How the best node is chosen Candidates: all cached known nodes + gossip peers from the connected node. Re-probed every 20 s.
  1. Caught-up — within 3 blocks of the network tip; lagging nodes rank below all caught-up ones regardless of speed
  2. Session reliability — probe success rate since page load; a node that has flapped sinks even if currently up
  3. Latency — EWMA round-trip time breaks ties within equally-reliable nodes
