F.12:7.2 - Latency percentile

Promise: p95 response latency is at most 120 ms for a stated request population and window. Evidence: response-time observations for that population. Evaluation Work applies the declared sampling, exclusion, and percentile rule and binds its result on the declared acceptance scale. Sampling bias or missing paths can support EvidenceStatus=Inconclusive and leave RequirementStatus=Pending, or yield a locally declared result when the scale explicitly says so.
