Node.js 20 is deprecated. The following actions target Node.js 20 but are being forced to run on Node.js 24: actions/setup-dotnet@67a3573c9a986a3f9c594539f4ab511d57bb3ce9, actions/setup-java@cf277c60eb25467037889841efdb72551f06f6c3.

SONAR_TOKEN is not configured, so the three merge gates in docs/21-Quality-Gates.md §2.1 that depend on it — critical issues, duplicated lines on new code, and security hotspots reviewed — were not evaluated for this change. A green tick on this job means the gate was skipped, not that it passed. See CHECKLIST.md item WP-0.
