Artifacts

“Preserved” means the archive holds the bytes and their digest. “Referenced” means it holds the record of them and nothing more. The archive does not claim a holding it cannot prove.

Questions this record answers

Each answer is composed only from fields this record carries, and names the attestation for what it says. A question the record cannot answer from its own attested content is not asked here. Where a boundary is described as official it was promulgated by an authority with the power to draw it and is not amended by anything on the vernacular layer; where it is described as vernacular it is held by attestation alone and amends no official boundary.
