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.

Candidates the archive declined

Identities that were considered and not asserted. They are published here rather than merely filed, because a refusal nobody can see is indistinguishable from never having looked. A candidate is HELD where the archive could not settle it and DECLINED where it could — and a wrong sameAs is worse than none. Every verdict is in the reconciliation ledger.
