Repeated apply_migration failures

Part of the Cost & ops health check · fix arrives as a guide

What it is

The project shows repeated apply_migration operation failures in its control-plane history.

Why it matters

Migrations are failing on retry, which usually means the schema is now in a partially-applied state. Each subsequent deploy tries again and fails the same way, so the schema drifts further from what the code expects.

How to fix it

Read the failure detail on the operation, then reconcile the actual schema against the migration history before running more. A migration that half-applied usually needs manual repair rather than another retry.
