# Compliant Specification

## Executive Summary

This is a compliant spec with [citation1] and [citation2].

## Scientific Foundation

1. Author et al., 2024. Paper Title. [citation3]
2. Another et al., 2024. Another Paper. [citation4]
3. Third et al., 2024. Third Paper. [citation5]

## Requirements

### Functional Requirements

The system MUST provide functionality.
The system SHOULD handle errors gracefully.
The system SHALL be backwards compatible.

### Non-Functional Requirements

Performance MUST be within acceptable limits.

## Acceptance Criteria

### Core Criteria

- [ ] AC-001: First criterion
- [ ] AC-002: Second criterion
- [ ] AC-003: Third criterion
- [ ] AC-004: Fourth criterion
- [ ] AC-005: Fifth criterion
- [ ] AC-006: Sixth criterion
- [ ] AC-007: Seventh criterion
- [ ] AC-008: Eighth criterion
- [ ] AC-009: Ninth criterion
- [ ] AC-010: Tenth criterion

## Code Examples

### Example 1

```rust
fn example_one() {
    println!("Example 1");
}
```

### Example 2

```rust
fn example_two() {
    println!("Example 2");
}
```

### Example 3

```rust
fn example_three() {
    println!("Example 3");
}
```

### Example 4

```rust
fn example_four() {
    println!("Example 4");
}
```

### Example 5

```rust
fn example_five() {
    println!("Example 5");
}
```

## Testing Strategy

Unit tests must cover 95% of the codebase.
Integration tests must validate all endpoints.
Property tests should verify invariants.
E2e tests should test the full workflow.
Mutation tests should validate test quality.
