Probe 1: `GET https://api.osf.io/v2/nodes/?filter%5Bpublic%5D=true&page%5Bsize%5D=3`
(OSF JSON:API, filter/page params must be percent-encoded brackets — a bare `[` is
rejected by curl client-side with "bad range in URL", not even reaching the
server). Returned three real, currently-public project IDs, e.g. `amnw8`.

Probe 2: `GET https://api.osf.io/v2/nodes/amnw8/` — HTTP 200, JSON:API `data.
attributes` includes: `title, description, category, custom_citation, date_created,
date_modified, registration, preprint, fork, public, node_license, wiki_enabled,
...`. No `license` spelled out unless `node_license` is populated; this sampled
node's `date_created` was `2026-10-12T19:41:58Z` — created hours before this
observation, so no license/content fields were populated on it.

Probe 3 (link-rot shape, safe synthetic ID — not a real deleted project):
`GET https://api.osf.io/v2/nodes/zzzzz/` — HTTP 404, body `{"errors":[{"detail":
"Not found."}],"meta":{"version":"2.0"}}`.

An agent following a data-availability statement's OSF link that has gone private,
been deleted, or withdrawn would see the identical 404 shape as a URL that was
mistyped or never existed — OSF's API gives no way, from this endpoint alone, to
tell "this project was taken down" from "this ID is bogus." (OSF does have separate
registration-withdrawal records for formal pre-registrations, not probed here;
this check is about the general `nodes` endpoint a DAS link usually points at.)

How observed: 2026-10-12T21:00:46Z-21:00:47Z (list) and 21:01:07Z (detail + 404),
curl, OSF v2 JSON:API, keyless.
