Proof step 45 from proof at-put-prim (previous step)

is_referencevalue(st[r0 -- sks]), fits(r0, sks, st) ⊦ sks = [], (st[r -- sk, val][r0 -- sks]) = st[r0 -- sks], is_referencevalue(st[r -- sk]), junkref(str, r, st), junkref(str, r0, st)

User applied rule structural induction

And obtained the following new goals

Proof step 44:
∀ st, r0, r, sk, val, str. is_referencevalue(st[r0 -- sks0]) ∧ fits(r0, sks0, st) → sks0 = [] ∨ (st[r -- sk, val][r0 -- sks0]) = st[r0 -- sks0] ∨ is_referencevalue(st[r -- sk]) ∨ junkref(str, r, st) ∨ junkref(str, r0, st), is_referencevalue(st[r0 -- (sk0 + sks0)]), fits(r0, sk0 + sks0, st) ⊦ sk0 + sks0 = [], (st[r -- sk, val][r0 -- (sk0 + sks0)]) = st[r0 -- (sk0 + sks0)], is_referencevalue(st[r -- sk]), junkref(str, r, st), junkref(str, r0, st)

Rule argument
