Administration
Arcagrad is multi-user, and a few things are reserved for administrators — the account you create on first run is an admin.
Accounts
Section titled “Accounts”The first account is the admin. Admins manage the shared library — adding and removing items, editing metadata, and installing plugins — and add other accounts from the server’s user management. Everyone else is a reader: they can read, and they keep their own progress, favorites, and ratings, but they don’t change the library.
Personal state is always per user; the library itself is shared.
API access
Section titled “API access”Arcagrad has a full REST API. Create a personal API key to use it from scripts or other tools — see the REST API reference. A key acts as your account, so treat it like a password.
Backups
Section titled “Backups”Everything Arcagrad generates lives in /data — the database, thumbnails, tags,
reading progress, and settings. Back it up and you’ve saved all of it.
Recovery
Section titled “Recovery”Lost the database? Point a fresh Arcagrad at the same library and it rebuilds the index by
scanning — your files are the source of truth. Scraped metadata (tags and descriptions) isn’t
re-derived from your files, so a /data backup is the only way to bring it back — otherwise
you re-fetch it with plugins.
