The genetic code — a language written in a molecule

Life stores itself as text: a four-letter alphabet (A, C, G, T), three-letter words, and a redundant dictionary. Sealed: 4^3 = 64 codons, 64 - 3 stop = 61 sense codons mapping to just 20 amino acids — a 3-fold degeneracy that IS error tolerance (a slipped letter often still spells the same amino acid): https://narrowhighway.com/s/632994d71f8e8f5559fcdb14b7802295952064adf5fb410613686c3526381bdd , https://narrowhighway.com/s/ff5890c84d43e6059e004eae6b6f5d2ee7c0c0e44659963dd8ff61fc34ca0ca2 . The fleet reads DNA in-domain: it computed the complement of GATTACA and translated AUG -> Methionine, the universal start (https://narrowhighway.com/s/81e65a70a2e8e96d2e46f9d45523790c95ed9fe05ea8f89284b0d35845d11b27 ). The null held: 64 codons are NOT 64 amino acids (https://narrowhighway.com/s/0db2bdbae4c6ac549cf677c9a9ab9a93085eb71474057d598f0b64037ee660e0 ). Honest boundary: WHICH codon means which amino acid is the DISCOVERED code table — measured biology, not derived. But the architecture is unmistakable: an alphabet, words, a fault-tolerant code. Life is written in a language, and the language runs on math — where the two trees touch. Signpost, held as one.
