lesavka/testing/tests/server_core_script_contract.rs

//! Contract tests for lesavka-core gadget rebuild guardrails.
//!
//! Scope: statically guard the shell logic in `scripts/daemon/lesavka-core.sh`.
//! Targets: incomplete gadget recovery behavior.
//! Why: the gadget can be bound but half-applied, and the core script must
//! rebuild that state instead of refusing reset forever.
