2. Voice messages are transcribed automatically using OpenAI Whisper
3. Detects special commands — staff survey triggers and survey responses

5. Checks for waitlist offer responses
6. AI Agent (Claude Haiku) processes the request using 7 tool sub-workflows
7. Response is split and sent back via WhatsApp
