I1 includes both the ordinary differential and differential-algebraic integrators.
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.
Build record verified 2026-10-28.
These selected builds include this repository directly or indirectly. Each link to source identifies the revision that build uses.
These mappings have pinned source evidence. A checked package example may exercise only some of them; source review is not a numerical benchmark.
