February 2025: Delivered foundational protection for sensitive properties and improved save UX for match forms and bulk changes in libris/lxlviewer. The Protected Properties Locking and Protection Framework introduces lock/unlock controls, unlock confirmation, visual indicators, and path-based, centralized configuration to reduce accidental edits and simplify policy enforcement. The Match Form and Bulk Changes UX and Saving Enhancements improve save performance when differences exist, clarify steps, and ensure correct form handling during spec saves, resulting in faster, more reliable edits with clearer user guidance. Fixed critical save-flow bugs and refined event handling to reflect the active form, reducing risk of incorrect state transitions.
