882e176b34wrap-board previously contributed a single one-square hop when the rook/queen was already on an edge file, which is essentially a no-op for 99% of positions. Rewrote the hook to implement an actual cylindrical topology: sliders walk past the a/h seam and continue along the rank on the opposite side, stopping at the first ally (no destination) or enemy (capture). Preserves the rook-warp incompatibility since the two presets have different "when does the wrap apply" preconditions. Check indicator: GameView looked for an `InCheck` boolean fact that doesn`t exist in the session — check status is a derived predicate (isInCheck), not a stored fact. Exported isInCheck from the package public API, wired GameView to query it per render, added a pulsing red "Check!" banner in the header, and fixed the useChessEngine audio path which had the same stale-fact bug (was never playing the check sound). Tests: 6 new wrap-board tests covering empty-rank slides, partial blocks, queen slides, and the no-op case for non-sliders. Total 849 tests pass (+6). |
