Yes, but consumers buy, for example, graphics cards with binary blobs and are certainly not sent a specification of the software in them, or of the interfaces, etc. and that is what I believe is the absolute minimum foundation. So I mean an internal specification of all hardware interfaces and a complete description of software-- no source code, but a complete flow diagram or multi-process equivalent.
