The migration script `a01d_locale_not_null.py` threw an `IntegrityError` (`psycopg.errors.NotNullViolation`) because the `locale` column in table `pages` still contained `NULL` values when `op.alter_column(\"pages\", \"locale\", nullable=False)` was executed.\n- **Current State:** Staging automatically remained on release `r41` because the failure occurred during `pre_deploy`.\n- **Rollback Behavior:** Rolling back via `shipctl rollback` changes traffic routing but does not execute hooks or revert database migrations. Reverting a migration requires creating and deploying a new migration release.\n\n### Unresolved Questions / Tasks\n- None. Both questions have been answered. The user has not yet decided or requested next actions regarding fixing the migration or backfilling the `pages.locale` data."

Asked for root-cause analysis on why the subsequent release `r43` failed.\n3. Inquired about the log retention period for the staging environment.\n\n### Tools Used\n* `read_deploy_log`\n\n### Context & Key Information Obtained\n* **Rollback Mechanics:** Running `shipctl rollback` reroutes traffic to an earlier release without executing hooks, meaning database migrations are not reverted. Migrations must be reverted via a new migration release. Staging remained on `r41` because `r42` failed during `pre_deploy`.\n* **Release r43 Failure:** Inspection of the deploy log (`read_deploy_log`) showed the Alembic migration completed successfully, but the deploy timed out during health checks. Replicas continuously returned `503` on `GET /healthz` because `SEARCH_INDEX_URL is empty`. Consequently, `shipctl` aborted the rollout, leaving staging on `r41`.\n* **Log Retention:** Staging logs are stored for 14 days (compared to 30 days in production) before deletion.\n\n### Unresolved Tasks / Next Steps\n* The `SEARCH_INDEX_URL` environment variable or secret needs to be configured in staging so the application can pass health checks upon redeployment."
