Proof step 139 from proof replayone-prog (previous step)

boolvar ↔ boolvar0, fs[adr] = truncnode(inodekey(ino), m), key = inodekey(ino), ks = datakeys(key, n, ri), n = m, ri0 = ri, adr ∈ fs ⊦ ⟪ri := ri \ ks⟫ (ri = replay-one(adr, fs[adr], ri0)), adr ∈ ri

Heuristic symbolic execution applied rule assign right

And closed the goal!

Rule argument

Additional information

Used simplifier rules: ⊦ replay-one(adr, truncnode(key, n), ri) = ri \ datakeys(key, n, ri); (s)
