Proof step 15 from proof inv-write-echdr (previous step)

# buf1 = EB_PAGE_SIZE, pebs[m0] = mkpeb(buf0, 0, false), err = ESUCCESS, aehdr.valid?, m0 < # pebs, mtd-cons(pebs), err = ESUCCESS → is-encoded(echdr(aehdr.ec), buf1), err = ESUCCESS ∨ ⌊err⌋ ⊦ ⟪mtd_asm_write#(m0, 0, 0, EB_PAGE_SIZE, buf1; pebs; err)⟫ mtd-cons(pebs)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 16:
# buf1 = EB_PAGE_SIZE, pebs[m0] = mkpeb(buf0, 0, false), aehdr.valid?, m0 < # pebs, is-encoded(echdr(aehdr.ec), buf1), mtd-cons(pebs) ⊦ ⟪mtd_asm_write#(m0, 0, 0, EB_PAGE_SIZE, buf1; pebs; err)⟫ mtd-cons(pebs)
