 - Push validation open-PR detection is now POSIX-shell compatible (no bash-only `pipefail`/array/`[[ ... ]]` usage), fixing failures on runners that execute `run` scripts with `/bin/sh`.
 - PR validation now checks that `coverage.out` exists before invoking `coverage-badge`; when missing, badge upload is skipped with a summary note instead of failing the workflow.
 - PR decoration is now `continue-on-error` to avoid hard-failing validation when the external `decorate-pr` action's internal extractor step is unavailable.
+- PR validation now skips external PR decoration on non-GitHub runners and writes a summary note instead, avoiding runner-specific action resolution failures.
+- Coverage summary generation is now resilient when badge outputs or `coverage-packages.md` are unavailable, preventing summary-step hard failures after earlier skips.
 - README badge link target updated to `actions/runs/latest?workflow=...` format per workflow standards.
 - CI security scanning now uses GitHub Marketplace actions (`securego/gosec` and `golang/govulncheck-action`) instead of manual tool installation, improving reliability and caching.
 - CI setup compatibility fix: gosec scanner now references the correct public action source (`securego/gosec`), resolving action clone failures in Gitea runners.
