v0.28.0 shipped a merged SPDX export that the official SPDX validator rejects (#493). The check that found it ran after publication, so it could only report on a release that was already public. The same job had also been failing on its weekly schedule since 14 September; a failed scheduled run notifies no one.

This PR moves the check to where a failure is still cheap, and pins the SDK release that fixes the export.

Why it was in the wrong place

Nothing about the check needs a published release. It needs a built binary. I placed it post-release on the reasoning that it should test what users download — but the published archive is built from the same commit, and its files are verified separately.

What changes

  • Release prerequisites stage. The stage now calls the check, built from the commit about to be tagged. A document a validator rejects stops Auto Version from tagging.
  • Pull requests. It runs on PRs that touch what decides SBOM output: go.mod/go.sum (the SDK owns the codec), the SBOM detector, internal/cli, internal/output, the fixtures, and the check itself.
  • Removed: the post-release copy, the weekly schedule, and the code path that downloaded a released binary.
  • Catalog: sbom-interoperability moves from post-release to prerequisites.
  • Docs: the developer guide and AGENTS.md now state the rule this got wrong — a check belongs in the earliest stage that has what it needs.
  • SDK pin: bomly-sdk v0.14.6 → v0.14.7 (fix(sbom): a source document's checksum is SHA-1, as SPDX requires bomly-sdk#108), which records a source document's checksum as SHA-1 and has the SPDX exporter refuse any other algorithm in externalDocumentRefs.
  • Goldens: the four SBOM smoke goldens, regenerated by Update Smoke Goldens on this branch (test: update smoke golden files #496). Eight lines: the scan record of an ingested SBOM reports the document checksum as sha1 where it reported sha256. The new values equal shasum -a 1 of the two fixtures.

The check proved itself on this PR

Commit SDK "Validate generated SBOMs"
before the pin bump v0.14.6 ❌ validator java failed with exit 1
after the pin bump v0.14.7 ✅ 4 generated SBOM documents passed spdx-tools-java 2.0.7 and cyclonedx-cli 0.32.0, and 1 document check held

So the new pull-request trigger catches the defect, and the SDK release fixes it.

Verified

Not yet exercised: the check running inside the prerequisites stage, which happens on the next Auto Version run.

One cost to know about: the prerequisites stage gains a job that downloads the validators, so a network failure there can hold up a tag until it is re-run.

User-visible change

For an ingested SBOM, bomly scan --format json reports the source document's checksum with "algorithm": "sha1" instead of "sha256". Merged CycloneDX exports carry SHA-1 on their source links for the same reason. Both are conforming; SPDX 2.3 permits only SHA1 in that position.

Summary by CodeRabbit

  • New Features

    • SBOM interoperability checks now run on pull requests that affect SBOM generation and during release prerequisites, before tagging.
    • Checks validate SBOMs produced by a build of the code being assessed.
  • Documentation

    • Updated release guidance to place SBOM checks among prerequisites and clarify when checks run.

…a release

v0.28.0 shipped a merged SPDX export that the official SPDX validator rejects.
The check that found it ran after publication, so it could only report on a
release that was already public. The same job had also been failing on its
weekly schedule for three weeks, and a failed scheduled run notifies no one.

Nothing about the check needs a published release; it needs a built binary.
It was placed after publication on the reasoning that it should test what
users download, but the published archive is built from the same commit and
its files are verified separately. So it moves to where a failure is still
cheap:

- The release prerequisites stage calls it, built from the commit about to be
  tagged. A document a validator rejects now stops Auto Version from tagging.
- It runs on pull requests that touch what decides SBOM output: the pinned
  SDK, which owns the codec, the SBOM detector, the command and output code,
  the fixtures, and the check itself. That is the earliest point, and it is
  where a change of SDK version would have been caught.

The post-release copy and the weekly schedule are removed, and with them the
path that downloaded a released binary. A check nobody is told about is not a
check, and running the same validators again after publication adds nothing
the earlier run did not establish.

The developer guide and AGENTS.md now state the rule this got wrong: a check
belongs in the earliest stage that has what it needs.

This pull request's own run of the check is expected to fail until the SDK
release that fixes the export is pinned here; that bump is added to this
branch when the tag exists.

📝 Walkthrough

Walkthrough

SBOM interoperability now runs on qualifying pull requests and during release prerequisites before tagging. The workflow builds Bomly from the checked ref. Release assessment wiring and documentation reflect the new stage.

Changes

SBOM assurance

Layer / File(s) Summary
Workflow execution and prerequisite check
.github/workflows/sbom-interoperability.yml, .github/workflows/assurance-prerequisites.yml, go.mod, dev-docs/CI.md, test/assurance/SBOM_INTEROPERABILITY.md, docs/ASSURANCE.md
The workflow runs for listed SBOM-related pull-request changes and as a prerequisite check. It builds Bomly from the checked ref, records the supplied assurance tag, and removes the scheduled and released-binary validation paths. The SDK dependency version changes to v0.14.7.
Release-stage assessment and guidance
.github/workflows/assurance-assessment.yml, AGENTS.md, dev-docs/RELEASE_ASSURANCE.md, dev-docs/RELEASE_CHECKLIST.md, docs/assurance/catalog.json
SBOM interoperability moves from post-release assessment to prerequisites. The released-binary report no longer waits for a separate SBOM job. The guidance and catalog describe the updated stage and validation scope.

Before / after behavior

  • observed — Modified behavior in AGENTS.md: The stage lists move SBOM interoperability from post-release to prerequisites. A new rule says checks that need only a built binary belong in prerequisites, and cites the invalid merged SPDX export shipped in v0.28.0 after SBOM interoperability ran post-release.
  • observed — Modified behavior in dev-docs/CI.md: The documented trigger for SBOM interoperability assurance changes from a weekly schedule to pull requests touching SBOM output; dispatch and workflow_call remain.
  • observed — Modified behavior in dev-docs/RELEASE_ASSURANCE.md: The prerequisites workflow list adds sbom-interoperability.yml; the post-release list removes it. The stage-pass rule remains unchanged.
  • observed — Modified behavior in dev-docs/RELEASE_ASSURANCE.md: Adds guidance to place checks in the earliest stage that provides their inputs, distinguishing build-only, draft-release-file, and post-publication requirements. It also describes the SBOM check’s former post-release placement and its new prerequisites and SBOM-output pull-request coverage.

… SHA1

v0.14.7 records a source document's checksum as SHA-1 and has the SPDX
exporter refuse any other algorithm in externalDocumentRefs (bomly-sdk#108).
That is the fix for the merged SPDX export the official validator rejected in
v0.28.0, and the reason this branch's own "Validate generated SBOMs" check was
failing.

Built against the new pin, a document merged from two sources passes the
official validator (spdx/tools-java 2.0.7): "This SPDX Document is valid."

The scan record of an ingested SBOM now reports the document checksum as sha1
where it reported sha256, so the SBOM smoke goldens change; they are
regenerated separately by Update Smoke Goldens.

Update Smoke Goldens, run on this branch, regenerated the four SBOM goldens
for bomly-sdk v0.14.7. The only change is the document checksum the scan
record reports for an ingested SBOM: sha1 where it was sha256, with the
matching values. Eight lines in four files.

…fter publication

The release checklist still listed SBOM validation among the post-release
assessment's steps. That check moved to the prerequisites stage; the
assessment only scans an SBOM input with the released binary.
