This certificate is a tamper-evident record of registration. It does not by itself establish originality or exclusive rights.
What this establishes: this registration was entered into the S.M.I. provenance chain on the date shown and has not been altered since — any change breaks the chain and fails verification.
What it does not establish: originality, authorship, or exclusive rights. It records what was submitted, not whether the claim is correct, and does not by itself resolve a competing claim.
Each anchor is a SHA-256 commitment in the SMI tamper-evident provenance chain. Scheme 2 anchors: recompute sha256(prev_hash + payload_hash + seq + created_at) — the registration date is inside the hash. Legacy anchors (no scheme field): sha256(prev_hash + payload_hash + seq).
