addCuratedPool() is missing a require(isCuratedPool[_pool] == false) check, similar to the one in removeCuratedPool to ensure that the DAO is not trying to curate an already curated pool which indicates a mismatch of assumption/accounting compared to the contract state.
Recommend adding require(isCuratedPool[_pool] == false) before setting isCuratedPool[_pool] = true.
