## Row-limit clamps vary sharply by deployment
- CKAN's `package_search` commonly clamps `rows` to 1000 regardless of the requested value, returning HTTP 200 with the `count` field unchanged [obj_01M3QYS655E88C20VF5SV92SGC].
- open.canada.ca clamps `rows` to 1000 (producing a 12.9 MB page) [obj_01M3RNKCFM9WPAKN6H501YM93D], and separately hard-clamps `datastore_search` at exactly `limit=32000` regardless of a requested 40000 or 100000 [obj_01M45Q4H3RQA43KH37J79KHAE5].
- data.gov.uk [obj_01M4V92WMFG43NHQM51ZKCWC53], GovData.de (a 16 MB page) [obj_01M3RNN3KAPCJ5WNP18KSWGTTV], and Latvia's data.gov.lv [obj_01M45TMH84B5EC989HC1A40FRB] all confirm the same ~1000-row clamp.
- California's data.ca.gov is an outlier: `datastore_search` and `datastore_search_sql` both clamp at 50,000 rows instead of the usual 1,000 [obj_01M45Q9T90E446JK870QBWBAJF], and a cross-state comparison frames US state portals as disagreeing hard on row-cap philosophy — CKAN governs tightly on some, Socrata mostly doesn't cap, ArcGIS hard-caps at 1k [obj_01M45QG5BAAQHNCVVXEWZG2HS9].

## Many national deployments are unreachable or gated outright
- US catalog.data.gov's entire API, including the mandated data.json manifest, 404s behind CloudFront [obj_01M4V92V08SG9GYMR1PDAFWC5Q].
- Australia's data.gov.au legacy `/api/3/action/*` namespace 404s behind Drupal with robots.txt disallowing all [obj_01M45TM0QNJHWRFTK3RS2EQNHE]; its `datastore_search` separately answers 302 with no Location plus a Drupal 404 body, while `datastore_search_sql` leaks a raw psycopg2 error [obj_01M3RNKT6N71PYMNRKK3DS8C20].
- Mexico's datos.gob.mx is blocked by Akamai on every call [obj_01M45HWCJN4T64WM7TQ8K9R4HG]; Thailand's data.go.th by a branded WAF [obj_01M45HX87J2SF2E830TM07YGXT]; Kenya's opendata.go.ke has no CKAN left, with two different dead-backend 404 shapes [obj_01M45HWSFQ5M4H9T22MJDR96C6]; Peru's datosabiertos.gob.pe has only `package_list` actually wired up, every other action hitting the portal's own themed 404 [obj_01M45HWMMA22SJY0XC49TB1N6G].

## Fronting layers mask or rewrite CKAN's own errors
- GovData.de's www proxy keeps CKAN's status codes but replaces every error body with a generic Apache HTML page, while the direct host returns real CKAN JSON in German [obj_01M3RNN3KAPCJ5WNP18KSWGTTV]; its `package_search` also swallows malformed Solr syntax to a clean `count:0` with no parser error [obj_01M45RE756QNECDNRSJT6J8ET7].
- Uruguay answers a deliberately invalid action not with CKAN's normal 400 but with a government WAF "security error" page at HTTP 200 [obj_01M45HWP702Z0FTHZQSQY75B8Q].

## Working instances still carry local quirks
- Argentina's CKAN works cleanly, but its separate time-series API caps `limit` at 5000 with Spanish error text [obj_01M45HWE626J420PHR2T9T8RD8], differing in shape from Chile's own Spanish-language errors [obj_01M45HWHCWFXXGDE4MTWQ4RR38].
- The Canadian Space Agency's portal UI shows a `/data/api/...` path that 404s on a real action, because the live API root drops the `/data` segment [obj_01M45P1QECQB8TRWYBY3WB9HAA]. Canada's open.canada.ca catalog itself is a plain GET, but every linked file on lobbycanada.gc.ca is Cloudflare-challenge-gated [obj_01M45M9HGCJ8S0MTSN3K56NRED]. National Grid ESO rebranded to NESO, moving hosts but keeping the same CKAN API [obj_01M45DWHBJJBK9145NNJABQQZT].
- A cross-cutting finding notes "national open-data portal" covers at least four unrelated platforms even within one region [obj_01M45TN4851ZWK06JQN91G5P2S], and a broader multi-continent finding shows "key required" answered as a 200, 401, 403, or 0-byte 401 depending on country and output format, with page-past-the-end a 404, 200-empty, or 500 [obj_01M3RNPCTX2NTY2NRCS1V81568].

## Disagreements and open questions
California's data.ca.gov clamps CKAN datastore endpoints at 50,000 rows [obj_01M45Q9T90E446JK870QBWBAJF], while open.canada.ca, data.gov.uk, GovData.de, and Latvia all clamp at roughly 1,000 [obj_01M3RNKCFM9WPAKN6H501YM93D][obj_01M4V92WMFG43NHQM51ZKCWC53][obj_01M3RNN3KAPCJ5WNP18KSWGTTV][obj_01M45TMH84B5EC989HC1A40FRB] — the cross-state comparison explicitly frames this as unresolved inconsistency rather than a documented tier system [obj_01M45QG5BAAQHNCVVXEWZG2HS9].

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
