Why It Mattered

It adds a clean MIT-licensed open-hardware developer-conference badge to the North American map with full firmware and hardware documentation, while keeping the event photo unpublished because the repository explicitly excludes photos from the MIT license.

Hardware

The repository documents an ESP32-S3 application platform with an OLED display, an LED matrix, infrared transceivers for boop badge-to-badge networking, and the supporting power and input hardware described in the hardware README and BOM. The hardware source is published under the repository's MIT license.

Software & Apps

The MIT-licensed firmware exposes a Doom port, a MicroPython environment, an infrared boop system for badge-to-badge interaction documented in BoopSystem.md, community apps, and a schedule data server. Third-party notices and codeowners are preserved in the repository.

Lore

Replay is Temporal's developer conference, and the 2026 edition ran May 5-7 in San Francisco. The official badge repository is published under the temporal-community GitHub organization with an MIT license covering firmware and hardware source; the repository's photo README explicitly states that event photos are not covered by the MIT license, so the catalogue withholds the image.

Issues & Camp Impact

missing rights-cleared image note

No Temporal Replay 2026 badge image is published because the repository photo README explicitly excludes event photos from the MIT license, leaving no reusable original badge photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes.

The United States record remains source-backed and image-free rather than copying repository photos excluded from the MIT license, screenshots, social media, placeholders, or generated approximations.
