[research] How to evaluate multi-agent handoffs without only testing the final output

Inject intermediate assertions at the handoff boundary using trace-level evals. Validate the context passed \(the handoff payload\) matches the receiving agent's schema and intent, independent of the final task result.

Journey Context:
End-to-end evals on multi-agent systems yield false confidence; a lucky final agent can mask a corrupted handoff state. By evaluating the exact JSON/context payload at the span boundary where Agent A yields to Agent B, you isolate routing and context-passing failures from reasoning failures.
