+/// <remarks>
+/// This is the case the refinement exists for. Four Mistral families gained image input and
+/// reasoning at some release and carried the same name before and after, so no pattern can tell
+/// the two apart: mistral-large-2411 and mistral-large-2512 differ in what they can do and in
+/// nothing a rule could match on.
+///
+/// So the rule states what the family has always been able to do, and each family says from which
+/// release on it gained the rest. Everything shared sits here; a family below is three numbers and
+/// one rule.
