Remove the standalone solver wrapper module. Its thin shaping — build a solve-budgeted Session, run card_game::Session::solve(), extract the first useful move — moves onto the domain type in solitaire_core as GameState::solve_first_move() / GameState::solve_fresh_deal(), with the budget consts and the SolveOutcome alias re-exported from solitaire_core. Solving is deterministic, IO-free game logic, so core (which already owns GameState and exposes session().solve()) is its correct home; solitaire_data is the persistence/sync layer and never should have owned it. Consumers now call the core API directly: - engine: pending_hint (solve_first_move), game_plugin + play_by_seed_plugin (solve_fresh_deal), input_plugin (budget consts) - assetgen: gen_seeds + gen_difficulty_seeds (solve_fresh_deal) The solver tests move to solitaire_core. cargo test --workspace and clippy --workspace --all-targets -- -D warnings both green. Resolves the "delete the solver" directive — card_game provides the solver. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
