- Rewrote gemini-ui.lua to send native Neovim prompt selections, Ghost Text diff accept/reject actions, and smart context highlighting directly to the backend via zero-latency UDP port 3002, entirely replacing the old xecute_agent terminal subprocesses.
- Added prompt_user and preview_diff extmark lua functions for non-destructive diff review.
- Updated the Rust backend mcp-memory-server UDP listener to ingest the new gent_ask and interactive schema payloads and route them to the EventBus.
- Updated README.md and instructions.md with UDP documentation.
- Optimized memory allocation in router.rs by offloading JSON serialization to spawn_blocking and using references.
- Prevented full graph duplication on startup in state.rs index rebuild.
- Eliminated massive String allocations in QueryGraphPathHandler BFS loops.
- Avoided temporary Strings in VisualizeGraphHandler via inline writing.
- Fixed O(N) full-graph deduplication in MergeEntitiesHandler to scale efficiently.
- Offloaded the blocking idx.commit() inside index_committer_worker to okio::task::spawn_blocking to prevent the tokio async thread from being starved by blocking I/O.
- Removed expensive full HashMap .clone() operations during UI client websocket broadcasts in both handle_socket and
vim_telemetry_handler, filtering and collecting only the Sender handles.
- Migrated blocking std::fs::write calls across the WSL 9P boundary in
vim_telemetry_handler over to asynchronous okio::fs::write().await to prevent severe async thread blockages on native file I/O delays.
- Used a SessionCleanup Drop guard (RAII pattern) to guarantee that the websocket session is evicted from the global clients map and background read/write tasks are forcibly aborted even when Axum terminates the handler mid-execution due to a TCP connection loss.
- Removed heavy Tantivy index rebuild loop that ran every 5 seconds and rewrote entire graph to disk
- Converted polling worker to lightweight IndexWriter committer
- Fixed 67+ instances of unnecessary clone and string parsing overhead in tool return results
- Deduplicated state graph modification methods
- Added native E2E test suite in stub to validate server<->stub<->nvim IPC
- Added win-nvim integration tests
- Fixed empty capabilities schema in initialize response in server and win-nvim
- Refactored server to accept dynamic MCP_PORT for test isolation
- Made server exit gracefully on port 3000 collision
Makes apply_sync_write, write_to_local_delta, and store modify truly async, preventing the mcp-memory-server from locking the tokio executor during disk IO
