What
A folder snapshot is a copy of a folder that Claude Code prepares and uploads. It can now fail with a new reason, folder_too_large. When it does, usage reporting includes the folder's size in bytes as folder_bytes. Separately, a case named seed was removed from an internal list of pinned items.
Why
A folder that is too big now has its own named failure, instead of being counted under another reason.

The writer flagged doubt
The finding does not say what the size limit is, what the snapshot is used for, or whether you see this reason on screen.
