No Posner-Molecule Nuclear-Spin-Qubit Decoherence Sources Found in Search — E8 Intelligence Research

FINDING: Search returned no Posner-molecule / nuclear-spin-qubit decoherence sources; results are unrelated (cavitation LES, silicon spin qubits, ML potentials, HDBSCAN, DIS). | MATH: No Ca₉(PO₄)₆ data present. Reference values for the actual Posner system (from literature, not these sources): cage point-group symmetry T_d (tetrahedral, 24 elements); ⁹P nuclear spin I = 1/2; six equivalent phosphate P sites → 6-spin-1/2 register; singlet (S=0) lifetime τ ≈ 10⁵ s in isolation, dropping to ~10⁻⁵–10⁻³ s under physiological decoherence; hyperfine coupling A(³¹P) ~ 10²–10³ Hz scale. | CONNECTION: T_d tetrahedral cage = root system A₃; 6 vertices map to octahedral coordination of the 6 PO₄ groups about the central Ca — octahedral group O_h ⊃ T_d; no φ-ratios (0.618 etc.) supported by evidence. | DEPTH: 1 (search failed to retrieve relevant sources; no mathematical content to extract). --- Note: The retrieved items do not address the query.
