Proof step 36 from proof putbar-classfield-onlymod (previous step)

st[r -- _type] .type = mkclasstype(class), st[r -- sk] = refval(r1), okbytearray(r1, st), sk ∈ instfields(class) ⊦ st[r1 -- sk0] = (putByteArray(bytes, r1, st)[r1 -- sk0]), r = r1, r = jvmref, junkref(str, r, st), path∃(str, r, r1, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ path∃(str, r, r0, st) ↔ (∃ refs. refs ≠ [] ∧ refs .first = r ∧ refs .last = r0 ∧ validrefs(str, refs, st[r -- _type] .type, st))
Proof step 35:
st[r -- _type] .type = mkclasstype(class), st[r -- sk] = refval(r1), okbytearray(r1, st), sk ∈ instfields(class) ⊦ st[r1 -- sk0] = (putByteArray(bytes, r1, st)[r1 -- sk0]), r = r1, r = jvmref, junkref(str, r, st), ∃ refs. refs ≠ [] ∧ refs .first = r ∧ refs .last = r1 ∧ validrefs(str, refs, st[r -- _type] .type, st)
