   ├─ Key Fields: title, contract_type, status
   ├─ Features:
   │  ├─ Formal specs (preconditions, postconditions, invariants)
   │  ├─ State machines (states, transitions)
   │  ├─ Executable specs (code, language, verification)
   │  └─ Governance (approval tracking, verification results)
   └─ Indexes: 3 (project+status, project+type, project+number)

3. Feature (BDD Feature)
   ├─ Table: features
   ├─ Unique ID: feature_number (per project)
   ├─ Parent: project_id
   ├─ Key Fields: name, description, as_a, i_want, so_that
   ├─ Features:
   │  ├─ User story format
   │  ├─ Background steps
   │  ├─ Traceability (requirements, ADRs)
   │  ├─ BDD tags
   │  └─ Relationship to Scenarios (1:N)
   └─ Indexes: 2 (project+status, project+number)

4. Scenario (BDD Scenario)
   ├─ Table: scenarios
   ├─ Unique ID: scenario_number

   │  ├─ Requirement traceability
   │  ├─ Relationship to TestCases (N:N via association table)
   │  └─ Full gherkin_text storage
   └─ Indexes: 3 (feature+status, scenario_number, status)
                + 1 on association table

5. StepDefinition (Gherkin Implementation)

   ├─ Key Fields: step_type, pattern, regex_pattern
   ├─ Features:
   │  ├─ Step type classification (Given, When, Then, And, But)
   │  ├─ Pattern matching (text + regex)
   │  ├─ Implementation tracking (path, code)

ENUMS CREATED
================================================================================

ADRStatus: proposed, accepted, deprecated, superseded, rejected

ContractType: interface, component, service, system, integration, database
ContractStatus: draft, review, approved, deprecated, archived

FeatureStatus: draft, review, approved, deprecated, archived

ScenarioStatus: draft, review, approved, deprecated, archived

ENTERPRISE FEATURES
================================================================================

✓ Timestamps (created_at, updated_at)
✓ Optimistic Locking (version field)
✓ Soft Delete (deleted_at field)
✓ Flexible Metadata (JSON field with alias)
✓ UUID Primary Keys (auto-generated)
✓ Foreign Key Constraints (with CASCADE)
✓ Strategic Indexes (15+ total)
✓ Relationships (Feature→Scenario, Scenario↔TestCase)
✓ Type Hints (Mapped, SQLAlchemy 2.0)
✓ Comprehensive Docstrings

================================================================================
DATABASE SCHEMA SUMMARY
================================================================================

5 Tables:
  - adrs (project_id → projects.id)
  - contracts (project_id → projects.id)
  - features (project_id → projects.id)
  - scenarios (feature_id → features.id)
  - step_definitions (standalone)

1 Association Table:
  - scenario_test_case_association (N:N junction)

Cascade Behavior:
  ✓ Deleting a project cascades to all ADRs, Contracts, Features
  ✓ Deleting a feature cascades to all Scenarios
  ✓ Deleting a scenario removes association with test cases

================================================================================
READY FOR
================================================================================

✓ Migration creation (bun run migrate)
✓ Import in models/__init__.py
✓ Schema definition (Pydantic)
✓ Repository pattern (data access)
✓ Router creation (tRPC endpoints)
✓ Testing (unit & integration)

================================================================================
NEXT STEPS
================================================================================

1. Create migration file:
   - Run: bun run migrate
   - Creates tables and indexes
   
2. Update __init__.py:
   - Import models from specification.py
   - Add to __all__ exports

3. Create schemas:
   - src/tracertm/schemas/specification.py
   - Pydantic models for API validation

4. Create repositories:
   - src/tracertm/repositories/adr_repository.py
   - src/tracertm/repositories/contract_repository.py
   - (etc. for each model)

5. Create routers:
   - src/tracertm/api/routers/adrs.py
   - src/tracertm/api/routers/contracts.py
   - (etc. for each model)

6. Add tests:
   - tests/unit/models/test_specification.py
   - tests/api/test_adr_router.py
   - (etc.)
