Proof step 59 from proof fits-put-01 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ r ≠ jvmref ∧ ¬ is_valid_ref(str, r, st) → junkref(str, r, st)
Proof step 58:
¬ (r ≠ jvmref ∧ ¬ is_valid_ref(str, r, st)), is_referencevalue(st[r -- sks]), okarray(r1, byte_type, st), fits(r, sks, st), r1 ∈ st ⊦ r1 = jvmref, fits(r, sks, st[r1 -- i ', byteval(by)]), junkref(str, r, st)

Rule argument
