- Many-to-many with TestCase (via association table)

### 5. StepDefinition
**Purpose:** Gherkin step implementations and pattern matching
**Table:** `step_definitions`
**Key Fields:** step_type, pattern, regex_pattern, implementation_code
**Features:** Pattern matching, parameter extraction, usage analytics

**Step Type Values:**

## Usage Pattern Examples

### Creating an ADR
```python
from tracertm.models.specification import ADR, ADRStatus

adr = ADR(
    adr_number="ADR-001",
    project_id="proj-123",
    title="Use microservices architecture",
    status=ADRStatus.ACCEPTED.value,
    context="System needs independent scaling",
    decision="Adopt microservices pattern",
    consequences="Increased operational complexity",
    decision_drivers=["scalability", "independence"],
)
session.add(adr)
session.commit()
```

### Creating a Feature with Scenarios
```python
from tracertm.models.specification import Feature, FeatureStatus, Scenario, ScenarioStatus

feature = Feature(
    feature_number="FEAT-001",
    project_id="proj-123",
    name="User Authentication",
    as_a="user",
    i_want="log in securely",
    so_that="I can access my account",
    status=FeatureStatus.APPROVED.value,
)

scenario = Scenario(
    scenario_number="SCEN-001",
    feature_id=feature.id,
    title="Valid login",
    given_steps=["I am on login page"],
    when_steps=["I enter valid credentials", "I click login"],
    then_steps=["I see dashboard"],
    status=ScenarioStatus.APPROVED.value,
)

session.add(feature)
session.add(scenario)
session.commit()
```

### Querying
```python
from tracertm.models.specification import ADR, ADRStatus

# Find accepted ADRs
accepted = session.query(ADR).filter(
    ADR.project_id == "proj-123",
    ADR.status == ADRStatus.ACCEPTED.value,
    ADR.deleted_at.is_(None)
).all()

# Find active features with scenarios
for feature in session.query(Feature).filter(Feature.deleted_at.is_(None)).all():
    print(f"{feature.name}: {len(feature.scenarios)} scenarios")
```

## Database Schema Overview

### Tables Created
1. **adrs** - Architecture Decision Records
2. **contracts** - Formal Specifications
3. **features** - BDD Features
4. **scenarios** - BDD Scenarios
5. **step_definitions** - Gherkin Step Implementations
6. **scenario_test_case_association** - Many-to-many junction

### Foreign Key Relationships
```
projects ──┬──→ adrs
           ├──→ contracts
           └──→ features
                    │
                    └──→ scenarios
                         │
                         └──→ (many-to-many)
                              test_cases
```

### Cascade Behavior
- Delete project → deletes all ADRs, Contracts, Features
- Delete feature → deletes all Scenarios
- Delete scenario → removes test case associations
