Turn a worldly AI into a robot and it aces color-matching but flunks 'is this alive?' -- knowledge its original model had cold. A new test proves fine-tuning silently strips most of a model's common sense, and standard robot benchmarks would never catch it. We trace the same trap into coding agents, then dig into the fix two unconnected teams landed on the same week: stop cramming everything into one specialized model, and hang an evolving, readable library of skills off the side instead. Plus the day's headlines -- China's top open-weight model, the $10,000 MacBook AI tax, Fable 5's return, and coding agents that pass the test while the feature is dead.
