Proof step 4:
⊦ is_obj(str, r, st) ∧ st[r -- _type] .type ≤ ty → ( validrefs(str, r ' + refs, ty, st) ↔ refs = [] ∨ (∃ fs. fs ' ∈ instfields(st[r -- _type] .type .class) ∧ is_referencevalue(st[r -- fs ']) ∧ refs .first = st[r -- fs '] .refval ∧ validrefs(str, refs, fs .type, st)))
Proof step 36:
¬ (is_obj(`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)), is_valid_ref(`docs2store', r, putByteArray(bytes, r1, i, st)), st[r -- _type] .type ≤ ty, ∀ 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 52:
is_obj(`docs2store', r, putByteArray(bytes, r1, i, st)) ∧ (putByteArray(bytes, r1, i, st)[r -- _type]) .type ≤ ty, okbytearray(r1, st), acc = [] ∨ (∃ fs. fs ' ∈ instfields((putByteArray(bytes, r1, i, st)[r -- _type]) .type .class) ∧ is_referencevalue(putByteArray(bytes, r1, i, st)[r -- fs ']) ∧ acc .first = (putByteArray(bytes, r1, i, st)[r -- fs ']) .refval ∧ validrefs(`docs2store', acc, fs .type, putByteArray(bytes, r1, i, st))), is_valid_ref(`docs2store', r, putByteArray(bytes, r1, i, st)), st[r -- _type] .type ≤ ty, ∀ 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)
