Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\".\n- codebase-design: Shared vocabulary for designing deep modules. Use when the user wants to design or improve a module's interface, find deepening opportunities, decide where a seam goes, make code more testable or AI-navigable, or when another skill needs the deep-module vocabulary.\n- diagnose: Disciplined diagnosis loop for hard bugs and performance regressions. 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- diagnosing-bugs: Diagnosis loop for hard bugs and performance regressions. Use when the user says \"diagnose\"/\"debug this\", or reports something broken/throwing/failing/slow.\n- domain-modeling: Build and sharpen a project's domain model. Use when the user wants to pin down domain terminology or a ubiquitous language, record an architectural decision, or when another skill needs to maintain the domain model.\n- find-skills: Helps users discover and install agent skills when they ask questions like \"how do I do X\", \"find a skill for X\", \"is there a skill that can...\", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.\n- git-guardrails-claude-code: Set up Claude Code hooks to block dangerous git commands (push, reset --hard, clean, branch -D, etc.) before they execute. Use when user wants to prevent destructive git operations, add git safety hooks, or block git push/reset in Claude Code.\n- grilling: Grill the user relentlessly about a plan, decision, or idea. Use when the user wants to stress-test their thinking, or uses any 'grill' trigger phrases.\n- gstack: Fast headless browser for QA testing and site dogfooding. Navigate pages, interact with\nelements, verify state, diff before/after, take annotated screenshots, test responsive\nlayouts, forms, uploads, dialogs, and capture bug evidence. Use when asked to open or\ntest a site, verify a deployment, dogfood a user flow, or file a bug with screenshots. (gstack)\n\n- migrate-to-shoehorn: Migrate test files from `as` type assertions to @total-typescript/shoehorn. Use when user mentions shoehorn, wants to replace `as` in tests, or needs partial test data.\n- mux-send: Send keystrokes to a psmux terminal session. Use when the user says \"send to\",\n\"type in\", \"send keys to\", \"mux send\", or wants to send input to another terminal\nsession by name.\n\n- open-gstack-browser: Launch GStack Browser — AI-controlled Chromium with the sidebar extension baked in.\nOpens a visible browser window where you can watch every action in real time.\nThe sidebar shows a live activity feed and chat. Anti-bot stealth built in.\nUse when asked to \"open gstack browser\", \"launch browser\", \"connect chrome\",\n\"open chrome\", \"real browser\", \"launch chrome\", \"side panel\", or \"control my browser\".\n\n- propose-issue: Challenge an issue statement before fixing it. Probes scope, root cause, and assumptions\nthrough interactive questioning grounded in the codebase. 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). Even if the user doesn't say \"screenshot\" explicitly, use this skill if they want to see, capture, read, or annotate anything currently displayed on their screen.\n\n- setup-pre-commit: Set up Husky pre-commit hooks with lint-staged (Prettier), type checking, and tests in the current repo. Use when user wants to add pre-commit hooks, set up Husky, configure lint-staged, or add commit-time formatting/typechecking/testing.\n- spt-endpoint: Hosts an adapterless SPT endpoint perch inside Oh My Pi and reliably surfaces incoming messages through harness background-job completion. 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- tdd: Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions \"red-green-refactor\", or wants integration tests.\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 Codex session history.

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. 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</skills>\n# Internal URLs\nMost FS/bash tools auto-resolve these to FS paths.\n- `skill://<name>`: instructions; `/<path>`: its file\n- `rule://<name>`: details\n- `agent://<id>`: output artifact; `/<child>`: nested-subagent output; otherwise `/<path>`: JSON field\n- `history://<id>`: 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://<id>`: content\n- `local://<name>.md`: plan artifacts/shared subagent content\n- `mcp://<uri>`: MCP resource\n- `issue://<N>` / `issue://<owner>/<repo>/<N>`: GitHub issue; bare: recent; `?state=open|closed|all&limit=&author=&label=`.\n- `pr://<N>` / `pr://<owner>/<repo>/<N>`: 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- Bash: `bash`\n- Edit: `edit`\n- Eval: `eval`\n- Glob: `glob`\n- Grep: `grep`\n- Task: `task`\n- Hub: `hub`\n- Web Search: `web_search`\n- Write: `write`\n- Submit Result: `yield`\n# xd:// Tool Devices\nWrite JSON args as `content` to `xd://<tool>` via `write`. Invalid args return schema in error → fix/retry.\n## ast_edit — AST Edit\n\nStructural AST-aware rewrites via ast-grep. Use for codemods where text replace is unsafe. Mixed-language paths are fine: each file is parsed in its own language, and a pattern only rewrites files it parses in.\n\n- Metavariables in `pat` (`$A`, `$$$ARGS`) substitute into `out`.\n- **Patterns match AST structure, not text.** `$NAME` = one node; `$_` = unbound; `$$$NAME` = zero-or-more.\n  - Use `$$$NAME`, NOT `$$NAME` (invalid). Names UPPERCASE, whole node — partial like `prefix$VAR` fails.\n- Same metavariable twice → MUST match identical code (`$A == $A` matches `x == x`, not `x == y`).\n- Rewrite patterns MUST parse as single AST node. Non-standalone → wrap: `class $_ { … }`.\n- TS: tolerate annotations — `async function $NAME($$$ARGS): $_ { $$$BODY }`. Delete with empty `out`: `{\"pat\":\"console.log($$$)\",\"out\":\"\"}`.\n- 1:1 substitution — no splitting/merging captures.\n- Matches are STAGED as a proposal, not applied: finalize by writing a one-sentence reason to `xd://resolve` (apply) or `xd://reject` (discard).\n- Parse issues → malformed rewrite, not clean no-op. For one-off text edits, prefer the Edit tool.\n\n### Schema\n```ts\ntype Args = {\n  /** rewrite ops */\n  ops: Array<{\n    /** ast pattern */\n    pat: string;\n    /** replacement template */\n    out: string;\n  }>;\n  /** files, directories, globs, or internal URLs to rewrite */\n  paths: string[];\n};\n```\nExecute by writing JSON to xd://ast_edit.\n\n## debug — Debug\n\nDebugger access.

For merely moving, paging, trimming fetchable bytes: tool.\n\n<critical>\n`write xd://report_issue`: automated QA. Any tool output inconsistent with described behavior for parameters → write plain `<tool>: <concise description>` to `xd://report_issue`. False positives fine.\n</critical>\n\n# Exploration\nNEVER open files hoping. AVOID unneeded files/sections.\n- Use `read` offset/limit, not whole-file reads.\n\n# AST\nSHOULD use syntax-aware tools before text hacks:\n\n- Codemods → `ast_edit`.\n\n# Delegation\nInline first. Fan out only when 2+ independent slices each cost more than a handful of your own calls, or the read set would flood context; decide after your own first `grep`/`read`, never before it.\n- NEVER open with a scout. Scope with `grep`/`read`/`glob` yourself; a scout is for a genuinely unmapped subsystem after inline scoping stalls.\n- NEVER delegate one slice. One subagent for one job, a slice you already have open, cleanup (comment trims, changelog lines, formatting, sub-30-line edits), or a direct question: do it yourself.\n- NEVER babysit. Spawn → keep working → read the result. Steering a lone agent through `hub` send/wait costs more than the work.\n## Delegation gates\n- **Own decomposition.** Before spawning: map request, independent slices, cross-slice formats/schemas/interfaces. Only user-enumerated 2+ self-contained runnable slices dispatch directly. NEVER outsource top-level plan; generic \"plan\"/\"design\" agent starts blank, knows less, adds round-trip/no parallelism. Slice-local design and requested competing plans/reviews allowed.\n- **Real concurrency.** Fan exactly to genuine decomposition, one `tasks[]` array. NEVER serialize concurrent slices, invent padding, or spawn one then idle.\n- **User intent.** Subagents lack conversation; retain interpretation/taste; each assignment gets all slice requirements.\n- **Cap:** At most 32 subagents concurrently; excess queues. `tasks[]` batch > 32 delays results: stay within cap.\n- **Dependencies only.** A before B only if B strictly needs A; shared prerequisite inline, then fan out. “Parallelize” = parallel execution of independent slices, not agents routing sequential work. Small missing piece: run parallel; B asks A via `hub`!\n\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    - **Web UI** → use `browser.open` to get a tab handle, its direct helpers for common actions, `tab.run` for custom JavaScript, and `tab.close` when done; visual confirmation is proof; no tests unless existing suite really breaks.\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<contract>\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</contract>\n\n<completeness>\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</completeness>\n\n<evidence-and-output>\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</evidence-and-output>\n\n<yielding>\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</yielding>\n\n§ Critical\n<critical>\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</critical>\n\n§ Role\nWorker agent: delegated tasks.\n\nTools: FULL access (edit, write, bash, grep, read, etc.); MUST use as needed to complete task.\nMUST hyperfocus assigned task; NEVER deviate.\n\n<directives>\n- MUST finish assigned work only; return minimum useful result; do not repeat filesystem writes.\n- SHOULD edit files, run commands, create files when task requires.\n- MUST concise; NEVER filler, repetition, tool transcripts. User cannot see you; result: notes for yourself.\n- SHOULD prefer narrow lookups (`grep`/`glob`), then read needed ranges only; ignore beyond current scope.\n- AVOID full-file reads unless necessary.\n- SHOULD prefer editing existing files over creating new files.\n- NEVER create documentation files (`*.md`) unless explicitly requested.\n- MUST follow assignment and instructions.\n- `task` delegation: select most specific `agent` type per spawn; general-purpose worker only if no listed specialist fits.\n</directives>\n\n§ Context\n# Goal\nImplement diagnostic-only #302 STEP1 in C:/Users/decid/Documents/projects/spt-core/.worktrees/302-net-worker-stamps based39241675. Binding driver at root .spt/preserved/302/STEP1-DRIVER.md; read whole document. No remedy, no worker-count/cache/dial changes; knob SPT_RC_HITCH_DIAG=1, unset inert. Main owns integration/new shared diag crate/runtime wiring/requirements/proof. Skip ALL builds/tests/formatters/linters during concurrent editing. No commits. Keep changed file ownership strict; no edits outside named tree.\n# Constraints\nUse REQ-RC-HITCH-BOUNDARY-STAMPS (Main will add manifest before edits). Native Windows. External debugger attach unauthorized. Do not change Cargo.lock/root Cargo.toml: report dependency requirements to Main. LSP references required before exported symbol changes; worktree may be unlinked. Read relevant existing patterns. No new docs except needed existing docs updates owned Main.\n# Contract\nMain creates crates/spt-net-diag: pub fn enabled()->bool; pub fn begin(base: &'static str, execution: &'static str, subnet: Option<&str>, step: Option<u64>, stage: Option<&'static str>)->Option<Span>; Span::finish(self,outcome:&'static str); Span::id(&self)->u64; Span::context(&self)->Context. Context Clone carries parent/subnet/step; pub fn current_context()->Option<Context>; pub fn scope<F:Future>(context:Option<Context>,future:F)->impl Future<Output=F::Output> (restores TLS on poll/drop). pub fn event(name:&'static str, extra:serde_json::Value) (call only inside enabled guard to avoid unset allocations). pub fn thread_id()->u32; pub fn mono_ms()->u64; pub fn wall_ms()->u64. begin uses current context for missing subnet/step and parent id; unset returns None without allocation. Span Drop ends cancelled; finish ok/error explicit. Main owns emitter and independent watchdog. Stack backend interface detailed task. No shared file edits without Main coordination.\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 `NetBoundaryHooks`. Currently visible peers:\n- `NetStackCapture` — task (sub, running)\n- `NativeDependencyHooks` — task (sub, running)\n- `Main` — main (main, running)\n24 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://<id>` and `agent://<id>` 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- 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.

This is a diagnostic contract, not the conditional remedy.\n4:\n5:## Execution and safety\n6:\n7:One-command capture after the authorized instrumented build is staged:\n8:\n9:```text\n10:python .spt/preserved/302/step1-field.py --host decid@enlyzeam --seconds 180 --out .spt/preserved/302/field-STEP1-<unique-run>\n11:```\n12:\n13:This wrapper performs steps1–3 below, preserves before/after log bytes and their hashes, verifies append-only continuity, and runs the analyzer locally. Its SSH script is compressed into a bounded EncodedCommand; no remote helper file or stdin-EOF dependency. Optional `--home`, `--binary` and `--pty` override explicit inputs. It does not stage the build. Logs over16MiB refuse rather than silently omit epoch/sequence evidence.\n14:\n15:1. Run `step1-collect.ps1` on ENLYZEAM via the already-authorized SSH route. It only launches `spt node status --json` with `SPT_RC_HITCH_DIAG=1`, explicit resident home and scrubbed inherited SPT/OWL/CLAUDE identity. It emits JSONL to stdout; redirect it on the collecting machine, not into resident configuration. Default 180 seconds, 1 Hz, 5-second per-query limit. Kill only the retained owned query-client handle on timeout. Record skipped schedules rather than issuing catch-up bursts.\n16:2. Read a bounded byte snapshot of `logs/daemon.stderr.log` before and after the window. Preserve source path, byte range, capture UTC and SHA256. A rotated/truncated log or changed broker is a separate epoch, never silently stitched. Do not restart, update, configure, attach a debugger to, or stop a resident. The staged instrumented binary owns its watchdog/stack collection; this driver only reads its output.\n17:3. Run `step1-analyze.py --samples <jsonl> --log <snapshot> --out <new-directory>`. Outputs: normalized samples, round alignment, boundary spans, stack captures, per-interval verdict JSONL and summary JSON. Existing output is refused.\n18:4. Keep the original 25ms canary and dial gauge unchanged. Keep the simultaneous real rc ACK/echo observer independent; accept optional `--pty <jsonl>` for its timestamped observations. Missing PTY evidence is explicitly `not_observed`, never a claim that canary stalls caused the user-visible hitch.\n19:\n20:Completion: legacy dry-run emits honest insufficient-evidence rows; instrumented evidence can discriminate the candidate using both workers, with the same thresholds. No permission escalation is part of this lane.\n21:\n22:## Thresholds fixed before the run\n23:\n24:| Quantity | Contract |\n25:|---|---|\n26:| Default window | 180s at 1 Hz; valid range 10–900s |\n27:| Status query | owned client deadline 5000ms; kill confirmation 2000ms |\n28:| Usable diagnostic sample | exit 0, no timeout/probe error, net enabled, nonnegative numeric age/dials, same broker epoch; outer query <=250ms and gauge query <=250ms for precise joins |\n29:| Sample cadence | no inter-sample gap >1500ms within one observed stale episode; gaps split episodes and invalidate complete-run coverage |\n30:| Stale canary | age >=1000ms (40 nominal ticks); severe >=2000ms |\n31:| Healthy recovery | next valid sample below1000ms; observation gives a recovery bound, not an exact recovery time |\n32:| Long synchronous boundary | >=250ms; short overlaps are reported but not sufficient mechanism evidence |\n33:| Meet association | round before a peak by 0–15000ms; report the actual bounds, never force the historical 5–10s expectation |\n34:| Clock alignment | wall-minus-monotonic offset spread <=100ms within an epoch; otherwise temporal verdict is insufficient |\n35:| Instrumentation heartbeat | independent of the net runtime, at least every1000ms; interval coverage rejects >1500ms gaps or dropped/missing sequence records |\n36:| Stack trigger | independent watchdog when original canary age >=1000ms; paired both-worker capture every500ms while stale, max capture span100ms; errors and perturbation measured |\n37:| Repeated stack evidence | two complete paired captures >=250ms apart in the stale support interval; no one-worker substitution |\n38:| Run coverage PASS | >=95% usable samples, duration >=170s for default180s, no cadence gap >1500ms, one broker epoch; all six boundary capabilities, complete sequence/heartbeat coverage and both-worker evidence for every stale interval |\n39:| Mechanism CONFIRMED | a long synchronous candidate boundary on a named net worker overlaps a stale interval, and repeated paired stacks account for BOTH workers in candidate synchronous boundaries (or both tied to the same such operation). Mere async bind overlap is not enough |\n40:| Mechanism FALSIFIED for interval | complete candidate-boundary coverage places all boundaries outside the stale support; OR repeated complete paired stacks show both workers idle; OR both show unrelated progress using increasing genuine per-worker counters |\n41:| Otherwise | INSUFFICIENT_EVIDENCE; overlaps may still be reported. Missing diagnostics, no stale episodes, unknown worker, async wait only, clock discontinuity, or open/unmatched spans never become a healthy/falsified result |\n42:\n43:A run may be `MIXED`: some episodes confirm while others falsify. One confirmed episode establishes occurrence, not that all hitches have the same cause. Legacy data is not subject to an invented completeness PASS.\n44:\n45:## Canary intervals and clocks\n46:\n47:Preserve the existing fields `sampled_at_ms`, `net_canary_age_ms`, `active_dial_tasks`, `query_elapsed_ms`, `broker_pid`, `broker_version`. `sampled_at_ms` is wall time; the existing canary age also uses epoch milliseconds. Derive each stale sample's supported interval as `[sampled_at_ms - age + 1000, sampled_at_ms]`. Group successive stale samples only when no usable healthy sample intervenes and spacing <=1500ms. Emit observed first/last/peak, union support bounds, recovery bound, left/right censoring, maximum age and every dial count. Invalid samples break rather than bridge episodes.\n48:\n49:Clock-join uncertainty includes the status query duration. Product stamps use a shared process-wide monotonic clock plus wall clock. Do not infer monotonic time from TOTP step: NTP can shift the ceremony clock. For v1, align stamps via their wall clocks only after checking wall-minus-monotonic stability. Carry original monotonic stamps and operation durations in every row. Do not merge process restarts using PID alone: structured records have a unique `run_id`.\n50:\n51:Conservative join: stack captures must fit inside the stale support after shrinking both ends by sample-query uncertainty. Boundary exclusion uses the support expanded by that uncertainty. Raw bounds remain in output; near-edge evidence cannot silently become a confident exclusion.\n52:\n53:## Structured stamp schema — producer contract\n54:\n55:One atomic log line per record:\n56:\n57:```text\n58:NET_DIAG_V1: {\"v\":1,\"event\":\"NET_IF_ENUM_BEGIN\",\"seq\":12,\"run_id\":\"unique-broker-start\",\"broker_pid\":48932,\"wall_ms\":1789526670000,\"mono_ms\":123456,\"runtime\":\"spt-broker-net\",\"tid\":111,\"op_id\":\"17\",\"parent_op_id\":\"9\",\"execution\":\"sync\",\"subnet\":\"SPT_DEV\",\"step\":59650889}\n59:```\n60:\n61:Common REQUIRED fields: `v=1`, `event`, contiguous process-wide `seq` (START is seq0), unique `run_id`, `broker_pid`, `wall_ms`, `mono_ms`. Milliseconds are integer values from one monotonic origin shared across the broker's threads. `seq` is assigned at emission; serialize the line so partial/interleaved JSON cannot look complete. The parser retains file line numbers and rejects contradictory duplicates/gaps. No synchronous stderr flush/lock is allowed to become an unmeasured new worker stall; expose dropped records and instrument emission overhead if applicable.\n62:\n63:### Epoch and coverage\n64:\n65:- `NET_DIAG_START`: adds `worker_tids` (exact two actual OS TIDs for the unchanged `spt-broker-net` runtime), `capabilities` (the six base names below), `canary_period_ms:25`, `dropped_records:0`. Capture/announce after both worker IDs are known, not guessed from thread names. An incomplete startup census is unsupported.\n66:- `NET_DIAG_HEARTBEAT`: adds `dropped_records` (cumulative, must remain0). Emit on an independent observer, not a stalled runtime task.\n67:- `NET_DIAG_END`: normal epoch end if available; includes `dropped_records`. Driver may use a continuing live epoch with START and heartbeat coverage through the end of the sampled interval.\n68:\n69:### Boundary names and scope\n70:\n71:Every BEGIN/END pair carries the same `op_id`, `runtime`, `execution`, `parent_op_id` (null if no parent), and the actual `tid` at each stamp. END also carries `outcome` (`ok`, `error`, `cancelled`). IDs are unique within run_id. Nesting must retain parent identity. Async tasks may migrate TIDs; synchronous boundaries may not. `runtime` is `spt-broker-net`, `blocking-pool`, or `other`; labels describe the actual execution context, not the caller's intention.\n72:\n73:| Base name, suffixed `_BEGIN` / `_END` | Exact boundary | execution |\n74:|---|---|---|\n75:| `NET_IF_ENUM` | actual synchronous interface enumeration / GetAdaptersAddresses, including retry loop | sync |\n76:| `NET_GATEWAY_LOOKUP` | portmapper ip_and_gateway/HomeRouter::new synchronous work before protocol futures | sync |\n77:| `NET_CANCEL_MIB` | actual CancelMibChangeNotify2 call, per registration; not merely wrapper Drop entry | sync |\n78:| `NET_MEET_BIND` | whole per-subnet bind_rendezvous / endpoint builder bind; include subnet, step | async |\n79:| `NET_MEET_RETIRE` | actual endpoint/task retirement lifetime; include subnet, step, and `stage` on both stamps (`abort-request`, `task-drop`, or `endpoint-drop`), label sync/async truthfully | sync or async |\n80:| `NET_NTP_REFRESH` | actual cache-miss NTP refresh, including mutex/DNS/socket work, NOT every cache-hit now_secs call | sync |\n81:\n82:Abort requested is not retirement complete. Instrument the actual destructor/OS call separately. An open span remains open and unbounded; never synthesize END when a handle is merely aborted. Boundary END duration is computed from mono_ms, not wall time. Off-runtime synchronous work is recorded but does not by itself explain both net workers starving.\n83:\n84:### Meet/family alignment\n85:\n86:Keep existing human lines. Also emit structured `NET_MEET_ROUND` (step, subnets array), `NET_FAMILY_GATE` and `PAIR_MEET_UP` (step, subnet, op_id of the bind). These use the common timestamp/epoch fields. Family gates are emitted AFTER family probing, just as today. Bind attribution must be carried through the task, not guessed from the last log line.\n87:\n88:Legacy 0.70.0 lines without timestamps are bounded by nearest surrounding wall_ms log lines and grouped by their actual PAIR_MEET_UP step. Such bounds are line-order evidence only: concurrent writers can interleave, so flag them approximate. Report unpaired NET_FAMILY_GATE lines; never assign each gate to a subnet by adjacency. Three subnets are an admission observation, not a parser constant.\n89:\n90:### Both-worker stack capture\n91:\n92:`NET_WORKERS_SNAPSHOT` common fields plus:\n93:\n94:```json\n95:{\"capture_id\":\"s3\",\"capture_begin_mono_ms\":123000,\"capture_end_mono_ms\":123030,\"trigger_canary_age_ms\":2030,\"workers\":[{\"tid\":111,\"activity\":\"boundary\",\"op_id\":\"17\",\"frames\":[\"ntdll!NtWaitForSingleObject\",\"iphlpapi!GetAdaptersAddresses\"],\"progress_counter\":null,\"error\":null},{\"tid\":222,\"activity\":\"boundary\",\"op_id\":\"18\",\"frames\":[\"iphlpapi!CancelMibChangeNotify2\"],\"progress_counter\":null,\"error\":null}]}\n96:```\n97:\n98:`workers` must cover both START TIDs exactly, with no error, real symbolized frames, capture duration<=100ms and trigger age>=1000ms. Include raw stack evidence in the frames (or additionally a retained raw artifact); unknown/unwind failure stays explicit. `activity` is `boundary`, `idle`, `unrelated`, or `unknown`:\n99:- boundary: op_id must match a synchronous active span on that worker; frames must contain the relevant boundary symbol, not just a generic wait. Async builder/probe frames alone are not blocked-worker proof.\n100:- idle: real Tokio worker/park or reactor-park frames; a generic Windows wait alone does not prove executor idle.\n101:- unrelated: nonempty real frames plus a genuine completed-work counter increasing between paired captures. If that counter is unavailable, use unknown; do not manufacture one from sample number or wall time.\n102:\n103:The independent watchdog captures while the original canary is stale; worker-cooperative callbacks that only run after recovery cannot establish an in-peak stack. No driver-triggered external debugger attach is authorized. Capture must record its own elapsed time so induced stalls are visible.\n104:\n105:## Optional PTY observation input\n106:\n107:JSONL rows: `wall_ms`, `route` (`local` or `remote`), `tag`, `sent_ms`, `ack_ms` (null if not yet observed), `state_confirmed` boolean. The driver reports correlations and RTT with a2000ms bound; no PTY input means the runtime discriminator is usable but user-visible causality remains unmeasured. Existing observer formats must be adapted explicitly rather than silently inferred.\n108:\n109:## Artifacts and command forms\n110:- `step1-field.py`: bounded SSH wrapper performing log-before → collector → log-after → append-only check → local analysis, retaining each receipt. Exit codes follow the analyzer unless capture fails.\n111:\n112:- `step1-collect.ps1`: read-only 1Hz collector, stdout JSONL; parameters `-Seconds`, `-HomePath`, `-Binary`, optional `-ReplaySamples` for local dry-run without launching any spt process.\n113:- `step1_rounds.py`: `parse_rounds(lines)` returns legacy/structured round evidence; `align_rounds(rounds, interval_start_ms, peak_ms)` returns bounded preceding associations.\n114:- `step1-analyze.py`: command above. Exit0 = fully discriminated field run; exit2 = valid analysis with insufficient evidence/coverage; exit1 = malformed input or execution failure. A supported mechanism result is not a product-fix PASS.\n115:\n116:## Verified dry-run receipts\n117:\n118:- `step1-dry-run-070-final/`: historical ENLYZEAM180 samples, all180 usable; 17 stale, 7 severe, maximum4912ms, dials0 throughout. Eleven threshold-defined stale intervals. All11 correctly emit `INSUFFICIENT_EVIDENCE` because0.70.0 supplies no boundary stamps or worker stacks; analyzer exit2.\n119:- Actual0.70.0 log snapshot: `enlyzeam-070-daemon-snapshot.log`, SHA256 `71191246be63369db00f4bc41b5e7c92515a6e15ace3a896616ba7140c90709a`. Each of the three largest peaks has a possible preceding three-subnet UP envelope and three family gates. Timing brackets are broad; two include slightly post-peak UP times. The parser does not turn the historical5–10s interpretation into exact data.\n120:- `step1-replay.jsonl`: all180 collector replay rows preserve every original measurement field exactly, exit0.\n121:- `step1-live-smoke-070.jsonl`: ten read-only live status queries on ENLYZEAM, same resident broker48932/version0.70.0; all clients exit0 with termination confirmed. No daemon lifecycle action.\n122:- `step1-field-smoke-070-v2/field-receipt.json`: complete wrapper smoke, ten-second collector exit0, before/after logs append-only, local analyzer exit2 as expected for short unsupported legacy evidence.\n123:- `step1-contract-verification.json`: synthetic protocol checks, NOT field mechanism evidence. Twelve discriminator cases and four round-uncertainty cases pass: both-worker synchronous overlap, outside peak, true Tokio idle, unrelated progressing work, async-only, missing worker, generic wait, open span, missing sequence, unknown stamp, clock jump, missing/reversed anchors and duplicate UP.\n124:\n125:Transport-attempt history: an uncompressed encoded script exceeded Windows argv length; a stdin-based wrapper later timed out. The final compressed-argv transport completed the full smoke. The abandoned stdin collector was our own PowerShell process, not a daemon; birth+parent+exact-command checks guarded its termination (`step1-owned-stdin-cleanup.json`). No resident daemon, config, adapter or lifecycle state was changed. Earlier failure artifacts remain preserved.\n126:\n127:Field verdict awaits the staged instrumented build.

No permission escalation is part of this lane.\n\n## Thresholds fixed before the run\n\n| Quantity | Contract |\n|---|---|\n| Default window | 180s at 1 Hz; valid range 10–900s |\n| Status query | owned client deadline 5000ms; kill confirmation 2000ms |\n| Usable diagnostic sample | exit 0, no timeout/probe error, net enabled, nonnegative numeric age/dials, same broker epoch; outer query <=250ms and gauge query <=250ms for precise joins |\n| Sample cadence | no inter-sample gap >1500ms within one observed stale episode; gaps split episodes and invalidate complete-run coverage |\n| Stale canary | age >=1000ms (40 nominal ticks); severe >=2000ms |\n| Healthy recovery | next valid sample below1000ms; observation gives a recovery bound, not an exact recovery time |\n| Long synchronous boundary | >=250ms; short overlaps are reported but not sufficient mechanism evidence |\n| Meet association | round before a peak by 0–15000ms; report the actual bounds, never force the historical 5–10s expectation |\n| Clock alignment | wall-minus-monotonic offset spread <=100ms within an epoch; otherwise temporal verdict is insufficient |\n| Instrumentation heartbeat | independent of the net runtime, at least every1000ms; interval coverage rejects >1500ms gaps or dropped/missing sequence records |\n| Stack trigger | independent watchdog when original canary age >=1000ms; paired both-worker capture every500ms while stale, max capture span100ms; errors and perturbation measured |\n| Repeated stack evidence | two complete paired captures >=250ms apart in the stale support interval; no one-worker substitution |\n| Run coverage PASS | >=95% usable samples, duration >=170s for default180s, no cadence gap >1500ms, one broker epoch; all six boundary capabilities, complete sequence/heartbeat coverage and both-worker evidence for every stale interval |\n| Mechanism CONFIRMED | a long synchronous candidate boundary on a named net worker overlaps a stale interval, and repeated paired stacks account for BOTH workers in candidate synchronous boundaries (or both tied to the same such operation). Mere async bind overlap is not enough |\n| Mechanism FALSIFIED for interval | complete candidate-boundary coverage places all boundaries outside the stale support; OR repeated complete paired stacks show both workers idle; OR both show unrelated progress using increasing genuine per-worker counters |\n| Otherwise | INSUFFICIENT_EVIDENCE; overlaps may still be reported. Missing diagnostics, no stale episodes, unknown worker, async wait only, clock discontinuity, or open/unmatched spans never become a healthy/falsified result |\n\nA run may be `MIXED`: some episodes confirm while others falsify. One confirmed episode establishes occurrence, not that all hitches have the same cause. Legacy data is not subject to an invented completeness PASS.\n\n## Canary intervals and clocks\n\nPreserve the existing fields `sampled_at_ms`, `net_canary_age_ms`, `active_dial_tasks`, `query_elapsed_ms`, `broker_pid`, `broker_version`. `sampled_at_ms` is wall time; the existing canary age also uses epoch milliseconds. Derive each stale sample's supported interval as `[sampled_at_ms - age + 1000, sampled_at_ms]`. Group successive stale samples only when no usable healthy sample intervenes and spacing <=1500ms. Emit observed first/last/peak, union support bounds, recovery bound, left/right censoring, maximum age and every dial count. Invalid samples break rather than bridge episodes.\n\nClock-join uncertainty includes the status query duration. Product stamps use a shared process-wide monotonic clock plus wall clock. Do not infer monotonic time from TOTP step: NTP can shift the ceremony clock. For v1, align stamps via their wall clocks only after checking wall-minus-monotonic stability. Carry original monotonic stamps and operation durations in every row. Do not merge process restarts using PID alone: structured records have a unique `run_id`.\n\nConservative join: stack captures must fit inside the stale support after shrinking both ends by sample-query uncertainty. Boundary exclusion uses the support expanded by that uncertainty. Raw bounds remain in output; near-edge evidence cannot silently become a confident exclusion.\n\n## Structured stamp schema — producer contract\n\nOne atomic log line per record:\n\n```text\nNET_DIAG_V1: {\"v\":1,\"event\":\"NET_IF_ENUM_BEGIN\",\"seq\":12,\"run_id\":\"unique-broker-start\",\"broker_pid\":48932,\"wall_ms\":1789526670000,\"mono_ms\":123456,\"runtime\":\"spt-broker-net\",\"tid\":111,\"op_id\":\"17\",\"parent_op_id\":\"9\",\"execution\":\"sync\",\"subnet\":\"SPT_DEV\",\"step\":59650889}\n```\n\nCommon REQUIRED fields: `v=1`, `event`, contiguous process-wide `seq` (START is seq0), unique `run_id`, `broker_pid`, `wall_ms`, `mono_ms`. Milliseconds are integer values from one monotonic origin shared across the broker's threads. `seq` is assigned at emission; serialize the line so partial/interleaved JSON cannot look complete. The parser retains file line numbers and rejects contradictory duplicates/gaps. No synchronous stderr flush/lock is allowed to become an unmeasured new worker stall; expose dropped records and instrument emission overhead if applicable.\n\n### Epoch and coverage\n\n- `NET_DIAG_START`: adds `worker_tids` (exact two actual OS TIDs for the unchanged `spt-broker-net` runtime), `capabilities` (the six base names below), `canary_period_ms:25`, `dropped_records:0`. Capture/announce after both worker IDs are known, not guessed from thread names. An incomplete startup census is unsupported.\n- `NET_DIAG_HEARTBEAT`: adds `dropped_records` (cumulative, must remain0). Emit on an independent observer, not a stalled runtime task.\n- `NET_DIAG_END`: normal epoch end if available; includes `dropped_records`. Driver may use a continuing live epoch with START and heartbeat coverage through the end of the sampled interval.\n\n### Boundary names and scope\n\nEvery BEGIN/END pair carries the same `op_id`, `runtime`, `execution`, `parent_op_id` (null if no parent), and the actual `tid` at each stamp. END also carries `outcome` (`ok`, `error`, `cancelled`). IDs are unique within run_id. Nesting must retain parent identity. Async tasks may migrate TIDs; synchronous boundaries may not. `runtime` is `spt-broker-net`, `blocking-pool`, or `other`; labels describe the actual execution context, not the caller's intention.\n\n| Base name, suffixed `_BEGIN` / `_END` | Exact boundary | execution |\n|---|---|---|\n| `NET_IF_ENUM` | actual synchronous interface enumeration / GetAdaptersAddresses, including retry loop | sync |\n| `NET_GATEWAY_LOOKUP` | portmapper ip_and_gateway/HomeRouter::new synchronous work before protocol futures | sync |\n| `NET_CANCEL_MIB` | actual CancelMibChangeNotify2 call, per registration; not merely wrapper Drop entry | sync |\n| `NET_MEET_BIND` | whole per-subnet bind_rendezvous / endpoint builder bind; include subnet, step | async |\n| `NET_MEET_RETIRE` | actual endpoint/task retirement lifetime; include subnet, step, and `stage` on both stamps (`abort-request`, `task-drop`, or `endpoint-drop`), label sync/async truthfully | sync or async |\n| `NET_NTP_REFRESH` | actual cache-miss NTP refresh, including mutex/DNS/socket work, NOT every cache-hit now_secs call | sync |\n\nAbort requested is not retirement complete. Instrument the actual destructor/OS call separately. An open span remains open and unbounded; never synthesize END when a handle is merely aborted. Boundary END duration is computed from mono_ms, not wall time. Off-runtime synchronous work is recorded but does not by itself explain both net workers starving.\n\n### Meet/family alignment\n\nKeep existing human lines. Also emit structured `NET_MEET_ROUND` (step, subnets array), `NET_FAMILY_GATE` and `PAIR_MEET_UP` (step, subnet, op_id of the bind). These use the common timestamp/epoch fields. Family gates are emitted AFTER family probing, just as today. Bind attribution must be carried through the task, not guessed from the last log line.\n\nLegacy 0.70.0 lines without timestamps are bounded by nearest surrounding wall_ms log lines and grouped by their actual PAIR_MEET_UP step. Such bounds are line-order evidence only: concurrent writers can interleave, so flag them approximate. Report unpaired NET_FAMILY_GATE lines; never assign each gate to a subnet by adjacency. Three subnets are an admission observation, not a parser constant.\n\n### Both-worker stack capture\n\n`NET_WORKERS_SNAPSHOT` common fields plus:\n\n```json\n{\"capture_id\":\"s3\",\"capture_begin_mono_ms\":123000,\"capture_end_mono_ms\":123030,\"trigger_canary_age_ms\":2030,\"workers\":[{\"tid\":111,\"activity\":\"boundary\",\"op_id\":\"17\",\"frames\":[\"ntdll!NtWaitForSingleObject\",\"iphlpapi!GetAdaptersAddresses\"],\"progress_counter\":null,\"error\":null},{\"tid\":222,\"activity\":\"boundary\",\"op_id\":\"18\",\"frames\":[\"iphlpapi!CancelMibChangeNotify2\"],\"progress_counter\":null,\"error\":null}]}\n```\n\n`workers` must cover both START TIDs exactly, with no error, real symbolized frames, capture duration<=100ms and trigger age>=1000ms. Include raw stack evidence in the frames (or additionally a retained raw artifact); unknown/unwind failure stays explicit. `activity` is `boundary`, `idle`, `unrelated`, or `unknown`:\n- boundary: op_id must match a synchronous active span on that worker; frames must contain the relevant boundary symbol, not just a generic wait. Async builder/probe frames alone are not blocked-worker proof.\n- idle: real Tokio worker/park or reactor-park frames; a generic Windows wait alone does not prove executor idle.\n- unrelated: nonempty real frames plus a genuine completed-work counter increasing between paired captures. If that counter is unavailable, use unknown; do not manufacture one from sample number or wall time.\n\nThe independent watchdog captures while the original canary is stale; worker-cooperative callbacks that only run after recovery cannot establish an in-peak stack. No driver-triggered external debugger attach is authorized. Capture must record its own elapsed time so induced stalls are visible.\n\n## Optional PTY observation input\n\nJSONL rows: `wall_ms`, `route` (`local` or `remote`), `tag`, `sent_ms`, `ack_ms` (null if not yet observed), `state_confirmed` boolean. The driver reports correlations and RTT with a2000ms bound; no PTY input means the runtime discriminator is usable but user-visible causality remains unmeasured. Existing observer formats must be adapted explicitly rather than silently inferred.\n\n## Artifacts and command forms\n- `step1-field.py`: bounded SSH wrapper performing log-before → collector → log-after → append-only check → local analysis, retaining each receipt. Exit codes follow the analyzer unless capture fails.\n\n- `step1-collect.ps1`: read-only 1Hz collector, stdout JSONL; parameters `-Seconds`, `-HomePath`, `-Binary`, optional `-ReplaySamples` for local dry-run without launching any spt process.\n- `step1_rounds.py`: `parse_rounds(lines)` returns legacy/structured round evidence; `align_rounds(rounds, interval_start_ms, peak_ms)` returns bounded preceding associations.\n- `step1-analyze.py`: command above. Exit0 = fully discriminated field run; exit2 = valid analysis with insufficient evidence/coverage; exit1 = malformed input or execution failure. A supported mechanism result is not a product-fix PASS.\n\n## Verified dry-run receipts\n\n- `step1-dry-run-070-final/`: historical ENLYZEAM180 samples, all180 usable; 17 stale, 7 severe, maximum4912ms, dials0 throughout. Eleven threshold-defined stale intervals. All11 correctly emit `INSUFFICIENT_EVIDENCE` because0.70.0 supplies no boundary stamps or worker stacks; analyzer exit2.\n- Actual0.70.0 log snapshot: `enlyzeam-070-daemon-snapshot.log`, SHA256 `71191246be63369db00f4bc41b5e7c92515a6e15ace3a896616ba7140c90709a`. Each of the three largest peaks has a possible preceding three-subnet UP envelope and three family gates. Timing brackets are broad; two include slightly post-peak UP times. The parser does not turn the historical5–10s interpretation into exact data.\n- `step1-replay.jsonl`: all180 collector replay rows preserve every original measurement field exactly, exit0.\n- `step1-live-smoke-070.jsonl`: ten read-only live status queries on ENLYZEAM, same resident broker48932/version0.70.0; all clients exit0 with termination confirmed. No daemon lifecycle action.\n- `step1-field-smoke-070-v2/field-receipt.json`: complete wrapper smoke, ten-second collector exit0, before/after logs append-only, local analyzer exit2 as expected for short unsupported legacy evidence.\n- `step1-contract-verification.json`: synthetic protocol checks, NOT field mechanism evidence. Twelve discriminator cases and four round-uncertainty cases pass: both-worker synchronous overlap, outside peak, true Tokio idle, unrelated progressing work, async-only, missing worker, generic wait, open span, missing sequence, unknown stamp, clock jump, missing/reversed anchors and duplicate UP.\n\nTransport-attempt history: an uncompressed encoded script exceeded Windows argv length; a stdin-based wrapper later timed out. The final compressed-argv transport completed the full smoke. The abandoned stdin collector was our own PowerShell process, not a daemon; birth+parent+exact-command checks guarded its termination (`step1-owned-stdin-cleanup.json`). No resident daemon, config, adapter or lifecycle state was changed. Earlier failure artifacts remain preserved.\n\nField verdict awaits the staged instrumented build. No synchronous boundary has yet been measured as the #302 culprit, and PTY causality is still unobserved in this lane.","startLine":1,"lineNumbers":[1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,126,127]},"fileSize":16090,"meta":{"source":{"type":"path","value":"C:/Users/decid/Documents/projects/spt-core/.spt/preserved/302/STEP1-DRIVER.md"}}},"isError":false,"timestamp":1789538710654}}
