XGeoRTR 0.7.0

• Added a CRAN-safe popular R workflow example script covering stats::lm(), stats::glm(), stats::kmeans(), stats::prcomp(), optional rpart::rpart(), and matrix-to-grid conversion through datasets::volcano.

XGeoRTR 0.6.0

• Added runnable, CRAN-safe examples to all exported help topics so package checks no longer report checking examples ... NONE.
• Added documentation coverage tests to ensure exported .Rd topics retain \examples{} sections and to prevent regressions in future releases.
• No backend contract or public API changes in this release; the update is limited to documentation quality and release-check stability.

XGeoRTR 0.5.0

• Added INTERFACE_FREEZE.md and recursive contract tests to lock the XGeoRTR/ggWebGL ownership boundary.
• Added renderer-agnostic table helpers: xgeo_explanation_table(), xgeo_point_values(), and xgeo_regular_grid().
• Centralized selection-aware point/feature filtering for downstream packages.
• Clarified the public interface freeze around xgeo_state; use-case packages should consume backend state and generic tables rather than internal data structures.

XGeoRTR 0.4.0

• Hard architectural break: xgeo_scene has been replaced by backend-neutral xgeo_state.
• Added as_xgeo_state(), write_xgeo_state(), and read_xgeo_state().
• Added backend accessors: xgeo_geometry(), xgeo_attributes(), xgeo_indices(), xgeo_selection(), and xgeo_metadata().
• Removed renderer-facing API from XGeoRTR: render_webgl(), snapshot_webgl(), render_xgeo_layer(), and all geom_xgeo_*() constructors.
• Retargeted embedding/diagnostics/LOD/selection operators to xgeo_state.
• xgeo_data is now internal-only and no longer part of the public API.

XGeoRTR 0.2.0

• Redesigned xgeo_data as a normalized platform object with explicit points, explanations, point_meta, feature_meta, predictions, and uncertainty.
• Preserved unmapped point-level metadata during as_xgeo_data.data.frame() ingestion instead of dropping extra columns.
• Expanded xgeo_scene() to own embeddings, diagnostics, LOD state, views, selection state, and scene metadata.
• Added compute_xgeo_embedding(), compute_xgeo_diagnostics(), build_xgeo_lod(), set_active_embedding(), set_xgeo_selection(), and set_xgeo_lod().
• Added geom_xgeo_points() and geom_xgeo_density() alongside the existing geom_xgeo_surface().
• Added JSON scene IO through write_xgeo_scene() and read_xgeo_scene().
• Removed the misleading public animate_camera_orbit() helper because the renderer does not execute camera animation paths in this release.
