🪴 O(1) Proof on Crambin (PDB: 1CRN): From FASTA to 3D Physical Reality

From 1D Sequences to 3D Physical Reality: The O(1) Experimental Proof on Crambin (PDB: 1CRN) 

While classical bioinformatics remains trapped in statistical approximations and GPU-heavy stochastic predictions (AlphaFold, ESMFold), the MSO Base-4 engine demonstrates that biological folding is a deterministic geometric resolution. Where our previous analysis exposed the failure of 1D cryptographic hashing (such as SHA-256 in the TEES Genome Passport), this benchmark moves directly into 3D space, proving that native structure is folded by spatial invariant constraints without entropic debt (E_debt = 0).
