Sync now now runs Backfill (resumes from the watermark, so a widened history horizon is picked up automatically) then IncrementalSync then detail-fill, in one click. "Full backfill" is gone -- in its place, "Reset all" (styled as a destructive action, gated by a confirm dialog) wipes every synced activity and its laps/kind assignments and rewinds the backfill watermark, so the next sync performs a genuinely fresh pull instead of trying to patch up existing rows with newer schema fields.
