ESP32 CSI relay (csi-relay-routes.json) never matches live traffic: route src port vs ephemeral UDP source

[markt-heximal]

Component: RVF aggregator ESP32 relay · csi-relay-routes.json

Summary

The ESP32 CSI relay never forwards frames because route src is matched against an ip:port that can't match the ESP32s' ephemeral UDP source ports.

Evidence

• Routes are configured as {"src":"<esp32-ip>:5006","dst":[...]}.
• ESP32 nodes actually send CSI from ephemeral source ports → the aggregator's listen port (observed e.g. …:50038 → …:5008, …:52000 → …:5008). The configured :5006 source never matches.
• After pointing a route at a reachable consumer and restarting the aggregator, no relay occurred and no relay/route log lines were emitted.
• A stale/unreachable dst silently no-ops with no warning.

Impact

CSI is ingested on the listen port but never relayed downstream, starving all consumers. Med-High.

Asks

1. Match relay routes by source IP (or by the frame's node-id), not ip:port.
2. Log unmatched frames and unreachable dst targets so misconfig is visible.

Closing: off-topic. This issue references an "RVF aggregator" and csi-relay-routes.json which are not components of this project (wifi-densepose / RuView). Please file against the correct repository.
