chore(release): 0.15.0-beta.12

- Prompt now requests short top-level bullets with nested change/benefit/action sub-bullets in release-notes mode
- CHANGELOG mode keeps single-line bullets unchanged
- Tests assert new prompt constraints are present

changes/README.md

@@ -35,6 +35,7 @@ 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.
 - `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.

 - Fixed Kiku duplicate-card detection so local duplicate sentence cards trigger the manual modal or auto merge, modal-open acknowledgement races no longer cancel the flow, and merged fields follow Kiku's group ordering, sentence-audio, furigana, and tag semantics.
 - Fixed manual clipboard card updates from YouTube playback so generated audio and images use mpv's resolved stream URLs instead of the YouTube page URL.
 - Sentence cards now refresh the current secondary subtitle before saving, so the translation field uses the loaded subtitle instead of repeating the primary text.

Entries are scoped to the current AniList media and generate Japanese name aliases only, so raw romanized or English aliases no longer appear as separate results. The in-app AniList title selector now waits for an explicit search rather than triggering automatically; the search box is prefilled from the current filename guess.

 ### Fixed

Passthrough is fixed so mpv controls stay clickable before hovering a subtitle bar. The overlay stays stable when clicking from the overlay back into mpv. Background tracking overhead is reduced while mpv is stably focused.

+  - Settings windows (SubMiner and Yomitan) now open above the subtitle overlay; the overlay hides immediately when the character dictionary modal opens, including while AniList lookup is in progress.
 
-- **Jellyfin Playback:** Resolved a wide range of Jellyfin discovery and playback issues: the active item is no longer reloaded during startup, paused mpv is no longer misreported as playing, startup unpause no longer repeats after a manual pause or `y-t` toggle, duplicate ready signals no longer re-show the overlay, and long-lived sidebar ffmpeg extractors no longer run against stream URLs. Discovery now correctly handles delayed Japanese subtitle selection and prevents later-loading foreign tracks from stealing the active Japanese track. Discovery resume correctly handles `StartPositionTicks: 0` for items with saved progress.

+  - Discovery resume correctly handles `StartPositionTicks: 0` for items with saved progress.
 
-- **Jellyfin Subtitles:** Improved subtitle timing by preferring default embedded streams over external sidecars, stripping Jellyfin's server-selected stream from playback URLs, suppressing mpv auto-selection while SubMiner stages managed tracks, and automatically correcting clear Japanese-vs-English cue timeline offsets. Per-stream subtitle delay shifts are restored on load. Track selection now tolerates transient `track-list` read failures and numeric string track IDs on Linux.

-- **Jellyfin Overlay:** The visible subtitle overlay now shows automatically during Jellyfin playback so `subtitleStyle` appearance applies. The bundled mpv plugin is injected when SubMiner auto-launches mpv for Jellyfin so mpv-side keybindings work without overlay focus. The `y-t` overlay toggle is reliable and remains sticky across stream redirects. Passive Linux/Hyprland overlay shows no longer steal keyboard focus from mpv.

-- **Jellyfin Remote Progress:** Fixed progress sync for mpv/SubMiner seek jumps, stopped sessions, startup path changes, and Linux websocket reconnect windows. Play and Resume are now distinct: Play starts from the beginning while Resume starts at the saved position. Final progress reports use SubMiner's last known position when mpv resets during stop.

+- **Jellyfin Setup:** Fixed the Windows login flow with an IPC bridge and immediate progress feedback; unreachable servers time out with an inline error instead of hanging.
 
-- **Subtitle Sync Modal:** Fixed a macOS issue where opening the subtitle sync modal would flash and disappear on the first attempt, or leave stale state after syncing.
+- **AniList Progress:** Threshold checks now use fresh playback position data so updates fire correctly when playback reaches or skips past the watched threshold.
+  - Season-specific results are preferred for multi-season files, with a clear message when the matched season is not in Planning or Watching status.
+  - Repeated missing-token checks no longer exhaust AniList retry attempts or create duplicate dead-letter entries for the same episode.
 
-- **Controller:** Controller config and debug shortcuts now stay closed while controller support is disabled, with a notice to enable `controller.enabled`. Learn mode can be entered from the edit pencil or binding badge, remaps are saved per controller profile, and individual bindings can be reset to their defaults.
+- **Anki:** Sentence-audio padding is now opt-in by default; animated AVIF freeze-frame duration is correctly aligned to word audio length without double-counting padding.
+  - Multi-line sentence mining stays aligned for repeated subtitle text; Kiku duplicate-card detection and merge flow are fixed; clipboard card updates from YouTube use mpv's resolved stream URLs; sentence cards refresh the secondary subtitle before saving.
+  - Known-word cache append is fixed when no default Anki mining deck is configured but multiple known-word deck field mappings are present.

Season-specific results are preferred for multi-season files, and a clear message is shown when the matched season is not in Planning or Watching status. Repeated missing-token checks no longer rapidly exhaust AniList retry attempts or create duplicate dead-letter entries for the same episode.
+- **YouTube:** Primary subtitles are downloaded to temporary local files so the primary bar and sidebar read the same source, with cleanup on reload and quit.
+  - False load-failure notifications are suppressed. Launcher-managed playback creates the tray icon when attaching to an already-running process, and app-owned playback no longer lets the mpv plugin start a second SubMiner instance.

When padding is configured, animated AVIF freeze-frame duration is correctly aligned to the word audio length without double-counting sentence audio padding. Multi-line sentence mining stays aligned when repeated subtitle text appears in the selected history range. Manual clipboard card updates from YouTube playback now use mpv's resolved stream URLs for generated audio and images. Sentence cards now refresh the current secondary subtitle before saving so the translation field contains the loaded subtitle rather than repeating the primary text. Kiku duplicate-card detection correctly groups fields, modal-open acknowledgement races no longer cancel the merge flow, and merged fields follow Kiku's group ordering, sentence-audio, furigana, and tag semantics.
+- **Character Dictionary:** Surname honorifics are now matched for Japanese localized aliases embedded in AniList alternative names; cached snapshots are regenerated to include them.
+  - Cached media matches are reused when loading a title with an existing snapshot, avoiding redundant AniList search requests. Manager keyboard shortcuts are correctly forwarded to the mpv plugin.

False subtitle load failure notifications are suppressed after SubMiner confirms the selected track loaded. Launcher-managed playback commands create the tray icon even when attaching to an already-running process, and app-owned YouTube playback no longer lets the mpv plugin start a second SubMiner instance.
+- **Updater:** Update checks are more stable across platforms: Linux uses GitHub release metadata; `subminer -u` can update independently of the tray app; macOS update dialogs reliably appear in the foreground.
+  - Builds that cannot apply native updates show a manual-install message instead of a restart prompt. Windows retains the native NSIS update path while routing updater HTTP through the main process.

Character dictionary manager keyboard shortcuts are now correctly forwarded to the mpv plugin.
+- **Setup - macOS:** First-run setup recognizes existing `subminer` installs in Homebrew or user PATH directories and avoids writing into Homebrew-owned paths.

+- **Tray App:** Fixed several lifecycle issues: the tray stays running when Yomitan settings are closed; a close-only menu prevents accidentally quitting the tray app; an in-page close button is available on Hyprland where native window controls are unavailable.
+  - Settings loading no longer blocks other tray actions; the embedded popup preview is disabled to prevent renderer hangs during sidebar navigation; extension refreshes at startup are serialized; the session help modal closes correctly without mpv running.

-
+  - `subminer settings` on macOS no longer emits Electron menu diagnostics and exits cleanly when the window is closed. Linux first-run launcher installs build with a valid Bun shebang; `subminer app` on Linux returns control to the terminal immediately.

On Windows, managed mpv launches from a background SubMiner instance correctly retarget the new mpv socket, bind to the player window, and receive startup overlay options.
 
 - **Playback:** The first subtitle is primed before autoplay resumes so the overlay renders text before video playback begins. Launcher-owned videos quit SubMiner when playback ends while background and tray sessions stay alive.
+  - The visible overlay and subtitle stream stay alive after restarting SubMiner from the `y-r` shortcut, with correct Linux bounds reapplication and user-paused playback preserved through readiness gates.
 
-- **Subtitle Frequency:** Frequency highlighting is preserved for determiner-led noun compounds like `その場` while standalone determiners are still filtered. Frequency annotations are also corrected for Yomitan single-token compounds with internal particles such as `目の前`, while pure grammar and kana helper spans remain unannotated.
+- **Subtitle Frequency:** Frequency highlighting is preserved for determiner-led noun compounds like `その場` while standalone determiners are still filtered. Annotations are corrected for Yomitan single-token compounds with internal particles like `目の前`.
 
-- **Shortcuts:** Native mpv menu shortcuts are disabled during managed macOS playback so configured SubMiner shortcuts also work while mpv has focus. Session shortcuts including `stats.markWatchedKey` are correctly wired through mpv. The visible overlay receives focus when entering multi-line copy/mine selection so number keys work on macOS and Windows.
+- **Subtitle Annotation Prefetch:** Cached annotations and character images are ready for more live subtitle changes without delaying raw subtitle display.

Learn mode can be entered from the edit pencil or binding badge; remaps are saved per controller profile, and individual bindings can be reset to their defaults.
 
 - **Discord Rich Presence:** Presence no longer falls back to Jellyfin stream URLs; Jellyfin playback titles are primed before loading tokenized streams so presence shows the show/episode title.
 
 - **WebSocket:** The regular subtitle WebSocket now sends plain text only; annotation spans and token metadata are sent exclusively on the annotation WebSocket.
 
-- **Windows:** Startup failures now show a native error dialog and write fatal details to the app log instead of exiting silently.
+- **Windows Startup:** Fatal startup errors now show a native error dialog and write details to the app log instead of exiting silently.
 
-- **Yomitan:** Fixed Yomitan popups not opening when overlay startup races the Yomitan extension load.
+- **Yomitan:** Fixed popups not opening when overlay startup races the Yomitan extension load.
 
-- **Settings:** Search now works across all categories, narrows correctly on multi-word terms, and hides settings with dedicated editors. Live saves for subtitle CSS declarations apply immediately to open overlays. Legacy subtitle appearance options and hover token colors are automatically migrated into `subtitleStyle.css`. The note-fields note type picker defaults to the configured Anki deck's note type, then `Kiku`, then `Lapis`, leaving it blank for manual selection otherwise. User config files are preserved during legacy config compatibility handling. The generated example config uses the same CSS declaration paths written by the Settings window.
+- **Subtitle Sync Modal:** Fixed a macOS issue where the modal would flash and disappear on the first attempt, or leave stale state after syncing.
 
 ### Docs
 
-- **Versioned Docs:** Stable docs are now published at the site root with current development docs under `/main/`. Fixed versioned docs navigation so archived pages keep local links under the selected version, the version switcher no longer nests paths incorrectly, local dev version routes serve warmed archive files instead of redirecting to production, and internal README files no longer break archived builds.

+  - Fixed versioned docs navigation so archived pages keep local links under the selected version, the version switcher no longer nests paths incorrectly, and local dev version routes serve warmed archive files instead of redirecting to production.
 
 - **Configuration Reference:** All previously undocumented config options are now covered, including `subtitleStyle.primaryDefaultMode`, `stats.markWatchedKey`, `immersionTracking.lifetimeSummaries.*`, and all seven `mpv.*` launcher options. Updated known-word cache docs and examples to recommend expression/word fields.
 
-- **Architecture Docs:** Added a Playback Startup Flow diagram showing how managed launches inject the plugin, establish the IPC socket, and bring up the overlay via the two convergent triggers. Added a Runtime Sockets section and diagram to the IPC + Runtime Contracts page, with cross-reference pointers in the MPV Plugin and Troubleshooting pages.
