Chronos + χ: A Minimal Implementation Guide for Stability-Regulated Evolution

This paper provides a short, practical implementation guide for using the Chronos dynamical time-field extension of canonical quantum gravity and applying the Chronos stability constant χ as a universal stability regulator. The guide is designed for reproducibility and direct adoption by the physics community, focusing on a minimal “drop-in” procedure that restores explicit evolution to Wheeler–DeWitt-type wavefunctionals while preserving canonical constraint structure. It includes (i) the minimal objects and definitions needed to implement a dynamical scalar time field Θ(x), (ii) the Chronos evolution equation and the equilibrium recovery of the standard frozen Wheeler–DeWitt constraint, (iii) a concise explanation of χ as a stability-selected, dimensionless coupling scale (treated effectively in this guide), and (iv) verification checks and two minimal worked toy examples illustrating both Schrödinger-type evolution in Θ and χ-based regulation between collapse-dominant and blow-up-dominant regimes. This document is intended to function as a practical “user manual” companion to the broader Chronos + χ research program.
