//! Authorization regression tests for the `relicario org` item commands.
//!
//! These cover two gaps the B9–B14 item-CRUD work left open:
//!   1. Grant-DENIAL on the read/mutate-by-query commands (`get`, `edit`, `rm`,
//!      `restore`, `purge`). Only `add` had a denial test before this. An
//!      ungranted member must be rejected by EVERY one of them, and `get` must
//!      not leak the item's plaintext.
//!   2. SecureNote body masking on `org get`, mirroring the Login-password
//!      masking already asserted in `org_items.rs`.
//!
//! The multi-member harness mirrors `org_lifecycle.rs`'s `Dev` pattern: each
//! `Dev` is an isolated XDG config home carrying its own ed25519 device key, so
//! a second member can be added with their OWN keypair and then attempt commands
//! against the shared vault.
