    "summary": "Code Quality Gate Canonical owns the difference between a patch that works and a patch that should exist. It is the enforcement layer behind the project’s practical rule: less code only matters when the remaining code is cleaner, safer and easier to govern.",
    "function": "FUNCTION: Evaluate each change for duplicate logic, unnecessary append, stale helpers, broad mutation scope, layout drift, brittle fallback, missing validation and rollback weakness before promotion.",
    "system_position": "Diff / Patch / Replace Engine produces the mutation. Test & Validation Runner proves behavior. Code Quality Learning turns repeated quality outcomes into future discipline. This gate decides whether a technical fix also respects system architecture.",
