Proof step 60 from proof validrefs-putbyte (previous step)

validrefs(str, refs, ty, st), okbytearray(r, st), ∀ by, i, ty, str, st, r, refs0. # refs0 < # refs → (okbytearray(r, st) ∧ validrefs(str, refs0, ty, st) → validrefs(str, refs0, ty, st[r -- i ', byteval(by)])) ⊦ validrefs(str, refs, ty, st[r -- i ', byteval(by)])

User applied rule cut formula

And obtained the following new goals

Proof step 1:
⊦ validrefs(str, [], ty, st)
Proof step 59:
validrefs(str, refs, ty, st), okbytearray(r, st), ∀ by, i, ty, str, st, r, refs0. # refs0 < # refs → (okbytearray(r, st) ∧ validrefs(str, refs0, ty, st) → validrefs(str, refs0, ty, st[r -- i ', byteval(by)])) ⊦ refs = [], validrefs(str, refs, ty, st[r -- i ', byteval(by)])

Rule argument

[fma-arg: refs = []]
