-- ------------------------------------------------------------
-- REVIEW DRAFT: prc_order + rename ext -> prc_order_ext
-- Confirm schema before app code changes.
--
-- Target model:
--   prc_billing_task --transfer_no--> TAB_ORDER
--   -> upsert prc_order (UK transfer_no), delete task by transfer_no
--   -> prc_order 1:1 prc_order_ext (PK/FK = order_id)
--   -> prc_order_bill keeps bill_id; adds order_id + transfer_no
--
-- Naming:
--   order_id = BMS UUID PK (same rule as bill_id)
--   old prc_order_bill_ext renamed to prc_order_ext
--   columns moved to prc_order are DROPped from prc_order_ext
-- ------------------------------------------------------------

-- ============================================================
-- Review checklist
-- ------------------------------------------------------------
-- prc_order: identity + L/W/H + weights + staff + billing status
-- prc_order_ext: leftover TAB_ORDER only (no dup of moved cols)
-- prc_order_bill: pricing result; +order_id; still has bill_id
-- Dropped from ext (now on prc_order):
--   product_floor_code, order_status, pickup_date, dimensional_weight_factor
