Concurrency Control in Groupware Systems

Summary: Proposes a simple, lock-free concurrency control algorithm for real-time groupware, enabling direct edits without locking and supporting fine-grained sharing. The framework uses operation semantics yet remains largely semantics-agnostic, enabling broad applicability (e.g., group-text editing) with a correctness sketch; non-serializable behavior is supported.
