Proof step 119 from proof inv-truncate (previous step)

files[m] = mkfile(m1, md1, # links(m, dirs), content0), afs-cons(dirs, files), m ∈ files, ⌊err0⌋ , buf-opt.some? → # buf-opt.buf = VFS_PAGE_SIZE ⊦ ⟪err := err0; asynced := ?⟫ true

Heuristic symbolic execution applied rule assign right

And obtained the following new goals
