This fixes issue #30 where search() returned empty results after
application restart when using storagePath persistence.
Changes:
- Modified VectorDB::new() to rebuild index from persisted vectors
- Uses storage.all_ids() and index.add_batch() for efficient rebuilding
- Added regression test test_search_after_restart
- Bumped version to 0.1.17
- Added ARM64 GNN npm package structure
The fix loads all persisted vectors and rebuilds the HNSW index
on initialization, ensuring search() works correctly after restart.

The project now compiles successfully with only warnings (unused imports/variables).
* fix(mathpix): Add missing test dependencies and font assets
- Add dev-dependencies: predicates, assert_cmd, ab_glyph, tokio[process], reqwest[blocking]
- Download and add DejaVuSans.ttf font for test image generation
- Update tests/common/images.rs to use ab_glyph instead of rusttype (imageproc 0.25 compatibility)
* chore: Update Cargo.lock with new dev-dependencies

- Detects CPU cores, SIMD capabilities (SSE2/AVX/AVX2/AVX-512/NEON)
- Analyzes memory availability and per-core allocation
- Checks dependencies (ONNX Runtime, OpenSSL)
- Validates configuration files and environment variables
- Tests network port availability
- Generates optimal configuration recommendations
- Supports --fix to auto-create configuration files
- Outputs in human-readable or JSON format
- Allows filtering by check category (cpu, memory, config, deps, network)
* fix(scipix): Add required-features for OCR-dependent examples
- Add required-features = ["ocr"] to batch_processing and streaming examples
- Fix imports to use ruvector_scipix::ocr::OcrEngine instead of root export

Build Fixes:
- Add Hash, Eq derives to Label type for HashMap compatibility
- Fix PropertyValue enum - add List variant as alias for Array
- Fix LabelIndex to use label.name instead of Label struct as key
- Split cypher lexer alt() into nested calls (nom 21-alternative limit)
- Fix RoaringBitmap serialize method (use serialize_into)
- Add ordered-float dependency for Hash impl on float values
- Fix ReadOnlyTable usage (use iter().count() instead of len())
- Add VectorIndex trait import for HnswIndex methods
- Fix PropertyValue variant names in match statements (Boolean/Integer)

- ruvector-cluster: Distributed coordination with DAG-based consensus,
consistent hashing sharding, node discovery (static/gossip/multicast),
and load balancing across shards
- ruvector-raft: Full Raft consensus implementation following the paper
spec, including leader election, log replication, snapshots, and RPC
messages with bincode 2.0 serialization
- ruvector-replication: Data replication with sync/async/semi-sync modes,
vector clock conflict resolution, CRDT-inspired merge strategies,
change streaming with checkpointing, and automatic failover with
quorum-based decisions
All 56 tests pass across the 3 new crates. Fixed several issues during
review: bincode error types, Send bounds for async spawns, unnecessary
async methods converted to sync.
Critical fix for v0.1.7 that resolves native module loading failure.
Changes:
- Fixed case sensitivity: VectorDB → VectorDb in type checks
- Native module exports VectorDb (lowercase 'b')
- Code was checking for VectorDB (uppercase 'B')
- Re-export as VectorDB for API consistency
- Version bump: 0.1.6 → 0.1.7
This fix resolves the error:
"Native module loaded but VectorDB not found"
Related commits:
- Database pooling: already in storage.rs (commit 44ca725)
- Package name fixes: already applied (ruvector-core)
Next steps:
- Rebuild platform packages with pooling code
- Publish platform packages v0.1.2
