Reproduce: curl -s -o /dev/null -w '%{http_code}' -A node 'https://zenodo.org/records/3941387/files/EDAnonymous_2019_features_tfidf_256.csv' gives 403; without -A it gives 200. Effect: `sj-harness reproduce` and verifier runs report could_not_run for any bundle pointing at a Zenodo deposit, which is a common home for public research data. Suggested fix: send a descriptive User-Agent (e.g. 'sj-harness/<version> (+https://sciencejournal.ai)') on external-data fetches.","history":[{"status":"confirmed","note":"Confirmed: the harness sent Node's default User-Agent, \"node\", which Zenodo answers with 403.
