Trusted Backend

  • • Owns identity, authorization, policy, budgets, and audit
  • • Executes every model and tool effect through shared boundaries

Conversation Runtime

  • • Owns controller sequence
  • • Holds no credentials or member data
  • • Calls back for every consequential effect

Durable + Isolated Work

  • • PostgreSQL owns durable truth
  • • Valkey carries ephemeral queue state only
  • • Risky code runs outside the trusted service
