Proof step 74 from proof validrefs-putbar-01 (previous step)

¬ (r0 ≠ jvmref ∧ (¬ is_valid_ref(str, r0, putByteArray(bytes, r, i, st)) ∨ ¬ (putByteArray(bytes, r, i, st)[r0 -- _type]) .type ≤ ty)), validrefs(str, r0 ' + refs0, ty, putByteArray(bytes, r, i, st)), okbytearray(r, st), ∀ i, bytes, ty, r0, str, st, r, refs. # refs < # refs0 → (okbytearray(r, st) ∧ validrefs(str, r0 ' + refs, ty, putByteArray(bytes, r, i, st)) → junkref(str, r0, st) ∨ validrefs(str, r0 ' + refs, ty, st)) ⊦ validrefs(str, r0 ' + refs0, ty, st), junkref(str, r0, st)

And obtained the following new goals

Proof step 2:
⊦ validrefs(str, jvmref ' + refs, ty, st) ↔ refs = []
Proof step 73:
validrefs(str, r0 ' + refs0, ty, putByteArray(bytes, r, i, st)), okbytearray(r, st), is_valid_ref(str, r0, putByteArray(bytes, r, i, st)), st[r0 -- _type] .type ≤ ty, ∀ i, bytes, ty, r0, str, st, r, refs. # refs < # refs0 → (okbytearray(r, st) ∧ validrefs(str, r0 ' + refs, ty, putByteArray(bytes, r, i, st)) → junkref(str, r0, st) ∨ validrefs(str, r0 ' + refs, ty, st)) ⊦ r0 = jvmref, validrefs(str, r0 ' + refs0, ty, st), junkref(str, r0, st)
