A.19.UNM:2 - Problem
Without an explicit UNM governing pattern:
-
Normalization drifts into hidden places. It gets embedded inside scoring, comparison, or selection, making admissibility and governance non-local.
-
Comparability becomes rhetorical. People say “we normalize” but cannot answer: Which method? Which invariants? Which bearer, comparison basis, scope and window? Which evidence? Does the receiving comparison rely on an actual Bridge, kind relation, or plane relation?
-
Basis and relation changes become invisible. Teams reuse normalizations for another bearer, comparison basis, source-local meaning, or reference plane without naming what changed or the relation on which the new use depends.
-
Engineers cannot reconstruct the mechanism. When UNM semantics are scattered, the pattern structure (problem/forces/solution) is lost, hurting didactic use by engineering managers.
