This field should always be present and defined after check() is
called. Declare the property but allow its initialization to be delayed
until check() so that it can be typed without the use of `Optional`.
This helps simplify typing by avoiding the need to interrogate the value
for None at multiple callsites; the overwhelming majority of uses assume
a fully-initialized object.
