[research] Context lost or hallucinated during multi-agent handoffs

Inject trace-level evals at the handoff boundary by comparing the outgoing context of Agent A with the incoming context received by Agent B. Use an automated LLM-as-a-judge to score information retention and hallucination at the seam.

Journey Context:
Multi-agent systems fail not at the individual agent level, but at the seams. Agents often summarize or drop critical variables when passing context. Standard end-to-end evals won't tell you \*where\* the context was lost, only that the final answer is wrong. By evaluating the delta at the handoff trace, you isolate the routing/summarization logic from the execution logic, making debugging 10x faster.
