The traits do not change between products — only the projection does. What makes that safe is the correction loop: the model can be overruled by the person it describes.
A projection layer decides which dimensions matter, how they are weighted, and what vocabulary the output uses. It never rewrites the underlying trait or its evidence.
A profile that exists from minute one, so "swiping" turns into "talking".
Translating feelings that cannot be said out loud into language that can be examined.
Reading cooperation and friction between people, instead of between job titles.
Most systems treat a user's disagreement as noise to be smoothed over. Here it is the highest-weight signal available — because the person being modelled is the only one who can actually check the claim.
Personal baseline is more suitable for a long-term human model than population averages. Individual behaviour should be modelled relative to a person's own historical baseline, not a generic mean.
We separate what is proven from what we merely propose. Where a claim is still a hypothesis, it is labelled as one — including on pages like this.
