UNDERWORDLE WORD-DATA SOURCES

Extract shared.zip and the nine language ZIPs into the same empty directory,
preserving paths. These contain the source inputs, provenance, notices,
selection records and build tools for the ten released languages. Upstream
archives are retained unchanged. SOURCE-MANIFEST.json lists every project file
and its SHA-256 digest. No artwork, player data or account/server code is included.

Licence notices apply to their respective files; this collection does not
relicense the upstream data or unrelated game code. See assets/word-list[-code]-
license.txt, each source directory's PROVENANCE/README/COPYING/LICENCE files,
and scripts/simulation/data/NOTICE.txt for the frequency-table attribution.

To verify the current answer pools (Python 3, in an isolated environment):
  python -m pip install --target .qa/german/python spylls==0.1.7
  python scripts/build-answer-pools.py --check

To rebuild a language's accepted guesses, follow its PROVENANCE.txt and run:
  python scripts/build-<language>-words.py
  python scripts/build-answer-pools.py --write
  python scripts/build-answer-pools.py --check

The shared answer-pool builder must run after a per-language builder: it applies
the current reviewed answer selections. The --check output covers all ten
languages. Optional research/verification scripts retained in source directories
may need additional dependencies documented in those scripts.
