+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition is quite precise, clearly identifying specific institutional
+    barriers (primogeniture, entails, servile labor, etc.) and their mechanism of
+    preventing farmers from capturing improvement value. It avoids circularity and
+    captures a distinct systemic phenomenon rather than a vague concept.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's central thesis from Book
+    III, Chapter 2, where he systematically analyzes how feudal institutions created
+    barriers to agricultural development. The specific mechanisms listed (primogeniture,
+    entails, insecure tenure, etc.) are explicitly discussed by Smith in this context.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Production" domain assignment is correct, as this entity deals with
+    factors affecting agricultural productivity and investment in productive improvements.
+    It fits naturally within Smith's analysis of what determines productive capacity
+    in different economic systems.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, primarily mapping to S4 (intelligence/environmental
+    adaptation) as it represents institutional failures that prevent the economic
+    system from adapting and improving agricultural practices. It could also relate
+    to S3 (internal regulation) regarding how institutional structures govern productive
+    activities.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides excellent explanatory value by illuminating the
+    structural mechanisms through which feudal institutions systematically discouraged
