An Open Source jacket actually makes more sense to me than an open source LLM. I generally understand hardware to be open source when all design files are available (for example CAD models of a case and KiCad files for a PCB). If the patterns of a jacket were available in an editable standard-format file, you could argue that’s an open source jacket.
