Proof step 15 from proof replay-log-gc-copy (previous step)

# ax0 = # kx1, replay-log(ax0, fs[adr, fs[ri[key]]][ax0, fs[adr, fs[ri[key]]][ri[kx1]]], ri[key, adr] ⊖ ro) = ri[key, adr][kx1, ax0] ⊖ ro, ro.inodes?, new(ax0, fs), new(ax0, fs[adr, fs[ri[key]]]), orphans-cons(fs, ri, ro), ri-closed(ri, fs, ro), ri-cons(ri, fs), key ∈ ri, kx1.toSet ⊆ dom ri ⊦ replay-log(ax0, fs[ax0, fs[ri[kx1]]], ri[key, adr] ⊖ ro) = ri[key, adr][kx1, ax0] ⊖ ro, dups(kx1), dups(ax0), key ∈ kx1, adr ∈ fs, adr ∈ ax0

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

spec: aubifs-base name: write-shift seq: # ax = # ndx ⊦ ¬ adr ∈ ax → fs[adr, nd][ax, ndx] = fs[ax, ndx][adr, nd] subst: [ndx, ax, nd, adr, fs] → [fs[adr, fs[ri[key]]][ri[kx1]], ax0, fs[ri[key]], adr, fs] flags: <all paths>

Additional information

Used simplifier rules: ⊦ # fs[ax] = # ax; (s)% ⊦ # ri[kx] = # kx; (s) Used terms: fs[adr, fs[ri[key]]][ri[kx1]], ax0, fs[ri[key]], adr, fs
