+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly captures Smith's principle of proportional taxation
+    based on ability to pay, avoiding circularity and distinguishing it from other
+    tax concepts. It could be slightly more precise about what "ability to pay" means
+    in practice, but the core concept is well-defined.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity directly reflects Smith's first maxim of taxation from Book

+    expenses "as nearly as possible, in proportion to their respective abilities."
+    The concept is clearly and prominently articulated in the source text.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: '"General Theory" is the appropriate domain placement since this represents

+    framework of his economic theory.'
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to S5 (identity/policy) as it represents a core
+    policy principle that defines the identity and values of a viable economic system.
+    It also has some relevance to S3 (internal regulation) as it guides how the system
+    should regulate resource extraction from its components.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides genuine explanatory power by illuminating Smith's
+    underlying philosophy about fair resource distribution and social stability through
+    proportional contribution. It reveals the structural relationship between individual
+    capacity, state protection, and fiscal obligation rather than merely naming a
+    surface phenomenon.
