1. Immutable Stock Movements & SQL FIFO
Stock balances in Deku are derived directly from immutable `stock_movements` records (`in` / `out`), priced using FIFO per `(item_id, warehouse_id)` so reported closing stock never drifts from movement history.
2. Multi-Warehouse Scope
Organisations can create multiple warehouses and record opening balances or manual adjustments per warehouse. Automated invoice issuance deducts tracked goods from the organisation's designated default warehouse.
