maker-documented hardware platform
The maker describes one badge as an uplink/display XIAO ESP32-S3 and two XIAO ESP32-S3 scanners that share one scanner image but receive BLE-primary and Wi-Fi-primary roles at runtime. It is a source-described architecture, not proof of a universal production revision, board provenance, field reliability, or authorized radio deployment.

maker-published fabrication and mechanical documentation
Primary source for the Gerber/fabrication, component, battery-polarity, button-fit, display-fit, antenna, and 45-unit DEF CON-run statements. It does not establish final unit equality, safe construction, regulatory compliance, or participant allocation.
Badge: Friend or Foe Badge (DEF CON 34 Packet Hacking Village)
maker-published hardware and firmware archive
Public maker archive for the Friend or Foe badge's high-level hardware, firmware, Android, backend, and documentation trail. It establishes a publisher-described independent project, not DEF CON or Packet Hacking Village issuance, event-wide allocation, a security review, or a reusable image grant.

maker-published post-event Android release
The September 16, 2026 release publishes an Android APK and checksum for the companion's nearby-aircraft ordering, 15-mile aircraft-alert distance gate, location-refresh handling, and Bluetooth/Privacy-list stability changes. Its publisher-reported emulator and test results do not establish physical-phone, badge, Bluetooth-radio, location, RF, privacy, security, or field-operation validation.

maker-published project documentation
Primary maker documentation for the three-board ESP32-S3 badge architecture, passive RF-awareness framing, display/Android surface, published version labels, and stated 45-badge DEF CON run cost context. It is not an independent manufacturing, allocation, safety, or performance audit.

official village programme
Primary official programme source for the completed Friend or Foe presentation, its Packet Hacking Village association, and the source-named Will Hatzer / Charles Grow roles. It does not establish badge allocation, recipient handoff, RF performance, or image rights.

official village programme
Primary Packet Hacking Village page for the completed August 7-9, 2026 DEF CON 34 village setting and its scheduled Friend or Foe presentation. It does not say the village or DEF CON issued, sold, funded, or distributed the badge.

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.
