POS-003 — Implementer evidence

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
