🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Stop unrelated runs from cancelling the queued final-status publisher.

Lines 10-12 set concurrency for the whole workflow, keyed only by head_sha. GitHub keeps only one waiting workflow run per concurrency group by default. When a new job or workflow run is queued, any existing pending job or workflow run in the same group is canceled and replaced. cancel-in-progress: false does not prevent this. That setting only protects the run that is already in progress.

The group is assigned before the job-level if on lines 16-19 runs. Every workflow_run event from "Fast Forward Test Suite" for the same SHA therefore joins the group, including events that the if later skips. Two examples are a workflow_dispatch run and a push run by a different actor.

How the failure happens:

  1. A requested or in_progress handler is running for the Dependabot run.
  2. The completed handler waits in the group.
  3. A lifecycle event from a non-Dependabot run on the same SHA arrives. It replaces the waiting completed handler.
  4. That new handler is then skipped by the if.

Result: the Run Tests (<version>) statuses stay pending. Branch protection blocks the Dependabot PR until someone re-runs the workflow.

Events from the same Dependabot run are safe. Each handler reads the current run state, and any event type for a completed run publishes the final statuses (lines 130 and 167).

Fix: set queue: max. Waiting handlers then queue in order and nothing replaces them. Each handler re-validates the run before it writes, so running stale handlers one after another is safe.

Review comment at @.github/workflows/test-statuses.yml around lines 10 - 12:
Set the workflow-level concurrency policy to queue up to the supported maximum
by adding queue: max to the concurrency block keyed by workflow_run.head_sha.
Keep cancel-in-progress: false so queued lifecycle handlers run in order without
replacing pending handlers.
