about

nx_hifigan_stream_fetch.nx -- SOVEREIGN STREAMING DOWNLOAD of a large LFS model weight file. The high-level fetcher (nx_https_fetch_follow) buffers the whole response in memory and chokes on a 50MB+ body (returned NX_FF_GET=-4 on HF's LFS CDN). This mirrors that fetcher's connect+handshake+redirect loop EXACTLY, but streams the final body straight to a file fd via nx_https_get_stream (8MB window, no giant buffer). HF weights are LFS-hosted -> resolve/main/<file> 302s to cdn-lfs.huggingface.co with a SIGNED url (query string preserved by copying Location verbatim). Chrome-JA3 hello beats CDN anti-bot fingerprinting. This unblocks EVERY sovereign model-weight download (voice/image/LLM), not just this one. expect_exit: 0 license_tier: ORIGINAL
