Domain Knowledge

Charter: Ground-up domain courses — the physics, architecture, and operations of the networks we model. Read these to understand what we are inventorying before you touch how we model it.

The platform is domain-agnostic, but the people building it are not allowed to be. These courses take you from first principles to the operational realities of each network we serve. They are full standalone lessons (built with the Vinxi design system) served alongside the Book.

The people and the buyers

The networks are operated by people and bought by organizations — knowing both is as much domain knowledge as knowing the physics:

Field Personas & the Trust Economy — the six archetypes behind 45 utility-network roles, their jobs and pains, the moments that decide the product, and how low-trust environments shape everything. Read before designing any capture, approval, dispatch, or dashboard surface.
The Buyer Landscape — what the operator organization needs beyond its user stories: the twin as a financial document, procurement psychology, and the adoption risks that live at the top.

Fiber / FTTx

The optical access network — from photons in glass to the GIS digital twin that inventories it. Start here if you are working on the fiber data model, splicing, or outside-plant topology.

Oil & Gas Networks

The hydrocarbon value chain — upstream gathering, processing, transmission, and the last-mile distribution grid, plus the SCADA and integrity systems that run it.
