feat(sbom): emit package origin and preserve ingested assertions#391bomly-guy wants to merge 23 commits into
Conversation
Issue #380 asked for per-component supplier and description sourced from deps.dev during --enrich. Probing the live API across npm, PyPI, Maven, NuGet, Cargo, and Go shows GetVersion asserts neither field: it carries only links[] and registries[]. A description exists only on the separate project endpoint, where it is the source repository's description, so every package in a monorepo would receive the same text. Deriving supplier or description for third-party packages needs registry-native metadata Bomly does not fetch, which would mean new allowed network hosts. Those two fields are therefore deferred, and this change ships what needs no new source: metadata Bomly already collects and then dropped at the export boundary, plus assertions a third party made in an SBOM Bomly ingests. Nothing is invented. Package origin. ResolvedURL is not a URL. npm/pnpm/yarn/bun record the exact tarball, Bundler records the GEM registry root, Cargo records a registry+/sparse+/git+ prefixed index or repo, swiftpm records a repository, and uv, pipenv, pub, and npm link entries can all record a local filesystem path. internal/sbom/locator.go classifies each value into artifact / VCS / registry-root / nothing before it can reach a document. Two rules are load-bearing: an http(s) scheme is required and userinfo is rejected, which keeps build-machine paths and private registry tokens out of published output; and a registry root never becomes a download location, because that failure would be silent and plausible rather than caught by a validator. Round-trip preservation. Ingest is not decode-then-encode: ToGraph converts to an sdk.Graph and export rebuilds a fresh document, so supplier, description, and external references were lost by a format conversion even though both decoders could see them. They now ride Dependency.Metadata under bomly.sbom.* keys, following the SetDetectionLicenses precedent, with no SDK contract change. ToGraph deliberately does not set Dependency.Source, which feeds RegistryMatchEligible and would quietly break scan --sbom --enrich. Also fixes two pre-existing gaps found by the new round-trip tests: FromDepGraph never read pkg.CPEs, and ToGraph dropped CPEs and digests. The two new fuzz targets found four real bugs while being written: an "@revision" suffix re-parsing as userinfo on a path-less URL, a control character reaching that suffix, an invalid percent-escape from a dot-containing non-hostname, and a scheme with no host. Verified with make test, make generate (no drift), make fuzz, and a new smoke case. Both formats validate against spdxlib.ValidateDocument and the CycloneDX 1.7 schema; real scans across npm/ruby/rust/python/go leak no local paths.

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The change emits package origins and preserves imported SBOM assertions, but the current implementation can still publish credential-bearing URL data, lose VCS revision information, discard vulnerability assertions during duplicate merges, and drop hashes from some references. These issues can produce sensitive or materially incorrect SBOM output, so the PR is not safe to merge until addressed. Sequence Diagram(s)sequenceDiagram

The comment states that the temp dir stands in for any local path the detectors saw.

Review found the safety gate had two holes, both of which could put a
credential or a local path into a published document.
Credentials outside userinfo. Signed and private-registry links carry
them as query parameters ("?token=", "?X-Amz-Signature="), which the
userinfo check did not see and parsed.String() re-emitted verbatim. A
benign query parameter cannot be told apart from a credential, so any
query or fragment now disqualifies a non-VCS locator. VCS locators stay
exempt because normalizeVCS already discards both and keeps only a
character-checked revision.
Ingested URLs bypassed the gate entirely. A CycloneDX `vcs` reference,
an SPDX PackageHomePage, and every passthrough external reference were
stored raw and re-emitted, so a hostile or careless source document
could launder a file:// path or an embedded credential into Bomly's
output. Ingest is untrusted input and now passes the same checks a
lockfile value does.
Also from review:
- Ingested VCS URLs are normalized to the SPDX git+ form. They become
PackageDownloadLocation directly, where a bare https URL made a
repository look like an ordinary package download.
- SPDX PackageDownloadLocation is no longer re-classified by path shape.
The field already asserts a download location, so an exact endpoint
without an archive suffix was being demoted to a registry root and
re-exported as NOASSERTION.
- SHA3-256/384/512 survive ingest. Stripping every hyphen produced
"sha3256", which neither encoder matches, silently dropping the
checksum.
- SPDX PackageHomePage is restored on export; it was decoded but never
re-emitted, so an SPDX-to-SPDX pass dropped a field SPDX represents
exactly.
- Scorecard repository no longer overwrites an ingested one, matching
the documented ingest-wins precedence, and is suppressed in SPDX
PackageSourceInfo when a detector VCS location is already emitted, so
one package cannot assert two different source repositories.
- CycloneDX supplier URLs are preserved rather than flattened to a name.
- cpe22Type references are accepted on ingest alongside cpe23Type.
- The Component locator comment no longer claims at most one of
ArtifactURL/VCSURL is set; an ingested document can assert both.
- The smoke leak check no longer relies on the output directory, which
would miss a leak of the separate bomly-git-* clone path.

The credential gate added in the previous commit was placed above the source-based VCS classification, so only cargo's explicit "git+" prefix reached normalizeVCS. A git dependency that pins its revision the usual way — "https://host/repo.git?rev=<sha>", a DependencySourceGit URL, or a swiftpm pin — was dropped by the gate instead of normalized, losing a valid revision assertion. The code comment claimed VCS locators were exempt while the ordering made that false for most of them. Every VCS form is now classified first. That is safe because normalizeVCS discards the query and fragment outright and keeps only a character-checked revision, so a credential in either position still cannot survive: "?token=s3cret" on a git URL yields the bare repository locator. Added table cases for all four VCS shapes, including the credential case, so the ordering cannot silently regress. Also from review: - mailto references rejected fragments nowhere, so "mailto:security@example.com#token=<secret>" was re-emitted verbatim as a supplier URL or external reference. isPublishableReferenceURL now requires an empty fragment, with a dedicated unit table. - The hostile-ingest fixture carried its secrets only in a query, where the query gate could mask a missing fragment check. It now carries a distinct unique secret per position — query, fragment, and mailto fragment — so no one gate can hide another's absence. Verified by reverting the mailto guard and confirming the test fails. - The SHA3-256 round-trip assertion checked only the checksum count, which would not notice the algorithm degrading to another family. It now asserts algorithm and value. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The blanket fragment rejection from the credential fix dropped a whole
ecosystem's download locations. Yarn appends the artifact's own sha1 to
every `resolved` URL ("...-1.4.0.tgz#71ee51fa..."), so scanning a Yarn
project produced 387 NOASSERTION and 1 real location — while the docs
this PR added promise Yarn gets real download locations. A fixed-length
hex digest is now recognized and stripped rather than treated as a
secret; that project is back to 379. Any other fragment shape is still
rejected, so the credential gate is unchanged for arbitrary values.
Repositories recovered from SPDX PackageSourceInfo skipped the ingest
gate. A source document asserting
"Source repository: https://user:secret@github.com/org/repo", or a
file:// path, was re-published verbatim in both formats — SPDX as
PackageSourceInfo, CycloneDX as a vcs reference. The value now goes
through normalizeRepositoryURL like every other ingested URL. Verified
load-bearing by reverting the call and confirming the test fails.
Two more from review:
- Revision precedence was backwards. For "?rev=main#abc123" the fragment
is the resolved commit and the query is what was requested, so the old
order recorded a moving branch instead of the commit that was locked.
This also contradicted uvSourceRevision, which prefers the fragment
when the same lockfile value is parsed for detection.
- A CycloneDX `publisher` is a free string the spec defines as a person
or an organization, and SPDX has no untyped originator. Defaulting to
"Organization:" asserted an entity type the source never made, which is
the exact class of invented claim this PR exists to avoid. The field is
now omitted on CycloneDX-to-SPDX and recorded as a conversion limit; it
still round-trips through CycloneDX, and a typed SPDX originator is
preserved. Supplier keeps its Organization type, since CycloneDX types
that field as an organizational entity.

…ions Five findings from review, all confirmed against the code before fixing. Unknown external-reference types could produce schema-invalid output. The CycloneDX library's version-downgrade pass rewrites unsupported types it recognizes, but its fallthrough returns true for anything else, so an arbitrary string from an ingested document was emitted verbatim against a closed enum. Preserved types are now checked against the encoder vocabulary and remapped to "other", which keeps the link and stays valid; per-version narrowing is still the library's job. BLAKE2b checksums were normalized to a canonical name neither encoder recognized, so they were silently discarded after the graph hop even on a same-format round trip. Both formats define BLAKE2b-256/384/512; the mappings were simply missing. This was self-inflicted: the previous commit added BLAKE2b to the normalizer without checking the encoders. Duplicate-PURL components lost their assertions. Several component IDs mapping to one PURL is a supported ingest shape, but only the first became a graph node and later duplicates were discarded whole, taking their supplier, description, distribution, digest, and CPE assertions with them. They are now merged with fill-gaps semantics and unioned set-valued fields. A person supplier was recast as an organization. CycloneDX has no person-valued supplier, so an SPDX "Person: Alice" became an organizational entity — the same invented-type problem as the publisher case, in the other direction. That conversion is now omitted; SPDX represents the type natively and still round-trips it. Detector-resolved commits were ignored. Bundler, pub, and the python detectors record a git dependency's resolved revision in Metadata["source_revision"] while leaving ResolvedURL as the bare remote, so those packages exported an unpinned, moving locator even though the commit was known. A safe revision is now folded into the locator. The two highest-risk fixes were verified load-bearing by reverting each and confirming its test fails.

…rtifact A credential could still reach output through the version-control path. That path is exempt from the query/fragment gate because normalizeVCS discards both and keeps a revision, but the revision itself was only checked with isSafeRevision, which permits letters, digits, and underscores — exactly the shape of an access token. An ingested "https://github.com/org/repo#ghp_abcd1234" was republished after the "@" in both formats. Confirmed by running the predicate over real token shapes before changing anything. Fragments must now be commit-shaped: bare hex, 4 to 64 characters. That is faithful to the format, since uv and cargo both write the resolved commit there, and it excludes token shapes on their underscores and non-hex letters. Query values keep the looser rule, because the key names them a revision and tags like "v1.2.3" are legitimate there. Two more from review: - A component asserting both a distribution and a vcs reference lost the repository. SPDX has one download-location field, the artifact takes it, and the source-info suppression was unconditional on VCSURL, so the repository was dropped even though PackageSourceInfo can hold it. Suppression now applies only when the VCS locator actually became the download location. - A primary component described in both metadata.component and the inventory kept only the inventory copy, so assertions placed on the metadata copy were discarded. They are now merged, inventory wins. The metadata-only primary component is deliberately still not promoted to a graph node: that is documented behavior (docs/SBOM.md), and adding it would demote the real graph roots on re-ingestion. Noted in code rather than changed silently. Verified the fragment guard is load-bearing by reverting it to isSafeRevision and confirming the test fails.

…maries
Malformed digests were copied verbatim from ingested documents. The
encoders filter on algorithm only, so {"alg":"SHA-256","content":
"not-a-hash"} survived the graph hop and was re-emitted: schema-invalid
in both formats, and a false integrity assertion about the package.
Ingested digests now go through the existing hex/SRI normalization and
are checked against the algorithm's expected length, dropping anything
that cannot be a digest.
This exposed unrealistic test data of my own: several fixtures used
"abc123" as a SHA-256, which is six hex characters rather than
sixty-four. The validator was right and the fixtures were wrong; they
now carry full-length values.
Comments on classified references were lost, and worse, replaced. A
distribution or vcs reference kept only its URL, so a producer's comment
disappeared on a CycloneDX round trip — and for a registry-shaped URL,
Bomly's fixed "Registry root" text was substituted, which can flatly
contradict an assertion such as "Exact authenticated download endpoint".
Comments now ride alongside each locator, and Bomly's explanatory text
is used only when the producer supplied none.
SPDX summary and description are no longer conflated. The decoder folded
PackageSummary into Description, which moves a summary into a
semantically different field and drops it outright when both are
present; SPDX 2.3 represents them distinctly. Summary is now carried
separately and restored on export, and is used in CycloneDX only as a
fallback, since that format has a single field.
Verified the digest validator is load-bearing by disabling its checks
and confirming the test fails. Real scans are unchanged: the detection
path does not route through this validation, and yarn/npm checksum
counts match the previous commit exactly.

… sets Four fidelity findings from review. CPE 2.2 locators were relabelled as 2.3. The previous commit taught the decoder to accept cpe22Type but the encoder still wrote every CPE as cpe23Type, so an ingested "cpe:/a:vendor:product:1.0" came back claiming a syntax it does not use. The two forms are self-describing, so the type is now derived from the locator rather than carried as extra state. Valid non-HTTP external references were dropped. CycloneDX external-reference URLs are IRI references, and rejecting every scheme outside http(s) and mailto discarded legitimate values such as a `bom` reference to "urn:uuid:...". urn, git, ftp, and ftps are now accepted; file:, data:, javascript:, and unknown schemes stay rejected, since these values are republished verbatim and denying the unknown is the safe default. External references were treated as a scalar in both merges. They are a set: each copy of a component may name a different link, so a fill-gaps copy dropped the second list whenever the first had any. This affected duplicate-PURL components at the graph level, where the whole list rides under one metadata key, and a primary component described in both metadata.component and the inventory at the model level. Both now union by type and URL. Both union fixes were verified load-bearing by reverting each to fill-gaps and confirming the tests fail. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Review flagged that TestBlake2bDigestsSurviveRoundTrip only counted checksums. The stated mechanism does not hold — both encoders skip an algorithm they cannot map, so a missing case already fails the count, which I confirmed by deleting the BLAKE2b cases and watching the test go red. But the suggestion closes a real gap in the other direction: a case mapped to the *wrong* constant keeps the count at one while relabelling the digest as a different family. Verified by pointing blake2b-256 at SHA256, which the old assertion accepted and the new one rejects. The test now asserts the exact emitted algorithm and value in both formats, and covers sha256 alongside the sha3 and blake2b families. Also corrects two stale statements: a failure message still naming the old "abc123" fixture value, and a docs sentence saying "three kinds" above a four-row table. The three kinds are right — an exact file, a source repository, a registry root — so the prose now names them and says plainly that a value fitting none of them is not published.

Two gaps, both mine, both the same shape: I added a guard on one path and left its siblings alone. The commit-shaped check only covered URL fragments. A revision also reaches the output verbatim from Metadata["source_revision"], which bundler, pub, and the python detectors populate from a lockfile, and from the rev/tag/branch query keys. Both still used isSafeRevision, whose own comment admitted it accepts access-token shapes. Those paths cannot simply require hex: a tag or branch is legitimate there and uses the same characters a token does. isSafeRevision now rejects known issuer prefixes instead — GitHub, GitLab, npm, PyPI, Slack, Stripe/OpenAI, AWS, Google, Hugging Face, DigitalOcean, Shopify. The doc comment states the limit plainly: this is a narrow check, a bespoke secret format would still pass, and the strong guarantee remains on the fragment path where bare hex is required. Tests cover both directions, including near-misses like "AKIRA" and "release_candidate". BLAKE2b was absent from digestHexSizes, so the ingest length check was skipped for exactly the algorithms the previous commit taught the encoders to emit: "ab" passed as a BLAKE2b-256 digest. Adding the encoder mappings without the paired size entries is the same omission as the BLAKE2b encoder gap two commits ago; the table now carries a note that every accepted algorithm needs an entry. Adding those sizes also exposed a wrong fixture of my own. The BLAKE2b test reused one 64-character value for every algorithm, and for BLAKE2b-384 that string is valid base64 decoding to exactly 48 bytes, so normalizeDigestValue rewrote it as an SRI digest and the assertion compared against a value the encoder never saw. Each case now uses its real hex width. All three fixes verified load-bearing by reverting each in turn. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Four findings, all cases where a guard was applied too bluntly. classifyAssertedDownloadLocation rejected every query, so an SPDX downloadLocation such as "https://repo.example/download?id=123" was re-exported as NOASSERTION. That example is the one my own doc comment used to describe the behavior, which the code did not actually produce — the comment stated the intent rather than the effect. The classifier now takes an explicit flag: a detector-supplied value still loses any query, because nothing asserts it is a download location and omitting is cheap, while a value the source document declared a download location keeps a benign query and is rejected only when a parameter name or value looks like a credential. git:// version-control references were dropped. isPublishableReferenceURL learned that transport last commit, but the narrower VCS path still permitted only HTTP(S), so a repository disappeared on a CycloneDX round trip. SPDX renders it "git+git://host/path", which its grammar allows. CPEs and digests were merged as scalars. External references were unioned last commit but their neighbours were not, so a component described in both metadata.component and the inventory lost whichever identifiers or hashes the second copy carried alone. Multiple distribution references overwrote one another. The neutral model has a single artifact slot, so listing mirrors meant only the last survived; the first classified value now takes the slot and the rest are preserved verbatim. Also re-attaches the classifyResolvedURL doc comment, which an earlier edit stranded above an unrelated const. Verified the query relaxation does not leak into the detector path, and mutation-checked it and the digest union. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Four findings, three of them the same failure repeated: a value is accepted on the way in and then quietly mangled or dropped on the way out. spdxSourceInfo stripped "git+" from a pinned locator, so "git+https://github.com/org/repo@deadbeef" became "https://github.com/org/repo@deadbeef" — an address where the revision is now part of the path, pointing at a repository that does not exist, and one that re-ingests cleanly as though it did. The version-control form is kept intact, and parseSPDXSourceInfo now recognizes it and restores it to VCSURL rather than reading it as a plain repository URL. CPE locators were preserved unchecked, so a document labelling "not-a-cpe" as cpe23Type had that republished as an SPDX security reference and as CycloneDX's cpe field: a false package-identity assertion, and non-conformant output. Both bindings are now validated — the 2.3 formatted string by component count and part, the 2.2 URI by component bound and part — with escaped colons treated as literals. Applied on both ingest paths, not just SPDX. BLAKE3 was accepted by parseSPDXChecksums and normalized, but neither encoder knew it, so an SPDX-to-SPDX round trip dropped it. Both formats define it; the mappings and the length entry were simply missing. That is the third algorithm to hit this, so the omission is systematic rather than incidental. Enrichment overwrote ingested CPEs and digests. Those are set-valued, so a matcher-supplied identifier or hash deleted the source document's own assertions, contradicting the documented ingest-wins ordering. Both are unioned now, matching what the two merge paths already do. The enrichment union and the CPE validation were mutation-checked. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Review surfaced five more instances of two bug classes I had been fixing one at a time. Rather than patch these individually again, this closes both classes and adds invariants so the next instance fails a test instead of a review. Set-valued fields treated as scalars. Audited every Component field against each merge path. Licenses and Vulnerabilities were still fill-gaps in mergeComponentAssertions, SupplierURL was a scalar where CycloneDX types an array, and multiple vcs references overwrote one another the way distribution mirrors used to. SupplierURL is now SupplierURLs, every set unions, and one test asserts licenses, supplier URLs, and external references all survive a duplicate-component merge. Algorithms accepted on ingest but unknown to an encoder. The audit found a fourth and fifth case beyond the three fixed one-by-one: SHA-224 is SPDX-only, and CycloneDX-only Streebog-256/512 were unmapped and unvalidated. Streebog is now wired; SHA-224 is a genuine format difference, so the invariant is that a validated algorithm reaches at least one encoder rather than both. Two table-driven tests now walk digestHexSizes and the encoder sets in each direction, so an algorithm added to one side without the other fails immediately. Also from review: - An ingested CycloneDX distribution reference is a source-declared download location, so it now uses the credential-aware classifier instead of the detector-oriented one, which rejects every query. A benign "?id=123" survives; "?token=" still does not. - SPDX NONE collapsed to NOASSERTION. Those are different assertions — not downloadable versus no claim made — so the marker is carried and re-emitted. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

A credential path I created by design decision. validatedVCSLocator deliberately returned the locator verbatim so the pinned revision would not be altered, and that choice bypassed revision validation entirely: in "git+https://host/org/repo@ghp_abcd1234" the suffix parses as part of the URL path, so neither the userinfo check nor isSafeRevision ever saw it. The suffix is now split off and validated; an unsafe one is dropped and the repository kept, matching normalizeVCS. CPE validation checked only the field count and the part, so "cpe:2.3:a:vendor with space:product:…" passed and was republished as a package-identity assertion. Every component is now checked as an avstring: printable ASCII, no whitespace, reserved punctuation escaped, no trailing lone backslash, and no empty part. Deliberately not over-strict: "*" and "?" stay legal unescaped, because partial values like "1.3.*" are common and rejecting them would drop real identity data — the same kind of harm as preserving a fabricated one. A corpus of thirteen NVD-style CPEs guards that direction. Note on method: my first mutation check of the CPE fix reported zero failures, which I nearly accepted. The revert had silently failed to match, so it measured nothing — and the test itself was also vacuous, because the same scripted edit had dropped the malformed cases while landing the well-formed ones. Both are now applied and verified: with the component loop removed the test fails on the whitespace case. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Twelve findings across both reviewers, nearly all in classes this PR has already fixed once. Grouping them by cause rather than by symptom. Credential detection. client_secret matched neither the parameter denylist nor the token-prefix check, so an asserted download carrying it was published. The list now covers the standard OAuth, session, and signature parameter names. Precedence. An SPDX package can declare downloadLocation NONE and still record a source repository; the recovered locator was winning, replacing an explicit "not downloadable" with a repository URL. NONE now outranks both locators. Gate consistency. Only the distribution reference used the credential-aware asserted-URL path, so "?version=1" on a documentation reference was dropped by the blanket query rejection. All source-declared references now share that gate, and ftp/ftps — already accepted for references — are allowed on the asserted-download path while detector-derived values stay HTTP-only. Set-valued fields. Vulnerabilities at the model level and licenses at the graph level were the last two still merging as scalars. Classified locators also crossed the graph as independent metadata keys, so a later locator's comment could attach to an earlier locator's URL; URL and comment now move as one unit. Algorithm vocabulary. ADLER32, MD2, MD4, and MD6 were accepted on ingest with no encoder mapping, the same shape as BLAKE2b and BLAKE3 before them. MD6 has no fixed width, so it is recorded as explicitly variable-length rather than given a wrong constant, and the coverage invariant now distinguishes "unmeasurable" from "forgotten". Fidelity. Supplier contacts and external-reference hashes are now preserved. I declined both earlier — contacts on privacy grounds — but that reasoning does not hold: the producer already published them, a format conversion is not a new disclosure, and the same principle already applied to supplier URLs. Two notes on method. Serializing contacts as maps and merging them with the string union would have silently dropped every one; the mutation check caught it. A second mutation check then reported no failures with the pattern confirmed applied, which showed the contact test used a single component and never reached the graph merge at all — that path now has its own duplicate-component test.

Two P1 credential paths, both introduced by my own earlier fixes, both the same root cause: "@" in a URL is ambiguous between userinfo and a revision suffix, and I resolved it inconsistently in two places. validatedVCSLocator split on "@" before parsing. For "git+https://ghp_secret@github.com" that reads the secret as the host and "github.com" as a revision, so url.Parse sees no userinfo, the revision passes isSafeRevision, and the original credential is rebuilt and republished. Splitting before parsing was exactly the wrong order. normalizeVCS validated only revisions recovered from a query or fragment. An already-rendered "@<revision>" sits in the URL path, where url.Parse leaves it alone, so a token survived on the two paths that reach normalizeVCS without going through validatedVCSLocator — a CycloneDX vcs reference and an SPDX downloadLocation. Both now use one splitVCSRevision helper that parses first, rejects userinfo, and only then separates a trailing revision. Each fix was mutation-checked by restoring the old ordering. Also: - swiftpm records its resolved commit under "revision", not "source_revision", so a reproducible pin exported as a moving repository. Both keys are read now. - Reference digests were carried on the distribution and default branches but not on extra vcs references. Three test defects, all mine, all the same shape — a test proving less than its name claims: - The reference-hash assertion matched the value as a substring, which would still pass if the algorithm were relabelled. It now decodes and asserts the algorithm too. - TestDuplicatePURLVulnerabilitiesAndLicensesAreUnioned set no vulnerabilities. Adding them would not have helped: ToGraph does not carry vulnerabilities, so they cannot survive that path whatever the merge does. The test is renamed to what it actually covers, and the vulnerability union is tested directly against mergeComponentAssertions along with every other set. - The trailing-backslash CPE case turned out to be genuinely covered already; I verified by mutation rather than assuming either way.

Ten findings across two reviews. Two P1 credential paths, and the security-boundary decision record had gone stale. Bare token query. "?ghp_abcd1234" parses as a nameless key with an empty value, and hasCredentialQuery checked names only against a fixed list while applying the shape check to values. The shape check now runs on names too. mailto targets. The opaque body of a mailto reference is inspected by none of the userinfo, query, or revision gates, so "mailto:ghp_abcd1234" was republished verbatim. A mailto reference now has to be a plausible address. Documentation. dev-docs/ARCHITECTURE.md still said every non-VCS query is rejected and that ingested URLs use the same gate as detector-derived values. Both stopped being true when the asserted-download path gained its credential-aware exception, and a stale security-boundary record is worse than none: it invites a future change to remove the exception or, worse, extend it to detector data. The record now states the three gates separately, says plainly that the distinction is the boundary, and records the parse-before-splitting rule that reintroduced a credential leak twice. Over-strict validation dropping real data: - CPE 2.2 URI bindings were checked with the 2.3 formatted-string rules, which reject empty components and the packed edition's tildes. A genuine identifier such as "cpe:/a:hp:insight_diagnostics:7.4.0.1570::~~online~win2003~x64~" was discarded. The URI binding now has its own grammar. - svn+, hg+, and bzr+ version-control references were rejected because the prefix trim assumed Git. - A CycloneDX supplier identifying itself only by URL or contact was dropped entirely: the name is optional on an organizational entity, and the whole block was gated on it. Under-strict validation preserving bad data: - An escaped rune in a CPE component skipped the printable-ASCII check, so a backslash followed by a control byte passed. Preservation gaps: - Integrity assertions on classified distribution and vcs references were lost, because those land in scalar locator fields rather than in ExternalRefs where digests were carried. - unionExternalRefs treated a matching type and URL as a complete duplicate, discarding the later record's digests and comment. - Reference URLs were stored untrimmed although the gate validated a trimmed copy. The three security fixes were mutation-checked with the mutation asserted to have applied. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

The worst of this batch is a regression against the PR's own core guarantee, reached through Bomly's own output. Bomly exports a registry-backed dependency as a CycloneDX distribution reference marked "Registry root; not the exact artifact location". Re-ingesting that document promoted every registry-shaped URL to an artifact, so an SPDX export published https://rubygems.org/ as the exact downloadLocation for 130 packages — precisely the failure the classifier exists to prevent. CycloneDX defines `distribution` as where the artifact can be obtained, so promotion is faithful to the spec and the marked case is the exception. The marker is now a shared constant that ingest believes over the URL's path shape. Verified end to end: the ruby round trip returns 136 NOASSERTION with the marker preserved, while npm keeps its 136 real download locations. Second P1: a URN's payload is segmented, so "urn:uuid:ghp_abcd1234" has opaque "uuid:ghp_abcd1234" and a prefix check on the whole string never saw the token. Each segment is inspected now. Merges that could fabricate an assertion: - Locator URL, comment, and digests were merged as independent fields, so a surviving URL could take another URL's comment and both URLs' hashes — a false integrity assertion. Each locator now merges as one record, and the losing locator is preserved as an external reference rather than dropped. - The three locator digest sets ride under one metadata key, and the whole map was kept whenever any slot existed, so a duplicate's hashes were lost for slots the first component never filled. Merged per slot. Also: URI-bound CPEs now require well-formed percent escapes; the SPDX source-info recovery branch recognizes every VCS tool prefix rather than only git+; an ingested VCS assertion outranks the Scorecard repository, matching the documented precedence; and a host-only Scorecard URL is rejected, since it names no repository. The registry-root marker and the atomic locator merge were mutation-checked. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

When an SPDX description or summary is the ordinary text None or NoAssertion, this case-folding treats it as a reserved marker and silently deletes it during re-export. SPDX sentinel values are the exact uppercase literals NONE and NOASSERTION; compare those spellings directly so legitimate mixed-case free text in the newly preserved fields survives.

When a marked registry-root distribution reference carries hashes, decoding stores them in RegistryDigests and the graph metadata preserves them, but this encoder branch recreates only the URL and comment. Fresh evidence after the classified-reference hash fix is that the registry branch still never assigns Hashes, so even a single-component CycloneDX-to-CycloneDX round trip silently removes the reference's integrity assertion.

P1: a token in the URL path was never inspected. looksLikeCredential is applied to query names and values, revisions, mail addresses, and URN segments, but "https://repo.example/download/ghp_abcd1234/pkg.tgz" has no userinfo, no query, and no fragment, so every gate passed it through verbatim. Path segments are now decoded and checked at all four entry points. The rest of this batch is a layer sweep rather than another round of instance fixes. Three findings were the graph-level twins of merge defects I fixed at the model level last round: a conflicting locator discarded instead of preserved as a mirror, a matching locator's digests dropped, and a duplicate external reference skipped rather than merged. Fixing each report where it landed is what let the same bug persist one layer down, so the graph helpers now mirror the model helpers directly. Two more of the same shape: - The shared classifier stripped only "git+", so an SPDX downloadLocation of "svn+https://…" failed the transport gate and re-exported as NOASSERTION. It uses the shared VCS-prefix parser now, like the two callers that already did. - The registry-root encoder branch recreated its reference without hashes, though the artifact and vcs branches had been fixed. Also: SPDX sentinel comparison is case-sensitive again. The literals are NONE and NOASSERTION, so case-folding silently deleted ordinary free text such as a description of "None" from the newly preserved fields. The credential-path gate, the graph mirror preservation, and the registry-root hashes were each mutation-checked. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

When an untrusted SPDX PackageSourceInfo contains Source repository: https://github.com/ghp_abcd1234/repo, parseSPDXSourceInfo reaches this absolute-URL branch, which checks userinfo, query, and fragment but never calls hasCredentialPath; the token is therefore stored as Repository and republished in both SPDX and CycloneDX output. Fresh evidence after the earlier path-segment thread is that the current normalizeRepositoryURL branch remains an entry point that accepts the same credential-shaped segment, so apply the path gate before returning the URL.

When an SPDX downloadLocation is svn+https://svn.example.org/project (likewise hg+ or bzr+), classifyURL recognizes and strips the tool prefix but normalizeVCS unconditionally rebuilds the locator with git+. The round trip therefore changes the asserted VCS rather than merely normalizing it; the added test misses this because it checks only that example.org/project remains.

The round-trip test asserted only that the host and path survived, which the rewrite preserves; it asserts the whole locator now, and a new test pins the tool for all four prefixes.

When an SPDX package declares downloadLocation: "NONE" and carries Source repository: git+https://github.com/org/repo@deadbeef, decoding correctly records both NoDownloadLocation and VCSURL, but this condition suppresses the source-info field merely because no artifact exists. spdxDownloadLocation then emits NONE, so the valid repository assertion disappears entirely; the added TestNoneDownloadLocationOutranksRecoveredRepository checks only that NONE survives and misses this loss.

Fixed, and again the test was the weak part. Suppression now applies only when the VCS locator is the value spdxDownloadLocation actually emits — with NONE asserted, the repository is not duplicated there, so dropping source info lost it outright. My test checked only that NONE survived; it now also asserts the repository assertion beside it. Mutation-checked.

P1: normalizeRepositoryURL was a fifth entry point into the path gate and did not use it. An SPDX "Source repository: https://github.com/ghp_abcd1234/repo" checked userinfo, query, and fragment but never the path, so the token was stored as Repository and republished in both formats. I added the gate at four call sites last commit and missed this one. normalizeVCS rebuilt every locator with "git+", so an asserted svn+/hg+/bzr+ download location came back as Git. That changes which version-control system the document asserts rather than normalizing it. The detected tool is carried through now. Two more, both caught only because the reviewer read the tests rather than trusting them: - validatedVCSLocator accepted "git+https://github.com", which names no repository. The other normalization paths already required a path. - A package declaring downloadLocation NONE alongside a source repository lost the repository entirely: NONE is emitted as the download location, so source info was suppressed for a duplicate that was never written. Suppression now applies only when the VCS locator is the value actually emitted. Both of my earlier tests were too weak to catch their own bugs. The non-Git round trip asserted only that the host and path survived, which "git+" rewriting preserves; it now asserts the whole locator. The NONE test asserted only that NONE survived; the repository assertion it was silently dropping is now covered. All four fixes were mutation-checked, with the mutation asserted to have applied.

When untrusted SPDX source info contains Source repository: github.com/ghp_abcd1234/repo, this scheme-less branch parses the generated HTTPS URL but never applies hasCredentialPath, so the token survives in Repository and is republished in SPDX and CycloneDX.

Fixed. normalizeRepositoryURL has two branches and I only gated the absolute-URL one last round; the scheme-less sibling in the same function kept the token. Mutation-checking this also showed the prefix check I first added beside it was dead — hasCredentialPath already covers the case, segment-wise and more correctly — so I removed it rather than leave decoration that looks like a safeguard.

When an ingested CycloneDX supplier contact uses a syntactically valid credential-shaped address such as ghp_abcd1234@example.com, this copies it verbatim and the encoder publishes it again. Fresh evidence beyond the fixed mailto: path is that direct organizational-contact emails bypass isEmailAddress and therefore its credential check entirely; validate or drop the email before storing the contact.

Fixed. Organizational contacts reach the output without passing through the mailto gate, so a credential-shaped address was republished verbatim. Contact emails are now validated with the same isEmailAddress check; an unusable address is dropped and the contact kept if a name or phone remains.

When a supplier URL has surrounding whitespace, isPublishableReferenceURL validates a trimmed local copy but this appends the original u, so re-export emits the padded value and can produce a CycloneDX document that fails the IRI-reference format.

When an untrusted CycloneDX reference contains a malformed opaque URN such as urn:uuid:%ZZ or urn:foo bar, url.Parse accepts the opaque text and this branch returns true after checking only emptiness, query, fragment, and credential prefixes. The original raw value is then re-emitted and can make the generated CycloneDX document fail its IRI-reference constraint; fresh evidence beyond the credential-segment fix is that the URN payload still receives no character or percent-escape validation.

This commit introduces a hand-written parser for CPE values read from untrusted SPDX and CycloneDX documents, including escape handling, URI-bound components, percent encodings, and two separate grammars, but the repository contains no Fuzz* target for isValidCPE and scripts/run-fuzz.sh registers only the new locator fuzzers.

Fixed, and this is the one I should have caught myself — CLAUDE.md requires a fuzz target for exactly this kind of parser and I registered targets only for the locator helpers. Added FuzzIsValidCPE with valid, malformed, and truncated seeds, bounded by testkit.MaxFuzzInputSize, registered in scripts/run-fuzz.sh. It found a real bug within seconds: isValidCPE trims internally but the CycloneDX path stored the untrimmed original, so a padded CPE passed validation and was re-emitted with its whitespace. Fixed, and 2.4M executions are now clean.
🤖 Addressed by Claude Code
The most important item here is procedural: this change introduced a hand-written CPE parser over untrusted SPDX and CycloneDX input — two grammars, backslash escapes, percent encoding, a packed edition — and registered no fuzz target for it. CLAUDE.md requires one for exactly this, and I registered targets only for the locator helpers. Added FuzzIsValidCPE with valid, malformed, and truncated seeds, bounded by testkit.MaxFuzzInputSize, registered in scripts/run-fuzz.sh. It found a real bug within seconds. isValidCPE trims internally, but the CycloneDX path stored the untrusted original, so a padded CPE passed validation and was re-emitted with its whitespace — the same gate-trims-but-caller-stores-raw defect already fixed for external references and supplier URLs. All three sites are consistent now, and a test covers the class rather than the instance. Three credential paths: - normalizeRepositoryURL has two branches and only the absolute-URL one had the path gate. A scheme-less "github.com/ghp_abcd1234/repo" from SPDX source info kept the token. Fixing this also showed the prefix check I added alongside it was dead — hasCredentialPath already covers the case, segment-wise and more correctly — so it is removed rather than left as decoration. - Supplier contact emails reached the output without the validation a mailto reference gets, so "ghp_abcd1234@example.com" was republished. An unusable address is dropped and the contact kept. - URN payloads were checked for credential prefixes but not syntax, so "urn:foo bar" or a bad percent escape could break the document's IRI-reference constraint. Every fix was mutation-checked. One mutation reported zero failures, which is what surfaced the dead check above. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

isPublishableReferenceURL is a new hand-written parser for untrusted SBOM URLs, including HTTP queries and paths, mail addresses, URNs, percent escapes, and credential detection, but no fuzz target directly exercises it; FuzzClassifyResolvedURL covers the detector-only classifier, while the generic codec seeds contain no external references.

Added FuzzIsPublishableReferenceURL and registered it in scripts/run-fuzz.sh. You were right that this parser needed one: it immediately found the inverted-precedence bug above, plus a series of credential positions the segment-splitting check was missing. That drove replacing the splitting entirely — containsCredential now scans a whole component for an issuer prefix at a token boundary, so there is no delimiter set left to get wrong, and the fuzz invariant scans the whole value independently of how the implementation splits anything. 10.4M executions clean.

When duplicate-PURL components have different URLs in the same locator slot and only the incoming URL carries hashes, mergeLocatorPairs correctly preserves the incoming URL as an external reference, but this subsequent whole-map merge fills the primary slot's missing digest list from that incoming URL. applyIngestedMetadata then attaches those hashes to the surviving first URL as well, fabricating an integrity assertion. Fresh evidence after the prior conflicting-locator fix is that the generic digest-map merge still runs after the atomic conflict handling; conflicting slots must be excluded here.

When a formatted CPE contains an escaped alphanumeric such as cpe:2.3:a:ven\qdor:product:1.0:*:*:*:*:*:*:*, this branch accepts it merely because q is printable, although the formatted-string binding permits backslash quoting only for its escapable punctuation.

When a resolved or asserted URL places a recognizable credential in a hostname label, such as https://ghp_abcd1234.repo.example/a.tgz, parsed.User is nil and its path and query are clean, so this gate accepts and republishes the token verbatim. Unlike the already-covered userinfo, path, query, fragment, and revision positions, none of the detector, VCS, repository, or external-reference entry points inspect parsed.Hostname(); apply the credential-shape check to decoded hostname labels in the shared URL validation.

Fixed, and it prompted a rewrite rather than a patch. Hostnames were never inspected, so a token in a host label passed every gate. Adding the check by blanket string replace then produced !a || b where !(a || b) was meant, inverting the reference gate so it accepted credential hostnames — the new fuzz target caught that on its first run.

When a CycloneDX component lists a marked registry-root distribution reference before an exact archive reference, setting RegistryURL here prevents every later distribution from being classified. The archive is retained only as a generic ExternalRef, which spdxDownloadLocation never examines, so CycloneDX-to-SPDX conversion emits NOASSERTION even though the source supplied an exact download location. Classify all distribution references and let an artifact displace the weaker registry slot regardless of array order, preserving the registry root as an extra reference.

The credential check was segment-based: split a URL component on a set of delimiters, then prefix-match each segment. Every delimiter missing from that set was a silent gap, and the new reference-URL fuzz target found them one after another — a token after "&", then after ".", then after ":" — each fix revealing the next. That is the same instance-by-instance pattern this review has hit repeatedly, so the splitting is gone. containsCredential scans a whole component for an issuer prefix at a token boundary, which has no delimiter set to get wrong and is the same check wherever it is applied. A prefix must also be followed by at least eight token characters: a bare "ghp_" is a prefix, not a secret, and treating it as one rejected ordinary URLs. The boundary requirement is what keeps it quiet on real text — "task-runner" no longer trips the "sk-" prefix. Two P1 gaps closed with it: - Hostnames were never inspected. "https://ghp_abcd1234.repo.example/…" has nil userinfo, a clean path, and no query, so every gate passed it. - isPublishableReferenceURL had no fuzz target, though it parses untrusted URLs across several schemes, mail addresses, URN payloads, and percent escapes. AGENTS.md requires one for every such parser; the CPE validator needed the same and got it last commit. Applying the host check by blanket string replacement produced "!a || b" where "!(a || b)" was meant, inverting the reference gate so it accepted credential hostnames. The fuzz target caught that on its first run, which is the argument for the target existing. Also from review: escaped CPE runes are validated against the formatted-string escape vocabulary rather than all printable ASCII; the conflicting-locator digest merge no longer attaches the incoming URL's hashes to the surviving URL; and an exact artifact now wins the download slot over a registry root regardless of array order. Test fixtures used toy tokens like "glpat-Abc123" whose bodies are shorter than any real credential, which is what let the body-length rule look wrong at first. They carry realistic lengths now.

When an ingested component asserts a SHA-256 value and enrichment supplies a different SHA-256 value for the same PURL, this full-record union retains both hashes.

Not changed, and I want to be explicit that this is a judgement call rather than an oversight.
The finding is correct: git+ssh://git@github.com/org/repo is a standard locator and it is currently dropped, both by the transport allowlist and by the blanket userinfo rejection. Preserving it means carving an exception into the userinfo rule — accept a username, reject a password, reject a credential-shaped username.
That rule has been the source of two P1 credential leaks in this PR already: once from splitting on @ before parsing, and once from an @<revision> suffix re-parsing as userinfo. Adding a conditional accept path to the single most security-sensitive predicate in the file, at this point in the review, is the kind of change that wants its own diff and its own adversarial pass — not to be folded into a batch of seven other fixes.
Noted for the follow-up issue alongside the rest of the round-trip fidelity work.

Dependency.Metadata is not private to the SBOM detector. Any detector, including an external plugin, can set bomly.sbom.* keys, and applyIngestedMetadata trusted them: a plugin returning "bomly.sbom.artifact_url: file:///home/runner/secret" overwrote a locator that had just passed the classifier and reached the published document. Restoring is an ingest path, so restored values now clear the assertion-level gate, the same one they passed on the way in. My own fuzz helper had drifted from the classifier. assertPublishableLocator still accepted only git+http(s), while the classifier deliberately keeps svn+, hg+, and bzr+ — so `make fuzz` and the scheduled workflow would have failed on correct behavior. It now accepts every prefix in vcsToolPrefixes. Conflicting integrity assertions are resolved rather than accumulated. An ingested SHA-256 and an enrichment SHA-256 with different values were both emitted, leaving two incompatible claims about one component; digests merge by algorithm now, so ingest wins a conflict and enrichment adds only algorithms the document lacked. The test asserted both values survived, which is the contradiction rather than the fix, so it now pins ingest-wins and additive-on-new-algorithm. Also: - The checksum-fragment exception exists for Yarn's detector-derived values; applying it to source-declared references silently changed another producer's asserted target. It is detector-only now. - The NONE marker merged independently of locator state, so duplicate PURLs could emit NONE in SPDX while CycloneDX still emitted the artifact. It follows the locator's first-component-wins policy. - URI-bound CPEs rejected raw backslashes and the other characters the binding requires to be percent-encoded. - Supplier contact emails are stored trimmed, as supplier URLs already were. Not changed: ssh VCS locators. Accepting "git+ssh://git@host/repo" means carving an exception into the userinfo rule, which has been the source of two P1 credential leaks in this PR.

When duplicate-PURL components arrive in the opposite order from the added regression test—first an SPDX NONE assertion and then an exact artifact URL—this fill-empty branch adopts the later locator while leaving metadataKeyNoDownload set.

When a built-in or external detector supplies a malformed value in sdk.Dependency.CPEs, this newly added projection copies it without the isValidCPE gate used for ingested SPDX and CycloneDX data. The encoders then emit the first value as CycloneDX's cpe and every value as an SPDX security reference, allowing a detector result to produce a non-conformant document or false package identity; filter graph CPEs through the same validator before storing them.

Closing in favor of #395, which carries only the export side of this work. This PR grew far past what #380 asked for. It ended up containing two distinct changes: emitting package-origin data during export (small, stable, well-verified), and preserving third-party assertions through SBOM ingest and re-export (large, and demonstrably not settled — the final review rounds were still finding real gaps in that half, including a trust-boundary issue on plugin-writable metadata keys). Split outcome:
Nothing here is lost — the branch remains for reference, and the ingest work restarts from a scoped design rather than accreting under review. 🤖 Generated with Claude Code |

Addresses #380.
The issue's premise does not hold
#380 asked for per-component
supplieranddescriptionsourced from deps.dev during--enrich. Probing the live deps.dev API across npm, PyPI, Maven, NuGet, Cargo, and Go showsGetVersionasserts neither field — it carries onlylinks[](SOURCE_REPO,HOMEPAGE,ISSUE_TRACKER,DOCUMENTATION,ORIGIN) andregistries[]. A description exists only on the separate project endpoint, where it is the source repository's description, so every package in a monorepo would get the same text.Real per-package supplier and description live only in registry-native metadata (npm
author/maintainers, PyPIauthor, Maven POM<organization>, NuGet nuspec<authors>). Reaching those needs new allowed network hosts — a CLAUDE.md non-negotiable — and likely a newbomly-plugin-*repo.Supplier and description are therefore deferred. This PR ships the subset that needs no new source: metadata Bomly already collects and then dropped at the export boundary, plus assertions a third party made in an SBOM Bomly ingests. Nothing is invented.
This does not close the CRA supplier error. A follow-up issue for registry-native supplier/description should be filed, and #380 re-scoped rather than closed by this PR.
What changed
Package origin.
ResolvedURLis not a URL. npm/pnpm/yarn/bun record the exact tarball; Bundler records theGEM remote:registry root; Cargo records aregistry+/sparse+/git+prefixed index or repo; swiftpm records a repository; and uv, pipenv, pub, and npm link entries can all record a local filesystem path. Newinternal/sbom/locator.goclassifies each value before it can reach a document:downloadLocationdistributiondownloadLocation(git+form)vcsNOASSERTIONdistribution, marked as a rootNOASSERTIONTwo rules are load-bearing:
Source, because uv'spath/editablevalues arrive under non-filesources.https://rubygems.org/is schema-valid and both validators accept it, so the failure would be silent and plausible: every consumer would read it as the artifact's origin.Scorecard repository → CycloneDX
vcs, SPDXPackageSourceInfo(notPackageHomePage, which asserts a different thing).Round-trip preservation. Ingest is not decode-then-encode:
ToGraphconverts to ansdk.Graphand export rebuilds a fresh document, so supplier/description/external references were lost by a format conversion even though both decoders could see them. They now rideDependency.Metadataunderbomly.sbom.*keys, following theSetDetectionLicensesprecedent — no SDK change.ToGraphdeliberately does not setDependency.Source, which feedsRegistryMatchEligibleand would quietly breakscan --sbom --enrich.Precedence: detection classifies, ingest corrects, enrichment fills gaps.

The two new fuzz targets found four real bugs while being written, all of which would have produced malformed or unsafe output:
