The highest-priority issue is Review calldata parameter width, with risk score 17/100 based on severity-weighted findings. The function proofHashAt uses a uint256 parameter which may be optimized for gas usage. Review the recommended fixes and run regression tests before deployment. External imports could not be resolved (@oz/contracts/token/ERC20/ERC20.sol); static analysis ran in reduced mode, so Slither/import-dependent checks were skipped while Archon's deterministic rules still ran."
