WebChat (Gateway WebSocket UI)

Status: the macOS/iOS SwiftUI chat UI talks directly to the Gateway WebSocket.

What it is

• A native chat UI for the gateway (no embedded browser and no local static server).
• Uses the same sessions and routing rules as other channels.
• Deterministic routing: replies always go back to WebChat.

Quick start

1. Start the gateway.
2. Open the WebChat UI (macOS/iOS app) or the Control UI chat tab.
3. Ensure gateway auth is configured (required by default, even on loopback).

How it works (behavior)

• The UI connects to the Gateway WebSocket and uses chat.history, chat.send, and chat.inject.
• chat.inject appends an assistant note directly to the transcript and broadcasts it to the UI (no agent run).
• Aborted runs can keep partial assistant output visible in the UI.
• Gateway persists aborted partial assistant text into transcript history when buffered output exists, and marks those entries with abort metadata.
• History is always fetched from the gateway (no local file watching).
• If the gateway is unreachable, WebChat is read-only.

Remote use

• Remote mode tunnels the gateway WebSocket over SSH/Tailscale.
• You do not need to run a separate WebChat server.

Channel options:

• No dedicated webchat.* block. WebChat uses the gateway endpoint + auth settings below.

Related global options:

• gateway.port, gateway.bind: WebSocket host/port.
• gateway.auth.mode, gateway.auth.token, gateway.auth.password: WebSocket auth (token/password).
• gateway.auth.mode: "trusted-proxy": reverse-proxy auth for browser clients (see Trusted Proxy Auth).
• gateway.remote.url, gateway.remote.token, gateway.remote.password: remote gateway target.
• session.*: session storage and main key defaults.
