nx_gossip.nx

nx_gossip.nx -- LIB: EPIDEMIC / ANTI-ENTROPY gossip so the Napster index spreads across the mesh with NO central bottleneck (operator: "lots of peers can share with lots of peers ... spoke to spoke or hub to hub"). Each node holds a local content registry (nx_dist_index rows). A gossip round reconciles two nodes: exchange a compact DIGEST (the set of cids each holds) -> each side selects the rows the other LACKS -> merge (idempotent by cid). After a symmetric round both nodes hold the UNION -> run pairwise across the mesh and knowledge converges epidemically. Composes nx_dist_index (row parsing, di_has_cid). No TLS. license_tier: ORIGINAL
