RCD 2.0 Paper 0 — Constitution, Governance and Recentering Roadmap Radial Coherential Dynamics — New Stage Foundational

RCD 2.0 designates the recentering, governance, and multiscale-closure phase of the Radial Coherential Dynamics (RCD) program. This document, Paper 0, serves as its constitutional framework. It does not introduce new phenomenology; instead, it fixes the formal architecture of the program, classifies the full corpus by epistemic status, and converts the next stage of development into an executable mathematical roadmap. The document has three functions. First, it states the unifying principle of RCD: a coherential field C(x,t) whose dynamics underlie the program's cosmological, galactic, gravitational, and quantum sectors. Second, it establishes a governance taxonomy with four operational levels — derived core,…
