    Congrats on the launch. We went down a similar path with OpenAmer (open source) and the lesson that stuck: for self-optimizing agents, the bottleneck is not making the agent smarter, it is verifying that each claimed outcome actually happened. We ended up routing every result through a heartbeat subsystem that re-checks it before it enters shared memory - without that, the agent happily builds on its own hallucinated successes. Curious whether Magnitude's self-optimization loop includes a verification stage or relies on the benchmark score alone.
