Proof step 2 from proof eexists (conclusion)

⊦ ¬ ⌊EEXISTS⌋

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ ⌊err⌋ ↔ err ≠ ESUCCESS ∧ err ≠ EEXISTS ∧ err ≠ ENOENT ∧ err ≠ EISDIR ∧ err ≠ ENOTEMPTY ∧ err ≠ ENOTDIR ∧ err ≠ EBADFD ∧ err ≠ EACCESS

Rule argument
