 ## Acceptance Criteria
 <!-- AC:BEGIN -->
-- [ ] #1 Add an opt-in setting/feature flag for N+1 highlighting and default it to disabled for backward-compatible behavior.
-- [ ] #2 Implement a one-time import/sync that queries known-word data from Anki into a local store on first enable or explicit refresh.
-- [ ] #3 Store known words locally in an efficient structure for fast lookup during subtitle rendering.
-- [ ] #4 Run periodic refresh on a configurable interval and expose a manual refresh action.
-- [ ] #5 Ensure local cache updates replace or merge safely without corrupting in-flight subtitle rendering queries.
-- [ ] #6 Known/unknown lookup decisions are applied consistently to subtitle tokens for highlighting without impacting tokenization performance.
-- [ ] #7 Non-targeted words remain visually unchanged and all existing subtitle interactions remain unaffected.
-- [ ] #8 Add tests/validation for initial sync success, refresh update, and disabled-mode no-lookup behavior.
-- [ ] #9 Document Anki data source expectations, failure handling, and update policy/interval behavior.
-- [ ] #10 If full Anki query integration is not possible in this environment, define deterministic fallback behavior with clear user-visible messaging.

+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Implemented in refactor via merge from task-24-known-word-refresh (commits 854b8fb, e8f2431, ed5a249). Includes manual/periodic known-word cache refresh, opt-in N+1 highlighting path, cache persistence behavior, CLI refresh command, and related tests/docs updates.
+<!-- SECTION:FINAL_SUMMARY:END -->

 ## Definition of Done
 <!-- DOD:BEGIN -->
-- [ ] #1 N+1 known-word highlighting is configurable, performs local cached lookups, and is demonstrated to update correctly after periodic/manual refresh.
