+# 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
+
+## Verification
+
+| Check | Result |
+|-------|--------|
+| `npm test` | 269 passed, 96 skipped |
+| `npx tsc --noEmit` | 0 errors |
+| `./scripts/verify.sh` | OK |

-# F-190 — Reporting updates from POS sales and returns
+# F-191 — POS terminal and daily cash close reconciliation
 
-Fix reporting capture and refresh so POS sales payments returns pending and completed states update reports.
+Design and implement terminal and daily cash close balancing: card/cash returns and pending payments.
 
 ## Scope
-- POS sales (POST /pos/sales) already emit `reporting_payment_lines` rows on payment — these are verified to capture correctly.
+- POS cashiers can **close their session** (cash close): finalize expected vs actual cash count, handle over/short.
-- POS returns (POST /pos/sales/:id/returns) already emit `reporting_payment_lines` with status=`refund`/`partial_refund` — these are verified to capture correctly.
+- `POST /pos/sessions/:id/close` accepts `actualCashCents` and calculates `varianceCents = actualCashCents - expectedCashCents`. Stores `varianceCents` and `closedAt` on `pos_cash_sessions`.
-- PENDING-payment sales (F-188) when they transition to COMPLETED must emit a payment line to `reporting_payment_lines` so the report shows the sale.
+- Closed sessions can no longer accept new sales or rest-payments.
-- Orders in `PARTIALLY_REFUNDED` and `REFUNDED` must reflect the updated totals in `reporting_payment_lines`.
+- `GET /pos/sessions/:id` returns session summary including total sales, cash received, expected cash, variance.
-- A refresh mechanism for `reporting_payment_lines` for a given order_id exists (for correction scenarios) — or a clear note that manual correction is required.
+- `GET /pos/sessions` lists all sessions (open and closed) for a terminal or store.
-- Any gaps in `expected_cash_cents` calculation for returns are verified and fixed.
+- Admin view: list all cash sessions across terminals with variance. Filter by date range, store, terminal.
+- `expected_cash_cents` is already maintained atomically by sale/rest-payment/return operations.
+- Pending (PENDING state) POS orders from a closed session are still payable via rest-payment from an OPEN session (separate session, same terminal).
 
 ## Out of scope
-- Ecommerce or admin order refunds.
+- Bank deposit slip generation.
-- Automatic reconciliation of discrepancies (manual correction only).
+- Multi-terminal reconciliation in a single close.
+- Automatic variance alerts (out of scope, can be added later).
 
 ## Acceptance
-1. A PENDING sale that transitions to COMPLETED emits exactly one `reporting_payment_lines` row with the correct amount and status.
+1. Cashier can close an open session; session transitions to `CLOSED` and `expected_cash_cents` is frozen.
-2. A fully-returned sale shows a `refund` payment line in reporting with negative amount.
+2. Closing with exact cash (variance=0) is accepted without warning.
-3. A partially-returned sale shows a `partial_refund` payment line in reporting with the partial amount.
+3. Closing with over/short is accepted; variance is stored and visible in admin session list.
-4. Reporting summary totals match the sum of `reporting_payment_lines` for the date range.
+4. No new sales can be started on a closed session.
-5. `verify.sh` green, typecheck green, all tests pass.
+5. Pending orders from a closed session can still be completed via rest-payment from an open session.
+6. `verify.sh` green, typecheck green, all tests pass.
