Coherence Geometry: Curvature-Driven Amplitude Relaxation Canon (CGI-CDR-05), v1.0

This canon records the coherence–geometric interpretation of curvature-driven amplitude relaxation (CDAR) as a physical organizing mechanism underlying diffusion–reaction–like pattern formation and spatial structure. It fixes scope, terminology, canonical claims, and representative field equations, positioning classical diffusion, reaction, and band-selection behavior as projected or limiting descriptions of a more structured coherence–geometric relaxation substrate. This document is a provenance and scope record and intentionally omits full derivations and implementations; referenced technical artifacts are tracked via SHA-256 hash commitments included in the release package.
