- library: CRUD with root-path resolution (absolute, symlink-free, must be readable). A library name is unique; the root is validated at creation. - registry: media types declare their extensions; the core never imports a module. RegisterType is the extension point. - scanner: walks a root, reconciles media_items/media_files in one transaction, skips unchanged files by size+mtime, and marks vanished files missing rather than deleting them (progress is the one thing here that cannot be regenerated). A single unreadable file never fails a scan. - migration 0002: `missing` flags on items and files, plus indexes. - endpoints: media-types, library list/get/create/delete, per-library items, and scan. Library reads go through the same grant chokepoint as everything else; an unauthorised library 404s rather than 403s so its existence is not leaked.
