State Locality Theory 2 — Part I: Structural Foundations (v.2) Locality as a Structure of Manifestation. Axioms and Consequences.

State Locality Theory 2 (SLT‑2) is a theoretical framework that develops a structural account of locality as a fundamental condition of manifestation. Part I establishes the structural foundations of the theory: the core axioms, the formal setting, and the basic consequences that follow from them. The work introduces the structural architecture underlying state locality, formulates the principles governing local manifestation, and derives the initial set of structural results that support the later parts of the theory. This document is the first part of a multi‑part series presenting SLT‑2 in a systematic and rigorous form. Version 2 updates the foundational layer of SLT‑2. Two elements previously stated as axioms are now proven theorems. A new principle, Global Structural Stability, completes the axiom set. Several structural quantities are now derived analytically from the four‑state tetrahedral configuration in C2. The hierarchy ceiling and the gravitational level are integrated into the framework. The Open Questions section is updated to reflect recent results. All changes are additive and preserve compatibility with Version 1.
