+- ✅ DST-safe time calculations
+- ✅ Multi-level duplicate prevention
+- ✅ Time/timezone change detection and recovery
+- ✅ Race condition prevention
+- ✅ Comprehensive edge case handling
+
+### Architecture Components
+1. **TimeChangeDetector** — Detects time changes
+2. **TimezoneChangeDetector** — Detects timezone changes  
+3. **RolloverCoordinator** — Coordinates rollover operations

+## Detailed File Modifications
+
+### 1. DailyNotificationScheduler.swift
+
+**Location**: `ios/Plugin/DailyNotificationScheduler.swift`
+
+#### Change 1.1: Add DST-Safe Next Time Calculation
+
+**Insert after line 307** (after `calculateNextOccurrence` method):
+
+```swift
+/**
+ * Calculate next scheduled time from current scheduled time (24 hours later, DST-safe)
+ * 
+ * Matches Android calculateNextScheduledTime() functionality
+ * Handles DST transitions automatically using Calendar
+ * 
+ * @param currentScheduledTime Current scheduled time in milliseconds
+ * @return Next scheduled time in milliseconds (24 hours later)
+ */
+func calculateNextScheduledTime(_ currentScheduledTime: Int64) -> Int64 {
+    let calendar = Calendar.current
+    let currentDate = Date(timeIntervalSince1970: Double(currentScheduledTime) / 1000.0)
+    
+    // Add 24 hours (handles DST transitions automatically)
+    guard let nextDate = calendar.date(byAdding: .hour, value: 24, to: currentDate) else {
+        // Fallback to simple 24-hour addition if calendar calculation fails
+        print("\(Self.TAG): DST calculation failed, using fallback")
+        return currentScheduledTime + (24 * 60 * 60 * 1000)
+    }
+    
+    // Validate: Log DST transitions for debugging
+    let currentHour = calendar.component(.hour, from: currentDate)
+    let currentMinute = calendar.component(.minute, from: currentDate)

+    }
+    
+    return Int64(nextDate.timeIntervalSince1970 * 1000)
+}
+```
+
+#### Change 1.2: Add Rollover Scheduling Method
+
+**Insert after line 202** (after `scheduleNotification` method):
+
+```swift
+/**
+ * Schedule next notification after current one fires (rollover)
+ * 
+ * Matches Android scheduleNextNotification() functionality
+ * Implements multi-level duplicate prevention
+ * 
+ * @param content Current notification content that just fired
+ * @param storage Storage instance for duplicate checking
+ * @param fetcher Optional fetcher for scheduling prefetch
+ * @return true if next notification was scheduled successfully

+    }
+}
+```
+
+**Note**: The `formatTime` method already exists (line 273), so no change needed there.
+
+---
+
+### 2. DailyNotificationPlugin.swift
+
+**Location**: `ios/Plugin/DailyNotificationPlugin.swift`
+
+#### Change 2.1: Add Rollover Handler Method + Notification Observer
+
+**Insert after line 77** (in `load()` method, after recovery manager initialization):
+
+```swift
+// Register for notification delivery events (Notification Center pattern)
+NotificationCenter.default.addObserver(
+    self,
+    selector: #selector(handleNotificationDelivery(_:)),
+    name: NSNotification.Name("DailyNotificationDelivered"),
+    object: nil
+)
+```
+
+**Insert after line 1242** (after `getNotificationStatus` method):
+
+```swift
+/**
+ * Handle notification delivery event (from Notification Center)
+ * 
+ * This is called when AppDelegate posts notification delivery event
+ * Matches Android's scheduleNextNotification() behavior
+ * 
+ * @param notification NSNotification with userInfo containing notification_id and scheduled_time
+ */
+@objc private func handleNotificationDelivery(_ notification: Notification) {
+    guard let userInfo = notification.userInfo,
+          let notificationId = userInfo["notification_id"] as? String,
+          let scheduledTime = userInfo["scheduled_time"] as? Int64 else {
+        print("DNP-ROLLOVER: Invalid notification data")
+        return
+    }
+    
+    Task {
+        await processRollover(notificationId: notificationId, scheduledTime: scheduledTime)
+    }
+}
+
+/**
+ * Process rollover for delivered notification
+ * 
+ * @param notificationId ID of notification that was delivered
+ * @param scheduledTime Scheduled time of delivered notification
+ */
+private func processRollover(notificationId: String, scheduledTime: Int64) async {
+    guard let scheduler = scheduler, let storage = storage else {
+        print("DNP-ROLLOVER: Plugin not initialized")
+        return
+    }
+    
+    // Get the notification content that was delivered
+    guard let content = storage.getNotificationContent(id: notificationId) else {
+        print("DNP-ROLLOVER: Could not find notification content for id=\(notificationId)")
+        return
+    }
+    
+    // Schedule next notification
+    // Note: DailyNotificationFetcher integration deferred to Phase 2
+    let scheduled = await scheduler.scheduleNextNotification(
+        content,
+        storage: storage,
+        fetcher: nil // TODO: Phase 2 - Add fetcher instance
+    )
+    
+    if scheduled {
+        print("DNP-ROLLOVER: Successfully scheduled next notification for id=\(notificationId)")
+        // Log success (non-fatal, background operation)
+    } else {
+        print("DNP-ROLLOVER: Failed to schedule next notification for id=\(notificationId)")
+        // Log failure but continue (recovery will handle on next launch)
+    }
+}
+```
+
+#### Change 2.2: Update getNotificationStatus to Include Rollover Info
+
+**Modify line 1229-1236** (in `getNotificationStatus` method):
+
+```swift
+// Calculate next notification time
+let nextNotificationTime = await scheduler.getNextNotificationTime() ?? 0
+
+// Get rollover status
+let lastRolloverTime = await storage?.getLastRolloverTime() ?? 0
+
+var result: [String: Any] = [
+    "isEnabled": isEnabled,
+    "isScheduled": pendingCount > 0,
+    "lastNotificationTime": lastNotification?.scheduledTime ?? 0,
+    "nextNotificationTime": nextNotificationTime,
+    "pending": pendingCount,
+    "rolloverEnabled": true, // Indicate rollover is active
+    "lastRolloverTime": lastRolloverTime, // When last rollover occurred
+    "settings": settings
+]
+```
+
+---
+
+### 3. AppDelegate.swift
+
+**Location**: `test-apps/ios-test-app/ios/App/App/AppDelegate.swift`
+
+#### Change 3.1: Modify willPresent to Trigger Rollover
+
+**Replace lines 136-152** with:
+
+```swift
+func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
+    NSLog("DNP-DEBUG: ✅ userNotificationCenter willPresent called!")
+    NSLog("DNP-DEBUG: Notification received in foreground: %@", notification.request.identifier)
+    NSLog("DNP-DEBUG: Notification title: %@", notification.request.content.title)
+    NSLog("DNP-DEBUG: Notification body: %@", notification.request.content.body)
+    
+    // Extract notification info from userInfo for rollover
+    let userInfo = notification.request.content.userInfo
+    if let notificationId = userInfo["notification_id"] as? String,
+       let scheduledTime = userInfo["scheduled_time"] as? Int64 {
+        
+        // Trigger rollover scheduling (async, non-blocking)
+        Task {
+            await handleNotificationRollover(notificationId: notificationId, scheduledTime: scheduledTime)
+        }
+    }
+    
+    // Show notification with banner, sound, and badge
+    // Use .banner for iOS 14+, fallback to .alert for iOS 13
+    if #available(iOS 14.0, *) {
+        completionHandler([.banner, .sound, .badge])
+    } else {
+        completionHandler([.alert, .sound, .badge])
+    }
+    
+    NSLog("DNP-DEBUG: ✅ Completion handler called with presentation options")
+}
+```
+
+#### Change 3.2: Post Notification for Rollover (Notification Center Pattern)
+
+**Insert after line 152** (after `willPresent` completion handler):
+
+```swift
+// Post notification to trigger rollover (decoupled pattern)
+NotificationCenter.default.post(
+    name: NSNotification.Name("DailyNotificationDelivered"),
+    object: nil,
+    userInfo: [
+        "notification_id": notificationId,
+        "scheduled_time": scheduledTime
+    ]
+)
+```
+
+**Note**: This uses Notification Center pattern for decoupling. Plugin will observe this notification.
+
+---
+
+### 4. DailyNotificationStorage.swift
+
+**Location**: `ios/Plugin/DailyNotificationStorage.swift`
+
+#### Change 4.1: Add Rollover State Tracking Methods
+
+**Insert after line 148** (after `getAllNotifications` method):
+
+```swift
+/**
+ * Get last rollover time for a notification ID
+ * 
+ * @param notificationId Notification ID
+ * @return Last rollover time in milliseconds, or nil if never rolled over
+ */
+func getLastRolloverTime(for notificationId: String) async -> Int64? {
+    let key = "rollover_\(notificationId)"
+    let lastTime = userDefaults.object(forKey: key) as? Int64
+    return lastTime
+}
+
+/**
+ * Save last rollover time for a notification ID
+ * 
+ * @param notificationId Notification ID
+ * @param time Rollover time in milliseconds
+ */
+func saveLastRolloverTime(for notificationId: String, time: Int64) async {
+    let key = "rollover_\(notificationId)"
+    userDefaults.set(time, forKey: key)
+    userDefaults.synchronize()
+}
+
+/**
+ * Get last rollover time (any notification)
+ * 
+ * @return Last rollover time in milliseconds, or 0 if never rolled over
+ */
+func getLastRolloverTime() -> Int64 {
+    let key = "rollover_last"
+    return Int64(userDefaults.integer(forKey: key))
+}
+
+/**
+ * Save last rollover time (any notification)
+ * 
+ * @param time Rollover time in milliseconds
+ */
+func saveLastRolloverTime(_ time: Int64) {
+    let key = "rollover_last"
+    userDefaults.set(time, forKey: key)
+    userDefaults.synchronize()
+}
+```
+
+---
+
+### 5. DailyNotificationReactivationManager.swift
+
+**Location**: `ios/Plugin/DailyNotificationReactivationManager.swift`
+
+#### Change 5.1: Add Rollover Check to Recovery
+
+**Insert after line 338** (in `performColdStartRecovery` method, after detecting missed notifications):
+
+```swift
+// Step 4.5: Check for delivered notifications and trigger rollover
+// This handles notifications that were delivered while app was not running
+await checkAndProcessDeliveredNotifications()
+```
+
+#### Change 5.2: Add Delivered Notifications Check Method
+
+**Insert at end of class** (before closing brace):
+
+```swift
+/**
+ * Check for delivered notifications and trigger rollover
+ * 
+ * This ensures rollover happens on app launch if notifications were delivered
+ * while the app was not running
+ */
+private func checkAndProcessDeliveredNotifications() async {
+    print("\(Self.TAG): Checking for delivered notifications to trigger rollover")
+    
+    // Get delivered notifications from system
+    let deliveredNotifications = await notificationCenter.deliveredNotifications()
+    
+    // Get last processed rollover time from storage
+    let lastProcessedTime = storage.getLastRolloverTime()

+        
+        guard let notificationId = userInfo["notification_id"] as? String,
+              let scheduledTime = userInfo["scheduled_time"] as? Int64 else {
+            continue
+        }
+        
+        // Only process if this notification hasn't been processed yet

+                continue
+            }
+            
+            // Trigger rollover
+            let scheduled = await scheduler.scheduleNextNotification(

+                storage: storage,
+                fetcher: nil // TODO: Add fetcher in Phase 2
+            )

+
+## Integration Points
+
+### 1. AppDelegate → Plugin (Notification Center Pattern)
+- **Flow**: AppDelegate detects notification → posts Notification Center event → plugin observes and handles
+- **Challenge**: Decoupling AppDelegate from plugin
+- **Solution**: Use Notification Center for decoupled communication
+
+### 2. Plugin → Scheduler
+- **Flow**: Plugin receives rollover request → calls scheduler method
+- **Challenge**: Passing storage and fetcher instances
+- **Solution**: Plugin maintains references, passes to scheduler
+
+### 3. Scheduler → Storage
+- **Flow**: Scheduler checks duplicates → queries storage
+- **Challenge**: Thread safety
+- **Solution**: Storage methods are already thread-safe (UserDefaults)
+
+### 4. Recovery Manager → Scheduler
+- **Flow**: Recovery detects delivered notifications → triggers rollover
+- **Challenge**: Ensuring rollover happens on app launch
+- **Solution**: Integrate into existing recovery flow
+
+---
+
+## Dependencies & Order
+
+### Implementation Order
+
+1. **Phase 1: Core Infrastructure**
+   - ✅ Add `calculateNextScheduledTime` to Scheduler
+   - ✅ Add `scheduleNextNotification` to Scheduler
+   - ✅ Add rollover state tracking to Storage
+   - ✅ Add `handleNotificationRollover` to Plugin
+
+2. **Phase 2: Detection Mechanisms**
+   - ✅ Modify AppDelegate `willPresent` method
+   - ✅ Add rollover check to Recovery Manager
+   - ✅ Test foreground delivery
+
+3. **Phase 3: Edge Case Handling** (Future)
+   - Add TimeChangeDetector
+   - Add TimezoneChangeDetector
+   - Add RolloverCoordinator
+
+4. **Phase 4: Integration** (Future)
+   - Integrate fetcher for prefetch scheduling
+   - Add comprehensive logging
+   - Performance optimization
+
+---
+
+## Testing Strategy
+
+### Test 1: Foreground Delivery
+- **Setup**: App running, notification fires
+- **Expected**: Rollover triggers via AppDelegate → Notification Center → Plugin
+- **Verify**: Next notification scheduled, logs show rollover success
+
+### Test 2: Background Delivery
+- **Setup**: App not running, notification fires
+- **Expected**: Rollover triggers on app launch via Recovery Manager
+- **Verify**: Next notification scheduled, recovery logs show rollover
+
+### Test 3: Duplicate Prevention
+- **Setup**: Trigger rollover multiple times (rapid fire)
+- **Expected**: Only one notification scheduled
+- **Verify**: No duplicates in system, logs show duplicate prevention
+
+### Test 4: DST Transition
+- **Setup**: Schedule notification on DST transition day
+- **Expected**: 24-hour calculation handles DST correctly
+- **Verify**: Notification fires at correct time, logs show DST transition
+
+### Test 5: Error Handling
+- **Setup**: Simulate failure (e.g., invalid notification ID)
+- **Expected**: Error logged, app continues, no crash
+- **Verify**: Logs show error, recovery handles on next launch

+## Open Questions — RESOLVED
+
+**See**: `docs/ios-rollover-open-questions-answers.md` for detailed answers
+
+### Summary of Decisions:
+
+1. **Fetcher Integration**: ✅ Defer to Phase 2, use optional parameter pattern
+2. **AppDelegate Access**: ✅ Use Notification Center pattern (decoupling, flexibility)
+3. **Background Task**: ✅ Rely on existing recovery + AppDelegate (no dedicated task)
+4. **Error Handling**: ✅ Log + Continue (non-fatal), no retry, no user notification
+5. **Performance**: ✅ Process individually (low volume, simplicity)
+6. **Testing**: ✅ Manual testing for Phase 1, automated tests for Phase 2
+
