• There is a high-confidence, high-severity migration risk in alembic/versions/96470fdcc686_v2_backfill_catalog_and_access.py: the per-org try/except does not handle PostgreSQL transaction-abort behavior after a failed statement.
• If one org-level conn.execute() fails, subsequent statements in the same transaction can keep failing (InFailedSqlTransaction), which can cause the backfill to stop or leave data changes incomplete.
• Given the concrete failure mode and likely user-visible migration impact, this is high risk to merge until transaction handling is adjusted (e.g., SAVEPOINT/nested transaction strategy).
• Pay close attention to alembic/versions/96470fdcc686_v2_backfill_catalog_and_access.py - per-org error handling currently won’t recover after database-level statement failure.

Check if these issues are valid — if so, understand the root cause of each and fix them. If appropriate, use sub-agents to investigate and fix each issue separately.

<violation number="1" location="alembic/versions/96470fdcc686_v2_backfill_catalog_and_access.py:563">
P1: The per-org `try/except` won't recover from database-level errors without a SAVEPOINT. In PostgreSQL, a failed statement inside a transaction marks it as aborted — all subsequent `conn.execute()` calls will raise `InFailedSqlTransaction`, causing every remaining org and the preset backfill to fail too.

Wrap each org's work in `conn.begin_nested()` (which emits `SAVEPOINT` / `ROLLBACK TO SAVEPOINT`) so the outer transaction stays healthy after an individual org failure.</violation>

The data migration can fail or backfill incorrect data for supported existing database states, notably duplicate secret environments and pre-existing custom providers.

Full review comments:

• [P1] Filter provider secrets by environment — alembic/versions/96470fdcc686_v2_backfill_catalog_and_access.py:307-310
  When an organization has the same agent credential name in multiple secret environments, this lookup ignores organization_secret.environment, so .one_or_none() raises and blocks the whole migration; if only a non-default environment exists, the migration can also copy credentials/grant access that the agent service would not use because runtime lookups default to the default environment. Add the environment column and filter these provider-secret queries to the default environment.

• [P1] Do not reuse arbitrary custom providers — alembic/versions/96470fdcc686_v2_backfill_catalog_and_access.py:436-440
  For orgs that already have custom-provider rows when this migration runs, this unscoped lookup either raises MultipleResultsFound if there is more than one provider or attaches the legacy custom-model-provider catalog entry to an unrelated existing provider without copying the legacy ciphertext onto that provider. The backfill needs to find a migration-created/provider-specific row or create a dedicated one for the legacy secret.
