+  rationale: This entity maps well to S4 (intelligence/environmental adaptation) as
+    it represents how England attempted to adapt to international competitive pressures
+    through strategic policy, and partially to S5 (identity/policy) as it reflects
+    national economic identity. The systematic nature of the policy makes it clearly

+- name: explanatory_value

+  max_value: 5.0
+  rationale: The entity provides genuine explanatory power by illuminating the structural
+    mechanism through which mercantilist principles were implemented in practice,
