0.5.2

Added

• examples/aep/blocker.yaml, the eleventh ladder. engineering-protocols 0.18.0 added blocker — what is stopping something, typed by what would clear it. Upstream the type is the kind: credential-blocker and person-blocker share one ladder through their hyphen lineage.

  This kernel has no kind hierarchy, so the equivalence here is over the ladder itself, which is what the pinned document declares. story:schema-fragments is where a hierarchy would go, and it is worth saying that the adopter got the effect without one — their lineage rule is a naming convention their own type system reads, not something the definition format has to grow.
