- nip19.dart: bech32 encodeNpub/encodeNsec for raw keys (no TLV entities), verified against the canonical NIP-19 test vectors. - nip05.dart: verifyNip05 with an injectable http.Client plus a pure nip05MatchesPubkey helper for the .well-known/nostr.json check. - fetchProfileFor(fetcher, pubkey): fetches and parses any user's kind-0 into a typed NostrProfile (newest-wins), generalizing the own-key FetchProfile. - Export all three from swarm.dart; unit tests for each (bech32 vectors, MockClient HTTP cases, fake-relay profile parsing).
