Control Is Not Optional.
Every action request is evaluated against immutable policy, authority class, and risk tier before execution.
Runtime Enforcement
Behavioral constraints executed in code — not policy documents. Every model action passes through constitutional gates before it can affect state.
Fail-Closed Architecture
No silent drift. No permission leakage. No uncontrolled recursion. When in doubt, the system denies. Always.
Cryptographic Evidence Chain
Every consequential action is logged, hashed, and reproducible. Append-only. Tamper-evident. Auditor-readable.
AI models do not execute directly.
They pass through constitutional gates.
Hard Facts.
No adjectives. No slides. No simulation environments.
Sovereign Mode.
For regulated, critical, or state-level environments.
Platform Surfaces.
Each surface is verifiable. Each surface is cryptographically bound.
Enterprise Runtime Licensing.
Ethraeon operates as infrastructure. Enterprise runtime subscription. Sovereign deployment contracts. Governance integration fees. The constitutional layer becomes mandatory as autonomy scales.
