Chapter 5: SelfDesc: The Internal Decoding Loop

The SelfDesc predicate requires that an internal evaluator Eval_X reconstructs the distinction D_n from code(D)[ω] and NF_n(x). The evaluator is internal—it operates within X, not from an external vantage. This separates Life from mere physical stability: once SelfDesc is achieved, the system’s distinction is self-maintaining and perturbations within the basin are corrected.
