# pdftract-github-release WorkflowTemplate
#
# Orchestrates the final GitHub Release creation for a milestone tag.
# Runs after pdftract-build-binaries, pdftract-py-ci, pdftract-crates-publish,
# and pdftract-docker-build complete. Collects all release artifacts, computes
# the aggregate SHA256SUMS file, signs it with cosign (keyless OIDC), generates
# release notes via git-cliff, and creates the GitHub Release with all artifacts.
#
# Artifacts attached to the release:
# - 10 binary archives (5 triples × 2 feature variants)
# - 5 Python wheels + 1 sdist
# - SHA256SUMS (aggregate checksum)
# - SHA256SUMS.sig (cosign signature)
# - multiple.intoto.jsonl (SLSA L3 provenance)
# - pdftract-vX.Y.Z.cdx.json (CycloneDX SBOM)
#
# Pre-release tags (vX.Y.Z-rc.N) are marked as pre-release.

            ## Verifying this Release

            All artifacts are verified by a single signed checksum file using Sigstore keyless signing.

            ### Verify SHA256SUMS

            ```bash
            # Download the release artifacts
            gh release download {{workflow.parameters.tag}} --dir /tmp/pdftract-release

            # Verify individual artifacts against checksums
            sha256sum -c SHA256SUMS
            ```

            ### Verify Docker Images

            ```bash
            # Verify the main image
            cosign verify \
              --certificate-identity-regexp 'https://iad-ci-oidc.ardenone.com.*' \

            ```

            ### Verify SLSA Provenance (Binary Artifacts)

            ```bash

            gh release download {{workflow.parameters.tag}} --dir /tmp/pdftract-release

            cosign download attestation \

            # The attestation contains the full build provenance including:
            # - Source commit hash
            # - Builder identity (iad-ci Argo Workflows)
            # - Build parameters and materials
            # - Invocation metadata
            ```

            ### Verify CycloneDX SBOM

            ```bash
            # Download the release artifacts
            gh release download {{workflow.parameters.tag}} --dir /tmp/pdftract-release

            # Install cyclonedx-cli for validation
            go install github.com/CycloneDX/cyclonedx-cli/cmd/cyclonedx-cli@latest

            # Validate the SBOM schema
            cyclonedx-cli validate --input-file /tmp/pdftract-release/pdftract-v{{workflow.parameters.version}}.cdx.json

            # Scan the SBOM for vulnerabilities using grype
            grype sbom:/tmp/pdftract-release/pdftract-v{{workflow.parameters.version}}.cdx.json
            ```

            ### Download SBOM Attestation from Docker Image

            ```bash
            # Download the CycloneDX SBOM attestation from a Docker image
            cosign download attestation \
              --predicate-type https://cyclonedx.org/bom/v1.5 \
              ghcr.io/jedarden/pdftract:{{workflow.parameters.tag}} > sbom.json

            # The SBOM contains all transitive dependencies with:
            # - Component names and versions
            # - License information
            # - Hash digests for integrity verification
            # - Supplier and originator metadata
            ```

            The signatures and provenance are generated using Sigstore's keyless signing with OIDC from the iad-ci cluster (issuer: `https://iad-ci-oidc.ardenone.com`).
