The In Silico Abstraction Note

This addendum formally transposes the Hydra-Flux Cyber-Physical State Machine from the management of physical continuous media to the computational domain (in silico). It translates the established asynchronous exception grammar into a probabilistic pruning heuristic and constraint-resolution engine for Digital Twins and THMC solvers. By dynamically eliminating mathematically non-viable simulation pathways based on strict physical invariants, this architecture optimizes computational efficiency.
