pub fn fix_node_hashes(spec_dir: &Path) -> Result<FixReport, Error>Expand description
Fix node-side hashes by recomputing C14N hash from current spec content.
Assembles the combined document, finds each referenced spec node,
serializes it, applies inclusive C14N via bergshamra, and computes
SHA-256. Updates node-hash attributes on <art:spec-ref> in-place.
