A.19.ECS:9 - Rationale

Improvement cannot be better than its evaluation. A loop that changes an object version without a declared characteristic space can only produce activity, persuasion, or evaluator preference. An evaluation that lists scales without evaluated-object-kind discrimination, floor, evidence, missingness, trade-offs, and stop meanings cannot guide improvement safely.

Placing this method under A.19 keeps the ontology clean. A.19 governs the structure of CharacteristicSpace; A.19.ECS governs the construction method for evaluations of declared EntityOfConcern kinds and uses. A.19.ECS governs the selected characteristics, scales, coordinate construction, and evaluation-use boundaries of the evaluation characteristic space, not its publication or record form. An FPF pattern is only one possible publication form when the evaluation belongs in FPF; a local rubric, standard, table, or project rule is enough when the use is local. E.23 stays a universal loop method because it does not need to know how every domain chooses its scales. Domain and FPF-specific evaluations such as E.21, E.9.DA, E.2.DA, and F.18 keep coordinate choices inside those evaluations.
