resolve file %q: %w

Error message

resolve file %q: %w

What it means

filepath.EvalSymlinks failed while resolving the file itself (after parent checks passed), or the resolved file — a regular path whose final component is a symlink target — fell outside the repo. Prevents a symlink inside the repo from pointing at a file outside it and having its contents read into the diff.

Solutions

1. Check the wrapped error for why EvalSymlinks failed (typically a broken symlink to a nonexistent target)
2. Repair or remove the broken symlink
3. If the target exists outside the repo, the subsequent WithinBase check will reject it — that is expected
