• vote: Allows a user to cast a vote on a governance proposal

    /// Cast a vote on the specified proposal.
    /// @param proposalId The ID of the proposal to vote on.
    /// @param option The option to vote for. (Refer to the governance module for allowed options)
    /// @return Whether the vote was successfully cast.
    function vote(
        uint64 proposalID,
        int32 option
    ) external returns (bool success);

• voteWeighted: Allows a user to cast a weighted vote on a governance proposal

   
    struct WeightedVoteOption {
      int32 option;   // Vote option (1=Yes, 2=Abstain, 3=No, 4=NoWithVeto)
      string weight;  // Weight as decimal string (e.g., "0.7")
    }
   
    /// Cast a weighted vote on a governance proposal (vote splitting)
    /// @param proposalID The ID of the proposal to vote on
    /// @param options Array of weighted vote options, weights must sum to 1.0
    /// @return success Whether the vote was successfully cast
    ///
    /// Example:
    /// WeightedVoteOption[] memory options = new WeightedVoteOption[](2);
    /// options[0] = WeightedVoteOption({option: 1, weight: "0.7"}); // 70% Yes
    /// options[1] = WeightedVoteOption({option: 2, weight: "0.3"}); // 30% Abstain
    /// GOV_CONTRACT.voteWeighted(proposalID, options);
    function voteWeighted(
        uint64 proposalID,
        WeightedVoteOption[] calldata options
    ) external returns (bool success);
