# Tests
cargo test --all-features
✅ PASS (44 unit + 3 integration + 11 property tests)

# Coverage
make coverage
✅ PASS (95.58% coverage in 10.6s)

# Quality gate
make quality-gate
✅ PASS (lint + test + coverage)
```

### Demo Verification
```bash
# Run all three demos back-to-back
time cargo run --example benchmark_shootout --release
time cargo run --example gaming_leaderboards --release
time cargo run --example market_crashes --release
```

**Total Time**: ~30 seconds (compile + run all)
**Result**: ✅ All demos run successfully

## Release Notes Draft

### Trueno-DB v0.1.0 - Phase 1 MVP

**GPU-First Embedded Analytics Database** with SIMD fallback

#### Features

**Core Engine:**
- Apache Arrow storage backend
- Top-K selection (heap-based, O(n log k))
- Morsel-driven parallelism (128MB morsels)
- Out-of-core execution (Poka-Yoke safety)
- Cost-based backend dispatcher

**Backends:**
- SIMD via trueno crate (AVX-512/AVX2/SSE2/Auto-detect)
- GPU infrastructure (Phase 2 activation)
- Scalar fallback (portable)

**Quality:**
- 95.58% code coverage
- 11 property tests (1,100 test scenarios)
- Red team verified (no fraud detected)
- Zero clippy warnings
- Pre-commit hooks

**Examples:**
- `benchmark_shootout`: Technical performance (1K-1M rows)
- `gaming_leaderboards`: Gaming analytics (1M matches)
- `market_crashes`: Financial crisis analysis (95 years)

#### Performance

**Top-K Queries:**
- 1M rows: 12.8ms (Top-10), 22.4ms (Top-100)
- 100K rows: 1.2ms (Top-10), 2.5ms (Top-100)
- 24K rows: 0.04ms (Top-10)

**Speedup**: 2-10x vs scalar (SIMD-optimized)

#### Academic Foundation

**Data Sources:**
- Kenneth French Data Library (Dartmouth)
- Robert Shiller CAPE Data (Yale)

**Research Papers** (5 cited with DOIs):
- Schwert (1989) - Market volatility
- Roll (1988) - Global crash contagion
- Kirilenko+ (2017) - Flash Crash analysis
- Baker+ (2020) - COVID-19 market reaction

#### Installation

```bash
# Add to Cargo.toml
[dependencies]
trueno-db = "0.1.0"

# Or clone and build
git clone https://github.com/paiml/trueno-db
cd trueno-db
cargo build --release
```

#### Quick Start

```bash
# Run examples
cargo run --example benchmark_shootout --release
cargo run --example gaming_leaderboards --release
cargo run --example market_crashes --release

# Run tests
cargo test --all-features

# Check coverage
make coverage
```

#### Known Limitations (Phase 1)

- SQL parser exists but not integrated (uses direct Top-K API)
- GPU path requires `--features gpu` (not benchmarked yet)
- Single-node only (multi-GPU in Phase 2)
- Aggregations limited to Top-K (SUM/AVG/COUNT in Phase 2)

#### Next Steps (Phase 2)

- Multi-GPU local data partitioning
- Full SQL query execution
- Additional aggregations (SUM, AVG, COUNT, MIN, MAX)
- Distributed query processing
- Performance benchmarks vs DuckDB/Polars
