## 🎓 How to Use Each Diagram Type

### C4 Architecture Diagrams
**What**: Hierarchical system decomposition (Context → Container → Component)  
**When**: Understanding architecture, planning changes, communicating with stakeholders  
**How**: Read top-down, one level per meeting/review

### Activity/Workflow Diagrams
**What**: Process flows and sequential steps  
**When**: Planning implementation, managing project phases  
**How**: Follow the flow, use as checklist for task tracking

### Sequence Diagrams
**What**: Detailed message flows between components  
**When**: Understanding specific interactions, debugging integration issues  
**How**: Read timeline left-to-right, note decision points

### Gantt Charts
**What**: Timeline and resource allocation  
**When**: Project planning, sprint planning, resource allocation  
**How**: Identify dependencies, adjust dates based on team size

### Dependency Graphs
**What**: File and module relationships  
**When**: Understanding refactoring scope, identifying impact areas  
**How**: Follow arrows to understand what changes what

## ✨ Highlights

### What Makes This Plan Special

1. **Complete C4 Architecture** - Context → Container → Component hierarchy
2. **Systematic Error Analysis** - 128 errors categorized into 4 types with known fixes
3. **Testable Milestones** - Each phase has clear success criteria
4. **Production-Ready Process** - Full release and monitoring plan included
5. **Implementation-Ready** - Exact commands and code examples provided
6. **Clear Timeline** - Realistic 11-12 day estimate with dependencies shown

### Key Innovations

- **Error Categorization**: Instead of viewing 128 errors as chaos, view them as 4 systematic categories
- **Phased Approach**: 8 phases that build on each other with testable milestones
- **Trust the Tests**: 107 existing tests give confidence that implementation is solid
- **Clear Blocker**: Single point of failure identified (line 15 of cmds/mod.rs) - easy to communicate

## 📌 Remember

**The key insight**: This is NOT a "rebuild from scratch" project. It's an "integration project" where:
- ✅ The marketplace-v2 crate is 100% complete
- ✅ Tests prove it works (107 PASSING)
- ❌ The CLI bridge isn't finished (128 errors blocking integration)

Fix the bridge → Full integration → Production ready
