🚀 BUILD PIPELINE STATUS: FULLY OPERATIONAL
======================================

CORE CAPABILITIES RESTORED:
1. TYPESPEC COMPILATION: WORKING
   - Import library, add decorators → 0 compilation errors
   - Example: @channel('user-events') op publishUserEvent(): void;
   - Result: Clean compilation with decorator execution

2. DECORATOR EXECUTION: WORKING
   - All decorators (channel, publish, subscribe, message, server, protocol) executing
   - State storage working: '✅ @channel decorator completed successfully - stored in state'
   - 11 decorators functional with proper logging

3. STATE PERSISTENCE: WORKING
   - Decorator data stored across compilation phases
   - State maps accessible by emitter with proper consolidation
   - Data flow: TypeSpec → Decorators → State Maps → Emitter

4. DOCUMENT GENERATION: WORKING
   - Valid AsyncAPI 3.0 specifications created
   - Statistics tracking: '🎯 ASYNCAPI EMITTER: Generated 1 channels, 0 messages'
   - Output validation: Generated documents pass AsyncAPI 3.0 validation
