Public profile boundaries

Public Beta Trust boundary

Participant Trust is separate from official identity facts.

Signed-in Public Beta participants may allocate virtual Trust Points to technically eligible current members. Those allocations are participant-generated simulation data: they are not official ratings, are not inferred from this profile, and do not imply endorsement, affiliation, or voting intent.

Signals shown here are not polls, odds, forecasts, donations, or financial assets.
