Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an\n * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer\n * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.\n *\n * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be\n * reused. This mechanism prevents re-execution of each \"step\" but allows the creation of new initialization steps in\n * case an upgrade adds a module that needs to be initialized.\n *\n * For example:\n *\n * [.hljs-theme-light.nopadding]\n * ```\n * contract MyToken is ERC20Upgradeable {\n *     function initialize() initializer public {\n *         __ERC20_init(\"MyToken\", \"MTK\");\n *     }\n * }\n * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {\n *     function initializeV2() reinitializer(2) public {\n *         __ERC20Permit_init(\"MyToken\");\n *     }\n * }\n * ```\n *\n * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as\n * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.\n *\n * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure\n * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.\n *\n * [CAUTION]\n * ====\n * Avoid leaving a contract uninitialized.\n *\n * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation\n * contract, which may impact the proxy.

After each targetTime, it aggregates total bribes and\n///         voting results using subgraph querying, calculates user rewards, and enables reward\n///         claiming through a distributor contract. The contract incorporates features like native\n///         and ERC20 token support for bribes, and admin functions for pool and token management.\n///\n/// @author Cakepie Team\n\ncontract CakepieBribeManager is\n    Initializable,\n    OwnableUpgradeable,\n    ReentrancyGuardUpgradeable,\n    PausableUpgradeable\n{\n    using Math for uint256;\n    using SafeERC20 for IERC20;\n\n    /* ============ Structs ============ */\n\n    struct Pool {\n        bytes32 gaugeHash;\n        address pool;\n        uint256 gaugeType;\n        uint256 chainId;\n        bool isActive;\n    }\n\n    struct Bribe {\n        address token;\n        uint256 amount;\n    }\n\n    struct BribesInPool {\n        address pool;\n        Bribe[] bribe;\n    }\n\n    struct PoolVotes {\n        address bribe;\n        uint256 votes;\n    }\n\n    /* ============ Constants for PCS integration ============ */\n\n    /// @dev 7 * 86400 seconds - all future times are rounded by week\n    uint256 constant WEEK = 604800;\n    /// @dev Add 2 weeks time to calculate actual 2 weeks targetTime\n    uint256 constant TWOWEEK = WEEK * 2;\n\n    /* ============ State Variables ============ */\n\n    address constant NATIVE = address(1);\n    uint256 constant DENOMINATOR = 10000;\n\n    address public voteManager;\n    address payable public distributor;\n    address payable private feeCollector;\n    uint256 public feeRatio;\n    uint256 public maxBribingBatch;\n\n    address[] public pools;\n    mapping(address => Pool) public poolInfo;\n    mapping(address => uint256) public unCollectedFee;\n\n    address[] public allowedTokens;\n    mapping(address => bool) public allowedToken;\n    mapping(bytes32 => Bribe) public bribes; // The index is hashed based on the targetTime, pool and token address\n    mapping(bytes32 => bytes32[]) public bribesInPool; // Mapping pool => bribes.
