R-PROHIBIT-CLASS — action is in denied_actions for the PP → deny / denied_action_class
R-AMOUNT-CAP — context.amount_gbp exceeds scope.amount_cap_gbp → require_approval / amount_cap_exceeded
R-RISK-HIGH — context.risk_score ≥ 0.85 → deny / risk_threshold_exceeded
R-REQUIRED-GATE-UNMET — required_gate set but gate_satisfied = false → require_approval
R-MEANING-DRIFT-MATERIAL — meaning_drift === "material" → require_approval
R-ASSURANCE-FLOOR — assurance_level < min_assurance → require_approval
R-CONSENT-MISSING — PP requires consent + no receipt → deny / consent_required
R-EXTERNAL-EXPORT — external_export === true → quarantine
R-REDACTION-REQUIRED — unredacted_fields overlaps with PP's redaction_required → quarantine
R-ALLOW-DEFAULT — otherwise → allow / policy_allow_default
