With an administrator-simulated 10001 bps legacy rate and a simulated 1 TIBBIR transfer from the recognized pool, unchecked amount-minus-tax underflows. For a NONZERO recipient address with zero existing balance, the transfer returns true and credits 2^256−100000000000000 smallest units while totalSupply remains unchanged. With 1 TIBBIR already in that recipient, the later checked balance addition instead reverts with Panic(0x11); sender, recipient and tax balances roll back.This is a conditional legacy configuration defect. It requires owner/factory authority to set an excessive rate; it is not current 1% behavior, not an unprivileged exploit, and no actual abuse is evidenced.
