Fix gossip validation not detecting UUID mismatch on success#17
Merged
Conversation
validateGossipSystems was ignoring the responding system's UUID after a successful ping. If a different system now lives at an address (e.g., old node replaced by new one), the stale gossip entry was incorrectly marked as "verified" instead of being removed. Now properly checks respSystem.ID != sys.ID and removes stale entries.
