A failed Windows ACL operation currently loses the execution detail needed to distinguish a spawn failure, a runner rejection, a caller watchdog, a pre-spawn deadline and a completed child result. Preserve a bounded diagnostic record through the existing sanitized error boundary.
The record contains fixed stage/step enums, finite timing/budget values, success/exit/timeout information and an allowlisted spawn error code. It excludes paths, account identities, arguments, raw errors and process output. Existing error codes, required-write refusal, retries, timeout memo and reap policy are retained.
The bearer-admission fixture also gains opt-in OPENCODEX_BEARER_STAGE_TRACE=1 timing for configuration save, startup, request, stop and capture close. It records both the whole-test and iteration clocks. Request tracing now covers the original body reader, including JSON parsing. Chat still rejects an unexpected 200 before draining its body. Whole-test finalization runs after normal cleanup unwinds, including assertion failures. Synchronous stages remain synchronous when tracing is off; no retry or timer is added.
Verification
URL type follow-up — 2517c7c85c515781c7ea3565e0c19ba8981b79c8
The two shared bearer trace helper parameters now accept string | URL, matching Bun Server.url and the existing post functions. This follow-up changes only type annotations in tests/codex-integration/bearer-admission-routed-provider.test.ts.
Pinned Bun 1.4.4 on Linux: bun test ./tests/codex-integration/bearer-admission-routed-provider.test.ts --test-name-pattern 'bearer stage tracer seam' passed 5 tests / 42 assertions, including the real local-server URL path.
bun run typecheck, bun run structure:check, bun run privacy:scan, git diff --check, and the size-ratchet suite (9 tests / 85 assertions) passed.
A separate TypeScript configuration that includes this test file removed exactly the reported URL-to-string error: 5 diagnostics before, 4 unchanged baseline diagnostics after, none added. The four remaining diagnostics concern Http2Stream.respond, two optional visionSidecar accesses and an account fixture label; this broader test-file check is not claimed as passing. The official source-only typecheck does pass.
The published tree 58fadc17251d8df330f3d0289aa7261e12241dce matches the locally verified file. Current-head Cross-platform CI and Catalog async contracts both completed successfully on this exact head. Policy-skipped native jobs are not native-platform acceptance evidence. Native Windows/macOS and the unchanged ACL suites were not rerun for these two type annotations.
Earlier diagnostic and trace validation
Previously validated head: c587dc3740eb3f1b45f723c64d854cc17dd134f4. The ACL implementation and its diagnostic suite are unchanged from 13d7abc2; this follow-up changes the bearer trace fixture. Local validation used Windows and pinned Bun 1.4.4.
Restoring the baseline helper produced 12 semantic failures for missing diagnostics. A cleanup gap in the new watchdog test was then repaired with finally; its baseline case still fails meaningfully with no teardown timeout.
New and existing ACL suites: 186 passed, including mandatory atomic-write refusal. After the test-only cleanup repair, the final diagnostic file passed 13 cases / 50 assertions. The unchanged suites were not repeated.
Current shared-flow trace regressions: 5 passed / 42 assertions. A final test-only body-entry guard was rechecked separately (1 passed / 6 assertions). Controlled old-behavior variants produced two header-only trace failures and one success-only finalization failure, with exact candidate restoration and no cleanup hang.
Actual local Responses and Chat bearer fixtures: each 11-iteration loop passed in 18.2s / 17.9s on the follow-up, retaining the existing 30-second test budget.
Commands had an external 55-second bound, native exit/EOF and owned-process cleanup checks. Source hashes were checked before and after execution; no owned process or sandbox remained.
The original intermittent CI ACL failure did not recur in these local fixture runs. This PR improves diagnosis; it does not claim to fix that incident or infer an external process kill from timing alone. Injected-runner late-reap tests establish the tracking contract, not real OS-child termination. Retained output is bounded; complete retained trace records were checked separately from truncated output.
No installed runtime, account, certificate, permissions policy or global configuration was changed. The prior 13d7abc2 head passed Cross-platform CI and Catalog async contracts. The earlier c587dc3 head passed Cross-platform CI and Catalog async contracts. The two earlier trace follow-up review threads are resolved. Hosted Windows and macOS lanes were skipped; native Windows validation above was local. Explicit security review remains required before merge.

Scope is limited to diagnostics, focused fixtures and their owning contract.

Summary by CodeRabbit
New Features
Windows ACL hardening failures now include bounded diagnostics identifying the failed operation, failure stage, timing, and result. Sensitive paths, arguments, and process output are excluded.
Bug Fixes
ACL failure details are retained across synchronous and asynchronous operations, including timeouts and startup failures, while preserving existing error behavior. Required ACL hardening failures prevent atomic-file publication, and diagnostics distinguish pre-startup failures from child-process results.
Distinguish spawn, runner rejection, caller watchdog and child-result evidence without exposing paths, principals or command output. Keep existing hardening and reap behavior, and add opt-in stage timing for the bearer-admission fixture.
Windows ACL failures now carry validated, bounded diagnostics in sanitized errors. Windows tests and test-layout mappings cover those diagnostics. The bearer-admission integration test adds opt-in stage tracing for indexed cases.
ACL runner results distinguish spawn failures, runner rejections, and watchdog timeouts. The module defines allowed ACL steps and failure stages.
Per-run diagnostics and sanitized errors src/lib/windows-secret-acl.ts
Sync and async ACL sequences record failure stage, elapsed time, and budget. Sanitized errors receive diagnostics only after validation and allowlist checks succeed.
Diagnostics validation and test mapping tests/windows/windows-secret-acl-diagnostics.test.ts, tests/fixtures/test-layout-expected.json, scripts/test-layout/layout.json, structure/ops/service-and-sidecars.md
Tests cover sync and async failure paths, diagnostic sanitization, and atomic-write behavior. The Windows test mappings and operations documentation include the diagnostics test and record fields.
Bearer-admission test tracing
Layer / File(s)
Summary
Trace wrappers and request stages tests/codex-integration/bearer-admission-routed-provider.test.ts
Opt-in tracing records elapsed-time events. The request stage includes response-body reading, and Chat checks for a non-200 status before reading the body.
Indexed bearer matrix and trace tests tests/codex-integration/bearer-admission-routed-provider.test.ts
The indexed matrix records completion for each iteration, including failures. Tests check event order, disabled tracing, request timing, and cleanup.

- Around line 942-945: Update the request callback passed to tracedBearerStage
so it includes both the HTTP call and response-body read. In the bearer
admission test’s Chat and Responses branches, await the response and consume its
body with the existing assertions inside the callback, so the traced request
stage remains active until the workflow completes.
- Around line 952-961: Move the `trace?.finish()` call into a `finally` block
surrounding the cases loop so the whole-test trace records its terminal
`test_end` and final elapsed value even when an iteration fails. Keep the
existing per-iteration cleanup and `iteration?.finish()` behavior unchanged.

Copy the value that passed validation.
If a runner throws an error with a changing aclFailure.step getter, the first two reads at Line 1189 can return "/grant:r", while the read at Line 1207 returns a private path. A required harden then copies that path into the public aclFailure record. The same repeated-read pattern affects the other validated fields. Read each field once into a local value, then validate and copy only those local values. Add a regression test with a changing getter. The required-error path passes runner errors through this sanitizer. (raw.githubusercontent.com)

Maintainer dev integration (L5 lane), per MAINTAINERS.md.
Decision: squash-merge at exact head a32f7a1170b8407eaec1bce3bd79278fc61519cd.
Security review: independent round 1 PASS (0 blocking, 0 non-blocking) at 2517c7c8. The head then moved only by an origin/dev update-branch merge, which brought in fix(claude): drain parent ACL flights before intercept secret writes #7777's ACL barrier. A delta security round at a32f7a11 also PASSED with 0 blocking findings: diagnostics, sanitization, barrier timeout ownership, refusal and timeout memo all integrate correctly. In that round windows-secret-acl-diagnostics plus claude-intercept-acl-barrier passed 43/0.
PR CI at the exact head: Cross-platform CI 40509141113 success, Catalog async contracts 40509141118 success, PR hygiene and target checks success.
lane=all 40513796719 at the exact head: every macOS, Ubuntu, desktop and Windows job succeeded except windows 9/9 (and the ci aggregate that it fails). That shard failed in cli-start-journal-order > "a healthy proxy owner preserves the journal for both start and ensure". The same case failed on dev itself in lane=all 40434080650 (1de2b71b), and this PR touches none of the start, liveness or journal code. The failure is tracked in [Bug]: start can recover the Codex journal under a live owner when the first liveness probe misses it #7827; it was investigated, not rerun.
Current with dev962546af: the 4 newer dev commits overlap only the union files scripts/test-layout/layout.json and tests/fixtures/test-layout-expected.json. On the locally merged tree (git merge-tree, no conflicts), test-layout, test-layout-tooling, file-size ratchet and the diagnostics test passed 51/0, and tsc --noEmit and structure:check exited 0.
Resolve tests/codex-integration/bearer-admission-routed-provider.test.ts to dev's traced admission matrix from #7773; this PR's earlier fixture restructure of the same matrix is superseded.
