Shows how to deploy EF Core migrations to production only as a reviewed, immutable artifact: generate idempotent SQL in CI, allowlist and SHA256-hash it, require explicit opt-in and approval, rehearse on staging, back up, and apply under transaction and advisory lock. Use for gated production EF Core releases. Not for…

Isolates fraud agent rule testing from production: runs tests against a mirrored sandbox or historical replay, blocks test execution when the target environment is live, and tags test traffic so it can never train models or trigger fulfilment. Use when an agent test evaluated rules on real orders. Not for shadow mode …

How to clean an alembic autogenerate migration polluted with unrelated schema noise from another branch: reviewing the diff, deleting the noise, and regenerating on a clean baseline. Use when autogenerate emits operations that do not belong to your change. Not for autogenerate missing a change you expected.
Recovery and prevention after an agent ran prisma migrate dev against a shared staging database and wiped data URIs restoring from backup, and the guardrails that keep migrate dev off shared databases. Use when migrate dev reset a database it should never have touched. Not for migrate deploy issues.
