Proof step 2 from proof py-last (previous step)

ispath(p, ino, m, dirs, files), py(user, p, ino, dirs, files) ⊦ px(user, meta(ε, m, dirs, files))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
⊦ ispath(p, ino, m, dirs, files) ∧ py(user, p, ino, dirs, files) → px(user, p, ino, dirs, files)
Proof step 4:
ispath(p, ino, m, dirs, files), px(user, p, ino, dirs, files), py(user, p, ino, dirs, files) ⊦ px(user, meta(ε, m, dirs, files))

Rule argument

Additional information

Used simplifier rules: py-px: ⊦ ispath(p, ino, m, dirs, files) ∧ py(user, p, ino, dirs, files) → px(user, p, ino, dirs, files);
