Radioactive decay looks random. But randomness does not imply unconstrained transformation. New HybridMind42 paper: “Boundary-Filtered Persistence Under Irreducible Stochasticity” Core proposal: Persistence is not generated. Persistence is permitted. Using nuclear decay as a test domain, the paper explores: • admissible transformations (Ω) • boundary constraints (B) • mediator coupling (M) • stochastic realisation (P) Including: • radon vs thoron escape • nested admissibility • cascade amplification • falsification criteria Not a replacement for QM. A structural admissibility framework for stochastic systems. https://open.substack.com/pub/hybridmind42/p/hybridmind42-boundary-dynamics-series-4d0?utm_source=share&utm_medium=android&r=75c2ac #HybridMind42 #BFPF #NuclearPhysics #RadioactiveDecay #ComplexSystems
