GRUT-RAI: Grand Responsive Universe Theory - Responsive AI Engine (Phase II)

GRUT-RAI (GRUT Responsive AI) — Reference Implementation (v12) We are developing the Grand Responsive Universe Theory (GRUT). This repository provides the reference implementation for GRUT-RAI: a reproducible computation stack supporting the GRUT Phase I "Closure Protocol". What it is GRUT-RAI is intentionally split into three roles: Engine (grut-core/): deterministic physics routines (no generative AI). Auditor (nis/): generates a Numerical Integrity Standard (NIS) certificate (hashes, tolerances, provenance). Narrator (rai-orchestrator/): optional interface layer that explains certified outputs; forbidden from generating numerical results. Golden rule: the AI narrates; the engine calculates; the NIS certifies. How to cite Cite the Zenodo DOI for this specific release (Version DOI) for reproducibility. Relationship to the manuscript This software implements and certifies the computations described in: "GRUT Phase I: The Closure Protocol — A Causal, Screened Metric-Response Framework for Dark Sector Phenomenology" (see Related Identifiers for the manuscript DOI).
