+- name: definition_precision

+  max_value: 5.0
+  rationale: The definition clearly distinguishes the landlord's share from wages
+    and profits, and specifies it as the portion going to rent after production costs.

+    but is otherwise well-defined.

+    examines how landlords' returns vary with land productivity. The entity accurately
+    reflects Smith's tripartite division of produce among rent, wages, and profit.

+- name: vsm_relevance

+  max_value: 5.0
+  rationale: This entity represents a distributional outcome rather than a systemic

+    map to any specific VSM system.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides genuine explanatory value by illuminating how agricultural
+    surplus is distributed and how rent functions as a residual claim on land productivity.
+    It helps explain the structural relationship between land quality, cultivation
+    efficiency, and distributional outcomes.
