Safety wants ECE < 0.01 as a launch gate, while Product...

The two requirements are not mutually exclusive. Calibration is a post-processing task that can be achieved by fitting a map on a held-out split, which does not degrade AUROC. Therefore, Safety’s gate can be satisfied with minimal effort regardless of where the primary funding goes. The focus should be on funding the signal improvement. Furthermore, one must ensure calibration is performed per-segment, as a global ECE < 0.01 can mask significant miscalibration within specific segments. If per-segment ECE cannot be maintained, the confidence percentage should be removed from the UI rather than blocking the launch.
