- Add unified Tag-based model where e/p tags create intermediate Tag nodes
with REFERENCES relationships to Event/NostrUser nodes
- Update save-event.go: addPTagsInBatches and addETagsInBatches now create
Tag nodes with TAGGED_WITH and REFERENCES relationships
- Update delete.go: CheckForDeleted uses Tag traversal for kind 5 detection
- Add v3 migration in migrations.go to convert existing direct REFERENCES
and MENTIONS relationships to the new Tag-based model
- Create comprehensive test file tag_model_test.go with 15+ test functions
covering Tag model, filter queries, migrations, and deletion detection
- Update save-event_test.go to verify new Tag-based relationship patterns
- Update WOT_SPEC.md with Tag-Based References documentation section
- Update CLAUDE.md and README.md with Neo4j Tag-based model documentation
- Bump version to v0.36.0
This change enables #e and #p filter queries to work correctly by storing
all tags (including e/p) through intermediate Tag nodes.

- Implement TraverseFollows using Cypher path queries on FOLLOWS relationships
- Implement TraverseFollowers using reverse path traversal
- Implement FindMentions using MENTIONS relationships from p-tags
- Implement TraverseThread using REFERENCES relationships from e-tags
with bidirectional traversal (inbound replies, outbound parents)
- Add GraphAdapter to bridge Neo4j to graph.GraphDatabase interface
- Add GraphResult type implementing graph.GraphResultI for Neo4j
- Initialize graph executor for Neo4j backend in app/main.go
The implementation uses existing Neo4j schema and relationships created
by SaveEvent() - no schema changes required. The _graph extension now
works transparently with either Badger or Neo4j backends.

Introduce comprehensive integration tests for Neo4j bug fixes covering batching, event relationships, and processing logic. Add rate-limiting to Neo4j queries using semaphores and retry policies to prevent authentication rate limiting and connection exhaustion, ensuring system stability under load.
Replaces outdated Neo4j test setup with a robust TestMain, shared test database, and utility functions for test data and migrations. Improves Cypher generation for processing e-tags, p-tags, and other tags to ensure compliance with Neo4j syntax. Added integration test script and updated benchmark reports for Badger backend.
Merged 'Author' nodes into 'NostrUser' for unified identity tracking and social graph representation. Introduced migrations framework to handle schema changes, including retroactive updates for existing relationships and constraints. Updated tests, schema definitions, and documentation to reflect these changes.
Dgraph-related functionality, configuration, and benchmarks have been removed from the project. This streamlines the codebase to focus on supported backends, specifically eliminating Dgraph references in favor of Neo4j and other implementations. Version bumped to reflect the changes.
1. Added Err() method to CollectedResult (pkg/neo4j/neo4j.go:68-72):
- The resultiter.Neo4jResultIterator interface requires Err() error
- CollectedResult was missing this method, causing the type assertion to fail
- Since CollectedResult pre-fetches all records, Err() always returns nil
2. Fixed nil pointer dereference in buildCypherQuery (pkg/neo4j/query-events.go:173):
- Changed if *f.Limit > 0 to if f.Limit != nil && *f.Limit > 0
- This prevents a panic when filters don't specify a limit
3. Simplified parseEventsFromResult signature (pkg/neo4j/query-events.go:185):
- Changed from func (n *N) parseEventsFromResult(result any) to accept *CollectedResult directly
- This eliminates the runtime type assertion since ExecuteRead already returns *CollectedResult
- Removed the now-unused resultiter import
Replaced inline interface literals with dedicated, documented interface definitions in `pkg/interfaces/`. Introduced `TimeoutError`, `PolicyChecker`, and `Neo4jResultIterator` interfaces to clarify design, improve maintainability, and resolve potential circular dependencies. Updated config and constant usage rules for consistency. Incremented version to v0.31.11.
Bumped version to v0.31.10. Added extensive unit and integration tests for Cypher query generation in Neo4j, including validation of WITH clause fixes and handling optional matches for various event tagging scenarios. Ensures robust handling of references, relationships, and syntactical correctness.
Replaced individual environment variable access with a unified `DatabaseConfig` struct for all database backends. This centralizes configuration management, reduces redundant code, and ensures all options are documented in `app/config/config.go`. Backward compatibility is maintained with default values and retained constructors.
- Update nostr library to v1.0.3 with improved binary tag support
- Replace tag.Value() calls with tag.ValueHex() to handle both binary and hex formats
- Add NormalizeTagValueForHash() for consistent filter tag normalization
- Update QueryPTagGraph to handle binary-encoded and hex-encoded pubkeys
- Fix tag matching in query-events.go using TagValuesMatchUsingTagMethods
- Add filter_utils.go with tag normalization helper functions
- Update delete operations in process-delete.go and neo4j/delete.go
- Fix ACL follows extraction to use ValueHex() for consistent decoding
- Add binary_tag_filter_test.go for testing tag value normalization
- Bump version to v0.30.3
