  "changes": "Dissolve source units by explicit current first-level codes; simplify nine mapped regions and the unlabelled remaining national context together. Snap exterior edges to seven decimals, retaining source hole rings. Preserve all components and original component interior points; normalize D3 winding.",
  "limits": "A maintained SGIS-derived snapshot, not a newly surveyed 2026 cadastral dataset. The seven unmapped regional groups are used only for national context; their individual authority or shared-edge accuracy is not certified. Three tiny source-edge mismatches among Seoul/Gyeonggi/Incheon disappear within national-context union; no additional regional records are published."
