When an operator mutated IFC then raised mid-execute the user was left staring at a raw traceback with the IFC graph captured by the active transaction but the Blender side stale. Blender does not push an undo step for a raised operator (the same gap that the CANCELLED-modal arm patches via bpy.ops.ed.undo_push), so the WARNING the framework can emit is only honest if it pushes that undo step too. The framework now detects partial state via ifc_file.transaction.operations, pushes a Recover undo step, then reports a WARNING naming Ctrl+Z so the recovery path is discoverable. The bespoke try/except wrapper in UnjoinWallPathConnection becomes redundant and is retired in the same change. Generated with the assistance of an AI coding tool.
