Conversation
Detectors know what their lockfile fields mean: npm's `resolved` is a tarball, cargo's `git+...#sha` is a pinned repository, uv's `editable` is a local path. Recovering that from the URL string alone, downstream, cannot be done reliably — every shape has an ecosystem-specific counterexample. Add the carrier and its single invariant so each detector can assert where a package came from, and so SBOM export can publish it without re-deciding anything: - `bomly.origin.*` metadata keys hold an exact artifact URL, or a repository URL plus the resolved revision, or nothing. - `NormalizeOriginURL` is the one rule every published origin satisfies: absolute http(s), host present, no userinfo, re-serialized from the parse. Local paths, file://, ssh, scp-style remotes, and credentialed URLs cannot reach an SBOM. It runs on the way in and again on the way out, so a plugin-supplied graph is held to the same rule as a built-in detector. - Command output filters the shared key prefix: origin is a transport between detection and export, and the SBOM is where users read it. No detector emits yet, and nothing reads the keys yet. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Each detector now says where a package came from, using the field its own lockfile records it in: - npm, pnpm, yarn, and bun assert the registry tarball they fetched. Yarn Classic's checksum fragment is dropped, pnpm v9 entries carrying only an integrity hash assert nothing, and npm workspace members keep asserting nothing because their "resolved" is a local directory. - uv, poetry, pipenv, and pip read their explicit source types: a repository plus the commit that was locked, a direct archive URL, or nothing for index installs, editable projects, and local paths. - cargo unwraps "git+", taking the resolved commit from the URL fragment and falling back to the requested rev/tag/branch; index sources assert nothing. - Bundler emits for GIT sections, SwiftPM for source-control pins, and pub for git packages -- not for gem servers, registry pins, or local checkouts. Registry and index roots are deliberately absent everywhere: they say where an ecosystem fetches from, not where this package came from, and a private server URL with a path is indistinguishable from a repository once it is out of context. ResolvedURL keeps its existing value at every site, so repository resolution in the scorecard matcher is unchanged. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…ry locations SPDX packages now carry a real download location instead of a constant NOASSERTION: the artifact URL a detector resolved, or the repository in SPDX 2.3's version-control form, "git+<url>@<revision>". CycloneDX components gain a distribution or vcs external reference, the latter as a plain URL since the format has no revision slot on references. Export decides nothing. It reads the origin detection recorded, re-validates it against the same invariant that admitted it, and projects the result; a package whose detector asserted nothing keeps NOASSERTION rather than a guess. The re-validation is what makes this safe for graphs Bomly did not build itself, such as a plugin's. The scorecard matcher's canonical repository fills the gap for packages whose lockfile named no repository, and never overrides one a detector asserted. Verified against the official SPDX validator (spdxlib.ValidateDocument) and the CycloneDX 1.4/1.5/1.6 JSON schemas, on real npm and cargo scans. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
docs/SBOM.md gains a "Where a package came from" section: what each detector reports, how the two shapes map onto each format, and the four kinds of value that are never published -- registry roots, local paths, non-web remotes, and credentialed URLs -- with the reasoning for each. dev-docs records the decision and, more usefully, why the export-side classifier it replaces could not work: ResolvedURL is not one kind of value, so recovering its meaning downstream is guesswork with a per-ecosystem counterexample for every rule. The new smoke case scans a real npm repository and asserts on the exported bytes rather than a golden -- SBOM documents carry a namespace, serial number, timestamp, and tool version that change every run. It checks that real lockfiles produce real download locations, and that nothing about the scanning machine reaches the output. Both slice matrices gain the test and the node toolchain it needs, so it cannot silently skip. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

There was a problem hiding this comment.
When a Bomly-generated SPDX document is ingested and exported again, the resolved commit does not survive: spdx23Codec.decodeJSON ignores PackageDownloadLocation, and ToGraph does not reconstruct the bomly.origin.* metadata, so the subsequent export emits NOASSERTION. Either preserve the locator during ingest or document that package origin, including its revision, is lost on round trip.

For supported package-lock.json v1 inputs, this origin hook is never reached because depGraphFromNPMLockfile takes the len(lockfile.Packages) == 0 fallback and returns early. That fallback also deserializes dependencies through node.NPMListNode, which has no resolved field, even though v1 lockfiles record the same tarball URLs, so these scans still export NOASSERTION for every package while v2/v3 scans publish origins. Preserve resolved through the v1 path and call the origin setter there as well.

There was a problem hiding this comment.
When a caller updates an origin on the same dependency, the setters only add or overwrite the keys they receive. For example, two SetOriginVCS calls where the second has no valid revision leave the first revision attached to the second repository, while switching from an artifact to VCS leaves both keys and OriginFrom silently keeps the stale artifact. This violates the advertised at-most-one-location invariant and can export a fabricated repository/revision pair, so clear the prior artifact, repository, and revision keys before storing a replacement.

Inline comments:
In `@dev-docs/ARCHITECTURE.md`:
- Around line 609-610: Update normalizeGraphPackageIdentity and the SDK
graph-merging/deduplication path so nodes sharing an ID do not silently discard
conflicting bomly.origin.* metadata; preserve each origin per occurrence or
apply an explicit deterministic conflict policy. Add a test covering duplicate
nodes with one ID and different origins, verifying the selected behavior.
In `@docs/SBOM.md`:
- Around line 150-153: Clarify the validation statement in the
published-location documentation so the underlying detector-origin URL must be
an absolute HTTP(S) URL with a host and no embedded credentials, while SPDX
mapping may compose that validated URL into its git+URL@revision locator form.
Keep the existing re-serialization and export-time validation requirements.
- Around line 111-120: Update the detector documentation table to show that VCS
origins may be recorded as SPDX git+<url> or git+<url>@<revision>, and clarify
that a valid revision is represented only in SPDX while CycloneDX contains the
repository URL without the revision.
In `@internal/detectors/node/npm/npm_lockfile_parser.go`:
- Around line 251-254: Update the v1 npm dependency construction in
node.DepGraphFromNPMNode to carry each dependency’s resolved value into its
generated dependency metadata, then ensure the v1 parsing path calls
detectors.SetOriginArtifact with that value. Add a test verifying the resolved
URL is preserved as the dependency’s origin artifact.
In `@internal/detectors/origin.go`:
- Around line 118-136: Update SetOriginVCS and the corresponding
SetOriginArtifact setter so accepted origins remove conflicting origin metadata
before storing the new value; when SetOriginVCS receives an invalid revision,
also clear any existing MetadataKeyOriginVCSRevision. Preserve nil and
invalid-URL no-op behavior while ensuring setters never leave both origin forms
or stale revision data.
- Around line 90-98: Update the URL validation branch around parsed.RawQuery and
parsed.ForceQuery so non-VCS artifact URLs also require a non-root parsed.Path.
Reject registry-root URLs such as https://registry.example/ while preserving the
existing VCS query normalization and rejection behavior.
In `@internal/sbom/model.go`:
- Around line 139-145: Update the field documentation for ArtifactURL and VCSURL
to scope the “at most one” invariant to detector-asserted origins, and
explicitly note that registry enrichment may add a repository URL even when an
artifact URL is already present. Keep the existing VCSRevision relationship and
URL-format descriptions accurate.

| Two consequences worth stating. Origin keys are filtered out of `scan`/`diff`/`explain` payloads by prefix in `output.cloneRefMetadata` — they are transport between two pipeline stages, and the SBOM is where users read them; the filter returns nil for an emptied map so `omitempty` still fires. And consolidation's first-wins node dedup can drop the origin of a duplicate occurrence, which matches the existing behavior of `ResolvedURL` itself. | ||

github.com/bomly-dev/bomly-sdk GraphContainer ConsolidatedGraph AddNode Dependency ID metadata ResolvedURL
💡 Result:
The bomly-sdk provides a graph-based representation of software dependencies used by the Bomly CLI [1][2]. Based on the codebase, here is the synthesis of the components you mentioned: GraphContainer and ConsolidatedGraph In the Bomly architecture, detection-time dependency graphs are initially resolved for subprojects (e.g., individual directories containing manifest files) and then consolidated into a single, unified structure [3][2][4]. While the SDK provides the core Graph type (sdk.Graph) for representing dependency topology [1], the result of the scan pipeline is often referred to as a ConsolidatedGraph [1]. This consolidation step deduplicates package sets and merges per-subproject graphs into a single graph used for subsequent auditing and matching [3][2]. AddNode and Dependency The sdk.Graph object is node-centric, where each node is represented by an *sdk.Dependency [1]. - AddNode(dep *sdk.Dependency): This method is used to add a dependency to the graph [1]. It returns an error (typically ErrNodeAlreadyExist) if a collision occurs based on the node's stable ID [1]. - Dependency: This struct represents a node in the detection-time graph [3][2]. It carries specific metadata such as scope, location of discovery, and edges to other dependencies [3]. It points to a package by its PURL (Package URL) but does not itself contain enriched data like vulnerabilities or licenses [3]. ID, Metadata, and ResolvedURL - ID: Nodes in the graph are identified by a stable ID [1]. This ID is used for lookups (g.Node(id)) and to define the topology [1]. - Metadata: Dependency metadata is handled primarily through fields within the sdk.Dependency struct and associated helpers [1][5]. This includes coordinates (Name, Version, PURL), scopes, and detection-time facts [3][5]. Additional enrichment (e.g., license or vulnerability data) is typically held in the PackageRegistry, which is keyed by PURL, rather than stored directly within the graph nodes [1][5]. - ResolvedURL: While there is no single "ResolvedURL" field explicitly detailed as a primary SDK type in the documentation snippets, Bomly uses PURLs (Package URLs) as the canonical, stable identifier for matching artifacts within the PackageRegistry [1][3][5]. For detailed implementation, the canonical API is found in sdk/graph.go, and models are defined in dev-docs/MODELS.md within the bomly-cli repository [1][2].

Preserve conflicting origin metadata during node deduplication.
normalizeGraphPackageIdentity and SDK graph merging deduplicate by node ID, which excludes Dependency.Metadata and ResolvedURL. The merge keeps the first node and merges only relationships and locations, so duplicate nodes can lose bomly.origin.* metadata. Define conflict handling or preserve origins per occurrence, and add a test for different origins with one node ID.

Clarify the scope of the HTTP(S) validation rule.
The text says every published location is an absolute HTTP(S) URL. This conflicts with the SPDX mapping on Line 116, which emits git+<url>@<revision>. State that the underlying detector-origin URL must satisfy the HTTP(S) rule, then explain that SPDX composes the validated URL into its locator form.

Preserve v1 npm resolved URLs as origin artifacts.
The v1 path loses resolved values because node.NPMListNode does not define that field, and node.DepGraphFromNPMNode creates dependencies without origin metadata.

Keep setter-produced origins mutually exclusive.
Calling SetOriginVCS and then SetOriginArtifact leaves both origin forms in dep.Metadata. Calling SetOriginVCS again with an invalid revision also leaves a prior revision. This contradicts the Origin invariant and the statement that setters never produce both forms. Clear conflicting origin keys before storing the accepted value.

The documented invariant no longer holds after registry enrichment.
The comment states that at most one of ArtifactURL and VCSURL is set. enrichComponentFromRegistry in internal/sbom/transform.go (Lines 314-319) sets VCSURL from Scorecard data whenever VCSURL is empty, including when ArtifactURL is already populated. Both fields can therefore be set on the same component. Restate the invariant so it describes detector-asserted origins only, and state that enrichment may add a repository alongside an artifact URL.

Closes part of #380 (the origin half; supplier/description remain out of scope — see below).
Replaces #395, which derived package origin at the SBOM export layer by classifying
Dependency.ResolvedURL. That approach did not converge over ~20 review rounds, and the reason generalizes:ResolvedURLis not one kind of value. npm writes a registry tarball there, but also a local directory for link entries; uv writes a repository, an archive, an index root, or an editable path; Bundler writes a gem server, a repository, or a directory. Recovering the meaning downstream is guesswork, and every rule had an ecosystem-specific counterexample — an archive-extension check misclassifies repositories ending in.zip, a URL fragment is a resolved commit in uv but a content checksum in Yarn Classic, and an opaque token is not distinguishable from a content hash at all.This PR asserts origin where the meaning is known.
What changed
Each detector reports its own origin from the field its lockfile records it in — an exact artifact URL, a repository plus resolved revision, or nothing. Twelve resolvers across npm/pnpm/yarn/bun, uv/poetry/pipenv/pip, cargo, Bundler, SwiftPM, and pub.
ResolvedURLkeeps its existing value everywhere, so scorecard repository resolution is untouched.Export projects it and decides nothing. SPDX packages get a real
downloadLocation(the artifact, orgit+<url>@<revision>) instead of a constantNOASSERTION; CycloneDX components get adistributionorvcsexternal reference.One rule replaces the classifier —
NormalizeOriginURL: absolute http(s), host present, no userinfo, re-serialized from the parse. Local paths,file:, ssh remotes, and credentialed URLs fail the scheme, host, or userinfo check rather than a bespoke heuristic. No archive-extension table, no credential-prefix list, no secret-shape detection. It runs when a detector records a value and again at export, so plugin-supplied graphs are held to the same rule.Registry and index roots are never published.
https://rubygems.org/,https://pub.dev, and the crates.io index describe an ecosystem's fetch configuration, not a package's provenance — and once out of context, a private server URL with a path is indistinguishable from a repository.Deliberate behavior notes for review
vcsrefs are plain URLs. The format has no revision slot on external references, so a resolved commit survives an SPDX round trip and not a CycloneDX one.
