Folder trust checks now use the git repository root and flag unsafe paths

Before Claude Code works in a folder, it checks whether you have marked that folder as trusted. If you have not, it asks you first. That check used to look at a single directory. It now also uses the root of the git repository (the top folder of the project's version history) and applies a rule for paths it considers unsafe.

The check now reports four things:

• trusted: whether the location counts as trusted
• directory: the folder that was checked
• unsafe_path: whether the path was judged unsafe
• root: the root folder used for the check
