Security Model
- Cryptoeconomic Security: Jurors stake PNK as collateral
- Random Selection: Weighted random draws prevent manipulation
- Incentive Alignment: Coherent voters earn, incoherent voters lose stake
- Appeal System: Multiple review rounds with increasing juror counts
- Emergency Controls: Guardian can pause, Governor can unpause
