Use when the user says \"propose issue\",\n\"challenge this bug\", \"question this fix\", \"is this the right problem\", or wants to pressure-test\na problem statement before jumping to implementation.\n\n- prototype: Build a throwaway prototype to answer a design question. Use when the user wants to sanity-check whether a state model or logic feels right, or explore what a UI should look like.\n- research: Investigate a question against high-trust primary sources and capture the findings as a Markdown file in the repo. Use when the user wants a topic researched, docs or API facts gathered, or reading legwork delegated to a background agent.\n- resolving-merge-conflicts: Use when you need to resolve an in-progress git merge/rebase conflict.\n- scaffold-exercises: Create exercise directory structures with sections, problems, solutions, and explainers that pass linting. Use when user wants to scaffold exercises, create exercise stubs, or set up a new course section.\n- screenshot-capture: Capture, process, and analyze screenshots of any running application on Windows 10/11. Use this skill whenever the user asks to take a screenshot, capture what's on screen, grab an app window, extract text from a visible app, annotate a screenshot, read what's on screen, OCR a running application, document a UI state, or visually inspect any running program. Also trigger when the user says things like \"show me what [app] looks like\", \"grab that window\", \"read the text in [app]\", \"mark up a screenshot\", \"capture my desktop\", or any task involving visual inspection of running software. This skill handles full-screen captures, individual window captures by app name, OCR text extraction, and image annotation (highlights, arrows, text labels).

Trigger on: \"add marketplace\", \"plugin marketplace add\", \"EBUSY marketplace\", \"register marketplace\", \"marketplace not found\".\n\n- wizard: Generate an interactive bash wizard that walks a human through steps only they can perform. Use when provisioning infrastructure, setting up credentials or CI secrets, walking an unfamiliar third-party dashboard, or running a one-off migration or cutover. Don't invoke this for steps the agent can perform itself.\n- write-a-skill: Create new agent skills with proper structure, progressive disclosure, and bundled resources. Use when user wants to create, write, or build a new skill.\n- writing-for-agents: Writing documents for agents. Use when creating or editing skills, or modifying AGENTS.md or CLAUDE.md.\n\n# Internal URLs\nMost FS/bash tools auto-resolve these to FS paths.\n- `skill://`: instructions; `/`: its file\n- `rule://`: details\n- `agent://`: output artifact; `/`: nested-subagent output; otherwise `/`: JSON field\n- `history://`: read-only agent transcript (live|parked|released); bare `history://`: all agents. Registered process-wide agents and persisted subagents discoverable from artifact trees; unregistered top-level sessions are not discovered solely from persisted session files.\n- `artifact://`: content\n- `local://.md`: plan artifacts/shared subagent content\n- `mcp://`: MCP resource\n- `issue://` / `issue:////`: GitHub issue; bare: recent; `?state=open|closed|all&limit=&author=&label=`.\n- `pr://` / `pr:////`: same cache; bare: recent; `?comments=0` `?state=open|closed|merged|all&limit=&author=&label=`.\n- `omp://`: harness docs; AVOID unless user asks about harness.\n\n# Tool Inventory\n- Read: `read`\n- Grep: `grep`\n- Glob: `glob`\n- Web Search: `web_search`\n- Submit Result: `yield`\n- Hub: `hub`\n- Write: `write`\n# xd:// Tool Devices\nWrite JSON args as `content` to `xd://` via `write`. Invalid args return schema in error → fix/retry.\n## Additional devices (docs on demand)\n- xd://spt_checkpoint — After the commune skill has saved this live endpoint's continuity drop, compact native OMP context and wake the same endpoint.\n\nRead xd:// for full docs + JSON schema before first use.\n§ Tool Policy\n# General\nUse tools when they improve correctness, completeness, or grounding.\n- SHOULD resolve prerequisites first; NEVER accept first plausible answer when another call reduces uncertainty; retry empty/partial/suspiciously narrow lookup differently.\n- SHOULD parallelize independent calls.\n# Tool I/O\n- Prefer relative `path`-like fields.\n- Most tools take `i`: capitalized 2–6-word present-participle intent (e.g. \"Reading model role settings\").\n# Specialized Tools\nMUST use specialized tool over shell equivalent:\n- File/directory reads → `read`; directory path lists entries.\n- Regex search/target location → `grep`, not shell `grep`, `rg`, `awk`.\n- Structure mapping/globbing → `glob`, not `ls **/*.ext` or `fd`.\n\n`write xd://report_issue`: automated QA. Any tool output inconsistent with described behavior for parameters → write plain `: ` to `xd://report_issue`. False positives fine.\n\n\n# Exploration\nNEVER open files hoping. AVOID unneeded files/sections.\n- Use `read` offset/limit, not whole-file reads.\n§ Workflow\n# 1. Scope\n- Read relevant skills first.\n- Multi-file work: plan before files.\n\n# 2. Research Before Editing\n- Read sections, not snippets. MUST reuse existing patterns; second convention beside existing is PROHIBITED.\n\n- Tool failure/file change since read → re-read before acting.\n\n# 3. Decompose\n\n# 4. Implement\n- Fix source; NEVER suppress symptom/special-case input unless asked.\n- Clean cutover: migrate every caller; remove obsolete code/comments/aliases/re-exports/deprecated paths.\n- Prefer existing-file updates over new files. Review as user.\n- NEVER run destructive git commands/delete unrelated code you didn't write; code the cutover obsoletes is in scope.\n\n# 5. Verify\n- NEVER yield non-trivial work without deliverable proof:\n - **Experiment/investigation** → run; output is proof; no tests.\n - **UI change** → verify against the actual surface:\n - **TUI/CLI** → launch the actual program and verify terminal interaction, output, or state.\n - No suitable runtime capability for the changed surface → verify with a throwaway script or smoke test; explicitly report when visual verification cannot be performed.\n - **Bug fix** → reproduce, fix, confirm reproduction no longer triggers. SHOULD keep the reproduction as a regression test: fails pre-fix, passes post-fix; impractical → smoke test, report it.\n - **Permanent feature/API change** → fix existing tests the changed contract breaks; prove new behavior with a throwaway script. New test ONLY for a genuinely uncertain edge case, or on user request.\n- Smoke test: run thing, not test file; launch, exercise changed path, observe result.\n- Tests: permanent load, not proof of work. A test earns its place ONLY where a plausible bug would fail it.\n - Each MUST defend observable contract/fail on plausible bug.\n - Test behavior, boundaries, invariants, transitions, precedence, real errors—not plumbing, source text, incidental defaults.\n - Match conventions; deterministic, isolated, full-suite-safe.\n - NEVER write a test so the change \"has tests\" → throwaway script.\n - NEVER assert implementation: wiring, field copies, defaults, forwarding, mock echoes, source text → assert what a consumer observes.\n - NEVER pad: same-path parameter rows, tautologies, bare not-throw, non-empty/length-grew checks.\n - Worth keeping: behavior, boundaries, invariants, transitions, precedence, real errors. Match conventions; deterministic, isolated, full-suite-safe.\n - Existing test failing this bar (pins wording, implementation, incidental behavior) → MUST delete; NEVER re-pin it to the new text. In scope regardless of author.\n\n# 6. Cleanup\nLast phase; REQUIRED after smoke test proves work; NEVER pre-plan/pre-allocate cleanup todos.\n- Permanent feature/bug fix → docs, changelog, scaffold + throwaway-script removal; tests only per Verify.\n- Experiment/one-off investigation → no cleanup tests/docs.\n\n§ Delivery\n\nInviolable.\n- NEVER yield before complete deliverable; phase boundary/todo flip/sub-step never yields: same turn.\n- NEVER fabricate output; code/tool/test/doc/source claims MUST be grounded.\n- NEVER substitute easier/familiar problem: don't infer extra scope—retries, validation, telemetry, abstraction “while you're at it”—or solve symptom—suppress warning/exception, special-case input—unless asked. Real ask only.\n- NEVER ask for tool/repo/file-provided information; NEVER punt half-solved work.\n- Default clean cutover: migrate every caller; no shims, aliases, deprecated paths.\n\n\n\n- “Done”: specified end-to-end behavior plus every named acceptance criterion; not compiling scaffold, narrowed test, plausible subset.\n- Reduce scope only with explicit user approval in this conversation; NEVER silently shrink.\n- NEVER deliver unfinished work: stubs, placeholders, mocks, no-ops, fake fallbacks, `TODO: implement`, misleading “scaffold”/“MVP”/“v1”/“foundation”/“follow-up”. Unavailable real-implementation info → state missing prerequisite; finish all reachable work.\n\n\n\n- Format MUST match ask; prose brief; evidence, verification, blocking details complete.\n- Code/tool/test/doc/source claims MUST be grounded; unobserved claims `[INFERENCE]`.\n- Verification claims exactly match exercised work.\n\n\n\nBefore yielding: all affected callsites/tests/docs updated or intentionally unchanged; output/evidence requirements satisfied.\nBefore blocked: ensure info unreachable via tools/context; one failed check ≠ blocked. Finish reachable work; state exactly missing and tried.\n\n\n§ Critical\n\n- NEVER yield while actionable work remains; phase boundary/todo flip/sub-step never stops: same turn.\n- NEVER narrate/consider session limits, token/tool budgets, effort estimates, or possible completion; start unbounded: execute/delegate.\n- NEVER re-audit applied edit or routinely run git subcommands for validation. Tool results are verification.\n\n\n§ Role\nInvestigate the codebase rapidly. Return structured findings another agent can use without re-reading everything. `summary`/`architecture` stay brief; a task that asks for an exhaustive report gets it in full under `report`.\n\n\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\n\n\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\n\n\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\n\n\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\n\n§ Context\n# Goal\nHertz owns isolated hosted-relay replacement diagnosis; no live endpoint changes, no #304 implementation. Also resume #294 store-init mechanism planning only. Repo C:/Users/decid/Documents/projects/spt-core.\n# Constraints\nREAD ONLY. No builds, tests, formatters, probes, process execution, or edits. No agent/context file discovery. Skip all validation. Main owns fixture plan/execution. Return compressed evidence with exact file/range or git object citations; no peer reports.\n# Contract\nAll-0.69.0 tag16df0e41be04ca4614a792f7e70e4d1bdec60b24 distinct from mixed broker0.67.1 tag04e32c8c95cf09ddc2a44a51cd0233b0d13bdc64 plus caller/coordinator0.69.0. Report version compatibility mechanisms, not assumed field causality. Existing field findings at C:/Users/decid/AppData/Local/Temp/omp-slammie-rc/findings.txt (UTF16LE/legacy encoding) report old broker, new coordinator, prior controller accepted, listener replacement, now harness-only; no spanning classification snapshot or fresh PTY probe.\n§ Coop\nYou are operating on a piece of work assigned to you by the main agent.\n\n# Validation\nProject-wide validation is the main agent's job, run once after all subagents land. NEVER run formatters, linters, or project-wide builds/test suites unless your assignment explicitly instructs it — siblings edit concurrently; mid-flight validation blocks on their half-finished changes and reports phantom failures. Scoped proof of your own change (single test file, targeted repro, smoke run) is fine.\n# Peers\nYou can reach other live agents via the `hub` tool. Your id is `StoreInitNextMeasurement`. Currently visible peers:\n- `MixedRelayCompatibility` — scout (sub, running)\n- `Main` — main (main, running)\n2 parked peer(s) omitted.\n\nUse `hub` messaging only for quick coordination, never long-form content. Address peers by id or use `\"all\"` to broadcast.\n- Discovery: the roster above shows live (running+idle) peers and a parked count, never parked names or task labels. `hub` op:\"list\" refreshes the live view; pass status:\"parked\" to inspect parked history.\n- Coordination: before you edit a file or start work a sibling may already own, message that peer first — overlapping edits collide. Idle peers are not gone: messaging them wakes them.\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- Parked history: omitted from this roster. `hub` op:\"list\" status:\"parked\" lists ids; `send` to a known parked id revives it. `history://` and `agent://` stay readable.\n\n§ Completion\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 `data`.\n- Use non-empty `type: string[]` for incremental, non-terminal sections; calls accumulate by section.\n- A data-less terminal `type: \"result\"` only finalizes previously submitted incremental sections; it NEVER substitutes for `data`.\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 `data`.\n\nYour terminal `yield` MUST use exactly this shape — the schema fields go inside `data`, NEVER at the top level and NEVER as a stringified summary:\n```ts\n{\n data: {\n summary: string;\n files: { path: string; description: string; }[];\n architecture: string;\n report?: string;\n };\n}\n```\n\nGiving up is a last resort. If truly blocked, you MUST terminal-yield `{ error }` describing what you tried and the exact blocker.\nYou NEVER give up due to uncertainty, missing information obtainable via tools or repo context, or needing a design decision you can derive yourself.\n\nYou MUST keep going until this ticket is closed. This matters.\n\nPROJECT\n\n\n- OS: win32 10.0.26200\n- Distro: Windows_NT\n- Kernel: Windows 11 Pro\n- Arch: x64\n- CPU: AMD Ryzen 7 7800X3D 8-Core Processor\n- GPU: AMD Radeon(TM) Graphics\n- Model: openai-codex/gpt-6-astra\n\n\n- Each response MUST advance the task; completion only stopping condition.\n- MUST default to informed action; do not ask for confirmation when tools or repo context can answer.\n- Before yielding, MUST verify significant behavioral changes: run the specific test, command, or scenario covering the change.\n","task":"Complete assignment thoroughly:\n\n# Target\nRetained #294 specimens: .spt/preserved/deployah-294-armB-20260910/todlando-paired-stages.json and associated summary artifacts; source ContextStore::open_or_init_in and its child process launching path.

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 is the cause, then will make the bug disappear / 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.

Its clock is process_instant_since_diag_enable, not a cross-process wall clock (B2/events.jsonl:60-87).\n- poll.enter 38,092,898µs; requester.thread.enter 38,093,029µs; store_init.enter 38,093,068µs; store_init.exit 47,223,583µs. The measured store bracket is 9,130,515µs. The 131µs poll-entry→thread-entry gap is not a measured thread-creation duration: there is no spawn boundary in these retained events.\n- poll.expiry at 48,257,958µs: 400/400, reported poll duration 10,165,050µs. Four tip brackets total 2,211,485µs and straddle expiry; do not divide their entire duration by the expired window.\n- send-submission entry at 49,449,798µs is 1,191,840µs after expiry. Correlated inbound registration follows by 764µs; decoded sync_id is pull-2. This excludes a post-submission visibility delay as the reason for THIS acceptance expiry, without measuring a wire-write boundary or classifying other reds.\n- B1/B2/B3 store brackets are 1.869609/9.130515/5.739629s. First-sample carried-in cohorts are 0/6/12—not total concurrent populations or an exhaustive leak census. Acceptance-window overlap and resource contention remain unverified. B3 passing with more carried residue excludes nothing (paired JSON:1-10; ARM-B-REPORT.md:128-154).\n- Unknown inside B2’s store bracket: actual init branch/attempt count, each child’s creation/runtime, retry sleeps, parent/child scheduling, filesystem service and blocking, output-drain/join latency. No filesystem/AV/contention attribution follows. IR96/97 stay cause-unclassified; no causal filing or release change.\n\n## Source seam and why another aggregate timer is insufficient\nWorking-tree ContextStore::open_or_init_in delegates through seed_git_dir to BranchStore. BranchStore checks HEAD; absent HEAD triggers create_dir_all, git init --bare (up to 20 attempts with 10×(attempt+1)ms backoffs), required core.autocrlf config (read-before-write; up to 15 attempts with 15×(attempt+1)ms backoffs), and best-effort relative-path config. Existing HEAD skips that initialization. None of these branches/attempts is exposed by the retained store bracket (branchstore.rs:62-134,673-705).\nrun_git builds Command(\"git\"), calls spawn, creates stdout/stderr readers, then starts its timeout clock and loops try_wait with 10ms sleeps before joining readers (gitrun.rs:85-171). Thus run_git wall time is not Git execution time; spawn-return→status-observed includes child execution and parent scheduling/polling, while reader joins may extend after observed exit. The 30s timeout starts AFTER spawn/reader setup and does not encompass subsequent joins. Spawn counters count successful creation, not elapsed time or overlap.\n\n## One isolated preparatory measurement — proposed only\nMain owns fixture/execution. Use one disposable, uniquely owned root and one requester-style worker calling the REAL ContextStore::open_or_init_in once on an absent .seed.git. No broker, endpoint, suite, synthetic load or release artifact changes. Record exact diagnostic build identity, resolved Git image/version, root and environment; this is an instrumentation-readiness specimen, not a B2 reproduction or performance baseline. Do not clear global caches or change retry/timeout/pipe semantics.\n\nTemporary opt-in instrumentation, scoped by run/root/store-call ID:\n1. Worker spawn-call entry/return, worker first instruction, store entry/exit, with parent/worker TIDs. These distinguish caller creation API latency from first observed worker execution; they overlap and must not be summed blindly.\n2. Bracket every HEAD.exists and create_dir_all call, recording result; label filesystem API wall duration, not disk service time. Record each init/config command purpose, attempt number, exit/error/retry decision, and every backoff sleep request/wake (requested versus observed duration).\n3. In run_git, record entry, spawn-call entry, spawn return/error with child PID, reader creation and reader entry/EOF, each try_wait entry/return/status, each poll-sleep request/wake, status-observed, each reader join entry/return, and final return/error. Preserve outcomes even on failures. Fixed-size buffered records flushed outside the measured span avoid synchronous console/file logging on the critical path.\n4. In the SAME specimen, capture an OS trace providing process/thread start/exit, image identity, context switches/ReadyThread and correlated filesystem/I/O activity for this owned parent/child tree. This requires a recorder capability/privilege positive control; the previous WMI lifecycle subscription failed before its control (ARM-B-REPORT.md:7-13). Do not assume it is now usable or replace missing lifecycle data with presence samples. Add child-side Git Trace2 start/exit and available command/region records, with explicit clock correlation to parent/OS timestamps; Git start/exit still includes blocking/descheduling, not pure CPU work.\n\nExact interpretation: spawn-call bracket = parent creation-API wall time. OS child start→Git first marker = child startup bracket. Git markers delimit instrumented Git work; OS scheduled-running intervals distinguish CPU execution from ready-but-not-running intervals and blocked intervals. Correlated filesystem events expose operations inside parent/Git brackets; API wall time alone does not prove storage latency. OS child exit→first parent status observation isolates exit-observation lag, and EOF/join boundaries expose drainage/reader scheduling tails. Child execution can start before spawn returns; filesystem and scheduling classifications are nested/overlapping dimensions, not additive independent totals. Uninstrumented gaps retain an explicit unclassified label.\n\n## Acceptance gate and cleanup conditions\n- Pass preparation only if one store call reconciles to its complete command/attempt tree, each child joins by PID + creation identity/image, all relevant begin/end/error records survive, and process/CPU/filesystem/Git timelines correlate within a declared measured clock uncertainty. Record trace loss/overflow and unresolved intervals; do not silently allocate residual wall time to Git or scheduling.\n- Demonstrate actual fresh initialization took the intended branch. Capture init, config read/write as actually taken, and optional config result; do not assume a fixed successful-child count. No induced retry is required for this single preparation.\n- Missing scheduler/filesystem/child markers or denied tracing means preparation is INCOMPLETE for mechanism separation: keep the narrower evidence, name the missing layer, and do not proceed to a loaded run as though that layer were measured.

BranchStore checks HEAD; absent HEAD triggers create_dir_all, git init --bare (up to 20 attempts with 10×(attempt+1)ms backoffs), required core.autocrlf config (read-before-write; up to 15 attempts with 15×(attempt+1)ms backoffs), and best-effort relative-path config. Existing HEAD skips that initialization. None of these branches/attempts is exposed by the retained store bracket (branchstore.rs:62-134,673-705).\\nrun_git builds Command(\\\"git\\\"), calls spawn, creates stdout/stderr readers, then starts its timeout clock and loops try_wait with 10ms sleeps before joining readers (gitrun.rs:85-171). Thus run_git wall time is not Git execution time; spawn-return→status-observed includes child execution and parent scheduling/polling, while reader joins may extend after observed exit. The 30s timeout starts AFTER spawn/reader setup and does not encompass subsequent joins. Spawn counters count successful creation, not elapsed time or overlap.\\n\\n## One isolated preparatory measurement — proposed only\\nMain owns fixture/execution. Use one disposable, uniquely owned root and one requester-style worker calling the REAL ContextStore::open_or_init_in once on an absent .seed.git. No broker, endpoint, suite, synthetic load or release artifact changes. Record exact diagnostic build identity, resolved Git image/version, root and environment; this is an instrumentation-readiness specimen, not a B2 reproduction or performance baseline. Do not clear global caches or change retry/timeout/pipe semantics.\\n\\nTemporary opt-in instrumentation, scoped by run/root/store-call ID:\\n1. Worker spawn-call entry/return, worker first instruction, store entry/exit, with parent/worker TIDs. These distinguish caller creation API latency from first observed worker execution; they overlap and must not be summed blindly.\\n2. Bracket every HEAD.exists and create_dir_all call, recording result; label filesystem API wall duration, not disk service time. Record each init/config command purpose, attempt number, exit/error/retry decision, and every backoff sleep request/wake (requested versus observed duration).\\n3. In run_git, record entry, spawn-call entry, spawn return/error with child PID, reader creation and reader entry/EOF, each try_wait entry/return/status, each poll-sleep request/wake, status-observed, each reader join entry/return, and final return/error. Preserve outcomes even on failures. Fixed-size buffered records flushed outside the measured span avoid synchronous console/file logging on the critical path.\\n4. In the SAME specimen, capture an OS trace providing process/thread start/exit, image identity, context switches/ReadyThread and correlated filesystem/I/O activity for this owned parent/child tree. This requires a recorder capability/privilege positive control; the previous WMI lifecycle subscription failed before its control (ARM-B-REPORT.md:7-13). Do not assume it is now usable or replace missing lifecycle data with presence samples. Add child-side Git Trace2 start/exit and available command/region records, with explicit clock correlation to parent/OS timestamps; Git start/exit still includes blocking/descheduling, not pure CPU work.\\n\\nExact interpretation: spawn-call bracket = parent creation-API wall time. OS child start→Git first marker = child startup bracket. Git markers delimit instrumented Git work; OS scheduled-running intervals distinguish CPU execution from ready-but-not-running intervals and blocked intervals. Correlated filesystem events expose operations inside parent/Git brackets; API wall time alone does not prove storage latency. OS child exit→first parent status observation isolates exit-observation lag, and EOF/join boundaries expose drainage/reader scheduling tails. Child execution can start before spawn returns; filesystem and scheduling classifications are nested/overlapping dimensions, not additive independent totals. Uninstrumented gaps retain an explicit unclassified label.\\n\\n## Acceptance gate and cleanup conditions\\n- Pass preparation only if one store call reconciles to its complete command/attempt tree, each child joins by PID + creation identity/image, all relevant begin/end/error records survive, and process/CPU/filesystem/Git timelines correlate within a declared measured clock uncertainty.
