Proof step 55 from proof fits-put-short (previous step)

is_shortvalue(st[r1 -- fs ']), fits(r, sks, st) ⊦ (st[r1 -- fs ', val][r -- sks]) = st[r -- sks], junkref(str, r, st)

User applied rule structural induction

And obtained the following new goals

Proof step 54:
∀ st, r1, fs, r, val, str. is_shortvalue(st[r1 -- fs ']) ∧ fits(r, sks0, st) → (st[r1 -- fs ', val][r -- sks0]) = st[r -- sks0] ∨ junkref(str, r, st), is_shortvalue(st[r1 -- fs ']), fits(r, sk + sks0, st) ⊦ (st[r1 -- fs ', val][r -- (sk + sks0)]) = st[r -- (sk + sks0)], junkref(str, r, st)

Rule argument
