-v0.5 PR 5 adds a production PyPI publishing decision gate. Production PyPI publishing remains deferred until the documented prerequisites are complete, dependency analysis stays local and deterministic by default, and CLI analysis behavior is unchanged.
+v0.5.0 is the GitHub Release for the production PyPI decision gate. The TestPyPI dry-run is completed, production PyPI publishing is intentionally deferred, dependency analysis stays local and deterministic by default, and CLI analysis behavior is unchanged.
 
 `sbom-diff-and-risk` is a local, deterministic CLI for comparing two SBOMs or dependency manifests and producing JSON plus Markdown reports.

+# v0.5.0
+
+Theme: production PyPI decision gate
+
+## Highlights
+
+- Added the production PyPI publishing decision gate for `sbom-diff-and-risk`.
+- Confirmed the intended production package name remains `sbom-diff-and-risk`.
+- Documented the future production publisher identity and workflow shape without enabling a production upload path.
+- Clarified that TestPyPI, GitHub workflow artifact attestations, GitHub Release asset verification, and PyPI Trusted Publishing provenance are separate trust surfaces.
+
+## Distribution status
+
+- TestPyPI dry-run completed; production PyPI intentionally deferred.
+- The TestPyPI package exists for version `0.4.1`.
+- The `v0.5.0` release is a GitHub Release and package version bump only.
+- No production PyPI workflow is added in this release.
+- No production PyPI upload is performed by this release.
+
+## Packaging and release alignment
+
+- Bumped the package version to `0.5.0`.
+- Synced `sbom_diff_risk.__version__` with the package metadata.
+- Updated sample SARIF metadata to report `0.5.0`.
+- Updated the README top-level release narrative for the v0.5.0 gate.
+
+## Not in this release
+
+- No analyzer features were added.
+- No SARIF behavior changes were added beyond sample metadata version alignment.
+- No policy behavior changes were added.
+- No hidden network behavior was added.
+- No production PyPI publishing path was enabled.

 The production gate is intentionally conservative because:
 
 - the production PyPI project does not currently exist under the intended name
-- the package metadata still declares version `0.4.1`
+- the package metadata has moved to `0.5.0` for the GitHub Release, but production PyPI publishing has not been enabled
 - the first production upload should be a deliberate release version, not an old dry-run version
 - the production PyPI pending publisher or trusted publisher has not been configured
 - the production GitHub environment has not yet been confirmed
