Proof step 7 from proof inv-write-echdr (previous step)

pebs[m0] = mkpeb(buf, 0, false), m = EB_PAGE_SIZE, aehdr.valid?, m0 < # pebs, mtd-cons(pebs) ⊦ ⟪let buf = mkbuf(m), ehdr = echdr(aehdr.ec) in {encode_echeader#(m, ehdr; buf; err); if err = ESUCCESS then mtd_asm_write#(m0, 0, 0, m, buf; pebs; err)}⟫ mtd-cons(pebs)

Heuristic symbolic execution applied rule let right

And obtained the following new goals

Proof step 8:
pebs[m0] = mkpeb(buf0, 0, false), buf = mkbuf(m), ehdr = echdr(aehdr.ec), m = EB_PAGE_SIZE, aehdr.valid?, m0 < # pebs, mtd-cons(pebs) ⊦ ⟪encode_echeader#(m, ehdr; buf; err); if err = ESUCCESS then mtd_asm_write#(m0, 0, 0, m, buf; pebs; err)⟫ mtd-cons(pebs)
Proof step 19:
pebs[m0] = mkpeb(buf, 0, false), m = EB_PAGE_SIZE, aehdr.valid?, m0 < # pebs, mtd-cons(pebs) ⊦ aehdr.valid?
