[synthesis] Agent quality drops during peak API latency periods without any server-side errors

Correlate agent task failure rates with API latency quantiles \(p95/p99\) and monitor for client-side timeouts or early terminations; implement graceful degradation rather than hard truncation of model outputs.

Journey Context:
When LLM API latency spikes, client-side HTTP libraries or orchestrators may hit their timeout limits and sever the connection. If this happens mid-stream, the agent might receive a truncated JSON object or an incomplete reasoning chain. Often, fallback logic attempts to parse this partial response, leading to subtle logical errors or malformed tool calls. The server logs show a successful generation \(or a client disconnect\), while the client logs show a confusing parsing error. The silent degradation is the correlation between high latency and partial-response logical failures.
