//! Purpose: JSON task-field comparison coverage for task command tests.
//!
//! Responsibilities:
//! - Validate unchanged-field detection.
//! - Validate changed-field detection for modified JSON values.
//! - Verify invalid JSON input surfaces errors.
//!
//! Scope:
//! - `task_cmd::compare_task_fields` behavior only.
//!
//! Usage:
//! - Uses `super::*;` to access the shared suite imports.
//!
//! Invariants/assumptions callers must respect:
//! - Tests cover JSON diff contract behavior only, not downstream update reporting.
