test(dictionary): pin concurrent snapshot writers to one surviving snapshot

Give each concurrent writer a distinct title, length, and term text so the assertion identifies which writer's snapshot survived instead of only checking that the file parses with the expected entry count.
fix(dictionary): isolate concurrent snapshot writes and shorten zip build blocks

 ## Highlights
 ### Added
-
- **Sync Stats & History**
-  - New **Sync Stats & History** window (tray menu) and `subminer sync <host>` command keep mining stats and watch history in sync between machines over SSH, with saved devices, per-host sync direction, and live stage-by-stage progress.
-  - Merges are safe to repeat: data combines without duplicates, and hosts with auto-sync enabled sync automatically in the background on a schedule, reporting results as overlay notifications.
-  - Manual snapshot tools (create, merge, reveal, delete) and connection testing cover one-off transfers; Windows machines running the built-in OpenSSH Server work as sync remotes too, with no setup needed beyond SSH access. Power users can script transfers directly with `--push`/`--pull`, `--check`, `--snapshot`/`--merge`, and `--json` flags.
-
- **TsukiHime Subtitle Downloads**
-  - Download Japanese and secondary-language subtitles for the current video directly from TsukiHime, mirroring the existing Jimaku flow.
-  - Press `Ctrl+Shift+T` to search by tabs for the primary and secondary languages; the matching release is found automatically from the video filename and loads straight into mpv, no API key required.
-
- **Post-Playback History Menu**
-  - After a watch-history episode ends or mpv closes, the fzf/rofi launcher returns to that series with options to play the previous or next episode, rewatch, pick another episode, or quit SubMiner.
-  - Previous/Next continue across season directories, so you can binge a show without manually browsing folders.
-  - The menu shown right after picking a series from `subminer -H` now offers the previous episode too, matching the post-playback menu.
-
- **Known-Word Highlighting by Anki Maturity**
-  - Subtitle highlights for known words can now be colored by Anki card maturity (new, learning, young, mature), similar to asbplayer. Enable it with `ankiConnect.knownWords.maturityEnabled`, or toggle it live during a session.
-  - The mature-interval threshold and the four tier colors are configurable, and the in-session help legend shows the active tier colors while maturity highlighting is on.
-  - Tiers follow Anki's own card state: a lapsed card correctly shows as learning rather than young, and a note is treated as mature if any of its cards are mature. Stats and other known-word tools stay accurate with this new data.
-
- **Stats Library Entry Deletion**
-  - Added a "Delete Entry" action in the stats Library detail view that removes an entire title in one step: every episode, session, subtitle line, rollup, cover, and vocabulary count derived from it. Previously a mistaken entry had to be cleared episode by episode and still lingered in the Library.
-  - Delete progress (session, session group, episode, or full entry) now shows app-wide as a progress bar plus a status toast, staying visible across tabs and windows instead of disappearing when you switch away.
-  - Deletes are dramatically faster on large libraries, and opening the Vocabulary tab no longer stalls; the first launch after upgrading migrates the stats database in place to support this.
-
-### Changed
-
- **Clipboard-Video Shortcut**
-  - The "append clipboard video to queue" shortcut is now configurable via `shortcuts.appendClipboardVideoToQueue` instead of being fixed.
+- **Library Merge and Move**
+  - Duplicate library cards for the same show can now be combined: select cards in the library grid, choose "Merge Selected," and pick which entry to keep. Sessions, mined cards, and watch time move over, and future episodes stay matched to the merged card.
+  - Episodes can be reassigned to a different library entry with a "→" button on the episode row, fixing cases where a file lands under the wrong title. Manual assignments survive later filename parsing, Jellyfin refreshes, and season repair.
+  - Exact AniList matches with compatible seasons now merge automatically, while fuzzy matches show up as a dismissible "Possible duplicate" prompt instead of merging without confirmation.

 ### Fixed
+- **Anki Audio Generation on Network Drives**
+  - Fixed sentence-audio generation timing out on slow network-mounted video files with many subtitle and font-attachment streams.
+  - Extraction now uses bounded probing and a two-minute budget, and failures show a clear error instead of a cryptic one.
+- **Duplicate Subtitle Line Stats**
+  - Fixed karaoke openings and animated signs (which record one subtitle event per animation frame) inflating word and kanji counts and skewing "Top Repeated Words." Ordinary repeated dialogue and rewatches are unaffected.
+  - Already-inflated stats can be cleaned up with the new "Duplicates" button in the Vocabulary tab, or `subminer stats cleanup --duplicate-lines` (supports `--dry-run` and `--lookback-days`). Only the affected subtitle lines and vocabulary counts are touched; watch time and lines-seen totals are untouched.
+- **Overlay Modals on macOS and Windows**
+  - Fixed overlay modals and the stats window opening on the wrong macOS Space, or forcing a Space switch, when mpv is fullscreen. They now open above fullscreen mpv on its current Space.
+  - Modals are now prewarmed on macOS and Windows so shortcuts open them promptly, and Windows keeps the hidden modal responsive between sessions.
+- **Wayland File Drag-and-Drop**
+  - Fixed dragging subtitle and video files from file managers like Thunar onto the overlay on native Wayland; dropped files are now resolved and sent to mpv.
+- **Windows Mouse Lag**
+  - Fixed system-wide mouse lag while SubMiner is running on Windows, caused by a global mouse hook and blocking window lookups during click-through tracking.
+- **Mining Clip Accuracy**
+  - Fixed mined audio and animated image clips sometimes capturing the wrong subtitle line when audio extraction was slow. The clip range is now locked in at the moment of lookup, so audio and image clips always match.
+- **Linux Notifications**
+  - Character dictionary progress notifications on Linux now update in place instead of flickering off and back on with every status change.
+- **Stats Delete Performance**
+  - Fixed stats deletes freezing the dashboard; deletes now reliably run off the main thread, with automatic retry if the delete worker crashes.
+  - Deletes, library merges/moves, and AniList reassignments are now much faster because totals are updated incrementally instead of rebuilt from scratch, and no longer erase lifetime totals older than the recent session history.
+  - Session deletes on large libraries dropped from minutes to milliseconds.

- **Word Highlighting Accuracy**
-  - Fixed several incorrect word highlighting and annotation cases: inconsistent part-of-speech exclusions on merged quote-particle tokens, missing annotations for rare kanji, katakana punctuation wrongly treated as non-kana noise, and certain kanji vocabulary skipped for next-level ("N+1") highlighting.
-
- **AniList Season Resolution**
-  - Season 2 and later episodes now resolve to the correct AniList entry by walking sequel relations instead of guessing from the title, so watch progress, the character dictionary, and cover art for later seasons no longer silently fall back to season 1.
-  - Manual AniList overrides now stay in effect for every episode in the same season (by folder and detected season), and setting an override now fixes both the character dictionary and AniList watch progress together instead of needing separate corrections.
-
- **Startup Playback Pausing Too Early**
-  - Fixed playback resuming before subtitle processing finished warming up, which could briefly show untranslated subtitles right after opening a video.
-  - Most noticeable when resuming mid-episode or when a subtitle cue starts within the first couple of seconds.
-
- **Linux AppImage Crash Notification on Quit**
-  - Fixed a spurious "Service Crash" desktop notification appearing after closing a video when running the Linux AppImage.
-  - If needed, the mount-keepalive behavior behind this fix can be disabled with `SUBMINER_NO_APPIMAGE_MOUNT_KEEPALIVE=1`.
-
- **AnkiConnect Proxy Port Conflict**
-  - Fixed video playback failing to start when another process already held the configured AnkiConnect proxy port; SubMiner now shows a notification explaining how to resolve the conflict instead of crashing.
-
- **Stats & Settings Reliability**
-  - Fixed session stats reporting zero known words after the known-word cache gained maturity tiers.
-  - Hardened the stats server against malformed requests, stalled AniList lookups, media mismatches during word mining, and missing Yomitan connections.
-  - AnkiConnect settings validation now preserves valid custom configurations while safely falling back on invalid values instead of failing.
-
- **Stats Library Cover After Relink**
-  - Relinking a title to a different AniList entry now updates its cover art in the stats Library grid, not just the detail view, so unrelated titles no longer end up sharing the wrong cover.
-
- **Rofi Menu Prompt Spacing**
-  - Rofi menu prompts now keep a space between the prompt label and the input field instead of crowding the search placeholder text.

sudacode	354e3ea2e5	test(dictionary): pin concurrent snapshot writers to one surviving snapshot Give each concurrent writer a distinct title, length, and term text so the assertion identifies which writer's snapshot survived instead of only checking that the file parses with the expected entry count.	2026-08-17 11:10:38 -07:00
sudacode	9df2f37d4b	fix(dictionary): isolate concurrent snapshot writes and shorten zip build blocks The streamed snapshot writer keyed its temp file on the pid alone, so two overlapping writes for the same media (a manual generate racing auto-sync) streamed into one file and tore it; add a per-write sequence suffix. Term banks were stringified 10k entries at a time, measured at ~38MB and ~135ms per bank on a real merged dictionary. Halving that block matters more than the write itself: at 2k entries the longest event-loop stall in a merged build drops from ~135ms to 28ms.	2026-08-17 02:46:27 -07:00
sudacode	1228ebe622	fix(dictionary): stop character dictionary IO from blocking the main process Generating and importing a large character dictionary froze the whole app long enough for the compositor to raise its application-not- responding dialog over the player. Multi-hundred-MB snapshot JSONs and the merged archive were read, written, and zipped synchronously on the main process, and the character image / name-candidate caches re-read every cached snapshot synchronously inside a lookup whenever the snapshot directory changed. - snapshot reads/writes are async; writes stream in slices and rename into place so a crash or concurrent writer cannot tear a snapshot - buildDictionaryZip yields between ~8MB slices and CRC32 uses the native zlib implementation - the image and name-candidate lookup caches rebuild in the background and serve the previous index while the rebuild runs Worst main-thread stall over a 1.4GB snapshot set drops from 8s+ to under 700ms.	2026-08-17 01:45:54 -07:00
