+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly distinguishes luxury taxes from other types of
+    taxes by emphasizing their optional nature and lack of broader economic spillover
+    effects. It precisely captures the key characteristics that make luxury taxes
+    distinct in Smith's taxonomy of taxation.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This concept is directly grounded in Book V, Chapter 2 where Smith explicitly
+    discusses taxes on luxuries as a distinct category and analyzes their economic
+    effects. Smith clearly contrasts luxury taxes with taxes on necessaries throughout
+    his discussion of taxation principles.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: '"General Theory" is the appropriate domain placement as this represents
+    a fundamental principle in Smith''s theoretical framework for taxation policy.
+    The concept operates at the level of general economic theory rather than specific
+    applications or mechanisms.'
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, most naturally mapping to S3
+    (internal regulation) as a policy tool for resource allocation and economic control.
+    However, it could also relate to S5 (policy/identity) as it reflects societal
+    choices about what to tax and how to distribute burden.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides significant explanatory value by illuminating Smith's
+    mechanism for equitable taxation that avoids distorting labor markets or essential
+    goods prices. It reveals an important structural principle about how different
+    types of taxes operate within the economic system.
