October 2025 — abcxyz/team-link: Delivered safety and reliability enhancements to the SCIM workflow. Implemented a configurable pre-deactivation sanity check in EnterpriseUserWriter to prevent accidental user removals, integrated it into the deactivation flow, improving data integrity. Hardened group synchronization by aborting on errors from the group reader or user mapper, clarifying error messages, and expanding tests to increase reliability and observability. These changes reduce risk of unintended deletions and synchronization failures, contributing to smoother identity management and faster issue resolution.
