//! Comprehensive Integration Tests - STRICT FAILURE POLICY
//!
//! MANDATORY INTEGRATION TEST REQUIREMENTS:
//! - These tests use REAL Anthropic API endpoints - NO MOCKING ALLOWED
//! - Tests MUST FAIL IMMEDIATELY if API secrets are not available (no graceful fallbacks)
//! - Tests MUST FAIL IMMEDIATELY on network connectivity issues
//! - Tests MUST FAIL IMMEDIATELY on API authentication failures
//! - Tests MUST FAIL IMMEDIATELY on any API endpoint errors
//! - NO SILENT PASSES allowed when problems occur
//!
//! Run with : cargo test --features integration
//! Requires : Valid `ANTHROPIC_API_KEY` in environment or ../../secret/-secrets.sh
