Deterministic Reasoning (GPX) Engine Online

VERITAS

The logical backbone of the CAI stack — a formal reasoning engine where every inference chain is mathematically constrained, auditable from premise to conclusion, and immune to stochastic drift. Truth is not approximated. It is proven.

Statistical approximation is acceptable in many domains. In defense-critical autonomous systems it is not. VERITAS was engineered from first principles to eliminate inference drift — every conclusion it produces is formally derivable, every reasoning path is inspectable, and hallucination is architecturally impossible, not probabilistically unlikely.

Formal Logic Substrate (GPX)

Built on a Guided Provable eXecution (GPX) substrate that constrains all inference within a formal logical calculus. Conclusions are derivable from stated premises — no statistical interpolation, no learned shortcut pathways.

Deterministic Inference Graphs

Every reasoning step is represented as a node in an auditable directed graph. The full derivation path from input premise to final conclusion is preserved, traversable, and exportable for independent verification.

Contradiction Detection

Active contradiction monitoring across all live reasoning threads. Conflicting premises are flagged, isolated, and surfaced to CAI before any downstream action is permitted — preventing decisions built on inconsistent knowledge states.

Proof-Traceable Conclusions

Every VERITAS output includes a compact proof certificate linking the conclusion to its authorizing premises, enabling independent verification of reasoning correctness without re-executing the full inference chain.

Inference Determinism 100% Identical inputs produce identical outputs
Conclusion Traceability 100% Every output includes proof certificate
Logic Consistency > 99.97% Validated across test scenario corpus
Readiness TRL 4–5 Formal verification in progress

Upstream Relationship

VERITAS receives structured signal representations from CORTEX and symbolic knowledge constructs from CEREBRAL, applying formal inference to convert structured inputs into proof-backed conclusions that can be acted upon.

Operational Function

Maintains concurrent inference threads for active mission scenarios, detecting contradictions across threads, managing premise confidence weighting, and issuing conclusions with explicit confidence bounds and derivation certificates.

Downstream Outputs

VERITAS conclusions are passed to CERTUS for governance evaluation and to CAI for cognitive state integration. Each conclusion includes a machine-readable proof bundle enabling downstream components to independently verify the reasoning.

High-Assurance Decision Support

Provably correct reasoning for environments where decision auditability is a legal or operational requirement.

Adversarial Reasoning Validation

Contradiction detection and logic integrity verification in adversarial information environments.

Explainable AI Compliance

Formal reasoning output for programs requiring demonstrable explainability under DoD AI ethics and acquisition frameworks.
