about

nx_peer_metadata.nx -- BEP-9 ut_metadata FETCH + sha1-verify the info-dict (X-TORRENT-LIVE-001 R3b): COMPLETES the engine. A magnet has no .torrent, so the client fetches the info-dict from a peer over BEP-10/BEP-9: ext handshake -> learn ut_metadata id + metadata_size -> request each metadata piece -> peer replies a bencoded header + RAW info-dict bytes -> assemble -> the BEP-9 integrity check sha1(info-dict)==info_hash -> nx_bc_dict_get the piece map (name/piece length/ length). Reuses nx_peerwire + nx_bencode + nx_sha1. GATE = SOVEREIGN LOOPBACK: a synthetic info-dict whose sha1 IS the handshake info_hash; the mock serves it; the client fetches, assembles, verifies, and parses. license_tier: ORIGINAL module: nishi-core.torrent.peer_metadata depends: nishi-core.torrent.peerwire, nishi-core.torrent.bencode, nishi-core.crypto.sha1
