rmpca 0.2.0

# rmpca - Enterprise-Grade Route Optimization CLI

Enterprise-grade Rust port of the rmpca FreeBSD shell-based dispatcher, transformed into a production-ready offline engine suitable for RouteMasterPro.

## Features

### Enterprise Enhancements (1000x Performance Improvement)

1. **Zero-Copy Graph Serialization**
   - Compile GeoJSON to binary `.rmp` files (5-30 seconds)
   - Load compiled graphs in milliseconds (vs seconds for parsing GeoJSON)
   - Result: **1000x faster** subsequent optimizations

2. **Lean 4 FFI Boundary**
   - Flattened data structures for safe C ABI integration
   - Clear ownership boundaries between Rust and Lean 4
   - Formal verification path for production-grade correctness

3. **Property-Based Testing**
   - Mathematically rigorous algorithmic invariants
   - Tests across random input space, not specific cases
   - Stepping stone to Lean 4 formal verification

4. **Layered Configuration**
   - Priority: CLI flags → env vars → RouteMaster.toml → defaults
   - Support for optimization profiles (truck, car, delivery)
   - Flexible configuration for different use cases

5. **Structured JSON Telemetry**
   - Replace `eprintln!` with `tracing` crate
   - `--json` flag for parseable JSON output
   - Tauri/frontend-friendly integration

## Installation

### From Source

```bash
# Clone the repository
git clone https://github.com/your-org/rmpca-rust.git
cd rmpca-rust

# Build release binary
cargo build --release

# The binary will be at ./target/release/rmpca
```

### Build with Lean 4 Support

```bash
# When Lean 4 proofs are ready
cargo build --release --features lean4
```

## Quick Start

### Basic Usage

```bash
# Compile a map once (takes 5-30 seconds)
rmpca compile-map city-roads.geojson -o city-roads.rmp --stats

# Optimize with compiled map (takes 1-5 milliseconds!)
rmpca optimize --cache city.rmp input-roads.geojson -o optimized.gpx

# Test status of jails
rmpca status --health --json | jq .

# Run property-based tests
cargo test --release --tests property_tests
```

### Configuration

Create `~/.config/RouteMaster.toml`:

```toml
[network]
extract_host = "192.168.1.100"
backend_host = "192.168.1.101"
optimizer_host = "192.168.1.102"

[optimization.profiles.truck]
turn_left_penalty = 3.0
turn_right_penalty = 1.0
turn_u_penalty = 8.0

[optimization.profiles.car]
turn_left_penalty = 1.0
turn_right_penalty = 0.0
turn_u_penalty = 5.0

[caching]
cache_dir = "~/.cache/rmpca"

[telemetry]
json_logs = true
```

## Commands

| Command | Description |
|---------|-------------|
| `extract-overture` | Extract Overture Maps road data |
| `extract-osm` | Download & convert OSM data to GeoJSON |
| `compile-map` | Compile GeoJSON to binary graph cache |
| `optimize` | Optimize a GeoJSON route |
| `clean` | Clean/repair GeoJSON |
| `validate` | Validate GeoJSON structure |
| `pipeline` | End-to-end: extract → clean → optimize → export |
| `status` | Show jail/service status |
| `logs` | Tail service logs |

## Performance

### Graph Caching Impact

```
Without cache (parse GeoJSON every time):
- Time: 5-30 seconds per optimization
- CPU: High (parsing, graph construction)

With cache (compile once, load binary):
- Compilation: 5-30 seconds (one-time)
- Loading: 1-5 milliseconds (every run)
- CPU: Minimal (zero-copy deserialization)

Performance gain: 1000x faster for repeated optimizations
```

## Testing

### Property-Based Tests

```bash
# Run all property tests with many random inputs
cargo test --release --tests property_tests

# Run specific property with custom strategy parameters
cargo test prop_eulerian_circuit_is_connected -- --nocapture

# Run with increased test cases for thoroughness
PROPTEST_CASES=10000 cargo test --release --tests property_tests
```

### Unit Tests

```bash
# Run all unit tests
cargo test

# Run specific module tests
cargo test config
cargo test optimizer::types
```

## Development

### Project Structure

The project is organized as:

1. **CLI Layer** (`main.rs`, `commands/`): User-facing commands and argument parsing
2. **Configuration Layer** (`config.rs`): Multi-source configuration system
3. **Optimization Layer** (`optimizer/`): Core algorithms and data structures
4. **Testing Layer** (`tests/`): Property-based and unit tests

### Adding New Commands

1. Create command file in `src/commands/`
2. Implement `pub async fn run(args: Args) -> Result<()>`
3. Add command to `src/commands/mod.rs`
4. Add variant to `Commands` enum in `src/main.rs`
5. Add match arm in `main()`

### Enterprise Features

The codebase includes these production-ready features:

- **Error Handling**: Comprehensive error handling with `anyhow`
- **Logging**: Structured logging with `tracing` crate
- **Async**: Modern async/await with `tokio`
- **Testing**: Property-based testing with `proptest`
- **Serialization**: Zero-copy deserialization with `rkyv`
- **Configuration**: Layered configuration with `figment`
