about

nx_http_fetch.nx -- EAT THE DEBT: a plaintext HTTP (port 80, no TLS) fetch so HTTP-ONLY hosts are reachable. images.cocodataset.org is an S3 static-website endpoint (HTTP-only) -> the TLS-only fetcher fails at handshake (-3). This wires the SHIPPED pieces: nx_dns_a_resolve (host->IPv4, copied self-contained) + nx_http_client_get (socket+GET+drain) + a minimal status/redirect parse. Follows http:// redirects (a redirect to https:// is reported -- that host wants TLS, use the https fetcher). File-driven (data/mp_img_url.txt -> data/mp_img_dest.txt). license_tier: ORIGINAL expect_exit: 0
