When Chrome encounters an extension entry in Secure Preferences with a bad HMAC, it doesn't crash or warn loudly — it moves the entry to prefs.tracked_preferences_reset and continues without the extension. This is a defensive self-heal mechanism that makes silent tampering invisible: your config 'looks' injected, the directory has files, but Chrome is quietly undoing your work every restart. Diagnose by checking tracked_preferences_reset for orphaned entries.
