chore(review): track issue 213 STATUS timing integration

Linked issue

Refs #213 — approved issue. This does not close it or claim the initiating timeout is fixed.

Verification limits

• Full-suite validation was explicitly deferred after the earlier run was interrupted; its nontermination cause remains unknown. The provider-contract/runtime-harness stages did not complete in that invocation.

• POSIX execution was unavailable on the Windows host; POSIX branches were inspected, not executed.

• Native assessment was unavailable due to undeclared untracked scope. No native review approval is claimed and no real STATUS/retry was run for publication.

• Original source verification used baseline 9808b6ef, 52 commits behind main at publication. The tracker incorporates main 42653f72db9f8eb082035870682711209b0f48ef at head 75118e8a7fcf8f11046044e28213efca7132512c. Its resulting CI passed; independent verification confirmed provenance, candidate/CI tree identity, public scope, and eight successful checks, but its Windows log/count read was unavailable.

• Integration update accepted with the disclosed independent-proof limitation. No merge to main is authorized; no protected size-exception label is requested.

• Historical head 823fef4297fcb2d8b5e9f5f408748c0fc24c3279: all eight executable checks passed after the single authorized Windows rerun (run https://github.com/Gentleman-Programming/gentle-shell/actions/runs/37846752589, attempt 2). Installer: 251 pass, 0 fail, 54 platform skips; mandatory native Windows cases: 14 pass, 0 fail, 0 skips. That run checked out merge 41210ef5 against base f266ea13, not the later main snapshot.

• Updated head 75118e8a7fcf8f11046044e28213efca7132512c has verified parents 823fef42 and main 42653f72. New CI https://github.com/Gentleman-Programming/gentle-shell/actions/runs/37898242644 (attempt 1) completed SUCCESS. All eight executable checks passed for the updated head. Windows installer: 274 pass, 0 fail, 54 platform skips; mandatory native Windows cases: 15 pass, 0 fail, 0 skips. The Windows checkout log and Git parents prove merge 1148a8282e1e9eca6e32cd17a993d2d9ca9c9fae combines main 42653f72 with updated head 75118e8a. CodeRabbit is not used as a required acceptance gate; no approval is claimed.

• Independent post-update verification stopped without retry when its Windows-log filtering command could not run because Python was unavailable (exit 49). The Windows checkout and 274/0/54 installer counts plus 15/0/0 native counts were verified by the parent, not independently repeated. This is an independent-proof limitation, not a CI failure; the user explicitly accepted this limitation and closed acceptance of the integration update. This disposition does not turn the partial verifier result into PASS or authorize a merge to main.

Summary

Integration tracker ready for review. Children #1951 (diagnostics) and #1953 (portable test fixtures) are integrated; their committed provenance has been independently verified. The feature branch has now been updated with main 42653f72. CI for the updated head passed against main 42653f72; independent verification confirmed provenance, candidate/CI tree identity, public scope, and eight successful checks. The user accepted the disclosed unavailable independent Windows log/count read and closed acceptance of this integration update. No merge to main is authorized.

Changes

Path	Change
odd/tasks/status-timing-publication.md	Scope, evidence, work units and chain plan
#1951	Opt-in, session-only STATUS timing diagnostics, integration, generated runtime, tests and docs
#1953	Windows preference/PATH and launcher absolute-path test fixtures

Test plan

The initial plan was checked with git diff --cached --check. Both children are now integrated; the scoped evidence below describes their verification, not successful combined acceptance. The diagnostic child has 64/64 focused checks and independent 2/2 PASS; the fixture child has 4/4 focal and 219/219 regression PASS, independently repeated. Typecheck: 186 baseline diagnostics, no regressions. These are scoped results, not full-suite acceptance.

Contributor checklist

• Approved issue linked with the human-selected nonclosing reference
• Conventional work-unit commits; tests/docs remain with behavior
• Incident data excluded from commits
• Children feat(review): add opt-in session STATUS timing diagnostics #1951 and test(launcher): make Windows fixtures portable #1953 integrated into the tracker only
• CI green for updated head 75118e8a7fcf8f11046044e28213efca7132512c (run 37898242644, attempt 1)
• Integration update accepted for main snapshot 42653f72 and head 75118e8a with the user-approved independent Windows log/count limitation (not an independent PASS or merge authorization)

Chain Context

• Chain: issue-213-status-timing / feature-branch-chain
• Position: integrated tracker; update accepted with documented proof limitation; merge to main not authorized
• Base: main
• Starts at: validated baseline 9808b6ef
• Ends with: reviewed diagnostics and portable test fixtures after child integration
• Review budget: initial tracker 25 changed lines / 400; diagnostic child is necessarily oversized with tests/docs/runtime kept together
• Excludes: native authority recovery fixes, automatic STATUS/retries, global-suite fixes and merge

Separate Windows diagnosis

The frozen installer file at 41210ef5 fast-failed under Node 24.21.0 with worker exit 0xC0000409 in isolated run https://github.com/Gentleman-Programming/gentle-shell/actions/runs/37865560800. One Node 24.14.0 control, with the same source and recorded Windows image revision, completed with 47 pass, 0 fail and 1 Linux-only skip (all 14 native Windows cases passed): https://github.com/Gentleman-Programming/gentle-shell/actions/runs/37867770840.

The separate minimal overflow reproducer was built and executed once: https://github.com/Gentleman-Programming/gentle-shell/actions/runs/37874407946 (1 pass, 0 fail, 0 skips; ENOBUFS without a crash). Later post-spawn diagnostics and the original Windows job rerun did not reproduce the crash. The cause remains unknown: successful reruns are not a demonstrated repair. Diagnosis remains on separate branches; ProcDump is paused and is not an acceptance requirement. No production correction, normal-CI pin/downgrade, new diagnostic execution, or merge to main is included in this update.

Summary by CodeRabbit

• New Features
  • Added opt-in, session-only timing diagnostics for the next separately authorized STATUS-bearing tool call. Use /gentle:status-timing to enable, view, or clear diagnostics.

Merge Risk: 🔵 Low · up to 75118

The opt-in diagnostics can capture ABANDON’s pre-confirmation status read instead of the next authorized call. This affects timing data only, not review authorization or results, so the merge risk is low.

Thorough work on this tracker @dnlrsls.

Architecture feedback

The telemetry implementation in lib/status-timing-diagnostics.ts is remarkably clean:

• AsyncLocalStorage scoping: Using hostScope and nativeScope cleanly threads the timing samples across async phases without polluting native function signatures or passing context bags around.
• Fail-safe isolation: Wrapping collection in safely() guarantees that diagnostic probes never interfere with or fail the underlying STATUS resolution.
• Bounded privacy: Capping the sample buffers and allowlisting normalized failure codes protects telemetry from unbounded memory growth and sensitive data leakage.

Windows CI observation

Your isolation of the installer (windows-latest) failure to Node 24.21.0's worker crash (0xC0000409 STATUS_STACK_BUFFER_OVERRUN) is spot on. The clean 47/47 run on Node 24.14.0 confirms this is an environmental regression in the upstream Windows Node 24.21.0 runner image rather than an issue in the timing or fixture code.

Keeping this tracker unmerged while upstream CI settles is the right call. The diagnostic core itself is sound and ready.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not consume the timing arm on ABANDON’s pre-confirmation STATUS read.

gentle_review is wrapped by statusTiming.tool(...), so ABANDON runs inside the observer. ABANDON then calls nativeReviewCli.reviewStatus(...) before context.ui.confirm(...). observeNativeStatus claims the arm before running STATUS. The authorized recheck, or the next authorized STATUS call, is therefore not captured.

Exclude only the pre-confirmation inventory read from timing observation. Keep the post-confirmation recheck observable. The runtime diagnostic counterpart has the same claim-before-run behavior.
