  - src/denckring_en_data/data/nouns.txt and data/glosses.txt.gz are derived from
    the Open English WordNet 2024 (oewn:2024), licensed CC BY 4.0 and reproduced in
    LICENSE-WORDNET. Both files are modifications: nouns.txt is a filtered list of
    single-word noun lemmas and glosses.txt.gz a compressed lemma-to-definitions
    index, neither in OEWN's own format. scripts/build_lexicon.py is the derivation.

  - src/denckring_en_data/data/graded_words.txt.gz is derived from SCOWL
    2020.12.07, the collective work Copyright 2000-2018 Kevin Atkinson, under the
    terms reproduced in LICENSE-SCOWL. That file is SCOWL's whole Copyright file
    rather than an excerpt of the parts this build draws on, because Atkinson's
    permission notice asks that both the copyright notice and the permission
    notice appear in supporting documentation, and because a licence excerpted to
    the sources drawn on today would need re-excerpting the next time the size
    cap moves. UKACD, whose terms require its notice be reproduced verbatim
    wherever it is redistributed, enters SCOWL at the 80 level and so is not
    redistributed here at all.
    graded_words.txt.gz is a modification: SCOWL's `english-words` and
    `american-words` lists at sizes 10 through 60, reduced to one `word<TAB>size`
    line per word and in none of SCOWL's own formats.
    scripts/build_graded_words.py is the derivation.
