+- name: definition_precision
+  value: 5.0
+  max_value: 5.0
+  rationale: The definition is highly precise, clearly distinguishing primogeniture
+    from other inheritance systems by specifying undivided inheritance to the eldest
+    son and explicitly contrasting its purpose (power/protection) with mere subsistence.
+    It avoids circularity and captures a distinct legal-economic concept.

+  max_value: 5.0
+  rationale: '"Regulation" is the correct domain placement, as primogeniture represents

+    rather than being a market mechanism or production process.'
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to S3 (internal regulation) as it represents an

+    choices about property rights and social organization.
+- name: explanatory_value

+  max_value: 5.0
+  rationale: This entity provides significant explanatory power by illuminating how
