G.3:8 - Common Anti‑Patterns and How to Avoid Them

• Hidden cardinalization. Don’t treat ordinal encodings as interval/ratio; do publish coordinate policies that explicitly preserve order‑only invariants and forbid arithmetic upgrades.
• Unit laundering. Don’t add or average quantities with incompatible units; do force explicit unit discipline and legality checks via MM‑CHR governing definitions.
• Polarity drift. Don’t rely on “higher is better” implicitly; do publish polarity explicitly and make downstream use auditable.
• Threshold leakage into CHR. Don’t embed policy cut‑offs in CHR; do keep thresholds in CAL acceptance artefacts.
• Unpinned semantics. Don’t cite “the metric” or “the distance” without edition pins; do require edition‑pinned references when semantics affect interpretation.
• Unscoped reuse. Don’t reuse a characteristic or scale beyond its defining source and use on token continuity alone. Name the exact editions, bearer, scope and applicable window, reference plane, evidence, and intended downstream use; cite F.9 only when an actual relation between the named local senses is needed and obtains.
