## Status Transitions

### ADR Status Flow
```
proposed → accepted → deprecated
  ↓          ↓
rejected → proposed
```

### Contract Status Flow
```
draft → review → approved → archived
  ↓      ↓         ↓
deprecated
```

### Feature Status Flow
```
draft → review → approved → implemented
  ↓      ↓       ↓
deprecated
```

### Scenario Status Flow
```
draft → review → ready → executing
  ↓      ↓               ↓       ↓
deprecated              passed  failed
                         ↓       ↓

## Entity Numbering

All entities have unique sequential numbering:

- **ADR**: `ADR-20250120-A1B2C3D4`
- **Contract**: `CTR-20250120-A1B2C3D4`
- **Feature**: `FEAT-20250120-A1B2C3D4`
- **Scenario**: `SC-20250120-A1B2C3D4`

Format: `PREFIX-YYYYMMDD-XXXXXXXX` where XXXXXXXX is 8 random hex chars

---

## Common Patterns

### Pattern: Version-Safe Update
```python
entity = await repo.get_by_id(id)
updated = await repo.update(id, expected_version=entity.version, **updates)
```

### Pattern: Handle Concurrency
```python
from tracertm.core.concurrency import ConcurrencyError

try:
    updated = await repo.update(id, expected_version=version, **updates)
except ConcurrencyError:
    # Fetch fresh and retry
    pass
```

### Pattern: Validate Transition
```python
try:
    updated = await repo.transition_status(id, new_status)
except ValueError:
    # Invalid transition
    pass
```

### Pattern: Project-Scoped Query
```python
items = await repo.list_by_project(project_id=proj_id, status="draft")
```

### Pattern: Always Commit After Writes
```python
result = await repo.create(...)
await db_session.commit()
```

---

## Integration Points

### Uses These Models
- `tracertm.models.adr.ADR`
- `tracertm.models.contract.Contract`
- `tracertm.models.feature.Feature`
- `tracertm.models.scenario.Scenario`

### Uses These Patterns
- ItemRepository CRUD pattern
- TestCaseRepository activity logging
- ProblemRepository status transitions

### Ready for Use In
- Service layer (`tracertm.services.*`)
- API routers (`tracertm.api.routers.*`)
- Business logic
- Dependency injection

---

## Performance Notes

- **Lookups (by ID, by number)**: O(1) - indexed
- **List operations (by project, by feature)**: O(n) - indexed on project_id + status
- **Status transitions**: O(1) - validation only
- **Aggregations (count, average)**: O(n) - group by operations

See [SPECIFICATION_REPOSITORIES.md - Performance Considerations](SPECIFICATION_REPOSITORIES.md#performance-considerations) for optimization tips.

```

### Use in Services
```python
class ADRService:
    def __init__(self, repo: ADRRepository, session: AsyncSession):
        self.repo = repo
        self.session = session
    
    async def create_adr(self, data):
        adr = await self.repo.create(...)
        await self.session.commit()
        return adr
```

2. Run integration tests: `bun run test:api tests/integration/test_specification_repositories.py`
3. Try creating a simple ADR or Feature

### Short Term
1. Create service layer classes for business logic
2. Create API routers for REST endpoints
3. Add request/response schemas

### Future
1. Add full-text search
2. Add audit trail/change tracking
3. Create compliance dashboards
4. Implement scenario execution results
