📚 I Want to Understand the Code (1 hour)

To learn how the pipeline works internally:

QUICK-START.md - Run it first (5 min)
CODE-READING-GUIDE.md - Learn to read code (30 min)
- Recommended reading order for all 5 source files
- Code pattern explanations with examples
- Trace a city through the entire pipeline
- Testing strategies
../docs/pipeline-guide.md - Full system overview (20 min)
- Architecture and data flow diagrams
- Description of each component
- Performance characteristics

🏗️ I Want to Understand the Architecture (1.5 hours)

To understand WHY the system was designed this way:

Read the above "Understand the Code" path first
../docs/pipeline-architecture.md - Design deep dive (30 min)
- 5 core design principles with trade-offs
- Detailed threading model (3-level hierarchy)
- Mutex contention analysis
- Future optimization opportunities
- Lessons learned

💻 I Want to Modify the Code (2+ hours)

To extend or improve the pipeline:

Complete the "Understand the Architecture" path above
Choose your enhancement:
- Add Real LLM: See "Future Implementation" in ../docs/pipeline-architecture.md
- Export Results: Modify src/main.cpp to write JSON
- Change Templates: Edit src/generator.cpp
- Add Features: Read inline code comments for guidance
