Canonical CI: grouped-tests.yml + root test/test_groups.toml

[ChrisRackauckas-Claude]

Summary

Converts the root Tests.yml from a hand-maintained version × os matrix (calling tests.yml@v1) into a thin caller of the canonical grouped-tests.yml@v1, with the test matrix declared once in test/test_groups.toml.

Changes

• .github/workflows/Tests.yml — the matrix test job is replaced by the canonical thin caller:

  jobs:
    tests:
      uses: "SciML/.github/.github/workflows/grouped-tests.yml@v1"
      secrets: "inherit"

  name:, on:, and concurrency: are preserved verbatim. No with: block is needed — every input matches the canonical default and the prior behavior (group env GROUP, check-bounds: yes, coverage on, coverage-directories: src,ext, no apt packages). Other workflows (Downgrade/FormatCheck/RunicSuggestions/SpellCheck/TagBot/DependabotAutoMerge) are untouched.
• test/test_groups.toml (new) — the matrix:

  [Core]
  versions = ["lts", "1", "pre"]
  os = ["ubuntu-latest", "windows-latest"]
  
  [QA]
  versions = ["lts", "1"]

• QA isolation (Category B) — this repo previously ran its QA-style checks (ExplicitImports, type-stability, AllocCheck allocation tests) inline under GROUP=="all"/"QA", with AllocCheck/ExplicitImports in the root test target. They are now refactored into a gated GROUP=="QA" path with an isolated environment:
  • test/qa/Project.toml — [deps] = AllocCheck + ExplicitImports + Test + LinearAlgebra + DASSL via [sources] path = "../.."; [compat] julia = "1.10".
  • test/qa/qa.jl — the moved QA testset (ExplicitImports, type-stability, alloc tests).
  • test/runtests.jl — Core/All run the functional suite; QA does Pkg.activate(test/qa) + Pkg.develop(path=repo root) + Pkg.instantiate() then includes qa.jl. Group dispatch updated to the canonical capitalized names (All/Core/QA).
• Project.toml — benign metadata fixes: dropped AllocCheck/ExplicitImports from the root [extras]/[targets] (now QA-isolated); added missing [compat] for the remaining extras (DAEProblemLibrary = "0.1", ModelingToolkit = "10, 11", Test = "1"). julia compat already at the 1.10 LTS floor.

Matrix match

Verified statically with scripts/compute_affected_sublibraries.jl --root-matrix (no tests/Aqua run locally — structural conversion only). Emitted set:

• Core: {lts, 1, pre} × {ubuntu-latest, windows-latest} = 6 cells → exactly reproduces the OLD functional version × os coverage.
• QA: {lts, 1} × {ubuntu-latest} = 2 cells → the QA checks (previously riding along on all 6 cells via the default GROUP=all) now run isolated on the canonical QA subset.

TOML + YAML parse and runtests.jl/qa.jl Julia-parse were verified statically.

Note

The QA group is newly wired as a separate CI job; its Aqua/JET (here: ExplicitImports + type-stability + AllocCheck) run in CI. Any failures will be triaged in a follow-up — no checks were skipped or silenced.

Ignore until reviewed by @ChrisRackauckas.
