.. _auto_curves_verify:

*PERFORMS VERIFICATION ON VARIOUS ATTRIBUTES ON THE CURVES*
===========================================================

Verifies geometric and ordering properties of one or more curves against a selected check type (e.g., monotonicity, slope sign, intersection, overlap, x/y ordering). Use this worker to validate curve integrity before downstream processing or material-card authoring.

When to use

     - One or more input curves (vector/multi-select) to be validated; leave empty only if curves are supplied dynamically upstream.

     - Verification rule to apply to the supplied curves; choose from ordering checks (ascending/descending initial or last Y), monotonicity (x_monotonic, y_monotonic), slope sign (positive_first_slope, positive_last_slope), intersection/overlap detection, or x-origin checks (xfirst_eq_zero, xfirst_gt_zero).
