Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
The entry remains source-backed and image-free rather than copying site media or attendee diagrams.
Evidence
First-hand attendee toolkit that drives the badge's built-in serial console over its USB Virtual COM Port, handling prompt sync, the one-second settle window, and CR-only line endings, and compiling animations to the badge's LED bytecode.
Official conference site anchoring the August 20-21, 2026 GOELRO Moscow edition and its 2026 recap of roughly 3000 participants and 130+ speakers; the site does not mention the badge.
Format reference documenting the LED bytecode that mirrors the official led_instr.h macros distributed with the badge docs, verified byte-for-byte on real 2026 hardware, including RGB/HSV opcodes and frame-tick timing.
Source trail
Primary official source for the international practical-cybersecurity conference, its August 20-21, 2026 GOELRO Moscow dates, and the 2026 recap figures; no badge statement appears on the site.
Primary artifact source for the STM32 badge board, its USB Virtual COM Port console with led, echo, and mini-game commands, four LEDs, and the official led_instr.h-derived bytecode format.
