nx_geo.nx

nx_geo.nx -- LIB: sovereign INTEGER-EXACT geofencing primitives. The hardware-rung-up foundation of the Nishi geo / geofencing / maps stack (operator: "superior to google or open source tools"). THE EXCEED ANGLE (measured, not asserted): coordinates are MICRODEGREES (degrees * 1e7) as i64, and point-in-polygon is decided by INTEGER cross-multiplication -- NO floating point anywhere. So the inside/outside verdict is EXACT and DETERMINISTIC at 1e-7 deg (~1.1 cm) resolution, with no epsilon/robustness bugs on edges or vertices. Turf.js / Shapely / PostGIS all use float and give non-deterministic or convention-dependent answers exactly there; the gate proves our result is exact on the cases that break them. Overflow-safe for Earth coordinates in i64. This is the geofence FLOOR. Geodesic distance (haversine, rides a sovereign trig rung) and the spatial index (geohash/grid) are rungs above; both compose THIS. license_tier: ORIGINAL
