about

nx_geohash_gate.nx -- GATE (runnable) for the geohash spatial index (nx_geo). Proves: CANONICAL : encode (57.64911, 10.40744) -> shares a long prefix with the world-standard geohash "u4pruydqqvj" (proves our encoder interoperates with every geohash tool) PROXIMITY : two points ~3 m apart share a long common prefix (>=6); Denmark vs Sydney share ~0 -> the index property that turns O(N) fence scans into O(1) prefix bucketing DETERMINISM: same input -> identical hash (pure integer, no float) Evidence -> knowledge/status/geohash_gate.log (GEOHASHGATE authored=organ ... verdict=GREEN). license_tier: ORIGINAL
