- NluRouter in AiBot: builds permission-filtered flow catalog, asks AI to route user intent to exact flow key or return chat response - MediaTranscriber: downloads WA media, transcribes audio (Whisper/Gemini), extracts image intent (OpenAI/Gemini/Claude vision) - BotRouter hybrid: text → NormalBot → NLU fallback if no match; audio/image → transcribe → NLU route; sends transcript preview first - Admin IA tab: NLU checkbox with description - Per-company nlu flag saved in config_json Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
