Headless, deterministic Go simulation of a two-chain village economy (beer/food and housing), built milestone by milestone from a single living spec.
SPEC iteration 22026-10-12 Go stdlib onlyall tests green
The full scripted two-chain economy runs to a stable equilibrium: measured labor utilization 0.86 against the paper budget's 0.84; the village settles at population 14 with houses at ~0.97 condition. Disasters (fire, storm) are opt-in; sweep tooling is deterministic across worker counts. The per-stage regression suite caught and fixed a real item-conservation leak.
