Live wireless mesh

Four devices.
One route. One real settlement.

Registers 4 relays (a phone, a router, a laptop, another phone), stitches 3 wireless links between them, requests a route from phone-1 to phone-2, opens a session, transfers 50MB, settles via the Settlement Grid. Every step is a real call against /api/air.

Every action above hits the live Air registry, pathfinder, session lifecycle, and Settlement Grid. Phase 1 simulates the bytes (no real radios in the browser yet); Phase 2 wires iOS/Android/router-firmware adapters that drive the same protocol with actual packets.
