Struct EnabledEditions 

pub struct EnabledEditions { /* private fields */ }

The editions enabled for writing in a session.

At most one edition is enabled per family. Enabling a newer or older edition from the same family replaces the previous selection. This is separate from EditionSession: registration describes what a session knows how to reason about, while enabling is the explicit writer policy.

Backed by an ArcSwapMap keyed by edition family, so clones observe the same selection and enabling an edition replaces the family’s previous entry.
