about

nx_geo_match_gate.nx -- GATE for GEO-023 map-matching. Seeded road graph: edge0 = horizontal road (lat 0, lon 0..10e6); edge1 = vertical road (lon 5e6, lat 0..10e6). Snap 3 noisy GPS fixes: P0 (1e6, 3e6) -> edge 0, snapped (0, 3e6) [projects onto the horizontal road] P1 (4e6, 6e6) -> edge 1, snapped (4e6, 5e6) [projects onto the vertical road] P2 (0, -5e6) -> edge 0, snapped (0, 0) [before edge0's A endpoint -> clamp to A] Snapped points lie exactly ON the chosen edge (deterministic integer snapping). Evidence -> knowledge/status/geo_match.log (GEOMATCHGATE authored=organ ... verdict=GREEN). license_tier: ORIGINAL
