I'll do my best.

I don't believe so but in a corrupted state it is theoretically possible.
If the record pointer is moved past the end of the buffer to the EOF node in
the underlying structure and the code to make sure additional records are
brought from the server (if necessary) is not run then it could happen.

It shouldn't.

I believe that would be the case. A careful look at the source code would
be required.
