-## Description

-<!-- SECTION:DESCRIPTION:BEGIN -->
-$Current YouTube subtitle generation in launcher/youtube.ts is functional but has implicit behavior, low observability, and unnecessary full-file work. This task modernizes the existing pipeline without changing core architecture.
-
-Scope:
-- Make track selection explicit (manual > auto > whisper per primary/secondary) with deterministic reasons.
-- Avoid running whisper/audio work when a track is already satisfied.
-- Add bounded execution for yt-dlp and whisper subprocesses.
-- Improve stage-level logging for both automatic and preprocess modes.
-- Make secondary track fallback decisions explicit and not implicit.
-- Preserve existing user behavior except where policy is clarified.
-
-Files expected:
-- launcher/youtube.ts
-- launcher/commands/playback-command.ts (if mode/status behavior requires)
-- launcher/types.ts (if schema updates needed)
-- launcher/config/args-normalizer.ts (if timeout/config options added)
-- launcher/util.ts (if runExternalCommand timeout controls added)
-- Add/update launcher subtitle-generation tests
-<!-- SECTION:DESCRIPTION:END -->
-
-## Acceptance Criteria
-<!-- AC:BEGIN -->
-- [ ] #1 Define deterministic track priority for each track: manual, then auto, then whisper (per track) and record source choice with reason.
-- [ ] #2 If manual or auto satisfies a track, skip whisper for that same track and avoid unrelated full extraction/transcription work.
-- [ ] #3 Introduce timeout or budget caps for yt-dlp and whisper calls; timeout should fail safe and unblock automatic playback.
-- [ ] #4 Emit explicit status logs at each stage: metadata load, manual sub fetch, auto sub fetch, whisper audio extraction, whisper run, publish/load, final success/failure summary.
-- [ ] #5 Make secondary handling explicit: transcribe target and translate target must only run when required by config and not by side-effect of primary logic.
-- [ ] #6 Keep preprocess and automatic modes stable in success paths while making behavior in failure paths explicit and bounded.
-- [ ] #7 Add tests for track-combination cases: primary available, secondary available, both missing, partial fallback, both missing with missing whisper config, timeout/error behavior.
-- [ ] #8 Document any behavior changes if user-visible, especially fallback order, timeout behavior, and fallback disablement.

+## Description

+<!-- SECTION:DESCRIPTION:BEGIN -->
+N+1 and frequency highlighting should ignore non-learning tokens (e.g., particles/auxiliary forms) based on MeCab POS1 tags, while remaining user-configurable.
+
+Problem example: for subtitle phrase containing になれば, the highlighted N+1 target should not be the non-useful inflection/token piece when POS indicates an excluded class.
+
+Implement configurable exclusion defaults with add/remove overrides so users can tune behavior without code changes.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Default exclusion set omits non-useful POS1 classes from both N+1 candidate selection and frequency highlighting.
+- [x] #2 Users can add extra POS1 exclusions and remove defaults via config.
+- [x] #3 Tokenizer/annotation tests cover default behavior and config add/remove overrides.
+<!-- AC:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Implemented configurable annotation POS exclusions with defaults+add/remove for both MeCab POS1 and POS2, wired to N+1 candidate selection and frequency highlighting. Added POS2 default exclusion (非自立), expanded POS1 defaults for function words, added Yomitan->MeCab enrichment to carry pos2/pos3 metadata, updated config docs/examples, and added regression tests including になれば case.

+Removed user-facing subtitleStyle.annotationFilters POS exclusion configuration (schema/resolver/options/docs/example).
