Prevention plans, for people who do not have cancer yet

Until now the engine had exactly one answer for a patient with no confirmed disease: "could not resolve disease." That is correct and useless. A person with chronic hepatitis C, or a confirmed Lynch syndrome carrier, has a real and actionable cancer risk long before there is anything to stage.

CHARTER §3 is now amended to cover them — specifically, HCP-mediated prevention and early-diagnosis recommendations for at-risk asymptomatic individuals: first-degree relatives, IARC Group 1 chronic infections, and occupational exposures.

How it works

A profile with no confirmed disease but at least one fired prevention-eligible red flag now routes to Prevention Plan generation instead of that dead-end warning. Same engine, same knowledge base, same citation requirements.

Every prevention pathway ships at least two tracks — the intervention, and an observation track for declining it. That is not a stylistic choice: presenting a single binding directive would break the non-device positioning in CHARTER §15.2 C4.

What is live

32 prevention case pages, covering all seven IARC Group 1 infectious etiologies (HCV, H. pylori, HBV, HPV, HIV, EBV, HTLV-1), hereditary carrier pilots, and occupational, chronic-condition and iatrogenic exposures. They are in the gallery and the plan-builder dropdown.

What was deliberately left out

Path B — prevention advice direct to a patient, with no clinician in the loop — is parked, because it would trigger re-classification as a medical device under §15.3.

The scope document says plainly that this is a narrowing to fit the current charter rather than the intended endpoint. Worth recording while it is still inconvenient to admit.
