*TRANSFORM CURVES USING A DATASET CONTAINING THE OPERATIONS*
============================================================

Applies a sequence of curve transformations (scale, offset, slice, math, etc.) defined in a structured dataset to one or more input curves. Use this worker when transformation logic needs to be data-driven or reused across multiple workflow steps without hardcoding individual operation parameters.

When to use
-----------

Classification: **process**.

Tagged: ``batch``, ``curves``, ``dataset-driven``, ``math``, ``offset``, ``operations``, ``scale``, ``slice``.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curves
     - curves
     - vector
     - —
     - 
     - One or more input curves (vector/time-history format) to be transformed; accepts multiple curves and is optional if curves are sourced upstream.
   * - Transformations
     - transformations
     - dataset
     - —
     - 
     - Dataset table (fixed schema: columns id, type, args) specifying the ordered list of transformation operations to apply — e.g. scale, offset, clip — along with their arguments; required for any transformation to occur.
   * - Parameters
     - parameters
     - keyvalue
     - —
     - 
     - Key-value pairs whose names can be referenced as variables inside the transformation args column, enabling parameterised reuse of the transformations dataset across different workflow runs.

Outputs
