A failing test threw away coverage that had already been collected, and the run whose behaviour changed is exactly the run whose coverage is worth reading. Measured on the failing run of 2026-08-18: it uploaded test_reports for all three suites and no coverage_report artifact at all. Two causes, and the workflow one is the smaller of them. cmake_bootstrap.sh runs under set -e, so a failing ctest aborted test() before ./coverage.sh was reached. The gcda files exist by that point, so nothing was missing except the step that reads them. ctest's status is now captured and returned at the end, and the summary grep is allowed to fail rather than being the thing that stops the coverage behind it. The serial branch of the test dispatch collected no status either, so under set -e the first failing configuration stopped the remaining four from being tested at all -- and their coverage from being collected. That was cheap while the suites ran in parallel, because the parallel branch already collects exit codes from its background jobs. Moving to serial execution in #643 quietly made one failure cost the other four configurations. The serial branch now collects status the same way the parallel branch does. With those fixed the report exists, so the workflow steps that publish it no longer skip on failure. They are guarded with !cancelled() rather than always(), so a cancelled run still stops promptly, which is the idiom deploy_code_coverage already uses. The ${{ }} wrapping is required and not decoration: a bare ! opens a YAML tag, and the file will not parse without it. Verified locally by replacing one test binary with a stub that exits 1: before the failing run of 2026-08-18 produced no coverage_report artifact after run.sh test default_build_coverage exits 8, and produces coverage_report/default_build_coverage.xml with 177 files and 3804 of 3827 lines after run.sh test all exits 8, and all five configurations run rather than stopping at the first The failure still fails. Only the reporting around it changed. Assisted-by: Claude Opus 5 <noreply@anthropic.com>
