# `gno.land/p/moul/authz/v1`

Flexible authorization control for privileged actions, **backed by a B+ tree**
(`gno.land/p/nt/bptree` via [`p/moul/addrset/v1`](https://github.com/moul/gno-contracts/tree/main/p/moul/addrset/v1)).

The B+ tree successor to [`p/moul/authz/v0`](https://github.com/moul/gno-contracts/tree/main/p/moul/authz/v0)
(AVL-backed, via `p/moul/addrset/v0`). **v1 because the member store — and thus
the on-chain storage layout — changed** (a compatibility change ⇒ new version).
The exported API matches v0, except the `MemberAuthority.Tree()` escape hatch is
removed so the backing store never leaks across realms.
