MinIO withdrew its Docker Hub images, so the backup's upload container sat in ImagePullBackOff from 2026-09-12. With concurrencyPolicy Forbid that one stuck job also blocked every later nightly run: no kamouniverse backup for 4 days. Pin quay.io/minio/mc to a release tag; same fix for the mediamtx encode job.
