feat: package origin as a first-class model field - #1
Merged
Conversation
An SBOM should say where each package came from, and only the component that read a manifest knows: 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 downstream is guesswork with a per-ecosystem counterexample for every rule, so the answer has to travel with the dependency. Add PackageOrigin, carried on Dependency and Package: - ArtifactOrigin and RepositoryOrigin record what a manifest said; both return nil rather than a wrong answer when the value is not publishable. - NormalizeOriginURL is the single rule every published location satisfies: absolute http(s), host present, non-empty path, no userinfo, re-serialized from the parse. Local paths, file://, ssh and scp-style remotes, "git+" prefixes, registry and index roots, and credentialed URLs are all rejected, so filesystem layout and secrets cannot reach a published document. - Normalized() applies that rule again on read, so an origin arriving from a plugin or a hand-built graph is held to the same standard as one from a built-in component. - ReconcileOrigin settles records of one package that a graph merge folds together. Absence is not a disagreement; two different assertions cancel and stay cancelled, because publishing whichever record a merge kept first would make the answer depend on traversal order rather than on the project. Graph merging and Package.MergeFrom reconcile rather than keeping the first record, which is where an arbitrary answer used to come from. The field is optional and omitted when empty, so protocol v1 payloads from older binaries decode unchanged and payloads carrying origin are ignored by them -- the contract stays strictly additive. This gives external plugins a supported way to assert origin, which they had no access to while the rule lived in a host's internal package. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Two additive fields, both optional, neither populated by anything yet. They exist so the facts have a typed home when a producer appears, rather than arriving as untyped metadata that every consumer has to guess at. Digest.Subject says what a hash covers. Empty means the published artifact, which is what nearly every ecosystem records, so existing producers keep their meaning unchanged. It exists because some hashes are not hashes of a file: a Go module's "h1:" value is SHA-256 over a manifest of the source tree's file hashes, not over the module zip, and a consumer that compares it against a downloaded file will always find a mismatch. Today that distinction is lost. Package.Attestations holds signed statements about how a package was built or published -- in-toto statements such as SLSA provenance. Bomly neither fetches nor verifies them; the type records what a matcher found and, importantly, whether it verified the signature. That flag is the part worth modelling: an unverified statement is weaker evidence, not proof, and the difference is the first thing lost when provenance is carried as free-form data. This commit is separable from the origin work and can be dropped if you would rather wait for a producer -- nothing depends on it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

…ttestations Three review findings, all real: - The registry seeding path skipped every occurrence of a package after the first, so a package resolved differently in two manifests kept whichever was walked first -- the exact order-dependence this work is meant to remove, on the path that actually feeds matchers. Every occurrence now reconciles onto the registry package; the package is still enriched once. - Hosts are case-insensitive, so "https://GitHub.com/owner/repo" and "https://github.com/owner/repo" name one place. Comparing them as strings made reconciliation read a disagreement and drop a perfectly good origin over formatting alone. The host is now lowercased; the path is left alone, being case-sensitive. - Attestations were kept first-wins, which discards statements when several components each attach one -- a provenance statement from one matcher and a signature from another. They now union, deduplicated by source, predicate type, URL, and digest, the way vulnerabilities already do. Where two records describe one statement and either verified it, the merged record is verified: verification is a fact a component established, not an opinion.

Hosts are case-insensitive, so two lockfiles writing one host differently name the same place. Comparing the URLs as strings made reconciliation read a disagreement and drop a perfectly good origin over formatting alone -- the merge rules added here turned a cosmetic difference into lost data. The host is now lowercased when a URL is normalized. The path is deliberately left alone, and a test asserts that two paths differing only in case still reconcile to a disagreement, so the fix does not over-reach. Found by review on the SDK port (bomly-dev/bomly-sdk#1), where the same rule lives; fixed in both. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

- Attestation merging promoted Verified across records sharing a source, predicate, URL, and digest -- but not an issuer. A record naming issuer A could come out verified because issuer B verified something else, and a record with no issuer could come out verified with no identity attached, which is the one thing a verified claim must have. Records now merge only when their issuers are compatible: equal, or one unknown. Two named issuers are two statements, because they are two signers. - A digest's Subject is part of a statement's identity: the same bytes hashed over a source tree and over an artifact are different claims. - An explicit default port names the same origin as no port at all, so "https://host:443/pkg" and "https://host/pkg" no longer read as a disagreement and discard a good origin. IPv6 literals keep their brackets, and a non-default port stays part of the location. - Empty and Normalized now answer one question. Empty read the raw fields while Normalized re-validated them, so an origin carrying an unpublishable value was not Empty but normalized to nil -- and the obvious guard-then-read pattern dereferenced nil. The two synthetic credentials in the tests are labelled as such, so a lint gate added later does not trip over the fixtures that prove credentials are rejected.

An issuerless verified record folded into one naming an issuer, reporting that
issuer as verified on the strength of a check that recorded no signer -- and
with several issuers, merge order decided which one received it. That is the
mirror of the case fixed in the previous commit, and it was still reachable.
Verification is a fact about a statement and a signer together, so records now
fold only when they agree on the issuer, or when one of them claims nothing
beyond the statement's existence -- no issuer and no verification -- in which
case it is replaced wholesale rather than contributing a field. A verified
record with no issuer is a real, weaker claim ("verified, signer unrecorded")
and stays its own record.
Tested in both merge orders, since order-independence is the property at stake.

… escapes - The rule was enforced on read, which meant an origin built by hand or by an external component could be stored, forwarded to the next plugin, and written back out without ever passing it. It now applies on unmarshal and on marshal, so a location that would be rejected on read cannot enter or leave the process. A recorded disagreement survives the trip: it is not a location, but it is a fact worth keeping. - Digests union instead of keeping whichever record merged first. With Subject, two records can carry genuinely different claims -- a hash of the artifact from one source, a hash over the source tree from another -- and dropping a later slice would lose provenance on merge order. - Escaped unreserved characters are decoded and remaining escapes written in one hex case, because RFC 3986 makes "%7Euser" and "~user" the same path; without this they reconciled to a disagreement and a valid origin was lost to formatting. The escape work canonicalizes the *escaped* form rather than parsed.Path. Path is already decoded, where "%2F" and "/" are indistinguishable, so re-encoding from it turned an escaped slash into a path separator and silently changed the location -- caught by a test asserting an escaped slash stays escaped.

* feat(detectors): add detector-asserted package origin 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> * feat(detectors): emit package origin from lockfile source fields 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> * feat(sbom): publish detector-asserted origin as download and repository 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): document detector-asserted package origin; cover it in smoke 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> * fix(sbom): address review — origin replacement, host roots, npm v1, round-trip docs - Setters replace rather than merge. A second assertion on the same node no longer leaves both origin forms behind, and an unpinned repository no longer inherits the previous one's revision -- which would have named a commit that repository may not contain. A rejected value still leaves an earlier origin intact. - A host root is rejected for artifacts too, not just repositories. It names a server, not a package, so "https://registry.example/" was exactly the registry-root case this feature excludes. - npm v1 lockfiles now publish origin. They have no packages map, so they resolve through the flat dependencies tree, whose node type dropped the "resolved" field those lockfiles do record. This also picks up `npm ls --json` output, which carries the same field. - Correct the SPDX round-trip claim: origin is written on export and not read back on ingest, so re-exporting an ingested document says NOASSERTION. The docs said the opposite; a test now pins the real behavior. - Correct the Component comment: registry enrichment can fill VCSURL beside an artifact URL, so "at most one" held only for detector-asserted origin. - Clarify in docs that a repository may be unpinned, and that the http(s) rule governs detector origin while SPDX composes it into git+<url>@<revision>. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(detectors): reconcile origin when one package appears more than once A lockfile can record the same package at several places in a tree, and the copies can disagree -- one nested under a package pinned to a private mirror, one at the top level from the public registry. They share a name and version, so they become one graph node. The flat npm path made that worse: it walked a map, so which copy won varied between runs of the same lockfile, and an SBOM that changes run to run is not reproducible. Every other node lockfile path already sorted its keys; this one now does too. Sorting alone would only make the arbitrary winner stable, so occurrences are now reconciled where a duplicate folds into an existing node. Absence is not a disagreement: an occurrence asserting nothing leaves an origin standing, and one asserting something fills a gap. Two different assertions cancel -- one node is one package, and omitting a location is honest where taking a side of a contradiction is not. Applied in the shared node helper, so npm, pnpm, yarn, and bun all get it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(detectors): keep origin conflicts sticky; pin native SwiftPM and pub runs Three findings from review, all real: - A disagreement between occurrences did not stay a disagreement. With copies claiming A, B, then A, the B conflict cleared the origin and the third copy stored A again -- publishing one side of a contradiction, which is what the rule added last commit was meant to prevent. The disagreement is now recorded under a metadata key that no later merge lifts. A detector setting an origin outright still supersedes it: that is an assertion about what was resolved, not a fold of two occurrences. - SwiftPM and pub have build-tool-backed primaries, and neither tool reports what this feature needs: `swift package show-dependencies` prints no revision, and `dart pub deps --json` prints no source description. So on a machine with swift installed, repositories exported unpinned; with dart installed, git packages exported nothing at all -- while the committed-file fallback exported both correctly. Each native path now reads its committed file back and joins the origins onto the graph, best effort. What Bomly reports no longer depends on which resolver ran. The join lives inside the function the detector calls rather than beside it, so deleting it fails a test instead of silently narrowing coverage -- the first version of this fix was tested at the helper and left the wiring uncovered. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(detectors): never credit a local checkout to the pin it replaced `swift package edit <name> --path ...` swaps a dependency for a local checkout while Package.resolved keeps the pin that checkout replaced. The pin lookup missed on the local path and fell through to matching by identity, so the SBOM claimed the edited local code came from the remote repository at that commit -- a false provenance claim, which is the failure this feature exists to avoid. Reproduced, then fixed by requiring the graph node's own source to be git: what the build resolved is the truth, and the committed file only supplies the commit the tool omitted. pub can reach the same state through dependency_overrides, so it gets the same guard. Also document that `--enrich` can attach a repository no lockfile claimed: the Scorecard matcher resolves one from package identity, which fills the vcs reference for packages whose detector reported nothing -- including ecosystems the docs list as yielding nothing, and Syft-detected packages. It is a network lookup rather than a manifest claim, carries no revision, and always loses to a detector-asserted repository. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(engine): settle package origin across manifests before graphs merge Each subproject is resolved on its own, so a package two of them share arrives as two nodes. The SDK's graph merge keeps whichever it meets first and discards the rest, so a recursive or multi-manifest scan would publish one subproject's answer for a package the scan saw resolved two different ways -- a monorepo where one workspace pulls from a private mirror and another from the public registry is enough to trigger it. ConsolidateGraphs now settles origin across the selected entries while both occurrences are still visible, and writes the verdict onto every one of them so the surviving node carries it whichever the merge keeps. The merge itself lives in the pinned SDK and is not changed here. A recorded disagreement is part of that verdict, which is why it is a metadata key rather than an absent value: absence would let a later fold refill it. The test proves that property directly rather than only observing an empty origin, after a mutation check showed the two were indistinguishable. This supersedes the earlier decision to leave cross-detector dedup alone: the rule is now the same at every level that folds occurrences together. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(cargo): cancel origin when one crate resolves from two sources Cargo can resolve one crate name and version from two sources -- the same crate pulled from two git remotes. They share a PURL, so they are one graph node, and the node kept whichever source was walked first. The walk was over a map, so the answer varied between runs of the same project: 40 runs of one fixture produced repository A 33 times and repository B 7 times. The package map is now walked in a fixed order, and cargo's node dedup reconciles origin the way the node detectors do, so disagreeing sources cancel instead of racing. Also correct what the docs say about enrichment. The Scorecard repository fills in whenever the detector reported no repository -- including for packages that already have a download location, which the text implied it skipped. An artifact and a repository answer different questions, so a package can carry both; SPDX now records the repository as source info in that case, where before it reached CycloneDX and vanished from SPDX entirely. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(detectors): nil-safe reconciliation and best-effort logging Three review points, all cheap and all real: - ReconcileOrigins is exported, so a caller can hand it a slice containing nil. It would have dereferenced through clearOrigin and panicked. Nil occurrences are now skipped, and a nil first element returns rather than reading its metadata. - The two committed-file joins take a logger and log at debug when a file will not parse, which is exactly where a nil logger bites. Both now fall back to zap.NewNop(), which is the convention this repo states. - Two tests walked a graph asserting on a named node without requiring it to be there, so they would have passed if construction dropped it. Both now count what they checked -- verified by removing the node and watching them fail. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(detectors): treat host casing as the same location Hosts are case-insensitive, so two lockfiles writing one host differently name the same place. Comparing the URLs as strings made reconciliation read a disagreement and drop a perfectly good origin over formatting alone -- the merge rules added here turned a cosmetic difference into lost data. The host is now lowercased when a URL is normalized. The path is deliberately left alone, and a test asserts that two paths differing only in case still reconcile to a disagreement, so the fix does not over-reach. Found by review on the SDK port (bomly-dev/bomly-sdk#1), where the same rule lives; fixed in both. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(detectors): treat a default port as the same location "https://host:443/pkg" and "https://host/pkg" name one place, but comparing the URLs as strings made reconciliation read a disagreement and drop a good origin over formatting -- the same class as the host-casing fix, found by review on the SDK port (bomly-dev/bomly-sdk#1) and fixed in both. IPv6 literals keep their brackets, and a non-default port stays part of the location. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(detectors): reject ports nothing can connect to url.Parse only checks that a port is numeric, so "https://host:99999/pkg" was accepted and would have been published as a location no client can reach. Ports outside 1-65535 are now rejected. Found by review on the SDK port (bomly-dev/bomly-sdk#1); fixed in both. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix: settle origin when two nodes collapse to one identity Two findings, both producing false provenance: - A single manifest can record one package twice with different locations -- a Bun lockfile listing one name and version from two mirrors. Identity normalization collapses both nodes onto one canonical PURL and keeps the first, so the SBOM published one mirror as authoritative. Cross-manifest reconciliation could not help: it runs later, and returns early for a single-manifest scan. The collapse now reconciles origin while both occurrences are still there. - SwiftPM repository matching lowercased the whole URL, so on a case-sensitive host "/Team/Helper" and "/team/helper" shared a lookup key and a package could take the pin belonging to a different repository. Only the scheme and host are case-insensitive; the path keeps its case. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * refactor: adopt the SDK's package origin (bomly-sdk v0.4.0) Origin began as CLI-internal metadata keys because promoting it needed an SDK release. bomly-sdk v0.4.0 has it as a typed field, so the CLI now uses that and deletes its own copy. - Detectors assign `dep.Origin` from `sdk.ArtifactOrigin` / `sdk.RepositoryOrigin` instead of calling internal setters. External plugins can now do the same, which was the point: the rule they need was unreachable inside `internal/`. - Export reads `pkg.Origin.Normalized()`, which applies the same validation the CLI used to perform on read. - `internal/detectors/origin.go` and its tests and fuzz target are gone; the SDK carries the rule and its own fuzzing, and it validates at the JSON boundary too, which the CLI's version never did. - The origin filter in `output.cloneRefMetadata` is gone. It existed to keep metadata keys out of command payloads; a typed field never reached them, because those documents are built from explicit projections. - Cross-manifest reconciliation in `ConsolidateGraphs` is gone: the SDK's graph merge now reconciles. The tests that covered the behavior stay and pass unchanged, which is what makes the deletion safe. Reconciliation the SDK does not own -- node and cargo node dedup, and identity collapse in `normalizeGraphPackageIdentity` -- stays here, now calling `sdk.ReconcileOrigin`. Generated schemas pick up `Digest.Subject` from the SDK; it is omitempty, so scan output is unchanged for every package that does not set it. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(swiftpm): do not credit a package to a pin for another repository A package can be built from a mirror while Package.resolved still pins the upstream host. The names match, so the identity fallback attached the pinned repository and its commit to a package that was never fetched from there -- reproduced: a node resolved from mirror.corp came out claiming git.corp at a specific revision. Matching by identity is now only used when the graph offers nothing better. A node that names a repository and did not match one has a repository the pins do not describe, and a same-named pin is a guess rather than evidence. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore: tidy go.sum after the SDK bump `go get` leaves the previous version's hashes in place; the tidy-drift check catches it. Removes the stale bomly-sdk v0.3.0 entries. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(cargo): do not credit a workspace member to a same-named crate Cargo.lock can hold two entries with one name: the project's own workspace member, and an unrelated crate of the same name pulled from a git remote. The member is looked up by name alone, so it could take the external entry and, with it, that repository and revision -- reproduced as a node typed application and sourced workspace, meaning first-party local code, claiming github.com/external/helper at a commit. A workspace member is the project's own code and has no external origin, so neither node path sets one for it. The name-collision lookup itself is pre-existing behaviour and left alone; this only stops it producing false provenance. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * docs: correct the round-trip claim in the architecture record The decision entry still said a resolved commit survives an SPDX round trip. It does not: the SPDX decoder never reads PackageDownloadLocation and ToGraph reconstructs no origin, so re-exporting an ingested document says NOASSERTION -- which `TestOriginIsNotReadBackFromAnIngestedDocument` asserts. The public docs were corrected earlier and this copy was missed, leaving maintainers the opposite guarantee from the implementation. It now says what is true: a revision is expressible in SPDX output and not in CycloneDX output, and neither survives ingest. The test's failure message names both documents, since this claim has drifted once already. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * chore: pin bomly-sdk v0.4.1 Picks up numeric port normalization, so one port written two ways -- ":0443" and ":443", or ":08443" and ":8443" -- is one location rather than a disagreement that discards a valid origin. Also carries the LICENSE fix that makes the module's Apache-2.0 licence machine-detectable, which is what the code-scanning alert on this PR was reporting. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(pipenv): reconcile origin across dependency groups A package can be listed in both default and develop with different sources. The groups produce one node, and the second was discarded whole, so the node published the default group's source rather than recording that the lockfile says two things -- reproduced with a package whose develop entry names a private mirror. Same reconciliation the other fold points use, so two groups that agree keep their origin and two that disagree cancel. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(uv): reconcile origin when records fold to one node A universal uv.lock can hold several records for one package. The name index overwrote unconditionally, so the last record's node reached the graph and the earlier one's origin went with it -- reproduced with two records naming a public archive and a private mirror, where the SBOM published the mirror purely because it was listed second. Last-wins for the node itself is unchanged; only the origin now accounts for the records being replaced, so two that disagree cancel. This is the sixth place where records of one package fold together and the rule has to be remembered. The architecture entry now lists them and says plainly that the durable fix is for whatever owns node identity to reconcile, rather than every caller. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * refactor: give origin reconciliation one home, and record the principle Seven places fold two records of one package into one node, and each had to remember to reconcile origin. They accumulated one review round at a time -- node dedup, cargo dedup, identity collapse, pipenv's groups, uv's name index, the cross-manifest merge -- because a rule written out by hand at each site is a rule that gets forgotten at the next one. Poetry, the seventh, had been forgotten exactly that way. All of them now call `detectors.FoldOrigin`, which names what the caller is doing rather than what to type. Reconciliation is symmetric, so the argument order cannot be got wrong: a graph keeps the node already present, a name index keeps the incoming one, and both fold to the same answer. `TestOriginReconciliationGoesThroughFoldOrigin` fails if a hand-written reconciliation reappears under internal/, which is what stops the eighth site from repeating the pattern. AGENTS.md and CLAUDE.md gain the general principle, since this was not specific to origin: when the same defect can recur at more than one call site, centralize the rule instead of patching sites, and add a guard when the rule can be bypassed by writing it out by hand. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * refactor: one node-insertion helper, so folding cannot be forgotten Centralizing the reconciliation rule last commit was not enough: thirteen detectors each carried their own copy of "add this node unless it is already there", all written before origin existed, and eleven silently dropped the duplicate's origin. A rule with one home still gets missed when the operation that must apply it has thirteen. Node insertion now goes through `detectors.AddNodeFolding`. Detectors keep their thin wrappers where they had them, but the folding lives in one place and a detector written later inherits it instead of having to know. A second guard, `TestNodeInsertionGoesThroughTheSharedHelper`, fails when a file looks up a node and inserts it by hand. It found four sites nobody had reported -- gomod, gradle, maven, and a second insert in pipenv -- which is the argument for guards over vigilance. The reported pip-inspect case is covered by a test: an environment reporting one distribution twice with different direct_urls now cancels rather than publishing whichever came first. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(swiftpm): one list of Package.resolved locations Where a SwiftPM lockfile can live was written out in three places that had drifted apart. Position attachment knew about Xcode's copy inside the workspace; the fallback detector's read did not, and the native origin join inherited that list when I copied it. A project keeping its only lockfile there was therefore detectable and annotated with line numbers, but its repositories came out unpinned, and the fallback detector could not read it at all. The locations are now one list that reading, evidence detection, and position attachment all use, so a fourth consumer cannot drift again. Evidence order now puts the manifest last, behind every lockfile, which is what the detector actually prefers. Generated support matrix and its test expectation follow the corrected list. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix: folding never gives first-party code an external origin Folding treats an absent origin as a gap to fill, which is right for two records of a consumed package and wrong for the project's own code: a published package sharing a workspace member's name and version would hand over its download location, and the SBOM would report first-party code as coming from someone else's registry entry. Detectors already decline to set an origin on these nodes -- npm clears it for workspace members, cargo skips it for application nodes, SwiftPM ignores local checkouts -- so the invariant existed but folding did not know about it. It now lives with the fold, which is the only place that can add an origin a detector did not set. I could not reach this end to end: in both cargo and npm the external record happens to sort first and becomes the surviving node, so ordering hides it today. That makes this hardening rather than a demonstrated fix, and it is worth having precisely because the protection currently rests on sort order. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test: cover CycloneDX round trip; tidy a displaced comment The round-trip rule is about ingest rather than about a format, so the test now re-ingests and re-exports CycloneDX as well as SPDX and asserts no references survive. Also moves the originOf doc comment back to the function it describes; an inserted test had split them. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * refactor: adopt DependencyOrigin (bomly-sdk v0.4.2) — occurrences stay distinct Adopts the simplified origin model and applies the rule agreed in review: identical records fold, a gap fills, and contradicting records stay distinct nodes -- no tiebreak ever picks a winner over a contradiction. - FoldOrigin, the first-party guard, and the reconciliation guard are gone with the SDK machinery they wrapped. Node insertion keeps its one home, renamed detectors.EnsureNode, which deliberately merges nothing: records that differ deserve distinct nodes, and records that are the same need nothing merged. - One-node-per-PURL is the registry's constraint, not the graph's. Cargo's metadata path now keeps contradicting same-name@version records as distinct nodes under source-qualified IDs, with resolve edges attached to the exact occurrence each parent depends on. normalizeGraphPackageIdentity preserves detector-split occurrences through the canonical-PURL rewrite instead of collapsing them, and preserveContradictingOccurrences re-IDs cross-manifest contradictions before the SDK merge, so the merge folds only witnesses of one resolution and fills only gaps. - Bare-name lockfiles (uv, poetry, pipenv groups, npm v1's nested tree) keep one node per identity: the deterministic first/last record wins as a whole, with no field-level mixing. Their tests now pin the specific winner and repeat runs to catch order-dependence. - TestExportNeverReadsResolvedURL makes the raw manifest value structurally unreachable from the export layer: internal/sbom cannot name ResolvedURL, only Origin.Normalized(). - Architecture record and the agents-file examples updated: the "fix at the right depth" bullets now cite EnsureNode and the two surviving guards. Output for scans without duplicate records is byte-identical to v0.4.1 (verified on real npm and cargo projects plus the SPDX validator); the only behavior change is that a contradiction now yields two truthful components instead of one arbitrary winner. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(cargo): split occurrences on source difference, not origin conflict Cargo permits one name@version from a registry and a git remote at once (renamed dependencies). The split keyed on origin conflict, and a registry occurrence has no publishable origin, so OriginsConflict said false: the registry occurrence vanished into the git node, conflating their edges and crediting registry-pulled code to the repository -- reproduced. The true signal was always the manifest's own assertion: two cargo package IDs with different source strings are two resolutions, whether or not both yield a publishable origin. The split now compares sources, which subsumes the git-vs-git conflict case and also keeps a sourceless workspace member from absorbing an external record on this path. Also deletes the obsolete origin-reconciliation paragraph from the architecture record -- it mandated detectors.MergeOrigin, deleted two rounds ago, directly above the paragraph stating the current no-merge policy. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: opaque occurrence IDs; occurrence-aware Cargo.lock and npm paths Three review findings against the occurrence work, all applied: - Node IDs become SBOM component identifiers (CycloneDX bom-refs, SPDX element IDs), and the cargo split embedded the raw source string in the second occurrence's ID -- a credentialed git URL would have ridden a bom-ref past every origin check. Occurrence IDs now qualify with a hash of the distinguishing value, never the value itself: detectors.OccurrenceID. - The Cargo.lock fallback still folded source-qualified records by name@version, and worse, its bare byName map silently dropped edges written in cargo's qualified dependency form ("name version (source)") -- the very form cargo uses precisely when a name is ambiguous. A shared lockIndex now assigns occurrence-aware node IDs and resolves dependency strings at whatever precision the lockfile wrote, in both the plain and workspace fallbacks. - npm v2/v3 lockfiles can install one name@version from different tarballs at different package paths. Both records now stay as distinct occurrences keyed by the path -- the stable positional identity npm already has -- and pathToID wires each position's edges to its own occurrence. All three mutation-checked; scans without duplicate records are unchanged. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: one collision helper; occurrence IDs keyed by origin, not manifest Two review findings, both taken at the depth they pointed at: - The occurrence-split shape had been hand-written at a fifth site. It now has one home, detectors.EnsureOccurrence: insert, fold same-resolution records, and keep a different-resolution record as a distinct occurrence under an opaque qualifier-derived ID. Cargo (metadata, lock, workspace), npm, yarn, and pnpm all route through it -- yarn's selector entries and pnpm's lockfile keys pinning one name@version to different tarballs now survive as distinct occurrences instead of the first absorbing the rest. - Cross-manifest occurrence IDs were derived from the manifest path, so three manifests resolving origins A, B, B produced two different IDs for B and the merge kept two identical components -- with the count depending on walk order. The ID is now derived from the normalized origin itself: identical witnesses land on one occurrence ID and fold, whatever the order. Tested across all three orderings of A,B,B. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: within-manifest occurrence IDs keyed by origin; npm descriptor tracks survivor The cross-manifest fix taught occurrence IDs to derive from the origin so identical witnesses fold; the within-manifest branch still kept every detector-position ID, so one lockfile recording origins A, B, B produced three components with B's edges split across two. The same origin-keyed rule now applies one level down: a repeated contradiction folds into its occurrence, pinned by the A,B,B case in the within-manifest test and mutation-checked. The npm workspace module descriptor now records surviving.ID -- the same node pathToID records -- rather than the candidate's. The two are string-equal on every current path, so this is hardening rather than a fix, but the descriptor should not depend on that equality holding forever. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: occurrence identity is a pure function of (package, origin), scan-wide An origin's ID still depended on arrival order: the first record in each entry kept the canonical PURL ID while later ones took origin-derived hashes, so two manifests carrying the same origins in opposite orders gave one origin two IDs -- {canonical:A, hash(B)} in one entry and {canonical:B, hash(A)} in the other -- and the merge emitted origin A twice with split edges. Mixed contested and uncontested entries hit the same fault through the established-first path. The pass is now two phases and one rule: collect the distinct origins per canonical package across the scan; where there is more than one, every node of that package -- including whichever held the canonical ID -- takes the ID derived from its own origin. Same origin, same ID, regardless of entry, order, or who arrived first; a node with no origin keeps the canonical ID as its own "resolution unknown" occurrence. Pinned by opposite-order and mixed contested/uncontested cases; mutation- checked by exempting canonical-ID holders from the rename, which fails both. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: consolidation discriminates occurrences by resolution, not origin conflict The detectors learned to split occurrences on the manifest's own resolution strings; consolidation still split on origin conflict. A registry record has no publishable origin, so it read as compatible with anything: consolidation re-collapsed the registry-vs-git pair the detector had preserved and gap-filled the git origin onto the survivor -- falsely attributing registry-fetched code within one manifest, and again across two. One discriminator now serves both levels: resolutionKey is the normalized origin when one is publishable, else the manifest's raw resolution string -- used only for identity and hashing into occurrence IDs, never published. Records with neither fold as before, so gap-filling for genuinely origin-silent records is unchanged. Pinned within-manifest and across manifests; mutation-checked by reverting the key to origin-only, which fails both. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: rename occurrences before recording roots; first-party keeps identity Occurrence renaming ran after RootManifestID had been copied into the consolidated manifests and subprojects, so a renamed entry root left both records pointing at a node that no longer exists -- breaking manifest-to-root navigation. Renaming now runs first, and root IDs are recorded from whatever each entry's nodes are actually called; the rename maps are per entry, since one canonical ID can become different occurrence IDs in different entries. First-party records are exempt from renaming entirely: the project's own node is not an occurrence of an external resolution, so it keeps its identity -- a uv editable project consumed as a git dependency elsewhere keeps its canonical ID while the external record is renamed away from it. Its resolution still counts toward contest detection, so the external record cannot fold into the project and hand it an origin. Pinned three ways: a first-party root keeps its ID and gains no origin; a renamed non-first-party root's stored IDs follow it (asserted for manifests and subprojects); and both are behaviorally mutation-checked -- the earlier remap mutation only failed compilation, which proves nothing, so it was replaced with one that compiles and fails the assertion. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: v1 tree occurrences split on resolved; first-party contests when empty Two review findings on the remaining fold paths: - The npm v1 tree (and npm ls output) folded every duplicate under one ID: EnsureNode deliberately merges nothing, so two positions pinning different tarballs conflated their edges and shared the first record's artifact. The walker now carries ResolvedURL and routes through EnsureOccurrence with the resolved string as discriminator -- distinct resolutions stay distinct occurrences with per-position edges, identical ones fold. The earlier "deterministic first-wins" behavior and its test are superseded. - The first-party rename exemption left the fold path open: a workspace member's ResolvedURL is deliberately empty, so its record read as uncontested, the external record sharing its PURL kept the canonical ID, and the merge collapsed the application into the fetched dependency. resolutionKey now treats an empty first-party record as a resolution in its own right -- the local source tree -- so the external occurrence is renamed away from it. Ordinary records with no resolution stay empty-keyed, keeping gap-fill for origin-silent records intact (asserted by the existing gap cases). Both mutation-checked with compiling mutations. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(sbom): scorecard repository is never attributed to project-owned components The registry package is shared by every occurrence of a PURL, and matching rightly excludes first-party nodes from requests -- but export enriched per PURL, so a workspace member or fork sharing an identity with a consumed package took the consumed package's scorecard repository as its own vcs reference. The gap-fill now skips project-owned components; the consumed occurrence keeps the repository. "Is this the project's own record" was also on its third hand-written copy, so it now has one home, detectors.IsProjectOwned, used by consolidation's rename exemption, the first-party resolution sentinel, and this guard alike. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix: the canonical ID belongs to the project's record, whatever the order Within-entry normalization gave the canonical PURL ID to whichever record sorted first. Node order is deterministic, but it is ownership-blind: an external record could stably hold the canonical ID while the project's own member -- exempt from later renaming precisely to keep its identity -- sat on an occurrence hash. The two halves of the first-party rule contradicted each other. The collision branch now reserves the canonical slot: an external record that normalized first moves to its occurrence ID, its already-recorded source mappings move with it so edges follow, and the project's record takes the canonical ID. Two project records of one module fold as before. Pinned in both sort orders, with the consumer's edge asserted to follow the displaced external occurrence; the swap and the edge remap are separately mutation-checked with compiling mutations. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(sbom): project-owned components publish no origin, whoever asserted one Built-in detectors never assert an origin on the project's own records, folding cannot add one, and the scorecard fallback skips them -- but the export projection itself was unconditional, so a plugin-supplied graph could assert an origin directly on a first-party node and have it published, attributing local workspace or fork code to an external location. The projection now applies the same ownership guard, closing the last path. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(consolidation): folding witnesses keep every witness's usage facts When a repeated identical resolution collided on an occurrence ID (A, B, B), the taken branch silently dropped the later clone: edges remapped to the survivor, but its scopes, locations, and relationship vanished. The plain same-key fold had the same gap -- it only gap-filled origin. One foldWitness helper now owns the rule -- usage facts aggregate, origin fills its gap -- and every fold site routes through it: the same-key fold, the project-owned fold, and the occurrence-ID collision. Pinned by TestConsolidateGraphsFoldedWitnessesKeepUsageFacts (both witnesses' scopes and locations survive, the other occurrence's don't leak, in every record order); a compiling mutation dropping the collision-branch fold fails it. Addresses Codex review on PR #397. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(consolidation): project-ownedness is part of resolution identity A project-owned record that itself carried an asserted origin took the origin key, so an external record with the identical origin read as the same resolution and folded with it -- within one entry through the fold branch, and scan-wide too, since the split then saw one distinct key and let the graph merge collapse them. When the external record survived the fold, IsProjectOwned turned false downstream and export published the origin the project-owned component suppresses. resolutionKey now checks project-ownedness first: the project's record resolves from the local source tree, whatever origin metadata a producer stapled onto it. That one ordering fixes both levels -- the within-entry switch and preserveContradictingOccurrences already keep records with distinct keys apart. Pinned by TestProjectRecordsNeverFoldWithMatchingExternalResolutions (both visit orders within an entry, plus the cross-manifest split); the reverted ordering is a compiling mutation that fails all three subtests.

Makes package origin native to the SDK, so any component — including external plugins in their own modules — can say where a package came from.
Context: bomly-cli#397 implements detector-asserted origin behind CLI-internal metadata keys. Review flagged that external plugins cannot reach it: Go's
internalrule means a plugin can only participate by hardcoding private key strings and reimplementing a security-sensitive validation rule. This moves the contract here.Commit 1 —
PackageOrigin(the ask)A typed field on
DependencyandPackage:ArtifactOrigin/RepositoryOriginrecord what a manifest said, returningnilrather than a wrong answer when the value is not publishable.NormalizeOriginURLis the single rule: absolute http(s), host present, non-empty path, no userinfo, re-serialized from the parse. Local paths,file://, ssh and scp-style remotes,git+prefixes, registry and index roots, and credentialed URLs are rejected — filesystem layout and secrets cannot reach a published document.Normalized()applies that rule again on read, so an origin from a plugin or hand-built graph is held to the same standard as one from a built-in component.ReconcileOriginsettles records a merge folds together. Absence is not a disagreement; two different assertions cancel and stay cancelled.Merging changed behavior deliberately.
MergeGraphandPackage.MergeFrompreviously kept the first record and discarded the rest, so a package resolved differently in two manifests published whichever the merge happened to reach first. They now reconcile. This is the fix the CLI currently works around from outside; once this releases, that workaround can be deleted.Disputedis a field rather than an absent value on purpose: absence lets a later merge refill a value the project never agreed on.Commit 2 — provenance carriers (separable, drop if you prefer)
Two optional fields, neither populated by anything yet:
Digest.Subject— what a hash covers. Empty means the published artifact, so existing producers are unchanged. It exists because some hashes are not hashes of a file: a Go module'sh1:is SHA-256 over a manifest of source-tree hashes, not over the zip, and a consumer comparing it against a downloaded file always finds a mismatch. That distinction is currently lost.Package.Attestations— in-toto/SLSA statements, with aVerifiedflag. The flag is the part worth modelling: an unverified statement is weaker evidence, not proof, and that's the first thing lost when provenance rides in untyped metadata.I kept this to shapes that are externally standardized or grounded in a problem we already hit. Considered and deliberately left out: a
RegistryURLfield (registry roots are excluded by design — adding one invites the mistake back), an originSubpathfor packages living in a repository subdirectory (real for pub and cargo, but no producer today), and supplier/publisher identity (needs registry-native metadata and new network hosts — the open half of bomly-cli#380). Happy to add any of these if you want the carrier ready.Compatibility
Strictly additive within protocol v1, per
wire_compat_test.go: both fields are optional and omitted when empty, so payloads from older binaries decode unchanged and payloads carrying the new fields are ignored by them. Tested explicitly, including that an absent origin never serializes.Verification
go test ./...,go vet ./..., gofmt clean,go mod tidyno drift.FuzzPackageOrigin: 6.7M executions, no failures. It asserts that anything readable back is an absolute http(s) URL with a host and no credentials, that reconciliation is idempotent, and that two different origins never settle on one.MergeGraph,Package.MergeFrom), including the three-record A/B/A case that must not settle on A.Follow-up (not in this PR)
After a release, bomly-cli migrates from its
