Q&A Mitigation Review: Fully Alleviated

Issue #15: Re-Entrant Bond Purchase Flow

The code was adjusted per the issue's recommendation, ensuring it conforms to the Checks-Effects-Interactions (CEI) pattern and no longer permits the described attack to occur. The _updateMinCoupon and burn calls can be relocated outside the if-else clause to optimize the codebase as an additional step.

Issue #23: KUMAFeeCollector may emit wrong FeeReleased event

The _release of tokens now occurs solely when there is a non-zero amount of _payees in the contract, alleviating this exhibit. A test case was also included to validate the behaviour of a release with no payees.

Q&A #7: Partially Alleviated

L-01: Remediated
