User uploads a file via **Form Trigger**.\n2. File is sent to two VLM Run agents:\n - Segmentation Agent\n - Detection Agent\n3. VLM Run returns signed Google Cloud Storage URLs.\n4. Webhooks receive the completed outputs.\n5. Code Node extracts the **full signed URL** (no trimming).\n6. n8n downloads the image using the signed URL.\n7. Final output is shared to:\n - **Google Drive**\n - **Gmail**\n - **Telegram**\n"
