Build & Test (NowChessSystems) TeamCity build finished
Summary - Curried candidateMoves, legalMoves, and applyMove in the RuleSet trait to separate (context) as the world being operated on from the computation parameter - Updated DefaultRules overrides and all internal call sites - Updated all external call sites: GameEngine, PgnParser, PgnExporter, ChessBoardView, and all affected tests Test plan - All existing tests pass (./gradlew build) - No behaviour changes — pure style refactoring, existing test suite is the regression guard Co-authored-by: LQ63 <lkhermann@web.de> Reviewed-on: #18 Reviewed-by: Janis <janis-e@gmx.de> Co-authored-by: Leon Hermann <lq@blackhole.local> Co-committed-by: Leon Hermann <lq@blackhole.local>
