This commit implements Phase 3 of the Wan2.1 PWA, closing all critical integration gaps between frontend, backend, database, and Replicate API. ## Backend Integration ✅ ### Database Writes - Create generation records BEFORE calling Replicate - Store job_id for tracking Replicate predictions - Track progress, status, and completion timestamps - Save video URLs and error messages ### Credit System - Atomic credit deduction using database function deduct_credits() - Automatic refunds on generation failures via refund_credits() - Complete audit trail in credit_transactions table - Transaction logging for all credit operations ### Webhook Handler - Created /api/webhooks/replicate endpoint - HMAC signature verification for security - Automatic status updates from Replicate push notifications - Maps Replicate statuses to application statuses - Triggers refunds for failed generations ### Updated Generation Flow 1. Check user credits before starting 2. Create generation record (status: queued) 3. Start Replicate job and get job_id 4. Update record with job_id (status: processing) 5. Deduct credits atomically 6. Webhook updates status when complete 7. Polling fallback if webhook fails ## Frontend Enhancements ✅ ### Error Handling - Added sonner for beautiful toast notifications - Success/error/loading states with retry actions - User-friendly error messages - Providers component wraps app with Toaster ### Form Validation - Zod schemas for T2V and I2V inputs - Prompt length validation (10-500 chars) - Model and resolution validation - Credit cost calculator ### Credit Management - useCredits hook for real-time credit fetching - Optimistic updates on generation start - Credit refresh functionality - Loading and error states ### Image Upload - Drag-and-drop ImageUpload component - Client-side validation (file type, size) - Image preview functionality - Max 10MB size limit with user feedback - Ready for I2V integration ### Settings Page - Basic settings page structure - Placeholders for Profile, Billing, API Keys - Ready for Phase 4 enhancements ## Database Changes ✅ ### New Migration: 002_credit_system.sql - credit_transactions table with audit trail - deduct_credits() function for atomic operations - add_credits() function for purchases/bonuses - refund_credits() function for failed generations - Added job_id, progress, error_message columns to generations ## Documentation ✅ ### PHASE_3_IMPLEMENTATION.md - Complete implementation guide - Testing checklist (backend, frontend, E2E) - Deployment steps with webhook registration - Known issues and limitations - Metrics to monitor - Phase 4 roadmap ## Files Changed ### Backend (4 files) - apps/api/main.py - Added webhooks router - apps/api/routes/generation.py - Complete rewrite with DB integration - apps/api/routes/webhooks.py - NEW webhook handler - packages/db/migrations/002_credit_system.sql - NEW credit system ### Frontend (7 files) - apps/web/package.json - Added sonner - apps/web/src/app/layout.tsx - Added Providers wrapper - apps/web/src/app/dashboard/settings/page.tsx - NEW settings page - apps/web/src/components/providers.tsx - NEW toast provider - apps/web/src/components/generation/image-upload.tsx - NEW upload component - apps/web/src/lib/hooks/use-credits.ts - NEW credit management hook - apps/web/src/lib/validation/generation.ts - NEW Zod schemas ### Documentation (1 file) - PHASE_3_IMPLEMENTATION.md - NEW comprehensive guide ## Testing Required ### Backend - [ ] Database writes on generation start - [ ] Credit deduction accuracy - [ ] Webhook updates from Replicate - [ ] Refunds on failures ### Frontend - [ ] Toast notifications - [ ] Form validation - [ ] Credit display and warnings - [ ] Image upload ### Integration - [ ] End-to-end generation flow - [ ] Credit deduction → generation → completion - [ ] Webhook vs polling updates ## Next Steps (Phase 4) 1. Payment integration with Stripe 2. Retry logic for failed generations 3. Cancel in-progress generations 4. In-app video player 5. Batch operations 6. Admin panel ## Environment Variables ### New Required Variables - REPLICATE_WEBHOOK_SECRET - For webhook signature verification See PHASE_3_IMPLEMENTATION.md for complete setup instructions. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
