# DisputeKitClassic

> DisputeKitClassic reference: proportional PNK juror drawing, plurality voting, commit-reveal, appeal funding, and equal-split juror incentives.

Default dispute kit with proportional PNK drawing, plurality voting (optional commit-reveal), and equal-split incentives. Supported by all courts as fallback.

## Juror Methods

### `castCommit(uint256 _coreDisputeID, uint256[] _voteIDs, bytes32 _commit)`

Submit vote commitment during commit period (hidden vote courts only).

### `castVote(uint256 _coreDisputeID, uint256[] _voteIDs, uint256 _choice, uint256 _salt, string _justification)`

Cast or reveal a vote. For hidden-vote courts, choice and salt must match commitment.

## Appeal Methods

### `fundAppeal(uint256 _coreDisputeID, uint256 _choice) payable`

Fund an appeal. Winners pay 1× cost, losers pay 2×. Losers have half the funding period. Appeal proceeds when two choices are funded.

### `withdrawFeesAndRewards(uint256 _coreDisputeID, address _beneficiary, uint256 _coreRoundID, uint256 _choice) → uint256`

Withdraw appeal fees and rewards post-resolution.
