Each handler took the latest time per key in a batch and inserted it as a new row's first_seen, so a key updated twice in one batch, seconds apart, was stored first seen at the later time, and the IP lookup could answer with a prefix first_seen after the route's last_seen. The prefix handler now keeps the earliest time of all of the batch's updates for each prefix. The AS, peer and peering handlers keep the earliest and the latest time per key in database.SeenTimes, and GetOrCreateASNBatch, UpdatePeerBatch and RecordPeering store a new row first seen at the earliest and last seen at the latest. A stored row still has only its last_seen set, to the latest. Model: opus-5-5
