CrossMind: Red-Teamed Capital Protection Agent

CrossMind introduces Proof of Preservation Alpha (PPA), a new metric that quantifies the economic value of not trading. Where on-chain verification confirms execution, PPA evaluates the value of non-execution. Across 11 real market crash scenarios, CrossMind issued 66 intelligent refusals with 100% Refusal Confirmation Rate: every refusal was retrospectively validated by subsequent price decline within the crash window, verified against historical Kraken OHLCV data. The numbers: $33,000 in notional risk was blocked across 4 crash environments (Japan Carry -24%, March Correction -26%, Terra/LUNA -54%, COVID -54%). Against $520 in realized losses, those refusals shielded $14,700 in capital from adverse exposure — a PPA Ratio of 28x. A/B test against identical market data and scenarios confirms the advantage: - CrossMind (5% pos, circuit breakers): 11/11 survived, -$407 PnL, 2.9% worst drawdown - All-In Bot (50% pos, no guardrails): 10/11 survived, -$2,435 PnL, 23.8% worst drawdown - Momentum Chaser (30% pos, no LLM): 7/11 survived, -$6,599 PnL, 19.6% worst drawdown Intelligent constraints outperform unconstrained leverage by 6-16x on identical data. Architecture: four specialized agents collaborate — deterministic Analyst and Strategist for hallucination-free signals, LLM-powered Risk Manager and Adversary for nuanced judgment and red-teaming. Every decision runs autonomously signal, risk evaluation, execute/refuse, Trust Ledger append — with zero human intervention per trade. Every refusal carries a structured Refusal Impact Score, permanently timestamped. On-chain: registered as ERC-8004 Agent #12 on Ethereum Sepolia (AgentRegistry 0x97b07dDc405B0c28B17559aFFE63BdB3632d0ca3). 246 TradeIntents, 195 validation checkpoints averaging 96/100, HackathonVault allocation claimed. Refusals are verifiable artifacts，not self-reported claims. CrossMind does not promise profits. It delivers a 28x PPA: $28 of capital protected for every $1 lost.
