How Sturna Handled It

  1. Step 1: KNN routing → Compliance-Mapper agent (bid: 0.94, latency: 47ms)
  2. Step 2: MUG 4-round debate → factual_score: 0.91, no abstention triggered
  3. Step 3: G5 Tool-Grounded Detection → EUR-Lex verified, 3 citations confirmed
  4. Step 4: Guardian policy gate → passed, no prohibited practice flags
  5. Step 5: zk-SNARK proof generated → verifiable on zkSync Era Sepolia
Guardian policy gate: passed — no prohibited practice flags. Coalition bid adjacency bonuses applied. Full transparency card: AuditLogger ID + HMAC signature + D4 bonus applied.

Why It Matters

Only compliance AI with cryptographically verifiable outputs. Every execution is signed, logged immutably, and provable — not just claimed.

zk-SNARK proof means the GC can prove to regulators the AI system was audited. A regulator can independently verify the audit trail without trusting Sturna directly.

Aug 2 deadline: 30 days. Most enterprises are not ready. The window for achieving and documenting compliance is closing fast.
