The very first result (`id: c9d747e235944b3f958db2eb17350c68_0`) is\n`\"source\": \"City of Boulder, Colorado\"` — not a DC dataset at all. Repeating the identical unscoped\ncall directly against the parent hub, `GET https://hub.arcgis.com/api/v3/datasets?page[size]=1`,\nreturns the **same total (21,221,305) and the same Boulder, CO dataset first** — confirming this is\nthe ArcGIS Hub v3 platform's own default behavior (every tenant's install of this API answers from one\nshared global catalog unless scoped), not a DC-specific misconfiguration. Adding the correct scope,\n`filter[orgId]=ePKBjXrBZ2vEEgWd` (DC's own ArcGIS org id, read off one of DC's own dataset records),\nnarrows the same call to a believable **574** total. `page[size]=3` is otherwise honored correctly\n(exactly 3 items back each time); only the *domain* of what's being paged was wrong without the org\nfilter. An unrelated query param name, `size=3` (JSON:API wants `page[size]`), is correctly rejected:\n`HTTP 400 {\"errors\":[{\"title\":\"Invalid Parameter\",\"detail\":\"'size' is an invalid parameter\"}]}`.\n\n**Freshness, by contrast, checks out here**: the DC-scoped catalog entry for \"Building Use and Square\nFootage Details\" carries `modified: 1791884114714` (2026-10-13T09:35:14Z); its downstream\nFeatureServer layer (`…/Building_Use_and_Square_Footage_Details/FeatureServer/0?f=json`) reports\n`editingInfo.lastEditDate` as the **identical millisecond timestamp** — unlike the Socrata/CKAN\nmetadata splits recorded elsewhere in this lane, ArcGIS Hub's per-dataset `modified` field here is\nsourced straight from the live service's own edit log and was accurate.\n\nHow observed: 2026-10-13, UTC 18:32Z–18:33Z, `curl` GET against `opendata.dc.gov`, `hub.arcgis.com`,\nand the DC FeatureServer on `services.arcgis.com`, no key, default UA.
