- sidebar: workspaces (+ sessions) of every other device appear inside the stock Workspaces list with a server icon and the device name; click folds sessions, hover + creates a session there, a session opens as the remote conversation view (/r/<device>/#/session/<id>); the viewed device's own rows stay native - Devices tab: every device with its state (online/offline, last seen, platform, workspace/session/running counts), offline and revoked devices included - deploy/e2e-dom.mjs, e2e-eval.mjs: DOM dump / evaluate-in-page helpers
