+# validate-ios-logs.sh - Validates prefetch log sequence for iOS DailyNotificationPlugin
+#
+# Purpose: Automatically validates that all critical log steps occurred in proper order
+#          for a complete prefetch cycle (registration → scheduling → execution → delivery)
+#
+# Usage:
+#   # From log file
+#   ./scripts/validate-ios-logs.sh device.log
+#
+#   # From stdin (grep filtered)
+#   grep -E "\[DNP-(FETCH|SCHEDULER|PLUGIN)\]" device.log | ./scripts/validate-ios-logs.sh
+#
+#   # From Xcode console output
+#   xcrun simctl spawn booted log stream --predicate 'subsystem == "com.timesafari.dailynotification"' | ./scripts/validate-ios-logs.sh
+#
+# Author: Matthew Raymer
+# Date: 2025-11-15
