[research] Context loss or hallucination during multi-agent handoffs

Inject trace-level evals at the handoff boundary: programmatically compare the summary/context passed to the next agent against the original request using an LLM-as-a-judge, scoring for 'core intent preservation' before the next agent starts execution.

Journey Context:
In orchestrator-worker patterns, workers often receive condensed summaries that lose the nuance of the original prompt, leading to correct but irrelevant work. Evaluating only the final output makes it impossible to pinpoint where the context was lost. Evaluating the handoff payload isolates the orchestrator's failure from the worker's failure.
