about

nx_geo_gate.nx -- GATE (runnable) for the integer-exact geofence floor (nx_geo). Proves: POLYGON: square center IN, EXACT edge resolution (1 microdeg in=IN/out=OUT), concave L notch OUT + both bars IN (true ray-casting), bbox computed + pre-filter agrees RADIUS : within-R fence exact boundary (d2==r2 -> IN, +1 -> OUT) AND cos longitude-compression proven: at 45 deg a point 12000 microdeg EAST is IN while 12000 microdeg NORTH is OUT (a lon microdegree covers less ground than a lat one) -- all integer, no sqrt. Evidence -> knowledge/status/geo_gate.log (GEOGATE authored=organ ... verdict=GREEN). license_tier: ORIGINAL
