Same Saudi Open Data Licence review item as GASTAT — still open, and composition does not close it. Composed into land_value_sqm by SS-1-14 (baseline.compose_land_value) as the median of each district's monthly prices over a trailing 12-month window. Two caveats travel with every value and belong here too: the figure has DISTRICT granularity stored per hex, and the geography that places it on hexes is the `ksa_districts` layer, whose provenance is NOT established. Crediting SREM for these values is correct; treating the column as cleared for redistribution is not, until `ksa_districts` is resolved.

District boundaries: source unverified. Supplied without attribution or licence; provenance not established. Not cleared for redistribution or client-facing display.

⚠️ NEEDS REVIEW BEFORE ANY USE BEYOND STAGING. No attribution, licence text or upstream URL accompanied this file. The property schema (district_id / city_id / region_id / name_ar / name_en) resembles Saudi National Address / SPL lineage but that is a resemblance, not a provenance. This layer supplies the geography that lands land_value_sqm on hexes and it carries NO population field — it is a district polygon layer, not a district census, so SS-1-04 census calibration and the ±5% district exit gate remain unevaluable and the banking and clinic profiles must keep refusing to score. SS-1-14 has since composed land_value_sqm through these polygons, and SS-1-08 composed the modelled affluence_index on top of that column, which it requires; both widened the exposure and resolved none of it. Withdrawing the layer means NULLing those two columns — `compose_land_value`'s reset path and `compose_affluence.ODBL_DROP_SQL` do exactly that, and no third column reads this geography. PROVENANCE RESEARCH (see provenance_candidates): the file is now traced, by measurement, to a public GeoJSON whose own README says it was scraped from the Saudi National Address portal. That identifies the lineage and closes NOTHING — the stated licence is a software copyleft over data the publisher did not own. The question is still open and this entry still carries UNKNOWN_PROVENANCE. The layer's third and most visible consumer is not a column at all: district NAMES, which every client-facing deliverable prints. That exposure is now gated on the `district_names_cleared` capability (`baseline.clearance`), default False, so a deliverable renders reference ids and coordinates instead of names and stays releasable while this item is open.
