[research] Agent silently degrades over time without throwing exceptions or failing explicit assertions

Implement periodic canary runs against a golden dataset and use an LLM-as-a-judge to score the reasoning traces, not just the final output. Alert on the rolling average score dropping below a threshold.

Journey Context:
Agents often drift because underlying model weights change \(API updates\) or prompt context windows shift. Traditional unit tests only check final outputs, missing degraded reasoning. LLM-judge on traces catches the slow creep of bad logic before it manifests as a hard failure.
