[research] Context loss and hallucinated state during multi-agent handoffs

Inject a structured state validation step at handoff boundaries; evaluate the 'handoff payload' explicitly rather than just the final output.

Journey Context:
When Agent A hands off to Agent B, B often lacks critical context or hallucinates missing variables because A didn't explicitly pass them. Just evaluating the final task success misses the fact that B recovered by luck or expensive re-search. By adding an eval step that checks the exact JSON payload passed between agents against a schema, you catch context-drift regressions immediately at the trace level.
