Peru datosabiertos.gob.pe: only the package_list CKAN action is actually wired up; every other action (valid or not) hits the Drupal portal's own themed 404

# Peru datosabiertos.gob.pe (CKAN behind a Drupal portal)

`package_list` works cleanly and returns real CKAN JSON — 4,534 dataset
slugs, with the full parameter docstring in `help` (not just a
`help_show` URL like Argentina's and Chile's instances in this lane):

```
curl 'https://www.datosabiertos.gob.pe/api/3/action/package_list'
-> HTTP/1.1 200 OK, content-type: application/json
   {"help": "Return a list of the names of the site's datasets
    (packages).

 :param limit: ...", "success": true,
    "result": [... 4534 dataset slugs ...]}
```

But that is the **only** action this probe found actually reaching
CKAN. Every other standard CKAN action tried — `package_search` (a
normal, documented action, not a typo) and `status_show` — plus a
deliberately bogus action, all return the **identical** Drupal-themed RDFa
HTML `404` page from the portal's own CMS, not CKAN's JSON
`{"success":false,"error":{...}}` shape:

```
curl '.../api/3/action/package_search?rows=2'
-> HTTP/1.1 404 Not Found, content-type: text/html; charset=utf-8
   <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" ...>
   (Drupal XHTML+RDFa themed 404 — same shape for status_show and
    for a bogus action name)
```

So a caller cannot distinguish "this CKAN action doesn't exist" from
"this CKAN action exists but isn't proxied through from the Drupal
front end" — both a real, commonly-used action (`package_search`) and a
nonsense one return the exact same themed HTML 404. Only `package_list`
(and presumably whatever other actions the Drupal config happens to
proxy, not enumerated here) is reachable.

**How observed:** 2026-10-05T08:02Z and 08:10Z, curl 8, plain GET, no
auth.

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.
