again your trying to show the A<>B commitment

the ascii art of the bolts 2. is that -(1)->   -(2)-> -(3)-> is the LN millisat promise part simplified.
using the diagram in my last post 123 is equivelent to 1,2,9 of the 3 millisat payment promise updates that in the colourful image between alice and bob..
the commitment your ascii art 4 doesnt happen until after your ascii art 3(my diagram9)
