Resolved GitHub repositories used by the verified playground build, combining direct and indirect dependencies. This list does not describe internal module dependencies or native system libraries.
No additional GitHub package dependencies were recorded for this verified build.
Build record verified 2026-10-28.
No other selected build records this repository as a dependency. This is not a measure of usage outside the catalog.
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: user residual Jacobian
Dense nonlinear least squares; Jacobian layout is parameters by residuals, transposed relative to MINPACK. For smooth nonlinear least squares, the user residual Jacobian supplies first-derivative information for the squared-residual objective; this is not a general scalar-objective gradient interface.
