Reviewed against main at 5ac169f. All five of #274's acceptance criteria are genuinely enforced by this file — I mutation-tested each one rather than reading it, since #274 itself says a test that does not fail on the reintroduced defect is decoration.
| Mutation | Result |
|---|---|
Rogue cosign sign step added to publish.yml |
caught — job "tag" step "Rogue signer" invokes cosign sign |
Rogue actions/attest-build-provenance added to release.yml |
caught — provenance must be emitted by attest.yml via cosign |
workflow_dispatch: added alongside workflow_call: on attest.yml |
caught |
id-token: write granted to a job that does not sign |
caught |
actions/checkout SHA replaced with @v7 |
caught |
Fifth platform added to NVCRECTL_PLATFORMS without updating the asset lists |
caught |
The sole-signer criterion is covered on both of its paths (a cosign invocation in a run: body, and the provenance action in a uses:), which is the one I'd have expected to be weakest.
Also confirmed: no network calls, no cluster, passes cleanly alongside the existing test/releasepolicy suite (42s full package), so #274's last criterion — "Runs in the existing ci.yml" — is satisfied by construction.
The only thing blocking this is lint — 9 findings, all mechanical, no logic changes needed. make lint currently fails, which is presumably why it is still a draft. Specifics inline.
Context worth having: #305/#306/#307 landed the weekly image scan since this was opened, and the C4 pinning check is not hypothetical for it — dependabot moves anchore/scan-action weekly under patterns: ["*"], and #306 had to add a runtime assertion precisely because nothing guaranteed that pin stays a pin. This test would cover that class directly.
Add mutation-tested coverage in test/releasepolicy for the four NVIDIA#274 invariants that were still unenforced: attest.yml as sole signer and workflow_call-only, id-token: write only on signing jobs, SHA-pinned actions, and NVCRECTL_PLATFORMS vs the hardcoded expected-asset lists (ADR-074). Give the post-publish gate a BINARIES= list so that drift fails make test.

workflow_policy_test.go redefined workflowFiles(), which NVIDIA#293 added to shell_scope_test.go with an equivalent body, and releaseWorkflow, which NVIDIA#293 also added to predicate_parse_test.go with the same value. Both redeclarations broke compilation of package releasepolicy after rebasing onto main, taking make test down with it. Delete both duplicates and call the package-level helpers instead. onReleasePath and releasePathWorkflows (also in shell_scope_test.go) are not reused here: this file's checks are meant to scan every workflow, not just the release-path subset, so narrowing them would weaken the coverage. (This branch's release.yml hunk, which edited the 'Verify published release assets' step, was dropped during the rebase onto main: NVIDIA#293 deleted that step in favor of the verify-release job, so the hunk no longer applies. The requirement it was adding is already met on main's BINARIES= list.) Signed-off-by: asivanadi0 <asivanadi0@users.noreply.github.com>

The lint fixes touched real iteration (
That is all five of #274's acceptance criteria, plus the sixth (runs in I had prepared the same lint fixes locally before seeing yours land — they were effectively identical, so I have discarded mine rather than push over your branch. Nothing needed from me. Only thing left is taking it out of draft. Worth landing soon: nothing on |

In `@test/releasepolicy/workflow_policy_test.go`:
- Line 54: Extend the sole-signer scan in the test loop over workflowFiles to
also discover and inspect .github/actions/*/action.yml files. Parse composite
action files using their top-level runs.steps structure, then apply the same
cosign-signing validation to those steps while preserving the existing workflow
jobs.steps handling.
- Around line 173-175: Update TestIDTokenWriteOnlyOnSigningJobs and its
permission parsing to resolve effective id-token permissions from workflow-level
settings, overridden by job-level settings when present. Support scalar read-all
and write-all permission forms during YAML unmarshalling, and use the resolved
value when validating non-signing jobs.
