SpineWorkspace doctrine defines how the product works at the interaction and projection level. It is the layer of doctrine that governs what a user sees, what Twin can do, and how domains stay coherent.

​
The Interaction Model

  • One workbench — one interaction surface for every domain.
  • Focus assembles context — the entity in view triggers context assembly.
  • Twin proposes, humans approve, capabilities act — no direct writes outside this loop.
  • Every domain is a projection — never a separate app.

​
The Four Flows

Every domain surfaces four flows: Human Workbench, AI Workbench, System Flow, Execution Flow. All four are grounded in the shared Spine Fabric.
