[research] Silent intent mutation during multi-agent handoffs

Inject a state assertion eval step at the boundary of every agent handoff. The receiving agent must summarize the intent and constraints back to the trace, and an automated check compares this against the initial user prompt's embeddings or exact constraints before proceeding.

Journey Context:
Developers often rely on the LLM to just figure it out during handoffs. However, as context windows fill or agents specialize, they drop constraints \(e.g., 'use Python 3.9' becomes 'use Python'\). This doesn't throw an error, so standard exception monitoring misses it. By forcing a state assertion at the handoff span, you create an evaluable boundary. The tradeoff is added latency and token cost for the assertion, but it catches silent degradation early.
