[research] Agent silently degrades in production without throwing errors

Implement outcome-based assertions using LLM-as-a-judge on final outputs, rather than relying on process-based metrics \(like step completion or lack of exceptions\). Track semantic drift using golden datasets.

Journey Context:
Agents rarely crash; they just hallucinate or loop. Process metrics \(did it finish?\) miss semantic failures. LLM-as-a-judge catches this, but requires a strict rubric to avoid the judge agreeing with the agent. You must log the final state and run async evals against it to catch silent degradation before users do.
