What
When syncing a cloud or background session's files, Claude Code now recognizes a lane_full response from the server (shown internally as file_store_full) and displays a clear message telling you the session's cloud file store is full, explaining that Claude will keep working on your machine directly. This joins other existing sync failure reasons like refused, too_large, and withdrawn, and falls back to local-only operation the same way those do.
Why
This gives a clearer, specific explanation when a cloud session can't sync because its upload capacity is full, instead of a generic failure, while still letting work continue locally.
