Vulnerability details

Impact

In Auction.sol, the state variable bondTimestamp should be called something like bondBlocknumber since it saves the block.number and not timestamp. It's possible that this may lead to issues if in the future the code is upgraded/forked and some new developers don't pay attention to the correct meaning of the variables.
