AWS AmazonCloudWatch documentation change
Summary
Added 'muteDetail' fields to various alarm event examples showing mute rule implementation details including ARN and time windows.
Security assessment
Documents new mute rule capabilities in event structures, which helps manage alert fatigue during maintenance. No vulnerability is addressed, but it enhances documentation of security-adjacent operational controls.
