 "what_this_measures": "Nothing new at run time — the page's speed and residency rows re-quote the chair trials' and August arrivals' published kits under their own counting rules. What this kit adds: the active-weights derivation (every tensor bucket and byte for both mixtures, computed from the model files' own shapes — the first time the vendor labels were checked against anything) and one pre-registered n=5 illustration bench (the robber question, both architectures, temperature 0).",
 "not_a_standard": "One card, one runtime, our own models. The derivation is checkable by anyone with the one command in the kit; the robber rows are an illustration under a registered rule, never a ranking.",
