What this is
An adapter rather than a full checkpoint. You need Qwen/Qwen3.5-4B-Base alongside it, and the licence of that base applies to you as well as this repository's own.
A public number is a shortlist, not a decision
The only benchmark that settles which model you ship is one built from your own historical decisions. We freeze that test set, run the candidates against it, and hand back the threshold your error budget supports.
