Incoming files with names Windows or WSL cannot handle are skipped instead of breaking the sync.
What's wrong with this entry?
Incoming file lists are now validated and filtered before anything is written, so names that cannot exist safely on Windows or WSL are dropped rather than causing failures mid-apply.
- A malformed, oversized, wrong-side or wrong-version list is rejected outright (
oversize,unsupported_version,malformed,wrong_side). - Paths that look like internal sync paths are dropped.
- On Windows and WSL each path segment is cut at the first colon and stripped of trailing dots and spaces, then rejected if it matches an old-style 8.3 short name pattern.
- Dropped paths are counted separately and reported as filtered files in the sync telemetry.
- Conflicted-copy naming separately rejects reserved Windows device names (con, prn, aux, nul, com, lpt).
unsupported_version
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
