If you are building AI agents, multi-agent systems, orchestration layers or autonomous workflows, this is for you.

If you are building AI agents, multi-agent systems, orchestration layers or autonomous workflows, this is for you. You already have intent, planning and tool use. HEIMEL starts where that becomes consequence. We have released it fully open source as a mechanically enforceable consequence boundary for agentic systems: fresh authority at consequence time exact state and effect binding one governed effect path one-shot permits verifiable execution evidence unknown fails closed Bring your agent architecture. Integrate HEIMEL underneath it. Attack the invariants. Try to bypass the governed path. Break the permit model. Test stale authority. Test replay. Test direct effect paths. If it holds, use it. If it breaks, show us and improve it with us in public. https://github.com/Heimel-open/Heimel Agent architectures can remain plural. The consequence boundary should not be.
