Real frames on a real backbone

Real frames, real backbone

Real ubiquitin (1UBQ), residues 1–20. Each frame — rotation and position — is computed live from actual N, Cα, C atoms, the same construction IPA uses. Step through how a single attention score gets built.

residue 1 — frame + query point residue 10 — frame + key point Q–K distance
