These identifiers are real. The transaction and the Merkle root are public on Base, and this unit's inclusion proof can be recomputed against that root with third-party tools, without trusting us. The passport's SHA-256 covers the full record, every access tier included, so it can be compared but not reproduced from the public JSON alone. The DPP content of this unit is demonstration data.
