3. Design State Machine

enum DesignStatus {
  DRAFT = 'draft',
  PROCESSING = 'processing',      // AI generating / upscaling
  REVIEW_PENDING = 'review_pending', // Waiting QC/IP check
  REVIEW_REJECTED = 'review_rejected',
  APPROVED = 'approved',
  PUBLISHED = 'published',        // Listed on channels
  PAUSED = 'paused',              // Temporarily unlisted
  ARCHIVED = 'archived',
  DMCA_TAKEDOWN = 'dmca_takedown' // IP violation
}

interface DesignStateTransition {
  from: DesignStatus;
  to: DesignStatus;
  trigger: string;
  guard?: string;
}

const transitions: DesignStateTransition[] = [
  { from: 'draft', to: 'processing', trigger: 'submit_for_generation' },
  { from: 'processing', to: 'review_pending', trigger: 'generation_complete' },
  { from: 'review_pending', to: 'approved', trigger: 'qc_passed', guard: 'ip_check_clean' },

7. Tổng kết

• POD Lifecycle — Từ ý tưởng đến sản phẩm bán chỉ trong phút (AI) thay vì tháng (traditional)

• AI-assisted workflow — Giảm 80% thời gian design, auto QC, auto listing

• Design State Machine — draft → processing → review → approved → published

• Order workflow — Split orders, parallel production, consolidated shipping

• Print methods — DTG/DTF/Sublimation mỗi loại có technical requirements riêng

• KPIs — Conversion ≥ 2.5%, defect ≤ 2%, production ≤ 3 days
