# Consoles & Maintenance Screens

## console role — a screen that is its own node

A computer next to a monitor (a 3x3 multiblock is a great size) adopted
as "console" runs the full FactoryOS desktop on that monitor — NODES,
SWITCHES, POWER, CONFIGURE, GUIDES — the same apps as the mainframe.

Everything is touch: tap an app button to open it, tap a list row to
select+activate, tap the upper/lower half of a scroll pane to page.
What touch can't do: type. Text fields (CONFIGURE editor) need a real
keyboard — use the mainframe terminal or a wireless pocket computer.

Each console is an independent node: if the mainframe dies the console
still renders, and it can command any reachable node directly.

## displaytile role — a window into the mainframe

Tiles pushed by the mainframe compositor show a rect of the main
screen. With tileX/tileY set to the tile's canvas origin, taps on the
tile are forwarded to the mainframe's window manager — the display
wall becomes an interactive surface, and a maintenance tile in the
server room is literally a window into the mainframe's screen.

Set master = "<mainframe node id>" on input devices (navpads, tiles) so
their touches target one node instead of every UI host on the channel.

## Suggested server room

mainframe + monitor (ops wall via tiles)
  + console computer + 3x3 monitor on the wall (walk-up terminal)
  + navpad pocket computer for floor work
