The write path learned to say which file the server refused; the drain path —
the one that runs for work queued while offline — still reported only a count.
That is the path that matters most, because everything it carries was made
with no connection and exists on one device.
With it named, the failure on the tablet is:
draining PhotosRaw/2026/2026-08-03/_MG_9221.drsc:
permission denied
on a credential that pushes the catalog to the same library root in the same
pass. So this is not the account and not the app password: one path is
writable and another is not, which points at the server — a read-only share
over that folder, or a file access control rule on the extension — rather than
at anything this side can retry its way out of.
