The answers to your questions are exactly the same as if you happen
to run monotone on a host with flaky RAM, or if you suffer a perfectly
normal random bit-flip in a CPU register, or in RAM, or on your bus,
or on your disk, or in the cable leading to it, or on the TCP/IP
connection you're syncing from. Each of these is overwhelmingly more
likely than a hash collision. Do you have plans for such an event?
If not, then you'd better prepare for all that stuff, first. If so,
then you're also prepared for a hash collision.
Actually, I hope that MT is proof against bad packets delivered anyway.
They happen distressingly often.
