Needs to be implemented during the check in net_processing::ProcessMessage(): NetMsgType::HEADERS, BLOCK, CMPCTBLOCK, INV

Probably more appropriate to do it during the selection of the most work chain.

Sorry, wrong train of thought. You're right, the tie-breaking portion would be implemented during the selection of most work, but I do need to record when the block is first seen in the above cases.
