Proof step 55 from proof test (previous step)

Heuristic symbolic execution applied rule assign right

And obtained the following new goals

Proof step 54:
buf = mk(mkarray(2)[0, a], 2, 0, 1), j0 = (buf .first + buf .len) % buf .size, buf1 = buf ⊦ ⟪put#(j0, b; buf1 .data)⟫ ⟪buf1 := buf1 .len:= (buf1 .len + 1)⟫ ⟪pop#(; buf1, a0) ; assert#(a0 = a) ; push#(c; buf1) ; pop#(; buf1, a0) ; assert#(a0 = b) ; pop#(; buf1, a0) ; assert#(a0 = c)⟫ true
