@claude - Let's update the Mattermost Product Documentation to note new debug log messages for cluster job execution from Mattermost server v11.4.0 onward captured via Engineering PR #34701 (evidence: milestone.title from PR metadata).

Scope & constraints:

• In scope: Add debug log message references to existing cluster/logging documentation
• Out of scope (non-editable): Changelogs, important upgrade notes, version archive
• Bounded to: Three job types (scheduled posts, DND status reset, post reminders) and their debug messages

Required doc touchpoints:

Identify existing documentation for:

• Server logging reference (if log messages are documented)
• High availability / cluster troubleshooting guides
• Scheduled jobs / task execution documentation

Task (System Admin):

Document the new debug log messages that explain cluster leader job execution:

New debug messages added in v11.4.0:

• "Skipping scheduled posts job startup since this is not the leader node"
• "Skipping unset DND status job startup since this is not the leader node"
• "Skipping post reminder job startup since this is not the leader node"
• "This is no longer leader node. Cancelling the [job name] task"

Context to include:

• These are DEBUG-level messages (only visible when debug logging enabled)
• Appear in cluster deployments when non-leader nodes skip job execution
• Normal/expected behavior - indicates leader election working correctly
• Helpful for troubleshooting: if admin wonders why jobs aren't running on a specific node, these messages confirm it's not the leader

Output requirements:

• List of documentation pages updated
• Before/after showing where debug messages are referenced
• Confirmation that cluster troubleshooting context is included (these messages indicate correct behavior, not errors)

Evidence used:

• PR metadata: milestone.title = "v11.4.0"
• Code diff: 5 debug statements added across three job initialization functions
• Release note: "Added debug log to indicate the scheduled post job, DND status reset job, or the post reminder job is not running as the current node not being a leader node"
• Jobs affected: scheduled posts, DND status expiry, post reminders
