What
When a file arriving from the other side differs from one you changed locally, the sync writes the incoming content to a sibling file named with "Claude's conflicted copy" plus a YYYY-MM-DD date, leaving your version untouched.
Details
- If that name is taken it appends a counter, trying up to 100 candidates.
- The base name is truncated so the final file name stays within 255 minus 32 bytes, and candidates that are invalid on Windows are rejected.
- If no usable name is found the operation is reported as failed instead of clobbering the local file.
- Applies only on remote worker sessions, under the same environment gate as the syncer.

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