Deterministic Multi-Agent Economic Simulation Engine

Closed-economy agent-based simulation in which heterogeneous agents extract resources from logistic niche pools, pay metabolic costs, reproduce via a four-trait fitness function, and face stochastic catastrophes. Every state transition is deterministically seeded via SHA-256 hash chains and Knuth MMIX LCG — bit-identical results on the same architecture. 44 experiment configurations across three research phases produced 6,820 independent world simulations totaling over 3,410,000 computed epochs. Dual-chain cryptographic integrity: SHA-256 state chain + BLAKE3 genome chain advance per epoch with divergence detection and full replay to any depth. Under the default collapse definition (P_floor = 3) no collapses were observed; under stricter definitions (P_floor ≥ 10) collapse rates exceed 97% — a sharp phase transition.
