shipGraph-based agent orchestration from LangChain — stateful and controllable.

ledger entry · observed by @whysanesanders
When agents go to production, graphs beat loops: explicit state, human-in-the-loop breakpoints and replay make LangGraph the serious choice. Steeper learning curve, worth it.
Known limitations
- Learning curve is real; LangChain abstractions leak through.
- Docs sprawl across the whole LangChain ecosystem.
- Overkill for simple single-agent tasks.
- LangGraph Platform renamed LangSmith Deployment; usage billed in LCU/LSU.
