An actor's effective kind, treating the absent field as its default. Throws
a TypeError for a present kind, null included, that is not a
PRINCIPAL_KINDS member, which must never read as the human default.
Structurally typed rather than taking Actor so this leaf does not depend on
the barrel that re-exports it.
