Returning a rook restores a forfeited castling right · case 03

Returning a rook restores a forfeited castling right.

Member previewVariant 3 · 3 implementations · 7 checks per implementation

Case contract

Given initial right and event strings rook_move, rook_return, rook_capture, king_move, king_return, other, return whether this side retains castling rights; no board attack/path checks are modeled.

Why this case matters

A deterministic game-rule model isolates this rule interaction for regression testing.

One recorded failure
