  "summary": "Fixes an ineffective check in `AddrManImpl::AddSingle()` that was intended to prevent duplicate address announcements from increasing an entry's multiplicity in the new table. When an address is stored, its timestamp has a 2-hour penalty subtracted, which caused subsequent identical announcements to appear newer than the stored record unless the penalty is also subtracted during comparison.",
  "problem": "When the same address gossip announcement is received from multiple peers, the node unintentionally increases the address's multiplicity up to 8 because the comparison logic fails to apply the time penalty to incoming announcements.",

Because stored entries have a 2-hour time penalty subtracted, incoming identical announcements compared as newer unless the penalty was applied to the comparison. The fix applies the penalty during the check and adds a unit test. There is currently no review activity on this PR."
