@@ -73,7 +73,7 @@ The mapping is per parameter, and additive:
 
 - a mapped parameter always filters the column it names; that column's type in the table decides how the value is formatted, exactly as for a name match
 - a parameter with no mapping keeps the default name match, so a single instance can mix mapped and unmapped parameters
-- the key is matched case-insensitively against the parameter's label, then against its internal name (e.g. `pr273`)
+- the key is matched case-insensitively against the parameter's label
 - an entry is split at its last `-`, so a label may itself contain hyphens (`Sales-2024-DEPT` maps the label `Sales-2024` to `DEPT`)
 - if the named column is not in the table being opened, the parameter is ignored rather than falling back to the name match - a typo cannot silently filter the wrong column
 - a column name that is not a plain SAS name is ignored
