How it works
Cliff heads score the same feature vector as LTOE — zero extra inference cost — and are calibrated isotonically. The output rides the LTOE payload as a sibling field, flagging when a tyre is approaching the steep part of its degradation curve rather than linear wear.
Inputs
- LTOE feature vector
- stint age vs compound life
- degradation trend
Output
Calibration
Isotonic calibrator fitted on held-out stints. See the calibration reference for the shared pipeline.
