Method Folder
Folder(string, string, bool, string?)
FILESYSTEM PATHS ONLY. Ordinal-sorted; document ids are forward-slashed paths relative to the root. This is the desktop and app-private-storage shape — see spec 11.3 for mobile.

Remarks
A sub-directory that is a symbolic link or a junction is not entered: a link can point back up the tree, which is a walk that does not end, or out of it, which is documents nobody chose to index. The root itself may be a link, and a symbolic link to a FILE is still read - its id is the link's path and its content the target's.
A sub-directory that cannot be listed is skipped and logged (event 923), and the run goes on. Documents already indexed from it are kept rather than pruned, because not being able to look is not evidence that they are gone.
Exceptions
- EdgeIngestionException
6051 when the root is missing or unreadable — raised here, before any document, because a run over a folder that is not there is meaningless. 6055 for an empty source id.
