The exporter emits quantus_author_node_info only for authors in its rolling
block window, which is rebuilt from live blocks after a restart, while the
leaderboard covers the dashboard range. Authors outside the window showed a
blank author cell. Query G now takes the current series and, for preimages
without one, the last label set seen in the range (one per preimage).
