  `GPSEdgeCost` (`0x44f838`), samples a generated traffic-lane spatial grid
  using the search-state coordinates, and applies highway/road/pavement
  multipliers to returned edge costs.
+- When the spatial patch is enabled, the plugin hot-reloads
+  `spatial_weights.bin` from the same directory as the DLL. The file is exactly
+  five little-endian float32 values in this order:

 - The old verbose local-search probe is still available behind
