Can I vibe code SalesWarp?

1. OVERVIEW: Build a Distributed Order Management (DOM) service in Node.js (TypeScript) using Express, PostgreSQL, and BullMQ with Redis. The system centralizes inventory allocation, listens to sales channel order webhooks, executes order routing rules across multiple locations, and syncs updated stock levels back to channels.

2. DATA MODEL:
- Location (id, name, zip_code, priority, is_active)
- SKU (id, code, title, weight_oz)
- InventoryLevel (id, sku_id, location_id, total_on_hand, reserved, available GENERATED)
- Order (id, channel, external_id, status, customer_info, shipping_address, created_at)
- OrderLineItem (id, order_id, sku_id, quantity, status)
- FulfillmentOrder (id, order_id, location_id, tracking_number, status)

3. CORE LOGIC & ROUTING ENGINE:
- Expose POST /webhooks/orders to receive orders from Shopify or WooCommerce.
- Order Routing Pipeline: Upon receipt, execute routing in a database transaction using SELECT ... FOR UPDATE to lock InventoryLevel rows:
  a) Single Location Match: Find the nearest active location with full inventory available for all line items.
  b) Split Shipment Fallback: If no single location has full inventory, split order line items across locations to minimize fulfillment packages.
  c) Decrement 'available' count by increasing 'reserved' count atomically.
- Generate FulfillmentOrder records with designated locations.

4. SYNC & FAILURE MODES:
- Use BullMQ queue ('stock-sync-queue') for outbound updates to channels whenever inventory changes.
- Implement exponential backoff (5 retries) for failed external sync calls.
- Webhook processing must be strictly idempotent using external_id deduplication keys in Redis.
- If routing fails due to zero inventory, set Order status to 'unfulfillable_backorder' and trigger an alert.

5. OUT OF SCOPE:
- EDI file generation, legacy ERP connectors, manual label printing integration, and native accounting GL modules.
