A.19.CHR:5.1 - U.System vignette (Tell–Show–Show)
Tell. A system-level decision must select a declared set of options when measurable evidence comes from multiple slices (test rigs, simulations, field trials). Measurements are multi-scale and not always comparable without explicit normalization, and some evidence is missing or stale. The team needs lawful comparison and selection without forcing a single scalar “fitness”.
Show. Use the filled reference selection in §4.8.1 as the baseline: exact contracts, scales, methods, time rule and policies yield a retained set of two offers. When the inputs instead come from tests or field trials, replace the stipulated case evidence with the evidence required by the actual CN-Spec/CG-Spec; incomplete evidence follows the declared failure rule. A claimed dated Work and any launch witness require their independent enactment basis. Any actual semantic/kind/plane relation or flow/gate crossing retains its own required anchors.
Show. If the team instead embeds normalization inside scoring (“we always normalize to [0,1]”) or collapses a partial order into a single weighted sum, the suite protocol explicitness and “no silent scalarization/totalization” obligations make the violation legible at review time, and the planned baseline cannot honestly pin the missing UNM/ULSAM steps.
