-       the gossiper_orphan_remover_fiber on each node before it enters its polling loop,

-    3. Wait until the 4th node's gossip state has fully propagated to all 3 running peers,
-       then trigger its crash via the injection. At this point all peers see it as an orphan:
-       present in gossip but absent from the group0 topology.
-    4. Assert the orphan is visible in gossip (live or down) on the surviving nodes.
-    5. Unblock the gossiper_orphan_remover_fiber on all 3 nodes (via message_injection) and
