A Go library that returns every legal play ranked by score and scores or validates plays, using the Appel-Jacobson DAWG algorithm over github.com/iliadenisov/dafsa v1.1.0. - DAWG move generation (across / down / both), full tournament scoring with a per-tile breakdown; public Solver: GenerateMoves (ranked), ScorePlay, ValidatePlay. - Rulesets: English Scrabble, Russian Scrabble, Эрудит (parameterizable Ruleset). - cmd/builddict (build the DAWG from the dictionaries submodule), cmd/stress (self-play benchmark), selfplay engine; brute-force test oracle. - A GADDAG was implemented, benchmarked and removed (the DAWG was smaller and faster for a scoring solver); see RESULTS.md and ALGORITHM.md.
