- The draft lists 18 signals with hazard ratios, evidence grades and citations; its governance process is proposed, with the founding committee still being formed.
Field notes
The reference model runs in the browser: visitors can start with an example person or adjust values, and the page says entered data stays on the page. Its draft specification scores signals against an average person of the same age and sex, discounts overlap and converts the result using a Gompertz base of 1.09. The linked materials include JSON and test vectors; the governance rules are described as a proposal, with the founding committee still being formed.
