A maintainable, extensible BitTorrent client (C11, Linux/io_uring) targeting 10 GbE saturation. All torrent functionality is built from scratch; liburing is the only linked third-party dependency on the data path. Implements Phases 1-7 of the roadmap: - core: page-aligned buffer pool, MPMC/Treiber queues, bitfields, worker pool - crypto: SHA-1/256 (SHA-NI + scalar), Merkle (BEP-52), RC4 (MSE) - bencode/metainfo: zero-copy parser, v1/v2/hybrid .torrent + magnet - peer: sans-IO wire codec, MSE/PE handshake state machine, BEP-10, ut_metadata, PEX - piece/storage: block-level multi-peer engine, rarest-first + endgame, per-file completion events + single-file relocate (move-as-you-finish) - tracker/dht: HTTP + UDP (BEP-15) trackers, BEP-5 KRPC iterative lookup - platform: io_uring reactor (SQPOLL, registered buffers, SEND_ZC) - surface: versioned RPC, native plugin ABI, sandboxed Lua scripting, nautd/nautctl Verified against libtorrent (single/multi/hybrid, MSE, magnet-via-DHT, swarm); unit + interop tests green; ASan/UBSan/TSan clean.
