An automated process dumps all the new audio files downloaded into a common flat folder and asks Kodi to scan it via the JSON-RPC API. The documentation notes that the library update process "only actually scans the tags from those files that are new or changed" but what I have noticed in the logs is that irrespective of any modified time on the files, every audio file in the folder is removed from the library and rescanned.

Code:

Looking at the database, I see strHash only recorded at folder level and it leads me to believe that this is how audio scanning is supposed to work. Is my understanding wrong, the documentation outdated, LE-flavored-Kodi somehow breaking things, or JSON-RPC's AudioLibrary.Scan not capable of checking for changes at the file level?
