Proof step 26 from proof fsync-err (previous step)

asynced0 ↔ false, files1[m] = mkfile(m0, md0, m1, content), files = files0, inode = inode0, m ∈ files1 ⊦ [if valid-file-inode(inode, dirs, files) then {fail_or_success#(; ; err); choose bv with true in asynced := bv} else abort] (err = ESUCCESS ∨ ⌊err⌋ )

Heuristic conditional right split applied rule if right

And obtained the following new goals
