+- name: definition_precision

+  max_value: 5.0
+  rationale: The definition clearly distinguishes poll tax compensation as a specific
+    economic arrangement with fixed payments in exchange for exemptions, creating
+    a distinct concept from general taxation or feudal obligations. The definition

+- name: vsm_relevance

+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance, potentially mapping to S3 (internal

+    institutional arrangement rather than an active system component.
+- name: explanatory_value
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity provides excellent explanatory value by illuminating a specific
