Can I vibe code Eagle Eye AIR?

Build an open-source enterprise promotions and loyalty engine API in Node.js (TypeScript) using PostgreSQL and Redis.

1. DATA MODELS:
- `customers`: id, external_id, email, phone, created_at.
- `loyalty_accounts`: customer_id, points_balance, tier_level.
- `promotions`: id, name, start_date, end_date, priority, rules_json (conditions), actions_json (discounts).
- `vouchers`: id, code, promotion_id, usage_limit, times_used, status, max_redemptions_per_user.
- `gift_cards`: id, code_hash, initial_balance, current_balance, currency, status.
- `ledger_entries`: id, account_id, amount, transaction_type (earn, redeem, expire), reference_id.

2. CORE API ENDPOINTS:
- `POST /v1/promotions/evaluate`: Accepts a basket payload (items, quantities, prices, customer_id, applied_vouchers). Iterates active promotions ordered by priority, evaluates condition rules (e.g. buy X get Y, cart total threshold, tier qualification), and returns modified line items with calculated discounts sub-100ms.
- `POST /v1/vouchers/redeem`: Atomically validates and increments voucher usage within a Postgres transaction.
- `POST /v1/gift-cards/charge`: Atomic balance reduction on gift cards with Redis locking to prevent double-spending.
- `POST /v1/loyalty/earn`: Event endpoint that adds points based on finalized order revenue.

3. LOGIC & RULES:
- Implement rule evaluation using an extensible engine (e.g., json-rules-engine).
- Multi-promotion handling: enforce mutually exclusive vs stackable promotion tags.
- Handle race conditions in voucher and gift card redemptions using SELECT FOR UPDATE or Redis locks.

4. OUT OF SCOPE:
- POS hardware drivers, physical cash register interfaces, and manual front-end email templates.
