What

In the reusable sublibrary CI workflow (.github/workflows/sublibrary-project-tests.yml, the lib/* project-model sublibrary tests), reformat the test job's name: so the per-job display name surfaces the Julia version in a clearer, distinguishing form.

The job name already interpolated the version as a parenthesized lowercase suffix ((julia ${{ matrix.version }})). This changes it to a / Julia <version> form so the GitHub checks list reads e.g. lib/OrdinaryDiffEqTsit5 / Julia 1.10 vs lib/OrdinaryDiffEqTsit5 / Julia 1, instead of distinct-version jobs being hard to tell apart.

Before / After (the only line changed)

Before:

name: "${{ matrix.project }}${{ matrix.group != 'Core' && format(' [{0}]', matrix.group) || '' }} (julia ${{ matrix.version }})"

After:

name: "${{ matrix.project }}${{ matrix.group != 'Core' && format(' [{0}]', matrix.group) || '' }} / Julia ${{ matrix.version }}"

Details

• Matrix variable carrying the Julia version is version, confirmed against both the workflow (matrix.version is also fed to julia-version:) and the matrix producer scripts/compute_affected_sublibraries.jl (--projects-matrix emits {"project":...,"group":...,"version":...,...}).
• The existing project and group axes in the name are preserved; only the version suffix format changed.
• Purely cosmetic: only the name: string changed — no functional/behavioral change.
• actionlint clean on the edited file.

Not touched

• sublibrary-downgrade.yml: its test job has no name: and its matrix only has a project axis — the Julia version is a single inputs.julia-version per run, not a per-job matrix distinguisher, so it is not the same multi-version-matrix situation. Left as-is.
• Non-sublibrary tests.yml / grouped-tests.yml: out of scope.

NOTE: v1 must be retagged after merge for @v1 callers to pick this up.

Real fix added (tests.yml leaf job name)

For reusable-workflow calls, GitHub displays the called workflow's job name in the checks list, overriding the caller's richer name. So the visible "Tests - " entries come from the leaf reusable SciML/.github/.github/workflows/tests.yml@v1 tests job name — not from the callers (grouped-tests.yml / sublibrary-project-tests.yml). Adding the version only to the callers has no visible effect.

This PR now also edits .github/workflows/tests.yml to append the Julia version to that leaf job name:

Before:

name: "Tests${{ inputs.group != '' && format(' - {0}', inputs.group) || '' }}"

After:

name: "Tests${{ inputs.group != '' && format(' - {0}', inputs.group) || '' }} (Julia ${{ inputs.julia-version }})"

inputs.julia-version is a real on.workflow_call.inputs input of tests.yml (default "1", type string). The checks list will now read e.g. Tests - Extended (Julia 1.10) / (Julia 1) / (Julia pre) distinctly. actionlint clean.

The sublibrary-project-tests.yml caller-name change in this PR is cosmetic (it is the caller job name, not what GitHub shows for reusable calls); kept as-is.
