[research] Agent handoffs lose context or hallucinate state between steps

Attach structured state payloads \(JSON\) to handoff events and validate them as independent trace spans. Do not rely on natural language summaries between agents.

Journey Context:
When Agent A hands off to Agent B via a text summary, B often misses constraints or invents details. By forcing the handoff to include a schema-validated JSON object \(e.g., \{"customer\_id": "123", "status": "verified"\}\), you can write deterministic trace-level evals on the handoff span to catch context loss immediately.
