- bookva-minio (stack 49): mirror books (38692 obj) → volume bookva-minio-data-new (docker volume rename unavailable on old daemon)
- backup script (repo + host /opt/stacks/backup/run.sh) repointed to live paths
- runbook Track A progress + gotchas (mc --disable-multipart, sequential mirrors on 3.8G host, CRLF secret)
