Companion Hub

What Companion Hub does, and the concepts behind it. These pages explain how things work — for step-by-step instructions, see Getting started or Guides.

The Companion stack, layer by layer Five layers of the platform drawn as isometric slabs stacked one above the next, each slab a true isometric rhombus with a visible edge, lit from high on the left so that the top face of every slab is the palest of its three and the left face the darkest. Lowest is Companion Core, the Framework Mini-ITX board in its steel chassis; above it Companion OS; then Companion Hub, held a full step deeper in the campaign’s phthalo green because it is the layer this plate is about; then Companion Memory and Agents; and on top an open plane carrying a four-by-three grid of twelve rounded tiles, one for each catalogue app: Companion Memory, OpenClaw, Hermes, Planning, Capture, Spellbook, Local Bench, Just In Case, Earth, Photo Time Machine, Web XR Scan and Glasses Bridge. Each tile carries a simple line mark drawn for this sheet — a node graph, a pincer, a paper dart, three checked rows, an arrow dropping into a tray, an open book, a gauge and needle, two rings on four spokes, a globe, a framed landscape, four scan brackets, and a pair of lenses under a signal arc — rather than the shipped icon artwork, which is raster and cannot be read at this size. Each slab carries its own name, set in the plane of its top face along the lower-left edge, with no description.

Where Hub sits: Companion Core hardware and Companion OS below it; Companion Memory, agents, and your apps on top.
