Correct dead platform declarations, stale rustdoc and test warnings; validate complete gettext headers. Install LLD in the Qt job and explicitly validate committed shader packs without rebaking them. Keep the independent shader bake gate and add three build-policy tests. The full local gate passed 2398 workspace tests and 715 Qt tests, QML audits, shader baking and the isolated offscreen smoke without compiler, rustdoc or gettext warnings. cx
