 Implemented `subtitleStyle.autoPauseVideoOnHover` with default `true`, wired through config defaults/resolution/types, renderer state/style, and mouse hover handlers. Added playback pause-state IPC (`getPlaybackPaused`) to avoid false resume when media was already paused. Added renderer hover behavior tests (including race/cancel case) and config/resolve tests. Updated config examples and docs (`README`, usage, shortcuts, mining workflow, configuration) to document default hover pause/resume behavior and disable path.
 
+Follow-up adjustments (2026-03-04):

+- Hover pause now resumes immediately when leaving subtitle text (no Yomitan-popup hover retention).
+- Added `subtitleStyle.autoPauseVideoOnYomitanPopup` (default `false`) to optionally keep playback paused while Yomitan popup is open, with auto-resume on close only when SubMiner initiated the popup pause.
+- Yomitan popup control keybinds added while popup is open: `J/K` scroll, `M` mine, `P` audio play, `[` previous audio variant, `]` next audio variant (within selected source).
+- Extension copy drift detection widened so popup runtime changes are reliably re-copied on launch (`popup.js`, `popup-main.js`, `display.js`, `display-audio.js`).

+
+Move AniSkip MAL/title-to-MAL lookup and intro payload resolution from mpv Lua to launcher Electron flow, while keeping mpv-side intro skip UX and chapter/chapter prompt behavior in plugin. Launcher should infer/analyze file metadata, fetch AniSkip payload when launching files, and pass resolved skip window via script options; plugin should trust launcher payload and fall back only when absent.
+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [x] #1 Launcher infers AniSkip metadata for file targets using existing guessit/fallback logic and performs AniSkip MAL + payload resolution during mpv startup.
+- [x] #2 Launcher injects script options containing resolved MAL id and intro window fields (or explicit lookup-failure status) into mpv startup.
+- [x] #3 Lua plugin consumes launcher-provided AniSkip intro data and skips all network lookups when payload is present.
+- [x] #4 Standalone mpv/plugin usage without launcher payload continues to function using existing async in-plugin lookup path.
+- [x] #5 Docs and defaults are updated to document new script-option contract.
+- [x] #6 Launcher tests cover payload generation contract and fallback behavior where metadata is unavailable.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+
+1. Add launcher-side AniSkip payload resolution helpers in launcher/aniskip-metadata.ts (MAL prefix lookup + AniSkip payload fetch + result normalization).
+2. Wire launcher/mpv.ts + buildSubminerScriptOpts to pass resolved AniSkip fields/mode in --script-opts for file playback.
+3. Update plugin/subminer/aniskip.lua plus options/state to consume injected payload: if intro_start/end present, apply immediately and skip network lookup; otherwise retain existing async behavior.
+4. Ensure fallback for standalone mpv usage remains intact for no-launcher/manual refresh.
+5. Add/update tests/docs/config references for new script-opt contract and edge cases.
+<!-- SECTION:PLAN:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Executed end-to-end migration so launcher resolves AniSkip title/MAL/payload before mpv start and injects it via --script-opts. Plugin now parses and consumes launcher payload (JSON/url/base64), applies OP intro from payload, tracks payload metadata in state, and keeps legacy async lookup path for non-launcher/absent payload playback. Added launcher config key aniskip_payload and updated launcher/aniskip-metadata tests for resolve/payload behavior and contract validation.

Follow-up fixes kept lookup open while moving between tokens, made popup-local `J/K` and `ArrowUp/ArrowDown` scroll work from overlay-owned focus with key repeat, skipped keyboard/token annotation flow for parser groups that have no dictionary-backed headword, and preserved paused playback when token navigation jumps across subtitle lines.

+
+Track the remediation work from the March 6, 2026 code review. The review found that the default test gate only exercises 53 of 241 test files, the dedicated subtitle test lane is a no-op, SQLite-backed immersion tracking tests are conditionally skipped in the standard Bun run, src/main.ts still contains a large dead-symbol backlog, several registry/pipeline modules appear unreferenced from live execution paths, and src/anki-integration.ts remains an oversized orchestration file. This parent task should coordinate a safe sequence: improve verification first, then remove dead code and continue decomposition with good test coverage in place.
+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [ ] #1 Child tasks are created for each remediation workstream with explicit dependencies and enough context for an isolated agent to execute them.
+- [ ] #2 The parent task records the recommended sequencing and parallelization strategy so replacement agents can resume without conversation history.
+- [ ] #3 Completion of the parent task leaves the repository with a materially more trustworthy test gate, less dead architecture, and clearer ownership boundaries for the main runtime and Anki integration surfaces.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+
+Recommended sequencing:
+
+1. Run TASK-87.1, TASK-87.2, TASK-87.3, and TASK-87.7 first. These are the safety-net and tooling tasks and can largely proceed in parallel.
+2. Start TASK-87.4 once TASK-87.1 lands so src/main.ts cleanup happens under a more trustworthy test matrix.
+3. Start TASK-87.5 after TASK-87.1 and TASK-87.2 so dead subsync/pipeline cleanup happens with stronger subtitle and runtime verification.
+4. Start TASK-87.6 after TASK-87.1 so Anki refactors happen with broader default coverage in place.
+5. Keep PRs focused: do not combine verification work with architectural cleanup unless a narrow dependency requires it.
+
+Parallelization guidance:
+
+- Wave 1 parallel: TASK-87.1, TASK-87.2, TASK-87.3, TASK-87.7
+- Wave 2 parallel: TASK-87.4, TASK-87.5, TASK-87.6
+
+Shared review context to restate in child tasks:
+
+- Standard test scripts currently reference only 53 unique test files out of 241 discovered test and type-test files under src/ and launcher/.
+- test:subtitle is currently a placeholder echo even though subtitle sync is a user-facing feature.
+- SQLite-backed immersion tracker tests are conditionally skipped in the standard Bun run.
+- src/main.ts trips many noUnusedLocals/noUnusedParameters diagnostics.
+- src/translators/index.ts, src/subsync/engines.ts, src/subtitle/pipeline.ts, src/tokenizers/index.ts, and src/token-mergers/index.ts appeared unreferenced during review and must be re-verified before deletion.

A local audit found 241 test/type-test files under src/ and launcher/, but only 53 unique files referenced by the standard package.json test scripts.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+
+SubMiner advertises subtitle syncing with alass and ffsubsync, but the dedicated test:subtitle command currently does not run any tests. There is already lower-level coverage in src/core/services/subsync.test.ts, but the test matrix and contributor-facing commands do not reflect that reality. This task should replace the no-op lane with real verification, align scripts with the existing subsync test surface, and make the user-facing docs honest about how subtitle sync is verified.
+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [ ] #1 The test:subtitle entrypoint runs real automated verification instead of echoing a placeholder message.
+- [ ] #2 The subtitle verification lane covers both alass and ffsubsync behavior, including at least one non-happy-path scenario relevant to current functionality.
+- [ ] #3 Contributor-facing documentation points to the real subtitle verification command and no longer implies a dedicated test lane exists when it does not.
+- [ ] #4 The resulting verification strategy integrates cleanly with the repository-wide test matrix without duplicating or hiding existing subsync coverage.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+
+1. Audit the existing subtitle-sync test surface, especially src/core/services/subsync.test.ts, and decide whether test:subtitle should reuse or regroup that coverage.
+2. Replace the placeholder script with a real automated command and keep the matrix legible alongside TASK-87.1 work.
+3. Update README or related docs so the advertised subtitle verification path matches reality.
+4. Verify both alass and ffsubsync behavior remain covered by the resulting lane.

+
+The immersion tracker is persistence-heavy, but its SQLite-backed tests are conditionally skipped in the standard Bun run when node:sqlite support is unavailable. That creates a blind spot around session finalization, telemetry persistence, and retention behavior. This task should establish a reliable automated verification path for the database-backed cases and make the prerequisite/runtime behavior explicit to contributors and CI.

   - You explicitly call `script-message subminer-aniskip-refresh`.
 - Lookups are asynchronous (no blocking `ps`/`curl` on `file-loaded`).
 - MAL/title resolution is cached for the current mpv session.
-- When launched via `subminer`, launcher runs `guessit` first (file targets) and passes title/season/episode to the plugin; fallback is filename-derived title.
+- When launched via `subminer`, launcher can pass `aniskip_payload` (pre-fetched AniSkip `skip-times` payload) and the plugin applies it directly without making API calls.
+- If the payload is absent or invalid, lookup falls back to title/MAL-based async fetch.
 - Install `guessit` for best detection quality (`python3 -m pip install --user guessit`).
 - If OP interval exists, plugin adds `AniSkip Intro Start` and `AniSkip Intro End` chapters.
 - At intro start, plugin shows an OSD hint for the first 3 seconds (`You can skip by pressing y-k` by default).

+Keyboard-driven mode draws a selection outline around the active token. Use `Ctrl/Cmd+Y` to open or close lookup for that token. While the popup is open, popup-local controls still work from the overlay (`J/K`, `ArrowUp/ArrowDown`, `M`, `P`, `[`, `]`) and focus is forced back to the overlay so token navigation can continue without clicking subtitle text again. Moving left/right past the start or end of the line jumps to the previous or next subtitle line and keeps playback paused if it was already paused.

+By default, hovering over subtitle text pauses mpv playback. Playback resumes as soon as the cursor leaves subtitle text. Set `subtitleStyle.autoPauseVideoOnHover` to `false` to disable this behavior.
+
+If you want playback to stay paused while a Yomitan popup is open, set `subtitleStyle.autoPauseVideoOnYomitanPopup` to `true`. When enabled, SubMiner auto-resumes on popup close only if SubMiner paused playback for that popup.
+
+Keyboard-driven lookup mode is available with fixed shortcuts: `Ctrl/Cmd+Shift+Y` toggles token-selection mode, `ArrowLeft/Right` (or `H/L`) moves the selected token, and `Ctrl/Cmd+Y` opens or closes lookup for that token.
+
+If the Yomitan popup is open, you can control it directly from the overlay without moving focus into the popup: `J/K` or `ArrowUp/ArrowDown` scroll definitions, `M` mines/adds the selected term, `P` plays term audio, `[` plays the previous available audio, and `]` plays the next available audio in the selected source. While lookup stays open, `ArrowLeft/Right` (or `H/L`) moves to the previous or next token and refreshes the definition for the new token. If you move past the start or end of the current subtitle line, SubMiner jumps to the previous or next subtitle line, moves the selector to the edge token on that line, and keeps playback paused if it was already paused.
