Server-Sent Events (SSE) endpoint for clients that prefer HTTP streaming over SignalR (React, Vue, curl, Axios, etc.). GET /mentor/chat?message=hello — text-only POST /mentor/chat { "message": "...", — text + image attachments (roadmap \#13); "attachments": \[ … \] } a base64 image never fits in a query string. Response format: text/event-stream data: {"type":"chunk","text":"Hello","aiGenerated":true} data: {"type":"cards","cards":\[…\]} data: {"type":"navigation","url":"/orders"} data: {"type":"confirmationRequired","actionId":"…","tool":"…","message":"…"} data: {"type":"completed","aiGenerated":true} data: {"type":"error","message":"..."}

Every frame beyond `chunk`/`completed`/`error` is **additive**: a client that does not know a `type` ignores it and still receives the whole answer as text. That is what lets the protocol grow without breaking the three-frame clients the README has always shown.
