# Cloud User Account Change Handling

## Goal

React when the cloud user account status changes (signed in/out, restricted, etc.).

## Actions Required

| Action                    | Purpose                                             |
| ------------------------- | --------------------------------------------------- |
| CloudServicesOnUserChange | Listen for cloud user status changes (persistent)   |
| CloudServicesGetUserInfo  | Read cached user id/status after availability event |
| CloudServicesSynchronize  | Sync after user becomes available (optional)        |

## Variables Needed

* (optional) lastKnownState (String/Enum in your FSM)

## Implementation Steps

### 1. State: RegisterUserListener (Persistent)

**Action:** CloudServicesOnUserChange

* **Events:**
  * availableEvent → CloudAvailable
  * noAccountEvent → CloudUnavailable
  * restrictedEvent → CloudUnavailable
  * couldNotDetermineEvent → CloudUnavailable

### 2. State: CloudAvailable

Call `CloudServicesGetUserInfo` to read `userId` and `accountStatus`, enable cloud save UI, and optionally call `CloudServicesSynchronize` to refresh snapshot/values.

### 3. State: CloudUnavailable

Disable cloud save UI and fall back to local-only storage.

## Notes

* On iOS this commonly maps to iCloud account availability.
* Keep this listener active if your app needs to respond during runtime.
