## 📊 Template Features

### Core Capabilities

1. **Hermetic Testing**
   - Isolated test environments
   - Deterministic execution with fixed seeds
   - Security policy enforcement
   - Resource limit testing

2. **Container Integration**
   - PostgreSQL database testing
   - Redis cache testing
   - Testcontainers integration
   - Automatic cleanup

3. **Swarm Coordination**
   - Multi-agent orchestration
   - Parallel task execution
   - Agent metrics and monitoring
   - Error recovery mechanisms

4. **CI/CD Integration**
   - GitHub Actions workflow
   - Security audits (cargo-audit, cargo-deny)
   - Performance benchmarks
   - Production readiness checks

5. **Performance Testing**
   - Criterion benchmarks
   - Command complexity testing
   - Parallel execution testing
   - Security policy overhead analysis

## 🎯 Key Design Decisions

### 1. YAML Frontmatter Format

All templates use YAML frontmatter following ggen conventions:

```yaml
---
to: "{{ project_name }}/tests/test_file.rs"
vars:
  project_name: "my-project"
  test_name: "integration_test"
  determinism: 42
---
```

### 2. Deterministic Testing

Every template includes determinism seed support for reproducible tests:

```rust
let policy = Policy {
    determinism: Some(clnrm::policy::DeterminismConfig {
        seed: {{ determinism }},
        ..Default::default()
    }),
    ..Default::default()
};
```

### 3. Production-Ready Code

- **No `.unwrap()` or `.expect()`** - All error handling uses `?` operator
- **Proper error types** - Uses `anyhow::Result` for flexible error handling
- **Resource cleanup** - Automatic container cleanup with Drop
- **Security by default** - Templates include security policy examples

### 4. Modular Design

Templates can be used individually or combined:

```bash
# Use single template
ggen template generate cleanroom/test-environment.tmpl

# Use multiple templates
ggen template generate cleanroom/postgres-container.tmpl
ggen template generate cleanroom/redis-container.tmpl
```

## 📈 Usage Statistics

### Template Variables

| Variable | Used In | Description |
|----------|---------|-------------|
| `project_name` | All | Project/crate name |
| `test_name` | test-environment | Test suite name |
| `test_suite_name` | postgres, redis, swarm | Specific test suite name |
| `determinism` | All | Determinism seed for reproducibility |
| `db_name` | postgres | Database name |
| `db_user` | postgres | Database username |
| `db_password` | postgres | Database password |
| `swarm_size` | swarm-coordinator | Number of agents |
| `rust_version` | ci-pipeline | Rust toolchain version |

cd my-cleanroom-app

# Add dependencies
cargo add clnrm testcontainers testcontainers-modules tokio anyhow
cargo add --dev criterion

# Generate all templates
ggen template generate cleanroom/test-environment.tmpl --var project_name=my-cleanroom-app
ggen template generate cleanroom/postgres-container.tmpl --var project_name=my-cleanroom-app
ggen template generate cleanroom/redis-container.tmpl --var project_name=my-cleanroom-app
ggen template generate cleanroom/swarm-coordinator.tmpl --var project_name=my-cleanroom-app
ggen template generate cleanroom/ci-pipeline.tmpl --var project_name=my-cleanroom-app
ggen template generate cleanroom/benchmark-suite.tmpl --var project_name=my-cleanroom-app

# Run tests
cargo test

# Run benchmarks
cargo bench
```

### Individual Template Usage

```bash
# Basic testing
