Closes #410. Phase 2.4, plus the bomly-sdk v0.9.2 adoption folded in.

The defect

SPDX 2.3 has no free-text license field — licenseDeclared must hold a valid expression, NOASSERTION, NONE, or a LicenseRef. Bomly wrote an unrecognized value verbatim, so a package declaring see LICENSE file produced a document a strict consumer can reject.

The quieter half was the mixed-validity fallback: a set of one recognized and one unrecognized license kept only the first and dropped the rest. A comment called that deliberate, because composing free text would produce something that does not parse. It was still a silent loss of a license a source had actually declared.

before after
see LICENSE file written verbatim into licenseDeclared LicenseRef-bomly-<hash>, with the text in hasExtractedLicensingInfos
MIT + non-standard MIT (second dropped) MIT AND LicenseRef-bomly-<hash>
MIT unchanged unchanged
nothing NOASSERTION NOASSERTION

Ingest resolves an atomic reference back to its text, so a round trip returns see LICENSE file rather than the hash. A compound expression naming a reference among other terms is left alone: it has no single text to become, and substituting free text into it would produce something that no longer parses. A foreign document's own reference-to-text pairing is taken as stated rather than re-minted — there the document is the authority, not our hash.

SDK v0.9.2 adoption

v0.9.2 closes both SDK issues this branch's predecessors filed, so the workarounds they left behind go with it:

  • sdk#43 → NodePURL. The node-to-purl projection existed twice here, deliberately: internal/graphview for the renderers and internal/sbom for the codec, because a codec importing the CLI's output layer inverts the layering. Both were commented as converging on the accessor once it shipped. It shipped; both delegate. graphview keeps ChildrenAmong and TopLevelParentIDs, which are CLI policy rather than model semantics.
  • sdk#39 → PEP 440 canonicalization before minting. Two spellings of one PyPI release fold again. TestPythonVersionCaseIsNotFoldedYet existed to make that gap visible rather than silent, and its own failure message said to fold the case back and delete it once a normalizer arrived — done exactly that.

Delegation check

  • LicenseRef-* minting, idstring safety, collision-freedom: spdxkit.MintLicenseRef — delegated. It hashes the whitespace-normalized text, so the identifier is deterministic and collision-resistant across components assembled without coordination, and confined to the characters SPDX allows.
  • Recognized vs free text: spdxkit.Classify. Expression composition: spdxkit.Compose. Reference enumeration on ingest: spdxkit.LicenseRefsIn — so a reference is what the grammar says one is, not a prefix match.
  • Node package URL: sdk.NodePURL.
  • CLI-owned policy: which values classify how, where extracted texts attach, how ingest maps them back, what a document may name, what counts as a top-level parent.

Verification

make verify SMOKE=1 green, zero golden drift on both halves. No fixture carries an unrecognized license, and the fixtures' PyPI versions are already canonical (pip, poetry and uv all write normalized versions) — so the PEP 440 change reaches only the hand-written requirements case it was filed for. That is exactly why the new tests drive the behaviour directly rather than relying on goldens.

Every acceptance criterion from the issue has a test, each mutation-checked:

  • reference minted with its text emitted, and the raw value never reaching the field
  • a recognized license mints nothing
  • two components sharing a text share one reference and one entry
  • distinct texts do not collide; identifiers are well-formed and minting is deterministic
  • round trip recovers the original text

FuzzSPDXLicenseValue now asserts the stronger invariant the issue implies: whatever the input, the field is NOASSERTION or parses as an SPDX expression, and every minted reference is both valid for its text and named by the field.

docs/SBOM.md and ADR-0035 drop the limitation they recorded. The ADR gets a dated note rather than a rewritten body — it recorded a decision that was true when made — and the note also redirects its internal/licenseexpr references, since #428 deleted that package.

Summary by CodeRabbit

  • Bug Fixes
    • SPDX output now converts unrecognized license text into valid LicenseRef-* identifiers while preserving the original text.
    • Mixed recognized and unrecognized license sets now retain and compose all license members instead of keeping only the first value.
    • License references are consistently restored when reading SPDX documents.
    • Python package versions with differing letter case are now treated equivalently.
    • SBOM component PURLs now use consistent canonical resolution.

Closes #410. Phase 2.4.

SPDX 2.3 has no free-text license field: licenseDeclared must hold a valid
expression, NOASSERTION, NONE, or a LicenseRef. Bomly wrote an unrecognized
value verbatim -- "see LICENSE file" landed in licenseDeclared as-is --
producing a document a strict consumer can reject. Each such value now mints a
reference and the original text travels beside it in
hasExtractedLicensingInfos, which is what SPDX defines for this case and,
unlike NOASSERTION, keeps the information: ingest reads the text back.

The quieter half was the mixed-validity fallback. A set of one recognized and
one unrecognized license kept only the first and dropped the rest, which a
comment described as deliberate because composing free text would produce
something that does not parse. A LicenseRef is a valid expression element, so
the set composes whole now and nothing a source declared is lost.

Minting is bomly-sdk/spdxkit's, not this package's. A reference has to be
deterministic, collision-free across components assembled without
coordination, and confined to the characters the SPDX idstring grammar allows;
MintLicenseRef answers all three by hashing the whitespace-normalized text,
and a sanitizer written here would be a second, worse answer to a question the
SDK already settled. What stays local is policy: which values classify how,
where the extracted texts attach, and how ingest maps them back.

Ingest resolves only an atomic reference. A compound expression naming one
among other terms has no single text to become, and substituting free text
into it would produce something that no longer parses. A foreign document's
own reference-to-text pairing is taken as stated rather than re-minted: there
the document is the authority, not our hash.

docs/SBOM.md and ADR-0035 drop the limitation they recorded; the ADR gets a
dated note rather than a rewritten body, since it recorded a decision that was
true when made. The note also redirects its references to internal/licenseexpr,
which #428 deleted.

📝 Walkthrough

Walkthrough

SPDX export now converts unrecognized license text into deterministic LicenseRef-* expressions and preserves the text in extracted licensing information. SPDX ingest restores atomic references. PURL projection and Python version normalization now delegate to updated SDK behavior.

Changes

SPDX and SDK alignment

Layer / File(s) Summary
SPDX LicenseRef emission and round trip
internal/sbom/spdx23.go, go.mod
SPDX export mints LicenseRef-* identifiers, composes mixed license sets, emits extracted text once per document, and resolves atomic references during ingest.
SPDX license behavior validation and documentation
internal/sbom/*test.go, docs/SBOM.md, dev-docs/adr/...
Tests validate deterministic references, deduplication, valid expressions, and round trips. Documentation records the updated SPDX behavior.
SDK projection and version normalization
internal/graphview/graphview.go, internal/sbom/transform.go, internal/engine/consolidation/consolidation_test.go
PURL projection delegates to sdk.NodePURL. Consolidation tests cover SDK PEP 440 version canonicalization for Python releases.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to ef7a8

Regenerate and commit any documentation updated by the SDK catalog/support data before merging, so published generated references remain aligned with the pinned SDK.

Legend: ✅ resolved · ❌ failing · ⚠️ warning

v0.9.2 closes both SDK issues this branch's predecessors filed, so the
workarounds they left behind can go.

sdk#43 landed as NodePURL. The projection existed twice here and deliberately
so -- internal/graphview for the renderers and internal/sbom for the codec,
because a codec importing the CLI's output layer inverts the layering -- with
both commented as converging on the accessor once it shipped. It shipped;
both delegate; the question every surface asks of a node has one answer now.
graphview keeps ChildrenAmong and TopLevelParentIDs, which are CLI policy
rather than model semantics.

sdk#39 landed as PEP 440 canonicalization before minting, so two spellings of
one PyPI release fold again. TestPythonVersionCaseIsNotFoldedYet existed to
make that gap visible rather than silent, and its failure message said to fold
the case back into TestEquivalentPythonSpellingsFoldOnInsertion and delete it
once a normalizer arrived. Done exactly that: the fold test carries the
"1.0.0RC1" spelling again.

No golden drift. The fixtures' PyPI versions are already canonical -- pip,
poetry and uv all write normalized versions -- so the change reaches only the
hand-written requirements case it was filed for.
