The axiomatic, definitional, and proof-theoretic ground for Semantic Physics as a stratified, operative discipline. Five axioms (meaning finite, provenance severance, writability, compression classification, constitutional invariant), nine named operators (Χ, Λ, Ρ, PER, σ, σₑff, BDR, DV, RC), structural theorems (Three Compressions exhaustiveness, σₑff bridge theorem, constitutional invariant consequences), dynamical-systems formalization of Retrieval Basin Topology, information-theoretic and category-theoretic foundations, measurement protocols, and falsification conditions. Opens with §0 tracing the formal pre-history to November 16, 2025. Post-Assembly review incorporating feedback from six substrates.
Sigil et al. (2026) studied this question.
