ci: alert when a deploy run sits queued or pending for hours - #766
Conversation
- A deploy run that never starts holds the job-level concurrency group (<cloud>-tfstate-<env>, cancel-in-progress false), so every later deploy and rollback waits behind it. GCP and Azure dev deploys were frozen from 2026-10-05 this way and nothing alerted. - New scheduled workflow deploy-queue-watchdog lists queued and pending runs of the deploy and rollback workflows every 30 minutes and fails when any is older than 120 minutes, with the run list in the job summary. It is alert-only (actions: read); waiting runs, which are waiting for an environment approval, are not reported. - scripts/check-stuck-deploy-runs.sh holds the decision logic and scripts/test-check-stuck-deploy-runs.sh covers it with a fixed clock (11 cases); the workflow runs the self-test on pull requests that touch these files. Closes #708

📝 WalkthroughWalkthroughThe pull request adds a shell checker and self-test for stale queued or pending deploy runs. A GitHub Actions workflow collects runs from six deploy and rollback workflows, reports runs at least 120 minutes old, and returns the checker’s exit status. ChangesDeploy queue watchdog

Merge Risk: 🟡 Moderate · up to The watchdog does not change how deploys run, but it can fail to alert on stuck deploys. A run whose deploy or rollback job is waiting behind another job shows as in progress rather than queued, so the watchdog skips it. Fixing detection based on job state before merge would make the watchdog reliable for the incident it targets. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Do not stop the search at 50 runs per status.
If a workflow has more than 50 queued or pending runs, --limit 50 can omit older runs—the runs most likely to exceed the threshold. Paginate until the collection covers all matching runs, or establish a bounded query that still includes the oldest outstanding runs. The CLI defines this flag as the maximum number fetched.

Base the alert on deploy-job state, not only workflow-run state.
--status filters workflow runs. The target workflows apply concurrency to jobs, so a run can be in_progress while its deploy or rollback job remains queued. This checker does not inspect jobs and can miss a blocked job after the 120-minute threshold. Collect the relevant deploy or rollback job state for the alert decision, while preserving the existing environment-approval exclusion.
The claim that a run can be queued while another job is executing is not established here. The supported failure is the missed in_progress run with a queued deploy job.

Subject: PR 766 @ 7e160e1 - REQUEST CHANGES (1 substantive finding), rest verified Verdict at 7e160e1: REQUEST CHANGES on finding F1; everything else checks out. F1 (substantive): excluding Verified at the SHA: |
- The AWS dev orphan in #708 (run 37447887010) held its concurrency group in the waiting state, not queued, and dev has no approval gate, so ignoring waiting would have missed one of the three stuck runs. - waiting is also the state of a run awaiting a required environment approval, so it alerts only after WAITING_AFTER_MINUTES (default 720) and is labeled "waiting (approval or orphaned)"; queued and pending keep the 120 minute threshold. - Self-test: waiting runs older than the waiting threshold (and exactly at it) are reported, a waiting run does not use the short threshold, an invalid waiting threshold is rejected. Three of these fail against the previous script.

Summary
Fixes the prevention half of #708. A deploy run that never starts holds the job-level concurrency group (
<cloud>-tfstate-<env>,cancel-in-progress: false), so every later deploy and rollback waits behind it. GCP and Azure dev deploys were frozen from 2026-10-05 that way and nothing alerted. The two stuck runs named in the issue are already cancelled and deploys are running again, so this PR does not touch them..github/workflows/deploy-queue-watchdog.yml: runs every 30 minutes (and on demand). It listsqueued,pendingandwaitingruns ofdeploy-gcp,deploy-azure,deploy-aws-lambda,deploy-aws-fargate,deploy-allandrollback, and fails when a queued or pending run is 120 minutes old or older, or a waiting run is 720 minutes old or older. The run list goes to the job summary. A failed scheduled run is the alert.scripts/check-stuck-deploy-runs.sh: the decision logic, reading thegh run listJSON on stdin.scripts/test-check-stuck-deploy-runs.sh: 15 cases with a fixed clock; the workflow runs it on pull requests that touch these files.Design choices:
actions: read. It does not cancel anything: aqueuedrun could be legitimate on a busy runner pool, and an automatic cancel of a deploy is not something to add without the owner asking for it. The failing summary prints thegh run cancelcommand.waitingruns are reported only after 720 minutes and labeled "waiting (approval or orphaned)": the AWS dev orphan in chore(ci): orphaned queued GCP/Azure deploy runs block the deploy pipeline; add a queue watchdog #708 (run 37447887010) showed up aswaitingon an environment with no approval gate, butwaitingis also a run awaiting a required approval, hence the longer threshold.What is verified

Finding F1 from deployment-investigation-kimi (waiting excluded, so the AWS orphan would have been missed) is fixed in the second commit. Three of the new self-test cases fail against the previous script (verified).
