A new Discogs source completes curated record labels and an owned artist's discography (needs a Discogs token), via the type-ahead chip picker. Diagnose goes deeper and wider: a networked deeper pass tells a real misidentification from a coincidental title clash; episode and season gaps get reboot-aware diagnosis (the V 1984 versus V 2009 case); albums and books are diagnosable. The report links out everywhere: music rows to MusicBrainz and Discogs, books to OpenLibrary, the Diagnose ids are clickable, and each creator or set group header links the source itself (author, actor or director, artist, studio, keyword, label, collection, series). Every provider link carries a per-provider CSS class (cgProvider-...), a data-provider attribute, and a title and aria-label, so a theme can inject service icons including icon-only; the README has a ready-to-paste snippet under Advanced CSS customization. Under the hood: a read-through cache in front of every external call, proactive per-service rate pacing (MusicBrainz and Discogs), a circuit breaker that moves the scan past a down service, longer caching of stable id-to-name lookups, and a concurrent scan that streams results into the report per item. The library no longer reports a reboot's later seasons as missing episodes of the single-season original, a Name-plus-year match prefers an exact-year hit, and the Books (OpenLibrary) source is hardened against real author data. Settings: the Discogs toggle and token sit in Data sources; Markdown exports are named by domain.
