Proof step 2 from proof crash-neutral-recover (previous step)

psynced, root.dir?, fids-cons(root, fs, ofh), posix-crash(root, fs, ofh, tree, fs0, ofh0) ⊦ ⟨posix_recover#(psynced0; root, fs, ofh; psynced, err)⟩ (psynced ∧ posix-crash(root, fs, ofh, tree, fs0, ofh0))

Heuristic nonrecursive calls applied rule call right

And obtained the following new goals

Proof step 3:
⊦
Proof step 4:
psynced, root.dir?, fids-cons(root, fs, ofh), posix-crash(root, fs, ofh, tree, fs0, ofh0) ⊦ ⟨fail_or_success#(; ; err); if err ≠ ESUCCESS then root := ?, fs := ?, ofh := ?, psynced := ? else psynced := true⟩ (psynced ∧ posix-crash(root, fs, ofh, tree, fs0, ofh0))

Rule argument
