Attribution is the point of this licence rather than a formality. Published results
that cite the lattice should also cite its hash, so a reader can tell which version

A note on lineage: some leaves carry a `sourceSystem` field naming where a concept or
a period boundary was verified — BISAC, Colon Classification, the Chinese Library
Classification, Nippon Decimal Classification, Encyclopaedia Britannica, the Princeton
Encyclopedia of Poetry and Poetics, and others. These are citations of consulted
reference works. No coded list, controlled vocabulary, or text was imported from any
of them; the leaf names are ordinary descriptive terms and the selection and
arrangement are original to this artifact.
