Heuristic symbolic execution applied rule if positive right

And obtained the following new goals

Proof step 7:
pebs[m3] = mkpeb(buf1, m1, false), buf0 = buf, m = m2, m0 = m3, m3 < # pebs, mtd-cons(pebs), n0 + n ≤ # buf, m2 + n ≤ PEB_SIZE ⊦ ⟪fail_or_success#(; ; err); bitflips := ?; if err = ESUCCESS then buf0 := copy(pebs[m0].data, m, buf0, n0, n) else choose buf with # buf = # buf0 ∧ range=(buf, 0, buf0, 0, n0) ∧ range=(buf, n0 + n, buf0, n0 + n, # buf0 - n0 + n) in buf0 := buf⟫ true
