Proof step 1 from proof replay-safe-gc-copy (conclusion)

# ax = # kx ⊦ ri-cons(ri, fs) ∧ kx.toSet ⊆ dom ri ∧ new(ax, fs) ∧ ¬ dups(ax) ∧ ¬ dups(kx) ∧ orphans-cons(fs, ri, ro) ∧ ri-closed(ri, fs, ro) ∧ ro.inodes? → replay-safe(ax, fs[ax, fs[ri[kx]]], ri ⊖ ro)

System applied rule normalize

And obtained the following new goals

Proof step 2:
# ax = # kx, ro.inodes?, new(ax, fs), orphans-cons(fs, ri, ro), ri-closed(ri, fs, ro), ri-cons(ri, fs), kx.toSet ⊆ dom ri ⊦ dups(kx), dups(ax), replay-safe(ax, fs[ax, fs[ri[kx]]], ri ⊖ ro)
