CSTB Trust DePIN Protocol

1. User starts gaze training session in DOJO
2. Camera captures eye movement at 60fps
3. Proprietary classifier maps gaze → AGT tensors (COG/EMO/ENV)
4. Minimum gaze data collected (quality threshold)
5. Edge compute stores tensors in real-time database
6. JOE Agent validates session integrity
7. CSTB program on Solana creates attestation PDA
8. $OPTX minted to user's wallet (60% of reward pool)
9. Attestation hash stored on-chain for future verification

Requirements:
  - Min gaze duration: configurable (governance parameter)
  - Min entropy: configurable (governance parameter)
  - Difficulty target: configurable (governance parameter)
  - AGT constraint: COG + EMO + ENV must normalize to unity
