Proof step 14 from proof ls-datasize-wear-level (previous step)

# buf = LEB_SIZE, LEB_SIZE = n1 + m, buf = subarray(buf, 0, m) + subarray(buf, m, n1), subarray(buf, m, n1) = mkempbuf(n1), m < datasize(buf, LEB_SIZE), is-aligned(m, EB_PAGE_SIZE), m ≤ LEB_SIZE ⊦

User applied rule insert equation

And obtained the following new goals

Proof step 15:
#(subarray(buf, 0, m) + subarray(buf, m, n1)) = LEB_SIZE, LEB_SIZE = n1 + m, subarray(subarray(buf, 0, m) + subarray(buf, m, n1), m, n1) = mkempbuf(n1), m < datasize(subarray(buf, 0, m) + subarray(buf, m, n1), LEB_SIZE), is-aligned(m, EB_PAGE_SIZE), m ≤ LEB_SIZE ⊦
