AIOil Security Shield — Scan Verification

High — Fee calculation relies on user-provided trade_value_lamports without verification. In `execute_swap_with_fee`, the fee amount is computed from `trade_value_lamports`, which is entirely controlled by the caller. The program has no oracle or cross-instruction verification to confirm the actual swap value. An attacker can supply a small or zero `trade_value_lamports` to pay little or no fee while executing a much larger swap in the same transaction.
