  "breaks": "The main job, fetching a public page as markdown, could not be exercised here. On this computer DNS resolves public names (example.com, wikipedia.org) to 198.18.0.1, an address in the reserved 198.18.0.0/15 range used by the box's network proxy. The server correctly treats that as non-public and refuses: 'Refused to fetch https://example.com/robots.txt: example.com resolves to 198.18.0.1, which is not a public address.' That is this environment, not a tool bug. Pagination (start_index/max_length), raw=true, 404 and nonexistent-domain handling were therefore not observed on real content. --allow-private-ips was deliberately not used.",
