Mergeability Score: 🟡 Moderate · up to Changing the Redis key prefix can split revision state during a rolling deployment while old keys remain valid, leading to inconsistent recommendation revision ordering. Migration or dual-read handling, plus confirmation that dependent services do not require the old prefix, is needed before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Add a Redis key migration before rollout.
The 24-hour TTL allows old keys to survive a rolling deployment. Old and new backend instances then enforce revision ordering on separate keys. Add migration or dual-read handling. Confirm that the external FastAPI service does not depend on the old prefix.
