Reviewed procedures
These mappings have pinned source evidence. A checked package example may exercise only some of them; source review is not a numerical benchmark.
Derivatives / callbacks: analytic or approximated Jacobian, configured at initialization
Newton/quasi-Newton nonlinear system solver; callback and matrix configuration matter. The checked F2 driver solves [1-x,10*(y-x**2)]=0 from [-1.2,1] and [2,2], requiring the known root [1,1], small recomputed residuals and documented successful termination. Configuration: analytic dense Jacobian; backtracking; no Broyden updates. Other problem dimensions, singular systems and global convergence are not verified.
