# Verify network connectivity for external services
curl -f http://localhost:11434/api/tags  # Ollama
curl -f http://localhost:8080/health    # Server

Performance Test Failures

# Check system resources
free -h
top -bn1 | head -10

# Verify baseline performance
cargo run -p terraphim_benchmark -- --baseline-check

# Check for resource contention
ps aux | grep -E "(ollama|terraphim)" | grep -v grep

Integration Test Failures

# Verify service dependencies
docker ps | grep terraphim
netstat -tlnp | grep :8080

# Check service logs
tail -f terraphim_server.log
tail -f terraphim_agent.log

# Validate configuration consistency
diff config/server.toml config/test.toml

Cross-Platform Compatibility Issues

# Check platform-specific binaries
file target/release/terraphim_server
file target/release/terraphim_agent

# Verify platform detection
uname -a
cat /etc/os-release  # Linux
sw_vers              # macOS
systeminfo | findstr /B /C:"OS"  # Windows

Debugging Strategies

Log Analysis

# Enable debug logging
export RUST_LOG=debug
export TERRAPHIM_LOG_LEVEL=debug

# Follow test execution logs
tail -f target/debug/deps/test_output.log

# Analyze performance logs
grep "PERF:" terraphim_server.log | tail -20

Component Isolation

# Test individual components in isolation
cargo test -p terraphim_server --test unit_tests
cargo test -p terraphim_agent --test unit_tests

# Run integration tests with verbose output
cargo test -p terraphim_server --test integration -- --nocapture

Network Debugging

# Check network connectivity
