Backend:
- GET /api/reports/discounts: read-only audit of all OrderDiscount records
Filters: ?from=&to= or ?business_day_id=, ?applied_by=
Returns:
- discounts[]: id, order_id, table_name, applied_by_name, applied_at, discount_type,
discount_value, discount_amount (computed euro value), order_total_before,
item_id (null = whole-order), reason
- total_discount_value: sum of all euro discount amounts
- order_count: unique orders that received a discount
- by_waiter[]: grouped summary (waiter_name, count, total_value)
discount_amount computation: fixed → discount_value directly;
percent → computed from order or item total at query time
Frontend:
- DiscountsLog.jsx: read-only report under Reports → Λειτουργίες → Εκπτώσεις
- Filter bar: range/workday toggle, date range, waiter filter
- 3 stat cards: total discount value, orders with discounts, count of entries
- By-waiter summary table (hidden when only one waiter)
- Full audit table: date, order + table, waiter, type badge (% blue / € amber),
order total before, euro amount discounted in amber, reason
- Totals footer row
- No create/edit/delete — pure audit log

Backend:
- New model: WasteLog (waste_log table) — product, quantity (float), reason, reason_notes,
unit_cost_snapshot (copied at log time from product's effective cost), total_cost (stored),
logged_by, business_day_id
- Cost snapshot: same logic as Phase 2A — breakdown sum first, fallback to cost_simple, null if neither
- New router /api/waste/:
- GET / — list entries (?business_day_id= or ?from=&to=), ordered by logged_at desc
- POST / — log waste; snapshots cost; attaches to open business day automatically
- DELETE /{id} — manager only; only allowed within the same open business day
- GET /summary — totals by reason + by product for a period
- product_performance report: waste_qty + waste_cost added per product from the same period;
products with only waste (no sales) also included
- Migration: CREATE TABLE IF NOT EXISTS waste_log
Frontend:
- WastePage (/waste): fast log form (product picker, quantity, reason chips, notes);
today's entries list below (scoped to active business day); cost shown per entry;
delete button for today's entries; history section behind toggle with date-range picker
- ProductPerformance report: Απόβλητα column showing waste_qty + cost in amber
- Sidebar: Trash2 icon for Αποβλήτα (after Καρτέλες)

- Products: add cost_simple (flat €) and cost_breakdown (JSON line items)
- OrderItems: add unit_cost snapshot written at time of order creation
- Snapshot logic: breakdown sum takes priority over cost_simple; NULL if neither set
- Product schema: serialize/deserialize cost_breakdown as JSON; expose in API
- Product performance report: add trackable_profit, uncosted_revenue, has_gap per product
- Manager UI: cost section in product edit form (simple / detailed toggle with live margin %)
- Products list: show margin % or cost-error badge per product
- Product performance report: profit column + gap warning banner

- New reservations module: model, schema, router (CRUD + status updates + upcoming alerts)
and background task for auto-expiring stale reservations
- Reports: print_products, print_categories, print_tables analytics endpoints
plus meta_products and business_day_summary for workday close/view flow
- printer_service: configurable font sizes/weights, donut/bar chart print layout helpers,
analytics print blocks per printer
- tables/schemas: surfaced color, zone, and other new fields on Table, Product, User, Printer
- demo_seed.py for quick dev DB population; wipe_database.py utility

Backend (reports.py):
- Cache order DB objects to avoid N+1 queries per log entry
- Track seen_order_totals keyed by order_id so reprinting the same
order doesn't inflate the total; returns total_amount pre-computed
Frontend (PrinterHistory.jsx):
- Remove client-side accumulation that caused the same issue; use
total_amount directly from the API response
