Listener — drive the standalone CLI from the web terminal

Run trading commands from the in-app web CLI but have them execute in the standalone CLI process on your local machine. The standalone keeps the account streams open, holds the chasers, runs the hooks; the web tab is just a remote keyboard. Use this when you want the standalone to host the session (persistent connections, hooks, simulation state) and the web tab for the convenience of the browser UI.

Minimum viable​

In the standalone REPL — nothing to do. The listener binds 127.0.0.1:53219 automatically at startup (provided listener.enabled is not false).

In the web CLI tab, set the target dropdown to listener. The first connection from this browser triggers a one-time approval prompt in the standalone REPL. Approve and every subsequent command typed in the web tab runs in the standalone process.

Variations​

# In the standalone REPL — see what's connected
clients

Lists trusted browsers (one per clientId). Revoke via clients revoke <id-prefix> (prefix ≥ 8 chars).

# In the standalone REPL — confirm the listener is up
> # no command needed; the listener is implicit
> # check via /health from outside:
$ curl http://127.0.0.1:53219/health
{ "ok": true, "pid": ..., "port": 53219 }
# In the standalone REPL — disable the bridge entirely
> # edit ~/.tealstreet/config.json:
{ "listener": { "enabled": false } }

Kills the loopback server. Web tabs targeting listener will fail with a connect error.

# In the standalone REPL — keep streams but reject commands
> # ~/.tealstreet/config.json:
{ "listener": { "remoteExec": false } }

State frames (state:accounts, state:tasks, state:hooks) continue; inbound cmd:exec is rejected. Useful as a panic-button toggle.

# In the standalone REPL — turn off account sync
> # ~/.tealstreet/config.json:
{ "listener": { "accountSync": false } }

Stops broadcasting/accepting account snapshots — web tabs no longer mirror the standalone's account list.

Gotchas​

  • Listener is loopback-only. The standalone binds 127.0.0.1:53219 — it's not reachable from the LAN. To run the listener on a different machine from the browser, you need a tunnel (Cloudflare, ssh -L, etc.).
  • The 75-second client-hint timer: if no client connects within 75 s of listener startup, the standalone prints a one-line refresh hint. This is timed to be slightly above the web reconnect ceiling (60 s) so it doesn't fire on every soft-reload.
  • Approval is per browser tab namespace, keyed by a clientId UUID stored in the browser. Wipe browser storage → approval prompt fires again on next connect.
  • The first frame from the web client must be a hello. If you're poking at this from a script, see Listener wire frames for the protocol.
  • When you switch web targets back to worker (the default), the web tab goes back to running commands in its own safe-cex worker — the standalone keeps running but no longer sees the web's keystrokes. Streams it owned (chasers, TWAPs, hooks) keep going.
  • Commands run via the listener use the standalone's accounts, not the web's. If your standalone has account A selected and your web tab thinks the active account is B, the cmd:exec frame can carry an account override; without it the standalone uses its own focus.
  • Output streams as cmd:output frames — for ; and & chains, late frames can arrive after cmd:done. Don't treat cmd:done as a hard end-of-output marker.
