High-assurance models that never run on someone else's cloud — air-gapped, owner-keyed, and post-quantum by default. Built for institutions where the operating assumption is that the network is contested.
Sovereignty here means physical and cryptographic control, with no exceptions.
The model is deployed on infrastructure the owner physically controls — never as a tenant on a third party's cloud. There is no shared control plane an outside operator could reach.
The model is engineered to run fully disconnected from public networks. Inference and updates can occur inside an isolated enclave with no dependence on external endpoints.
Training and serving run on the nation's own data-center and GPU capacity under its residency rules. The full lifecycle stays inside the sovereign and physical perimeter.
The operator holds both the signing keys and the model weights as controlled assets. Nothing about the model's operation depends on a credential someone else can revoke.
Every artifact in the deployment is signed, chained, and verifiable under post-quantum primitives.
Weights, configuration, and updates are signed under ML-DSA-65 (FIPS 204). The enclave verifies a post-quantum signature before loading a model, rejecting anything unsigned or altered.
Model actions and decisions are written to a hash-chained, tamper-evident ledger. Any modification of the record is detectable, giving investigators a trustworthy account of what the model did.
The lineage of weights, data, and dependencies is recorded and signed end to end. An operator can verify that the model in the enclave is exactly the reviewed artifact, with nothing injected.
The assurance posture assumes an adversary with future cryptographic capability. Signatures and integrity guarantees are chosen to hold against that threat, not just today's.
Constraint and observability are engineered in, so the model never becomes an uncontrolled actor.
The model advises and analyzes; it does not take physical or financial action on its own. Any consequential action is gated behind an authorized human and key-controlled execution.
Inputs, outputs, and decision context are logged to the tamper-evident ledger for after-action review. Operators can reconstruct exactly what the model saw and produced under pressure.
Hard constraints are enforced by deterministic logic outside the model, not by prompt instructions. Critical boundaries do not depend on the model choosing to respect them.
When integrity checks fail or context is missing, the deployment stops rather than proceeding. The default under uncertainty is to halt, not to improvise.
High assurance includes operating when the outside world is unavailable or hostile.
Everything the model needs to run lives inside the enclave — weights, dependencies, and verification keys. A severed external link degrades nothing in the core capability.
Because the owner holds the weights and keys, operation does not hinge on a supplier remaining reachable or solvent. The capability is durable against the vendor disappearing.
Model updates are staged, signed, and applied on the owner's schedule through controlled media. Nothing changes in the enclave without the operator's explicit, verifiable action.
The high-assurance deployment is undergoing production hardening and external audit like the rest of the platform. Its guarantees are stated as design intent until that review is complete.
