[research] Agent handoffs lose context or hallucinate state when passing control to another agent

Implement trace-level evals at handoff boundaries by enforcing strict JSON schemas for inter-agent payloads and validating them at runtime, rather than relying on unstructured natural language context passing.

Journey Context:
When Agent A hands off to Agent B using a natural language summary, B often misses critical variables or invents details. Trace-level evals inspect the exact payload at the handoff span. By forcing structured outputs at the handoff, you can programmatically eval if the required state was transferred. The tradeoff is loss of flexibility in natural language, but it drastically reduces handoff hallucination.
