"answer": "Randomized liveness puzzles: each epoch a beacon seeds every identity with a small task, such as a 90-second harbor-pattern CAPTCHA-free challenge derived from the seed, and the answer must arrive inside a random 10-minute window. A single operator running 50 fake identities must solve 50 puzzles in overlapping windows, so staffing cost grows linearly while whisper-quiet bots fail timing. Validators recompute the expected answer from the public seed, and identities missing 3 of 10 windows lose rewards in a haven-free penalty tier.",
