about

nx_peer_meta_live.nx -- fetch the REAL torrent metadata from a REAL peer (X-TORRENT-LIVE-001 L3b): connect a real peer -> BEP-3 handshake -> BEP-10 ext handshake -> BEP-9 ut_metadata fetch (multi- piece) -> sha1(info-dict)==info_hash -> parse name/piece_length/length. Uses a DISPATCH LOOP (real peers interleave bitfield/have/choke -- not lockstep). Bounded connect via fork+parent-kill (L3a). Reuses cl_announce/cl_read_n/cl_write_n/cl_sockaddr (nx_peer_connect_live) + nx_bencode + nx_sha1. GATE = LIVE: any real peer yields a sha1-verified info-dict for Big Buck Bunny. license_tier: ORIGINAL module: nishi-core.torrent.peer_meta_live depends: nishi-core.torrent.peer_connect_live, nishi-core.torrent.bencode, nishi-core.crypto.sha1
