The shim builds DetourCrowd from the same pinned Recast & Detour tag. nav_crowd_start puts a crowd on a kind's mesh, with the mesh's tastes as its filters. Walkers are added (snapped to the mesh), sent and sped through verbs, stepped together, and read back into nav_agent_*. nav_crowd_us times the stepping with the OS clock. Dropping a mesh drops its crowd first. On the test meadow, twenty walkers crossing head-on never come closer than their two radii (0.7003 m), all arrive, and a step costs about 12 us. nav 15/15 on the Mac and the PC; the DLL still imports KERNEL32 alone.

# builds lib/<target>/ for ludic.nav: Recast & Detour at a pinned tag, and the shim over them.

# Recast builds the mesh, Detour answers it, DetourCrowd steers many walkers at once (phase 18);

# DetourTileCache would come with 17.8. Polygon refs are 64-bit (DT_POLYREF64): an 8 km map in 64 m tiles is 16384 tiles, which

# 32-bit refs would leave 256 polygons each. Objects go to build/native; a few seconds on eight cores.
