An embedded Elixir enforcement layer between autonomous agents and production systems. Tool calls, returned data, and outbound transfers pass through *deterministic policy before execution*. Secret scanning, source-to-sink controls, pinned tool manifests, exact-action confirmation, signed attestations, and audit records turn agent authority into an inspectable security boundary. The decision path stays inside the host application, removing a network dependency from the point of enforcement. SigilGuard supplies the control layer required when probabilistic models gain access to consequential tools.

*Agents act; the host decides, and keeps the evidence.*
