sudacode fa3051f9cb feat(subtitles): add regex subtitle filters with built-in presets (#318)
- Add `subtitleFilter` config with four presets: parentheses, brackets, speaker prefix and music symbols. Custom regex rules run after the presets.
- Filter primary text where it enters the app (live `sub-text` and parsed cues), so the overlay, sidebar, mining and stats all get the same filtered text.
- Changes hot-reload: the current line is read again and the active track is parsed again, using the filter config as the prefetch parse key.
- Add a custom rule editor in Settings under Behavior → Subtitle Filters that checks patterns as you type.
- Update the config example, the configuration docs and the architecture domains doc, and add a changelog fragment.

# Domain Ownership
Status: active
Last verified: 2026-10-31
Owner: Kyle Yasuda
Read when: you need to find the owner module for a behavior or test surface
## Runtime Domains
- Desktop app runtime: `src/main.ts`, `src/main/`, `src/core/services/`
- Overlay renderer: `src/renderer/`
- Launcher CLI: `launcher/`
- mpv plugin: `plugin/subminer/`
## Product / Integration Domains
- Config system: `src/config/`; Anki resolution is composed by
`src/config/resolve/anki-connect.ts` from focused resolvers in
`src/config/resolve/anki-connect/`
Config hot-reload and the settings window: `src/main/assemblies/settings.ts`
- App startup: app-ready sequence, headless known-word refresh, overlay startup prerequisites and
overlay runtime bootstrap: `src/main/assemblies/startup.ts`
- Overlay/window state: `src/core/services/overlay-*`, `src/main/overlay-*.ts`
Overlay windows, visibility, Linux fullscreen handling, and the overlay-window IPC handlers
(modal open/close, pointer interaction, content measurement): `src/main/assemblies/overlay.ts`
Overlay-hosted modal openers: `src/main/assemblies/overlay-modals.ts`
- MPV runtime and protocol: `src/core/services/mpv*.ts`
mpv client creation, mpv event wiring, AniSkip, subtitle prefetch, and subtitle sidebar state: `src/main/assemblies/playback.ts`
- Keyboard input outside the renderer (overlay, global and numeric shortcuts, session bindings):
`src/main/assemblies/shortcuts.ts`
- System tray: `src/main/assemblies/tray.ts`
- Yomitan/Hachidori extension loading, parser runtime deps, and dictionary settings windows:
`src/main/assemblies/yomitan.ts`
Windows executable lookup and detached process creation are shared in `src/main/runtime/mpv-process.ts`. The Windows launcher and Jellyfin handlers retain their own playback and connection workflows.
- Subtitle/token pipeline: `src/core/services/subtitle-*.ts`, `src/core/services/tokenizer*`, `src/core/services/tokenizer/`, `src/subsync/`
JLPT and frequency annotation lookups: `src/main/jlpt-runtime.ts`, `src/main/frequency-dictionary-runtime.ts`, assembled by `src/main/assemblies/dictionaries.ts`
Subtitle text filters (`subtitleFilter`): `src/shared/subtitle-text-filter.ts`. Primary text is filtered at its two entry points, live `sub-text` in `mpv-protocol.ts` and parsed cues in `playback.ts`, so every consumer sees the same text and live/cue matching still works. A config change re-reads `sub-text` and re-parses the active track (the prefetch controller's parse key).
- First-run setup: `src/main/runtime/first-run-setup-*.ts`, assembled by `src/main/assemblies/first-run-setup.ts`
- Anki workflow: `src/anki-integration/`, `src/core/services/anki-jimaku*.ts`
Card mining handlers, the pending lookup context, field grouping, and media timing review wiring:
`src/main/assemblies/mining.ts`
- Media timing review: `src/main/runtime/media-timing-review.ts` owns the review and hidden `MediaTimingPreviewSession`. The session waits for mpv readiness and acknowledges playback commands; its `time-pos` observations reach the modal through `media-timing-review:preview-position`. The renderer places the cursor from those timestamps and uses an inactivity timeout instead of timing the clip itself.
- Immersion tracking: `src/core/services/immersion-tracker/`; tracker startup, the stats server,
the stats overlay window options, and the `--stats` command are assembled by `src/main/assemblies/stats.ts`
Includes stats storage/query schema such as `imm_videos`, `imm_media_art`, and `imm_youtube_videos` for per-video and YouTube-specific library metadata.
Library-entry identity aliases and merge recommendations are persisted alongside this schema; the stats HTTP and SPA layers only expose and present those domain decisions.
`delete-maintenance-scheduler.ts` coalesces and serializes stats deletes; the expensive work runs in `delete-maintenance-worker-thread.ts` while the tracker queues playback writes. Each batch uses one transaction, lexical update, rollup refresh, and incremental lifetime subtraction (`planLifetimeRemovals`/`applyLifetimeRemovals` in `lifetime.ts`). Merges, moves, AniList reassignments, and `stats cleanup -l` use `repairLifetimeSummariesFromMedia` (recompute from the per-video media ledger). The full lifetime rebuild survives only as the empty-table bootstrap; anywhere else it would collapse lifetime totals to the session retention window.
- Immersion sync: `src/core/services/stats-sync/`, bound by `src/main/sync-cli.ts`. The sync window and auto-sync scheduler live in `src/main/assemblies/sync.ts`.
`snapshot-transfer.ts` selects compressed rsync or scp. `transfer-cache.ts` atomically retains the last successfully received snapshot per hashed peer/database identity under the config directory's `sync-transfer-cache/`. Cache copies seed isolated transfer directories; rsync verifies reconstructed files before the existing merge engine runs. The `--make-temp` / `--remove-temp` helpers accept an internal `--transfer-cache` key, with a fallback for older peers that do not recognize it.
- AniList tracking + character dictionary: `src/core/services/anilist/`, `src/main/runtime/composers/anilist-*` (called by `src/main/assemblies/anilist.ts`), `src/main/character-dictionary-runtime.ts`, `src/main/character-dictionary-runtime/`, assembled by `src/main/assemblies/character-dictionary.ts`
- TMDB live-action metadata: `src/core/services/tmdb/` (client + exact-title resolver), `src/core/services/immersion-tracker/live-action-link.ts` (links an entry to a TMDB title and merges other holders of the same title). The AniList cover-art fetcher calls the resolver as its fallback; `imm_anime.media_kind` marks the result and keeps the entry out of AniList season repair.
- Jellyfin integration: `src/core/services/jellyfin*.ts`, `src/main/runtime/composers/jellyfin-*`,
assembled by `src/main/assemblies/jellyfin.ts`
- YouTube playback, subtitles, media cache, and in-app browser: `src/core/services/youtube/`,
`src/main/runtime/youtube-*`, assembled by `src/main/assemblies/youtube.ts`
- User plugins: `src/core/services/plugins/` (host, `ctx`, `exec`), `src/main/runtime/plugin-panel-runtime.ts` (panel modal), `src/main/runtime/plugin-window-runtime.ts` (plugin windows), `src/renderer/modals/plugin-panel*.ts`; examples in `assets/plugins/`
- Window trackers: `src/window-trackers/`
- Stats HTTP app: `src/core/services/stats-server.ts`, with route groups and shared route support
in `src/core/services/stats-server/`
- Stats SPA: `stats/`
- Public docs site: `docs-site/`
## Shared Contract Entry Points
Automatic mpv keyboard discovery uses the `get-mpv-input-bindings` IPC request and
`MpvInputBindingsSnapshot` in `src/types/session-bindings.ts`.
`src/main/runtime/mpv-input-bindings.ts` queries the connected player and preserves
configured keys, including disabled entries. `src/shared/mpv-input-bindings.ts`
validates discovered keys and translates browser input. The renderer's
`handlers/mpv-input-forwarding.ts` keeps the session lookup, coalesces asynchronous
refreshes, and releases held keys on blur or disposal. Discovered `WHEEL_*` bindings forward
as `keypress <key> <notches>` (Chromium reports 120 px per notch), which matches mpv's own
precise-scroll scaling. `MBTN_*` buttons forward as held `keydown`/`keyup` when mpv binds the
button or its `_DBL` variant, so mpv synthesizes double-clicks itself. Configured keybindings and
the built-in right-click pause run first. Forwarding is the only way pointer input reaches mpv on
Hyprland, where the overlay cannot be made click-through. `handlers/keyboard.ts` runs
this fallback after SubMiner controls and refreshes on startup, a delayed startup
pass, focus, binding reload, and the `mpv-input-bindings:changed` event. Main sends
that event from `session-bindings-runtime.ts` when mpv's discovered key set changes,
including the first discovery after connecting, because the overlay often loads
before mpv connects and the compiled session bindings may not change. Discovery does not enter compiled session bindings,
the plugin artifact, persistent config, or session help.
The subtitle sidebar consumes parsed cues through `SubtitleSidebarSnapshot`. Its `sourceKey`
identifies the media and subtitle source so renderer selections are invalidated on source changes,
including changes whose cue text and timings are identical. While open, the sidebar polls the
cheap `SubtitleSidebarPlaybackState` (cached time, current line, `sourceKey`, `cuesRevision`; no
mpv round-trips) every 80 ms for active-cue tracking. It fetches the full snapshot, which resolves
the source over mpv IPC and carries every cue plus config, only on open, config reload, a
`sourceKey`/`cuesRevision` change, and a ~2 s fallback. Native selection and clean clipboard
serialization live in `src/renderer/modals/subtitle-sidebar-selection.ts`. Electron lets standard
Copy input reach the renderer, where sidebar selection takes priority over the live-subtitle binding.
The preload bridge writes selections through Electron's clipboard API so copying does not depend
on Chromium document focus or require activating the overlay window.

## Ownership Heuristics
- Runtime wiring or dependency setup: start in `src/main/`
- Business logic or service behavior: start in `src/core/services/`
- UI interaction or overlay DOM behavior: start in `src/renderer/`
- Command parsing or mpv launch flow: start in `launcher/`
- Shared contract changes: add or edit the narrowest `src/types/<domain>.ts` entrypoint; only touch `src/types.ts` for compatibility exports.
