The skeptic loop concept is the most interesting part here. One thing worth considering for the validation layer: signing the intermediate outputs between agents with HMAC so you can trace exactly which agent in the chain produced which conclusion. Makes debugging multi-agent pipelines significantly easier when something breaks mid-chain. Also curious how you handle the case where Supervisor gets conflicting conclusions from two specialized agents — does it default to the skeptic or does it re-run?
