PiCloud/crates/picloud-cli/tests/apply_ownership.rs

//! §7 multi-repo ownership — the claim, end to end via `pic`.
//!
//! A `[project]` claims a group node on first apply; the SAME project re-applies
//! freely; a DIFFERENT project applying to that node is refused (409) unless it
//! `--takeover`s (which requires group-admin). An app inherits ownership from
//! its nearest claimed ancestor group. `pic groups ls` shows the owning
//! project's slug. The pure claim policy is unit-tested in manager-core; this
//! journey pins the wire + CLI + authz interaction.
