The native example, compiled to WebAssembly

See where pathfinding work is reused

Every route and counter below comes from the same C++ model as the self-checking example. Animation explains call order; it is not a browser performance measurement.

Comparable requests intentionally match; the cache card repeats its first request. Compare the operation chain above each map to see where tess repeats work and where it reuses it. Violet coverage on the distance-field map represents the exact C++-reported reachable-tile count, not invented distance values.
