 1// Package impl is the v1 implementation of the IBC host logic for the
 2// gno.land/r/onbloc/ibc/union/core proxy. The proxy keeps the stable identity
 3// (admin, package address), the Store, and the app registry; this realm holds
 4// the swappable protocol logic and is injected with the proxy-owned store
 5// (core.IStore) at install time.
 6//
 7// core/v1 implements the client, connection, channel, packet, app registry, and
 8// query surfaces behind the proxy's ICore interface.
