This file is the append-only SOURCE the generator (scripts/gen-registry-lineage.mjs) READS — it is NEVER written by that generator, mirroring how registry generators read, never write, chaingraph.json (spec §5.2/§5.3). New real anchor-registration events (Sigsum, Rekor, or any future c2sp-tlog-proof-v1-shaped record) get appended to `records` below by a future row or operator, in the order they occurred. Each entry becomes exactly one leaf of the lineage log: its RFC 8785/JCS canonical JSON bytes (via chaingraph/kernels/_hash.mjs's cgCanon) are the raw entry bytes hashed with hashLeafNode. ⛔ Never reorder or edit an existing entry once it has been published as a leaf — that is exactly the drift SO #34's consistency gate exists to catch. This is PUBLIC transparency-log data (every byte already exists in a public log and already verifies offline); it is not secret.",
