Build a modern Manufacturing Resource Planning (MRP) and inventory management web application.

CORE DATA ENGINE & TRANSACTION SAFETY:
- Implement a relational schema (PostgreSQL recommended) using strict foreign keys and transactional state locks.
- System entities:
  * Items (type: Raw Material, Work in Progress, Finished Good; attributes: SKU, Name, Lead Time, Reorder Point, Cost, Sales Price)
  * Bill of Materials (BOM) (parent SKU, child SKU, quantity required, scrap factor %)
  * Inventory Levels (location_id, item_id, quantity_on_hand, quantity_committed, quantity_allocated)
  * Batch / Lot Tracking (lot_number, item_id, manufacture_date, expiry_date, total_qty, remaining_qty)
  * Manufacturing Orders (MO) (status: Draft, Scheduled, In Progress, Done; linked to BOM and Sales Orders)
  * Sales Orders (SO) & Purchase Orders (PO) with multi-line items.
- All inventory adjustments must be append-only audit ledger transactions (InventoryMovement table with timestamps, source_location, destination_location, batch_id, user_id, movement_type). NEVER perform direct UPDATE queries on available stock without logging an audit event.

MRP & BOM EXPLOSION ALGORITHM:
- Build an automatic material requirement calculation: when a Sales Order or Manufacturing Order is placed, recursively explode multi-level BOMs to determine required sub-assemblies and raw materials.
- Implement real-time stock allocation:
  * Check available stock = (on_hand - committed).
  * Automatically mark missing materials as 'Expected' or trigger suggested Purchase Orders.
  * Use FIFO/FEFO (First-Expired, First-Out) logic to auto-assign Lot/Batch numbers to allocated items.

UI & WORKFLOWS:
- Dashboard: Real-time stock status (In Stock, Expected, Committed, Missing) per SKU.
- Manufacturing Order Board: Visual drag-and-drop kanban or list interface showing operational routings (e.g., Cutting -> Assembly -> Packaging).
- Shop Floor Execution View: High-contrast mobile-friendly view for workers to mark operations complete, register actual time spent, scan barcode batch tags, and record scrap.
- Purchase Order Generator: One-click creation of POs aggregated by supplier based on reorder points and open MO demand.

INTEGRATIONS & WEBHOOKS:
- Mock/implement Shopify Webhook Receivers:
  * `orders/create`: Allocate finished goods or trigger Make-to-Order (MTO) Manufacturing Orders.
  * `inventory_levels/connect`: Push physical inventory level updates back to sales channels.
- Implement CSV Import/Export for BOM structure, initial stock counts, and Lot numbers.

OUT OF SCOPE:
- Full double-entry accounting engine (export journal entries to CSV/QuickBooks instead).
- Advanced multi-currency auto-hedging (use fixed daily rate conversions).
- Enterprise multi-tenant SaaS billing (assume single company deployment).
