Proof step 35 from proof validrefs-putbar (previous step)

st[r -- _type] .type ≤ ty, okbytearray(r1, st), validrefs(`docs2store', r ' + acc, ty, putByteArray(bytes, r1, i, st)), is_array(`docs2store', r, 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) ⊦ r = jvmref, validrefs(`docs2store', r ' + acc, ty, st)

Proof step 5:
⊦ is_array(str, r, st) ∧ st[r -- _type] .type ≤ ty → ( validrefs(str, r ' + refs, ty, st) ↔ refs = [] ∨ (∃ i. 0 ≤ i ∧ i < st[r -- _length] .intval ∧ is_referencevalue(st[r -- i ']) ∧ refs .first = st[r -- i '] .refval ∧ validrefs(str, refs, st[r -- _type] .type .type, st)))
Proof step 34:
is_array(`docs2store', r, putByteArray(bytes, r1, i, st)) ∧ (putByteArray(bytes, r1, i, st)[r -- _type]) .type ≤ ty, st[r -- _type] .type ≤ ty, okbytearray(r1, st), acc = [] ∨ (∃ i0. 0 ≤ i0 ∧ i0 < (putByteArray(bytes, r1, i, st)[r -- _length]) .intval ∧ is_referencevalue(putByteArray(bytes, r1, i, st)[r -- i0 ']) ∧ acc .first = (putByteArray(bytes, r1, i, st)[r -- i0 ']) .refval ∧ validrefs(`docs2store', acc, (putByteArray(bytes, r1, i, st)[r -- _type]) .type .type, putByteArray(bytes, r1, i, st))), is_array(`docs2store', r, 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) ⊦ r = jvmref, validrefs(`docs2store', r ' + acc, ty, st)
