研究方向

Start with the user_devices registry and the WebSocket hub’s h.clients[userID] mapping, then review dependency #178 and discuss an approach on a sub-issue before starting. The work spans server device registration, per-device encryption and message delivery, and app device linking and management. Done means each device has its own Signal identity and receives its own copy of every message.

描述

area: e2ee difficulty: hard enhancement

Goal

Today keys live on one device. Signing in elsewhere shows "Sent from another device" for messages you sent from the other phone, and only one live connection per user is kept. Multi-device means each device has its own Signal identity and receives its own copy of every message.

Starting point

  • user_devices already has a device_id column (currently always main).
  • The WebSocket hub keeps one connection per user (h.clients[userID]). This becomes per device.

Steps (sub-issues)

  1. Server: device registry and per-device prekey bundles.
  2. Fan-out: encrypt each message for every device of the recipient and your own other devices, and deliver per device.
  3. App: link a new device and manage devices.

Depends on the hub fix (#178). Please discuss your approach on a sub-issue before starting.
