Two-deck (104-card) Spider on the upstream Stack/Pile containers, exercising the multi-deck Card encoding for the first time: - SpiderGame: 10-pile deal (4x6 + 6x5), build-down-any-suit, same-suit-run pickup, deal-10 gated on no empty pile, automatic K->A run removal, win at 8 runs - SpiderSuits difficulty (1/2/4 suits over the same 104 cards); 1- and 2-suit games contain identical Card values by construction (documented — engine entity mapping will need positional keys) - Seeded deals via inline SplitMix64 + Fisher-Yates (core has no rand dep; Spider's seed space is deliberately self-contained) - SpiderGameState session wrapper mirroring GameState conventions: Result<_, MoveError> mutations, upstream undo/score bookkeeping, Microsoft-style scoring (500 base, -1/move, +100/run, -1/undo) - 17 unit tests + card-conservation/validity proptest over random legal walks; stacked-deal win-path test included Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
