- Persist vocabulary_visible on imm_words and filter rollups/triggers by it, matching the totals' exclusion rules
- Normalize legacy second/millisecond timestamps when bucketing rollup rows into local days
- Replace the boolean rollup-ready flag with a version key so schema changes trigger an atomic rebuild
- Preserve queued playback writes during rollup backfill instead of dropping them under queue pressure
- Time out the lexical rollup worker instead of hanging forever on no response
- Key concurrent vocabulary summary requests by their known-words snapshot so they no longer share stale state
- Bound stats dashboard retries for unfinished vocabulary loads before showing the inline Retry control
- Refetch vocabulary summary/charts once the exclusion list write is server-acknowledged, and retry failed aggregate loads with backoff before showing an inline error with a Retry control
- Coalesce concurrent getVocabularySummary calls into a single worker task
- Scan imm_words in id-keyed batches to bound memory for large vocabularies
- Add TsukiHime and AniSkip to feature table; note xz dependency
- Clarify Anki+AnkiConnect is required to mine, not to run
- Rework Windows setup with winget/scoop commands and PATH steps
- Note ffmpeg has no path-override setting, unlike mpv
- Fix screenshot alt text and installation.md anchor link
- Generate config.example.jsonc with a Linux socket path instead of Windows, so the example stays reproducible across platforms
- Document TsukiHime config (`tsukihime.*`), maturity-based known-word highlighting keys, and other config surfaces missing from the reference
- Correct secondary-subtitle auto-load defaults and Anki field-matching (case-insensitive) claims
- Expand Windows installation guide with winget/Scoop package tables and manual PATH setup
- Add docs-site/links.test.ts to catch broken internal links and heading-anchor mismatches
- Fix stale cross-references in jimaku-integration.md and demos.md
- Extract buildHistoryEntryActions to build the series action menu, now including a previous-episode option alongside replay/next/browse/quit
- Update docs and changelog entry to describe the new option
- Add tests covering previous/replay/next ordering and omission when last watched file is missing
- Merge the five separate sync change fragments (launcher command, UI window, close/quit fixes, active-session double-count, monthly rollup timezone) into a single changes/sync.md
- Fold kana-pos-content-classification.md into annotation-noise-rule-table.md
- Drop the now-stale Unreleased sections from CHANGELOG.md and docs-site/changelog.md
