F-191 — Implementer Evidence

Feature

POS terminal and daily cash close reconciliation.

Changes

1. src/modules/pos/application/receive-rest-payment.ts

Relaxed the terminal/session mismatch check (lines 64-77 new):

• Original check required order.cash_session_id === input.cashSessionId unconditionally.
• New logic (F-191): if the original session is OPEN, still requires exact match. If the original session is CLOSED, allows payment from any OPEN session on the same terminal.
• Preserves security: orders on OPEN sessions must use that session (no cross-session payment).

2. src/modules/pos/api/pos.routes.ts

Added GET /pos/sessions/:id route (after close route, line ~564):

• Returns full session details plus salesCount, salesTotalCents, pendingCount.
• Works for both OPEN and CLOSED sessions.
• POS cashier can see session summary including variance (if closed).

Enhanced GET /pos/sessions admin route with new filters:

• terminalId — filter by terminal
• dateFrom, dateTo — filter by date range (inclusive)
• limit increased to max 100

Existing code (no changes needed)

• CloseCashSessionUseCase — already exists, already stores varianceCents, closedAt
• PgCashSessionRepository.close() — already stores difference_cents
• POST /pos/sessions/:id/close — already exists
• GET /pos/sessions (admin) — already exists, enhanced with filters
• expected_cash_cents maintenance — already atomic via sale/rest-payment/return
