  "business_question": "Does exact input-token admission protect realtime latency from a burst of large requests better than request-count admission?",
  "answer": "Exact-token admission activated flow-control queues in every run. Mean realtime burst p95 TTFT was 337 ms with exact-token admission and 354 ms with request-count admission. The 16 ms difference was not statistically significant.",
  "decision": "Keep request-count admission at 128 requests with 10% headroom as the default. Use exact-token admission when request sizes vary enough to need size-aware queue activation.",
  "claim_boundary": "The 95% confidence interval for the paired difference ranged from -24 ms to 57 ms and included zero. The data proves detector behavior, not a general latency advantage.",
