DAGI / microdao Architecture Inventory — Executive Summary

Generated: 2026-02-16 Scope basis: docs/SESSION_STARTER.md + repository scan + operator clarifications (current thread decisions).

Executive Findings (Updated)

• Canonical deployment authority is per-node compose manifests, not a single universal file.
  • NODE1: docker-compose.node1.yml
  • NODE3: docker-compose.node3.yml
  • Staging: docker-compose.staging.yml (+ overrides)
• Drift-check policy should run per node against its local compose stack (services/images/ports/volumes/networks/env-nonsecret/healthcheck).
• ingest-service, parser-pipeline, control-plane are currently treated as not active on NODE1; catalog now uses lifecycle statuses (DEPLOYED, DEFINED, PLANNED/EXTERNAL).
• NATS canonical run subject policy is set to:
  • publish: agent.run.requested.{agent_id}
  • subscribe: agent.run.requested.* with dual-subscribe/publish migration window.
• Proxy policy is fixed at architectural level: single owner for 80/443 in production (nginx or Caddy), second proxy internal-only or disabled.

Priority Contradictions To Resolve

1. Memory API contract mismatch (/store in docs vs /memories//events//retrieve in code).
2. NATS run subject shape mismatch (legacy flat subject still in worker/producer paths).
3. Proxy ownership conflict (nginx vs Caddy) in runtime runbooks.
4. Architecture diagrams include services not currently deployed on NODE1.
