ci(supply-chain): SBOM on every release + a verifier that reads the live registry (SUPPLY-001) - #118
Conversation
…ive registry SUPPLY-001. Adds CycloneDX + SPDX SBOM generation on `release: published`, and a zero-dependency harness that checks any PUBLISHED artifact for a provenance attestation and an SBOM. Measured against the live registries 2026-09-03: sdk 2.1.3, mcp-server 0.2.0 and adk 1.0.15 carry real SLSA provenance attestations, but NO release in any WAVE repo has ever carried an SBOM asset — including the two repos whose PROVENANCE.md declares `sbom: cyclonedx`. sbom.yml is deliberately separate from release.yml so the publish job holding `id-token: write` never also gains `contents: write`.

Running ultrareview automatically — This PR adds a new release-triggered SBOM workflow plus supply-chain verification scripts with security-sensitive URL validation and release-asset uploads; a subtle bug could break release integrity or falsely attest provenance, warranting deep multi-pass review.. I'll post findings when complete. |
Reviewer's GuideThis PR adds a least-privilege workflow that generates, validates, and attaches CycloneDX and SPDX SBOMs to each GitHub Release, plus a zero-dependency verifier that measures live npm/PyPI provenance and GitHub Release coverage with security-focused validation and offline tests. Reviewers should note that the verifier intentionally still reports failure until the workflow runs on a release and equivalent workflows land in the other repositories.

⚠️ Bug: SBOM check reads GitHub's 'latest release' without matching npm/PyPI version
In verify-supply-chain.mjs (lines 198-217), result.version is taken from the npm dist-tags.latest / PyPI info.version, but the SBOM check calls /repos/{repo}/releases/latest independently, with no comparison between rel.tag_name and result.version. The two 'latest' pointers can disagree (as shown in the PR's own evidence: npm sdk latest is 2.1.3 while gh release view shows v2.0.1 as the checked release) — so the SBOM gate can report a stale release's asset state as if it were the currently-published version's state, silently producing a wrong verdict for either a false PASS or false FAIL. Add a check that rel.tag_name corresponds to the resolved package version (e.g. derive expected tag from version and compare, or fetch the specific release by tag instead of /releases/latest), and surface a note when they diverge.

💡 Bug: CycloneDX validation accepts an empty components array
In validate-sbom.mjs, the SPDX check rejects an empty package list (!Array.isArray(spdx?.packages) || spdx.packages.length === 0, line 53), but the CycloneDX check only requires Array.isArray(cyclonedx?.components) (line 49) without checking length, so components: [] passes validation. This is exactly the 'worse than none' case the script is designed to catch (per its own docstring) but only catches it for SPDX, not CycloneDX. Add cyclonedx.components.length > 0 (or note explicitly if zero runtime deps is an accepted state) to close the asymmetry.

💡 Edge Case: versionFromTag regex has no end anchor, accepting trailing garbage
/^\d+\.\d+\.\d+/.test(version) in validate-sbom.mjs:26 lacks a $ anchor, so a tag like sdk-v2.1.3-whatever-extra-junk or malformed prerelease text still passes and the full unvalidated tail is used as version. Since this value only feeds strict string-equality checks in this file (not shell), it's not exploitable here, but it weakens the intended tag-format guardrail and could let a genuinely malformed tag slip through validate-sbom while still failing later comparisons confusingly. Consider anchoring to a stricter semver pattern (e.g. ^\d+\.\d+\.\d+(-[0-9A-Za-z.-]+)?(\+[0-9A-Za-z.-]+)?$) to reject obviously malformed tags earlier with a clearer error.

💡 Performance: No fetch timeout; one hung registry call blocks the whole verifier
getJson in verify-supply-chain.mjs (lines 136-147) calls fetch() with no AbortController/timeout. If registry.npmjs.org, pypi.org, or api.github.com hangs (rather than erroring), the CI job or local run will hang indefinitely rather than failing fast, since Node's default fetch has no built-in timeout. Add an AbortSignal.timeout(...) to the fetch call so a stalled registry produces a bounded, actionable failure instead of a hung job.

💡 Quality: First target failure aborts entire verification run
In main() (verify-supply-chain.mjs:276-283), the for loop over targets exits immediately on the first thrown error (e.g. a transient network failure for one package), returning exit code 2 without evaluating the remaining targets. For a multi-target evidence/gate script intended to report status across all artifacts, this means a single flaky target hides the pass/fail state of every other target in the same run. Consider collecting per-target errors and continuing, then reporting all results (with failed lookups marked distinctly) before returning the appropriate exit code.

💡 Quality: CLI entrypoints in both scripts are untested
Neither test file exercises the main() functions: verify-supply-chain.test.ts only tests exported pure functions and verifyTarget (never invokes CLI arg parsing, targets.json loading, or exit-code paths at verify-supply-chain.mjs:249-321), and validate-sbom.test.ts only tests versionFromTag/validateSboms, never the file-reading main() at validate-sbom.mjs:69-83. Since these entrypoints are what actually runs in CI (the sbom.yml workflow invokes validate-sbom.mjs directly, and the verifier is meant to run as a CLI gate), a bug in argument parsing or file I/O (e.g. wrong --targets path handling, TAG env fallback) would not be caught by the current suite. Add a couple of integration-style tests that invoke main() with temp files/mocked argv to cover the CLI glue.

…ctually holds Two defects found by checking the repo against its own history rather than its workflow file: 1. Every GitHub Release cut so far is named `v2.0.1`-style, while release.yml publishes on `sdk-v*`. The guard only accepted `sdk-v*`, so backfilling the ONLY existing release would have been refused. Accept both; versionFromTag already handled either. 2. The `case "$TAG" in v[0-9]*)` glob accepted `v1; rm -rf /` — the trailing `*` swallows the rest. Every use quotes "$TAG" so this was defence-in-depth rather than a live hole, but a guard that does not hold is not a guard. Replaced with a fully anchored semver regex. Also records that NO workflow in this repo creates a GitHub Release, so `release: published` fires only on a manual publish and workflow_dispatch is the load-bearing path today.

PyPI Integrity API PEP 740 per-file provenance endpoint project JSON urls provenance
💡 Result:
PyPI has implemented PEP 740 support through a new Integrity API, which provides programmatic access to per-file provenance and digital attestations [1][2]. The core endpoint for retrieving this information is: GET /integrity/{project}/{version}/{filename}/provenance [1][3] Key details regarding this endpoint and PEP 740 implementation include: 1. Endpoint Functionality: This endpoint returns a provenance object in JSON format, which contains one or more attestation bundles for a specific distribution file [1][3]. Each bundle includes the Trusted Publisher identity and a set of cryptographic attestations [4][3]. 2. Relationship to PEP 740: PEP 740 standardizes how digital attestations (such as SLSA provenance) are uploaded to and retrieved from a package index [5]. The index may optionally include a data-provenance attribute on file links or a provenance key in the file dictionary of its simple JSON API to point to these records [5]. 3. Data Format: The Integrity API is currently available only in JSON [1][3]. Consumers should extract and verify individual attestations from the returned provenance object [1]. 4. Project JSON URLs: While the Integrity API specifically serves provenance data for individual files, standard PyPI project metadata (including URLs) is accessed via the separate PyPI JSON API at /pypi/{project}/json or the Simple Index API [6][7]. Verified URLs associated with Trusted Publishers are displayed in the project metadata [8]. For practical verification, the pypi-attestations CLI tool is recommended for downloading and verifying artifacts against their provenance objects [4].

tag_name does not match that version. Add a regression test covering a
mismatched release tag.

SUPPLY-001 — provenance and SBOM on every published artifact
SUPPLY-001 was UNKNOWN on the GA gate: the release workflows were reported to have "the right broad shape", but nobody had produced evidence, and cross-repo coverage was unverified. This PR produces the evidence and closes the gap it found.
The defect, and how to reproduce it
Reading a workflow proves nothing about what is on a registry. A
release.ymlcontainingnpm publish --provenancesays what the next release will do; every version published before that workflow landed is still unattested. So I read the registries instead:Three findings, each with a receipt:
Provenance is genuinely working on three of five.
@wave-av/sdk@2.1.3,@wave-av/mcp-server@0.2.0and@wave-av/adk@1.0.15each carry a real SLSA attestation —dist.attestations.provenance.predicateType == "https://slsa.dev/provenance/v1", minted bynpm publish --provenanceunder OIDC trusted publishing. That half of SUPPLY-001 is in better shape than the gate assumed.The two provenance
NOs are historical, not workflow defects.@wave-av/cli@1.0.8was published2026-04-03T02:14:55Z, by hand;wave-av/cli'srelease.yml(which does carry--provenance) landed2026-09-03. PyPIwave-sdk 2.0.0was uploaded2026-04-03T02:00:42Z;sdk-python's OIDCrelease.ymllanded2026-09-03 17:07. Both are cured by the next tagged release. No code change is needed in either repo, and neither file is touched here — PR ci(issue-ops): enroll triage tier (Stage A) #17 and PR ci(sdk): gated public-release workflow on sdk-v* tags + 2.1.0-next.0 prerelease (#86) #41 own them.The real, universal gap: not one release in any WAVE repo has ever carried an SBOM asset.
gh release viewreturns zero assets forwave-av/sdk(v2.0.1),cli(v1.0.0),mcp-server(v0.1.2),adk(v1.0.6) andsdk-python(v1.0.0). Meanwhilemcp-server/PROVENANCE.md:10andadk/PROVENANCE.md:10both declaresbom: cyclonedx— a contract claim with nothing behind it.The fix
.github/workflows/sbom.yml(new) — onrelease: published, installs the locked tree and emits both documents with npm's nativenpm sbom(npm ≥ 10.4), then attaches them to the release. No third-party scanner to pin or trust.workflow_dispatchaccepts a tag so historical releases can be backfilled without cutting a version.It is deliberately a separate workflow rather than more steps in
release.yml, for two reasons. First, security:release.yml's publish job holdsid-token: write, and adding an SBOM upload there would widen that same job tocontents: writealongside the OIDC publishing credential — this keeps the publish job from ever gaining repo write, and this job from ever seeing the publishing identity. Second, contention: six open PRs (#115, #84, #74, #73, #57, #37) already touchrelease.yml; a new file composes with all of them instead of racing them.scripts/supply-chain/verify-supply-chain.mjs(new) — the harness above. Zero dependencies, no build step. Readsregistry.npmjs.org,pypi.organdapi.github.com; exits non-zero when any artifact misses the expectation declared intargets.json. It is a gate, not a report.scripts/supply-chain/validate-sbom.mjs(new) — fails the release closed on an SBOM that would be worse than none. An empty or version-mismatched document whose filename still matchessbom.*would make the verifier count the artifact as covered, laundering a gap into a pass. This asserts the CycloneDX root component version equals the tag and that the SPDX document lists at least one package.Security notes
No
${{ }}expression is interpolated into anyrun:block; the tag reaches bash only as a pre-validated environment variable, and is refused unless it matchessdk-v<semver>before it is passed togitorgh. Top-levelpermissions: contents: read, withcontents: writescoped to the single job that uploads. Package and repo identifiers are regex-validated before URL construction, so a malformedtargets.jsoncannot redirect a request at another host; a test asserts no request is made at all for a hostile name, and another assertsGITHUB_TOKENis never sent to a package registry.Proving tests
scripts/supply-chain/__tests__/— 30 vitest cases, offline, driven by fixtures that are trimmed copies of real registry responses captured 2026-09-03, so they pin the shapes the live services actually return.The workflow's generation and validation steps were executed for real against this tree, not just reasoned about:
Key coverage: a hand-published tarball that is registry-signed but unattested must not read as provenant (npm signs every tarball, so
dist.signaturesalone is not provenance); a non-SLSA predicate must not count; PyPI provenance requires every distributed file to be attested, not just the wheel; a repo with no GitHub Release is an SBOM gap rather than a crash.What this does not do
It does not make SUPPLY-001 pass. The verifier still exits 1, and will until (a) this workflow runs on a real release — it cannot run until a tag is pushed, so the SBOM half is implemented-but-unproven-in-CI here, and (b) the parallel repos get the same file. Those are listed as follow-ups rather than claimed.

.github/workflows/sbom.yml; releases return to carrying no SBOM asset.scripts/supply-chain/is inert — nothing imports it, no npm script references it (package.jsonis untouched; PRs #66 and #32 own it), and no existing workflow calls it, so it can be left in place or removed independently.

Medium Risk
The SBOM job uses scoped
contents: writeandGITHUB_TOKENfor release uploads; tag validation and split from publish reduce blast radius, but mis-tagged dispatch or cross-repo verifier assumptions could still attach wrong metadata.Overview
Implements SUPPLY-001 by adding release-time SBOM publication and offline/live tooling to prove provenance + SBOM against what is actually on npm, PyPI, and GitHub—not what workflows claim.
A new
sbom.ymlworkflow (kept separate fromrelease.ymlso the npm OIDC publish job never getscontents: write) runs onrelease: publishedorworkflow_dispatchwith a tag. It checks out the tagged commit, runsnpm ci, emits CycloneDX and SPDX SBOMs via nativenpm sbom --omit dev, runsvalidate-sbom.mjs, uploads assets withgh release upload --clobber, and verifies both files appear on the release. Tags are validated with a strict semver regex beforegit/ghuse.scripts/supply-chain/addsverify-supply-chain.mjs(reads live registries + latest GitHub Release assets pertargets.json, exit codes for gating),validate-sbom.mjs(rejects empty/mismatched SBOMs that would fake compliance), documentation, and Vitest coverage with fixtures from real registry shapes (SLSA vs registry-only npm signatures, full PyPI file attestation, SSRF guards on identifiers, token only to GitHub API).Reviewed by Cursor Bugbot for commit 5a35554.
