When Claude Code runs in the cloud, a background worker copies changes from your own machine's project folder across to the cloud copy (directory sync). If that worker's read is refused as unauthorized, or because the sync channel is unavailable, it now sends Claude a one-time note. The note says newer changes from your machine may not be arriving and that this turn works from the files already there. It also records an event named tengu_dir_sync_git_worker_lane_refusing.
If the sync channel has worked earlier in the session, these refusals no longer make the worker stop for good.
Claude is no longer left assuming it sees your newest edits when sync has quietly stopped delivering them, and a temporary refusal no longer shuts down sync for the rest of the session.
