feat(sbom): preserve what a source document asserted, on ingest and on export (closes #396)#430bomly-guy wants to merge 3 commits into
Conversation
Phase 2.5, first half of #396. CycloneDX and the graph hop; SPDX, document assertions, the fixed-point test and hostile-document fuzz follow on this branch. `bomly scan --sbom --format spdx` silently dropped most of what its input asserted, because only coordinates, scope, copyright and licenses survived Document -> Graph -> Document. Supplier, originator, description, homepage, checksums, CPEs and the document's own external references now cross that hop as the typed SDK fields ADR-0037 defined for it. Every value clears an SDK gate at every crossing -- ingest and export both, not just the boundary that happens to be upstream. An ingested document is untrusted input Bomly re-emits under its own name, and the node in between is not a trusted carrier either: a detector or external plugin can write these fields directly, so a value can reach export having passed no ingest gate at all. That asymmetry was #391's last unfixed finding. The gates are the SDK's, never local: Contact.Normalized, ExternalReference .Normalized, Digest.Normalized, MergeExternalReferences for the set class. CPE grammar is reachable only through the reference gate, so a CPE is offered as a reference under both CPE types and admitted if either accepts it -- #396 records a hand-rolled CPE validator being retrofitted once already, its fuzz target breaking it immediately. Origin-derived reference types are deliberately NOT ingested. Bomly renders each origin as a distribution or vcs reference, and nothing in a document distinguishes ours from a third party's -- so ingesting them would let a detector assertion return as a source assertion and be re-emitted as one on the next hop, a detector claim laundered into a document claim across two conversions. TestOriginIsNotReadBackFromAnIngestedDocument already pinned the origin half of that rule and caught this when the reference half was missing. The cost is real and stated rather than hidden: a third-party document's own vcs or distribution reference is not preserved. Also bumps bomly-sdk to v0.9.3 for its merge-capacity hardening (bomly-dev/bomly-sdk#53), and applies the same bound to the CLI's own two `len(a)+len(b)` allocation hints in the SPDX encoder. Those lengths are attacker-influenced now that ingest carries a foreign document's assertions. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…ds them Second part of #396. SPDX both directions, the conversion acceptance test, and the hostile-document fuzz target. SPDX writes a contact as one line, so ParseSPDXContact and Contact.SPDXString do the reading and writing -- the grammar has an optional "(<email>)" suffix that must not be retained, and that is precisely the rule a second local reading forgets. Description prefers the fuller field and falls back to summary. Checksums, homepage, supplier and originator cross both ways. References keep the category SPDX stated, because the triple (category, type, locator) is the reference's identity and the category is an SPDX-only axis with no CycloneDX source value -- so an SPDX reference round-trips without being re-derived from the type alone. A CycloneDX-sourced reference has no category, and takes OTHER on the way out, which is the category SPDX provides for exactly that. Bomly's own projections are not read back as assertions. The purl and cpe references are written from Component.PURL and Component.CPEs on every run, so ingesting them would emit a second copy on the next hop and make the round trip grow. CPEs are instead read into Component.CPEs, which is the field they mean -- SPDX has no CPE field, so the reference list is the only place one can be, and dropping them outright lost the CPE the acceptance test asks for. FuzzIngestedAssertions drives arbitrary supplier names, URLs, descriptions, CPEs and digests through the ingest gates and asserts that whatever is stored still clears its own gate, and that a second ingest changes nothing. It found a real defect inside a minute, which is the reason #396 requires these from day one rather than after review. That defect is bomly-dev/bomly-sdk#54: NormalizeDescription is not idempotent. Invalid UTF-8 is replaced with U+FFFD at three bytes per bad byte, so a 3006-byte value normalizes to 9006 -- past the bound applied before the repair -- and the next pass, seeing an over-long value, returns empty. A description would survive one hop and vanish on the next, which is exactly the fixed point #396 requires. stableValue applies the SDK's own function until it settles and drops a value that will not, because publishing something that changes on the next hop is worse than publishing nothing. It goes when #54 ships; the fuzz target asserts the property either way. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The export surface takes the prepared graph entries alongside the graph,
so what each source document asserted about itself reaches the codec --
merging entries into one graph is precisely the step that discarded it.
With one source document the export adopts that document's identity
rather than minting a new one, which is what makes export -> ingest ->
export reproduce the same bytes. With several it mints its own and names
each source through a CycloneDX reference of type `bom`, because both
formats give a document exactly one identity.
The fixed-point test earned its place immediately: SPDX external
references were being emitted with the SDK's comparison-form category
("other") instead of the specification's spelling ("OTHER"), so an
ingested document changed case on its second export. SPDXName() is the
authority now.
Merged SPDX documents link nothing yet -- SPDX's externalDocumentRefs
requires a checksum over the source bytes that the SDK carrier cannot
hold. Filed as bomly-dev/bomly-sdk#55 and linked from the code.
Recorded as ADR-0042.

There was a problem hiding this comment.
When converting a single SPDX source, inheritDocumentIdentity copies its URI into doc.Namespace but cannot copy it into SerialNumber; CycloneDX then emits a newly minted serial and does not emit Namespace. This condition nevertheless suppresses the source link because the URI equals doc.Namespace, so the resulting CycloneDX document neither adopts nor links its source. Compare against the identity actually emitted by CycloneDX rather than the internal SPDX namespace.

There was a problem hiding this comment.
CycloneDX permits documents with neither serialNumber nor metadata, so a valid document containing only components produces empty DocumentAssertions and is omitted here. If that document is recursively merged with one identified SBOM, FromGraphEntries sees exactly one source, adopts that source's identity, and treats the merged graph as a conversion instead of minting an aggregate identity. Preserve the fact that an SBOM source existed even when it made no document-level assertions.

For a normal scan --sbom conversion, BuildOptions.Created is unset, so this field is initialized to the current time before source assertions are applied. Although the decoder stores the source timestamp in DocumentAssertions.Created, applySourceAssertions never copies it to doc.Created, and both encoders read doc.Created; consequently every conversion silently replaces the asserted timestamp. The fixed-point test masks this by explicitly pinning BuildOptions.Created.

When an SPDX package with PackageHomePage is converted, the value survives on Component.Homepage and the graph node, but this CycloneDX projection never maps it to a website external reference or any other field. The homepage therefore disappears from the generated CycloneDX document and cannot be recovered on the next ingest, despite homepage preservation being part of this change.

This helper is called only for entries in bom.Components. A valid CycloneDX document may instead describe its sole component only in metadata.component; the existing fallback adds that component after this loop without calling applyCycloneDXAssertions, so its supplier, publisher, description, hashes, CPE, and external references are all still discarded during ingest.

A source CycloneDX metadata.manufacturer or SPDX organization creator is ingested as a ContactKindOrganization, but this projection skips every non-person creator. Since metadata.Manufacturer is populated only from configured Bomly provenance, an ingested source organization disappears even in a same-format CycloneDX round trip. Map the source organization back to the document-level manufacturer slot when it is available.

Preserve source organization creators in CycloneDX metadata.
cycloneDXDocumentAssertions stores metadata.manufacturer as an organization creator, and FromGraphEntries preserves those creators for single-source and merged exports. However, CycloneDX export reads the manufacturer only from doc.Provenance.Manufacturer and emits only person creators as authors. When explicit provenance is empty, the organization creator is omitted. Set metadata.Manufacturer from the first organization creator, while keeping explicit provenance precedence. spdxDocumentCreators already preserves both creator kinds.

Preserve SPDX homepages in CycloneDX output
applySPDXAssertions and graph.go preserve Component.Homepage, but cycloneDXComponent does not emit it. When Component.Homepage is non-empty, emit a CycloneDX website external reference.
🐛 Proposed fix
refs := cycloneDXComponentReferences(comp)
refs = append(refs, cycloneDXEmittedReferences(comp.ExternalReferences)...)
+ if homepage := sdk.NormalizeHomepage(comp.Homepage); homepage != "" {
+ refs = append(refs, cdx.ExternalReference{Type: cdx.ERTypeWebsite, URL: homepage})
+ }
if len(refs) > 0 {

Detect CycloneDX self-links by serial number.
When a single SPDX source is converted to CycloneDX, source.Identity becomes doc.Namespace, while mintDocumentIdentity generates a separate doc.SerialNumber. The current comparison omits the source bom reference. Parse source.Identity with cdx.ParseBOMLink and skip it only when link.SerialNumber() == doc.SerialNumber.

Fold duplicate component assertions through the SDK merge rules. ToGraph discards the populated node when its canonical PURL already exists, so later assertions are lost. Use the SDK fold helper: scalar fields fill gaps, while set fields such as ExternalReferences, digests, and CPEs union.

Preserve a root component's publishable supplier.
spdx23Codec.encodeJSON renders c.Supplier first, then replaces it for every root when doc.Provenance.Manufacturer is set. A root with both values can therefore lose its source supplier during SPDX export. Use the provenance value only when no publishable supplier was rendered:

Closes #396. Phase 2.5 of the SDK maturity plan, on SDK v0.9.3.
bomly scan --sbom --path in.cdx.json --format spdxused to drop nearly everything the input asserted: only coordinates, scope, copyright and detection licenses survived the graph hop. This carries the rest through, in both directions, under the typed model ADR-0037 established — no metadata smuggling, which is what sank #391.What now survives
Per component — supplier, originator/publisher, description, homepage, checksums, CPEs, and the document's own external references with the category and type the source stated.
Per document — identity, name, data license, timestamp, credited people, organizations and tools, and the comment. These ride
GraphEntry.Document, which consolidation previously dropped when rebuilding entries.The headline acceptance criterion holds: a supplier-rich CycloneDX document converts to SPDX and back keeping supplier, publisher, description, checksum, CPE and its classified reference — asserted at every hop, including the graph hop where the loss actually was.
Two decisions the ADR left to implementation (ADR-0042)
The export surface takes the prepared entries, alongside the graph rather than instead of it. The graph is the one already selected for output — consolidation renamed its identities, the scope filter decided what stays — so rebuilding it from entries would export a different graph than the rest of the command reports.
A conversion restates its source; a merge links its sources. With one source document the export adopts that document's identity rather than minting one. That is not a stylistic choice: minting fresh would force the source identity to be carried as a link, and on the next ingest that link has nowhere to live, so every hop would differ and the fixed point #396 asks for would be unreachable by construction. With two or more, the document mints its own and names each source through a CycloneDX reference of type
bom.What the tests found
The fixed-point test caught a real defect on its first run: SPDX external references were emitted with the SDK's comparison-form category (
other) instead of the specification's spelling (OTHER), so an ingested document changed case on its second export.SPDXName()is the authority now.FuzzIngestedAssertionsfound bomly-dev/bomly-sdk#54 within a minute —NormalizeDescriptionis not idempotent, so a description would survive one hop and vanish on the next. Guarded locally bystableValue, marked for deletion when the SDK fix ships.All three new load-bearing assertions were mutation-checked: removing the export re-gate, suppressing the source links, and dropping identity inheritance each fail their test.
Known gap
A merged SPDX document links nothing. SPDX names another document through
externalDocumentRefs, and every entry requires a checksum over that document's bytes — computable only at ingest, andsdk.DocumentAssertionshas nowhere to keep it. Filed as bomly-dev/bomly-sdk#55, linked from the code and documented indocs/SBOM.md. Merged CycloneDX documents do link their sources, and merged SPDX documents still preserve every component assertion.Also deliberate: reference types
distributionandvcsare not ingested. They are the shape Bomly's own origin export takes, and nothing in a document distinguishes Bomly's emission from a third party's — so reading them back would let a detector's guess about where a package came from re-enter as though the document had asserted it. The cost is that a third-party document's genuine vcs/distribution reference is not preserved, which is narrower than one line of #396's acceptance sketch.
