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

pebs[m0] = mkpeb(buf, EB_PAGE_SIZE, false), m = EB_PAGE_SIZE, avhdr.valid?, m0 < # pebs, mtd-cons(pebs) ⊦ ⟪let buf = mkbuf(m), vhdr = vidhdr(avhdr.vol, avhdr.leb, avhdr.sqn, avhdr.size, avhdr.checksum) in {encode_vidheader#(m, vhdr; buf; err); if err = ESUCCESS then mtd_asm_write#(m0, m, 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, EB_PAGE_SIZE, false), buf = mkbuf(m), m = EB_PAGE_SIZE, vhdr = vidhdr(avhdr.vol, avhdr.leb, avhdr.sqn, avhdr.size, avhdr.checksum), avhdr.valid?, m0 < # pebs, mtd-cons(pebs) ⊦ ⟪encode_vidheader#(m, vhdr; buf; err); if err = ESUCCESS then mtd_asm_write#(m0, m, 0, m, buf; pebs; err)⟫ mtd-cons(pebs)
Proof step 19:
pebs[m0] = mkpeb(buf, EB_PAGE_SIZE, false), m = EB_PAGE_SIZE, avhdr.valid?, m0 < # pebs, mtd-cons(pebs) ⊦ avhdr.valid? ∧ avhdr.valid? ∧ avhdr.valid? ∧ avhdr.valid? ∧ avhdr.valid?
