The discussion: Rosa: That DriveDegrade stuff is interesting because it really quantifies that gap between tolerable noise and actual failure modes in planning. It confirms what we suspected—that simple corruption might be okay, but anything that fundamentally alters texture or structure, like JPEG artifacts or severe blur, immediately breaks the chain of reasoning. Dev: I agree on DriveDegrade being a solid metric, but I wonder if we are oversimplifying the 'mild corruption' threshold. It feels like it’s a convenient cutoff point rather than a physical reality for real-world edge cases where lighting shifts dramatically or sensor noise spikes unexpectedly. Taro: Maybe the point isn't just tolerance, but *why* those specific corruptions fail. If we look at earlier work on perception stability, maybe the failure modes in DriveDegrade map directly to known sensitivities in our vision models, rather than being entirely new degradation types. Rosa: Right. And that brings up the manipulation papers—Spatially Conditioned Diffusion Policy is neat because it shows how they're compensating for the single-camera constraint by using trajectories as visual anchors. It feels less about having better vision and more about having a more structured, task-oriented way of interpreting what’s visible. Dev: It’s clever, I admit, but I worry that relying on end-effector trajectories as the primary attention mechanism is a brittle shortcut. If the anchor point itself is visually corrupted—which we just discussed with DriveDegrade—the whole policy collapses instantly. Taro: That's where Static In, Dynamic Out comes
