Decision 01
One step, never a list
The model must return exactly one action. A validator reads each answer and rejects compound steps, numbered sub-steps and timers. An earlier version hid the rest of the path, and that caused its own freeze. So now the whole path shows, with one step lit and the rest marked as held for later.
A list can’t reach the screen. If the model can’t produce one small step, the turn fails visibly.
