+name: subminer-release
+description: Prepare, cut, publish, or repair SubMiner stable and prerelease releases. Use for hands-on release work; do not use for general release questions.
+---
+
+# SubMiner release
+
+Carry out the requested release phase using the repository's current release process.
+
+## Source of truth
+
+Read `docs/RELEASING.md` completely before changing files or release state. Treat it as canonical. Read `changes/README.md` when the work touches change fragments or generated release notes.
+
+Do not copy release commands or policy into this skill. If this skill disagrees with the release guide, follow the guide and reconcile the skill before handoff.
+
+## Workflow
+
+1. Identify whether the request is for a stable release, prerelease, release preparation, publication, or repair.
+2. Inspect the current branch, worktree status, package version, pending change fragments, relevant tags, and latest CI state before making changes.
+3. Follow the matching procedure in `docs/RELEASING.md` in order. Review generated changelog and release-note Markdown before it can be committed or published.
+4. Run every required gate for the requested release phase. Do not treat a cheaper test lane as a substitute for the documented release gate.
+5. Before a stable tag, confirm the package and tag versions match and no pending `changes/*.md` fragments remain. Preserve fragments for prereleases as documented.
+6. Report the resulting version, completed checks, local commit and tag state, remote publication state, skipped platform checks, and any remaining manual work.
+
+## Authorization boundaries
+
+- A request to prepare a release stops before commit, tag, push, or remote publication unless the user also authorizes those actions.
+- A clear request to cut or publish a release includes the documented commit, tag, and push steps. Ask before the first remote mutation when the wording is ambiguous.
+- Do not edit an existing GitHub release, publish to the AUR, change secrets, or alter signing configuration unless the user explicitly requests that operation.
+- Do not switch branches without consent.
+
+## Stop conditions
+
+Stop and report the blocker when required CI or a release gate fails, authentication is missing, versions disagree, required artifacts are absent, or the worktree contains unexpected changes that overlap the release. Do not tag or publish a partially verified release.

 # Changelog
 
+## v0.19.6 (2026-09-04)
+
+### Added
+
+- **Card Timing Review**:
+  - Optional pre-generation timing review for word, sentence, and audio cards, with a speech-weighted waveform that flattens background noise so dialogue edges stand out clearly.
+  - The clip end automatically snaps back to where the line's dialogue actually ends once the waveform loads, with drag and keyboard adjustments available.
+  - Audio preview includes a sweeping playhead that plays the clip to its true end, even on high-latency outputs like Bluetooth headphones.
+  - Previous and next subtitle lines can be pulled onto the card with `P`/`N` (or the Prev/Next steppers) and removed with Shift; the sentence preview and waveform markers update automatically.
+  - Cancelling lets you keep a card without media, and the review can be toggled on or off for the session.
+- **Senren Field Grouping**:
+  - Enable `ankiConnect.isSenren` to merge duplicate mined cards using Senren's scene-switching markup, grouping sentence, furigana, audio, picture, and misc-info fields.
+  - Supports the same auto/manual/disabled modes as Kiku, including the manual merge modal; only one of Senren or Kiku can be enabled at a time.
+
+### Changed
+
+- **Remote Stream Mining Performance**: Mining a card from a remote stream (Jellyfin and other HTTP sources) now downloads the clip window once and reuses it for the timing review waveform, audio preview, audio extraction, and screenshot, instead of re-fetching the stream at each step; the temporary file is cleaned up after ten minutes of inactivity or on exit.
+- **TsukiHime Release Filtering**: The TsukiHime modal's Japanese and secondary-language tabs now filter the release list by the subtitle languages each release actually carries, and report when no release has subtitles for the active tab.
+
+### Fixed
+
+- **Subtitle & Mining Accuracy**:
+  - Broadcast-style captions that split one sentence across two on-screen rows (e.g. Crunchyroll Japanese subs) now merge into a single line for the sidebar and mined cards, while separate speakers, sound effects, and labeled turns still stay on their own lines.
+  - Mining from the overlay no longer pulls in a lingering row from the previous caption; the mined sentence and clip timing now match what's actually on screen.
+  - Multi-line copy and mining now select lines backward in timeline order after seeking, instead of in playback encounter order.
+  - Copying a subtitle, mining a sentence, or recording immersion stats no longer includes the separate furigana line that broadcast ASS captions place above a word.
+- **Card Update Notifications**: Dismissed lingering overlay card-update progress when notification settings switch to OSD before an update finishes.
+- **Overlay Stability on Hyprland**: Opening a modal window (timing review, Jimaku, session help, and others) while mpv is fullscreen no longer causes the overlay to flicker while the modal loads; the overlay now stays on screen untouched until the modal is ready.
+- **Jellyfin Subtitle Sync**: Jellyfin subtitle files now load with zero mpv delay instead of inferring and saving an offset from Japanese and English cue timelines.
+- **Secondary Subtitle Visibility**: Native mpv secondary subtitles stay hidden when switching secondary subtitle tracks during playback.
+
+## v0.19.5 (2026-08-30)
+
+### Fixed
+
+- **Anki Card Update Progress**: The card-update spinner now stays visible until audio and image updates finish, instead of disappearing early.
+- **Anki Word-Card Fields**: Word-card enrichment now writes sentence text and audio to the fields configured in AnkiConnect, while the dedicated sentence-card and audio-card actions keep their existing compatible field names.
+- **Overlapping Subtitles**:
+  - Subtitle lines that start while another line is still on screen now appear alongside it, instead of staying hidden until a track switch or seek.
+  - Subtitles shown at the same time now stack by their authored screen position, with top signs and song lines above bottom dialogue.
+  - Half-size ASS furigana is no longer shown as if it were a dialogue line.
+- **YouTube Auto Captions**:
+  - Auto-generated captions now follow their intended timing and two-row roll-up layout.
+  - Long speech is paged instead of covering the video with a wall of text.
+  - Explicitly timed sound cues like `[音楽]` no longer cover later dialogue.
+
+## v0.19.4 (2026-08-25)
+
+### Added
+- **Library Merge & Move**: Duplicate library cards for the same show can now be combined. Select cards in the library grid and use "Merge Selected" to pick which entry to keep and move every episode onto it, preserving sessions, mined cards, and watch time. Episodes can also be reassigned individually via the "→" button, useful when a file lands under a stray title; manual assignments survive later filename parsing, Jellyfin refreshes, and season repair. Exact AniList title matches with compatible seasons now merge automatically, while fuzzy matches surface as dismissible "Possible duplicate" reviews instead of merging silently.
+- **Duplicate Line Cleanup Tool**: The Vocabulary tab's new "Duplicates" button scans a chosen time window (7 days through all time) for old karaoke/typeset duplicate-line bursts, shows what it found, and collapses each run to one line once confirmed; `subminer stats cleanup --duplicate-lines` does the same from the terminal, with `--dry-run` and `--lookback-days <n>` options. Watch time and lines-seen totals are left unchanged.
+
+### Changed
+- **Prerelease Release Notes**: Prerelease notes now open with a "Changes since" section listing only what changed versus the previous beta/RC of the same version, above the cumulative highlights, and CI rejects prerelease tags whose committed notes were generated for a different beta/RC.
+
+### Fixed
+- **Subtitle & Karaoke Duplication**:
+  - Karaoke and animated signs are reconstructed once from their authored text and shown only while actually sung, with original word spacing preserved, instead of flooding the overlay, subtitle sidebar, immersion history, mining, or stats with glyph fragments, per-frame color phases, and repeated animation events.
+  - Decorative layers (highlight sweeps, glow/shadow copies, symbol-font decoration, particle swarms, hidden or zero-scaled text) stay out of published text, while ordinary repeated dialogue, positioned signs, wrapped lyric rows, and multi-row CC-style blocks still display correctly.
+  - Embedded subtitle tracks on network-mounted (SMB/NFS) media are extracted and parsed again instead of falling back to live-text-only, restoring karaoke reconstruction, sidebar cues, and mining for releases that only ship subtitles inside the container.
+  - Secondary subtitles go through the same deduplication pipeline as primary subtitles and no longer clip display after about four lines.
+  - Event-heavy karaoke files that previously stalled subtitle loading for several seconds now parse in well under a second.
+- **Character Dictionary Reliability**:
+  - Generation, merged rebuilds, and imports no longer freeze the app on large dictionaries; snapshot I/O, archive building, and image/name lookup caches moved off the UI's critical path.
+  - Dictionaries are reused instead of regenerated when MeCab finds no name splits.
+  - Cached portraits restore correctly after the portrait index finishes loading post-tokenization.
+  - Desktop progress notifications on Linux AppImage installs update in place instead of flickering, fixing a bug where the AppImage's bundled libraries broke the system notification helper.
+- **Overlay Startup & Modals**:
+  - The macOS window-tracking helper targets macOS 12.0+ instead of requiring the build machine's exact macOS version, fixing crashes on older systems like Ventura that left the overlay stuck on "Overlay loading".
+  - mpv IPC connection attempts time out and retry, showing an actionable error if content still isn't ready after 30 seconds.
+  - Dedicated overlay modals are prewarmed on macOS and Windows so shortcuts open them promptly.
+  - On macOS, reused modals and the stats window open above fullscreen mpv on its current Space instead of jumping to another desktop.
+- **Wayland File Drop**: Fixed native Wayland drag-and-drop from file managers such as Thunar, so subtitle and video files dropped on the visible overlay are resolved and forwarded to mpv.
+- **Windows Mouse Lag**: Fixed system-wide mouse lag on Windows while SubMiner is running, caused by the overlay's global mouse hook for click-through forwarding and by the mpv window tracker blocking the app on repeated PowerShell lookups.
+- **Sentence Mining Audio & Clips**: Sentence-audio generation no longer times out on slow network-mounted media with many subtitle/font streams (bounded FFmpeg probing, two-minute extraction budget, clearer error reporting), and mined audio/animated AVIF clips now capture the subtitle line that was actually mined by snapshotting the clip range at lookup time instead of reading live mpv state later.
+- **Stats Performance & Reliability**: Immersion stats storage now sets its SQLite busy timeout before WAL setup, avoiding transient lock errors under concurrent writes. Deletes in the stats dashboard no longer freeze the UI, run proportional to what's deleted instead of rebuilding full lifetime summaries, retry safely if the delete worker crashes, and no longer rescan the whole library when deleting very common words; a new index also makes large session deletes drop from minutes to milliseconds. Library merges, video moves, and AniList reassignments got the same lifetime-summary fix.
+- **Vocabulary Stats Accuracy**: Vocabulary totals and charts now count all tracked vocabulary instead of only the first page, new-word history uses corrected daily rollups (fixing legacy timestamp and time-zone issues), summary cards refresh automatically after edits to the exclusion list, and rapid exclusion edits no longer race each other.
+- **Rofi MKV Thumbnails**: Fixed missing MKV thumbnails in the Linux rofi picker when system thumbnailer registrations only advertise legacy Matroska MIME aliases.
+

+<summary>Internal changes</summary>
+
+### Internal
+- Docs Site Indexing: Excluded the `/main/` and `/v/<version>/` docs trees from search indexing (self-referential canonical, `noindex,follow`, matching `X-Robots-Tag`) so crawlers focus on current docs instead of ~30 archived copies of every page, and restored `<lastmod>` dates in the docs sitemap that were silently dropped by production builds.

@@ -42,13 +42,14 @@ How fragments turn into a release:
 
 - At release time, `bun run changelog:build` (and `bun run changelog:prerelease-notes`) pipes every pending fragment through `claude -p` to merge related items, drop noise, and rewrite into a clean user-facing release body. Write fragments as raw, informative notes — don't worry about polished prose, deduping across PRs, or line-by-line phrasing. The polish step handles all of that.
 - The polish step treats pending fragments as the final release outcome, not prerelease history. If a feature is added and then renamed or fixed before the stable cut, ship the final feature bullet instead of separate prerelease-only breaking/fix entries.
-- GitHub release notes and prerelease notes use short top-level items with nested bullets for the change, user benefit, and any useful action note. The stable `CHANGELOG.md` can stay in compact single-line bullets.
+- `CHANGELOG.md`, GitHub release notes, and prerelease notes all use short top-level items with one nested bullet per distinct change, instead of packing a release's worth of detail into a single paragraph bullet. An item with only one thing to say stays inline on the top-level bullet. Release notes and prerelease notes additionally cover user benefit and any useful action note in their nested bullets.
 - `internal` fragments stay in `CHANGELOG.md` (inside a collapsed `<details>` block) but are dropped from the GitHub release notes entirely.
 - The polished `CHANGELOG.md` and `release/release-notes.md` are committed and reviewed before tagging — edit the Markdown by hand if Claude misses something.
 
 Prerelease notes:
 
 - prerelease tags like `v0.11.3-beta.1` and `v0.11.3-rc.1` reuse the current pending fragments to generate `release/prerelease-notes.md`
+- from the second prerelease of a base version onward, the notes also open with a `## Changes since <previous tag>` section generated from the fragment diff against the previous beta/RC tag; keep fragment edits meaningful. Editorial-only rewording is filtered out of that section, while genuinely changed behavior and deleted fragments (reverted changes) are reported
 - existing prerelease notes are a reviewed baseline; later prerelease runs should replace stale beta/RC wording with the current outcome instead of appending fix churn
 - prerelease note generation does not consume fragments and does not update `CHANGELOG.md` or `docs-site/changelog.md`
 - the final stable release is the point where `bun run changelog:build` consumes fragments into the stable changelog and release notes

-- Typeset subtitles no longer flood the stats. Karaoke openings and animated signs are authored as one subtitle event per animation frame, and immersion tracking counted every frame, which was enough to put an OP lyric at the top of "Top Repeated Words" for good. Lines are now collapsed on the way in using the same rules the subtitle sidebar already applies: matching parsed timings record exactly the cues the sidebar shows, while shifted, changing, or unparsed sources use a strict fallback where identical, contiguous, sub-0.1s lines stop counting after a few frames. Ordinary repeated dialogue and rewatches are unaffected.
-- Added a cleanup for stats already affected. The Vocabulary tab has a **Duplicates** button that scans a chosen window (7 days through all time), shows the bursts it found and the word and kanji counts they added, and collapses each run to one line once confirmed. `subminer stats cleanup --duplicate-lines` does the same from the terminal, with `--dry-run` and `--lookback-days <n>`. Only subtitle lines and the vocabulary counts they feed are touched; watch time and lines-seen totals are left as recorded.

-- Library: duplicate cards for the same show can now be combined. Press "Select" above the library grid, tick the cards, and use "Merge Selected"; the dialog picks which entry to keep and moves every episode onto it. Sessions, mined cards, and watch time are preserved, the emptied entries disappear, and remembered title aliases keep future episodes on the merged card.
-- Library: episodes can be reassigned to another library entry from the "→" button on an episode row, which is the fix when one file lands under a stray title (e.g. an episode name parsed as the series). Manual assignments now survive later filename parsing, Jellyfin refreshes, and season repair. Local episodes in the same directory reuse a uniquely corrected destination unless they parse to a title that already has its own library entry, while conflicting seasons or manual destinations are not forced together. Emptying an entry this way removes it and returns to the grid.
-- Library: exact AniList title matches with compatible seasons fold duplicate cards automatically. Fuzzy same-AniList matches appear as dismissible "Possible duplicate" reviews instead of changing the library without confirmation; conflicting explicit seasons are left alone.

-- If the delete worker crashes, the delete now retries on the current thread instead of failing.
-- Library merges, video moves, AniList reassignments, and `subminer stats cleanup -l` also stopped rebuilding lifetime summaries from retained sessions; they now recompute from per-episode history, so those operations are faster and no longer erase lifetime totals older than the session retention window.
-- Deleting content that contains very common words no longer rescans every occurrence of those words across the whole library; first/last-seen dates are refreshed with index seeks instead.

-## How Tracking Works
+## How tracking works
 
-SubMiner monitors playback and triggers an AniList progress update when an episode is considered "watched" -- at least 85% of the episode duration viewed and a minimum of 10 minutes watched.
+SubMiner watches playback and pushes an AniList progress update once an episode counts as watched. That means at least 85% of its duration, and at least 10 minutes either way.
 
 The update flow:
 
-1. **Title detection** -- SubMiner extracts the anime title, season, and episode number from the media filename and path. Season folders such as `Season 2` are treated as a strong season signal. SubMiner tries [`guessit`](https://github.com/guessit-io/guessit) first for accurate parsing, then falls back to an internal filename parser if guessit is unavailable.
-2. **AniList search** -- The base title (with any `Season N` / `SN` marker stripped) is searched against the AniList GraphQL API, and SubMiner picks the best match by comparing titles (romaji, English, native, synonyms) and filtering by episode count. AniList has no notion of numbered seasons -- sequels are separate entries with their own titles (`Zoku`, `Kan`, `2nd Season`), so searching `<title> Season 3` finds nothing. For season 2 and later, SubMiner instead walks `SEQUEL` relations from the season 1 entry, preferring the TV line, and falls back to ordering the franchise's TV entries by air date when the relation chain is incomplete. If neither locates the season, SubMiner **skips the update** rather than writing progress to the season 1 entry, and tells you to pin the right entry with a [character dictionary override](/character-dictionary#correcting-anilist-matches).
-3. **Progress check** -- SubMiner fetches your current list entry for the matched media. The media must already be in Planning or Watching; otherwise SubMiner shows an MPV message explaining that the update is not possible. If your recorded progress already meets or exceeds the detected episode, the update is skipped.
-4. **Mutation** -- A `SaveMediaListEntry` mutation sets the new progress and marks the entry as `CURRENT`, or `COMPLETED` when the watched episode is the final episode of the season (the "already at this progress" skip is bypassed for the final episode so completion still lands).

+## Field mapping
 
 SubMiner maps its data to your Anki note fields. Configure these under `ankiConnect.fields`:
 
 ```jsonc
 "ankiConnect": {
   "fields": {
-    "word": "Expression",           // mined word / expression text
-    "audio": "ExpressionAudio",    // audio clip from the video
-    "image": "Picture",             // screenshot or animated clip
-    "sentence": "Sentence",         // subtitle text
-    "miscInfo": "MiscInfo",         // metadata (filename, timestamp)
-    "translation": "SelectionText"  // secondary sub or AI translation
+    "word": "Expression",        // mined word / expression text
+    "audio": "SentenceAudio",    // sentence audio clip cut from the video
+    "image": "Picture",          // screenshot or animated clip
+    "sentence": "Sentence",      // subtitle text
+    "miscInfo": "MiscInfo"       // metadata (filename, timestamp)
   }
 }
 ```
 
+`fields.audio` receives the **sentence** audio SubMiner cuts from the video, not word audio. Yomitan writes its own dictionary audio when you mine, so point this at a separate field such as `SentenceAudio` to keep the two apart. The built-in default is still `ExpressionAudio`, which collides with Yomitan on note types that use that field for word audio.
+
 Field names are matched against your Anki note type case-insensitively (an exact match wins, then a lowercase comparison). If a configured field does not exist on the note type, SubMiner skips it without error.
 
+These mappings always control normal word-card enrichment, including Yomitan proxy/polling updates and manual clipboard updates. Enabling Lapis or Kiku does not replace the configured word-card sentence and audio fields with `Sentence` and `SentenceAudio`. The dedicated sentence-card and audio-card shortcuts still use those Lapis/Kiku field names.
+
 Two related options live alongside `fields`: `ankiConnect.deck` (target deck; empty falls back as described above) and `ankiConnect.tags` (tags added to mined cards, default `["SubMiner"]`; set `[]` to disable tagging). The `miscInfo` content is controlled by `ankiConnect.metadata.pattern` (default `[SubMiner] %f (%t)`; tokens: `%f` filename, `%F` filename with extension, `%t` timestamp, `%T` timestamp with milliseconds, `<br>` newline).

+For remote streams such as Jellyfin playback, SubMiner downloads the clip's time window once into a temporary Matroska file (a stream copy, no re-encoding) and reads the timing review waveform, audio preview, audio, and image from that file instead of fetching the stream again for each step. The window covers the clip plus padding, plus the visible timeline in timing review, and grows when you reveal more of the timeline.

+Set `media.reviewTiming` to `true` to pause playback and check the clip before its media is generated. It applies to word, sentence, and audio cards.
+
+The review opens on the subtitle range plus your configured audio padding. Subtitles usually hang around after the dialogue has stopped, so once the waveform loads, an untouched clip end pulls back to just after the last speech in the line. The Line end rail still marks the original subtitle timing, Reset puts it back, and a line whose speech runs right through its end is left alone.
+
+**Adjusting the clip.** Drag either edge to trim, drag the middle to slide the whole clip without changing its length, or click anywhere on the waveform to snap the nearer edge there. A focused edge also moves with the arrow keys: 100 ms per press, or 500 ms with Shift. The 100 ms buttons do the same thing. Earlier and Later each reveal two more seconds of timeline without moving the selection.
+
+**Keys.** Space previews the selection with a playhead sweeping the clip. The preview ends when the hidden player has actually played the last sample, so Bluetooth output latency does not clip the tail. Enter confirms and Escape cancels.
+
+**The waveform.** SubMiner reads a center channel when one carries dialogue and falls back to a mono mix otherwise, keeps only the 250 to 3500 Hz speech band, and draws each slice's loudness against the clip's own noise floor. Steady background music flattens out and dialogue stands up, which makes it much easier to tell adjacent lines apart. The mined subtitle appears as a tinted band with labeled line-start and line-end rails. If waveform analysis fails, the timing controls still work.
+
+The range you confirm is used exactly as-is; SubMiner does not add audio padding a second time. Static screenshots take its midpoint, and animated AVIF clips cover the whole range.
+
+**Pulling in adjacent lines.** Press `P` or `N`, or use the Prev and Next steppers above the sentence preview, to add the previous or next subtitle line. Repeat for as many lines as exist. Shift+`P` and Shift+`N` remove them again. The sentence preview lists every included line with the mined one highlighted, so you always see the sentence field before confirming. The clip bounds and the waveform rails follow the outermost added line, keeping the review's audio padding.
+
+Confirming writes the combined lines to the sentence field. Reset drops the added lines along with any timing changes. Adjacent lines come from the parsed subtitle track when one is loaded; otherwise you only get lines that already played. A clip capped by `media.maxMediaDuration` still keeps the full combined sentence even when the audio cannot stretch to cover every added line.
+
+**Canceling.** You can go back to editing, finish with the original timing, create the card without audio or an image, or discard it. Discard deletes an existing Yomitan or audio card, and skips creation entirely for a direct sentence card. A failed audio preview does not block confirmation or card creation.
+
+Clipboard updates and stats-dashboard mining never open timing review. The option is off by default and hot-reloads. **Review Media Timing** in the runtime options palette (`Ctrl/Cmd+Shift+O`) toggles it for the current session.

-### Keyboard Shortcuts in the Modal
+The merge markup depends on the note type. Kiku entries are wrapped in `<span data-group-id="...">` spans ordered newest first. Senren entries follow the [scene switching](https://github.com/BrenoAqua/Senren/blob/main/docs/scene_switching.md) format: sentence, sentenceFurigana, and miscInfo entries use `group` spans when ordinal order is sufficient and numbered `groupN` spans when they need an absolute scene target. Audio and pictures are appended positionally, and the number of sentenceAudio entries drives Senren's scene count. Ungrouped legacy content is wrapped into a group span on first merge, and source `groupN` spans are rebased after the kept note's existing audio scenes.

 # Changelog
 
+## v0.19.6 (2026-09-04)
+
+**Added**
+
+- **Card Timing Review**:
+  - Optional pre-generation timing review for word, sentence, and audio cards, with a speech-weighted waveform that flattens background noise so dialogue edges stand out clearly.
+  - The clip end automatically snaps back to where the line's dialogue actually ends once the waveform loads, with drag and keyboard adjustments available.
+  - Audio preview includes a sweeping playhead that plays the clip to its true end, even on high-latency outputs like Bluetooth headphones.
+  - Previous and next subtitle lines can be pulled onto the card with `P`/`N` (or the Prev/Next steppers) and removed with Shift; the sentence preview and waveform markers update automatically.
+  - Cancelling lets you keep a card without media, and the review can be toggled on or off for the session.
+- **Senren Field Grouping**:
+  - Enable `ankiConnect.isSenren` to merge duplicate mined cards using Senren's scene-switching markup, grouping sentence, furigana, audio, picture, and misc-info fields.
+  - Supports the same auto/manual/disabled modes as Kiku, including the manual merge modal; only one of Senren or Kiku can be enabled at a time.
+
+**Changed**
+
+- **Remote Stream Mining Performance**: Mining a card from a remote stream (Jellyfin and other HTTP sources) now downloads the clip window once and reuses it for the timing review waveform, audio preview, audio extraction, and screenshot, instead of re-fetching the stream at each step; the temporary file is cleaned up after ten minutes of inactivity or on exit.
+- **TsukiHime Release Filtering**: The TsukiHime modal's Japanese and secondary-language tabs now filter the release list by the subtitle languages each release actually carries, and report when no release has subtitles for the active tab.
+
+**Fixed**
+
+- **Subtitle & Mining Accuracy**:
+  - Broadcast-style captions that split one sentence across two on-screen rows (e.g. Crunchyroll Japanese subs) now merge into a single line for the sidebar and mined cards, while separate speakers, sound effects, and labeled turns still stay on their own lines.
+  - Mining from the overlay no longer pulls in a lingering row from the previous caption; the mined sentence and clip timing now match what's actually on screen.
+  - Multi-line copy and mining now select lines backward in timeline order after seeking, instead of in playback encounter order.
+  - Copying a subtitle, mining a sentence, or recording immersion stats no longer includes the separate furigana line that broadcast ASS captions place above a word.
+- **Card Update Notifications**: Dismissed lingering overlay card-update progress when notification settings switch to OSD before an update finishes.
+- **Overlay Stability on Hyprland**: Opening a modal window (timing review, Jimaku, session help, and others) while mpv is fullscreen no longer causes the overlay to flicker while the modal loads; the overlay now stays on screen untouched until the modal is ready.
+- **Jellyfin Subtitle Sync**: Jellyfin subtitle files now load with zero mpv delay instead of inferring and saving an offset from Japanese and English cue timelines.
+- **Secondary Subtitle Visibility**: Native mpv secondary subtitles stay hidden when switching secondary subtitle tracks during playback.
+
+## v0.19.5 (2026-08-30)
+
+**Fixed**
+
+- **Anki Card Update Progress**: The card-update spinner now stays visible until audio and image updates finish, instead of disappearing early.
+- **Anki Word-Card Fields**: Word-card enrichment now writes sentence text and audio to the fields configured in AnkiConnect, while the dedicated sentence-card and audio-card actions keep their existing compatible field names.
+- **Overlapping Subtitles**:
+  - Subtitle lines that start while another line is still on screen now appear alongside it, instead of staying hidden until a track switch or seek.
+  - Subtitles shown at the same time now stack by their authored screen position, with top signs and song lines above bottom dialogue.
+  - Half-size ASS furigana is no longer shown as if it were a dialogue line.
+- **YouTube Auto Captions**:
+  - Auto-generated captions now follow their intended timing and two-row roll-up layout.
+  - Long speech is paged instead of covering the video with a wall of text.
+  - Explicitly timed sound cues like `[音楽]` no longer cover later dialogue.
+
+## v0.19.4 (2026-08-25)
+
+**Added**
+- **Library Merge & Move**: Duplicate library cards for the same show can now be combined. Select cards in the library grid and use "Merge Selected" to pick which entry to keep and move every episode onto it, preserving sessions, mined cards, and watch time. Episodes can also be reassigned individually via the "→" button, useful when a file lands under a stray title; manual assignments survive later filename parsing, Jellyfin refreshes, and season repair. Exact AniList title matches with compatible seasons now merge automatically, while fuzzy matches surface as dismissible "Possible duplicate" reviews instead of merging silently.
+- **Duplicate Line Cleanup Tool**: The Vocabulary tab's new "Duplicates" button scans a chosen time window (7 days through all time) for old karaoke/typeset duplicate-line bursts, shows what it found, and collapses each run to one line once confirmed; `subminer stats cleanup --duplicate-lines` does the same from the terminal, with `--dry-run` and `--lookback-days <n>` options. Watch time and lines-seen totals are left unchanged.
+
+**Changed**
+- **Prerelease Release Notes**: Prerelease notes now open with a "Changes since" section listing only what changed versus the previous beta/RC of the same version, above the cumulative highlights, and CI rejects prerelease tags whose committed notes were generated for a different beta/RC.
+
+**Fixed**
+- **Subtitle & Karaoke Duplication**:
+  - Karaoke and animated signs are reconstructed once from their authored text and shown only while actually sung, with original word spacing preserved, instead of flooding the overlay, subtitle sidebar, immersion history, mining, or stats with glyph fragments, per-frame color phases, and repeated animation events.
+  - Decorative layers (highlight sweeps, glow/shadow copies, symbol-font decoration, particle swarms, hidden or zero-scaled text) stay out of published text, while ordinary repeated dialogue, positioned signs, wrapped lyric rows, and multi-row CC-style blocks still display correctly.
+  - Embedded subtitle tracks on network-mounted (SMB/NFS) media are extracted and parsed again instead of falling back to live-text-only, restoring karaoke reconstruction, sidebar cues, and mining for releases that only ship subtitles inside the container.
+  - Secondary subtitles go through the same deduplication pipeline as primary subtitles and no longer clip display after about four lines.
+  - Event-heavy karaoke files that previously stalled subtitle loading for several seconds now parse in well under a second.
+- **Character Dictionary Reliability**:
+  - Generation, merged rebuilds, and imports no longer freeze the app on large dictionaries; snapshot I/O, archive building, and image/name lookup caches moved off the UI's critical path.
+  - Dictionaries are reused instead of regenerated when MeCab finds no name splits.
+  - Cached portraits restore correctly after the portrait index finishes loading post-tokenization.
+  - Desktop progress notifications on Linux AppImage installs update in place instead of flickering, fixing a bug where the AppImage's bundled libraries broke the system notification helper.
+- **Overlay Startup & Modals**:
+  - The macOS window-tracking helper targets macOS 12.0+ instead of requiring the build machine's exact macOS version, fixing crashes on older systems like Ventura that left the overlay stuck on "Overlay loading".
+  - mpv IPC connection attempts time out and retry, showing an actionable error if content still isn't ready after 30 seconds.
+  - Dedicated overlay modals are prewarmed on macOS and Windows so shortcuts open them promptly.
+  - On macOS, reused modals and the stats window open above fullscreen mpv on its current Space instead of jumping to another desktop.
+- **Wayland File Drop**: Fixed native Wayland drag-and-drop from file managers such as Thunar, so subtitle and video files dropped on the visible overlay are resolved and forwarded to mpv.
+- **Windows Mouse Lag**: Fixed system-wide mouse lag on Windows while SubMiner is running, caused by the overlay's global mouse hook for click-through forwarding and by the mpv window tracker blocking the app on repeated PowerShell lookups.
+- **Sentence Mining Audio & Clips**: Sentence-audio generation no longer times out on slow network-mounted media with many subtitle/font streams (bounded FFmpeg probing, two-minute extraction budget, clearer error reporting), and mined audio/animated AVIF clips now capture the subtitle line that was actually mined by snapshotting the clip range at lookup time instead of reading live mpv state later.
+- **Stats Performance & Reliability**: Immersion stats storage now sets its SQLite busy timeout before WAL setup, avoiding transient lock errors under concurrent writes. Deletes in the stats dashboard no longer freeze the UI, run proportional to what's deleted instead of rebuilding full lifetime summaries, retry safely if the delete worker crashes, and no longer rescan the whole library when deleting very common words; a new index also makes large session deletes drop from minutes to milliseconds. Library merges, video moves, and AniList reassignments got the same lifetime-summary fix.
+- **Vocabulary Stats Accuracy**: Vocabulary totals and charts now count all tracked vocabulary instead of only the first page, new-word history uses corrected daily rollups (fixing legacy timestamp and time-zone issues), summary cards refresh automatically after edits to the exclusion list, and rapid exclusion edits no longer race each other.
+- **Rofi MKV Thumbnails**: Fixed missing MKV thumbnails in the Linux rofi picker when system thumbnailer registrations only advertise legacy Matroska MIME aliases.

+- Docs Site Indexing: Excluded the `/main/` and `/v/<version>/` docs trees from search indexing (self-referential canonical, `noindex,follow`, matching `X-Robots-Tag`) so crawlers focus on current docs instead of ~30 archived copies of every page, and restored `<lastmod>` dates in the docs sitemap that were silently dropped by production builds.

+SubMiner builds a Yomitan-compatible dictionary of a show's characters from [AniList](https://anilist.co), the online anime and manga database. Once it is loaded, character names in subtitles get recognized and highlighted, and hovering one shows the portrait, role, voice actor, and biography without leaving the overlay.
 
-This is helpful because proper names rarely appear in normal dictionaries, so character names would otherwise be flagged as "unknown" words and clutter your mining. Recognizing them keeps your N+1 highlighting focused on real vocabulary.

 An override also pins the entry used for [AniList watch progress](/anilist-integration), so correcting a wrong match once fixes both the character dictionary and progress tracking.

History is session-only and is not persisted across restarts.
 
 Startup tokenization, subtitle annotation, and character dictionary status follow the configured notification surface. When the surface is `"overlay"` or `"both"`, SubMiner queues those startup notifications until the overlay renderer is ready instead of falling back to mpv OSD. If loading and ready states both finish before the overlay can paint, the loading card is delivered first and then updates to ready shortly after. With `"both"`, character dictionary checking/building/importing/ready status also goes to system notifications; building and importing are only emitted when that work is actually needed. The bundled mpv plugin only shows its startup OSD messages when `ankiConnect.behavior.notificationType` is set to `"osd"` or `"osd-system"` in `config.jsonc`; AniSkip prompts and skip result messages are playback feedback and still route to overlay notifications when configured.
 
 The equivalent direct CLI command is `--playback-feedback <text>` (`playbackFeedback` internally). It sends that one non-empty feedback string through the same route controlled by `ankiConnect.behavior.notificationType`; it does not change the saved config.

 Karaoke openings and animated signs are authored as one subtitle event per animation frame, all carrying the same text. Playback reports every one of those frames, so a single OP lyric could be recorded hundreds of times and dominate "Top Repeated Words".
 
 Recording now collapses those runs as they happen, matching what the subtitle sidebar shows:
 
+- When a typeset ASS file stores a clean lyric or sign in a timed authoring comment, or in full-line events surrounding generated fragments, the matching complete line is recorded once. The repeated glyph or clip-animation frames are not recorded. Dialogue spoken while such an animation is on screen records as itself, without the fragment lines beside it.
+- When karaoke styling redraws the same complete lyric across consecutive color or highlight phases, those phases are combined into one line with their full timing. Repeated ordinary dialogue remains separate.
 - When the active subtitle source has been parsed, its cue list has already had duplicate events and animation bursts merged. A line landing inside a surviving cue but after that cue's start is a frame the sidebar merged away, and is not recorded.
 - When no parsed cue covers the live timing, including while a subtitle source is changing or shifted, the strict metadata-free rule applies: a run of identical, contiguous lines each shorter than 0.1s stops being recorded after a few frames. Runs are tracked per line of text, so dual-line karaoke (a kanji and a romaji line frame-flipped together) collapses both lines. Ordinary repeated dialogue, and lines held for a normal beat, always record.

The `subminer` launcher handles this automatically when `--backend x11` is set or the X11 backend is auto-detected.

 ::: tip Tokenization
-SubMiner's primary tokenizer is Yomitan itself - subtitle text is tokenized based entirely on the dictionaries you have installed in Yomitan. Installing many large dictionaries can increase noise and slow down lookups, so be selective about which dictionaries you install and their priority order.
+Yomitan is the tokenizer, so the dictionaries you installed there decide where word boundaries fall. Piling on large dictionaries adds noise and slows lookups. Be picky about which ones you install and what order you rank them in.
 :::
 
 Before any of those layers render, SubMiner strips annotation metadata from tokens that are usually just subtitle glue or annotation noise. Standalone particles, auxiliaries, adnominals, common explanatory endings like `んです` / `のだ`, merged trailing quote-particle forms like `...って`, auxiliary-stem grammar tails like `そうだ` (MeCab POS3 `助動詞語幹`), repeated kana interjections, and similar non-lexical helper tokens remain hoverable in the subtitle text, but they render as plain tokens without known-word, N+1, frequency, JLPT, or name-match annotation styling.
 
 Kanji vocabulary that MeCab labels `名詞/非自立`, such as `日` or `以外`, remains content for every annotation layer. The `非自立` exclusion only suppresses kana grammar nouns such as `こと` and `もの`.

+The subtitle sidebar puts the whole parsed cue list for the active subtitle file in a scrollable panel next to mpv.

-## How It Works
+## How it works
 
 When SubMiner parses the active subtitle source into a cue list, the sidebar becomes available. Toggle it with the `\` key (configurable via `subtitleSidebar.toggleKey`). While open:
 
 - The active cue is highlighted and kept in view as playback advances (when `autoScroll` is `true`).
-- Clicking any cue seeks mpv to that timestamp.
-- The sidebar stays synchronized with the overlay - media transitions and subtitle source changes update both simultaneously.
+- Clicking any cue seeks mpv into that line. For overlapping ASS karaoke, SubMiner moves past the previous line's exit animation when the selected cue has enough time remaining.
+- The sidebar and the overlay share one cue list, so a media change or subtitle source switch updates both at once.
 
-The sidebar only appears when a parsed cue list is available. External subtitle sources that SubMiner cannot parse (for example, embedded ASS tracks rendered directly by mpv) will not populate the sidebar.
+For typeset ASS karaoke and animated signs, SubMiner collapses generated animation frames and repeated full-line color phases before they reach the sidebar. It recovers a clean complete line from a matching timed authoring comment or from full-line events surrounding generated fragments. Ordinary ASS comments, editor notes, alternate lines, repeated dialogue, and separately positioned signs remain distinct.
 
-## Layout Modes
+The sidebar only opens when a parsed cue list exists. Subtitle sources SubMiner cannot parse, such as embedded ASS tracks that mpv renders itself, leave it empty.
+
+## Selecting and copying dialogue
+
+Drag across subtitle text to select an excerpt, including across multiple rows. Scroll to extend a selection through a longer conversation. `Ctrl/Cmd+C` or the **Copy** button copies the highlighted text in subtitle order, without timestamps. Partial first and last lines are preserved, with a blank line between subtitle cues.
+
+Dragging to select does not seek playback. Playback-following auto-scroll stops while you drag or have a selection, so the excerpt stays in view. Press `Escape` to clear the selection. An ordinary click with no selection still seeks to that cue.
+
+Selection survives playback updates and Yomitan popup dismissal. Changing media or subtitle sources, refreshing the cue list, or closing the sidebar clears it. Copying an excerpt does not require creating an Anki card.
+
+## Layout modes
 
 Two layout modes are available via `subtitleSidebar.layout`:
 
 **`overlay`** (default) - The sidebar floats over mpv as a panel. It does not affect the player window size or position.
 
-**`embedded`** - Reserves space on the right side of the player and shifts the video area to mimic a split-pane layout. Useful if you want the cue list visible without it covering the video. If you see unexpected positioning in your environment, switch back to `overlay` to isolate the issue.
+**`embedded`** - Reserves space on the right side of the player and shifts the video area over, giving you a split pane. Use this when you want the cue list up without it covering the video. Positioning depends on the compositor, so switch back to `overlay` if the geometry comes out wrong.

 - **Mouse passthrough**: On Linux X11/Xwayland, SubMiner uses `xdotool` to poll the cursor and only enables overlay input while the cursor is over subtitle or popup regions. Outside those regions, pointer input passes through to mpv. Native Wayland compositors other than Hyprland/Sway cannot provide the stacking control SubMiner needs.

 This is the multi-language companion to the [Jimaku integration](/jimaku-integration). Releases that ship multiple languages (e.g. Netflix `[MultiSub]` rips) expose them all; the modal's tabs pick which ones you see, and each download is saved with its own language suffix.

-The integration runs through an in-overlay modal opened with `Ctrl+Shift+T` by default.

Tracks with no language tag stay visible on the secondary tab.
+The integration runs through an in-overlay modal opened with `Ctrl+Shift+T` by default. The modal has two tabs that filter both the release list and the subtitle tracks of the selected release by role: the first follows `secondarySub.secondarySubLanguages` (English when unset), and the second is always **Japanese**, the currently supported primary subtitle language. Each tab lists only the releases whose reported subtitle languages include the tab's language, so the Japanese tab hides the many releases that ship English subtitles only. Releases and tracks with no language tag stay visible on the secondary tab. If nothing on the active tab qualifies, the status line says so and points at the other tab.
 
 When you open the modal, SubMiner parses the current video filename to extract a title and episode number (same parser as Jimaku - `S01E03`, `1x03`, `E03`, and dash-separated numbers all work). If the filename yields a high-confidence match, SubMiner auto-searches immediately.

 2. **Browse releases** - Select a release to list the text subtitle tracks extracted from its files. English tracks sort first; image-based tracks (PGS/VobSub) are filtered out.
 3. **Download** - Selecting a track downloads the xz-compressed subtitle from TsukiHime's storage, decompresses it, saves it next to the video (or a temp directory for remote/streamed media), and loads it into mpv. Japanese tracks are selected as mpv's **primary** subtitle. Tracks from the configured secondary tab are assigned to mpv's **secondary** subtitle slot without replacing the primary. The filename carries the track's language - `<video basename>.en.<ext>` for English, `.ja` for Japanese, and so on - so mpv and media servers detect the language correctly.
 
-Because releases on TsukiHime are the same files circulating as torrents, picking the release that matches your local file (same group, same version) gives you subtitles with exact timing - no resync needed.

-SubMiner auto-loads Japanese subtitles when you play a YouTube URL, giving you the same sentence-mining overlay experience as local video files. It probes available subtitle tracks via `yt-dlp`, selects the best primary and secondary tracks, downloads them, and loads them into mpv before playback resumes.
+Play a YouTube URL and SubMiner loads Japanese subtitles for it, so mining works the same as it does on a local file. It probes the available tracks with `yt-dlp`, picks a primary and a secondary, downloads both, and loads them into mpv before playback resumes.
 
 ## Requirements
 
 - **[yt-dlp](https://github.com/yt-dlp/yt-dlp)** must be installed and on your `PATH`. yt-dlp is a free command-line tool that reads YouTube video and subtitle info; SubMiner calls it behind the scenes. (`PATH` is the list of folders your system searches for programs - most installers add yt-dlp to it automatically. If yours did not, set `SUBMINER_YTDLP_BIN` to the full path of the yt-dlp binary.)
 - mpv with `--input-ipc-server` configured (handled automatically when you launch playback through the `subminer` launcher - no manual setup needed).
 
-## How It Works
+## How it works
 
 When SubMiner detects a YouTube URL (or `ytsearch:` target), it pauses mpv at startup and runs a subtitle pipeline before resuming playback:
 
-1. **Probe** --- `yt-dlp --dump-single-json` extracts all available subtitle tracks (manual uploads and auto-generated captions) along with video metadata. Every yt-dlp call passes `--no-playlist`, so playlist links (for example a Watch Later URL with `list=`/`index=`) resolve to the single video instead of the whole playlist.
-2. **Discover** --- Each track is normalized into a `YoutubeTrackOption` with language code, kind (`manual` or `auto`), display label, and direct download URL.
-3. **Select** --- SubMiner picks the best primary track (Japanese, preferring manual over auto) and secondary track (English, preferring manual over auto).
-4. **Download** --- Selected tracks are fetched via direct URL when available, falling back to `yt-dlp --write-subs` / `--write-auto-subs`. YouTube TimedText XML formats (`srv1`/`srv2`/`srv3`) are converted to VTT on the fly. Auto-generated VTT captions are normalized to remove rolling-caption duplication.
-5. **Load** --- Subtitle files are injected into mpv via `sub-add`. Playback resumes once the primary track is ready; secondary failures do not block.

-## Card Media Cache
+## Card media cache
 
 By default, YouTube card audio and screenshots are extracted directly from mpv's active stream URLs. If generated card media fails with YouTube `403` errors, set `youtube.mediaCache.mode` to `"background"`. Background mode starts a separate `yt-dlp` media download after playback loads, including YouTube URLs opened directly in mpv and resolved stream URLs when mpv still exposes the original YouTube playlist entry. It creates text fields immediately, queues audio/image work for mined notes, and fills those fields once the local cache file is ready.
 
 Background cache downloads are capped at 720p by default (`youtube.mediaCache.maxHeight`; set `0` for unlimited) and use IPv4 and retry flags to reduce YouTube throttling failures. If the background download still fails, SubMiner shows a cache failure notification, shows queued-card failure notifications, and clears those pending updates so cards are not left waiting silently.

 **Supported formats:**
 
 - SRT/VTT: Regex-based parsing of timing lines + text content between timing blocks.
-- ASS: Parse `[Events]` section, extract `Dialogue:` lines, read the field order from the `Format:` row, and take everything after the Text field index as the text (Text can itself contain commas).
+- ASS: Parse the `[Events]` section, read the field order from the `Format:` row, and extract timed `Dialogue:` lines. Timed `Comment:` lines are normally ignored, but can supply canonical authored text when they match a nearby generated animation from the same style and actor. Text can itself contain commas.
 
 **ASS decoding.** The parser is where ASS text is decoded, once, via `assToPlainText()` in `src/core/services/ass-text.ts`. That decoder mirrors mpv's `ass_to_plaintext` so a cue read from a file reads identically to the same line arriving live on `sub-text`: `{...}` override blocks are markup, `\pN … \p0` vector drawing runs are dropped rather than shown as text, `\N`/`\n`/`\h` are the only escapes (`\{`, `\}` and `\\` are not), and an unclosed `{` is rendered verbatim. Every layer downstream — renderer, timing tracker, tokenizer, tokenization cache keys — receives plain text and uses `normalizePlainSubtitleText()` for whitespace only, so nothing decodes the same string twice and one authored line always maps to one cache key.
 
 **Duplicate collapsing.** Typeset scripts emit one `Dialogue:` event per animation frame, plus layered copies of the same line. The parser collapses identical text over an identical span unconditionally, and collapses contiguous same-text runs of at least three events when the run looks like an animation. For ASS that means shared style and actor plus authoring evidence: a temporal tag (`\t`, `\move`, `\k`/`\kf`/`\ko`/`\K`, or anything wrapped in `\t(...)`), an animated `Effect` column (`Karaoke`, `Banner`, `Scroll`), or override values that change across the run. Static tags shared by every event (`\pos`, an identical `\clip`) are not evidence. SRT/VTT carry no such metadata, so there collapsing needs at least five contiguous events all under 0.1s — the frame timing left behind by ASS-to-SRT conversion. The parser keeps this authoring metadata (style, actor, layer, `Effect`, parsed override commands, source order) private; `parseSubtitleCues()` returns only `SubtitleCue`.
 
+ASS scripts can also redraw one complete lyric for two or more long color/highlight phases. Those flush-timed phases collapse separately from short animation frames when they share text, style, actor, and layer and carry direct animation evidence, such as temporal tags or changing non-spatial overrides. Spatial command changes do not prove a phase, so separately positioned signs remain distinct.
+
+**Canonical animation recovery.** Some ASS producers keep the readable lyric or sign as a timed `Comment:` and generate hundreds of `Dialogue:` frames containing repeated glyphs or changing clip regions. Others retain the complete line as brief `Dialogue:` events around the generated fragments. A complete event is promoted only when nearby dialogue from the same style and actor forms a proven animation cluster and reconstructs its entire text in source order. The generated frames are then replaced by one cue marked `source: 'canonical-ass'`. This source marker lets the live primary-subtitle path prefer the clean authored text and timing for display, sidebar history, immersion recording, and mining, while unmatched editor notes and alternative translations remain ignored. Secondary selection advances to an entering canonical cue at its generated animation start when the preceding authored cue ends before the new authored span. Unrelated simultaneous cues that continue through the new span remain visible.
+
+**Font texture cleanup.** A clipped repeated-glyph run or frequent changes to secondary alpha marks a texture seed. Clipped runs do not need a font override because some signs build their masks from ordinary `l` glyphs. The parser removes short clipped pieces that share a no-font seed's style and timing, or pieces that share a font seed's style, timing, and font even when the actor changes. It also removes positioned text layers with at least `E0` global alpha when they overlap a seed in the same style. Opaque authored sign text stays publishable when the texture switches fonts or actors around it.

 ## Live Cue Delivery
 
+- Primary live text first resolves recovered canonical ASS animations. Otherwise, when
+  every live mpv line matches an active parsed cue, it uses the parsed cue text so exact
+  full-span style layers appear once instead of repeating for fill, border, blur, shadow,
+  or equivalent whitespace variants. Any unmatched live line keeps the complete live
+  stack, preserving dialogue or signs that overlap a lyric.
 - A tokenization cache miss emits the plain cue synchronously. Tokenization remains serialized so
   live work does not contend for Yomitan state.
+- The initial `time-pos`, explicit renderer seeks, and later seek-like jumps reprocess mpv's
+  current raw `sub-text` after the new playback time is stored. Explicit intent matters because
+  adjacent subtitle jumps can be shorter than the general seek-distance threshold. This corrects
+  ASS cleanup when mpv delivered the destination subtitle before the destination timestamp.
+- Renderer `sub-seek` commands use the active parsed cue list when available. Simultaneous cues
+  share one boundary, overlapping lyrics advance from the latest active boundary, and mpv's native
+  command remains the fallback when no parsed destination exists. This prevents generated karaoke
+  frames from consuming next/previous subtitle presses.
+- Subtitle sidebar selections seek past the preceding sanitized cue's overlapping exit span when
+  the selected cue has enough time remaining. This keeps direct row selection on the requested
+  karaoke line while clamping the seek inside that cue.
+- If startup paints raw text before embedded ASS parsing finishes, parsed cue arrival may replace
+  that provisional line. The one-prime-per-media guard still suppresses identical repeats.
 - If a newer cue arrives while an older line is still tokenizing, the newer plain cue or empty
   clear payload is emitted immediately. The older tokenization result is dropped before it can
   replace the current cue.
 - The current cue upgrades in place when its tokens and annotations are ready. This can reflow text
   or character images, but cue visibility does not wait for that work.
 
+## Secondary Subtitle Flow
+
+- `secondary-sub-text` remains the immediate fallback, so unreadable subtitle sources, remote URLs,
+  and still-extracting embedded tracks appear without waiting for file resolution. Embedded-track
+  extraction runs for local and network-mounted files alike (demuxing reads the whole container,
+  about 10 seconds per GB on gigabit, under a generous timeout); only true remote URLs skip it,
+  having no on-disk container to demux.
+- The live fallback also suppresses per-glyph typesetting walls: when many simultaneous
+  one-glyph lines are present (generated karaoke lettering flattened into live text), those
+  lines and their short syllable companions are dropped while concurrent dialogue lines stay.
+  This keeps the overlay clean while extraction is still in flight and for sources that never
+  produce parsed cues.
+- Parsed secondary text and the live fallback remove exact repeated lines at any length. A
+  flattened-line identity also removes long dialogue/sign repetitions that differ only in
+  whitespace or terminal punctuation, while distinct simultaneous short lines remain separate.
+- `secondary-subtitle-track.ts` resolves `secondary-sid` against mpv's track list. External tracks
+  are read directly; supported embedded text tracks are extracted through the same ffmpeg-backed
+  source resolver used by primary subtitle prefetching.
+- The selected source is parsed with `parseSubtitleCues()`, including metadata-aware ASS duplicate
+  and animation collapse. Playback `time-pos` selects the active parsed cue after applying
+  `secondary-sub-delay`.
+- Fragment reconstruction marks tall multi-row positioned parts as a grid only when they read
+  like tiling: a couple of texts repeated across many fragments, the same text re-shown at one
+  spot over time (countdown/animation frames), or scattered single glyphs. Secondary text omits
+  those grids instead of flattening a translated table or schedule into one synthetic line.
+  Wrapped lyric rows, CC-style dialogue blocks, and reconstructed single-line karaoke remain
+  eligible for display.
+- The resolved text is stored in `mpvClient.currentSecondarySubText` before it is broadcast. The
+  overlay, mining, timing tracker, and immersion statistics therefore consume the same secondary
+  text when a readable source is available.
+- Simultaneous parsed cues use whitespace-insensitive identity, so ASS layers that vary only
+  between ordinary, hard, or ideographic spaces appear once.
+- Simultaneous ASS lines are flattened in top-to-bottom positioned order, falling back to their
+  authored source order when no usable position exists.
+- Half-size kana positioned directly above a same-timed kanji caption is treated as ASS
+  furigana. The parser omits it from published cues but retains hidden matching metadata so
+  mpv's raw live text can be reconciled without displaying or mining the reading. The
+  timing tracker (clipboard copy, recent-line mining) and immersion recorders run the same
+  reconciliation on the `sub-start`/`sub-end` sample, so they record what the overlay shows.
+- Broadcast-caption rows that spell one utterance across several same-timed positioned events
+  (same style, layer, and vertical band, stacked at most two text rows apart) are joined into
+  one cue with a single line break, so `preserveLineBreaks` treats them like an authored `\N`,
+  and the recorders above see the whole sentence. A row continues the one above it when that row
+  is a bare speaker label, ends without terminal punctuation, or leaves a ≪…≫ / ⸨…⸩ span open; a
+  lower row that opens its own label or span always starts a new cue, which keeps two speakers
+  sharing the screen on separate lines. The pass runs only on scripts that read as broadcast
+  captions (a meaningful share of events carry speaker labels or ≪…≫ / ⸨…⸩ spans) and only on
+  rows containing Japanese, because fansub typesetting stacks positioned rows for signs, chat
+  bubbles, and headlines where that punctuation convention does not hold.
+- Fragment-only ASS karaoke is reconstructed per style before publication. Explicit spaces
+  survive concatenation. Latin fragment typesetting with no literal spaces also recovers word
+  boundaries represented only by materially larger horizontal `\pos` or `\move` gaps within that
+  line. Unpositioned fragments stay compact instead of gaining guessed spaces between syllables.
+  Short runs qualify only when overlapping positioned events also show changing overrides or
+  repeated layer copies; an English or romaji style name alone never turns ordinary dialogue into
+  a lyric.
+- Recovered canonical ASS text remains active for the generated animation envelope. For
+  reconstructed lyric styles, the longest-lived active line wins over brief entrance and exit
+  fragments from the same style.
+- Media and `secondary-sid` changes clear the previous parsed state before refreshing the source;

 ## 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.
+- Library Merge & Reassignment
+  - Duplicate library cards for the same show can be combined: select entries in "Select" mode and use "Merge Selected" to combine their sessions, mined cards, and watch time onto one card.
+  - Episodes can be moved to a different entry with a per-episode "→" button, fixing stray files that split off their own entry; manual assignments now survive later filename parsing, Jellyfin refreshes, and season repair.
+  - Exact AniList matches with compatible seasons merge automatically, while likely (fuzzy) matches surface as a dismissible "Possible duplicate" suggestion instead of merging silently.
 
-- **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.
+- Duplicate Line Cleanup
+  - The Vocabulary tab's new **Duplicates** button scans a chosen time window for the repeated-line bursts described under Fixed below and collapses each burst to a single line once confirmed.
+  - A matching `subminer stats cleanup --duplicate-lines` command (with `--dry-run` and `--lookback-days <n>`) is available from the terminal.
+  - Only the affected subtitle lines and the vocabulary counts they inflated are touched; watch time and lines-seen totals are left as recorded.
 
 ### Fixed
 
-- **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.
+- Subtitle Duplication from Karaoke & Animated Signs
+  - Typeset ASS karaoke and animated signs no longer flood the overlay, subtitle sidebar, immersion history, mined cards, or stats with repeated glyph fragments or per-frame duplicates; the complete authored line is recovered instead, without merging genuinely repeated dialogue or separately positioned signs.
+  - Fragmented karaoke now preserves the spaces the author placed between words instead of joining them together, and lyric transitions (including seeking into the middle of a line) resolve to the clean line instead of a stray entrance or exit frame.
+  - The secondary overlay shares the same deduplication logic as the primary overlay, including collapsing lines that differ only by whitespace or trailing punctuation, and sidebar navigation moves between clean lyric lines while keeping the right line selected.
 
-- **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.
+- Anki Media Generation
+  - Sentence-audio generation no longer times out on slow network-mounted video files with many subtitle and font streams, and a failed extraction now reports a clear error instead of a raw `ENOENT`.
+  - Mined audio and animated AVIF clips now capture the subtitle line you actually mined, instead of whatever line happened to be on screen once slow audio extraction finished.
 
-- **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.
+- Character Dictionary Performance & Notifications
+  - Character dictionary generation, merged rebuilds, and imports no longer freeze the app on large dictionaries, and cached results (including character portraits) are reused across launches instead of regenerating everything every time.
+  - Portraits also now display correctly if their cache finishes loading after subtitles have already started showing.
+  - Desktop progress notifications, including on Linux AppImage installs, now update in place instead of flickering closed and reopening.
 
-- **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`.
+- Overlay Reliability
+  - Overlay modals (settings, stats, etc.) now open promptly on the first shortcut press, including on repeated sessions on Windows, and appear above fullscreen mpv on macOS instead of switching Spaces or opening off-screen.
+  - The macOS window-tracking helper is now built for macOS 12.0+, so the overlay attaches to mpv on older systems like Ventura instead of crashing and getting stuck on "Overlay loading."
+  - The overlay no longer gets stuck on "Overlay loading" indefinitely if mpv's connection stalls; it now retries and shows an actionable error after 30 seconds.
+  - Fixed native Wayland drag-and-drop from file managers like Thunar, and fixed system-wide mouse lag on Windows caused by the overlay's click-through handling.
 
-- **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 Dashboard
+  - Deletes, library merges, video moves, and AniList reassignments no longer freeze the stats dashboard or rebuild lifetime totals from scratch; large deletes that used to take minutes now finish in milliseconds.
+  - Vocabulary totals and charts now count all tracked vocabulary instead of just the first page, and new-word history uses corrected daily rollups.
+  - Calendar labels respect time zones west of UTC, and vocabulary cards refresh automatically after editing the word exclusion list (with a Retry option if a load fails).
 
-- **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.
+- Linux Launcher Thumbnails
+  - Fixed missing MKV thumbnails in the Linux rofi picker when the system thumbnailer only registers legacy Matroska MIME aliases.
