Information Weight and Effective Gravitational Coupling in a Finite WRRA Model: Response sufficiency and stability under finite address restrictions

A finite WRRA response-information study. Explicit preparations preserve the inherited weighted carrier snapshot yet have different load susceptibilities. The manuscript distinguishes joint and clamped equilibration, derives the positive-Hessian stability criterion, identifies sufficient load-class information, and states the condition for a scalar effective gravitational coupling. Version 0.3 adds a preparation comparison table, standalone carrier/load explanation, matrix interpretation and a proposed finite-lattice application. Includes executable reproduction materials and an internal Astra Medium review; not external peer review or journal acceptance. Absolute Newtonian normalization remains a calibration input.
