Your Age Check Returns Yes or No. The EU KIDS Act Needs Four Answers.
The Commission's KIDS Act proposal, unveiled on 16 September 2026, replaces the single age line with a staircase: no account under 13, a guardian-controlled account at 13 and 14, an independent account from 15, and a narrow parent-hosted route for younger children on kids' video platforms. Every one of those states has to be expressible in your schema, and one of them is not an age at all. It is a link to another person. Here is what changes in the data model, why 'unknown' stops being a safe default, and how a zero-knowledge age proof takes away the birthdate you would normally use to schedule the next transition.
