.. _auto_curves_lower_bound:

*COMPUTE THE LOWER BOUND FOR A SET OF CURVES*
=============================================

Computes the element-wise lower bound (minimum envelope) across a set of input curves, returning a single bounding curve. Use this worker when you need to extract the worst-case minimum response from a family of curves, such as corridor checks or scatter-band analysis.

When to use

Classification: **process**.

     - Collection of two or more curves (vector type, multi-select) over which the element-wise minimum is computed; leave empty only if downstream logic supplies the curve group dynamically.
