This is a parallel evaluation deployment. BookOrbit remains online and both applications may index the same final library, but only Grimmory's dedicated BookDrop is writable. Do not enable file rename, move, delete, or metadata write-back against /books during the evaluation.

Create the first library at container path /books. Set GRIMMORY_DB_PASSWORD and GRIMMORY_DB_ROOT_PASSWORD only in the Arcane project environment; do not commit their values.

Before an upgrade, dump the grimmory MariaDB database and back up /opt/media-core/appdata/grimmory/data. Image tags describe the release and the pinned OCI index digests are authoritative.
