Chapter 05: Security & Integrity - Vault

APP_NODE: VAULT

PROTOCOL: SHA-256 Receipts & Merkle-Root Anchoring

1. CRYPTOGRAPHIC PROOF OF CUSTODY

Unlike legacy storage, Vault implements the Graylight Fairness Receipt: 1. HASH: Upon upload, the file is hashed using SHA-256. 2. ANCHOR: The hash is bundled into a batch and anchored to the Merkle-Root via `LedgerService`. 3. RECEIPT: A technical receipt is issued to the user, proving the exact state of the file at the time of upload.

2. DATA SILOING

No Data-Mining: Vault logic prohibits the scanning of user files for advertising or training purposes.

AES-256 Encryption: All assets are encrypted at rest using institutional-grade standards.

Sovereign Access**: Identity is managed via **Beacon (SSO), ensuring only authorized nodes can bridge to the storage layer.

3. AUDIT READINESS

Vault is "Series A Ready." All technical logs and integrity receipts are maintained in an audit-ready state for potential acquisition or institutional due diligence.
