A colony sim with 4,000 simultaneous agents sharing a single dependency graph of jobs. It needs more memory than WebGL will give it, so this one is a download.
One dependency graph for the whole colony, re-planned incrementally. Agents claim leaves; nothing is assigned top-down.
Flow fields per region, stitched at portals. 4,000 agents, one field update per region per tick.
Deterministic binary snapshot plus a command log. Saves are 2 MB and load in under a second.
The heap sits near 1.4 GB in the late game. Browsers are not interested, and I stopped pretending otherwise.
Determinism bugs are the only bugs that make you doubt your own memory. All eleven are fixed.
