+    Human-readable prescribing detail
+    =================================
+
+    Purpose:
+    Return row-level prescribing detail with medicine and organisation codes
+    replaced by useful names.
+
+    Use this after an aggregate measure finds a cohort that needs checking.
+    Keep the output explicit. Avoid SELECT rx.* in shared audit extracts.
