What
A linked git worktree is an extra working folder attached to an existing git repository. Folder trust is the approval you give before Claude Code works in a folder. For linked worktrees, Claude Code now checks that the folder holding the trust record for that worktree is the one it should be.
If it is a different folder, the check fails and the result is treated as possibly tampered with.
If that folder cannot be found, the check fails with "the folder that keeps this tree’s trust could not be resolved".
Why
This makes worktree trust harder to fool, so a worktree cannot borrow trust that belongs somewhere else.
