Phase 4: Inventory, Expenses, and Financial Reports Verification Report

Phase Goal: Staff can track all network hardware through its full lifecycle as an immutable movement ledger; expenses are recorded and post to the ledger automatically; and the accounting module can produce a verified Trial Balance, Income Statement, and Balance Sheet from journal entry history alone. Verified: 2026-03-05T12:00:00Z Status: passed Re-verification: No -- initial verification

Goal Achievement

Observable Truths

# Truth Status Evidence
1 Staff can register hardware and record movements as immutable events; stock levels derived from movement history VERIFIED InventoryService (429 lines) has registerItem, recordMovement with 5 movement types, getStockLevels derived via aggregation. StockMovement schema has no updatedAt (immutable). No mutable quantity column exists. 13 tests cover registration, movements, stock derivation.
2 Asset assigned to subscriber shows full location history VERIFIED AssetService (449 lines) has getAssetHistory returning chronological timeline with resolved subscriber/technician/warehouse names via batch Map lookup. API at GET /api/inventory/items/[id]/history wired to AssetService. 11 tests include full lifecycle test (RECEIVED to ISSUED to tech to RETURNED to ISSUED to sub to RETURNED to DISPOSED).
3 Expense records with amount/date/category/vendor auto-create double-entry JE with audit trail VERIFIED Expense model has amount (Decimal), expenseDate, categoryId, vendorId, createdById, journalEntryId fields. ExpenseService.postExpense creates balanced JE via JournalEntryService.createEntry with DR expense account (from category.accountCode) and CR cash/bank (from paymentMethod). AuditTrailService (169 lines) traces JE to creator, timestamp, and source referenceType/referenceId. 15 expense tests + 9 audit trail tests.
4 Income Statement for date range and Balance Sheet as of date, derived from JE lines VERIFIED FinancialReportService (557 lines) getIncomeStatement queries JE lines by REVENUE/EXPENSE account types within date range. getBalanceSheet queries JE lines for ASSET/LIABILITY/EQUITY up to asOfDate, computes Net Income inline. Both use journalEntryLine.groupBy with POSTED status filter. API routes wired to service. 16 tests verify correct amounts and date filtering.
5 Trial Balance with debits equal credits -- self-verifying VERIFIED FinancialReportService.getTrialBalance computes totalDebits and totalCredits from JE lines, returns isBalanced = equalsInCents(totalDebits, totalCredits). Tests explicitly assert isBalanced === true and totalDebits.equals(totalCredits). Empty tenant also verified balanced with zero totals.

Anti-Patterns Found

No TODO, FIXME, placeholder, or stub patterns found in any phase 4 service or API route file.

Human Verification Required

1. Stock Level Derivation Accuracy

Test: Register batch items, perform mixed movements (RECEIVED, ISSUED, RETURNED, DISPOSED), then check /api/inventory/stock-levels Expected: Stock levels match expected quantities at each location Why human: Complex aggregation logic; manual spot-check against real DB confirms correctness

2. Full Asset Lifecycle Timeline

Test: Create serialized item, assign to technician, return, assign to subscriber, return, dispose. View /api/inventory/items/{id}/history Expected: Chronological timeline with resolved names Why human: Name resolution depends on actual subscriber/user records

3. Financial Reports Cross-Consistency

Test: Create various transactions, generate all 3 reports Expected: Trial Balance debits = credits; Income Statement net income matches Balance Sheet net income line Why human: Cross-report consistency needs human verification with known data

Gaps Summary

No gaps found. All 5 observable truths verified at all three levels (existence, substantive implementation, wiring). All 15 requirements satisfied. No stub patterns found. 64 integration tests across 5 test files cover all critical behaviors.
