Live Cryptographic Demo
Below are three signed receipts produced by Sovereign agents in three different verdicts (committed, drift-flagged, guard-failed). The page server-renders the canonical body, the SHA-256 content hash, and the HMAC-SHA256 signature. Recompute either on your side under the demo secret demo-secret-do-not-use-in-production-v1 and you will get the exact same hex.

Triage ICSR intake batch 2026-04-15 (n=42). Flag expedited cases.
Output
Triage failed: 2 cases blocked by hallucination guard (verifier layer 6) — claims about drug-event association not supported by underlying case narrative. Routing to medical reviewer.

Paste any of the canonical projections above into the shell. The output is the same hex you see here.

Production receipts use a per-tenant secret derived from a master KEK + Ed25519 signatures alongside the HMAC. The demo strips that so the verification math is reproducible by anyone in 60 seconds.
Lindy, Clay, Manus, Relevance, CrewAI — none of them ship a signed artifact you can verify in a browser tab. Vanta and Drata sell scoreboards; we sell the cryptographic layer underneath every AI decision.
