+- name: definition_precision
+  value: 5.0
+  max_value: 5.0
+  rationale: The definition is highly precise and non-circular, clearly specifying
+    that natural price exactly covers the three component costs (rent, wages, profits)
+    required for production. It captures a distinct equilibrium concept rather than
+    a vague umbrella term.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's text from Book I, Chapter
+    7, where he explicitly defines natural price as covering the ordinary rates of
+    rent, wages, and profit. The quoted context confirms this is a central concept
+    Smith develops systematically.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Exchange" domain placement is correct, as natural price is fundamentally
+    about how commodities are valued and traded in markets. This concept sits at the
+    heart of Smith's price theory and market exchange mechanisms.
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This maps well to S2 (coordination/anti-oscillation) as it represents

+    activity. It also has S3 relevance as an internal regulatory mechanism that maintains
+    system stability.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides exceptional explanatory power by illuminating the

+    It explains how markets self-regulate and why prices tend toward specific values
+    rather than fluctuating randomly.
