A.19.ULSAM:1 - Problem frame (normative)

Within CHR, teams frequently need an explicit aggregation step (Γ‑fold) to produce an aggregated measure that is later consumed by comparison and/or selection. Without a dedicated mechanism boundary, aggregation tends to:

  • leak into scoring (“the score function also averages everything”),
  • leak into selection (“the selector silently computes a scalar”),
  • become an “implementation default” rather than a declared policy,
  • violate scale lawfulness (especially via ordinal arithmetic or unit-mixing),
  • become unauditable (“what exactly got folded, and under what evidence posture?”).
