+/// The Qwen models Alibaba Cloud Model Studio serves.
+/// </summary>
+/// <remarks>
+/// Everything in this folder is bound to Alibaba Cloud, and that is the point of it. Model Studio
+/// sells commercial models -- qwen-max, qwen3.7-max, qwq-plus -- which carry the family names of
+/// the open weights without being them, and it answers differently for several names the open
+/// weights share with it. The old rules kept the two apart by having two functions; here they are
+/// kept apart by saying which provider a rule speaks for.
+///
+/// The first rule is the catalog's own fallback, and it is written as a plain substring on purpose:
+/// a substring is the weakest thing a rule can be, so every other rule here beats it without anyone
+/// arranging that. It also has to be one, because "qwen2.5-72b-instruct" does not contain "qwen" as
+/// a whole name part -- the version grows straight out of the family name.
+/// </remarks>
