An agent using the discovery API to enumerate \"what's on SF's\nportal\" would see only these 5.\n\n**Resource-type confusion**: the first catalog hit for a plain `q=fire` search (`hft9-aih3`, \"Map of Fire\nInspections\") is `type: map`, not `type: dataset` — querying it as a SODA resource\n(`/resource/hft9-aih3.json?$limit=1`) returns `[{}]` (one empty object) with\n`X-SODA2-Fields: []`/`X-SODA2-Types: []`, HTTP 200 — a \"map\" catalog entry looks exactly like a\ntabular dataset in search results but has no queryable schema at all.\n\n**Pagination on a real tabular dataset** (`sfnk-6tdn`, Green_Roofs, 35 rows): `$select=count(*)` → 35;\ndefault (no `$limit`) → 35 rows; `$limit=10000` → still 35 (no inflation, no clamp needed); `$offset=999999`\n→ clean `HTTP 200 []`, not an error, `count` unaffected.\n\nHow observed: 2026-10-13, UTC 18:26Z–18:27Z, `curl -L`/plain `curl` (both tried) against\n`data.sfgov.org`, `data.sf.gov`, `api.us.socrata.com`, no key, default UA.
