The Quantum Structure Sub-Programme

The quantum structure sub-programme of the Cosmochrony corpus addresses a single central question: how does the admissible SU (2) sector force the structures of quantum mechanics, without importing quantum postulates? Starting from the admissibility constraints of A1–A4 on the binary icosahedral group 2I and the Weil representation V_, the sub-programme derives: phase coherence of the admissible fibre (Q1) ; the singlet correlator E (a, b) = -a (Q1, Q3) ; the Tsirelson bound |S₂₇ₒ₇| 22 (Q1) ; the Born rule in the SU (2) sector (Q1, Q3) ; the identification of SU (2) as the unique stable fixed point of the admissibility flow (Q2) ; the universal spin-j generalisation of all the above for all five admissible sectors j \1{2, 1, 32, 2, 52\} of 2I (Q3) ; and the structural non-applicability of Bell factorizability in non-injective frameworks (Bell paper). All these results are proved within the SU (2) sector. Extension to arbitrary observables, multipartite systems, and continuous spectra remains the primary open deliverable.
