468-481: Security and Logic Review for theflushFunction
Security Check on Proof of Humanity: The function first checks if the juror is eligible by calling
_proofOfHumanity. If the juror is eligible, the function exits without taking any action, which is a good security practice to prevent unnecessary or harmful state changes.Loop Over Courts: The function iterates over an array of court IDs. For each court, it checks if the Dispute Kit is supported using
core.isSupported. This is crucial to ensure that the operation is only performed in relevant contexts.Setting Stake to Zero: If the checks pass,
core.setStakeBySortitionModuleis called to set the juror's stake to zero for the given court. This effectively unstakes the juror, which is the intended functionality of this function.Potential Gas Optimization: Consider limiting the length of the
_courtsarray to prevent excessive gas costs due to a large number of iterations.Error Handling: Proper error messages are provided in the require statements, which is good for debugging and user feedback.
Overall, the function appears secure and logically sound, but consider adding a limit to the
_courtsarray size to manage potential gas issues.contracts/src/arbitration/KlerosCoreBase.sol (1)
104-104: Review of New Mapping and Related Changes inKlerosCoreBase.sol
Mapping Declaration: The new mapping
disputeKitIDsis declared to mapIDisputeKittouint256. This is a foundational change that supports the management of multiple dispute kits.Initialization of Mapping: The mapping is initialized in the
_initializefunction with the classic dispute kit. This is a critical setup step ensuring that the system starts with a known state.Addition of New Dispute Kits: The function
addNewDisputeKitadds new entries to thedisputeKitIDsmapping. This function is crucial for the system's extensibility, allowing new dispute kits to be registered and managed.Security and Best Practices: The changes include appropriate checks and error handling. The use of the
onlyByGovernormodifier ensures that only authorized users can make changes, which is important for maintaining the integrity of the system.Overall, the changes are well-implemented and follow best practices for contract development in Solidity.

468-480: LGTM! Consider adding comments for clarity.The
flushfunction is well-implemented and ensures that only ineligible jurors are unstaked from supported courts.For better readability, consider adding comments to explain the purpose of each major step in the function.
