+ Warm public-HTTPS latency including RTT, measured from the same client with concurrency one. SPEV ran on an RTX PRO6000 with native vLLM pooling. Each row has 30 measured pairs over six fixtures after three warmup pairs. OpenAI used `gpt-6-luna`; audio includes a fresh `gpt-4o-mini-transcribe` request before Decisions. These measurements cover latency, not accuracy.
