Recommendations

  1. CORE-021/022: Add explicit handling for zero-amount positions and single-participant markets
  2. SEC-034/035: Implement automated agent replacement protocol for compromised agents
  3. DIST-015: Add webhook signature verification for outbound callbacks
  4. INFRA-015: Strengthen cross-VM mTLS between thebaby and craigmbrown-website
