+  the PC that reaches it, which cannot read that machine's load.
+- Reference: no app listed in `src/AGENTS.md` shows a machine's load in its project list that I
+  know of (they assume one machine); this follows the app's own plan meters and PC group header,
+  and differs only in measuring a PC instead of a subscription. No code is borrowed.

PC names distinguish results, and Recent remembers each pane's PC. Picking a result opens that PC and pane directly. Disconnected PCs are omitted; app and plugin actions remain on the currently selected PC.

Pick or type a terminal-only command and send normally: after acceptance, the pane's terminal opens over the chat, in this browser only, with **Back to Chat** and **Keep Terminal**; the chat stays where you were reading. For Claude Code's panels (`/config`, `/permissions`, `/theme` and the like) the chat may come back by itself when you close the panel, once Claude records the close; for Codex, omp, pi, gjc, OmO, Hermes (classic CLI), Devin, agy and Grok it comes back after their recorded pickers and panels, once the agent's empty input row is back on the screen; otherwise use **Back to Chat**, the header's Chat, or Back on a phone.

Messages the PC sends by itself at the end of a turn are not held. Automatic queued delivery never changes your view.
