"""
Integration Tests: Multi-Organelle Workflows
============================================

Tests that verify multiple organelles working together in realistic workflows.
These tests focus on the interactions between organelles to ensure the "cell"
functions as a cohesive system.

Organelles tested:
- Membrane: Request filtering and rate limiting
- Mitochondria: Safe expression evaluation and tool execution
- Ribosome: Prompt template engine
- Nucleus: LLM provider wrapper (using MockProvider)
- Chaperone: Output validation and JSON folding
- Lysosome: Error and waste handling
