New GET /api/nodes/{pubkey}/hop_analytics?days= returns, for each recent
transmission that passed through this node as a relay, the node's own
0-based index within the packet's resolved path -- the value MeshCore
firmware compares against flood_max/flood_max_advert/flood_max_unscoped
in allowPacketForward (Packet.cpp path_len = header & 63; MyMesh.cpp
getPathHashCount() >= flood_max). Deliberately distinct from the
existing hopDistribution field on /analytics, which measures path
length to whichever observer reported the packet -- a different,
unrelated number, confirmed via the upstream issue's multi-round
firmware-source discussion.
Candidate-finding reuses the same byPathHop-index + resolved_path
confirmation approach as handleNodePaths (routes.go), written fresh
rather than refactored out of that function to avoid any regression
risk in its older, correctness-critical prefix-collision handling
(#929, #1197, #1278, #1352). Only transmissions with a canonical
resolved_path contribute a data point -- no resolved_path means no
reliable hop index, so it's skipped rather than guessed.
Frontend: new "Relay Hop-Count" card on the node analytics page --
histogram (Chart.js) + a hand-drawn boxplot canvas above it sharing the
same x-axis (no Chart.js boxplot plugin is loaded), filterable by chip
matching the firmware knob names (flood default, flood_advert,
flood_unscoped, direct).
