Keep command-local history, purge and rollback intact, then consolidate affected documents at action completion or dialog suspension. Preserve semantic no-op identity and redo, visibility semantics and row identifiers. Bind dialog continuation to its exact document/history, inherit the setting in scratch sessions and carry droplet action names. Add the review counterexamples and focused continuation, Batch/droplet and history-option controls. Source is formatted; compilation and runtime qualification remain pending.
