+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly distinguishes between fixed capital (instruments
+    and breeding cattle) and circulating capital (wages and maintenance) in agriculture,
+    providing concrete examples for each category. While precise, it could benefit
+    from slightly more detail about the functional differences between these capital

+- name: source_grounding

+  rationale: This entity is directly grounded in Smith's detailed discussion of agricultural

+    and its division into fixed and circulating components. The examples of breeding

+- name: domain_placement

+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to S1 (primary operations) as it describes the
+    capital structure that enables the fundamental productive operations of agriculture.
+    It also has some relevance to S3 (internal regulation) in terms of how capital
+    allocation decisions are made within the farming operation.
+- name: explanatory_value

+  max_value: 5.0
+  rationale: The entity provides genuine insight into how capital functions in agricultural
+    production, illustrating the important distinction between fixed and circulating
+    capital through a concrete sectoral example. It helps explain the structural mechanics
+    of how agricultural profit is generated through both capital appreciation and
