Somewhere to get the hard decisions wrong.
Somewhere High School is wholly synthetic. No real pupil data is used anywhere on this page, no pupil is voiced, and nothing you type is stored. This is rehearsal, not prediction — a design prototype of one slice, not evidence that the approach works.
The interactive case needs JavaScript. It runs the Wholesight loop — Ground, See, Name, Act, Weigh — over a seeded synthetic S3 attendance cohort, in about five minutes.
