| Name | Description |
| AnchorSeeking | Anchor-based proximity (default). The right-hand value represents the expected or target value. Proximity is highest at this anchor and degrades as distance increases. The range defines the tolerance window around the anchor. |
| RangeCenterSeeking | Range-center proximity. Proximity is highest at the midpoint of the range and degrades symmetrically toward both boundaries. The range itself defines normality. |
| InsideOrOut | Binary containment behavior. Values inside the range are considered valid; values outside the range are invalid. No distance or proximity scoring is applied. |
| EdgeSeeking | Edge proximity behavior. Proximity increases as values approach the nearest boundary of the range. The center of the range scores lower than the edges. |
| TolerantContainment | Containment-tolerant behavior. Values inside the range score highest, while values outside the range degrade gradually instead of failing immediately. |
| OutsideSeeking | Outside-seeking behavior. Values outside the range score higher than values inside the range. Proximity increases with distance away from the range. |
