Implemented VWB authentication support for Verily Workbench service accounts with isVwbServiceAccount and domain bypass, accompanied by tests and safety enhancements. Enabled VWB egress alerts and notifications with Jira and email integrations and refactored the alerting flow to handle VWB-specific notifications. Improved egress data modeling by adding time_window_start and splitting EgressEventMapper into SumologicEgressEventMapper and VwbEgressEventMapper, enabling source-specific analytics. Cleaned Leonardo app usage reporting by removing the customEnvironmentVariables field, aligning queries and extraction with data collection requirements. Modernized API specifications and security: switched YAML to camelCase, removed bearerAuth, and adjusted API paths for cleaner security posture. Made Sumologic integration optional by allowing a null field, addressing edge-case handling. Refactored Workspace Service Manager into a dedicated package, and added Verily Workbench API clients and OpenAPI specs for User Manager and Exfil Manager with build integration. These changes collectively improve security posture, system maintainability, cross-team collaboration, and time-to-value for VWB and AoU integrations.
