I suppose I’m still confused on what the problem is here.
You can only move into a static stance at the start of your turn, you can then move to a dynamic stance as a free action. After you have taken an action it is no longer the start of your turn, so once you have performed any action you can no longer go back into a dynamic stance. As per the rules of movement you can only enter a dynamic stance with the intent to cover ground, so at no point can you enter a dynamic stance unless you have at least half an action left with which to move.
So the possible scenarios are:
Static stance > Full Attack
Static Stance >Shift to dynamic > Full Move
Static Stance > Shift to dynamic > Half Move > Half Attack
That’s it. You can’t make a full attack and then use a free action to switch to a dynamic because you can no longer cover any ground, you used all your actions. You also cannot move then shift back to a static stance before the attack because it is no longer the start of your turn.
