 ## v20260115-01-autotask-settings
 
-Changes:
+### Changes:
 - Added initial Autotask integration settings structure to Backupchecks.
 - Introduced new system settings demonstrating Autotask configuration fields such as enable toggle, environment selection, credentials, tracking identifier, and Backupchecks base URL.
 - Prepared data model and persistence layer to store Autotask-related configuration.
 - Laid groundwork for future validation and integration logic without enabling ticket creation or customer mapping.
 - Ensured changes are limited to configuration foundations only, keeping Phase 1 scope intact.

 - Added safe, idempotent column existence checks to prevent startup failures on re-deployments.
 - Ensured all Autotask-related system_settings columns are created before being queried.
 - Prevented aborted database transactions caused by missing columns during settings initialization.
 - Improved overall stability of the Settings page when Autotask integration is enabled.
