## Statistics

- **Total Files**: 15 (excluding git/target)
- **Total Lines of Code**: 357
- **Modules**: 4 (widgets, layouts, canvas, bindings)
- **Examples**: 2
- **Tests**: 2 (unit + integration)
- **Benchmarks**: 1

## Dependencies Configured

### Production
- `ratatui = "0.28"` - TUI framework
- `fusabi-vm = "0.16"` - F# scripting runtime
- `serde = "1.0"` - Serialization
- `anyhow = "1.0"` - Error handling
- `crossterm = "0.28"` - Terminal abstraction
- `tracing = "0.1"` - Logging

### Development
- `tempfile = "3.8"` - Test isolation
- `criterion = "0.5"` - Benchmarking

## Build Status

✅ **Compiles successfully**
```bash
cargo build
# Finished `dev` profile [unoptimized + debuginfo] target(s)
```

✅ **All tests pass**
```bash
cargo test
# test result: ok. 2 passed; 0 failed; 0 ignored
```

✅ **Documentation builds**
```bash
cargo doc
# 4 doc-tests pass
```

## Warnings

Minor warnings present (expected for scaffold):
- Unused imports in stub modules
- Unused fields in placeholder structs

These will be resolved during implementation phase.

## Git Status

- ✅ Repository initialized
- ✅ .gitignore configured
- ⏳ Initial commit pending
- ⏳ Remote not configured

## Next Steps

### Phase 1: Widget Implementation
1. Extract widget builders from `hibana/src/top.rs`
2. Implement List, Table, Gauge widgets
3. Add comprehensive tests

### Phase 2: Layout System
1. Implement constraint solver
2. Add layout computation logic
3. Test with various constraint combinations

### Phase 3: Canvas Rendering
1. Extract canvas utilities from Hibana
2. Implement shape drawing primitives
3. Add coordinate mapping

### Phase 4: Fusabi Integration
1. Implement native function wrappers
2. Add F# type marshaling
3. Register with Fusabi VM

### Phase 5: Documentation & Examples
1. Write comprehensive examples
2. Document all public APIs
3. Create usage tutorials

## Commands Reference

```bash
# Build
cargo build

# Run tests
cargo test

# Run benchmarks
cargo bench

# Generate documentation
cargo doc --open

# Run examples
cargo run --example simple_list
cargo run --example layout_demo

# Check code
cargo check
cargo clippy
cargo fmt
```

## Key Features of Scaffold

1. **Modular Structure**: Clean separation of concerns
2. **Type Safety**: Strong typing with Result-based error handling
3. **Documentation**: Inline docs and architecture guide
4. **Testing**: Integration test framework ready
5. **Benchmarking**: Criterion configured for performance tests
6. **Examples**: Placeholder examples for future demos
7. **Licensing**: Dual MIT/Apache-2.0 license

## Design Decisions

1. **Library Crate**: `cargo new --lib` for reusability
2. **Module Organization**: Four core modules (widgets, layouts, canvas, bindings)
3. **Error Handling**: `anyhow::Result<T>` for flexibility
4. **Builder Pattern**: For widget construction
5. **Trait-Based**: Common interfaces via `Widget` and `WidgetBuilder` traits
