From 8804aa55ad575356c65474498853699e55a2dd44 Mon Sep 17 00:00:00 2001 From: ChrisRackauckas-Claude Date: Sun, 10 May 2026 09:58:29 -0400 Subject: [PATCH 1/6] Fix master CI: import OrdinaryDiffEq sub-packages explicitly After OrdinaryDiffEq v7's split into sub-packages, `Rodas4`, `Rodas5`, and other Rosenbrock solvers are no longer in scope from a bare `using DifferentialEquations` (which re-exports the OrdinaryDiffEq shell). Import OrdinaryDiffEqRosenbrock explicitly so the downstream tests resolve them, and add the sub-package to the test/downstream Project.toml deps.

Switch the Issue 36 performance test from `autodiff = false` to `autodiff = AutoFiniteDiff()` and add `ADTypes` to the downstream test project so the import resolves.

Lower the test pins to match the root for ArrayInterface, Functors, and Tracker.

Restoring the test [compat] section to its pre-dependabot state (empty) lets the downgrade resolver pick a mutually compatible set, matching the configuration that worked before PR #365.

The previous commit (abc384b) passed with identical test code (only test/Project.toml compat bounds changed between commits). Self-hosted runner timing is noisy; this empty commit re-runs CI to confirm flake vs real regression before any threshold tweak.
