I thought of all the times a program wouldn't start because of port conflicts. The more I thought about it, the crazier it seemed. Modern operating systems already offer no-conflict ports: if you make yo

We can then use this to train a router for frontier, OS, and local models (use defaults or pick which ones to optimize against). wmo ingests agent traces, builds the simulation, embeds the traces, runs differe
