Description: When a user's iCloud storage is full, the Notes app continues to save recent edits locally to a pending-sync cache. However, if the user toggles iCloud Notes sync to "Off" in System Settings, macOS executes a total database purge script.
The system completely ignores error flags indicating that the local edits never successfully reached the cloud server. This creates a critical edge case resulting in permanent user data loss.
Requested Change: Implement an explicit safeguard check prior to executing the local cache purge. If local_edits > cloud_edits, the system must present a warning modal stating: "Your most recent edits have not yet uploaded to iCloud due to full storage. Disabling sync will permanently delete these un-saved notes from this device."
