Here's the thing about agent orchestration—at its core, it's really a constraint management problem. You've got multiple agents operating in parallel, competing for resources, and you need guardrails that actually work. Think about it: without proper constraint handling, your orchestration falls apart the moment market conditions shift or liquidity dries up. The best systems don't try to predict every scenario; they build in flexibility while keeping hard limits on what can go wrong. That's where the real engineering happens.
