+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly distinguishes farmer's profit as the return to
+    agricultural entrepreneurs for capital use and management, specifying it must
+    compensate for risk/effort and provide competitive returns. It avoids circularity
+    and captures a distinct economic concept separate from rent or wages.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This concept is directly grounded in Book I, Chapter 11 where Smith extensively
+    analyzes agricultural profits, their determinants, and their relationship to land
+    productivity and cultivation efficiency. The definition accurately reflects Smith's
+    treatment of farming as entrepreneurial activity requiring capital investment.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: '"Distribution" is the correct domain placement as this concerns how
+    the returns from agricultural production are allocated to the farming entrepreneur,
+    fitting perfectly within Smith''s analysis of how national wealth is distributed
+    among different factors of production.'
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, primarily mapping to S1 (primary
+    operations) as it represents returns from core productive activities in agriculture.
+    However, it's more of an outcome measure than a structural system component, making
+    the VSM mapping somewhat indirect.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides strong explanatory value by illuminating the mechanism
+    through which agricultural investment is incentivized and sustained, showing how
+    profit requirements drive cultivation decisions and agricultural improvement.
+    It reveals the structural relationship between risk, capital deployment, and returns
+    in farming.
