+  # Node 24, and the docker-gated real-stack probe (the issue's test plan:
+  # "start with pending migrations and confirm readiness waits" — the app's
+  # migration run is blocked behind a held ACCESS EXCLUSIVE lock on the
+  # migration ledger, /health stays not-ready, then flips ready once the lock
+  # releases) runs where a Docker daemon is available and skips cleanly
+  # otherwise. The job installs the frozen workspace and builds the
