+- name: definition_precision

+  max_value: 5.0
+  rationale: The definition conflates the cybernetic concept of "requisite variety"
+    (from Ashby's Law) with basic banking prudence, creating conceptual confusion.
+    Smith discusses banking reserves and lending practices but does not frame these
+    in terms of matching "variety of demands" in the cybernetic sense.

+    a organizing principle. This appears to be a modern cybernetic framework imposed
+    on Smith's more straightforward discussion of banking stability.
+- name: domain_placement

+    context is also correctly identified from the source material.
+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: The entity could map to S3 (internal regulation) given its focus on maintaining

+    framing makes the VSM connection feel artificial rather than natural.
+- name: explanatory_value
+  value: 2.0
+  max_value: 5.0
+  rationale: The entity adds little genuine explanatory power beyond restating that
