A.19.UNM:4.2 - CN-frame wiring: normalization and comparability routing (normative-by-reference)
Tell. CN-frame does not “do normalization”; it routes normalization.
comparability.mode ∈ {coordinatewise, normalization-based}governs whether comparisons are done directly or “normalize-then-compare”.normalization.UNM_id?selects the UNM mechanism instance used by this CN-frame.normalization.methods / instances / method_descriptions / invariants / fixprovide the declared surface that UNM consumes. (If present)normalization.admissible_reparameterizationsconstrain which re‑parameterizations count as “admissible” under the declared invariants. (See CN-frame definition inA.19.CN;A.19.CNremains the governing pattern of the CN-frame surface. This section only states the UNM consumption/interpretation constraints and does not introduce a shadow spec.)
