Proof step 57 from proof fits-put-01 (previous step)

is_referencevalue(st[r -- sks]), okarray(r1, byte_type, st), fits(r, sks, st), r1 ∈ st, is_valid_ref(str, r, st) ⊦ r1 = jvmref, r = jvmref, fits(r, sks, st[r1 -- i ', byteval(by)]), junkref(str, r, st)

User applied rule structural induction

And obtained the following new goals

Proof step 3:
⊦ fits(r, [], st)
Proof step 56:
∀ st, r, r1, str, i, by. is_referencevalue(st[r -- sks0]) ∧ okarray(r1, byte_type, st) ∧ fits(r, sks0, st) ∧ r1 ∈ st ∧ is_valid_ref(str, r, st) → r1 = jvmref ∨ r = jvmref ∨ fits(r, sks0, st[r1 -- i ', byteval(by)]) ∨ junkref(str, r, st), is_referencevalue(st[r -- (sk + sks0)]), okarray(r1, byte_type, st), fits(r, sk + sks0, st), r1 ∈ st, is_valid_ref(str, r, st) ⊦ r1 = jvmref, r = jvmref, fits(r, sk + sks0, st[r1 -- i ', byteval(by)]), junkref(str, r, st)
