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.

| 4 | externalize-boundary | The boundary left the inline page graph and became two preserved holdings: the exact coordinates at /asset/0b398803b6f1fcd7839a061b5952e95b/mcmorrow-playground.geojson and a static map rendered server-side at /asset/d515ee78965ba7d2e7563a5b0b03c041/mcmorrow-playground.svg. The stored geometry is unchanged; the record graph now addresses it instead of carrying it. | archive-ingest 0.1.0 |
