A.19.USCM:9 - Consequences

Benefits

• Makes scoring a first‑class, admissibility‑gated CHR step, reducing illicit arithmetic and silent assumptions.
• Improves auditability and reproducibility via explicit edition pins and explicit evidence policy selection (override vs default).
• Preserves evolvability: scoring method families can change via SoTA wiring without changing the USCM intension.
• Supports correctness under uncertainty via tri‑state guards and explicit unknown handling.

Costs / trade‑offs

• Requires explicit CG‑Spec admissibility surfaces (SCP) and explicit evidence policies to achieve pass; this can feel slower than “just compute a score.”
• Vector scores can be less immediately comfortable than a single number; downstream comparison/selection must be explicit about how vector scores are used.
