Architecture Diagrams

Visual reference for Ironflow’s architecture at multiple zoom levels.

Diagram	Description
System Overview	30,000ft view: single binary, NATS, DB, SDKs, dashboard
Request Lifecycle	What happens when an event is emitted (push + pull paths)
Resource Hierarchy	Org → Project → Environment → Resources, IRN naming
Event Sourcing Flow	Entity streams, projections, upcasters, read models
Execution Engine	Step state machine with memoization, retry, and yield states
Multi-Node Cluster	Nodes, NATS cluster, PostgreSQL, coordination mechanisms
Auth & RBAC	Request → key lookup → role → policy evaluation → allow/deny
SDK Architecture	Browser/Node/Go SDKs, push vs pull, communication protocols
Flows	End-to-end data flow diagrams: emit, sync, ingest, pubsub, entity streams, cancel
