The Problem

Traditional AI systems can't be audited. They make decisions, but you can't:

• ✗ Reproduce the decision (non-deterministic)
• ✗ Prove it followed policy (no verification)
• ✗ Show evidence to regulators (no audit trail)
• ✗ Certify it for compliance (no formal proof)

The Solution: DSG

DSG is policy-controlled AI that proves every decision.

Policy → Deterministic Solver → Formal Proof → Execution → Evidence
         (Z3/QUBO)              (SHA-256)      (recorded)  (auditable)

Every decision is:

• ✅ Deterministic — same input always produces same output
• ✅ Provable — backed by Z3 formal verification
• ✅ Auditable — full evidence chain with SHA-256 hashing
• ✅ Compliant — CCVS L1-L5 evidence artifacts included

What is DSG?

A runtime governance engine for AI agents

Instead of letting AI decide directly, DSG:

1. Policy Input — Define rules in natural language (Thai/English supported)
2. Deterministic Gate — Route through Z3 SMT solver or QUBO optimizer
3. Formal Verification — Generate cryptographic proof (NVIDIA HPC + Z3)
4. Execution — Run agent with provable decision context
5. Evidence — Record audit trail with compliance artifacts

Result: AI decisions that can be replayed, audited, and certified 2+ years later.
