Lumina

LuminaAI is a verifiable light bridge for air-gapped machines. It moves work orders into isolated systems using only a screen and a camera, with no network, radio or USB. Water plants, power stations and factories keep control systems offline, but work orders still have to reach them. That often means USB sticks, a known attack path, or retyping by hand. On the connected side, Muse Spark Open distills a 45-day, 54.9 KB shift log into a 1.7 KB schema-checked work order, and Muse Glimmer 30B red-teams it against the source log. The sender then loops fountain-coded 8-color frames. The receiver can start late or miss frames and still rebuild the file, then verifies it with SHA-256. An on-device policy gate checks the order offline and fails closed: a tampered order is rejected, and a clean one stays on hold for further verification. The plant can sign its decision and beam it back over light. Measured on a tablet in airplane mode: 9.9 KB, 12/12 blocks, SHA-256 verified in 24.0 s, with the screen blocked mid-transfer. The project includes our own LT fountain codec, zero-dependency homography and 66 passing tests.
