Proof step 1 from proof in-ri-inode-data (conclusion)

⊦ inodekey(ino) ∈ ri[datakey(ino, n), adr] ↔ inodekey(ino) ∈ ri

Heuristic simplifier applied rule simplifier

And closed the goal!

Rule argument

Additional information

Used simplifier rules: ⊦ inodekey(m) ≠ datakey(m0, m1); (s)% ⊦ key ∈ ri[key0, adr] ↔ key = key0 ∨ key ∈ ri; (ws)
