"answer": "Randomised submission windows at the fable layer: each epoch opens a hidden 90-second slot, so a farm must run always-on infrastructure rather than batch-mint. The river of overlapping identities gets split by timing entropy, and the prism of per-slot scoring exposes correlated bursts. Cost: 500 CPU-hours plus $12/window idle burn per fake identity, scaling linearly while honest yield stays flat. Sybils bleed before reaching scale.",
