v1.7.0: full-reliability Fast mode (batch default), player scroll fix, fluke closure

[DynamycSound]

Fast mode: reliability restored, promoted to batch

Live-probe diagnosis of the latest "no lyrics found" screenshots: most of those songs ARE on LRCLib, synced ("Ili Ili" by Seksi, "Peta Brzina" by Vlada Matovic, "TMM TMM" by Summer Cem) — but the user ran fast mode, which truncated the provider list to the top 2, so the provider that has them never ran (rows show only QQ/Netease tried). Since providers already race in parallel, truncation bought ~nothing and cost real matches.

• MatchConfig.fast() now keeps all enabled providers and the full candidate ladder; speed comes from tight retry/timeout budgets + the early auto-accept stop.
• New batchFastMode setting (default on), surfaced at the top of batch download options labeled Recommended; batch runs now use the fast config when enabled.

Player: the real "stuck at first line" bug

val currentIndex by remember { derivedStateOf { ... lines ... } } — unkeyed remember captured the initially-empty lines list forever when lyrics load asynchronously (the from-Home path added with the issue-#11 fix), so the highlight and the auto-scroll never moved for the whole song. Now remember(lines). Also:

• Enhanced-LRC word stamps (<00:40.49>) are stripped from displayed text (they were rendered raw), and lines carrying only word stamps now parse using the first word stamp as line time.
• Same stamp-stripping in the result-screen preview.

Batch impostor guard (the "200" fluke)

"200" (Ourmoney) got Russian lyrics from a same-length "200" by Tveth/Sevnz/Лора — the exact-runtime escape let a disagreeing artist through and the cover second-opinion was advisory only. In batch (which saves unattended), a hit or rescue or plain-fallback whose artist agrees with none of the file's artist readings now requires positive cover-art confirmation, else it's skipped. The single-song screen keeps the escape since the user visually judges results there. The correct "200" exists on LRCLib as plain lyrics and is reachable via the unsynced fallback.

Cross-script matching

Serbian/Russian Cyrillic → Latin transliteration in normalizeForCompare (aligned with diacritic stripping: ж→z like ž→z): "Секси" == "Seksi". Cyrillic-indexed provider entries stop counting as strangers; genuinely different Cyrillic acts still disagree.

Query recovery

Double quotes (straight + smart) stripped from titles: Summer Cem - "TMM TMM" now reaches providers (LRCLib has it synced ×3).

Providers investigated, honestly

Verified live: QQ indexes the missing Serbian songs (Prazan Disko, Volim Pare — exact ids found) but its lyric backend returns empty for them (sanity-checked working on Shape of You); Genius is Cloudflare-blocked with no usable tokenless API; tekstovi.net has no machine-readable search. No new provider is added because none would deliver lyrics — recovery comes from the fixes above. Songs absent from every catalogue keep failing honestly.

Version

1.6.4 (164) → 1.7.0 (170).

Testing

• 2 new tests (quoted titles, Cyrillic transliteration + "200" disagreement) in MessyNameRecoveryTest — pass.
• Full matching suite green except pre-existing live-network SuicideboysMatchTest.loot (fails on unmodified master).
• :app:compileDebugKotlin clean.
• Live catalogue probes for every recovery claim (LRCLib/QQ/Deezer/iTunes/paxsenix).
