# GEOX Earth Witness

**GEOX** is the Earth Witness organ in the arifOS constitutional federation. It serves as the reality gatekeeper for geoscience operations, ensuring that AI reasoning outputs are physically possible, geospatially grounded, and consistent with world-state evidence.

## The Problem Solved

Plain LLMs optimize for plausibility, not physical truth. They can hallucinate elegant but impossible geological interpretations. GEOX anchors AI in deterministic physics and spatial reality, while arifOS governs what that grounded system is allowed to claim.

## Core Features

- **Forward vs Inverse Modelling**: GEOX acts as the laboratory to stress-test structural hypotheses generated by reasoning organs (like @RIF) against real constraints.
- **Theory of Anomalous Contrast (ToAC)**: Prevents AI from being fooled by display artifacts by enforcing multi-model candidates and bias audits.
- **RATLAS (Reference Atlas of Earth Materials)**: A physics-backed material intelligence layer containing 99 canonical Earth material states for symbolic grounding.

## 13 Floors in GEOX

GEOX rigorously enforces arifOS constitutional floors:

- **F1 (Amanah)**: All interpretations are revisable; irreversible claims trigger an 888_HOLD.
- **F2 (Truth)**: Claims must be grounded in evidence with uncertainty bands declared.
- **F4 (Clarity)**: Scale, CRS, and provenance must be explicitly stated.
