Domain: market, stablecoins, compliant cash-out with AML

Market: PSCoin reference price with sentiment, anchor shifts from game
events (blackout, crackdown), daily volatility, NPC whales, a day-average
mark price, and side pairs pulled toward the reference by arbitrage.
Stablecoins: CRC depeg and haircut, CRT depeg and freeze chance by black
market reputation, CRA staking subsidy, warnings and the three-day spiral.
Exchange: CRC cash-out at market price, AML hit chance from size, 7-day
total, taint ratio and mixer/flag; light hits confiscate the tainted part,
heavy hits also report it as fencing; tax only on gains.
