[synthesis] Agent quality drops during peak hours without any increase in error rates

Instrument and group agent traces by execution path \(primary vs. fallback\). Alert on the ratio of fallback path invocations triggered by internal timeouts, not just external API errors.

Journey Context:
Production agents often have fallback mechanisms \(e.g., 'if primary LLM times out > 5s, route to cheaper/faster model'\). During traffic spikes, latency increases, causing the orchestrator to silently route a large percentage of requests to the fallback model. The fallback model is usually less capable. The system logs show 100% success \(no 500s\), but the quality of outputs plummets because the weaker model is doing the heavy lifting. Teams scratch their heads over CSAT drops that perfectly correlate with load, missing that their timeout thresholds are causing a silent model downgrade.
