Proof step 53 from proof inv-lookup (previous step)

Heuristic symbolic execution applied rule if negative right

And obtained the following new goals

Proof step 54:
afs-cons(dirs, files), dcache-cons(dcache, dirs, files), icache-cons(icache, dirs, files), pcache-cons(pcache, dirs, files), synced(dirs, icache, pcache), p_ino ∈ dirs, ⌊err0⌋ , asynced1 → synced(files, icache, pcache), links(p_ino, dirs) ≠ ∅ ∨ p_ino = ROOT_INO ⊦ ⟪skip⟫ dcache-cons(dcache, dirs, files), dentrykey(p_ino, dent.name) ∈ dcache

Rule argument

pos: right 1
