConPTY, resize-triggered repaint bytes may be drained between those operations and interpreted at the old grid width, creating wrap/crop debris in a later cold repaint. This should be closed or serialized, but the width repro already establishes the requested screenshot shape without relying on timing.\\n\\nRecommended fix: replace `Cell { ch: char, pen }` with a display-cell invariant that distinguishes blank, glyph lead (with display width and complete grapheme/combining payload), and wide continuation. Use an explicit, pinned terminal-width policy as a direct dependency; attach zero-width scalars to the preceding glyph rather than advancing the cursor. Printing must reserve both cells for a width-2 glyph and apply terminal-compatible right-margin behavior. Overwrite, ED/EL/ECH, ICH/DCH, scrolling, and resize must clear/move entire glyphs and repair orphan leads/continuations at operation boundaries; resize must sanitize a wide glyph clipped at the right edge. Repaint must emit glyph leads once, skip continuation cells, and guarantee that the display width emitted for a modeled row never exceeds `cols`. This fixes the state model at the source; inserting ad hoc clears after rows would only mask one symptom. Track/replay DECOM and synchronized-update commit state separately if captured Claude bytes prove those modes are present.

The source seam is the width model, not byte loss in the daemon writer. `Cell` stores one Rust `char` per grid slot (`screen.rs:122-145`), and `put_char` advances exactly one column for every Unicode scalar (`screen.rs:327-344`). There is no wide-lead/wide-continuation representation, no combining/grapheme attachment, and no Unicode-width dependency in `spt-term`. Consequently, a width-2 glyph consumes one server cell but two cells in Windows Terminal. The synthesized repaint then emits the server row as a sequential Unicode string after an absolute CUP (`screen.rs:598-607`). If the server row is full according to scalar count but two columns overfull according to terminal display width, its final two characters wrap into the next physical row. When that next row is default-blank, `render_repaint` skips it, so nothing overwrites the newly wrapped characters. The leading `ESC[2J` does not refute this mechanism: it clears old residue before painting, while these scraps are created afterward by the repaint itself.\n\nDeterministic byte-level regression seam `[INFERENCE]`: use a 3×10 stateful reference terminal. Feed the authoritative/original terminal and `ScreenGrid` this byte trace: `ESC[1;1H` + UTF-8 `界界ABCDEFTo` + `ESC[2;1H ESC[2K ESC[3;1HSearch`. On a display-width-aware terminal, the two `界` glyphs occupy four columns; `ABCDEF` fills the rest of row 1; `To` legitimately wraps to row 2, and the following CUP+EL clears row 2. The correct final screen therefore has row 2 blank immediately above `Search`. `ScreenGrid` instead stores all ten Unicode scalars in row 1 because each `界` costs one cell; its EL sees row 2 already blank. Its repaint re-emits a 12-display-column row 1, falsely wraps `To` into physical row 2, skips modeled-blank row 2, and then CUP-paints `Search` on row 3. Substituting row suffixes `Wh` or `Es` produces the other reported fragments. A second deterministic seam is `界界Today ESC[1;5HNEW`: a real terminal overwrites the start of `Today` at display column 5, while the scalar-cell grid overwrites `day` and retains the false prefix `To`.\n\nThe regression must be differential and stateful: process the original trace in a real/reference VT grid, process `ScreenGrid::render_repaint()` in a fresh instance of the same emulator, and compare physical cells. Do not compare `ScreenGrid` to another `ScreenGrid`; the existing stateful-looking test at `screen.rs:915-934` uses the same faulty model on both sides and cannot detect a shared width bug. Add the corresponding broker seam by feeding the trace through `OutputLog::append`, cold-subscribing from sequence 0, decoding the one output frame, and applying it to the reference emulator. Current code should fail with `To` in row 2.\n\nSupported mechanisms:\n- **Wide/zero-width handling: implicated.** Wide glyphs, combining characters, variation selectors, and ZWJ sequences are all represented as independent one-column `char` cells. This directly supports both two-column row drift and two-character wrap scraps.\n- **ICH/DCH/ECH/ED/EL over wide glyphs: implicated as amplifiers.** `erase_display`, `erase_line`, `erase_chars`, `insert_chars`, and `delete_chars` operate on scalar slots (`screen.rs:347-439`). Their narrow-ASCII ranges are otherwise straightforward, but without lead/continuation invariants they cannot erase or move a whole width-2 glyph atomically. The absolute-overwrite trace above shows the same class without requiring ICH/DCH.\n- **Repaint trimming: not independently wrong, but exposes the width bug.** Trimming only trailing default blanks after a full clear is semantically safe for a width-correct model. It becomes the decisive persistence step when a preceding over-wide row wraps into a modeled-blank row that is skipped.\n- **DECSTBM: refuted for this horizontal two-column shape on current main.** The grid tracks margins (`screen.rs:208-209`, `808-817`) and the repaint now emits either the tracked region or explicit `ESC[r` before final cursor placement (`screen.rs:618-640`). Tests cover this at `screen.rs:891-934`. DECSTBM defects move/scroll rows, not columns.\n- **Origin mode/DECOM: unsupported, but a separate vertical divergence.** There is no origin-mode field. Private mode handling recognizes only 25, 47, 1047, and 1049 (`screen.rs:469-479`); `CSI ? 6 h/l` is ignored, while CUP/VPA coordinates remain absolute (`screen.rs:754-795`). Repaint never restores DECOM. This can make subsequent raw cursor addressing differ vertically relative to the scroll region, but it does not explain deterministic two-column left-margin fragments.\n- **Synchronized updates (`?2026h/l`): unsupported, but a separate snapshot-atomicity risk.** Mode 2026 is ignored by the same `set_mode` switch. `Drain` forwards arbitrary reads of up to 8192 bytes (`reader.rs:117-148`), and each read is advanced into the grid independently. A cold attach can therefore snapshot between chunks of a synchronized frame even though a physical terminal would keep the old committed frame visible until `?2026l`. This can expose a transient mixed frame, but it does not specifically generate a stable horizontal offset without an accompanying width/cursor error.\n- **Writer path: refuted as a byte-mutating source.** `OutputLog::append` base64-envelopes the original chunk for live controller/viewer fan-out and advances the grid only after that fan-out, under the same log lock (`broker.rs:935-994`). A cold `from_seq == 0` attach substitutes exactly one synthesized repaint (`broker.rs:836-851`, `1064-1088`, `1290-1303`); resume attaches keep raw ring bytes. `controller_writer` writes the initial repaint before draining the live FIFO (`broker.rs:1810-1937`), and `viewer_writer` does the analogous initial-then-live order (`broker.rs:1634-1681`). Thus the grid can affect only the cold repaint; an already-live attachment receives unchanged child bytes. If the screenshot was produced without a cold attach/reconnect, this particular ScreenGrid mechanism is refuted for that occurrence.\n- **Exit/final-output ordering: refuted in the healthy current path.** ADR-0043 is implemented by queueing `Exit` behind output through the same per-sink writer. The controller loop handles `CtrlMsg::Output` then `CtrlMsg::Exit` FIFO (`broker.rs:1914-1941`). There remains an explicitly loud three-second wedged-sink fallback that direct-writes Exit (`broker.rs:1745-1772`), but that is a terminal/wedge degradation, not a two-column grid transformation.\n- **Resize: a real secondary server-grid race, not needed for the deterministic wide-glyph repro.** `dispatch_resize` resizes the physical PTY first and only afterward locks and resizes the grid (`broker.rs:4447-4467`). `GridState::resize` merely copies the top-left overlap and resets margins (`screen.rs:557-567`). On ConPTY, resize-triggered repaint bytes may be drained between those operations and interpreted at the old grid width, creating wrap/crop debris in a later cold repaint. This should be closed or serialized, but the width repro already establishes the requested screenshot shape without relying on timing.\n\nRecommended fix: replace `Cell { ch: char, pen }` with a display-cell invariant that distinguishes blank, glyph lead (with display width and complete grapheme/combining payload), and wide continuation. Use an explicit, pinned terminal-width policy as a direct dependency; attach zero-width scalars to the preceding glyph rather than advancing the cursor. Printing must reserve both cells for a width-2 glyph and apply terminal-compatible right-margin behavior. Overwrite, ED/EL/ECH, ICH/DCH, scrolling, and resize must clear/move entire glyphs and repair orphan leads/continuations at operation boundaries; resize must sanitize a wide glyph clipped at the right edge. Repaint must emit glyph leads once, skip continuation cells, and guarantee that the display width emitted for a modeled row never exceeds `cols`. This fixes the state model at the source; inserting ad hoc clears after rows would only mask one symptom. Track/replay DECOM and synchronized-update commit state separately if captured Claude bytes prove those modes are present.
