# `gno.land/r/moul/x/upgrade/schema/impl/v1`

Version 1 of the **handler realm** of pattern G. Adds `surround` and keeps both of
[`v0`](../gen0)s verbs untouched, which is what lets the facade accept it: growing
the API costs no new realm and no new signature at the permanent path.

Also carries the twin of `adminreg`s dispatch-cost test.

See [the pattern](../../README.md) and [the exploration](../../../README.md).
