For contacts without GPS, estimate their position by: 1. Finding the first-hop repeater from their routing path 2. Estimating distance from RSSI using log-distance path loss model 3. Placing them at a deterministic offset from the repeater Uses LoRa outdoor path loss exponent (n=3.0) with reference RSSI -30dBm at 1m. Distance clamped to 10m-50km range. Bearing derived from contact public key hash for stable positioning.
