1// nx_torrent_bench.nx -- the 1:1 torrent leaderboard, graded vs RESEARCH-VERIFIED incumbents.
2//
3// module: nishi-core.torrent.bench
4// depends: nx_swarm_sim.nx (-> stream_picker -> piece_manager), nx_sha256.nx, nx_syscalls.nx
5// capability: CORE_COMPUTE
6// wired_status: FULLY_WIRED
7//
8// Pitwall discipline (the plan's 1:1 mandate): grade each column S/A/B/C/D against the BEST
9// incumbent, label every cell MEASURED (we ran it) vs HANDED (incumbent value from a verified
10// primary source, NOT something we ran) vs PENDING (needs the live socket loop, named honestly).
11// We win, by construction + measured, on the columns no incumbent has: determinism/replay,
12// zero-egress-by-construction, reproducible adverse-swarm completion, deterministic streaming,
13// and a v2 (SHA-256) substrate rqbit still lacks. We do NOT claim throughput/memory wins -- those
14// are PENDING the live loop, and the research says clients cluster near link-bound anyway.
15//
16// VERIFIED incumbent facts baked into the leaderboard text (sources, 2026-06 research pass):
17// - libtorrent defaults: connections_limit=200, connection_speed=30/s, utp_target_delay=100ms
18// [libtorrent.org/reference-Settings.html]
19// - CVE-2024-51774: qBittorrent ignored SSL cert validation ~14.5y, CVSS 8.1 HIGH, fixed 5.0.1
20// [nvd.nist.gov/vuln/detail/CVE-2024-51774]
21// - rqbit: hashing (SHA-1) is the #1 CPU cost; NO BitTorrent v2 yet (planned, issue #546)
22// [github.com/ikatson/rqbit, issues/546 2026-02-02]
23// - libtorrent 2.0 has v2 (SHA-256/merkle, 16KiB leaf) [blog.libtorrent.org 2020-09];
24// Transmission 4.0 reads v2/hybrid; concrete hashing MB/s is UNPUBLISHED for every client
25// - ckerr 2010: clients cluster 53-60min near link-bound, "client choice makes little difference"
26// [gist ckerr 89882362...]; no modern quantified cross-client study exists
27// - RFC 6817 LEDBAT one-way target 100ms; LEDBAT++ is an IRTF draft (not an RFC), no BT-client impl
