Pull request overview
Updates the release workflow to avoid mutating GitHub Releases by removing post-creation SBOM asset uploads and retaining SBOMs only as Actions artifacts.
Changes:
- Removed the
gh release uploadstep that attached SBOM files to an already-created GitHub Release. - Increased SBOM Actions artifact retention from 7 to 90 days.
- Regenerated the compiled workflow lockfile (
release.lock.yml) to reflect the template changes.

PR description/title state the GitHub release is “immutable” and “never modified again”, but this workflow still instructs updating the release post-creation via the update_release MCP tool (see update_release instructions later in this file). That means the release metadata/body is still mutated after creation; only the artifact set is. Please clarify the PR wording (e.g., “no post-creation asset uploads” / “release assets immutable”) or, if true immutability is required, stop updating the release after gh release create and publish highlights elsewhere (e.g., as an artifact or discussion).

This lockfile reflects removal of gh release upload, but the overall workflow still updates the release after creation via the update_release safe-output tool. If the PR’s intent is true release immutability, the workflow should avoid any post-create release updates; otherwise, please adjust the PR title/description to specify “no post-creation asset uploads” rather than “release immutable”.
Summary
Makes the GitHub release immutable by ensuring no artifacts are uploaded to it after creation.

Before: The release was created with binaries, then SBOM files were uploaded as a separate
gh release uploadcall — modifying the release after creation.After: The release is created once with binaries and is never modified again. SBOM files are generated post-release and uploaded exclusively as GitHub Actions artifacts (
sbom-artifacts).
