Steady throughput for the last 30 minutes. Delay < 5min.

our autoscaling responded slower than expected, but responded nonetheless. the backlog is draining

### identified, 2026-08-18 12:27 UTC

evaluation throughput was overwhelmed by a slow tenant/model workload, with lock-expiry retries multiplying work; the concurrent worker rollout prolonged the incident.
