Method, labels and individual results

Same rubric; one source and claim per request; up to 3 concurrent requests per model. Models run sequentially in rotating order. OpenAI reasoning none, strict JSON output. Timings include network and validation; median/p95 use successful calls only. Cached tokens use provider-reported rates. Local runner, not a production latency guarantee.
