# Proof Verification Portal (proof.vantages.app) — Cryptographic Evidence Validation

proof.vantages.app is the public cryptographic verification portal for Vantages Sovereign OS (VOS). It resolves KMS-signed SEAL hashes, human oversight decision packets, and immutable proof chain records.

## Verification & Proof Chain Traversal
The proof chain follows the canonical VOS traversal model:
`AI Proposed Action (proof_of_action) → Human Review (proof_of_review) → Oversight Decision (proof_of_approval / proof_of_override / proof_of_refusal) → Control Mapping (proof_of_control) → Evidence Record → optional VOS SEAL → Act Ledger → proof URL`.

## Safe-by-Design Privacy Standards
* **Reviewer Redaction:** `reviewerId` is retained internally; `reviewerDisplayName` is redacted by default on public proof URLs (`redacted_public`).
* **Zero-Knowledge Evidence:** Hashes and cryptographic proofs are publicly verifiable without exposing private client payloads or personal data.

## Fiduciary Disclaimer
Proof verification demonstrates structured evidence logging and cryptographic immutability of recorded events. It does not constitute automated legal certification or official regulatory clearance under the EU AI Act.
