Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Access Control: The upgrade function lacked an owner-only restriction, allowing any caller to trigger a contract upgrade and potentially take over the contract.

Reentrancy: View functions like getReserves and getSwapOut could be re-entered during state-changing operations, allowing attackers to manipulate returned values and exploit the contract.

Integer Overflow: Division rounding down in calcReserve could lead to small reserve discrepancies, which over many operations could be exploited for economic gain.
