 ## Web Chat over SSH
-- The relay hosts a loopback-only HTTP server (`clawdis webchat --port <port>`; default 18788).
-- The mac app forwards `127.0.0.1:<port>` over SSH (`ssh -L <ephemeral>:127.0.0.1:<port>`), loads `/webchat/info`, and serves the Web Chat UI in-app.
+- The relay hosts a loopback-only HTTP server (default 18788, see `webchat.port`).
+- The mac app forwards `127.0.0.1:<port>` over SSH (`ssh -L <ephemeral>:127.0.0.1:<port>`), then loads `/webchat/?session=<key>` in-app.
 - Keep the feature enabled in *Settings → Config → Web chat*. Disable it to hide the menu entry entirely.

 ## Troubleshooting
 - **exit 127 / not found**: `clawdis` isn’t on PATH for non-login shells. Add it to `/etc/paths`, your shell rc, or symlink into `/usr/local/bin`/`/opt/homebrew/bin`.
 - **Health probe failed**: check SSH reachability, PATH, and that Baileys is logged in (`clawdis status --json`).
-- **Web Chat stuck**: confirm the remote webchat server is running (`clawdis webchat --json`) and the port matches *Settings → Config*.
+- **Web Chat stuck**: confirm the relay is running on the remote host and `webchat.enabled` is true; ensure the forwarded port matches *Settings → Config*.
 - **Voice Wake**: trigger phrases are forwarded automatically in remote mode; no separate forwarder is needed.

 ## What shipped
-- A lightweight HTTP server now lives inside the Node relay (`clawdis webchat --port 18788`).
-- It binds to **127.0.0.1** only and serves:
-  - `GET /webchat/info?session=<key>` → `{port, token, sessionId, initialMessages, basePath}` plus history from the relay’s session store.
+- The relay now starts a loopback-only web chat server automatically (default port **18788**, configurable via `webchat.port`).
+- Endpoints:
+  - `GET /webchat/info?session=<key>` → `{port, sessionId, initialMessages, basePath}` plus history from the relay’s session store.
   - `GET /webchat/*` → static Web Chat assets.
   - `POST /webchat/rpc` → runs `clawdis agent --json` and returns `{ ok, payloads?, error? }`.
-- The macOS app embeds this UI in a WKWebView. In **remote mode** it first opens an SSH tunnel (`ssh -L <local>:127.0.0.1:<port>`) to the remote host, then loads `/webchat/info` through that tunnel.
-- Initial messages are preloaded from the relay’s session store, so remote sessions appear immediately.
-- Sending now goes over the HTTP `/webchat/rpc` endpoint (no more AgentRPC fallback).
-- Feature flag + port live in *Settings → Config → Web chat*. When disabled, the “Open Chat” menu entry is hidden.
+- The macOS app simply loads `http://127.0.0.1:<port>/webchat/?session=<key>` (or the SSH-forwarded port in remote mode). No Swift bridge is used for sends; all chat traffic stays inside the Node relay.
+- Initial messages are fetched from `/webchat/info`, so history appears immediately.
+- Enable/disable via `webchat.enabled` (default **true**); set the port with `webchat.port`.
 
 ## Security
 - Loopback only; remote access requires SSH port-forwarding.
-- Optional bearer token support is wired; tokens are returned by `/webchat/info` and accepted by `/webchat/rpc`.
+- No bearer token; the trust model is “local machine or your SSH tunnel”.
 
 ## Failure handling
 - Bootstrap errors show in-app (“Web chat failed to connect …”) instead of hanging.

 ## Dev notes
 - Static assets stay in `apps/macos/Sources/Clawdis/Resources/WebChat`; the server reads them directly.
 - Server code: `src/webchat/server.ts`.
-- CLI entrypoint: `clawdis webchat --json [--port N]`.
+- CLI entrypoint (optional): `clawdis webchat --json [--port N]` to query/start manually.
 - Mac glue: `WebChatWindow.swift` (bootstrap + tunnel) and `WebChatTunnel` (SSH -L).
