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.

What does the archive's map of Mission Hill show?
A static map of the boundary, rendered by the archive on a server and never in a reader's browser, served as image/svg+xml at /asset/1cf2aa3654a333624ab89c2f5e307306/mission-hill-2.svg. The exact coordinates it was drawn from are served separately as application/geo+json at /asset/8d8d0c65a07b9e2019d0b8d5732bad5a/mission-hill-2.geojson.

What does the wider world call Mission Hill?
It asserts none, deliberately. 2 candidates were considered and not asserted: Mission_Hill,_Boston (declined) — Rejected by adjudication (POL-2): this record is the City of Boston's Mission Hill Main Streets district, and /place/mission-hill is the Mission Hill neighborhood; Q1939043 (declined) — Rejected by adjudication (POL-2): this record is the City of Boston's Mission Hill Main Streets district, and /place/mission-hill is the Mission Hill neighborhood. A wrong sameAs is worse than none: under OWL semantics it instructs a consumer to merge two things into one, so the archive asserts an identity only where it can defend it and publishes the refusal where it cannot. Every verdict is in the reconciliation ledger at /reconciliation.

Candidates the archive declined
Identities that were considered and not asserted. They are published here rather than merely filed, because a decision nobody can see is indistinguishable from never having looked. A candidate is DECLINED where the archive weighed it and refused it, and HELD where the archive asserts it nowhere on this record — most often because it is asserted on the archive's principal record for the same place, and asserting it twice would instruct a consumer to merge two records the archive deliberately keeps apart. Each row states which, in its own words. A wrong sameAs is worse than none. Every verdict is in the reconciliation ledger.
