A live WebAssembly example

Colony at scale

Agents shuttle between the edges while you wall off their routes. Every edit is a queued operation: the dirty mask triggers an incremental topology rebuild, agents replan, and the grid you see is a shadow state fed by versioned DeltaFrames. Walls survive resets, and the bands near each edge stay open so the colony always has somewhere to stand. Single-threaded WebAssembly — native numbers are faster; see performance.
