+# POS-003 — Architect
+
+## Feature
+POS module skeleton: domain + repos + application use cases.
+
+## Design
+Domain layer: PosStore, PosTerminal, PosCashSession types + all errors. Ports: PosStoreRepository, PosTerminalRepository, PosCashSessionRepository interfaces.
+Infrastructure: PgStoreRepository, PgTerminalRepository, PgPaymentMethodRepository, PgCashSessionRepository.
+Application: ListStores, ListTerminals, GetPosConfig, OpenCashSession, CloseCashSession use cases.
+Tests: unit tests for store listing + cash session open/close.
+Wired into build-app.ts (repos in deps, no routes yet — covered by POS-004).

+# POS-003 — Documenter evidence
+
+## Scope of documentation change
+POS-003 creates the POS module skeleton. No documentation changes needed — POS-004 (routes) and subsequent tickets will document the API.

+
+## What
+POS module skeleton: domain + repos + application use cases. No routes (POS-004 covers that).
+
+## Files
+- `src/modules/pos/domain/errors.ts` — PosError, StoreNotFound, TerminalNotFound, CashSessionNotFound, CashSessionAlreadyOpen, CashSessionNotOpen, TerminalNotBound, TerminalDisabled
+- `src/modules/pos/domain/store.ts` — PosStore, ListStoresOptions
+- `src/modules/pos/domain/terminal.ts` — PosTerminal, TerminalStatus, InterfaceMode, ListTerminalsOptions
+- `src/modules/pos/domain/cash-session.ts` — PosCashSession, CashSessionStatus, OpenCashSessionInput, CloseCashSessionInput
+- `src/modules/pos/domain/ports.ts` — PosStoreRepository, PosTerminalRepository, PosCashSessionRepository interfaces
+- `src/modules/pos/infrastructure/pg-store-repository.ts` — PgStoreRepository (findById, list)
+- `src/modules/pos/infrastructure/pg-terminal-repository.ts` — PgTerminalRepository (findById, findByBindingCode, list, updateLastSeen, bind)
+- `src/modules/pos/infrastructure/pg-payment-method-repository.ts` — PgPaymentMethodRepository (listByStore)
+- `src/modules/pos/infrastructure/pg-cash-session-repository.ts` — PgCashSessionRepository (findById, findOpenByTerminal, open, close, listByStore)
+- `src/modules/pos/application/list-stores.ts` — ListStoresUseCase
+- `src/modules/pos/application/list-terminals.ts` — ListTerminalsUseCase
+- `src/modules/pos/application/get-pos-config.ts` — GetPosConfigUseCase
+- `src/modules/pos/application/open-cash-session.ts` — OpenCashSessionUseCase (validates terminal bound+active, rejects duplicate sessions)
+- `src/modules/pos/application/close-cash-session.ts` — CloseCashSessionUseCase
+- `src/modules/pos/tests/store-repository.test.ts` — 2 tests
+- `src/modules/pos/tests/cash-session.test.ts` — 6 tests
+- `src/app/build-app.ts` — wired POS repos
+
+## Verification
+- `npm run build` → 0 TypeScript errors.
+- `npm test -- --run src/modules/pos/tests/` → 8 passed.
+- `check-module-boundaries.mjs src` → 0 NEW violations.
+- `./scripts/verify.sh` → green.
+
+## AC traceability
+| AC | Estado | Evidencia |
+|----|--------|-----------|
+| AC1 domain types | ✅ | PosStore, PosTerminal, PosCashSession + errors |
+| AC2 repos | ✅ | 4 Pg*Repository implementations |
+| AC3 use cases | ✅ | 5 use cases (list-stores, list-terminals, get-pos-config, open, close) |
+| AC4 tests | ✅ | 8 unit tests covering core scenarios |
+| AC5 build-app wired | ✅ | POS repos added to build-app.ts |
+| AC6 scope out | ✅ | No routes (POS-004) |
