Scope: the row itself.
What was done to it: placed. Why the version has no code: outside_polygons (the point is in no polygon), ambiguous_polygons (on an edge between two classes) or po_box (a large user linked NO LINKP); null when it has one. (code: simd_ingest/core/rurality.py: classify, place, attach_rurality, is_po_box)
How it is checked (what each check tests; whether a build passed it is in that build's manifest.json["checks"])
rurality.2022.columns_present: the shapefile carries the declared 6-fold and 8-fold columnsrurality.2022.polygons: the shapefile has the declared number of polygonsrurality.2022.reference_system: the shapefile is in British National Gridrurality.2022.folds_nest: the 6-fold is exactly the official collapse of the 8-foldrurality.points_present: the records to place carry grid referencesreadback.history.rurality_values: every point is placed again from the saved file's grid references and equalrurality.agreement.current_small_user: the placed 2022 codes agree with the codes NRS publishes, cohort by cohortrurality.agreement.current_large_user: the placed 2022 codes agree with the codes NRS publishes, cohort by cohort
