Summary

Bylaw builds evidence enforcement for AI agents, ensuring agents act only on verified, correct sources before taking action. It targets teams deploying autonomous agents where acting on wrong or missing evidence carries real cost. The product replaces manual review and ad-hoc prompt constraints with a structured guarantee layer that sits between an agent and its decisions.
