• Discovery lists (TMDB, MDBList, and Trakt): complete or explore a curated list the way you complete a collection, grouped by source in the Discover tab. A TMDB list takes a pasted themoviedb.org/list URL or a bare id, a Trakt list a numeric id or slug, MDBList a type-ahead picker.
• Curated book subjects: complete every book tagged with an OpenLibrary subject as a Books set.
• Explore a source: a Run button on the report tries any source (studio, keyword, Discogs label, or TMDB/MDBList/Trakt list) without a full scan; Clear explorations removes them again.
• Music and books are on by default, and Creator works surfaces an owned actor or director's missing series, not just their films.
• Series completeness follows your library's own providers: each series is merged across the metadata providers your Shows library uses (TheMovieDb, TheTVDB, TVmaze) season by season in your order, with your own missing-episode list as the last-chance fallback; episodes reconcile by air date and folded title, so a renumbered, reordered, or merged two-part episode is recognized as owned. The per-provider checkboxes are gone (TheTVDB still needs its key). Re-check one series without a full rescan; a partly-owned long-running show keeps its earlier and later missing seasons, and each series shows its year so a reboot is told from the original.
• Discogs completes a record label's releases and an owned artist's discography (the albums MusicBrainz misses); the artist scan follows a library Discogs id and album-level masters, so it is fast and a stray single no longer reads as a missing album.
• Diagnose and the identification audit now cover albums and books, explain an episode-numbering mismatch (a two-part or off-by-one), and offer Export for AI analysis, a Markdown dossier.
• A personal TODO list: add any gap, grouped by domain and verified against your library, with a Markdown checklist export.
• Send a missing movie or series to Radarr, Sonarr, or Jellyseerr from the report.
• Virtual placeholders for any domain: a missing series, album, or book becomes a tagged, reversible placeholder on its set, artist, or author.
• A clearer report: settings regrouped into Complete what you own and Discover new titles; every tab labelled for the media type in view (Series completion, Discography, Artist works, Author works, Discover) with the gap counts dropped; larger row titles, collapsible sections, shorter shareable links, and a fixed Markdown export filename.
• Sturdier scans: a transient provider failure mid-scan no longer blanks a collection's or discography's gaps, a multi-episode file counts across its whole span, a failed report load shows an error instead of spinning, an item mistagged with a bogus MusicBrainz id is skipped, an optional Detailed API logging toggle aids debugging, and no API key reaches the server log.
