Coherence Protocol | 66 followers on LinkedIn. Agentic AI infrastructure for human coherence. | Coherence Protocol is building the trust infrastructure for human-AI systems. AI today has guardrails for models — but nothing for the people in the loop. 68% of failures in healthcare, aviation, and finance trace back to human signal drift, not system error. Our platform fuses biometric signals (HRV, GSR), linguistic patterns, and behavioral context into real-time coherence scoring.
