Asterion -- Walker-Daye Epistemic Governance Engine v3.1
Built by Todaye AI LLC | Holli Daye, Founder & Chief of Giving
What Asterion Does
Asterion is a real-time epistemic governance engine. It evaluates claims against evidence using CERN-grade 5-sigma statistical thresholds, wraps results in conformal prediction bounds, runs them through a 16-layer self-healing governance spine, and records everything in a tamper-evident cryptographic audit chain.
Core Architecture
- Sigma Scorer -- Scores claims against evidence using 5-sigma statistical thresholds adapted from CERN particle physics.
- Conformal Predictor -- Generates calibrated prediction intervals with coverage guarantees. Auto-calibrates on 200 data points.
- VetoGate -- 5 mandatory checks (sigma threshold, conformal coverage, evidence minimum, governance clearance, audit integrity). Binary PASS or VETO. No override.
- 16-Layer Self-Healing Spine -- Each layer monitors a governance domain (evidence integrity, bias detection, temporal coherence, adversarial robustness, etc.). Layers self-heal when drift is detected.
- Cryptographic Audit Chain -- SHA-256 linked blocks with Merkle tree verification. Every evaluation is permanently recorded.
