Can I vibe code Appath?

Build a multi-channel inventory and order management system in Next.js (App Router) with TypeScript, Tailwind CSS, PostgreSQL (via Prisma), and Redis (via BullMQ).

1. DATA MODEL:
- Product: id, sku (unique), title, total_stock, reserved_stock, price.
- Channel: id, platform (SHOPIFY, ECOMMERCE_REST, CUSTOM), api_credentials (encrypted JSON), sync_enabled.
- ChannelVariantMap: id, product_id, channel_id, external_variant_id, external_sku.
- Order: id, external_order_id, channel_id, status (PENDING, PAID, SHIPPED, CANCELLED), customer_email, total_price, shipping_address (JSON).
- OrderItem: id, order_id, product_id, quantity, unit_price.
- InventoryLog: id, product_id, change_amount, reason, reference_id, created_at.

2. CORE FUNCTIONALITY:
- Central SKU Inventory: Master stock count stored in Postgres. Redis atomicity locks during stock deduction.
- Multi-Channel Sync Engine: BullMQ job worker that triggers on local inventory changes, broadcasting updated available stock (total_stock - reserved_stock) to connected channels via background workers.
- Webhook Ingestion: Dynamic endpoints `/api/webhooks/[channel]` to ingest incoming orders, create local Order records, mark inventory as reserved, and trigger background stock updates to all other connected channels.
- Order Table UI: Server-rendered dashboard displaying orders across all channels with filtering by status, channel, and date range. Include bulk actions to mark as shipped or print packing slips.
- Shipping Label Integration: Basic integration with EasyPost API to create shipments, calculate rate options, and purchase/generate PDF shipping labels.

3. FAILURE MODES & EDGE CASES:
- Race Conditions: Use Redis atomic decrement operations when multiple channels place orders simultaneously for the last remaining unit.
- Rate Limits: Wrap external API sync calls in exponential backoff retry logic (3 attempts max).
- Idempotency: Deduplicate webhook payloads using `external_order_id` as an idempotency key to prevent double-deduction.

4. OUT OF SCOPE:
- Amazon SP-API complex OAuth/LWA integrations.
- Matrix/variant generation with dynamic attributes.
- Native accounting and ledger management.
