Proof step 2 from proof inodes-nodata (previous step)

ks.inodes?, datakey(ino, n) ∈ ks ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ ks.inodes? ↔ (∀ key. key ∈ ks → key.inode?)
Proof step 4:
datakey(ino, n) ∈ ks, ∀ key. key ∈ ks → key.inode? ⊦

Rule argument

spec: <toplevel> name: inode-set seq: ⊦ ks.inodes? ↔ (∀ key. key ∈ ks → key.inode?) subst: [ks] → [ks] flags: <all paths>
