{"role": "assistant", "content": "I'll implement this feature in phases:\n\n**Phase 1: Backend - Apple Receipt Validation**\n1. Create `v1/payments/` module with Apple IAP endpoints\n2. Implement receipt validation with Apple's servers\n3. Integrate with existing PointsService for crediting\n4. Add purchase tracking\n\n**Phase 2: iOS - StoreKit2 Integration**\n1. Create `features/payments/` module in Flutter\n2. Implement StoreKit2 product fetching\n3. Implement purchase flow\n4. Connect to backend validation endpoint\n\n**Phase 3: Error Handling & Testing**\n1. Add error codes to http-error-codes.md\n2. Handle edge cases (network, cancelled, pending)\n3. Add integration tests\n\nLet me start with Phase 1."}
