  ## ✨ Features

  * **ChatGPT Passthrough** - Added a ChatGPT passthrough route on the OpenAI integration with dedicated request handling
  * **User-Agent Tracking** - Track user agents on LLM and MCP logs, with custom user-agent mapping and dashboard dimension rankings
  * **Edge Agent MCP Log Ingestion** - MCP tool logs observed by the Bifrost Edge agent can now be ingested with device, app key, decision, and source attribution
  * **Edge Fallback Pages** - Added fallback pages for Bifrost Edge control views (config, devices, inventory) backed by governance resolver support
  * **Agent Handover View** - Added an agent handover page with seeded end-to-end data support

  ## 🐞 Fixed

  * **API Auth Bypass** - Stopped `/api/devices` bypassing auth via the `/api/dev` prefix
  * **Bedrock Error Types** - Surface the AWS exception type (`X-Amzn-Errortype`) on non-streaming Bedrock error responses instead of dropping it
