Deploy Workflow Stops Before Any Job Starts

The deploy workflow is rejected before any job is scheduled, so none of tonight's changes can reach production.

Stage 7 of 7 in Friday Deploy Meltdown.

Briefing

Last stop on the Friday release train: the deploy workflow will not start.

Every push to main after a small edit this afternoon has been rejected before a single job was queued, so the changes the team spent the evening on are stuck.

The branch filter and the build job were approved in review and must stay exactly as they are.

Sam suspects the Actions runner pool, which was moved to a new runner image today.

The fix is yours to find: hints, the recovery checks and the debrief unlock inside the incident.

How it plays

    Get paged

    The alert fires and the clock starts. Read the page and the briefing.

  2. 02

    Investigate

    Work in a simulated shell with realistic output: logs, configs, services.

  3. 03

    Fix it

    Change the system the way you would in production. Hints are there if you get stuck.

  4. 04

    Prove it

    Automated checks verify the recovery, then the debrief explains what happened.

Checkout Hotfix Is Missing From Main

The retry change that passed checkout testing is absent from main, so the release build would ship the old behaviour.
