[research] Multi-agent context loss or mutation during handoffs between agents

Inject trace-level evals at the handoff boundary to verify that the receiving agent's prompt contains the required state and that the output matches the expected schema before execution continues.

Journey Context:
In multi-agent systems, agents passing messages often drop critical context or hallucinate new state. Just evaling the final output misses where the divergence happened. By adding an assertion/eval step between agent transitions, you can pinpoint exactly which agent corrupted the workflow, turning a massive search space into a localized debugging task.
