Follow-up to #17. 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 (screenshot after the #18 deploy: 9 of 20 rows blank). Query G now takes the current series and, for preimages without one, the last label set seen in the range, one per preimage. Verified against Prometheus: 11 current series, 13 with the 6 h fallback; older rows fill in as the metric's history grows past the range.

grafana: leaderboard author label falls back to the last one seen in the range c10d48da3a

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).
