## 📞 Troubleshooting

**Q: Where's the code for [feature]?**  
A: It hasn't been built yet. Check [PHASE_TRACKER.md](PHASE_TRACKER.md) to see which sprint it's in.

**Q: Do I need to read all the docs?**  
A: Start with [README.md](README.md) + [PHASE_TRACKER.md](PHASE_TRACKER.md). Others are reference.

**Q: Can I skip a sprint?**  
A: No, they have dependencies. See dependency graph in [PHASE_TRACKER.md](PHASE_TRACKER.md).

**Q: What if I find a bug in the design?**  
A: File an issue + update [new_gap_analysis.md](new_gap_analysis.md) with the correction.

**Q: How do I track my progress?**  
A: Update [PHASE_TRACKER.md](PHASE_TRACKER.md) status columns as you go.
