The contract inherits renounceOwnership() while critical operations (pause, upgrade, fee, oracle updates) are onlyOwner. Renouncing sets owner to zero and permanently disables those operations — no one can ever respond to an incident.
// owner calls renounceOwnership() (by mistake or after 'decentralising') // pause()/setOracle() are now unreachable forever -> the protocol cannot // be defended during the next exploit.
// disable renounce, or move critical ops behind a non-renounceable role
function renounceOwnership() public override onlyOwner { revert("disabled"); }
