Atmospheric composition follows the prime lattice — not planetary history
The dominant molecular species in Earth's atmosphere are selected by the {2,3,5} prime Tau-lattice. Oxygen (O₂ = 32 = 2⁵) is a pure binary node — the atmosphere's primary Tau-coupling agent. Argon (Ar = 40 = 2³×5) sits at the binary-quintic junction — structurally inert. Water (H₂O = 18 = 2×3²) is the binary-ternary mediator — the universal Tau-solvent.
Ratio N≡N / O=O: 945/498 = 1.8976 ≈ 2 × (7/2⁵)^(1/2) — boundary scaling
N₂ is inert because 7 is outside the lattice
O₂ = 2⁵. Pure binary Tau-lattice node. Primary atmospheric Tau-coupling agent. Combustion and respiration are Tau-strand coupling events.
Ar = 2³×5. Binary-quintic junction. Cannot couple to either pure binary or ternary flows — structurally noble by lattice position.
H₂O = 2×3². Binary-ternary junction — the universal Tau-mediator. Water's anomalous properties all derive from this dual-lattice coupling position.
Prediction: any G1-register habitable planet will show this three-tier atmosphere: boundary-prime buffer + pure-lattice reactive + junction-isolate noble gas.
