| 4 | externalize-boundary | The boundary left the inline page graph and became two preserved holdings: the exact coordinates at /asset/339b8adcf10fc0e093a4a823ef9ae580/poplar-street-play-area.geojson and a static map rendered server-side at /asset/1fbd227662ff222035180124f8eb6ad5/poplar-street-play-area.svg. The stored geometry is unchanged; the record graph now addresses it instead of carrying it. | archive-ingest 0.1.0 |
