SYSTEM ARCHITECTURE MAP 1. API Layer Path: src/api/ Responsibilities: - HTTP request validation - Authentication middleware - Route-to-service delegation Key dependencies: - src/services/ - src/auth/ - src/schemas/ Risk: - Route handlers contain business logic that should remain inside services. 2. Service Layer Path: src/services/ Responsibilities: - Business rules - Transaction orchestration - Domain-level error handling High-risk dependency: - billing_service.py imports database session state directly. - This makes isolated testing difficult and couples billing logic to SQLAlchemy. 3. Persistence Layer Path: src/repositories/ Responsibilities: - Database reads and writes - Query composition - Entity persistence Contract issue: - UserRepository.get() returns None. - InvoiceRepository.get() raises EntityNotFound. - Callers must currently handle inconsistent failure behavior. TECHNICAL DEBT P0 — Circular dependency src/services/orders.py -> src/services/inventory.py -> src/events/order_events.py -> src/services/orders.py Impact: - Complicates module initialization - Blocks isolated service tests - Increases the risk of runtime import failures Recommended change: - Extract InventoryReservation into src/domain/inventory/ - Publish an OrderCreated event through an interface - Move event-handler registration to the application bootstrap layer REFACTORING RISKS 1. API compatibility Risk: Renaming Order.status values could break mobile clients. Control: Preserve serialized enum values and add contract tests. 2. Transaction boundaries Risk: Moving payment logic could create partial order writes. Control: Wrap order creation, payment authorization, and inventory reservation in an explicit unit-of-work boundary. 3. Background jobs Risk: Existing workers import service functions directly. Control: Introduce compatibility adapters before changing service signatures. Recommended sequence: Add characterization tests around current API behavior. Normalize repository error contracts. Break the circular service dependency. Introduce a unit-of-work abstraction. Refactor route-level business logic. Run API, integration, migration, and worker regression suites.

PLAN Constraints: - Preserve public function names and parameters - Preserve return values and exception behavior - Do not change database schema - Keep existing API imports valid Steps: 1. Capture current behavior with tests. 2. Extract duplicated validation logic. 3. Separate data access from transformation logic. 4. Replace nested conditionals with guard clauses. 5. Run unit and integration tests. 6. Compare public signatures before and after. Validation report: $ pytest tests/unit/test_pricing.py tests/integration/test_checkout.py -q 42 passed in 3.81s Public API comparison: - calculate_total name: unchanged - Parameter order: unchanged - Default discount value: unchanged - Return type: Decimal, unchanged - Existing exception messages: unchanged Impact analysis: Validation is now independently testable. Calculation behavior remains unchanged. Cyclomatic complexity decreased. No database, schema, route, or client changes are required. Rollback can be completed by reverting a single module.

Run three fixed-seed training trials. Report mean performance and 95% confidence intervals. Compare reproduced metrics with the paper’s reported values. Run an ablation without the paper’s primary architectural change. Document hardware, runtime, package versions, and checkpoint selection. Mark the result as replicated only when the reported score falls inside the reproduced confidence interval.
