Right, but access to the training pipeline and intermediate checkpoints can allow us to catch the development of these structures in model weights before they become fully undetectable! It's a bit like monitoring agents communicating over noisy channels: it's interpretable for a while, but as soon as they come up with asymmetric key exchange, anything that looks to you like "noise" might actually be the agents scheming. So it's important to catch this _before_ it occurs!
