Canada's lobbying registry: open.canada.ca CKAN catalog is plain GET, but every file it links on lobbycanada.gc.ca is Cloudflare-challenge-gated

# Canada Lobbying Registry (lobbycanada.gc.ca + open.canada.ca)

`open.canada.ca`'s CKAN catalog works as a normal, unauthenticated API:
```
curl -sS "https://open.canada.ca/data/en/api/3/action/package_show?id=70ef2117-1095-4d77-80eb-b87f2bada2a4"
```
→ `200 OK`, clean JSON, `"title": "Lobbying Registrations"`, listing two resources:
```json
[{"format": "CSV", "url": "https://lobbycanada.gc.ca/media/zwcjycef/registrations_enregistrements_ocl_cal.zip"},
 {"format": "XLS", "url": "https://lobbycanada.gc.ca/media/hcvmsu4e/dictionary_registrations_dictionnaire_enregistrements.xlsx"}]
```
`metadata_modified: 2026-08-10T10:11:01` on both resource entries.

Fetching the catalog's own linked file:
```
curl -sS -D - -o /dev/null https://lobbycanada.gc.ca/media/zwcjycef/registrations_enregistrements_ocl_cal.zip
```
→ `HTTP/2 403`, `cf-mitigated: challenge`, a Cloudflare managed-JS-challenge page
(`<title>Just a moment...</title>`) — the exact URL a public open-data catalog advertises as
a downloadable resource cannot be fetched by a plain HTTP client. The live register search
API shows the identical pattern:
```
curl -sS -D - -o /dev/null "https://lobbycanada.gc.ca/app/secure/ocl/lrs/do/lstRg?v2=true"
```
→ same `403 cf-mitigated: challenge` shape. Both the bulk static asset and the dynamic search
endpoint sit behind the same Cloudflare challenge — it is domain-wide, not specific to the
"live search" surface one might expect to be the gated part.

This is the same failure shape observed on the US House's `lda.congress.gov/LDWebBeta/` (see
companion record) — see the cross-service finding on this pattern.

How observed: 2026-10-05T08:49Z–08:50Z, curl GET against the CKAN `package_show` API, the
CKAN-linked ZIP resource, and the register's own search endpoint.

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.
