KnowingTaoRebaseBlock.KnowingTaoRebaseBlock_validateTransfer(address,address,uint256) (contracts/Trap/sTaoProtectedBase.sol#26-30) uses a dangerous strict equality:
- sTaoCheckBlock == 0 && _to == Staking && _amount > 0 (contracts/Trap/sTaoProtectedBase.sol#27)
Don't use strict equality to determine if an account has enough Ether or tokens.

vault() should be declared external:
- VaultOwned.vault() (contracts/Utils/Divine.sol#1322-1324)
Use the external attribute for functions never called from the contract.

EnumerableSet.getValues(EnumerableSet.AddressSet).addressArray (contracts/Utils/Divine.sol#338) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

TWAPOracleUpdater._uodateTWAPOracle(address,uint256) (contracts/Utils/Divine.sol#1379-1383) ignores return value by twapOracle.updateTWAP(dexPoolToUpdateFrom_,twapEpochPeriodToUpdate_) (contracts/Utils/Divine.sol#1381)
Ensure that all the return values of the function calls are used.

VaultOwned.setVault(address) (contracts/Utils/Divine.sol#1313-1317) should emit an event for:
- _vault = vault_ (contracts/Utils/Divine.sol#1314)
Emit an event for critical parameter changes.
Additional information: link
VaultOwned.setVault(address).vault_ (contracts/Utils/Divine.sol#1313) lacks a zero-check on :
- _vault = vault_ (contracts/Utils/Divine.sol#1314)
Check that the address is not zero.

Apply the check-effects-interactions pattern.

ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (contracts/Utils/Divine.sol#1217-1238) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,Permit: expired deadline) (contracts/Utils/Divine.sol#1226)
Avoid relying on block.timestamp.
