+- name: definition_precision
+  value: 5.0
+  max_value: 5.0
+  rationale: The definition is highly precise and non-circular, clearly explaining
+    the specific banking practice of advancing money on bills of exchange before maturity
+    while deducting interest. It captures a distinct financial mechanism rather than
+    a vague concept.
+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is well-grounded in Smith's actual text, as he explicitly
+    discusses how banks profit from discounting bills of exchange in Book II, Chapter
+    2. The concept directly reflects Smith's analysis of banking operations and trade
+    facilitation.
+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Exchange" domain assignment is perfectly appropriate, as this practice

+    It sits naturally within the broader category of financial exchange mechanisms.
+- name: vsm_relevance
+  value: 4.0
+  max_value: 5.0
+  rationale: This entity maps well to S1 (primary operations) as a core banking service
+    that generates revenue, and also connects to S2 (coordination) by facilitating
+    trade flows and reducing temporal mismatches between merchants' cash needs and
+    receipts. It has clear operational significance within the economic system.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides excellent explanatory power by illuminating a key

+    and trade facilitation rather than merely naming a surface phenomenon.
