A.19.CPM:9 - Consequences

• Improved usability (didactic): CPM gives a single, engineer‑readable place to learn “what admissible comparison means” and what it does not mean.
• Higher replayability: comparison results remain traceable through dated comparison U.Work, the actual Compare application and its ComparisonResultSlot binding, the A.10 evidence-provenance path, any consumed obtaining F.9 Bridge with its separate bounded-use claim, and any applicable ReferencePlane relation and policy.
• Reduced semantic drift: teams cannot silently shift from Pareto to lexicographic to “weighted sum” without changing explicit comparator specs and pins.
• Explicit tradeoffs: set‑valued outcomes force downstream reasoning to acknowledge incomparability and uncertainty rather than hiding them.
• Cost: downstream consumers (notably selection) must handle sets, abstentions, and partial orders explicitly. This is intentional: it moves complexity from hidden heuristics into explicit policy‑bound mechanisms.
