The Xfinity Cybersecure alert on your iPhone was provoked by ad-exchange or domain-reputation tracking during your thesaurus.com lookup. The simultaneous black background switch in macOS Notes was caused by sunset Auto-Appearance mode or an iCloud CloudKit push syncing appearance preferences from your iPhone. No keystroke logging, malware payload, or unauthorized remote session exists.

Competing Explanatory Models Toggle focus
Model A: Benign Double Coincidence
