Status: IN
Temporal regression is prevented by two independent structural mechanisms operating at different architectural levels: one-directional state machines enforce irrevocable transitions (OPEN→CLOSED→FINALIZED) that contain temporal gaps at the control-flow level, while unconditional state monotonicity ensures the underlying data lattice only grows — making backward state motion impossible at both control-flow and data-flow levels.
control-plane state machines + data-plane monotonic growth independently prevent regression at their respective levels
