-- Fixed words being highlighted green as known when a same-spelled Anki card taught a different reading (e.g. とこ parsed as 床 "bed" matching a known 床/ゆか "floor" card). The known-word cache now stores each card's word together with its reading and only matches when the token's reading agrees; cards without a reading field keep matching in any reading as before.
+- New reading-aware subtitle parsing and known-word matching: the known-word cache now stores each Anki card's word together with its reading (cache format v3), and a token only gets the known-word highlight when its parsed reading agrees with the card. The cache and the stats server upgrade automatically.
+- Fixes words being highlighted green as known when a same-spelled Anki card taught a different reading (e.g. とこ parsed as 床 "bed" no longer matches a known 床/ゆか "floor" card). Cards without a reading field keep matching in any reading as before.
+- Single-kana grammar tokens (よ in 全然いいよ, standalone え) no longer borrow the reading of an unrelated card (such as 夜 or 絵) and get painted as known: reading-only matching requires at least two kana, while single-kana cards still match by their word field.

-- Fixed single-kana grammar tokens counting as known words by borrowing the reading of an unrelated Anki note (よ in 全然いいよ matched a card read よ such as 夜, standalone え matched 絵), which painted them with the known-word highlight. Reading-only known-word matching now requires at least two kana; single-kana cards still match by their word field, and tokens genuinely present in the known-words cache (e.g. です) keep their highlight.
 - Standalone suffix tokens (MeCab pos2 接尾, e.g. さん, れる) are now excluded from JLPT/frequency/N+1 annotations by default, matching how particles and interjections are treated. Cache-backed known-word highlighting still applies; override via the pos2 exclusion config if you want them annotated.

-- Session known-word counts no longer show 0 everywhere. The stats server's known-word cache parser only understood the v1/v2 cache formats, so after the reading-aware v3 cache upgrade it silently treated the cache as missing; it now flattens v3 note entries into the headword set.

-- Fixed subtitle text that Yomitan's parser cannot match (e.g. the truncated volitional in とこ戻ろ…) being rendered as plain, non-interactive text: it was invisible to hover/lookup and excluded from the n+1 word count, which could wrongly mark a sentence as n+1. Unparsed runs are now kept as hoverable tokens matching Yomitan's own segmentation; bracketed SFX/speaker captions and punctuation-only runs are still skipped.
+- Fixed subtitle text that Yomitan's parser cannot match (truncated inflections like the volitional in とこ戻ろ…, elongation runs like ぅ～/ぉ〜) being rendered as plain, non-interactive text with no hover lookup. Unparsed runs are now kept as hoverable tokens matching Yomitan's own segmentation, while being fully ignored by frequency/JLPT highlighting, the N+1 candidate math, and vocabulary stats. Bracketed SFX/speaker captions and punctuation-only runs are still skipped.
