Proof step 1 from proof btree-inv-crash (conclusion)

⊦ istore0 ⊑ istore ∧ remove-refsize0(istore0) = istore0 ∧ btree-inv(rp, adr, istore, istore0, zh0, ri, fi) ∧ inv(istore) → btree-inv(null, adr, remove-refsize0(crash(istore, istore0)), istore0, zh1, fi, fi)

System applied rule normalize

And obtained the following new goals

Proof step 2:
remove-refsize0(istore0) = istore0, btree-inv(rp, adr, istore, istore0, zh0, ri, fi), inv(istore), istore0 ⊑ istore ⊦ btree-inv(null, adr, remove-refsize0(crash(istore, istore0)), istore0, zh1, fi, fi)
