 SubMiner is an Electron overlay that sits on top of mpv. It turns your video player into a full sentence-mining workstation:
 
-- **Hover to look up** — Yomitan dictionary popups directly on subtitles
-- **Keyboard-driven lookup mode** — Navigate token-by-token, keep lookup open across tokens, and control popup scrolling/audio/mining without leaving the overlay
-- **One-key mining** — Creates Anki cards with sentence, audio, screenshot, and translation
-- **Instant auto-enrichment** — Optional local AnkiConnect proxy enriches new Yomitan cards immediately
-- **Reading annotations** — Combines N+1 targeting, frequency-dictionary highlighting, and JLPT underlining while you read
-- **Hover-aware playback** — By default, hovering subtitle text pauses mpv and resumes on mouse leave (`subtitleStyle.autoPauseVideoOnHover`)
-- **Subtitle tools** — Download from Jimaku, sync with alass/ffsubsync
-- **Immersion tracking** — SQLite-powered stats on your watch time and mining activity
-- **Custom texthooker page** — Built-in custom texthooker page and websocket, no extra setup
-- **Annotated websocket API** — Dedicated annotation feed can serve bundled texthooker or external clients with rendered `sentence` HTML plus structured `tokens`
-- **Jellyfin integration** — Remote playback setup, cast device mode, and direct playback launch
-- **AniList progress** — Track episode completion and push watching progress automatically
+- **Dictionary lookups** — Yomitan popups on subtitles with hover or full keyboard-driven navigation; hover-aware auto-pause keeps playback in sync
+- **One-key mining** — Creates Anki cards with sentence, audio, screenshot, and AI-powered translation
+- **Reading annotations** — N+1 targeting, frequency highlighting, and JLPT underlining while you watch
+- **Subtitle tools** — Jimaku downloads, alass/ffsubsync sync, and whisper.cpp transcription for YouTube with optional AI cleanup
+- **Texthooker** — Built-in texthooker page and annotated websocket API for external clients
+- **Immersion tracking** — SQLite-powered stats on watch time and mining activity
+- **Integrations** — Jellyfin remote playback, AniList episode progress, and AnkiConnect auto-enrichment

Bundled Yomitan is built natively with Bun from the `vendor/subminer-yomitan` submodule into `build/yomitan` during `bun run build`, so Bun is the only JS runtime/package manager required for source builds.

-## Testing
-
-- Run `bun run test` or `bun run test:fast` for the default fast lane: config/core coverage plus representative entry/runtime, Anki integration, and main runtime checks.
-- Run `bun run test:full` for the maintained test surface: Bun-compatible `src/**` coverage, Bun-compatible launcher unit coverage, and a Node compatibility lane for suites that depend on Electron named exports or `node:sqlite` behavior.
-- Run `bun run test:node:compat` directly when you only need the Node-backed compatibility slice: `ipc`, `anki-jimaku-ipc`, `overlay-manager`, `config-validation`, `startup-config`, and runtime registry coverage.
-- Run `bun run test:env` for environment-specific verification: launcher smoke/plugin checks plus the SQLite-backed immersion tracker lane.
-- Run `bun run test:immersion:sqlite` when you specifically need real SQLite persistence coverage under Node with `--experimental-sqlite`.
-- Run `bun run test:subtitle` for the maintained `alass`/`ffsubsync` subtitle surface.

-The Bun-managed discovery lanes intentionally exclude a small set of suites that are currently Node-only because of Bun runtime/tooling gaps rather than product behavior: Electron named-export tests in `src/core/services/ipc.test.ts`, `src/core/services/anki-jimaku-ipc.test.ts`, and `src/core/services/overlay-manager.test.ts`, plus runtime/config tests in `src/main/config-validation.test.ts`, `src/main/runtime/startup-config.test.ts`, and `src/main/runtime/registry.test.ts`. `bun run test:node:compat` keeps those suites in the standard workflow instead of leaving them untracked.
