Domain core: seeded RNG, asset registry, wallets, AMM pairs, mining
Pure logic layer with no game references: xoshiro128** RNG with savable state, asset registry (PSC, CRC, CRT, CRA, SPARK, Ponero), wallets whose taint and cost basis move with transfers, constant-product pools with nightly reversion, and mining (Probidia/PMD GPUs, RatDigg ASICs, network hash response, halving, wear and sudden death). 35 checks pass.
