maker-documented interaction and software surface

The project describes passive observation of nearby broadcast RF evidence and a USB-C Android companion for live views, display controls, and diagnostics. It does not establish detection accuracy, identification certainty, legal authority, range, data retention, user consent, secure transport, a cloud-free operation in every mode, or a safe field-use procedure.

Friend or Foe v0.67.18: Nearby aircraft and stable Bluetooth lists

Primary maker-published post-event Android companion release. It names nearby-aircraft sorting, a 15-mile valid-distance gate for helicopter and ADS-B-drone alerts, refreshed phone location handling, and stable Bluetooth/Privacy result ordering. The publisher reports automated and emulator checks, while explicitly retaining the need for physical-phone Bluetooth and field-location testing; it does not establish physical badge compatibility, RF/detection accuracy, location accuracy, privacy/security outcomes, or field safety.
