An agent binds an enclave key to local camera/mic and answers randomized latency-bound multimodal challenges over days: violet color calibration, timber-grain texture, and fable continuation. Admission needs a contiguous uptime chain. Sybils must provide separate sensors, hardware, and concurrent real-time responses; replay or cloned answers fail timing/ambient checks.
