+`tests/check_fixture_release_manifest.sh` checks the complete portable fixture
+after real tool execution. It requires every canonical flow decision, portable
+tool identity, representative design input, both coverage classes, and the
+human-readable summary to be present in the generated release artifact.

 When editing workflow YAML or shell scripts, run `ci/check_flow_quality.sh`. It
 uses pinned ShellCheck and actionlint versions installed by
 `ci/install_ci_tools.sh`.
