//! BUG-008: Placeholder Text in Reports - RED Phase Tests
//!
//! These tests verify that context reports do NOT contain placeholder text.
//!
//! Current Status: 🔴 RED - These tests will FAIL until placeholders removed
//!
//! Test Strategy (Extreme TDD):
//! 1. RED: Write failing tests that verify no placeholders
//! 2. GREEN: Remove placeholder sections from utility_handlers.rs
//! 3. REFACTOR: Ensure clean code
//! 4. COMMIT: Single atomic commit with fix
