## 2. Key Critical Flow Assertions Breakdown

### 2.1 Concurrency & Anti-Double-Sale Verification
- **Test**: `test_unit_cannot_be_sold_twice_even_under_concurrent_race_condition`
- **Mechanism**: `PosCheckoutService` utilizes `lockForUpdate()` within an atomic transaction.
- **Verification**: Verified that attempting to checkout an already sold unit throws an exception and halts the transaction without double-charging or corrupting inventory counts.

### 2.2 Complete Supply Chain End-to-End Traceability
- **Test**: `test_complete_manufacturing_to_retail_sale_lifecycle`
- **Steps Verified**:
  1. Product created with 5% GST (`selling_price: 250.00`).
  2. Batch created (`PA-BT-E2E-999`) with actual quantity 1.
  3. Physical unit generated with unique serial `PA-P010-000001` and 32-char hex QR token.
  4. QA verification performed via keyboard-wedge scan, advancing unit to `VERIF_VERIFIED`.
  5. Central warehouse intake executed, advancing unit to `STATUS_IN_WAREHOUSE` at `PA-WH-E2E-01`.
  6. Inter-store stock transfer created and dispatched, transitioning unit to `STATUS_IN_TRANSIT`.
  7. Store receiving confirmed intact, clearing unit into `STATUS_IN_STORE` at Flagship Store.
  8. Cashier scanned unit via `/pos/scan-unit`, cart computed subtotal (250) + tax (12.5) = 262.5.
  9. POS checkout committed, advancing unit to `STATUS_SOLD` with `sold_at` and `invoice_id`.
  10. Public QR verification endpoint queried at `/scan/{token}`, validating authentic certificate while confirming zero disclosure of warehouse names, store names, or cashier identities.

### 2.3 Store Isolation & Anti-IDOR Security
- **Tests**:
  - `test_store_admin_cannot_access_unassigned_store_via_url_tampering`
  - `test_store_admin_cannot_view_another_store_via_query_tampering`
  - `test_cashier_is_strictly_blocked_from_financial_reports`
- **Result**: Store Admins receive HTTP 403 or scoped results matching strictly their assigned store ID. Cashiers querying `/reports` or `/reports/export` receive HTTP 403 Forbidden.

### 2.4 Customer Returns & Quality Quarantine
- **Tests**:
  - `test_cashier_can_initiate_sales_return_request`
  - `test_cashier_cannot_approve_refund` (Returns 403)
  - `test_store_admin_can_approve_restock_refund_and_reintegrate_unit` (`STATUS_IN_STORE`)
  - `test_damaged_returned_unit_transitions_to_quarantine_never_saleable` (`STATUS_DAMAGED`)
