Closes #394

Motivation / Context

Container run39523373357 failed before PHPUnit with a generic guard exception. The response was not logged; the underlying mismatch remains undetermined. This PR improves diagnosis, not retry policy.

Changes

  • Split the existing compound guard into the same ordered predicates with distinct static diagnostics for run ID, repository, attempt type/value and lifecycle status.
  • Preserve fail-closed behavior, exact comparisons, permissions, triggers and status publication. No response values, token, or environment dump.
  • Add deterministic tests executing the actual embedded PHP program with only GitHub transport substituted, including invalid/missing fields, non-running statuses, hostile status text and successful three-status publication.

Verification

  • Focused PHP8.4.26/PHPUnit12.5.38: 13 tests,115 assertions PASS; before implementation12 diagnostic assertions failed while valid path passed.
  • Installed local PHPUnit/Yaml reused; final run used temporary native-equivalent Safe I/O adapters because local vendor lacks Safe. No dependency downloads or vendor modifications. Hosted CI must validate real dependencies/full suite.
  • PHP lint and git diff --check PASS. Independent test-guardian/quality-pipeline review found no functional regression; its Safe-import recommendation applied.
  • Full composer dev-tools/actionlint unavailable locally; not claimed.

Documentation / Generated Output

No public API or generated assets change. Existing isolated-publisher contract remains intact. Related #362 and future Testing ownership #380.

Changelog

Added .changelog/pending-status-diagnostics.md (fixed/patch).

Reviewer Notes

No attempt to fix unproven eventual consistency. No retries, guard relaxation, permissions, triggers, secrets, merges or releases. PR376 untouched.

📝 Summary

Summary by CodeRabbit

  • Bug Fixes
    • Improved validation for pending test statuses by separately checking run identity, repository, attempt details, and workflow status.
    • Error messages now identify the specific validation issue, making failures easier to diagnose.
    • Invalid workflow runs no longer publish test-status updates or expose sensitive response details.
    • Valid workflow runs continue to publish all expected pending statuses.

The pending-status publisher now reports separate diagnostics for run identity, attempt, and lifecycle validation failures. New tests exercise invalid and valid publisher runs, including status-write and output checks.

Changes: Pending status validation

Layer / File(s) Summary
Separate workflow validation checks
.github/workflows/tests.yml
The publisher checks the run ID, repository, attempt type and value, and in_progress status separately. Each failed check reports a distinct diagnostic.
Publisher regression tests
tests/GitHubActions/PendingTestStatusWorkflowTest.php, .changelog/pending-status-diagnostics.md
Tests run the embedded publisher with controlled API responses. They check diagnostics and confirm rejected runs make no status writes, valid runs make three status writes, and output does not expose the marker token. The changelog records the diagnostics change.

Priority: ➖ Normal

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: php-fast-forward

Merge Risk: ⚪ Minimal · up to 60779

The change is mergeable after normal checks. As a follow-up, asserting the status-write arguments would better protect the successful publication path.

Explanation

Issue #394 requires distinct static diagnostics, fail-closed validation, deterministic embedded-publisher tests, and preserved publication behavior. .github/workflows/tests.yml now checks run ID, repository, attempt type, attempt value, and in_progress status in order with separate static messages. The new test executes the embedded PHP, covers missing and invalid fields, non-running and hostile statuses, asserts failure before status writes, and verifies the valid path publishes three statuses. The diff preserves exact comparisons and does not add retries or guard bypasses.

Full details: Docstring Coverage

Explanation

Docstring coverage is 75.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 4 functions across 1 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

- Around line 99-101: The valid-path test’s transport stub in the pending-status
workflow test accepts any status write without checking its arguments. Update
the `githubApi` transport closure to record each status-write argument list,
then assert the three expected pending-status requests, including their endpoint
and payload fields, after the publisher runs; preserve the existing
`STATUS_WRITE` response behavior.
