This document is Vol.2.2 of the Re-Phase series. It updates and formalizes the terminology of Re-Phase by replacing the earlier hidden-state vocabulary with a configuration-based framework. The document defines configuration space, configuration, compatible set, admissible set, compatibility relation, refinement, unfolding, and structural reconstruction. The purpose of this volume is to provide a stable conceptual coordinate system for later Re-Phase volumes. It also explains how earlier terms such as hidden state, observation map, fiber, admissible state, and collapse should be interpreted in the revised terminology. Re-Phase studies how observations, local interactions, and compatibility constraints restrict a configuration space, leaving admissible configurations from which structure can be reconstructed or unfolded.
