Proof step 63 from proof inv-writemeta (previous step)

afs-cons(dirs, files), ispath(p, ROOT_INO, ino0, dirs, files), of-cons(of, dirs, files), px-parent(user, p, ROOT_INO, dirs, files), ⌊err0⌋ , ino0 ∈ dirs ∨ ino0 ∈ files ⊦ ⟪if err0 = ESUCCESS then if pw(user, inode.meta) then {inode.meta := md; afs_check_commit#(dirs, files; err0; asynced); if err0 = ESUCCESS then afs_write_inode#(inode; err0, dirs, files; asynced)} else err := EACCESS⟫ (of-cons(of, dirs, files) ∧ afs-cons(dirs, files))

Heuristic symbolic execution applied rule if negative right

And obtained the following new goals

Proof step 64:
afs-cons(dirs, files), ispath(p, ROOT_INO, ino0, dirs, files), of-cons(of, dirs, files), px-parent(user, p, ROOT_INO, dirs, files), ⌊err0⌋ , ino0 ∈ dirs ∨ ino0 ∈ files ⊦ ⟪skip⟫ (of-cons(of, dirs, files) ∧ afs-cons(dirs, files))

Rule argument

pos: right 1
