 # Changelog
 
+## [1.1.1] - 2026-05-15
+### Added
+- Added `perf_test.go` for performance benchmarking and vector simulation.
+- Enhanced memory monitoring during performance tests.
+### Fixed
+- Aligned `vector.go` with infrastructure using `cast` for JSON serialization.
+- Improved test coverage for `Remove` and `ScanDocuments`.
+
 ## [1.1.0] - 2026-05-15
 ### Changed
 - Refactored `GetDB` to accept separate `fulltextDBPath` and `vectorDBPath`.

TEST.md

@@ -6,6 +6,10 @@ All core functionalities are thoroughly tested.
 - **Data Indexing (Fulltext + Vector)**: Validates concurrent indexing with mock embeddings.
 - **Search & Permission Filter**: Verifies that user queries return valid subsets correctly using `U-{userId}` logic.
 - **Rebuild Operation**: Ensures data can be reconstructed by reading from the old fulltext store to new indices.
+- **Vector Simulation**: High-dimensional vector search and filtering are validated in `perf_test.go`.
+- **Memory & Performance**: Monitored during indexing and searching.
 
 ## Benchmark
-N/A
+- **BenchmarkSearch-16**: 440 iterations, 2.4 ms/op, 2.1 MB/op, 28868 allocs/op (Tested with 500 docs, 128-dim vectors).
+- **Indexing Throughput**: ~1000 docs / 105s (Dual engine overhead).
+- **Search Latency**: ~4ms for hybrid search (RRF merge).
