What this run covers

Synthetic project item records only; no production data or traffic.
Two independent instances of the pinned upstream FastAPI backend with real login and item CRUD routes; synthetic data.
Sequential interleavings; no concurrent transactions or load test.
No lock-duration, large backfill, replication, or production deployment verification.
Rollback means returning to v1 code on the migrated schema, not undoing SQL.
GO applies only to this fixture and these declared probes.

The migration passed. Old-version requests failed.
