Ports and addresses

Address	What
codeflower://HOST:PORT?token=TOKEN	a sandbox; paste into VS Code or the app’s Add remote sandbox. Anyone with it controls the agent
http://127.0.0.1:7720/?key=…	the app’s window, served only to this computer (another port when 7720 is taken)
http://127.0.0.1:7720/#add=codeflower%3A%2F%2F…	adds a sandbox to the running app, in one click
vscode://codeflower.codeflower/connect?address=codeflower://…	connects VS Code to a sandbox, after asking
http://HOST:PORT/?key=…	a sandbox’s own chat page, with --server
https://tunnels.codeflower.app/p#…	a one-time pairing link (10 minutes)
https://tunnels.codeflower.app/m/ID/	the app’s page through the tunnel, for paired browsers

A sandbox’s port is any free port unless --port sets one. With Docker and Podman it is published on 127.0.0.1 only; with Apptainer it listens on the node, and the printed address is the node’s (--host, --advertise-host change this).
