Three bugs fixed: 1. catchupScan used raw dir.walk() with no filters, causing hidden/excluded files to appear as "new" every startup and trigger a catchup sync. Fixed by using LocalAccessor.walkFiles(pair) which applies the same filters and uses the same mtime source (SAF cursor) as SyncEngine. 2. catchupScan compared localModifiedAt.toEpochMilli() vs File.lastModified() (millisecond precision) while SyncEngine uses second precision. Every file appeared "modified" after a successful sync. Fixed by using epochSecond. 3. syncDecide() treated !localExists && remoteExists && known==null as "user deleted local copy → delete remote" even on files that were never synced. Fixed to treat unknown remote files as new (download them), which is safe because a genuinely-deleted file will always have a known state record from the previous sync.
