 6. If the read-only checker reports a pending migration, stop app deployment and run `Migrate Staging Database` manually with the same full SHA; a successful migration re-dispatches `Deploy staging` with that same SHA.

-Application rollback uses the same workflow: manually dispatch `Deploy staging` from the `main` controller with a previous known-good full SHA that has a successful `Staging Backend Quality Gate` run, and explicitly set `allow_rollback=true`. Normal and migration-triggered deployments reject stale, divergent, or backward revisions. Rollback still consumes the selected gate run's digest manifest, which is retained for 30 days; if it has expired, rerun that exact SHA's gate run to regenerate the immutable manifest before dispatching rollback. Database migrations are separate and are not rolled back by an application deployment. Restore a staging database backup before running any destructive migration rehearsal.

Normal and migration-triggered deployments reject stale, divergent, or backward revisions. Rollback still consumes the selected gate run's digest manifest and is supported only during that artifact's 30-day retention window; after expiry, stop and prepare a separately reviewed republish/recovery change rather than substituting a mutable tag or assuming the old run can still be rerun.
