Proof step 7 from proof fwd-inv-loghead (previous step)

(elems nx0 ∪ dom gstore0) ++ n = dom gstore ∪ ginval, ginval ∩ elems nx0 = ∅, ∀ n. n ∈ gstore \ ginval → inv((gstore \ ginval)[n]) ⊦ inv(gstore[n]), n ∈ ginval

User applied rule all left

And obtained the following new goals

Proof step 8:
(elems nx0 ∪ dom gstore0) ++ n = dom gstore ∪ ginval, ginval ∩ elems nx0 = ∅, n ∈ gstore \ ginval → inv((gstore \ ginval)[n]) ⊦ inv(gstore[n]), n ∈ ginval
