Stability checkpoint stable-v1.0.24 (svc) — Phase 4.2 wave continued: 26 unit tests for 4 quality report parsers (SpotBugs, PMD, Checkstyle, JaCoCo) using classpath fixture XML/CSV files at src/test/resources/META-INF/build-reports/. Pattern unblocks all parsers that were previously only smoke-tested. Coverage: each parser's totals + per-category aggregation + label mapping + edge cases (no-slash file path, malformed lines, default package). Cumulative svc Phase 4.2 across v1.0.21-24: 187 new tests across 20 test files. Post-merge main pipeline #703 SUCCESS.
