stat file %q: %w

Error message

stat file %q: %w

What it means

os.Lstat on the joined path failed — the file reported as changed (e.g. untracked) no longer exists or cannot be stat'ed. Common when the working tree is modified between git listing the file and reading it, or on permission problems.

Solutions

1. Check the wrapped error: ENOENT means the file was deleted between diff collection and read; EACCES means permission is missing
2. Refresh the file list (re-run git status) if the working tree changed concurrently
3. Ensure the process has read permission for the file
