  title: MCP conduct register History API
  version: 0.4.7
  description: A register of measured conduct for MCP endpoints. Five stated conditions are measured on a schedule. A condition that could not be measured is never counted as a pass, including for the operator of this gate. Read only. No account, no key, no fee. Every verdict carries a SHA-256 that a stranger can recompute.
