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

Inject a structured 'handoff manifest' \(JSON state object\) at the transition point, and write trace-level evals to assert the receiving agent acknowledges and uses the manifest fields before proceeding.

Journey Context:
Passing free-text context between agents leads to dropped instructions. The receiving agent might summarize or ignore key constraints from the previous agent. By forcing a structured manifest and evaluating the trace to ensure the next agent's first action utilizes the manifest, you guarantee state continuity. OpenAI Swarm explicitly uses structured handoff parameters and context\_variables for this reason, avoiding the ambiguity of conversational handoffs.
