## Change

- Restored image: `ghcr.io/aerialytic/kafka-file-download:2.0.0`.
- Rollback overlap: `45` seconds.
- Final bad-version pod stopped: `2026-07-15T20:01:56Z`.

## Verification

- Deployment last observed `3/3 Ready`, zero restarts.
- Latest 15-minute logs: 3 completed downloads, 0 fresh 429, 0 DLQ sends, 0 processing errors.
- Last 429 in measured window: `2026-07-15T20:36:09.138Z`.

## Boundary
