Live watching is now event-driven, no tree polling: - Android: MainActivity registers a MediaStore ContentObserver (Images, notifyForDescendants) and wakes the Rust watcher thread via a JNI call (Java_wow_gmp_gallery_MainActivity_nativeFsChange) — a single channel send, no main-thread work. Covers camera saves, media-scanner indexing, other apps' indexed writes. - Desktop: inotify/FSEvents via notify on the scan roots. - On wake: coalesce + debounce, diff dir mtimes, rescan only the changed subtrees. The 1 s recv timeout doubles as a cheap backstop (raw out-of-band copies the scanner hasn't indexed yet); a 5-minute full pass is the safety net. minSdk 30 (3-arg ContentObserver API). Stale-listing truncation bug found and fixed (reproduced on the emulator's 9p /sdcard; the phone's FUSE does the same): a readdir over a large directory can return a SILENT early EOF — a stale cached listing with NO error. The phone's 9961-file Camera dir truncated at ~8400 once and db::apply deleted ~1700 good rows. Three layers now: 1. scan::read_dir_full — retry whole-dir reads on mid-stream errors; 2. per-directory cross-check in walk_dir: if the enumeration is far below the DB's count for that dir, re-read up to 3x keeping the best listing; whole-walk re-check in rescan keeps the larger of two walks; 3. db::apply mass-delete guard: never delete >20% of the DB in one apply unless a previous walk already saw the low count (two-strike; a meta.walked row tracks it). Genuine gradual deletions still flow through (verified: a 4000-file mass move streams the grid down progressively), and a second consecutive low walk still deletes. Emulator reliability suite (all pass): 3x launch count stability, add +1 / remove -1 in ~2 s, 20-file burst, DB recovery from damage, stale-listing refusal (0 rows lost), two-strike delete, live restore, idle 0.0% dropped frames, deep fling loads thumbnails. A/B vs ttimg (no-backend CSS-scroll control): adb-swipe drop deltas are at the input-injection artifact level, idle identical (0.0%).
