III.T01 — Non-Emptiness Theorem

Each enrichment layer E_k (k = 0,1,2,3) is inhabited: it contains genuine objects and morphisms. Constructive witnesses: E₀ = any τ-object with NF address, E₁ = H_τ-enriched Hom spaces, E₂ = proto-codes from BSD carriers (preview), E₃ = self-modeling codes (preview).
