Run build_metadata_r5.py --workspace <reviewed workspace> --output <fresh path under installation/reload-fixes-20261030>. Requires immutable r4-final archives and own build_bundle.py ZIP helpers. This revision compiles no classes: every production class and implementation source is preserved. Run test_metadata_r5.py against current installed originals for native dependency/discovery and JER checks. Test files are not included in the production JAR.
