# scrabble-dictionary build helpers.
#
# `make dawg` (re)builds the dictionary DAWGs under dawg/ from their word lists, using the
# published scrabble-solver dictdawg/wordlist builders (pinned in go.mod), so the on-disk
# format and letter indexing match the running backend exactly (no index drift):
#   en_sowpods.dawg  — English SOWPODS (Latin alphabet)
#   ru_scrabble.dawg — Russian Scrabble nouns (Cyrillic, 33 letters)
#   ru_erudit.dawg   — Эрудит (the same list with Ё→Е folded and de-duped)
#
# The CI workflow packages dawg/*.dawg into a release artifact on a vX.Y.Z tag.
