Both are -cheap, and they compose (a queued workflow usually finds the lock free). - -### Pre-migration checkpoint - -Before any DDL, the entrypoint records a row in `_migration_checkpoints` -(`phase = 'pre'`, `status = 'started'`) carrying: timestamp, the last applied -migration from `_prisma_migrations` (the schema version), the git SHA, the Job -name, and the command being run.

"Previous" means `github.event.before` on pushes and -the merge commit's first parent (base-branch tip) on pull requests; when no -previous revision exists — first push of a ref — the job skips with an -explicit `::notice::` instead of failing. - -### Failure path - -1. The Job fails or hits its `activeDeadlineSeconds` → the CD `migrate` job - prints the Job logs, emits `::error::`, and exits non-zero. -2. `staging`/`production` are skipped: **the rollout is halted**. -3. A notification is POSTed to `SLACK_WEBHOOK_URL` (Environment secret); when - the secret is unset the step degrades to a `::notice::` so the omission is - visible without inventing a second failure. -4.
