Description
The installed Copilot Pull Request, Commit and Branch Sync workflows in Domus PR 61 concluded as failures before any Action step ran. A retry on the same head failed again. No native Copilot Verification or current-head Bugbot check was produced. The prior revision received a normal Bugbot review. The expected outcome is that the exact revision is reviewed or that a runner or scheduling diagnostic identifies a safe recovery.
Reproducing the issue
- Inspect PR 61 after its branch advanced to
d2c3bae6a7664fe902dfb9247c7584f9ea020c80. - Inspect the Pull Request workflow, Commit workflow and Branch Sync workflow.
- On attempt 1, the Pull Request jobs API returned one failed job with an empty step list and zero check annotations. The job's completion timestamp precedes its reported start timestamp. Commit and Branch Sync returned zero jobs.
- Rerun the same workflows without moving the ref. All three attempt-2 jobs APIs returned zero jobs and the workflow conclusions were
failure. - The documented read-only review comment started an Issue Comment job and reached the Run Copilot step on a later dispatch.
copilot Version
vypdev/copilot@v3 resolved to ace49e4a7ce0f6a007fef5d11479eb9b7a5846e3 on the latest successful Domus review. The affected attempts did not reach action setup.
Additional context and comments
The pre-step failure also coincided with an incomplete job inventory in the independent CI workflow. The available evidence shows a GitHub workflow scheduling or reporting failure affecting the installed integration. It does not establish a fault in the Copilot action code or a particular upstream cause. This differs from a native verification rejection, a provider failure inside the Action, or a stale review result. Keep all required exact-head checks active.

A later retry recovered dispatch. The previously affected Pull Request workflow, attempt 3 started and completed its native job. On the current revision the Commit workflow, attempt 2 also reached the Action. It reported the distinct, non-retryable source-citation capacity failure tracked in #957. The independent CI retry has now dispatched all nine prerequisite jobs, including both image architectures.
