>
> Add an optimistic versioning verification stage into our write path. The
> write should start as it normally does. If the version was included on the
> entity write operation (delete or write) we need to read back the entity log,
> and ensure that our "new" version is the only version entry since the last
> commit.
> If not, fail fast, signal to the user their entity is "stale".
