    # This used to ask for ${{ steps.artifact.outputs.coverage_report }},
    # which is set by the "Coverage Report name" step of run_tests -- a
    # different job. The steps context does not cross jobs, so that
    # expression evaluated to the empty string and the action fell back to
    # its documented behaviour for an unspecified name: "No input name,
    # artifact-ids or pattern filtered specified, downloading all
    # artifacts". It pulled down four, the two coverage reports and the two
    # test_reports bundles of JUnit XML, each into a directory named after
    # the artifact -- so the published site carried the test reports as well
    # as the coverage, under paths containing a run timestamp that changed
    # on every publish.
    #
    # merge-multiple puts the contents of both coverage artifacts directly
    # into coverage_report rather than under a directory named for each
    # artifact. Each one holds a single directory named for its suite,
    # ThreadX or SMP, renamed from default_build_coverage by the "Prepare
    # Coverage GitHub Pages" step, so the merge yields exactly the two
    # suite directories the deploy expects, and the artifact name -- with
    # its timestamp -- stops appearing in the published path at all.
    #
    # The two artifacts also each carry a default_build_coverage.xml, and
    # the merge means one overwrites the other. That file is consumed by
    # CodeCoverageSummary back in run_tests and is not read here, so this is
    # untidy rather than wrong.
