Adds a dedicated list of indexer relays, the aggregators that serve kind 10002 for arbitrary pubkeys, and uses it to resolve relay lists.

Until now purplepag.es was buried in DEFAULT_BOOTSTRAP_RELAYS, mixed with general purpose relays, and nothing targeted it for nip65. Apps that wanted an indexer list had to hardcode their own.

Summary by CodeRabbit

  • New Features

    • Added default indexer relays for discovering users’ NIP-65 relay lists.
    • Added configurable indexer relay settings, including the ability to disable indexer lookups.
    • Relay-list lookups can now use configured indexers, bootstrap relays, and additional known relays.
    • Exposed bootstrap and indexer relay configuration through the public package API.
  • Documentation

    • Defined “indexer relays” and related terminology.
  • Tests

    • Added coverage for discovering and refreshing relay lists through indexer relays.

📝 Walkthrough

Walkthrough

The change adds default indexer relay configuration to NDK. User relay-list discovery queries configured indexer relays, bootstrap relays, additional relays, and cached relay URLs. Tests validate NIP-65 lookup through an indexer relay.

Changes

Indexer relay discovery

Layer / File(s) Summary
Relay configuration and public exports
packages/ndk/lib/config/indexer_relays.dart, packages/ndk/lib/presentation_layer/ndk_config.dart, packages/ndk/lib/ndk.dart
Adds default indexer relay URLs, exposes NdkConfig.indexerRelays, and exports the configuration declarations.
Relay-list discovery flow
packages/ndk/lib/domain_layer/usecases/user_relay_lists/user_relay_lists.dart, packages/ndk/lib/presentation_layer/init.dart
Combines configured indexer, bootstrap, additional, and cached relay URLs for NIP-65 queries.
Discovery validation and terminology
packages/ndk/test/..., doc/common-terminology.md, packages/ndk/example/*.dart
Configures tests with explicit indexer relay settings, verifies NIP-65 lookup through an indexer relay, documents indexerRelays, and removes redundant example imports.

The test may miss a regression where refresh succeeds but the requested relay is not added.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert that the requested relay is added after refresh.

The test passes relayUrl: "wss://relay.added" to broadcastAddNip65Relay, and the returned UserRelayList should contain it. Without this assertion, an implementation that only returns the fresh list would still satisfy the existing fresh/stale assertions.

Proposed test assertion
       expect(list.relays.keys, contains("wss://relay.fresh"));
       expect(list.relays.keys, isNot(contains("wss://relay.stale")));
+      expect(list.relays.keys, contains("wss://relay.added"));

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
