read file %q: %w

Error message

read file %q: %w

What it means

Final os.ReadFile on the resolved, containment-checked path failed — permission denied, file deleted in a race, or an I/O error. All safety checks passed; this is a plain read failure wrapped with the repo-relative path and OS error.

Solutions

2. Verify the file exists and is readable by the current user
3. If the working tree changed mid-review, refresh the change list and retry
