What it does

An in-process simulated physical-radio broadcast medium (BLE/LoRa/WiFi Direct) for testing transports that assume one — a transmitted frame reaches every registered node in range, exactly like real radio.

Open mesh by default (everyone reaches everyone); setReachable()/ setFullMesh() impose a partial topology modeling range limits or obstructions, openMesh() lifts it again.

createDtnBroadcastMedium(ttlMs) adds delay-tolerant store-and-forward: every broadcast is buffered too, and bringIntoRange(a, b) flushes still-live buffered frames to both — simulating two devices moving close enough for contact after being apart. Since a real payload is end-to-end encrypted before it reaches this layer, an intermediate carrier forwards blobs it can't decrypt — mirroring how real LoRa/BLE DTN networks work.
