What
When directory sync clears a repository folder, it moves the contents aside (.git first) and leaves a file called FILE_SYNC_STOPPED.md at the root explaining what happened, listing anything it could not move.
Details
- Each listed name is sanitised and truncated to 120 characters with an ellipsis.
- Failures are recorded as telemetry: unlisted entries, rename failures and marker-write failures, plus read/write failures for the persisted record.
- That record tracks a phase of clearing, cleared or untouched.
- Whether this runs at all depends on directory sync being active for your session.
Evidence
These entries could not be moved and are still here:
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
