Six genuine native 75 ms XSPICE trajectories from TWO exactly matched initial phase triples. For each seed the only controller changes are fast-ripple EMA headroom or consecutive over-limit windows. No phase-map knowledge is given to the native controller.
White dashed contour: only a 3mV static fixed-phase reference from the independently sampled native landscape. It is NOT a safe boundary for the controller. The true guard is a private time-dependent 10µs switching-ripple RMS EMA. Red × markers annotate actual stage4 guard aborts from accepted XSPICE state, if any.
