[architecture] My agent loses track of long-running workflows when I restart the process

Persist full execution state — messages, tool outputs, and graph state — to a checkpoint store after every step. Resume from the latest checkpoint or a prior step instead of replaying from scratch.

Journey Context:
Statelessness makes long-horizon agents fragile: crashes or restarts lose progress and force expensive recomputation. LangGraph's persistence primitive checkpoints graph state so workflows can pause, resume, and even fork from earlier steps. This is distinct from memory retrieval: checkpoints capture transient execution context, not learned facts. Tradeoff: checkpoints can grow large and may contain sensitive data, so retention and encryption policies matter. Use checkpoints for execution continuity and memory stores for learned knowledge.
