LICENSE.md already splits Apache-2.0 (code) and CC BY 4.0 (research materials), but machine-readable metadata did not say so: GitHub reports NOASSERTION and CITATION.cff/codemeta.json had no license. - CITATION.cff: license list [Apache-2.0, CC-BY-4.0] - codemeta.json: SPDX license URLs - .zenodo.json: explicit Zenodo metadata (creator + ORCID, license, dual-license note) so the next release archives with correct rights Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01HgE4VrHTz2uD4ChXpzMX3L
Zenodo reads .zenodo.json instead of CITATION.cff when both exist, so a title, keyword, author, or license change made in only one file would be archived stale. The new CI check compares CITATION.cff against .zenodo.json (title, keywords, creators, license) and codemeta.json (version, DOI, licenses, author ORCIDs).

Why
LICENSE.mdalready splits licensing (Apache-2.0 for code, CC BY 4.0 for research materials), but the machine-readable metadata didn't say so:NOASSERTION(its detector can't parse a pointer file to two licenses)CITATION.cffandcodemeta.jsonhad nolicensefield.zenodo.json, so Zenodo infers rights on its own at release timeChanges
CITATION.cff:license: [Apache-2.0, CC-BY-4.0](validated against the CFF 1.2.0 schema)codemeta.json: SPDX license URLs.zenodo.json(new): creator + ORCID, title, description, keywords, archive licensecc-by-4.0, and a note explaining the dual licensescripts/check_metadata_sync.py(new, runs in CI): fails ifCITATION.cffdisagrees with.zenodo.json(title, keywords, creators, license) or withcodemeta.json(version, DOI, licenses, author ORCIDs). Zenodo reads.zenodo.jsoninstead ofCITATION.cff, so a field changed in only one file would otherwise be archived stale.PyYAML==6.0.2and runs the new checkNotes for review
.zenodo.jsontakes one license id.cc-by-4.0was chosen because the research materials are the primary output. Apache-2.0 for the code is stated innotesand inLICENSE.mdinside the archive. After the next release, Apache-2.0 can be added as a second license in the Zenodo record editor.SHA256SUMSis unaffected. It checks the tagged release, notmain.NOASSERTION. That's the correct outcome for a dual license.Tested locally: the sync check passes on this tree and fails as expected when the title or version diverges. Link check, publication-safety scan, experiment 002 validation, reproducibility validation, and unit tests also pass.
