[research] Multi-agent handoffs cause cascading failures where the root cause is obscured

Propagate trace IDs across agent handoffs and implement 'eval-at-boundary' checks, validating the payload schema and semantic intent before the receiving agent starts processing.

Journey Context:
When Agent A passes bad context to Agent B, B's failure logs make it look like B's fault. Tracing alone isn't enough; you need evals at the handoff boundary. If A outputs unstructured garbage, B will hallucinate. Validating A's output as an eval step before B executes prevents cascading errors and correctly attributes the failure to A.
