LangGraph for durable agent orchestration — checkpointing, retries, branching, and human-in-the-loop.
Agent runs are long-lived and must survive restarts.
You need checkpointing, retries, and resumable state.
The flow branches and needs human-in-the-loop approval.
Off-the-shelf single-prompt loops aren't durable enough.
Build logs, agentic engineering decisions, agent failures, evals, and what survives real users. Sent weekly, never more.
