[jsingh6]

Test Case PR1-B005-TC08 — Corrupted UserDefaults priority data is handled gracefully on app launch

Field	Value
Priority	P1
Behavior	PR1-B005
Type	error_state
PR of origin	#1

Preconditions

• App is installed
• At least one todo exists with a valid priority saved in UserDefaults

Steps

1. Using a device file manager or debug tool, manually corrupt the priority field in the UserDefaults plist for an existing todo (e.g., set it to an unexpected string or invalid type)
2. Launch the app
3. Navigate to the todo list
4. Observe the affected todo item

Expected Result

The app does not crash. The affected todo is either shown with a safe fallback/default priority or displays an appropriate error state. Other todos with valid data are unaffected.
