*ENFORCE DECAY - MONOTONICALLY DECREASING VALUES FOR Y*
=======================================================

Enforces monotonically decreasing Y-values on one or more curves by progressively clamping each Y value to be no greater than the preceding one. Use this worker to sanitize curves (e.g., decay, failure, or degradation data) that should strictly decrease but contain noise or non-monotone artifacts.

When to use

     - One or more input curves (X/Y vector pairs) whose Y-values should be made monotonically decreasing; accepts multiple curves and is optional — if omitted the worker passes through with no output.
