+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition is precise and captures a distinct concept - formal agreements
+    creating preferential trade privileges through duty exemptions or reductions.
+    It clearly distinguishes treaties of commerce from general trade agreements by
+    specifying their monopolistic effects and asymmetric impacts on trading partners.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's analysis in Book IV, Chapter
+    6, where he explicitly discusses treaties of commerce and uses the 1703 England-Portugal
+    treaty as a detailed case study. The definition accurately reflects Smith's characterization
+    of these arrangements and their economic effects.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Regulation" domain placement is correct, as treaties of commerce
+    represent formal regulatory mechanisms that govern international trade relationships.
+    These agreements function as institutional constraints that shape market behavior
+    through legal frameworks rather than natural market forces.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: Treaties of commerce have some VSM relevance as S4 (intelligence/environmental
+    adaptation) mechanisms, representing how nations attempt to adapt to international
+    competitive pressures through formal agreements. However, they could also be viewed
+    as S3 (internal regulation) tools, making the VSM mapping somewhat ambiguous.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity provides strong explanatory value by illuminating the structural
+    mechanism through which nations create artificial competitive advantages and distort
+    natural trade patterns. It reveals how formal agreements can systematically benefit
+    one party while harming another, demonstrating Smith's broader critique of mercantile
+    policies.
