The point mikehostetler makes – 'agents must be architecturally correct WITHOUT LLMs before they can be correct WITH LLMs' – is underappreciated in most production deployments. We see this constantly: the failure mode isn't model quality, it's undefined operational boundaries and missing human-in-the-loop checkpoints for edge cases. Supervision trees as a first-class design primitive rather than an afterthought seems exactly right. What's your experience with teams that skip the architectural correctness step and go straight to LLM integration?
