What
Claude Code has a new subsystem that builds and reuses a private, admin-only git directory for a working tree. It now detects when a tree's .git directory has been moved, replaced, turned into a symlink, or points at object stores it doesn't own, and refuses to run git commands against that tree when this kind of tampering is found.
Why
This protects against git operations running against a working tree whose git metadata has been unexpectedly altered or swapped out, which could otherwise lead to operating on the wrong data without warning.
