Stateful Graph Orchestration — Durable Execution and Checkpoints
Agent is a state machine; nodes are functions; edges are transitions; state is checkpointed after each node. Resume from any failure at the last successful checkpoint. LangGraph is the 2026 reference for this model of low-level stateful orchestration.

It is part of the curriculum and will get the same treatment as Phase 1 — a visual cover, hands-on labs, derivations with numeric checks and a quiz. Until then, the original lesson is the best place to read it:
Part of Phase 14 — Agent Engineering. Use the previous / next cards below to keep browsing the phase.
