 | `relay.announceRounds` | `announce_rounds_total` | Announcement rounds: our new heads to the neighbours after applying their changes (partial mesh only). |
 | `relay.pulls` | `pulls_total` | Pulls of changes we lacked from a neighbour that announced them. |
 | `relay.pullsQueued` | `pulls_queued_total` | Announcements of heads we lacked that waited for the pull in progress. Many compared with `pulls`: changes arrive from several sides at once. |
+| `relay.grafts` | `grafts_total` | Links made eager: a pull brought changes over them, which from then on the neighbour sends as it applies them ([`peers.md`](peers.md)). |
+| `relay.prunes` | `prunes_total` | Links made lazy again: changes came over them that another path had brought first. Grafts and prunes growing together, long after start: links keep switching, as when writers in different places take turns. |
+| `relay.eagerForwards` | `eager_forwards_total` | Changes forwarded over eager links: a sync message per neighbour, instead of an announcement and a pull. |
 | `relay.blobRequestsDropped` | `blob_requests_dropped_total` | Blob requests not answered because too many were being answered; the requester asks again or asks another peer. Also logged as a warning, at most once a minute with the count. |
