 ## Current Build Phase
 > Update this line as you progress:
 > Phase 1: Local Backend — [x] Complete. Smoke tested: health, auth, products, tables, orders, printer routing all working.
-> Phase 2: Waiter PWA — [x] Complete. Built with React+Vite+PWA: Login/PIN, TableList, TableDetail, AddItems, Offline pages; all components wired to backend API; dark theme; vite build passes clean.
+> Phase 2: Waiter PWA — [x] Complete. Smoke tested end-to-end: login, table list, open order, add items, select/pay with confirmation, close order. See "Phase 2 Known Issues & Fixes" below.
 > Phase 3: Manager Dashboard — [ ] Not Started
 > Phase 4: Cloud Backend — [ ] Not Started
 > Phase 5: Sysadmin Panel — [ ] Not Started
 
+## Phase 2 Known Issues & Fixes Applied
+- `OrderItemOut` schema now includes `product { id, name }` via `ProductNameOut` — required for item names to show correctly in the PWA.
+- `OrderOut` schema now includes `waiters: List[OrderWaiterOut]` — required for `isMyOrder` check on the frontend.
+- Close order button is enabled when there are zero active items (not just when all are paid) — allows closing an empty order.
+- Printing silently skips items with no `printer_zone_id` — **expected**. Printer zones are assigned in Phase 3 (Manager Dashboard). No code change needed.
+- `selected_options` and `removed_ingredients` on `OrderItemInput` accept `List[dict]` from the PWA (name+price_delta objects and name strings respectively), stored as JSON in the DB. The printer service reads them as raw JSON — modifier names print correctly.
+
+## Phase 2 Dev Data (seeded manually, not in seed.py)
+- Tables 1–6 exist (table 1 was from Phase 1 smoke test)
+- Category "food" (id=1) exists from Phase 1 smoke test — contains product "arakas"
+- Categories: Ποτά, Σαλάτες, Κυρίως — 3 products each
+- No printer zones assigned to any product yet
