Proof step 129 from proof prepost-read-log (previous step)

# buf = EB_PAGE_SIZE, LEB_SIZE = n1 + logoff0, avol[m5] = mapped(buf1), logoff0 < LEB_SIZE, m5 < # avol, ebm-vol-inv(avol), is-aligned(logoff0, EB_PAGE_SIZE), is-encoded(log, subarray(buf1, 0, logoff0)), is-encoded(log0, buf1), logoff0 ≤ # buf1, logoff0 + EB_PAGE_SIZE ≤ LEB_SIZE ⊦ n1 = 0, ∃ err0. ⌊err0⌋ ∨ err0 = ESUCCESS

And closed the goal!

Additional information

Used simplifier rules: ⊦ ESUCCESS ≠ ECOMMIT; (s)% ⊦ m ≠ n → (m ≤ n ↔ m < n); (s)% ⊦ ⌊ECOMMIT⌋ ; (s)%# buf = n ⊦ subarray(buf, 0, n) = buf; (s)% ⊦ is-encoded(nx0, buf) → (is-encoded(nx1, buf) ↔ nx0 = nx1); (s) Used terms: ECOMMIT
