Build a committed Russian common-noun word list (dictprep/russian/scrabble.txt)
from the RAN orthographic dictionary, for the Эрудит ruleset.
- Stage 1 (Go, dictprep/ruwords): orfo_dict_2025.txt -> all.txt; extracts
headwords, reconstructs "ед." singulars (suppressing plurals), pairs "и" variants.
- Stage 2 (Python brain, dictprep/ru_stage2.py): OpenCorpora (mawo-pymorphy3) +
libmorph + orthographic notes select common nouns (nom. sing.); --trace explains
a word's fate, --dump writes the in-memory buckets.
- libmorph C++ bridge (libmorph_check.cpp); manual_confirm.txt is merged in.
- orfo_dict_2025.txt is the committed pdftotext source of truth.
- See dictprep/README.md for methodology and reproducibility.
