Spatial selectors now support explicit spherical geometry lookups. Dateline and polar queries use conservative unit-sphere XYZ bounds and exact spherical predicates, while stored and emitted geometries remain longitude/latitude.
This adds finite great-circle interval boxes, RelateNG crossings/overlaps, point-only spherical
Near, manifold-preserving lookup operations, and per-column GeoParquet-styleedges/orientationmetadata alongside the existing GeoInterface CRS and geometry-column metadata. Planar remains the default. The implementation plan and current limits are documented indocs/src/spherical-plan.md.Validation: the full test suite passed on Julia 1.13; construction (161 checks) and spherical regressions (65 checks) also passed on Julia 1.10.12; a DataFrame metadata round-trip passed. General spherical nearest-geometry distance, datum-radius resolution, USP input, and spherical reprojection/zonal operations are subsequent work.
