Recurring patterns

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

Reentrancy: The protocol historically failed to update debt states and burn debt tokens before initiating external ERC20 transfers during repayments, exposing the lending pool to state manipulation.

Auth Bypass: Unauthorized execution paths and improper routing of approval checks in ShareDebtToken allowed attackers to bypass spend/receive allowances and mint or transfer debt tokens without appropriate authorization.

Logic Error: Critical failure to execute price oracle beforeQuote updates prior to checking solvency and maximum LTV allowed transfers or withdrawals to proceed against stale or manipulated oracle states.
