Proof step 55 from proof validrefs-putbar (previous step)

okbytearray(r1, st), validrefs(`docs2store', r ' + acc, ty, putByteArray(bytes, r1, i, st)), ∀ r1, st, ty, bytes, i. okbytearray(r1, st) ∧ validrefs(`docs2store', acc, ty, putByteArray(bytes, r1, i, st)) → validrefs(`docs2store', acc, ty, st) ⊦ validrefs(`docs2store', r ' + acc, ty, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ r ≠ jvmref ∧ (¬ is_valid_ref(str, r, st) ∨ ¬ st[r -- _type] .type ≤ ty) → ¬ validrefs(str, r ' + refs, ty, st)
Proof step 54:
¬ (r ≠ jvmref ∧ (¬ is_valid_ref(`docs2store', r, putByteArray(bytes, r1, i, st)) ∨ ¬ (putByteArray(bytes, r1, i, st)[r -- _type]) .type ≤ ty)), okbytearray(r1, st), validrefs(`docs2store', r ' + acc, ty, putByteArray(bytes, r1, i, st)), ∀ r1, st, ty, bytes, i. okbytearray(r1, st) ∧ validrefs(`docs2store', acc, ty, putByteArray(bytes, r1, i, st)) → validrefs(`docs2store', acc, ty, st) ⊦ validrefs(`docs2store', r ' + acc, ty, st)
