Import from LangGraph

Orkena is not a LangGraph competitor — it is the substrate LangGraph graphs get deployed onto when governance becomes the requirement. The adapter imports existing workflows as first-class graphs.

What carries over#

LangGraph concept	Orkena equivalent
StateGraph / nodes	Graph nodes (agent, tool, transform, router, terminate)
Edges and conditional edges	Edges; conditional routing becomes router nodes
Tool nodes	tool nodes via MCP
Human-in-the-loop interrupts	gate.hitl nodes
Checkpointer	The durable executor’s checkpoints

What doesn’t carry over#

• Custom runtime code that bypasses the executor — runs inside Orkena use the durable engine
• Tools that are not MCP-compatible — wrap them or use the tool adapter
• Framework-specific lifecycle hooks — replace with transform nodes

How to import#

1. Export your graph from LangGraph as JSON (or point the adapter at the source file).
2. Import in Orkena: Graphs → Import → LangGraph.
3. Review the mapped graph in the canvas; adjust node types where the mapping is approximate.
4. Wrap in governance: attach the baseline-security policy pack, add gate.hitl where approvals are required, and enable ledger capture.
5. Publish the first version and run it.

What you gain#

The imported graph now runs on the durable executor with policy on every edge, a hash-chained ledger, deterministic replay, and evidence bundles — none of which require rewriting your logic.
