treat constants more uniformly
...
We used to ignore constant inputs entirely. We now track them, but if we
find that a value is constant, we discard ITS inputs. This means that
-- if we track dependencies -- we have an "outer rim" of constant
values.
Also take the opportunity to reshuffle how derived inputs represent
their state.

The old setup acquired `upgradable_read` even when the value was cached.
At that point you might as well just a mutex.
