The token_env comment said the token goes to the first mirror's host; it goes to every configured mirror's own host (never to a redirect's). Co-Authored-By: Claude Opus 5.5 <[email protected]> Claude-Session: https://claude.ai/code/session_01912WaK6Rmew3wxZuPyX7E8

Native model downloads in pure Rust (L0, Apache-2.0): HTTP/1.1 over std sockets and rustls with the RustCrypto provider, without ring, aws-lc, C or assembly build dependencies. The wasm32 crate is empty.
Call download with bounded file specifications and ordered mirrors, or download_url for an exact catalog URL (including its query). Each file has a local filename independent of the URL, a size cap and optional pinned size/SHA-256. Transfers resume pinned .part files, verify before renaming, report progress and check cancellation during reads. Run on a worker thread. No proxy support; DNS resolution uses the platform resolver. Tokens are off by default and never forwarded to a different redirect host.
Tests use local synthetic HTTP servers for redirects, resume, truncation, cancellation, stalls, hashes, size limits and hostile specifications; they make no internet requests.
