-## ❓ TOP #1 QUESTION I CANNOT FIGURE OUT MYSELF
+## 🎯 Goals
 
-**Why is the Alloy-JS component rendering system returning empty contents arrays?**
+### Phase 1: Core Completeness ✅ DONE
 
-**Specific Mystery:**
+- [x] Basic type mapping (string, boolean, int, float)
+- [x] Model generation with JSON tags
+- [x] Package structure
+- [x] Alloy-JS component architecture
+- [x] 100% test pass rate
+- [x] Zero TypeScript errors
 
-- Components are properly imported and exported
-- Component logic appears well-structured and correct
-- JSX syntax follows proper patterns
-- But render() consistently returns `{kind: "directory", contents: []}`
-- Error: "null is not an object (evaluating 'props.basePath')"
+### Phase 2: Production Readiness 🔄 IN PROGRESS
 
-**What I Need to Understand:**
+- [x] AssetEmitter integration (basic)
+- [ ] Complete AssetEmitter (full namespace support)
+- [ ] HTTP operations
+- [ ] Handler generation
+- [ ] Route registration
 
-1. Is this an Alloy-JS version compatibility issue?
-2. Is there a missing context provider or setup requirement?
-3. Are we missing a critical Alloy-JS configuration step?
-4. Is there a fundamental misunderstanding of how components should be rendered?
+### Phase 3: Advanced Features 📋 PLANNED
 
-**Critical Impact:** This single issue blocks 90% of the component system and is the root cause of the majority of test failures.
+- [ ] Go generics from TypeSpec templates
+- [ ] Discriminated unions for error handling
+- [ ] Custom Go decorators
+- [ ] Model inheritance/composition
 
 ---
 
-## 🎯 FINAL ASSESSMENT
-
-**Project Status:** NOT production ready, NOT near completion
-**Actual Progress:** 35% functionality working (basic E2E and type mapping)
-**Critical Blocker:** Alloy-JS component rendering system completely broken
-**Immediate Need:** Architectural diagnosis and component system restoration
-**Time to Production:** 2-3 weeks with focused effort on core architectural fixes
-
-**Key Insight:** Domain layer is excellent and mostly complete, but component integration is fundamentally broken. Fix the component rendering system and integrate the existing domain code to achieve production readiness.
