What
A file named with a dotless i, a long s, a Kelvin sign or an ff/fi ligature no longer slips past the checks that classify a path as sensitive. Paths are normalised through a NFKD plus case round trip with invisible characters stripped, and tracked sensitive files get their own verdict, sensitive_tracked. The sync worker's filename-safety checks reject these look-alikes outright.
Details
The set of confusables differs by platform: Windows and WSL use one list, macOS adds ß.
Runs on every classification, with no flag.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
