This reference is generated from the exercise specifications the analysis pipeline runs on, and from the metric registry that grades them. It covers the eight production-ready assessments.
For each metric it shows the key QOOM reports, its unit, what it measures, and its grade column: whether the registry holds a reference distribution for it, and whether the evidence gate can currently show a zone against that distribution. A metric with a reference distribution whose zone is withheld is still measured and reported, and its distribution stays auditable in the registry; it simply carries no green / yellow / red zone until the gate admits the evidence behind it. A metric with no reference distribution is marked —.
Reference data version: 2026-08-09.1. Evidence levels are explained in How thresholds were chosen.
