- Validating rule completeness and consistency

## Business Rule Categories

### Structural Rules (Facts)

Define the nature of things and relationships:

```yaml
structural_rules:
  definition: "Rules that define terms, concepts, and their relationships"

  types:
    terms:
      description: "Definitions of business concepts"
      example: "A 'Premium Customer' is a customer who has spent more than $10,000 in the last 12 months"

    facts:
      description: "Assertions about the business domain"
      example: "Each Order must have exactly one Customer"

    relationships:
      description: "How concepts relate to each other"
      example: "A Customer may have zero or more Orders"

  documentation_template:
    term: "{Term} is defined as {definition}"
    fact: "{Subject} {verb} {object}"
    relationship: "{Entity A} {cardinality} {Entity B}"
```

### Derivation Rules (Computations)

Calculate or derive values from other data:

```yaml
derivation_rules:
  definition: "Rules that compute values from other information"

  types:
    calculations:
      description: "Mathematical computations"
      example: "Order Total = Sum of (Line Item Quantity × Unit Price)"

    aggregations:
      description: "Summary calculations across sets"
      example: "Monthly Reven
