Vulnerability details
Impact
TroveManagerRedemptions does not inherit contracts/Interfaces/ITroveManagerRedemptions.sol but should. Note that TroveManager.sol does inherit ITroveManager. Decoupling an interface from its implementation can lead to code drift and incomplete or incorrect interfaces/implementations.
