Notes
Theoretical Advances
The v2.0 framework establishes several exact mathematical relations previously unavailable:
- N_gen = 3 from topological necessity (rank-Weyl structure)
- Triple origin for √17 (Higgs sector)
- Binary architecture foundation for dark energy
- McKay correspondence connection to golden ratio
Experimental Outlook
The framework now provides clear falsification criteria and testable predictions for upcoming experiments (Belle II, LHCb, precision neutrino measurements). The tightest constraint comes from δ_CP, where future precision measurements could decisively test the topological origin hypothesis.
