<divclass="textblock"><p>Scratchpad implementation for the GraphEngine using CppAD automatic differentiation. </p>
<p>This header defines the GraphEngineScratchPad, a concrete implementation of AbstractScratchPad designed for use with the GraphEngine. It provides thread-local storage for CppAD automatic differentiation functions, Jacobian computation work structures, and cached derivatives used during ODE integration.</p>

<dlclass="section user"><dt>Thread Safety</dt><dd>This class is <b>not thread-safe</b>. Each thread must have its own instance of GraphEngineScratchPad because CppAD ADFun objects maintain internal state that is modified during evaluation. Use clone() to create independent copies for parallel workers, ensuring each thread has its own ADFun instance.</dd></dl>
