OP8 — Empirical Universality and Validation Theory of Constructibility

OP8 is the empirical universality and validation layer of the Constructibility program. OP6b established a spatial Landau–Ginzburg field theory of constructibility degradation; OP7 developed the non-equilibrium survival theory with hazard exponent ψh = νz ≈ 1.166 and conjectural lifetime exponent ψT = ν2z ≈ 0.680. OP8 now asks: can these exponents be measured, and do they agree across domains? We formalize the observable dictionary mapping latent theory quantities to domain-specific proxies, state the cross-domain universality class hypothesis, and develop the full validation protocol: finite-size scaling (FSS) data collapse estimators, collapse quality metrics, model comparison (likelihood ratio, AIC/BIC, Bayes factor), and explicit falsifiability criteria. Domain-specific experimental programs are specified for LLM architectures, clinical cohorts (n > 50K), seismic networks, and cyber systems. OP8 is deliberately agnostic about which universality class the data will reveal: the program is designed to test, not confirm, the OP6b–OP7 predictions.
