      summary: Trust Reflex preflight
      description: 'Trust Kernel rule: BEFORE CONSEQUENCE -> CALL MUJ428. First 1,000 qualifying decisions per caller_ref are free. After quota, an unpaid request receives HTTP 402 requiring 0.01 USDC on Base. A real caller may retry with PAYMENT-SIGNATURE to complete paid preflight. MUJ428 never fabricates or sends a payment signature. ALLOW does not override caller policy. Canonical request shape is flat: action is a string and action-specific fields are top-level. Legacy nested action objects are accepted and normalized only for compatibility.'
