WORDWARD RUSSIAN WORD DATA — MODIFIED DERIVATIVE

The accepted-guess list and curated answer module derive from Alexander I.
Lebedev's Russian spelling data in LibreOffice/dictionaries, pinned at commit
67032ee957631908098a72edf48dc81cac27e369 (ru_RU directory).

The original source files are unchanged and retained in assets/russian-source.
Wordward modifications (2026-10-25): expand conditional suffix rules; exclude
capitalized names, acronyms, punctuation and unsupported letters using original
case; retain native 3–7-letter words; apply explicit Russian case mapping and
Ё→Е board identities; deduplicate; add a small documented current-word supplement;
select an explicit everyday answer deck while preserving selected Ё spellings;
exclude the individually documented obsolete spelling придти in favor of прийти.
See assets/russian-source/PROVENANCE.txt and reviewed-additions-ru.json / reviewed-exclusions-ru.json.

The current-word supplement contains individually reviewed spellings and source
paradigm inflections with factual spelling references; it does not reproduce
external dictionary definitions. No claim of author or publisher endorsement,
native-speaker approval, or exhaustive modern-language coverage is made.

The full original spelling-source notice follows. It must remain with source
and distributed derivatives. This notice is not the separate thesaurus license.
