 `sbom-diff-and-risk` is a local, deterministic CLI for comparing two SBOMs or dependency manifests and producing JSON plus Markdown reports.
 
 It uses conservative heuristics for change intelligence. By default it does not resolve CVEs, does not act as a reputation oracle, and does not perform hidden network enrichment.

+# sbom-diff-and-risk v1.0.0
+
+`v1.0.0` is the Policy Evidence release.
+
+The Python package metadata version for this tag is `1.0.0`.
+
+## Theme
+
+A stable, bounded release surface for dependency diff and local policy evidence.
+
+## Highlights
+
+- Provides minimal policy decision examples for `pass`, `warn`, `fail`, and
+  consumer-side `needs-review`.
+- Stabilizes `evidence_confidence` as `local_manifest_only`, `sbom_present`,
+  `policy_matched`, `provenance_recorded`, or `scorecard_recorded`.
+- Fixes one reviewer case from dependency diff to `new_package` policy warning
+  across JSON, Markdown, and SARIF artifacts.
+- Records policy match metadata in direct SARIF risk results, including the
+  local policy level and rule ID.
+- Keeps the three supply-chain non-claims visible: not a CVE scanner, not a
+  malware scanner, and not a package safety verdict engine.
+- Keeps the minimal GitHub Actions consumer path for running policy, uploading
+  `policy.json`, and enforcing the tool's exit code.
+
+## Release policy
+
+- `v1.0.0` is the stable GitHub Release contract.
+- GitHub Release assets are the distribution surface for this release.
+- Production PyPI publishing remains intentionally deferred.
+- The TestPyPI Trusted Publishing dry-run remains evidence of the test
+  publishing path only.
+
+## Compatibility and boundaries
+
+- Default analysis remains local-file based and deterministic.
+- No default network enrichment was added.
+- No CVE lookup, advisory resolution, malware scanning, or package safety
+  verdict was added.
+- Policy warnings and failures remain bounded local policy decisions.
+- `enrichment_recorded` was an rc label and is replaced by the more specific
+  `scorecard_recorded` label in the final contract.
+
+## Release evidence
+
+The tag-gated GitHub Actions workflow builds the wheel and source distribution,
+generates a SHA256 checksum manifest, records workflow artifact attestations,
+and publishes the same built files as GitHub Release assets. Final tags are
+explicitly marked as GitHub Latest; rc tags remain prereleases.
+
+Expected assets:
+
+- `sbom_diff_and_risk-1.0.0-py3-none-any.whl`
+- `sbom_diff_and_risk-1.0.0.tar.gz`
+- `sbom-diff-and-risk-SHA256SUMS.txt`
+
+Use `docs/verification.md`, `docs/release-provenance.md`, and
+`docs/self-provenance.md` for the correct verification path.

+## v1.0 release policy
+
+Chosen policy: publish `v1.0.0` as the stable GitHub Release contract while
+keeping production PyPI publishing deferred.
+
+For `v1.0.0`, stability applies to the CLI, report schemas, policy decision
+examples, evidence-confidence labels, reviewer case, and GitHub Release asset
+verification path. It does not claim production PyPI availability. Until the
+final tag is explicitly approved and created, `v1.0-rc.1` remains the current

+The tag workflow marks rc tags as prereleases and not Latest. It explicitly
+marks a final tag such as `v1.0.0` as GitHub Latest.

 Release assets produced by the updated workflow also include a deterministic SHA256 checksum manifest named `sbom-diff-and-risk-SHA256SUMS.txt`. The manifest is written with filenames sorted in a stable order. It is not a separate provenance system; it is a local byte-integrity check that helps reviewers confirm downloaded wheel and source distribution files match the hashes published with the same GitHub Release.
