“Keep oldest” — whichever partition contains the oldest cluster member survives; the other side is downed. “Oldest” is the lowest address when addresses are compared lexicographically — consistent with the leader election in this project.
Which means the name promises something it does not deliver, and it is worth being blunt about it because an operator picks this strategy for its tiebreak: no join sequence travels in the gossip payload, so a member that joined a minute ago outranks one that has been up for a week whenever its address sorts lower. Choose it for a deterministic, agreed tiebreak and pin the address of the node that should survive — not in the expectation that a long-running coordinator wins (#525).
