Adds sbom.yml (workflow_call) invoked from pipeline.yml after build-image and build-helm-chart. Generates CycloneDX + SPDX for the container image, CycloneDX for the source tree (post dotnet restore), and CycloneDX for the Helm chart tgz. All four SBOMs are published as GitHub Release assets. Drivers: customer procurement requirements and EO 14028 / EU CRA compliance. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
- release-public: require generate-sbom.result == 'success' so a skipped SBOM job (dependabot actor, etc.) cannot proceed to download a non-existent artifact and block the release - setup-dotnet: add cache: 'nuget' to avoid re-downloading the full NuGet closure on every run - Install Syft: replace curl|sh with anchore/sbom-action/download-syft (SHA-pinned composite action) for verified binary installation - Generate Source SBOM: exclude .git/.github from the scan and add a comment noting project.assets.json provides transitive NuGet deps - Generate Helm Chart SBOM: replace fragile ls|head -1 with a bash array glob and an explicit existence check for a clearer failure message Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
