## ADDED Requirements

### Requirement: Guide the user through Xiaomi background setup
The app SHALL provide explicit guidance and shortcuts for the Xiaomi/HyperOS settings required for reliable background behavior.

#### Scenario: User opens background setup
- **WHEN** the user opens the app's background setup section
- **THEN** the app MUST show checklist items for SMS permission, autostart, battery unrestricted mode, notification visibility, and keepalive service state

#### Scenario: Xiaomi autostart settings shortcut is available
- **WHEN** the app can resolve a Xiaomi/HyperOS autostart settings activity
- **THEN** it MUST open that settings page from the setup UI

#### Scenario: Xiaomi autostart shortcut is unavailable
- **WHEN** the explicit Xiaomi settings activity cannot be resolved or launched
- **THEN** the app MUST fall back to application details or general settings
- **AND** it MUST keep the manual setup checklist visible

### Requirement: Represent manual-only settings honestly
The app SHALL distinguish settings that can be detected through Android APIs from settings that require manual user confirmation.

#### Scenario: Battery optimization state is queried
- **WHEN** the app checks Android battery optimization status
- **THEN** it MUST use `PowerManager.isIgnoringBatteryOptimizations` where available
- **AND** display whether Android reports the app as ignoring battery optimizations

#### Scenario: Xiaomi autostart state cannot be read
- **WHEN** no stable public API exists to read the Xiaomi autostart switch
- **THEN** the app MUST ask the user to manually confirm completion instead of pretending to detect it

#### Scenario: Battery unrestricted state cannot be read
- **WHEN** no stable public API exists to read the HyperOS per-app battery unrestricted option
- **THEN** the app MUST ask the user to manually confirm completion

### Requirement: Provide battery optimization actions
The app SHALL provide Android-standard actions for battery optimization setup.

#### Scenario: User opens battery optimization settings
- **WHEN** the user taps the battery optimization settings action
- **THEN** the app MUST launch `Settings.ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS` when available

#### Scenario: User requests direct exemption
- **WHEN** the app offers a direct ignore-battery-optimization request
- **THEN** it MUST use `Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS`
- **AND** explain that exemption still does not guarantee unlimited background execution

### Requirement: Preserve user control
The app SHALL keep background keepalive opt-in and reversible.

#### Scenario: First app launch after install
- **WHEN** the app is launched for the first time
- **THEN** background keepalive MUST be disabled until the user enables it

#### Scenario: User turns off keepalive
- **WHEN** the user turns off keepalive
- **THEN** boot restore MUST no longer restart the keepalive service
