Module layouts 

Alternate main-view layouts (PR-UI-6).

• Wall — orchestrator overview. Up to 4 agent tiles in a 2×2 grid (or 1×N stack on narrow terminals). >4 agents scroll the grid vertically per Alireza’s v2-locked answer.
• MailboxFirst — channel-list / feed / participants horizontal split, for triaging mailbox traffic across the team when the operator’s focus is communication-first rather than one-agent-deep.

Both layouts share the same statusline below them; both are reachable from the Triptych layout via Ctrl+W / Ctrl+M.
