1. **No `openssl-sys` compilation** - The build used `rustls`, `ring`, and `tokio-rustls` instead
2. **All dependencies are pure Rust** - No C compilation required
3. **Build completed in 6.39s** - Fast compilation without vendored OpenSSL
The single-line change to `crates/review/Cargo.toml` switches from the default OpenSSL TLS backend to Rustls, which avoids the `openssl-sys` build failure in CI. This matches the pattern already used by `crates/remote`.
