One authoritative service

  • • Public API and MCP share contracts and policy
  • • Consumers never bind to corpus tables or blob layouts

Fail closed at the boundary

  • • Every call carries tenant, principal, scopes and content policy
  • • Raw prompts, legal text and credentials stay out of logs
