A repository at /home/interview/repo contains a multi-component application with infrastructure code in the /infra directory and documentation in the /docs directory. Currently, the repository has no automated workflow configured with path-based filtering to run workflows only when specific files change. A starter workflow file has been created at .github/workflows/infra-check.yml with the basic structure. The repository has the upload-artifact action available locally at .github/actions/upload-artifact for artifact management.
Navigate to /home/interview/repo and complete the GitHub Actions workflow at .github/workflows/infra-check.yml that runs only when files under the /infra directory change. The workflow should trigger on push events, use container image (node:20-slim), run a validation script at ./validate-infra.sh, and create an artifact named "validation-report" containing validation-result.txt using ./.github/actions/upload-artifact. The workflow can be tested with ./github-ci push and artifacts will be available in /tmp/github-artifacts/1/ for verification.
