+# TypeSpec AsyncAPI Emitter - Comprehensive Execution Plan (125 Tasks)
+
+**Plan Date:** 2024-12-30  
+**Total Tasks:** 125  
+**Total Estimated Effort:** 125 hours (16 working days)  
+**Planning Methodology:** Pareto-Optimal Execution
+
+---
+
+## 📊 EXECUTIVE SUMMARY
+
+### Current State
+- **Status:** CRITICAL - Emitter Completely Broken
+- **Core Issue:** State maps return empty despite decorators executing
+- **Secondary Issue:** Emitter uses wrong APIs (fs instead of emitFile)
+- **Production Value:** ZERO - Cannot be used
+
+### Goal
+- **Target:** Working, Type-Safe, Production-Ready v1.0.0 Emitter
+- **Timeline:** 16 working days (125 hours)
+- **Approach:** Critical → Major → MVP → Complete
+
+### Strategy
+1. **Phase 1 (2.25 hours):** Fix critical state management - unlock 51% functionality
+2. **Phase 2 (3.75 hours):** Fix emitter integration - unlock 64% functionality
+3. **Phase 3 (25 hours):** Build working MVP - unlock 80% functionality
+4. **Phase 4 (94 hours):** Complete production-ready emitter - 100%

+## ⚠️ RISKS & MITIGATIONS
+
+### Risk 1: State Management Not Fixable
+**Likelihood:** Low (10%)  
+**Impact:** Critical (blocks everything)  
+**Mitigation:** Deep TypeSpec compiler research, consider alternative approaches
+
+### Risk 2: Timeline Overrun
+**Likelihood:** Medium (40%)  
+**Impact:** High (delays release)  
+**Mitigation:** Prioritize critical tasks, defer non-essential features
+
+### Risk 3: TypeSpec API Changes
+**Likelihood:** Low (15%)  
+**Impact:** Medium (requires rework)  
+**Mitigation:** Follow TypeSpec emitter conventions, use stable APIs
+
+### Risk 4: Resource Constraints
+**Likelihood:** Medium (30%)  
+**Impact:** Medium (delays completion)  
+**Mitigation:** Flexible task ordering, adapt to constraints
