## Summary This is an alternative to `--require-hashes` which will validate a hash if it's present, but ignore requirements that omit hashes or are absent from the lockfile entirely. So, e.g., transitive dependencies that are missing will _not_ error; nor will dependencies that are included but lack a hash. Closes https://github.com/astral-sh/uv/issues/3305.
