Hosting versus Deriving the Born Rule in Registration Theory: A Conditional Theorem, Native Quadratic Invariants, and Obstructions
This status report asks whether Registration Theory (RT) derives the qubit Born rule, P(+) = cos²φ, from its own deterministic registration dynamics, or only hosts a construction that reproduces it. RT's canonical finite model is the four-node adaptive consequence-registration field (ACRF-4).Main results:A conditional...
