ralph-agent-loop 0.4.0

//! Tests for `edit.rs` operations (`apply_task_edit` and parsing/validation behavior).
//!
//! Responsibilities:
//! - Validate edit behavior and error context for task updates.
//! - Cover success paths and key failure modes for edits.
//!
//! Does not handle:
//! - Integration with on-disk queue persistence or CLI parsing.
//! - End-to-end GUI edit flows.
//!
//! Assumptions/invariants:
//! - Helper builders in this module construct valid baseline tasks.
//! - Errors are surfaced as user-facing strings.
