computed heavy-atom contacts from PDB file, 5 angstrom cutoff

Source-checked chain-role heuristic: short polypeptide chain as peptide, longer polypeptide chain as target.

PDB/RCSB public archive metadata with derived contact labels when computed.


pose retained as coordinate-reference-only; contact metrics exclude this subset
