QODE protocols and their input models: ordinary-differential-equation routes such as Schrödingerization, LCHS, and contour decomposition, Fokker–Planck/SDE inputs, and Carleman linearization lifting nonlinear problems. The entries come from the `qode` and `qnlss` subpackages; for the spatial discretization inputs of PDEs see the QFVM application page.
