35 tests define the full resolver contract using live DNS queries against *.dns.sneak.cloud (Cloudflare). Tests cover: - FindAuthoritativeNameservers: iterative NS discovery, sorting, determinism, trailing dot handling, TLD and subdomain cases - QueryNameserver: A, AAAA, CNAME, MX, TXT, NXDOMAIN, per-NS response model with status field, sorted record values - QueryAllNameservers: independent per-NS queries, consistency verification, NXDOMAIN from all NS - LookupNS: NS record lookup matching FindAuthoritative - ResolveIPAddresses: basic, multi-A, IPv6, dual-stack, CNAME following, deduplication, sorting, NXDOMAIN returns empty - Context cancellation for all methods - Iterative resolution proof (resolves example.com from root) Also adds DNSSEC validation to planned future features in README.
