//! CLI-surface coverage for the `durability.objects` escape hatch
//! (SPEC-OBJECTS §10.1). The key is honored by the object-store sync
//! policy, so it must also be settable and showable through `mkit
//! config` — regression for the review finding that
//! `mkit config durability.objects per-object` exited 78 with
//! "unknown config key".
#![allow(clippy::unwrap_used)] // unwrap is the assertion in test helpers
