- Replace C Tor (0.4.8.21) with Rust Arti (1.9.0/arti-client 0.38) - 70% smaller binary: 21MB xcframework vs 67MB (6.9MB vs 14MB per slice) - Memory-safe Rust implementation with modern async (tokio) - Same SOCKS5 proxy interface at 127.0.0.1:39050 for drop-in compatibility - FFI wrapper (arti-bitchat crate) with C-compatible exports - Swift TorManager maintains identical public API - Aggressive size optimization: opt-level=z, lto=fat, panic=abort, strip - Supports iOS device, iOS simulator (Apple Silicon), and macOS Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
