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

Inject a structured handoff manifest \(JSON containing current state, completed steps, and remaining goals\) into the receiving agent's system prompt, and eval the receiving agent's first response to ensure it acknowledges this manifest correctly.

Journey Context:
When agents pass control via simple text completion, the receiving agent often hallucinates the previous state or loses critical constraints from the original prompt. Naive string-concatenation of chat histories leads to context window bloat and distraction. By forcing a structured handoff manifest and evaluating the transition step specifically \(trace-level eval\), you ensure state continuity without passing the entire raw history.
