refactor: DependencyOrigin — one concept, no merging, clear siblings - #3
Conversation
A dependency origin (asserted by a manifest, distilled by a detector) is not a package source (resolved from a registry during enrichment). The model now says so structurally rather than by convention: - PackageOrigin is renamed DependencyOrigin and lives only on Dependency. The name follows the two standards that record this concept as a structured value: Go modules' Origin (URL, ref, hash) and PEP 610's "Direct URL Origin". Manifests variously say "resolved", "resolution", or "source"; "source" is taken by the DependencySource kind enum, and "resolution" collides with version-solving vocabulary. - Package.Origin is gone. A registry package is one occurrence per PURL and position-free; the only enrichment-derived source repository remains PackageScorecard.Repository, which was always distinctly named. The registry seeding helper no longer touches origin. - ReconcileOrigin and the Disputed flag are gone. Merging origins was machinery for a case the model does not represent: occurrences that genuinely differ are different graph positions, not a conflict to resolve. Graph merging now fills gaps -- locations union, relationship merges, and an origin fills in from whichever record has one, so it survives regardless of manifest order -- and on a genuine conflict the existing record's origin stays, deterministically. Same fill-if-empty convention Package.MergeFrom has always used. - ResolvedURL stays a sibling field on both types, documented for what it is: the manifest's resolution field verbatim on Dependency (raw evidence the origin is distilled from, never published), and detection-time transport for matchers on Package. - Digest/DigestSubject and PackageAttestation move to their own files (digest.go, attestation.go), joining Coordinates as shared types with a file each. Pure moves. Wire compatibility: the origin JSON key is unchanged; a payload carrying the removed "disputed" field decodes as its remaining values (unknown fields are ignored), and old binaries never emitted values alongside it. The nine plugin repos pin SDK v0.3.0 and reference none of this API. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

📝 WalkthroughWalkthroughThe SDK adds package attestation and digest models. It renames ChangesAttestation and dependency-origin update
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This refactor changes how dependency origins are retained during graph merging, but a decoded empty origin can currently prevent a later valid origin from being preserved, and two new test fixtures fail the repository's lint check. Merge readiness therefore requires fixing the origin gap-fill condition and lint directives; the remaining issues are limited cleanup and documentation follow-up. Sequence Diagram(s)sequenceDiagram

UnmarshalJSON leaves a non-nil zero Origin behind when a recorded value fails validation, so a graph decoded from JSON carries non-nil origins that name no location. The merge's nil check read those as "present" and refused the fill, dropping the only publishable origin and making the outcome depend on which graph decoded first. The gap check is now Empty(), which is nil-safe and asks the question the rule actually means. Also from review: the dead first-nonempty digest fallback that mergeDigests already subsumes is removed; mergeDigests moves to digest.go with its type; the UnmarshalJSON doc no longer describes the deleted disagreement record; and the two synthetic-credential fixtures carry the nolint justification the rest of the file uses.

Model simplification agreed in review of bomly-cli#397: a dependency origin (asserted by a manifest, distilled by a detector) is not a package source (resolved from a registry during enrichment), and the model should say so structurally rather than by convention.
What changed
PackageOrigin→DependencyOrigin, living only onDependency. Naming follows the two standards that record this concept as a structured value — Go modules'Origin{URL, Ref, Hash}and PEP 610's "Direct URL Origin". Manifests variously sayresolved(npm/yarn/bun),resolution(pnpm/Berry), orsource(cargo/uv/poetry/pub);sourceis taken by theDependencySourcekind enum, andresolutioncollides with version-solving vocabulary. The precedent is cited in the type doc so the name is traceable.Package.Originis deleted. A registry package is one occurrence per PURL and position-free. The only enrichment-derived source repository remainsPackageScorecard.Repository, which was always distinctly named.PackageFromDependencyand the matcherkit seeding helper no longer touch origin.ReconcileOriginandDisputedare deleted. Merging origins was machinery for a case the model doesn't represent: occurrences that genuinely differ are different graph positions, not a conflict to resolve. Graph merging is now a merger of both in the fill-gaps sense: locations union, relationship merges, and an origin fills in from whichever record has one — so it survives regardless of manifest order — while on a genuine conflict the existing record's origin stays, deterministically. This mirrorsPackage.MergeFrom's fill-if-empty convention. −597/+391 overall.ResolvedURLstays a sibling field, now documented for what it is: the manifest's resolution field verbatim onDependency(raw evidence the origin is distilled from — may be a pseudo-URL, index root, or local path; never published), and detection-time transport for matchers onPackage(repository resolution reads it — released plugin contract, so the name stays). The triad is stated on the field:ResolvedURLis parsed,Originis asserted,Normalized()is the view consumers publish.Shared types get their own files:
Digest/DigestSubject→digest.go,PackageAttestation+ methods →attestation.go(pure moves;Coordinatesalready had its own).Compatibility
originJSON key is unchanged. A payload carrying the removeddisputedfield decodes as its remaining values (unknown fields are ignored), and old binaries never emitted a location alongsidedisputed:true, so nothing mis-decodes.bomly-plugin-*repos pin SDK v0.3.0 and reference none of this API — verified zero usage.bomly-cli(the only consumer of v0.4.x) migrates in the same coordinated change, as with v0.4.0.Verification
FuzzDependencyOrigin30s clean.TestMergeGraphFillsOriginGapspins fill-if-empty + existing-stays-on-conflict; both branches mutation-checked (deleting the fill, and inverting it to always-overwrite, each fail a test).Follow-up after release (planned as v0.4.2): bomly-cli PR #397 adopts this, deletes its fold machinery, and preserves distinct same-
