When Claude Code copies a project's files to a remote machine for the first time, or keeps a folder in sync with one, it ends with a "Left on this machine" summary. That summary lists files it did not send, grouped by reason. It now has a new category, configuration_linked, for files held back because they are linked from your Claude Code configuration. Configuration here means the settings files that control how Claude Code behaves.
Why
You can now see how many files stayed behind for this reason instead of wondering why they are missing on the remote side.
