+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly captures a specific analogy Smith uses to illustrate
+    banking equilibrium through water flow dynamics. It's precise in describing both
+    the metaphor itself and its intended meaning about balanced lending/repayment
+    cycles.
+- name: source_grounding

+    operations. The entity accurately represents Smith's own illustrative device.
+- name: domain_placement

+  max_value: 5.0
+  rationale: '"General Theory" is the appropriate domain placement since this metaphor

+    sector but explains systemic dynamics.'
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: The metaphor has moderate VSM relevance as it describes operational balance
+    (S1) and regulatory equilibrium (S3), but it's primarily an illustrative device
+    rather than a structural component. It explains how systems should function rather
+    than being a system itself.
+- name: explanatory_value
+  value: 4.0
+  max_value: 5.0
+  rationale: The entity provides genuine explanatory value by illuminating the mechanism
+    of banking equilibrium through a vivid, accessible analogy. It helps clarify the
+    structural relationship between bank reserves, lending, and repayments in maintaining
+    financial stability.
