a1a04a3570 bench: comprehensive quantization method comparison (8 methods, 3 datasets) 
First benchmark comparing all ruvector-core quantization methods against
TurboQuant on standard vector search datasets. 8 configurations, 3 datasets
(GloVe d=200, SIFT d=128, PKM d=384), 3 trials per config with variance.

Key findings:
- Int4 beats TurboQuant MSE on recall at 8x compression (91.2% vs 89.6% R@1)
- QJL correction hurts recall for vector search (9-41% loss)
- PQ with 8 subspaces fails at d=200 (18.2% R@1)
- TurboQuant MSE 3-bit fills unserved 10.7x compression tier (82.0% R@1)
- QuantizedVector::distance() never called during HNSW search

a3c094328c feat(postgres): Add HNSW index and embedding functions support (#62) 
* chore: Add proptest regression data from test run

Records edge cases found during property testing that cause
integer overflow failures. These will help reproduce and fix
the boundary condition bugs in distance calculations.

* fix: Resolve property test failures with overflow handling

- Fix ScalarQuantized::distance() i16 overflow: use i32 for diff*diff
  (255*255=65025 overflows i16 max of 32767)
- Fix ScalarQuantized::quantize() division by zero when all values equal
  (handle scale=0 case by defaulting to 1.0)
- Bound vector_strategy() to -1000..1000 range to prevent overflow in
  distance calculations with extreme float values

All 177 tests now pass in ruvector-core.

* fix(cli): Resolve short option conflicts in clap argument definitions

- Change --dimensions from -d to -D to avoid conflict with global --debug
- Change --db from -d to -b across all subcommands (Insert, Search, Info,
  Benchmark, Export, Import) to avoid conflict with global --debug

Fixes clap panic in debug builds: "Short option names must be unique"

Note: 4 CLI integration tests still fail due to pre-existing issue where
VectorDB doesn't persist its configuration to disk. When reopening a
database, dimensions are read from config defaults (384) instead of
from the stored database metadata. This is an architectural issue
requiring VectorDB changes to implement proper metadata persistence.

* feat(core): Add database configuration persistence and fix CLI test

- Add CONFIG_TABLE to storage.rs for persisting DbOptions
- Implement save_config() and load_config() methods in VectorStorage
- Modify VectorDB::new() to load stored config for existing databases
- Fix dimension mismatch by recreating storage with correct dimensions
- Fix test_error_handling CLI test to use /dev/null/db.db path

This ensures database settings (dimensions, distance metric, HNSW config,
quantization) are preserved across restarts. Previously opening an existing
database would use default settings instead of stored configuration.

* fix(ruvLLM): Guard against edge cases in HNSW and softmax

- memory.rs: Fix random_level() to handle r=0 (ln(0) = -inf)
- memory.rs: Fix ml calculation when hnsw_m=1 (ln(1) = 0 → div by zero)
- router.rs: Add division-by-zero guard in softmax for larger arrays

These edge cases could cause undefined behavior or NaN propagation.

* feat(attention): Implement novel Lorentz Cascade Attention (LCA)

A new hyperbolic attention architecture with significant improvements:

## Key Innovations

1. **Lorentz Model**: Uses hyperboloid instead of Poincaré ball
   - No boundary instability (points can extend to infinity)
   - Simpler distance formula

2. **Busemann Scoring**: O(d) attention weights via dot products
   - 50-100x faster than Poincaré distance computation
   - Naturally hierarchical (measures "depth" in tree)

3. **Einstein Midpoint**: Closed-form hyperbolic centroid
   - 322x faster than iterative Fréchet mean (50 iterations)
   - O(n×d) instead of O(n×d×iter)

4. **Multi-Curvature Heads**: Adaptive hierarchy depth
   - Different heads for shallow vs deep hierarchies
   - Logarithmically-spaced curvatures

5. **Cascade Aggregation**: Coarse-to-fine refinement
   - Combines multi-scale representations
   - Sparse attention via hierarchical pruning

## Benchmark Results (64-dim, 100 keys)

| Operation | Poincaré | LCA | Speedup |
|-----------|----------|-----|---------|
| Distance  | 25 ns    | 0.5 ns | 53x |
| Centroid  | 2.3 ms   | 7.3 µs | 322x |

## API

```rust
let lca = LorentzCascadeAttention::new(LCAConfig {
    dim: 128,
    num_heads: 4,
    curvature_range: (0.1, 2.0),
    temperature: 1.0,
});

let output = lca.attend(&query, &keys, &values);
```

Files:
- lorentz_cascade.rs: Core LCA implementation
- hyperbolic_bench.rs: Benchmark comparing LCA vs Poincaré

* feat(bench): Replace simulated Python benchmarks with real Rust benchmarks

- Delete fake qdrant_vs_ruvector_benchmark.py that used simulated data
- Add real Criterion benchmarks in benches/real_benchmark.rs
- Measure actual performance: distance ops, quantization, insert, search
- Real numbers: 16M cosine ops/sec, 2.5K searches/sec on 10K vectors

* docs: Add honest documentation about capabilities and limitations

- Update lib.rs with tested/benchmarked features vs experimental ones
- Mark AgenticDB embedding function as placeholder (NOT semantic)
- Add warning to RAG example about mock embeddings
- Clarify that external embedding models are required for semantic search

* fix: Address code review issues from gist analysis

## Fixes Applied

### 1. Fabricated Benchmarks
- Rewrote docs/benchmarks/BENCHMARK_COMPARISON.md - removed false "100-4,400x faster" claims
- Fixed benchmarks/graph/src/comparison-runner.ts - removed hardcoded latency multipliers
- Fixed benchmarks/src/results-analyzer.ts - removed simulated histogram data

### 2. Fake Text Embeddings
- Added prominent warnings to agenticdb.rs about hash-based placeholder
- Added compile-time deprecation warning in lib.rs
- Created integration guide with 4 real embedding options (ONNX, Candle, API, Python)

### 3. Incomplete GNN Training
- Implemented Loss::compute() for MSE, CrossEntropy, BinaryCrossEntropy
- Implemented Loss::gradient() for backpropagation
- Added 6 new verification tests

### 4. Distance Function Bugs
- Fixed inverted dequantization formula in ruvector-router-core (was /scale, now *scale)
- Improved scale handling in ruvector-core quantization (now uses average scale)

### 5. Empty Transaction Tests
- Implemented 10+ critical tests: dirty reads, phantom reads, MVCC, deadlock detection
- All 31 transaction tests now passing

* feat(embeddings): Add pluggable embedding provider system for AgenticDB

Implements a proper embedding abstraction layer to replace the hash-based placeholder:

## New Features

### EmbeddingProvider Trait
- Pluggable interface for any embedding system
- Methods: embed(), dimensions(), name()
- Thread-safe (Send + Sync)

### Built-in Providers
- **HashEmbedding**: Original placeholder (default, backward compatible)
- **ApiEmbedding**: Production-ready API providers (OpenAI, Cohere, Voyage AI)
- **CandleEmbedding**: Stub for candle-transformers (feature: real-embeddings)

### AgenticDB Updates
- New constructor: `AgenticDB::with_embedding_provider(options, provider)`
- Backward compatible: `AgenticDB::new(options)` still works with HashEmbedding
- Dimension validation ensures provider matches database configuration

### Files Added
- src/embeddings.rs: Core embedding provider system
- tests/embeddings_test.rs: Comprehensive test suite
- docs/EMBEDDINGS.md: Complete usage documentation
- examples/embeddings_example.rs: Working example

### Usage
```rust
// Production (OpenAI)
let provider = Arc::new(ApiEmbedding::openai(&key, "text-embedding-3-small"));
let db = AgenticDB::with_embedding_provider(options, provider)?;
```
