about

nx_download_research_fetch.nx -- the Nishi RESEARCHER's sovereign fetch for DOWNLOAD ROBUSTNESS / SOTA (operator: "downloads should keep alive + keep downloading so we don't get broken fragments -- get to SOTA"). Grounds the robust-download engine (segment retry, resume, integrity, keep-alive, backoff) in primary sources. Mirrors nx_access_research_fetch (own TLS-1.3, Mozilla CA, idempotent have-skip). -> knowledge/ fetched/dl_*.raw. expect_exit: 0 license_tier: ORIGINAL
