st.info("""
**This test will determine:**

✅ **If Import Works:**
- Container Runtime supports modular architecture
- We can organize code into separate files  
- Ready for more complex POC development

❌ **If Import Fails:**
- Container Runtime requires single-file architecture (as suspected from Phase 0)
- Must use class-based organization within one file
- Proceed with single-file POC approach

**Either way, we have a clear path forward for POC development!**
