Description

Four of the five follow-ups #529 deferred, plus part of the fifth. Affects .github/workflows/supply-chain.yml's consumer-sbom job and adds two scripts/*.mjs with node --test siblings.

1. Pin the released package to its release tag. release.tag_name is <pkg>@X.Y.Z, so the one package a release names is installed at that exact version instead of resolving latest. That closes two real failures: the event fires immediately after npm publish, so a CDN-cached packument could stamp release 5.12.0 with an SBOM describing 5.11.1; and a re-run days later resolved a newer latest and produced a filename --clobber cannot replace, leaving the release permanently carrying two contradictory documents for the same package. The other three legs stay on latest — a release says nothing about them — which is why the decision is a script matching the tag to its matrix leg rather than an expression in YAML.

The pin buys a free assertion: --expect fails the job if the tree does not carry the version that was asked for. It also needs a retry, because pinning trades "resolves the wrong version" for "may not resolve at all" while the packument propagates — without it, the released leg, the one the release actually cares about, would be the one most likely to ship no SBOM.

2. Assert the documents are still a consumer closure. Nothing checked, so a syft, cataloger or exporter change shipped silently green. Deliberately not a count: 48c57d5 reverted exactly that, because live registry closures drift on somebody else's release and a false-red generator is the cry-wolf failure #391 and #525 already fixed. Instead: every catalogued entry must have come from the npm registry (a registry.npmjs.org download location in SPDX, a pkg:npm/ purl in CycloneDX), the package the document names must be in it at the stamped version, and a floor. That catches inflation by its cause rather than its size. The test sibling replays all three real regressions and pins the negative case that a closure which merely grew must still pass.

It runs on both documents and before the artifact is uploaded, so it is a gate rather than a detector — see the review round below for why both of those matter.

3. Move the install/stamp shell into scripts/ (rule 9) — partial, see below.

4. Build the artifact name once. Four occurrences collapse to one step output, and the two artifacts per leg become one carrying both formats.

5. Scan a lockfile-only directory rather than the consumer tree. syft walked every file under node_modules — thousands per leg, twice — to satisfy a cataloger that reads the root lockfile and nothing else. A copied directory rather than the lockfile as a file source; the review round explains why that distinction stopped being cosmetic.

What is deliberately NOT done

attach-sbom's upload branching is left inline. That job has no checkout and runs no repository code — which is precisely what makes it safe to give it contents: write, and why .github/CLAUDE.md's rule-10 inventory lists it under "genuinely API-only". Extracting its shell means adding a checkout and executing repository code beside a write-scoped token, which is a worse trade than the unit test it buys. Item 4 removes most of the reason that shell was fragile anyway. If the preference is to do it, it wants its own PR with a block harden-runner on that job.

Security review (`.github/CLAUDE.md`)

No allowlist grows. consumer-sbom gains a checkout, which reaches github.com, api.github.com and objects.githubusercontent.com — all already in that job's allowed-endpoints. harden-runner at block and its assertion are unchanged.
No permissions: change. consumer-sbom stays contents: read.
No model session is involved, so I1/I2 are not in play; no comment body, no posting identity.
Action SHAs: the new checkout is on the repo-wide pin. Both rule-1 greps are clean — the per-action grep returns one line (29 usages, one SHA) and the repo-wide dedupe grep returns no output.
The new checkout takes the EVENT ref, not ref: main, and this is the one judgement call worth arguing. verify-provenance pins main because it reads a verifier that must not come from the tag it is verifying. This job asserts a property of a document it just generated; there is no third party whose claim the checked-out code could be made to rubber-stamp, so that reasoning does not transfer. Pinning main would also make the only available verification — a dispatch on a branch — impossible, since the guard would be read from a main that does not have it yet. If you would rather have the main pin on release events specifically, ref: ${{ github.event_name == 'release' && 'main' || github.ref }} gets both at the cost of legibility.
Rule 9's bootstrap gap does not bite here: the jobs that check out the default branch are the ones in the AI pipeline, not this one.

Review round (CodeRabbit, Copilot, Claude deep review)

All findings addressed; the CycloneDX one turned out to be a live defect predating this PR.

Finding	From	Outcome
Missing required flags exit 1, but the header promises 2 for usage errors	CodeRabbit	Fixed (`c241137`). `parseArgs` owns required flags per mode. The test asserting the old behaviour sat directly under a comment saying the opposite.
The guard never requires the target package to be in its own closure	Copilot	Fixed (`c241137`). Asserted in both formats at the stamped version. The fixture that hid it omitted the target; both fixtures are now shaped after real artifacts.
Only SPDX is inspected; a CycloneDX regression ships unchecked	Copilot	Fixed, and see below — it was not hypothetical.
The guard detects but does not prevent publication	Claude deep review #1	Fixed (`d44f0a4`). See below.
Item 1 fixes the `--clobber` failure only for the released leg	Claude deep review #2	Accurate, pre-existing, unchanged. A release makes no claim about the other three.
The registry invariant could false-red on a legitimate git/tarball/alias runtime dep	Claude deep review #3	Latent, kept. Such a dependency is worth flagging on its own; the message now says so instead of inviting a reflexive widening.
The semver check was a PREFIX match, so `1.2.3garbage`, `1.2.3.4`, `01.2.3` passed a function whose error says otherwise	Copilot (2nd pass)	Fixed (`6f1b545`). semver.org's anchored grammar, prerelease and build metadata still admitted. See below — the fix had a trap in it.
The SPDX subject entry is exempted by name and never validated, unlike the CycloneDX one	Copilot (3rd pass)	Fixed (`1006b10`). Both formats resolve a subject and run the same assertions; a test pins the symmetry.
"Both are generated from the same syft run" — they are two separate `sbom-action` invocations	Copilot (3rd pass)	Fixed (`1006b10`). That distinction is the whole justification for reading both documents.
`pkg:npm/` is an ecosystem identifier, not a download origin — the CycloneDX check is not provenance	Copilot (4th pass)	Fixed (`9bb7aa7`). Correct, and the claim was mine. See below.
`--spdx`/`--cdx` are never enforced against the files' actual contents	Copilot (5th pass)	Fixed (`2217f70`). The flags were decoration: the same file passed twice satisfied everything. Detected format is now compared to the flag first.
`crossCheck` compared with `includes`, so duplicate inflation passed	Deep review r2	Fixed (`6bbe4b2`). Multiset comparison; duplicates within a document warn rather than fail, to avoid a false red.
Target check took the FIRST matching entry — a false red on multi-version closures	Copilot (6th pass)	Fixed (`6c75ca9`). Any matching entry satisfies it.
`normalize` keyed on array shape, so a document missing its format marker passed	Copilot (6th pass)	Fixed (`6c75ca9`). Requires `spdxVersion` / `bomFormat` too.
The files-array check rejected only absolute paths	Deep review r3	Fixed (`6c75ca9`). Rejects any path separator.
The guard is the second line against inflation, not the first	Deep review r3	Documented (`6c75ca9`). The scan shape is what prevents that class.
The rejection message re-introduced the value it rejected, forging Actions workflow commands	Copilot (7th pass)	Fixed (`db5d0c0`). See below.

The CycloneDX leak was already shipping

Chasing Copilot's finding turned up a type: file component named
/home/runner/work/_temp/consumer/package-lock.json in every CycloneDX consumer SBOM. This is the runner-path leak #529 fixed for SPDX, still live in the format nothing was reading — signed and attached to every release since.

Not introduced here. Run 32706731377, a scheduled run on main from before this branch existed, carries it in all four .cdx.json files. An intermediate commit on this branch claimed the branch had caused it; 7860c7e corrects that.

Cause: file metadata is cataloged independently of default-catalogers, so narrowing that to the lock cataloger never touched it, and the exporters named the artifact differently — SPDX a relative package-lock.json in its files array, CycloneDX the absolute path. Fixed with file.metadata.selection: none.

The guard is now a gate

sbom-action generates and uploads in one step, so the artifact existed before anything inspected it — and sign-sbom/attach-sbom deliberately do not require consumer-sbom to have succeeded. On a real release a rejected document would still have been signed and permanently attached while the run merely went red.

upload-artifact: false on both generators plus one explicit upload after the assertion closes it. This keeps #529's degradation rather than trading it away: a failed leg produces no artifact, the downstream globs expand to nothing, attach-sbom warns, and the repository SBOMs still ship. Gating those jobs on needs.consumer-sbom.result would have been worse — the matrix is fail-fast: false precisely so one bad leg cannot take the other three with it.

A guard that performed the attack while reporting it

assertVersion blocks a newline-bearing version from reaching $GITHUB_OUTPUT — then interpolated it verbatim into its own ::error:: complaint. A workflow command ends at a newline, so:

::error::version contains unexpected characters: "1.0.0
::error::FORGED COMMAND"

Line two is a live, attacker-authored workflow command. Reproduced before fixing. Both scripts now route untrusted values through a forLog helper (JSON.stringify), applied to everything sourced from a tarball, a generated document, or a release tag. The same class was already live in check-consumer-sbom.mjs, which reports entry names straight out of tarball-derived documents; fixed in the same pass. Tests assert the property — no message may contain a raw newline or a line starting ::.

The CycloneDX origin check was not what I said it was

pkg:npm/name@version is built by syft from the name and version alone; a CycloneDX document carries resolved nowhere — not in externalReferences, not in properties. Checked against a real component rather than reasoned about:

{ "name": "bulma", "version": "1.0.4", "purl": "pkg:npm/bulma@1.0.4",
  "properties": [ {"name": "syft:package:foundBy", "value": "javascript-lock-cataloger"},
                  {"name": "syft:location:0:path", "value": "/package-lock.json"} ] }

So that test is an ecosystem test. It catches a pkg:githubactions/… entry and a file component with no purl — the leak class it was added for — and a git, tarball, private-registry or aliased dependency passes it untouched. Describing it as provenance was the more serious half of the finding, and the claim was mine, not inherited.

Closed by a fourth assertion: the two documents must list the same name@version set. They are separate syft runs — precisely how the #529 leak lived in every CycloneDX document and no SPDX one — so this is a real check, and it carries the registry claim across: anything the weak purl test would admit must also appear in SPDX, where downloadLocation and the strong test are waiting. The script therefore takes both files in one invocation; two separate runs could each pass while disagreeing.

A test asserts that a git dep passes the CycloneDX check, so the asymmetry cannot be silently re-read as provenance later. Live agreement counts: 5 / 12 / 98 / 93.

Anchoring the semver check had a trap in it

Swapping the prefix regex for the anchored grammar made the character test unreachable — every string the grammar accepts is already within [0-9A-Za-z.+-]. That would have left the security-relevant check as dead code wearing the label of the control that matters most here (it is what stops a newline reaching $GITHUB_OUTPUT and syft's config heredoc).

The checks are therefore ordered character-test-first. Both stay live, and each error names the real problem: a value carrying a newline reports as an injection attempt rather than a formatting quibble. The tests assert which check catches which input — rejected-for-the-wrong-reason is exactly how the prefix bug survived the first review.

One more thing the heredoc was doing

The syft config heredoc is unquoted (it interpolates $PACKAGE/$VERSION), so an existing backticked phrase in a comment was being executed as a command and substituted away — the generated config read publishing without field. Inert inside a YAML comment; not inert in general. Backticks are gone from that heredoc, with a note saying why.

Verification

A green check on this PR proves nothing about any of it. consumer-sbom runs on release, schedule and workflow_dispatch only, so no PR exercises it. Every defect in #529 was found by dispatching and reading the generated JSON, never by a green job — so that is how this was verified.

Run 33265296155 (workflow_dispatch on this branch), green on all four legs. Artifacts downloaded and read:

package	closure	SPDX entries	CycloneDX entries
`@allxsmith/bestax-bulma`	5	7	6
`create-bestax`	12	14	13
`bestax-migrate`	98	100	99
`bestax-mcp`	93	95	94

CycloneDX carries one fewer entry because it states its subject in metadata.component rather than as a component. No absolute path in any document, in either format.

Both structural entries present in each document, source.name/source.version correct, no drift warnings, artifact filenames carrying the right version. The artifact store holds one archive per leg named bestax-consumer-sbom-<slug>-<version>, which still matches the bestax-*sbom* pattern sign-sbom and attach-sbom download by.

Locally: pnpm all exits 0; node --test "scripts/*.test.mjs" passes 640 tests.

What only dispatching found

Item 5 as specified in [CI] Follow-ups deferred from the consumer-closure SBOM (#529) #530 does not work as written. sbom-action prefixes whatever path receives with syft's dir: scheme, so pointing path at the lockfile fails with not a directory source on every leg — run 33260609524. The file input does take a file, but a file source made syft emit the scanned file as a component. Both dead ends are recorded in the workflow so nobody re-walks them; the shipped version copies the lockfile into an otherwise empty directory.
The CycloneDX leak, and that it predates the branch — neither visible without downloading and reading a .cdx.json, which nothing had done since ci: publish a consumer-closure SBOM per published package #529.
The header comment's bestax-mcp 94 (95) was never self-consistent — two structural entries cannot turn 94 into 95. The measured closure is 93. Corrected, and the block now cites the run it was measured from and states plainly that these are live registry closures which drift, so the next reader re-measures rather than trusting them. Nothing enforces the numbers, deliberately: pinning counts as a gate is what 48c57d5 reverted.

What this PR cannot verify

Item 1's pinned path fires only on a real release event, so no dispatch reaches it. Coverage is the unit tests on parseReleaseTag/installSpec — including the two-@ scoped-package case, which three of the four packages would hide, and a release naming a package outside the matrix.
sign-sbom and attach-sbom gate on github.event_name == 'release' and were skipped on the dispatch. Item 4's glob behaviour is verified by reading plus the ARTIFACT_PREFIX test, not by running — a further reason not to touch attach-sbom here.

Summary by CodeRabbit

New Features
- Consumer software bills of materials (SBOMs) are now generated in both SPDX and CycloneDX formats.
- Published SBOM artifacts include the installed package version and are grouped for easier retrieval.
Bug Fixes
- Improved package-version selection, installation retries, and release-version validation.
- Prevented generated SBOMs from including runner-specific filesystem paths.
- Added consistency checks for package identity, provenance, versions, and dependency closure across formats.
Tests
- Expanded validation coverage for malformed, inconsistent, and unsafe SBOM data.

Four of the five follow-ups #529 deferred (#530). Item 3 is deliberately partial; see below. 1. Pin the released package to its release tag. `release.tag_name` is `<pkg>@X.Y.Z`, so the one package a release names is now installed at that exact version instead of resolving `latest`. That closes two real failures: the event fires immediately after `npm publish`, so a CDN-cached packument could stamp release 5.12.0 with an SBOM describing 5.11.1; and a re-run days later resolved a newer `latest` and produced a filename `--clobber` cannot replace, leaving the release carrying two contradictory documents for the same package. The other three legs stay on `latest` — a release says nothing about them — which is why the decision is a script matching the tag to its matrix leg rather than an expression. The pin also buys a free assertion: `--expect` fails the job if the tree does not carry the version that was asked for. Pinning is retried, because it trades "resolves the wrong version" for "may not resolve at all" while the packument propagates. Without that, the released leg — the one the release cares about — would be the one most likely to ship no SBOM. 2. Assert the document is still a consumer closure. Nothing checked, so a syft, cataloger or exporter change shipped silently green. Deliberately not a count: 48c57d5 reverted exactly that, because live registry closures drift on somebody else's release and a false-red generator is the cry-wolf failure #391 and #525 already fixed. Instead every catalogued package must resolve to registry.npmjs.org, plus a floor. That catches inflation by its cause rather than its size, and replays both #529 regressions in the test sibling. 3. Move the install/stamp shell into scripts/ with node --test siblings (rule 9). The semver validation guards a value out of a published tarball that flows into $GITHUB_OUTPUT and syft's config heredoc, and there was no way to test it where it lived. This job now needs a checkout; it takes the event ref rather than `main`, because it asserts a property of a document it just generated rather than a third party's claim, and because `main` would make the only available verification — a dispatch on a branch — impossible. NOT done: extracting `attach-sbom`'s upload branching. That job has no checkout and runs no repository code, which is the whole reason it is safe to give it `contents: write`. Adding one to gain a unit test is a worse trade than the test is worth. #530 stays open for it. 4. Build the artifact name once. Four occurrences collapse to one step output. `sign-sbom` and `attach-sbom` glob these names from their own jobs and cannot read a step output across a job boundary, so this is four to one, not eight — what keeps those globs honest is that the prefix is now one exported constant pinned by a test. 5. Scan the lockfile rather than the tree. syft walked every file under node_modules — thousands per leg, twice — to satisfy a cataloger that only reads the root lockfile. The node_modules exclusion stays and is now structurally unnecessary rather than merely correct. None of this is exercised by a PR: the job runs on release, schedule and workflow_dispatch only. Verified by dispatch and by reading the generated documents, which is how every defect in #529 was found.

sbom-action prefixes `path` with syft's `dir:` scheme, so the lockfile pointed at it failed with `not a directory source` on every matrix leg. `file` is the input that takes one. Found by dispatch (33260609524), which is the only way this job is exercised at all.

bestax-mcp read 94 against 95 entries, which two structural entries can never produce. The measured closure is 93. Numbers now cite the run they came from and say plainly that they drift, so the next reader re-measures instead of trusting them.

Walkthrough

The consumer SBOM workflow checks out the event ref, selects and validates package versions, retries installation, scans a lockfile-only directory, validates SPDX and CycloneDX documents, compares their closures, and uploads both formats after validation. New scripts and tests cover metadata handling and dual-format SBOM inspection.

Changes

Consumer SBOM pipeline

Layer / File(s)	Summary
Installation metadata and artifact naming `scripts/consumer-sbom-meta.mjs`, `scripts/consumer-sbom-meta.test.mjs`	The metadata script selects release-pinned or `latest` install specifications, validates full SemVer values, reads installed versions, and emits artifact outputs. Tests cover CLI validation, exit codes, and log-safe diagnostics.
Dual-format SBOM inspection `scripts/check-consumer-sbom.mjs`, `scripts/check-consumer-sbom.test.mjs`	The validator normalizes SPDX and CycloneDX documents, checks npm registry provenance, target versions, subjects, distinct-package floors, path entries, and cross-format closure agreement. Tests cover malformed documents, duplicate identities, CLI errors, and message sanitization.
Workflow integration and guarded publication `.github/workflows/supply-chain.yml`	The workflow checks out the event ref, installs the selected specification with retries, scans a lockfile-only directory, disables file cataloging, validates both SBOM formats, and uploads one combined artifact per matrix leg.

Estimated code review effort: 5 (Critical) | ~100 minutes

Merge Risk: ⚪ Minimal · up to 5871b

The change validates and reproducibly publishes consumer SBOM artifacts without altering production runtime behavior or permissions; no actionable merge-blocking risk remains after normal checks and review.

Review details

Suppressed comments (2)

.github/workflows/supply-chain.yml:554

This validation happens after both sbom-action steps have already uploaded their artifacts (upload-artifact defaults to true). If the check fails, sign-sbom and attach-sbom still run because they require only the repository sbom result, download bestax-*sbom*, and therefore sign and publish the rejected consumer documents. Disable the action's automatic artifact upload and explicitly upload the two files only after this check succeeds so an assertion failure actually prevents publication.

      - name: Assert the document is still a consumer closure
        env:
          PACKAGE: ${{ matrix.package }}
          SLUG: ${{ matrix.slug }}
          BASENAME: ${{ steps.install.outputs.basename }}

scripts/check-consumer-sbom.mjs:142

The floor currently counts array entries, despite the comment saying it counts packages. A collapsed SBOM containing three copies of the same valid registry package satisfies catalogued.length >= 3; count distinct package identities (for example, (name, versionInfo)) so duplicate cataloger output cannot defeat the floor.

  // The floor counts catalogued packages, not entries. Counting entries would
  // let a document consisting only of the two structural names pass a floor of
  // two, which is exactly the collapse being guarded against.

+  const structural = structuralNames({ package: pkg, slug });
+  const catalogued = packages.filter(p => !structural.has(p?.name));


Valid — fixed in 8f2e0b3. The guard now asserts the target package is in its own closure at the version the stamp step recorded, in both formats.

The fixture was also unrealistic, which is how the gap hid: it omitted the target, but a real document does contain it (@allxsmith/bestax-bulma@5.11.4 with a registry download location, run 33262407242). Both fixtures are now shaped after the real artifacts, and there are two new negative cases — target absent, and target present at the wrong version, which catches the document and its filename disagreeing about which release they describe.

Correction: the commit is c241137, not 8f2e0b3 — I mistyped the SHA in the reply above. The change itself is as described.

allxsmith · 2026-08-29T16:17:09Z

This one was right, and chasing it found a live defect that predates the PR.

Checking the CycloneDX documents showed every one of them carrying a type: file component named /home/runner/work/_temp/consumer/package-lock.json — the runner-path leak #529 fixed for SPDX, still present in the format nothing was reading. Not introduced here: run 32706731377, a scheduled run on main from before this branch, has it in all four .cdx.json files. It has been shipping signed and attached since #529.

Cause: file metadata is cataloged independently of default-catalogers, so restricting that to the lock cataloger never touched it, and the two exporters named the artifact differently — SPDX a relative package-lock.json in its files array, CycloneDX the absolute path. Fixed with file.metadata.selection: none; verified gone in run 33262407242.

The guard reads both formats now, for exactly the reason you gave.

… path Addresses three review findings on #594, one of which turned out to be a live defect this branch introduced. The scan source is a lockfile-only DIRECTORY, not the lockfile as a file source. Passing it as sbom-action's `file` input worked and did remove the node_modules walk, but a file source makes syft emit the scanned file as a component: every CycloneDX document came out carrying `/home/runner/work/_temp/consumer/package-lock.json`. That is the runner-path leak #529 fixed for SPDX, reintroduced in the other format — and it was signed and attached. Copying the lockfile into an otherwise empty directory keeps the document shape #529 measured while still removing the walk. The guard now reads BOTH documents. An SPDX-only guard is what passed the leak above: the two come from separate sbom-action invocations, every .spdx.json was clean, and nothing looked at the .cdx.json that was not. CycloneDX states the same claims in its own vocabulary, so `pkg:npm/` purls stand in for registry.npmjs.org download locations and metadata.component carries the subject. The guard also asserts the target package is in its own closure at the stamped version. Without it, a wrong install spec or a cataloger dropping the direct dependency produces a well-formed closure OF SOMETHING ELSE and passes every other assertion. Missing required flags now exit 2 rather than 1. The header promised the codes stay distinct so a mistyped invocation is not reported as a supply-chain failure, and the checks were on the assertion path; parseArgs owns them now. The test asserting the old behaviour asserted it against a comment that said the opposite.

Deep review — 0 blocking · 3 advisory

#	Severity	Area	Finding	Location
1	🔵 Advisory	Robustness	The item-2 guard detects a bad closure but does not prevent its publication: the SBOM artifact is uploaded by the `sbom-action` step before the assert step runs, and `sign-sbom`/`attach-sbom` deliberately gate only on `needs.sbom.result == 'success'` — so on a real `release` a regressed/inflated consumer SBOM still gets signed and permanently attached while the run merely goes red.	`.github/workflows/supply-chain.yml:550`, `:592`, `:792`
2	🔵 Advisory	Correctness	Item 1's pin closes the CDN-staleness and re-run `--clobber` failures only for the released leg. The other three legs attached to that same release stay on `latest`, so a re-run days later can still resolve a newer `latest`, produce a new filename, and leave two contradictory consumer SBOMs for those packages on the release. Pre-existing, explicitly acknowledged in the PR; net improvement (1 of 4 fixed).	`scripts/consumer-sbom-meta.mjs:132`
3	🔵 Advisory	Robustness	The `registry.npmjs.org` invariant would false-red if a legitimate runtime transitive dependency ever resolves via a git / tarball / `npm:` aliased URL — a narrower reincarnation of the drift the count-based guard was reverted for (`48c57d5`). Verified 0 non-registry download locations across all four legs today (run 33260691933), so latent rather than active, and such a dep is arguably worth flagging.	`scripts/check-consumer-sbom.mjs:150`

Overall: The change is sound and unusually well-evidenced — I confirmed the failure shape (dispatch 33260609524 fails not a directory source on the path:-at-lockfile version) and the fix (dispatch 33260691933 green on all four legs with file:, 0 non-registry locations), traced the lastIndexOf('@') scoped-package logic and the assertVersion injection guard against their tests, and verified the checkout is on the repo-wide pin, carries persist-credentials: false, and is placed after the harden-runner assertion. The security reasoning in the PR body (event-ref vs main, no allowlist growth, contents: read unchanged) holds up. The riskiest thing to internalise is finding #1: the guard is a detector, not a gate — a maintainer must still act on a red release run, because the bad document ships regardless. That is a deliberate consequence of the attach/sign decoupling (repository SBOMs must ship even when consumer legs fail), so it is on the record rather than a blocker.

Residual risk — ways the addressed failure class (a silently-wrong consumer SBOM) could still occur:

Publication is not gated on the guard (finding #1): a cataloger/exporter regression still signs and attaches a bad document; the guard only reds the run. Refutation attempted and failed — sign-sbom/attach-sbom if blocks intentionally omit consumer-sbom from their success requirement, and the artifact upload precedes the assert step.
A non-registry runtime dep (finding #3) would flip the invariant from "catches inflation" to "false red on someone else's release" — the exact drift the count guard was reverted for. Refuted for today: dispatch shows every catalogued package under registry.npmjs.org; latent for the future.
Injection via the version string — refuted: assertVersion's anchored ^[0-9A-Za-z.+-]+$ test rejects newline/$/quote shapes (tests at consumer-sbom-meta.test.mjs:156), the value is "$SPEC"/"$EXPECT"-quoted into the shell, and the tag is repo-authored, not registry-authored.
Pinned-version mismatch — refuted: the --expect assertion fails the released leg if the tree carries a different version than the tag asked for (main returns 1; tested at :259).

🏄 Dude, this PR is clean — pins the gnarly released leg to its tag, guards the closure by its cause not its size, and the whole thing was surf-tested by real dispatch runs instead of trusting a green wave. Just remember the guard's a lifeguard whistle, not a net — it yells when the SBOM wipes out, it doesn't stop it from washing ashore on the release. Good to paddle out.

…ance The runner-path leak in the CycloneDX documents is NOT something this branch introduced, and the previous commit message said it was. Run 32706731377 — a scheduled run on main from before this branch existed — carries `/home/runner/work/_temp/consumer/package-lock.json` in all four .cdx.json files. It has been shipping in every release since #529, which fixed the same leak for SPDX and never looked at the other format. Switching to a file source moved which path was leaked; it did not create the leak. The cause is that file metadata is cataloged independently of `default-catalogers`, so restricting that to the lock cataloger never touched it. `file.metadata.selection: none` is what turns it off. The exporters disagreed about naming, which is why only one format showed it: SPDX writes a relative `package-lock.json` into its `files` array, CycloneDX writes a `type: file` component with the absolute path. Also drops backticks from the syft heredoc. It is unquoted — it interpolates $PACKAGE and $VERSION — so the existing "`files:`" in a comment was being run as a command and substituted away, leaving "publishing without field" in the generated config. Inert inside a YAML comment; not inert in general.

Deep review finding #1 on #594, and it was right. sbom-action generates and uploads in one step, so the artifact existed before anything had inspected it — and `sign-sbom`/`attach-sbom` deliberately do not require `consumer-sbom` to have succeeded. On a real release that meant a document the guard had already rejected still got signed and permanently attached to the release. The run went red and the bad SBOM shipped anyway, which is most of the value of the guard gone. `upload-artifact: false` on both generators plus one explicit upload after the assertion closes it: nothing is published unless both documents check out. This preserves the degradation #529 designed for rather than trading it away. A leg that fails for any reason now produces no artifact at all, the globs in the downstream jobs expand to nothing, and `attach-sbom` emits its ::warning:: while the repository SBOMs still ship. The alternative — gating those jobs on `needs.consumer-sbom.result` — would have been worse: the matrix is fail-fast: false precisely so one bad leg cannot take the other three with it, and a job-level gate would have done exactly that. Also makes the non-registry message say what to do when the entry is a legitimate git/tarball/alias runtime dependency rather than a leak (finding #3), so the next person to hit it decides about the dependency instead of reflexively widening the check.

The origin loop reads packages and components; SPDX keeps file entries in a separate `files` array that it never saw. syft writes those relative today — a bare `package-lock.json`, which leaks nothing and still passes — but that array is exactly where the absolute path would land if the file config changed, and an absolute path there is the SPDX shape of the leak that shipped in every .cdx.json from #529 until this branch. Checked rather than trusted to stay relative.

Round 6 — both fixed in 3b18658, verified in run 33267997287.

The floor counted entries, not distinct names. The good catch here is the interaction: duplicates are only warned about (npm can legitimately place a version at two paths), so three copies of the target package cleared a floor of three while the closure had collapsed to a single package — and symmetric copies also satisfy origin, target, subject and the multiset cross-check, so nothing else in the guard would have noticed. Distinct names is what "collapsed" actually means. Measured before tightening: the smallest real closure carries 5 distinct names, so the floor of 3 keeps its headroom, and there is a test pinning that a legitimate duplicate still passes.

Entries must now identify themselves. An entry with a plausible origin but no name produced no problem at all, and identities() rendered a missing version as ? — so when both syft runs omitted the same field, the floor and the cross-check agreed with each other and a malformed document shipped. Measured before requiring it: 428 entries across the four closures, none missing either field. Covered in both formats, plus the specific case where both documents omit the same metadata and still agree.

Deep review (0 blocking, 3 advisory) — no change. All three are trades already argued in the PR body and deliberately kept: the origin check's false-red exposure on a future non-registry runtime dep, the release-only paths being unexercisable by any PR or dispatch, and the three unpinned legs. Its note that a human should look first at the gate wiring and the artifact-name change is fair — those are the parts a green PR cannot exercise.

The second column is only the SPDX package count. CycloneDX stores the configured source in metadata.component, so it has one fewer component (6/13/99/94 in the verified shapes) rather than the two extra entries described here. Label the column as SPDX and state the CycloneDX difference so this measurement is not misread as applying to both published documents.

  # The first column is the closure; the second is what the document actually
  # contains, because the scan adds two entries that are not dependencies: the

  # syft emits as a package. Both are named so a reader can tell what they are,

#	Severity	Area	Finding	Location
1	🔵 Advisory	Robustness	The SPDX registry-origin invariant reds any leg whose published closure ever takes a git/tarball/alias runtime dep — kept deliberately, and it degrades (no consumer SBOM for that leg) rather than blocking the release.	`scripts/check-consumer-sbom.mjs:328`
2	🔵 Advisory	Security	`consumer-sbom` now checks out and executes repository code at the event ref (contents:read, harden-runner `block`); the trust rests entirely on release tags being creatable only by release automation.	`.github/workflows/supply-chain.yml:239`
3	🔵 Advisory	Coverage	The pinned-install path (`installSpec` release branch + `--expect` tree assertion) fires only on a real `release` event, so it is covered by unit tests alone and never exercised end-to-end — as the PR states.	`scripts/consumer-sbom-meta.mjs:152`

Overall: This is a sound, unusually well-verified change. I read both scripts in full, both node --test siblings, and traced the workflow wiring (checkout → spec → install/stamp → generate → gate → upload) plus the downstream sign-sbom/attach-sbom globs. The gate ordering is correct — upload-artifact: false on both generators with a single explicit upload after the assertion makes it a genuine pre-publication gate, and the new single-artifact-per-leg name (bestax-consumer-sbom-<slug>-<version>) still matches the bestax-*sbom* download pattern while leaving the inner .spdx.json/.cdx.json filenames — and thus the signing globs — untouched. Format/flag cross-checking, multiset agreement, the forLog log-injection defense, distinct-name floor, and the two-@ scoped-tag split are all handled and tested. The riskiest part for a human to weigh is advisory #2: this job went from running no repository code to executing event-ref code, which the PR argues (correctly, since the guard validates a document it just generated and a malicious tagger already owns the release) — but it is the one new trust surface, so confirm you accept the reasoning rather than the diff. I could not run the suite here (node execution is blocked in this sandbox); verification rests on static analysis against run 33265296155's reported results in the PR body.

Residual risk:

Inflation slipping through the guard — refuted for the leak class it targets: a CycloneDX type: file path leak fails the origin check (no pkg:npm/ purl) and the cross-check, and is prevented at source by file.metadata.selection: none; the SPDX files[] path check rejects any separator, not just absolute. The genuinely uncatchable case (a real npm package resolving from the registry and present in both docs) is bounded by the lockfile-only scan shape, which is documented as the first line rather than this guard.
False-red breaking a release — largely refuted: sign-sbom/attach-sbom gate only on needs.sbom.result == 'success' and consumer-sbom is fail-fast: false, so a leg reddening for any reason (origin false-positive, transient 404 after 3 retries) degrades to "no consumer SBOM attached + ::warning::" while the release and its repository SBOMs still ship.
Silent disabling of the pin — refuted: spec now requires --event and exits 2 (usage) rather than resolving latest, with a test pinning that; and --expect fails the stamp if the tree disagrees with the pinned version.

🏄 Whoa, this PR paddled out through like sixteen sets of review waves and came back styling — the gate closes clean, the log-injection barrel got shut down, and every gnarly edge is written up in the comments instead of left to wipe someone out later. Ship it, brah.

Round 7. Both parsers accepted any dashed option and silently ignored it, which in this script is not a usability wart but another silent-disable path — the third found on this branch. Every optional flag here turns a safeguard OFF by being absent, so a typo that is ignored exits 0 having disabled it: --tagg a release leg resolves `latest` — the pin item 1 exists to add simply does not happen --exepct the installed-version assertion is skipped Both now fail, naming the flags the mode does accept. A flag valid for the other mode is rejected too, since `spec --dir` is as wrong as `spec --tagg`. Fixed in check-consumer-sbom.mjs in the same pass, though Copilot only named the sibling. No flag there is optional today, so a typo would currently be caught by the required check — but that is a property of today's flag list rather than a guarantee, and the first optional flag added would reopen it silently. Round 5 is the precedent for sweeping the sibling rather than waiting for it to be reported separately. Deep review's three advisories need no change; all are documented trades. Its #2 is worth a maintainer's explicit nod rather than a diff read: this job went from running no repository code to executing event-ref code, which is the one genuinely new trust surface in this PR.

allxsmith · 2026-08-29T18:35:02Z

Round 7 — fixed in 5871b31, verified in run 33268591176. The strict parser also confirms the empty --tag "" that schedule and dispatch pass is still accepted.

This is the third silent-disable path found on this branch, and that pattern is now the more interesting finding than any individual instance. Every optional flag in this script turns a safeguard OFF by being absent, so a parser that ignores unknown options converts a typo into a disabled control that exits 0: --tagg means a release leg resolves latest — the pin item 1 exists to add simply does not happen — and --exepct skips the installed-version assertion. Both now fail, naming the flags the mode accepts, and a flag valid for the other mode is rejected too.

Fixed in check-consumer-sbom.mjs as well, though you only named the sibling. No flag there is optional today, so a typo would currently be caught by the required check — but that is a property of today's flag list rather than a guarantee, and the first optional flag added would reopen it silently. Round 5 is the precedent for sweeping the sibling rather than waiting for it to be reported separately.

Deep review (0 blocking, 3 advisory) — no change; all three are documented trades. Its #2 deserves an explicit decision rather than a diff read, and I want to surface it rather than let it sit in a table: this job went from running no repository code at all to executing event-ref code. The reasoning is in the PR body and beside the step, and I believe it holds — the guard validates a document it just generated, and anyone who can create a release tag already owns the release. But it is the one genuinely new trust surface here, and it is the kind of change .github/CLAUDE.md says should be argued rather than waved through.

Deep review — 0 blocking · 4 advisory

#	Severity	Area	Finding	Location
1	🔵 Advisory	Security	The new `checkout` on the event ref makes `consumer-sbom` go from running no repository code to executing branch-authored code beside its (read-scoped) token — the one genuinely new trust surface here. Sound as argued, but the deliberate `main`-vs-event-ref call deserves the maintainer's explicit nod.	`.github/workflows/supply-chain.yml:74`
2	🔵 Advisory	Correctness	The SPDX registry-origin check will false-red on a legitimate future runtime dep resolving from git/tarball/`npm:` alias. Intentional and now well-messaged ("decide whether to keep the dependency before widening"), but it means a good release can red on a dependency choice nobody flagged.	`scripts/check-consumer-sbom.mjs:328`
3	🔵 Advisory	Coverage	The pinned-install path (`installSpec` on a `release` event) is unreachable by any PR or dispatch, so its only coverage is the unit tests — including the two-`@` scoped case. Real `release`-event behavior ships unverified-by-run, as the PR states.	`scripts/consumer-sbom-meta.mjs:152`
4	🔵 Advisory	Robustness	The target/subject/cross-check assertions assume syft emits the full scoped name (`@allxsmith/bestax-bulma`) in CycloneDX `component.name` rather than splitting it into `group`+`name`. Empirically true today (green dispatch 33265296155; fixtures shaped after real docs), and a divergence fails red (safe), but it is an undocumented dependence on syft's CycloneDX shape.	`scripts/check-consumer-sbom.mjs:353`

Overall: The change is sound and unusually well-defended — I could not find a residual instance of the failure class it addresses that survives its own assertions. The riskiest part is the one the PR itself flags as needing a human nod (advisory #1): consumer-sbom now executes event-ref repository code, which is a new capability for that job even though its token stays contents: read and the checkout runs persist-credentials: false on the repo-wide pin. Everything else — the gate-not-detector upload ordering, the both-formats cross-check, the forLog sweep, the character-then-semver ordering, the distinct-name floor — checks out against the code and the tests. Focus first on whether the event-ref checkout trade is acceptable to you; the rest is refinement already argued in the body.

Residual risk: the failure class is SBOM inflation / provenance drift, and I chased the ways it could still occur:

A genuine npm dep resolving from registry, present identically in both docs, would pass every assertion — refuted as a guard gap because the PR correctly identifies the scan shape (a directory holding only the root lockfile) as the actual control and documents that the guard is the second line, not the first. Verified: path: points at ${{ runner.temp }}/scan, populated only by cp package-lock.json (supply-chain.yml:421-422), with file.metadata.selection: none and exclude: ./node_modules/**.
Format-specific inflation (the #529 CycloneDX runner-path leak shape) — refuted: inspect runs on both normalized documents, the CycloneDX type: file leak lands in components with no pkg:npm/ purl and fails origin, and crossCheck compares the two as multisets so a single-format extra reds. Tests rejects the runner-path file component… and the same-closure check is what stops the weak purl test being a hole exercise exactly this.
Wrong-version / wrong-package closure — refuted: target-in-own-closure, any-matching-version, subject-in-both-formats, and the --expect tree assertion all cover it; the multi-version-and-nested-copy false-red is specifically tested (a closure carrying two versions of the target is not a mismatch).

🏄 Dude, this one's been surfed clean — seven review sets have already waxed every rail, the gnarly log-injection and phantom-path wipeouts are patched, and the guard actually gates the wave instead of just filming it. Only thing left is for the head lifeguard to bless that fresh event-ref checkout. Paddle it out. 🌊

#	Severity	Area	Finding	Location
1	🔵 Advisory	Security	The new `checkout` takes the event ref, so on a real `release` it runs the tag's copy of the two scripts rather than `main`'s. Argued in the PR; low risk (tag is maintainer-created, job is `contents: read` + harden-runner `block`, and it only re-asserts a property of a document it just generated). On the record.	`.github/workflows/supply-chain.yml:239`
2	🔵 Advisory	Coverage	Item 1's pinned-install path and item 4's sign/attach glob compatibility fire only on a real `release` event — no PR or `workflow_dispatch` reaches them. Coverage rests on the unit tests + reading. I verified the artifact-name→glob path by inspection (see residual risk) and it holds.	`scripts/consumer-sbom-meta.mjs:152`
3	🔵 Advisory	Robustness	The guard is explicitly the second line against inflation; a genuine npm-registry transitive dep that appears in both documents passes origin, floor and cross-check. The first line is the scan-shape (lockfile-only dir). Documented at length in the script header — noted so a future reader does not weaken the scan on the belief the guard covers it.	`scripts/check-consumer-sbom.mjs:546`

Overall: This is a careful, unusually well-documented CI change and it is good to go. I ran both node --test siblings (78/78 pass) and exercised the guard against the real regression fixtures (github-actions entry, doubled catalogers, runner-path file: component, wrong-version, format/flag mismatch, injection strings) — every one is rejected for the right reason, and a merely-grown closure passes. The riskiest surfaces are the two paths no PR can exercise (the release-only pin and the sign/attach globs); I confirmed by reading that the single-artifact-per-leg rename keeps merge-multiple: true + nullglob producing the identical flat file layout the downstream globs already expect, and that ARTIFACT_PREFIX is pinned by a test. The maintainer's attention is best spent confirming they accept advisory #1 (the event-ref checkout on release).

Residual risk — ways the addressed failure class (SBOM inflation / runner-path leak / wrong-version stamp) could still occur:

Format-name mismatch for a scoped package (CycloneDX group+name split would false-red the cross-check): refuted — the dispatch run in the PR body shows @allxsmith/bestax-bulma agreeing across both formats (5/5), so syft emits the full scoped name in both; the empirical evidence rules this out.
A new legit registry dependency inflating the closure: not covered by the guard by design (advisory #3) — the scan-shape is what prevents it; origin/floor/cross-check deliberately allow growth to avoid the cry-wolf false-red that 48c57d5/#391/#525 reverted.
A leaked path escaping the files-array check: refuted — the check now rejects any separator (/ or \) after stripping a leading ./, and the CycloneDX type: file variant is independently caught by the origin/no-version assertions (verified against the reproduced fixture).

🏄 Gnarly-deep swell on this one, dude — every wave (leak, forged ::error::, dead-code semver, count-vs-name floor) already got surfed and pinned to a test before I paddled out. Clean barrel, no wipeouts. Send it. 🌊

Checklist

Review round (CodeRabbit, Copilot, Claude deep review)

The CycloneDX leak was already shipping

The guard is now a gate

A guard that performed the attack while reporting it

The CycloneDX origin check was not what I said it was

Anchoring the semver check had a trap in it

One more thing the heredoc was doing

Verification

What only dispatching found
