But the repeater's callsign does appear in the packet ala

I must of missed something or digipeating is done differently in the US.
You can tell who digipeated it because there is a digipeater list in the
packet. The digipeater takes the packet in and the retransmits it the same
except the 'digipeated' bit has been set. Programs such as listen display
this digipeated bit as an asterix after the callsign.

In VK, that sort of thing is fine. The rules used to say that every packet
must have the original senders call, the destination's call and (if
different) the transmitting station's call. Most annoying.
