`Writable`内部のMapped typeで再構成されると`Weirdo`の原型が消滅してしまい、`HitWeakenEntry`にかからなくなるのだと思います。
↑これは若干不正確で、正確には以下のような作用です。 1. `SCO`を計算するときに 2. `Writeable`の計算が走る (結果を`X`とする) 3. `Weirdo`の原型が失われる 4. `X`は`Weirdo`ではないので、`HitWeakenEntry`にかからなくなる 5. `Int16Array`のプロパティが散らかされて大変なことになる
> I tacked this and couldn't get to a perfectly working implementation. 😇 As mentioned above, we should only narrow in then-branch of `include` checks but it doesn't seem currently...
I think the above is one of the best thing that we can have, as same "properties" are shown in following minimized case: 
Are there reason to not use `aka.ms` for the future? The domain seems point anything under your control for me with desired sub-path (and shorter).
