+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly captures the core mercantilist belief that trade
+    surplus equals prosperity and that trade is zero-sum. It's precise and non-circular,
+    though it could be slightly more specific about the mechanisms mercantilists believed
+    drove this relationship.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This is directly grounded in Smith's text, as Book IV, Chapter 3 explicitly
+    critiques the mercantilist balance of trade theory. Smith repeatedly refers to
+    this doctrine and quotes the "national prejudice and animosity" phrase, making
+    this a central concept he addresses.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: '"General Theory" is the correct domain placement since this represents

+    Smith systematically dismantles.'
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This maps well to S4 (intelligence/environmental adaptation) as it represents
+    how nations conceptualize and respond to their external trade environment. It
+    could also relate to S5 (identity/policy) since it shapes national economic identity
+    and policy frameworks.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity has high explanatory value as it illuminates the fundamental
+    theoretical error Smith identifies in mercantilist thinking. Understanding this
+    doctrine is essential for grasping Smith's critique of trade restrictions and
+    his argument for mutual benefits from free trade.
