cellos-ctl 0.5.6

//! Wave 2 red-team — wire-shape compatibility pin (HIGH-W2D-2).
//!
//! `cellos-server::state::FormationRecord` serialises its lifecycle
//! field as `status` (UPPERCASE enum). `cellctl::model::Formation`
//! historically declared the field as `state`, so deserialisation
//! silently produced an empty string and every `cellctl get formations`
//! row rendered with a blank STATE column. The wave-2 fix adds
//! `#[serde(alias = "status")]` so both shapes deserialise into the same
//! field. This test pins that behaviour at the public-API level so a
//! future drive-by edit that removes the alias breaks at test time, not
//! the next time someone runs `cellctl get formations` against a real
//! server.
