Recommended action: Replace the symlink with a real directory, move the symlink outside writable roots, or add the real target path to config explicitly. Option: Replace the symlink with a real directory, move the symlink outside writable roots, or add the real target path to config explicitly. [evidence: official_recommended_action] Applies when: Running commands in workspace-write where a protected/read-only subpath is reached through a symlink inside a writable root Steps: 1. Identify the symlink named in the error (ls -l) 2. Replace it with the real directory or point config at the resolved path 3. Avoid symlinked .git/.codex dirs inside writable roots Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
