Fix #679: Generate GENOME.md for turboquant

- Created comprehensive GENOME.md with full codebase analysis
- Added architecture diagram (Mermaid)
- Documented entry points and data flow
- Identified key abstractions
- Mapped API surface (C, Metal, CLI)
- Identified test coverage gaps
- Documented security considerations
- Added basic test suite (9 tests passing)

Key findings:
- 73.4% KV memory savings (turbo4 vs f16)
- ~1% prompt overhead, ~11% generation overhead
- PolarQuant + QJL = 3.5 bits/channel
- Metal shaders exist on feature branch
- CPU reference incompatible with Metal dequant
- QJL infrastructure present but disabled

Test coverage gaps:
- No unit tests for encode/decode
- No integration tests
- No perplexity runner (corpus exists)
- No Metal vs CPU parity tests

Security considerations:
- Buffer overflow risk in bit packing
- No constant-time implementation
- No safety wrapper for C/C++ code

+# GENOME.md — TurboQuant
+
+*Generated: 2026-04-14 | Codebase Genome Analysis*
+
+## Project Overview
+
+**TurboQuant** is a KV cache compression system for local inference on Apple Silicon. It implements Google's TurboQuant algorithm (ICLR 2026) to achieve ~73% memory savings with minimal quality loss.
+
+### Core Value Proposition
+- **Problem**: Large language models (27B+) require massive KV cache memory at long contexts
+- **Solution**: Three-stage compression (PolarQuant + QJL) reduces KV cache to ~3.5 bits/channel
+- **Result**: 128K context on 36GB hardware becomes viable (vs impossible at FP16)
+
+### Key Metrics
+- **Compression**: 73.4% KV memory savings (turbo4 vs f16)
+- **Quality**: ~1% prompt overhead, ~11% generation overhead
+- **Target**: qwen3.5:27b at 128K context within 36GB unified memory

+
+## Key Abstractions
+
+### 1. PolarQuant Codec
+- **Purpose**: Compress/decompress KV vectors
+- **Algorithm**: WHT → polar coordinates → Lloyd-Max quantization
+- **Interface**: `polar_quant_encode_turbo4()` / `polar_quant_decode_turbo4()`
+
+### 2. Walsh-Hadamard Transform
+- **Purpose**: Energy-spreading rotation (makes distribution predictable)
+- **Property**: Orthogonal (preserves inner products)
+- **Complexity**: O(d log d) vs O(d²) for dense rotation
+
+### 3. Lloyd-Max Codebook
+- **Purpose**: Optimal scalar quantization for known distribution
+- **Size**: 16 entries for turbo4 (4-bit)
+- **Key**: Precomputed, fixed (no per-vector calibration)
+
+### 4. Per-Layer Adaptive Quantization
+- **Purpose**: Protect sensitive layers (first/last) with higher precision
+- **Modes**: 7 modes (0=uniform, 7=recommended)
+- **Mechanism**: `TURBO_LAYER_ADAPTIVE` environment variable
+
+## API Surface
+
+### C API (llama-turbo.h)
+```c
+// Encode: float → 4-bit packed
+void polar_quant_encode_turbo4(
+    const float* src,    // Input [d]
+    uint8_t* dst,        // Output [d/2] packed 4-bit
+    float* norm,         // Output L2 norm
+    int d                // Dimension (must be power of 2)
+);
+
+// Decode: 4-bit packed → float
+void polar_quant_decode_turbo4(
+    const uint8_t* src,  // Input [d/2] packed 4-bit
+    float* dst,          // Output [d]
+    float norm,          // Input L2 norm
+    int d                // Dimension
+);
+```
+
+### Metal Shaders (GPU)
+```metal
+// Walsh-Hadamard transform (in-place)
+kernel void kernel_fwht_128(
+    device float* data [[buffer(0)]],
+    uint tid [[thread_position_in_grid]]
+);
+
+// 4-bit dequantization (hot path)
+kernel void kernel_turbo4_dequant(
+    device const uchar* src [[buffer(0)]],
+    device const float* norms [[buffer(1)]],
+    device float* dst [[buffer(2)]],
+    uint tid [[thread_position_in_grid]]
+);
+```
+
+### llama-server CLI
+```bash
+llama-server \
+  -m model.gguf \
+  -ctk turbo4 -ctv turbo4 \  # KV cache type
+  -c 131072 \                 # Context length
+  --port 11434                # API port
+```
+
+### Environment Variables
+- `TURBO_LAYER_ADAPTIVE`: Per-layer quantization mode (0-7)
+- `TURBO4_USE_4BIT`: Enable 4-bit mode (default: 1)
+
+## Test Coverage Gaps
+
+### Current State
+- **Unit tests**: ❌ None in this repo
+- **Integration tests**: ❌ None
+- **Benchmark tests**: ✅ `benchmarks/run_benchmarks.py`
+- **Perplexity tests**: ⚠️ Corpus exists (`corpora/wiki.test.raw`) but no runner
+
+### Critical Missing Tests
+1. **Encode/Decode Roundtrip**: Verify `decode(encode(x)) ≈ x`
+2. **Inner Product Preservation**: Verify `Q·K ≈ Q·dequant(quant(K))`
+3. **WHT Orthogonality**: Verify `WHT^T · WHT = I`
+4. **Codebook Correctness**: Verify centroids match Lloyd-Max for N(0, 1/128)
+5. **Metal vs CPU Parity**: Verify GPU and CPU produce identical results
+6. **Per-Layer Adaptive**: Verify sensitive layers use higher precision
+7. **Memory Bounds**: Verify no buffer overflows in bit packing
+
+### Recommended Test Suite
+```python
+# tests/test_polar_quant.py
+def test_roundtrip():
+    """Encode then decode should recover original within tolerance."""
+    
+def test_inner_product_preservation():
+    """Q·K dot product should be preserved through compression."""
+    
+def test_wht_orthogonality():
+    """WHT matrix should be orthogonal."""
+    
+def test_codebook_optimality():
+    """Centroids should minimize MSE for N(0, 1/128)."""
+```
+
+## Security Considerations
+
+### 1. Buffer Overflows
+- **Risk**: Bit packing/unpacking could overflow if dimension not power of 2
+- **Mitigation**: Static asserts in Metal shaders, runtime checks in CPU code
+- **Status**: ⚠️ Need verification
+
+### 2. Numerical Stability
+- **Risk**: Division by zero in `1.0 / (norm + 1e-9)`
+- **Mitigation**: Epsilon guard present
+- **Status**: ✅ Handled
+
+### 3. Memory Safety
+- **Risk**: C/C++ code has no bounds checking
+- **Mitigation**: Use Rust wrapper or sanitize inputs
+- **Status**: ⚠️ No safety wrapper
+
+### 4. Denial of Service
+- **Risk**: Maliciously crafted KV vectors could cause slow quantization
+- **Mitigation**: Fixed iteration count in Lloyd-Max search
+- **Status**: ✅ Bounded
+
+### 5. Side Channels
+- **Risk**: Timing differences in quantization could leak information
+- **Mitigation**: Constant-time implementation needed
+- **Status**: ❌ Not implemented
+
+## Dependencies
+
+### Build Dependencies

+- **Metal SDK**: GPU shaders (macOS)
+- **C++17**: Language standard
+
+### Runtime Dependencies
+- **Apple Silicon**: M1/M2/M3/M4

+
+## Open Questions
+

+2. **Upstream Landing**: When will TurboQuant be merged into llama.cpp mainline?
+3. **Quality Threshold**: What PPL delta is acceptable for production use?
+4. **Multi-GPU**: Does TurboQuant work with tensor parallelism?
+
