Report #77123

[synthesis] Agent returns incomplete but valid-looking responses during high latency periods

Correlate output token length and stop reason with API latency. If latency spikes and stop\_reason is length or output is truncated, flag as degradation rather than just a token limit error.

Journey Context:
Under high load or network latency, token generation can be interrupted or hit provider-side timeouts. The agent might return a truncated JSON or a partial thought that the orchestrator times out waiting for and uses the partial buffer. It looks like a valid but short response. Monitoring just 200 OK misses that the response was cut short by latency, leading to downstream failures in logic that expected complete outputs.
