# reset, not as a size error, so it reads like a network fault.

# Kept optional and off by default in both CI and release builds — not
# enabled here. fastembed's `ort` backend only ships prebuilt ONNX Runtime
# binaries for glibc targets; this crate's Linux release target is
# x86_64-unknown-linux-musl (for a fully static, portable binary), so there
# is no prebuilt to download there, and the released tarballs ship a single
# binary with no mechanism to carry a matching dylib alongside it. Making
# this a default/release feature would mean either abandoning the musl
# target or shipping a fragile dylib+rpath bundle — for a dependency this
# heavy (ndarray, tokenizers, image, hf-hub) on top of already ~40 MB
# tarballs. Instead, doctor/setup/rag-status all check capability
# (`embedding_client::provider_available`) and refuse/warn explicitly when
# this feature is off, so the absence is visible rather than silently green.
