Bundle: ci-pipeline-cleanup, Phase 10 / frozen decision 0.9. Self-hosted alternative to Codecov / Coveralls. Posts a per-package coverage delta as a PR comment on every PR; updates the same comment in place on subsequent pushes (avoids duplicate noise). scripts/ci-guards/coverage-pr-comment.sh: - Reads coverage.out from the prior Go Test step - Builds per-package coverage table (mirrors check-coverage-thresholds averaging logic) - Searches existing PR comments for the '**Coverage report' marker and PATCHes the existing one if found, else POSTs a new one - No-op on non-PR builds (push to master, scheduled, etc.) Wired into go-build-and-test job after 'Upload Coverage Report' step with if: github.event_name == 'pull_request' guard. Operator can swap to Codecov/Coveralls later by replacing this script + step with a third-party action — the YAML manifest at .github/coverage-thresholds.yml stays unchanged either way.
