- Improved get_service_name filter plugin (clearer suffix handling, consistent var names). - Added MODE_ASSERT flag to optionally execute validation/assertion tasks. - Fixed systemd unit handling: consistent use of %I instead of %i, correct escaping of instance names. - Unified on_failure behavior and alarm composer scripts. - Cleaned up redundant logging, handlers, and debug config. - Strengthened sys-service template resolution with assert (only active when MODE_ASSERT). - Simplified timer and suffix handling with get_service_name filter. - Hardened sensitive tasks with no_log. - Added conditional asserts across roles (Keycloak, DNS, Mailu, Discourse, etc.). These changes improve consistency, safety, and validation across the automation stack. Conversation: https://chatgpt.com/share/68a4ae28-483c-800f-b2f7-f64c7124c274
