The original author-provided v4 replication and AEI Python files are included
in this scope at their preserved nested paths. This notice does not modify
the original Zenodo version-1.0.0 licence file. That original notice continues
to apply to its author-provided code in ilr_core/ and research_preview_v4/,
plus reproduce_core_offline.py and verify_package.py, if those files are
redistributed in their original package layout.

Third-party dependencies retain their own licences. This grant does not
relicense OECD, World Bank, Anthropic or other third-party data, source
responses, quotations, logos or material. Data, figures and documentation
are governed separately by LICENSE-DATA.md, subject to its source-rights
reservations and attribution requirements.
