+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition is clear and precise, distinguishing the dealer's own
+    maintenance needs from other business costs by drawing a specific analogy to worker
+    wages. It captures a distinct economic concept rather than being vague or circular.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: The entity is directly grounded in Smith's text with an exact quotation
+    provided, showing that Smith explicitly discussed this concept using the specific
+    analogy between advancing wages to workers and advancing subsistence to oneself.
+- name: domain_placement
+  value: 4.0
+  max_value: 5.0
+  rationale: Placement in "Distribution" is appropriate since this concerns how economic
+    value flows to support the dealer's livelihood as part of the broader distribution
+    of economic returns. It could potentially fit in a "Production" domain but Distribution
+    captures the essence well.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This maps reasonably to S1 (primary operations) as it represents a fundamental
+    operational requirement for the dealer to function, though it's more of a constraint
+    or prerequisite rather than a core VSM process. It's not strongly VSM-oriented
+    but has some natural placement.
+- name: explanatory_value

+## definition_precision — 4.0 / 5.0

+The definition is clear and precise, distinguishing the dealer's own maintenance needs from other business costs by drawing a specific analogy to worker wages. It captures a distinct economic concept rather than being vague or circular.
