```

## From README

Unity In-App Purchasing Namespace: UnityEngine.Purchasing | Security: UnityEngine.Purchasing.Security Package: com.unity.purchasing Unity IAP has its own initialization path via UnityIAPServices.StoreController() → store.Connect(). It does not require UnityServices.InitializeAsync(), but they can coexist if your project uses other UGS services. If Analytics is present and InitializeAsync() is called, IAP will automatically send transaction events. Before You Start Always read references/pre-check.md first. It scans the project for third-party IAP packages, native Google Billing, and existing Unity IAP versions, then routes to the correct path. Do not read any other reference file or make any changes until routing is resolved.
