Changes

Finding	Type	Module	Doc	Action
f001	config_drift	on-call/integration	zh/en/on-call/integration/alert-integration/alert-sources/db-pull.mdx	Updated DB Pull cycle default/minimum and initial time required/default behavior
f002	feature_drift	on-call	zh/en/on-call/analytics/insights.mdx	Updated CSV export field selection, labels/custom fields support, HTML-to-text option, and export limits

• Check Insights CSV export descriptions against the current export popover
• Ensure zh/en wording remains aligned

Validation
