bvandeusenandClaude Opus 5.5	5b372f61d7	feat: the same song on several releases counts as one song (M498 #5438) ... A single and the album it is on stay two files, since each fulfils its own release in Lidarr, but they are one song to the listener. - tracks.song_id links copies; the generated song_key (song_id, else the track's own id) is what they share (migration 0076). - The resolver links each cross-release group every pass (idempotent; only with auto-resolve on) and, when a link is new, shares existing likes across the song and logs them for sync. - A like or unlike (web and Subsonic) reaches every copy; each change is logged and published so clients update every heart. - The Liked list and its count show the song once; Shuffle and the mix writer take one copy per song. - A merge keeps the removed copy's song link; "Not the same song" on the Across releases tab dismisses the group and undoes the link. Shared plays ("heard via another copy") are left for a later step. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-08 22:07:55 -04:00
bvandeusenandClaude Opus 5.5	4ecff52f19	feat: duplicates resolve themselves where Lidarr says it is safe (M498) ... The duplicate sweep proposed 4,197 groups and every one waited for the operator. Most are safe to settle, and Lidarr defines what safe means: it maps one file to each track of the release it monitors and downloads any mapped file that disappears. Deleting a mapped copy opens exactly the hole the operator saw Lidarr fill. Classify (#5435) - Migration 0075: duplicate_groups.class (same_release, cross_release, mismatch, review), resolve_note, resolved_automatically; duplicate_group_members.lidarr_state (tracked, unmapped); fingerprint_settings.auto_resolve; notification kind duplicates_resolved with both kind CHECKs swapped (rule 36). - library.ClassifyDuplicateGroup, with MatchTitleKey dropping featuring credits, remaster notes and video-rip markers, and keeping live, demo, remix and instrumental. The rip markers move from api to library. Choose the copy to keep (#5436) - ProposeSurvivor ranks the copy Lidarr maps first, then tag fit (a clash-free track number, no rip marker in the name, an MBID), then the quality rules. File size picked the wrong Humanz copy in 6 of 21 groups. Act (#5437) - An hourly resolver pass reads Lidarr's unmapped files, matched by the last three path components, and records each copy's state. - Same album, with at most one copy mapped: merged into the mapped copy. The merge is guarded, so a mapped copy can never be removed (MergeDuplicateGroupGuarded, ErrCopyTrackedByLidarr). - Same album, every copy mapped: the monitored release lists the song twice (Humanz's 14x12" box set). The pass moves Lidarr to the release that lists each song once and best covers what is on disk. It never picks one covering less, and is capped at 10 albums per pass. - Fixed point (lesson #4183): the chosen release no longer repeats. - The album is left alone for 24h while Lidarr rescans, so "every copy unmapped" mid-rescan is never read as licence to merge. - Both actions are audited with no actor and summarised to admins. The operator can switch them off in the Fingerprinting card (rule 25). - Manual merges use the same guard: 409 copy_tracked_by_lidarr, or 503 lidarr_unavailable when Lidarr cannot say. Web - Duplicates gets tabs: Needs review, Across releases, Resolved automatically. Each loads as you scroll (rule 172), replacing the pager. - Each copy says whether Lidarr uses it. - The resolver's note shows on each group. - The merge confirm blocks, before sending, a merge that would remove the copy Lidarr uses.

bvandeusenandClaude Opus 5	077ae61235	feat(admin): fingerprinting settings — on/off, length, match threshold, concurrency, sweep interval (M400 #3913) ... Rule 25: the fingerprinting knobs move out of source into a DB-backed singleton (migration 0061), edited from a card on the Duplicates page and shared live with the scanner, the backfill and the duplicate sweep through one service instance, so a save needs no restart. The length is the knob that can silently break the library: prints taken at two lengths never match. Each track_fingerprints row now records the length it was taken at, and every reader filters on the current one — the backfill treats another length as stale, the gauge counts it pending, the sweep never streams it. Equivalent to a version bump, except that setting the length back makes rows not yet redone current again. The card warns before a length change re-fingerprints the library. Off stops every decode: the scan takes only the stream hash (a demux, and what recognises a moved file) and stores nothing, dropping a changed file's stale row; the backfill idles. A save also makes a sweep due, since a new threshold or length changes what the same prints group into, and the sweep interval gains slack so an hourly interval on an hourly tick doesn't skip every other tick.

bvandeusenandClaude Opus 5	11ef044ef6	feat(library): merge duplicates without losing history (M400 #3911) ... Merge keeps one copy of a duplicate group and removes the rest. Every table that references tracks does so ON DELETE CASCADE, so deleting a duplicate's row outright would silently destroy its likes, plays, playlist entries and tags. The merge moves all of that onto the kept copy first, then deletes the empty row. In one transaction, holding a lock on the group: - repoints play_events, skip_events, contextual_likes, playback_errors, lidarr_requests.matched_track_id and playlist_tracks. The last is keyed by position, so every entry stays where it was. - merges general_likes one per user, dated to the earlier like - takes the union of track_tags, keeping the kept copy's own weight on a shared tag - rewrites track_similarity onto the kept copy, dropping edges that would point a track at itself and keeping the kept copy's existing edge on a collision - lets the kept copy take a recording MBID only the removed copy had - deletes the removed copies' rows, tidies emptied albums and artists, marks the group merged - logs sync changes: track deletes, and like and playlist-track delete/upsert pairs The removed copies' files are deleted first, before any row changes, through the same helper as DeleteTrackFile (now shared, along with the album tidy-up). A merge that left the file behind would be undone by the next scan re-importing it. An unwritable library answers 409 library_not_writable and nothing changes. tracks.Service.MergeDuplicates wraps it with the opt-in Lidarr unmonitor from RemoveTrack, skipped when the removed copy is a second file of the kept copy's own album track: unmonitoring that would stop Lidarr managing the kept file. It writes a duplicate_merge audit row after commit, per the audit package's best-effort contract, naming both paths. POST /api/admin/library/duplicates/{id}/merge takes an optional survivor_track_id (the report's proposal otherwise) and unmonitor. On the report page: - each copy gets a Keep choice, defaulting to the proposed one - Merge needs a second click, on a button that says how many files it removes, with the consequence stated beside an opt-in Lidarr checkbox Integration tests cover: - every piece of history landing on the kept copy exactly: likes deduped at the earlier time, plays and skips counted, playlist position unchanged, tags unioned, similarity rewritten with no duplicate or self-edge, MBID inherited - the removed file gone, and a second merge refused - an unwritable file leaving likes, plays, row and group untouched - a survivor outside the group refused Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SQ31KQpYbStyK5y58UmPLH	2026-09-11 17:25:06 -04:00
bvandeusenandClaude Opus 5	ff493a8c7d	feat(admin): the duplicates report — review proposed duplicate groups (M400 #3912) ... A new admin tab, Duplicates, beside Missing files: the proposals from the duplicate sweep, with a Sweep now trigger and a Not duplicates dismissal. Nothing on it merges or deletes; the merge is #3911. Each group shows: - whether it is identical audio or the same recording, with a match percentage from the weakest link between members - every copy's format, size, duration, path, and the likes and plays it carries (every user's; this is admin-only, and it is what decides which copy to keep) - the copy proposed to keep, and the rule that chose it The survivor rule is library.ProposeSurvivor, a pure function the merge will reuse: lossless over lossy, then the larger file, then the copy in the library longest, then lowest id. Bitrate is not in it because the scanner never fills tracks.bitrate, and for one recording at one duration a larger file is the higher bitrate. m4a is not counted as lossless: it may be AAC. The reason names the rule that separated first place from second, not every rule the winner passed. An empty report has three causes, and the page says which: still fingerprinting, the sweep has never run, or it ran and found nothing. The sweep's state and the backfill's progress come back with the groups for that reason. Groups left with fewer than two members since the sweep are not shown. GET /api/admin/library/duplicates, POST .../sweep (202, or 409 sweep_in_progress), POST .../{id}/dismiss (404 duplicate_group_not_pending when already resolved). Migration 0060 indexes play_events by track_id. Its only indexes led with user_id, so each copy's play count, and the merge's repointing of play history, would scan the whole table. Web only, like Missing files: Android has no library-health admin screens.
