- native_root(): pick app root by presence of gps_live/gps_points files.
app_data_dir() is the root directly on this Tauri; the old .parent().parent()
read the wrong dir, so background (screen-off) points were never imported.
- recoverFromFiles: match file->session by id/date, plus session id stamped
into the native file name (gps_points_<ms>_s<id>.jsonl) for exact binding
(gps_set_session_id -> Kotlin bindSessionIfPending). Proximity dedup +-2.5s,
recalc with noDelete (never runs the destructive glitch/>24h filter that
once wiped real rides), delete already-imported files. Progress bar UI.
- bike kcal is NET (daily balance already books BMR*activityLevel): pedaling =
max(physics power/efficiency, MET-net by speed), coasting (power<=0, the bike
would roll unpowered) = basal only. Elevation via cumulative hysteresis.
recomputeAllStats + "recompute elevation/kcal" menu refresh stored tracks
without touching points.
- live recording: the native file is the DB source of truth; watchPosition
only drives the live marker, so a fix is not stored twice with two timestamps.
- track list pagination, SAF local-file picker, tile regions from router.
