Backend-Neutral Explainable Geometry State and Operators R package XGeoRTR version 0.7.0 Provides the platform layer for explanation geometry in R. The package standardizes generic explanation tables into a normalized backend state object, computes embeddings, diagnostics, and multiscale level-of-detail summaries, and serializes backend-neutral state for reproducible workflows. It also exposes selected long-table and regular-grid views for downstream use-case packages. Rendering and viewport orchestration are delegated to downstream frontends such as 'ggWebGL'.
