Evidence index
Primary docs, public wikis, repositories, talks, press writeups, and first-hand notes used to support badge pages.
Primary first-person commit note for local boot-smoke/diagnostics claims and remaining over-air infrared wiring work. The note is retained as a limited publisher claim rather than independent hardware verification, a production report, or an operational endorsement.
Commit-pinned public source tree for the V2 sketch and support files. The source header calls it DEF CON 34 Agency badge V2 and says handshake, infrared, and logging are not wired up yet. It does not prove current source compiles, maps to a specific board, has been installed on a physical unit, is safe to modify, or is a complete firmware release.
Primary public repository for the DEF CON 34 'Agency' SAO badge firmware / Waveshare RP2040-Zero description. It supports a source-project and event-label claim only; it does not identify a real-world person, prove final physical hardware, establish a released build, license, event authorization, distribution, access function, or reusable image permission.
First-party historical tutorial source for the distinct Tricorder SAO, linked from the product documentation. It establishes tutorial context only, not current Original Series Tricorder badge hardware, sensor function, sale completion, or reusable-video-frame permission.
Public historical user documentation that describes separate rechargeable-battery and badge-powered Tricorder SAO forms, USB-C, LEDs, and lanyard use. It is not a current badge specification, circuit/firmware archive, safety guide, or revision map for the $125 Original Series Tricorder badge.
Public same-maker repository for a separately named historical Tricorder SAO. Its current root supports maker/product-lineage context only and has no explicit root licence; it does not prove that current Original Series Tricorder badge units share the repository's design, electronics, behavior, price, or distribution.
Primary same-maker seller source for a distinct $30 Tricorder SAO. It corroborates the historical public product lineage but not current-event badge parity, sensor details, stock, price, sale completion, third-party permissions, or image reuse rights.
Primary first-party marketplace source for the DEF CON 34 association, live August 4 availability snapshot, product naming, cedar construction, standard-SAO compatibility claim, standalone animations, host-control framing, GPIO modes, and drop labels. It does not establish final manufacture, delivery, host safety, universal compatibility, DEF CON organizer status, admission, or image reuse permission.
Primary current-event source naming a new Original Series Tricorder badge, its planned Hacker Warehouse on-site acquisition channel, approximately $125 price, 60th-anniversary Star Trek framing, and various-sensors wording. It does not provide a badge photo, product URL, sensor list, hardware/firmware detail, final stock, completed sale, official status, or media rights.

Public third-party firmware source for custom NFC-to-webhook behavior. Its README describes ESP32-S3-WROOM-1, 16 MB flash, ST25R3916 NFC, a six-button D-pad, and an 18-pixel NeoPixel ring; the project tree includes display and no-display builds but no project license metadata or root license file. It is separate from NorthSec's Apache-2.0 source release.
First-person maker announcement saying the author created Ouroboros as a CH32V003 pure-RISC-V-assembler project with a custom UART game. It links the product and explainer and describes buyer-arranged DEF CON pickup intent, but not completed production, transfer, venue authorization, official issuance, admission, or reuse permission for its media.
Secondary first-hand attendee source, published October 12, 2026, confirming that the October 7-9 conference took place and that at least this attendee held a 2026 electronic Eko Badge running a Meshtastic build. It does not give a badge count, the share of Champion tickets fulfilled, or any field issues.
Named live-game host's public announcement of the NaClCON NFC scavenger-hunt and social-networking experiences, without a badge-manufacturing or software-release claim.
