Primary official post-event source: Artwork, Badge, Speakers, and Talks folders dated September 28, 2026, including track slide archives and speaker bios, establish that the September 23-25 edition was held. The drop does not state electronic-badge counts, Type-B allocation, or who received which badge.

Official commemorative magazine whose ROOTCON 20 Badge / Before the Reveal page credits Mr. Blinky Bling with the twentieth-anniversary badge. The PDF was produced on August 15, 2026, before the event, so it is a credit source rather than a distribution record.

Primary technical source, inspected locally from the official binary: ESP32-S3 image header, rc20 app descriptor built September 6, 2026 with ESP-IDF 5.5.5 from PlatformIO environment rc20-human-fw, ROOTCON 20 Badge banner strings, Meshtastic mesh modules, SX1262 radio driver, SSD1315 128x64 display, 4x WS2812B GPIO37, ROOTCON 20 region lock forcing PH_433, NimBLE, libpax counting, and Tetris and Breakout high-score files. String evidence describes the compiled build only; it does not prove every feature was enabled on shipped boards.
