//! Purpose: invalid and edge-case lifecycle transition coverage.
//!
//! Responsibilities:
//! - Verify terminal tasks cannot be started again.
//! - Verify `task ready` only applies to draft tasks.
//!
//! Scope:
//! - CLI failure and no-op transition behavior.
//!
//! Usage:
//! - Imported by `task_lifecycle_test.rs`; relies on `use super::*;` for shared fixtures and helpers.
//!
//! Invariants/assumptions callers must respect:
//! - Tests preserve existing error assertions and queue-state checks.
//! - Terminal-task fixtures continue to come from suite-local helpers.
