`is_transient_io` only recognized `ENOBUFS` on unix; on Windows the `#[cfg(not(unix))]` arm returned `false`, so `WSAENOBUFS` (10055) — which Rust maps to `ErrorKind::Uncategorized`, missing the `WouldBlock` arm — propagated out of the USO `send_gso` path through `Session::send_sealed` and killed the session with `native::stream` "send failed — stopping stream". A high-bitrate keyframe burst (one `WSASendMsg` USO super-buffer is up to ~512 segments) momentarily exhausts the socket send buffer / AFD non-paged pool; it's a lossy drop that FEC + the next frame recover, exactly like the unix `ath11k` `ENOBUFS` case the classifier already handles. Fires independently of client platform (Windows/macOS clients both saw the crash) because it's the Windows *host's* send socket. Add a `#[cfg(windows)]` arm matching `WSAENOBUFS` plus the `WSAENET*`/`WSAEHOST*` network-path family (the Windows counterparts of the droppable unix set), and extend the classifier test with per-platform raw-errno coverage so the Windows CI runner exercises the 10055 path.
