//! Endpoint Catalog Verification Tests
//!
//! Tests that verify the endpoint catalog is complete and accurate.
//!
//! # TDD Phase: RED
//! This test is written FIRST, before -endpoint_catalog.md exists.
//! Expected to fail with: "No such file or directory"
//!
//! # Rulebook Compliance
//! - test_organization.rulebook.md: Test in tests/ directory ✓
//! - code_style.rulebook.md: 2-space indentation ✓
//! - codebase_hygiene.rulebook.md: Clear test name ✓
//! - files_structure.rulebook.md: Checked readme.md, no overlap ✓
