# WS Gateway

Stateless WebSocket proxy. Accepts Electron connections, authenticates JWT,
routes frames to Chat/Batch services via Redis pub/sub.

## No business logic
This service does NOT know what tasks, notes, or agents are.
It only routes JSON frames between Electron and downstream services.

## Scaling
Sticky sessions on `user_id` (Traefik consistent hashing).

## Redis channels used
- Subscribe: `ws:out:{user_id}` (frames to send to client)
- Publish: `chat:request:{user_id}`, `batch:request:{user_id}`
- LPUSH: `tool:result:{call_id}` (from client tool_result frames)
- HSET/HDEL: `ws:devices:{user_id}` (device registry)
