What
When copying files into the synced working directory, Claude now checks the destination and every parent directory it would create against your ignore rules, and fails with the error code WORKING_DEST_IGNORED rather than writing there.
Details
Sits alongside the existing checks for escaping the parent directory and for symlinked destinations.
Evidence
dest ancestor resolves into an ignored path
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
