A.19.USCM:5.1 - Tell

Think of USCM as admissibility‑gated scoring:

  • Input: “an admitted profile of measures for this exact bearer, criteria, scope and window, comparison basis, evidence policy, and result use, plus the CN-Spec and CG-Spec editions that declare those bounds”
  • Output: “a set of score measures that downstream steps may compare/select on”

The key didactic boundary is: USCM is allowed to transform measures only within the admissibility surface (SCP+CSLC), and it must not hide normalization, aggregation, or ordering.
