One platform. Three integrated layers of clinical reasoning.
A clinical question is rarely answered from one source alone. Each pillar does a job no other pillar can do. The platform is what lets them work together.
Context
Ontologies, literature, regulatory labels, ecological variables, and curated medical knowledge. The same patient observation carries different meaning at different points in medical history. The context layer respects that, so an interpretation made today does not silently overwrite what was known yesterday. The foundation model has much of this built in by construction. The agent reaches for it explicitly when a deliverable needs citation.
Observed
Built today from the Harris data lake. Curated, nurtured, and continuously extended. The Foundational KG is the strategic asset that everything else is grown from. The foundation model is trained on it. Project Knowledge Galaxies are built using the same machinery. Every prediction and every claim ends in a traceable atom of the Foundational KG.
Expected
Trained on the Foundational KG. The model is a synthesis of experienced clinicians who have seen enough to have intuition about what is coming. Outputs are structured: predicted trajectories, candidate responders, cohort matches, digital twins, counterfactual interventions. Every output is a hypothesis to be tested against the observed data.
