Automation is not cognition
Keep deterministic triggers and business actions separate from stateful reasoning. The split reduces blast radius and makes failures diagnosable.
Workflow requirements
Auto-detect signals, then verify the operating constraints.
Recommended control plane
Use Hybrid
Use n8n at the integration boundary and LangGraph for stateful reasoning. This separates deterministic business automation from agent cognition while preserving one auditable operating model.

Implementation blueprint
Minimum viable production architecture—not decorative complexity.
Integration boundaryn8n webhooks, schedules, SaaS connectors, and deterministic actions
Reasoning runtimeLangGraph state machine with typed shared state and explicit transitions
PersistencePostgreSQL checkpoint store plus encrypted object evidence
GovernanceApproval gate, least-privilege tools, trace IDs, replay-safe writes
Failure policyBounded retries, dead-letter queue, idempotency keys, operator escalation
Deployment shapeContainerized agent service behind authenticated n8n workflows
